When we conduct moderated research, like user interviews or usability tests, for our clients, we encourage them to observe as many sessions as possible. We find when clients see us interview their users, and get real-time responses, they’re able to learn about the needs of their users in real-time and be more active participants in the process. One way we help clients feel engaged with the process during remote sessions is to establish a real-time communication backchannel that empowers clients to flag responses they’d like to dig into further and to share their ideas for follow-up questions.

There are several benefits to establishing a communication backchannel for moderated sessions:

• Everyone on the team, including both internal and client team members, can be actively involved throughout the data collection process rather than waiting to passively consume findings.
• Team members can identify follow-up questions in real-time which allows the moderator to incorporate those questions during the current session, rather than just considering them for future sessions.
• Subject matter experts can identify more detailed and specific follow-up questions that the moderator may not think to ask.
• Even though the whole team is engaged, a single moderator still maintains control over the conversation which creates a consistent experience for the participant.

If you’re interested in creating your own backchannel, here are some tips to make the process work smoothly:

• Use the chat tool that is already being used on the project. In most cases, we use a joint Slack workspace for the session backchannel but we’ve also used Microsoft Teams.
• Create a dedicated channel like #moderated-sessions. Conversation in this channel should be limited to backchannel discussions during sessions. This keeps the communication consolidated and makes it easier for the moderator to stay focused during the session.
• Keep communication limited. Channel participants should ask basic questions that are easy to consume quickly. Supplemental commentary and analysis should not take place in the dedicated channel.
• Use emoji responses. The moderator can add a quick thumbs up to indicate that they’ve seen a question.

Introducing backchannels for communication during remote moderated sessions has been a beneficial change to our research process. It not only provides an easy way for clients to stay engaged during the data collection process but also increases the moderator’s ability to focus on the most important topics and to ask the most useful follow-up questions.

Concurrency is the notion of multiple things happening at the same time. This is generally achieved either via time-slicing, or truly in parallel if multiple CPU cores are available to the host operating system. We've all experienced a lack of concurrency, most likely in the form of an app freezing up when running a heavy task. UI freezes don't necessarily occur due to the absence of concurrency — they could just be symptoms of buggy software — but software that doesn't take advantage of all the computational power at its disposal is going to create these freezes whenever it needs to do something resource-intensive. If you've profiled an app hanging in this way, you'll probably see a report that looks like this:

Anything related to file I/O, data processing, or networking usually warrants a background task (unless you have a very compelling excuse to halt the entire program). There aren't many reasons that these tasks should block your user from interacting with the rest of your application. Consider how much better the user experience of your app could be if instead, the profiler reported something like this:

Analyzing an image, processing a document or a piece of audio, or writing a sizeable chunk of data to disk are examples of tasks that could benefit greatly from being delegated to background threads. Let's dig into how we can enforce such behavior into our iOS applications.

A Brief History

In the olden days, the maximum amount of work per CPU cycle that a computer could perform was determined by the clock speed. As processor designs became more compact, heat and physical constraints started becoming limiting factors for higher clock speeds. Consequentially, chip manufacturers started adding additional processor cores on each chip in order to increase total performance. By increasing the number of cores, a single chip could execute more CPU instructions per cycle without increasing its speed, size, or thermal output. There's just one problem...

How can we take advantage of these extra cores? Multithreading.

Multithreading is an implementation handled by the host operating system to allow the creation and usage of n amount of threads. Its main purpose is to provide simultaneous execution of two or more parts of a program to utilize all available CPU time. Multithreading is a powerful technique to have in a programmer's toolbelt, but it comes with its own set of responsibilities. A common misconception is that multithreading requires a multi-core processor, but this isn't the case — single-core CPUs are perfectly capable of working on many threads, but we'll take a look in a bit as to why threading is a problem in the first place. Before we dive in, let's look at the nuances of what concurrency and parallelism mean using a simple diagram:

In the first situation presented above, we observe that tasks can run concurrently, but not in parallel. This is similar to having multiple conversations in a chatroom, and interleaving (context-switching) between them, but never truly conversing with two people at the same time. This is what we call concurrency. It is the illusion of multiple things happening at the same time when in reality, they're switching very quickly. Concurrency is about dealing with lots of things at the same time. Contrast this with the parallelism model, in which both tasks run simultaneously. Both execution models exhibit multithreading, which is the involvement of multiple threads working towards one common goal. Multithreading is a generalized technique for introducing a combination of concurrency and parallelism into your program.

The Burden of Threads

A modern multitasking operating system like iOS has hundreds of programs (or processes) running at any given moment. However, most of these programs are either system daemons or background processes that have very low memory footprint, so what is really needed is a way for individual applications to make use of the extra cores available. An application (process) can have many threads (sub-processes) operating on shared memory. Our goal is to be able to control these threads and use them to our advantage.

Historically, introducing concurrency to an app has required the creation of one or more threads. Threads are low-level constructs that need to be managed manually. A quick skim through Apple's Threaded Programming Guide is all it takes to see how much complexity threaded code adds to a codebase. In addition to building an app, the developer has to:

• Responsibly create new threads, adjusting that number dynamically as system conditions change
• Manage them carefully, deallocating them from memory once they have finished executing
• Leverage synchronization mechanisms like mutexes, locks, and semaphores to orchestrate resource access between threads, adding even more overhead to application code
• Mitigate risks associated with coding an application that assumes most of the costs associated with creating and maintaining any threads it uses, and not the host OS

This is unfortunate, as it adds enormous levels of complexity and risk without any guarantees of improved performance.

Grand Central Dispatch

iOS takes an asynchronous approach to solving the concurrency problem of managing threads. Asynchronous functions are common in most programming environments, and are often used to initiate tasks that might take a long time, like reading a file from the disk, or downloading a file from the web. When invoked, an asynchronous function executes some work behind the scenes to start a background task, but returns immediately, regardless of how long the original task might takes to actually complete.

A core technology that iOS provides for starting tasks asynchronously is Grand Central Dispatch (or GCD for short). GCD abstracts away thread management code and moves it down to the system level, exposing a light API to define tasks and execute them on an appropriate dispatch queue. GCD takes care of all thread management and scheduling, providing a holistic approach to task management and execution, while also providing better efficiency than traditional threads.

Let's take a look at the main components of GCD:

What've we got here? Let's start from the left:

• DispatchQueue.main: The main thread, or the UI thread, is backed by a single serial queue. All tasks are executed in succession, so it is guaranteed that the order of execution is preserved. It is crucial that you ensure all UI updates are designated to this queue, and that you never run any blocking tasks on it. We want to ensure that the app's run loop (called CFRunLoop) is never blocked in order to maintain the highest framerate. Subsequently, the main queue has the highest priority, and any tasks pushed onto this queue will get executed immediately.
• DispatchQueue.global: A set of global concurrent queues, each of which manage their own pool of threads. Depending on the priority of your task, you can specify which specific queue to execute your task on, although you should resort to using default most of the time. Because tasks on these queues are executed concurrently, it doesn't guarantee preservation of the order in which tasks were queued.

Notice how we're not dealing with individual threads anymore? We're dealing with queues which manage a pool of threads internally, and you will shortly see why queues are a much more sustainable approach to multhreading.

Serial Queues: The Main Thread

As an exercise, let's look at a snippet of code below, which gets fired when the user presses a button in the app. The expensive compute function can be anything. Let's pretend it is post-processing an image stored on the device.

At first glance, this may look harmless, but if you run this inside of a real app, the UI will freeze completely until the loop is terminated, which will take... a while. We can prove it by profiling this task in Instruments. You can fire up the Time Profiler module of Instruments by going to Xcode > Open Developer Tool > Instruments in Xcode's menu options. Let's look at the Threads module of the profiler and see where the CPU usage is highest.

We can see that the Main Thread is clearly at 100% capacity for almost 5 seconds. That's a non-trivial amount of time to block the UI. Looking at the call tree below the chart, we can see that the Main Thread is at 99.9% capacity for 4.43 seconds! Given that a serial queue works in a FIFO manner, tasks will always complete in the order in which they were inserted. Clearly the compute() method is the culprit here. Can you imagine clicking a button just to have the UI freeze up on you for that long?

Background Threads

How can we make this better? DispatchQueue.global() to the rescue! This is where background threads come in. Referring to the GCD architecture diagram above, we can see that anything that is not the Main Thread is a background thread in iOS. They can run alongside the Main Thread, leaving it fully unoccupied and ready to handle other UI events like scrolling, responding to user events, animating etc. Let's make a small change to our button click handler above:

Unless specified, a snippet of code will usually default to execute on the Main Queue, so in order to force it to execute on a different thread, we'll wrap our compute call inside of an asynchronous closure that gets submitted to the DispatchQueue.global queue. Keep in mind that we aren't really managing threads here. We're submitting tasks (in the form of closures or blocks) to the desired queue with the assumption that it is guaranteed to execute at some point in time. The queue decides which thread to allocate the task to, and it does all the hard work of assessing system requirements and managing the actual threads. This is the magic of Grand Central Dispatch. As the old adage goes, you can't improve what you can't measure. So we measured our truly terrible button click handler, and now that we've improved it, we'll measure it once again to get some concrete data with regards to performance.

