A friend of mine recently pointed me at a well hidden command line tool. In the JavaScript framework used by Safari and other parts of Apple’s products, there is a tool called jsc. It’s a command line interface for JavaScript that uses the same code as the rest of the system. You can find the […]
UNIX (well, POSIX) signals are probably one of the worst parts of the UNIX API, and that’s a relatively high bar. A signal can be sent to your program at any point when it’s running, and you have to deal with it somehow. Traditionally, there are three ways …
Implementing the execution functionality of the shell
I've been noticing more and more lately that we have a plethora of libraries and programs written for Go, which don't work on one platform o...

Lately, I’ve been playing around with inventing a visual writing system for lambda calculus.
If you work with Protocol Buffers (protobuf), you can really save time, boredom, and headache by parsing your defin…
Here’s a followup to last month’s post about Penrose Tiling in Obfuscated Python. The Mandelbrot set is a traditional favorite among authors of obfuscated code. You …
One rainy evening I meditated about memory managment in Java and how effectively Java collections utilise memory. I made simple experiment, how much entries can I insert into Java Map with 16 GB of RAM?
The soft maximum approximates the maximum function, and approaches it in the limit, but is easier to work with.
The most valueble code in my repo, is the code I didn't write.
I encounter this feeling frequently. I have a sudden need (or idea) and I realize that such and such a tool or service must already exist. As a software engineer, I’ve learned to not let that feeling pass. Usually, it’s a chance to learn something (because usually it does exist) and sometimes it’s a chance to to build…
As the story of C’s birth goes hand in hand with the creation of Unix, the first C compiler can be traced back to the early 1970’s.
How to use Nom to parse binary protocols at the level of individual bits
Over the past year I've been working on a minimal-dependency hobbyist computing stack (everything above the processor) called Mu . The goal is to:
In February I open-sourced a library called Specter , and in my own work it has become by far my m...
This post is part of a series, you can see an overview of the whole series in [ rust-typestate-index ].
The current article describes a series of Java Virtual Machine (JVM) benchmarks with a primary focus on top-tier Just-In-Time (JIT) compilers, such as C2 JIT, and Graal JIT. The benchmarks are structured in three distinct (artificial) categories:
Earlier today Stephen Johnson, in a mailing list run by the The Unix Heritage Society , described the birth of the standard error concept: the idea that a program's error output is sent on a channel different from that of its normal output. Over the past forty years, all major operating systems and language libraries…
