Today’s spam

I noticed this in my inbox today, it got past the spam filter:

“If all you dream about is pain relief, why are you still living? It is not real life!”

It’s fun to interpret it in different ways. And it’s kind of shocking as an advertisement.

The reality of AI

I think this is rather amusing.

If you go to the AI-class FAQ the first thing you will see is:

if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases

This suggested that I wanted a .bash_aliases file for my aliases, so I set one up:

jj5@sixsigma:~$ cat .bash_aliases
alias home='cd ~'
alias jj5='cd /var/www/'
alias profile='cd /var/www/'
alias chomsky='vim /var/www/'
alias henney='vim /var/www/'
alias lakoff='vim /var/www/'
alias norvig='vim /var/www/'

This is my basic “CMS” system for

I’m a little embarrassed to say that I only looked this up for the first time today. Although, I’ve been programming in JavaScript for so long that I must have known this years ago, but “forgotten” as I haven’t done much JavaScript programming in the last few years. Hey, at least I retained that niggling feeling like I had to look that up!
