Use Image Magick to batch convert .png files to .gif

By Ammon | October 16 2010

I just checked, and W3Counter puts global Internet Explorer 6 usage at just 5.78%. This is a pretty good argument for not supporting it anymore with my websites, but I still do it. Maybe its just habit, or maybe its because I’ve become really fast at dealing with IE6 and its many deficiencies so its [...]

Imagemagick: use montage to proof images

By Ammon | June 14 2010

The following command will create an image called montage.png that is a collection of all the .png files in the current directory. Images larger than 150px on a side will be resized, but aspect ratio is preserved. The images are separated by a 2px offset. $ montage *.png -geometry 150×150\>+2+2 montage.png

Image Magick: Resize a batch of images so they all come out square, and preserve filenames

By Ammon | April 21 2010

The following command will shrink all .jpg’s in the current directory that are larger than 500px and center them on a square 500x500px canvas. Since the aspect ratio of the original images will be preserved and not all of the originals are square, the left over space will be filled with an off-white color. All [...]

Use source to import large .sql files

By Ammon | April 1 2010

Its true, don’t waste your time with strange scripts and such if you’re trying to upload an .sql file that exceeds the limit. Just give up and use source. Note: don’t be confused that I don’t capitalise my MySQL commands. Its my silent protest against standard MySQL syntax: I think capitalising commands you have to [...]

The better way to install LAMP on Ubuntu Karmic 9.10

By Ammon | March 29 2010

All this comes from here: https://help.ubuntu.com/community/ApacheMySQLPHP In the teminal: $ sudo tasksel install lamp-server $ sudo apt-get install phpmyadmin $ sudo gedit /etc/apache2/apache2.conf Add the following to the end of this file:  “Include /etc/phpmyadmin/apache.conf” Edit the /etc/php5/apache2/php.ini file and increase the memory_limit value. I used 64M, but that may be overkill.
