No because I drove each way without filling up during the drive (ie I filled up once in Sacramento and once in San Diego). That's a 500 mile trip. If I was getting 29 mpg, I'd have to fillup in LA, which I didn't do.
Of course they're YMMV because it's completely dependent upon how the car is driven. For example my MkV Jetta is rated at 29 mpg highway. However my best was 46 mpg from Sacramento to San Diego and back (that's right, 46 mpg from a 5 cylinder petrol engine). I even tried to enter this on the EPA's website (fueleconomy.gov) but it wouldn't let me because it said it was too high.
PC = personal computer. Also, running Windows isn't theoretically impossible, just very very slow if via emulation x86 (not least of which is due low memory and swap thrashing). Or you could get the source code for the ARM version of Windows 8 (which I'm sure the academic person could get) and hack it to work too.
The image rendered is 384 x 384 pixels. MSM 7227 results are 0.70 pps and 1.17 pps/GHz. Raspberry Pi is runnying at 700 MHz, so it should theoretically get 0.82 pps. Its possible (and fairly easy) to split up the rendering among all the CPUs in this cluster with some custom scripting, so this benchmark image could theoretically render at 52.42 pps. That Core i5 2400s I mentioned above renders at 235.18 pps!
The ARM v6 processor took more than 2 days to render something that takes 10 minutes on a Core i5. So, "supercomputer" this cluster is not.
* You may say, "Hey, this test is running using soft-float! If you used hard float, it'd be faster!" Well, you would be right that it would render faster under hard float, but this processor still wouldn't finish rendering in less than a day, let alone come anywhere close to Core i5 or Cortex A9.
Agreed. I have an LG Phoenix (aka Optimus One). It is rather underpowered (ARM11 processor is very slow). I found a CM10 rom and put it on. Sure enough it works, and works well - just as snappy as Android 2.1 that it originally shipped with.
I have CM9 running on my Nook Color just fine (for varying degrees of "just fine"). It's certainly more resource intensive than CM7, and the slowness of the Cortex A8 shows.
Cortex A8 is very slow, slower than a Pentium 3 at lower clockspeeds. Cortex A9 is significantly faster, at least on par with a Pentium 4 at the same clockspeed
Don't be fooled by the processor speed. If it's a Cortex A8 or earlier, then the CPU is reallyslow.Cortex A9 is considerably faster at the same clock rate because it is out oforder (and probably better memory controller)
This comes from pork, so don't eat undercooked pork. Tapeworms, in general, come from raw/undercooked meat. Pigs just happen to harbor the ones that sometimes go to person's brain.

Depends on the power plant. Nuclear, hydro, geothermal, wind, and solar (which California has varying degrees of) don't really generate air pollution.
BTW as an SGH-1777 owner, thanks! Running a CM10 without issues.
I'm rather surprised by this. Didn't cyanogen get hired by Samsung? Why aren't Samsung's open source releases and documentation better?
But did they also make robot dogs as a robotic bee launching platform when they bark???
If there's x86 software that you need to run on your phone, you're doing something wrong.
It would probably be next to impossible to write an entire modern operating system, web browser, or word processor in assembly language.
Here you go. It's pretty impressive for something written entirely in assembly .
Hmmm... (it was funnier before the iPhone 5's debut).
The second thing I do is install Cyanogenmod. The first thing I do is make sure the device works (sucks having a new cellphone that doesn't work).
Also Spain. I know a guy who has a locked Samsung Galaxy S II from Orange España.
Does he know anything about camp crystal lake?
What good is apathy if nobody knows just how strongly you don't care?
No kidding. In other news area man constantly mentioning that he doesn't have a TV.
Povray 3.6 is single threaded, so all results are single threaded.

Forgot to add the following:

Unfortunately, the term "supercomputer" isn't really being used properly. They built a cluster of computers, sure. But "supercomputer"??? Hardly. The Raspberry Pi uses a processor based on ARM v6. Lemme give a single-threaded rendering comparison (Povray 3.6 running the benchmark scene (here's what the benchmark image output looks like) with my old HTC Aria, which uses a Qualcomm MSM 7227 processor and has similar processor specs as the Raspberry Pi (ARM v6 + VFP2 floating point hardware):
HTC Aria (MSM 7227 @ 0.6 GHz) *

Render Time: 57 hours 31 minutes 41 seconds (207101 seconds)
Total Time: 58 hours 26 minutes 33 seconds (210393 seconds)
For comparison, here's a faster ARM processor from my Samsung Galaxy S II:
Exynos 4210 @ 1.2 GHz (ARM Cortex A9),
Debian 7.0(armhf), gcc 4.6, -mcpu=cortex-a9 -mhard-float -mthumb -mfpu=vfpv3 -ffast-math -funsafe-math-optimizations

And here's from an Intel Core i5 2400s @ 2.5 GHz:
Core i5 2400s @ 2.5 GHz, Ubuntu 12.04, gcc 4.6, -march=corei7-avx

Almost nobody. However, Park Chan Wook (the guy who directed Old Boy) did shoot a film using several iPhone 4 devices.
Well, why not? Put Cyanogenmod on it once it's been rooted and it'll work as well as any other 7" tablet.
Virgin Mobile uses Sprint's network, so that means CDMA.
