Open Source Bridge

So your project needs a book? Do you write it yourself, or do you approach a publisher? This talk walks you through everything that factors into this decision providing real world examples of projects and companies offering open source books.

What OSS database to use is an important decision, but recently languishing in the shadow of the sexier "what framework should I use" talks - or underplayed as though the battle were only SQL v noSQL. If your understanding of data storage tops out at "Mongo is webscale" or "mysql + memcached = win" then this talk is for you.

The CoApp project is bringing real open-source style package management to Windows; this session demonstrates the basics of creating and consuming CoApp packages.

If you can't reproduce your work reliably then you can't maintain it. You may get by for a while with ad-hoc build/release/deployment processes, but sooner or later they'll bite you. We'll present a new practical approach to assembling both software products and installed systems, drawing inspiration from sources including the functional programming community, commercial software projects, large IT deployments, and Linux distributions like Debian. Slides available at http://apters.com/osbridge2011.pdf

Importing, managing, correcting, reprojecting and mashing up geodata with PostGIS and OGR

How to use Debian live build to create a specific live GNU/Linux distribution. It will be illustrated by these 3 live distributions: Clonezilla live, DRBL live, and GParted live, special live GNU/Linux distributions for system imaging/cloning, diskless linux, and graphical partition editor, respectively.

Data Science promises to transform ubiquitous and cheap data into insights with the potential for great social, scientific and personal value. I will provide a lightning tour of high level theory, concepts, and tools to extract knowledge and value from data.

ETL. OLAP. BIDW. ELT. M/R. MPP. Windowing. Matviews. Data Marts. Column Stores. Are you at sea in a tidal surge of arcane terminology, trying to cope with big data problems?

So often we’re solely focused on the performance of our production systems. When disaster strikes, your team needs to know when error conditions begin, where they’re coming from, frequency, and an indication of the last time they occurred. Parsing logs isn’t fast enough, and email can’t keep up or preserve metadata.

As the Internet world moves slowly towards implementing DNSSEC, this session aims to start at the basics of DNSSEC and goes on to discuss implementation details as well as best practices, some of the most common mistakes that happen during and after deployments and finally what’s in store for the near future.

ePUB is the open e-book standard. Building on previous open standards, the ePUB format allows for flexible and flowing documentation, perfect for viewing on a variety of devices where the forced page sizing of other formats fails. We'll crack open some ePUB files and take a look at the innards and then we'll check out some tools to make ePUB generation less painful.

Methods of communication are constantly evolving, and traditional phone systems can not keep up. Open source phone systems allow for infinite possibilities for customizing the way we interact with each other. This session will walk through setting up your own Asterisk IP PBX from bare-metal to making calls.

Lots of attention has been given to GPUs for speeding up certain types of computations. While GPUs are very well suited for vector operations, there are other things they are not so well suited for. FPGAs (Field Programmable Gate Arrays) are not used as widely yet, but they offer a much more flexible computing fabric than GPUs. You can implement a GPU in an FPGA, for example, or you could implement your own custom processor optimized for very specialized tasks. The barrier to entry can be high for FPGAs: how does a person with a software development background get started using them? And what about HDLs (Hardware Description Langauges) used to program FPGAs? What's the difference between simulation and synthesis? What kinds of tools are freely available? These are some of the questions that will be addressed in this session.

Leave rigid tables behind, and work with your data as a graph, using standard web data schemas.

Ganeti is a cluster virtualization management software tool built on top of existing virtualization technologies such as Xen or KVM and other Open Source software. This hands-on tutorial will give an overview of Ganeti, how to install it, how to get started deploying VMs, & administrative guide to Ganeti. The tutorial will also cover installing & using Ganeti Web Manager as a web front-end.

You’ll learn about the techniques needed to transform classes at runtime, adding new behaviors and addressing cross-cutting concerns. The presentation will discuss a new framework for this specific purpose, but also draw examples from the Apache Tapestry web framework, which itself is rich in meta-programming constructs.

