The slides are online:
cplug_dropbox_112009_001-001

I was surprised that no one had heard of Ubuntu One even though quite a few people in the room were running Ubuntu 9.10.

That’s cool, because I’ve had some issues in the past with USB drives grabbing different device names than I expected. Using a truly unique identifier (or at least one that’s unlikely to be duplicated) such as a UUID helps out with that.

So how do you find the UUID of a device? Easy! You can either use:

root@europa:/root# blkid
/dev/sda1: UUID="3f467d1c-12bd-459e-be63-20e313faad88" TYPE="ext3"
/dev/sda5: TYPE="swap" UUID="cfe7d582-aa62-469b-8f4f-40927d013748"
/dev/sdb1: UUID="da488135-3744-487e-89e2-4898653db209" SEC_TYPE="ext2" TYPE="ext3"
/dev/sdc1: UUID="d438941d-e928-4ec1-9b96-eead147cd23e" TYPE="ext3"

Or if you need to find the UUID of a specific device, you can use this:

root@europa:/root# vol_id -u /dev/sdc1
d438941d-e928-4ec1-9b96-eead147cd23e

Copy and paste the UUID into /etc/fstab, add your mounting options, and you’re done.

Tickets are only $34.99 and give you access to all three conference tracks (21 speakers), breakfast, and lunch. Pretty good deal for a fun day. It’s also a great way to network with people, which is never a bad thing in a tight economy. :)

You can register at cposc.eventbrite.com and check out all the details at www.cposc.org.

Hope to see you in October!

Some of the slides that make use of build-in/out transitions exported to single images, so it doesn’t show each step. For example, in the Web Frameworks slide I included shout-outs to Rails, Django, Merb, Pylons, and TurboGears… but you’ll only see Rails.

If I get motivated, I’ll export it to Flash and upload it.

It will take place on Sunday, October 19th at the ITT Tech campus in Harrisburg, PA.

We have a date and a venue, so now we are currently looking for interesting speakers. I’d personally like to line up some more cool Python related talks (especially Django/Pylons related ones). If you would be interested in speaking, or know someone else who might be, please contact us.

More information is available in the announcement post and the Call for Participation page. The deadline for proposals is July 11, 2008.

Thanks!

Come on, admit it. That’s cool.

The slides were done in Keynote, so the images leave out some of the screenshots of the Openfire admin interface, but you’ll get the idea.

Enjoy!

I did the DenyHosts one, and you can check out the slides online. Seemed to go pretty well, with lots of questions and discussion after my talk. Definitely an interesting app for being so simple.

DenyHosts talk

For reference:

europa /var/log $ wc -l /etc/hosts.deny

Nice.

Although this time there will be no DoS attacks allowed and there will only be one target box, so you shouldn’t have to worry about player vs. player attacks… hopefully. :)

Well, it looks like things are starting to take shape! After an initial post on the mailing list, he has about 13-15 people signed up. The date/time are still TBD, but I know that I’ll be there no matter when it is.

Sounds like fun!
