These are the steps to get a flawless working SMARTHOST on Debian Lenny 5.04.
All you need to do is to run the exim4-conf and add some lines to /etc/exim4/passwd.client.
You do not even need to touch the template file.
In this setup Exim will deliver mail to the local inbox, if it finds a .forward file in ~ exim will deliver the mail
to the address provided in the .forward file.

"Landesmeister" C-Class Latin - DONE! |

Finally we did it!
After exactly one year and two month after I started to dance with Anna (well with the one and other missed competition),
we left the C-Class behind us, but took the title "Landesmeister Latein 2010 Sachsen-Anhalt" with us.
Currently we are looking for a new trainer to get some shiny new competitive figures and of course enhance our skills ;-)
Read about the competition here:
(We are the couple in turquoise and black... mmmh, black... well... time to get a new dress)
To see the results hit "Read more ..."

Today I released my first program for Maemo on the N900.
With www2sms you can send SMS via the webinterface of O2 without actually using the webinterface.
It's designed to easily patch in new providers. Patches are welcome :-)
Currently it will not work on Maemo, because "mechanize" for python is missing on Maemo.
Thought you can run it on any platform that runs Python and QT
Everything except the scheduling works. If someone finds a quick solution, patches are welcome.
or write to '"maemo" at "olausson.de"'

It's amazing!
 (Click image to enlarge)Now it's time to port some of my favorite CLI applications to Maemo.
The Nokia N900 with Maemo-Linux is, what I was waiting for since I started to use Linux.
Three cheers for OSS (OpenSourceSoftware).

This describes how to configure the SIP account on Maemo (on Nokia N900) to work with 1&1.
Username: {Your1und1PhoneNumber}@sip.1und1.de (add the "international area code" to your number but without the "+")
Password: {YourVoIPPassword}
"Use for telephone numbers" Selected
"User name" Leave blank
"Transport" Auto (or UDP) works both
"Outbound proxy" Leave blank
"Port" 5060
"Discover public address" Selected
"Loose routing" NOT selected
"Keep-alive mechanism" Auto
"Keep-alive period" Auto
"Autodetect STUN" Auto (or stun.1und1.de)
- Here are some additional information:
realm: 1und1.de
STUN-Server: stun.1und1.de
Sip-Server: sip.1und1.de
Ports (UDP): 5070 - 5079 and 30000-30019

Some things i came across when I was setting up a new Linux KVM host:
- Which scheduler on the host ist the one to go for?
I was playing around with the available schedulers but thankfully someone else did that before.
See Bugreport #505695 on the RedHat Bugzilla.
So apparently the best suited scheduler for a KVM host is the "deadline" scheduler.
- Which scheduler on the VM ist the on to go for?
It states, that with the "noop" scheduler, the host is able to optimize the I/O request, which is what we want.
Further, the RedHat Bugreport #505695 suggest to "put virtio-blk devices in rotational mode". At least I couldn't find a kernel parameter to enable this at boot time (if someone knows, please let me know),
so this has to be done on every VM by hand (or add the following to a start script like /etc/conf.d/local.start):
# for device in /sys/block/vd*/queue/rotational ; do echo "1" > ${device} ; done
The VMs should be started without a "drive cache". For "qemu-kvm" start the VMs with
# -drive cache=off
And don't forget to enable "KSM" for page merging in Kernel 2.6.32 and later. Why? See here.

Advertisement can, but must not, be annoying |
|

Many Sites use advertisement to get some revenue for the service they provide.
So far this is not bad at all.
If I like the site and the advertising is not to intrusive I tend to click here and there on a banner/link to support the site.
But many sites have those annoying blinking, flickering, shouting, music playing, and and and Ads I can't stand.
Thought I am using Opera, there is noting like " Adblock Plus" for Firefox. Okay, Opera has a build in Ad filter, but manually adding every banner is a lifetime job. Thankfully there are two Sites (I know) which collect hostnames/IPs of servers known to host banner and other advertising stuff.
One system-wide solution would be, to add those servers to the hostfile and redirect the DNS request.
This can easily done (at least on Linux) with a ready to use script on http://hostsfile.mine.nu/.
Another approach I describe here here, is to use the urlfilter.ini file in Opera.
Just download a recent list in Opera "urlfilter.ini" format from http://hostsfile.mine.nu/ and replace the existing one in your Opera directory. To automate this and stay up to date I hacked this little python script together.
It will fetch the list, merge it with existing entries in the urlfilter.ini file and save the new list. You can enter patterns which should be removed from the list.
Just run the script (via cron) weekly and surfing the web is fun again.
From time to time you should check the file cause currently my script only merges in new lines, but does not remove hosts which have been removed from the adserver list.
(It might do in the next version)

I made it a bit more intelligent.
- can distinguish between MD/Mini and Minimization only output.
- switched from fixed column formating to white spaced formating
New version:

And finally I found one...
To all those scanner seeking Linux users:
It's supported via the sane epkowa backend.
One drawback:
The buttons are not working and for now I had no time to look into this, but a working "copy" Button would be nice :-)

YOUR BATTERY IS EMPTY - NAG |
|

You know what pisses me really off?
A mobile phone with such a crappy, intrusive, annoying and energy wasting firmware like the one in the Samsung X820.
I am talking about the useless "Your battery is empty" notification.
My phone is set to vibrate in 99.9% of the time cause I don't want it to be a pain in my neck.
(Despite the fact, that the "vibrator" is way to intense and loud it is still better than any sound)
But what happens when your battery starts to loose power?
No, the phone does not silently die, it vibrates for 1 3 second every ~10 5 minutes for 2 hours!
It could run a few hours longer, if it wouldn't try to tell me it is "empty", which it obviously is not, in the described way!
I guess you can imaging many circumstances where this "FEATURE" is more, much more annoying than a dead phone!
Is it so hard to give the user control over it's phone and let him choose on which events he will be notified?
I guess not.
So if any mobile-phone-fimware-developer is reading that:
PLEASE GIVE THE USER THE POSSIBILITY TO CONTROL ALL "NOTIFICATIONS"
