I would say that threading for something this simple is overkill. You're better off using some form of asynchronous programming.

For me neither is better or worse, but Subversive is the default SVN plugin in Eclipse Ganymede platform, so there's a chance that it's better integrated with Eclipse. |
Proxy use can be configured in the web.config.
The system.net/defaultProxy element will let you specify whether a proxy is used by default or provide a bypass list.

Python distutils - does anyone know how to use it? |
|python|installation|linux|distutils| |
I wrote a quick program in python to add a gtk GUI to a cli program. I was wondering how I can create an installer using distutils. Since it's just a GUI frontend for a command line app it only works in *nix anyway so I'm not worried about it being cross platform.

Your question assumes that mail clients follow the RFC standards for MIME encoding, which they don't. I'd advise you collect a bunch of mail from sources and try and process it as-it-exists. The problem you are facing is extremely difficult (perhaps impossible) to solve 100%. |
We just put the EntLib 3.1 binaries in the global assembly cache and add references in our projects. We typically only use the logging framework, though. |
A google search turns up the [parsedatetime][1] library (associated with the [Chandler project][2]), which is designed to do exactly this. It's open source (Apache License) and written in Python. It seems to be quite sophisticated -- from the homepage:

Generally, it's better to have one SELECT statement. One of the main reasons to have databases is that they are fast at processing information, particularly if it is in the format of query.
If there is any drawback to this approach, it's that there are some kinds of analysis that you can't do with one big SELECT sta... |
I would say 1 query with the join. This way you need to hit the server only once. And if your tables are joined with indexes, it should be fast. |
You should run a profiling tool if you're truly worried cause it depends on many things and it can vary but as a rule its better to have fewer queries being compiled and fewer round trips to the database.
Make sure you filter things as well as you can using your where and join on clauses.

You obviously need that "messages lines" can be distinguished from "log lines"; if you allow the message part to start with date/time after a new line, then there is simply no way to determine what is part of a message and what not. So, instead of using the dot, you need an expression that allows anything that does not... |
This will only work if the log message doesn't contain a date at the beginning of the line, but you could try adding a negative look-ahead assertion for a date in the "message" group:
(?<date>\d{2}/\d{2}/\d{2})\s(?<time>\d{2}:\d{2}:\d{2},\d{3})\s(?<message>(.(?!^\d{2}/\d{2}/

Proc is older, but the semantics of return are highly counterintuitive to me (at least when I was learning the language) because:
