sudo apt-get install rox-filer

HIV/AIDS seminar in my campus

I just want to post picture from the HIV/AIDS seminar in my campus. So I can do my part in fighting the spread of the desease.

PS: click the picture to enlarge

just for the record though

this section in my writing consists of some simple but important information about ubuntu, So I am compiling them here.

if you use ubuntu, you should know there are three menu, ie. applications, places and system. Now I want to add my folder under places so as to open my folder quicker. to do this though is simple, you just have to open nautilus and click on bookmarks and choose your specified folder. And the folder of your choice will appear under places.

you should know the command fdisk -l, it is the command to show your partitions. But have you ever wondered why the command can only be run as root. Well it’s because the -l option to fdisk requires read access to your disk devices in the /dev directory. These have rw permission granted for the root user and the disk group. If you put the user running the script in the “disk” group in /etc/group, then you will be able to read the partition table. Be aware that the user will now have read/write access to all your disks which is a potential security issue.
So if you want to know the partition as a normal user you just need to use the following command

jacobian@jacobian-laptop:~$ cat /proc/partitions
major minor  #blocks  name

   8     0  117220824 sda
   8     1   37415385 sda1
   8     2    6097920 sda2
   8     3          1 sda3
   8     4   35840983 sda4
   8     5     955836 sda5
   8     6   36901273 sda6

and for the last info in this section, I want to talk about terminal. When you open the terminal it always show this symbol “~”. have you ever wondered what that’s symbol means?

~/ is short for the /home/username directory

so if you have that symbol in your terminal that’s means you’re in your home directory.

how to change date format in evolution

I always use evolution to download my email, but recently I get bored by the time setting that always use am/pm.
So I was thinking how I could change the time format into 24 hour settings. Well, after much of hard work I finally knew how to do it.
you just have to type this command into your console

sudo update-locale LC_TIME=en_ZA.UTF-8

and try to type this command in your konsole and it should show the following line

jacobian@jacobian-laptop:~$ cat /etc/default/locale
LANG=”en_US.UTF-8″
LC_TIME=en_ZA.UTF-8

then you have to log out and log back in for the changes to take effect. And you will see that your evolution now uses 24 hour settings

PS : it also changes the all time format into 24 hour setting in your computer.  

tools to see system details

if you want to know how to see system details like what kind or how much ram is installed, video card, sound card and so on. Then you can use sysinfo or lshw. You just have to type it in your konsole and it will show the details of your system. If you prefer the applications though you can install the software to show your system details. Below is the software that I recommend for you to use.

gnome-device-manager
kde-hal-device-manager
hwinfo

opera seminar in my campus

well, opera just held a seminar in my campus. It clearly gave me an idea of the perspective of the web. Such as the introduction of WSC (web standard consortium).  If you want to make a web, you should take a look into WSC before you make a web. Because it will make easier for other people to browse your website. At the seminar we also talk about HTML 5, SVG and the introduction of new opera mini. I just think opera really did something remarkable by bringing its users a new innovative technology. It’s just too bad opera is closed source though. hehe…
