THE CONDUCTOR REWRITE: WHAT THEY CHANGED TO MAKE IT FAST

Conductor is a local-first React app wrapped in Tauri with SQLite as its source of truth, and it was rebuilt to be twice as fast. After shimming Tauri's invoke() bridge to profile in Chrome (since React DevTools can't run in WebKit), the fixes were migrating to TanStack Router for stable references, virtualizing the chat with react-virtuoso plus React.memo, switching agent processes to Bun, and moving the git checkpoint off the critical path.

MY AUTOMATED DOUBT DEVELOPMENT PROCESS

"Automated doubt" uses specialized subagents to critique artifacts from multiple technical perspectives. This workflow begins by front-loading scrutiny during the design stage, where agents identify hidden assumptions and architectural gaps within technical specifications. Once implementation is underway, a suite of post-development agents audits the codebase for security vulnerabilities, type safety, and logic errors to make sure the output meets high engineering standards.

DID CLAUDE INCREASE BUGS IN RSYNC?

Statistical analysis of thirty-six rsync releases showed that software versions assisted by Claude AI show no real increase in bugs compared to historical human-authored releases. Using severity-weighted bug metrics and exact permutation tests, the data shows that these AI-influenced releases fall within the normal historical distribution rather than appearing as statistical outliers.

I BUILT A VULNERABLE APP AND SPENT $1,500 SEEING IF LLMS COULD HACK IT

An experiment tested the ability of various LLMs to identify and exploit security vulnerabilities within a custom-built React Native and Python application. After feeding models an APK and a challenge description, success rates were evaluated. GPT-5.5 emerged as the most effective tool for this specific task.

"MAYBE LATER" WAS A FEATURE

Choosing not to build unnecessary features is a development strategy that prevents the accumulation of technical debt, a risk that is even more prominent since it's so easy now to use AI to generate code.
