Kafka at the low end: how bad can it get?
There is oft-quoted advice that Kafka does poorly as a job queue. I’ve experienced this myself, and I wanted to formalize it a bit. I’ll use the common architecture of a Web application submitting background jobs to workers via Kafka (for example, to generate a PDF of some report). Except for the use of Kafka […]

My LLM codegen workflow
tl:dr; Brainstorm spec, then plan a plan, then execute using LLM codegen. Discrete loops. Then magic. ✩₊˚.⋆☾⋆⁺₊✧ I have been building so many small products using LLMs. It has been fun, and useful. However, there are pitfalls that can waste so much time. A while back a friend asked me how I was using LLMs […]
Nuclear fusion: WEST beats the world record for plasma duration
1,337 seconds: that was how long WEST, a tokamak run from the CEA Cadarache site in southern France and one of the EUROfusion consortium medium size Tokamak facilities, was able to maintain a plasma for on 12 February. This was a 25% improvement on the previous record time achieved with EAST, in China, a few weeks […]
Tensor Evolution: A Framework for Fast Evaluation Using Recurrences
Abstract:This paper introduces a new mathematical framework for analysis and optimization of tensor expressions within an enclosing loop. Tensors are multi-dimensional arrays of values. They are common in high performance computing (HPC) and machine learning domains. Our framework extends Scalar Evolution – an important optimization pass implemented in both LLVM and GCC – to tensors. […]

Among top researchers 10% publish at unrealistic levels, analysis finds
About 10% of the most influential researchers worldwide in various scientific fields, including chemistry, are achieving ‘implausibly high’ publication and new co-author rates. Many are producing hundreds of papers each year and gaining hundreds to thousands of new collaborators annually, according to recent analysis by researchers at King Fahd University of Petroleum and Minerals in […]
Launch HN: Promptless (YC W25) – Automatic updates for customer-facing docs
Hi HN! I’m Prithvi, and my co-founder Frances and I built Promptless (https://gopromptless.ai), an AI teammate that proactively updates docs while you ship software. There’s a demo video at https://youtu.be/pmslSl8dOgE, and also a “Live Demo on Your Own Docs” at https://gopromptless.ai/demo where you can plug in the URL to any existing docs site and simulate […]
Try Thinking and Learning Without Working Memory (2008)
Imagine dialing a phone number by having to look up each digit one at a time in the phone book. Normally, you look up the number and remember all seven digits long enough to get it dialed. Even with one digit at a time, you would have to remember each digit long enough to get […]
