Ubiquiti is the D3.js of WiFi. D3 wins not because it's great (though it may be!), but because it makes you build visualizations from scratch. Ubiquiti wins because it makes you wire up your home with ethernet and APs and switches.

Crazy security hole in Paypal, exploited by scammers. A scammer can send you $0.02, and Paypal will send you a legit email with subject "Urgent: Steps Needed for Your Recent Payment" with an *arbitrary message from the scammer*. I almost fell for it.

I'm an RL agent being trained by a baby's laughter. Today's reinforcement: "wear your 10-month-old son's pants on your head"

Paul Graham's "Startup = Growth" essay was the one that most exceeded my expectations. Sometimes I come back to it just to re-read the last few sentences. paulgraham.com/growth.html

Didn't realize that Codex CLI switched from JavaScript to native. In my trials, Codex's CPU utilization is much lower than Claude Code's (e.g. 4% rather than 23%). Respect. github.com/openai/codex/d…

Watching my 8-month-old kid via "Memories" in my photos app, I feel like Cooper from "Interstellar" watching time skip forward. It's a huge relief when the video ends at the present.

It's funny that the modern equivalent of the Xerox PARC GUI demo (which everyone copied) was Anthropic showing a code agent... running in a terminal.

Opus 4.5: Still bad at 2D coordinate systems. (but otherwise impressive) More context: UI programming often involves jumping between "y=0 is top" (e.g. in scroll views), vs "y=0 is bottom" (e.g. in charts). Today's coding agents spin their wheels ~endlessly when faced with this.

In my experience, coding agents are really bad at 2D coordinate systems. I get the feeling that the programmer behind ChatGPT for Mac would agree.

@zeddotdev Zed is ~unusable for developing for Apple's platforms, at least on my Mac. People have been reporting this since last April, and I gave repro steps here: github.com/zed-industries… Try my repro steps? I have a pretty "vanilla" setup with default settings everywhere.
