  1. Re:sibling fairness on New Website Offers Provably Fair Solutions To Everyday Problems · · Score: 2

    Except you assume that all the players are actually honest about every option and valuation and not just playing the algorithm. Imagine a well off and not so well off student decide to share an apartment which consists of two rooms, one small and one big and a common area. They can't agree how much the extra space is worth, now the poor student he doesn't want the big room. He just wants the other guy to pay this "fair" share extra so he can pay as little as possible. Now the rich student he knows the poor student is trying to cost optimize, he doesn't want to pay extra for extra space. So he doesn't have to bid a "fair" value, he just has to outbid the poor student.

    If the poor student tries to push up the price of the big room or the rich student tries to penny pinch low-balling the price and they end up swapping rooms neither is going to be happy, the poor student didn't really want to pay extra and the rich student didn't really want the cramped room. They were just trying to use their own knowledge of the other person's preferences to maximize their own value. No algorithm can reasonably cope with that because the total utility is not fixed, it's not like a cake where the sum always adds up to 100%.

    You can see this for example in divorce proceeding where something has different sentimental values. You want that family heirloom? Well I don't really want it, I'm just trying to gouge you for as much as I can. If you gouge too much the other person may give it up and say "fuck you too". The threshold is an essential secret which limits the gouging, if you knew that $100 item has a $1000 sentimental value you might bid $999 even though you don't want it for $101, you want to lose but in the most rewarding way.

    It doesn't even have to be the big stuff it might be chocolates in a bowl, if you know your buddy is big on toffee you might grab one even though you don't like it much because you know your buddy will offer a good swap. Until he catches on and lets you simmer with your toffee because he knows that's a lose-lose situation you want to get out of too. It's like trying to stand still at a game of rock-paper-scissors, in theory they all have a 1/3 chance of winning but if you pick rock every time you'll soon lose every time. The way to win is to recognize your opponents patterns and exploit them for a better than 1/3rd chance.

    just another liberal pipe dream that will never actually work

    A liberal pipe dream that will never actually work as long as oil is cheap, perhaps. But it's made me a whole lot less concerned about peak oil, here in Norway around 9% of cars sold this year are electric through subsidies. Another 9% are hybrids. If oil prices doubled or tripled I'd expect those numbers to go way up. Before it seemed like peak oil would be the end of personal transportation as we know it, but even if electrics never get quite as cheap or convenient as gas and diesel they'll do. Good enough for my commute, shopping and local activities, visiting nearby friends and family and at least in Tesla's case cabin trips - not the most remote cabin in the world, but still. Of course it now depends on cheap electricity, but at least there we've got many different sources and they don't have to be compact, light and portable like an internal combustion engine.

    Particularly if it eventually gets paired with autonomous cars, cargo generally isn't in any hurry and the lorry isn't paid by the hour. Tesla did US coast-to-coast in 76 hours, the record ignoring all laws and sanity is 29 hours so it's not like they're orders of magnitude slower even if the truck has to stop for a recharge every hour or two. It's only very inconvenient as long as you need truck drivers. Basically it looks to me like we have a workable solution for when oil runs out, if we'll switch faster due to the environment that's nice but I'm guessing push will eventually come to shove anyway even though "unconventional" oil and gas extraction has pushed it back another decade or two.

At any rate it's unlikely it would help here, the courts would probably never manage to pursue it while they already got what they wanted.

    The purpose of providing this counter-notice is that you now have a dispute (claimant and counter-claimant) that the courts would like to see settled outside of court. That part should have been optional and shouldn't need to involve revealing your identity though. I think it's reasonable that your personal information is part of your counter notice and kept in escrow at the service provider to avoid "Mickey Mouse" filing counter notices, but you should get one of three choices when it comes to passing it on:

    a) Use your contact information as legal contact address, like today. Basically, you represent yourself.

    Yields are a matter of process tuning, if one CPU works well it means the others will too eventually. And the new Core Ms are down to 82mm^2 from 131mm^2, meaning more dies per chip which translates directly to higher margins for Intel. It would mean lower prices, but there's no competition. And eventually they will have tuned it while AMD haven't, it's only a win if AMD never ever has to do the same job.

    What jobs do Joe and Jane Average have that won't be well served by a C2Q or Phenom X4 from 7 years ago? None, not a damned thing, in fact many can get by just fine on a C2D or Athlon X2 and never notice any difference because they just aren't stressing the chips.

    Yes. Which leaves the question, why should they buy a new machine from AMD rather than some second hand machine that used to be state of the art 5 years ago? While the people who do want to push the envelope in performance/features/battery life/whatever buy new Intel machines instead.