Looking at the profiler again, it's quite clear to us that this is a huge improvement. The task takes an identical amount of time, but this time, it's happening in the background without locking up the UI. Even though our app is doing the same amount of work, the perceived performance is much better because the user will be free to do other things while the app is processing.

You may have noticed that we accessed a global queue of .userInitiated priority. This is an attribute we can use to give our tasks a sense of urgency. If we run the same task on a global queue of and pass it a qos attribute of background , iOS will think it's a utility task, and thus allocate fewer resources to execute it. So, while we don't have control over when our tasks get executed, we do have control over their priority.

A Note on Main Thread vs. Main Queue

You might be wondering why the Profiler shows "Main Thread" and why we're referring to it as the "Main Queue". If you refer back to the GCD architecture we described above, the Main Queue is solely responsible for managing the Main Thread. The Dispatch Queues section in the Concurrency Programming Guide says that "the main dispatch queue is a globally available serial queue that executes tasks on the application’s main thread. Because it runs on your application’s main thread, the main queue is often used as a key synchronization point for an application."

The terms "execute on the Main Thread" and "execute on the Main Queue" can be used interchangeably.

Concurrent Queues

So far, our tasks have been executed exclusively in a serial manner. DispatchQueue.main is by default a serial queue, and DispatchQueue.global gives you four concurrent dispatch queues depending on the priority parameter you pass in.

Let's say we want to take five images, and have our app process them all in parallel on background threads. How would we go about doing that? We can spin up a custom concurrent queue with an identifier of our choosing, and allocate those tasks there. All that's required is the .concurrent attribute during the construction of the queue.

Running that through the profiler, we can see that the app is now spinning up 5 discrete threads to parallelize a for-loop.

Parallelization of N Tasks

So far, we've looked at pushing computationally expensive task(s) onto background threads without clogging up the UI thread. But what about executing parallel tasks with some restrictions? How can Spotify download multiple songs in parallel, while limiting the maximum number up to 3? We can go about this in a few ways, but this is a good time to explore another important construct in multithreaded programming: semaphores.

Semaphores are signaling mechanisms. They are commonly used to control access to a shared resource. Imagine a scenario where a thread can lock access to a certain section of the code while it executes it, and unlocks after it's done to let other threads execute the said section of the code. You would see this type of behavior in database writes and reads, for example. What if you want only one thread writing to a database and preventing any reads during that time? This is a common concern in thread-safety called Readers-writer lock. Semaphores can be used to control concurrency in our app by allowing us to lock n number of threads.

Notice how we've effectively restricted our download system to limit itself to k number of downloads. The moment one download finishes (or thread is done executing), it decrements the semaphore, allowing the managing queue to spawn another thread and start downloading another song. You can apply a similar pattern to database transactions when dealing with concurrent reads and writes.

Semaphores usually aren't necessary for code like the one in our example, but they become more powerful when you need to enforce synchronous behavior whille consuming an asynchronous API. The above could would work just as well with a custom NSOperationQueue with a maxConcurrentOperationCount, but it's a worthwhile tangent regardless.

Finer Control with OperationQueue

GCD is great when you want to dispatch one-off tasks or closures into a queue in a 'set-it-and-forget-it' fashion, and it provides a very lightweight way of doing so. But what if we want to create a repeatable, structured, long-running task that produces associated state or data? And what if we want to model this chain of operations such that they can be cancelled, suspended and tracked, while still working with a closure-friendly API? Imagine an operation like this:

This would be quite cumbersome to achieve with GCD. We want a more modular way of defining a group of tasks while maintaining readability and also exposing a greater amount of control. In this case, we can use Operation objects and queue them onto an OperationQueue, which is a high-level wrapper around DispatchQueue. Let's look at some of the benefits of using these abstractions and what they offer in comparison to the lower-level GCI API:

• You may want to create dependencies between tasks, and while you could do this via GCD, you're better off defining them concretely as Operation objects, or units of work, and pushing them onto your own queue. This would allow for maximum reusability since you may use the same pattern elsewhere in an application.
• The Operation and OperationQueue classes have a number of properties that can be observed, using KVO (Key Value Observing). This is another important benefit if you want to monitor the state of an operation or operation queue.
• Operations can be paused, resumed, and cancelled. Once you dispatch a task using Grand Central Dispatch, you no longer have control or insight into the execution of that task. The Operation API is more flexible in that respect, giving the developer control over the operation's life cycle.
• OperationQueue allows you to specify the maximum number of queued operations that can run simultaneously, giving you a finer degree of control over the concurrency aspects.

The usage of Operation and OperationQueue could fill an entire blog post, but let's look at a quick example of what modeling dependencies looks like. (GCD can also create dependencies, but you're better off dividing up large tasks into a series of composable sub-tasks.) In order to create a chain of operations that depend on one another, we could do something like this:

So why not opt for a higher level abstraction and avoid using GCD entirely? While GCD is ideal for inline asynchronous processing, Operation provides a more comprehensive, object-oriented model of computation for encapsulating all of the data around structured, repeatable tasks in an application. Developers should use the highest level of abstraction possible for any given problem, and for scheduling consistent, repeated work, that abstraction is Operation. Other times, it makes more sense to sprinkle in some GCD for one-off tasks or closures that we want to fire. We can mix both OperationQueue and GCD to get the best of both worlds.

The Cost of Concurrency

DispatchQueue and friends are meant to make it easier for the application developer to execute code concurrently. However, these technologies do not guarantee improvements to the efficiency or responsiveness in an application. It is up to you to use queues in a manner that is both effective and does not impose an undue burden on other resources. For example, it's totally viable to create 10,000 tasks and submit them to a queue, but doing so would allocate a nontrivial amount of memory and introduce a lot of overhead for the allocation and deallocation of operation blocks. This is the opposite of what you want! It's best to profile your app thoroughly to ensure that concurrency is enhancing your app's performance and not degrading it.

We've talked about how concurrency comes at a cost in terms of complexity and allocation of system resources, but introducing concurrency also brings a host of other risks like:

• Deadlock: A situation where a thread locks a critical portion of the code and can halt the application's run loop entirely. In the context of GCD, you should be very careful when using the dispatchQueue.sync { } calls as you could easily get yourself in situations where two synchronous operations can get stuck waiting for each other.
• Priority Inversion: A condition where a lower priority task blocks a high priority task from executing, which effectively inverts their priorities. GCD allows for different levels of priority on its background queues, so this is quite easily a possibility.
• Producer-Consumer Problem: A race condition where one thread is creating a data resource while another thread is accessing it. This is a synchronization problem, and can be solved using locks, semaphores, serial queues, or a barrier dispatch if you're using concurrent queues in GCD.
• ...and many other sorts of locking and data-race conditions that are hard to debug! Thread safety is of the utmost concern when dealing with concurrency.

Hopefully this article gives you a lay of the land when it comes to multithreading techniques on iOS, and how you can use some of them in your app. We didn't get to cover many of the lower-level constructs like locks, mutexes and how they help us achieve synchronization, nor did we get to dive into concrete examples of how concurrency can hurt your app. We'll save those for another day, but you can dig into some additional reading and videos if you're eager to dive deeper.

“Close your eyes and name three people who have impacted the tech industry.”

In all likelihood, that list might be overwhelmingly white and male.

And you are not alone. Numerous lists online yielded the same results. In recent years, many articles have chronicled the dearth of diversity in tech. Studies have shown the ways in which venture capital firms have systematically underestimated and undervalued innovation coming particularly from women of color. In 2016 only 88 tech startups were led by African American women, in 2018 this number had climbed to a little over 200. Between 2009 and 2017, African American women raised $289MM in venture/angel funding. For perspective, this only represents .0006% of the $424.7B in total tech venture funding raised in that same time frame. In 2018, only 34 African American women had ever raised more than a million in venture funding.

When it comes to innovation, it is not unusual for financial value to be the biggest predictor of what is considered innovative. In fact, a now largely controversial list posted by Forbes of America’s most innovative leaders in the fall of 2019 featured 99 men and one woman. Ironically, what was considered innovative was, in fact, very traditional in its presentation. The criteria used for the list was “media reputation for innovation,” social connections, a track record for value creation, and investor expectations for value creation.

The majority of African American women-led startups raise $42,000 from largely informal networks. Criteria weighted on the side of ‘track record for value creation’ and ‘investor expectations for value creation’ devalues the immense contributions of African American women leading the charge on thoughtful and necessary tech. Had Forbes used criteria for innovation that recognized emergent leadership, novel problem-solving, or original thinking outside the circles of already well-known and well-established entrepreneurs we might have learned something new. Instead, we're basically reminded that "it takes money to make money."

Meanwhile, African American women are the fastest-growing demographic of entrepreneurs in the United States. Their contributions to tech, amongst other fields, are cementing the importance of African American women in the innovation space. And they are doing this within and outside traditional tech frameworks. By becoming familiar with these entrepreneurs and their work, we can elevate their reputation and broaden our collective recognition of innovative leaders.

In honor of black history month, we have compiled a list of African American women founders leading the way in tech innovation from Alabama to the Bay Area. From rethinking energy to debt forgiveness platforms these women are crossing boundaries in every field.

