December Picks

November was a slow month since I was on vacation, but I managed to pick up some good stuff. Take a look!

The Myth of the Root Cause

I learned a lot from this post, and the paper it refers to: “How Complex Systems Fail”.

If you work with distributed systems and you ever had to write a post-mortem this is a must read. The post explains common false assumptions when looking for a root cause of an incident, in other words:

12 Signs You’re Working in a Feature Factory

The Cyber Swiss Army Knife

A simple, intuitive web app for analysing and decoding data without having to deal with complex tools or programming languages. CyberChef encourages both technical and non-technical people to explore data formats, encryption and compression.

Simple Units Conversions

If you ever had to convert an unit to another (e.g. seconds to hours), there is a tool available on OSX and Linux by default: It’s units!

→ units
586 units, 56 prefixes
You have: 600 seconds
You want: minutes
  * 10
  / 0.1
You have: 100 kilometers/hour
You want: miles/hour
  * 62.137119
  / 0.01609344

Helps when you don’t have internet to Google it 😬

To improve as a software engineer you want to learn how to do your work in less time, which is important if you want to take on bigger, harder projects.
