dmd··on If you put Apple icons in reverse it looks like someone getting good at design

For a moment I thought you meant you could say "command space" to Siri on iOS and was prepared to have my mind blown.

dmd··on An Elizabethan mansion's secrets for staying warm

What does 'lifetime' mean? Mine are nearly all original.

Build, no. But here in New England (Boston suburbs) even double-pane windows are still quite rare, because most houses are ~100 years old or more.

Or IIIF.

dmd··on Show HN: OpenWork – An open-source alternative to Claude Cowork

How much more open do you want it to be? It’s MIT licensed.

They used to be very responsive. “Multiple locations are on the way” (bottom left corner) has been like that for years now.

Still the best of all the weather apps though.

dmd··on Show HN: Website that plays the lottery every second

If $DEITY wants me to win, the winning lottery ticket will be dropped by someone and it’ll blow into my car and get lodged onto the dashboard.

dmd··on Bluetooth Headphone Jacking: A Key to Your Phone [video]

I know someone who spent upwards of $10k on a single 3-foot HDMI cable that was 'infused with Peruvian copper'. He says it makes the colors "more true".

What does audio have to do with this post?

dmd··on Scientists unlock brain's natural clean-up system for new treatments for stroke

supposing you brought the light inside the body, either through the skin or some other way

dmd··on 2025: The Year in LLMs

Yes, that is the analogy I am making. People argued that bicycles (a tool for humans to use) could not possibly work - even as people were successfully using them.

dmd··on 2025: The Year in LLMs

People denied that bicycles could possibly balance even as others happily pedaled by. This is the same thing.

dmd··on Show HN: Z80-μLM, a 'Conversational AI' That Fits in 40KB

https://3e.org/private/z80ulmweb/

It's just one-shot AI slop - literally, the prompt was 'make a web based version of [github url of this project]' and it spat this out. It appears to work fine.

I'll keep it up for a couple of months and then it'll be auto-deleted, no sense in keeping it around longer than that.

dmd··on Ask HN: What did you read in 2025?

It just felt more coherent and tight to me.

dmd··on Ask HN: What did you read in 2025?

Here you go! https://3e.org/books/

I read ~80-100 books a year, mostly SF/F.

dmd··on NYC phone ban reveals some students can't read clocks

50 years from now? this is already absolutely a thing.

dmd··on Rob Pike goes nuclear over GenAI

Er... yes? Obviously? What are you even asking?

dmd··on Show HN: Vibium – Browser automation for AI and humans, by Selenium's creator

Almost nothing I do has to do with what users actually see though. It’s all things like “why didn’t the SSO flow work”.

dmd··on Show HN: Vibium – Browser automation for AI and humans, by Selenium's creator

Thanks. I would love to understand what people are doing with Playwright that doesn't involve those things. I really can't recall ever using it where that wasn't what I was doing. I use it letting Claude fix things. You can't fix what you can't see! What else are people using it for? Obviously there must be a (very popular!) use case for "just clicking", but I can't seem to imagine it.

dmd··on Show HN: Vibium – Browser automation for AI and humans, by Selenium's creator

Does it allow you to inject js, modify the DOM, and most crucially monitor/modify network requests? I do those things in probably 95-99% of the time I reach for playwright mcp in claude, and from the "For Agents" part of the README, it seems like all this can do is click/type/screenshot?

dmd··on Fabrice Bellard Releases MicroQuickJS

Wow. That's way higher than I thought. Huh!

dmd··on Fabrice Bellard Releases MicroQuickJS

Just like all those normal people want rid of their bloated day-to-day monster of a web and therefore go and do something like, say, install an ad blocker?

Oh right. 99% of people don't do even that, much less switch their life over to entirely new websites.

dmd··on Programming languages used for music

And at least 5 times a year someone designs a new one where it is painfully obvious that they're almost entirely unaware that anyone has ever designed one before - or if you're very lucky, maybe they've heard of ABC.

dmd··on Danish postal service to stop delivering letters

Hours, for me.

dmd··on CO2 batteries that store grid energy take off globally

It has nothing whatsoever to do with sinking CO2.

dmd··on Show HN: WalletWallet – create Apple passes from anything

That would be pretty great. I have half a dozen codabar-based cards.

dmd··on Show HN: WalletWallet – create Apple passes from anything

Could you add Codabar?

edit: oh, I guess you can't, because Apple Wallet doesn't support it.

dmd··on Skills Officially Comes to Codex

A very particular set of skills.
