Not to mention he wasn't the genius behind Apple. Steve Wozniak was. In fact in numerous interviews about all Steve Jobs had a hand in in actually designing the original Apple computers was insisting that the power supply be a certain color for aesthetics. The real work was done by a man whom half the nation probably has no idea exists.
Woz is the genius behind the original Apple products from decades past, and Jobs is the genius behind the consumer electronics and publishing juggernaut that Apple is today.
Not really. The real geniuses are the engineers and the designers. The difference between the Apple II days and now is that decades ago the engineers and designers were far more visible or well known. The Apple II and Woz being at one extreme, however the original Mac had the designers/engineers names molded into the interior of the case. Jobs, then and now, stands on the shoulders of the engineers and designers.
Best wishes for Jobs. Hopefully he just has to slow down and relax.
Yeah. I had some mental image of the memory being inside a sealed enclosure with an external PCB only handling the interface (SATA, etc). Now that I take a closer look I see that the enclosure is not sealed and that the interface and memory are all on the same PCB. Make more sense for cooling and of course cost reduction.
Encrypting it? Is taking data off really an issue anyway. If it's confidential data, destroy the disk when you need to dispose of it. Not repurposing or re-selling hardware with sensitive information on it sounds like a no-brainer.
Also if its so hard to delete then maybe SSD drives are a good place for long term backup/storage of those encrypted volumes. Just wondering, not claiming it is so.
Someone once told me that I should use RSA encryption because it was developed by the NSA. I thought to myself "why would the NSA produce and give away an encryption algorithm they can't break". I concluded that they wouldn't. So yeah, probably not secure.
For the sake of argument lets assume the NSA can break it. So what? The government already has my SSN, bank account numbers and credit card numbers. I only need to stop the thieves, finder keepers, dumpster divers, computer recyclers, etc.
Or in a microwave. That seems to destroy the gates on the chip. 10 seconds on High should be enough. Just be sure to only place the PCB and not the entire drive as they can contain lots metal.
And why can't an attacker just attach a good PCB from a different drive of the same make/model? Assuming of course that the attacker is targeting you specifically and is not just a dumpster diver / recycler who sees a drive and wonders if it works and what is on it. Just removing and breaking the PCB is fine for the later. Although it wouldn't hurt to repeatedly drop drives from 6ft onto concrete until they land flat and rattling noises begin to come from inside the drive.
You know, I've never understood this one. If you have written a zero to every sector on the hard drive, including the hidden space, how in the world is it possible to recover any data at all?
Because digital is just a convenient abstraction for our analog reality. Here's a gross simplification. A bit is just a magnetic blob on a large plane of magnetic media. When a read/write head returns to a particular spot it does not return to exactly that same position, close but not exact. As the platter spins and it lays down a track of these magnetic blobs it may write the new track a little bit to the side of the old track. This partly motivates wiping software writing data seven or more times, it wants to increase the likelihood of getting the old data.
Try this: Take two hilighters, one yellow and one a darker color. Draw a yellow line. Now draw on top of that line with the other color. See any pure yellow peeking through on the edges? That yellow is like the area where data recovery people will use highly specialized equipment to read "overwritten" data.
It was good but I can see that it would never have been a hit regardless of R or PG-13 ratings. It just did not have any sort of mass appeal. Blaming its lack of success on the R rating is just a cover story for the real problem.
From SCIENTIFIC AMERICAN , November 1998, Page 26:
Others insist that NT was not the culprit. According to Lieutenant Commander Roderick Fraser, who was the chief engineer on board the ship at the time of the incident, the fault was with certain applications that were developed by CAE Electronics in Leesburg, Va. As Harvey McKelvey, former director of navy programs for CAE, admits, "If you want to put a stick in anybody's eye, it should be in ours." But McKelvey adds that the crash would not have happened if the navy had been using a production version of the CAE software, which he asserts has safeguards to prevent the type of failure that occurred.
The mishap has provided ample ammunition to critics of Smart Ship, including contractors and navy staff whose livelihoods might be jeopardized by increasing reliance on commercial off-the-shelf (COTS) products, such as NT. "There's a faction in the navy that doesn't want Smart Ship to be successful," asserts Trey McKay of Intergraph, a supplier of Pentium-based PCs to the military. Indeed, Smart Ship upsets the cozy relationship between the Department of Defense and certain suppliers that have exacted premium prices for systems designed especially for the military.
Actually the navy officers on board the ship at the time of the incident said it was not windows, rather it was an application that controlled propulsion. The developer of this software also admitted it was their software, although it was a development version not the production version that would have handled the fault more robustly.
Alright, just for the sake of argument, supposing it *was* Windows that caused the fault and not the application. Do you really think the United States Navy is going to publicly say that Windows caused this huge expense and embarrassment?
What expense and embarrassment? The ship was a development platform at the time, not an operational ship. The testing they were doing was to simulate equipment failures (as in pumps and motors not chips and hard drives). IIRC, when they manually entered data into the database to simulate a failure some of the client applications reading that data crashed. I think they had everything back up in a few hours. So they fed a LAN environment under development unexpected data and found nodes with applications that crashed. Shocking, truly shocking.:-)
The operating system was not involved, it would have happened under unix too.
Not true. Under Unix, it would just have killed the one uncritical process that did the division by zero (the "bad data" was a zero value for a measurement that could/should physically not ever be zero), and would have left the processes controlling propulsion and all the rest alive.
You are assuming that the processes controlling the equipment did not do the divide. Furthermore, NT works as you describe. One process misbehaves and is terminated but the others continue, NT and Unix are similar in this manner.
and a windows crash left a ship dead in the water.
Actually the navy officers on board the ship at the time of the incident said it was not windows, rather it was an application that controlled propulsion. The developer of this software also admitted it was their software, although it was a development version not the production version that would have handled the fault more robustly. IIRC a speculative article by a unix advocate who was not involved in the project and who was not on the ship made the original claims against windows. Linux advocates ran with this early speculation and it has become urban legend.
Yea, and at-least 2 of them were shutdown by windows crashes and were dead in the water, need a tow all the way back to port.
Thats urban myth. IIRC the original article that claimed that Windows was to blame was debunked. The original article was based primarily on speculation from a unix oriented developer who had not worked on the project and who was not on the ship. The publisher of the article backed away from it. The Navy officers who were on board at the time said it was the application software that controlled the propulsion system. The developers of this application software said it was their fault, although the software was a development version that did not contain the safeguards the production software would contain. Basically bad data was entered into a database, this was fed to the application that controlled propulsion, and this application failed. The operating system was not involved, it would have happened under unix too.

