I post-trained Qwen3-Coder to fix bugs using an actual debugger. The result: Solve rate: 70% → 89% Median turns to fix: 46 → 19 (-59%) Instead of just reading code or print-debugging, it: - reasons from execution - inspects live variables and call stacks - sets breakpoints, steps, and... show more

here's me using debug mode to fix a small bug in an swift app i just built issue was the initial characters were cut off when typing it out, so i had cursor 1. instrument the code 2. ask me to reproduce the issue 3. read the debug logs 4. implement the fix 5. ask me to reproduce to verify the fix using runtime context, cursor managed to fix it first try! team is using this very frequently, and highly recommend /debug mode for gnarly bugs

🤯 Wow! In one prompt Qwen3-Coder-Next generated a fully working flappy birds game in HTML. (0:05) Claude Code with Qwen3-Coder-Next (0:26) Shows the game running Run it fully locally: ollama pull qwen3-coder-next Ollama's cloud if you can't run it locally: ollama pull qwen3-coder-next:cloud Try launching it with Claude Code using ollama launch (link to play 🧵) So cool!

The 2-Second Lean principle is a foundation for our continuous improvement. Every year, we challenge teams to innovate with three simple steps: fix what bugs you; take a video; highlight it! An Edmonton team built a collapsible print table to move it through stairwells.

here's my hyperdev-1 setup, an elite American software developer agent (proudly running in Texas!): - rented a H100 - installed Claude Code - used it to install Qwen3-Coder-480B - and created an agent in Claude which uses this local 480B model .. connected to Github, Vercel, few MCPs.. all of this together generated and deployed the below websites - which showcases quality comparison between Qwen3-Coder-7B and the 480B, all run locally; and also the detailed installation instructions for the 480B (which was a pain to install and took many iterations) "You are an elite software developer with decades of experience across multiple programming languages, frameworks, and architectural patterns. You leverage the advanced capabilities of the Qwen3-Coder-480B model to write exceptional code that exemplifies industry best practices.."

Claude Code can test and fix your app across multiple iOS simulators. 20 minutes. No coding, no Xcode, no manual steps. You just need to give it the right tools.

I made this site entirely in Figma using Locofy.ai Responsive layout, breakpoints, pages, animations. The code is near perfect and exportable to React w/ styles, components and variables. For simple sites like portfolios and landing pages, you can do everything in Figma.

I built an open source data analyst agent! Upload any CSV, ask a question, and get it answered with statistics or a nice chart. Launching in 24 hours. 100% free & open source. Under the hood, here's how it works: 1. User uploads a CSV and asks a question. 2. The app uses Together Code Interpreter to spin up a VM and uploads the CSV onto it. 3. I have an LLM (Qwen 3 Coder) write code to interpret the CSV using `pandas`, then solve the question the user asked. 4. Together Code Interpreter runs the code in a secure environment & returns a result. These results can be text (some kind of stats analysis) or a chart.

Grok Build tip of the day: check your work! Just like you would check your work after writing code, use /check-work to have a subagent check on Grok’s code. It will look at the repo, trace alternative code paths, and fix bugs before reporting back to Grok what it found.

Californians are tired of candidates describing how unaffordable it is to live here. I'm the candidate with actual plans to fix it.
