LessonsWe stopped writing the code. Now we’re starting to stop checking it tooFirst we let AI fetch the answers, then write the code, and now we hand its work to a second AI to review. That last delegation is different from the other two, because checking was where a gap in your understanding used to become visible.
GeneralClaude is supposed to be smarter than ever. So why does it feel worse?Opus 5 and Sonnet 5 sit near the top of the rankings, and longtime users say working with them is exhausting. Both are true, and Anthropic wrote most of the complaints into the release notes as intended behavior.
NewsHow Claude's text watermark actually works, and why people are cancelingAnthropic explained the mechanism two weeks after switching it on. It only changes where a random number comes from, which kills the quality complaint. It also means the people angriest about it are the least marked.
TutorialsHow to write a great CLAUDE.md file (with examples)A CLAUDE.md is the highest-leverage file you can add to a Claude Code project, and most people either skip it or bloat it. Here's what to put in it, where to put it, how to write instructions Claude actually follows, and how to keep it lean.
GeneralThe next big AI business may be a tool that makes machine writing impossible to detectClaude now watermarks its text and detectors flag most of what gets posted. Into that sits an unbuilt business worth an absurd amount: a tool that writes in any specific human voice, undetectable, no watermark. Here's why it burns down the market it sells into.
GeneralIs the real reason AI companies are adding watermarks to keep AI content out of training data?Every Claude output since August 2 carries a hidden mark that survives copy-paste. The stated reason is transparency for users, who cannot detect it yet. Anthropic can.
ToolsClaude Code was miles ahead but Codex and Kimi caught upA year ago there was no argument about which coding agent to use. I've spent weeks on Codex and the newest open models, and the gap closed. The harness got copied, the models matched it, and the constant switching is doing the rest.
Build logsWhy you should put Cloudflare in front of your websiteCloudflare blocked 22,471 threats. Here's what's actually hitting a new site, and the setup step most people skip.
LessonsIs it ok to fully rely on Claude Code to launch a platform?Design, code, deploy and every fix after that, with no developer and no second pair of eyes. The answer is yes, with one condition that has nothing to do with how much code you can write.
GeneralHow Google killed the internetMaking websites used to be fun. Now it's keyword research, schema markup, E-E-A-T signals and a summary box, and every site in a niche ends up looking like every other one. Then the search traffic it was all built for started disappearing.
GeneralLinkedIn Added an AI Slop Button, So Should Everyone Else?LinkedIn now lets you report a post for seeming like AI slop, and the data explains why it needed to. It also explains why Reddit does not, which was not the answer I expected to find.
GeneralThese AI Are Getting Too Good at Hacking. Should We Be Worried?Two labs disclosed models breaking out of test environments in the space of two weeks. The attacks were boring, which is the part worth worrying about. What actually changed is the cost of running the dull stuff at scale.
