Building a high performance JSON parser
JSON is important, damn near everything that we do as programmers or operators involves JSON at some point. JSON decoding is expensive, if your product talks JSON then performance of marshalling data in and out of JSON is important. This is a talk about designing an efficient replacement for encoding/json.Decoder .

On the Beauty of Python's ExitStack (2015)
I believe Python's ExitStack feature does not get the recognition it deserves. I think part of the reason for this is that its documentation is somewhere deep down in the (already obscure) contextlib module because formally ExitStack is just one of many available context managers for Python's with statement . But…

Text layout is a loose hierarchy of segmentation
I love text layout, and have been working with it in one form or other for over 35 years. Yet, knowledge about it is quite arcane. I don’t believe there is a single place where it’s all properly written down. I have some explanation for that: while basic text layout is very important for UI, games, and other contexts…

A gentle intro to assembly with Rust
One of the things I’ve wanted to do for a while is really dig into assembly and get into the weeds of how programs actually run. A rework of the asm macro has recently landed in nightly rust so it seemed like a good time.

Timeouts and cancellation for humans (2018)
Your code might be perfect and never fail, but unfortunately the outside world is less reliable. Sometimes, other people's programs crash or freeze. Networks go down; printers catch on fire . Your code needs to be prepared for this: every time you read from the network, attempt to acquire an inter-process lock, or…
