The magic in AI coding assistants isn't the code -- it's the prompts. I studied the externally observable behavior of Claude Code and recreated it from scratch in Python with the e…

I think our memories are rooted in time and space. "Which years did we go on our family holiday to Scotland? Can I see all my videos from when my kids were toddlers? Let's see that…

Hello, HN. Over the past three decades, my camera photo collection has grown to almost a terabyte, all on OneDrive. I've been wanting a way to view it all on a map, to filter by da…

My team has a large ocaml codebase and a dual build system (buck2 and dune). The two have roughly similar: dune faster at the raw speed of invoking ocaml build tools, buck2 winning…

I'm struggling to understand how a moat can have a CRACK in it.

In my web-scraping I've gravitated towards the "cheerio" library for javascript. I kind of don't want to use DOMParser because it's browser-only... my web-scrapers have to evolve e…

I presume it means things like "does cross-file go-to-def and find-all-references work instantly after opening a file?" In most IDEs these things take seconds or minutes to become …

That's a good example because it leads to truth that NO up-front tagging will ever anticipate all the searches you might make in future. There are so many possible searches. I figu…

I got into ultramarathon swimming because of that movie. I've since done numerous unaccompanied 12mile swims in nearby Lake Washington (Seattle), several accompanied sea crossings,…

What does it mean to open-source or MIT-license a "file format"? The MIT license is a license about copyrighted software, allowing people to use/modify/publish that software. But a…

I wrote https://github.com/ljw1004/seaoflogs - an interactive filtering tool, for similar ends to what's described here. I wrote it because my team was struggling to analyze LSP lo…

Those numbers are easy to find on google! Iowa 14-18" average topsoil depth in 1900, 6-8" in 2000. I'm not sure anyone could tell acceleration/deceleration over this timescale.

That was a deeply beautiful interview. Such profound yet relatable thoughts, humbly expressed.

I felt exactly the same. Silicon valley attitude "woah dude that's awesome". UK fenland attitude "don't get your hopes up and know your place".

I think there is an easy way to prove this to users. Make your thing be a single page self contained html file which they save into the hard disk. Then they can trust the restricte…

In what sense is this solution "fair"? What definition of fairness is being used? This seems like a solution where rich people get the good things and poor people don't. I wouldn't…

My job over the past several years has been to work on IDE integrations for a language (Hack, Flow). Prior to that I worked on C#/VB "Roslyn" system at Microsoft, which is entirely…

WinRT isn't tied to store apps. You can use most of it just fine from .NET/C++ desktop apps. (not the XAML bits obviously) https://www.nuget.org/packages/UwpDesktop/
