http://www.cambus.net/creating-thumbnails-using-phantomjs-and-imagemagick <p>As some people asked for more information about how I render thumbnails for <a

<em>rasterize.js</em> file bundled with <strong>PhantomJS</strong>, configured with a viewport size of 1024x768 and modified to wait 2000 milliseconds before creating output file, in order to allow every page element sufficient time to render.</p> <p>Here is the script :</p> <figure class=’code’><figcaption><span> (rasterize.js)</span> <a

the excellent <strong>OptiPNG</strong> to optimize thumbnails file size.</p> Printing ANSi art 2012-03-15T15:07:00+01:00 http://www.cambus.net/printing-ansi-art <p>I&#8217;ve been printing some ANSi art lately, and figured out I would post something about it.</p> <p>All pieces have been printed at a digital photo printing kiosk using 4R format (which translate into a size of 4&#8221; × 6&#8221; or 102 × 152 mm and a 3:2) ratio.</p> <p>I had to make two batches in order to get the desired results :</p> <ul> <li>For the first batch, I just printed the 16 colors PNG output from <a href="http://ansilove.sourceforge.net">Ansilove</a> to see how it would look like, and I can tell you it didn&#8217;t turn out very well : the aspect ratio was not preserved (which I expected) and the printed material had dull colors.</li> <li>For the second batch, I added some extra black borders around the pictures in order to get a 3:2 ratio and also changed the color profiles to use one optimized for printing : it went much nicer this time, providing pictures with correct aspect ratio and more vivid colors. It&#8217;s still not 100% perfect as the picture still has to be resized by the printer, causing some artefacts on color blocks, but overall the result is more than satisfying and it will do, at least for now.</li> </ul> <p><img src="http://www.cambus.net/content/2012/03/printed-ansi-art.jpg" title="Printed Ansi art" alt="Printed Ansi art" /></p> International Teletext Art Festival 2012-03-09T02:20:00+01:00 http://www.cambus.net/international-teletext-art-festival <p>That&#8217;s it, the <strong>International Teletext Art Festival</strong> is finally live on <a href="http://www.yle.fi/tekstitv/">YLE teletext</a> pages (525-545), to celebrate the 30th anniversary of <strong>teletext in Finland</strong>.

I&#8217;ve been benchmarking VPSes from Linode (<strong>Xen virtualization</strong>) and Tilaa (<strong>KVM virtualization</strong>), along with a dedicated server from Hetzner.</p> <p>Here are the details of each tested configuration :</p> <ul> <li><strong>Linode</strong> : 512MB of RAM, 4 virtual CPUs, 20GB Storage</li> <li><strong>Tilaa</strong> : 256MB of RAM, 1 virtual CPU, 10GB Storage (RAID 10)</li> <li><strong>Hetzner</strong> : Root Server X2, 2GB of RAM, 1 physical CPU, 320GB Storage (SAMSUNG HD321KJ)</li> </ul> <p>Methodology and notes :</p> <ul> <li>Each server have been freshly reinstalled before launching the tests, and no services are running</li> <li>Tests have been ran on Debian 6.0 &#8220;Squeeze&#8221; and on CentOS 6.0, both 32-bit and 64-bit versions</li> <li>The software RAID has been deactivated on the Hetzner dedicated server to avoid causing performance impact</li> </ul> <p>Here is the results summary :</p> <pre> Linode : Debian (32-bit) - System Benchmarks Index Score 1011.4 Linode : Debian (64-bit) - System Benchmarks Index Score 1000.6 Linode : CentOS (32-bit) - System Benchmarks Index Score 920.9 Linode : CentOS (64-bit) - System Benchmarks Index Score 912.3 Tilaa : Debian (32-bit) - System Benchmarks Index Score 1127.3 Tilaa : Debian (64-bit) - System Benchmarks Index Score 1244.0 Tilaa : CentOS (32-bit) - System Benchmarks

Score 818.3 Hetzner : CentOS (32-bit) - System Benchmarks Index Score 673.9 Hetzner : CentOS (64-bit) - System Benchmarks Index Score 623.6 </pre> <p>Please note that these results should be taken cautiously, as they can vary in time (depending on host activity, more precisely disk I/O).</p> <p>Some interesting facts to note however :</p> <ul> <li>Both VPS outperform the dedicated server</li> <li>Performance difference between 32 and 64-bit versions is minimal</li> <li>CentOS always score lower than Debian on all tested systems</li> </ul> <p>Detailed results (CPU information for each host,

