  • Rudimentary IL dissembler for use within FSI.

    got distracted and decided I wanted to be able to 'disassemble' a function inside of FSI, much like you can do in many Lisps, this isnt very complete and I think it will only work on the most basic functions, but it was very challenging to get working so I thought I would paste it.

  • streams, memoization, suspension

    translation of http://www.cs.cmu.edu/~rwh/introsml/techniques/memoization.htm , no particular reason, just satisfying a tangent, read the cmu site for comments & insights.

  • tcpStream abstraction

    Basic (but experimental) TCP stream wrappers to help make TCP more abstracted and cleaner. Giving the user just the impression of a 'stream' that one connects to and sends and receives. This helps promote composition. The first abstraction is 'stream', really just wrapping .NET stream functions so that read returns the read n bytes and write returns the stream, all functions take NetworkStream as the first parameters, followed by other parameters. Currently we don't care about timeouts, exceptions, or other nasty's.

  • log parsing.

    basically an extension of http://msdn.microsoft.com/en-us/magazine/gg983490.aspx I can't remember why I wrote it now, it should be more generic than MSDN's version.

  • Affine Cipher

    simple affineCipher translated from https://github.com/asweigart/codebreaker/blob/master/affineCipher.py not sure if actually correct. I updated the below to make it easier to understand because I was bored, made some more changes, now pass in lambda as function to pxn instead of individual functions, as suggested by rwbarton for my haskell version.

  • Csv + Registry

    Had a C tool to parse a csv of queries and check registry against query, then spit out the result, was horrible to parse and model the data in C (just too much code) so I have converted it to F#.

  • Unmanaged memory search

    Useful for pinvoke stuff where your native API requires that you have a unmanaged buffer containing the data you want to work on. Edit: Changed native calls, removed Marshal.Copy (there is a async corner case but I won't delve into it here) and replaced with pinning.
