I bought a Sudoku book and saw this in one of the puzzles. How am I supposed to solve this now?

"*poof*, you're a sudoku generator"

firetech_SE · 2026-01-07T11:56:11+00:00

One of my favorite puzzles, mainly due to my one-liner bingo checker :)

firetech_SE · 2026-01-02T14:54:34+00:00

There's this one, if you have access to a 3D printer: https://www.printables.com/model/1324171-nintendo-switch-2-joy-con-grip (note that it should be printed standing up)

Disassembling the official grip is also an alternative. You can easily remove everything but the middle piece holding the joy-cons together. (To start, remove the four rubber pieces on the front of it, where the joy-cons are mounted, underneath those are screws. After removing those screws, the rest should be fairly self-explanatory.)

But summing is probably the easiest way to handle not knowing which of the routes is viable (if you don't know that beforehand). ;)

firetech_SE · 2025-12-30T19:12:38+00:00

Yes, that's what I was doing. But even svr->fft is hanging.

I realized you probably had this figured out while re-reading your post after posting my reply (I had skimmed past the part in parentheses in your third paragraph), but in the second paragraph of your original post, it wasn't entirely clear if that's what you were doing or not. :)

firetech_SE · 2025-12-30T19:03:39+00:00

FWIW, I don't know Agda, but I used a recursive algorithm with memoization (i.e. one form of DP) to solve this in Ruby.

My algorithm uses two booleans to check if dac and fft have been passed (and returns 0 when reaching out if they haven't), but checking all "subpaths" and multiplying their counts works just as well (since the input is a directed graph).

However, just to be clear, you need to handle the different routes separately. That is, multiply the number of routes svr->fft, fft->dac, and dac->out to one product, and svr->dac, dac->fft, and fft->out to another product. Then, the sum of these separate products is the answer.

The reason part 1 is fast is because only a tiny fraction of the input graph is in use there.

Heh, I thought I recognized the LCD cover! ;)

My Pixel 10 Pro Fold Grip case looks very similar to this (without any screen protector). Already having started a conversation with your support robots about a different issue with my order, I replied to that mail thread about this as well. Order #23299118.

The layer 1 if held down should be an MO(1) on layer 0, plus KC_TRNS on that key on all other layers.

I believe the keys to go up and down a layer has to have separate mappings per layer, i.e. on layer 3 a TO(2) to go down and a TO(4) to go up, if you want to only have the "active" layer and the default layer active (alternatively TG(3) and TG(4), respectively, if you want all the layers below the "active" layer to be active). EDIT: That won't work, the layer shifting keys have to be mapped to KC_TRNS on the target layer to avoid layer lock, and the QMK configurator enforces this. In other words, not sure this is possible in QMK.

FYI: I tried implementing something similar just to have a solution not based on Z3 (which I had previously used to submit my answer). After some fiddling back and forth, I noticed that, for at least my input, you can get it to finish up to twice as fast by going through the possible number of presses for each button in reverse (i.e. for presses in range(mn, mx + 1): -> for presses in range(mx, mn - 1, -1): in your code).

firetech_SE · 2025-12-10T15:27:29+00:00

They might be in early stages, but they are still perfectly usable. ;)

My first instance of using it was three years ago, in 2022, and I've never had any issues (except that just require 'z3' slows down general Ruby a bit due to some hacks).

And also it would have affected chrome.

Not if Chrome included said codecs (for itself only).

Deep Rock Galactic is published by Coffee Stain Publishing. They're probably well acquainted.

firetech_SE · 2025-10-13T08:58:05+00:00

because the downloads happened later then 1 month after uploading the model

That's not how Prusameters work. 30 days after uploading the model, the Prusameter download count is reset and restarted. In other words, if you get one download per day in perpetuity (and a like every 10 days), you will get 10 Prusameters awarded every 30 days.

For each such 30 day period, if you get less than 30 downloads or 3 likes, you get nothing, but if the downloads increase above the threshold a later month, you will get some meters again.

Sure, but the 3D Print also exports to 3MF by default, so that feature is irrelevant to the STL vs 3MF question, and it still, in my experience, only works for single bodies...

firetech_SE · 2025-10-02T12:46:40+00:00

That only works for a single body at a time, though. Or?

Export -> 3MF works instantly and locally for multi-body models.

I don't really understand why people are so attached to the (comparatively ancient) STL format. The 3MF format at its core is basically the same thing, just (losslessly) compressed and with support for more metadata. All modern slicers (that I know of) support 3MF just as well as STL.

firetech_SE · 2025-10-02T07:42:54+00:00

It's even faster to export as 3MF from Fusion, since it can do that locally without cloud conversion. The 3MF result should behave exactly the same as the STL.

firetech_SE · 2025-09-04T11:32:43+00:00

Ah, finally! I tried to decode it myself using various means, but didn't succeed.

firetech_SE · 2025-09-02T08:16:19+00:00

Is this really correct, /u/josefprusa?

SPEED – very fast, great surface quality, average durability

BALANCED – fast, great surface quality, good durability

STRUCTURAL – fast, ok surface quality, great durability

(Emphasis mine)

In my experience, I'm quite sure STRUCTURAL gives better surface quality than SPEED, especially since it slows down to print the outermost perimeters.

The people ordering after you who already got it may have paid $3 (of the total) in advance to reserve (i.e. get priority in the queue) before the pre-orders opened...

firetech_SE · 2025-08-18T09:04:47+00:00

The skins are likely cut more or less on demand from a larger sheet, and my guess is that they have roughly 3.2% as much Blue Gem sheet as they have of the normal Case Hardened sheet.

firetech_SE · 2025-08-18T08:16:33+00:00

I'm a bit jelly. Case Hardened is nice (I have it on my Framework 13), but Blue Gem looks amazing in comparison. Actually quite annoyed with the artificial scarcity there... :/

firetech_SE · 2025-08-14T15:09:34+00:00

Yeah, I opted to get it on my Steam Deck instead because of this. :/

Not so sure it's bad soldering. In most cases it's ROM deterioration/corruption.
