How to Resize Multiple Images in one Click in Ubuntu

Rajesh — Sat, 29 Jan 2011 09:24:38 +0000

Yesterday I went to Nassocom Emergeout Conclave for Startups, I clicked almost zillions of images and today when I tried to upload them in Facebook it gave me tough time cause of huge size so I thought lets resize it but there were so many images which would take me ages. When I Googled I found following method to resize multiple images in one go.

Here is an awesome way to resize zillions of images in one go-

1. Install imagemagick from Ubuntu Software Center
Or, in the terminal:
sudo apt-get install imagemagick

2. Put all your image files in a single directory/folder.

3. Open a terminal and go to this directory/folder:
cd

like I put my folder (named ”small”) in desktop so you can type

cd ~/Desktop/small

4. To resize all your images enter following command.

example – With following command, all of the images will be reduced to 50% ratio.

mogrify -resize 50% -format jpg *

Where -format jpg specifies: the resultant format will be JPG.

You can also specify width and height by the following command:

mogrify -resize 800x600 -format jpg *

Ubuntu Grub – Error: No such partition, Grub rescue

I have got Windows 7 and Ubuntu 10.04 LTS Lucid Lynx as dual boot, yesterday much awaited Ubuntu 10.10 Maverick Meerkat was launched so called the perfect 10, I was so excited to try my hands on it, I tried to upgrade through Internet as they have recommended on the site but my net connection is so slow that it was taking ages and I was getting impatient, then I downloaded the ISO image file and burnt on CD and try to upgrade it but it didn’t work.

Later I made up my mind that I’ll format the partition by login through Windows and install fresh Ubuntu installation, everything went smooth but when I restarted after installation it showed black screen with “Grub – Error: No such partition, Grub rescue” Damn, It gave me tough time to fix it I tired to reinstall Ubuntu three times but it didn’t work, later I followed following steps -

1. Booting from Live CD
2. Clicked “Try Ubuntu”
3. Go to Terminal or Crtl+Alt+T
4. sudo fdisk -l

You’ll get something like following screen

5. See where your Ubuntu installed, In my case it is on sda8, so that is the one you want to mount.

6 . Now on terminal type following to mount your right drive

sudo mount /dev/sda8 /mnt sudo grub-install --root-directory=/mnt /dev/sda

7. Once you restart you’ll find your boot loader screen

8 Enjoy

UltraSurf for Ubuntu Linux and Mac

Yesterday I installed Ubuntu Linux OS, everything went smooth, it hardly takes few minutes to install Ubuntu. Later I installed Wine to run Windows apps (Wine is an Open Source implementation of the Windows API on top of X and Unix). First I tried to run UltraSurf cause without it I can’t even able to breathe coz our network pipeline is so much choked with firewalls and censorship I can’t even check my mails on Gmail.

So here is easy steps to run Ultrasurf in Ubuntu and Mac

Ultrasurf for Ubuntu Linux OS

1. Install Wine

http://www.winehq.org/

2. Download the necessary dll files
mfc42.dll
msvcp60.dll

Note: you can easily find them by Googling but when I downloaded from a site and used them it showed following error:

“The ordinal 6880 could not be located in the dynamic link library MFC42.DLL”

so my suggestions is to copy them from your windows operating system from file location ->C://windows/System

3. Copy the two dll files to
~/.wine/drive_c/windows/system
~/.wine/drive_c/windows/system32

Note: if you go to file system and type ~/.wine at location bar then your hidden wine folder will get open then you can find above folders for pasting your necessary dll files.

4. Now run latest Ultrasurf and make sure settings like following screen shots.

Note: Goto options-enable Do not use IE option, set your networks proxy setting and then exit

5. Goto system-preferences-Network Proxy, Change your system proxy address to 127.0.0.1 and port to 9666

6. Now run Ultrasurf once again and enjoy the freedom

Note: while running Ultrasurf in Ubuntu it takes sometime cause it process through wine, just have little patience if it ain’t run.

Ultrasurf for Mac OSx

Just install the wine for Mac version and follow the above steps.

Good news Ultrasurf is much faster in Ubuntu than windows.
