Onlinetvrecorder disabled the good old RSS where I can get the list of my torrents of recorded movies. Unfortunatelly the new RSS link requires a session cookie what is not so easy with a bash script. Here is a small solution how to enable the automatic download of the RSS stream in order to download the feeds automatically.

First get an session cookie for www.onlinetvrecorder.com and store it into a local file.

wget \
    --save-cookies ~/.cookies/onlinetvrecorder \
    --keep-session-cookies \
    --post-data "email=name%40provider.com&pass=whatever&checkbox_remember=checkbox_remember&btn_login=Login&do=login" \
    -O - \
    http://www.onlinetvrecorder.com/index.php \
    > /dev/null

With this command you store the onlinetvrecorder session key to a file what you can use later on to download the RSS feed. “keep-session-cookies” are important because the key is only valid in the session. Replace “name”, “provider.com”  and “whatever” with your personal data. the “%40″ is url code for @.

wget -o /dev/null -O - --load-cookies ~/.cookies/onlinetvrecorder "http://www.onlinetvrecorder.com/rss/rss.php?hash=hashcode&userid=id"

Also replace “hashcode” and “id” with your personal data. You can see it in the browser when you check the RSS feed in your browser. Thats all. I think the uTorrent or other trackers can deal with a local file to parse. So just use a cronjob to store this file from time to time to local disc and let uTorrent do the rest.

Today I found a lot of time working on my Atmel project. My colleague Angel pointed me to the AVR USB lib project (link). Really great and makes the use of USB as easy as the good old RS232. In fact I found it even easier to deal now with USB then RS232. And hey you get 5V for free.

I started with the PowerSwitch project. Nice little USB interface to control 8 digital outputs (for switching on or off whatever you like). Its a nice Project to get started with the lib.

For programming the Atmel I used my USBProg programmer from Embedded Project. With the SPI its really great to plash the Atmel inside your circuit. Be aware that the Pins are a little bit different than in the description. In order to flash the code to my atmega8 I used avrdude:

avrdude -c avrispv2 -P usb -p  atmega8 -B8 -U flash:w:main.hex:i

The B8 parameter is very important otherwise the Atmega8 is not recognized. When you use the Atmega8 instead of the micro controller mentioned in the documentation you have to take care to use the right pins on the Atmel (it costs me 1 hour of searching for a wire error before I thought of that. )

The changes for the ISP Connector are:

• Pin 10 from the ISP connection is not connected as described to TXD instead its connected to PIN 8 and 22 as beeing the GND.
• Pin 4,6 and 8 from the ISP connection are not connected at all

The changes on the Atmel itself are:

• XTAL
  • 4->9
  • 5->10
• GND
  • 10 ->8,22
• AIN
  • 12->14
  • 13->15

The fuses can me flashed with:

or checked with

sudo avrdude -c avrispv2 -P usb -p atmega8 -B8 -U hfuse:r:hfuse.hex:b

sudo avrdude -c avrispv2 -P usb -p atmega8 -B8 -U lfuse:r:lfuse.hex:b

After that the PowerSwitch worked great!

./powerSwitch on 0 2

Today we went to the beautiful zoo in Stuttgart called Wilhelma. Was great to see guys and specially the Aquariums. If you ever visit Stuttgart the Wilhelma is a must! Here are some impressions. More are on my flickr account.

And here is the counter:

As in good old times when its raining outside, it Sunday and you definitely don’t want to clean apartment (ok at this time it was my room at parents place). There is a nice web2.0 side for making MixedTapes.

Here is the one I god from @adventskalender (nice twitter agent): christmas-favorites

And as all great Web2.0 applications you can embed it into your own blog.

Wow, its xmas time. Here is what I really really want.

After all this technical blabla I think its time to talk also a little bit on music, wah?

Couple of days ago I heard on my favorite radio station Funkhaus Europa the “La Dolce Vita” show. If you are interested here is the link to listen again and here is the link to listen live to Funkhaus Europa. What gets my attention on this show was the song “Si j’etais un homme” from “S Petit Nico”. Unfortunatelly I can not order the CD on Amazon. But I found the myspace page from “S Petit Nico” where you can listen to the song among others. Furthermore I found the music video on youtube:

Enjoy.

IBMLab just released a new Video. Well, Nic looks like a rapper on the screenshot…..

I am soooo sorry…

1. ssh -X server #as normal user
2. xterm #for testing if export display as normal user works
3. echo $DISPLAY #write it down
4. xauth #enters the shell of xauth
   1. list # find the line with the display number from step 3 for me it was “wpsvm054/unix:12 MIT-MAGIC-COOKIE-1 071df2e12cfff0ed75fd0af5869665f7″ remember the first part of it
   2. quit #to leave the shell
5. xauth extract filename system/unix:12 # the line from step 4.1
6. sudo su - # to become root
7. xauth merge filename # filename from step 5
8. export DISPLAY=:nummer.0 #Displaynumber from step 3 resp. 4.1
9. xterm #for testing

Hope it works on other systems too.

Lets find some slides on Microblogging, some videos and some examples. When I tell people about microblogging (or as some people call it “twitter“) they look at me like “what a freak!”. But let me try to explain why microblogging is realy something new and different from chat, blogs or SMS. First of all lets have a look on Slideshare what presentations are available on this topic.

Last weekend on the Barcamp in Stuttgart (#bc0711) I learned more about OpenStreetMap. Extreme impressing! What I really liked was the tremendous power of communities. Peter gave a very good presentation on Openstreetmap.

