Ray is an OpenBSD developer who uses Subversion by day, CVS by night. Taking the phrase "complexity is the enemy of security" to heart, he believes that the beauty of UNIX`s security is in its simplicity.
]]>Security policies are a key component in protecting enterprise networks. But, while there are many diverse defensive options available, current models and mechanisms for mechanically-enforced security policies are limited to traditional admission-based access control. Defensive capabilities include among others logging, firewalls, honeypots, rollback/recovery, and intrusion detection systems, while policy enforcement is essentially limited to one-off access control. Furthermore, access-control mechanisms operate independently on each service, which can (and often does) lead to inconsistent or incorrect application of the intended system-wide policy. We propose a new scheme for global security policies. Every policy decision is made with near-global knowledge, and re-evaluated as global knowledge changes. Using a variety of actuators, we make the full array of defensive capabilities available to the global policy. Our goal is a coherent, enterprise-wide response to any network threat.
Biography
Matthew Burnside is a Ph.D. student in the Computer Science department at Columbia University, in New York. He works for Professor Angelos Keromytis in the Network Security Lab. He received his B.A and M.Eng from MIT in 2000, and 2002, respectively. His main research interests are in computer security, trust management, and network anonymity.
]]>Ivan Ivanov is generally interested in Version Control Systems since his student years in Sofia University, Bulgaria, where he set up and maintained a CVS server for an academic project. When Subversion became a fact and proved to be "a better CVS" he researched it and last year deployed it for his NYC-based employer Ariel Partners (http://www.arielpartners.com/). He intergrated the Subversion repositories with Apache Web Server over https to enable a reliable and secure way to access them from any point.
]]>First and foremost, I would like to thank the unique presentation styles of Dick Hardt and Lawrence Lessig for inspiring me to create this presentation.
The following videos were created by exporting the original Keynote presentation slides into QuickTime video, then manually synchronizing them using iMovie HD with the audio recordings captured by Nikolai Fetissov. They were then exported into QuickTime, mpeg4 (H.264/AAC), and iPod movie formats. If you are having difficulties with the MP4 copy, and are unable to view QuickTime movies, please contact me and I'll try to assist.
]]>The first half of the talk will introduce Varnish and present some of the novel features it brings to the business of web-serving.
The second half of the talk, using Varnish as the example, will show ways to get the most performance out of modern hardware and operating systems.

Ty and Theo really do go to a (very specific) bar and discuss what is going on in the project, and then try to find a theme that will work...

]]>While tests of the release binaries are done by developers around the world, Theo and some developers from Calgary or Edmonton (such as Peter Valchev or Bob Beck) test that the discs are full of (only) correct code. Ty Semaka works for approximately two months to design and draw artwork that will fit the designated theme, and coordinates with his music buddies to write and record a song that also matches the theme.
Then the discs and all the artwork gets delivered to the plant, so that they can be pressed in time for an official release date.
This release, instead of bemoaning vendors or organizations that try to make our task of writing free software more difficult, we instead celebrate the 10 years that we have been given (so far) to write free software, express our themes in art, and the 5 years that we have made music with a group of talented musicians.
OpenBSD developers have been torturing each other for years now with Humppa-style music, so this release our users get a taste of this too. Sometimes at hackathons you will hear the same songs being played on multiple laptops, out of sync. It is under such duress that much of our code gets written.
We feel like Pufferix and Bobilix delivering The Three Discs of Freedom to those who want them whenever the need arises, then returning to celebrate the (unlocked) source tree with all the other developers.
