Why is it considered a bad practice to omit curly braces? [closed]
... ever really bit me was when I was debugging, and commented out bar():
if(foo)
// bar();
doSomethingElse();
Other than that, I tend to use:
if(foo) bar();
Which takes care of the above case.
EDIT Thanks for clarifying the question, I agree, we should not write code to the lowest common deno...
How do I expand a tuple into variadic template function's arguments?
...forward<F>(f), ::std::forward<T>(t));
}
Example usage:
void foo(int i, bool b);
std::tuple<int, bool> t = make_tuple(20, false);
void m()
{
apply(&foo, t);
}
Unfortunately GCC (4.6 at least) fails to compile this with "sorry, unimplemented: mangling overload" (which ...
How can I get query string values in JavaScript?
...eURIComponent(results[2].replace(/\+/g, ' '));

Java 8 way to sort it would be:
fooHashSet.stream()

Why must we define both == and != in C#?
...overloads the equality operator, not the inequality:
module Module1
type Foo() =
let mutable myInternalValue = 0
member this.Prop
with get () = myInternalValue
and set (value) = myInternalValue <- value
static member op_Equality (left : Foo, right : Foo) = left.Prop...
What's the difference between git clone --mirror and git clone --bare
...some remote branches (devA/master, devB/master), and some other refs (refs/foo/bar, refs/foo/baz, which might be notes, stashes, other devs' namespaces, who knows).
git clone origin-url (non-bare): You will get all of the tags copied, a local branch master (HEAD) tracking a remote branch origin/m...
How are booleans formatted in Strings in Python?
...he object as transparantly as possible for python. For example, print(str("foo")) merely prints foo on a new line. print(repr("foo")) however prints 'foo' on a new line, including the quotes, since that's what you need to type in the python interpreter to get the corresponding object to the argument...
Using Git, show all commits that are in one branch, but not the other(s)
...
Note that git log foo..bar will show the commits between bar's latest and foo's latest, but not other commits missing from further back in time. To see everything in bar but not in foo, you should use @jimmyorr's solution.

RestSharp JSON Parameter Posting
...t do
request.RequestFormat = DataFormat.Json;
request.AddBody(new { A = "foo", B = "bar" }); // uses JsonSerializer
If you just want POST params instead (which would still map to your model and is a lot more efficient since there's no serialization to JSON) do this:
request.AddParameter("A", "f...