Starting today with the “Otherinbox“. Nice combination of instant email service and web emailer. If you subscribe to the service you get a domain like ansi.otherinbox.com where you can use several email addresses like facebook@ansi.otherinbox.com or intershop@ansi.otherinbox.com. The service accepts all emails for this domain and shows them in a web based mailer in seperate folders. Nice and usefull. At the moment they are in closed beta but you can follow them on twitter at @otherinbox.

Nice feature is to add Text on a picture like a watermark:

convert -font \
/var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType/luximri.ttf \
-pointsize 160 -fill black -draw "text 0,590 'Text auf Spike'" \
P1020049.JPG spike.jpg

or make a border arround a picture

convert -border 10x10 -bordercolor "#000000" P1020049.JPG spike2.jpg

Nothing special but was nice to play with it.

#!/bin/bash
rm a.csv
rm a.kml
rm a.gpx
for i in *.loc
do
gpsbabel -i geo -f $i -o csv,prefer_shortnames -F $i.csv
cat  $i.csv >> a.csv
rm  $i.csv
done
gpsbabel -i csv -f a.csv -o kml -F a.kml
gpsbabel -i csv -f a.csv -o gpx -F a.gpx

sudo gpsbabel -i gpx -f a.gpx -o garmin -F usb:0
sudo gpsbabel -i garmin,power_off -f usb:0

This script converts all the *.loc files in one folder into one GPX and one KML file. the KML file can be placed on a webserver and then fiewed with google maps or via google earth. Here are some usefull commands:

Upload route:

sudo gpsbabel -r -i garmin -f usb:0 -o kml -F u.kml

Tracks downloaden from Garmin:

sudo gpsbabel -t -i garmin -f usb:0 -o gpx -F tracks.gpx

Switch the Garmin off:sudo gpsbabel -i garmin,power_off -f usb:0

Best Webpage I found for creating routes for bike tours is Marengo

And now have fun.

Twitter has a cool API wich we can use legally. The xml list of users you follow can be retrieved with

http://twitter.com/statuses/friends/USERNAME.xml?lite=true&page=1..n (for me its ansi)

Having at the moment 112 user I follow (yesterday more then 160. ) page 1 and 2 are all my guys.

This small xsl stylesheet extracts the userids. (if anyone is into xsl please help me here. Would be great to extract username, realname and user with comma separated per line. Please add comments if you know the solution, I appreciate it!)

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
 <xsl:strip-space elements="*"/>

 <xsl:template match="/users/user">
     <xsl:for-each select="id">
      <xsl:value-of select="." />
      <xsl:text>&#10;</xsl:text>
     </xsl:for-each>
 </xsl:template>

Save this code snip to a file called extractIDs.xslt and call it with the processor:

xsltproc extractIDs.xslt friendsPage1.xml  | sed 1d >list_of_ids.txt

xsltproc extractIDs.xslt friendsPage2.xml  | sed 1d >>list_of_ids.txt

So now next step howto get the rss feeds out of it. The API offers this call

http://twitter.com/statuses/user_timeline/USERID.atom

Short bashscript like

 for i in `cat list_of_ids.txt`

 do

  echo "http://twitter.com/statuses/user_timeline/$i.atom" >>list_of_rrs_feeds.txt

 done

is doing the job. So we end up with a text file each line with one RSS feed. I totally agree its much easier at the moment to call the “user and friend” rss feed from twitter but the idea behind this is to get a list of each user so future systems can really be distributed among many microblogging systems.

apt-get install postfix

or choose dpkg-reconfigure postfix when you allready installed postfix before.

The configuration working for me is “satelite”.

1. System Mail Name: your maildomain name (interblc.com) not the dns name of your server.
2. SMTP relay host:smtp.1und1.de
3. Root and Postmaster mail recipient: your user account or external email address
4. Other destinations to accept mail for: your servername, localhost.localdomain,localhost
5. Force synchronous updates on mail queue: If you have ext3 oder reiser NO otherwise better YES
6. Local Networks: 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
7. Procmail for local delivery: Yes
8. Mailbox size limit: 0
9. Local address extension character: +
10. Internet Protocol:All

Edit /etc/postfix/main.cf and add these lines at the end:

smtp_sasl_auth_enable = yes
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = hash:/etc/postfix/sasl_password

Create /etc/postfox/sasl_password with one line:

smtp.1und1.de MAILACCOUNT_at_1und1:PASSWD

Create and db file from this passwd file with

postmap /etc/postfix/sasl_password

Restart postfix with:

/etc/init.d/postfix restart
Now it should work. Give it a try with

date | mail -s “testing” regen@wetter.de

and watch the logfile with

tail -f /var/log/mail.log

One of the best Videos for explaining the shift is from the “Did you know” or “Shift Happens” page from Karl Fisch. More information you can find here.

Additionally a changed something so here are the description for the latest greatest version. I do not repeat his description only point out the changes.

There is a new version of the xmpPHP library available at least a new release candidate.

http://xmpphp.googlecode.com/files/xmpphp-0.1beta-r50.tar.gz

Beside

 cp xmpphp/*.php ../extlib/

also

cp -R xmpphp/XMPPHP ../extlib/

to copy the necessary libraries.
In order to convince apache2 to accept the rewrite it is neccessary to activate the rewrite module with

a2enmod rewrite

/etc/init.d/apache2 force-reload

The XMPP Part is still not running but I try this tomorrow.

Sodale, after a long time my colleagues convinced me to start a blog. Wordpress is now up and running. Lets see what I will write here.