World IPv6 launch 2012-03-01T23:55:00+01:00 http://www.cambus.net/getting-ready-for-the-world-ipv6-launch <p>Anticipating for the <a href="http://www.worldipv6launch.org">World IPv6 launch</a> taking place on June 6th, this site is now <strong>IPv6 ready</strong>, and I&#8217;m now proudly displaying a nice IPv6 banner in the sidebar.</p> <p>In fact, you and everyone else should do the same, as it&#8217;s a quite straightforward operation. After configuring IPv6 on your network and <strong>enabling AAAA records</strong> in your DNS server, you just need to make your http server (and eventually mail server as well) listen on IPv6.</p> <p>Here is how to make <strong>nginx</strong> listen to all interfaces on port 80, for both IPv4 and IPv6 :</p> <pre> server { listen 80; listen [::]:80; … } </pre> <p>Then restart nginx, and it will start listening on IPv6 as well :</p> <pre> /etc/init.d/nginx restart </pre> Compiling and running UnixBench on Debian and CentOS 2012-02-27T20:48:00+01:00 http://www.cambus.net/compiling-and-running-unixbench-on-debian-and-centos <p>As I&#8217;m in the process of migrating and reinstalling some VPS and dedicated servers, I figured it would be a nice opportunity to run benchmarks in order to measure system performance in various cases. I will be using <strong>UnixBench</strong> for doing so and will post my results during the next couple of days. Meanwhile, here is a tutorial on installing and running UnixBench.</p> <p>We start by installing (as root) required packages to build the program, follow the instructions related to the <strong>Linux</strong> distribution you are using :</p> <p><strong>Debian</strong> (this should work for <strong>Ubuntu</strong> as well) :</p> <pre> apt-get install build-essential libx11-dev libgl1-mesa-dev libxext-dev </pre> <p><strong>CentOS</strong> :</p> <pre> yum groupinstall "Development Tools" yum install libX11-devel mesa-libGL-devel perl-Time-HiRes </pre> <p>We then fetch and install UnixBench (at the time of writing, the latest version is 5.1.2) :</p> <pre> wget http://byte-unixbench.googlecode.com/files/unixbench-5.1.2.tar.gz tar xvfz unixbench-5.1.2.tar.gz cd unixbench-5.1.2 ./Run </pre> <p>The &#8217;<em>Run</em>&#8217; script will compile everything and launch the tests. Happy benchmarking! :)</p> Drawing Teletext Art 2012-02-21T12:00:00+01:00 http://www.cambus.net/drawing-teletext-art <p>I guess all text mode artists have been dreaming at least once about <del>being employed as a teletext artist</del> drawing <strong>teletext art</strong>, and until very recently, I had no idea that one day I would be able to do so.</p> <p>So here is my first teletext picture ever, it was drawn in January 2012. More stuff will be posted next month, after the <strong>International Teletext Art Festival</strong> goes live on March 8th.

No external dependencies are required (the font data is embedded) and AnsiGo compiles into a single binary file. At the moment you will have to compile it yourself, but I hope to provide binary versions and a Windows executable in the future.</p> <p><strong>Edit</strong> : precompiled binaries for Windows (both 32-bit and 64-bit) are available on the repository.</p> <pre> ——————————————————————————- AnsiGo 1.00 (c) by Frederic CAMBUS 2012 ——————————————————————————- USAGE: ansigo inputfile EXAMPLES: ansigo ansi.ans </pre> <p>The project is hosted on GitHub : <a href="https://github.com/fcambus/ansigo">AnsiGo</a></p> Installing Go on Mac OS X 2012-02-06T17:42:00+01:00 http://www.cambus.net/installing-go-on-mac-os-x <p>Installing <strong>Go</strong> on a <strong>Mac OS X</strong> system is a pretty easy process. In order to do so, you will need to have <strong>Xcode</strong> and <strong>Mercurial</strong> installed; it is possible to download precompiled binary packages from the official Mercurial site, but as I have <strong>Homebrew</strong> installed on this system, that&#8217;s what I&#8217;ve been using instead.</p> <p>In your home directory, type the following command to clone the Go repository :</p> <pre> hg clone -u release https://go.googlecode.com/hg/ go </pre> <p>We then compile everything by invoking the following commands :</p> <pre> cd go/src ./all.bash </pre> <p>On my system, the whole operation is quite fast and takes approximately three minutes to complete (compilation + all unit tests).</p> <pre> real 3m10.309s user 2m48.050s sys 0m41.652s </pre> <p>Finally, you need to set a few environment variables in your <strong>.bash_profile</strong> file :</p> <pre> export GOROOT=$HOME/go export GOOS=darwin export GOARCH=amd64 export GOBIN=$GOROOT/bin export PATH=$PATH:$GOBIN </pre> <p>Congratulations, Go is now installed on your system and you&#8217;re ready to start working with it!