			<content:encoded><![CDATA[<p>Creating indexes on Google App Engine / Java (gae/j) is an easy job. You don&#8217;t even have to think about it (well, for some time)</p>
<p>For <a href="http://doganberktas.com/tag/e-tohum/">etohum</a> admin application we used gae/j and it has been almost two years and gae/j has been improved a lot, but still, it has some really annoying features (bugs &#8212; I am not sure how to named them).</p>
<p>This time, it is the <strong>Datastore Indexes</strong>. Some of the pages requires indexes like</p>
<p><img style="margin-top: 5px; margin-bottom: 5px;" src="http://doganberktas.com/wp-content/uploads/2010/09/Screen-shot-2010-09-03-at-4.48.10-PM.png" alt="" width="500" height="21" /></p>
<p>which turns out to be confusing for the auto generation tool. If, let&#8217;s say, you change the order of the last two fields,</p>
<p>like this</p>
<p><img style="margin-top: 5px; margin-bottom: 5px;" src="http://doganberktas.com/wp-content/uploads/2010/09/Screen-shot-2010-09-03-at-4.48.02-PM.png" alt="" width="500" height="21" /></p>
<p>you will not get it automatically.</p>
<p>Even if you explicitly define it in your  <strong>datastore-indexes.xml</strong> file</p>
<pre>&lt;datastore-index kind="Application" ancestor="false" source="manual"&gt;
 &lt;property name="applciationIsFinished" direction="asc"/&gt;
 &lt;property name="isSpam" direction="asc"/&gt;
 &lt;property name="sezonId" direction="asc"/&gt;
 &lt;property name="bitisTarihi" direction="desc"/&gt;
 &lt;property name="basvuruTarihi" direction="desc"/&gt;
 &lt;/datastore-index&gt;
</pre>
<p>And the workaround for the problem is stated in the last paragraph of <a href="http://code.google.com/appengine/docs/java/config/indexconfig.html#Using_Automatic_Index_Configuration">Using Automatic Index Configuration documentation</a></p>
<blockquote><p>It&#8217;s a good idea to occasionally move index configuration from <code>datastore-indexes-auto.xml</code> to <code>datastore-indexes.xml</code>,  then disable automatic index configuration and test your app in the  development server.  This makes it easy to maintain indexes without  having to manage two files, and ensures that your testing will reproduce  errors caused by missing index configuration.</p></blockquote>
<p>So change the <strong>datastore-indexes.xml</strong> file and add manually the all required indexes and upload the application.</p>
<pre>&lt;datastore-indexes autoGenerate="false"&gt;</pre>
<p>You can change it back to auto generate after make sure the desired indexes are created.</p>
<p>ps. A tip about gae/j is that it is considerable faster when it is 4AM-7AM at the west coast of North America.</p>

			<content:encoded><![CDATA[<p>Ankara&#8217;da internet girisimciligi ile ilgili toplanti, soylesi oldukca seyrek oluyor. Gecen donemlerdeki e-tohum toplantilarindan sonra, bu hafta Bilkent Cyberparktaki Microsoft Innovation merkezinde gerceklesen girisimcilik kampi da bu seyrek etkinliklerden biri oldu. Hem yeni insanlarla tanismak hem de canli kanli sektorun aktorlerini gormek motivasyon acisindan tazeleyici oluyor.</p>
<p><img class="aligncenter size-medium wp-image-12" title="Etohum Giri?imcilik kamp? Ankara" src="http://doganberktas.com/wp-content/uploads/2009/08/photo-300x225.jpg" alt="Etohum Giri?imcilik kamp? Ankara" width="410" height="307" /></p>
<p>Microsoft Cyberpark&#8217;in yeni binasinin en ust katini tamamen kapatarak cok guzel bir ofis mekani yaratmis. Her ne kadar tam olarak merkezde neler yapildigi anlasilmasa da uzun vadede umarim bu guzel yatirim somut projeler cikmasina yardimci olur. (bkn openfund office space opportunities in Greece).</p>
<p>Katilimcilar Burak Buyukdemir, Ideshot&#8217;tan Harun Peksen, Nokta&#8217;dan Tuna Orbay guzel konusmalar yaptilar, bir tek son olarak sahnede yerini alan (&#8216;Teknoloji destekleri “KOSGEB, Sanayi bakanligi ve TÜBITAK destekleri&#8217;) – Oguz Yapar, cok iyi niyetli ve acik sozlu olmasina  ragmen kamunun (Sanayi bakanligi ve Tubitak) internet girisimciligi konusunda daha cok yol kat etmesi gerektigini bize cok acik olarak gosterdi.</p>
<p>Ar-Ge/inovasyon ile internet girisimciligi kavramlarini birlestirme henuz kamuda oturmus degil. Internet projelerini e-ticaret programi kurma olarak goruluyor. Ar-Ge yapmak, yenilikci olmak &#8220;elle tutulur-(fiziksel anlamda)&#8221; urunler cikarmakla esdeger tutuluyor. Burak hoca cay molasinda Oguz beye soyledigi tek bir cumle ile Istanbul-Ankara mantigi arasindaki farki somutluyor: &#8220;&#8230;bu sekilde Turkiye&#8217;den Twitter cikmaz!&#8221;.</p>
<p>Benden de Burak hocaya bir ek o zaman, &#8220;Iyi niyetli de olsa destegi dagitanlar, Twitter&#8217;in ne oldugunu bilmeyen hocalar oldugu surece Turkiye&#8217;den Twitter cikmasina nasil on ayak olabilirler?&#8221;</p>
