Best Video Downloader Addons in Firefox

Written by Mahmoud Ahmadinejad on 3:31 PM

I've been trying dozen of addons for video download management. But it is sometime there is a video that won't downloaded. UnPlug was nice with its integrated button on the browser. But i need something that is quickly find where the video location is and download it directly to my computer as fast as it could. MediaPirate is another good one, but it's not simple to me. It opens a new tab with the MediaPirate website where you can find the download link.

When i dumped into mozilla site, i found that Video DownloadHelper was at the top in popularity. Just direct your Firefox to this and see how popular it is. It download videos from many sites in seconds. Great, this is what i was looking for. Below is the screenshot on my computer :






Safe Computing against your child : Linux might be the answer

Written by Mahmoud Ahmadinejad on 1:47 AM

Imagine that you got three lovely cute and growing children, and you got only one PC at your home. You went to your office as usual and went home late at night. You turn your PC on. Logging in to your account and suddenly.... Hey..!!! Where is my data? Where is my MS Office?. Your data is lost and your MS Office is uninstalled. By who? Needles to say, your children did the job. They accidentally erased your files and uninstall your software.

That is just and illustrated story if we are in the Windows world. Since it has no protection against file rights. Files is just files. They just wrote to your hard drive with some information like its size, last accessed time, and the type of that files. In Unix and Linux world, all hardware and software are treated as files. Look under directory /dev and you will see huge list of hardware list over there.

What about protection? In Linux world we got something called file permission. It ensures that only the right user can read, write, or execute the files. Give an ls -l command in the console and it explain a lot.

Here is the output on my console :

salon@Presario:~$ ls -l
total 835508
-rw-r--r-- 1 salon users 539079 2007-11-11 20:14 118262253_fb1db4700e_b.jpg
-rw-r--r-- 1 salon users 109954 2007-11-07 10:41 22030-Ubuntu-Smooth-Splash.tar.gz
-rw-r--r-- 1 salon users 52973 2007-11-07 10:31 36907-Blu.xpm.gz
-rw-r--r-- 1 salon users 212215 2007-11-04 23:46 4x4offroads-12-1280.jpg
-rw-r--r-- 1 salon users 235112 2007-11-04 23:48 4x4offroads-16-1280.jpg
-rw-r--r-- 1 salon users 217260 2007-11-04 23:48 4x4offroads-17-1280.jpg

Notice that rw-r--r-- sign. What the hell is it? For easy understanding read carefully below :

rw- means that the owner of the file, in this case salon has the right to read and write the file
r-- means that all of the groups member, in this case users group, can only read the file
r-- means other than the owner and the groups members can only read the file

You can also modify the bit by using chmod command. Issuing command chmod 700 (somefiles) would change the permission so only the owner of the files can access it. But i don't like back to DOS world by typing those commands. Easy, just fire up Nautilus and right click to the file you want to modify. Choose properties and click permission tab. Change it the way you like.

So now you just change the permission of your data folder and you don't have to worry again. Good Luck.




Everyday Searching

Written by Mahmoud Ahmadinejad on 4:51 AM

Most of all are addicted to this famous, neat and clever search engine. Yup, i'm talking about google. But we seldom to realize that there are hundreds of search engine out there. Many of them specialized in specific topic too. After some googling around i found these search engine are useful. And i hope it would be useful for all of you too..

Yahoo!
This is the oldest web directory on the net. With its large database, it also acts like search engine too.

Dogpile
All the best search engines piled into one. That's it.

AltaVista
Find webpages, audio, video, images and news easily. You can search to a specific country like in th US, Australia, or Austria. Currently there are 28 countries available for searching.

Windows Live Search
Another Microsoft product. Find feeds, news, images and webpages is easier than ever if you use such windows version. It integrate nicely on internet explorer. Windows and Hotmail users should use this page as default page on their browser.

Zuula
Fill your search query and your search result will displayed in 8 search engines tab. You can customize your search result tab. Available tabs are Google, Yahoo!, MSN, Mojeek, Accoona, Alexa, Exalead, and Gigablast.

Mamma
Like the ordinary search engines but with yellow pages and white pages search addition. Very nice.

Ask
Lot of features. You can find city map, video, news, webpages, and shopping products. Changeable skin of its front page makes searching is fun.

WebCrawler
Same like Zuula, but i prefer Zuula.

Netscape Search
Netscape users? Go there.

Clusty

Complete news, web portal and search engine.

MozDex
An open source search engine with Dmoz directory database

KartOO
KartOO is a metasearch engine with visual display interfaces. When you click on OK, KartOO launches the query to a set of search engines, gathers the results, compiles them and represents them in a series of interactive maps through a proprietary algorithm. Funny but still useful though.

Kanoodle
Sponsored Pay-Per-Click search engine. The result still accurate and comprehensive.

Hey !! I can see what inside that ISO's !!!

Written by Mahmoud Ahmadinejad on 4:39 AM

I can't find any solution to see what inside of ISO file until i know the power of "mount" command. Simple tips does magic !!! We used to burn the ISO or used some burning tool like Nero or xCDroast in order to know the content of the image. With this little command you can mount your ISOs and place to anywhere you want, in flash drive for example. Here is the trick :

  • Log in as super user ( su ) or use sudo command
  • Create a mount point eg: mkdir /mnt/iso
  • Issue this : mount -t iso9660 -o loop .iso /mnt/iso

That's it !!! Explore your extracted ISO in /mnt/iso with nautilus ( if you use Gnome ) or Konqueror / Dolphin ( if you use KDE )

Tired of those typing commands? try Kiso , a nice GUI tool to create, edit, and see your ISOs

Creating a swap file

Written by Mahmoud Ahmadinejad on 9:16 AM

Sometimes there is a case you can't make a swap partition in linux. Perhaps you've got a tiny size partition on your linux box because of that greedy vista in size. Now we're going to make just a swap file, like windows do.

Swapping on file is easy, but it has one lack. It is slower than swap partition. But if don't care about the calculation, read on.

First, make a file on your own. 256 M, 300 M, 512 M or whatever. Feel free to decide.

sudo dd if=/dev/zero of=/mnt/500Mb.swap bs=1M count=512


a little explanation : if means input file, since we create a file from nothing then we look for zero device under directory /dev . While of means output file.

format the file as a swap filesystem by using command :

sudo mkswap /mnt/500Mb.swap

That's it. You already have an active swap filesystem. Issue a free command if you find yourself curious.

One last trick, in order your linux automatically read it at boot time is to put a line in your /etc/fstab file.

gksudo gedit /etc/fstab ( use your prefered editor )

add this line below to your /etc/fstab file

/mnt/500Mb.swap swap swap defaults 0 0
