A System-Witch’s Package Manager Murder Mystery
It was a calm day on the puppy-linux thinkpad. The CPU was cool, the RAM was operating at double data rate, and a gentle breeze flowed through the chassis as the fan whirred away. A girl wanted to log onto Discord to chat with her friends, but much to her dismay, Discord needed a package update! No matter, such things…

TypeScript as fast as Rust: TypeScript++
TL;DR: This is a proposal to create a language that sits somewhere between Typescript and Rust, and which you can incrementally adopt if you already use Typescript.

Hand-optimizing the TCC code generator
I am on a number of different compiler mailing lists. One of those is the mailing list for the Tiny C Compiler . Imagine my surprise when a recent email mentioned our latest series and suggested trying a similar approach to improve the code generator in TCC. I was interested to see if there were any low-hanging fruit…

The Tower of Weakenings: Memory Models for Everyone
In my previous article I looked at the ways that Rust could be better at pointers. Half of the problems were fundamental issues that affect basically every programming language that lets you mess with pointers directly, and the other half were rust-specific issues. My article also proposed two solutions: for the…

The cult of Amiga and SGI, or why workstations matter
I’m considered to be a server guy. I had access to some really awesome server machines. Still, when computers come up in discussions, we are almost exclusively talk about workstations. Even if servers are an important part of my life, that’s “just” work. I loved the SGI workstations I had access to during my…

Meta quickly detects silent data corruptions at scale
Silent data corruptions (SDCs), data errors that go undetected by the larger system, are a widespread problem for large-scale infrastructure systems. Left undetected, these types of corruptions can…

What is triald and why is it taking so much disk space?
Is a process named triald stealing lots of CPU? Or maybe ~/Library/Trial is huge, or filling your backups? Maybe it’s all just one of Apple’s Experiments.

Your computer is a distributed system
Many have observed that today's computers are distributed systems implementing the abstraction of the shared-memory multiprocessor. The wording in the title is from the 2009 paper " Your computer is already a distributed system. Why isn't your OS? ". Some points from that and other sources:

Converting integers to decimal strings faster with AVX-512
In most systems, integers are stored using a fixed binary representation. It is common to store integers using 32-bit or 64-bit words. You sometimes need to convert it to a string. For example, the integer 12345 might need to be converted to the five characters '12345'. In an earlier blog post, I presented the simpler…

Oxide on My Wrist: Hubris on PineTime was the best worst idea
In my last Oxide-related post I got Oxide’s Propolis software running and said I might try and get their sled agent up and running next. Anyways that didn’t happen. Instead I ended up reading datasheets, writing rust codegen, spending 16 gigs of ram for an hour to build docs for a crate that’s just a glorified bundle…

Intel Virtualization and Apple Silicon
The transition to Apple Silicon brought about many exciting things, but one of the capabilities left behind was access to the world of Intel-based virtual machines. X86_64 just isn't a trivial architecture to emulate, and it may never be feasible to do so on Apple Silicon at a useful speed as the operating systems you…

A FOSS proposal for a new type of OS for a new type of computer (2021)
A possible next evolutionary step for computers is persistent memory: large capacity non-volatile main memory. With a few terabytes of nonvolatile RAM, who needs an SSD any more? I will sketch out a proposal for how to build an versatile, general-purpose OS for a computer that doesn't need or use filesystems or files…

Whatever happened to QuickTime?
QuickTime ruled from 1991-2019, and was bigger than Apple itself. But can you name what replaced it, and whether it works as well?

AWS Graviton vs. M1 vs. M1 Pro Node.js Benchmarks
I am lucky in that I have a few side projects which have grown up to become full fledged companies. One of them builds little tools to detect different types of financial crime.
