			<content:encoded><![CDATA[<p>
While my daughter was working on a school project, she was looking for a fully searchable text of &#8220;Animal Farm&#8221; from George Orwell and found it on the Australian web site <a href="http://gutenberg.net.au" title="Project Gutenberg, Australia | gutenberg.net.au">Project Gutenberg Australia</a>. The offer was legal, but had she downloaded the text, she would have committed a serious crime, a copyright violation. Two more, and our entire family would be eligible for disconnection from the Internet &#8211; at least in some European countries.
</p>
<p>
A little background: prior to the US-Australian Free Trade Agreement from 2005, copyright in Australia expired 50 years after the authors death. After the FTA was signed in 2005, copyright now expires 70 years after the authors death. That&#8217;s how it is in Europe, too.
</p>
<p>
George Orwell, the author of &#8220;Animal Farm&#8221;, &#8220;Nineteen Eighty-Four&#8221;, and four other novels, died January 21st, 1950. So in Australia, his works where in the public domain since 2001. And that didn&#8217;t change with the FTA from 2005. While George Orwell&#8217;s novels are not in the public domain and are still under copyright in Europe, the opposite is true for Australia. That&#8217;s why Australian web sites like Project Gutenberg Australia can legally offer George Orwell&#8217;s works for download. George Orwell&#8217;s works are also in the public domain in Russia and Canada. In Europe, his works will be in the public domain in 2021, and even later in the US.
</p>
<p><span id="more-164"></span></p>
<p>
Who does expect a kid to know that? If I buy a book, I can legally lend it to as many people as I like. That I can lend it to only one person at a time is a technical limitation of the thing called &#8220;book&#8221;. Files containing text, music, or film don&#8217;t have that technical limitation. Copying and giving it to as many people simultaneously is possible and intuitive. That&#8217;s why kids do it all the time. That copyright violations by copying files are described as &#8220;stealing&#8221; is also counter-intuitive. After you copy a file, it&#8217;s not taken away from the original owner, but you&#8217;ve made one thing more. If a kid finds something useful on the Internet it will probably use it in intuitive ways: copy it, share it &#8211; and thereby potentially breaking the law.
</p>
<p>
Ok, you can educate the kid in order to minimize copyright violations, but &#8211; as shown with &#8220;Animal Farm&#8221; &#8211; you cannot eliminate them completely without making your kid a copyright lawyer. Other options are removing access to the Internet or supervising your kid all the time.
</p>
<p>
Accessing the Internet via a trustworthy VPN (virtual private network) service provider is another option. My VPN service provider is <a href="http://ipredator.se" title="Ipredator | ipredator.se">Ipredator</a>. How to set it up on Windows and OSX is shown on their web site. Instructions for Ubuntu Linux can be found <a href="http://christianengstrom.wordpress.com/2010/03/07/installing-ipredator-under-ubuntu-linux-9-10" title="Christian Engström, Pirate Member of the European Parliament | wordpress.com">here</a>. I&#8217;ll now show you how to set it up under Android 1.6:
</p>
<p>
Go to &#8220;Settings > Wireless controls > VPN settings&#8221; and add a new VPN with &#8220;Add VPN > Add PPTP VPN&#8221;.
</p>
<p>
<img src="http://blog.synformation.com/wp-content/uploads/add-vpn.png" alt="" title="Add a VPN" width="240" height="105" class="alignnone size-full wp-image-171" />
</p>
<p>
Enter the following information:</p>
<pre>
VPN name: Ipredator
Set VPN server: vpn.ipredator.se
PPT encryption is enabled
</pre>
</p>
<p>
<img src="http://blog.synformation.com/wp-content/uploads/vpn-settings.png" alt="" title="VPN settings page" width="240" height="233" class="alignnone size-full wp-image-178" />
</p>
<p>
Now, you&#8217;re ready to connect to the VPN. Tap on &#8220;Ipredator&#8221; to connect.
</p>
<p>
<img src="http://blog.synformation.com/wp-content/uploads/before-connect.png" alt="" title="Before connecting to VPN" width="240" height="155" class="alignnone size-full wp-image-172" />
</p>
<p>
Fill in the required account information (user name and password). Hit &#8220;Connect&#8221;.
