Typo3's multi language support is well known and working fine. However, when translating large numbers of page entries using the "Copy Default Values" feature, there is one disadvantage:

By default, typo3 adds the string "[Translate to LANGUAGE:]" to every "translated" page object. Even worse, the string "(copy)" gets prepended to every header.

Lucky us, typo3 offers a solution to this dilemma:

Just add the following to your root page TS config (page properties => Resources) and "Translate to" and "(copy)" are gone:

TCEMAIN.table.pages {
disablePrependAtCopy = 1
disableHideAtCopy = 1
}
TCEMAIN.table.tt_content {
disablePrependAtCopy = 1
disableHideAtCopy = 1
}

Vor kurzem habe ich zwei Exemplare des genialen Infrarot-Einschalters von Atric erstanden.

Der Einbau gestaltete sich dank der umfangreichen PDF Dokumentation unter Hinzuziehung des Mainboard-Handbuches mehr als einfach.

Auch die Inbetriebnahme mit lirc stellt einen vor keine größeren Hindernisse:

Man muss lediglich /etc/lirc/hardware.conf anpassen

REMOTE="Atric rev.5 IR Receiver" #optional
REMOTE_DEVICE="/dev/lirc0"
REMOTE_MODULES="lirc_serial"
START_LIRCD="true"

und ein "setserial /dev/ttyS0 uart none" an geeigneter Stelle unterbringen.

Nun noch eine passende Config von hier ziehen und als /etc/lirc/lircd.conf ablegen.

Mittels "sudo mode2 -d /dev/lirc0" kann man sich direkt die gesendeten Impulse anzeigen lassen.

"sudo irw" dekodiert die emfangenen Singale und gibt nur erkannte Befehle aus (gemäß der aktuell geladenen lircd.conf).

Die Einträge für die Felder "Frontend Layout" und "Backend Layout" lassen sich, wie alle anderen BE Felder auch, leicht über den TS-Config Editor im Bereich Resourcen der Root Page (Weltkugel) editieren:

TCEFORM.pages{
  # remove "Frontend Layout"
  layout.disabled = 1
  # optionally: remove "Backend Layout (subpages of this page)" 
  backend_layout_next_level.disabled = 1
  # rename "Backend Layout (this page only)" 
  backend_layout.label = Layout
} 

It's a known issue to everyone who ever set up an multi-boot environment using Windows and $other_OS, that Windows likes to replace the existing boot manger with its own.
Normally, you'd just boot up a rescue CD and reinstall your favorite boot loader (or that one that comes with your OS' rescue CD ).
Sadly, the Ubuntu 10.04 Alternate Desktop CD doesn't support my crypto-raid-setup. The rescue mode installer doesn't recognize my raid set up at all (even thou it gets assembled^^).
Therefore I've to repair it by hand:

After booting, the Ubuntu rescue CD offers to switch into a root terminal.

The raid was assembled automatically, so there is no need for doing it manually:

mdadm --assemble /dev/sda1 md0 

I am going to build a chroot environment in /mnt, change root into it and reinstall grub2:

At first I have to mount the crypto device for the root file system:

cryptsetup luksOpen /dev/md0 md0 
mount /dev/mapper/md0 /mnt 

Now we've to add the missing pseudo file systems:

mount -o bind /dev /mnt/dev
mount -t sysfs sys /mnt/sys
mount -t proc proc /mnt/proc

Last but not least: We must not forget to mount the boot device. In my case it is just an ordinary partition:

mount /dev/sda4 /mnt/boot

Our change root environment is ready for usage and we simply have to chroot into it:

chroot /mnt 

Now, grub2 can be easily restored:

grub-install /dev/sda

As a final step, we'll ensure that grub is up-to-date:

update-grub

To enable a typo3 backend user (or even a whole user group) to delete the typo3 cache is quite simple.
A simple entry in the user's oder the user group's TS config is sufficient:

options.clearCache.pages = 1 
options.clearCache.all = 1
