Object oriented programming - Objects and Classes [C++]

Posted 11-15-2011 at 03:02 AM by Aquarius_Girl
Updated 06-12-2013 at 12:31 PM by Aquarius_Girl

Object oriented programming is all about representing the parts of
the problem statements as `objects` and having them interact with
each other (by calling function(s) of the object in question).

Every object has a type. The type of an object is often called a
`class` in object oriented programming. The class contains the list
of characteristics of the object and the functions which the object
is capable of performing.
We can have many...

Almost but not quite qbasic.

Gosh I wrote so many programs in Quickbasic, I just hated to give them up. I looked around for a clone of Quickbasic and found Freebasic. I write a lot of my home automation routines in Freebasic now. So easy to control the parallel port compared to everything else and you do not have to have any special libraries other than the original libs to install the program. I have come up with at least on Debian a routine to install Freebasic. Tried it on Ubuntu 10.05 and Debian squeeze.

I have been cramming C++, MySQL, and recently I developed my first X-Window application using QT4. Now that I got a fair idea about the basics, it is time to jump into deep waters, and start programming like I used to in VB. I think that is the...

Merging two log files

Posted 11-14-2011 at 04:52 AM by zhjim

Today I needed to merge two log files in cronological together. Heres my way about.

copy the two files to one host. (scp file name@server:~userhome
get the hostname infront of each line. (sed -i s/^/hostname/g first_file; ...)
cat ./first_file ./second_file | sort -k 3 > ./new_log

-k in sort stands for key. In my turn the datetime was the third field.

Improvements:
Get some color into the diffrence hostsnames.
