[M] Petz0r and other wasp'ers, we can now dfu via pc, instead of android:
"Hi!

Some people may prefer a desktop solution for OTA DFUing micropython.zip. I found that https://github.com/dingari/ota-dfu-python works well for this:
sudo $HOME/ota-dfu-python/dfu.py -z $HOME/wasp-os/micropython.zip -a D6:62:01:XX:XX:XX
You may want to update your docu accordingly.

Untangling Microservices, or Balancing Complexity in Distributed Systems

The microservices-honeymoon period is over. Uber are refactoring thousands of microservices into a more manageable solution [1], according to Kelsey Hightower monoliths are the future [2], and even Sam Newman says that microservices should never be the default choice, but rather a last resort [3].

What is going on here? Why so many projects became unmaintainable, despite the microservices’ promise of simplicity and flexibility? Or maybe monoliths are better, after all? In this post, I want to address these questions. You will learn about common design issues that turn microservices into distributed big balls of mud, and of course, and how you can avoid them.
