Convert a Scala list to a tuple?
... I know of, but it's easy enough to make your own, e.g. case class Vec3[A](_1: A, _2: A, _3: A)

Using generic std::function objects with member functions in one class
...int)> f = std::bind(&Foo::doSomethingArgs, this, std::placeholders::_1, std::placeholders::_2);
Or, if your compiler supports C++11 lambdas:
std::function<void(int,int)> f = [=](int a, int b) {
this->doSomethingArgs(a, b);
}
(I don't have a C++11 capable compiler at hand rig...
Python string class like StringBuilder in C#?
...st of length-one strings. (To make this from a string, you'd call list(your_string). You could also use a UserString.MutableString for this.
(c)StringIO.StringIO is useful for things that would otherwise take a file, but less so for general string building.

...storyOfPresentIllness and when i write the sql, I want to name it history_of_present_illness . Is there a keyboard shortcut to switch from one to the other when I have the phrase highlighted? Or perhaps a plugin that can do this?

The _* type annotation is covered in "4.6.2 Repeated Parameters" of the SLS.
The last value parameter of a parameter section may be suffixed by “*”, e.g. (..., x:T *). The type of such a repeated parameter inside th...
Iterating through a JSON object
...
Your loading of the JSON data is a little fragile. Instead of:
json_raw= raw.readlines()
json_object = json.loads(json_raw[0])
you should really just do:
json_object = json.load(raw)
You shouldn't think of what you get as a "JSON object". What you have is a list. The list contains two d...
List goals/targets in GNU make that contain variables in their definition
...ion would be to create a trivial makefile, dummy.mk, with these contents:
__all_targets__: ; #no-op
Now invoke make as make -p -f Makefile -f dummy.mk __all_targets__. On any substantial build, the difference in the amount of output generated by make is significant. For example:
$ gmake -pn | ...
std::enable_if to conditionally compile a member function
...rying to get a simple example to work to understand how to use std::enable_if . After I read this answer , I thought it shouldn't be too hard to come up with a simple example. I want to use std::enable_if to choose between two member-functions and allow only one of them to be used.
