BPF: The Forgotten Bytecode
Every once in a while I run into an obscure computer technology that is a hidden gem, which over the years has become mostly forgotten. This is exactly how I feel about the tcpdump tool and its kernel counterpart the packet filter interface.

Hotspot performance engineering fails
Developers often believe that software performance follows a Pareto distribution: 80% of the running time is spent in 20% of the code. Using this model, you can write most of your code without any care for performance and focus on the narrow pieces of code that are performance sensitive. Engineers like Casey Muratori…

CSS Architecture

If you're really good, you use the latest and greatest techniques like media queries, transitions and tra

My review of the C standard library in practice
In general, when working in C I avoid the standard library, libc, as much as possible. If possible I won’t even link it. For people not used to working and thinking this way, the typical response is confusion. Isn’t that like re-inventing the wheel? For me, libc is a wheel barely worth using — too many deficiencies in…

Trying out this Go thing at Disqus
Disqus has a history of using one tool for the job and hammering through everything. Until now, that tool has been Python. This mentality has been extremely beneficial for us since we are a small team. Everyone is able to jump in to any piece of our stack with minimal effort.
