There are no sacred technologies
In my previous post I talked about how there are no silver bullets, that is there are no technologies that will solve all your problems without introducing some of their own. In this post I will talk about something that happens often, as development processes mature in an organization, somehow technologies become sacred. Let’s startContinue reading “There are no sacred technologies”
There are no silver bullets!
It has been a long time since I posted something, but these are strange times. With the pandemic winding down and some light at the end of the tunnel, I finally have time to write some lines again. I thought about writing a long post, but then I decided to divide this post into twoContinue reading “There are no silver bullets!”
Typical use cases for Kafka
In my previous post I explained the main components of a Kafka system. In this post I will explain some of the typical use cases where Kafka is used. By typical I do not mean that all systems built on top of Kafka follow these patterns, only that these use cases are wildly used. BeforeContinue reading “Typical use cases for Kafka”

If you are from my generation or older, you remember the wonderful days of manually configuring hardware by using jumpers and then connecting the hardware to the ISA bus on a computer. Before I got my first PC, I owned a more user friendly system(an Atari 65XE), so new hardware was magically configured. Well theContinue reading “What you need to know about interrupts”

This post is an introductory post for people that would like to know more about device drivers and hardware programming. Therefore some simplifications have been made.

User to hardware (part 1)
This is the first post in a two post series covering the trip from a running process all the way down to the hardware and back. In this post I will cover the software side, this means I will start from a running process and walk through the different pieces that are needed to talkContinue reading “User to hardware (part 1)”
The so called userspace
Most people have heard the term userspace and most people have a grasp of what it means, but why is it called userspace and what is it? To understand the name we need to go back to the core and look at the architecture of a CPU. Most processors, including most microcontrollers, have two modesContinue reading “The so called userspace”

Many people have heard about the C Library and for most its name inspire awe and a magic aura. In short, the C Library is the library that implements the runtime for the C programming language. The C Library also provides an interface to manage the interaction between a process and the system. This isContinue reading “What you need to know about the C Library”
