Holy Batman! Now apply Moore's law to that and figure out where we'd be in 10-20 years #SCARY_AF
- arthurcolle 6y agoMoore's Law doesn't really work anymore. It hasn't held for the last 4 years, IIRC. That's why a lot of focus has been on multicore systems to try and get new speedups based on parallel computing as opposed to getting purely single-chip improvements.
- mpfundstein 6y agoit indeed doesn't work anymore for single CPUs but still seems to hold for other thibgs. eg memory (ddr5) or chipsize (see 7nm chips)
- ComputerGuru 6y agoMoores law is strictly about transistor count and not performance, it is just that we are only now seeing the two come decoupled.
- arthurcolle 6y agoAren't transistor count and performance very positively correlated?
- ComputerGuru 6y agoThey are, but performance in teraflops is not the same as performance in general computing activities. We are now scaling horizontally within a single cpu package.
- arthurcolle 6y agoWow that's crazy, I had no idea. Do you have a link on arxiv or something I can check out?
- beamatronic 6y agoAlso figure the US Government probably had this 5 years ago
- op03 6y agoI'd like a spider cam. I find it a great mystery how spiders survive in rooms which seem absolutely empty/abandoned etc.
- lanius 6y agoDitto for cockroaches. I'm curious where those little buggers disappear to when they manage to escape from me.
- throwanem 6y agoOften they can survive quite a while without food or water, as long as the temperature and humidity are within some fairly generous extremes, although very dry air poses the risk of dehydration since their respiratory systems and body volume offer little ability to retain a reserve. But they rarely have to go that long without a meal, because if a spider can get in, so can suitably sized prey - and will. Next time you find yourself wondering how a spider thrives in an empty room, take a close look at and under her web. Most likely you'll find cocooned prey in both places - fresher prey items in the web, spent ones underneath it. Spinning a web is a metabolically very expensive process, requiring as it does a great deal of protein - protein which can only be recovered by either eating the spun silk again, or eating prey trapped by it. Spiders consequently have to be pretty smart about where and how they do it, because the ones who aren't tend not to reproduce. So it's usually a very safe bet that, wherever you see a spider web, it's there because that's where the prey tends to be. It can be interesting to see what sort of prey that is - for example, right now in the basement of my ~130-year-old house there are a couple of very happy cellar spiders enjoying a steady diet of pill bugs, and another by the kitchen radiator who all on her own solved most of an ant problem for me before I ever realized I had it. They're actually very desirable animals to have around, in my thoroughly considered opinion, despite getting about as bad a name as wasps - and with just as little reason.
- op03 6y agowow had no idea they eat the silk. They are so small that I only notice them because of the webs and long strands flying around. I'll keep an eye out for their prey :) Thanks for that interesting info filled comment!
