There are some replacements for Visio such as Kivio and OpeofficeDraw. I tried them, but I picked Dia. Firstly, it got most of the whole set of Visio objects. Moreover, the interface is the simplest one. Those are the reasons I like it.

At the website of OpenOffice, that is only providing RPM. Ununtu doesn't support that, and dapper has not version 3.0 yet. So it needs to do manually.
1. Go to http://download.openoffice.org/other.html
2. Download Linux DEB.
3. Untar the package.
4. Go to ./DEB

Note that: if you have installed the previous version of OpenOffice, please remove that. Unless dpkg will generate an error message to tell you the packages have the conflicts.

I am helping my uncle to improve his computers. He told Deleted items in Mapped Network Drive will not go to Recycle bin. If he deleted an item in a mapped network drive, he will not able to recover that in his Recycle bin. Today, this is the frist times, I realized that is a problem. I believe network drive is not for the user to do the daily operations, that is for backup and sharing the documents. You should not move those files around, so that is rare to delete the file.

What is DML?
DML is "Data Manipulation Language". Simply, that are included "select","insert", "update" and "delete" in SQL.

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.