Maybe people reading history textbooks should get a pass and be allowed to read. There seems to be some need. I get the attempt at humor and any and all politicians are fair game. But perhaps Bachmann did something few expected and actually made an accurate historical reference.

"Adams was elected a U.S. Representative from Massachusetts after leaving office, the only president ever to do so, serving for the last 17 years of his life with far greater success than he had achieved in the presidency. Animated by his growing revulsion against slavery, Adams became a leading opponent of the Slave Power and argued that if a civil war ever broke out the president could abolish slavery by using his war powers, a correct prediction of Abraham Lincoln's use of the Emancipation Proclamation in 1863. Adams predicted the dissolution of the Union on the slavery issue, though he mistakenly predicted that if the South became independent there would be a series of bloody slave insurrections.[" http://en.wikipedia.org/wiki/John_Quincy_Adams
The naval gunfire I'm referring to was ship to ship, not shore bombardment. I believe many of the ships sunk around Guadalcanal were sunk due to ship to ship gunfire. I agree that aircraft did most of the sinking in the pacific war in general, and that submarines probably came in second, but the campaign around Guadalcanal were a special case where lots of ship to ship gunfire occurred. The US Navy withdrew the carriers from the immediate vicinity of Guadalcanal to protect them. The US ships that remained there and also sailed north to intercept enemy resupply and reinforcement of Guadalcanal were destroyers, cruisers and sometimes battleships. Much of the fighting was at night and at close range. A long but informative read: http://en.wikipedia.org/wiki/Naval_Battle_of_Guadalcanal
I have no idea why Pier1 asks me for my zipcode every time I buy something small like a mug or a pillow. And I pay cash most of the time. How are they able to sell that information?
They are not profiling you, they are profiling your neighborhood. They are probably trying to figure out what neighborhoods they should spend their ad money in, or trying to measure the response to advertising in neighborhoods.
I'm not sure I like this. In california I've had the pumps at gas station ask for my zip code rather than my PIN. At some stations I think I'd prefer to only provide a zip code.

My only question is... why can't the States involved fund this? What benefit do the people in Kansas get from this high speed rail? Why are they paying for part of it?
Why does any level of gov't have to build rails? Why not repeat what worked in the past? Grant the land to a private concern who will privately invest, build and operate. Gov't really only needs to regulate not build. For example grant a 100 foot wide strip of land between Los Angeles and Las Vegas and I bet the casinos will find the money for two high speed tracks.
Selling bonds does not disprove the original poster's claim of "spent all the money". Money is not only created by the printing of bills, sometimes it is created by the selling of newly created bonds.
Also countries and banks buy bonds too, they are not just for "rich individuals".
basic economic data is that when countries are in a recession, they should increase government spending (especially on infrastructure like rails).
You are taking a good theory and misapplying it. Infrastructure spending is usually better timed when periodic economic downturns occur but it is erroneous speculation to say that rails are the better project, more so for high speed rails. There are far more important things than rails: water, sewage, bridges, roads,... maybe electrical too. All of these are in serious need of attention. Only after these are addressed would rails become a reasonable project. Right now rails just seem to be a pet political project.
This might work for the bigger pieces that are easier to dodge, but what about all those smaller pieces that are much harder to track and evade? Is it possible to build a huge array of the gel that they used to collect fragments and dust from comets and use that to collect a lot of the much smaller pieces? Or are there some technical limitations to this, such as the debris having such a high velocity that they'd just punch right through the gel?
Given the velocities a small object may be more likely to vaporize. I think the problem would be with the gel or foam losing material during impacts. Are we replacing one bit of debris with multiple bits? At orbital velocities a piece of gel or foam, or a blob of water, is quite dangerous.
The probes that collect fragments and dust maneuver to and match velocities with the target to a degree that the material can withstand the impact and be captured. They are not just put in a collision path and take a full velocity hit.

Because on an SSD the data goes with the PCB.
Yeah. I had some mental image of the memory being inside a sealed enclosure with an external PCB only handling the interface (SATA, etc).
