Detect permission of camera in iOS
...
A possibly useful tip – if you are testing code that uses this, you can't merely delete your App from the testing device and then re-instal. Doing this will not cause iOS to reissue the request to the user! What's worked for me though is to change the Bundle I...
Bower and devDependencies vs dependencies
...
devDependencies are for the development-related scripts, e.g. unit testing, packaging scripts, documentation generation, etc.
dependencies are required for production use, and assumed required for dev as well.

What is the Scala annotation to ensure a tail recursive function is optimized?
...the compiler.
In Scala 2.7 or earlier, you will need to rely on manual testing, or inspection of the bytecode, to work out whether a method has been optimised.
Example:
you could add a @tailrec annotation so that you can be sure that your changes have worked.
import scala.annotation.t...

How can I remove the first line of a text file using bash/sed script?
...l is much, much slower than the sed variant, by an order of magnitude. I'm testing it on a file of 500,000K lines (no more than 50 chars per line). However, I then realized I was using the FreeBSD version of tail (which comes with OS X by default). When I switched to GNU tail, the tail call was 10 t...

...velopment. Some libraries for older frameworks have undergone a decade of testing and bugfixing, and are very stable by now. Npmjs.org has no mechanism to rate packages, which has lead to a proliferation of packages doing more or less the same thing, out of which a large percentage are no longer ma...
How to make “if not true condition”?
...fic case, it does indeed work because sysa will be printed which makes the test statement come true. However, if ! [ $(true) ]; then echo false; fi would always print false because the true command does not write anything to stdout (even though the exit code is 0). That is why it needs to be rephras...

EOFError: end of file reached issue with Net::HTTP
...eached.html

@http = @http.start
url = 'http://domain.com/requested_url?blah=blah&etc=1'
req = Net::HTTP::Get.new(URI.encode(url))
