Apple’s first security update of 2009 for MacOS X may solve some security issues in the OS but it also seriously breaks Perl by installing old versions of some modules along with Perl. It looks like Perl works okay for things that MacOS X uses it for, but if you do development using it or have installed other modules than what it came bundled with you may find that it no longer works.

sudo is a command-line UNIX utility that allows you to execute a command as another user (most likely, the superuser). Usually you’ll use it to execute a single command:
or to start a shell:
sudo is similar to the
su command – the
su command also allows you to become another user (most likely root). The difference is that
su requires you to type the other user’s password.
sudo allows you to use your own password. The file
/etc/sudoers tells the system who is allowed to do what using the
sudo command. In a multiuser environment, this has the benefit of allowing multiple users to become root (or other users) without giving them the root password. Then you can easily revoke root privileges from a user if you need to without affecting the other people who may need to become root.
I don’t always have reliable online access when I’m coding – in particular, I was on a bus today for a couple of hours and didn’t always have Internet access. There are a couple of dashboard widgets for MacOS X which I found that helped out on the jQuery documentation front.
First, there’s http://code.google.com/p/jquery-reference/. This widget is designed for browsing… click around in it, but don’t expect to search it.
Then there’s also http://blog.medallia.com/2007/05/jquery_reference_widget.html. This widget is designed for searching – if you know what you’re looking for, you can find it quickly.
They’re both useful in different ways, and I used them both this afternoon.
