Show HN: Writing Arabic in English

My journey in creating a phonetic Arabic keyboard A phonetic keyboard is a type of keyboard layout designed to make typing in a particular language easier by mapping characters or letters to sounds rather than their traditional positions on the keyboard.

SQL needed structure

Published 2025-09-04 Here are two pages from the internet movie database: There are two things to note about these pages. The data on the page is presented in a hierarchichal structure.

Poisoning Well

Poisoning Well 31st March 2025 One of the many pressing issues with Large Language Models (LLMs) is they are trained on content that isn’t theirs to consume. Since most of what they consume is on the open web, it’s difficult for authors to withhold consent without also depriving legitimate agents (AKA humans or “meat bags”) of information. Some well-meaning but naive developers have implored authors to instate robots.txt rules, intended to block LLM-associated crawlers. User-agent: GPTBot D

Protobuffers Are Wrong (2018)

I’ve spent a good deal of my professional life arguing against using protobuffers. They’re clearly written by amateurs, unbelievably ad-hoc, mired in gotchas, tricky to compile, and solve a problem that nobody but Google really has. If these problems of protobuffers remained quarantined in serialization abstractions, my complaints would end there. But unfortunately, the bad design of protobuffers is so persuasive that these problems manage to leak their way into your code as well. Ad-Hoc and Bu

Ever since interstellar object 3I/ATLAS streaked into our solar system, astronomers have been scrambling to understand how this likely comet got here—and more importantly, perhaps, where it came from.

Tamagotchi Paradise trades stressful virtual pet parenting for nature and tranquility

On a random Saturday in August, I became the omnipotent caretaker of a newly formed planet, one born, according to the lore, from humankind's collective love of Tamagotchis past and present. An egg hatched and a planet sprang forth. Then another egg hatched down on the surface of that planet and a critter sprang forth. In the few weeks since, I've raised half a dozen more creatures across three different virtual habitats, slowly but surely turning my planet into a bustling hub of adorable alien
