File::ExtAttr

File::ExtAttr 0.04 is out. Changes:

0.04 2006-01-20
- (richdawe) Add Mac OS X support; thanks to Jonathan Rockway.
- (richdawe) Add a check to Makefile.PL for libattr's headers on Linux.
- (richdawe) Requirement on Perl 5.8.5 is spurious; remove it.

Hopefully this will get a little more exposure from the CPAN testers than the last release. That probably didn't get built by many people because of the Perl 5.8.5 dependency.

Perl

I released a pre-alpha of File::ExtAttr, a module for accessing files' extended attributes (arbitrary metadata in the form of key-value pairs). The API isn't stable and it only supports Linux. One Day it will support Mac OS X and the *BSD.

Logo for copy protection on audio CDs

I thought it was about time there was a logo to inform customers of the protection on audio CDs.

Perl

Last weekend I went to the London Perl Workshop at the City University in London. I really enjoyed the conference. The talks were well-delivered, interesting and reasonably varied. I particularly liked the way people just got on with it - JFDI! Inspirational. Last year's was a bit cramped, but the venue seemed to be just the right size this year.

Last night I gave a couple of lightning talks at Birmingham.pm:

• Extended file attributes on Linux

• Web 2.0 at London Perl Workshop

I've not done lightning talks before. They were fun to write and fun to give. Hopefully the audience enjoyed them too!

At some point in the hopefully-not-to-distant future we'll release File::ExtAttr. This will be a Perl module to provide access to extended file attributes (used for e.g.: ACLs). It's nice to be collaborating on open source over the internet again.

Music

Listening to some music off Magnatune. This is an online music shop with a business model I like. You can listen to full-quality previews before buying. Once you buy the music, you can do what you want with it. There's no DRM. Yay!

Sony rootkit / uninstaller

"More on Sony's DRM Rootkit" by Bruce Schneier
"Sony's Web-Based Uninstaller Opens a Big Security Hole; Sony to Recall Discs" by Alex Halderman and Ed Felten

Inflammatory comment: So it seems like the only secure way of getting music these days is to use P2P, since it's unencumbered.

I'm not advocating or condoning piracy. But way to go Sony on convincing people that DRM is in people's interests (as in: DRM guarantees revenue, ensuring Sony can support new artists, ensuring people get new music, etc.).

Blogged Down

So a while ago I reached the point where my own personal planet was completely overwhelmed by the number of blogs I was aggregating. I've been using PlanetPlanet to do the aggregation pretty successfully (using my FC4 rpms of PlanetPlanet).

So I had a look around at a couple of RSS readers. First I tried straw, which looked really good, but failed the "runs successfully" test. Next up was Liferea, which is what I'm using right now.

I have to admit I was a little sceptical of using a separate program. I also had a look at some Firefox plug-ins, which looked promising and probably offer a better interface for discovering and picking up new feeds. But I use Mozilla as my browser and mail client and I'm not ready to switch yet (I'm awkward like that).

Anyway, my personal aggregated planet combined with Liferea seems to be a pretty good combination.

Evolution

For a while I've wanted to search on Sender and Recipients simultaneously in Evolution, to follow a thread. Someone kindly provided me with a patch to do that:

Phishes, ahoy!

Today my bank actually sent me an e-mail. That's right, a non-phish. And it's about a prize draw for their Internet banking service. I mean, WTF?

This is an example of banks being unhelpful to their customers. If you want to help combat phishing, don't ever send your customers e-mail and tell them that you'll never send them mail. Don't muddy the waters by occasionally sending them e-mail.

Do banks actually care about helping their customers?

Auto-blackholeing zombies

A while ago I had the idea of having netfilter automatically blackhole any traffic from zombies. A module would automatically check Spamhaus's XBL and throw away the traffic. Or send RSTs.

A slightly more friendly alternative is to redirect HTTP traffic from that IP address to a web page explaining that the user needs to clean their computer.

I have no idea if this is possible with netfilter, never having played with it. I'm finding it hard to get free time to investigate this, so I'm recording this idea here for posterity.

"Agile Software Development In The Large"

I finally finished reading "Agile Software Development In The Large: Diving Into the Deep" by Jutta Eckstein, which I've been reading since April, when I bought it at ACCU 2005.

Mostly I bought it to find out more about Agile programming, but it seems jam-packed with sensible advice, like "Peopleware" by Tom Demarco. It's very readable, interspersed by useful real-world examples of how to apply the advice.

My only criticism is that I still have no idea what Agile Programming is. From that I conclude a few things:

1. Agile Programming isn't one thing, it's a collection of methodologies - Extreme Programming, Scrum, other methods. (Well, duh, I'm sure I knew that before I read the book. I guess I expected to find it was some other magical thing.)
2. I may have already been doing a number of the things that make up Agile Programming. Sprints seem familiar, although I don't think I involved customers to the extent required by Agile Programming methodologies.
3. I haven't had enough experience to really get this book yet.

Point 3 is the crux. Time to experiment a bit with it.

TV...

...or why I may finally get a TV. More4 on the free-to-view broadcast Digital TV is going to show the Daily Show with Jon Stewart. That guy is a legend.

pptpclient vs. kernel-2.6.13-1.1526_FC4

The latest errata kernel for Fedora Core 4 broke my PPTP VPN using pptpclient. I've done an updated kernel_ppp_mppe rpm that works with the new 2.6.13 kernel. Get it from my Fedora Core 4 area.
