Most strings found on the Internet are encoded using a particular unicode format called UTF-8. However, not all strings of bytes are valid UTF-8. The rules as to what constitute a valid UTF-8 string are somewhat arcane. Yet it seems important to quickly validate these strings before you consume them. In a previous…

This article was prompted by responses to a tweet I wrote in response to an analysis of the research area of papers submitted to the 2022 ICSE conference, the flagship conference for software engineering research. These led me to reflect on software engineering research in general. I’m sorry to say that I think that…
Cause a series of sequential operations to appear instantaneous or simultaneous.
What I write about my own personal journey is intended as just that—my personal journey.
A few weeks ago I got to make some of my code 1000 times faster, without changing the underlying complexity! As the title implies, this involved making Java reflection calls faster.
I have too many git branches and like many people I developed a convoluted script to show me the most recent ones. I ran this command many times a day for years:
In this post I'm going to talk about a small Haskell implementation I wrote which would have been much more difficult to write in other lang...
If you look at the programming languages benchmarks game, Python is one of the slowest commonly used programming languages out there . Typical programs written in pure Python average around 40 times slower than the equivalent program written in C or C++.
A light hearted look back at my time programming in the 1990s as I try to get an old Minesweeper implementation of mine from 1999, written in C++ using PowerPlant for Mac OS 8, compiling in Xcode 8 and running on macOS Sierra.
When coding style survives compilation: de-anonymizing programmers from executable binaries Caliskan et al., NDSS’18 As a programmer you have a unique style, and stylometry techniques can be used t…
This is not a tutorial. If you're looking for a quick, easy, "how to use git" kind of post, look elsewhere.The goal of this post is to give you just enough understanding of the git internals that you can build up a correct intuition of what various git commands actually do under the hood.
In this post you will learn what hash tables are, why you would use them, and how they are used to implement dictionaries in the most popular Python interpreter—CPython.
Scottish train operator ScotRail released a two-hour long MP3 file containing all of the components of its automated station announcements. Messing around with them is proving to be a huge …
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.
We used to use software; now software started to use us
In this post I’ll share my experience of building and using one of the earliest versions of the GNU C Compiler — GCC 1.27 (released in 1988) on a modern system.
