The largest number is about 45,000,000,000 although mathematicians suspect that there may be even larger numbers. 45,000,000,001?

I mean you can only represent 0 or 1 with a single bit; having polarity on all your bits is kinda worthless for working with negatives, and you'd have to store the number as.... Are you sure? The whole point of ternary would be so that you could store more numbers in the same number of bits, no? I mean "takes care of negatives better" just makes no sense to me here. Wikipedia mentions that Russian ternary computers had the advantages of "lower electricity consumption and lower production cost." which makes sense; it says nothing about negative values. Young Freud posted:Also, I believe most modern computing exists largely thru "fuzzy logic" control and processing, where there is no longer just a 0 = FALSE and a 1 = TRUE, but and series of variables that exist between 0 and 1. What? Fuzzy logic is still implemented in hardware that uses hard binary. That's software, vs boolean software you do fuzzy logic software. But the hardware is always binary. Now maybe your hardware's actual transmission of the binary states has variable voltages and registers ranges, but that's not the same thing as fuzzy logic. I don't think you goons really know what you're talking about  Bits are always 0 = FALSE or 1 = TRUE, and all the hardware that manipulates them treats them as such. But you process groups of bits that represent different forms of data like floats, which can be continuous. Zaphod42 has a new favorite as of 22:28 on Mar 2, 2015 |

You guys are forgetting that bits can degrade & become corrupted on the path from their home IC to wherever they're going. It was the development of new capacitors that even ALLOWED the transmission of HD-ready data through the circuit leads. Before graphums was developed people used to have to use wax paper capacitors and it was a nightmare trying to get enough data from the wall hose, through your Musicatrix, and out the loudening tubes on the other end. And, if any of your neighbors happened to be using their Musicatrix at the same time, their bleedthrough affected the quality of the data coming out of your wall hose, as well. I remember as kids we'd get every grinning knave on the block to pump out some really cruddy gnarltunes very night at 6 to make it impossible for our parents to listen to the news. Anyway, just wanted to say thanks for the Popular Mechanics style runthrough of the new technologies you all have developed. Is there a bluetooth typewriter for my mobile hellobox? I can't figure out swype.

I guess balanced ternary might make it faster to calculate pi using the Leibniz formula, if he was in the 60s and building a computer from the ground up. He is going to do none of these things though.

Guavanaut posted:If you use balanced ternary throughout (including storage), it saves on the number of bits that are needed to store any given value. Normally you'd have to use 2s complement, signed bit, or some other method of storing the number, which means that storage bits get used up representing the sign of the number, e.g. you can store -10 as 0-0- with no flag. There are some other calculations that are simplified through balanced ternary, like fractions, but I forget exactly how. It comes at the disadvantage of needing positive and negative power rails and more complex controller circuitry. Hm, balanced ternary does let you store negatives slightly smaller then and reduces the number of carries in multiplication which is cool, but you could use the same hardware with a standard ternary in order to store much bigger numbers in fewer bits (If I'm thinking about this right), so I'm not sure it would be worth it. Still, its a loving weird/interesting idea.  I'll have to read about this more...But yeah since modern hardware is all binary using slow ternary computers wouldn't help you vs. the latest binary hardware. bvoid posted:shut the gently caress up you nerds Fair enough.

Still, its a loving weird/interesting idea. :russia: I'll have to read about this more... You have to remember, this was a thing being implemented when having mere thousands of bits of storage was considered huge, often with key parts of the system only being able to handle a few hundred bits in near-real-time (as opposed to having to wait for drum memory or other much slower kinds of RAM). Being able to save a few bits there could mean having substantially more effective storage and save thousands of bucks. It's something that simply stopped being all that helpful by our time, when you have people not finding it worth it to pick up a free gigabyte flash drive or 2 GB memory expansion.

I said from the very beginning that using ternary to save bits with storage makes sense. That's obvious. But that's how standard Ternary systems work, and those don't get you magic negative number advantages. Whats not so obvious is why you'd waste those extra bits to get a sign value for each bit. (Balanced Ternary) But it seems there's some cool reasoning. You're discussing Ternary v Binary which I totally understand already. What I didn't understand was balanced ternary and why you'd use it. But I'm starting to get it. (Overall though probably not better which is why we don't use it)

Balanced ternary was easier to implement and design for, when you're working basically from scratch. Much of the equipment used at the time, it wasn't much effort to modify it for that, while doing non-balanced required more effort.

Single layer DVD-Rs are about 20 cents. To match the current pi record would take about 1500 DVD-Rs assuming packed BCD. Not bad. He's covered his blank DVD cost. edit: Although since his goal is finding the last digit of pi, he's covered 0% of his blank DVD cost.

This is refreshing after all the "sneak away like a thief in the night" we expect from failures of funded projects. I also liked how he explicitly spelled out the lessons learned and it sounds like they did a proper post-mortem on the project. They learned some hard, hard lessons on budgeting and project management and that weird poo poo happens that's out of your control. Between this up-front "we hosed up" and if they actually follow through with the refunds, I think they will have salvaged enough of their reputation to maybe revisit this in future (do I want a cheap, high speed wireless trigger? Hells-yeah I do).

Now I'm thinking of the business model: 1: Make a flexible funding campaign. Set the price high enough to never actually be reached. 2: Fill it on bullshit argument-inducing points 3: Profit off all the people who pay a dollar to tell you that you're wrong. Too bad he's on a fixed funding model.

I flicked through kickstarter last night to check up on some games I pledged for which are delayed, but I found other poo poo too! Lose weight through not the ab burner I'm no biochemist, but deliberately inducing hypothermia can't ever be a good thing, can it? Either this will be an insignificant amount countered by physiological mechanisms, or it will induce actual hypothermia, and be associated with all the bad stuff that goes with that. What I especially like is they've included a section on how this is totally not pseudoscience, you guys. Apparently extrapolating mouse models looking at specific gene/protein activation into general weight loss in humans is legit.  Ring, maybe not that bad, but just utterly uninspired. A carbon tube cutoff that looks lovely. They claim that quote:The Razer Ring is totally unique and intriguing. It is a great conversation starter. I have no idea what sort of conversations they expect this ring to start, other than very short ones that begin with "hey check out my awesome carbon fiber ring" Uninspired wallet #443241. What I like about this is that it manages to be the same size as a regular wallet with less carrying space. If all you need in your day to day is four cards and a single bank note, just use a pocket.

You can eat cookies and cakes all you want, just eat only while submerged in a freezing ice water bath! Your body will burn twice the calories to keep you alive! It really works! It's basically what the pitch is, but a portable version. And just as stupid Kudos on the guy for weight loss, but he straight up says it's from a good specialty diet and a lot of exercise, not some magic vest. With or without a stupid ice-pack-stitched-in-a-vest, if you put in that much work you will get results.
