Just found this subreddit, figured my entire collection would be a worthwhile contribution.

I feel like integrated GPUs will have higher graphics performance than an Atom as a... co-processor, I suppose.

Don't quote me on that.

In the first video, I like the woman in the background breaking down and cackling.

KarateFriendship · 2012-05-25T03:47:58.702336+00:00

Awesome. Thank you!

gimpwiz · 2012-05-25T02:41:13.852331+00:00

I'd guess 4-5 years.

My point 3 is pretty much precisely what you said.

The issue is that error-correcting codes are not perfect. If you flip enough bits fast enough, you will have errors. This is much more likely in space than on the surface of the earth, though 'much more' also means 'it will probably never happen'.

So yes, modern tech is pretty resistant.

I would love a review of Tres Generaciones, if the bottle is open.

Also happy reddit birthday!

Just out of curiosity -- what stops us from using robots to clean up such a hypothetical situation?

I understand radiation will interfere with radio signals... but in a closed environment, an emergency situation, you say fuck it to politeness and you take over a huge swath of bandwidth and blast the signal through at 1500W. I think in such a case, we'd be able to get a decent communication link to surpass pretty damn high interference and so on, and use the robots to scoop up your molten metal.

Though a passive approach is probably better, I wouldn't mind if such an active approach existed.

mepper · 2012-05-25T00:38:12.318206+00:00

There are actually problems with chips in space, unlike what flesjewater has said.

In short: there's a lot of radiation in space that can randomly flip bits here and there.

There are several things to note for this problem:

1) Rad-harding is a thing. That is, there are special fabs that print radiation-hardened chips. They somewhat reduce the extent to which radiation can cause disruptions.

2) Old lead shielding works very well. For a while, chip companies would find european houses with lead roofs (very very old houses), and offer to buy the owners a new, better roof + money in exchange for taking the old lead. The old lead has fewer impurities in it that are still decaying, essentially, than lead taken out of the ground. This was told to me by a guy who's been working on chip packaging for decades (and still is), but I don't have a source, sorry.

3) It was noticed very early on that bits would randomly flip on the chip. For this, we've developed self-correcting ways of storing data.

The end result is that, as baron_munchausen said, the mission-critical silicon is all super redundant and very good at withstanding open space. Laptops, on the other hand, might be more susceptible to errors from radiation but the spontaneous error correction on modern chips is very very good. Remember, random decay happens inside your laptop as well, and you're not constantly getting corrupted data.

Glass is fairly strong. I'd not be too worried about ~2kg of weight on the neck, considering the neck is a few mm thick and circular. It won't be collapsing in anytime soon and it'd take a lot more to shear it off, I think.

(Grain of salt: mechanical is not the kind of engineer I am.)

FratDoctor · 2012-05-25T00:23:32.434051+00:00

Carefully.

Hi everyone!

Here's a review of the standard Jack Daniels Old No 7.

Nose: Sweet caramel apple. Very very sweet, even for a bourbon(-esque) liquor.

Taste: Sharp alcohol. Bitter-salty-sour. Oak. Bit sweet.

Finish: A momentary sharp burn in the throat and a longer-lasting burn on the tongue. Just alcohol and oak.

Final Prognosis: This is a simple whiskey. It's rough. It has off notes. It would be decent for half the price. For what it costs, I'll skip it. If it cost half as much I'd give it 10 extra points for a passing grade, but:

Total Score: 65 / 100

That's a nice collection you have there, friend.

Shame if someone just... happened to come into your place and knock it over?

Listen, my boss, if you let him wet his beak a little, you know, pass a glass now and again, he'll make sure nothing like that ever happens.

Think it over. We'll be back.

(Can we request a review?)

RustyPipes · 2012-05-24T23:06:33.849622+00:00

Flair given.

And just making sure you weren't the one downvoting me :P

RustyPipes · 2012-05-24T20:37:45.072189+00:00

(You know I'm joking, I hope!)

