top and the bottom panels gone

So I booted my computer up this morning, logged in, and found that both the top and the bottom panels were gone. My desktop background is still there, but the panels aren't. When I do open a window and minimize it, it goes to nowhere. I have read a number of people with similar problems, but the solution is always "right click on the panel and add the window list." My problem is that I don't have a panel to right click on.I have Ubuntu 10.04(gnome desktop).
Any idea what happened or how to fix it?


I don't want to upset anyone but I have to make 3 problems for one of my exams.
I don't know how to work in Ubuntu and I really need to take this exam.

First problem:

Write a script that reads N elements of a vector and then calculates the sum of vector and their average.

Second problem:

To find all users' personal files, accessed in the last 7 days, the minimum size of 5MB. Display format will be:

File [filename] size [dim] KB
directory [path]
-> Has been accessed [nameOfDay] [DayNumber] [NameMonth] [Year] at [hh][mm][ss] AM /PM

And the third problem:

If you get to a computer that runs Ubuntu, and find an open session, find out fast whick user name has left open session, at which time he logged into the system and how much time has passed since then?

Thank you for your help!

Clock Issue

I am new to Ubuntu and just recently installed it on my Dell. I am having an issue with the clock time though. Everytime I shut down Ubuntu and open it again, my clock is three hours ahead. I change it back but it continues to do the same thing every time I shut it down and open it again.

Does anyone know why this is happening/how to fix it? Thanks!

requirements for 10.04

Am interested in trying Ubuntu - picked up a magazine on it with installation instructions and some of the requirements.
What I didn't see is how will this Ubuntu work if I upgrade the desktop.
I already have a dual boot - 2 separate hard drives. One runs XP and is dedicated to Adobe Photoshop. It will be upgraded as far as a version of Photoshop runs on XP which means more RAM and possibly a faster processor. This drive only connects to the internet to verify installations.
The other drive is Win 2000. This is the one I want to try 10.04 on.
Also, the magazine said nothing about hardware. This computer has an ethernet cable. What does Ubuntu do with stuff that's hard installed on the PC?
Need some answers before I try it.

Internet Problems

Ubuntu DNS Bug? Unable to query two name servers

I found one strange issue with ubuntu, can anyone suggest if its a bug or as designed?
If I have two nameservers in my resolv.conf, ubuntu only checks the first (and receives a ‘not found’ reply from there) and never goes to the next two nameservers. This behavior is very different from windows or other linux systems. When I switched the order of these nameservers the dns name I was having issues with worked and got resolved , but when that nameserver is not the first when it fails.

Has anyone faced any similar issues?

5 Firefox Add-Ons That I Suggest You Have To

All add-ons that I have reviewed here, I have been using for a long time. So indirectly I am responsible with what I write here :(
Therefore, what would I write here is really my opinion about these add-ons.

  1. DownThemAll!
    downthemall firefox add-on This add-on very useful when you download something from internet. Like other "Download Manager", DownThemAll! support segmented download, resume download and other feature such as:
    • Have all the files you want with just one click
      dTaOneClick downloads the files of a page using the last filters and the last renaming mask you set. Just go to download page that you want to download the content, and download it! Or you can right click on download link and select dTaOneClick!
    • Increasing download speed
      As I mentioned before, segmented download! It's increase download speed very significantly. On DownThemAll! official website, its said "This maximized use of bandwidth increases average download speed up to 400%." WOW!!! What is clear, I can assure you if you use this while on the LAN or WAN, the bandwidth will be yours for all: D

    And much more! It was only two advantages that I think could be considered for use. One thing that be the point is, you don't need to install it on your OS, because its an firefox add-on!
