Yes, it was, in fact, a Unix system.

Disclosure: this is a write-up about my own side project — a combat analytics tool for AION 2. No affiliation with the game's publisher. Links at the end. Architecture A Windows desktop app: Rust backend + Tauri v2 webview UI . It passively captures the game's TCP traffic (npcap), reassembles streams, parses the game's undocumented binary protocol, feeds a combat model (damage, heals, buffs, deaths, boss detection), and pushes aggregates to a small JS frontend. Nothing touches the game client — no injection, no memory reading. If the packet didn't say it, we don't know it. Pain #1: the protocol is a moving target Nobody hands you a spec. The protocol is varint-heavy, partially compressed, and changes with game patches. You end up doing packet archaeology: capture a fight, stare at hex dumps, correlate "I pressed this skill at 19:32:04" with byte patterns, build a parser, and then — the fun part — keep it alive after every patch , usually reverse-engineering the diff within hours because your users' raids are tonight, not next week. One hard-won lesson: log everything behind toggleable trace categories. Our tracing setup keeps hot-path log callsites at literally zero cost when disabled (Rust tracing with Interest::never() + atomic per-category flags), so a user can flip a "Trace: Packets" checkbox, reproduce a bug, and send a log that actually contains the bytes we need. Pain #2: entity identity is a lie The single hardest correctness problem wasn't parsing — it was identity . A player is not one ID: your character has a stable "owner" entity that carries your buff bar, your damage lands under a transient combat entity whose ID changes between pulls, leave the dungeon and the game re-binds you to a brand-new ID, names arrive from different packets than damage, sometimes seconds later, sometimes never (mid-fight app start). Get any of this wrong and a healer's healing lands on a ghost row, or a player's buffs vanish from the saved fight because their ID was recycled 7

This is the entire Firefox browser rendering to a <canvas> element. Gecko, all UI components, and the Spidermonkey JS engine are all compiled and running in WebAssembly. Here are a few things you might find interesting: - This is fully end to end encrypted! We use the WISP protocol for TCP-over-websockets. - There is a novel WASM->JS JIT for experimental site speedup - This port cost over 25k in opus/fable tokens for debugging and JIT research This was just a fun experiment to push the boundarie

The Trump administration has not disclosed its cost estimates for the Iran war.

Since WIRED reported on Meta’s NameTag face recognition system, company executives have made confusing and conflicting remarks about its very existence.

Hey HN! I've always loved beautiful words. I also enjoy coming up with fun names for all the side projects and businesses that I'm working on, trying to find something unique with an available .com. After spending countless hours brainstorming names for different stuff, I built Spellsurf. It lets you explore words and combine their syllables to create new ones. You can also set rules for the generated words, making it easy to search for names that fit what you're looking for. People say to open

The safety board confirmed Tesla's account of the crash, which the company shared days after it happened last month.

Hi HN, I'm Kyle, the creator of Clipper, a container registry with 7x faster builds via lazy pulls and cache mount exports. In the process of implementing cache mount exports I ended up with a FUSE mounted filesystem backed by a remote content defined store. I went looking for fun things to do with it and found that there's not really a good way to keep Rust incremental build state around on ephemeral runners, so here we are. Rust generally uses https://github.com/mozilla/sccache for caching, bu

Roblox will be shutting down Roblox Connect, its video calling service introduced in 2023. Roblox Connect let you video chat with other people using your Roblox avatar, which would be able to mimic the movements you were making in real life. You could also run around with people on the call in a shared virtual […]

This weekend, cinephiles across the world will march to their local theaters to feast their eyes on Christopher Nolan's new adaptation of The Odyssey. It's on track to rake in anywhere between $80-$100 million in just a few days. People are clearly excited to see how Nolan uses cutting-edge filmmaking tech to make the Homeric […]

HiveLegacy is a "powerful primitive" that's likely capable of other nefarious actions.
