OpenSSL has a functionality: to provide high security. If it fails to do that, it loses all reason to exist, regardless of how efficient the code is.
Also: allocation does not tend to show up in profiling.
Last, note that allocation was deemed slow on SOME PLATFORMS.
Way to go: completely compromise the security on all platforms because you think that on some platforms allocation is slow.

If the two engines rev at different speeds, the whole plane will start to roll, faster and faster.
Consider this scenario:
Engine 1 stalls.
Engine 2 has its throttle stuck at wide open (Aircraft engines do this e.g. when linkage breaks: full throttle is safer than no throttle.)
Then the pilot will die a horrible death EVEN BEFORE HITTING THE GOUND.

You can do this with electric engines, not with IC engines.
It's a death trap, and it will not fly.

It does well for on-screen benchmarks, because of the low resolution of 1280x720.
For on-screen tests, it will have to process fewer pixels than the more expensive models with high-res screens.
This makes it look faster than it is, as you can see by the off-screen benchmark results.

That word does not mean what you think it means. In fact, kernel dbus is probably the most microkernel-ish feature I've seen added to the Linux kernel (although I haven't been paying close attention).

From wikipedia:
Traditional operating system functions, such as device drivers, protocol stacks and file systems, are removed from the microkernel to run in user space.

My previous apartment had a bathroom without conventional heating.
You could still make the bathroom warm enough with the lights above the mirror though.
Six bulbs of 60W gave me a nice and cosy 360W heating, which is actually not that bad in a small bathroom.
If you remember to turn on lights an hour before your shower (in the winter), you would be fine.

My new place has heated floors in the bathroom, so I no longer care.
But for some people, 60W bulbs are nice.

The effect of selling is less than you think.
mtgox is not the biggest exchange, but it can easily do a $1M exchange without affecting price in a too dramatic way.

The nice thing is that their bid book is open for every one to see, so you can predict what happens to price at large orders.
See: http://mtgoxlive.com/orders
At the time of writing, a $1M sell or buy would move the mtgox exchange price 5% in either direction.

If you sell in the largest exchange in the world, which I understand is in China, it would move the market less than this.

If 10 people with 1000 bitcoins each now went to MtGoX and wanted to cash in their bitcoins, what would that do to MtGoX? I think they'd be fucked.

Seriously, this is empty speculation and there isn't the actual money invested in bitcoins to support this increase in face value. The system is fucked. Theres no way the bitcoins in circulation today could actually be cashed in for actual money.

Due to the open nature of the bid book at MtGox, you can see EXACTLY what happens at a sell of 10k btc.

At the time of writing, it would drive down the price to $800,- roughly.

My line of reasoning is such: credit is necessary for the functioning of the modern world. A world dominated by Bitcoin will still have credit. Credit without regulation would be disastrous. Banks cannot be expected to self-regulate properly. A regulatory agency would be in charge. This regulatory agency would then have control over the amount of money in existence. And then we are right back to square one, in terms of the government's involvement in money.

Good point.
There does seem to be some catch22 here.

Still: how did the economy of the 19th century work though?
Bank notes were still linked to gold that was in the bank's vault.
They seemed to make it work.
As a matter of fact: US economy did extremely well in 1800s, where pretty much every year, there was deflation instead of inflation.
Most years, you would get more for your dollar than previous year.
Translate that to the hypothetical 2030 economy where the gold is replaced with bitcoins, would it not be able to function?

Small is beautiful.
