Though if you want good, it won't be cheap, just cheaper than good and fast. That and for certain values of "fast", there's not enough money in the world to make it happen, buggy shit is inevitable.
There's countless halfass buggy code embedded devices out there, and now more and more they are getting connected to the outside world. So we'll see more and more 'zombie attacks', or plant meltdowns or whatnot, I'm sure.
Maybe the MBAs will eventually figure out the importance of security, but not likely.
I like how euros (and most European currencies in general, IME) physically scale(d) with value, very handy even for a person with good vision.
Definitely disagree on the 1/2 bills though. Canada got rid of both years ago, and there's just too much bloody change. I need to get suspenders or something.
(we did finally kill the penny this year, though. thank god).
The newer beaglebone, the beaglebone 'black', is $45 everywhere. This is the best thing raspberry pi has done, I think... make beaglebones cheaper.
It's got: 1GHz arm of some sort, 512MB RAM, 2GB flash storage onboard, more through SD slot.

Well, they aren't on the shelf like normal 'OTC' stuff, yet they also don't require a prescription. The pharmacist typically logs the sale, to thwart people buying oodles of things.
Here's what wikipedia calls this in the US:
Restricted OTC Substances
An ill-defined third category of substances comprises those products having over-the-counter status from the FDA, while being simultaneously subject to other restrictions on sale. While these products are legally classified as OTC drugs, they are typically stored behind the counter and are sold only in stores that are registered with their state. Such items may be unavailable in convenience or grocery stores that stock other non-restricted OTC medications.
For example, many U.S. drugstores have moved products containing pseudoephedrine, an OTC product, into locations where customers must ask a pharmacist for them. A prescription is not required; the change has been made in an effort to reduce methamphetamine production. Since the passage of the Illinois Methamphetamine Precursor Control Act and the subsequent federal Combat Methamphetamine Epidemic Act of 2005, the purchase of pseudoephedrine in the United States is restricted. Sellers of pseudoephedrine must obtain and record the identity of the purchaser and enforce quantity restrictions. Some states may have more stringent requirements [... ]
Canada is same / similar (for weak codeine things, at least), there's a bit of an inquisition but you don't need a prescription.
I think it's still OTC, in Canada at least. but I thought the US as well.
You have to ask for it, andi It's always got tylenol mixed in as a denaturant. (i.e. if you drink a whole bottle, they would prefer you die instead of get high. solid logic).
Codeine is still the gold standard for cough suppression, so it seems unlikely that it's outright banned. Maybe Rx only in the US, though.
Bingo. I see this argument pretty frequently with any reaction-derived drug, take meth, for example. Oh it contains ammonia, lye, solvent, iodine, etc, which is why it is terrible and must be illegal.
But those things are only in it because of it's illegality, and backyard hack chemists. It's pretty disingenuous to imply that these contaminants are an essential part of the drugs.
Funny thing, I'd imagine desomorphine or meth from Novartis or Merck & Co. doesn't have these problems. Oddly their heroin is pure too, not black tar, and I imagine their cocaine isn't half cut.
Yeah, most anything that ends in R is good. Things ending in V should be illegal to sell as they do. (and others.. one of P or U, I forget which is worse)
Y5V for example. At 40% of rated voltage it is down to only 20% of it's nameplate capacitance. If the temperature is above 60C, it loses another 50% on top of it.
So a "16V 100uF" Y5V capacitor, running at 6.5V and 60C, is down to 10uF. What a joke.
ESR can be pretty important factor too, for say, switching power supplies. To move from a normal electrolytic to low ESR electrolytic seems to increase the price a few fold. Ceramic is low by nature, tantalum is quite lower than electro in general, but lower is more money again.
Then of course in tuned circuits, stability / tolerance / etc is one of the important factors, where you want little drift in capacitance. So something like low-drift ceramic, or silver mica, or film. For bulk caps smoothing a power rail, no one cares of course.
One spot where tantal really shines is cold weather. Electrolytics lose capacity a lot in freezing temperature, tantalum (and some ceramics for that matter) doesn't have this problem (as much, still loses some.).
There's other important things for other tasks that don't really concern me... dissipation factor and stuff like that in high power applications, etc
So.. more than three qualities, anyway, was the cause of my ramble.
Oh yes, tantalum is also much higher (capacitance) density (so smaller). But new ceramics are pretty close in some areas.
There's been a bunch of these over the years. To get the weapon to actually initiate fission, all the charges have to be fired with very precise timing, to compress the material into critical mass. If the charges go off accidentally, you don't get fission, rather it just blows the fissile material all over the place. What murrican tv likes to call a 'dirty bomb' i guess.
A B52 crashed and its bombs went off near Thule AFB in the late 60s (non fission, again). Greenland/Denmark had been lying to it's citizens that US planes were not carrying nuclear arms on their territory, but certainly they were. (this was a regular patrol, govn't said emergency / temporary / something). Seem to recall everything melted through the ice and recovery was a big trainwreck, they recovered maybe half of the fissile material... something like that, anyway.
They had a big deal about it uh.. maybe 20 years ago when it came to light that the flights were regular.
The TFA seems to imply the RAS has been wholly independent for 289 years, which is obviously not the case... It was founded by the tsar who I'd imagine had some sway.
That and oh... it lived through the soviet union, which certainly had control.
The Russians always used strontium 90. Slightly lower heat output and shorter (~30 vs ~90 yr) half life. Much cheaper.
Of course the reduced half life means power will drop off sooner, but I'd think thermocouple aging factors weigh more heavy anyway (for the first decade or two, at least). Maybe not?
So for long missions You'd want something else, I guess.
Ottawa is the capital. If you include the greater area and Gatineau (across the river), they have a population of around 1.2M, rounding out the top 5. (calgary is about a tie in population).
Yeah, 'accidental' civilian deaths, or deaths from 'necessary collateral damage' are so very noble and just.
In Serbia the US/NATO 'accidentally' bombed a farmers market, two hospitals, the Chinese embassy, civilian radio/TV stations, bridges on the wrong side of the country with civilians on them, etc. Also random factories that weren't military-related industry (eg. tobacco) - Interestingly the tobacco factory got bought by Phillip Morris a couple years later...
Chemical weapons are abhorrent, absolutely. But unless use is widespread, picking winners and causing more death and destruction isn't ideal, neither.
Slashdot Mirror
Lithium ion cells don't have rare earths in them, that I'm aware of.
NiMH does use them, though. Ain't seen a laptop or phone with NiMH cells in a long time...
Nah, it's the typical engineering trilemma... fast, good, cheap; pick two.

