heres a nice picture of the real part of the linear operator for fft * (linear op for x * a mod n) * fft done in matrix form. the basic schtick behind the quantum poo poo i'm working on is to apply this operator without actually instantiating it or having any qc hardware, by a giant pile of vicious weird little tricks. the singular linear op works, this is exponential instantiation but the operator application works (separately from the image, in polytime wrt cardinality of what the 'propositional bits'). if i can get the battery of x * a mod n dealios backing shor's to work and like 5 other things go right its doom time center antiidentity portion is capped because it fucks up the colors otherwise. but its real purty bob dobbs is dead fucked around with this message at 17:47 on Feb 18, 2024 |

well the tiny station isn’t going to shove itself toward the shuttle it has only enough fuel for station keeping, not maneuvering, it needs to remain in as close to an ideal orbit as possible to avoid wasting fuel the shuttle can carry enough thruster fuel for maneuvering to the station (and handling stationkeeping while it’s docked)

will you have capsules and cargo modules so the player can make x*shuttle vs n*capsule + m*cargo trade offs like maybe it takes longer to build a station with capsule + cargo but you can launch sooner and more often but that means fuel costs are higher and failure more likely, while construction costs are higher for the shuttle and you can’t launch as often but that also means you don’t use quite as much fuel and failure likelihood per launch is lower (but correspondingly more catastrophic) dunno just a random thought, thanks saliva

something like that! I have some complicated logistics ideas that are hard to articulate while phoneposting. short version is you’re actually managing multiple space agencies, each one makes different stuff and has different strengths and weaknesses, and limited capacity. I’m still working a lot of it out

They made quite a lot of those capsules, right?"  Both cheaper than I'd expect but still well beyond the buy it for the hell of it zone even if one was available. Someone in 2018 also got one for $700, the lucky dog.

that clock is super neat - I'd seen that channel's teardown/repair of one of the newer clocks, but not that one  I'm making progress on the game mechanics side. actually need to add some supply vehicles to the game now, then I can work on the launch queue and stuff... it's almost sorta like a game! echinopsis posted:is the game called space clock I'm still calling it Cosmosporia but I also thought of Extraordinary Orbitals, which sounds cool but I'm not sure it encompasses the scale of setting I want to get to eventually

ive started yet another game, basically Thrust with a better physics engine the physics engine is working and decent (although it doesn't handle friction yet) and its kinda fun to fly about but ridiculously difficult, I might have to add some sort of stabilisation https://www.youtube.com/watch?v=lb6V2G1CiQU

mate I love you rod rocket was inspired by something similar. I’ve spent a lot of time doing my best to make the whole thing quite controllable, as in tuned centre of gravity and played with different approaches toward turning the ship etc so its predictable and and you can fly it really well if you get good I wanted to recreate it in browser so people didn’t have to download a 300mb ue5 game just to see what I did

I think I added rotational damping so turning the ship didn’t leave it with too much rotational momentum because that made it hard to judge how far to turn to do whatever

what’s it coded in? yeah the balance is hard. and lol having a dangling weight is sure gonna make it harder? how’d you do the extra thrust? I had normal amount and then hold shift for extra if you can bothered, here’s a download link to download my game, idk might be interesting to see where I ended up with it https://mega.nz/file/bVJVFA4L#dFjHjDwVlVSu7uqhTZalPvYF7PxlXR7ueSgnsrGeYF4 yes its a 1 gb file. idk how to make it smaller hadnt played for a while. immediate thought was it is twitchy.. but I quickly got used to it, and there is less damping than I remembered. too much almost feels a bit wrong though. idk. I personally find it not too bad to fly around. I think a lot of others may not echinopsis fucked around with this message at 00:36 on Feb 28, 2024 |

