1. 10 Months of Bank Statements, $0 Uncategorized: Grok Bot Built a Small Business Accounting Department in One Evening

A business owner stopped paying a leased accountant and asked Grok Bot to build a real accounting setup instead. In one evening it reconciled 10 months of bank statements, matched every client payment to its invoice, closed the books to $0 uncategorized, then set up a separate bookkeeper bot to keep them that way.

2. 12 Cores at 112°C: Claude Caught a Hidden Crypto Miner While Building a Mac Temperature App

A Mac owner asked Claude to build a simple temperature monitor app. While checking sensor accuracy, Claude spotted a miner called xmrig using about 1175% CPU (roughly 12 cores) with the CPU peaking at 112°C. It traced the miner to /tmp, found a random-named startup item that had been there since Aug 29, and stopped to ask before killing or removing anything.

3. Set Up a New AI Model on 2 Home Servers From Bed: Grok Bot Did It From One X Link

A home-lab owner saw a post with a setup recipe for running a new DeepSeek model across two NVIDIA DGX Spark machines. Still in bed, they sent Grok Bot the post link and asked it to download the model and set up the recipe. Grok Bot wasn't installed on the Sparks, but they were on the same network as its computer, and it had everything ready to test by the time they got up.

4. 10 Years Without a Way to Talk: A Non-Coder Used Claude Code to Build Their Brother a Switch-Controlled Hub

Ben is nonspeaking and quadriplegic and went nearly 10 years with only yes/no head turns to communicate. His sibling, who had never programmed, described what Ben needed in plain language and used Claude Code to build a free browser hub he runs with two switches: a keyboard, phrase boards, text messaging (his first ever), web search, picking any streaming show, and dozens of games. A Claude-powered tool suggests replies he can pick so he can join conversations.

5. 4.9x Faster, Still Bit-Exact: Claude Ported Super Mario 64's Physics to a Game Boy Advance

A developer steered but wrote no code while Claude ported Super Mario 64's movement and collision code to the Game Boy Advance, a 16.8 MHz chip with no floating-point unit. Mario's state matches the original game bit for bit on every test frame, two rounds of optimization made it 4.9x faster on average, and the free demo runs 4 levels at 30 fps on about 98% of frames.

12 Cores at 112°C: Claude Caught a Hidden Crypto Miner While Building a Mac Temperature App

Help me check if my computer is secretly running a crypto miner or other malware. I'm not technical, so use plain language. Go one step at a time and wait for my answer before the next one: 1) Ask if I'm on Mac or Windows. 2) Walk me through opening Activity Monitor (Mac) or Task Manager (Windows) and sorting by CPU. 3) Ask me to close my apps, wait one minute, then send you a screenshot of the list. 4) Walk me through checking what starts up automatically, and ask for a screenshot. 5) Tell me which items look normal and which look suspicious, and why. Don't delete or kill anything yourself. If something looks bad, tell me to change my important passwords from a different device first.
