Someone could make a URL shortening service that frames sites, including the mining JS. Users could sign up and get a % from the mined coins on links that they share. As many people are pointing out that GPUs are faster for mining that CPUs, would you be able to make use of a GPU with WebGL (or GPU-accelerated Flash)? I guess the GPU computations don't fall in the spec of WebGL though.

I think a bitcoin browser plugin would be the sanest choice

It is bad to use a bunch of the user's CPU without any notice. They will probably notice that your site makes their computer slow and never come back again. Also, once they find out you've been using their CPU power/electricity/battery life surreptitiously for private, unshared gain, you will probably have some angry customers. Additionally, does this automatically hook in to slush's pool or something? Bitcoin mining…

all this new javascript stuff only gives me more and more reason to use noscript

Going meta: I've seen in the last few weeks apparently relevant and polite posts that had been flagged dead[1]. One of these was a post by jashkenas in a CoffeeScrit thread. This one could hardly have been more on topic. Is there a new moderation policy, or is it a bot with a happy trigger? [1] In this thread, http://news.ycombinator.com/item?id=2566826 , a post by jhuckestein, and http://news.ycombinator.com/item?id…

I'd be curious to know the answer to this too - I've seen an increase of "one off" seemingly acceptable posts being flagged dead, and browsing their post history it wasn't cases where they were set to auto-dead.

How is bitcoin like the gold standard? Bitcoin is backed by what? It's more like a purely speculative currency. It's artificially scarce and worth nothing apart from it's perceived value. At least with gold there are many industrial uses for it. You can't do anything with a bitcoin other than trade it.

It's artificially scarce and worth nothing apart from it's perceived value. Are there any official currencies that this doesn't apply to?

Ironically - your example speaks against itself. 100GB Drive is a very precise and agreed upon way of referring to a drive - it means 1x10^11 bytes. 93.1 GiB drive is unusual - we don't typically use powers of 2 when referring to drive length - so if you really mean 93.1 GiB, then it's important you call it out as such, or people (storage admins, driver manufacturers, and operating system developers) will understand…

I thought this was the common way (gibi that is) to refer to harddrives in the OS, I thought that that was the reason harddrives were 100gb when i bought them but only showed up as 93gb on my computer.

It is. Everyone except the hard drive manufacturers uses GiB for technical reasons. Hard drive manufacturers use GB for marketing (and clarity, but mostly marketing) reasons.

It used to be common to speak of sizes in "hard drive megabytes". Eventually, the disk manufacturers won the pointless semantic battle and that went away.

In practice, it matters not in the slightest.

Neat! Distributed computing with JS is an awesome tech trick, some friends and I did something similar back during Node Knockout (MapRejuice: https://github.com/ryanmcgrath/maprejuice ). Curious to see what you guys think of the ethical side of it though - do you let this run on mobile, etc? This will almost definitely cause extra battery drain on mobile devices, you think it's fine to have this happen without user c…

BitCoin mining could replace banner ads. I have Flash on my mobile, which often uses lots of CPU usage for ads. You could argue this is the same.

Yeah, you could argue this... and then we could just point out that Jobs & co are right, and Flash has been a battery hog since the dawn of time. This is a reason why the iPhone can be so performant; you're arguing that it's perfectly acceptable to degrade the otherwise shockingly good performance of a mobile device when it can be avoided entirely.

Flash needs to stay out of this argument, as at the end of the day it's still a real ethical question - how much CPU are you realistically allowed to take and continually use from a user visiting your page?

If you could turn out a bitcoin per day per player, that's massively more than the subscriptions at today's rates. Of course, there's no guarantee that you could do this, and there's no guarantee that today's exchange rates have anything more than blind optimism keeping them afloat, but the idea's not inherently stupid. In fact, it might be an interesting way for EVE (for instance) to link ISK to real-world value. Th…

"If you could turn out a bitcoin per day per player" Can't be done. According to this BitCoin calculator[1] you need to generate 245 Mhashes/sec (mega-hashes per second) to generate 1 bitcoin per day today. (Remeber that number will go up as time goes on) I assume that calculator is for 24/7 calculation (which you won't get with gamers), let's assume they are hardcore and play 6 hours per day, every day. You can't de…

Nice number crunching..

But then let's reassess this 1 BT/Day thing. That's $8 a day right now, you'd be pretty pissed paying $8/day for most any game.

What if we said 1 BT/month instead? Then all your numbers kind of point to that being pretty feasible no? If I'm reading your calculations right, then a gamer with one GPU would generate 2 BTs per month.
