CSS opacity

Part of CSS3 - good for transparency on solid colour:

div.transparent {
    filter:alpha(opacity=25);
    -moz-opacity:.25;
    opacity:.25;

    background: #000;
}

1. This is the one for IE6
2. Legacy Firefox
3. Everyone else

Note: everything in the element is opacified, if you just want it on the background you'll need to float the foreground stuff on top.

User management

1. /usr/sbin/useradd -m -s /bin/bash user
   

2. /usr/bin/passwd user
   

3. /usr/sbin/visudo
   

   or

   /usr/sbin/usermod -a -G wheel user
   

sudo if you don't have su.

phpMyAdmin import from mysqldump

PMA (2.7 at least) cannot interpret /* */ comments. I hate it so much.

If you only have access to mysqldump at the export end and PMA at import, use --compact to strip the extra gear.

Javascript form submit

You can use Javascript to form.submit() on any visible element in DOM, but just remember to return false; after. If you're clever enough to have used an anchor, it will form submit and then follow the link - but not always in the same order. About 1 in 10 will follow the link first, then submit.

Advice: return false(), don't fill in the href, or just don't form.submit() on anchors.
