So what is the deal with A/UX anyways?
The year is 1983, and several Apple employees visit Brown University, and get some idea of what Universities want in a computer for the coming future. The big buzz of the era was the so called 3M machine:

Why isn't memset() async-signal-safe?
Really, POSIX? Really? memset() isn't async-signal-safe? How is it not safe? … oh … that's why

The lost malloc()
Prompted by another project idea that popped into my mind, I did some Unix archaeology and looked at the original sources . This is the most fun I've ever had reading someone else's code - probably due to the historical significance. But also because of how delightfully approachable it was, compared to modern…

A Deep Dive into HandBrake and Video Transcoding
An obvious interest area of mine is in ripping (and watching) movies using my Mac. I've talked about everything from installing the tools I use to how I rip to how to make sure I update the ripping tools . And though I've included some comparison pictures in the how-I-rip article, I've never done a deep dive into the…

Branchless Coding in Go
So, I was recently inspired by a coworker’s design to pack what would have been JSON (JavaScript Object Notation) data into a bunch of bit fields in an array of 64-bit elements. Binary arithmetic, bit-packing, and high performance are fun for me, so I thought of some ways to improve it, for learning purposes. Then I…

Debugging macOS Kernel Using VirtualBox
Update: In the HN discussion, awalton mentioned you can set CPUID flags in VMWare. Simply adding cpuid.7.ebx = "-----------0--------------------" to the vmx file will disable SMAP. Late last year, I upgraded my old MBP to the 2016 model with a Skylake processor. As I was debugging a kernel exploit, it turned out that…

Windows 9x Video Minidriver HD+
The OS/2 Museum has made available the first version of a display driver disk for Windows 9x running on VirtualBox . The driver uses a linear framebuffer and supports 8/16/24/32bpp modes with resolutions up to 1920×1200 pixels (see more below). The driver is not accelerated but tends to be very speedy on modern…

An History of Nvidia Stream Multiprocessor
I spent last week-end getting accustomed to CUDA and SIMT programming. It was a prolific time ending up with a Business Card Raytracer running close to 700x faster [1] , from 101s to 150ms. This pleasant experience was a good pretext to spend more time on the topic and learn about the evolution of Nvidia architecture…

Call me maybe: Redis redux
In a recent blog post , antirez detailed a new operation in Redis: WAIT . WAIT is proposed as an enhancement to Redis’ replication protocol to reduce the window of data loss in replicated Redis systems; clients can block awaiting acknowledgement of a write to a given number of nodes (or time out if the given threshold…

AWS Nitro System
At Tuesday Night Live with James Hamilton at the 2016 AWS re:Invent conference, I introduced the first Amazon Web Services custom silicon. The ASIC I showed formed the foundational core of our second generation custom network interface controllers and, even back in 2016, there was at least one of these ASICs going…
