What fork() Actually Copies
What fork() Actually Copies | Daniel’s Tech Blog ← Home 2026-03-28 Shallow changes can have consequences at the bottom of the ocean. This post is an account of something that happened to me recently, and the story is still open. The services are stable, the revert held, and a pull request is sitting there waiting […]
Lat.md: Agent Lattice: a knowledge graph for your codebase, written in Markdown
A knowledge graph for your codebase, written in markdown. The problem AGENTS.md doesn’t scale. A single flat file can describe a small project, but as a codebase grows, maintaining one monolithic document becomes impractical. Key design decisions get buried, business logic goes undocumented, and agents hallucinate context they should be able to look up. Compress […]
LinkedIn uses 2.4 GB RAM across two tabs
I don’t understand who uses that network anymore. Everytime I login it’s all ai generated stories next to ai generated flavor images of people sounding like a parody of themselves (”what taking my kids to school taught me about business scaling”). Out of all places to doomscroll, why choose the one that feels like an […]

Solar is winning the energy race
Since the turn of the century, the expansion of solar power has surpassed expectations, more than any other energy source. Once extremely expensive and only used in remote regions, space travel or pocket calculators, today’s solar modules — easy to set up and operate — generate cheap electricity all over the world. Global solar energy […]
What Category Theory Teaches Us About DataFrames
Every dataframe library ships with hundreds of operations. pandas alone has over 200 methods on a DataFrame. Is pivot different from melt? Is apply different from map? What about transform, agg, applymap, pipe? Some of these seem like the same operation wearing different hats. Others seem genuinely distinct. Without a framework for telling them apart, […]
Show HN: Public transit systems as data – lines, stations, railcars, and history
Beijing Metro Beijing The Beijing Subway is a rapid transit system serving Beijing, China. It is the world’s busiest and one of the longest metro systems, having surpassed Shanghai in total length in 2023. Originally opened in 1969 as China’s first subway, it has undergone massive expansion, particularly after Beijing won the 2008 Olympics bid. […]
The road to electric – in charts and data [UK]
What is the RAC doing to help drivers make the switch to electric? The RAC is leading the way when it comes to supporting drivers in the switch to electric vehicles. An ever-increasing number of our patrol vans have built-in emergency mobile charging systems capable of giving an out-of-charge electric car enough power to be […]
A Recipe for Steganogravy
author’s note The following justification is nonsense, I just thought the idea of encoding data in recipe blogs was fun and silly. With AI scrapers and government agencies roaming the internet and snarfing down every last byte (hoping to profit when you mistakenly publish useful information online), it’s gotten harder to share data without it […]
