Differences between git remote update and fetch?
...uation with git rebase --onto and git cherry-pick, in that both can take a range of commits to patch onto a new base commit.
I guess that as Git has evolved over the years, some functionality was (inevitably?) duplicated, perhaps sometimes as a convenience for end-users (for example, it's simpler t...
Iterate a list with indexes in Python
... the end of the second line he says he wants to use it instead of for i in range(len(name_of_list)): which is what led me to provide an example using a for instead of what was shown in the first part.

Why does Java switch on contiguous ints appear to run faster with added cases?
...
Switch - case is faster if the case values are placed in a narrow range Eg.
case 1:
case 2:
case 3:
..
..
case n:
Because, in this case the compiler can avoid performing a comparison for every case leg in the switch statement. The compiler make a jump table which contains addresses of t...
When to use std::size_t?
...
@EntangledLoops ssize_t does not have the full range of size_t. It just is the signed variant of whatever size_t would translate into. This means, that the full range of the memory is not usable with ssize_t and integer overflows could happen when depending on variables o...
Difference between numeric, float and decimal in SQL Server
...h internally stores everything as a log of base 2. That allows a the full range of precision in one field with the drawback that only the first ~8 digits will be accurate.

What does the “yield” keyword do?
...ou create a list, and so an iterable:
>>> mylist = [x*x for x in range(3)]
>>> for i in mylist:
... print(i)
0
1

Everything you can use "for... in..." on is an iterable; lists, strings, files...
These iterables are handy because you can read them as much as you wish, but y...
What's the idiomatic syntax for prepending to a short python list?
...rom collections import deque
def list_insert_0():
l = []
for i in range(20):
l.insert(0, i)
def list_slice_insert():
l = []
for i in range(20):
l[:0] = [i] # semantically same as list.insert(0, i)
def list_add():
l = []
for i in range(20):
l = ...
Can Python test the membership of multiple values in a list?
...proach is about an order of magnitude faster:
>>> smallset = set(range(10))
>>> smallsubset = set(range(5))
>>> %timeit smallset >= smallsubset
110 ns ± 0.702 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

Is 1.0 a valid output from std::generate_canonical?
...egative infinity. Since generate_canonical should generate a number in the range [0,1), and we're talking about an error where it generates 1.0 occasionally, wouldn't rounding towards zero be just as effective?
