I recall a plan from waaaay back in the 1980's of equipping the space shuttle with a high pressure water nozzle. I forget the exact details of how it worked, but it was something like the water would turn into a stream of frozen water particles that would hit the debris, absorbing kinetic energy of the debris as it vaoprized...or some such shit.
At the risk of getting people to read some of TFA, here are some quotes from the original article:
They’re “space qualified,” as NASA puts it
“They’re not state-of-the-art spy satellites, but they are probably still state-of-the-art optics.”
The spy telescopes have a feature that civilian space telescopes lack: a maneuverable secondary mirror that makes it possible to obtain more-focused images, said David Spergel, a Princeton University astrophysicist...The new telescopes are “actually better than the Hubble. They’re the same size, but the optical design is such that you can put a broader set of instruments on the back,”
From that I gather that since Hubble point at earth could resolve a dime laying on the ground, and that's not as good as current state-of-the-art spy satellites, that the US government seems to have a need to check our hair for lice from orbit.
Oh, oh... Executive Officers clean up overflowing toilets. Not so they get an appreciation of what is being done, but for the general entertainment of the rest of us!
I saw a conspiracy theory book that claimed he succeeded in building his death ray and that's what the Tunguska explosion really was. It further claimed that Tesla had done it as a publicity gimmick intending to aim it at the North Pole and blow it up right before Admiral Peary could reach the North Pole, but his aim was off!!!
It then went on to claim that Tesla did not die, but instead was living inside the "face pyramid" on Mars with Marconi!!!!
Really? Not even this one? Tesla moved to Colorado to continue his experiments and to stupid lightening. Maybe Matthew Inman should learn to use that Google thingie on the intertubes.
I can see how that might work if it were a pretty old hard drive. Since hard drives have magnetic recording media, you can't just write raw data straight to disk. For example, if you truly wrote all zeros or all ones (the recording bias all in one direction or another) there would be no way to figure out if it were all zeros or all ones or how many bits of zeros or ones that you had recorded. So all data is encoded before writing it to disk to ensure that there is always an alternating magnetic field on the disk. A zero might be expanded to 1001, or something like, that before it is written to disk. Different encoding techniques have certain known data pattern weaknesses, data patterns that when encoded will produce a more difficult to read signal on the disk than other patterns. These bad data patterns are used to test drive designs. Additionally, each data track on a disk is sandwiched between two servo tracks. These help keep the head centered on the data track no matter where it is without having to worry about drive calibration. And finally, drives include a lot of spare sectors that the drive electronics are supposed to automatically swap out, without the OS knowing about it, when bad sectors are detected.
So, it is possible that you had a drive that after a lot of writes and rewrites was having some signal-to-noise ratio problems detecting data written on the drive. Your rewrite operations may have normalized the media on the disks just enough to get a little more life out of it. But what was actually being written to the disk wasn't all zeros. If that were possible, you would really make the drive unusable!
As someone that worked as an engineer in the hard drive manufacturing industry for 15 years I would have to agree, "No."
You might be able to revive a drive if it is a problem with a PCB, but if it is a problem with the disks or heads, forget about it!
Incidentally, a "hard drive crash" used to mean a head touched the disk and physically damaged the head and/or the disk. But for nearly two decades now, heads in hard drives are "contact heads," meaning the smallest part of the gap between the head and the disk is smaller than the mean free path of air molecules. However the heads are "flying" at a fairly high angle of attack, so it is really only the trailing edge of the head that is in contact with the disk at all times. Between that contact head design and auto retracting armatures that pull the heads off the data area of the disks, actual head crashes are extremely rare under normal operating conditions.
I live in an area that is at high altitude, with very dry air, and there is a lot of dust and dirt in the air (not all devices that need fans get to live in a clean room). In such an environment, a spinning fan blade creates it's own static charge which helps bond dust to the blades. I regularly see fan blades with such a thick layer of dust caked on them that you can not see the color of the fan blade material any more.
PadMapper looks pretty much the same as HousingMaps, except that PM is connected to more rental sites than just CL. You click on a link and an overview of the listing is shown is a DIV along with a link to the original listing.
I think rollingcalf has it right. PM just caved. There is little difference between what PM and HM are doing and what any blogger does when they summarize an article from another web site and post a link to the original. Craig's List has no legal standing.
Sounds like it is only in a small subset of versions. From the source article...
"Whether a particular build of MySQL or MariaDB is vulnerable, depends on
how and where it was built. A prerequisite is a memcmp() that can return
an arbitrary integer (outside of -128..127 range). To my knowledge gcc
builtin memcmp is safe, BSD libc memcmp is safe. Linux glibc
sse-optimized memcmp is not safe, but gcc usually uses the inlined
builtin version.
As far as I know, official vendor MySQL and MariaDB binaries are not
vulnerable."
...and pretty sure the old saying is "you can't hack into a server that is unplugged" anyway, or at least that's how I used to say it back in the day. So I fail to see how this story is news at all. Out of band management of one sort or another has been around for decades.

Found an article referencing the water spray idea.

Since over 50% of US electrical production is from coal
50%? More like 40%...

The url *does* have a question mark after the headline!
Christians don't try to kill people over a film? Really?
Exactly! The only thing I ever need it for in a desktop environment is for apps use it, not for web pages.
The real problem, as I see it, would be for all those smartphones out there that use java for everything

Wow.
TheOatmeal is dead wrong...
There is no Tesla Museum in the United States

How about an actual study on Twitter demographics instead of guessing and anecdotes?

Maybe continue using Flash but use Adobe's toolkit to output to HTL5?
Come to think of it... Sandia is in a high altitude, dry, dusty area!

Yup. I laughed when I read this part...
And as the whole unit spins, you aren't going to get dust build up (ever).
I've got a bunch of old, dead fans I'd love to show them...if they could see them through all the caked on dust and dirt!

HousingMaps.com has been doing this for something like 5 years. I'm sure there are probably others like it too.
run of the mill moron that have an overinflated ego
What struck me was his bizarre inclusion of his height and weight in his diatribe. Sounds to me like he is a narcissist!

Nah, the real money is in climate denial "research."
...tell the military that your science project has military applications. Otherwise, good luck getting a grant.

Yes, because something like that could never happen in a democracy, so it must have been a joke!
