The Crucial M500 has them as well. I wish there was a list of drives which have been verified to not suffer corruption because of power loss during writes.
The USB Flash drives I have tested only scrub on reads and writes. Whether the drives were powered or not did not affect retention which was months when new (at room temperature).
I assume that SSDs perform scrubbing while powered. I would like to know if Compact Flash and SD cards do but my guess is that they do not.
I agree that it is a strong word but if they were not soldiers, police, marshals, or any other type of law enforcement, then what were they? What do you call citizens who defend the nation? They performed their function despite being disarmed by the government that they protected, while lacking regulation which Congress did not provide, and against the recommendations of the government to not interfere and to go along with the demands of the hijackers.
And the lesson we learned from that is that we need more professional government to protect us.
When I say that I have not seen it pan out, I mean that I use engineering applications which should be able to take good advantage of heterogeneous computing with a unified address space as implemented in AMD's recent APUs but none of them do and AMD's existing APUs come with a significant cost in single thread performance. If I just wanted video acceleration and processing, then the existing PCIe interface GPUs can do that.
Failing this we have baseband processors with full read write access to OS memory to reduce material costs. I would be surprised if there was a consumer baseband on the planet without capability of being field "upgraded" by Agent Smith... at least from various accounts of ancient feature phones being turned into bugs.
The baseband system needs to be considered compromised and hostile.
I have a feeling the bigger issue with ubiquitous encryption for TLAs is that when everyone uses encryption then the ability to use the fact that encryption was used to justify suspicion evaporates... that's what I think they are really afraid of.
The other concern I have heard voiced by the FBI is that ubiquitous encryption would prevent dragnet data collection which I assume means that they are collecting more than just metadata already and relying on parallel contruction to hide it.
I came to say the same thing. How awesome would it be to be at the beach, realize you forgot a towel, and have one drop in within a half hour...