How about if you char some cardboard, then wet it?

But seriously, thanks for the review, and you get to pick flair now.

RustyPipes · 2012-05-24T20:01:23.777645+00:00

Cave you ever considered eating wet cardboard? I hear it has very few calories, too.

djabrams · 2012-05-24T19:28:04.878991+00:00

I can't make out anything more than sipping tequila and tequila joven. Any help?

RustyPipes · 2012-05-24T19:27:05.281903+00:00

So... is old garage a good thing?

MrWriteNow · 2012-05-24T19:26:36.622390+00:00

I'd guess its production quality is low. You can fuck up a 100% agave spirit by using shit agave and treating it poorly, and it's even easier to fuck up the aging step if you use shit wood.

DrToonz · 2012-05-24T06:08:33.475339-07:00

This is true; a chip that can control a few actuators and provide diagnostic results can generally be done with modern tech for $4.

But on the other hand, a $4 chip today (ARM, ~600MHz, around 30-40nm) would seem very advanced in a time when the process node was 10x larger, and we can assume that chips from a couple decades in the future (sorry, rusty on terminator timeline) would be more advanced still. In fact, if they've broken the 10nm theoretical limit, that would be huge in the movie's timeline, allowing a jump that completely obliterates moore's law.

I'm gonna copyright the words foo and bar. TAKE THAT, EVIL PROGRAMMERS.

I'll also throw one out at this insanely complex piece of code I developed:

int i = 0;
while (++i <= target)
    dowork

See, it's my enterprise solution to the problem of for loops being ugly, with their stupid multiple expressions.

Enterprise of course means that it doesn't always work, it's bloated, and you have to pay me $50,000.

Worked for oracle, right?

foucaults_uvula · 1 day

But... why? Why? I don't understand how those would have the same word.

DrToonz · 1 day

Agreed.

Here's the way I think of it, from a design perspective:

I don't know my anatomy too well, but would it be acceptable to say that each individual joint in a terminator's hand would need to be controllable? That means some sort of movement device -- and if memory serves, the mechanical means to do so were similar to muscles in us.

http://www.youtube.com/watch?v=mStmiGS43jQ

Okay, so you have, let's say, 20 muscles in the arm that need to be moved. Estimate of course, because I don't know anatomy and I'm sure you can improve on the design.

Where do the signals come from?

Let's say you have 20 different actuators along different parts of the arm; some grouped together and some not.

Let's say each actuator needs a power supply (power and ground -- let's not ground to chassis since we want the terminator to survive some electrical disruption). So that's two wires. Then we have a signal wire. Then if we want a more robust design, we have a signal wire back to tell the status of the actuator.

So that'd be four separate wires per actuator. The ones in groups (like 4 actuators for 4 fingers) can share power wires, but that'd still be 2 + 8 = 10 wires. That's not even taking into consideration common design patterns such as twisted pairs (two wires) for one individual signal.

Do you want somewhere between 2 and 4 wires per actuator and more than a hundred actuators reaching back to the brain? That's a shitload of wires. Among other things, you would physically not have space to make the wires big enough to be fairly robust and insulated enough to not have significant crosstalk. This makes the assumption that the terminator doesn't use futuristic wires which are much better than what we have, but bear with me please.

So you have hundreds of wires running to the brain. That seems like an issue.

What if instead, for the group of actuators controlling each finger, you have a common chip? The brain tells the chip "move fingers like so" and the chip tells each individual actuator to move its respective finger like so. In this way, you can send four wires (power, ground, signal in and signal out) to control five fingers.

Or, more generalized, you could have one control point for the entire arm from the shoulder down, which then talks to several other chips down the line. Then you can control the entire arm with only a few wires to the brain, and the wires split off later down the line.

And of course this would let you build diagnostics into chips further downstream, so the brain doesn't have to waste time figuring out precisely what's the general status -- it was already told by the relevant controlling chip.

Do you agree that this is a reasonable way to design such a beast?
