It's blog.jgc.org and you should read it if you like a mixture of electronics, programming, history of computing and just plain randomness.

More great on screen code moments (I haven't got round to Superman III, yet): https://behind-the-screens.tv But Superman III is not just REM statements.

Doesn't the flag button serve that purpose?

That's not a project that excites me but good luck with it.

Wonderful!

At the bottom he notes: "I’m sitting in the UK as I write this. Under UK law, I believe this should constitute fair dealing: the purpose is quotation for criticism and review, and this single screen capture is in no way an alternative to paying to see the original film. The film comes from the USA, and under USA law I think it similarly constitutes fair use: it’s for non-profit educational purposes, the amount of the full work used is extremely small, and the effect on the value of the full work negligible."

I took down my entire "Behind The Screens" YouTube channel and transferred it to my own site: https://behind-the-screens.tv because of copyright notices from YouTube that were heavily skewed towards the studios and I didn't have the energy to fight what was clearly fair use in my videos.

These are still heavily used at airports and the sound of the dot matrix printer going at the gate is usually a sign that boarding is starting soon.

I am an older, low-level developer!

Me and some other friends used laptops (think they were IBM ThinkPads), PCMCIA Ethernet adapters (maybe from Xircom?) and thin Ethernet (coax) to play multiplayer DOOM on a Reno Air or AA flight from San Jose to Austin once. I think we were using IPX for networking and we just strung coax between the seats.

Needless to say this was before 9/11 and the flight attendants took it in their stride.

I have a Flipper Zero and I've used it... occasionally. Like that one time controlling the Taylor Swift Eras tour wristbands: https://blog.jgc.org/2024/05/controlling-taylor-swift-eras-t... but it's mostly sat around being an odd device.

I duplicated a couple of RFID things, used the IR for some stuff, and once in a while used the radio receiver, but mostly it looks pretty.

I'm not sure what I'd do with a Flipper One, but I guess I've done a lot of things with Raspberry Pis so... maybe?

I had not thought about it that way and to be clear some of the parameters (such as the sizes you mention and also the row numbers in ELEMENTS) were found by a bit of experimentation. With the fundamental algorithm in place there was a bit of iteration to get something that looks good on screen (almost all the time).

The other thing was the title. The code originally could have had two letters (e.g. P and E in APERIODIC) joined at a vertex and it looked odd (it looked like the word was broken) so there's specific code to make sure that doesn't happen.

On that machine there's Claude's authentication for my account so I can run Claude on it, a public key so I can SSH to the box, and a private key for GitHub access.

And this is partly why my development machine is a Raspberry Pi that I can image any time by removing the SD card: https://blog.jgc.org/2026/04/raspberry-pi-as-isolated-ai-cod...

The code includes an ELEMENTS array with the layout of elements on the standard periodic table with H at the (1, 1) position. The tiles are laid out on the page and the code attempts to place the elements as close to the "standard" position (rectilinear) by calculating the Euclidean distance from the centroid of rhombi to the centre of the square that would be drawn for the element in the standard table.

So you've got 118 elements with ideal locations and a whole bunch of rhombi with known locations. The Euclidean distance (without bothering with the sqrt) is used as the "cost" function for the Hungarian algorithm (https://en.wikipedia.org/wiki/Hungarian_algorithm): the idea is to minimize the cost (distance from ideal) for each element.

You will sometimes see some gaps in the periodic table as this layout isn't "perfect" (in the sense of without isolated rhombi inside the table) and I did work on having a post-layout pass where these islands were identified and filled by moving adjacent rhombus assignments, but I wasn't happy with how this tended to break the layout of the periodic table (I was going for some visual "looks similar to the classic U shaped periodic table) and so decided to accept them.
