And what is the difference between "open" and "run" ?

If you are at a system level, of course windows makes a difference between open (as in "give me a handle to a resource") or run (execute code).

If you are at a GUI level, and it's probably what you are thinking about, it's not about windows or linux or whatever, it's about the program you are using to do the "open". When you are clicking on an URL or an email attachment, the browser or mail program decides what to do with it.
On windows, many apps use the "ShellExecute" action with the default action which is the same as double-clinking a file on the desktop but it is not the only way to do it. On linux, there isn't a standard way of opening files so it's really app dependent.

Maths can be very concrete (simple arithmetic) or very abstract (number theory, which is also called arithmetic).
Programming can be very concrete (assembly) or very abstract (pure functional)
Human language can be very concrete (dog training) or very abstract (philosophy)

Maths can be very lax (estimation) or very rigorous (formal proof)
Programming can be very lax (visual programming) or very rigorous (certified code)
Human language van be very lax (slang) or very rigorous (poetry)

VR developers are totally aware of the lag issues.
Judging by the posts of John Carmack and Michael Abrash it looks like it's they number one priority. 120 Hz seems to be their target now, and that's just because 1000 Hz would be too expensive ;)

hosts files are a common attack vector, this is why OSes tend to limit its use. It's also a bit limited as a way to block ads.

There are plenty of other ways : xposed modules such as minminguard / youtube adaway / unbelovedhosts, proxy servers, alternative dns, adblockplus for firefox mobile, pay for "pro" (no-ad) versions of apps, etc...

The two last points are very effective (especially the last one :p) and do not require root.

Does it means that if a bisexual sexually-as-in-sex-act harass people of both genders, that's not sexual harassment ?

If you are so keen on raging, try to talk about quakes.

Well, I expect computers to become really good at law.
The big idea with legal systems is to refer to some written laws and precedents rather than the whim of the judge. Basically it's a search problem and it's one of the things that computers do best.

These bitcoins probably weren't intended to stay as bitcoins forever.
The flow probably looks like this : buyer uses USD to buy BTC, buyer transfers BTC to seller, seller sells BTC to get USD. That's pretty much the definition of money laundering.

Even if technology can give us everything we need with no actual human work (i.e. infinite efficency), we are still social animals.
It means that people will gladly pay just so they can interact with actual human beings.

Writing small, tricky, code require a certain set of skills but I believe that the mark of great programmers is the ability to scale up. That means writing clean, efficient and flexible code even on large projects.
Demos for example may look impressive but due to their non-interactive nature, they can use plenty of tricks that won't work in more general cases.

It's actually a serious punishment if it's just the act of using the DB for personal reasons.
If you are using that info to commit another crime, you will probably get a second aggravated sentence.

I don't know how it is in the US but in France, many pedestrians don't give a fuck about signals so we might as well remove them.

I believe that the reasoning is :
- diversity is good
- finding minorities with the required skills is hard
- hiring under-skilled people just because they are minorities is bad
=> we need to give minorities the required skills

I think it is some kind of a long-term experiment, an attempt to increase diversity without compromising skills.

If you have a light aircraft you can pretty much bomb anyplace you want. Areas directly over sensitive facilities are usually prohibited zones, which means that if you penetrate them you may be "pulled over" by a fighter jet and face big trouble after you land. They won't shoot if they can avoid it.

Trouble is, these zones are usually pretty small compared to the speed of even a small plane. For example, if you have zone with a 10 NM radius and you are flying at 120 kts, it only takes 5 minutes to reach the center. During this time, they have to notice you, dispatch an interceptor airplane, intercept you, send you a few signals, notice that you don't intend to comply and finally shoot you.

I don't consider phones without user replaceable batteries "quality design". For real quality oriented design, the goal should be "as long as a network exists". And considering that batteries are expected to last for about 3 years, they make for an obvious planned obsolescence.
My old Nexus One is still in use today( although not my me and with a new battery) and there is no reason to dump it as it still works as well as it did when I bought it. The 2 or even 3 year smartphone is a pure fabrication. For normal (non-geek) people, keeping a smartphone for 5-10 years should be the norm.
