Stackoverflow Is A Difficult Community to Participate In
These are a few of the reasons why I have difficulty in participating in the StackOverflow community. I was once a very active user, but due to these reasons, and a few unstated, I am unable to participate in the community anymore. The Eternal September Issue. Many new users of StackOverflow...

APIs for Manufacturing
Perhaps you too remember that crayon-factory segment from Sesame Street. The one where they show dramatic shots of hot orange wax getting poured into vats and molds and eventually labeled and boxed up into neat packages of the rainbow, while Skrillex-junior music played in the background. This was my favorite segment…

Get Disciplined, Not Motivated
There's a lot of problems with simple motivation: Motivation is fleeting Motivation comes and goes however it wants. It might not last to the end of the week, end of the day, or even the end of blog post you just read. It's fleeting. Motivation is situational Motivation is based…

The Linux Graphics Stack
This is an introductory overview post for the Linux Graphics Stack, and how it currently all fits together. I initially wrote it for myself after having conversations with people like Owen Taylor, Ray Strode and Adam Jackson about this stack. I had to go back to them every month or so and learn the stuff from the…

Lord Camden on NSA Surveillance
I’m doing a deep dive into the pre-history of the Fourth Amendment, and am continuously amazed at how perfectly the condemnations of the “general warrants” that incensed the Framers apply to the programmatic authority granted the NSA under the FISA Amendments Act. The legal challenge to that statute is currently hung…

What I learned from my first C coding challenge
Last week at Vimeo we had a challenge. Build a better query string parameter sorter for a Varnish plugin. The gauntlet was thrown down at 5pm on a Friday and by 2am Friday night we had our first contender. I arrived home to see the code and decided to throw my hat into the ring. I had made some attempts at c plugins…

Why Tarsnap doesn't use Glacier
On the surface, Tarsnap sounds like the perfect use case for Glacier. Out of every TB of data stored on Tarsnap, in any given month approximately 100 GB of data will be deleted, while only 33 GB of data will be downloaded; in other words, Tarsnap is very much a "write once, read maybe " storage system. Tarsnap's…

The Laser Doodler
So I’ve got a project coming up (that may have something to do with this tweet ) that will require a few LED matrix displays. I found a suitable candidate online and ordered one to play around with. Since I already had the display, I thought it’d be fun to run it through the paces and build a little circuit out of it…

When you first begin to exercise, it’s somewhat painful. Not wildly painful, like touching a hot stove, but enough that if your only goal was to avoid pain, you certainly would stop doing it. But if you keep exercising… well, it just keeps getting more painful. When you’re done, if you’ve really pushed yourself, you…