In my last post, I covered what LiveView is at a high level. In this series, we’re going to dive deeper and implement a LiveView powered Markdown editor called Frampton. This series assumes you have some familiarity with Phoenix and Elixir, including having them set up locally. Check out Elizabeth’s three-part series on getting started with Phoenix for a refresher.

This series has a companion repository published on GitHub. Get started by cloning it down and switching to the starter branch. You can see the completed application on master. Our goal today is to make a Markdown editor, which allows a user to enter Markdown text on a page and see it rendered as HTML next to it in real-time. We’ll make use of LiveView for the interaction and the Earmark package for rendering Markdown. The starter branch provides some styles and installs LiveView.

Rendering Markdown

Let’s set aside the LiveView portion and start with our data structures and the functions that operate on them. To begin, a Post will have a body, which holds the rendered HTML string, and title. A string of markdown can be turned into HTML by calling Post.render(post, markdown). I think that just about covers it!

First, let’s define our struct in lib/frampton/post.ex:

Now the failing test (in test/frampton/post_test.exs):

Our render method will just be a wrapper around Earmark.as_html!/2 that puts the result into the body of the post. Add {:earmark, "~> 1.4.3"} to your deps in mix.exs, run mix deps.get and fill out render function:

Our test should now pass, and we can render posts! [Note: we’re using the as_html! method, which prints error messages instead of passing them back to the user. A smarter version of this would handle any errors and show them to the user. I leave that as an exercise for the reader…] Time to play around with this in an IEx prompt (run iex -S mix in your terminal):

Great! That’s exactly what we’d expect. You can find the final code for this in the render_post branch.

LiveView Editor

Now for the fun part: Editing this live!

First, we’ll need a route for the editor to live at: /editor sounds good to me. LiveViews can be rendered from a controller, or directly in the router. We don’t have any initial state, so let's go straight from a router.

First, let's put up a minimal test. In test/frampton_web/live/editor_live_test.exs:

This test doesn’t do much yet, but notice that it isn’t live view specific. Our first render is just the same as any other controller test we’d write. The page’s content is there right from the beginning, without the need to parse JavaScript or make API calls back to the server. Nice.

To make that test pass, add a route to lib/frampton_web/router.ex. First, we import the LiveView code, then we render our Editor:

Now place a minimal EditorLive module, in lib/frampton_web/live/editor_live.ex:

And we have a passing test suite! The ~L sigil designates that LiveView should track changes to the content inside. We could keep all of our markup in this render/1 method, but let’s break it out into its own template for demonstration purposes.

Move the contents of render into lib/frampton_web/templates/editor/show.html.leex, and replace EditorLive.render/1 with this one liner: def render(assigns), do: FramptonWeb.EditorView.render("show.html", assigns). And finally, make an EditorView module in lib/frampton_web/views/editor_view.ex:

Our test should now be passing, and we’ve got a nicely separated out template, view and “live” server. We can keep markup in the template, helper functions in the view, and reactive code on the server. Now let’s move forward to actually render some posts!

Handling User Input

We’ve got four tasks to accomplish before we are done:

1. Take markdown input from the textarea
2. Send that input to the LiveServer
3. Turn that raw markdown into HTML
4. Return the rendered HTML to the page.

Event binding

To start with, we need to annotate our textarea with an event binding. This tells the liveview.js framework to forward DOM events to the server, using our liveview channel. Open up lib/frampton_web/templates/editor/show.html.leex and annotate our textarea:

<textarea phx-keyup="render_post"></textarea>

This names the event (render_post) and sends it on each keyup. Let’s crack open our web inspector and look at the web socket traffic. Using Chrome, open the developer tools, navigate to the network tab and click WS. In development you’ll see two socket connections: one is Phoenix LiveReload, which polls your filesystem and reloads pages appropriately. The second one is our LiveView connection. If you let it sit for a while, you’ll see that it's emitting a “heartbeat” call. If your server is running, you’ll see that it responds with an “ok” message. This lets LiveView clients know when they've lost connection to the server and respond appropriately.

Now, type some text and watch as it sends down each keystroke. However, you’ll also notice that the server responds with a “phx_error” message and wipes out our entered text. That's because our server doesn’t know how to handle the event yet and is throwing an error. Let's fix that next.

Event handling

We’ll catch the event in our EditorLive module. The LiveView behavior defines a handle_event/3 callback that we need to implement. Open up lib/frampton_web/live/editor_live.ex and key in a basic implementation that lets us catch events:

The first argument is the name we gave to our event in the template, the second is the data from that event, and finally the socket we’re currently talking through. Give it a try, typing in a few characters. Look at your running server and you should see a stream of events that look something like this:

There’s our keystrokes! Next, let’s pull out that value and use it to render HTML.

Rendering Markdown

Lets adjust our handle_event to pattern match out the value of the textarea:

def handle_event("render_post", %{"value" => raw}, socket) do

Now that we’ve got the raw markdown string, turning it into HTML is easy thanks to the work we did earlier in our Post module. Fill out the body of the function like this:

If you type into the textarea you should see output that looks something like this:

Perfect! Lastly, it’s time to send that rendered html back to the page.

Returning HTML to the page

In a LiveView template, we can identify bits of dynamic data that will change over time. When they change, LiveView will compare what has changed and send over a diff. In our case, the dynamic content is the post body.

Open up show.html.leex again and modify it like so:

Refresh the page and see:

Whoops!

The @post variable will only be available after we put it into the socket’s assigns. Let’s initialize it with a blank post. Open editor_live.ex and modify our mount/3 function:

In the future, we could retrieve this from some kind of storage, but for now, let's just create a new one each time the page refreshes. Finally, we need to update the Post struct with user input. Update our event handler like this:

Let's load up http://localhost:4000/editor and see it in action.

Nope, that's not quite right! Phoenix won’t render this as HTML because it’s unsafe user input. We can get around this (very good and useful) security feature by wrapping our content in a raw/1 call. We don’t have a database and user processes are isolated from each other by Elixir. The worst thing a malicious user could do would be crash their own session, which doesn’t bother me one bit.

Check the edit_posts branch for the final version.

Conclusion

That’s a good place to stop for today. We’ve accomplished a lot! We’ve got a dynamically rendering editor that takes user input, processes it and updates the page. And we haven’t written any JavaScript, which means we don’t have to maintain or update any JavaScript. Our server code is built on the rock-solid foundation of the BEAM virtual machine, giving us a great deal of confidence in its reliability and resilience.

In the next post, we’ll tackle making a shared editor, allowing multiple users to edit the same post. This project will highlight Elixir’s concurrency capabilities and demonstrate how LiveView builds on them to enable some incredible user experiences.

The classic adage is “good design speaks for itself.” Which would mean that if something’s as good of an idea as you think it is, a client will instantly see that it’s good too, right?

Here at Viget, we’re always working with new and different clients. Each with their own challenges and sensibilities. But after ten years of client work, I can’t help but notice a pattern emerge when we’re trying to get approval on especially cool, unconventional parts of a design.

So let’s break down some of those patterns to hopefully better understand why clients hesitate, and what strategies we’ve been using lately to help get the work we’re excited about approved.

Imagine this: the parallax homepage with elements that move around in surprising ways or a unique navigation menu that conceptually reinforces a site’s message. The way the content cards on a page will, like, be literal cards that will shuffle and move around. Basically, any design that feels like an exciting, novel challenge, will need the client to “get it.” And that often turns out to be the biggest challenge of all.

There are plenty of practical reasons cool designs get shot down. A client is usually more than one stakeholder, and more than the team of people you’re working with directly. On any project, there’s an amount of telephone you end up playing. Or, there’s always the classic foes: budgets and deadlines. Any idea should fit in those predetermined constraints. But as a project goes along, budgets and deadlines find a way to get tighter than you planned.

But innovative designs and interactions can seem especially scary for clients to approve. There’s three fears that often pop up on projects:

The fear of change. 

Maybe the client expected something simple, a light refresh. Something that doesn’t challenge their design expectations or require more time and effort to understand. And on our side, maybe we didn’t sufficiently ease them into our way of thinking and open them up to why we think something bigger and bolder is the right solution for them. Baby steps, y’all.

The fear of the unknown. 

Or, less dramatically, a lack of understanding of the medium. In the past, we have struggled with how to present an interactive, animated design to a client before it’s actually built. Looking at a site that does something conceptually similar as an example can be tough. It’s asking a lot of a client’s imagination to show them a site about boots that has a cool spinning animation and get meaningful feedback about how a spinning animation would work on their site about after-school tutoring. Or maybe we’ve created static designs, then talked around what we envision happening. Again, what seems so clear in our minds as professionals entrenched in this stuff every day can be tough for someone outside the tech world to clearly understand.

The fear of losing control. 

We’re all about learning from past mistakes. So lets say, after dealing with that fear of the unknown on a project, next time you go in the opposite direction. You invest time up front creating something polished. Maybe you even get the developer to build a prototype that moves and looks like the real thing. You’ve taken all the vague mystery out of the process, so a client will be thrilled, right? Surprise, probably not! Most clients are working with you because they want to conquer the noble quest that is their redesign together. When we jump straight to showing something that looks polished, even if it’s not really, it can feel like we jumped ahead without keeping them involved. Like we took away their input. They can also feel demotivated to give good, meaningful feedback on a polished prototype because it looks “done.”

