You can use a range to do that.
git log master..
If you've checked out your my_experiment branch. This will compare where master is at to HEAD (the tip of my_experiment).

Why does Python use 'magic methods'?
...ted in Python. That's more a bug than a feature, though (e.g. Python 3.2's range object can mostly handle arbitrarily large ranges, but using len with them may fail. Their __len__ fails as well though, since they're implemented in C rather than Python)

What is the syntax to insert one list into another list in python?
..., 'c', 3, 4, 5]
List slicing is quite flexible as it allows to replace a range of entries in a list with a range of entries from another list:
>>> l = [1, 2, 3, 4, 5]
>>> l[2:4] = ['a', 'b', 'c'][1:3]
>>> l
[1, 2, 'b', 'c', 5]

How to initialise memory with new operator in C++?
...l. You can use STL containers to do just about anything you would do with raw memory, including allocating and initializing all in one fell swoop:
std::vector<int> myInts(100, 0); // creates a vector of 100 ints, all set to zero

Understanding how recursive functions work
...o be bigger than b, then the answer is 0 - there aren't any numbers in the range! Therefore, we'll structure our solution as follows:
If a > b, then the answer is 0.
Otherwise (a ≤ b), get the answer as follows:
Compute the sum of the integers between a + 1 and b.
Add a to get the answer.

Is MD5 still good enough to uniquely identify files?
...
Personally i think people use raw checksums (pick your method) of other objects to act as unique identifiers way too much when they really want to do is have unique identifiers. Fingerprinting an object for this use wasn't the intent and is likely to req...
uint8_t vs unsigned char
...8 bits. Both places are where space matters and we often need to look at a raw dump of the data when debugging and need to be able to quickly determine what it represents.
The first is in RF protocols, especially in narrow-band systems. In this environment we may need to pack as much information as...
