### Water Bottle Fills Itself From the Air

Re:3L per square meter per hour @ 75 percent humid (173 comments)

Your math is off. I don't have a 710ml bottle handy, so I did a 12oz can.

Assuming 6.5cm * 12cm, ignoring the bottom and top surfaces, just the sides of the cylinder, I get 490 cm2, which is .049 m2.

3l * .049 = 0.147; 147ml/h. The can will be a 40% full in an hour, in 75% RH.

I assume the performance in drier conditions is much worse, though.

Although, once the liquid is in the container, it loses surface area? I didnt bother reading to find out whether the inside or outside or both count. math was assuming one side.. If it is the inside surface that does the work, the increasingly covered surface will give reduced efficiency as it approaches full...

### High-Voltage Fences For Zapping Would-Be Copper Thieves

Not sure what you're on about. Maybe you should look it up in oxford first.

Definition of electrocute
verb
injure or kill someone by electric shock: a man was electrocuted when he switched on the Christmas tree lights
execute (a convicted criminal) by means of the electric chair.

Origin:

late 19th century: from electro-, on the pattern of execute

### High-Voltage Fences For Zapping Would-Be Copper Thieves

I really hate when people say 'electrocute' when they mean 'shock'. Big difference.
You don't walk off being electrocuted, it's the end of the line.

Unless he's actually planning on having a lethal fence, which is fucked, not to mention a massive liability.

Re:OMFG Reagan was right? (861 comments)

Something tells me the Palestinians aren't using bleeding edge Russian or US ICBMs.
If the system was effective against that, you might have a point, however I doubt it would be.

I think there's only one way things end up if MAD is disturbed too much, maybe not right away, but sooner or later.

A better example would be if American Indians, subjugated and embargoed on their reservation, started rocket attacks on the US.

### The World's Oldest Original Digital Computer Springs Back Into Action At TNMOC

Re:828 flashing Dekatron valves (65 comments)

Tube logic was inefficient, and had reliability issues due to short life, but they were capable of high (MHz) switching speeds. Of course the size of things raises problems, and you have to run it a lot slower than any given gate could run, I suppose. Line driving issues, stray capacitance in the miles of wiring and whatnot, will kill your sharp edges and miss pulses.

Cold cathode, however, was slow as fuck. A couple kHz, maybe, for neon; somewhat faster for argon. Hydrogen was the fastest IIRC ( the small size must (de)ionize faster - must why they used it in high speed thyratrons for pulsed radar and whatnot also?), but still in the kHz range.

### The World's Oldest Original Digital Computer Springs Back Into Action At TNMOC

Re:Not a digital computer (65 comments)

However the Dekatron valves could be made in effective binary mode (9 anodes to 1 pin) so it could still be a binary computer.

That wasn't for binary, it was for allowing less complicated tubes if they were only going to be used as divide-by-10. Instead of drawing out all 10 cathodes, cathode 0 has it's own pin, and 1-9 are on a common pin... as you only need to measure / know when cathode 0 goes high again (signifying 10 pulses have occurred).

If they only needed binary it would be a flip flop instead (either tube, for 'high' speed, sometimes glow lamps in slower things)

but yeah, absolutely digital.

Police were giving me a hard time in Balkans, taking photos of pretty benign stuff there. I'd imagine Russia is worse yet, for things like that. Old mentality, something.

### With NCLB Waiver, Virginia Sorts Kids' Scores By Race

Re:Embarassing day for whites (622 comments)

You forgot imperial fluid ounce.

Canada is kind of silly. We get:
1.14L bottles of whiskey (UK quart, 40 oz),
1.18L bottles of 'malt liquor' (US 40oz).
Litres of milk, gas, juice, etc. (but juice also comes in US pints).
Beer comes in 341ml bottles (12 UK fl. oz.)
Beer also comes in 355ml cans (12 US fl oz.)
Cola comes in 12 or 20 US oz, and then litre, 2L.

Odd thing with cola - following metrication, for a time we had 500mL cola bottles, glass. Then they went to plastic, "bonus 100ml NOW 600ml!!" bottles. Years later it was revised to 591ml (20 US oz.) - Thing is, it had been a 20oz bottle since they moved to the "bonus", many years before... and they were just fudging the number.

Some of it is really weird. There seems to be no hard metric (one litre, say) hard liquor, even european liquor. They give us UK quarts, even for things like jagermeister... Which comes in 1L bottles in Germany. Why?

We really got robbed in some areas. We used to get things in Imp. gallons (4.55L), got metricated, which moved to hard metric - 4L, and with lack of regulation, i suppose, and less domestic production... everything seems to come in 3.79L, American gallons.

Of course the price didn't change, so we just got robbed 20% volume is all, and made packaging cheaper for Americans. (or Chinese, selling to both markets).

Come to think of it.. the American gallon invasion seems to fit roughly with the timeline of NAFTA.

### Secession Petitions Flood White House Website

Canada is rather an anomaly in this respect, FPTP generally leads to only two viable parties.

But, regardless, there have still only been two parties (if you count the different iterations of the conservative party as the same) that have ever had power at the federal level in Canada, so it still holds true.

The only time a third party gets second place is when Quebec feels like it. (Bloc in 1993, which was really a party made of defections of the first two anyway, and just recently the NDP, which is a genuine third party).

Quick look at how badly FPTP hurts small parties:
(% vote) (% seats)
39.62% 53.90% (con)
30.63% 33.44% (ndp)
18.91% 11.04% (lib)
6.04% 1.30% (bloc)
3.91% 0.32% (grn)

See how brutally that favours the top two parties? 70% of the vote gets 87% of the seats.

What's even worse is that the first place contender often receives an absolute majority with less than a majority of voters supporting it, as in this case. FPTP causes this, and it's inherently undemocratic as far as I'm concerned.

### Canada's Supreme Court Tosses Viagra Patent For Vagueness

If the patent isn't understandable by someone proficient in the field, it is invalid. I'd imagine the Supreme court had called up experts.

The radio said - patent described several chemical structures, but neglected part of the process or which one was the final patented product, something along these lines. Which would be unrelated to the hard to understand part.
