Who do you think will make these 3D printers ? Obviously not American companies.
I believe the point here is to promote mass production of 3D printers by offering a 400000 unit order to whoever can build these cheaply. If they manage to drop the price of entry-level 3D printers to say, sub-$100, there may be a huge market waiting for them. This, or the result of corruption by 3D printer manufacturers.
Why schools ? First : if they are to build 400000 3D printers, at least put there somewhere they can be used, second : kids working with 3D printers may become future customers, third : investing in education is good PR.

You can still do it, but it is more complicated now. Google took this measure to prevent installers from bundling unapproved chrome extensions.

Not necessarily : taxi fees are regulated, Uber fees are not.
In Bangkok for instance, official taxis are one of the cheapest mode of transportation, especially if you are a tourist. Because prices are regulated, they can't overcharge you (although some may attempt to scam you by not using the meter).

The problem is not FTP, it would have been the same with HTTP or any protocol that allows anonymous access to files. Although it is uncommon, you can even do it with with SFTP.
The issue is that people are making private files public through misconfigured routers, and Google's crawler is very good at finding and indexing anything public.

I think it is stupid.
Ok, having children is more damaging to a female career so let's make it more damaging to males too, let's make the couple's global revenue less, because, yeah equality. Biologically, men and women are different. Men can't breastfeed for example. And there is this small thing call pregnancy too.

It's not that fathers don't deserve time with their kids, but newborn babies are clearly a woman's thing (except in special cases like adoption). The only thing a man can do is support, and it includes financial support.

Yes it's true that round manhole covers can't fall down but there are plenty of ways to make sure that manhole covers with other shapes don't fall down : supports, ties, hinges, proper handling procedures, etc...
I believe the primary answer is much simpler : because manholes are round, and manholes are round because it is good shape for a human to fit into, it resists pressure well and it is easy to make.

Additionally, not all manhole covers are round. For example, there are square manhole covers, and they usually cover square holes. Because what's good in most cases isn't always good in every case.

Before :
Interview with a woman :
- Pay is X
- Ok (final pay : X)
Interview with a man :
- Pay is X
- I want 20% more
- I give you 10%
- Ok (final pay : X + 10%)

After :
Interview with a woman :
- Pay is X
- Ok (final pay : X)
Interview with a man, case 1 :
- Pay is X, no negotiation
- Ok (final pay : X)
Interview with a man, case 2 :
- Pay is X, no negotiation
- I quit

So yes, equality : take the lowest salary and make it the standard. As for men or women with good negotiation skills, they will simply look elsewhere.

In Simpsons tapped out, a typical time-waster of a moblie game, free with premium content, players found an exploitable bug allowing them what is basically infinite money. IIRC they handled it this way :
- they fixed the bug
- they referred to the hack an in-game event (the moral being of course : you won't get any fun by hacking)
- they gave a special item to everyone that didn't use the exploit
- they didn't penalize those who did (except by not giving them the special item)

I found it was a wonderful way to handle the situation : they didn't punish the hackers, they simply told that the non-hackers were way cooler.

Tabs are fine but unless you and your team have a lot of discipline, it can result in a huge mess. Spaces are much easier to manage.

Common problems with tabs are :
- Trying to align code with tabs (tabs are for indentation only !)
good :
[TAB]int.....a;
[TAB]float...b;
bad :
[TAB]int[TAB]a;
[TAB]float[TAB]b;
- Copy-paste behavior may be inconsistent (for example terminals or browsers can convert tabs to spaces automatically)
- You can insert an invisible space between two tabs, and this can mess up diffs

They probably do, but maybe he was on holidays and he forgot to relay the notification to the person replacing him, at the same time the guy responsible for the SMTP service saw the problem but because it's the job of guy of the SSL service, he didn't do anything and...
No company is immune to this kind of problem, and certainly not the big ones. I've seen extremely stupid things, such as a power outage because the company forgot to pay the utility bill despite several reminders.

When I look around my home I see mostly multi-material complex objects (like electronics) or items that are not economically viable to 3D print.
Mass produced items use just the right material and the right process so that it can fullfill its function while optimizing costs. As a result, it will always end-up cheaper.
On a personal level, I think the exception is art : figures, decorative objects, jewelry, etc... And even then, you need to actually have a relatively precise idea of what you want, because if you merely want something nice, your tastes are probably similar to enough people to make mass production the way to go.

A good example is the painting you purchaced at the art museum even though you could have printed it on a sub-$100 desktop printer. Of course you could argue that a print is not a real painting but how about things like calendars, books, posters, maps, playing cards, etc... Some people do this but they are a minority.

3D printing becomes much more interesting in the industry, where it is used extensively right now. It enables rapid prototyping, making of uncommon replacement parts and even market testing (release a 3D printed product and if it works, switch to mass production techniques).

You don't need to trust the NSA for GP's argument to be valid.
If you need to protect your house, think about regular robbers rather than Arsene Lupin. Not because you trust Lupin, but because he is both less likely to target you and harder to stop. As a result, your countermeasures are much less likely to have an effect on the outcome.

Paris metro line 14 is fully automated. There isn't even a driver's cabin.

Athletes certainly run fast and jump high in well defined conditions but the Fosbury flop is clearly not the best way to jump over fences.
A parkour team would probably do much better considering that obstacle clearing is their specialty.

A deflagration simply means that the expansion of gases is subsonic, as opposed to a supersonic detonation.

Anyways, whatever the cause is, when stuff rapidly expand, it is an explosion. So they are right in pointing that hydrogen buildup and ignition is a deflagration and not a nuclear explosion but it is still an explosion.