that's kind of like the 3rd iteration of rod rocket lol, as in started from scratch 3 times and im still sort of working on crime committer https://forums.somethingawful.com/showthread.php?threadid=4048208 I made a thread for it so I could spam it without it annoying people root of all eval has offered to jump in and help for shits and giggles I seem to have a decent amount of "fun" building the framework for the game, having a new idea, working out how to make it work and seeing how it works.. but then I just kinda run out of steam, when the next step is actual content. idk what it is. cc could be broken down into 3 parts, the frontend - the actual game, the backend - trying to make it so people can basically have a profile and so they can come back later, and then the content itself. I also thought about making a thruster game in the browser https://rodtronics.github.io/rod_matters/ thats as far as I got lol BUT the proof of concept of getting physics running in the browser is right there. I kind of accepted that if I ever wanted anyone to ever play one of these games I'd defo need to make it run in the browser

in the most recent decker update i revisited grid widgets and made a lot of little improvements and generalizations like suppressing columns, permitting transparent backgrounds (so you can draw stuff behind them), a bunch of api improvements, and best of all a mode that lets you make selections cell-by-cell with appropriate keyboard navigation: the dream of making little crud apps continues to bloom

Caught a cold and couldn't lay in bed doing nothing, so I ended up recreating a piece of rare old hardware. I have an old Compaq Portable II. This is a luggable 286 machine  Yes there are two of them there. I've got more fun plans for the other one. Now there's only 640K of RAM on the motherboard, and no way to add more there. The usual way to add more memory to machines of this era is on an ISA card. But since there are only 2 free ISA slots, and only one of those is actually 16-bit, something else would be much more desirable. It turns out Compaq supposedly made a special memory expansion board for it, that plugs in underneath the motherboard and could add up to 1.5MB. But after pretty thorough searching I could find no photos or any reference to someone ever owning one. So these are at least extremely rare, maybe even just vaporware that Compaq never actually produced. According to the service manual, it would look something like this: Now, this only shows four chips that aren't simple 256x1 DRAMs. As long as none of those four are programmable logic of some kind, there is actually some possibility I could reason out the schematic for this, by looking at the circuitry for bank 0 and bank 1 on the motherboard, and what signals are on the connector itself. It quickly became obvious that U55 and U56 should be 74ALS245 transceivers to control access back and forth between the DRAMs and the ISA bus itself. U58 was probably a 74F32 which would be telling those transceivers when to turn on and off. U57 was a bit of a mystery. On the connector, I easily located all the address and data lines that would hook up to all these in a relatively obvious way, as well as the two CAS lines which are shared between all the memory banks. It took quite a bit more time poking around but I also found what had to be the three different RAS lines that would go to each of the three banks on the board. So already, I had a nearly complete circuit, maybe it would even work, as-is? But there was still the unknown chip U57 and half of U58 I couldn't account for, and at least three other signals on the connector that I didn't know the function of. Then someone posted to my thread on the VCF forums, they actually had one of these boards, and sent photos! Another collaborator stitched these together:   Over just a few whirlwind hours, we were able to pin down every last component and connection, and now there's a full schematic and faithful reproduction layout. I'm sure it won't be long before one of them builds a board and tests it out/shows it off on their YouTube channel. I've got more work to do since I want to make a version that uses 30-pin SIMMs instead of individual DRAMs, for my machine. quadpus fucked around with this message at 20:41 on Mar 24, 2024 |

hot drat, that is some nice reverse engineering. idk for sure, but how sensitive is it re: memory timings? i could see it having a hard time with random simms if it's expecting strict timings from the modules.

compaqs of that era are fuckers because they make everything proprietary i had a portable 386 with the orange gas plasma display. it used weird 42-pin SIMMs for RAM, and had four sockets. two provided the base 1MB, and you could fit another two to take you up to 2MB. but then beyond 2MB you had to fit an adaptor board that was really just an extension to add two expansion slots into an unused corner of the case, and then into that you could plug two 4MB RAM boards, except the 4MB boards were both different for no reason. so to max it out at 10MB you needed: 2x 42-pin SIMMs 1x expansion slot adaptor 1x 4MB RAM board (type 1) 1x 4MB RAM board (type 2) all this was proprietary, impossible to find even pictures of, and in the rare cases they turned up on ebay the seller thought they were worth $$$ and would rather not sell them than drop the price.

it’s supposed to use 150ns 256Kx1 DRAM chips, so if all else fails, simms that simply have those exact chips soldered on are not impossible to find
