Facand de curand ordine pe aici am dat peste harta blogosferei si am incercat sa-mi confirm raspunsurile la 2 intrebari: cum a evoluat numarul de posturi? cat de mult se vorbeste in ele despre biciclete? Rezultatul: Bloguri si biciclete 2008 - 2009 Explicatii Primul grafic reprezinta numarul de posturi pe saptamana pentru toate blogurile cuprinse in harta pe perioada oct. 2008 – aug. 2009 Al doilea grafic reprezinta precentual in cate din aceste posturi s-a vorbit despre biciclete....
2 short tricks on ubuntu linux (9.04 Jaunty): Install a .ttf font #create a fonts dir sudo mkdir -p /usr/share/fonts/truetype/myfonts #copy the font sudo cp myFont.ttf /usr/share/fonts/truetype/myfonts #update fonts cache fc-cache -fv Note: if you are using an application don’t expect the fonts to be refreshed dynamically, just restart it. Create a cisco vpn connection apt-get install vpnc Create a /etc/vpnc/myvpn.conf. If you want to convert an existing .pcf file check this article....
After quite some time of development we realised that our application flex has grown quite large, both in functionality and size. I should have chosed to develop it in GWT since I think we could not have done even 30% of the functionality and it would have been simpler :). Joke aside the size of all the modules has grown over 50M. These are some steps I have found in order to reduce the size....
Using a radio button as a data grid cell renderer is an example of a more complex usage of data grid cell renderers. This is one way to achive this in a not very complicated way: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script> <![CDATA[ public var dp:XML = <users> <user> <name>one</name> <main>true</main> </user> <user> <name>two</name> <main>false</main> </user> <user> <name>tre</name> <main>false</main> </user> </users>; ]]> </mx:Script> <mx:VBox> <mx:DataGrid dataProvider="{dp.user}" width="400"> <mx:columns> <mx:DataGridColumn headerText="Name" dataField="name"/> <mx:DataGridColumn headerText="Main"> <mx:itemRenderer> <mx:Component> <mx:HBox horizontalAlign="center"> <mx:Script> <!...
This show a basic way of using Lightbox 2.03 (wiki) into Tapestry 5. First step Just copy the css, images and js/lightbox.js into the web directory. Note: the scriptaculous.js, effects.js and prototype.js are not required as they are already included in T5. Modify the .tml file <html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>My app</title> <link rel="stylesheet" href="${context:css/style.css}" type="text/css" media="screen" /> <script type="text/javascript" src="${context:js/lightbox.js}"></script> <link rel="stylesheet" href="${context:css/lightbox.css}" type="text/css" media="screen" /> </head> …...
Update 11.11.2011, for ubuntu 11.10 oneiric oncelot: you will need version: cx_Oracle-5.0.4-11g-py27-1.x86_64.rpm if using 64bit and you installed oracle on 32 bit thus also installed libaio1:i386 the replace /lib/libaio.1.0.1 32bit with the corresponding version for 64bit or you’ll get: ``` import cx_Oracle ImportError: libaio.so.1: wrong ELF class: ELFCLASS32 ``` - if you try to use a newer version of cx\_Oracle you will get ``` import cx_Oracle ImportError: /usr/lib/python2.7/cx_Oracle.so: undefined symbol: PyUnicodeUCS2_AsEncodedString ``` End update....
This is a small experiment to use my cycling gps device with the navit application on my Acer Aspire One as a car navigation system. The system was composed of the following elements: GPS device Acer Aspire one running Ubuntu linux gpsd navit Navit GPS Required software Step 1. Install all packages required to build navit from ubuntu repositories: apt-get install build-essential pkg-config automake libglib2.0-dev libtool libxmu-dev libfribidi-dev gettext zlib1g-dev cvs gpsd gpsd-clients libgps-dev libdbus-glib-1-dev libgtk2....
Here are some reflections and solutions on how to localize strings in hibernate objects. The model I am assuming the localized strings will be stored in the database in a structure similar to: Table MY_OBJECT: … LOCALIZED_FIELD … Table LOCALIZED_DATA: CATEGORY (object type) LOCALE LOCALIZED_FK (stores the id of the localized object but without foreign key restrictions) FIELD (field of the object) DATA (the actual localization) First ideea (bad) Create a bag of composite elements with the actual localizations:...
A few years ago I was writting some simple tutorials about using hibernate with tapestry to build a simple application. I’ve used Tapestry 3, 4 and I found it reliable to build applications which are still in production. I could consider myself a Tapestry fan and as such I am disappointed a bit to write this article since I was expecting to find no need for it. My goal was to build a simple example of Tapestry – Hibernate application using Tapestry 5....
