Why do loggers recommend using a logger per class?

How does a hash table work?
... strings. So accessing a large array using an index is significantly much faster than accessing sequentially.
As Simon has mentioned which I believe to be very important is that the hashing part is to transform a large space (of arbitrary length, usually strings, etc) and mapping it to a small spa...
Git push won't do anything (everything up-to-date)
...t push':
master pushes to master (up to date)
quux pushes to quux (fast forwardable)
Q. But I could push to master without worrying about all this!
When you git clone, by default it sets up your local master branch to push to the remote's master branch (locally referred to as origin/maste...
Does a foreign key automatically create an index?
... search the big orders table. Now if there is an index, the search will be fast; if there is not, the search will be slow.
So in this case, the slow delete could be explained by the absence of an index. Especially if Sql Server would have to search 15 big tables without an index.
P.S. If the forei...

UINavigationController “back button” custom text?
...roblem described by @JamesBoutcher above is unnoticeable for me due to the fast initial speed of the animation. In fact, I just realized that the problem I face is especially noticeable due to slow ending animation which is when this problem is prominent.

Is there a Python equivalent of the C# null-coalescing operator?
...duce implementation is unacceptably slow, the multi-line for/if version is fastest, and the next implementation is very slightly behind. The next version is the best overall when considering simplicity and conciseness.

Linking R and Julia?
Julia looks very promising for fast and syntax-sane computation (e.g. here ), but I suspect it will not be anywhere near R in terms of overall statistics workflow for some time yet. So I'd like to use it where C++ is mainly used in R programs: to optimize slow portions of code. Before I invest th...
