Where can I learn how to write C code to speed up slow R functions? [closed]
...as hundreds of packages, some from authors you trust. That provides real, tested examples to study and adapt.
But as Josh suspected, I lean more towards C++ and hence Rcpp. It also has plenty of examples.
Edit: There were two books I found helpful:
The first one is Venables and Ripley's "S Prog...
force Maven to copy dependencies into target/lib

This is fine, but it is copying test dependencies too. I add to myself the excludeScope option (maven.apache.org/plugins/maven-dependency-plugin/…).

What is the most pythonic way to check if an object is a number?
...
Use Number from the numbers module to test isinstance(n, Number) (available since 2.6).
>>> from numbers import Number
... from decimal import Decimal
... from fractions import Fraction
... for n in [2, 2.0, Decimal('2.0'), complex(2, 0), Fraction(2, 1)...
How do I fix a NoSuchMethodError?
...ethod signature.
In my experience, this comes up occasionally when unit testing private methods/fields, and using a TestUtilities class to extract fields for test verification. (Generally with legacy code that wasn't designed with unit testing in mind.)

Hosting Git Repository in Windows
... start the service:
cygrunsrv --start gitd
You are done. If you want to test it, here is a quick and dirty script that shows that you can push over the git protocol to your local machine:
#!/bin/bash
echo "Creating main git repo ..."
mkdir -p /git/testapp.git
cd /git/testapp.git
git init --bare...
String output: format or concat in C#?
...h just to use the same memory reference. Therefore your code doesn't truly test the difference between the two concat methods. See code in my answer below.

Check if object exists in JavaScript
...good example was fine: jsbin.com/ibeho3/2. (Sadly JSBin redirects to the latest, and people have been editing that to within an inch of its life.)

Why would you use String.Equals over ==? [duplicate]
...string with two characters "Hi", but myItem == "Hi" or "Hi" == myItem will test reference equality. The "Option Strict On" dialect of VB.NET is better in that regard. Its "=" operator tests either tests value equality or won't compile; for a reference-equality check, one uses the "Is" operator.
