Apache Otava
Change Detection for Continuous Performance Engineering Otava performs statistical analysis of performance test results stored in CSV files, PostgreSQL, BigQuery, or Graphite database. It finds change-points and notifies about possible performance regressions.
AI Made Writing Code Easier. It Made Being an Engineer Harder
Yes, writing code is easier than ever. AI assistants autocomplete your functions. Agents scaffold entire features. You can describe what you want in plain English and watch working code appear in seconds. The barrier to producing code has never been lower. And yet, the day-to-day life of software engineers has gotten more complex, more demanding, […]
Ape Coding
Ape coding is a software development practice where a human developer deliberately hand-writes source code. Practitioners of ape coding will typically author code by typing it on a computer keyboard, using specifically designed text editing software. History The term was popularized when agentic coding (coding performed by AI agents) became the dominant form of software […]
RE#: how we built the fastest regex engine in F#
around a year ago, we built a regex engine in F# that not only outperformed the ones in dotnet, but went above and beyond competing with every other industrial regex engine on a large set of industry-standard benchmarks. additionally, it supports the full set of boolean operators (union, intersection, complement) and even a form of […]
Show HN: I built a zero-browser, pure-JS typesetting engine for bit-perfect PDFs
:: Deterministic typesetting for the programmable web. A pure-JS, zero-dependency typesetting engine that yields bit-perfect PDF output across any runtime—from Cloudflare Workers to the browser. Stop using Headless Chrome to print text. If you generate PDFs with headless browsers or HTML-to-PDF tools, you’ve accepted a compromise: heavy dependencies, memory leaks, and ”approximate” layout that shifts […]

The fadenstrahlrohre or Finebeam tube is used in conjunction with two Helmholtz coils to investigate the deflection of electron beams in electrical and magnetic fields, particularly the determination of the specific electron charge e/m, the Electron Charge […]
Microgpt explained interactively
Andrej Karpathy wrote a 200-line Python script that trains and runs a GPT from scratch, with no libraries, no dependencies, just raw Python. The script contains the complete algorithm that powers LLMs like ChatGPT. Everything else is just efficiency. Let’s walk through it piece by piece and watch each part work. Andrej did a walkthrough […]
