Dependency Inversion Principle (SOLID Part 5)
Part of my SOLID programming principles series.
What is the Dependency Inversion Principle?
The Dependency Inversion Principle can be summed up in one simple quote “design for the interface, not the implementation”. The idea is that software is built by making simple objects and functions, which are then used by more complex objects and functions. This principle is a way to make it...

In Reponse to Moving away from writing on Tumblr
in reponse to adamjmorgan and geeksathome :
I definitely plan on still using Tumblr in some regard, probably having blog posts I write show up here, either as a link or as full text. There’s also a lot of content that I think wouldn’t make sense for a full-on blog post, but would make sense as a tumblr post.

New Temporary Homepage →
I’ve been busy, but I’ve been meaning to update my homepage for a long time. Finally had time to fix some server issues and at least get a temporary one up. Hopefully after finals I can have a more full-fledged site up.

What do you wish school would have taught you...
You can learn a lot from computer science programs at schools, but I feel like a lot of programs leave students ill-prepared for the real world. What are some topics or skills you wish were covered at your school that were not?

Great article by Paul Graham
I’ve heard this put another way that helps a lot of people understand: Creative work is a lot like sleep. It takes time to get into REM, the really deep, most restful form of sleep. If you wake someone up in the middle of REM asleep, when they go back to sleep they don’t go back to REM, they have to start the whole process over again.