So what to do? Lately we have found low-fidelity prototypes to be a great tool for combating these fears and better communicating our ideas.

What are low-fidelity prototypes?

Low fidelity prototypes are a tool that designers can create quickly to illustrate an idea, without sinking time into making it pixel-perfect. Some recent examples of prototypes we've created include a clickable Figma or Invision prototype put together with Whimsical wireframes:

A rough animation created in Principle illustrating less programatic animation:

And even creating an animated storyboard in Photoshop:

They’re rough enough that there’s no way they could be confused for a final product. But customized so that a client can immediately understand what they’re looking at and what they need to respond to. Low-fidelity prototypes hit a sweet spot that addresses those client fears head on.

That fear of change? A lo-fi prototype starts rough and small, so it can ease a client into a dramatic change without overwhelming them. It’s just a first step. It gives them time to react and warm up to something that’ll ultimately be a big change.

It also cuts out the fear of the unknown. Seeing something moving around, even if it’s rough, can be so much more clear than talking ourselves in circles about how we think it will move, and hoping the client can imagine it. The feature is no longer an enigma cloaked in mystery and big talk, but something tangible they can point at and ask concrete questions about.

And finally, a lo-fi prototype doesn’t threaten a client’s sense of control. Low-fidelity means it’s clearly still a work in progress! It’s just an early step in the creative process, and therefore communicates that we’re still in the middle of that process together. There’s still plenty of room for their ideas and feedback.

Lo-fi prototypes: client-tested, internal team-approved

There are a lot of reasons to love lo-fi prototypes internally, too!

They’re quick and easy. 

We can whip up multiple ideas within a few hours, without sinking the time into getting our hearts set on any one thing. In an agency setting especially, time is limited, so the faster we can get an idea out of our own heads, the better.

They’re great to share with developers. 

Ideally, the whole team is working together simultaneously, collaborating every step of the way. Realistically, a developer often doesn’t have time during a project’s early design phase. Lo-fi prototypes are concrete enough that a developer can quickly tell if building an idea will be within scope. It helps us catch impractical ideas early and helps us all collaborate to create something that’s both cool and feasible.

Stay tuned for posts in the near future diving into some of our favorite processes for creating lo-fi prototypes!

I get into this situation sometimes. Maybe you do too. I merge feature work into a branch used to collect features, and then continue development but on that branch instead of back on the feature branch

and have to move those commits to the feature branch they belong in and take them out of the throwaway accumulator branch

Maybe you prefer

over

Either way, that works. But it'd be nicer if we didn't have to type or even remember the branches' names and the remote's name. They are what is keeping this from being a context-independent string of commands you run any time this mistake happens. That's what we're going to solve here.

Shorthands for longevity

I like to use all possible natively supported shorthands. There are two broad motivations for that.

1. Fingers have a limited number of movements in them. Save as many as possible left late in life.
2. Current research suggests that multitasking has detrimental effects on memory. Development tends to be very heavy on multitasking. Maybe relieving some of the pressure on quick-access short term memory (like knowing all relevant branch names) add up to leave a healthier memory down the line.

First up for our scenario: the - shorthand, which refers to the previously checked out branch. There are a few places we can't use it, but it helps a lot:

We cannot use - when cherry-picking a range

and even if we could we'd still have provide the remote's name (here, origin).

That shorthand doesn't apply in the later reset --hard command, and we cannot use it in the branch -D && checkout approach either. branch -D does not support the - shorthand and once the branch is deleted checkout can't reach it with -:

So we have to remember the remote's name (we know it's origin because we are devoting memory space to knowing that this isn't one of those times it's something else), the remote tracking branch's name, the local branch's name, and we're typing those all out. No good! Let's figure out some shorthands.

@{-<n>} is hard to say but easy to fall in love with

We can do a little better by using @{-<n>} (you'll also sometimes see it referred to be the older @{-N}). It is a special construct for referring to the nth previously checked out ref.

Back in our scenario, we're on qa-environment, we switch to feature, and then want to refer to qa-environment. That's @{-1}! So instead of

We can do

Here's where we are (🎉 marks wins from -, 💥 marks the win from @{-1})

One down, two to go: we're still relying on memory for the remote's name and the remote branch's name and we're still typing both out in full. Can we replace those with generic shorthands?

@{-1} is the ref itself, not the ref's name, we can't do

because there is no branch origin/@{-1}. For the same reason, @{-1} does not give us a generalized shorthand for the scenario's later git reset --hard origin/qa-environment command.

But good news!

Do @{u} @{push}

@{upstream} or its shorthand @{u} is the remote branch a that would be pulled from if git pull were run. @{push} is the remote branch that would be pushed to if git push was run.

we can

Tacking either onto a branch name will give that branch's @{upstream} or @{push}. For example

is the branch branch-a pulls from.

In the common workflow where a branch pulls from and pushes to the same branch, @{upstream} and @{push} will be the same, leaving @{u} as preferable for its terseness. @{push} shines in triangular workflows where you pull from one remote and push to another (see the external links below).

Going back to our scenario, it means short, portable commands with a minimum human memory footprint. (🎉 marks wins from -, 💥 marks the win from @{-1}, 😎 marks the wins from @{u}.)

Make the things you repeat the easiest to do

Because these commands are generalized, we can run some series of them once, maybe

or

and then those will be in the shell history just waiting to be retrieved and run again the next time, whether with CtrlR incremental search or history substring searching bound to the up arrow or however your interactive shell is configured. Or make it an alias, or even better an abbreviation if your interactive shell supports them. Save the body wear and tear, give memory a break, and level up in Git.

And keep going

The GitHub blog has a good primer on triangular workflows and how they can polish your process of contributing to external projects.

The FreeBSD Wiki has a more in-depth article on triangular workflow process (though it doesn't know about @{push} and @{upstream}).

The construct @{-<n>} and the suffixes @{push} and @{upstream} are all part of the gitrevisions spec. Direct links to each:

• @{-<n>}
  

• @{push}
  

• @{upstream}
  

Viget is full of outdoor enthusiasts and, of course, technologists. For this year's Pointless Weekend, we brought these passions together to build TrailBuddy. This app aims to solve that eternal question: Is my favorite trail dry so I can go hike/run/ride?

While getting muddy might rekindle fond childhood memories for some, exposing your gear to the elements isn’t great – it’s bad for your equipment and can cause long-term, and potentially expensive, damage to the trail.

There are some trail apps out there but we wanted one that would focus on current conditions. Currently, our favorites trail apps, like mtbproject.com, trailrunproject.com, and hikingproject.com -- all owned by REI, rely on user-reported conditions. While this can be effective, the reports are frequently unreliable, as condition reports can become outdated in just a few days.

Our goal was to solve this problem by building an app that brought together location, soil type, and weather history data to create on-demand condition predictions for any trail in the US.

We built an initial version of TrailBuddy by tapping into several readily-available APIs, then running the combined data through a machine learning algorithm. (Oh, and also by bringing together a bunch of smart and motivated people and combining them with pizza and some of the magic that is our Pointless Weekends. We'll share the other Pointless Project, Scurry, with you soon.)

The quest for data.

We knew from the start this app would require data from a number of sources. As previously mentioned, we used REI’s APIs (i.e. https://www.hikingproject.com/data) as the source for basic trail information. We used the trails’ latitude and longitude coordinates as well as its elevation to query weather and soil type. We also found data points such as a trail’s total distance to be relevant to our app users and decided to include that on the front-end, too. Since we wanted to go beyond relying solely on user-reported metrics, which is how REI’s current MTB project works, we came up with a list of factors that could affect the trail for that day.

First on that list was weather.

We not only considered the impacts of the current forecast, but we also looked at the previous day’s forecast. For example, it’s safe to assume that if it’s currently raining or had been raining over the last several days, it would likely lead to muddy and unfavorable conditions for that trail. We utilized the DarkSky API (https://darksky.net/dev) to get the weather forecasts for that day, as well as the records for previous days. This included expected information, like temperature and precipitation chance. It also included some interesting data points that we realized may be factors, like precipitation intensity, cloud cover, and UV index. 

But weather alone can’t predict how muddy or dry a trail will be. To determine that for sure, we also wanted to use soil data to help predict how well a trail’s unique soil composition recovers after precipitation. Similar amounts of rain on trails of very different soil types could lead to vastly different trail conditions. A more clay-based soil would hold water much longer, and therefore be much more unfavorable, than loamy soil. Finding a reliable source for soil type and soil drainage proved incredibly difficult. After many hours, we finally found a source through the USDA that we could use. As a side note—the USDA keeps track of lots of data points on soil information that’s actually pretty interesting! We can’t say we’re soil experts but, we felt like we got pretty close.

Putting our design hats on.

From the very first pitch for this app, TrailBuddy’s main differentiator to peer trail resources is its ability to surface real-time information, reliably, and simply. For as complicated as the technology needed to collect and interpret information, the front-end app design needed to be clean and unencumbered.

