				<content:encoded><![CDATA[<p>&#8220;The programmers of tomorrow are the wizards of the future. You are going to look like you have magic power, compared to everybody else.&#8221; Diese Aussage beschreibt den Wert, den &#8220;Coding Skills&#8221; heute und in Zukunft haben. Die Fähigkeit Software nach eigenen Vorstellungen zu entwickeln stellt für jeden Bürger eine wichtige Möglichkeit dar das Grundrecht der Freiheit auszuleben.</p>
<p>Das folgende Video beschreibt was &#8220;die meisten Schulen (noch) nicht lehren&#8221; nämlich Software zu entwickeln und Quellcode lesen zu können.</p>
<p><iframe src="https://www.youtube.com/embed/dU1xS07N-FA" height="315" width="560" allowfullscreen="" frameborder="0"></iframe></p>
<p>Meine ersten Schritte der Programmierung mit habe ich im Alter von vierzehn Jahren mit den Programmiersprachen Java und PHP gemacht. Wann habt ihr mit dem Programmieren begonnen und was waren eure ersten Erlebnisse?</p>

<h2>Recent Changes (v3.1)</h2>
<ul>
<li>Displaybeleuchtung verbessert (Transparenz entfernt)</li>
<li>Swipe nach rechts =&gt; Bildschirm blau färben</li>
<li>Swipe nach links =&gt; Bildschirm rot färben</li>
<li>Swipe verbessert</li>
</ul>
<h2>Recent Changes (v3.0)</h2>
<ul>
<li> Möglichkeit die App zu starten indem man die Suchtaste gedrückt hält</li>

				<content:encoded><![CDATA[<h2>Machine Learning Class</h2>
<p>Machine Learning has always been a topic that attracted my interest. Currently I attend the &#8220;<a title="Machine Learning Class" href="http://www.ml-class.org" target="_blank">Machine Learning</a>&#8221; class (<a title="@ml_class" href="http://twitter.com/ml_class" target="_blank">@ml_class</a>) offered by Prof. <a title="Prof. Andrew Ng" href="http://ai.stanford.edu/%7Eang/" target="_blank"><span class="zem_slink">Andrew Ng</span></a> from <a class="zem_slink" title="Stanford University" href="http://en.wikipedia.org/wiki/Stanford_University" rel="wikipedia">Stanford University</a>. The class is awesome. The video lectures are made of small chunks explaining every topic in detail. A lot of topics were already covered:</p>
<ul>
<li><a class="zem_slink" title="Linear regression" href="http://en.wikipedia.org/wiki/Linear_regression" rel="wikipedia">Linear regression</a> with one variable</li>
<li>Linear regression with multiple variable</li>
<li>One-vs-all Classification</li>
<li>Regularization</li>
<li>Backpropagation Algorithm</li>
<li>Neural Networks</li>
<li>Practical advise for applying learning algorithms</li>
<li>How to develop and debug learning algorithms</li>
<li>Feature and model design, setting up experiments</li>
</ul>
<p>Other interesting topics are following. In parallel to the lectures there are homework programming exercises that have to be solved. To date programming assignments covering topics as:</p>
<ul>
<li>Linear regression</li>
<li>Logistic regression</li>
<li>Multi-class classification and Neural Networks</li>
<li>Neural network learning</li>
<li>Regularized linear regression and bias-variance</li>
</ul>
<p>In order to solve the exercises you have to understand the contents and have some programming experience in <a title="GNU Octave" href="http://www.gnu.org/software/octave/" target="_blank">GNU Octave</a>. It is also important to have basic understanding of Linear Algebra.</p>
<h2>Machine Learning Contests</h2>
<p>In order to apply machine learning on real world problems you can enter a machine learning contest. There are various contests out there, some of which are</p>
<ul>
<li><a title="Tuned IT" href="http://tunedit.org/" target="_blank">Tuned IT</a></li>
<li><a title="Kaggle" href="http://www.kaggle.com/" target="_blank">Kaggle</a></li>
</ul>
<p>I will keep you updated.</p>

