Fire is an interesting graphics problem. Past approaches generally faked it. For example, Lord of the Rings used sprites with lots and lots of smoke (the fluid sim was too expensive at the time, even for movies). Real-time applications like video games have pretty much exclusively used non-physical approaches.
When Boris entered the room, Prince Andrey was listening to an old general, wearing his decorations, who was reporting something to Prince Andrey, with an expression of soldierly servility on his purple face. “Alright. Please wait!” he said to the general, speaking in Russian with the French accent which he used when…
Right after getting my degree, I was lucky to be hired into a small but decent R&D department as an embedded software engineer. My first task was to create a Unit Test project and have it run in our build pipeline after compilation. I was not particularly excited about this task, it seemed like busywork to me. I…
MySQL needs little introduction. Over the last 28 years it has become one of the most widely deployed SQL databases. MySQL is primarily used for online transaction processing (OLTP) workloads, but is also deployed as a part of OLAP and queuing systems.
Singular Value Decomposition (SVD) is a fundamental concept in linear algebra, and it is particularly important in the field of machine learning for tasks such as dimensionality reduction, data compression, and noise reduction.
I recently created some “bed sensors” for my smart home that detect if one of us, or both of us, is in bed. I use a couple of pressure mats that detect when weight is applied to them, and stuck then under our mattress at around hip level and these tell my Home Assistant home automation platform if
It turns out that you can't trust any USB type A power adapter to be within spec.
As adding more code to a product will slow down development, we should view all code as technical debt.
RFC 9518: Centralization, Decentralization, and Internet Standards has been published after more than two years of review, discussion, and revision.

Our product range covers CubeSat, SmallSat and specific client requirements. Simple, solid-state, robust design…
.NET 8 includes significant improvements to the Hardware Intrinsics feature.
Software companies come in many sizes. There are small startups, medium-sized companies, and huge enterprises. As you might expect, startups are usually lean and fast. Big companies that develop large applications move much more slowly. Those might be systems developed for many years or decades by hundreds of…
Suppose that the logic of your program depends on time. That is, you need to keep track of when something in the past happened, and what tim...
The Qt Quick Compiler has learned a few new tricks recently that can make your QML code run a lot faster.
Discussions: Hacker News (64 points, 3 comments), Reddit r/MachineLearning (219 points, 18 comments) Translations: Simplified Chinese, French, Korean, Russian, Turkish This year, we saw a dazzling application of machine learning. The OpenAI GPT-2 exhibited impressive ability of writing coherent and passionate essays…
The case for giving programmers private offices with doors — why open offices destroy deep work, how interruptions cost far more than floor space, and what the research actually says.
Emacs incremental search (isearch) has an embarrassingly rich feature set. That said, I rarely use isearch beyond its basics for the twofold reasons: There are many isearch commands that are...
After my lost MacBook was returned to me with an Activation Lock on it, Apple refused to unlock it. Only after emailing Tim Cook could I get it unlocked.
Google could do more than just win the chatbot war: it is the one company that could make a universal assistant. The question is if the company is willing to risk it all.
I learned things
I've done a lot in my career. From working on business support software to big backend systems and even robotics. If there's been a consistent through-line to my career, it's the Ruby programming language.
Mathematics with a distinct visual perspective. Linear algebra, calculus, neural networks, topology, and more.
Introduction In this blog, we'll be going over some more advanced topics new in Postgres 16. Having some experience with Linux, Postgres, and SQL is necessary as we'll not only be going over these new features but also how to implement them. This blog was written using PostgreSQL 16 (Development Version) running on…
This year, the YJIT team has been working hard to improve and optimize YJIT. We’re proud to say that the version of YJIT to be included with Ruby 3.3 is leaps and bounds ahead of Ruby 3.2’s. It provides better performance across the board, while also warming up faster and using less memory. The 3.3 release is also…
Mistral AI is the most exciting AI research lab at the moment. They’ve now released two extremely powerful smaller Large Language Models under an Apache 2 license, and have a …

The “forever chemicals” found in the Cape Fear River were detected through a non-targeted testing method developed at UNC-Chapel Hill that broadens researchers’ abilities to identify the hazardous compounds.
Introducing Fly Kubernetes: If you want K8s on Fly.io, we built something for you.
From pure Python to AVX-512 assembly, optimizing cosine similarity reveals a 2,500x speedup through SIMD, FP16, and VNNI instructions on modern Intel CPUs.