</p>
<p>
<img src="http://blog.synformation.com/wp-content/uploads/connect.png" alt="" title="Connect to the VPN" width="240" height="309" class="alignnone size-full wp-image-173" />
</p>
<p>
You&#8217;re now connected to your VPN service provider &#8211; see the key in the status bar marked red (I added the marks with Gimp)?
</p>
<p>
<img src="http://blog.synformation.com/wp-content/uploads/connected.png" alt="" title="Connected to the VPN" width="240" height="155" class="alignnone size-full wp-image-174" />
</p>
<p>
Safely surf the Internet.
</p>
<p>
<img src="http://blog.synformation.com/wp-content/uploads/surf-save.png" alt="" title="Surfing the web savely with VPN enabled" width="240" height="137" class="alignnone size-full wp-image-177" />
</p>
<p>
While surfing the web, you can get information on the VPN connection.
</p>
<p>
<img src="http://blog.synformation.com/wp-content/uploads/info.png" alt="" title="Information about VPN connection" width="240" height="125" class="alignnone size-full wp-image-176" />
</p>
<p>
To Disconnect from your VPN service provider, go to &#8220;Settings > Wireless controls > VPN settings&#8221; again.
</p>
<p>
Tap on the VPN named &#8220;Ipredator&#8221; to disconnect.
</p>
<p>
<img src="http://blog.synformation.com/wp-content/uploads/disconnected.png" alt="" title="Disconnected from the VPN" width="240" height="155" class="alignnone size-full wp-image-175" />
</p>
<p>
If you switch from 3G network to WLAN, you&#8217;ll be disconnected from Ipredator. Just reconnect.
</p>
<p>
I know that PPTP is vulnerable to some sorts of attacks, but using VPN with Ipredator (or other VPN service providers) that way is more of a political statement: we need to change copyright law! All non-commercial copying and sharing of files needs to be legal. Otherwise it&#8217;s done anyway and as safely as possible. Trying to prevent people from doing it is like trying to prevent people from Iran or China to access certain parts of the Internet: it will not work.</p>

			<content:encoded><![CDATA[<p>One of our girls visits the 7th grade (13 years, secondary school) right now. In geometry, they are talking about the congruence rules for triangles and triangles in general. Yesterday&#8217;s homework included a geometrical problem: construct the space diagonal of a cube geometrically and specify its length (side length of the cube is 5.3cm).</p>
<p>While this might be an easy problem for grownups, it seemed not so easy for her. She drew a grid model of the cube, connected the opposite vertices, and measured off the length of the resulting diagonal. It seem logical and right for her. When I asked her about the actual angles in a cube, and how they relate to her projection, it became quite clear, that some angles in the drawing weren&#8217;t quite what they should have been.</p>
<p><span id="more-32"></span></p>
<p>In my opinion, kids have to learn how to ask the right questions, and how to find answers. And then they should explain it to somebody else. As a freshman I earned some extra money by giving private lessons for juniors and seniors. I quickly learned, that I was only able to explain a problem and its solution in depth, when I was able to answer all kinds of questions they were throwing at me. It didn&#8217;t have anything to do with knowledge, but with the ability to express it. And that is quite harder. So whenever you want to make sure you truly understand something, talk to someone about it for a couple of minutes, and have her or him ask you questions.</p>
<p><img src="http://blog.synformation.com/wp-content/uploads/diagonal.png" alt="Constructing the space diagonal of a cube geometrically" /></p>
<p>Finally, she was able to find a solution to the problem. I didn&#8217;t explain it to her, but I asked her some questions. She had to explain it to me.</p>

			<content:encoded><![CDATA[<p>Yesterday, I received a phone call from someone who asked me to meet aircraft N279WA in <a href="http://en.wikipedia.org/wiki/Frankfurt_International_Airport" title="Frankfurt Airport Information | http://wikipedia.org">Frankfurt</a> on a cargo mission. It came from Chicago and went back to Atlanta.  This aircraft has been converted to a cargo plane only recently. And it has a new livery now.</p>
