BSD on Windows: Things I wish I knew existed
It’s 1995 and I’ve been nearly two years in the professional workspace. OS/2 is the dominant workstation product, Netware servers rule the world, and the year of the Linux desktop is going to happen any moment now. If you weren’t running OS/2, you were probably running Windows 3.1, only very few people were using that…

A fast, growable array with stable pointers in C
My last article about generic data structures in C was written to set the stage for today’s topic: A data structure with constant time indexing, stable pointers, and works well with arena allocators. Its been independently discovered by multiple programmers over the years and so goes by different names. A 2001 paper…

C Runtime Overhead (2015)
What do you do when libc is your bottleneck? If the total runtime of your process is under 10ms, most of this time (depending on your hardware) is spent waiting for the linker and C runtime to set things up. If you compare this to the Latency Numbers Every Programmer Should Know , it falls right above "disk seek" and…

At Scale, Rare Events Aren’t Rare
I’m a connoisseur of failure. I love reading about engineering failures of all forms and, unsurprisingly, I’m particularly interested in data center faults. It’s not that I delight in engineering failures. My interest is driven by believing that the more faults we all understand, the more likely we can engineer…

Getting 50 GB/S Back from the Apple Neural Engine
An RTL performance erratum in the Apple M3 Neural Engine throttles DRAM weight streaming throughput down to 17–19 GB/s from the nominal 45–60 GB/s, whenever the total weight size is an integer multiple of 1 MiB, which currently affects 7 of ANEMLL ’s 15 models. Avoiding the problematic path in the kernel DMA engine's…

Speeding Up the Webcola Graph Viz Library with Rust and WebAssembly
For a recent project I've been working on, I wanted to include a graph showing the relationships between different artists on Spotify. Spotify provides the data directly from their API, and I had everything set up to pull it for a user's top artists and into the browser.

Microsoft Zero and DeepSpeed: Memory Efficient Large Neural Network Training
The latest trend in AI is that larger natural language models provide better accuracy; however, larger models are difficult to train because of cost, time, and ease of code integration. Microsoft is releasing an open-source library called DeepSpeed, which vastly advances large model training by improving scale, speed…

ldd arbitrary code execution (2009)
The `ldd` utility is more vulnerable than you think. It's frequently used by programmers and system administrators to determine the dynamic library dependencies of executables. Sounds pretty innocent, right? Wrong! In this article I am going to show you how to create an executable that runs arbitrary code if it's...

Haiku package management
I’ve long since been a die-hard BeOS fan and have been running the open-source recreation Haiku for many years. I think it’s interesting to explore the “alternative OS” world and consider some great ideas that for whatever reason never caught on elsewhere. The way Haiku handles package management and its alternative…
