Today I gave a presentation at UNAM's 2011 Computer Security Conference in Mexico City. Below you will find my presentation (done using prezi.com, follow this link if you can't see it below).

I'm attending UNAM's computer security conference, giving a talk as well. Some photos from the event (will be updated throughout the day)

Nyamulagira, which generally erupts every two years, rumbled to life at 8:06 p.m via news.nationalgeographic.com Must be an amazing sight.

via theinspiration.com One time on a plane from Brussels to Chicago, I was trying to make space in the overhead for my backpack, by moving a large bag with a flowery stamped design. A large tattooed, biker-type guy across the aisle says to me: "please be careful, I'm transporting a china set in there". Never judge people by their appearance :)

Quadrocopters are really getting popular for research, and for a reason - they are seriously cool. Arms / grippers have already been used on them: They can also do ball jugling: Have precise movement control: And do mapping: Tip of the rotor blade to Axel Tanner for sending me these.

via theatlantic.com Wow.

I’m doing some cleanup and reorganization, and captured my current app setup as a reference point. Here they are. Quick note: The first screen is my most-used apps (some are going out now, like 2Do which I've never liked too much, but was the best way to sync tasks with Outlook, which I'm no longer forced using). Second screen is all my folders. Third and fourth screens are my girls' screens, with the games they use when they borrow my phone.

CFEngine is both the oldest and the newest of the popular tools for automating site administration. Mark Burgess invented it as a free software project in 1993, and years later, as deployments in the field outgrew its original design he gave it a complete rethink and developed the powerful concept of promise theory to make it modular and maintainable. via radar.oreilly.com I contributed to this article by Andy Oram on CFEngine 3.

Let's talk about some of those secret features you may not know about. via github.com Nice article about some lesser-known GitHub features.

A new version of CFEngine 3 Nova was released today, and to go with it, there will be a free webinar called "Introduction to CFEngine 3 Nova" on November 2nd. It will be presented by one of the members of the core CFEngine team, and it will be a great opportunity to learn more about the new and improved capabilities in this release. If you are interested in CFEngine and maybe thinking of going the commercial route, or you need more information to decide, make sure to attend!

The tools that Dennis built — and their direct descendants — run pretty much everything today. —Brian Kernighan via nytimes.com Nice article about Dennis Ritchie.

via kottke.org WHOA, WHERE THE HELL DID THAT GUITAR NOISE COME FROM??!

via vimeo.com Nice video.

Today I have two big announcements to make. First, as of this week I have a new job, I am now working with CFEngine AS, the company that develops and maintains cfengine. As you know if you read my blog, I am a big fan of cfengine. It is a mature and able tool that provides extreme flexibility and power to system administrators. The company is full of energy and with very interesting projects to make cfengine even better and more popular than it is today.

Dennis Ritchie passed away last weekend. He was one of the great minds in systems research and development, father of the C programming language, and one of the big contributors to Unix, both of which power the Mac on which I'm typing this, the iPhone on my desk, the Windows machine I use at work, the servers on which this blog is hosted, and much of the infrastructure both you and I use to connect to it.

Farewell, Steve. Thank you for all you did for the computer industry, for design, for music, for telephony, and for so many other aspects of our lives. You will be missed.

A few days ago I learned through Spaf that Gene Schultz had had a severe accident and was hospitalized. Later we learned that the accident was apparently caused by an earlier stroke that went unrecognized. Yesterday, October 2nd, during the afternoon, Gene passed away. I met Gene about 15 years ago while I was a grad student at Purdue. I met him initially at a couple of conferences, and later while he was visiting Purdue for some time.

via gizmodo.com This is the stuff of Sci-Fi movies. Amazing.

via slipsum.com Awesome.

via blogs.discovermagazine.com Amazing illusion.

via youtube.com This is making the rounds, so I might as well contribute. Beautiful (and maybe not so hard to do - it's much like a dot-matrix printer, but printing from bottom up). I saw one of these a few years ago at the Motor Show in Geneva (at the Jeep stand), but it was much lower resolution and much less creative.
