A random mix from the whole library. Shuffle for a new set.
The AI reverse-engineered his laser cutter's G-code dialect and camera controls in 1 to 2 hours; now it places and cuts jobs with power and speed settings and diagnoses problems from scans.
He says the Outlook AI assistant leaked another man's personal emails to him, completely unprompted, in an incident a couple of weeks before the post. He calls tools like this leaky and untrustworthy.
A man used AI to build a full runbook of how his Linux desktop is set up, covering installed software, configs, hacks and workarounds. He then used the runbook to move to a new laptop in one afternoon, and the runbook now keeps itself up to date.
He used AI to draft a first email inquiry to a contractor. The AI pointed out that the contractor's DC license expired in 2025, a check he says he would not have thought to make.
Runs LLMs to audit the math in claimed arXiv solutions for his ranked open-problems list; audits already found six faulty proofs that had caused problems to be wrongly marked resolved.
J.R. Rivera, a father and retired educator, used his agent 'Smarty' for four parenting pain points: finding the best local Charmin deal ($4.99 at Walgreens), booking FLL-TYS flights for his son's June 2027 Pigeon Forge baseball tournament ($1,008-$1,103), organizing the kids' overlapping GameChanger sports calendars into his main calendar, and buying a 30-inch Rawlings Icon Fest Light Blue USSSA bat ($399.99).
A statistician had argued that class balancing helps mini batch gradient descent. He had the AI Astra design and run a simulation to test the claim, and the results partly corrected him: oversampling sped convergence but hurt probability accuracy, while importance weighted oversampling kept most of the speed and the accuracy. The code was cross checked with AI, and he posted the corrected conclusion as an answer.
Had the AI move his Fastmail domain from Namecheap to Cloudflare in Chrome, handling the nameserver steps for him.
Hard drive prices pushed him to shrink his video library instead of buying more space. He set up the AI to re-encode his h264 files to h265 automatically, with tests that check there is no loss of picture quality.
He set a post up in an AI app and his small tool crier sent it at the set time to Mastodon, Bluesky and Nectvia. Nothing was running on his side when it went out.
Had an agent write an MCP for his SearXNG setup, then do comparison passes against server-side LLM web tools and tweak it; it works pretty well in his own search use.
He wanted the AI to compare pricing across the two data centers he uses. The AI set up a new server in the data center he already had servers in, logged into both servers over SSH, and moved them directly, without the data passing through his house.
Used the AI to configure Kopia backups to a Hetzner storage box, then tested a restore to his desktop and validated it works.
Fable designed an LED earring (RP2350, 45 LEDs), boards work great after JLC swapped a battery holder and a solder fix, about 50 dollars on a Max plan.
He has had to archive a whole radio station before. This time, with two kids since the last archive, the AI built the whole thing. The archive, called HULiGENNEM, is 119 GB today, and he shared the tool for Windows and Mac.
The AI diagnosed a long-standing 4K display issue and he now has a CLI tool that fixes it.
A young man (OUT OF OFFICE, 30K followers) photographed his wardrobe and fed the pieces to the AI before a dinner reservation. Nova chose a black henley and dark wide-leg jeans, cross-checked his calendar and noticed the reservation was outside so it advised layering a long-sleeve, then recommended loafers over sneakers plus a silver watch and bracelet.
Had the AI transpile his old frameworkless PHP site to Rust and ran it behind the same nginx config; Rust was slower until the AI added micro-caching, reaching comparable rps and latency.
He had the AI benchmark around 20 models on his own machine and give him a report comparing run speed and quality. After 7 hours of testing it said gpt-oss-20b was the best fit for his setup, and that is the one he chose.
Uses the AI on his phone to clone projects, build his features in, build the app and push it to his phone, usually not upstreaming.
Every idea is a real post from someone who tried it, summarized in our words, with a link to the original. App names are swapped for plain words.
