That's an interesting thought. By hypothesis, these reboots are covering up a resource-starvation/exhaustion situation. Fine-tuning the limits and timeouts presumably heads this off. Add more memory could also prolong the time between failures (but is likely hard). Since many of these are little Linux systems, does anyone have any experience getting some kind of kernel stats out of them?
My Linksys router is on a UPS, and will sometimes go for three or more months without a reboot. My DSL modem, also on a separate UPS, is a bit more likely to lose its PPPoE connection and require a reboot, every month or so. Whether that's my Thompson modem or the telco DSLAM is an open question. I know my power is quite dirty, hence the UPSes.
because they pursue it themselves: see this or Google "economic espionage" and France. And this 1992 item about Air France's involvement in bugging first class seats.
I recall being told never to trust the shredders in French hotel rooms: they may have a scanner. Can't find that online, though.
Beware - melting zinc produces vapour that is at least mildly hazardous.
BTW, Canada reduced the metal weight in our one cent coin, it's a thin coin with a raised edge. And instead of round, it was for a while polygonal - twelve sides, I think (The 1983 one I have here is.). I have here a 1982 US cent and a 2006 Canadian one. The Canadian coin is perceptibily lighter. Of course, that could be copper vs. zinc, too.
I sorted a small batch, and using an old analog postal scale, here's what I found:
Seven current, round Canadian pennies made one-half ounce.
Six older 1982-1994 polygonal Canadian pennies made one-half ounce.
Five old 1961-1976 round cents made one-half ounce.
Ah - the legal standard says there are three current compositions:
... bronze (copper, tin and zinc); 2.5 grams
CPZ (copper plated zinc); 2.25 grams
CPS (copper plated steel); 2.35 grams
At 154/lb the US cent is nearly three grams - 30% more metal. Seems to match the older Canadian coins.
A magnet test found one each 2004 and 2006 CPS cent - my other 2004 and 2006 were either bronze or CPZ. I think I'm going to convince someone I have a "special magnet" that picks up copper:-)
My house came with a very pretty finished basement. The 70 amp subpanel that had been added for the basement was correctly connected through a piece of conduit. Looked great... until we needed to open it up. Turned out to be 12-gauge wire inside the conduit! Scary.
It turned out that the rest of the basement was pretty evil, too. Salvaged moldy timber, no vapour barrier - had to rip it all out at significant expense.
Traditionally North American property taxes have been computed on the "mil rate" - where the "mil" or "mill" or even "mille" is a "millidollar", or tenth of a cent. The lack of a mil coin has not particularly bothered anyone, although a half-cent coin apparently existed until 1857.
All "hard money" is just an accounting fiction anyway. As are paper money and credit.
Gresham, of course, observed that "bad money drives out good", or that where there are two currencies with the same face value and differing intrinsic values, the one with the high intrinsic value disappears (by hoarding or conversion.) Gresham's law is why you don't see many old silver coins in your change.
The rule in TFA is an attempt to avoid Gresham's law; it's left as an exercise to determine how large a profit on converting metals is needed to make the risk worthwhile. The orthodox economic prediction is either a shortage of small change or a reformulation.
The case of the circulating penny provides a counter-example - there's a cost to conversion, and the roughly 100% excess value isn't quite enough for most people to horde the coin.
as it relies only on being intractable. Throw enough (quantum) resources at it, and it is directly breakable. The fact that on average it takes CPU-centuries is irrelevant to "unbreakable".
What parent post said. I did read the bill. The dangerous part is subsection (f)(2) "Negligent Failure". Even through subsection (g) claims it creates no need to "seek facts", the existence of sanctions for "negligent failure" does imply a duty to surveil. The reality is that this bill would create a need for every ISP to buy serious insurance against violations; or shut down discussion forums entirely. Which would be the easy business decision?
Love the Orwellian title. As always, it's "for the children". CDA, redux.
If double negatives (as a strong negative) were good enough for Shakespeare, they're good enough for me. The notion that a double negative is a positive belongs to logic, not English.
It's like split infinitives. I tend to carelessly split my infinitives.
The jokes about DRM make this sub-thread just a little scary. We know that a variety of things were invented and then lost in the ancient world. There are chicken-and-egg problems all over the place - you can't teach the peasants better farming, cause they can't read or count very far. You need a reliable calendar - and that needs lots of observation, which means some agricultural surplus. And you can't teach the peasant's children because they are needed for subsistence agriculture. So you wind up with this long-term semi-stable semi-feudal system, that supports a few intellectual accomplishments. Which get lost regularly, because two bad crop years in a row can wipe you out.
Then suddenly, you get a break, and things take off for a long run of progress. In our case, it's been over a thousand years, longer than either Greece or arguably Rome. Dating modern society back to someplace around Charlemagne, anyway.
So, we got past that... but two bad legal years in a row could lock up all the information, and recreate the semi-feudal aristocracy, only with corporations instead of lords of the manor. Link favourite scary SF story here...

Anytime that the process concerns dominate making product, supporting product, doing business, making money, you're in the soup. Any process, methodology, tool, language, whatever can be used to make product. And any process, etc. can become an idolatrous religion. Except Linux, of course.
But the destructive potential (not pun intended) of a system designed to flash charge that much energy is amusing to contemplate. Add a couple of "good ol' boys" and a few beers, and watch from a safe distance. Low orbit, perhaps!
500 kWh in 9 minutes is 3333 kW
at 115 volts nominal, looks like 28985 amps!
Electrical code allows 20 amps in 12 gauge wire, 12 gauge is 3.3 mm**2 cross section, we need over 3300 mm**2 cross section - call it sqrt(1000) mm.
That charging cable's in the neigborhood of a foot in diameter! OR the voltage must be much, much higher.
So, sounds like you still need a "gas station", or rather "charging station", with a substantial infrastructure. Or, you put a duplicate capacitor in your garage and trickle charge it, then blast it over.
I don't know about you folks, but I'm not going to be connecting and disconnecting thousands of amps in my garage. Not twice!
The hack, of course, relies on what is possible, not what is usual... You get extra money by progamming the machine to believe it has $5 and no $20; you could program the machine to believe it had $100 when it actually had $20, but that would get reported fast!
Royal Bank of Canada used to do $5 and $20, which was fairly useful. Now it's almost all $20. Some Canadian banks give $50 and $20; a fifty is hard enough to break that I avoid these or select an amount such as $80.
Verily, fellow old fart. The Windows Scripting Host (WSH) makes javascript an attractive way to do quick little programming tasks, on a Windows box (shock, horror). And you can do serious things with it easily.

I have an outdoor-rated CF on my post lamp. I haven't noticed it not working in the cold, and we've been enduring -25 C or so lately.

So while ago, there was an agreed standard for web metadata, the Dublin Core Metadata Initiative aka ISO Standard 15836-2003. Very few people use it.

It seems a substantially unrealistic exercise; few North American interiors have exposed brick.

We've had continuously operating educational institutions about a thousand years - the oldest universities of Europe.

Code review is good. Date code is notoriously slippery... I've addressed the points raised.

I think that's what's going on - IBM has no economic case for fighting this battle for us, they are drawing a line in the sand.