</p> RIPE Atlas : an Internet measurement network 2012-02-02T17:34:00+01:00 http://www.cambus.net/ripe-atlas-an-internet-measurement-network <p>I&#8217;ve been taking part in the <a href="http://atlas.ripe.net">RIPE Atlas</a> community since a few weeks already, a project which aims to build the biggest Internet measurement network ever. By doing so, I&#8217;m now hosting a small probe (built around a <strong>Lantronix XPort Pro</strong> module) sent by the <strong>RIPE NCC</strong> which is doing round-the-clock reporting.</p> <p>This is a picture of my setup, the probe is connected to an USB power adapter :</p> <p><img src="http://www.cambus.net/content/2012/01/ripe-atlas-setup.jpg" title="RIPE Atlas Setup" alt="RIPE Atlas Setup" /></p> <p>And here is a closer picture of the probe :</p> <p><img src="http://www.cambus.net/content/2012/01/ripe-atlas-probe.jpg" title="RIPE Atlas Probe" alt="RIPE Atlas Probe" /></p> <p>Basically, the probe is measuring round-trip time (RTT) to the each of the 13 root servers and also does &#8221;<strong>anycast instance discovery</strong>&#8221; measurements, which is precisely why I find this project particularly interesting. Put simply, it allows to know which instance of a given root server you end up querying; for example, when I query the K-root server, I end up connecting to the DENIC operated instance located in Frankfurt (Germany). The RIPE NCC produce publicly available <a href="https://atlas.ripe.net/contrib/maps_index.html">maps</a> using the collected metrics, which allow gravitational radius visualizations for each server instances. For reference, <a href="http://www.root-servers.org">here</a> is list of all root servers instances.</p> <p>Unexpectedly, the probe is also a nice way to monitor my Internet connection, which according to this graph is pretty stable :</p> <p><img src="http://www.cambus.net/content/2012/01/ripe-atlas-uptime.png" title="RIPE Atlas Uptime" alt="RIPE Atlas Uptime" /></p> OpenDNS Stickers 2012-01-30T21:29:00+01:00 http://www.cambus.net/opendns-stickers <p>Earlier last week, I received the <strong>OpenDNS stickers</strong> I requested through their dedicated e-mail account at the end of December. It was a nice suprise, as I was just coming back from work and had totally forgot about this. They are some nice pieces of DNS related collectables, and I couldn&#8217;t resist posting a picture here :)</p> <p>Even if I&#8217;m not using their <a href="http://www.cambus.net/free-public-dns-servers-list/">public DNS servers</a> on a permanent basis, they sure proved useful along the years and saved me more than once in some desperate situations. I should mention that I also appreciate their efforts in raising DNS awareness to the general public. So thank you OpenDNS!</p> <p>PS : They now have a dedicated page for the stickers, and you can request some <a href="http://www.opendns.com/forms/stickers">here</a>.</p> <p><img src="http://www.cambus.net/content/2012/01/opendns-stickers.jpg" title="OpenDNS Stickers" alt="OpenDNS Stickers" /></p> Hurricane Electric IPv6 Certification 2012-01-18T12:55:00+01:00 http://www.cambus.net/hurricane-electric-ipv6-certification <p>I recently completed <a href="http://ipv6.he.net/certification/">Hurricane Electric IPv6 certification</a> and reached the &#8220;Sage&#8221; level. This was a fun and educational process and I would recommend it to anyone interested about the topic, as it&#8217;s a really nice way to start getting familiar with IPv6.</p> <p>Also, I should mention certified IPv6 Sages are entitled to receive a free IPv6 themed t-shirt :)</p> <p><a href="http://ipv6.he.net/certification/scoresheet.php?pass_name=fcambus" target="_blank"><img src="http://ipv6.he.net/certification/create_badge.php?pass_name=fcambus&badge=3" width=229 height=137 border=0 alt="IPv6 Certification Badge for fcambus"></img></a></p> ANSi Web Browser concept 2012-01-03T17:00:00+01:00 http://www.cambus.net/ansi-web-browser-concept <p>This is an attempt at building a <strong>text mode Web browser</strong> interface. It has built in tabs, back and forward buttons, an home button, an address bar with favicon display, bookmark icon, and country flag. It also comes with a few default extensions : a pagerank plugin, a currency converter, a weather plugin, and a music player as well. What else could you ask for? The possibilities are infinite.