Juan hesitated. “That's strange.” “What?” “I've got mail.” He set a pointer in the sky for the others to see: a ballistic FedEx package with a Cambridge return address. It was coming straight down, and rom very high up. At about a thousand feet, the mailer slowed dramatically, and a sexy voice spoke in Juan's ear. “Do you accept delivery, Mr. Orozco?” “Yes, yes.” He indicated a spot on the ground nearby. All this time, William had been staring into the sky. Now he gave a little start and Juan guessed the guy had finally seen Juan's pointer. A second after that, the package was visible to the naked eye: a dark speck showing an occasional bluish flare, falling silently toward them. It slowed again at ten feet, and they had a glimpse of the cause of the light: dozens of tiny landing jets around the edge of the package. Animal rights campaigners claimed the microturbines were painfully loud to some kinds of bats, but to humans and even dogs and cats, the whole operation was silent.... until the very last moment: Just a foot off the ground, there was a burst of wind and a scattering of pine needles. “Sign here, Mr. Orozco,” said the voice. Juan did so and started toward the mailer. William was already there, kneeling awkwardly. The Goofus spazzed at just the wrong instant and lurched forward, putting his knee through the mailer carton. Miri rushed over to him. “William! Are you okay?” William rolled back on his rear and sat there, massaging his knee. “Yes, I'm fine, Miriam. Damn.” He glanced at Juan. “I'm really sorry, kid.” For once, he didn't sound sarcastic. Juan kept his mouth shut. He squatted down by the box: it was a standard twenty-ounce mailer, now with a big bend in the middle. The lid was jammed, but the material was scarcely stronger than cardboard, and he had no trouble prying it open. Inside... he pulled out a clear bag, held it up for the others to see. William leaned forward, squinting. The bag was filled with dozens of small, irregular balls. “They look like rabbit droppings to me.” “Yes. Or health food,” said Juan. Whatever they were, it didn't look like William's accident had done them any harm.
Whenever a Nerf dart landed in my coworker's cube, he would keep the dart and tell the person who lost the dart to go pound sound. I can see the same thing happening to drones that crash into his backyard. That's a nice drone you lost, too bad you're not getting it back.
I'm going to go out on a limb here and say it may very well be technological limitations, not operator limitations. I'm thinking that there is probably some lag in the feedback. Whether or not this can be fixed is, at least partially, going to be dependent on how far out of site the drone will be.
While lag in feedback is problematical if latency is high, this is completely solvable and more of a problem with digital video and digital control systems if they are not optimized for low latency. Lag in simple radio control systems is dominated by mechanical servos and the same is true if low latency digital protocols and communication channels are used.
The problem I have seen involves the short time constants produced by linear-square-cube scaling; the special effect movie guys face this when trying to make small models look real especially when water is involved. With large vehicles, inertia is high so human reaction times are not a problem and can be used within the control system feedback loop. The solution (I am simplifying here) is active control to make a small vehicle react to operator control like a large one. I have seen this done with simple radio control models by adding mechanical gyroscopes.
In this case, the Supreme Court has upheld (see Heller [wikipedia.org] ) the rights of citizens to own and keep small firearms (which, other than the material used to manufacture them are materially similar to Liberator) under the second amendment.
But oddly enough not the design of the Liberator which lacks rifling making it a Title II AOW (any other weapon) with significant restrictions on ownership. It is outright banned in many states.
BATFE has already moved to add restrictions on gunsmithing so I figure it is just a matter of time before they or Congress goes after printed firearms. If they follow the model of the NFA, it seems unlikely that the court would strike it down.
Nice straw men. Try comparing murder rates between Europe where guns are hard to get and the U.S. where guns are easy to get. Comparing U.S. cities is just silly.
Or compare homicide in the US with different types of weapons like knives. Is our proportionally high rate of homicide by knives the results of our lax gun laws?
Decades of civil assets forfeiture and cops making up PC and RS with the judicial branch looking the other way has not produced any change. Parallel construction will hide the increasing number of 4th amendment violations preventing review.
The court ruling is largely moot for two reasons: the law will be expiring shortly and the NSA can justify their actions based on other things like Article 2 executive powers.
When that next truck bomb detonates at a sporting event or mall, or when that next muslim fan goes on an indiscriminate killing spree through a church, know in your heart that you have allowed that to happen.
3 of the 4 planes hit their targets despite government actions. 1 of the 4 planes was stopped by the militia who ignored government orders to not interfere. Who was more effective?
How many mass shootings have been stopped by civilians?
Just look at how the 4 Swedish police officers in New York handled the situation. They were unarmed and were calmly holding the subjects. If this were the NYPD, do you think they would have handled it the same way, or would they have used much, much more force?
If the NYPD had handled it, the suspect would have resisted arrest more.
It has been shown police do not follow the law hell even use ignorance of the law as an excuse.
The Supreme Court recently upheld this; ignorance of the law is no excuse for a civilian who is arrested but it *is* an excuse for the cop making the arrest.
Here in Missouri cops use our seat belt law to pull people over when they want even though it is a secondary offense and the statute specifically states that it is unlawful to pull people over for just a seat belt infraction.
Being a hardware guy, I would have tried either pinning one of the ATA I/O bits to corrupt the data during enumeration or disabling the ATA interface until after DOS is booted. Back then I had an ISA ATA interface card which was just discrete logic bus transceivers, buffers, and some simple decoding logic which could do either easily. I used it for debugging ATA interfaces.
The ATA interface was originally a buffered version of the ISA bus with some decoding. You can build one with a few TTL logic ICs.
There is a lot of overlap with the absorption of water and a lot more water in the atmosphere; if the absorption in that band is already large, then a change in CO2 will have little effect. I could do the integration but when I look up the data for the absorption of CO2 and water versus wavelength, I get wildly different curves depending on the source.
Back when I built my workstation I went with the AMD Phenom II 940 because the Intel solution for ECC was a lot more money which was better spent on system RAM and disk performance. The Intel processor, motherboard, and FB-DIMMs would have more than doubled the cost. It is not that bad now but an Intel system still carries a price premium.

The Crucial M500 has them as well. I wish there was a list of drives which have been verified to not suffer corruption because of power loss during writes.
Flash memory retention has nothing to do with whether it has capacitor backup and being powered only matters if the drive scrubs itself.
The USB Flash drives I have tested only scrub on reads and writes. Whether the drives were powered or not did not affect retention which was months when new (at room temperature).
I assume that SSDs perform scrubbing while powered. I would like to know if Compact Flash and SD cards do but my guess is that they do not.
The mechanical switches to handle hot swapping would be fun.
These transformers do not fail often enough to justify the expense of the switch infrastructure and a standby transformer.

I get bent out of shape when environmentalism results in rent seeking instead of solutions.
