Log File Roller For Microsoft Windows 
Thu, Dec 11th 2008 8:50a Johan Känngård
A simple log file roller, that rolls a file from FILENAME.0, to FILENAME.1, onwards to FILENAME.9. If FILENAME.9 exists, it is deleted. Can be used to keep log files small and managable, and delete old ones. The code is not pretty, I could not get it work with loops. If anyone has a better way of doing this, please let me know! :-)
Usage:
rollLog LOGDIRECTORY LOGFILENAME
For instance, if you have a log at c:\log\at.log, you can run:
rollLog c:\logs at.log
Afterwards, you have one fi [read] Keywords: microsoft

HOWTO Restart shoutcast if inbound stream is lost
Tue, Oct 21st 2008 10:52a Johan Känngård
This is a simple way to get Shoutcast restarted (tested in Ubuntu 8.04) if the inbound stream is lost.
Put in file shoutcast_supervisor.sh in /usr/bin:
#!/bin/bash
ONLINE=$(lynx -dump localhost:8000 | grep "Stream is up" | wc -l)
if [ "$ONLINE" -eq "0" ]
then
logger -i Inbound connection not found. Restarting Shoutcast.
/etc/init.d/shoutcast restart
fi
Change ownership and group:
$ sudo chown root /usr/bin/shoutcast_supervisor.sh
$ sudo chgrp root /usr/bin/shoutcast_supervisor [read] Keywords: ubuntu |

HOWTO Edit your crontab with Emacs 
Tue, Oct 14th 2008 10:51a Johan Känngård
Another “wee” tip. I had a hard time doing this right…
Put emacs in the EDITOR shell variable:
$ EDITOR=emacs
$ export EDITOR
and add the following to your ~/.emacs:
(set 'temporary-file-directory "/tmp")
Now, edit the crontab file via:
$ crontab -e
Edit and save the file, and you should get a response from crontab:
crontab: installing new crontab
If you get an error message, something is wrong. You can check that your edits really changed your crontab [read] Keywords: |

Simple Combobox using Autocompleter.Local from Script.aculo.us 
Wed, Oct 8th 2008 9:51a Johan Känngård
The Autocompleter.Local in the Script.aculo.us Prototype-addon is quite nice. It can be used to get type-ahead into a field if you have a local JavaScript Array. I wanted to extend the functionality to have it behave as a Combobox, which is like a Select with a text input field. Here is how I did it, be advised it has some bugs, let me know if you have a better solution!

HOWTO Use Lotus Notes, Domino Designer and Domino Administrator 8.01 on Ubuntu 8.04 via Wine 1.0.0
Mon, Sep 1st 2008 4:09p Johan Känngård
I just followed Julian’s excellent guide and it worked! Even though the guide was for previous versions of both Notes, Ubuntu and Wine, I did not have to make any additional steps to get it working. All programs works, I haven’t found anything that is broken (yet), and it’s great having the Designer “directly” in Ubuntu instead of firing up VirtualBox.
Thanks Julian, for your excellent guide! [read] Keywords: designer

HOWTO: Install Shoutcast 1.9.8 on Ubuntu 8.0.4
Tue, Jul 22nd 2008 9:31a Johan Känngård
If you want to stream your own radio station, Shoutcast is an easy solution. This little HOWTO focus only on the server part, and not on the actual audio/feeding client part. I recommend reading ShoutCast Streaming for beginners and Streaming radio with ShoutCast and WinAmp to get the hang of the audio part.
Install
Download the tarball from shoutcast.com.
$ tar -xvf sc_serv_1.9.8_Linux.tar.gz
$ sudo cp sc_serv_1.9.8_Linux/sc_serv /usr/sbin
