CSS in JS is a popular pattern, especially in the React and React Native communities. In CSS in JS in real-life, Artur Siery explores pros and cons of CSS Modules, SASS/LESS, Style Components, Glamorous, Styletron, Styled JSX, and JSS. If you want to deep-dive into how styled-components works, Eugene Gluhotorenko goes into great detail on that as well. This is a bad pattern and a return to inline styles. Mixing presentation and logic never works out well, and generating a bunch of unique utility classes doesn't make for sustainable design implementation, and leads developers to violate all kinds of DRY principals.

Some Clojure projects are giving out “liveness advisories”. Jeremy Pinnix pointed out one instance where no changes have been made in over 3 years. The project’s author assures that there just happen to be no changes needed, and the project is indeed alive and well. Some software projects don’t want to go on the cart.

Patrik Krupar talked through how he built up his design chops. Patrik advises, “Design is a skill, and like any other skill, it can be learned.” Checkout the guide, where he covers software, tools inside of that software, mentality differences, and some basic design tenets. Also on the design front, Jason Rodriguez preaches that the easiest way to keep your web apps accessible is to just use text. He’s right, and that post is a great read.

Electron Fiddle brings Electron a playground experience like JSFiddle for desktop apps. The article by Felix Rieseberg goes into details on its features, including a fantastic IDE-like experience powered by Monaco and the ability to easily build, export, and share your projects.

Mark de Jong explains Scala Sagas from first principles. In general, Sagas are useful for quasi-transactionally composing actions that can potentially fail (in this example, talking to disparate API endpoints) into a single unit, and providing compensating actions in the event of failure.

Google announced the stable release of Dart 2. Dart 2 features a sound type system, flexible tooling, a web framework, and an updated inference type system that minimizes boilerplate. The Dart team touts it’s much compile size and use for building consistent UXs, and includes over prebuilt UX components for use. Dart is aiming to be a real competitor in the web and mobile app building space (via Flutter), and this is an update worth looking into.

Eric Homes was able to gain commit access to Homebrew in 30 minutes. He details the process he went through for the exploit, now that it’s been mitigated. tl;dr - Homebrew intentionally exposes their Jenkins publicly, and Jenkins contained a GitHub API token that had commit privileges to a few homebrew repositories. We published a story recently on keeping your secrets hidden that covers (almost) this exact issue.

Yiming Chen details how to do outside-in TDD with Phoenix. Even if you aren’t a Phoenix developer, it’s a fantastic detailed walkthrough of the process of test-driving an app by writing feature tests first, then driving down into unit tests from there. The TDD strategy is: feature test; unit test controller action; unit test context functions; unit test view; a routing rule to pass the feature test.
