There is manufacturing precision and there are "analog" tech tricks to get things done.
Print a brick that is a notch more "loose" than real Lego. Dip in the resin, shine UV to cure it halfway-soft. "Plug" into real lego to push the soft layer of resin to match precisely. Cure completely. If too loose, add another layer.
The beauty of manufacture engineering is that you can lie to the machine and make it create things it was not intended to do. Using tools it was never designed to work with, forcing it to do the same pass twice just to allow element flexibility to apply a layer that is beyond the machine's resolution, using purposely bad technological parameters to make parts brittle, weak and easy to remove, creating supports for the real pieces, doing an extra smoothing pass to remove material tension from the surface, using sub-size rough tools to allow "fine pass" to smooth out surfaces it would normally fly over, making the fine tools 5% larger than target size (within tollerances but if it's 0.4mm +-0.02mm, make it 0.42) to compensate for material flexibility/yielding under pressure... all kinds of tricks that make no sense from "numerical processing" point of view but get the stuff to be of quality surpassing the built-in capabilities of the machine.
...stupid people who download this malware. Just last month I was warned putty.exe was found in my system. Later tinyproxy was discovered. And I went even as far as installing VNC Server!
It isn't very long since I disabled the antivirus to download actual worm to the computer. Like, the guy got a webpage infected with some nasty stuff, and it embedded links to self in headers of the PHP files. So, to remove it, I had to download the PHP, edit out the infected lines and upload it back. But no, downloading php scripts (to a computer without a webserver or PHP interpreter) triggered a virus alarm and I would not be allowed to save the infected files. So I disabled the antivirus and downloaded the infected files right to my desktop!
Microsoft security engineers must really tear hair off their heads because of reckless users who allows this kind of malware on their machines.
So there is a significant difference between cost of wheels that are in the dishwasher and wheels that are not a part of it? Or do you purchase $40 wheels to install in $500 ($300 bulk) dishwasher before shipping it off to stores? If you add up cost of all parts it would appear that by assembling the dishwasher you reduce its price by 80%, because bought "in parts" it would be above $2000?
I'm not buying your bullshit. The material costs actually $0.02, the whole manufacturing and distribution would place the price around $1 and that's about the price the bulk manufacturer pays for the set of wheels for the dishwasher. The $40 is a bullshit price set to discourage repairs and encourage unnecessary purchases. It has no bearing on the real product value whatsoever (it's the same $1 set of wheels set aside for service, and it was shipped in the same container as the dishwashers, adding 300gram to the 15-ton load), but by pricing it at 40000% the real value you assure people will seek out to replace the whole dishwasher. With one that has parts designed to break as the warranty expires, to assure a new sale. Incremental improvements? bullshit. More like reduction of costs (by using shittier materials, thinner construction, cheaper alternatives) to allow better profit margin for the same price.
The primary reason this happened was that the coolant pumps (and diesel engines powering them) stopped.
Earthquake pretty much forces the huge, massive and ultra-precise steam turbines of the power plant to stop - these things require micrometer precision while in operation, so leaving them running is not an option - as effect primary power source of all systems is gone. Instead, backup power kicks in, diesel generators power up the coolant pumps and keep the core cool. But diesel engines need lots of air and if they get flooded, they stop.
In this case building the backup power and pumping stations on a high roof or elevated terrain would suffice. Sure -some- leak might have happened due to the earthquake but since the pumps would remain operational, there would never be overheating, explosion, extra water could be safely pumped in using normal systems and sealing any potential leaks could be done as a common repair.
Primarily, there would be no radioactivity leak. Reactor coolant water by itself is quite safe, being very clean it contains no material that could absorb radioactivity/become radioactive. It's the contamination from molten reactor material, debris, dust, ash and so on, dissolved in the water that carries the radioactivity. So even the coolant leak is not dangerous if water can be resupplied and is kept clean.
As long as it's xor'ed against white noise, no problem with me.
Digital representation of an image of a person is somewhat different from a random number that is not a representation of anything, just a random number.
RepRap can produce parts as big as this whole printer is big.
I think the finest detail size to manufactured object size ratio is on RepRap's size, and commercial application of this is primarily limited by absolutely tiny work area. And the resin is expensive. Sure this has its place where one needs tiny precise custom parts. But I believe objects bigger than a cubic inch are in higher demand...
So unless Valve is double-taxed (paying both european VAT and the US state/local tax on the same sale), they are making extra 9% on each sale. Exchange rate interest is near +/-1% of the average price (AND it's not included in Euro display price! Unless Valve converts, say, PLN->EUR->USD, paying exchange interest twice, instead of PLN->USD, then they charge the exchange rate interest extra, not average exchange price but dollar purchase price).
oh, BTW, I just checked. The price does not include exchange rate to local currency. I bought EUR9.99 game from Steam recently. The amount deducted from my account converted directly to Euro is EUR10.24. So no, the price listed is not higher due to exchange rate - and I doubt Valve first converts my local currency to Euro and then exchanges that for USD. If it contained exchange rate they would list 10.24, not 9.99
I found it pretty essential in web development. One screen for code, the other for docs and results. Browser permanently open on php.net, and the webpage I'm developing.
