Blackout in Berlin

, ,

Yesterday night, 0:30 .. everything except traffic lights was switched off.

Solved: Skype crashing / aborting on Linux

, , ,

Your Skype Linux is aborting randomly just a few seconds after connecting? (console message: skype: pcm.c:2782: snd_pcm_areas_copy: Zusicherung »src_areas« nicht erfüllt.)

Try this in your terminal:

mkdir ~/.Skype/Logs

it seems like Skype is expecting this directory and crashes when its not there.

This bug is known since at least 2011-04-14 but new Skype owner Microsoft apparently is not in a hurry to fix it.. sad

Tested with Skype 2.2.0.35

Good luck!

S Bahn Berlin refurbishes old trains from GDR times to compensate shortages

, , ,

Today I was riding a refurbished series 485 ("Coladose ") S-Bahn. These trains where made in the 1980ies and 20 of them where already sent to retirement when the S-Bahn decided to reuse them. The whole electric equipment and interior, including floors have been replaced and they where newly painted.

Use Kodak 5250 (5200 series) with Ubuntu Linux

, , ,

There is an open source driver at sourceforge which worked fine for me with Lubuntu 11.04. Download the debian package here: http://sourceforge.net/projects/cupsdriverkodak/files/c2esp_18-1_i386.deb/download
Scanning not tested yet on Ubuntu, but working with Mac OS X.

I am using the printer via Wireless. At the setup routine enter
socket://your_printers_ip:9100/
as device URI.

Use Kodak 5250 (5200 series) via Wireless on a Mac even though Kodak says its impossible..

, , , ...

When I bought my new Kodak 5250 AiO printer I expected that it would work only via USB cable since its written on the package that printing with a "PC/MAC" is only possible via USB cable (which is not included) wink

After logging the printer in to my Wireless network (which was pretty easy through the internal display) my Mac found it but failed to install a driver since it could not find any. OK, next I tried to install the Software from the CD from the package (with no USB cable connected of course) at the end it gave me the choice between "USB" and "share printer with another mac". I selected the last one.

But the printer utility could not find any printers ("connection failed"). OK back to the Mac OS native printer setup. This time it found a driver, but said the driver was incomplete. I ignored the message and proceeded.

After this the Kodak printer utility was able find the printer! It even did a successful firmware update via Wireless (I was happy when it finished though..). Also the scanner was working properly. I did a scan using the Mac's native utility.

Update
The new Kodak-Software from the Internet now recommends exactly what I did when you click on the newly added radiobutton "Wireless"..

Replace iCal / Address Book leather skin and fix other OSX 10.7 Lion annoyances

I just discovered a nice little tool which can fix several things that might annoy you after upgrading to OSX Lion. Its written by Fredrik W. You can download Lion Tweaks here. It worked fine for me but be careful since it changes system files.

Apple OSX: Mute startup sound / 'chime' in OSX 10.7 Lion and others

, , , ...

Acid got a working solution for OSX Lion which disables the startup sound without affecting your sound volume after logging in again. This was posted as a comment at the official Apple Forum originally. Thanks to Acid for this!

1. Login as administrator and open a terminal window

2. Create scriptfile for muting

sudo nano /path/to/mute-on.sh

3. Enter this as content, when done press control+O to save and control+X to exit:

#!/bin/bash

osascript -e 'set volume with output muted'

4. Create scriptfile for unmuting

sudo nano /path/to/mute-off.sh

5. Enter this as content, when done press control+O to save and control+X to exit:

#!/bin/bash

osascript -e 'set volume without output muted'

6. Make both files executable:

sudo chmod u+x /path/to/mute-on.sh

sudo chmod u+x /path/to/mute-off.sh

7. Check if any hooks already exist (these will be overwritten, so make sure it is OK for you)

sudo defaults read com.apple.loginwindow LoginHook

sudo defaults read com.apple.loginwindow LogoutHook

8. Add hooks for muting

sudo defaults write com.apple.loginwindow LogoutHook /path/to/mute-on.sh

sudo defaults write com.apple.loginwindow LoginHook /path/to/mute-off.sh


Notes:

- /path/to/ is the location of the scripts, I used /Library/Scripts/

- you can skip the unmuting loginhook (i.e. each logout will silence your machine), but I like it this way because I always have sound available exactly at the volume level I set last time

- root has to be the owner of the script files - running an editor from command line with sudo is the easiest way to achieve that (otherwise you need to chown)

- to delete the hooks, use the following:

sudo defaults delete com.apple.loginwindow LoginHook

sudo defaults delete com.apple.loginwindow LogoutHook
