I thought I understood Kotlin coroutines until I actually timed them 🤯

"Concurrent" ≠ faster
"Asynchronous" ≠ “concurrent"

Built experiments to see what's really happening. Results were surprising.

Last week, a mentee asked me to explain the differences between MVC, MVP, and MVVM. I searched for resources, but found many were too complex for beginners. So, I took it as an opportunity to write a clear, concise guide. I hope it helps aspiring Android engineers understand these important concepts! Read the article here:

Thanks a lot
@androidmakersfr
for having me, and everyone who attended my talk, Demystifying the Test Pyramid!
The slides 🛝 are available already on SpeakerDeck

Demystifying the Test Pyramid

Back in 2009, Mike Cohn in his "Succeeding with Agile" book, introduced the pyramid of tests. Since then, it has been criticised (mostly for being unsuitable for many real life situations), slightly updated, but its core concept is still seen in many articles. So what value can we get out of the test pyramid, and how can you adapt it to better fit with your use cases, workflows and setup. After explaining the original concept of the testing pyramid, we will discuss its pitfalls and caveats, then provide more depth and a new perspective on this tool while providing tips and guidelines that engineers can use to improve their test suites.
