On the other hand, this could be groundbreaking.
Only if you implement the ants' algorithm wrongly.
How likely is that?
Oh, wait, software....

How likely is that?There are going to be suboptimizations within the problem that only admit of heuristic approaches within given time, even assuming the whole damn thing doesn't somehow embody TSP.

@boomzilla Voltage is irrelevant. How much energy can it store? A 1pF capacitor and a 1GF capacitor can (or could, if a 1GF capacitor existed) both be charged to 1.5V, but there would be 21 orders of magnitude difference in the amount of energy stored in the two capacitors. Supercapacitors are used as a sort of battery, so energy storage matters immensely. Both capacitors could power a flashlight bulb, but one would do so for an extremely small fraction of a second, while the other might last for years.

@HardwareGeek
TFA said:These tubular biosupercapacitors are therefore 3,000 times smaller than those developed previously, but with a voltage roughly the same as an AAA battery (albeit with far lower actual current flow).
So at least the journalist isn't completely ignorant about the realities of electric current.

How about projecting a massive right in front of them. Simple but ingenious.
And I bet still it won't stop some people because they really aren't paying attention at all.

This tech, I have been tracking a few years now. This is what will get the fuck rid of tons of useless farm labor, and allow Florida to be turned into an automated greenhouse. This is the hand of TomatoBot - @Polygeekery, are you enough of a tomato pickin' man to shake that hand and compete?
And every bruiseless heirloom that goes in the bin says, there lies a mater pickin' man lawd LAWD

That's super cool.

@boomzilla Most of these are cool, some kind of underwhelming

@Gąska Just the video thumbnail makes me think this is really cool.

@Zecc means the thumbnail is working!
But seriously. It's even cooler than I initially thought.
Edit: should've put it in cool stuff thread. Oh well.

@Gąska What do you mean? It's here. :-J

Mark's opening on why version 4 is out:
Now you might be thinking: Isn't it a bit excessive to spend the last four years of your life trying to engineer the perfect revenge for porch pirates, just cause someone stole your package a few years ago and the police wouldn't do anything about it?"

And to that I say 'No'.

@Gąska Thank you very fucking much. I'm now helplessly seething with envy that my only quality is being shit at everything instead.

@Applied-Mediocrity don't fault your self-awareness, then, at least.

@hungrier Hmm, the Network puzzle is a bit difficult, and I'm glad I don't have to memorize the bit encodings for ALUs. (Also, may the plotting challenge die in a fire; it has both hidden conditions and bugs.)

You should have known, it was plotting against you.

Correction: it's a total pain in the ass as you've not got subroutines. Simulating branch-and-link yourself in that instruction set... not what I can stand today!

This man is relentless. His latest contraptions have released not just stink spray, he has moved up to smoke bombs, live mice, and creepy crawlers in several attempts to pay back scammers:

The computer ran in cycles of 45 minutes. It was used to calculate sums of consecutive integers to simulate a computational workload, which required 0.3 microwatts of power, and 15 minutes of standby, which required 0.24 microwatts.
x64 this ain't.
Howe says that the approach could be scaled up, but further research is needed to figure out how far. He explains that putting one on your roof will not provide sufficient power for your house. But in rural areas of low and middle-income countries, in applications where a small amount of energy might be beneficial, such as environmental sensors or charging a mobile phone.

So it seems like we will use algae as a living power source soon, just like machines used humans as batteries in the Matrix.

Probably the most adorable bagpipe ever, and the sound is fairly reasonable too:

It's a bit nerfed but it would probably retain significant combat effectiveness.
