These are some unix shell (bash/ksh/tcsh/...) tricks I've collected. I'm placing them here because, typically I'm away from my personal machine when I most need one.

    function fps {
        (( $# )) &&
        ps -aux | sed -n "1p;/_µµµµ_µµµµ_fps_µµµµ_µµµµ_/d;/$1/p" ||
        echo "Usage: fps <search string>"
    }

Interesting button on an order form I saw: It deals with the issue of multiple clicks on a submission button by changing the name when the user first clicks on the button and ignoring additional clicks.

<script type='text/javascript'>

document.write("<INPUT TYPE='button' NAME='Submit'
   VALUE='Submit Secure Order' onClick=\"if(this.value ==
   'Submit Secure Order') this.form.submit();
   this.value = 'Working...Please Wait.';\">");
// -->
</script>
<noscript>
<INPUT TYPE='submit' NAME='Submit' VALUE='Submit Secure Order'>
</noscript>
