Comment This could be an interesting precedent. (Score 1) 588

I wonder what would happen if his cousin, who's sensitive to electronic signals emitted by active, electrically unterminated gigabit ethernet cables decides to attend the same school. Or his sister, who's has epileptic photosensitivity at 60hz Or his younger brother who may attend next year but is allergic to asphalt, formaldehyde, pheremones, and can't metabolize sugar.

Read again - more temperature means less time. So if there's no lower limit, SSD without power will be best stored at 0 Kelvin

No I read the article. It's related to electron mobility at the time the data is written. If you heat up the SSD after it's turned off, electron mobility increases and you'll get more leakage. But if you wrote data when it was hot, you have a better signal to noise ratio.

Comment Eureka! (Score 0) 184

So.. It's better to cook my SSD so that it can retain longer at 30 degrees poweroff? Guess i'll mount it to my cpu's heatpipe next time instead of the drive bay with the fans and good airflow, screw common sense! I guess those thermal pads were actually to help keep our nand toasty instead of cooling them after all!

Comment What does this bring to Swatting? (Score 2) 79

Lets put aside the ethics and legalities of what the FBI is proposing to do. Now it seems like this enables tricksters to engage in much larger scale abuse. Trick the FBI to hack Foreign government networks, infrastructure and companies (and get caught, since they are presumably not currently as good at it as the NSA). After all, they no longer need to do their due dilligence before cracking into aunt Bettie's IoT connected iron lung if her state owned ISP issued her an insecure router. Lets use an exploit to hardware reset that microcontroller, nothing could possibly go wrong, could it?

It seems pretty straightforward, they carefully control the amount of oxygen at the bottom of the machine relative to the cross sectional area of the portion being printed so that the rate of polymerisation matches the the volume of plastic being drawn out of the unit. In a normal machine, after you cure a portion, you give it time to cure because throwing more energy at the resin will cause blooming and lack of resolution. This limits the amount cured chemically. Think of it as analagous to magnetic optical recording. Increasing your write current on a normal wite head increases the area written to, but the laser limits the area affected.

I have an internal pc network, and separate wired networks for media, appliances. In some cases just to prevent them from auto updating to newer firmware that introduces advertising. Just as there is a guest network to keep guests and their kids out of DLNA shares and prevent torrenting. Then as any responsible consumer, the htpc is on a green power strip triggered by the light switch on an occupancy sensor since i can at least be in the living room before the components start sucking the 30 watts of standby power. If someone gets as far as my living room, i either dont care if they want to watch tv, or i am in no position to refuse. These components are designed to be idiot proof and authentication free. I'm not concerned that my infrared remote receivers are not paired, nor do i lose sleep at night that my neighbor could modify a universal remote and prank my tv through the bay windows either. I do concern myself that my locks weren't bump proof or that there wasn't a fire extinguisher near the kitchen, and that there are some vulnerabilities in my Nest.

Comment Mechanical notch filter? (Score 3, Interesting) 114

seems like it only affects sound or wave functions in a specific frequency as determined by the speed of the air movement or electron migration rates or whatnot. Might not be very effective for general sound insulation unless it's fixed frequency, o (or else you'd hear the generated harmonics). Not too different than active noise cancellation.

Comment A bit of the old and new but NAND? (Score 1) 25

This sounds like MO recording with sound waves instead of a laser. I don't see how this works with NAND flash though. Even if you can increase the number of voltage levels stored on a cell after heating, wouldn't each cell need to be exposed in order for it to be targeted by the ultrasonics?

Comment Only way this will work is (Score 1) 307

If someone developed a botnet of proxying servers. As long as users voluntarily install tools that provide proxying services, the responsibility for its use falls on that user. However, if the proxying were the result of an infection by a recognized virus, then there's an argument that the user had no intention or idea that they were proxying material. Not that I'm advocating such an idea, but I believe that if proxied torrents become standard, someone will make such a virus.
