You know, a chainsaw could either be turned on or off, much like a bit, 1 or 0. So if you become a machine that would both catch chainsaws and launch them into orbit at a steady rate, as well as determine if each chainsaw is on or off, and has the capability to turn the chainsaws on or off itself, then you could in theory build an orbital chainsaw drive capable of storing and retrieving data, right?

Using a fractal tesselation where a square is split into four squares which is split into four, ..., you can chose one of a billion squares with 15 up-down-right-left choices and see where you are going :-) I ever only convinced my brother that it was a good idea because storing that amount of 3D models and serving them to users was insane scientific fiction back then (1996).

[@trainzack]

I think the capacity of the tera-wield is overestimated. 11km/s escape velocity aside, the density of the chainsaws at the point where you grab them is not the limiting factor, but rather the density of chainsaws at the furthest point. According to Kepler's second law, the velocity of an object in an elliptical orbit decreases as distance from the focus of the orbit increases. Therefore, the density of objects in an elliptical orbit increases as you get further from the parent body, so if the chainsaws are packed maximally at the closest point, they would have to be packed supermaximally at the furthest point, which would cause all sorts of problems.

[@notnullnotvoid]

I wonder if you can juggle multiple (multiplexed) streams of chainsaws with slightly different orbits to get around this problem. That way you get close to maximum density at periapsis (the only point where the streams converge) without exceeding maximum density at apoapsis (which is actually several different points for several different streams). But I imagine it would be hard to schedule since the orbital period of each stream will be slightly different, so they will go out of phase with each other.

[@petros_adamopoulos]

@@notnullnotvoid Hmm a teraplex-wield... You wouldn't speak of orbits anymore, but of a swarm.

[@trainzack]

We do have to consider that where we stand on the surface of the planet also matters due to the unfortunate fact that the Earth rotates. The easiest place to stand for the original idea would be on one of the poles, so that you can simply dp a 24hr rotation to cancel the effects, but a crafty chainsaw juggler maybe could stand somewhere else and throw them at a speed such that they sync up to the day cycle. And then there's the tilt of the Earth, which when combined with Earth's rotation around the sun, means that the plane of our orbits will also change.

[@IpolsYoutube]

@@notnullnotvoid throw at different Speeds to solve schedule problems

[@BrightBlueJim]

Both the Internet ping and the chainsaw juggling are just delay line memories, which was one of the most popular forms of storage in early computing. Actual implementations included pressure waves through mercury tubes or quartz crystal polygons, torsion waves through magnetostrictive wires, electrical pulses through coaxial cables, transmission lines or chains of inductors and capacitors, and later, semiconductor shift registers. There is really no limit to what you can do with delays, since these involve storage in some kind of medium (which can be very close to free, in cost per bit, chainsaws notwithstanding), where the longer the path through the medium, the higher the capacity but also the longer the latency, but you can mitigate the latency (as was done in practical applications) by adding parallel channels. As you mention, slower media is more useful, since it holds more data per unit time, which was why most of the historical implementations used acoustic waves. Harder drives I've seen either proposed or actually tried, include moon-bounce lasers, spots of light on glow-in-the-dark tape, ultrasonic chirps through air, and magnetic tape loops.

[@soylentgreenb]

Another early form of memory was Williams tubes, which used charge buildup on a CRT screen for storage. As completely retarded as that sounds, they were at least actually random access, which makes them one step up from these delay-line memories.

@@DanJanucik Ah, my esteemed interlocutor, perchance might we pause to reflect upon the diverse symphony of voices that forms the vibrant tapestry of our shared digital discourse? Each individual, with their unique perspective and expressive modus operandi, contributes to the rich and multilayered narrative that unfolds in the comments beneath the creative beacon of the video in question. Your observation, although succinctly articulated, seems to bear the weight of a somewhat judgmental undertone. It is indeed true that brevity can be the soul of wit, as our bard of Stratford-upon-Avon once opined. Yet, should we not also make room for the ebullient expansiveness of those who choose to delve into the depths of analytical discourse, to dissect and ponder the myriad nuances that others might overlook? In the grand theatre of human interaction, there is a part to play for both the concise critic and the verbose analyst. To dismiss the latter as the product of a "tortured neurodivergent mind" is to stifle the richness of our collective conversation. The beauty of discourse lies in its diversity, and in that spirit, I entreat you to adopt a more charitable stance towards those whose expression takes a different form than your own. So, my friend, while your viewpoint is appreciated, let us remember to approach each other with respect and understanding, cultivating an environment where all voices, whether succinct or expansive, can resonate in harmonious symphony. In this manner, we might avoid falling into the unsavory role of the discourteous critic, and instead uphold the principles of empathy and tolerance in our shared journey through the realm of digital discourse.

I actually created my own Harder Drive in Minecraft using Shulker boxes and a clock controlled chain of hoppers. Items are pulled from the box in sequence, all non-stackable to ensure the correct order. Each hopper feeds an item into a brewing stand, then deactivates, ensuring one bit per stand. If the item in question is a potion, it will enter the brewing stand, triggering a comparator and registering a one. If it is a sword, it enters an overflow hopper instead, leaving the comparator off. Reading amounts to waiting for each item to travel through the system and power a series of indicator lamps. Writing requires all bit detector mechanisms to be emptied before a new pattern of items is piped in, which I can't yet do automatically. My sporadic interest in this project, plus my habit of not backing up my Minecraft worlds, means I've probably never built it the same way twice. Maximum capacity amounts to an incredible three bytes, with two or three slots left over. This could be doubled if I used a large chest instead of a Shulker box, but I wanted to emulate a "removable drive."

But the problem was that dialup was slow and unreliable and they'd have to make big servers that hold all the games and it would be too big and clunky. Their solution was to send low cost servers to cable companies around the country and every month they'd ship a hard drive containing that month's games. This server literally just broadcast the games over and over in a loop. The "modem" was not a modem at all, it only demodulated. You'd start up the modem (plugged into the cartridge slot, the Genesis just thought it was a game) and it would wait for the menu program to come around on the loop. It loads the menu program, you pick a game, and then it waits for the game you picked to come around. You get on demand content without ever having to communicate back to the service.

The Tetris Harder Drive(R) with all the boards arranged on one screen makes me think that it would be a funny idea to try to use that arrangement as a screen, with each board representing a pixel, using dithering for grayscale coloring, and then again play Tetris on that board. Kinda like implementing GOL in GOL.

I like it! As you can see from the part at 22:40, there's a bit too much distracting other junk (the parity/support columns and the rest of the interface) but I think it'd be a good demonstration if that stuff were cropped out.

[@danmerillat]

If you carry the 1 you should be able to use odd-numbers of 'bits' per line, no? It should change from a single write strategy to 3: the existing strategy for an even number of bits, the strategy for an odd followed by an even, and an odd followed by an odd. That would give you 2^10-2 potential patterns or roughly 4-options per byte, which could be used to optimize write speed by planning ahead.