</p> <p>By the way, in case you wonder if such a browser makes sense in the social media era, the answer is <em>YES</em> : you can of course share the pages on various social media sites. The icons used come from the <a href="http://www.cambus.net/ansi-social-media-icon-set/">ANSi Social Media Icon Set</a> (<strong>CC-BY-SA 3.0</strong> licensed).</p> <p>The rationale behind this design is quite simple : text mode is the undisputed best way to display information on a computer screen. There is no other option.</p> <p>You can download this mockup as an <a href="http://www.cambus.net/files/ansi-web-browser.ans">ansi file</a>, or converted in <a href="http://www.cambus.net/files/ansi-web-browser.png">PNG</a> (with <strong>iCE colors</strong> turned ON) for easier viewing.</p> <p>Happy New Year 2012!</p> <p><img src="http://www.cambus.net/files/ansi-web-browser.png" title="ANSi Web Browser" alt="ANSi Web Browser" /></p> Compiling Apache 1.3.x on modern Linux distributions 2011-11-10T22:37:00+01:00 http://www.cambus.net/compiling-apache-1.3.x-on-modern-linux-distributions <p>For a lot of reasons, some people still want to be able to run <strong>Apache 1.3</strong> on modern Linux distributions, and unfortunately for them, it doesn&#8217;t compile out of the box anymore. The encountered errors are, however, easy to fix and you will learn how to do so in this tutorial.</p> <p>We start by downloading and unpacking sources of the latest 1.3.x version, which happens to be 1.3.42 :</p> <pre> wget http://archive.apache.org/dist/httpd/apache_1.3.42.tar.gz tar xvfz apache_1.3.42.tar.gz </pre> <p>We then run the <strong>configure script</strong> :</p> <pre> cd apache_1.3.42 ./configure </pre> <p>Most likely, this will fail and this error message will get displayed :</p> <pre> + Warning: Your ‘echo’ command is slightly broken. + It interprets escape sequences per default. We already + tried ‘echo -E’ but had no real success. If errors occur + please set the SEO variable in ‘configure’ manually to + the required ‘echo’ options, i.e. those which force your + ‘echo’ to not interpret escape sequences per default. + NOTE: You may also need to edit the shell invoked by + ‘configure’. Some shells (e.g. dash) have a + faulty echo builtin. + using installation path layout: Apache (config.layout) </pre> <p>This happens because in most modern distributions, <strong>sh</strong> is just an alias to <strong>dash</strong>, and dash interprets escape sequences which are therefore not echoed as they should.</p> <p>The workaround is to simply use <strong>bash</strong> instead of <strong>sh</strong> to run the script :</p> <pre> bash ./configure </pre> <p>Now, let&#8217;s compile everything :</p> <pre> make </pre> <p>After compiling a few files, the process will halt with this error :</p> <pre> gcc -c -I../os/unix -I../include -DLINUX=22 -DHAVE_SET_DUMPABLE -DUSE_HSREGEX -DNO_DL_NEEDED `../apaci` htpasswd.c htpasswd.c:101:12: error: conflicting types for ‘getline’ /usr/include/stdio.h:671:20: note: previous declaration of ‘getline’ was here make[2]: *** [htpasswd.o] Error 1 </pre> <p>The internal Apache <strong>getline</strong> function is conflicting with the getline function from the standard I/O library. We can simply fix this by renaming the getline function, which is defined and called in <strong>htdigest.c</strong>, <strong>htpasswd.c</strong>, and <strong>logresolve.c</strong> :</p> <pre> sed -i ‘s/getline/apache_getline/’ src/support/htdigest.c sed -i ‘s/getline/apache_getline/’ src/support/htpasswd.c sed -i ‘s/getline/apache_getline/’ src/support/logresolve.c </pre> <p>Let&#8217;s run make again, and everything should finally compile without problem :</p> <pre> make </pre> <p>Please note, however, that Apache 1.3 branch reached end of life and is therefore depreceated and not supported anymore. It means you will not be getting any bugfixes or security updates and should anything happen, you will have to patch the source files yourself.</p> Setting up a Node.js development environment with NPM and Cloud9 IDE installed locally 2011-11-05T17:45:00+01:00 http://www.cambus.net/setting-up-a-node-js-development-environment-with-npm-and-cloud9-ide-installed-locally <p>In this tutorial, you will learn how to setup a complete <strong>Node.js</strong> development environment, including <strong>NPM</strong> (the Node Package Manager) and <strong>Cloud9 IDE</strong> to edit, run, and debug Node programs. The following installation instructions have been sucessfully tested on <strong>Debian 6.0</strong> &#8220;Squeeze&#8221; and on <strong>Ubuntu 11.10</strong> &#8220;Oneiric Ocelot&#8221;, but they should also work properly on previous versions as well.