What's the best visual merge tool for Git? [closed]
...author is using?, the question is general enough to be of interest to everyone who looks for it. And 3-way diff is when you actually see 4 panes with test; merge-base/local/remote/result

What's better to use in PHP, $array[] = $value or array_push($array, $value)?
...enchmarks, but I personally feel like $array[] is cleaner to look at, and honestly splitting hairs over milliseconds is pretty irrelevant unless you plan on appending hundreds of thousands of strings to your array.
Edit: Ran this code:
$t = microtime(true);
$array = array();
for($i = 0; $i < 1000...
SQL update fields of one table from fields of another one
...agree with @cluesque, but this answer is an excellent way to use values in one column in a table as a lookup table for replacing values in a column in another table (see SO 21657475), so +1 ...

Where does Scala look for implicits?
...alue that can be passed "automatically", so to speak, or a conversion from one type to another that is made automatically.
Implicit Conversion
Speaking very briefly about the latter type, if one calls a method m on an object o of a class C, and that class does not support method m, then Scala will...
How to find and return a duplicate value in array
...}
I know this isn't very elegant answer, but I love it. It's beautiful one liner code. And works perfectly fine unless you need to process huge data set.
Looking for faster solution? Here you go!
def find_one_using_hash_map(array)
map = {}
dup = nil
array.each do |v|
map[v] = (map[v...
Should 'using' directives be inside or outside the namespace?
...{
double d = Math.PI;
}
}
}
Now imagine that someone adds another file (File2.cs) to the project that looks like this:
// File2.cs
namespace Outer
{
class Math
{
}
}
The compiler searches Outer before looking at those using directives outside the namespace, s...
Ruby Regexp group matching, assign variables on 1 line
...ng like this:
#!/usr/bin/env ruby
string = "RyanOnRails: This is a test"
one, two, three = string.match(/(^.*)(:)(.*)/i).captures
p one #=> "RyanOnRails"
p two #=> ":"
p three #=> " This is a test"
Be aware that if no match is found, String#match will return nil, so something like ...
How to convert a data frame column to numeric type?
...
Here goes: first two columns are character. I've deliberately called 2nd one fake_char. Spot the similarity of this character variable with one that Dirk created in his reply. It's actually a numerical vector converted to character. 3rd and 4th column are factor, and the last one is "purely" numer...
Chain-calling parent initialisers in python [duplicate]
...
The way you are doing it is indeed the recommended one (for Python 2.x).
The issue of whether the class is passed explicitly to super is a matter of style rather than functionality. Passing the class to super fits in with Python's philosophy of "explicit is better than impl...
How do I pass a string into subprocess.Popen (using the stdin argument)?
...e Popen object with
stdin=PIPE. Similarly, to get anything
other than None in the result tuple,
you need to give stdout=PIPE and/or
stderr=PIPE too.
Replacing os.popen*
pipe = os.popen(cmd, 'w', bufsize)
# ==>
pipe = Popen(cmd, shell=True, bufsize=bufsize, stdin=PIPE).s...
