What is a mixin, and why are they useful?
...
This particular example could have been achieved via the functools.total_ordering() decorator, but the game here was to reinvent the wheel:
import functools
@functools.total_ordering
class Integer(object):
def __init__(self, i):

Surrogate vs. natural/business keys [closed]
...The primary key is used as a clustered index which determines the physical order of your data. In general, Integer is easy to balance since it increments sequentially and your data will append to the EOF on disk. If you use less sequential data such as text or GUID(UUID), there will be a lot more di...
What is a “thread” (really)?

...BJDIR)
You should see here the usage of the | pipe operator, defining an order only prerequisite.
Meaning that the $(OBJDIR) target should be existent (instead of more recent) in order to build the current target.
Note that I used mkdir -p. The -p flag was added compared to the example of the doc...

At the very lowest level (in the hardware), yes, ifs are expensive. In order to understand why, you have to understand how pipelines work.
The current instruction to be executed is stored in something typically called the instruction pointer (IP) or program counter (PC); these terms are synonym...
