Exploring Clang/LLVM optimization on programming horror
Recently, I’ve come across a not so efficient implementation of a isEven function (from r/programminghorror ).

Object-Oriented Entity-Component-System Design
About two months ago, I decided to start developing a fresh codebase for my voxel project – something that many indie developers are probably all-too familiar with, including myself. This time around, there were three major features that I wanted to implement:

Let's write a compiler, part 3: A parser
Tokenizing the source code input is a great start for our compiler. Now let's turn our attention to parsing the PL/0 grammar. Once we have finished with the parser, the front end of our compiler will be finished and we will have a PL/0 validator. This is a program that can read in PL/0 source code and inform the user…

What can be learned from studying long gone development practices?
Current ideas about the best way of building a software system are heavily influenced by the ideas that captured the attention of previous generations of developers. Can anything of practical use be learned from studying long gone techniques for building software systems?

Why is learning functional programming so damned hard? (2019)
My Functional Programming journey was filled with dead ends, false starts, failed attempts and frustration. And I suspect that I’m not…

Let's write a compiler, part 1: Introduction, selecting a language, and planning
I think we all knew this might be coming once we finished up with our assembler . While we can in theory solve any computable problem by writing the appropriate assembly for our assembler, writing assembly code can be a bit more cumbersome than a high-level language. There is a reason why we did not write our…

Closing 45% of the open Emacs bugs
Hey, that took only a month, which means that it’s time, once again, to display some Emacs charts. And since this is the tenth post in this series, I thought I’d natter on even more tha…

Thoughts On Lisp And Racket (2019)
I plan on writing about why I am interested in the Lisp family of languages. It will probably come out in stages.

How Actors Work Internally in Swift
Lets explore how actors work under the hood, using Swift's own source code as a guide to finding out how they work inside the compiler.

Do not do in code what can be done in infrastructure (2017)
Or subtitle: Maybe distributed programming is no longer a programming problem? (For the obvious impaired: This is meant to be more thought provoking than an actual truth) Over the last decade we ha…

When zero cost abstractions aren't zero cost
Rust is built around the concept of “zero cost abstraction”. The idea is that you can write human-friendly high level code and the compiler will give you for free performance at least as good as any optimized low level code you could have written yourself. With zero cost abstraction, you no longer have to trade off…

Beyond coupling and cohesion: strategies for un-fucking yourself

Bloom Filters: More than a space-efficient hashmap
A bloom filter is one of those data structures you are probably already aware of, or have at least heard about. For those looking for a simple recap, they are a probabilistic data structure which can …

Revisiting Prechelt’s paper comparing Java, Lisp, C/C++ and scripting languages
In 1999, Lutz Prechelt published a seminal article on the COMMUNICATIONS OF THE ACM (October 1999/Vol. 42, No. 10) called Comparing Java vs. C/C++ Efficiency Differences to Interpersonal Differences , henceforth Java VS C , which seems to have later (March 2000) been expanded into a full paper, An empirical comparison…

Constexpr is a Platform (2020)
Let me share a useful insight with you: constexpr is a platform. Just like you write code that targets Windows or a microcontroller, you write code that targets compile-time execution. In both cases you restrict yourself to the subset of C++ that works on your target platform, use conditional compilation if your code…

The macOS Sandbox File Limit
There has recently been some renewed discussion on Twitter about the limitation that the macOS sandbox places on the number of open files an app can access at once. Apps are still running into problems because of this limitation, and there is not a lot of technical detail available on it outside of Apple, so I’d like…

; Echo “Shell Injection”
This is an introductory article about shell injection, a security vulnerability allowing an attacker to execute arbitrary code on the user's machine. This is a well-studied problem, and there are simple and efficient solutions to it. It's relatively easy to design library API in such a way as to shield the application…
