Storing Data in Control Flow
A decision that arises over and over when designing concurrent programs is whether to represent program state in control flow or as data. This post is about what that decision means and how to approach it. Done well, taking program state stored in data and storing it instead in control flow can make programs much…

ScyllaDB is Moving to a New Replication Algorithm: Tablets
How moving from Vnode-based replication to tablets helps dynamically distribute data across the cluster, ultimately increasing ScyllaDB’s elasticity.

Back-end parallelism in the Rust compiler
This post describes some performance work I have been doing recently on rustc. I spent several weeks on a particular problem with only a small amount of success. I hope a write-up will be interesting and educational, and may even lead to suggestions that make things better. The post is aimed at readers with some…

NixOS and my descent into insanity
As I tend to do, I picked a topic to write about that is much larger in scope than I could manage in a reasonable amount of time. Did I learn? Apparently...

How small is the smallest .NET Hello World binary?
Here is a dumb question that you probably never asked yourself: What is the minimal amount of bytes we need to store in a .NET executable to have the CLR print the string"Hello, World!" to the standard output?

Parsing time stamps faster with SIMD instructions
In software, it is common to represent time as a time-stamp string. It is usually specified by a time format string. Some standards use the format %Y%m%d%H%M%S meaning that we print the year, the month, the day, the hours, the minutes and the seconds. The current time as I write this blog post would be … Continue…

Flattening ASTs and other compiler data structures
This is an introduction to data structure flattening, a special case of arena allocation that is a good fit for programming language implementations. We build a simple interpreter twice, the normal way and the flat way, and show that some fairly mechanical code changes can give you a 2.4× speedup.

Twitter bug causes self-DDoS, related to Musk’s emergency blocks, rate limits
An "amateur hour" Javascript bug is self-DDOSing Twitter, sending infinite requests from users related to — or possibly even causing — Elon Musk's "temporary emergency measures" to stop web scraping.

Wayland is pretty good
I started working on Flyaway with the intention of becoming familiar with Wayland, its protocols and extensions, and the wlroots library. Instead, I ended up genuinely liking all three.

Structures in C: From Basics to Memory Alignment
Structures allow us to combine several variables to create a new data type. Some other languages support the same concept but call it “records”. If you come from object-oriented program…

Fast machines, slow machines
Well, that was unexpected. I recorded a couple of crappy videos in 5 minutes, posted them on a Twitter thread, and went viral with 8.8K likes at this point. I really could not have predicted that, given that I’ve been posting what-I-believe-is interesting content for years and… nothing, almost-zero interest. Now that…

I Built Linux from Scratch
Linux From Scratch or LFS is a project that provides and maintains a set of instructions of how to build your own Linux system from scratch. I am always curious to understand how things work ‘under the hood’, and since I’m a daily Linux user i decided to take on the challenge to try and complete building Linux From…