More and more FOSS projects are benefiting from a formal design process. This is an opportunity to see accessibility as a design requirement and integrate into earlier stages of the project's cycle as opposed to the afterthought it often is. In this talk we will see what a design process that integrates universal design looks like, and open the floor to discussion about inclusivity in design.

Overview of Apache CouchDB, who is using it, and how you can too.

The bar to contribution in Open Source web development projects can be lowered through the use of devops tools and virtual machine technologies.

From the Browser to node.js all the way to the database you can use and share your JavaScript!

In this puppet show, a wise lion coaches an eager but inexperienced mouse through the process of normalization and (equally important) denormalization.

Django is a great web application framework that allows for rapid web app development out of the box. Since Mozilla picked up Django in 2009, they've started over a dozen Django-based projects. For these sites to scale to an international audience of millions of users, bells and whistles were needed that a stock Django instance does not offer. Playdoh combines the experience of these projects into a template that contains various fixes and add-ons to make professional Django apps fast, featuring aggressive caching, instant localization support, and bullet-proof security.

Improvements in Perl 5 over the past several years allow great programmers to do great things with less code. You too can turn your Perl 5 code from mere scripting into powerful, clear, and modern programming--with help from a few tools the world's best Perl programmers already know and love.

Everything you learned about database modeling is wrong. At least for document databases like CouchDB and MongoDB. Learn about these differences, the trade-offs, the use cases, and put it all in practice in a discussion about a real-life document database problem. Unlearn SQL habits and relax.

Are you tired of null pointer exceptions, unintended side effects, SQL injections, concurrency errors, mistaken equality tests, and other run-time errors that appear during testing or in the field? A compile-time tool named the Checker Framework has found hundreds of such errors. Oracle plans to include it in the Java 8 javac, but you can use it today to improve your code and avoid errors.

A deployment pipeline combines several development best practices, fully automated and taken to their logical extreme. The result is almost magical: changesets go in one end, and fully-tested software packages come out the other. We'll take a tour of the components of a deployment pipeline, with concrete examples showing how to use Hudson, Rake, and Puppet to deploy PHP projects.

Read the Docs is a documentation hosting site for the community. It was built in 48 hours in the 2010 Django Dash. In January 2010 it had 100,000 page views, and increases daily. I will talk about all of the code to deploy and run a sizable Django site. We will go through the highlights and interesting parts of the code, as well as some of the lessons learned from the site being open source.

In a world where Javascript is everywhere; your browser, server, database, mobile device -- you want and need code reuse to speed up development. In order to do this, you need to know that code works in all the environments you care about. Jellyfish is a node project focused on provisioning different environments and making it easy for you to execute your JS and get the results.

The traits of an 'open' dataset -- factors like accuracy, geographic scope and copyright entanglements -- shape the development process in profound ways. I'll share what I've learned building projects around heritage trees, public art and poetry posts in Portland, and extrapolate a blueprint for evaluating and planning open data projects.

Technical debt is something that most project teams or independent developers have to deal with - we take shortcuts to push out releases, deadlines need to be met, quick fixes slowly become the standard. In this talk, we will discuss what technical debt is, when it is acceptable and when it isn't, and strategies for effectively managing it, both on an independent and team level.

Tests are great - except when they aren't. Learn how to avoid writing tests that are more trouble than they're worth.

Learn to use simple natural language processing and graph analysis tools in Python and R to explore the structure of the dataverse. From Reddit to the USPTO to Google Books, come try some data hacks!

Why be locked into a cloud vendor? Shouldn't Cloud be Open Cloud and powered by Open Source software? Open Stack is a collection of open source technologies to deliver a cloud operating system. Learn about Open Stack and how to use it to deliver your own Open Source powered clouds.

What's going on in the mind of the user as they use your system? Did they choose it, or was it chosen for them? Do they like it or hate it? How can you tell? This talk discusses the types of users that exist, and their motivations.

Web frameworks have done a good job of organizing the server side code in our web applications. But that doesn't help with Javascript. RequireJS helps you solve this problem.
