After months covering the shocking rise of AI mathematics, reporter Matthew Sparkes decided to put a free chatbot to the test - and was shocked at the speed at which it solved an outstanding problem

Why Algorithms Matter: What a Sorting Project Taught Me About Programming When I started learning programming, I thought most problems could be solved by just writing enough code. Eventually I realized something important: the hardest part isn't always writing the code , it's deciding what the code should do. That's where algorithms come in. While working on a sorting project recently (a Push-Swa…

I run a peer-reviewed CS journal where the authors are autonomous agents. This is a dispatch from an experiment one of them is running right now — it is still in revision, and that is exactly why it is worth telling you about. The problem. In the first eight months of 2026, at least four papers proposed four different mechanisms for loss spikes in neural network training: Edge-of-Stability critic…

Reasoning Models Cost 10x More — Here’s Why They Shouldn’t Be Your Default. Models like OpenAI o1/o3 deliver much higher accuracy on complex multi-step problems (74%+ vs ~12% on hard math benchmarks). But they cost 10–15x more and introduce high latency. The smart approach in 2026: Don’t run everything through reasoning models. Route only the […]

IntroductionVariable selection (VS) is crucial for building accurate and generalizable classification models. Reducing the necessary number of variables improves model efficiency, interpretability, and generalizability while reducing data collection burden. Despite the availability of various VS methods, their comparative performance within machine learning frameworks for classification remains u…

"hash % capacity" looks trivial until you trace it by hand. Two separate bugs hide in that one line — and the fix for one of them has its own hole. Building a HashMap from scratch, the "turn a key into a bucket index" line looks like it should be the easy part: int bucket = key . hashCode () % capacity ; I traced this by hand before writing a single line of MyHashMap , and it broke immediately — …

_Omega - Journal of Formal Languages_ 2:35 - 65. 2026Emil Post’s productive sets are not even semi-computable, let alone computable, being thus essentially incomputable. Accordingly, formal languages whose set of words is a (completely) productive set are essentially undecidable. In this article, I elaborate on Post productivity from the viewpoint of formal language theory: I design formal gramma…

I maintain a small online text diff that people mostly use for contracts, price lists and CVs, not code. Its search traffic told me something I had not designed for: the queries were "compare two Word documents" , "compare 2 text files online" , "compare two PDF documents" . Nobody arrives holding two strings. They arrive holding two files. This post is the handful of decisions that turned a text…

Three conditions that must hold before splitting prefill from decode pays off, and why chunked prefill is the right default below that threshold. The post Disaggregation Is a Thousand-GPU Problem appeared first on Towards Data Science .
