How statically linked programs run on Linux
In this article I want to explore what happens when a statically linked program gets executed on Linux.

In reality, most programs one encounters on Linux aren't statically linked, and do require one or…

Software Development Estimates: Where Do I Start?
For some reason many people discuss the problem of estimating software development timeframes without properly understanding the issue. There is a famous answer on Quora that exemplifies this.

Maven is broken by design
The other day, someone asked about the status of the GWT Mavenization, saying he loves Maven and would like to help. I replied that “I used to really like it” but wasn't “so sure nowadays.” It obviously was followed by “I know it could cause issues if not used in the proper way […] Do you mind telling me why you don't…

Light Table a year ago
A year ago today I put up the original blog post for Light Table . It was just a simple video of a prototype I made in less than a week while I was visiting my grandparents without internet - at the time we had no idea what it would become.

I'm going to post about them soon, but first I thought it would be cool to give some background about what a memory allocator actually does. So, if you've ever wondered what happens when you…

Advanced Vim Registers
Registers in Vim are best thought of as scratch spaces for text, some of which are automatically filled by the editor in response to certain actions. Learning how to use registers fluently has a lot of subtle benefits, although it takes some getting used to because the syntax for using them is a little awkward.

I’ve been meaning to write up my take on the learn to code movement for quite some time now, but for one reason or another haven’t managed to get around to it. Now that the president is endorsing Computer Science and telling Americans to learn to code, this post has jumped to the top of my priority list.

The Go 1.1 scheduler
One of the big features for Go 1.1 is the new scheduler, contributed by Dmitry Vyukov. The new scheduler has given a dramatic increase in performance for parallel Go programs and with nothing better to do, I figured I'd write something about it.