We thought about how users would naturally look for information when setting out to find a trail and what factors they’d think about when doing so. We posed questions like:

• How easy or difficult of a trail are they looking for?
• How long is this trail?
• What does the trail look like?
• How far away is the trail in relation to my location?
• For what activity am I needing a trail for?
• Is this a trail I’d want to come back to in the future?

By putting ourselves in our users’ shoes we quickly identified key features TrailBuddy needed to have to be relevant and useful. First, we needed filtering, so users could filter between difficulty and distance to narrow down their results to fit the activity level. Next, we needed a way to look up trails by activity type—mountain biking, hiking, and running are all types of activities REI’s MTB API tracks already so those made sense as a starting point. And lastly, we needed a way for the app to find trails based on your location; or at the very least the ability to find a trail within a certain distance of your current location.

Using machine learning to predict trail conditions.

As stated earlier, none of us are actual soil or data scientists. So, in order to achieve the real-time conditions reporting TrailBuddy promised, we’d decided to leverage machine learning to make predictions for us. Digging into the utility of machine learning was a first for all of us on this team. Luckily, there was an excellent tutorial that laid out the basics of building an ML model in Python. Provided a CSV file with inputs in the left columns, and the desired output on the right, the script we generated was able to test out multiple different model strategies, and output the effectiveness of each in predicting results, shown below.

We assembled all of the historical weather and soil data we could find for a given latitude/longitude coordinate, compiled a 1000 * 100 sized CSV, ran it through the Python evaluator, and found that the CART and SVM models consistently outranked the others in terms of predicting trail status. In other words, we found a working model for which to run our data through and get (hopefully) reliable predictions from. The next step was to figure out which data fields were actually critical in predicting the trail status. The more we could refine our data set, the faster and smarter our predictive model could become.

We pulled in some Ruby code to take the original (and quite massive) CSV, and output smaller versions to test with. Now again, we’re no data scientists here but, we were able to cull out a good majority of the data and still get a model that performed at 95% accuracy.

With our trained model in hand, we could serialize that to into a model.pkl file (pkl stands for “pickle”, as in we’ve “pickled” the model), move that file into our Rails app along with it a python script to deserialize it, pass in a dynamic set of data, and generate real-time predictions. At the end of the day, our model has a propensity to predict fantastic trail conditions (about 99% of the time in fact…). Just one of those optimistic machine learning models we guess.

Where we go from here.

It was clear that after two days, our team still wanted to do more. As a first refinement, we’d love to work more with our data set and ML model. Something that was quite surprising during the weekend was that we found we could remove all but two days worth of weather data, and all of the soil data we worked so hard to dig up, and still hit 95% accuracy. Which … doesn’t make a ton of sense. Perhaps the data we chose to predict trail conditions just isn’t a great empirical predictor of trail status. While these are questions too big to solve in just a single weekend, we'd love to spend more time digging into this in a future iteration.

Viget Explorations have always been the result of our shared curiosities. They’re usually a spontaneous outcome of team downtime and a shared problem we’ve experienced. We use our Explorations to pursue our diverse interests and contribute to the conversations about building a better digital world.

As the COVID-19 crisis emerged, we were certainly experiencing a shared problem. As a way to keep busy and manage our anxieties, a small team came together to dive into how technology has helped, and, unfortunately, hindered the community response to the current pandemic.

We started by researching the challenges we saw: information overload, a lack of clarity, individual responsibility, and change. Then we brainstormed possible technical solutions that could further improve how communities respond to a pandemic. Click here to see our Exploration on some possible ways to take the panic out of pandemics.

While we aren’t currently pursuing the solutions outlined in the Exploration, we’d love to hear what you think about these approaches, as well as any ideas you have for how technology can help address the outlined challenges.

Please note, this Exploration doesn’t provide medical information. Visit the Center for Disease Control’s website for current information and COVID-19, its symptoms, and treatments.

At Viget, we’re adjusting to this crisis for the safety of our clients, our staff, and our communities. If you’d like to hear from Viget's co-founder, Brian Williams, you can read his article on our response to the situation.

Working on website front ends I sometimes use MAMP PRO to manage local hosts and Sequel Pro to manage databases. Living primarily in my text editor, a terminal, and a browser window, moving to these click-heavy dedicated apps can feel clunky. Happily, the tasks I have most frequently turned to those apps for —starting and stopping servers, creating new hosts, and importing, exporting, deleting, and creating databases— can be done from the command line.

I still pull up MAMP PRO if I need to change a host's PHP version or work with its other more specialized settings, or Sequel Pro to quickly inspect a database, but for the most part I can stay on the keyboard and in my terminal. Here's how:

Command Line MAMP PRO

You can start and stop MAMP PRO's servers from the command line. You can even do this when the MAMP PRO desktop app isn't open.

Note: MAMP PRO's menu icon will not change color to reflect the running/stopped status when the status is changed via the command line.

• Start the MAMP PRO servers:

• Stop the MAMP PRO servers:

• Create a host (replace host_name and root_path):

MAMP PRO-friendly Command Line Sequel Pro

Note: if you don't use MAMP PRO, just replace the /Applications/MAMP/Library/bin/mysql with mysql.

In all of the following commands, replace username with your user name (locally this is likely root) and database_name with your database name. The -p (password) flag with no argument will trigger an interactive password prompt. This is more secure than including your password in the command itself (like -pYourPasswordHere). Of course, if you're using the default password root is not particular secure to begin with so you might just do -pYourPasswordHere.

Setting the -h (host) flag to localhost or 127.0.0.1 tells mysql to look at what's on localhost. With the MAMP PRO servers running, that will be the MAMP PRO databases.

• Create a local database

or

    MAMP PRO's databases are stored in /Library/Application Support/appsolute/MAMP PRO/db so to confirm that it worked you can

• Delete a local database

• Export a dump of a local database. Note that this uses mysqldump not mysql.

• Export a local dump from an external database over SSH. Note that this uses mysqldump not mysql.

• Import a local database dump into a local database

• Import a local database dump into a remote database over SSH. Use care with this one. But if you are doing it with Sequel Pro —maybe you are copying a Craft site's database from a production server to a QA server— you might as well be able to do it on the command line.

For me, using the command line instead of the MAMP PRO and Sequel Pro GUI means less switching between keyboard and mouse, less opening up GUI features that aren't typically visible on my screen, and generally better DX. Give it a try! And while MAMP Pro's CLI is limited to the essentials, command line mysql of course knows no limits. If there's something else you use Sequel Pro for, you may be able to come up with a mysql CLI equivalent you like even better.

Viget has helped organizations design and develop award-winning websites and digital products for 20 years. In that time, we’ve been lucky to create long-term relationships with clients like Puma, the World Wildlife Fund, and Privia Health, and, throughout our time working together, we’ve come to understand each others’ unique terminology. But that isn’t always the case when we begin work with new clients, and in a constantly-evolving industry, we know that new terminology appears almost daily and organizations have unique definitions for deliverables and processes.

Kicking off a project always initiates a flurry of activity. There are contracts to sign, team members to introduce, and new platforms to learn. It’s an exciting time, and we know clients are anxious to get underway. Amidst all the activity, though, there is a need to define and create a shared lexicon to ensure both teams understand the project deliverables and process that will take us from kickoff to launch.

Below, we’ve rounded up a few terms for each of our disciplines that often require additional explanation. Note: our definitions of these terms may differ slightly from the industry standard, but highlight our interpretation and use of them on a daily basis.

User Experience

Research

In UX, there is a proliferation of terms that are often used interchangeably and mean almost-but-subtly-not the same thing. Viget uses the term research to specifically mean user research — learning more about the users of our products, particularly how they think and behave — in order to make stronger recommendations and better designs. This can be accomplished through different methodologies, depending on the needs of the project, and can include moderated usability testing, stakeholder interviews, audience research, surveys, and more. Learn more about the subtleties of UX research vocabulary in our post on “Speaking the Same Language About Research”.

Wireframes

We use wireframes to show the priority and organization of content on the screen, to give a sense of what elements will get a stronger visual treatment, and to detail how users will get to other parts of the site. Wireframes are a key component of website design — think of them as the skeleton or blueprint of a page — but we know that clients often feel uninspired after reviewing pages built with gray boxes. In fact, we’ve even written about how to improve wireframe presentations. We remind clients that visual designers will step in later to add polish through color, graphics, and typography, but agreeing on the foundation of the page is an important and necessary first step.

Prototypes

During the design process, it’s helpful for us to show clients how certain pieces of functionality or animations will work once the site is developed. We can mimic interactivity or test a technical proof of concept by using a clickable prototype, relying on tools like Figma, Invision, or Principle. Our prototypes can be used to illustrate a concept to internal stakeholders, but shouldn’t be seen as a final approach. Often, these concepts will require additional work to prepare them for developer handoff, which means that prototypes quickly become outdated. Read more about how and when we use prototypes.

