Developer Interviews: On asking job candidates to code


Luckily ThoughtWorks had a process that was a bit different from the usual standards companies had back then. After a quick recruiter screening, they sent me three options of a code challenge, a small problem I could solve in any programming language I would like to use. My code submission would then be used during follow-up interviews, including a pairing session where a ThoughtWorker and I would try to extend my code adding a new feature.

Team building: "Meme-Your-Colleague"

Lately we were hiring a lot of developers and had to integrate them in our team. So we decided to do an infotainment team event, targeting both: getting to know each other on a personal level and learning about the business and technical state, challenges and visions. Usually a meeting like this starts with everybody telling a few words about themselves... one... after... each... other... and after third speaker latest everybody gets bored. So we came up with the "Meme-Your-Colleague" game: Build teams of two persons Give them half an hour to get to know each other Both have to assemble a five minute presentation of five slides of each other Each slide consists of exactly one meme telling a (fun) fact of that person You may want to use a meme generator  and a presentation tool like Keynote or PowerPoint. It ended up with the whole team having a lot of fun: a perfect ice breaker! Give it a shot!

Netflix Android and iOS Studio Apps — now powered by Kotlin Multiplatform

  The high likelihood of unreliable network connectivity led us to lean into mobile solutions for robust client side persistence and offline support. The need for fast product delivery led us to experiment with a multiplatform architecture. Now we’re taking this one step further by using Kotlin Multiplatform to write platform agnostic business logic once in Kotlin and compiling to a Kotlin library for Android and a native Universal Framework for iOS via Kotlin/Native.

threadingText - jQuery Plugin to enable HTML to allow thread text as known in Adobe Illustrator.

threadingText is a JavaScript jQuery plugin to enable thread text in HTML. With a responsive web design and dynamic content using thread text is hard to achieve; here is where threadingText comes into play. The jQuery plugin threadingText provides a nice way of dynamically associate and fill HTML in pre-defined text containers and cut overlapping text with a specified ending symbol (default is " ...") or create new text containers according to a specified prototype text container if text would exceed provided space. The implementation uses a binary text length search to divide the HTML among the text containers provided. While doing so it tries its best to repair any HTML tags beeing broken while threading the HTML in the text containers. Additionally many code hooks are provided, where you can interfere in the layouting process and adjust the results in any way. GitHub

Microservice Micro-Feature architecture for mobile Apps

RIBs is the cross-platform architecture framework behind many mobile apps at Uber. The name RIBs is short for Router, Interactor and Builder, which are core components of this architecture. This framework is designed for mobile apps with a large number of engineers and nested states. The RIBs architecture provides: Shared architecture across iOS and Android. Build cross-platform apps that have similar architecture, enabling iOS and Android teams to cross-review business logic code. Testability and Isolation. Classes must be easy to unit test and reason about in isolation. Individual RIB classes have distinct responsibilities like: routing, business, view logic, creation. Plus, most RIB logic is decoupled from child RIB logic. This makes RIB classes easy to test and reason about independently. Tooling for developer productivity. RIBs come with IDE tooling around code generation, memory leak detection, static analysis and runtime integrations - all which improve developer product...

Dark Theme (Dark Mode) in Android WebViews, WKWebViews and CSS

So your apps just implemented a shiny new dark theme and it’s looking 👌 There are lots of benefits to having a dark theme in your application, and having it consistent throughout your application allows for a great user experience. But what happens when the the user runs into a WebView in your app? Support: if (WebViewFeature.isFeatureSupported(WebViewFeature.FORCE_DARK)) { ... } Set: WebSettingsCompat.setForceDark(webView.settings, WebSettingsCompat.FORCE_DARK_ON) Current setting: val forceDarkMode = WebSettingsCompat.getForceDark(webView.settings) Joe Birch Assuming your question is asking how to change the colors of the HTML content you are displaying in a WKWebView based on whether light or dark mode is in effect, there is nothing you do in your app's code. All changes need to be in the CSS being used by your HTML content. CSS dark mode via :root variables, explicit colors and @media query: :root {     color-scheme: light dark;      ...
