Comment Re:Solar panels are cheaper but the rest isn't (Score 1) 735

TV/cable box/modem/router comes out to around 300 W (assuming flat-screen).

During a power outage, would there still be a signal for your cable box or modem to receive? I don't know where the last distribution step gets its power from, but if it's from the same grid as your house, it will be down too during an outage.

Comment Re:Match Your Power supply to System Power Reqs (Score 3, Informative) 328

If you look at efficiency graphs, you'll see that power supplies are typically the most efficient under moderate load: at low and high load the efficiency drops. A typical desktop or home server is idle most of the time, so idle efficiency will have a big impact on the total efficiency. If you over-dimension your power supply, your idle load might be 10% or less of the max rating, which is far from the optimum of the efficiency curve.

I'd recommend getting a power supply that can deliver a bit more than what you need, for example 450 W if you think you need 350 W max. A bit of margin is useful since you might not have found the actual worst case or you might want to add components later. Also it avoids poor efficiency at the high side of the curve when the system is under load.

No, this is an actual low-power CPU, not a desktop part. Wikipedia does mention rebadged Athlon XPs being sold as "Geode NX 2001", but there were real Geode NXs as well.

Comment Re:We are the 30% (Score 1) 724

a) Pretty much every other app store out there has the same deal

The other apps stores saw Apple taking 30% and still getting plenty of developers, so why would they pick a lower percentage?

In my opinion, the problem is not that Apple takes 30%, but that Apple's store is the only one you can use for iOS devices unless you decide to exploit your own device (aka jailbreaking). If third-party app stores were supported, there could be competition between them and there would be an incentive for them to operate on thinner margins. However, with Android this is possible and I haven't heard yet of flourishing 3rd party app stores there.

Comment Re:Pointless anyway (Score 1) 143

Fusion is easy at the stellar scale, since gravity takes care of both ignition and containment. On a smaller scale, we'll have to build and maintain machines for that which costs money. How much is hard to predict when we're still in the prototype stage, but there is no guarantee that fusion power will be cheaper than existing forms of power generation.

Comment Re:"Free" market fail (Score 1) 205

The challenge is that other carriers can swoop in and pretend to be regular customers, sending precisely the most expensive calls to a provider but using other routes for the rest of the traffic -- "cherry picking". Carriers will typically deactivate the accounts when they discover the cherry picking, but that is a whack-a-mole game.

From the article it seems that is already happening: those low-cost carriers that do not drop the call often forward it to another carrier, who makes the same tradeoff and forwards it again and in the end no-one connects to the recipient.

The only real solutions I can see is to either have uniform termination costs or have different quoted prices for routing a call depending on where that specific call is going. It seems the FCC is choosing the former, but that's a long-term solution. I'm guessing the latter would require significant changes to the systems directing and billing calls so that wouldn't be a short-term solution either.

You can't just telll the LD carriers "you must complete this call" if doing so costs them more than they charge.

The long distance carriers should take "you must complete this call" into account when setting their price.

Likewise, the small rural phone companies must receive enough revenue to maintain their operation.

Currently high fixed costs of maintaining the infrastructure are covered by higher per-call costs instead of higher monthly fees. Of course higher monthly fees won't be popular with people living in rural areas, but it would more accurately reflect the actual costs.

The only way this is going to get fixed is if sane regulation is brought to bear.

According to the article, there is regulation on paper but it is not enforced.

The domain was registered less than a week ago and some of the registration data doesn't look valid. Also nasa.gov says "The next news conference about the NASA Mars rover Curiosity will be held at 9 a.m. Monday, Dec. 3, [...] Rumors and speculation that there are major new findings from the mission at this early stage are incorrect." So it's probably a fake.

Comment Subway Shuffle (Score 1) 165

My nephews want to play Subway Shuffle every time I bring my iPod Touch. It's a train shuffle game, but with the added twist that each train can only move along tracks of its own color. It's probably a bit too complex for a 3 year old, but in one or two years time your daughter would probably be able to solve the simpler levels. The higher levels are quite challenging even for adults.

Comment Re:I have said it before but MMO's need to kill pl (Score 1) 204

So, get rid of it. Create a game with a tutorial area, a mid level and an endgame that kills you. Then you restart the game, skip the tutorial and try a different path.

You can end a character without killing it: in our pen and paper role playing group we've had several characters that retired from the adventuring life. It can be an individual goal that has been achieved (avenged my brother's death) or a group goal (defeated the big evil), but at some point it just makes more sense for a character to settle down than to continue as an adventurer.

It could even be done on a world scale: if all players together defeat the big evil or if one faction defeats the other, the server could be put in "archive mode" where you can still log in and enjoy the views but have no further conflicts to resolve. The players would then create a new character and save a different world.

I think the reason no MMO dares to do this is that such an end of a cycle is a moment at which players will ask themselves whether they want to continue playing in the next cycle or drop out. It's a pity in my opinion, as it reduces the meaning of the player's actions, since nothing ever really changes in the game world. It seems to be a trend in mobile games as well: "games" designed to keep the players busy rather than give them memorable experiences.
