I am officially leaving Windows realm, and forced myself into the unfamiliar territory of Ubuntu Linux. Here are the list of things that I must get them running immediately, or my life will suffer :P.

1. E-Donkey Client. You can use aMule for connecting to ED2K network
2. BitTorrent Client. Azureus have a version that runs in Ubuntu. But emulating uTorrent through Wine also not bad.
3. PeerGuardian for Linux. We have MoBlock, but it doesn’t offer a GUI interface. I believe a GUI development is in progress.
4. Integrated Development Environment (IDE). So far I’m sticking myself to Eclipse for Java. WxGlade for my Python Form Designer. And Eric for Python.
5. and many more … (frankly there are thousands of pages out there offering help on running Ubuntu)

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation=”true”/> in configuration or <%@ Page EnableEventValidation=”true” %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

Event validation is a security measure by ASP.NET to prevent Injection-Attack (i.e. other page post their result to your ASPX page). Turning this option off through the web.config or inside the <%@ Page .. %> tag will guarantee you will never receive above error, but your security might be compromised.

But if your page still producing above error, say when you click a button, or select the value of a server dropdownlist control, these conditions might be applicable to your ASPX page:

1. You have another <form /> tag inside your main Form tag
2. Your AJAX/Javascript code changed the value of a server control
3. You type tags that resemble HTML tags inside a textbox/text-area

What I have today was number 1. I found a <form /> tag inside a < asp:Content .. /> tag. The error came out when I convert my ASP.NET Website project into .NET Web Application Project. So its quite surprising that page never throw any Event validation error during its tenure as Website project. Another possibility is the <form /> was generated by Visual Studio when i convert the project. I’ll do some trial and error more tomorrow…

Search for this at Google:

Invest $1000000 for Movie

And compare the result from Yahoo:

Invest $1000000 for Movie

Surprisingly, my blog is no.2 at Yahoo’s result, but nowhere in Google’s result. I did even try to search within result in Google by adding word ‘Sodeve’, but nada, zilch, nil .. nothing. 😀

I know.. I know.. I should be grateful to Yahoo for putting me in the 2nd spot .. but for the sake of fairness to the poor soul who is trying to get an investor to invest $1 Million in his/her movie project, please use Google next time 😀

As for Yahoo, this means that there are a lot of rooms for improvements in its searching algorithms 😀 (in case the result changed, I put the screenshot HERE)
