SHELL ["/bin/bash", "-c"]

Can a class extend both a class and implement an Interface
...
Since you can only inherit one class and you can implement any number of interfaces, it was probably a syntax sugar thing. Also, remember, if your subclass implements any interfaces, that would show up in the list of implemented methods too. So putting...
How to check if a value exists in an array in Ruby
...
Note that if you have many values in your array, they will all be checked one after the other (i.e. O(n)), while that lookup for a hash will be constant time (i.e O(1)). So if you array is constant, for example, it is a good idea to use a Set instead. E.g:
require 'set'

There are two versions of the adapters that work with ViewPager, the ones in the v4 package are meant to be used with support fragments, the ones in v13 with native fragments.
The reason why there are now two fragment implementations is historical: Fragments in the android.app package were in...
How can I properly handle 404 in ASP.NET MVC?
...
Thanks for the full write-up. One addition is that when running under IIS7 you need to add set the property "TrySkipIisCustomErrors" to true. Otherwise IIS will still return the default 404 page. We added Response.TrySkipIiisCustomErrors=true; after the ...
Converting ISO 8601-compliant String to java.util.Date
...
Unfortunately, the time zone formats available to SimpleDateFormat (Java 6 and earlier) are not ISO 8601 compliant. SimpleDateFormat understands time zone strings like "GMT+01:00" or "+0100", the latter according to RFC # 822.

Split string with delimiters in C

@Dojo: It remembers it; that's one of the reasons it is problematic. It would be better to use strtok_s() (Microsoft, C11 Annex K, optional) or strtok_r() (POSIX) than plain strtok(). Plain strtok() is evil in a library function. No function calling the...
