I was lucky enough to grow up through the early 2000’s, during the golden age of Half-Life mods. Industry classics like Counter-Strike (CS) had just been invented, every month brought new mods to try, and files were too big to download on a dial-up connection so you’d leech them off a server at a big local LAN party…
April 30, 2024. I decided to dedicate a week to migrate our main project at work (a multiplayer mobile game server in production for over 4 years) from Scala...
“lex and yacc” are two terms that are used together so often that they can seem indivisible. lex takes a string as input and divides it up into lexemes (roughly speaking “words”) and yacc takes a sequence of lexemes and parses them. Since some parsing approaches such as recursive descent parsing unify these phases…
One of my favorite languages is the Go language. I love its simplicity. It is popular and useful in a cloud setting. Many popular tools are written in Go, and for good reasons. I gave a talk on Go last year and I was asked for a criticism of Go. I do not mind that … Continue reading The Go compiler needs to be smarter
This is an additional post in the “Go is not good” series. Go does have some nice features, hence the “The Good” part in this post, but overall I find it cumbersome and painful to use when we go beyond API or network servers (which is what it was designed ...
My manager and I got off on a tangent in our most recent one-on-one on the subject of the durability of design mistakes in programming languages. A particular favourite of mine is the worst of the …

WebFonts are awesome and here to stay. However, if used improperly, they can also impose a huge performance penalty. In this post, I explain how Rubygems.org painted 10x faster just by making a few...
In the interests of creating employment opportunities in the Java programming field, I am passing on these tips from the masters on how to write code that is so difficult to maintain, that the people who come after you will take years to make even the simplest changes. Further, if you follow all these rules…
If you just need bash, why do you need codemode?
The barrier to entry for building software has collapsed. The barrier to building something that matters hasn’t moved an inch.
Hacking on PostgreSQL is really hard. I think a lot of people would agree with this statement, not all for the same reasons. Some might poin...
A little rest area by the road to a better web.
In the old days when I started programming, green programmers trying to build their skills and get experience started out doing maintenance programming. Only the old hands got to write new code. The newbies cut their teeth debugging and fixing musty old code that still worked for the business. I’ve done my share of…
A webserver and reverse proxy solution brought to you by linuxserver.io with php support and a built-in Certbot client.
Trying out the Rust programming ecosystem as a 10+ years Python developer. How to do common programming tasks and how the tooling looks like.
You know what’s universally regarded as un-fun by most programmers? Writing assembly language code. As Steve McConnell said back in 1994: Programmers working with high-level languages achieve better productivity and quality than those working with lower-level languages. Languages such as C++, Java, Smalltalk, and…
Multiprocessor Synchronization was one of my favorite classes during my undergrad — it had a clear progression from theory to practice, starting at the theory of consensus numbers and moving onto atomic operations and then synchronization primitives and lock-free data structures, all from first principles. With…
Mike Kohn's music, software, and electronics projects.
This week’s paper won the distinguished presentation award at HotOS 2021, and discusses the potential for future innovation in the tool that many use every day - the shell! A previous submission of this paper on Hacker News elicited a number of strong reactions. One reaction was the assertion that there are in fact…

It all started with a routine task. I use GitHub issues for all of my public-facing projects but my preference is keeping track of things in Org Agenda. To reconcile the two, I would manually...
The Debian Janitor is an automated system that commits fixes for (minor) issues in Debian packages that can be fixed by software. It gradually started proposing merges in early December. The first set of changes sent out ran lintian-brush on sid packages maintained in Git. This post is part of a series about the…
There are some books which make you feel smarter just by having them on your shelf. This is one of them! I would consider it essential for anyone working with code - whether a wide-eyed newbie or grizzled veteran. How do human brains understand code? What neurological quirks do we all have? Which common mistakes can…
