does it suck that the US generally uses different things (units, digital telecom carriers, etc.) than the rest of the world? yes.
does it suck that much? no.
both SI and Imperial units are pegged to arbitrary things. In the case of Imperial units it was some king's foot. In the case of SI it is the distance light travels in some amount of time. whatever.
any system of measurement we develop is going to be arbitrary, and will probably break down at both extremes as we discover more about the nature of the universe.
no, depreciation works differently than that. If a good (like most technology) has a steep depreciation curve, that can come from parts being expensive and hard to come by. (it can come from other factors too.) Thus no one will want to buy a used item precisely because it's expensive to repair.
i'm sure that solar panels aren't the only cost involved in a project to take a house off the grid. I'm pretty sure batteries or another energy storage technique are involved. Few batteries, much less large capacity batteries will last longer than 10 years. Further, battery longevity is presented by manufacturers under the most ideal conditions. I would expect to be replacing batteries within 5 years because of deep evening-overnight discharge.
but even if they were, i'm less than sanguine about reality reflecting the 25 year claims. Additionally, there is no consideration given to mechanical frailty. i.e. how well can a solar panel take a baseball from the neighbor's kids? large hailstones?
depreciation value measures what you would be able to sell your asset for because that is the best source of available data.
however the measurement sees more use than just its nominal one which you tunneled down on to criticize the GP for using.
instead, it is common to also use depreciation value and horizon (timeframe) to estimate the life of the capital investment.
the trollish contradiction to you would have been along the lines of, "what, do you expect his solar system to last forever without repair or part obsolescence?"
rather than troll you as you've done to the GP (naively or willfully), i've pointed out that equipment does age and need further investment, both incrementally for repairs and in bursts for system replacement. i've also pointed out that the GP was correct in using depreciation as a rough measure of how much to expect to pay to keep the system happy over time.
to use a less green emotionally charged example, i spend $10,000 to replace my business' roof. My roof has a warranty, but more importantly i can look up the depreciation of roofing in actuarial tables because i also have machinery, computers, and a whole slew of disparate things to track the longevity of. I need to track the longevity of every capital asset outlay in order to maintain cognizance of my fixed costs of doing business. I need to know this in order to know whether i am bringing in enough money to meet those costs and stay in business long term. So, since i've got so mush different stuff to track valuation of, i use depreciation values and timeframes as an abstraction. It turns out that my roof depreciates to $1000 in 10 years and $0 in 15 years. Conservatively I then estimate that I will need to spend $10000 in inflation adjusted money in 10 years to replace the roof again. This makes my cost $1000 per year of operation.
So, tl;dr is so far everyone assumes that because the person in the story saves $3000 a year that somehow his solar system will last for 10-12 years to repay itself without repair. This is fallacious logic. Depreciation is a way of measuring whether and how much it will cost to repair/replace the system in what time frame. From that one can estimate whether return of investment is possible.

and you do this until you get to ((3.0 Gbps)/(8 bits/byte)) / (best case disk read speed in MiB/s) number of disks. Then you floor that to preferably a power of two or at least a natural multiple of a power of two.
This maximizes your bandwidth to the resulting filesystem.
e.g.
3Gbps = 402653184 bytes/s ~= 400MiB/s
i get some seagates with 75 MiB/s max sustained read.
400/75=5.3 -> 5 disks
5 is not divisible by a power of 2 (duh, its prime)
4 is the closest.
sector size is listed at 512bytes, so ideal stripe size is a multiple of 2KiB. This keeps your IOs clean and the disk cache happy and unfragmented.
meh. even with my online grammar and capitalization errors i'm still a better than average writer for an engineer. further the lack of capitalization is intentional: it is less formal and thus less pompous and pedantic. it also rarely gets confused for ONLINE YELLING.:)
since i work with digital logic, i'd hardly consider myself a pseudo logician, but you're entitled to your opinion. and while it may be an accident of history as you say, the fact remains that the usurpation of btq leaves those like yourself with two viable, commonly understood phrases and logicians and philosophers with zero. i think that's a bit greedy.
or maybe he was suggesting the intimidation he and his friends felt at being out of their element and in a new, strange, and oft stereotyped setting with real, if frequently overplayed, possibilities for eruption of violence.
maybe he over-empathized with those around him as a manifestation of his "white guilt". i know my primary inhibition with respect to new acquaintances from different American ethnic groups is my own self consciousness about the possibility of offending them. i think that sucks and we will only be able to make claims regarding the elimination of racism when *no one* has any particular feeling regarding their fellow man other than those merited by the facts of the interaction. (dude looking for a seat in the cafeteria: fine; dude robbing me: bad)
how else would you have described the setting to portray your feelings of isolation and perception of personal risk, justified or not? perhaps, "we were in a socioeconomically depressed region of town and felt odd"? this misses mounds of social context of both the part of the neighborhood denizens and the nerds.
racial tension is real. ignoring it and not communicating openly about these perceptions will not make them go away. in fact, lack of open communication will only stopper up and push these feelings underground where they will fester and gain new currency. on the other hand, i view this sort of description not as particularly racist, but as a step away from racism. can it be better, more harmonious, whatever? sure. gradually. as reality allows, descriptions of one's circumstances in odd situations will be based in that new reality that developed from today's which is, in turn, dramatically different from, yet traceable to our worst days as a racist society.
on a lighter note, isn't the term nerd a pejorative assigned based on extrinsic features observed by the cool kids? yet we own the term and generally rejoice in our nerdiness. and in our interactions with the world around us, we are gradually becoming normal in society.
perhaps because you have a self deprecating sense of humor?
amongst other things, i'm an American of predominately Scottish and Dutch descent, and i refer to myself by a large variety of slurs.
maybe we'd all be better off as a society if everyone just took a chill pill and enjoyed a good laugh at our own and each others' shared expense without getting so wrapped up in labels that most people don't even know the origin of.
too bad that its hard to measure passion in a classroom setting. i certainly can't think of ways to measure it objectively that control for the number of variables involved. so how do you identify and remove/reward bad/good teachers effectively and not have it devolve into a purely organizational political process? then throw the teaching unions' resistance to change/external review into it. it's disheartening.
you don't have to be a PhD. to be interested in and passionate about math. there are some very elegant things in math, and if they are taught to kids in the spirit of a voyage of discovery rather than a trudge along the banks of the river Styx, then there's a chance more kids will catch the bug and like math. And at the rate we're losing engineering capability, particularly in the US, this ought to be a priority.
it'd be nice if they'd each file amici briefs for each other's cases. the one defends the bulk of our liberties and the other defends the last line of defense of those liberties.
but note how the average of all justices over all time is 0.05. doesn't that just make you all warm and fuzzy inside about how balanced and stable our judicial politics are? no? you don't mean to say that numbers can lie, do you? or that people can set their numbers up to make the current political spectrum look normal?
You're not your job. You're not how much money you have in the bank. You're not the car you drive. You're not the contents of your wallet. You're not your fucking khakis. You're the all-singing, all-dancing crap of the world....
