What's the most efficient way to erase duplicates and sort a vector?
...
I think your results are wrong. In my tests the more duplicated elements the faster vector (comparative) is, actually scales the other way around. Did you compile with optimizations on and runtime checks off?. On my side vector is always faster, up to 100x depending on the...
How to “comment-out” (add comment) in a batch/cmd?
...ten in Bourne shell, not Windows batch, so how is it relevant here? Furthermore, the colon command being valid Bourne syntax is not a "bonus side effect"; it's precisely why it's used in that Bourne script. It's used in favor of # for comments because #, evidently, might not be a valid comment desig...
Using getopts to process long and short command line options
...de that yourself as an additional case.
So while it is possible to write more code to work around the lack of support for long options, this is a lot more work and partially defeats the purpose of using a getopt parser to simplify your code.

Difference between malloc and calloc?
... doesn't need to write them in user-space. This is how normal malloc gets more pages from the OS as well; calloc just takes advantage of the OS's guarantee.
This means calloc memory can still be "clean" and lazily-allocated, and copy-on-write mapped to a system-wide shared physical page of zeros. ...

LINQ .Any VS .Exists - What's the difference?
...similar to Any.
In short, the methods are essentially the same. One is more general than the other.
Any also has an overload which takes no parameters and simply looks for any item in the enumerable.
Exists has no such overload.

What to do about a 11000 lines C++ source file?
...le permanently, perhaps by renaming it in each branch. It's not "main" any more, it's "main for configuration X". OK, so you lose the ability to apply the same change to multiple branches by merging, but this is in any case the core of code where merging doesn't work very well. If you're having to m...

How do I parse an ISO 8601-formatted date?
... 0)
Note that dateutil.parser.isoparse is presumably stricter than the more hacky dateutil.parser.parse, but both of them are quite forgiving and will attempt to interpret the string that you pass in. If you want to eliminate the possibility of any misreads, you need to use something stricter th...
