I like to build things and watch them work. Sometimes, they catch fire.
QT is an amazing framework, made all the more useful by having delightful Python bindings.

Mixins are classes which are not meant to be used by themselves but instead are meant to be combined with other mixins on top of a base class to extend the functionality of that class. They are a great way to modularize code and make class features compose-able. Mixins are best explained using a simple …

I was working on some C++ code, much like the one in this screen shot, when once again my IDE told me about some issue it had found with the code. The messages appear milli-seconds after I type some code in convenient tooltips placed in context. The messages are succinct, precise and usually contain enough information …
