The sky is solid uniform white today! It's like they forgot to finish rendering the screen in a game.

Soooo... I had a weird dream about a silly made up puzzle then woke at 5am trying to think of ways to solve it. And have now spent 4hrs on it.
How's your Saturday?

I think watching the World Cup Chess this year is the first time I've remembered the passionate enthusiasm sports fans have about about whatever their game is since maybe the 1990 rugby 7s.
It's so crazy all over the place. So fun!

What's the fastest thing humans' have ever made? Is it Voyager? It's moving at such a small fraction of the speed of light.
I guess we've made torches that make photons ...that move at the speed of light. But that feels like cheating.

Are you telling me the one friggin night that I, a resident of the desert that always has clear skys, has a solar flare and the northern lights in the sky happens to happen - I also have clouds and rain?!?

Nothing i have is planned. And a lot is coming. Things are going to be messy.

Ok yes since I got apparently recognized - I was at IIW tonight. That still doesn't make Identity cool.

Every time I think I have a handle on how awesome @racket-lang.org is, I accidentally come across something they did a lustrum ago that is even more awesome.
I think it's going to take all evening to digest how cool this is: www.youtube.com/watch?v=j5Ha...

I wonder how many people knew Dumbledore liked candy enough to choose it for his passwords. Near as I can tell there's ~150 candy mentioned in @harrypotter.social - that's about 8 bits. Dumbledore talks about far fewer - about 3bits.

I wish there was a post from Google that would explain to me, a mildly technical person, why they wrecked chromecast - was it a legal issue that forced their hand, some technical problem, incompetence - I expected it from Google but am sad to have been so right.

Every once in a while you have to ask yourself, given the nonsense, why am I here and not there.

I worry I'm just contrarian.
I worried about AGI a decade ago & now find myself groaning internally about *how* people complain about it.
Reminds me adults complaining "there's data" that "comics & calculators are making kids dumber".
At least I've learnt to be mostly quiet.

I am going to hate MCP when I look at it, aren't I? I mean - I haven't and I will. But I just know I will hate it.

I was promised a storm.
I got merely wet...as an islander, SF's understanding of a "downpour" continues to surprise me two decades in.
It's too wet to be outside.
But it's also not wet enough to be outside.

Yeah it hallucinates.
But instead of complaining, what if realized that was a feature and find use cases when a little hallucination is not merely desirable but phenomenal?

I miss the simplicity of old Browsershots - "here's a url, give me a grid of screenshots". I had a tiny template which changed bgcolor of the page based on pass/fail. You could eyeball 100s of browser/version/OS at a glance.
New "dashboards" comparatively suck.

A tshirt has 4 holes - when I turn it inside out, I sometimes pause in wonderment that no matter which one I use, the outcome is the same
When you turn a tshirt inside out, which one do you use most?
* Any (why think about it?)
* Bottom (I'm normal!)
* Neck (I'm a rebel!)
* Only sleeves (my peeps!)

It's hard to convey how frustrating it is seeing people take away the wrong lesson from the npm worm & knowing it'll harden (heh) the wrong approach to addressing issues like it.
And to anyone wanting to ask me what I am doing about it - sadly nothing - I'm busy elsewhere.

The number of times I hear about a soon to be amazingly successful company who "merely" recreated anycast & DNS but badly is too damn high.
It would be fine if all they did was give it some much needed UX sugar but when they break its nice properties is when it hurts my soul.

It took me a second to work out the whacky way PetSmart sorts fish tank sizes - but that there is only 1 30G & over tank but 11 40-54G tanks...seems wrong.
