My uncle's computer got some problems a few days ago. After the prower is on, there is only a black screen. He asked me why.
There are some possible cause:

• Hard disk/CD Rom failure, causing a kind of dead lock of the checking process
• Motherbroad burned down.
• RAM problem
• BIOS problems, maybe there are some kind virus

Finally, the tech guy found that is a RAM problem. After he changed a new set of RAM, all good.

Opensource vs Microsoft?No, No, No. That is Open Source at Microsoft They got their Open Source Software Lab.

P.S. Microsoft is announced Silverlight for Linux

I got a lot of memory usage in FireFox. After I have opened several tabs, the memory usage will raise a lot.

Does anyone face this problem too?

I am finding a RSS for the extension directory joomla. But no luck for this at this moment. Why am I so keen about this RSS? Because I wish to know the latest updates for all Joomla components. Almost all RSS readers will notify the user if there is any new entries in RSS. In this way, keeping update that is so easy instead of visiting their "What's News" page daily. Thus, I think RSS is essential for the kind of "What's News" Component