Most IDEs are designed to be used in full screen. If you reduce the window size, various toolbars, menus and extras remain in place while the editor area shrinks... to ridiculously useless size. You just need one full screen for it. And if you're to copy-paste stuff into it, a second monitor is a great boon.
Also, theoretically, increasing resolution would help. Only theoretically though. The screen isn't getting bigger, it's the content that is getting smaller. And my eyes are not getting any younger. (still, a HUGE screen in a very high resolution might work.)
Yes, it's busybox but you can still perfectly well make a fork bomb in it. It appears it has a display bug and shows " in place of & but this still works correctly, like an & should.
Fuck you, Valve, I have a choice between paying 40% more than americans or not paying at all. Guess which one I choose. I'm all open for honest exchange, but I have no qualms against screwing you if you try to screw me.
Less of a blind respect to authority. A western employee of the power plant would say "Fuck the CEO if he's not available - I'm venting it." In Japan, loyalty and obedience is worth more than "doing the right thing".
I wonder if the next logical step will follow the Chernobyl pattern.
After the Chernobyl disaster, a common effort by all soviet republic to give relief to victims of the disaster resulted in building a new city from scratch. Slavutych is the city of people from the Chernobyl zone. Employees of the power plant, veterans of liquidation of the disaster, foresters, guards and scientists maintaining the zone of exclusion live in a city 50km from Pripyat, and these currently employed in the zone are going the 60km to work by a train every morning. The town, population 25,000 is divided into 8 districts, each with unique style and character given by a chosen soviet republic that lead building it. The design was specifically intended to give people new hope, a consolation and compensation for what they lost. The plan mostly worked: the standard of living is one of best in Ukraine, and there is outstanding number of children in the town, making its average age the lowest in the country.
Now I wonder how would the counterpart in Japan look like, if Japan chooses a similar solution. A modern town built in a year or less from scratch, designed with keeping spirits up in mind, done by the Japaneese may be very interesting...
waitwaitwait. Packet loss might change the speed by random factors. But the GP gives exact "10-fold" which seems very much like a 10-100mbit or 100mbit-gigabit leap. And that's perfectly possible with incorrectly made cables.
Modern, large scale solar power plants don't use photovoltaic cells. Too high cost:efficiency ratio, the price of infrastructure doesn't scale up well. Instead, they use traditional approach with hot steam turning the turbine, and the solar energy is used to heat various working liquids - methanol, saline, or even liquid sodium.
In this case, a leak can lead to quite disastrous water contamination, and failure of the systems can be quite explosive and deadly to employees.
Still, the death toll at 4000-5000 is more reasonable. 50 is the number that died in the explosion or due to direct exposure at the location. Most of people observing the nuclear fire from (so called since then) "Bridge of death" at Pripyat received lethal doses. Many disaster recovery people died, and cancer rates soared. Of course the Greenpeace number accounts for pretty much every cancer case in Ukraine ever since...
The argument is primarily that workplace accidents at any power plant account for vastly more deaths than nuclear meltdown accidents. Solar has the nasty side-effect that it requires enormous number of panels to produce more energy. A solar power plant that would be capable of producing as much power as a large nuclear power plant would be likely so big - require so many people building it - that the number of accidents (due to sheer number of people working at building it) could easily dwarf a NPP accident rate.
Typical work safety failure with power grid infrastructure - servicing the grid without switching it off.
You can die from electric shock from electricity produced by solar power, at a solar power plant just the same as from coal or nuclear. Most casualties at power plants are related not to the energy-creation side (boiler, reactor, panels) but at the electricity management side, where you work with high voltages and currents that can fry you at a distance.
Plus some solar power plants work not by photovoltaic effect, but by heating water using solar collectors (or other working medium) and using it with traditional power plant turbines. You tell me what can go wrong with that.
So, if a two classes of 30 students each install each a pirated copy of a SCADA system, estimate sales value $250,000 each, to make their final work at the dorms/home and not in a computer lab, and without "student version" nag, that means the industry has lost $15mln to that school year alone?
Because surely the students would definitely buy the program if they could not pirate it.

There was a different project, that utilized similar approach but much better work area. http://blog.makezine.com/archive/2011/04/homebrew-liquid-resin-3d-printer-gets-resolution-boost.html
This actually has a potential to be cheaper, because it uses pretty normal LCD screen, not LED projector one with microscopic pixels.
$59.99 * 1.08 = $64.78
59.99 Euros = 84.91 U.S. dollars
Highest VAT threshold here: 23%
$84.91* 0.23 = 19.53 = VAT
$84.91* (1-0.23) = 65.38
$59.99 * 1.09 = $65.39

VAT is nowhere near 40%. Currency exchange margins never exceed 5%. And the american version isn't tax-free either.
