Education must go beyond the mere production of words
“The end then of Learning,” wrote John Milton in 1644, “is to repair the ruines of our first Parents.” The image is hard to improve: education as repair, as recovery, as the restoration of capacities diminished by sin and neglect. Four centuries later, in the age of generative artificial intelligence (AI), that image has become […]
FusionCore: ROS 2 sensor fusion (IMU and GPS and encoders)
ROS 2 sensor fusion SDK. Combines IMU, wheel encoders, and GPS into one reliable position estimate. Self-tuning noise covariance. Apache 2.0. What problem does this solve? Every mobile robot needs to know where it is. It gets this from multiple sensors: IMU, wheel encoders, GPS: each of which is imperfect in its own way. IMUs […]
Generalised plusequals
leontrolski – Generalised plusequals ⇦ 2026-04-24 I have a quarter baked language I’ve been working on. It’s mostly crap, but a syntax idea fell out that I think is pretty neat. The following are equivalent in many languages: x = x + 1 x += 1 Reassigning is cool as it’s lexically scoped so easy […]
Google to invest up to $40B in Anthropic in cash and compute
Google plans to invest up to $40 billion in Anthropic and support the AI firm’s growing computing needs, Bloomberg reports. The Alphabet subsidiary is committing to invest $10 billion now, at a $350 billion valuation for Anthropic, with another $30 billion to follow if Anthropic hits certain performance targets, according to Anthropic. The promise of […]
Tell HN: Claude 4.7 is ignoring stop hooks
I’ve been using Anthropic’s hook features [0] since they were introduced. It allows me to inject determinism into my workflows. This worked perfectly until 4.7. Now, Claude routinely ignores the hook rules. For example, I have a stop hook that prevents Claude from stopping if a source file has been changed and no tests have […]
My audio interface has SSH enabled by default
last year i bought a Rodecaster Duo to solve some audio woes to allow myself and my girlfriend to have microphones to our respective computers when gaming together and talking on discord in the same room without any echo, and to be able to swap that to my work pc easily. the rodecaster is really […]
Could a Claude Code routine watch my finances?
Watch intro video A few months ago, I stood up a fiddly daily cron-job to log into my bank, credit card, and brokerage/retirement accounts. It was powered by Codex CLI running non-interactively, and had a fairly simple job: using the Chrome DevTools MCP, log into each website, extract balances and recent transactions, then send my […]
The Classic American Diner
Although diners may not be as ubiquitous as they once were, they are a distinctive part of American food culture, and they can still be found dotting the landscape. Images of these establishments from the Library of Congress collections offer a reminder of some of their common characteristics, and may also bring a wave of […]
OpenAI releases GPT-5.5 and GPT-5.5 Pro in the API
Released GPT-5.5, a new frontier model for complex professional work, to the Chat Completions and Responses API, and released GPT-5.5 pro for Responses API requests, including through Batch, for tougher problems that benefit from more compute. GPT-5.5 supports a 1M token context window, image input, structured outputs, function calling, prompt caching, Batch, tool search, built-in […]
There Will Be a Scientific Theory of Deep Learning
Abstract:In this paper, we make the case that a scientific theory of deep learning is emerging. By this we mean a theory which characterizes important properties and statistics of the training process, hidden representations, final weights, and performance of neural networks. We pull together major strands of ongoing research in deep learning theory and identify […]
