A day on the baltic coast

Last Sunday I have been fishing. I didn’t meet with Marco, he was busy. So I got invited to join Peter and he fetched me by car on Sunday morning. We left heading north towards the vast shores of Wagria. After one hour continuous driving we were already almost there. Just a final stop to buy another candy bar on the gas station and then it was only a few more minutes to reach the beach. We there met some more friends and had six hours of excessive fly fishing. Unfortunately no fish, though.

Altogether it was nontheless a nice day on the coast and we had plenty of fun.

When I arrived at home I expected something like “Oh where’s the fish?”. I prayed to the gods we would at least have some fish fingers in the fridge. But it was alright without fish as everyone at home knew I had a good day.

SEO fscking

Funny, today I had some interesting hits in my log, someone came from a page with an engine spying for the keywords used on my page. Now I got curious and did some research. I indeed noticed that if someone searches via google for example hp compaq 6715 b, hp compaq 6715b, et cetera I am very close behind top ranking pages of mighty HP itself. I am doing strong promotion for nothing. What a shock. Hey, come on – please give me an hp 6715 b or something comparable, I really enjoyed it a lot! So I already knew that on various topics my page has good ranking on google.com like vm workstation for linux,  vmware linux 2.6.27 or flowplayer and dvgrab. And guess what? I have no clue about SEO. And guess somewhat else. This post is simple SEO done in 5 minutes.

P.S. If anyone at HP Compaq wants his name eternally remembered – you know what do ;P

Building another fly rod part 2

Due to given circumstances I have not been able to kick off this project earlier. On the 23rd of February we had a great handwork evening at home – Sarah was tailoring next to me and I was glueing the grip and wrapping the guides onto the fly rod blank.

I bought my parts from the US and Germany. The main reason for this is plain simple. In Germany I haven’t found any dealer for the stripping guides.

  • Loop Green Line series blank  in 9′3″ and the specified line class is #6-7
  • Cork Fly Rod Grip Reverse Half Wells – supreme quality
  • Fuji Concept Stripping Guides – SiC ring in 16 and 12 /w Chrome finish
  • Struble Fly Rod Reel Seat – Standard Uplocking U-3 – Polished Alum. /Cocobolo
  • Pacific Bay Snake Guides in 2,2,2,2,3,4,5 Chrome finish
  • Pacific Bay Fly Rod Tip Top – Chrome finish / Std. loop / size 5 tube
  • Pacific Bay Aluminum Winding Check – TiCH finish / 0.342 in. I.D.

On Sunday I am going to take it with me to the coast. I am already very excited.

March 2009

Oh no, it’s already march?! Being so busy seems to quicken the days passing by. Nontheless, tomorrow my younger brother has his 29th birthday (Hey hey (: )  and today in the evening is parents’ evening in the kindergarten (first time for me). On Saturday we are going by to buy a new table, chairs and stuff for the kitchen and leaving the boys in my mums’ care. A few hours exclusive free time. And last but not least this Sunday I am finally going to have a day on the coast to test my new self built fly rod. I am going to meet there with Marco, a friend of mine.  Sarah expects me to catch at least one seatrout for dinner. Pretty much expections….

Headphones, notebooks, linux and alsa

Every day I am on the way to work I listen to music. At least usually. But not recently. A plain simple explanation is I had no proper headphones for my Vaio notebook. I gave away mine and didn’t get them back yet. So today I got my new headphones by mail. Nothing special, it’s the Koss Porta Pro. I had them before and liked them, they are affordable and sound okay. I took them and while Amarok was loading I plugged the Porta Pro in and started with…uh! The music came straight out of the PC speakers!

This seemed to be a problem with Alsa and I have found the fix for this in a flash.

Edit for example /etc/modprobe.d/alsa-base.conf and add the line

options snd-hda-intel model=vaio position_fix=0

and then at last (no need to reboot) I did as root

rmmod -f snd_hda_intel && modprobe snd_hda_intel

That solved the problem for me.

I finally confess whatever you want

Oh my god, I am now older then I once expected ever to be – please call me a 30 year old whatnot. And if someone still needs to be prodded – it’s now 2009, indeed. Currently I am doing some ugly hack to run Samba on a Vbox Linux which is hosted on Syscrash XP, where the XP shares are exclusively mounted in the Vbox offering Truecrypt containers via Samba to the outside accessible with OpenVPN. And ffs yes, the shares get rsynced periodically. Any questions? Besides I am running some gentoo vhosts in a cluster to test some skripts I wrote for making our deployments recover themselves when problems emerged and the systems went fsck. Hooray.

