If you're willing to lose your AC during the hottest part of the day, then you might as well not have AC at all. So there's no reason to get such a device, you might as well just sell your AC.

"Pre-cooling" a house does not work. In the hottest part of the day it was enough of a challenge for the AC to just keep up.

I once lived in Iowa when I lived in the US, and my then-spouse signed us up for one of those programs without consulting me first. I just came home one day and the AC was no longer operating when it was hottest. Utterly, utterly miserable, and I had to wait weeks to get the thing disconnected. Why would anyone willingly choose to have one of those things in their home?

Comment Re:Yes, Because Optical Media Is Durable (Score 1) 294

I have a stack of CD-Rs I burned back in 1996 which are still readable, and I pulled a file for a MMO from some CDs I made back in 2000. The info is obsolete, but it is still present on the media. The trick back then was to run Linux and cdrecord, with as few items running in the background as possible, just to ensure there would be no buffer underruns since there wasn't any protection against that back then.

I would say it really depends on the media for archival life. Some optical media is junk, other media will last for a very long time.

The bottom line is that the "conservatives" advocating abstinence training are actually right. The only actual way to reduce teen pregnancy is to encourage them to stop fucking so much.

That's like saying the most effective way to stop the tide coming in is to stand on the beach and tell the tide not to come in. I mean it works perfectly when it works.

But much like the tide won't stop when you tell it to, there is nothing you can say to teenagers to stop them fucking.

Back to your stats, condoms are pretty effective when used correctly--98%, not 82%. When used badly they have high failure rates. The CDC data indicates that you should be telling teenagers how to use condoms properly.

I'm a centrist. I believe in birth control and sex ed for all children.

However, before today's results, I would have thought the robot baby IN ADDITION to sex ed and teaching about birth control was a good idea. I've not read the nitty-gritty of Australia's tests. (Are the robot baby girls getting less Sex Ed teaching) so I won't rule out Robot Babies as a viable option- it certainly shouldn't replace learning.

I'd be interested in knowing WHY the robot babies failed. Do the girls consider the experience "not that bad". Do they think "I've done it with a robot, I can handle my own child". Or is it simply that they didn't receive as good sex ed teaching as the control group?

Indeed, many people have pointed this out over the last couple of articles on this subject. So they could just as easily turn off the game altogether to prevent drivers pretending to be passengers.

In reality, the deaths here are the drivers fault not the games, but if the death count racks up this will eventually result in a lawsuit and fines for the developer. The moral thing for them to do is disable the game when the phone is moving fast to prevent asshat drivers hitting people. It also might be the best economic move for them- if they end up getting hit with massive fines from a government somewhere in the world that want to blame deaths on the game instead of the driver it could be crippling.

Most countries probably won't blame the game developers they will blame the driver; however, I guarantee there are some countries in the world that WILL blame the developer.

On a 8-core machine, a processor will be placed into a wait queue roughly 7 out of 8 times that it needs access.

You just snuck into your analysis the assumption that every core is memory saturated, and I don't think that all the memory path aggregates in many designs until the L3 cache (usually L1 not shared, L2 perhaps shared a bit). The real bottleneck ends up being the cache coherency protocol, and cache snoop events, handled on a separate bus, which might even have concurrent request channels.

I think in Intel's Xeon E5 line-up there are single-ring and bridged double-ring SKUs for forwarding dirty cache lines from one cache to another (and perhaps all memory requests). This resource can also drown for many workloads.

In many systems, you have all these cores running tasks which are fairly well isolated (not much cache conflict), except they all want to be able to allocate as much memory as they need from a giant memory space (e.g. a TB of DRAM) so they fundamentally have to fall through to a shared memory allocation framework.

You can learn a lot about the challenges involved by following the winding path of something like jemalloc as increasing concurrency levels expose yet another degeneracy.

The real problem with this field is that there isn't a single, simple story like the one you tried to tell. There are usually dozens of ways to skin the cat, each with completely different scaling stories, with different sets of engineers who are good as tweaking or debugging those stories.

At this point, what you have is a fragile coordination problem between your solution space, your architecture, and the engineers you employ, forcing ambitious ventures to crack out the golden recipe: pour in seven cement mixers full of head hunters, one 55-gallon oil drum of exclamation marks, a metric butter tonne of job perks, and agitate appropriately.

I think scientists can make some larger statements on the impacts. No one can tell you what exactly it would be like at any particular location, But what you're doing is exaggerating the amount of uncertainty, and then trying to defend warming trends by invoking even less certain predictions. It's hard not to see how you aren't just being a contrarian simply because you don't like the answers science can provide.

When rain belts shift northward in North America, arid conditions will begin to become the norm in large parts of the American Midwest, and that will mean American food security will become, at some point over the next century so, one of the most serious issues the US has ever had to face. And this isn't a matter if whether it will happen or not, the debate is over WHEN it will happen.

Pumping vast amounts of formerly sequestered CO2 into the atmosphere is just plain bad. We should be moving at all speed to alternative energy sources, and either leaving the oil and coal in the ground, or finding some other use for it that doesn't involve releasing CO2 into the atmosphere.
