Understanding Git
| Date: September 29, 2009, at 4:30 PM
|
| Presenters: Nelson Elhage (nelhage)
|
| Location: 4-231
|
| Notes: Understanding Git (slides)
|
| Abstract: Git is a free software distributed version control system originally written by Linus Torvalds for Linux kernel development. It is increasingly commonly used, and learning to use it can be greatly benefited by a little help from those who understand how to use it. This talk will provide a brief tutorial on how to use Git and a technical overview of how it works under the covers.

Invirt
| Date: October 6, 2009, at 4:30 PM
|
| Presenters: Evan Broder (broder)
|
| Location: 4-231
|
| Abstract: Invirt is the software behind XVM, SIPB's community virtualization hosting service. Since we launched less than a year ago, users have created over 400 VMs, of which about 200 are turned on at any given time. At this talk we'll be giving a whirlwind tour of XVM's infrastructure and architecture, including how the moving parts running on 7 different servers fit together. We'll also showcase a few aspects of Invirt that we think are particularly innovative. If you're interested in learning more about virtualization, helping us hack on Invirt/XVM (and we could always use more help), running your own install of Invirt, or just seeing a good case-study on building scalable systems, this should be a good talk for you.

Statistics and the Non-Conflict between Bayesians and Frequentists
| Date: October 13, 2009, at 4:30 PM

| Notes: Statistics and the Non-Conflict between Bayesians and Frequentists (slides)
|
| Abstract: I'll go over the building blocks of statistics and why you often hear about the conflict between "Bayesians" and "frequentists." Focusing on simple examples, I'll explain each camp and why I think they aren't really in disagreement. Hopefully we can get the audience shouting about this non-conflict. I'll also talk about some of my work on measuring the performance of confidence intervals and p-values, how you can make $800 million because of a lousy approximation, and "Why Most Published Research Findings Are False."
