1. Why Janet? (2023)
⭐ 106 💬 38 👤 yacin 🔗 Discuss on HN
I never thought it could happen to me. But for the past couple years, my go-to programming language for fun side projects has been a little Lisp dialect called Janet. (print “hey janet”) I like Janet so much that I wrote an entire book about it, and put it on The Internet for free, in the hopes of attracting more Janetors to the language.

⭐ 1861 💬 421 👤 ssiddharth 🔗 Discuss on HN
Yesterday, a slew of Instagram accounts, including some high profile ones like the Obama White House account, seemingly got hacked. I’ve spent almost a decade and a half identifying vulnerabilities and exploits at unicorn scale, but this is hands down the most unserious, “almost too stupid to be true” of them all.

7. macOS needs its grid back
⭐ 270 💬 157 👤 ranebo 🔗 Discuss on HN
Two decades ago I had a better Mac desktop experience than I have today. I only had a single low res (by todays standards) screen, yet I felt like Hugh Jackman in Swordfish - deftly navigating more than nine displays without thinking, muscle and spatial memory working seamlessly together. > TLDR; I built an app to return macOS spaces to its Pre-Lion Grid-enabled Glory.

10. Chipotlai Max
⭐ 240 💬 38 👤 nigelgutzmann 🔗 Discuss on HN
Chipotlai Max is a humorous fork of the OpenCode AI coding agent that replaces the default LLM with “Pepper AI” — a mock LLM provider running on “stolen Chipotle compute.” It’s a community project jokingly expanding to add providers from Home Depot, Lowes, Target, and Starbucks. Think of it as a novelty project that parodies the AI/LLM provider ecosystem with fast-food and retail-themed compute providers.
