    FOSS source is here.

    The second “S” in “FOSS” is “software”. You did not publish software, just its output: bitmap assets needed to print the stickers. Thanks for CC-licensing your creative work but source would mean showing what’s under the hood. We don’t know how you sourced the images used in each triangular tile: generated to best correspond with AI? Matching pieces from Wikimedia Commons photos?

    Edit: Look closely at Arch for example. It’s clearly just the logo placed in a hexagon, approximated by a mosaic of 24 triangles with AI images of differing quality. Is that snow or whipped cream? How can PCB traces be as blurry as watercolor? At least they’re topical: for Arch the prompt was probably “mountain OR architecture OR arch OR technology”.

    Presumably, the process for each tile is this:

    1. you make some direct artistic choices to create the base image (place the logo in a hexagon, choose a background color, add a border)
    2. you make some indirect artistic choices: pick keywords/themes for the AI to use
    3. you use a script to divide the hexagon into 24 triangles (presumably with “overscan”)
    4. you use generative AI to stylize the triangles’ bitmaps according to thw keywords, perhaps regenerating bad output
    5. you use a script to reassemble the image

    To consider this open source, I’d expect you to at least post the scripts you used in steps 3 and 5. To consider this good open source, it should contain a guide detailing this process, best with examples. I’d expect the AI part will be “bring your own model” but you could tell which one you used and its settings.

    The idea is creative and “human” enough for me not to condemn it. “FOSS” or not though, you should disclose use of AI, especially since you’re selling the printed stickers.

    Edit: yup, it’s made of AI images


    This is not an AI-generated pic, it’s a photo taken with a real camera. The logos, however, are hexagons divided into 24 triangles each, and these triangles contain often thematically related (e. g. lions for Brave) photos or photorealistic AI images (the info I found online does not state either way) cropped to best correspond to what the triangle would contain if it just had the original logo. Basically, that corner of the whale surrounded by white was taken from a face photo (or AI pic).





  • Steam engine pistons also move back and forth less than a meter at a time, and still could push trains a million kilometers in the forward direction. It’s that they’re pushing right while moving right and left when moving left. That’s like when AC current and voltage are in phase, delivering positive net power. Meanwhile, something that pulls left when moving right is consuming power.





  • You are correct, that was a mistake.

    However, although symbols of units named after scientists (V, A, W, C, J, Ω, H, F, T, Hz, S, K, N, Pa, Bq, R, Ci) are uppercase, they are lowercase when written out (volt, amp(ère), watt, coulomb, joule, ohm, henry, farad, tesla, hertz, siemens, kelvin, newton, pascal, becquerel, roentgen, curie) to differentiate them from the surnames. Also be careful with degrees (Celsius, Fahrenheit, Rankine, Réaumur…) and grams (g, not G or gr), unrelated to the bacteria-ranking Christian Gram. And yes, the l/L debate is why the Claude Litre hoax was created. (In Unicode-capable applications I use 𝑙 BTW)


  • The electrons don’t move very quickly either. Like, a sluggish one millimeter per second is more current density than most metal conductors can handle without melting. Thankfully, there’s lots of mobile electrons carrying charge (coulombs) so that’s a lot of current. “Electricity” only travels near the speed of light because voltage is like a force sending waves through the electric field (simplified). And it’s instantaneous current (amps = joules edit: coulombs / second) times voltage (electric field potential difference in volts = joules per coulomb) that delivers power.

    Simplifying to a single harmonic (pure 50Hz/60Hz sine voltage source and a passive, linear RLC load), you need not only multiply the voltage’s and current’s effective amplitude (that gets you apparent power in VA, voltamps) but also their power factor or cos φ (the cosine of phase beetween them) to get power in W (joules per second). If the cosine is one, it’s a purely resistive ® load (like a heater) with a phase difference of 0°. If the PF is zero, it’s a purely reactive (L/C) load (a freewheeling synchronous motor is much like that) with a current phase of ∓90° and no power is consumed overall. If the cosine is negative, power is actually being generated by the device you’re measuring (for instance, old elevators and escalators with synchronous motors are actually delivering power into mains when enough people are travelling down).
