When a police officer is around you, you are being surveilled - by the police officer. If you're doing anything illegal in front of the police, expect to get in trouble. Police wear uniforms and are easy to spot. That's very different from having concealed cameras everywhere.
Recent comments by Alan Greenspan paint a dire picture of primary education in the United States:
"We cannot manage our very complex, highly sophisticated capital structure with what's coming out of our high schools."
"If we're not going to educate our kids, bring in other people who want to become Americans."
Under such dire circumstances and an existential threat, now is not the time for bias.
Sorry, old Unix guy here. My first reaction was "What the F is pkexec and why is it running setuid?"
Yet another way to execute arbitrary privileged executables is yet another potential security hole. This dumb thing is apparently part of the "Free Desktop" but it's depended on by all kinds of stuff including the fricking RedHat power management. What's wrong with plain old sudo?
No, that's not right. You have to pull the finger. I'll show you. Pull my finger.
Because the new is often outweighed by disadvantages, perceived or real.
Apple offers a server variant of OS X as well.
I think you might have meant SOAP, not XML. There are plenty of people writing REST services that speak XML.
The question is, who is "you" and when does that checking happen? I don't do a lot of work in Python, Ruby, etc. and all of the programmers that I know who do are fairly young and working on fairly small projects so they don't have a good answer for refactoring.
If I change the arguments to a method in a statically type language any place where I forgot to change the call to that method will be exposed at compile time. As far as I've been able to learn so far, in most dynamically typed languages that check won't happen until runtime. The pat answer to that is "you should have unit tests that cover everything" - but getting complete code coverage is hard and for large projects, the test suite takes a non-trivial amount of time to run - usually much, much longer than compile time. So, you wind up with bugs at runtime. Or is there a better solution?
Those farms of x86 boxes aren't necessarily running the same OS on each, necessitating different JVMs. I've personally worked in server environments where the same code had to run on x86 machines under Windows, Linux, HP-UX, and Solaris simultaneously.
OK, that's bullshit.
Technically, I see how it works but why would a merchant accept this thing? It doesn't look like a credit card and it's missing all of the anti-fraud elements built into the physical cards. According to their FAQ, Coin is trying to substitute an image on your smart phone plus their gadget for your physical card but I don't see that any of the actual credit card issuers are actually endorsing this. As a merchant you might be in violation of your merchant agreement by accepting this thing.
The Blu-ray disc needs to be mounted before it can be accessed. The ratio of robotic mechanisms to discs becomes important. If you need to mount ten discs, it takes ten times as long (if they're all using the same arm) whereas you could spin up ten hard drives simultaneously.
I've worked with large scale robotics since the late 80's. The performance of the arms has not increased significantly since then. When you're dealing with scientific datasets or backups it's not as much of a problem. In random access storage, though, it starts to be an issue.
Something like a Meade ETX-80 isn't terribly expensive, the alignment procedure is easier, plus you get the benefit of go-to functionality with automatic tracking which really helps those that don't know the sky yet. German equatorials really are only necessary for photography, IMO, and are a royal pain in the butt to deal with when the optical tube is of any appreciable size.
My 10" Dob works just fine with an equatorial platform, and the platform costs a LOT less than a decent German mount that can deal with a 30 pound tube.
