I've got a novel by John Brunner written in 1982 called The Crucible of Time (), which documents a (very non-human) species through its scientific awakening. Throughout the book they're discovering that their planet is getting closer to a cloud of debris dense enough to massively devastate the surface, possibly shatter the planet. In the end they manage to build enough arks to save the species. The foreward reads:

"It is becoming more and more widely accepted that the Ice Ages coincide with the passage of the Solar System through the spiral arms of our galaxy. ..."

Actually DVDs contain on anywhere from 4GiB to 9+GiB of mainline video... The whole reason for dual-layer discs was to get around the limitations imposed by the ~4.5GiB max of a single layer. The "base" read rate of a DVD (1x) is 1.32MiB/sec, which puts a 2-hour movie at peak bandwidth (hopefully because they actually maximized video quality rather than just being lazy with the encode) at 9.5GiB, just under the absolute max. Account for menus, special features, and average encoding levels, let's go with 6GiB.

OTOH, 2mph is rather low, with one source (http://answers.yahoo.com/question/index?qid=1005112200029) claiming studies put the average healthy male at 3.4mph. I'd also estimate there to be maybe a 50% functional walking time (eating, blisters, etc.).

And as others pointed out, on a serial line there are actually *10* transmitted symbols in a byte because of the start and stop framing. 11 or 12 if you add a parity bit and double-stop, but let's stick with 10.

"Furthest" redbox would likely be something like from Portland Maine to Los Angeles for example, which google puts at about 3100 miles.

3100mi / 3.4mph = ~911.75hr / 50% *roundtrip = 3647hrs
6GiB * 10bits/byte = 6442450944 symbols
6442450944 sym / 3647hrs = 490.69 baud

If one were to drive, as per Google it'd take ~46hrs with traffic, and if you trade off drivers. For that roundtrip I get about 19452 baud. Let's say 19.2Kbaud to leave time for chinese fire drills.

Agreed, I'm just pointing out that the "capital" absolutely exists on this planet, if enough of it is concentrated in just 25 people to achieve the task. Not saying they would personally, but debunking the implication that "it can't be done, it's too expensive".

I just totaled up the net "worth" of the top 25 people on Forbes 2013 billionaires list, and I got $839.8 billion. Not quite sure how $828.11bn is out of reach if certain people were sufficiently motivated, when it only takes the top 25. Now, if we were talking about something that cost $10 trillion or so, then I might consider it functionally out of reach, as that probably surpasses the net worth of the top several thousand.

Nope, there are two of you. You should start a (the?) local chapter.

Bias? Sounds to me like he hit the nail on the head: she supports the crap the NSA is pulling, and is up for re-election. The correct answer is to *not* re-elect here. It absolutely has everything to do with elections.

Not sure you quite get the concept of underflow.... If it's a 64-bit field in cents and he had $1, an unsigned subtract of $2 would result in a balance of $92,233,720,368,547,757.08 (give or take a few cents).

I honestly think there's a significant aspect to the move to "ban" Feds that people are overlooking: safety and liability. DEFCON gets a bit rowdy at the best of time, in the current climate re: PRISM, Snowden, etc. I seriously think the move will save a few bloody noses, possibly broken bones, and likely lawsuits and criminal charges stemming from the same. The conference also shields itself from the associated liability. A lot of people, especially in the hacker/DEFCON community, are *seriously* pissed at the US gov't right now, and that's gonna cause a lot more friction than normal.

Ohm's law is completely irrelevant to this situation *in the form you describe*. "Burning a hole through the board" would be possible and a simple function of Ohm's law only if they were using a linear regulator to generate the Vcore. But VRM's have been switching DC/DC converters since the 486 days. They achieve a voltage conversion by switching the incoming voltage on and off *very fast*, which results in an output voltage that's a function of the input voltage and the duty cycle of the on/off switching. An inductor (current-smoothing) and capacitor (voltage smoothing) give a nice clean DC voltage.

The differences between on-motherboard VRMs and this new in-package (it's technically a separate chip...) are significant. First off, physically moving it closer means that you're not sending 100+ Amps of current over the 3-4 centimeters of generally very thin copper traces on the PCB, they're sent millimeters through die-bond wires, or even through a solid substrate (no idea what Intel does at that level). There's your Ohm's law coming into play at that level, but the power losses there are relatively minimal since you're talking maybe a few tenths of an ohm. Die-bond wires are going to drop that to 10's of milli-ohms probably, so nothing major but still a positive effect.

The main reason this will generate a lot less heat is because of the *frequency* of the switching. Because this on-board VRM is so much smaller, it can switch the input faster (shorter wires, less parasitic capacitance, less ringing, etc.). This in turn means smaller value components required, e.g. the switch from the monster inductors seen on the motherboard (at maybe 1-2MHz switching) in the slide to the tiny chip-scale inductors on the FIVR (at 10's or 100's of MHz). The end result of all of this is that switching losses get significantly smaller. It's those losses that create heat local to the regulator. If they can for example go from an 80% efficient VRM to an 90% efficient FIVR for a 100W CPU load, they reduce the switching losses from 25W to 11.1W.

Given how much "revenue" city police get from traffic violations, I'd think they'd be all for this. Get the population that's fed up with jackass drivers to buy and install cameras that do the cops' job for them in court, bringing in additional fines without adding more traffic cops.

I'd call that a win for everybody except the jackass drivers.

The scenario I'm more interested in is having a camera running at all times that catch the various idiot drivers all over the place. Hit a button and the last 5 minutes and anything until the next press are permanently stored. Then send the file to the traffic cops.

The challenge is making the video admissible in court with sufficient weight to be enough to actually convict somebody of the traffic violation they're on tape performing. Currently "we" consider a cops' word as overwhelming evidence in such a case, with police dashboard cameras being a "bonus".

If there's some way to ensure that *I* don't tamper with the recording at a level that the courts would trust, I'd install one in a heartbeat.

I'd tend to say that when the "confiscation" has no legal basis whatsoever, we can very accurately call it "stolen".

It's faaaaar worse than that. One of our borehole geophones came back from a job at Hanford with the 1/2" thick aluminium tube so eaten away that it had to be replaced. That would be 100's of meters down a hole (I think they had a 500m cable...).
