Server Reliability: The Rule of Nines

After a little, er, let’s call it discussion I had with a certain supplier recently, I decided to write down a few words on server reliability and how to measure and understand it. Like so many things that touch statistics it is very easy to take statements like “99.7% reliability” at face value without understanding its […]

A First Look at Swift: The Good, the Bad and the Ugly

This is a first look at Swift, Apple’s new programming language for MacOS and iOS development, which is still in Beta and thus by the time you are reading this, some of the bugs or features discussed here may have changed. Also, while I have worked with a couple of programming languages over the years, […]

Unicode Character Map

Here’s another project I’m working on: The Unicode Character Map – a small but (hopefully) useful tool to view all available Unicode characters.
