What are the relative strengths and weaknesses of Git, Mercurial, and Bazaar? [closed]
...arge repositories with long nonlinear history (the performance improved at least for not too large repositories), the fact that default paradigm is one ranch per repository (you can set it up to share data, though), and centralized concepts (but that also from what I have heard changes).
Git is wri...
Proper stack and heap usage in C++?
... on 32-bit OS, the stack has a small and fixed (at thread-creation time at least) size (typically just a few megs. This is so that you can create lots of threads without exhausting address space. For 64-bit programs, or single threaded (Linux anyway) programs, this is not a major issue. Under 32-bit...
Where is a complete example of logging.config.dictConfig?
...
This is the more relevant / useful example, at least in my case. It was the final logging.info('Hello, log') that made things click for me. The confusion in the documentation is that with dictConfig we no longer need to perform getLogger or any of those actions.

Mean per group in a data.frame [duplicate]
...
@HermanToothrot I would say so, at least for me. In this case especially, by using .SDcols, they specified exactly which columns they want to apply the function to. If you could imagine a case in which you had a data.table with a larger number of columns, you ...

How to convert a data frame column to numeric type?
...
@MySchizoBuddy is correct, at least with my data. The original df won't take on the "converted" columns as factors; they'll remain character. If you wrap the sapply call in as.data.frame() on the right hand side, as @Mehrad Mahmoudian suggested below, it ...
Java 7 language features with Android
... as the compatibility was limited to level 6 with no way (no simple way at least) to really use java 7:
First I installed a JDK7 on a machine that had no other JDK installed - Eclipse and Android are not installed either:
Then I installed a brand new Eclipse Indigo and checked it was actually...
What does “Auto packing the repository for optimum performance” mean?
...t invokes git gc --auto. If there are enough loose objects (by default, at least 6700), it will then invoke git repack -d -l to pack them. If there are too many separate packs, it will also repack them into one.
A pack is a delta-compressed single file, containing a large number of objects. It's mo...
Why does document.querySelectorAll return a StaticNodeList rather than a real Array?
...rty of type unsigned long because they believe every implementation can at least support that, but they won't say explicitly that the [] index operator should be overloaded to support getting positional elements, because they don't want to stymie some poor little language that comes along that wants...
