For the past few months, I’ve been curious about two technologies: the Zig programming language and Ethereum cryptocurrency. To learn more about both, I’ve been using Zig to write a bytecode interpreter for the Ethereum Virtual Machine. Zig is a great language for performance optimization, as it gives you fine-grained…
This article is about a bit of surprising behavior I recently discovered using Python's regex module (re) while developing SBOM tooling for CPython. Folks who've worked with regular expressions be...

One of my favorite features in Neovim is the Tree-sitter integration. It allows for fast syntax highlighting that works well even in an error state (often the case when you’re editing code), and it has additional semantics (you can differentiate between function parameters and local variables).
MIT CSAIL researchers introduce FeatUp, a model-agnostic framework designed to significantly enhance the spatial resolution of deep learning features for improved performance in computer vision tasks such as semantic segmentation, depth prediction, and object detection.
PostgreSQL isn’t just a simple relational database; it’s a data management framework with the potential to engulf the entire database realm. The trend of “Using Postgres for Everything” is no longer limited to a few elite teams but is becoming a mainstream best practice.
In just a few years, Flipper Zero has become so popular that it’s now surrounded by many myths. It’s no wonder that people in power are trying to make Flipper Zero illegal. As you might have seen in the news, the Canadian government plans to ban Flipper Zero
An Intel 8080 processor emulator written in less than 4K of C language and able to run CP/M. It won the Best of Show category (first place) of the 19th IOCCC. The 8080 originated the Zilog Z80 and started the personal computer's revolution.
Safari 17.4 adds vertical writing mode support for form control elements across macOS, iOS, iPadOS, and visionOS.
On Wednesday, March 13, 2024, Let’s Encrypt generated 10 new Intermediate CA Key Pairs, and issued 15 new Intermediate CA Certificates containing the new public keys. These new intermediate certificates provide smaller and more efficient certificate chains to Let’s Encrypt Subscribers, enhancing the overall online…
Quickwit 0.8 brings indexing and search at an unprecedented scale, indexing at 1PB/day and searching through 50 PB is a reality.
Tunnelmole is a free and open-source alternative to ngrok. It works out of the box with no port forwarding or networking config needed.
Impressive, but too late to the party
I hate having to use that word - "alleged" - because it's so inconclusive and I know it will leave people with many unanswered questions. (Edit: 12 days after publishing this blog post, it looks like the "alleged" caveat can be dropped, see the addition at the end of the post
This idea is particularly sticky because it was more or less true 50 years ago, and it's a passable mental model to use when learning sql. But it's an inadequate mental model for building new sql frontends, designing new query languages, or writing tools likes ORMs that abstract over sql.
The first entry on this blog was 20 years ago yesterday, first substantive one was 20 years ago tomorrow (first one that drew attacks on me as an incompetent was two days later). Back when I starte…
In this post, I’ll look at CVE-2023-6241, a vulnerability in the Arm Mali GPU that allows a malicious app to gain arbitrary kernel code execution and root on an Android phone. I’ll show how this vulnerability can be exploited even when Memory Tagging Extension (MTE), a powerful mitigation, is enabled on the device.
Silence can mean different things to different people in different situations. In this post, I’ll present a few incident scenarios and explore the role of the incident commander in breaking (…
We create the world's fastest and most efficient AI.
There are lots of interesting little subproblems in compilation like instruction selection, register allocation and instruction scheduling. These can be expressed in declarative interlinked way to constraint solvers.
When we released Stable Video Diffusion, we highlighted the versatility of our video model across various applications. Building upon this foundation, we are excited to release Stable Video 3D. This new model advances the field of 3D technology, delivering greatly improved quality and multi-view whe
I thought for sure that I’d previously written about the secret jelly packet & pickle-based system that chefs at the Waffle House use to “store” all of the orde
