Clickbait, thought it was about a garbage collector open source library!

We thought of sending puzzles to the worker that would have to really be computed by the VM and would take some amount of time until it was possible to be faked, or would have changed by the time a human could decipher the puzzle and return the expected result, but so far we're only ignoring bad actors and sometimes comparing results from different actors until a quorum is found among results

Well we noticed that flash ads sometimes take up even more than 100% of a CPU (meaning it can spawn threads and use multicore processing), video ads perhaps even more since they may get to be gpu accelerated, as CSS3 animations. We figured if people are spending this much CPU cycles for advertising, than why not clean up all the advertising and use the CPU cycles for some protein folding and finding a cure for cancer to make a website owners, visitors and a group of researchers happy ?

We -really- don't want to seem sketchy and immoral. We plan to stop computing after a certain amount of time (still to figure out, so far we don't have that many tasks running for it to be significant), and we completely block mobile phones and tablets while the Battery Status API isn't present in all devices (http://www.w3.org/TR/battery-status/ only Firefox implements it currently)

that may be harder to do efficiently than building the entire platform and we're an extremely small team. I'm sure some day we'll do it but can't prioritize that now.
joaojeronimo | 12 years ago | on: Ask HN: What would you compute on 2000 badly behaved worker nodes?
Sure! You'll want to block ss.crowdprocess.com
An opt-out is under way, one website requested an opt-in but we haven't translated that yet: http://cdn.crowdprocess.com/opt-in.html
joaojeronimo | 12 years ago | on: Ask HN: What would you compute on 2000 badly behaved worker nodes?
That's actually pretty good advice, except it may be hard to find legal and moral things to run. We wanted to find the cure for cancer and not produce rainbow tables or do DDoS attacks.
joaojeronimo | 12 years ago | on: Ask HN: What would you compute on 2000 badly behaved worker nodes?
There is an opt-in: http://cdn.crowdprocess.com/opt-in.html (only one website requested it so it's not in English so far).
It's as immoral as advertising, maybe even less. In advertising you show up at a web page and see tons of things that you did not want to see or did not bring you to that web page, sometimes shift your focus and annoys you. It's the same with CrowdProcess, except instead of annoying you, we annoy one CPU core. We believe that while being more expensive than traditional datacenter grid computing, it may be less expensive because it only has to outperform ads. We don't compute on all the CPU cores, of course, only on one.
We actually ask websites to tell they're a part of this, but we cannot control what they do because they can simply display:none.
joaojeronimo | 12 years ago | on: Ask HN: What would you compute on 2000 badly behaved worker nodes?
It's not possible, sorry. It's possible if you ask us to access a certain address, but to the outside world it's not allowed. It would be pretty cool to have distributed web crawlers but it would also be extremely dangerous if someone decided to use CrowdProcess to do a DDoS.

that's a pretty good one, especially since mining Litecoins is still profitable on EC2 (at least last time I checked). I was planing to write something like that on the weekend but couldn't, will have to do it pretty soon...
joaojeronimo | 12 years ago | on: Why mine Bitcoins when you can use Computing Power for Hedging?
not what we're trying to do
joaojeronimo | 12 years ago | on: Why mine Bitcoins when you can use Computing Power for Hedging?
Yup, still tons (really tons) of people ask us why we mine bitcoins.
joaojeronimo | 12 years ago | on: Why mine Bitcoins when you can use Computing Power for Hedging?
The title has everything to do with it, it's about a better alternative to mine bitcoins
