Impreza transmission death

One of my larger fears when I bought my Subaru Impreza with a CVT transmission was that the transmission would fail early, but not early enough to be covered by warranty. I saw talk online about reliability problems with the tech, which was fairly new to cars, with the Impreza only being in its second year with them I believe. On last Wednesday, my transmission did fail, but luckily it is going to work out alright, as Subaru of America (SOA) is going to help me out.

Rsync and dealing with “some files vanished” warning

I use rsync for backups, site deployments, and other purposes where I need to sync two folders. It took a little while to figure out, but has been great for those purposes since. Every once in a while, though, I run into issues with it. Recently, I set up an rsync script to back up most of the files on my entire computer. Since this takes a while and the computer is actively running during the backup, things can change while it is still running. This can lead to some errors like “rsync warning: some files vanished before they could be transferred”. Even though this is a warning, and the sync works perfectly fine, it returns a non-zero exit code. This caused my script to stop and thus the rest of the backup activity didn’t finish.

I looked for an option or simple solution to allow it to go on without complaining.

MySQL: DELETE with sub-query on same table

I had an issue with a MySQL query containing a sub-query recently where it worked fine when done as a SELECT query, but gave an error when switching it to a DELETE query. The error given was something like ‘You can’t specify target table “items” for update in FROM clause’. The sub-query was referencing the same table as the main query, which apparently can’t be done directly in MySQL because the table will be modified during deletion. But there is a sort of a hack I found in this StackOverflow answer, among others, to force it to create a temp table and allow it to work.
