The Vulkan Working Group at Khronos has developed a set of video format decode and encode extensions, collectively referred to as Vulkan Video. Today, with the release of Vulkan 1.3.277, the Working Group is proud to announce the new Decode AV1 video extension. Similar to the Vulkan project in its goals, AV1 is a…
There’s a whole lot of buzz around the new Qwen2.5-Coder Series of open source (Apache 2.0 licensed) LLM releases from Alibaba’s Qwen research team. On first impression it looks like …
I am somehow very late to learning CUDA. I didn’t even know until recently that CUDA is just C++ with a small amount of extra stuff. If I had known that there is so little friction to learnin…
In September, machine learning engineers at Mozilla filed a bug report indicating that Firefox was consuming excessive memory and CPU resources while running Microsoft’s ONNX Runtime (a machine learning library) compiled to WebAssembly.

Simulating an entire cell using kinetic parameters of reactions in a well-stirred environment
Over the years, I've read a lot of books on software engineering. Agile books in particular like to refute the "Waterfall Model". Every t...

How to kill off a top source of browser exploits
Manage entire Python projects and even Python itself with a single unified tool.
A C program that writes "hello, world!" to the console using inline assembly instead of standard library functions, demonstrating direct system call invocation.
Introduction Today’s post will take us in a slightly different direction than the last few. Today’s post will be about hooking up some Python code to the X-Plane flight simulator to enable development of an autopilot using PID (proportional-integral-derivative) controllers. I’ve been a fan of flight simulators for…
While much attention has been focused on high-level software architectural patterns, what is, in effect, the de-facto standard software architecture is seldom discussed. This paper examines the most frequently deployed architecture: the BIG BALL OF MUD
Blog for DoltHub, a website hosting databases made with Dolt, an open-source version-controlled SQL database with Git-like semantics.
When Simplicity is Preferrable to Efficiency
Async/await, or "async IO", is a new-ish Rust added async/await in 2019. For comparison, C# added it in 2012, Python in 2015, JS in 2017, and C++ in 2020. language feature that lets our programs do more than one thing at a time. It's sort of an alternative to multithreading, though Rust programs often use both…
Division is quite an expensive operation. For instance, latency of the 32-bit division varies between 10 and 15 cycles on the Cannon Lake CPU, and for Zen4 this range is from 9 to 14 cycles. The latency of 32-bit multiplication is 3 or 4 cycles on both CPU models.
My main project is to create an executable spec of the Intel Architecture but, every now and then, I get to take a broader look at ISA specifications and think about the strengths and weaknesses of other ISA specs: what makes them work well; and what techniques they could borrow from other specifications. Earlier this…
What did you do at work today? How about last week? I spent a couple of days in quarterly business reviews, and wrapped up yearly planning activities for AWS Data Exchange and AWS Marketplace. I also added some unit tests to a project that I am onboarding into.
I adore Nerves. I recently joined the core team. And I'll be doing my best to help people get along with this lovely way to co-mingle hardware and massively concurrent reliable software.
In 2023, we launched an AI-powered Chief of Staff for engineering leaders—an assistant that unified information across team tools and tracked critical project developments. Within a year, we attrac...
People complain about Rust syntax. I think that most of the time when people think they have an issue with Rust's syntax, they actually object to Rust's semantics. In this slightly whimsical post, I'll try to disentangle the two.
I've seen a couple of recent posts where the writer mentioned asking LLMs to do something with a certain probability or a certain percentage of the time. There is a particular example that stuck in my mind which I've since lost the link to (If you're the author, please get in touch so I can link through to you): The…
Go 1.23 added Iterators, so lets build a js like streaming api
There's no official support for system-versioned tables in Postgres yet, and the temporal extensions aren't supported on Azure/AWS/GCP. Let's implement it ourselves with 3 triggers and an index.
Now lets's change the grammar so that if we don't have an else condition we default to None .
Why Ruby’s Timeout is dangerous (and Thread.raise is terrifying)
OpenTelemetry round for 2023 and what to expect in 2024
Earlier today Stephen Johnson, in a mailing list run by the The Unix Heritage Society , described the birth of the standard error concept: the idea that a program's error output is sent on a channel different from that of its normal output. Over the past forty years, all major operating systems and language libraries…
