Because I wasn't familiar with it and others might be curious too: that prompt is available at https://cdn.openai.com/pdf/04d1d1e4-bc75-476a-97cf-49055cd98... and is just below 5 K…

The Art and Skill of Radio Telegraphy by N0HFF[1][2] is also an interesting read, and goes into a lot of the history. I recommend it if you want to know more on the subject. [1]: h…

As did OOO.

I agree; it's very pleasing to read.

No comment of value other than to say thank you for putting (and keeping) your art out there. Genuinely beautiful, some of it. And the generative towers gave me a chuckle; that was…

+1 for V3 support, and if there's anything I can do to help with V4 support, let me know. I've not got the most free time, but would be happy to contribute if possible.

https://safedep.io/miasma-worm-ai-coding-agent-config-inject... seems to describe the same symptoms, for what it's worth.

If you're saying it only impacts public repos, I don't think that's quite right. It appears to impact private ones as well. Source: first-hand experience. If you're claiming that t…

There's also Horde or Koboldai.net or Koboldai.com or whatever their project is named, if you want a community-driven version of this. You can play with it via a WebGUI at https://…

The ARRL has some good writing on RF exposure. Basically everything I've read comes down to treating radiated RF energy as thermal risk. So it's not magic stuff that will give you …

"Transferring one time digitally" DRM-free audio files is possible and above-board (i.e., you pay and the artist gets paid) through services like bandcamp.com and their ilk. Of cou…

Neat article. I'd love to know more about how candle-flicker LEDs are assembled, because that source of [apparent] randomness is very interesting to me. I'm not sure if it's an LFS…

Wow, what an incredible gift (and privilege) that will be! Receiving a box with a few Klein bottles from you has still been the best thing I've ever gotten in the mail. I just earl…

>turn around and Except that each of the parent's chat windows has zero context that the other window's request even exists, so from each window's point of view it's as if one pers…

Python script that Claude Code wrote and I tweaked for peeking at marked USB-C cables: https://github.com/nhecker/usb-e-marker Gist of random (human-written) power-related commands…

The terminating device(s) are the ones that do the flipping, not the cable. You can take a cable that works either way between two high-end device, and then connect it to at least …

Why the 10 MHz radio?

Openrouter already does this, unless I've misunderstood the premise.

On one hand, injuries from vehicular accidents in the roadway may decline to AVs being generally safer. On the other, intentional violence due to unrest and unhappy jobless in "the…

I can give a third vote to the rough comparison between a keyboard with brown switches, and a Model M. I've got both, and like both.

I can corroborate this finding -- I think the horn switch is just a logic-level digital switch going into one or more MCUs somewhere, subjected to all manner of latency and (probab…

Welp, this puts my https://gist.github.com/nhecker/8e850773ff229724ce361967cc22... to shame. I wonder about the battery SoC being reported with macpow; there are several different …

Thanks for the [1] link, I hadn't seen that before.

I can't find it immediately, but I've read about something even sneakier than this. A standard broadcast station was modified such that its carrier signal was modulated by a PSK si…

Very cool! This is fun to watch. Now I'm wondering how residential rooftop solar is accounted for... presumably there are houses in these grids which export solar electricity or of…