</p> <p>We will install everything in the user&#8217;s home directory : this way, there is no need for any root access to the machine (provided the required packages are, of course, already installed), and each user can manage its own version of Node.</p> <p>We start by installing (as root) required packages to build Node and later fetch NPM and Cloud9 :</p> <pre> apt-get install build-essential g++ libssl-dev curl git </pre> <p>We create a &#8216;local&#8217; directory within our home directory, and modify our .bashrc file to add it permanently to the $PATH variable :</p> <pre> mkdir ~/local echo ‘export PATH=$HOME/local/bin:$PATH’ >> ~/.bashrc source ~/.bashrc </pre> <p>We fetch, unpack, configure, compile, and install Node. At the time of writing, the latest stable version is 0.4.12, so we simply set the temporary $NODE_VERSION variable accordingly :</p> <pre> export NODE_VERSION=’0.4.12’ wget http://nodejs.org/dist/node-v$NODE_VERSION.tar.gz tar xvfz node-v$NODE_VERSION.tar.gz cd node-v$NODE_VERSION ./configure –prefix=~/local make install cd ~ </pre> <p>We then fetch and install NPM :</p> <pre> curl http://npmjs.org/install.sh | sh </pre> <p>And finally, we install Cloud9 IDE via git :</p> <pre> git clone git://github.com/ajaxorg/cloud9.git </pre> <p>If everything went fine, congratulations, you can now launch Cloud9 IDE and type your first program. First launch can take some time, as the shellscript will need to get some required dependencies prior to run the program.</p> <pre> ~/cloud9/bin/cloud9.sh </pre> <p>Note that the Cloud9 launcher accepts parameters allowing to specify IP and port to listen on, workspace directory, and so on and so far. Below is a list of all available options :</p> <pre> Show this help message –help Load the configuration from a config file. Overrides command-line options. Default: <null> -c, –config <value> Run child processes with a specific group. Default: <false> -g, –group <value> Run child processes as a specific user.

It is, however, a fully featured and highly customizable editor supporting tabbed files, code folding, and language specific syntax highlighting. It is one of my editor of choice for small projects : actually, I&#8217;m typing this article using it.</p> <p>SciTE feels oldschool, a reminiscing gem from a software era when efficiency prevailed over complexity and bloating : in fact it feels so good that I decided to use FVWM (which is, for the record, the first Window Manager I ever used back in early 1996) to take a screenshot.</p> <p><img src="http://www.cambus.net/content/2011/09/scite.png" title="SciTE Screenshot" alt="SciTE Screenshot" /></p> <p>Some interesting facts and features :</p> <ul> <li>It is built upon Scintilla (a source code editing component), and is extendable through Lua scripts.</li> <li>Cross-platform (Good to note : the Windows version is just one single .EXE file!).</li> <li>Interesting selection features : SciTE allows <strong>rectangular block selection</strong> by holding the CTRL key (ALT key under Windows) while defining the selected area.</li> <li>Supports syntax highlighting and code folding for a

Teletext in Germany - Part I 2011-08-17T14:17:00+02:00 http://www.cambus.net/teletext-in-germany-part-i <p>Faster than expected, here comes the second article of my World of teletext serie : it is dedicated to german teletext this time, and contain 110 screens and one video.</p> <p>Unfortunately, I have no idea about the actual state of teletext in Germany, as the country totally switched to digital television through a process completed in 2009. However, analog cable and satellite broadcasts will remain available until 2012, and this is actually how I&#8217;ve been able to capture these screens from France in June 2011 : using an analog satellite decoder with antenna pointed to Astra (19.2°E).</p> <p>This serie contains screens from the following channels : 3sat, ARTE, Bayerisches Fernsehen, Channel 21, Comedy Central, Das Erste, DMAX, Eurosport, hr-fernsehen, Kabel eins, MDR Fernsehen, N24, NDR Fernsehen, Nickelodeon, n-tv, Phoenix, ProSieben, QVC, rbb Fernsehen, RTL, RTL II, Sat. 1, Sport1, Super RTL, SWR Fernsehen, Tele 5, VIVA, VOX, WDR Fernsehen, and ZDF.