Which is best? SQL Server vs Postgres

Rob Sullivan
Falling in love with the free spirit of Postgres Using the StackOverFlow datasets, we'll ditch all the drama of a Microsoft stack and convert from SQL Server to Postgres on Windows. Once we do that, we'll migrate our entire DB and Web App from Microsoft to Linux using Postgres and Mono with as few code changes as possible. Having the StackOverFlow dataset loaded into SQL Server and a mock StackOverFlow app in ASP.NET MVC3, we...

Temporal Data Management in PostgreSQL: Past, Present, and Future

Jeff Davis
Range Types and Temporal: Past, Present, and Future Range Types didn't exist before, why do we need them now? How do they work? Why is "Temporal" important if we already have timestamps? How do we apply these concepts before deploying PostgreSQL 9.2? What's left to be done, and what solutions are in the works? I'll be asking the audience these questions, so -- Err... I mean: I will be answering these questions during the talk....

Runtime Process Infection (part 1)

Shawn Webb
This presentation will instruct participants on how to inject arbitrary code into a process during runtime. Writing malware on Linux isn't an easy task. Anonymously injecting shared objects has been a frightful task that no one has publicly implemented. This presentation will show how and why malware authors can inject shared objects anonymously in 32bit and 64bit linux and 64bit FreeBSD. The presenter will be releasing a new version of a tool called libhijack. libhijack...

Managing FreeBSD at scale

Allan Jude
Detailed discussion of ScaleEngine's production implementation of puppet on FreeBSD to manage many heterogeneous servers across the globe, with 70+ servers at 26 data centres in 10 countries deployed in a number of different roles (Web Hosting Cluster, HTTP Accelerator, HTTP CDN, Live Video, On-Demand Video, GSLB DNS) our needs cover a large swath of the capabilities of any management system. It is common for sysadmins to jump straight to cloud providers if immediate scale...
