Comment Re:Optimists vs pessimists (Score 1) 158

And they overvalue the effect that their optimism or pessimism will have on the outcome.

My mom used to tell me that "worrying will not change the outcome one bit". The same goes for optimism.

Of course, my mom also told me that I could be whatever I wanted to be, and Daniel Craig got to be James Bond and I didn't so what did she know, right?

With turbo boost, it runs until it hits a thermal limit, then scales the clock speed back a bit at a time until the load stops or it hits a speed at which it can run continuously without overheating. So it almost certainly will eventually throttle back to a lower clock speed, but that may or may not be 1.4 GHz. For example, if you are running only one core at full throttle, it will probably not scale back that far.

But no, it almost certainly cannot run at 2.7 GHz 24x7.

They coat the chips in some sort of coating that insulates them.

My first inclination would be to get the biggest heat sink I could find, fasten it to the motherboard, and build a 12V to 5V and 3.3V DC-DC converter (and 1.8V, if needed). By not starting from 110VAC, you can cut the PSU heat to a level that might be manageable without fans. Then get extension cables for any connectors that you want to keep usable, along with a couple of heavy gauge wires for your 12V leads, stick the whole thing in a plastic box or bag with the cables hanging out the top, and fill it with epoxy....

Mind you, such an approach is almost certainly not advisable, but that would be my first inclination. :-D

Because everyone writes absolutely perfect code, no one ever loses anything, and there are no exploits out there.

No, because there is a difference between looking for the perfect castle and realizing that maybe having a wall isn't so stupid and closing the door and night isn't a bad idea, either.

Making brute force attacks difficult is not a question of perfect code. It's a question of not allowing unlimited tries at unlimited speed (online) or not storing unsalted password hashes (offline). It's not a matter of protecting your server from compromise. A serious defense strategy always includes the assumption that several layers of your protection fail and you should still not suffer a total defeat.

you'd better hope they're salted with a strong salt, per-user, and hashed with a function like bcrypt or PBKDF2.

You see, this is the point. Whether or not they are is not a matter of hope like rain and sunshine. It's something you actively control.

There aren't any magical solutions.

No, but there are good and stupid solutions, and it's time we stop using the stupid ones. It's a feature of this anarchy we love so much, because if software was a car... well, at least in the western world you can't legally sell a car without brakes anymore.

As many folks have already pointed out in other threads on the subject, Intel screwed up the Haswell line by using an entirely different pinout on the i7 than on the i5. The result is that any motherboard with soldered-on chips has to be specifically designed for one or the other.

Apple chose the i5, presumably because that's the hardware grade where most of the Mini's sales came from, rather than doubling their R&D cost by building two very different motherboards.

Here's hoping Intel doesn't screw up Broadwell in the same way.

Scientists Engineer Cancer-Killing Stem Cells 46

A reader writes with news that medical researchers from Harvard Medical School and Massachusetts General Hospital have successfully cultivated stem cells that will kill brain cancer cells in mice without damaging healthy cells. "They used genetic engineering to make stem cells that spewed out cancer-killing toxins, but, crucially, were also able to resist the effects of the poison they were producing. ... In animal tests, the stem cells were surrounded in gel and placed at the site of the brain tumor after it had been removed. Their cancer cells then died as they had no defense against the toxins (abstract)." The next step in the research is to try the treatment on humans. Chris Mason, a professor of regenerative medicine, said, "This is a clever study, which signals the beginning of the next wave of therapies. It shows you can attack solid tumors by putting mini pharmacies inside the patient which deliver the toxic payload direct to the tumor. Cells can do so much. This is the way the future is going to be."
