    The interesting part about the federal law is that it applies to unlicensed carry whether legal in the state or not.

    Routing only requires the IP header. Nobody except the intended destination address needs to parse anything else so everything else including the UDP or TCP or whatever protocol header should be off limits. I would apply this to law enforcement as well; everything not in the IP header is content.

    treaties override the US constitution as per precedent

    Treaties do not override and cannot amend the Constitution and they may be nullified by statute. What they do allow is limited power to a federal government outside of its enumerated powers.

    A burst mode or hysteretic converter can have very low (in the microamp range) quiescent current draw. At low or no output current, they spend most of their time shut down with only the comparator and reference active.

    The TI-30 and similar calculators used a 9 volt battery but had rechargeable battery modules which could be used as well that operated like this. Inside was a NiCd battery and boost converter which always ran producing the 9 volts that the calculator expected. Operating life was good even though the boost converter never shut off. Today we could do much better.

    "The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."

    The remedy for violations of the 4th Amendment is exclusion of evidence but this does cannot apply unless you have a trial. If they did charge you, then parallel construction would prevent the 4th Amendment violation from being revealed.

  8. Re:But since nothing is CPU bound on Intel Releases Broadwell Desktop CPUs: Core i7-5775C and i5-5675C · · Score: 1

    The demand for using unbuffered memory places limits on the number of DIMMs which each memory channel can support and each memory channel adds to the cost of the processor and motherboard. This limits DDR3 and DDR4 to two DIMMs per channel unless the memory clock frequency is lowered.

    Server processors and motherboards often support buffered memory so more DIMMs per channel but there is not enough demand to support this on desktops in the face of market segmentation.

    Does ALL that stuff die? Or is this - as I am going to go out on a limb here and guess is the case - just reshuffling the status quo a bit to make it appear that "something is being done", without reeling back the majority of this surveillance state that we've seen come to fruition?

    The court already ruled that section 215 does not cover what the NSA is doing so I assume they have some other secret justification which does not rely on section 215 or any part of the current law which is due to expire. They could always fall back to Article 2 powers.

    The acoustics are never going to be perfect you have to get used to it.

    It is not a matter of perfect. It is a matter of having way too many noisy distractions; you might as well have a loud phone ringing at random times on the desk beside you when you are not hearing one side of a conversation.

    People are simply stuck on terms like "Mebibyte" because they either don't want to accept the fact that mega is an SI prefix or because they don't like how the IEC units sound. Get over it [wikipedia.org].

    Maybe one sector equals a power of two, but the total number of sectors can be anything that the physical disk holds.

    It cannot be anything because the interface uses power of 2 addressing for the sectors. Does it make more sense to say that the current maximum size for a storage device using LBA48 is 128 PiB or 144.11518807586 PB?

  19. Re:Mebibyte is an idiotic term on Crowdfunded, Solar-powered Spacecraft Goes Silent · · Score: 1

    Makes perfect sense. RAM is addressed with a N address lines, giving access to 2^N cells, so base 2 makes sense. For everything else, base 10 makes more sense, especially when you're talking about speeds.

    Hard drive sector sizes are powers of 2 (with exceptions which are irrelevant here) and they use power of 2 addressing for their interfaces (with some interesting exceptions) yet they switched to measuring capacity using base 10. I remember when they changed and agree with the poster; it was for marketing reasons. Capacity measured using base-10 seems larger than capacity measured using base-2.

  20. Re:Seriously? on Crowdfunded, Solar-powered Spacecraft Goes Silent · · Score: 1

    Think of it like running win32 on a 64-bit chip with 8GB of RAM. It's nice having 8GB of RAM but Windws can't actually address it - it's a 32-bit kernel which means it can only address 4GB.

    This is not the best example since win32 including Windows XP before service pack 2 can address more than 4GB of RAM through PAE. Individual programs are limited to 32 bits of addressing (and from 2GB to 3GB of virtual address space) but multiple programs can be running with a total address space considerably larger than 32 bits will support.

    If the defense can bring in outside information to lower the sentence why can't the prosecution to increase the sentence?

    By doing this the judge and prosecution are effectively sentencing him for crimes which Ulbricht was not charged with and the jury did not find a verdict for. I understand that until recently that sentences could be based on the charges rather than the convictions so I assume this is the workaround for that. This encouraged prosecutors to overcharge simple to generate harsher sentences but now the prosecutors do not even need to do that.

  23. Re:lots of copper? on How Tesla Batteries Will Force Home Wiring To Go Low Voltage · · Score: 1

    2:1 input voltage ranges are common but 4:1 input voltage ranges require compromises in converter design; for a given cost they are less efficient or for a given efficiency they cost more.

  24. Re:Why Low Voltage DC? on How Tesla Batteries Will Force Home Wiring To Go Low Voltage · · Score: 1

    Most switching power supplies which lack active power factor correction stages expect 120 or 240 volts AC and operate on 340 volts DC internally. They will run fine on 340 volts DC but 120 volts DC would represent a moderate undervoltage condition which could result in catastrophic failure do to their negative resistance input characteristic unless the power supply was designed to operate down to 84 volts AC.

    A switching power supply with active power factor correction might do better but I would not rely on it.

  25. Re:Save in conversion, pay for copper on How Tesla Batteries Will Force Home Wiring To Go Low Voltage · · Score: 1

    Seems to me a better solution would be to research ways to convert from DC to AC more efficiently. Currently there's up to a 40% power loss. That's just begging for some research money....

    Two stage AC to DC followed by DC to AC power conversion in the kilowatt range and larger is already routinely better than 90% efficiency so the point of diminishing returns has already been reached. The efficiency numbers given in the article are wrong except in the case of low power or low quality equipment.

    Higher efficiency comes at the expense of better and larger parts which adds to the cost and increases the size and weight.