<p><img src="http://blog.synformation.com/wp-content/uploads/b1.png" alt="Aircraft N279WA during push back from position F215" height="150" width="400" /></p>
<p><span id="more-22"></span></p>
<p>Before, it was a passenger aircraft. I knew it mostly from <a href="http://www.amc.af.mil" title="Air Mobility Command Homepage | http://af.mil">Air Mobility Command</a> missions. On several occasions, I flew with it from the now defunct <a href="http://www.af.mil/news/story.asp?storyID=123011993" title="Rhein-Main mission ends, but not its legacy | http://af.mil">Rhein-Main AFB</a> to <a href="http://www.globalsecurity.org/military/facility/udeid.htm" title="Al Udeid Air Base, Qatar | http://globalsecurity.org">Al Udeid AFB</a> in Qatar. Most flights went thru Bahrain airport, because the commercial air carriers need a place to change crews and get catering. This is difficult to accomplish on some Air Force Bases, but certainly in Al Udeid. The AMC missions are still going on, but without this aircraft.</p>
<p><img src="http://blog.synformation.com/wp-content/uploads/b2.png" alt="Empty main deck" height="310" width="400" /></p>
<p>While I was there, I took some pictures, one from the main deck after unloading of the inbound cargo. The main deck alone on this <a href="http://www.boeing.com/commercial/md-11family/index.html" title="Boeing's MD-11 Family| http://boeing.com">MD-11</a> can hold  more than 150,000 lbs of cargo. Loading teams in Frankfurt regularly load an entire MD-11 cargo aircraft in 45 to 60 minutes.</p>
<p><img src="http://blog.synformation.com/wp-content/uploads/b3.png" alt="Me in the cockpit" height="310" width="400" /></p>
<p>Here you can see a portion of the N279WA cockpit from that night, with me in the captains seat. Although I know how to read and use some of the instruments, I can barely fly an aircraft with <a href="http://www.microsoft.com/games/flightsimulatorx" title=" Microsoft Flight Simulator X Website | http://microsoft.com">Microsoft&#8217;s Flight Simulator</a>. But then, this isn&#8217;t my job.</p>

			<content:encoded><![CDATA[<p>For our family car, a 2006 Mercedes-Benz C-class station wagon, I wanted to be able to connect a MP3 player to the car audio system. We have an iPod and the girls have some other MP3 players as well. Although the CD player in the car can play MP3 CDs, it doesn&#8217;t always work. It seems to depend on the manufacturer of the blanks as well as the software the MP3 CD has been recorded with.</p>
<p><img src="http://blog.synformation.com/wp-content/uploads/mb.png" id="image17" alt="2006 Mercedes-Benz C-class station wagon" height="265" width="400" /></p>
<p><span id="more-16"></span></p>
<p>I have considered the <a href="http://www.apple.com/pr/library/2005/jan/11mercedes.html" title="iPod Integration Kit | http://apple.com">iPod Integration Kit</a> for USD 299 plus cost of installation. But with it you can operate the iPod only from the steering wheel. And I don&#8217;t want to be the DJ while driving. The front-seat passenger should do that if needed. Because of that, I bought a simple cable harness from Mercedes-Benz to setup the AUX input of the Audio 20 for connecting directly to the iPod. The Mercedes-Benz cable harness part no. is 203 540 61 07 if you order it in the US, or 210 440 50 05 for Europe. It should cost approx. USD 30. Installation is easy and should take around 30 minutes if you <a href="http://forums.mbworld.org/forums/showthread.php?t=81978" title="Setting up the AUX input for iPod | http://mbworld.org">do it yourself</a>. If you&#8217;re using an European iPod, you should <a href="http://gopod.free-go.net" title="Release the sound of your iPod | http://free-go.net">uncap the iPod volume</a>. Otherwise, it will not be loud enough.</p>
<p><img src="http://blog.synformation.com/wp-content/uploads/ipod.png" id="image18" alt="iPod connected to the AUX input" height="235" width="400" /></p>
<p>Everybody is happy now as we&#8217;re able to connect any MP3 player to our cars audio system. And because the connector is hidden inside the glove compartment, no cables are hanging around. Thanks to playlists, there&#8217;s no need to access the MP3 player very often.</p>