Navigation Testing (Treejack Testing)

Following an information architecture presentation, we will sometimes recommend that clients conduct navigation testing. When testing, we present a participant with the proposed navigation and ask them to perform specific tasks in order to see if they will be able to locate the information specified within the site’s new organization. These tests generally focus on two aspects of the navigation: the structure of the navigation system itself, and the language used within the system. Treejack is an online navigation testing tool that we like to employ when conducting navigation tests, so we’ll often interchange the terms “navigation testing” with “treejack testing”.

Learn more about Viget’s approach to user experience and research. 

In my last post, I defined terms used by our UX team that are often confused or have multiple meanings across the industry. Today, I’ll share our definitions for processes and deliverables used by our design and strategy teams.

Creative

Brand Strategy

In our experience, we’ve found that the term brand strategy is used to cover a myriad of processes, documents, and deliverables. To us, a brand strategy defines how an organization communicates who they are, what they do and why in a clear and compelling way. Over the years, we’ve developed an approach to brand strategy work that emphasizes rigorous research, hands-on collaboration, and the definition of problems and goals. We work with clients to align on a brand strategy concept and, depending on the client and their goals, our final deliverables can range to include strategy definition, audience-specific messaging, identity details, brand elements, applications, and more. Take a look at the brand strategy work we’ve done for Fiscalnote, Swiftdine, and Armstrong Tire.

Content Strategy

A content strategy goes far beyond the words on a website or in an app. A strong content strategy dictates the substance, structure, and governance of the information an organization uses to communicate to its audience. It guides creating, organizing, and maintaining content so that companies can communicate who they are, what they do, and why efficiently and effectively. We’ve worked with organizations like the Washington Speakers Bureau, The Nature Conservancy, the NFL Players Association, and the Wildlife Conservation Society to refine and enhance their content strategies.

Still confused about the difference between brand and content strategy? Check out our flowchart.

Style Guide vs. Brand Guidelines

We often find the depth or fidelity of brand guidelines and style guides can vary greatly, and the terms can often be confused. When we create brand guidelines, they tend to be large documents that include in-depth recommendations about how a company should communicate their brand. Sections like “promise”, “vision”, “mission”, “values”, “tone”, etc. accompany details about how the brand’s logo, colors and fonts should be used in a variety of scenarios. Style guides, on the other hand, are typically pared down documents that contain specific guidance for organizations’ logos, colors and fonts, and don’t always include usage examples.

Design System

One question we get from clients often during a redesign or rebrand is, “How can I make sure people across my organization are adhering to our new designs?” This is where a design system comes into play. Design systems can range from the basic — e.g., a systematic approach to creating shared components for a single website — all the way to the complex —e.g., architecting a cross-product design system that can scale to accommodate hundreds of different products within a company. By assembling elements like color, typography, imagery, messaging, voice and tone, and interaction patterns in a central repository, organizations are able to scale products and marketing confidently and efficiently. When a design system is translated into code, we refer to that as a parts kit, which helps enforce consistency and improve workflow.

Comps or Mocks

When reviewing RFPs or going through the nitty-gritty of contracts with clients, we often see the terms mocks or comps used interchangeably to refer to the static design of pages or screens. Internally, we think of a mock-up as a static image file that illustrates proof-of-concept, just a step beyond a wireframe. A comp represents a design that is “high fidelity” and closer to what the final website will look like, though importantly, is not an exact replica. This is likely what clients will share with internal stakeholders to get approval on the website direction and what our front-end developers will use to begin building-out the site (in other words, converting the static design files into dynamic HTML, CSS, and JavaScript code).

If you're interested in joining our team of creative thinkers and visual storytellers who bring these concepts to life for our clients, we’re hiring in Washington, D.C. Durham, Boulder and Chattanooga. Tune in next week as we decipher the terms we use most often when talking about development.

Video conference tools are an indispensable part of the Plague Times. Google Meet, Microsoft Teams, Zoom, and their compatriots are keeping us close and connected in a physically distanced world.

As tech-savvy folks with years of cross-office collaboration, we’ve laughed at the sketches and memes about vidconf mishaps. We practice good Zoomiquette, including muting ourselves when we’re not talking.

Yet even we can’t escape one vidconf pitfall. (There but for the grace of Zoom go I.) On nearly every vidconf, someone starts to talk, and then someone else says: “Oop, you’re muted.” And, inevitably: “Oop, you’re still muted.”

That’s right: we’re trying to follow Zoomiquette by muting, but then we forget or struggle to unmute when we do want to talk.

In this post, I’ll share my theories for why the You’re Muted Problems are so pervasive, using Google Meet, Microsoft Teams, and Zoom as examples. Spoiler alert: While I hope this will help you be more mindful of the problem, I can’t offer a good solution. It still happens to me. All. The. Time.

Skip the why and go straight to the vidconf app keyboard shortcuts you should memorize right now.

Why we don't realize we’re muted before talking

Why does this keep happening?!?

Simply put: UX and design decisions make it harder to remember that you’re muted before you start to talk.

Here’s a common scenario: You haven’t talked for a bit, so you haven’t interacted with the Zoom screen for a few seconds. Then you start to talk — and that’s when someone tells you, “You’re muted.”

We forget so easily in these scenarios because when our mouse has been idle for a few seconds, the apps hide or downplay the UI elements that tell us we’re muted.

Zoom and Teams are the worst offenders:

• Zoom hides both the toolbar with the main in-app controls (the big mute button) and the mute status indicator on your video pane thumbnail.
• Teams hides the toolbar, and doesn't show a mute status indicator on your video thumbnail in the first place.

Meet is only slightly better:

• Meet hides the toolbar, and shows only a small mute status icon in your video thumbnail.

Even when our mouse is active, the apps’ subtle approach to muted state UI can make it easy to forget that we’re muted:

Teams is the worst offender:

• The mute button is an icon rather than words.
• The muted-state icon's styling could be confused with unmuted state: Teams does not follow the common pattern of using red to denote muted state.
• The mute button is not differentiated in visual hierarchy from all the other controls.
• As mentioned above, Teams never shows a secondary mute status indicator.

Zoom is a bit better, but still makes it pretty easy to forget that you’re muted:

• Pros:
  • Zoom is the only app to use words on the mute button, in this case to denote the button action (rather than the muted state).
  • The muted-state icon’s styling (red line) is less likely to be confused with the unmuted-state icon.
• Cons:
  • The mute button’s placement (bottom left corner of the page) is easy to overlook.
  • The mute button is not differentiated in visual hierarchy from the other toolbar buttons — and Zoom has a lot of toolbar buttons, especially when logged in as host.
  • The secondary mute status indicator is a small icon.
  • The mute button’s muted-state icon is styled slightly differently from the secondary mute status indicator.
• Potential Cons:
  • While words denote the button action, only an icon denotes the muted state.

Meet is probably the clearest of the three apps, but still has pitfalls:

• Pros:
  • The mute button is visually prominent in the UI: It’s clearly differentiated in the visual hierarchy relative to other controls (styled as a primary button); is a large button; and is placed closer to the center of the controls bar.
  • The muted-state icon’s styling (red fill) is less likely to be confused with the unmuted-state icon.
• Cons:
  • Uses only an icon rather than words to denote the muted state.
• Unrelated Con:
  • While the mute button is visually prominent, it’s also placed next to the hang-up button. So in Meet’s active state you might be less likely to forget you’re muted … but more likely to accidentally hang up when trying to unmute. 😬
    

I know modern app design leans toward minimalism. There’s often good rationale to use icons rather than words, or to de-emphasize controls and indicators when not in use.

But again: This happens on basically every call! Often multiple times per call!! And we’re supposed to be tech-savvy!!! Imagine what it’s like for the tens of millions of vidconf newbs.

I would argue that “knowing your muted state” has turned out to be a major vidconf user need. At this point, it’s certainly worth rethinking UX patterns for.

Why we keep unsuccessfully unmuting once we realize we’re muted

So we can blame the You’re Muted Problem on UX and design. But what causes the You’re Still Muted Problem? Once we know we’re muted, why do we sometimes fail to unmute before talking again?

This one is more complicated — and definitely more speculative. To start making sense of this scenario, here’s the sequence I’m guessing most commonly plays out (I did this a couple times before I became aware of it):

The crucial part is when the person tries to unmute by pressing the keyboard Volume On/Off key.

If that’s in fact what’s happening (again, this is just a hypothesis), I’m guessing they did that because when someone says “You’re muted” or “I can’t hear you,” our subconscious thought process is: “Oh, Audio is Off. Press the keyboard key that I usually press when I want to change Audio Off to Audio On.”

There are two traps in this reflexive thought process:

First, the keyboard volume keys control the speaker volume, not the microphone volume. (More specifically, they control the system sound output settings, rather than the system sound input settings or the vidconf app’s sound input settings.)

In fact, there isn’t a keyboard key to control the microphone volume. You can’t unmute your mic via a dedicated keyboard key, the way that you can turn the speaker volume on/off via a keyboard key while watching a movie or listening to music.

Second, I think we reflexively press the keyboard key anyway because our mental model of the keyboard audio keys is just: Audio. Not microphone vs. speaker.

This fuzzy mental model makes sense: There’s only one set of keyboard keys related to audio, so why would I think to distinguish between microphone and speaker? 

So my best guess is hardware design causes the You’re Still Muted Problem. After all, keyboard designs are from a pre-Zoom era, when the average person rarely used the computer’s microphone.

