SE Radio 563: David Cramer on Error Tracking

In this episode, David Cramer, co-founder and CTO of Sentry, joins host Jeremy Jung for a conversation about error tracking. The discussion starts with treating performance problems as errors, why you might not need logs, and how most applications share the same problems. From there they consider other topics including capturing information by hooking into runtimes and frameworks, issues with the quality of Open Telemetry data, how front-end applications are constantly changing and why that makes them hard to instrument. Finally, they discuss how Sentry's architecture has evolved, and why they switched from a permissive license to the Business Source License.

SE Radio 578: Ori Mankali on Secrets Management using Distributed Fragments Cryptography

In this episode, Ori Mankali, senior VP of engineering at cloud security startup Akeyless, speaks with SE Radio’s Nikhil Krishna about secrets management and the innovative use of distributed fragment cryptography (DFC). In the context of enterprise IT, 'secrets’ are crucial for authentication in providing access to internal applications and services. Ori describes the unique challenges of managing these sensitive data, particularly given the complexities of doing so on a large scale in substantial organizations. They discuss the necessity for a secure system for managing secrets, highlighting key features such as access policies, audit capabilities, and visualization tools. Ori introduces the concept of distributed fragment cryptography, which boosts security by ensuring that the entire secret is never known to any single entity. The episode explores encryption and decryption and the importance of key rotation, as they consider the challenges and potential solutions in secrets management.

RSS Enclosure Support in Micro.Blog

An effort is underway to examine how feed publishers and feed consumers are handling the lack of clarity in the RSS 2.0 specification about whether an item can contain more than one enclosure. The RSS Best Practices Profile recommends that a feed item should contain no more than one enclosure "for best support in the widest number of aggregators," advice worth testing against current usage.

The artisanal small-batch blogging service Micro.blog is a platform for sharing short posts like Twitter, but in a way designed to be less viral, more low key and less prone to provocation, attention seeking and clout chasing. There are no follower counts, public likes or trending topics. Founder Manton Reese explained why in his book Indie Microblogging:

Big social networks like Instagram are designed to amplify accounts that gain traction, whether they are fake or not.

Micro.blog limits search and avoids public likes and reposts so that the snowball starts small and stays small. Instead of going viral and becoming a major problem, fake accounts can be spotted early and shut down if necessary.

Since being funded by a Kickstarter campaign in 2017 that hit its goal in one day, Micro.blog has attracted a dedicated following. One of the options available to premium subscribers is to host a podcast. An audio button appears below the post editing window to choose a media file.

Choosing a podcast file to add to a post

Micro.blog sites have a primary RSS feed and a separate podcast feed. The latter contains enclosure elements. Because the Micro.blog editing window does not allow more than one podcast to be added to a post, the RSS item for a post contains only one enclosure:

Celebrate Creativity

I have to begin this post by apologizing for not realizing January was "International Creativity Month," but it should never be too late to celebrate creativity, should it?

The intent of International Creativity Month (founded by motivational speaker and author Randall Munson) is to remind people and organizations to capitalize on the power of creativity. My personal belief is that we are all creative in our own ways, but we might feel our creativity isn't wanted whether at school or work and we kind of "lose" our creative ability.

I believe we should encourage creativity with students, educators, and across all levels of employment. As Dictionary. com states:

Creativity is the ability to transcend traditional ideas, rules, patterns, relationships, or the like, and to create meaningful new ideas, forms, methods, interpretations, etc.; originality, progressiveness, or imagination: the need for creativity in modern industry; creativity in the performing arts.
So why wouldn't we want to champion the creativity within individuals? Without creativity, as individuals, we become stagnant in our thoughts and development as do our products and services within a business setting.

In a belated celebration of International Creativity Month, I wanted to offer some resources for creativity:

The Link: International Creativity Month: found on ipl2 – news and information, this resource highlights Randall Munson's newsletter and  illustrates how creativity is implemented in workplaces, in education, with food, with children, and across cultures.

The Center for Creative Learning: this site believes that people of all ages can improve their skills and ability to use creative and critical thinking, problem solving, and decision making, and that research on learning style helps us to understand how people develop and use their talents in unique and personal ways. They offer free resources, i.e newsletter, journal article reprints, sample activities, and ideas on assessing creativity (Assessing Creativity: A Guide for Educators and Assessing Creativity Index: a database of creativity tests and inventories)

Center for Excellence in Learning and Teaching: Created by Iowa State University, this site includes links to online resources, techniques for creative teaching, and evaluating creativity, etc.

The Torrance Center, University of Georgia: this site provides PowerPoint presentations, podcast lectures, activities and resources on creativity.

Sir Ken Robinson: Do Schools Kill Creativity?:  This presentation is the most highly viewed TED talk of all time. Robinson argues that we've been educated to become good workers, rather than creative thinkers. Students with restless minds and bodies -- far from being cultivated for their energy and curiosity -- are ignored or even stigmatized, with terrible consequences. "We are educating people out of their creativity," Robinson says.

Is Creativity Innate or Can it be Learned?: This post found on the CareerTech Testing Center blog highlights a study released by Adobe entitled, Creativity and Education: Why It Matters.

The Phenomenons Called Curiosity and Creativity: Another post found on the CareerTech Testing Center blog highlights the concepts of curiosity and creativity.
