U.S. Senator: All Cops Should Wear Cameras

Agripa Enumerated Powers (611 comments)

Because cops wearing or not wearing cameras are in or affect the interstate commerce in cop cameras and cop camera accessories.

FBI Investigates 'Sophisticated' Cyber Attack On JP Morgan, 4 More US Banks

Agripa Re:Honest question from a non-USian (98 comments)

The FBI also uses the excuse that the crime *might* have crossed a state line or border. I expect at some time in the future they will add, "The crime may have affected interstate commerce or involved items or materials that may have crossed a state line."

Ask Slashdot: What Old Technology Can't You Give Up?

Agripa Old Test Equipment (610 comments)

Analog oscilloscopes would be at the top of my list but some other old test equipment could qualify as well.

MIPS Tempts Hackers With Raspbery Pi-like Dev Board

Agripa Re:no price? (88 comments)

What makes the Pi attractive is relative openness.

Isn't the BeagleBone Black even more open?

Reformatting a Machine 125 Million Miles Away

Agripa Re:Alternative Title (149 comments)

I would imagine that the system probably boots itself off of a ROM chip that has a routine for receiving data from Earth and storing it in RAM and then flashing that data onto the flash chip.

I wonder if the ROM would actually be a floating gate ROM instead of mask ROM or fuse based PROM in which case it would be more like EPROM or NOR Flash.

Does anybody even make mask ROM or fuse based PROM any more?

Reformatting a Machine 125 Million Miles Away

Agripa Re:ECC? (149 comments)

ECC use is standard with all flash storage. Flash is so unreliable that it can't be used without it, and it has nothing to do with the hard radiation environment on Mars.

NOR Flash does not normally use ECC and has reliability closer to that of EEPROM than NAND Flash.

Reformatting a Machine 125 Million Miles Away

Agripa Re:ECC? (149 comments)

The long duration radiation performance of flash memory (particularly back in 2000, when these things were being designed) was/is not particularly well understood.

Flash is another form of floating gate memory. Wouldn't the known long duration performance of EPROM and EEPROM apply?

Researchers Find Security Flaws In Backscatter X-ray Scanners

Agripa Re:This is ridiculous. (146 comments)

That strategy ceased to be effective at 9:03AM on 9/11/2001 over a field in Shanksville, PA. And you know who figured that out? Ordinary Americans, doing the security calculus themselves, where the government had completely failed to protect them, despite having many opportunities to do so.

And not only did the government fail to protect them and others, it did so while enforcing policies to prevent them from protecting themselves and others.

I think they got the government they deserve and continue to do so.

Researchers Find Security Flaws In Backscatter X-ray Scanners

Agripa Re:This is ridiculous. (146 comments)

Praising the actions of citizens acting as a traditional militia goes against the whole idea of them being forced to pay for their own subjugation. That is especially the case since those citizens acting as a militia were the only thing that worked to stop any of the four planes despite having been disarmed for their own good.

Is Storage Necessary For Renewable Energy?

Agripa Re:Expert?? (442 comments)

There is no such thing as negative energy price, unless you're retarded? Why would you pay someone to take your excess energy, when you can just dump it into the atmosphere through a resistor heating element? They are not that expensive, even if you have to finance one. Of course you might be benevolent and give it away for free, or even exert some effort out of love to they neighbor, and pay some for him to take it, but in a selfish capitalist view you can get rid of energy very easily, it's not like trash that is costly to get rid of.

Because of political rents.

If wind production is subsidized, then I may make money by paying someone to take electricity and power a giant electric heater with it. Even if I lost money by doing this, I might loose less money than if I did not sell the power at all. That may sound ridiculous but it happened not long ago in Texas because of wind power subsidies.

Is Storage Necessary For Renewable Energy?

Agripa Re:Expert?? (442 comments)

I once worked for an engineer who previously had a physicist working for him. The physicist couldn't understand why a couple of 6-volt lantern batteries in series wouldn't start his car - after all, they were putting out 12 volts.

An explanation geared for a physicist would have helped. "Imagine a spherical frictionless 12 volt potential source in free space with a 1 ohm resistor in series with it ..."

NVIDIAs 64-bit Tegra K1: The Ghost of Transmeta Rides Again, Out of Order

Agripa Re:special 128MB buffer of main memory? (125 comments)

In fact, it's fairly difficult to make RAM to decimal prefixes.

You'll have to pry my 2.147483648 Gb DRAMs from my cold, dead hands!

Idiot Leaves Driver's Seat In Self-Driving Infiniti, On the Highway

Idiot Leaves Driver's Seat In Self-Driving Infiniti, On the Highway

Agripa Re:Submission with a spelling error, say it isn't (406 comments)

Driverless cars will probably be mandatory in the future, and my guess is that the insurance will become so prohibitively high, that you'll find it much cheaper to buy an automated car.

Manual control of a powered vehicle will be an organ bank crime. Obscure?

Microsoft Tip Leads To Child Porn Arrest In Pennsylvania

Agripa Re:Really? (353 comments)

You can argue that the justice system might have an axe to grind against pedo's, and you're probably right, but they're still afforded due process.

But if this is not a search for purposes of the 4th Amendment, then the NSA or FBI or whoever can just provide a list of things for service providers to search for in general. Why limit it to child pornography?

And isn't that one of the current proposals to make current government searches legal in light of Snowden's leaks?

Microsoft Tip Leads To Child Porn Arrest In Pennsylvania

Agripa Re:Which company is next in line? (353 comments)

It certainly covers "We search your files based on a list of unlawful content given to use by the government."

I am sure there is something in their EULA which states that you surrender your 4th Amendment rights so it is all good.

40% Of People On Terror Watch List Have No Terrorist Ties

Agripa Re:High success rate or lots of unknowns? (256 comments)

If the people are dangerous and they find out they can't fly (which could really only be because they were on the No Fly list) then wouldn't that make them more likely to do something.

No, because they know that if they do something, they will be put on the No Fly list twice.

Hack an Oscilloscope, Get a DMCA Take-Down Notice From Tektronix

Agripa Re:Analog (273 comments)

For an older analog oscilloscope calibration is not difficult but for one that stores the calibration data digitally, calibration can be a problem.

Changing aluminum electrolytic capacitors is just another maintenance task for a test instrument old enough to need it.

Hack an Oscilloscope, Get a DMCA Take-Down Notice From Tektronix

Agripa Re:Analog (273 comments)

You don't need a recent Tektronix for that. As a matter of fact, I have a Tek 547 with a full suite of plug-ins. Does everything I need, and will probably continue to do so even after I'm dead. The scope's already half a century old, the original owner died 20 years ago.

A Tektronix 547 does more than most need and some things modern DSOs cannot like alternate sweep. My solution for that was to buy two of the same DSO.

I don't design and build my own brushless motor controller for example. What the hell for?

Oddly enough, Tektronix did design and build their own brushless motor controllers for maybe 2 decades.
