Still not a great idea. You leave yourself vulnerable to the real people in your life who have physical access to that paper.
Nothing beats a real password manager. More secure and convenient.

This honestly sounds like a great use case for an evolutionary algorithm. Especially if you're not interested in perfection.

- Generate neighbor-finding functions
- Run on a bunch of long test sequences
- Slightly modify the good functions
- Repeat

I would love to see what this looks like on hair geometry

You do not, under any circumstances, "gotta hand it to them"

A Melitta funnel and a kettle is like $30. Smaller, easier to clean, and you can use a kettle for other things.

Target has paying customers where a boycott could be effective.

Twitter won't let you move to a different app with different ToS.

Going right is when you don't enforce unenforceable rules? Just block the assholes. It's liberal as fuck. Bluesky doesn't aim to build/prune your network for you.

I had the same thought before I started used a mac. Then I got a Mac and it just feels more natural. Browser, IDE, and Slack are all full screen and everything doesn't need to be that important.

I think Windows' square corners and tall menu bars feel too bulky to justify being smaller.

A few of those frequencies fade out after the explosion. I assume it's some machine that shut down either directly from the explosion or an automatic safety thing. That's really interesting to see

I think you two should collaborate and publish an unofficial API that makes atproto embeds easy. Bluesky/leaflet should provide easy, ways to respectfully embed posts/leaflets elsewhere. Atproto apps would feel more connected.

You shouldn't have to rewrite their already fine renderers.

I'm so glad my parents let me grow my hair out when I decided to. I wish they pushed me to figure out what I liked sooner, but when I finally knew what I wanted they let me have it.

Starbucks is closing stores and cutting 900 jobs in a restructuring move.

1,100 jobs were slashed earlier this year.

Reminder that Starbucks’ CEO made 6,666x more than the company's median employee in 2024.

This was the widest CEO-to-Worker pay gap in the entire S&P 500.

The solution to climate change needs to be contagious. A country committed to a net 0 plan asap should have such obvious benefits that other countries would feel stupid to not do the same.

The cost is great, the benefits are not obvious, and it's hard to feel hopeful for future generations.

I understand that live tech demos are hard.

But when the tech is an unpredictable, unreliable, hallucination machine, and you rely on it to be grounded and predictable, maybe it's just a bad product.

"It's all good." It's very clearly not.

Same with booting up my PC. It takes tens of seconds for it to get to the "press F11 to enter UEFI" screen and then it's immediately gone and I missed the window and have to try again. I have fast hardware but it's worth nothing if software is slow

Of course, these algorithms are constrained in other ways-random generators simply aren't good enough to do what people can do with an actual deck. But even the most skillful human dealer cannot provide a perfect hand every time.

This article seems pretty sloppy. Pseudorandom number generators on modern computers are way more random than humans. That ability can be trivially extended to shuffling a deck.

Human shufflers are the ones that are constrained.

Open source browsers and plugin frameworks are the only way out of this mess. I wish they would hurry up.

I made a simulator to explore the space of double pendulums! It runs in your browser with WebGPU, and it's very fast!

I wrote a little about it here: alex.leaflet.pub/3lxizbtwyg22d

If only we had a government that bothered to govern. It sucks that plenty of people are capable of thinking ahead and want to minimize damage, but apparently funding the thinkers ahead with taxes is an insane idea.

AI chatbots are the obvious products to build with LLMs but it's just truly irresponsible. Coding assistant, fancy auto complete, search assistant, fine whatever.

But an interface designed to sound like an authoritative, informed, person with chat bubbles is dangerous.

I always regret putting comments at the end of a line of code rather than on its own line above, and I do it ALL the time anyway.

Learning C early on made me overprioritize code golf and I hate it. Err on the side of verbosity. Newlines cost nothing. Abbreviations suck. Comments are rad. </mantras>

Loving this so far. I think this is the scene in Star Trek he was talking about. It honestly still looks great in 2025.

Sure, I don't think it really matters what the offset is, as long as it's the same for everyone. I just like UTC because I'm a programmer.

What's the problem with that though? The number being different on the clock at sunrise for someone on the other side of the country is not worth the trouble of time zones.

Abolish DST and timezones! Life would be easier if we all used UTC
