This is a short note I used at work to back up and restore the a MS SQL 2000 database. I have a database with the name abcengine running on a local SQL Server. I need to back up this datbase to a file, send it over to a remote SQL Server to restore it. There are two ways, which I’ve known, to back up a database. One of them is to use the Enterprise Manager to virsually back up, and another way is to use the Query Analyzer, writing the T-SQL code and run it....
A while back, I let my brother using my laptop while he was waiting for his to arried from online order. My laptop has dual boot: Windows Vista Home Premium and Debian. Of course, my bro would only use Vista. He created a folder with his name on the desktop for whatever purpose it was. Let’s called it: Evil.

I was attempting to install MS SQL Server 2005 Express edition without success on a computer run Windows Vista Business. There was an error message mentioned “…failed to compile the Managed Object Format (MOF)…” I’ve tried about five times with various solutions; still it didn’t fix the problem. As always, I found a working solution when I was about to give up on this installation. The problem was that the WMI repository was corrupted....
Just browsed around through Linux blogs and I came across an interesting tool “htop” posted at Linux and Open Source Blog. What is htop? It’s an interactive process viewer for Linux. It’s very similar to top, however htop enables you to scroll the list vertically or horizontally; as well as supporting mouse operation. To install htop on Debian/Ubuntu distros, run this command: $ sudo apt-get install htop For openSUSE 10.2, you probably can install it with Yast, but I like smart:...

The following is the command to compile dllsource.cs as a dynamic link library instead of the executable file: $ mcs /target:library dllsource.cs We can also specify a different name of the binary with the /out option. For example: $ mcs /target:library /out:mylibrary.dll dllsource.cs Finally, if we want to compile a souce which depends on a dll file, we need to use the /reference option. $ mcs example.cs /reference:mylibrary.dll Note: mcs is the mono compiler....
Recently I noticed that my prolog skill is becoming rusty for not putting it work for very long. For this reason, I’m going to randomly write some prolog snippets here and there. Let’s started with one predicate called “sum_list” which calculate the value of all elements in a list. `% The sum of all elements in list in prolog To run/test the above code, save it to a file called: list_sum....
