Happy Birthday Human Rights!

December 10, 2007 at 11:28 (human rights, politics)

Exactly today 59 years ago the Universal Declaration of Human Rights got adopted by the United Nations General Assembly. amnesty international germany is starting it’s “Gold For Human Rights” campaign today and amnesty.org is also themed golden. The campaign is about the human rights violations in china and amnesty is trying to use the publicity of the Olympic Games in Bejing 2008 to draw more attention on this really important Topic.

I actually quite in a hurry so I have to stop here with this short teaser and hope to find more time later on to write more about it!

The Future of Reading

December 5, 2007 at 13:26 (human rights, politics)

I just found this awesome Blog entry about the future of reading. It blends several statements about the new Amazon Kindle device, Open source and the usage of books and knowledge. And if you read this you can get actually really concerned about the future of knowledge and how we are going to have access to it. We have to assure that everybody has access to all the knowledge available no matter how much money she/he has,  where this person is from and why and how she/he is going to use it. And not protecting against so called “pirates” which are “stealing” intellectual property, which should be anyway public available. So please support OpenSource and OpenAccess wherever you can!

Battery Lifetime Lenovo T61 with 7-Cell-Battery

November 21, 2007 at 16:38 (Hardware, Lenovo, Linux, Notebook, T61)

So after used my T61 for quite a while now I wanted to give a update about my experience with the battery lifetime of this laptop. In almost every review about the T61 the biggest issue was its short running time on battery. And that’s at least not totally wrong. The T61 won’t ever become a battery life wonder… But after taking proper care about the Lithium ion following the Maintenance Guide on thinkwiki.org, with the help of the nice Kernel module tp-smapi, I’ve got a maximum capacity of about 74W.

Experimenting with bleeding-edge kernel sources like kamikaze-sources and its successor zen-sources and following some tips under www.lesswatts.org leaded to an energy consumption of about 16-18Wh with WiFi and even 14Wh without. Of course you get this values only with darkened backlight (use xbacklight instead of /proc/acpi/ibm/brightness see here why).

So all this together gives me something like 3 to 3 1/2 hours of surfing and working in the Uni… of course much lesser if I compile the latest KDE :-). But I thinks that are pretty reasonable results for an laptop with this performance.

Back again!

November 19, 2007 at 20:47 (Gentoo, KDE4, Linux)

I kind of neglected my Blog in the last time. I started to study and so I had to arrange some things (trying to convince my new internet provider that it is not nice to let their customers wait more than a month for their connection…) But now everything seems pretty good: I’m surfing with 16 Mbit/s and I’m really enjoying my physics studies at the University of Potsdam.

At the moment I’m playing a little bit around with a svn-Snapshot of KDE 4 and I’m actually really impressed by the appearance of the new KDE! It’s just an awesome work which this guys from Oxygen and Plasma are doing. I couldn’t have a closer look till now, because i just got it running a few minutes ago and there are still some issues with kind “mixins” from the “old” KDE which I’m using currently as my main desktop. I have i.e. 2 Taskbars in my KDE4 at the moment, the KDE 3.5 Kicker one and the new Plasma one… kind of weired. But I try do figure this out. So I might be able to switch to a new shiny desktop environment or at least exploring the new features much more in depth. I’m also really keen on looking how Amarok 4 is evolving. So lets see if KDE4 becomes the “best KDE” ever… At least it has a realistic chance.

Yet another stupid Idea…

September 12, 2007 at 22:01 (censorship, politics)

Or better the same stupid idea over and over again from different politicians!

Franco Frattini wants to “prevent people from using or searching dangerous words like bomb, kill, genocide or terrorism.” Once such a system is set up we gonna have almost chines conditions in our “democratic” Europe! Does this people really think they can avoid terrorist attacks by censoring information, which every 17 year old wannabe revolutionizer has? We should start to think about why this “terrorists” are so angry with us. Not only fighting against the symptoms.

Disk Speed Issues Solved! (at least for me)

September 12, 2007 at 21:43 (Gentoo, Linux, Notebook, T61)

I finally found out why I had such a bad disk performance! Actually I wanted to care about this problem later, because I’m traveling at the moment and therefor I wanted to have a stable system. But it got so annoying that I decided to take the risk of breaking the system totally and so I did some more serious research. A simple hdparm -tT /dev/hda revealed the following:
Timing cached reads: 7932 MB in 1.99 seconds = 3985.16 MB/sec
Timing buffered disk reads: 8 MB in 3.02 seconds = 2.60 MB/sec

So what the heck… why only 2.6MB? And by the way, why is it hda shouldn’t it be sda for a SATA disk?

It turned out that I still had compatibility mode activated in my BIOS, so the kernel recognized the SATA disk as a old style ATA disk which apparently caused this incredible low performance. After 2 minutes of changing /etc/fstab and the boot options in GRUB the hard disk was running with nice 44 MB/s.

What do we learn out of this? Don’t blame always the operating system! Maybe it’s just a wrong BIOS option…

T61 and Linux

August 29, 2007 at 16:23 (Gentoo, Lenovo, Linux, Notebook, T61)

So after quite a bit time playing around with my T61 and Gentoo I’m really surprised that there are actually so less problems. I admit that you have to use very often bleeding edge drivers (i.e. to get sound under ALSA working), but hey thats brand new hardware!  And the  awesome documentation on the Gentoo Wiki about the T61 and ThinkWiki helped a lot to get most of the things running. I just can encourage everybody who has a Thinkpad (preferable a T61) to contribute his experiences to this  two projects in order to get a even better Linux support on this notebook. There are still some unsolved issues about suspend/hibernation, the APS, Nvidia Drivers and some other minor stuff. But nothing to big, so we can hope to get them solved in a few weeks/months.

But apparently Linux has a issue with SATA performance under x86_64 (link1, link2), which is quite annoying and I’m thinking about switching back to i386 and see how it looks there…

Welcome to Germany…

August 20, 2007 at 20:07 (politics)

Yesterday a group of about 50 persons attacked and chased through the city 8 Indians at a village fair in the town of Mügeln. Mügeln, which a small town in Saxony, german state well known for its aggression potential from right wing groups(so called “Neo-Nazis“). 14 people(8 Indians, 4 police man, 2 attackers) got hurt badly and hat to get treated in a hospital.

The major of this town said to this incident: “There are no right wing groups in our town. IF there was a right wing background it must have been people from our neighbor towns.”(netzzeitung.de german) How could somebody so ignorant? There is in almost in every little/medium/big town in Germany a group of people which carrying right wing thoughts. And if there where 50 people chasing these victims through the town there have to be at least some locals…

But this is a problem what you can find all over Germany. Right wing extremist are just accepted… as long as they just sitting around, making party and talking bullshit about “foreigners” and all this usual prejudices which you can find in almost everybody’s mind about something unusual and alien. But when they really start to act, everybody gets horrible upset (“Something like this in our nice little town… I just can’t understand why!”) and wants to do something against the brown swamp. And you will see, after a few months or days, depends on how big the incident was, everybody goes back to normal and ignores this strange, hairless guys on the neighbor table in the pub.

I’m sick of it!

After removing the ugly centrino / winodows vista / energy star stickers from my laptop, I put a irrepressible.info sticker on the back of the lit. Irrepressible.info is a Amnesty International campaign, which fights against censorship in internet, especially in blogs, chats and forums. So help to defend the Freedom Of Speech and fight against censorship!

To Do:

Use your mind! Get active!
