Using Build Flavors - Structuring source folders and build.gradle correctly
...two flavor you'll need to create it in both flavors.
src/flavor1/java/com/foo/A.java
src/flavor2/java/com/foo/A.java
And then your code in src/main/java can do
import com.foo.A
depending on the flavor selected, the right version of com.foo.A is used.
This also means both version of A must hav...
Understanding the map function
...call, comprehensions are faster? E.g. I was led to believe that map(lambda foo: foo.bar, my_list) is slower than foo.bar for foo in my_list, and that even map(operator.add, my_list_of_pairs) is slower than x + y for x, y in my_list_of_pairs, precisely because of the additional function call.
...
Given a class, see if instance has method (Ruby)
...since respond_to? restricts itself to public methods by default, as well.
Foo.public_instance_methods.include?('bar')
In Ruby 1.9, though, those methods return arrays of symbols.
Foo.public_instance_methods.include?(:bar)
If you're planning on doing this often, you might want to extend Module ...
What does __FILE__ mean in Ruby?
...
It is a reference to the current file name. In the file foo.rb, __FILE__ would be interpreted as "foo.rb".
Edit: Ruby 1.9.2 and 1.9.3 appear to behave a little differently from what Luke Bayes said in his comment. With these files:
# test.rb
puts __FILE__
require './dir2/test.rb...
Redirect all output to file [duplicate]
...
That part is written to stderr, use 2> to redirect it. For example:
foo > stdout.txt 2> stderr.txt
or if you want in same file:
foo > allout.txt 2>&1
Note: this works in (ba)sh, check your shell for proper syntax
...
RegEx: Grabbing values between quotation marks
...
@steve: this would also match, incorrectly, "foo\". The look ahead trick makes the ? quantifier possessive (even if the regex flavor doesn't support the ?+ syntax or atomic grouping)

Why have header files and .cpp files? [closed]
...alue. Then, implicit conversions happen. And then, when you have the code: foo(bar), you can't even be sure foo is a function. So the compiler has to have access to the information in the headers to decide if the source compiles correctly, or not... Then, once the code is compiled, the linker will j...
Optional Parameters in Go?
