Never mind that the threats she received would be enough, were she to be, say, a politician, to probably get FBI involved and some people at least arrested for 24 hours to scare them off... So much for equality...
There is a very, very good reason: their US market is nothing to scoff at. They make it here, they get the economy stronger, they boost a major market of theirs. It's quite simple, really. As far as slightly reduced profits go: they hoard them as cash, it's not like the investors care about profits because they see none of them anyway except from slowly climbing valuation of the company. The only way to make decent money off APPL stock as an investor is to ride the ups-and-downs and do short term trading.
As with anything, where there's demand, there'll be affordable solutions. You'd expect a larger selection of percussion drills and electric hammers/chisels in, say, German home improvement store than in American one. Heck, in a German store you'd also find a couple decent concrete saws, too. It doesn't have to be labor intensive if everyone around knows how to do it properly.
You can build a perfectly sound and long-lasting home out of untreated wood. There's plenty of novice mistakes that handymen and unskilled people do when maintaining wooden frame homes. Watch some Holmes on Homes and Holmes Inspection, you'll see a whole gamut of what people get wrong.
You need proper, specialized tools for working with and modifying either construction.
With wooden framing, you need, for example, a flexible drill/puller and snake to do wire pulling behind drywall. You need a proper knife and straight edge / square to score drywall properly. You need a manual drywall saw ("knife"). You need a sawzall (reciprocating saw) to cut fasteners when modifying framing. You need drywall finishing tools.
With brick/concrete construction, you need a percussion drill, a hammer drill/chisel combo, some hand-held chisels, and masonry working tools, perhaps a wet saw would be nice too if you want finished cuts on brick or blocks.
I wouldn't call either construction necessarily less involved when modifying things, you probably need same amount of experience to properly frame and finish a partition wall as you'd when doing a brick or plaster block partitions.
Any house that has brick or concrete walls is the same in this regard, and such homes are all over Europe and noone gives it much thought. You just learn how to use a jackhammer. I re-did plumbing in my mother-in-law's apartment -- it was of precast concrete construction. Sure it was a dusty job, with every hole and recessed run having to be chiseled out. With experience it got much quicker towards the end of the job. Yay for glued PVC pipes, too.
Not really. There is no alternative to rebar. Those are crack-prevention techniques, rebar is actually carrying structural loads, you'd need a heck of a lot of plastic to carry those.
If a house would be properly designed, like - say - an airplane, where every hole and every fastener is on the drawings, then even a framed house could be very, very easily prefabricated yet still assembled on site. The assembly would then be a much quicker process.
So you start with a CAD drawing that has every piece of lumber, every fastener, every wire, pipe and duct run, all the insulation, vapor barrier, etc. Every piece of lumber (studs, joists, etc) can be pre-cut, pre-drilled and pre-marked using relatively simple machines. Marking is there to identify (number) every piece of wood, and to mark locations of other pieces that mate with it. You'd also want the machine to identify crown direction and align all pieces of wood so that when you put up a wall it can be properly leveled and the drywall won't bow. When you do it manually, a bit of distraction and you can miss it. Heck, you'd also want all the pieces measured for true cross-section dimensions, so that any variation in thickness and depth can be acommodated for in sizes of perpendicular members of the assembly. For exterior walls, the changes in lumber depth (larger dimension of the cross-section) would be all taken up from outside of the house so that the drywall doesn't crack when you screw it down. For interior walls, you'd want the machine to either mill it down to calibrate the cross-section depth, or you'd simply select the pieces if the project is sufficiently large.
Any modified concrete blocks for the foundation are either modified using CAM machines, or 3D printed. All pieces of wire and tube are cut to length (with necessary extra length for inside of boxes/panels as required by code). All attachment points for wire, pipe, ducts are pre-marked so that all that you do is string a wire through a pre-marked path, staple it / clamp it down where marked, pull through predrilled holes. Same for forced air ducting: every piece is pre-cut and marked, you assembled it as it were a LEGO house. Pipes: same thing, whether it's copper, plastic, PEX, you name it.