If that is the cause, one potential solution is for hardware manufacturers to start including dedicated keys to control microphone volume:

Video conference keyboard shortcuts you should memorize right now

Let me know if you have other theories for the You’re Still Muted Problem!

In the meantime, the best alternative is to learn all of the vidconf app keyboard shortcuts for muting/unmuting:

• Meet
  • Mac: Command(⌘) + D
  • Windows: Control + D
• Teams
  • Mac: Command(⌘) + Shift + M
  • Windows: Ctrl + Shift + M
• Zoom
  • Mac: Command(⌘) + Shift + A
  • Windows: Alt + A
  • Hold Spacebar: Temporarily unmute

Other vidconf apps not included in my analysis:

• Cisco Webex Meetings
  • Mac: Ctrl + Alt + M
  • Windows: Ctrl + Shift + M
• GoToMeeting
  • Mac: No keyboard shortcut?
  • Windows: Ctrl + Alt + A

Bonus protip from Jackson Fox: If you use multiple vidconf apps, pick a keyboard shortcut that you like and manually change each app’s mute/unmute shortcut to that. Then you only have to remember one shortcut!

Viget is replete with literature enthusiasts. We have a book club, blog posts about said book club, and a #poetry channel on Slack for sharing Wendell Berry and Emily Dickinson. Before the pandemic it saw only occasional activity. That was until our Employee Engagement Manager, Aubrey Lear, popped up one day with a proposal: a month-long haiku challenge. (Hat tip to Nicole Gulotta for the excellent prompts.)

Haikus have long been beloved by Vigets. (In fact we have a #haiku channel too, but all the action tends to go down in #poetry.) There’s something about the form’s constraints, pithiness, and symmetry that appeals to us — a bunch of creatives, developers, and strategists who value elegant solutions. What we didn’t know was that a haiku-a-thon would also become a highlight of our very, very many Work From Home days.

For my part, writing haikus has become a charming distraction from worry. When I find my brain fidgeting over Covid-19 what-if scenarios, I set it a task. 5-7-5. Stack those syllables up, break ‘em down. How far can I push the confines of that structure? Where should the line breaks be? One run-on sentence? Find a punchline? It’s a nice little bit of syntactic Tetris. It stops me going down mental rabbit holes — a palette-cleansing exercise after a day’s bad news.

Then there’s the getting-to-know-you benefit that comes from Vigets sharing their daily haikus, each interpreting the prompts differently, offering a unique and condensed take on things common to us all.

There’s Elyse with her gorgeous personification of household objects:

Around the House

The small tea kettle

is now forming a union.

She demands more pay.

Or Laura, musing on the mundane things we miss:

Something you long for

strolling up and down

the aisles, browsing away

wonder everywhere

just taking my time

tossing products in my cart

ye olde target run

Josh’s odes are always a pick-me-up:

Nourishing Meal

O orange powder

On mac, Doritos, Cheetos

Finger-licking gewd.


While Grace’s are thoughtful and profound:

Thoughts while Driving

Tis human nature

We struggle to grasp the weight

Till it’s upon us


There’s Peyton, with his humorous wordplay:

Plant Friends

Plant friends everywhere

Watch them grow from far away

Then come back to them

Plant friends everywhere

Water them with Zooms and calls

They’ll water you too


And Claire, who grounds us in reality:

While folding laundry

gym shorts and sports bras

mostly what I’m folding now

goodbye skirts and jeans

Kate is sparky:

Lighting a candle

lighter fluid thrills

fingertips quiver, recoil

fire takes hold within

While I find the whole thing cathartic:

Breath

Old friend — with me since

birth — whom I seldom take time

to appreciate.

Our first #30daysfohaikuchallenge is over now, so we’ve decided to start another. Won’t you join us? Prompts are below and you can share your haiku in the comments.

Though I usually enjoy working from Viget’s lovely Boulder office, during quarantine I am now working from home while simultaneously parenting my 3-year-old daughter Audrey. My husband works in healthcare and though he is not on the front lines battling COVID-19, he is still an essential worker and as such leaves our home to work every day.

Some working/parenting days are great! I somehow get my tasks accomplished, my kid is happy, and we spend some quality time together.

And some days are awful. I have to ignore my daughter having a meltdown and try to focus on meetings, and I wish I wasn’t in this situation at all. Most days are somewhere in the middle; I’m just doing my best to get by.

I’ve seen enough working parent memes and cries for help on social media to know that I’m not alone. There are many parents out there who now get to experience the stress and anxiety of living through a global pandemic while simultaneously navigating ways to stay productive while working from home and being an effective parent. Fun isn’t it?

I’m not an expert on the matter, but I have found a few small things that are making me feel a bit more sane. I hope sharing them will make someone else’s life easier too.

Truths to Accept

First, let’s acknowledge some truths about this new situation we find ourselves in:

Truth 1: We’ve lost something.

Parents have lost more than daycare and schools during this epidemic. We’ve lost any time that we had for ourselves, and that was really valuable. We no longer have small moments in the day to catch up on our personal lives. I no longer have a commute to separate my work duties from my mom duties, or catch up with my friends, or just be quiet.

Truth 2: We’re human.

The reason you can’t be a great employee and a great parent and a great friend and a great partner or spouse all day every day isn’t because you’re doing a bad job, it’s because being constantly wonderful in all aspects of your life is impossible. Pick one or two of those things a day to focus on.

Truth 3: We’re all doing our best.

This is the most important part of this article. Be kind to yourselves. This isn’t easy, and putting so much pressure on yourself that you break isn’t going to make it any easier.

Work from Home Goals

Now that we’ve accepted some truths about our current situation, let’s set some goals.

Goal 1: Do Good Work

At Viget, and wherever you work, with kids or without we all want to make sure that the quality of our work stays up throughout the pandemic and that we can continue to be reliable team members and employees to the best of our abilities.

Goal 2: Stay Sane

We need to figure out ways to do this without sacrificing ourselves entirely. For me, this means fitting my work into normal work hours as much as possible so that I can still have some downtime in the evenings.

Goal 3: Make This Sustainable

None of us knows how long this will last but we may as well begin mentally preparing for a long haul.

Work from Home Rules

Now, there are some great Work from Home Rules that apply to everyone with or without kids. My coworker Paul Koch shared these with the Viget team a Jeremy Bearimy ago and I agree this is also the foundation for working from home with kids.

1. When you’re in a remote meeting, minimize other windows to stay focused
2. Set a schedule and avoid chores*
3. Take breaks away from the screen
4. Plan your workday on the calendar+
5. Be mindful of Slack and social media as a distraction
6. Use timers+
7. Keep your work area separate from where you relax
8. Pretend that you’re still WFW
9. Experiment and figure out what works for you

In the improv spirit I say “Yes, AND….” to these tips. And so, here are my adjusted rules for WFH while kiddos around: These have both been really solid tools for me, so let’s dig in.

Day Planning: Calendars and Timers

A few small tweaks and adjustments make this even more doable for me and my 3-year-old. First- I don’t avoid chores entirely. If I’m going up and down the stairs all day anyway I might as well throw in a load of laundry while I’m at it. The more I can get done during the day means a greater chance of some down time in the evening.

Each morning I plan my day and Audrey’s day:

When we make the schedule together it also helps me understand her favorite parts of the day and reminds me to include them.

Once our days are planned, I also use timers to help keep the structure of the day. (I bought a great alarm clock for kids on Amazon that turns colors to signal bedtime and quiet time. It’s been hugely worth it for me.)

Work from Home Rules: Updated for Parents

Finally, I have a few more Work from Home Rules for parents to add to the list:

1. Minimize other windows in remote meetings
2. Set a schedule and fit in some chores if time allows
3. Take breaks away from the screen
4. Schedule both your and your kids’ days
5. Be mindful of Slack and social media as a distraction
6. Use timers to track your own time and help your kids understand the day
7. Keep your work area separate from where you relax
8. Pretend that you’re still WFW
9. Experiment and figure out what works for you
10. Be prepared with a few activities
    • Each morning, have just ONE thing ready to go. This can be a worksheet you printed out, a coloring station setup, a new bag of kinetic sand you just got delivered from Amazon, a kids dance video on YouTube or an iPad game. Recently I started enlisting my mom to read stories on Facetime. The activity doesn’t have to be new each day but (especially for young kids) it has to be handy for you to start up quickly if your schedule changes
11. Clearly communicate your availability with your team and project PMs
    • Life happens. Some days are going to be hard. Whatever you do, don’t burn yourself out or leave your team hanging. If you need to move a meeting or take a day off, communicate that as early and as clearly as you can.
12. Take PTO if you can
    • None of us are superheroes. If you’re feeling overwhelmed- take a look at the next few days and figure out which one makes the most sense for you to take a break.
13. Take breaks to be alone without doing a task
    • Work and family responsibilities have blended together, there’s almost no room for being alone. If you can find some precious alone time don’t use it to fold laundry or clean the bathroom. Just zone out. I think we all really need this.

Last but not least, enjoy your time at home if you can. This is an unusual circumstance and even though it’s really hard, there are parts that are really great too.

