How to Prevent Data Loss in the Subversion Cleanup Cycle

Subversion is an open source version control system. It uses local directories and files as metadata in order to keep track of synchronizing your local copy of a project with the copy that is on the Subversion server. Sometimes these local files get “hosed” (that’s a technical term meaning really messed up). This is usually because there was a connection issue that occurred during the time that you were performing an SVN action with the server.

In such cases, the software will inform you that something went wrong and that you need to perform the Cleanup action. And in some cases, this Cleanup action also fails, leaving you with a project that can no longer commit code changes back to the server. What to do?

How to Delete Old Emails in MS Exchange Using EWS

Background

I work within a corporate environment that manages its own Microsoft Exchange Server. I am also on a development team and receive thousands of automated email messages per day from various services that run across multiple servers. I started out creating rules for these emails in MS Outlook that sorted them into folders based on the service that generated them. I would go in once a day and clean out the folders. This is a bit tedious. Additionally, I want to keep emails that are within the last day in case something goes wrong with that service and I need to reference an email that was generated. Even more tedious.

Next I thought to myself, “Why don’t I use the built-in Outlook Archive method?” That would be a great option, but my company manages our archive policies, meaning I cannot modify them.

Finally, having all other avenues closed to me, I decided to write my own utility to perform this task. I am, after all, a Software Engineer.
