strace: Practical Application Troubleshooting...
using the tool we all love to hate.

The Presentation will cover the Linux command line utility 'strace' and some of it's many uses. It will cover the basics of Linux System Calls and their use. The presentation will use examples throughout to provide genuine use-cases for the tool. The Presentation is focused on Practical Application Troubleshooting, it will not be an in-depth guide to the various System Calls. I will demonstrate many techniques that can help you to gain a deeper understanding of application execution flow on a Linux system.

If you are interested in the group, please sign up for the [SGVHAK mailing list] ( "SGVHAK Mailing List Sign Up"). We will continue to crosspost announcements to the SGVLUG mailing list. We are in the process of setting up a website or subpage.

Do you like working on hardware projects? Did you just get a Raspberry Pi/Arduino/Kinect with the intentions of doing something cool? Did you wish that there was a local meetup group where you can meet up with like-minded folks and actually make progress with your projects?

Come to our kickoff meeting on Thursday to discuss starting up this special interest group. Connect with your fellow hardware geeks and share some of the projects you've been working on. And if we can decide on a name for the SIG, we can set up things like a mailing list, website, and wiki.

We have been kindly granted access to a room at Caltech for this meeting only. It is a small classroom with about 30 student desks and a teacher desk. We will have access to a projector and power. There is an open wireless network.

Cloning SysAdmins with the Cloud and Juju

Its time to face the music: There's only a couple guys in Ops, and a lot of infrastructure to set up and it was all due yesterday. If only you could clone all the sysadmins of the world to get all of their expertise and know-how in deploying open source applications, you could actually get it done. Perhaps there is a way: Juju and Charms! Juju encapsulates services in a way that promotes sharing and collaboration the same way packages have done for open source software. If you are a sysadmin or a developer who is looking to get an infrastructure of databases, loadbalancers, and webapps up to speed rapidly, Juju may be interesting. If you are looking into deploying something massively scalable, like OpenStack or Hadoop, Juju is built to handle that task.

Speaker: Clint Byrum is a member of the Canonical Ubuntu Server Team, bringing years of Ops and Development experience in web environments to the task of making Ubuntu Server shine.

Build your own cloud hosted social network with Ruby on Rails, Git and Heroku

Ruby on Rails is an open source framework for developing database driven websites. Git is a source control management tool. Heroku is web hosting in the cloud. In this talk Homan Chou and David Ferril will give a brief overview of each of these tools and give a case study of a real working social network.
