			<content:encoded><![CDATA[<p>Unit tests do not solve all your problems and sometimes, you can simply not use them (or in very difficult way, e.g. when you are designing GUI). But they are suitable, if used properly. For JavaScript, this was a bit problem. </p>
<p>
Several unit tests suits are out there, you can see a nice list on <a href="http://www.opensourcetesting.org/unit_javascript.php>Opensourcetesting.org</a>, but most of them do require server-side scripts (promissing JsUnit among others). Isn&#8217;t there something simple? I have tried <a href="http://jsassertunit.sourceforge.net/docs/index.html">JavaScript Assertation unit framework</a>, which was both &#8211; easy to be installed and easy-to-be used, and JavaScript-only (nor server-side needed). OpenLayers <a href="http://openlayers.org/dev/tests/run-tests.html">is using</a> <a href="http://openjsan.org/doc/a/ar/artemkhodush/Test/AnotherWay/0.52/lib/Test/AnotherWay.html">test anotherway</a> suit,  but after that, <a href="http://fireunit.org/">Fireunit</a> caught my eye.</p>
<p>
If you have <a href="http://getfirebug.com">Firebug</a> installed (which is assumed), just install other plugin &#8211; Fireunit. The project seems to be pretty new, but yet usable. You can <a href="http://wiki.github.com/jeresig/fireunit/examples">follow some examples</a>, which can be found &#8211; it is as easy as possible. </p>
<p>
This will give you unit tests, integrated to the browser &#8211; no server-side installation, works everywhere any time, no configuration &#8211; just works out of the box. Too nice to be truth, but yet seems to be, by now.</p>

			<content:encoded><![CDATA[<p><a href="http://pywps.wald.intevation.org">PyWPS</a> is now able to run as Java Servlet within <a href="http://tomcat.apache.org">Tomcat</a>. It is possible to access Java objects from PyWPS and to access PyWPS methods from Java. How this is possible?</p>
<p>Several steps have been provided, to get it working. And the main one is, that PyWPS runs with <a href="http://jython.org">Jython</a> as interpreter. My feeling is, that is is not Python anymore, but Java with Pythonish syntax. Anyway, it looks like little magic to me, but seems to be working. Documentation will follow soon.</p>

			<content:encoded><![CDATA[<p>I was providing packages of GIS related software for Ubuntu distributions, because of I was packaging the software for me anyways and I just let them on the server. Many people seemed to be using them, but it is truth, that with the time, I moved from desktop-gis world to web-gis. I had no time to test the software properly and many times it was simply not working. But still, the <a href="/2009/05/grass-64-rc4-for-ubuntu-904/">GRASS 6.4 rc4 for Ubuntu 9.04</a> was the most commented post on this blog.</p>
<p>I will stop now to compile custom packages, at least, until <a href="">Ubuntu GIS</a> will provide up-to-date packages, which are working. Many thanks to all Ubuntu-GIS people, they are doing a good job.</p>
<p>So, now, all who want to have up-to-date software, add</p>
<pre>
deb http://ppa.launchpad.net/ubuntugis/ubuntugis-unstable/ubuntu karmic main
deb-src http://ppa.launchpad.net/ubuntugis/ubuntugis-unstable/ubuntu karmic main
</pre>
<p>to your <code>/etc/apt/sources.list</code> file (works for jaunty too).</p>

Eventhough, we <a href="http://geoportal.bnhelp.cz/map">are using</a> complex JavaScript frameworks, such as <a href="http://extjs.com">ExtJS</a> and <a href="http://openlayers.org">OpenLayers</a>, live is never that easy. Our usual communication is like &#8220;Firefox 3.0 works, 3.5 works as well, IE 7 works, IE 8: Error on line 753, character 110, Chrome works, Opera works, Safari seems to be working as well.&#8221; </p>
<p>You can have every possible webbrowser in your system in any possible version, except for IE. I, as Linux user, am the only one in the team, who can test on all currently used Explorer versions. I would be happy, if I needn&#8217;t. Do you have similar problems?</p>

			<content:encoded><![CDATA[<p>Tento týden jsem se účastnil akce <a href="http://www.fossgis.de/konferenz/wiki/Main_Page">FOSSGIS 2009</a> &#8211; největší německé OpenSource GIS konference. Jako každý rok, byl i tento super, účast bohatá (přes 470 účastníků, cca 10 vystvavujících firem). Vedle firemních stánků měli svoje stánky i OpenSource projekty, <a href="http://www.flickr.com/photos/timlinux/3362714870/in/photostream/">QGIS</a> a <a href="http://wiki.openstreetmap.org/wiki/FOSSGIS_2009">OpenStreetMap</a>. </p>
<p>Setkání bylo inspirující do té míry, že jsem se opět ve volných chvílích začal bavit PostGISem a pro začátek jsem do něj nahnal kompletní data českých OpenStreetMap &#8211; připojení na MapServer bylo už dílem okamžiku.</p>
<p>Byl jsem velmi mile překvapen, jak daleko je dneska <a href="http://qgis.org">QGIS</a>. Měl jsem s <a href=http://blog.qgis.org/?q=blog/3"">Timem Suttonem</a> společné ubytování u Oťáka (německy Otto Dassau) a tak jsem měl spoustu novinek z první ruky. Stejně jako on musel, chudák, vyslechnout hned na úvod přednášku o PyWPS. Jeden příklad za všechny: <a href="http://www.fossgis.de/konferenz/wiki/Historisierung_von_PostGIS-Daten">ukládání historie změn vektorových dat do PostGISu a zobrazování v QGISu</a>.</p>
<p>No, pln inspirací, očekávání atd. jsem neodolal a vygeneroval jsem <a href="/data/osm/cr/">routovatelnou mapu České republiky</a> s názvy ulic jako POI (takže se v tom dá vyhledávat) pro Garminy.  Německá verze téhož má asi 300MB (dostal jsem ji přímo od Jochena Topfa). Česká mapka má jenom 35MB tak doufám, že to souvisí s podrobností dat a ne s nějakou hrubou chybou na mé straně. Jochen se mimochodem divil, jak to že je česká OSM komunita tak aktivní, že tam přibývají data neskutečným fofrem a naposled si všimnul, že se nějak podezřele rychle zaplňují poštovní směrovací čísla. Uklidnil jsem ho, že většina dat pochází z exportů. Na rozdíl od Německa, kde jsou mapy výsledkem mravenčí práce jednotlivců s GPSkama.</p>
<p>Taky jsme měli PyWPS Workshop. Ten se bohužel poněkud minul účinkem. Když jsem se zhruba po první třetině ptal, kdo dostal GetCapabilities (po podrobně vysvětlené instalaci a konfiguraci), tak se přihlásila polovina lidí. Po deseti minutách, když jsem se přes DescribeProcess prokousal až k Execute už se nehlásil nikdo &#8211; zklamání na celé čáře.  Holt to bylo zaměřený pro trochu jiné účastnjíky a ne pro naprosté začátečníky, kteří se bojí klávesnice a příkazové řádky &#8211; škoda.</p>
<p>Doufám, že příští rok v Osnabrücku nebudu už za ČR-SR sám.</p>
