PLEASE READ THE DESCRIPTION!!

UPDATE 06/10/08
Thanks to everyone who took the time to watch,
vote and comment on this video. I never expected
that the video would be shared this intense. I
just wanted to share this vid and now look what
happened ^^"
So to make things clear:
I am not the original maker of this!!
The fame (if any) belongs to someone else. Neither
do I know the lucky guy nor if he knows that this
was uploaded on youtube (and by now on
gametrailers and a lot of other sites too).
I appreciate any compliment, but please keep in
mind that this is not my work.
If, by any chance, someone knows who to give
credits to, let me know and send me a message so I
can add it here. Thanks for reading!

Fun with an old hard drive. Took the platters out
of many hard drives and put them into one drive.
Spin it up to speed and give it a nudge, then
watch the fun.

| Disk-Based Parallel Computation, Rubik's Cube, and Checkpointing |

Google Tech Talks
March, 24 2008
ABSTRACT
This talk takes us on a journey through three
varied, but interconnected
topics. First, our research lab has engaged in a
series of disk-based
computations extending over five years. Disks
have traditionally
been used for filesystems, for virtual memory,
and for databases.
Disk-based computation opens up an important
fourth use: an abstraction
for multiple disks that allows parallel programs
to treat them in a
manner similar to RAM. The key observation is
that 50 disks have
approximately the same parallel bandwidth as a
_single_ RAM subsystem.
This leaves latency as the primary concern. A
second key is the use
of techniques like delayed duplicate detection to
avoid latency. For
example, hash accesses accesses can be saved
(even saved on disk), until
there are sufficiently many pending accesses to
use standard streaming
techniques. We have designed a library for search
problems that exploits
the high parallel bandwidth while hiding the
latency. We build
abstractions for search that employ parallel
disk-based hash arrays
with the same speed as a single hash array in a
single RAM subsystem.
In the case of Rubik's cube, we exploited this
mechanism by using
seven terabytes of distributed disk in a search
problem that showed
that 26 moves suffice to solve Rubik's cube. Our
initial efforts
emphasize idempotent operations, so that we can
easily recover from
hardware or software faults. We next intend to
apply a more general
solution for fault recovery: checkpointing. This
separate effort
in our lab has now produced a mature, robust
user-level checkpointing
program has now matured. The package works
successfully in tests
on OpenMPI, MPICH-2, OpenMP, and parallel iPython
(used in SciPy and
NumPy). Our DMTCP package transparently
checkpoints parallel,
multi-threaded processes, with no modification
either to the
operating system or to the application binaries.
Extrapolating
from current experiments, we estimate that we can
checkpoint a 1,000
node parallel computation in a matter of minutes.
We are currently
searching for a testbed on which to demonstrate
this scalability.

| Vertical Axis Disk Wind Turbine |
 |
How the turbine works: Rotatable shutters mounted
on a circular disk automatically open when
directed into the wind, irregardless of the wind's
direction. Pairs of upper and lower shutters are
geared together. The lower shutter acts as a
counterweight to the upper shutter. The bottom
shutter opens in the downward direction and its
weight helps to lift the upper shutter in the
upward direction, as the wind applies an opening
force against both shutters. When the shutters
reach the vertical position, stops prevent them
from opening further and the force of the wind is
transferred from the open shutters to the circular
disk. And the circular disk is attached to the
vertical axis for power output. The circular disk,
shutters, and outer vertical axis rotate together.
The outer vertical axis is mounted via bearings
over an inner vertical axis that is stationery.
The shutters are blown closed by the wind (no
stops in the opposite direction) as they reverse
direction during their rotation and move into the
wind on the opposite side of the wind turbine.
When the wind is not blowing, the shutters open by
gravity because the lower shutter is weighted to
be slightly heavier than the upper shutter and it
therefore can cause the upper shutter to open via
the force of gravity as the two shutters are
geared together. Wind blows against the open
shutters and the open shutters with stops apply a
force against the disk, but the open shutters with
no stops (opposite side going into the wind)
merely close due to the force of the wind (not
applying a force against the disk) and the wind
turbine begins spinning no matter what direction
the wind comes from. Operation of the turbine is
remarkably quiet as compared to the appearance of
the video due to biasing members that absorb the
shock of the opening and closing and provide
useful energy output.

Based on a true floppy.
I don't like cleaning but my momma makes me
anyway.
She said, "I'm sick of this crap, boy you gonna
clean the house today."
She said, "I'ma go to the store and when I come
home it betta be done."
I said, "No problem, ma, I'ma pick my shit up one
by one."
When she walked out the door I started cleanin'
like she said.
The only problem is I am easily distracted.
I started cleaning shit 'til something shiny
caught my eye...
it was a plastic square with dimensions of 3.5.
There's a floppy disk on the floor,
There's a floppy disk on the floor,
Baw.
There's a floppy disk on the floor,
There's a floppy disk on the floor,
Oww.
There's a floppy disk on the floor,
There's a floppy disk on the floor,
Aow.
There's a floppy disk on the floor,
There's a floppy disk on the floor,
Click.
Next thing I knew, door flew right open,
she came in with groceries.
Oh no all I did was sing this song,
maybe I have ADD.
She pointed fervently at all the mess
her eyes ablaze.
But then she froze right there
when something shiny caught her gaze.
I'm sure it wasn't hard
to see how little I had done.
But then she looked at me
and then we sang in unison.
There's a floppy disk on the floor,
There's a floppy disk on the floor,
Baw.
There's a floppy disk on the floor,
There's a floppy disk on the floor,
Oww.
There's a floppy disk on the floor,
There's a floppy disk on the floor,
Aow.
There's a floppy disk on the floor,
There's a floppy disk on the floor,
Huah!
So it was we stood right there
just singing that repeatedly.
The only explanation is
that it was destiny.
Or maybe black magic,
but we all know that don't exist.
I guess I'll sing the chorus
one more time if you insist.
There's a floppy disk on the floor,
There's a floppy disk on the floor,
Baw.
There's a floppy disk on the floor,
There's a floppy disk on the floor,
Oww.
There's a floppy disk on the floor,
There's a floppy disk on the floor,
Aow.
There's a floppy disk on the floor,
There's a floppy disk on the flo hooaahh.
There's a floppy disk on the floooo...
Wa-naw.
