On Freund, founder of Wilco and former VP of Engineering at WeWork, speaks with SE Radio’s Brijesh Ammanath about “upskilling” – going deeper or increasing the breadth of your skills. On has years of experience in helping developers master the skills needed to advance in their careers. This episode explores the importance of upskilling in a constantly evolving tech landscape. They focus particularly on how and why senior and expert developers should keep learning, upskilling, and reskilling throughout their careers. Freund offers suggestions on how to face some common challenges, especially for remote or distributed workers, and how and why engineering managers can help enable upskilling for their teams.

Paul Hammant, independent consultant, joins host Giovanni Asproni to speak about trunk-based development—a version control management practice in which developers merge small, frequent updates to a core “trunk” or main branch. The episode explores the technique in some detail, including its pros and cons and some examples from real projects, and offers suggestions on how to get started. The conversation touches on a set of related topics, including code reviews, feature flags, continuous integration, and testing.

In this episode, Varun Singh, Chief Products and Technology Officer at Daily.co, speaks with host Nikhil Krishna about the 30-year evolution of web protocols. In particular, they explore the impact of protocol ossification, which has supported the Internet’s success but also limits the flexibility of evolving protocol suites such as TCP/IP and UDP by constraining future development. Varun points out how the end-to-end principle emphasizes full flexibility for end hosts, but the TCP implementation in the OS kernel as well as in “middle boxes” such as ISPs contributes to the constraints of ossification by blocking certain types of traffic. Further, the development of new protocols is challenging due to the need for backward compatibility with existing protocols. They discuss Google’s efforts – and the challenges it has faced – in working to move the HTTP protocol forward. The role of standards bodies such as the IETF and collaboration between industry stakeholders is crucial for the evolution of internet protocols, requiring a balance between maintaining backward compatibility and introducing new protocols such as QUIC and HTTP/3 to address existing constraints and improve internet performance and security. indeed, QUIC includes features that seek to actively avoid ossification and encourage evolution.

Arun Gupta, Vice President and General Manager of Open Ecosystem Initiatives at Intel Corporation, discusses open-source strategy and community with SE Radio host Kanchan Shringi.

Nick Tune and Jean-Georges Perrin join host Giovanni Asproni to talk about their proposed approach to modernizing legacy systems. The episode starts with some high-level perspective to set context for the approach described in their book, Architecture Modernization (Manning, 2024). From there, the discussion turns to important details, including criteria for deciding which aspects to revisit; some of the activities, processes, and tools; and the importance of data engineering in modernization efforts. Nick and Jean-Georges describe how to successfully implement an architecture-modernization effort, and how to fit that work with the teams' other priorities. The episode finishes with some warnings about the typical risks associated with modernizing a legacy system, and suggestions on how to mitigate them.

Brent Simmons, the developer of the NetNewsWire RSS reader, is questioning his decision to put an unread count next to each feed, reasoning that it encourages people to be too obsessive about reading every item:

Instead of a dozen bookmarks, people had a hundred feeds. Or two hundred. Or two thousand.

And there was a tyranny behind keeping track of unread items and showing an unread count. People reacted in different ways, but many people felt like they always had to go through everything.

Including me. To this day.

I did not know this was going to happen. That was not the idea: it was a side effect of reasonable (at the time) choices.

I like seeing these counts on feeds where I need to read all items that are posted, but that's only a small percentage of the 100-120 feeds I follow. It would be nice to turn that off for others I read more casually.

Feedly presents unread counts on each feed and folder of feeds. There's a Mark As Read button to clear a count, but when you click it, the confirmation dialog acts like it's an extremely consequential decision: "Are you sure you want to mark this entire source as read? This operation cannot be undone."

I've posed a question on the RSS-Public mailing list: Do you think feed readers should count unread items?

If you publish an RSS feed, you should do a solid for the developers of RSS readers by including a guid in each item. The guid's job is to be a unique identifier that helps software downloading your feed decide whether it has seen that item before. Here's the guid for an item on the arts and technology blog Laughing Squid:

<guid isPermaLink="false">https://laughingsquid.com/?p=914660</guid>

No other item on Laughing Squid will ever have this guid value. It's a URL that loads a blog post with the title Playful Elephant Pretends to Eat Woman's Hat. If you load the guid's URL https://laughingsquid.com/?p=914660, it redirects to the permanent link of the post. Because the guid is not the permanent link, there's an isPermaLink attribute with a value of false.

Most guid values in RSS feeds are the permanent link of the item, as in this example from the world news site Semafor:

<guid>https://www.semafor.com/article/07/07/2023/us-jobs-data-what-experts-make-of-the-new-numbers</guid>

A drawback of using the permalink is that if any part of the URL changes -- such as the title text or the domain name -- the guid changes and RSS readers will think this is a new item to show the feed's subscribers, when it's actually a repeat.

A guid doesn't have to be a URL. It can be any string that the feed publisher has chosen to be unique. Here's the guid from the RSS Advisory Board's feed for this blog post:

<guid isPermaLink="false">tag:rssboard.org,2006:weblog.217</guid>

Our guid follows the TAG URI scheme, a simple way to assure uniqueness by putting these five components together in this order:

1. The text "tag"
2. A domain owned by the feed provider
3. A year the provider owned that domain
4. A short name for the feed different from any other feed on the site
5. The internal ID number of the post

There's different punctuation between each component. The year 2006 was when the board began using the domain rssboard.org. No one else used that domain that year, so any feed reader that stores "tag:rssboard.org,2006:weblog.217" as this item's guid should never encounter that value in any other item on any other feed.

To see how RSS 2.0 feeds are using guid, several thousand feeds were downloaded this evening from an RSS aggregator that publicly shares the OPML subscription lists of its users.

The term guid means "globally unique identifier," but RSS 2.0 does not require global uniqueness in guids. Because the TAG URI scheme does a good job of serving that purpose, Blogger, Flickr, MetaFilter, SoundCloud and The Register are among the sites using it in their feeds.
