Why does Python code run faster in a function?
... (LOAD_GLOBAL), which is a true dict search involving a hash and so on. Incidentally, this is why you need to specify global i if you want it to be global: if you ever assign to a variable inside a scope, the compiler will issue STORE_FASTs for its access unless you tell it not to.

Java naming convention for static final variables [duplicate]
...are fields themselves, so why should obscuring a field be something to consider? I can sort of see the point about obscuring a type name, but you can't exactly have a collision that wouldn't be handled by the IDE/compiler.

...eness it originally had so I can use it most efficiently - this might invalidate it. As in:
auto&& var = some_expression_that_may_be_rvalue_or_lvalue;
// var was initialized with either an lvalue or rvalue, but var itself
// is an lvalue because named rvalues are lvalues
use_it_elsewhere(st...
When to make a type non-movable in C++11?
I was surprised this didn't show up in my search results, I thought someone would've asked this before, given the usefulness of move semantics in C++11:

How do Mockito matchers work?
...he object matches the Matcher's criteria. They are intended to be free of side effects, and are generally used in assertions such as the one below.
/* Mockito */ verify(foo).setPowerLevel(gt(9000));
/* Hamcrest */ assertThat(foo.getPowerLevel(), is(greaterThan(9000)));
Mockito matchers exist, sepa...
Is git-svn dcommit after merging in git dangerous?
...the work branch that I want to commit to svn. This is because I want to avoid committing the three local change commits. Then, I dcommit from the master branch and rebase everything.
It is worthwhile running git svn dcommit -n first to make sure that you are about to commit exactly what you intend ...