</p> <p>Overall, Germany was a very interesting country to cover, lots of lovely screens with nice pictures, and spotless design giving access to clear information. Don&#8217;t miss the video at the end of this article featuring a skyline with a gorgeous blinking TV tower!</p> <p>Due to the huge number of pictures, I decided to split it in three parts to allow easier viewing, follow these links to reach the next parts :</p> <p>Second part : <a href="http://www.cambus.net/teletext-in-germany-part-ii/">http://www.cambus.net/teletext-in-germany-part-ii/</a></p> <p>Third part : <a href="http://www.cambus.net/teletext-in-germany-part-iii/">http://www.cambus.net/teletext-in-germany-part-iii/</a></p> <p>3sat :</p> <p><img src="http://www.cambus.net/content/2011/08/teletext-germany-3sat-01.jpg" alt="Teletext 3sat" /></p> <!–more–> <p><img src="http://www.cambus.net/content/2011/08/teletext-germany-3sat-02.jpg" alt="Teletext 3sat" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-3sat-03.jpg" alt="Teletext 3sat" /></p> <p>ARTE :</p> <p><img src="http://www.cambus.net/content/2011/08/teletext-germany-arte-01.jpg" alt="Teletext ARTE" /></p> <p>Bayerisches Fernsehen :</p> <p><img src="http://www.cambus.net/content/2011/08/teletext-germany-bayerisches-fernsehen-01.jpg" alt="Teletext Bayerisches Fernsehen" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-bayerisches-fernsehen-02.jpg" alt="Teletext Bayerisches Fernsehen" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-bayerisches-fernsehen-03.jpg" alt="Teletext Bayerisches Fernsehen" /></p> <p>Channel 21 :</p> <p><img src="http://www.cambus.net/content/2011/08/teletext-germany-channel21-01.jpg" alt="Teletext Channel 21" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-channel21-02.jpg" alt="Teletext Channel 21" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-channel21-03.jpg" alt="Teletext Channel 21" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-channel21-04.jpg" alt="Teletext Channel 21" /></p> <p>Comedy Central :</p> <p><img src="http://www.cambus.net/content/2011/08/teletext-germany-comedy-central-01.jpg" alt="Teletext Comedy Central" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-comedy-central-02.jpg" alt="Teletext Comedy Central" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-comedy-central-03.jpg" alt="Teletext Comedy Central" /></p> <p>Das Erste :</p> <p><img src="http://www.cambus.net/content/2011/08/teletext-germany-das-erste-01.jpg" alt="Teletext Das Erste" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-das-erste-02.jpg" alt="Teletext Das Erste" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-das-erste-03.jpg" alt="Teletext Das Erste" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-das-erste-04.jpg" alt="Teletext Das Erste" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-das-erste-05.jpg" alt="Teletext Das Erste" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-das-erste-06.jpg" alt="Teletext Das Erste" /></p> <p>DMAX :</p> <p><img src="http://www.cambus.net/content/2011/08/teletext-germany-dmax-01.jpg" alt="Teletext DMAX" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-dmax-02.jpg" alt="Teletext DMAX" /></p> <p>Eurosport :</p> <p><img src="http://www.cambus.net/content/2011/08/teletext-germany-eurosport-01.jpg" alt="Teletext Eurosport" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-eurosport-02.jpg" alt="Teletext Eurosport" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-eurosport-03.jpg" alt="Teletext Eurosport" /></p> <p>hr-fernsehen :</p> <p><img src="http://www.cambus.net/content/2011/08/teletext-germany-hr-fernsehen-01.jpg" alt="Teletext hr-fernsehen" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-hr-fernsehen-02.jpg" alt="Teletext hr-fernsehen" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-hr-fernsehen-03.jpg" alt="Teletext hr-fernsehen" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-hr-fernsehen-04.jpg" alt="Teletext hr-fernsehen" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-hr-fernsehen-05.jpg" alt="Teletext hr-fernsehen" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-hr-fernsehen-06.jpg" alt="Teletext hr-fernsehen" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-hr-fernsehen-07.jpg" alt="Teletext hr-fernsehen" /> <img src="http://www.cambus.net/content/2011/08/teletext-germany-hr-fernsehen-08.jpg" alt="Teletext hr-fernsehen" /></p> <iframe width="640" height="510" src="http://www.youtube.com/embed/EAN1geLgEaQ?rel=0" frameborder="0" allowfullscreen></iframe>