Obviously it should define '0' as a variable, and then set its value to that of uid...! :p

It's a bullshit line to make the feeble minded weep for the rich, and take pity on them. There's nothing else to understand about it.
No, that's all wrong. They need to make the screen sharper.
Then the reactors will be cooled with jellyfish puree. I'd imagine that would have a similar specific heat to water.

My Serbian friends have told me that a $50 microwave with the door taken off can destroy a $200k HARM.
Sounds like urban legend to me, but, pretty comical if true. You'd think Raytheon would be out deploying microwaves if it were the case.
DB-25 was suggested but not mandatory, AFAIK.
DE-9 variant was open, with off the shelf connectors, and became a de facto standard. It was done to be cheaper and smaller... not for vendor lock in.
(eventually TIA made it de jure, with TIA-547).
5V ain't gonna cut it without some sort of trans-dermal probes... Skin resistance is just too high for such a low voltage.
Yeah, most anything that ends in R is good. Things ending in V should be illegal to sell as they do. (and others.. one of P or U, I forget which is worse)

Same as there is no U in Rossiya, or no 'Greece' in Ellada. English has it's own name for some things, instead of direct transliteration.

Royal purple was very expensive, as you had to poke / squish thousands of snails to get enough purple snail snot to dye a coat.
We have better living through coal tar^W^Wchemistry now, though.

Eh? Teflon decomposes to nasty stuff like HF... not exactly benign.
It definitely gets below -40 here (not including windchill) on occasion. Not a very good time.
I guess the record here was -51 (-60F),
record windchill was -60 (-76F)
brrr
