Comment Re:Ron Wyden Edward Snowden (Score 1) 107

5 seconds later, he'd be arrested for revealing classified information. Then the American people would vilify him as a traitor for letting the terrorists know how they're being watched, and he'd be put on trial for treason. In the end, it would make no difference. Nothing will until the majority of the people actually care and desire to not be spied on.

That would be quite a trick:

But an arrest record seems to be a big deal in the US and is tracked? Unlike in many other common law countries where an arrest, even with a charge, means *nothing* whatsoever if you are not convicted or charges are dropped, and it cannot be used against you in any way.

Yes, arrest records are tracked and a job application may specifically ask about arrests.

Or, hell, transfer over my wifi network. Since my phone supports USB3 (Note 3) I actually use that, but my girlfriend's phone doesn't, and transferring over a low-interference 5ghz wireless N network seems roughly as fast as USB2, without having to mess with plugs that wear out.

I will be looking for wireless data transfer in the next camera I purchase just for this reason. Right now I can either wear out the mini-USB connector or wear out the SD card slot. It is too bad that optical like IRDA never become commonly available.

Comment Re:Not particularly useful, unfortunately (Score 1) 204

True, but SSD manufacturers say the drive should hold its data for at least 10 years after the drive has reached its recommended lifetime (these drives were well past that).

That sounds like a specification they got from a high density Flash datasheet which I saw recently; it was 10 years typical with no guarantied minimum. My own tests show that high density Flash has a retention of months. I assume SSDs can get away with that because they can perform background scrubbing while powered but the USB Flash drives that I have tested do not and they forget their contents before a year is up whether powered or not if they are not actively used.

Based on old datasheets involving floating gate memory which did list minimum retention times of 20+ years, I have the feeling that the manufacturers do not specify minimum retention because a low duration of months would look bad.

And things like Solar, Wind, and Wave wave aren't usable as baseline "brown" power. Because their generation sources are not stable and dependable. BUT, they can be used, alongside existing hydro and geothermal to offset demand spikes.

Since utilities are usually required by law to buy solar or renewable production before other sources including nuclear, the renewable sources which cannot be used for base-load also make the sources which can be used for base-load less economical because they have to operate at less than full capacity. This especially helps make nuclear power uneconomical. Continue with this trend and no baseline production will be economical.

If you replaced the boot flash and SD flash with mask-programmed devices, it'd certainly boot a 100 years from now. No doubt about it.

Lots of mask ROMs produced in the 70s started failing 30 years later. Maybe this was just a problem with Mostek but I would not bet on it over a longer period of time.

Tantalum capacitors are not exactly everlasting either when unpowered for long periods of time. Maybe newer ones are better but older ones seem to suffer from defect growth over time. The defects are cleared harmlessly while the capacitor is used but if allowed to grow too large cause failure when power is applied. The solution I have used to combat this is voltage derating.

Some people say that SD cards degrade after a few years, even without writing to them.

High density Flash memory degrades within months to years depending on the density unless scrubbed or refreshed. My own tests revealed that the 4GB USB Flash drives I have been using lost their contents within about a year whether powered or not. I assume SSDs scrub themselves when powered but USB drives and SD cards appear not to.

Naturally retention time of high density Flash is not generally specified.

Comment Re: ECC Memory (Score 1) 180

can you think of a way to do those tests with less cost?

The problem with the software only test is that it does not verify the operating margin in timing, voltage, and temperature. If the motherboard supports it, then raising the memory operating frequency by say 10% and lowering the DRAM operating voltage by say 10% and *then* running the software only test like memtest86 or maybe the Prime95 stress test should work to detect marginal DRAM.
