A rebase switches the meaning of "ours" and "theirs":
git checkout topic
git rebase master # rebase topic branch on top of master branch
Whatever HEAD's pointing to is "ours"

do './config.pl';
This will read in the contents of the config.pl file and execute it. (See also: perldoc -f do.)
N.B.: Avoid do unless golfing or something as there is no error checking. For including library modules, use require or use.
If you need to use the ^ character in a character class (Character classes ), either put it somewhere other than the beginning of the class:
[12^3]
Or escape the ^ using a backslash \:
[\^123]
If you want to match the caret character itself outside a character class, you need to escape it:

func doSomething1(value: Double) { /* ... */ }
func doSomething2(value: UInt) { /* ... */ }
let x = 42 // x is an Int
doSomething1(Double(x)) // convert x to a Double
doSomething2(UInt(x)) // convert x to a UInt
Integer initializers produce a runtime error if the value ove...
Counting the keys of a Mapping isn't possible with collections.Counter but we can count the values:
from collections import Counter
adict = {'a': 5, 'b': 3, 'c': 5, 'd': 2, 'e':2, 'q': 5}
Counter(adict.values())
# Out: Counter({2: 2, 3: 1, 5: 3})
The most common elements are avaiable by the m...