Debian Lenny and my Sony Vaio VGN-FZ38M Notebook

Since a few weeks now I am in a new employer-employee relationship. I got a brand new Asus notebook. By accident I indeed booted M$ V1sta and cleanly restarted the computer. I then changed the BIOS password and was already happy to reboot, to enter the password and then install Debian GNU/Linux. The password??! It didn’t accept my password! Okay, after a few calls with the Asus customer support I really was very unpleased and we had to send this piece of cake back to the trader. I really can’t recommend the Asus support. That’s my personal experience. It’s now 4 weeks back we sent it in and we still didn’t get something back. So in the short term I got another Notebook, it’s a Sony Vaio VGN-FZ38M. Everything runs fine, the installation was straight forward and I had no glitches yet.

The WLAN device required to fetch the driver from this intel page und to put it in the /var/firmware/ directory.

emil@xxx:~$ ls -l /var/firmware/
total 184
-rw-r–r– 1 root root 187672 2008-12-03 14:56 iwlwifi-4965-2.ucode

My config fle for the network devices looks similar to the lines below, we have of course an encrypted WLAN and so I had to pass some more parameters to the config.

emil@xxx:~$ cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

This works for me, the screen resolution is sometimes a handicap and I would like a better battery uptime. But altogether this seems to be a good device without anything really ugly per my definition.

For further information about linux on notebooks etc you might have a look at tuxmobil.org.

HTH, Emil

EDIT: This notebook does not support Intel Vanderpool / VT technology !

This really is a big disappointment !

A NetXMS Howto

Today I decided to do a NetXMS test installation on my root server. Why am I doing this? There’s so much other monitoring software available to perfectly fulfill this purpose. Well, why not – maybe it’s just great.

The install procedure here is done on debian etch. There might be smallish quirks for other distributions. Just ping me for help or whatever.

As ever just grab the current sources and put them somewhere you like. I copied the core files’ source code to my server and I dare say you’ll get more bandwidth here. No offense meant. *scnr*

cd /usr/src/

wget https://uruz.org/files/netxms-0.2.22.tar.gz

Extract the file and change dir to the fresh and virginal source code.

tar xvzf netxms-0.2.22.tar.gz

cd netxms-0.2.22/

Now it’s time to perform a miracle and configure the coming build process. I prefer MySQL for myself while NetXMS should work with PostgreSQL, Oracle etc. And I’d like to have NetXMS resident in /opt/

./configure –with-server –with-agent –with-mysql=/usr –prefix=/opt/netxms

make

Get a cup of tea and maybe tell your girlfriend how much you’d like to _____ her and to _____ with her on the _____ all night long, but in fact you are still too busy and have to solve this first. There’s plenty of time to relax when it’s done.

make install

Lo and behold! The server is installed!

Now copy the default netxms daemon and agent configuration file to /etc/ and edit them afterwards.

cp ./contrib/netxmsd.conf-dist /etc/netxmsd.conf

cp ./contrib/nxagentd.conf-dist /etc/nxagentd.conf

nano /etc/netxmsd.conf && nano /etc/nxagentd.conf

Next simply create the database and initialize it with the sql/dbinit_mysql.sql script.

mysql -u root -h localhost -p

mysql> create database netxms;

mysql> GRANT all ON netxms.* TO ‘netxms’@’localhost’ IDENTIFIED BY ‘password’;

mysql> \q

/opt/netxms/bin/nxdbmgr init sql/dbinit_mysql.sql

The next step is to start the netxmsd and nxagentd.

/opt/netxms/bin/netxmsd -d && /opt/netxms/bin/nxagentd -d

So when that’s done run the admin console and connect to the server to change the default password of the admin user. And if you like you could add another unprivileged user for trivial monitoring. That’s all best described in the console docs. And of course have fun playing with it, it looks promising.

It is late now at my place and I am going to bed to be fit for work tomorrow. I promise to enhance this post asap and maybe going to build a .deb file, don’t expect it to happen until I woke up or so. I’ll sleep soundly knowing NetXMS is watching over my server.

P.S. I really would enjoy a linux console, but that’s not availbile yet. *poke around*

I really miss my family

I feel so unhappy right now. The weather forecasts are all saying we are getting very bad weather this coming weekend. That means I possibly can’t go to fetch them. Life sometimes really sucks even worse than the day before. At least I am doing good progress in relocating things. And Sarah is so deliriously happy about the new apartment – I have shown her a video via the internet. Well, it’s not the time to give it up. Maybe the weather is going to surprisingly change at the weekend. I hope so.

Relocation Now!

This weekend I have been very busy with preparing our relocation to Bad Oldesloe. It feels good to know we are going to leave this way too small apartment behind. And I am so happy to finally see Sarah, Erik and Einar again.

Sad to say Sarah had a spinal disc herniation shortly after going to Nuremberg. This old apartment we are leaving behind is on the fourth floor without an elevator and so it was impossible for Sarah to come back. Thus I haven’t seen her and the boys since they left on the 18th of October. It frequently made me feel so downfallen not to have them around me.

I am relieved to know it’s almost overcome and for the next days I am going to move things from this place to our new apartment. And when that’s done I am going to pick up my family from Nuremberg and take them to our new home. And we are going to take good care of Sarah’s injury.
