The cost per page for an inkjet printed document is orders of magnitude more expensive than a page from Joe's Offset Printing Shop.
You pay for the convenience. It's certainly not cheaper. It's especially cheaper to print with gold leaf than it is to print with inkjet ink from HP. It's cheaper to email your digital photos to a professional developer and get prints than it is to do photo prints at home. Consumer level equipment is expensive and inefficient per unit.
Everyone is so enamoured of the Star-Trek fantasy of replicators but they don't seem to realize that we're nowhere near that fantasy, and the reality is that until we have some really big breakthroughs in physics, we're not going to see a sintered metal salad fork less expensive than one you can get from someone who owns a power press. And costs are just waved away as if they don't matter.
Costs matter.
Rapid prototyping is great for demos and demo tooling and one-offs and art, where you might be able to recoup your costs or the alternatives are more expensive. Some sintered metal tooling applications are even suitable for short production runs.
But the example given by the other guy "why order cheap plastic stuff from China when you can just print it" is just nuts and ignores fixed costs and low production rates. If a rapid prototyping machine costs you $100/hr just to keep it around taking up space, you're not going to be printing salad forks for your lunch.
>Speed is nice but not the goal, lowing the cost of production would be ideal.
Speed is always a goal. Time is money. Cost is amortized over the number of parts you make. Your fixed costs of equipment, power, people, infrastructure, etc, do not go away. The more pieces you can make in a certain amount of time decreases the cost per piece.
>Why get your cheap plastic crap form china when you'll be able to print it at home for the cost of the plastic, you don't NEED 600 a minute.
Because a "do everything" printer that makes useful items (because useful items are a combination of materials, not just plastic) is expensive and power hungry. You can buy sintered metal printers, sure, but you don't want to be manufacturing your flatware with a machine in the basement that costs $100,000 plus the heat treating of the output. "The cost of the plastic" ignores the cost of the machine and the power needed to run the machine. This stuff doesn't work by magic, and I see arguments like yours that throw out "inconvenient facts" like machine costs all the time. And you just did it here.
You are *never* going to make a salad fork cheaper at home than some guy in a factory that has a power press. Ever. Because of efficiencies of scale.
NPR blogs has been doing this lately too with 20 point sans-serif. It's annoying as hell.
I seriously do believe that they are compensating for people who can't be arsed to adjust minimum font size (or dpi) on their own, or to even tell Windows to "use big fonts."
Wake me when a 3D printer can output something as simple as a pen clip at 600/minute (which is what you get out of a 30 year old press).
For rapid prototyping, yes, this kind of stuff is OK, because there is no demo tooling that winds up being production tooling (as is typical, bleh) and actually saves money. But to tout these kinds of numbers as if they're any meaningful amount of production is just crazy.

Where this cosmodrome is, used to be an ICBM site.
No, you can launch polar orbiting sats from nearly anywhere, it's where the bits fall that may be a problem.
The US launches polar orbiting sats from Vandenberg, because a launch failure or simply a spent booster means that it goes down in the Pacific instead of somewhere on the continental US or Canada (because the Earth rotates under it).
"Russia intends to eventually withdraw from Baikonur and conduct launches from the Plesetsk Cosmodrome, an operating spaceport about 500 miles north of Moscow â" and the unfinished Vostochny Cosmodrome in the Russian Far East."
200 miles south of Arkhangelsk? Really?
As one moves further north, one loses the assist from the Earth's rotation. Launch anything easterly from the Equator, and you get slightly more than a 1,000 mile per hour boost to orbit. If you want to save fuel and cost, you try to launch from as far south as you can, which is why we launch from Florida instead of Cape Cod.
(24902 * cos(63))/24
24902=Circumference of the Earth 63=Latitude of the Plestsk Cosmodrome in degrees 24=Hours in a day.
471mph/758kph - it's the worst out of all of them.
Vostochny Cosmodrome is 51 degrees N. 653mph/1051kph
Baikonur is roughly 46 degrees North - 720mph/1160kph
Canaveral is 28.5 (roughly) - 912mph/1468kph
Centre Spatial Guyanais - 5 degrees N. 1034mph 1664kph - the ESA gets the biggest boost.
Unfortunately for the Russians, they don't have anything very far south. The furthest south they can go is the southern end of Dagestan at roughly the same latitude as New York City.

... what "fully updated" means. It certainly sounds like the author thinks that the latest distro and kernel is what's recommended.
It's not.
>Ubuntu 12.04
Valve is recommending the LTS and not 12.10, as well they should. Recommending the latest kernel and distro is asking for nothing but pain for everybody involved.
As far as the hardware recommendations go, they're not outrageous either.
But that still means that 100,000 recaptchas costs $1,000 US and it doesn't guarantee that Google's botnet detection won't see you before you've used 5 percent of that.
>All captcha technology which I am aware of has been defeated by bots. If you know of one which isn't please tell me, so I can secure my forum from spammers.
Recaptcha hasn't.
4chan has been using it for quite some time now in conjunction with proxy detection/banning. Before Recaptcha, 4chan had a huge malicious spam problem (posting of malware embedded in images). The only way to defeat it is to pay fo an Indian service like 10 cents US per recaptcha, which means that "S.R. Patel" is sitting in a cybercafe in Mumbai interpreting each recaptcha by hand. This is terribly time consuming and inconvenient for a lot of spammers who go on to softer targets. Spammers need stored captchas in the hundreds of thousands to make forum spamming effective. Typical Indian prices (10 cents/recaptcha) make this too expensive.
Slashdot, for example, uses Recaptcha for anonymous posts. You don't see a huge problem with spam here, do you? Oh sure, one or two get through, but as a percentage, it's minuscule. It's nothing like the flooding we had back in the 90s.
The combination of proxy banning and Recaptcha is for all practical purposes, impenetrable. How long this will last remains to be seen.
Fark has defeated forum spam by disallowing anonymous posts altogether and making users wait 24 hours before an account becomes active. Spammers don't want to wait. It's a waste of time for them. They also have a pay section called Total Fark. I belong to a forum called Investor Village which is subscriber-only to post, and has a TOS that goes back to the good old days of "Unprofessional Behavior Is Bannable" which Blue doesn't exercise often, but the account death penalty has been weilded in the past.
Getting back to Recaptcha, this is what Scritty had to say on Blackhatworld:
Re: captcha solver - recaptcha
None available.
Google make changes to recaptcha almost daily.
Someone coded one about 6 weeks ago - lasted about 48 hours
Every Recaptcha solve attempt call goes straight to recaptcha headquarters (which is a google product)
If they sniff automation - they change the code. If they get bored - they change the code. Basically - they change the code all the time.
One day OCR will be that good that it can sort it out, but I've tried every bot solution you can find, and none even get close. (Xrumer, platimum captcha, captcha sniper, magic OCR..none of them work even close)
