Installing NTP daemon

Network Time Protocol can help you keeping your computers time accurate. This is important to maintain correct timestamps in log files. Not to mention how annoying it is with a clock not showing the correct time… Installing a basic NTP server will help your computer to have its time accurately controlled by NTP. The beauty of this is that when your computers time is wrong, NTP will speed up/down your clock to catch up. This is done so that cron and other time dependent tools will not notice anything.

Adding package archive for KDE

Since I’m still running Lucid Lynx, updates for KDE is lagging behind a bit. To keep a bit more up to date with existing KDE updates, I’m adding a PPA found on Launchpad, to /etc/apt/sources.list:

# KDE updates
deb http://ppa.launchpad.net/kubuntu-ppa/ppa/ubuntu lucid main
deb-src http://ppa.launchpad.net/kubuntu-ppa/ppa/ubuntu lucid main

Update the package index:

apt-get update

How to change time of cron.daily?

I’ve scoured different Linux forums for the answer to this onequestion. One of many answers is that this can’t/shouldn’t be done, because this crontab is to be executed after a computer has been booted and not at a specific time.

But what if I keep my computer on 24/7, and the time of cron.daily disturbs my work because disk intensive task are run at inconvenient times, instead of when I’m not in front of the computer. For me, the important thing is that cron.daily is executed once a day, and not x minutes after booting.

Syncing Google calendar with Kontact (KOrganizer)

There are two ways I’ve managed to do this:

1) The first one is by adding an .ICS cal to your calendars. This will result in a Read-Only calendar, which might be okay if you’re ok with adding all your appointments from your mobile phone. If this solution actually was stable, it could be enough in some instances. Unfortunately Kontact gives me regular warning messages that the calendar is not accessible. Therefore I wouldn’t recommend this approach at all.

Basically you need to login to your Google account and activate sharing of your calendar. Once you know the URL to use, this information can be entered in Kontact. After this sharing of the calendar can be disabled.

New server hardware

I’ve just finished transferring the homepage to my new server.

ASUS at5nm10i

ASUS at5nm10i

 

The new hardware is basically a fanless ASUS AT5NM10-I. The mainboard is equipped with dual core Atom CPU’s and 2GB of RAM. The passive cooling makes this computer absolutely quiet. The computer case Morex 5689 is also fanless and have grating on all sides for ventilation. The PSU is an external AC/DC converter, delivering 12 Volts to the mainboard. This solution leaves any heat that normal PSU’s generates outside of the case. The case is mounted to the wall inside a cupboard. A mount plate is included to ease the installation to vertical or horizontal surfaces.
