URL Encoding using C#
...file name) may be constructed using Uri.EscapeDataString(fileOrFolderName) allowing all non Uri compatible character (spaces, unicode ...). For example to allow any character in filename, use: req =(FtpWebRequest)WebRequest.Create(new Uri(path + "/" + Uri.EscapeDataString(filename))); Using...
Which is faster : if (bool) or if(int)?
...s a bool as an 8-bit value, and your system ABI requires it to "promote" small (< 32-bit) integer arguments to 32-bit when pushing them onto the call stack. So to compare a bool, the compiler generates code to isolate the least significant byte of the 32-bit argument that g receives, and compares...
SQL Server: Query fast, but slow from procedure
... the quoted answer did not solve the problem for me. The query still ran really slow from a stored procedure.
I found another answer here "Parameter Sniffing", Thanks Omnibuzz. Boils down to using "local Variables" in your stored procedure queries, but read the original for more understanding, it...
How to make my custom type to work with “range-based for loops”?

auto && __range = range_expressi...

Autoreload of modules in IPython [duplicate]
Is there a way to have IPython automatically reload all changed code? Either before each line is executed in the shell or failing that when it is specifically requested to. I'm doing a lot of exploratory programming using IPython and SciPy and it's quite a pain to have to manually reload each module...
