Boston Dynamics is better than Tesla but only just sort of accomplishing moves in the shop that Unitree's robots can apparently do reliably in a live choreographed performance. www.youtube.com/watch?v=UNor...

I don't know why this robot performance -- casually dropped into the CMG Spring Festival Gala -- isn't getting more attention. Stunning advancement in robot technology. Feels like Unitree suddenly passed and then lapped Boston Dynamics in the past year? And lol@Tesla. www.youtube.com/watch?v=mUml...

I came to Minneapolis to report on what's going on, and one of the main questions I showed up with is "just what is the scale of the resistance?" After all, we're all used to the news calling Portland a "war zone" or whatever when it's just some protests in one part of town.

You probably know more people than you think who have a drink every night to unwind, but don't really talk about it. Until fairly recently it was actually recommended as healthy. (Turns out the supporting studies were correlation not causation -- wealthy people can afford more booze.)

Hmm, an average 5% ABV pint is actually 2 American "drinks" or like 3.5 British "alcohol units". Unclear what unit they are using but possible that this just means "3 pints a week".

And yeah the people on the high end really skew the average.

Suggesting nearby food would have been a fine response. Or saying nothing would have been fine (the normal web results had what I wanted).

What I don't like here is the tone, telling me my query is wrong, lecturing me, and generally talking down. Gemini does this a lot though.

I was looking for a sound clip from the 1983 arcade game, Sinistar, and instead I got... whatever this is.

Would greatly prefer if all the people I follow on X would just switch over here!

Whelp. I'm locked out of X because it insists I re-enroll my security key (which I haven't used in years, I always use the authenticator app), and when I try to do that, it just loops back and prompts me to do it again. Great.

Yep! Note you have to use the websocket transport for that, and once the websocket disconnects you can no longer call the target.

Where, to be clear, "they" is Theo and his team, not me or Cloudflare. But indeed, "vanilla" was much faster than any framework.

15.10.2025 21:19 πŸ‘ 2 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

Something like that. Not sure if it scales linearly.

15.10.2025 01:50 πŸ‘ 1 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

The vanilla case actually generates 3x more HTML compared to next.js because it was too fast to measure reliably otherwise.

The SvelteKit case is supposed to do the same work as the next.js case though.

The react case produces less HTML than the others, dunno why.

Correction: I'm told that the SvelteKit benchmark does actually perform the same work as next.js. The "vanilla" benchmark, though, generates like 3x the HTML.

The benchmark cases are not comparable to each other, they all do different stuff.

The benchmarks render 5MB to 15MB of HTML. They are not normal workloads.

Those benchmarks from @t3.gg revealed some interesting issues in Workers. Happy to say it's all fixed now, save for some lingering next.js-specific stuff we're continuing to work on. Thanks for the reproducible test cases, @t3.gg.

Personally, I don't use the "for you" tab, I only use "following", and I basically don't see any politics at all. (I tend to unfollow anyone who posts politics TBH.)

I was actually doing that even before the acquisition, so didn't see much change after.

Exactly as I remember it, in excruciating detail. Why does my brain continue to store this while forgetting people's names?
