Sass/Less Comparison

In this document I am using Sass's SCSS syntax. You can choose to use the indented syntax in sass, if you prefer it, it has no functional differences from the SCSS syntax.

For Less, I'm using the JavaScript version because this is what they suggest on the website. The ruby version may be different.

Add the following chunk to your existing ISC dhcpd.conf file.

if exists user-class and ( option user-class = "iPXE" ) {
    filename "http://boot.smidsrod.lan/boot.ipxe";
}
else {
    filename "undionly.kpxe";
}

I turned this gist into a "real" repository.  It is here:  http://github.com/pete/cats .


Here, placed side-by-side for comparison, are GNU's implementation of
cat, Plan 9's implementation, Busybox's implementation, and NetBSD's
implementation, Seventh Edition Unix (1979), and 4.3BSD.

For good measure (and because I suppose I am now committed to collecting
cats) also included are Second Edition Unix (in assembly) and Inferno's
implementation (in Limbo) for good measure.
