New homes in London were delayed by ‘energy-hungry’ data centres
The rapid growth of “energy-hungry” data centres is delaying new homes in London, just as its housing crisis is “at its worst”, a new report has warned. Data centres are giant warehouses full of powerful computers used to run digital services, such as streaming and artificial intelligence. However, they require masses of electricity from the […]
Euler Conjecture and CDC 6600
MarDie: it’s also possible to compute the integer fifth-powers at compile time. I don’t think this warning applies here because the array is small, but the danger of this approach in general is that the executable file must contain that compile-time computed data, which means that it takes time to load that memory from disk […]
Apex GPU: Run CUDA Apps on AMD GPUs Without Recompilation
Run NVIDIA CUDA applications on AMD GPUs without recompilation What is APEX GPU? APEX GPU is a lightweight CUDA→AMD translation layer that allows unmodified CUDA applications to run on AMD GPUs using LD_PRELOAD. No source code changes, no recompilation required. # Your existing CUDA application ./my_cuda_app # Same application on AMD GPU – just add […]

Acme, a brief history of one of the protocols which has changed the Internet
ACME, a brief history of one of the protocols which has changed the Internet Security Preamble I would like to share with you this article I wrote about the ACME protocol, which I “fell in love with” about ten years ago. It is for me a way to give back to this fantastic Free Software […]
Jujutsu Worktrees Are Convenient
Jujutsu worktrees are very convenient! In git, worktrees are an old concept. The idea is that you can effectively work on your project in 2 different folders with different states while sharing a single history and git state. That means it is smaller and less work to keep up than 2 separate clones, and you […]
Show HN: I built a dashboard to compare mortgage rates across 120 credit unions
Buying a home or refinancing a mortgage is tough enough without confusing ads from banks and big lenders. Credit unions can offer competitive rates compared to big banks because they’re member-owned, non-profit institutions. They focus on serving their members, not maximizing profits for shareholders. But without big budgets and marketing departments, credit union rates aren’t […]
Everyone in Seattle hates AI
I grabbed lunch with a former Microsoft coworker I’ve always admired—one of those engineers who can take any idea, even a mediocre one, and immediately find the gold in it. I wanted her take on Wanderfugl 🐦, the AI-powered map I’ve been building full-time. I expected encouragement. At worst, overly generous feedback because she knows […]
Lie groups are crucial to some of the most fundamental theories in physics
In mathematics, ubiquitous objects called groups display nearly magical powers. Though they’re defined by just a few rules, groups help illuminate an astonishing range of mysteries. They can tell you which polynomial equations are solvable, for instance, or how atoms are arranged in a crystal. And yet, among all the different kinds of groups, one […]
