Apache WebDAV setup compatible with Windows

Windows supports mounting WebDAV shares as drives. WebDAV is a HTTP protocol for file access used by for example SharePoint.

Antivirus performance test

This performance test of different antivirus applications is actually a good read. There are some difference between the worst and the best. I was especially surprised to see that the antivirus software could make a simple file copy take up to twice as long. So maybe disabling the antivirus now and then isn’t a bad idea.