This would still allow a more-or-less traditional style of building, but all the jobs would take much less time since you have no guesswork, all the pieces go where you want them to, and all the tolerances are tight. Of course the order of assembly would be important so that tolerances wouldn't stack the wrong way, but this can all be pre-engineered in advance. There should be further tools that I normally don't see used. Say, for putting framed walls together, you'd want a quick-release clamp to square the stud to and press it against the plate, then you drive screws or nails through the guides. Every joint is then repeatable. You'd probably have many such jigs for different jobs that call for precision/repeatability.
I remember in the elementary school we were doing some crafts projects that involved cutting and nailing wood together. With my dad we'd draw everything out, cut all the pieces on a bandsaw so that they didn't look like crap, pre-drill all the nail holes as I didn't really have the nail-driving fu as a 10 year old, and so on. In the classroom it'd take me maybe 15 minutes to put it all together and it was reasonably pretty. Everyone else had it done in 4-6x as long, and the results were worse looking, and they were dead tired at the end of it. There's nothing fundamental about framing that says the cuts have to be done on site. It's cheaper for a machine to do it. Not only because the cost of operating a fast machine may be lower than the labor cost of a framer who cuts every piece on site, but also there are no mistakes, and cut patterns can be globally optimized across the whole project to produce least amount of wasted lumber. I presume that if you'd optimize it over a whole subdivision, there could be significant savings in lumber that way.
Same goes for carpeting: imagine the savings when you can industrially pre-cut carpet for say a dozen houses, the scrap would be minimized, and the carpeting folks
Presumably, such homes could cost way less if the land is reasonably priced. All this points to, though, is that we need way more very highly skilled workforce: we need engineers, there are really not as many job for very low skilled labour around. That's the price we pay for our lifestyle, and the available workforce seems to be 2-3 decades behind the curve. There simply are no more low-skilled jobs around, and there will be less and less. For U.S. to maintain its lifestyle, in about 50 years you'll need almost completely highly skilled labor force: say 50% of population will need to be at the skill level of a decent engineer.
That's just plain old exaggeration. Why the heck would all homes look the same? Those techniques make it easier to modify the plans! As for coping joints: if it's done right, it'll look like a CNC router did it. That's why, ultimately, you want a CNC router because the labor and potential for wasted material is just too much. This has got nothing to do with cookie-cutternes, what the heck, do you look at every coping joint to make sure they all got no repeating imperfections?!
You're right, but only to a point. What I meant by "simlistic" was really idealized: they ignored too many known facts so the experiment is simple but pointless: it cannot provide any decent conclusions.
You should have perhaps asked someone who knows a bit about it, since those are all problems with known solutions. A GPS receiver that you can buy for less than USD $1k won't give you anwyhere near the accuracy you can pull out of the signal in realtime without using any differential techniques at all. For about $15-$20k in gear (multifrequency receivers with phase processing and ionospheric correction, large antenna, etc) you can get a couple mm of error in real time. Add to that another "nearby" receiver for a differential setup and your relative error can drop to well under a millimeter. Be prepared to spend good money for that. A good car's worth.
Nanostrain is a unitless unit. It means 10^(-9) in/in -- inches per inch. It's a relative measure of deformation, it always needs to be a applied to a length to give length. Just to look at orders of magnitude: 10 nanostrains over 100 miles = 10^(-6) mile = 0.6 in.
Quick defrag probably does it too. The way I do it is: 1. Analyze 2. In file list, select all files 3. Defrag
You'll probably see some files that have thousands or tens of thousands of pieces, and sqlite database(s) owned by firefox should be among them. That's my experience at least.
As for image decompression, I'd personally want it not to decompress anything that's not displayed. After all, you don't need to decompress just to know how big an image is. When you start scrolling around, it can figure out what images will be visible, for potentially how long, and how soon, and it can make decisions based on that. If I'm scrolling over some text with images, it'd be OK if the images don't appear for very short time as I scroll over them. Methinks that decompressed image cache should trade off memory for CPU usage, most machines are fast but short on memory methinks.
