Comment: Self -Driving Neural Network Toy Car (Score 1) 22

This guy built a self-driving car powered by an android phone and a laptop. He did something similar with a raspberry pi in place of the phone. I find this fascinating. In essence, he taught the car to drive by driving it around a black track delineated by white boundaries, with the computer recording a basic video of his driving technique. The neural network was then trained to drive like a human. The neural network ideas were contained in this free Stanford Machine Learning Course by Andrew Ng. It would be unbelievably cool to me if someone could make this technology more accessible to a wider audience.

"...as they create a contact bridge between two points when they get electrocuted they release an alarm pheromone," says UT research assistant Edward LeBrun. "The other ants are attracted to the chemicals that other ants give off," he adds.

What kind of survival mechanism is that? "Oh! There's danger over there. Let's all go check it out..."

Given that(among the ants that don't have even cooler mechanisms, like specialized suicide soldiers who blow themselves up to shower the enemy with toxins) "swarm the enemy and keep biting and stinging without regards for casualties until nothing that isn't us is still moving" is considered a valid strategy, the chemical signalling actually makes sense: If an ant from another colony, or a predatory insect/arachnid, attacks a single ant, the ant's body automatically releases the alarm pheremone and the attacker gets zerg rushed.

It's just that, against implacable electronics that are totally indifferent to anything except being insulated by the uncounted bodies of the slain, this tactic doesn't work very well(see also: mammals that 'freeze' to avoid predators; but discover that cars aren't visual hunters; but they do kill anything that gets in their way)...

Seems like having a predilection for something that kills you is not an instinct that should be selected for. If they are electrocuted by the electronics shouldn't this problem take care of itself sooner or later?

I suspect that it depends on whether sensitivity to electrical fields is useful in other contexts, or(if not directly useful) at least tightly-coupled to some other sensory mechanism that is survival-critical and will take quite some time to iterate toward an electrically insensitive replacement.

Mass death upon the power lines is obvious folly; but electrification is, what, a century old(in any ecologically-relevant amount, I know about various independent developers of primitive chemical batteries going back a great deal further; but that sort of scale barely matters), the blink of an eye in evolutionary time.

If this electrical sense isn't all that useful elsewhere, or is just some accident that didn't previously cause trouble, it could actually be culled from much of the population fairly quickly. If it has some other use, or is connected to genes that code for multiple things, some of them extremely useful, they might take ages, if ever, to stop doing this.

I know most of /. will scoff at this assertion, but we may be witnessing a Biblical prophecy come true: "And there shall be destruction and darkness come upon creation, and the beasts shall reign over the earth."

By mass, beasts have always reigned over the earth... A mixture of applied landscaping, chemical warfare, and rifles have allowed humans to carve out an enclave free of large mammals we don't approve of, and some of the nastier bugs and microbes(wealthy areas of the Northern Hemisphere, at least. Your mileage may vary. Offer void where restricted by law or subverted by rapid evolution of antibiotic resistant microbes. Terms and conditions may apply); but we've never been close to having the upper hand against things too small to shoot and too resilient to just habitat-destroy into submission.

These foreigners are destroying good ol american jobs. I am liberal except for when it comes to things that effect me as I am a hypocrite.

Ah yes, isn't it repulsive how those 'liberals' just can't stay consistent on their support for indentured servants when their own economic interests are on the line? Truly a refutation of their ideology or something...

I have to wonder why they talked to the VCs at all... I can imagine taking the risk if you've just started somebullshitwithnorevenuemodel.com and crazy guys in suits are offering you a giant stack of pretend internet money for it; but why would a company with an actual shipping product, and sales, and such, risk going up against the elite equity-diluting and value extraction skills of a hardened VC?

I've long noticed that ants seem to have a predilection for electricity. They crawl all over electrical conduits, enter homes at electrical outlets, etc.

It's because they can sense electromagnetic fields, which all electronics give off. Of course, the solution for dealing with these new ants is simple, but counterintuitive -- spray everything with this 'alarm' pheremone. If ants navigate by scent trail, and that's how they rebuild their nests, and it's too challenging to remove the scent trails... then you are left with only one option:

Blind the little bastards by coating everything in it. It's my understanding that, without those trails, they'll be helpless to organize to find food, each other, or even the way home. Everything depends on those trails... so if you overload their sense organs and blind them, they'll perish. After they're dead, the pheremones sprayed will slowly dissipate, but importantly... the trails they've laid down will dissipate faster, so the area is then chemically neutral again.

It is, quite literally, chemical warfare. (-_-)

The second experiment added some Linux laptops that ping-flooded to generate lots of network activity. The second experiment showed a clear increase in plant "damage" /lack of development.

Were the laptops located so that their fans wouldn't be blowing hot air past the seeds, heating them and sucking the moisture out of them?
