Comment Re:Self encrypting hard drives are WORSE! (Score 1) 73


Real SED drives implement this standard, which includes the disk changing the key - it's how Instant Secure Erase works, among other things (old key is thrown out, new key is generated by the hard drive). If the WD product really behaves as described in that link, then I'd agree - that implementation of the controller is flawed (and also, not TCG/Opal compliant, I'd wager). More than likely, the drive inside the enclosure implements the standards correctly (or nearly so), and the problems are in the USB controller side of things. SED drives are not very user-friendly, and WD was probably trying to mask that.

You've clearly never researched how SED drives work. No one has "the key for the drive," it's generated by the drive on the fly. The drive ships unsecured, and when you secure it, it generates a new encryption key using the passphrase you supply. When you Instant Secure Erase the drive, it throws out the old keys and generates new ones. You can revert the encryption settings back to factory default, but you lose all data in the process. On top of that, on the better drives, all of this is reviewed by NIST for FIPS compliance.

Software encryption requires a couple of sufficiently motivated and clever Russians to break. Proper hardware encryption requires far more motivated, clever, and trained NSA engineers.

Comment Re:Summary lesson: Physical access trumps all. (Score 2) 73

With SED drives, depending on the system architecture, the key to unlock them is often stored on the controller (think servers, here). So, if you steal a drive or find a drive in the rubbish bin, etc., you can't access it, but if you get the whole server or the drives + controller, you have full access, nothing else required. The big benefits to SED drives are: 1) MUCH faster than software-based FDE. The encryption basically happens at drive speed, and when you build a larger array, there's no slowdown - the encryption scales with the number of drives, since each disk has its own controller doing the encryption. 2) Instant Secure Erase - this wipes out the encryption keys in the drive's controller, rendering the original data permanently unrecoverable (assuming the encryption itself isn't broken). So, you can dispose of the drive (or RMA it) without worry that your corporate secrets are going to float out into the world. So, expensive "keep your hard drive" support plans can go away, as can expensive drive shredding services.

It probably depends on the hospital/clinic. Where I was, they asked for payment when I left. They didn't ask for evidence of my ability to pay when I arrived, about to collapse and puking on their floor. They treated me first (for a full day), then asked for payment. Contrast that with a trip to the ER I had in the US, where I had just been stabilized after anaphylaxis from an allergic reaction. While I was still being wheeled back, they were asking how I was going to be paying for that, if I had insurance, etc., trying to determine my ability to pay (presumably so they could determine what level of care to give me).

I would probably put both "individual pay" and "fully socialized" above our current system, or maybe a mixture, but one where there's true competition instead of the mess we have now.

I believe you're confused about how insurance companies affect health costs, there. When you look at a health bill, it does appear that the insurance company is keeping rates low by refusing to pay part of the billed amount, but what allowed those billed amounts to skyrocket in the first place? At one point, most people in this country could afford a doctor (who would make a house call) when they needed it. Then insurance plans came around and became widespread, and because some company was obligated to pay for the health care instead of the patient, prices shot upwards. Also, people began seeing the doctor for more trivial issues, because they "didn't have to pay for it," it was all "covered by insurance." This has, over time, lead us to the present time, where we have some of the most expensive health care in the world. An overnight hospital stay for dehydration in Mexico cost me $274, complete with IV fluids, anti-nausea/anti-vomiting drugs, my own private room with air conditioning, TV, and attached bathroom/shower, and breakfast. In the US, you could probably expect to add a couple 0's to that number, and I almost certainly would've been in a shared room, without the ability to control the temperature to my liking, with a bathroom further down the hall than I could walk on my own. In Mexico, I had to pay cash when I left. Here in the US, I would have paid more in deductible.

HUGE profit cushions? What airlines are you looking at? Airlines have historically struggled with being profitable at all. They typically operate on razor-thin margins, and some of the more creative have just in the last few years become profitable on an ongoing basis. There's a lot of money moving around in the airline industry, but a surprisingly small amount of it is profit.

I believe the airlines should charge not based on the weight of the passenger, but based on the weight of the passenger and all luggage/carry-on. So, tickets would be priced as "$xx.xx + $y.yy * [unit of weight]." A person might weigh 80 lbs but carry 100 lbs of luggage/carry-on, so they would be charged the base rate for a seat plus 180 * price/lb.

This is no different (and no more discriminatory) than driving; cars, like airplanes, use more fuel when they're weighed down more heavily. The fuel station isn't discriminating when they dispense more fuel to fill the tank of the car carrying a lardo, and the car isn't discriminating when it burns more fuel, it's simply obeying the laws of physics. Same with FedEx or UPS when they charge more for a 100-lb package than for a 5-lb package.

So, stop the ridiculous checked-bag fees, let people check whatever they want to free up the overhead storage for actual carry-on luggage, and charge for everything (passenger+bags) at a flat per-pound (or per-kilo) rate. Simple, effective, and non-discriminatory.

And my Civic coupe (gas) was $13k after all taxes and licensing were paid, and for my style of driving (>90% highway, most trips 40+ miles) I get nearly equivalent fuel mileage (35-42mpg). On top of that, it's WAY more fun than driving a Prius, I can work on it myself, and it'll probably go at least 400k miles before I decide to replace it, and though I may have to replace the battery a couple times, I'll never have to replace the entire battery pack.

So yeah, EVs cost significantly more than gas cars.

Comment Tech Skills aren't important for them. (Score 1) 302

Teach them that for many people, tech skills are pointless. They don't need "tech skills" to be successful in life, they need people skills, writing skills, basic math skills, troubleshooting skills, thinking skills. If these kids aren't excited about tech, team them things that DO excite them, like welding, or cooking, or auto repair, or carpentry, or plumbing, or any of a host of other things useful in real life. Not everyone needs "tech skills" to be successful.
