Obsidian Web Clipper now lets you manage highlights, and stays in Reader mode when you click links. It's such a pleasant way to browse the web. You can control the colors, fonts, and easily copy anything to Markdown.↗

Just shipped an update that allows Pi prompt templates (slash commands) to run any command or script *before* the LLM. The model is only brought in when you actually need reasoning: `handoff: never` → run, done. No LLM latency. `handoff: on-failure` → only ask the model if the c…↗

I know I’ve said this a lot, but I cannot emphasize enough that email will continue to become less deterministically reliable as a means for distributing your work; this is a huge part of why we got into the app and feed business! You can blame a few things (1/n):↗

Confirmed that Anthropic - as of now - has removed Claude Code from new Pro signups. This is what the pricing page looks like. Feels like Anthropic has the bet that those doing coding work will be willing and ready to pay at least $100/month, going forward.↗

Asking Claude Code to make an HTML visualizing its current context window is a pretty wild way to learn about how context window works↗

Claude Design surprised me. It's actually quite good. I hit some rough edges but I still think it is worth trying and thinking deeply about. Props to Anthropic, they cooked here.↗

Did a quick Pi extension that gives me /push. It synthesizes a user message, “Please push this worktree to GitHub main,” and synthesizes a Git Bash tool call for it. Then it lets Pi run that and gives the result back to the model.↗

I think 200k context window w/ good compaction is the sweet spot. Models claiming to have larger are rarely better at rembering important stuff from my experience↗

It's a terrible idea to build a ~10 year VC fund strategy as a reaction to temporary market conditions. Yes; bifurcation, concentration, consensus, consolidation, stagnation... All valid observations, but they do not change the persistent reality of VC. - Greatness is idiosync…↗

Monologue Notes is here. Dictation is for when you know where the words are going. A Slack message. An email. A prompt to Claude. But some of your best thinking doesn’t have a destination yet. It happens on walks, on calls, in 30-minute brain dumps, and in half-formed ideas you…↗
