Akka and Kotlin coroutines: ♡

I've experimented with Kotlin and coroutines in programming Akka. And I must say, I really like the combination so far.
But before I go into it some brief preliminaries for those who don't know Akka and actors.

Actors and Akka

Actors are a programming model that fits cloud native architectures particularly well. Being highly available and scaling horizontally. All while embracing the realities of multiple servers collaborating, server instances coming and going and the network having hickups.

On the JVM Akka is the prominent actor framework. It's been around for a while now and as a result it's highly reliable, well thought out and offers a wide programming eco system. My own interest in Akka is because of its suitability for software systems that can only be built with business events as a key construct and thinking model. And then of course materialized views, CQRS and near real-time data streams play a big role in constructing those systems.

Summary of book "Clean Architecture" by Robert C. Martin

Uncle Bob, the well known author of Clean Code, is coming back to us with a new book called Clean Architecture which wants to take a larger view on how to create software.

Even if Clean Code is one of the major book around OOP and code design (mainly by presenting the SOLID principles), I was not totally impressed by the book.

Clean Architecture leaves me with the same feeling, even if it's pushing the development world to do better, has some good stories and present robust principles to build software.

The book is build around 34 chapters organised in chapters.

How to recover lost Python source code if it's still resident in-memory

I screwed up using git ("git checkout --" on the wrong file) and managed to delete the code I had just written... but it was still running in a process in a docker container. Here's how I got it back, using https://pypi.python.org/pypi/pyrasite/ and https://pypi.python.org/pypi/uncompyle6

Attach a shell to the docker container

Install GDB (needed by pyrasite)

apt-get update && apt-get install gdb

If you have a certificate that is not
trusted by Android, when you add it, it goes in the personal cert store.
When you add a cert in this personal cert store, the system requires a
higher security level to unlock the device. But if you manage to add your
cert to the system store then you don't have this requirement. Obviously,
root is required to add a certificate to the system store, but it is quiet
easy.
