poor man’s TimeMachine backup

falko — Wed, 07 Jan 2009 13:02:54 +0000

If you don’t have MacOS X 10.5 (Leopard) but as well starving for a nice and easy backup then try this shell script. MacOS X provides some simple command line tools for doing a convinient backup out of the box. I wrote a little shell script which sports RSYNC to do regular backups and even archive deleted files for a certain time.

Simply modify your source and destination folder in this script and call it regularly. This can be done with cron. Your contrab entry should look something like this:

0 */2 * * * /Users/youraccount/pmt.sh > /dev/null 2>&1

This will start the script every full 2 hours. Should be sufficient.

Mail to Things Script

falko — Mon, 10 Nov 2008 08:22:40 +0000

I used to send me eMails with Tasks when I’m on the run. OmniFocus is able to fetch these Mails automatically into it’s Inbox. But not so Things. I always missed this feature and looked around for a possible Solution.

Now I found one in the CulturedCode Wiki to Things. They provide an AppleScript to do exactly this. You just have to create a rule in Mail.app to filter the eMails you want to send to Things and execute the script. Things must be running to work.

Time Machine annoyances

falko — Tue, 07 Oct 2008 14:56:38 +0000

Last weekend I reinstalled MacOS X Leopard on my MacBook Pro for it had some strange errors I couldn’t get rid of. Of course I did a Time Machine backups ahead to have my data safe during reinstallation. I didn’t chose to restore my personal account from a Time Machine backup during the installation as I wanted a clean and fresh system with all programs and settings setup up new and manually. This time I selected to create FileVault user account. This means my home folder is actually an encrypted image file. This image file will be descrypted and mounted as my home directory during login and gets automatically closed and encrypted when I log out.

This worked very well for the first hours. But then during manual installation of some programs and copying my backed up files a kernel panic occured with the grey screen of death. That’s the last thing you wanna see when you have a mounted encrypted image.

After reboot I still was able to login and everything looked OK. But my keychain was damaged. This wasn’t a big problem for the moment as there where only a few apps which made entries there. I repaired the broken keychain and everything was OK.

Then, after finishing my restore I tried to delete the old Time Machine backups from my external disks. This isn’t as easy as it seems. Just dragging it into the Trash bin and empty the Trash will take hours as the Backup consists of million of files. I tried that before….

This time I tried to delete the Backups.backupdb folder from the disk with simple Unix commands (rm -rf ). But this doesn’t work firsthand. Even as superuser I wasn’t able to delete the files. Always got a “no permission” error message. I then checked the usual suspects mds (Spotlight Metadata Service) and hidden file attributes (xattribs). But that didn’t helped.

Finally I connected the disk to another MacBook with the old Tiger 10.4 MacOS X and tried to erase the files over there. This worked well. So Tiger doesn’t care about special settings of these files and did it’s job.

After that I tried to start a fresh and clean backup with Time Machine again. But Time Machine told me that it couldn’t do a backup of a FileVault secured home folder while the user is logged in. This is logical but sad. As this is a laptop computer and I’m the only user I’m almost always logged in when this machine is on. And to extra log off to have a backup done is not really practical. So I decided to kick FileVault for a convinient Time Machine backup. This took a lot of space on my hard disk during the unencryption and about 2 hours.

But now everything is fresh and clean and even PictureSync is working properly again.

still using Quicksilver and Visor

falko — Fri, 12 Sep 2008 07:28:57 +0000

I’m still using Quicksilver as universal control instance. It has some nice features I was missing in LaunchBar. So I can change my network location profile with Quicksilver easily. It’s accessible under it’s name. I also managed to tell Quicksilver to offer .jar files as applications so I can launch them via Quicksilver. I didn’t manage to get this with LaunchBar either.

I’m also sticking with Visor the Quake style Terminal. I had some problems starting Terminal in the beginning. A SIMBL error was raised but Visor worked properly after confirming this error message. Now I found out how to avoid this message by disabling Quartz background animations in the Visor preferences.

eye candy for geeks – Visor and Nocturne

falko — Thu, 21 Aug 2008 13:07:20 +0000

Today I switched from LaunchBar back to QuickSilver. While crawling the Blacktree website I found some other interesting stuff.

First thing is Visor – an extension for the Terminal.app which offers a so called Quake-style Terminal window. When installed, Visor offers a global keyboard shortcut which opens a Terminal window. The Terminal window will slide in from the top of the screen. Another hot key stroke will hide this Terminal window again.

The second application from Blacktree is Nocturne. This will change your screen colors to a black/white screen for simulating kind of night vision:

The switch from day to night mode can be done automatically by sense of the light sensors of the MacBook Pros.

Online with Vodafone Websession

falko — Mon, 21 Jul 2008 07:39:23 +0000

If you need an temporary internet connection on the run and don’t have a special data rate on your mobile contract then maybe the Vodafone Websession is what you need.

This is a special mobile accesss point for session based internet connections. You will be charged on you normal telephon bill our via websession voucher. All you need is some special settings for the connection

You can choose to get 30 minutes, 1 hour our 24 hour session. For the 30 minutes session you’ll pay 1,95 EUR which isn’t quite cheap. But if you don’t have any data rate booked on your contract you’ll surely pay about 20 EUR per 1 MByte!!!

Normaly Vodafone is selling the Websession package with special UMTS/3G hardware like an USB-Stick or 3G ExpressCard. But if you got a mobile phone with an UMTS/3G modem which is recognized by your computer you’re all done. All you need is set up some special connection settings

Here are the “secret” settings:

APN: event.vodafone.de
username: my_username
password: mypassword
telephone number: *99***1#

getting rid of old Time Maschine backups

falko — Fri, 16 May 2008 19:15:46 +0000

If your Time Maschine backup volumes filles up you may get a warning message from Time Maschine. It tells you that Time Maschine has deleted the oldest backup set to gain enough space for the actual backup. You can acknowledge the message and even opt to not see it in the future. Time Maschine will then automatically remove oldest backups when needed.

But the deletion of old backups will take some extra time on almost every backup. So maybe you wanna get rid of some old backups manually. This can easily be achieved by starting Time Maschine, navigating to the backup you want to delete and selecting the little gear icon in the Finder. There is an option “Delete Backup”. This will remove this point in time of your backup after asking for your authorization.

If you removed a couple of backup sets to be removed Time Maschine will need some time to wipe all the files. You will see a progress window like when flushing the trash can.
After the clean up you should have enough space for your next couple of backups. You should not delete any files or folders from the backup volume by your self. Time Maschine is doing an intelligent sparse backup. If you delete files or folders manually you may destroy the consistency of your backup and thus make it useless.

Recent Stack im Dock

marcus — Fri, 18 Apr 2008 15:14:33 +0000

Heut habe ich eine tolle neue Funktion für die Stacks gefunden, welche nur über die Kommandozeile verfügbar ist, nämlich die Recent Stacks. Hier kann man sich die zuletzt benutzten Programme, Dokumente, Server etc. anzeigen lassen. Einfach

defaults write com.apple.dock persistent-others -array-add '{ "tile-data" = { "list-type" = 1; }; "tile-type" = "recents-tile"; }'

im Terminal ausführen und dann

killall Dock

zum neustarten des Docks. Voilà

Mit der rechten Taste auf den neuen Stack kann man dann die verschiedenen Typen auswählen.
Zum anpassen des Stacks kann man noch

defaults write com.apple.recentitems ABC -dict MaxAmount nn

ausführen, wobei man ABC durch Application oder Documents ersetzten kann und nn durch eine beliebe Zahl.
