HOWTO: vsftpd's Virtual User Use Local Privileges

If you are using vsftpd with virtual users, as described in official example, and are suffering problems like this:

226 Transfer done (but failed to open directory).

(you may see above text in client or server log), you may consider using "virtual_use_local_privs".

Per study of cpdohert, if you want vsftpd's virtual user follow local privileges, you have to use:

virtual_use_local_privs=YES

FTP Ascii Mode in KDE (kioslave)

Write a ~/.kde/share/config/kio_ftprc, with

[hostname]
textmode=true

Or use [] instead of [hostname] to make it used everywhere.

Warning: this will likely mess up any transfers of binary files.

Steps to Upgrade MoinMoin Wiki from 1.5.* to 1.6.*

I've been using the MoinMoin Wiki from Debian Testing for some time and this morning I found it was upgraded from 1.5.8 to 1.6.2, and unsurprisingly, my Wiki installation stopped working, very obviously some data migration may be necessary.

After wasted some time, I found a good article: Thomas Waldmann's AnotherWayToMigrateFrom1.5To1.6. I couldn't find a good official migration guide like this, which told you that you must run cache cleaning and data migration.

Hope this is useful to other MoinMoin users.