				<content:encoded><![CDATA[<p>Vor kurzem wurde in Österreich der <a title="E-Control Spritpreisrechner" href="http://spritpreisrechner.at/" target="_blank">Spritpreisrechner der E-Control</a> offiziell der Öffentlichkeit vorgestellt. Es hat nicht lange gedauert, bis auch die ersten Android App Entwickler die Seite zu nutzen versuchten. So finden sich derzeit im Android Market schon einige <a title="Android Market Spritpreisrechner Apps" href="https://market.android.com/search?q=spritpreisrechner&amp;so=1&amp;c=apps" target="_blank">Spritpreisrechner Apps</a>.</p>
<p>Ich habe mir einmal das Datenformat angesehen, welches die Website spritpreisrechner.at für die Abfrage der Spritdaten benutzt. Es ist eigentlich ganz einfach:</p>
<p>Es werden per HTTP POST Request Anfragen an <a title="http://spritpreisrechner.at/espritmap-app/GasStationServlet" href="http://spritpreisrechner.at/espritmap-app/GasStationServlet" target="_blank">http://spritpreisrechner.at/espritmap-app/GasStationServlet</a> geschickt. Wichtig ist dabei der Parameter &#8220;data&#8221; der natürlich mit Werten (Längen- und Breitengraden bzw. einen Suchstring) initialisiert werden muss.</p>
<p>Beispielsweise könnte man folgenden cURL Aufruf ausführen (die Daten in &#8220;data&#8221; sind url-encoded&#8221;):</p>
<pre class="brush: bash; title: ; notranslate">
curl -d &quot;data=%5B%22Graz%22%2C%22DIE%22%2C15.414262484145%2C47.057105360725%2C15.494085024429%2C47.08048974931%5D&quot; http://spritpreisrechner.at/espritmap-app/GasStationServlet
</pre>
<p>Der HTTP Request Header sieht konkret folgendermaßen aus:</p>
<pre class="brush: plain; title: ; notranslate">
Request URL:http://spritpreisrechner.at/espritmap-app/GasStationServlet
Request Method:POST
Status Code:200 OK

<p>Der Parameter &#8220;data&#8221; enthält einen JSON String der mit folgenden Werten befüllt wird:</p>

</pre>
<p>Longitude 1 und Latitude 1 geben Koordinaten der linken unteren Ecke, Longitude 2 und Latitude 2 die Koordinaten der oberen rechten Ecke an. Das so aufgespannte Rechteck definiert den sichtbaren Bereich auf der Google Maps Karte. Im Zentrum sollte sich sinnvollerweise die aktuelle Position befinden. Innerhalb des sichtbaren Bereiches werden die 5 billigsten Tankstellen mit den dazugehörigen Spritpreisen angezeigt. Um das Rechteck aufzuspannen kann man sich in Android folgendermaßen behelfen:</p>
<p>1. Aktuelle Position mittels Android LocationManager ermitteln<br />
 2. Mittels der aktuellen Position und der Methoden <a title="getLongitudeSpan()" href="http://code.google.com/intl/de-DE/android/add-ons/google-apis/reference/com/google/android/maps/MapView.html#getLongitudeSpan()" target="_blank">getLongitudeSpan()</a> und <a title="getLatitudeSpan()" href="http://code.google.com/intl/de-DE/android/add-ons/google-apis/reference/com/google/android/maps/MapView.html#getLatitudeSpan()" target="_blank">getLatitudeSpan()</a> die rechte obere und die linke untere Ecke berechnen und anschließend<br />
 3. Parameter &#8220;data&#8221; mit den ermittelten Werten befüllen und HTTP Post Request abschicken.</p>
<p>Wird der oben beschriebene HTTP Request ausgeführt, bekommt man als HTTP Response einen JSON String, der wie folgt aufgebaut ist:</p>
<pre class="brush: plain; title: ; notranslate">

<p>Einen Parser für diesen JSON String zu schreiben, dürfte nicht allzu schwer sein. <img src='http://blog.muehlburger.at/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' />  Das war auch schon alles um eine App für spritpreisrechner.at entwicklen zu können. Eigentlich ziemlich einfach. Was meint ihr? Freu mich auf Kommentare und Anregungen!</p>
