Hello World! This is me..
After generating hibernate files using ant tasks the column names and table names has to be edited.
say generated code
This has to be edited as,
I use the following sed commands to do this.
sed -i ’s|table=”\([a-zA-Z_]*\)”|table=”\"\1\"”|g’ table.hbm.xml
sed -i ’s|column name=”\([a-zA-Z_]*\)”|column name=”\"\1\"”|g’ table.hbl.xml
sed -i ’s|schema=”\([a-zA-Z_]*\)”|column name=”\"\1\"”|g’ table.hbm.xml
I started trying out gnome-do when I read an article about the upcoming ontology based tools (gnome-do and ubiquity) in Linux for you. There are many plug-ins available for gnome-do (official and community). I am using Debian(lenny) and had a hard time in setting it up. Setting up do from source was easy, but setting up the plug-ins from source was hard. Do plug-ins (0.8.3) depends on banshee (>=1.4.3), but debian lenny had a lesser version. Then I tried to set up banshee from source which again asked for gstreamer-* > 0.10.3 which was not available in Lenny. Moreover the first step for building banshee in Lenny has failed (apt-get build-dep banshee). Finally, I migrated to debian testing and got gnome-do and its plug-ins from debian repository without any problem. Its time to start our own plug-in, before proceeding to this step, I tried to build a plug-in( EOG-Slideshow ) that is available already in launchpad. All you have to do is,
1. run gnome-do from terminal
2. open the project file in monodevelop
3. build it from Monodevelop.
4. Now, open the plug-ins list by clicking on do in system tray and selecting the preferences. The list of plug-ins available are listed here.
5. We have to drag the dll (which we had compiled just now) and drop it in.
6. Terminal should show the status that the plug-in is getting installed. once it is installed then we shall enable it and start using.
Now, lets start writing the plug-in, the simplest plug-in that I found on net is Google-Search. There are few changes required (we need to include .addin.xml for the plug-in and we should inherit Act etc..).
HelloWorld.cs:
using System;
using System.Collections.Generic;
using System.Linq;
using Do.Universe;
namespace HelloWorld
{
class HelloWorldAction : Act
{
public override string Name {
get { return “HelloWorld”; }
}
public override string Description {
get { return “Say Hello World.”; }
}
public override string Icon {
get { return “search”; }
}
public override IEnumerable SupportedItemTypes {
get { return new Type[] { typeof (ITextItem) }; }
}
public override IEnumerable Perform (IEnumerable items, IEnumerable modItems) {
string query = (items.First() as ITextItem).Text;
System.Diagnostics.Process.Start(”/usr/bin/xmessage”, ” -center -default okay hello, ” + query);
return null;
}
}
}
HelloWorld.addin.xml:
<Addin
id=”HelloWorld”
namespace= “Do”
version=”0.1″
name=”HelloWorld”
description=”Say Hello World.”
author=”SatheeshKumar Mohan”
category=”Community”
>
how to compile it?
$ gmcs -target:library -r:/usr/lib/gnome-do/Do.Universe.dll HelloWorld.cs “/res:HelloWorld.addin.xml”
That’s it, add the plugin to gnome-do as we did earlier and enable it. Just launch do, type anything say, sathyz and select the action “hello world”, it will display an xmessage saying “Hello, sathyz”.
The principle is this action is supported for any text item, (so the source here is text) and action to perform is show a dialog saying hello, # that text#. In the next part l am trying to get data from a specific source, say the data for Rhythmbox comes from rhythmbox.db,for ssh connect it is ~/.ssh/config.
just tried firefox persona. Love my firefox after that.. 
we used SimpleFormController for handling forms, in which we had onSuccess mapped to url say, ‘/uploadSuccess’. The problem with this was, after submitting the form the user would be taken to “/uploadSuccess”. if user presses refresh in browser or if the user goes to some page and comes back using the back button the form would be resubmitted. To avoid this, use ‘redirect:/uploadSuccess’.

The following solution worked for me,

I have been looking for a good subversion client on Linux and started using nautilussvn. That’s pretty cool, since it works from the file browser and pysvn based.
Installation is easy process. I used deb package from the nautilussvn home page on my Debian (unstable).
Still using meld for comparison and that’s also look cool. Have to try using Gvidiff.
Using nautilussvn, could see the modified files, files that are not added to repository, files that are added etc. with good emblems on them. Moreover, we can do svn actions like add, commit, revert etc also by simply right clicking the file.
It is still in development. Check out the screenshots and tutorials on hacking nautilus on that same website.
Here are the few links that I got that helps you in testing your browser. (check the results for your browser too).
Embedding video in HTML is very easy now, (no need to code streaming apis).
All we need to do is just use videos same as how we embed image. Firefox3.1 has this feature enabled and its very simple.
<video src="videofile.ogg" autoplay>
Your browser does not support the <code>video</code> element.
</video>
This will embed video in your page and starts steaming when sufficient data has been received.