If you have some great WFH tips we’d love to hear about them in the comments!

So you’ve just written a blog post or tweet about why wireframes are becoming obsolete, the dangers of “too accessible” design, or how a certain style of icon creates “cognitive fatigue.”

Your post went viral, but now you’re getting ratioed by rude people on the Internet. That sucks! You were just trying to start a conversation and you probably didn’t deserve all that negativity (except for you, “too accessible” guy).

Most likely, you made one of these common mistakes:

1. You made generalizations about “design”

You, a good user-centered designer, know that you are not your user. Nor are you every designer.

First of all, let's acknowledge that there is no universal definition of design. Even if we narrow it down to software design, it’s still hard to make generalizations. Agency, in-house, product, startup, enterprise, non-profit, website, app, connected hardware, etc. – there are a lot of different work contexts and cultures for people with “designer” in their titles.

"The Design Industry" is not a thing, but even if it were, you don't speak for it. Don’t assume that the kind of design work you do is the universal default.

2. You didn’t share enough context

There are many great design books and few great design blog posts. (There are, to my knowledge, no great design tweets, but I am open to your suggestions.) Writing about design is not well suited to short formats, because context plays such an important role and there’s always a lot of it to cover.

Writing about your work should include as much context as you would include if you were presenting your portfolio for a job interview. What kind of organization did you work for? Who was your client and/or your stakeholders? What was the goal of the project? Your timeline? What was the makeup of your team? What were the notable business rules and constraints? How are you defining effectiveness and success?

Without these kinds of details, it’s not possible for other designers to know if what you’ve written is credible or applicable to them.

3. You were too certain

A blog post doesn’t need to be a dissertation. It’s okay to share hunches and anecdotes, but give the necessary caveats. And if you're making claims about science, bruh, you gotta cite your sources.

Be humble in your takes. Your account of what worked for you and why is more valuable to your peers than making sweeping claims and reheating the same old arguments. Be prepared to be told you’re wrong, and have the humility to realize that your perspective is just your perspective. Real conversations, like good design, are built on feedback and diverse viewpoints.

—

Together, we can improve the discourse in our information ecosystems. Don't generalize. Give context. Be humble.

During the winter 2020 Pointless Weekend, we built TrailBuddy (working app coming soon). Our team consisted of four developers, two project managers, two front-end developers, a digital-analyst, a UXer, and a designer. In about 48 hours, we took an idea from Jeremy Field’s head to a (mostly) working app. We broke up the project in two parts:. First, a back-end that crunches trail, weather, and soil data. That data is exposed via a GraphQL API for a web app to consume.

While developers built the API, I built a static front end using Next.js. Famously, static front-ends don’t have a database, or a concept of “users.” A bit of functionality I wanted to add was saving favorite trails. I didn’t want to be hacky about it, I needed some way to add users and a database. I knew it’d be hard for the developers to set this up as part of the API, they had their hands full with all the #soil-soil-soil-soil-soil (a slack channel dedicated solely to figuring out our soil data problem—those were plentiful.) I had been looking for an excuse to use Userbase, and this seemed like as good a time as any.

A textbook Userbase use case

“When would I use it?” The Usebase site lists these reasons:

• If you want to build a web app without writing any backend code.
• If you never want to see your users' data.
• If you're tired of dealing with databases.
• If you want to radically simplify your GDPR compliance.
• And if you want to keep things really simple.

This was a perfect fit for my problem. I didn’t want to write any more backend code for this. I didn’t want to see our user’s data, I don’t care to know anyone’s favorite trails.* A nice bonus to not having users in our backend was not having to worry about keeping their data safe. We don’t have their data at all, it’s end-to-end encrypted by Userbase. We can offer a reasonable amount of privacy for free (well for the price of using Userbase: $49 a year.) I am not tired of dealing with databases, but I’d rather not. I don’t think anyone doesn’t want to simplify their GDPR compliance. Finally, given our tight timeline I wanted nothing more than to keep things really simple.

Using Userbase

Userbase can be tried for free, so I set aside thirty minutes or so to do a quick proof of concept to make sure this would work out for us. I made an account and followed their Quickstart. Userbase is a fundamentally easy tool to use, but their quickstart is everything I’d want out of a quickstart:

• Written in the most vanilla way possible (just HTML and vanilla JS). This means I can adapt it to my needs, in this case React using Next.js
• Easy to follow, it does the most barebones tour of the functionality you can expect to get out of the SDK (software development kit.) In other words it is quick and it is a start
• It has a live demo and code samples you can download and run yourself

It didn’t take long after that to integrate Userbase into our app with more help from their great docs. I debated whether to add code samples of what we did here, and I didn’t because any reader would be better off using the great quickstart and docs Userbase provides—they are that clear, and that good. Depending on your use case you’ll need to adapt the examples to your needs, for us the trickiest things were creating a top level authentication context to manage users in the app, and a custom hook to encapsulate all the logic for setting, updating, and deleting favourite trails in the app. Userbase’s SDK worked seamlessly for us.

Is Userbase for you?

Maybe. I am definitely a fan, so much so that this blog post probably reads like an advert. Userbase saved me a ton of time in this project. It reminded me of “The All Powerful Front End Developer” talk by Chris Coyer. I don’t fully subscribe to all the ideas in that talk, but it is nice to have “serverless” tools like Userbase, and all the new JAMstacky things. There are limits to the Userbase serverless experience in terms of scale, and control. Obviously relying on a third party for something always carries some (probably small) risk—it’s worth noting Usebase includes a note on their pricing page that says “You can host it yourself always under your control, or we can run it for you for a full serverless experience”—Still, I wouldn’t hesitate this to use in future projects.

One of the great things about Viget and Pointless Weekend is the opportunity to try new things. For me that was Next.js and Userbase for Trailbuddy. It doesn’t always work out (in fact this is my first pointless weekend where a risk hasn’t blown up in my face) but it is always fun. Getting to try out Userbase and beginning to think about how we may use it in the future made the weekend worthwhile for me, and it made my job on this project much more enjoyable.

*I will write a future post about privacy conscious analytics in TrailBuddy when I’ve figured that out. I am looking into Fathom Analytics for that.

Setting it up

First, here's the config setup you need to even allow for such a radical concept.

1. Define the global gitignore file as a global Git configuration:

   git config --global core.excludesfile ~/.gitignore
   

   If you're on OSX, this command will add the following config lines in your ~/.gitconfig file.

   [core]
     excludesfile = /Users/triplegirldad/.gitignore
   

2. Load that ~/.gitignore file up with whatever you want. It probably doesn't exist as a file yet so you might have to create it first.

Harnessing its incredible power

There are only two lines in my global gitignore file and they are both fairly useful pretty much all the time.

$ cat ~/.gitignore
TODO.md
playground

This 2 line file means that no matter where I am, what project I'm working on, where in the project I'm doing so, I have an easy space to stash notes, thoughts, in progress ideas, spikes, etc.

TODO.md

More often than not, I'm fiddling around with a TODO.md file. Something about writing markdown in your familiar text editor speaks to my soul. It's quick, it's easy, you have all the text editing tricks available to you, and it never does anything you wouldn't expect (looking at you auto-markdown-formatting editors). I use one or two # for headings, I use nested lists, and I ask for nothing more. Nothing more than more TODO.md files that is!

In practice I tend to just have one TODO.md file per project, right at the top, ready to pull up in a few keystrokes. Which I do often. I pull this doc up if:

• I'm in a meeting and I just said "oh yeah that's a small thing, I'll knock it out this afternoon".
• I'm halfway through some feature development and realize I want to make a sweeping refactor elsewhere. Toss some thoughts in the doc, and then get back to the task at hand.
• It's the end of the day and I have to switch my brain into "feed small children" mode, thus obliterating everything work-related from my short term memory. When I open things up the next day and know exactly what the next thing to dive into was.
• I'm preparing for a big enough refactor and I can't hold it all in my brain at once. What I'd give to have an interactive 3D playground for brain thoughts, but in the meantime a 2D text file isn't a terrible way to plan out dev work.

playground

Sometimes you need more than some human words in a markdown file to move an idea along. This is where my playground directory comes in. I can load this directory up with code that's related to a given project and keep it out of the git history. Because who doesn't like a place to play around.

I find that this directory is more useful for long running maintenance projects over fast moving greenfield ones. On the maintenance projects, I tend to find myself assembling a pile of scripts and experiments for various situations:

• The client requests a one-time obscure data export. Whip up some CSV generation code and save that code in the playground directory.
• The client requests a different obscure data export. Pull up the last time you did something vaguely similar and save yourself the startup time.
• A batch of data needs to be imported just once. Might as well stash that in the chance that "just once" is actually "just a few times".
• Kicking the tires on an integration with a third party service.

Some of these playground files end up being useful more times than I can count (eg: the ever-changing user_export.rb script). Some items get promoted into application code, which is always fun. But most files here serve their purpose and then wither away. And that's fine. It's a playground, anything goes.

Wrapping up

Having a personal space for project-specific notes and code has been helpful to me over the years as a developer on multiple projects. If you have your own organizational trick, or just want to brag about how you memorize everything without any markdown files, let me know in the comments below!
