Pub/Sub

practice-time

2 * 1 hour

The publish-subscribe architecture-pattern is very popular to route messages, according to WikiPedia. It is used much more generic, however. This workshop shows how to use it in an embedded application, or another single process application.
Then it becomes a HighTech (embedded) software design pattern.

We start with a simple implementation of Pub/Sub. You can experiment with that (Python) code and/or port it to your favorite language. Then, you are asked to design a cached, distributed version. Which is a bit more ambitious. And even though the result is probably pointless, it’s a great Design-Exercise and a lot of fun!

It will help you to understand Pub/Sub, help you to use it in embedded software. Eventually, you may need Pub/Sub in a distributed environment. Then, it is better to use one of the existing ones, like DDS (Data Distribution Service); which more efficient and even RealTime!
But, by knowing how to implement it and are able to design it, will help you to use it for the better

ThreadPoolExecutor

practice-time

2 * 1 hour

This workshop is about the ThreadPoolExecutor (‘TPE’ for friends): a pool of workers implemented with Threads. This is a modern, advanced design-pattern available in many languages.

You will get an introduction to the concepts, to be able to use the ‘TPE’. Also, we study Python implementation, to practice design-analyse.

De Embedded Linux Expert bestaat niet

reading-time

4 minuten

Regelmatig krijg ik ‘Embedded Linux Experts’ aangeboden; bijvoorbeeld voor het HTLD-team (HighTech Linux Delivery). Vaak zijn goede mensen, met Linux ervaring; maar toch niet de mensen die ik zoek. Het blijkt erg lastig voor niet direct betrokken, om de juiste experts te spotten. Daarom een paar hints waarmee je “de” Embedded Linux Expert herkent. Immers, alleen het woordje ‘Linux’ op een CV is onvoldoende!
