Use sudo Without a Password on Your Mac

Saturday, November 8th, 2008

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:

sudo dmesg

or to start a shell:

sudo -s

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.

Offline jQuery Documentation for MacOS X

Thursday, October 30th, 2008

I’m rewriting UVFood to use jQuery instead of Prototype. I’m liking jQuery quite a bit and my code’s looking much better (and tighter).

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.

Apple’s iPod Event on September 9th

iPods

Apple loves Tuesdays. Tuesday is when new music and DVDs come out, so Tuesday is when music and movies show up in the iTunes Store. Apple also has a tendency to release new products on Tuesdays. And they often have “special events” on Tuesdays as well.

Tuesday September 9th 2008 (today as I finish this; I meant to get this out sooner) is a special Apple event called “Let’s Rock” - although they haven’t specified, it’s clearly related to the iPod/music side of their business. And it follows a pattern they’ve established over the last few years of announcing new iPods in the fall. This gets them out in time for the Christmas season.
