Why does range(start, end) not include end?
...merate(x) rather than for i in range(len(x)).
Slicing works that way too: foo[1:4] is items 1-3 of foo (keeping in mind that item 1 is actually the second item due to the zero-based indexing). For consistency, they should both work the same way.
I think of it as: "the first number you want, follow...
What does a type followed by _t (underscore-t) represent?
...nstance, your program matches POSIX 1003.1 Issues 6 and you defined a type foo_t. POSIX 1003.1 Issues 7 is eventually released with a newly defined type foo_t. Your program does not match the new version, which might be a problem. Restricting the _t usage prevents from refactoring the code. Thus, if...
Static Indexers?
...me too - an example I tend to use is Encoding, where Encoding.GetEncoding("foo") could be Encoding["Foo"]. I don't think it would come up very often, but aside from anything else it just feels a little inconsistent not to be available.
I would have to check, but I suspect it's available in IL (Inte...
Removing an element from an Array (Java) [duplicate]
...se arrays, two calls to System.arraycopy will most likely be the fastest.

grep without showing path/file:line
... for a pattern within a specific directory, this should suffice:
grep -hn FOO /your/path/*.bar
Where -h is the parameter to hide the filename, as from man grep:

when there is only one file (or onl...
What is std::promise?
...example's sake, suppose we have a function that takes some arguments:
int foo(double, char, bool);
First off, we have the template std::future<T>, which represents a future value of type T. The value can be retrieved via the member function get(), which effectively synchronizes the progra...
How do I pick randomly from an array?

Just use Array#sample:
[:foo, :bar].sample # => :foo, or :bar :-)
It is available in Ruby 1.9.1+. To be also able to use it with an earlier version of Ruby, you could require "backports/1.9.1/array/sample".
Note that in Ruby 1.8.7 it exists un...
Android Studio: Add jar as library?
