laws of computer programming

• any given program, when running, is obsolete.
• if a program is useless, it will have to be documented.
• if a program is useful, it will have to be changed.
• any program will expand to fill all available memory.
• the value of a program is proportional to the weight of its output.
• program complexity grows until it exceeds the capability of the programmer to maintain it.
• make it possible for programmers to write in english and you will find that programmers cannot write in english.

// Must install ImageMagick first
http://www.imagemagick.org/script/index.php

//This compresses a jpg with no visible loss of quality. Add in your own file names for target.jpg and result.jpg
convert -strip -interlace Plane -sampling-factor 4:2:0 -quality 85% target.jpg result.jpg

// This does the same as above but to an entire folder (will overwrite original files):
mogrify -strip -interlace Plane -sampling-factor 4:2:0 -quality 85% *.jpg

//This does the same thing but to all subfolders as well (Be careful with this one it will overwrite all original files)

"A little bit of slope makes up for a lot of y-intercept"

01/13/2012. From a lecture by Professor John Ousterhout at Stanford, class CS140

Here's today's thought for the weekend. A little bit of slope makes up for a lot of Y-intercept.