There's probably an sqlite file or two that firefox uses that has thousands or tens of thousands of framgents spread out all over your drive and is killing performance. Shut down your firefox, run ccleaner to consolidate the firefox database(s), then run a defragmenter in a mode that only coalesces files (defraggler has such a mode), it shouldn't take too long. This seems to work wonders. I only do free space defragmentation (full defragmentation) once a year. You'll be amazed how bad NTFS is at fragmentation, and if you keep updating firefox, its application files and files in your profile will be literally all over the hard drive.
I don't think one necessarily needs avoidance of hell as a reason not to be a dick. RNM is demonstably beyond help. There are some people who just don't ever give a shit and they are perfectly capable of screwing everyone around, but they have very good intentions all along and they are self-deluded in their belief that they are somehow doing good.
Frankly said, basing the choice of a database just on availability of relatively simple GIS indexing is somewhat silly. There's a lot of other costs that need to be considered, besides just how much the initial license will cost. You'll want test servers, licensed to take the number of connections needed to do stress testing. I have no clue how MSSQL licensing would work here. You'd probably want to be able to expand capacity quickly if the project gets major publicity (shlashdotting, a segment on it on NPR or whatever is the Canadian equivalent, etc). You'll want to figure out how long is the support on whatever platform you run the database on, and how much you'll have to pay to upgrade it when the time comes. There's the issue of project's long-term viability, too, I think that mysql has rotten smell to it at the moment. IMHO postgresql smells much better, it seems like it's moving ahead at a stately pace but it's always moving ahead. And hey, it does all the gis you'll need.
I agree. Copper really needs to be electrolytically machined for any sort of volume production I've been told. I've seen the process, and while it's "nasty", the results are accurate and repeatable, and there's no swearing involved as far as I could tell:)
There's plenty of very expensive tools for dealing with electrical copper wire and terminals: hydraulic shears, crimpers, etc. Properly attaching terminals to a 1" diameter wire requires probably $25k worth of tools.
Empathy and idolization are not synonyms, you know. It's mindboggling that people get seriously upset about some soewhat silly and negative comments about a dead person, yet are first to call the living posters of such comments all sorts of names. Apparently plenty of people have the dead higher on their priority list. Now that's an interesting observation. Thinking "less" of a dead person because that person was an MCE or whatnot is taboo, but classifying plenty of alive-and-feeling-it posters somehow inhumane just because they dare talk down a dead person is fine and dandy? The fuck? Do they deserve less empathy simply for being apparently wrong and alive? How dare they, right?
I'm not arguing that most of the talking-down posts are borderline trolling or flamebaiting, but the visceral response they elicit is truly uncalled for. I know empathy allright and I dare say you don't know me enough to know otherwise (a few posts is not enough). Yet the visceral trigger-happy speakers-for-the-dead are demonstrably confused about demonstrating theirs. Just to make it clear: it doesn't work that way.
It won't do anything to the dead teenager at all, duh. The memory of her is in everyone's individual mind, it's not like "negative" comments will change your individual memory of a person (they shouldn't!!). You're unnecessarily assuming that the posters you disagree with are slamming the person. Maybe they are slamming a certain way of idolizing the dead, perchance? I find it fairly disgusting on principle. If you wouldn't have written something a day, a week, a month or maybe even a year before the person dies, perhaps the death shouldn't change what you write? You see it all over the place.
Or perhaps they don't even have a lack of empathy. Perhaps they just don't feel the same way that you or others do about certain things. You know, they have different priorities than you. What they care about may be different than what you care about. And vice versa.
There's lack of empathy, and then there's idolization of the dead. Neither is cool.
Yes, a good life has been lost, and her story is pretty cool, I agree. Her life philosophy is certainly not unworthy of adoption. But let's not go overboard. The story is interesting, it belongs on the main page of Slashdot. Taking some of the "lacking in empathy" comments too seriously may be a social dysfunction too, yaknow.
