Lately at work most of the staff is puzzled with mysterious bug. In short there is a statemachine that processes movements in batches. But sometimes one particular movement is duplicated and nobody knows why...

I wish I could brag I solved it myself, but that is not the case. But it inspired me to dig a little bit in theory how distributed systems/concurrency is reasoned about and visualized.

Time space diagrams​

I have read about them in some book long ago and was looking for some time find the correct name. It's pretty niche concept, but in my opinon unjustly. They are so good to visualize not only distributed systems but also concurrency.

Let me show you.

Assembler was developed in 1947, wow! It makes 78 years of computing development in which we saw higher level programming languages, virtual machine programming languages (write once run everywhere), virtual machines, cloud and so on. A lot of knowledge got accumulated over the time which you can see in size of artifacts deployed to cloud.

Over the years we have seen several attempts reach for the roots. Similarly WebAssembly is instruction format for virtual machine designed to be portable compilation target for any language willing. It is fast as nearly native speed, secure and sandboxed and language agnostic. Originally wrote for the browsers it is beginning to get traction as microservice runtime, which btw is topic of this post.
