Hacks track

Tinkering, experimenting and bending the rules to make hardware and software do what we want.
Hacks are clever. They break the rules. They force the available material into doing what you need or want. Some hacks are illegal, and some just make you proud and embarrassed that it worked. Sometimes a hack is the only way. Show the world how you make your hardware and software obey your every whim. Example topics from the past include “Building an embedded Linux system monitoring device” and “Your Shell History In The Cloud.”

Sessions for this track

* Open Source Rockets

PSAS is a student aerospace engineering project at Portland State University. We're building ultra-low-cost, open hardware and open source rockets that feature perhaps the most sophisticated amateur rocket avionics systems out there today.
Nathan Bergey, Andrew Greenberg

* Building A Mesh Network Wireless Temperature Sensor

The problem: My HVAC system is not balanced. Easy but boring solution: Hire a qualified contractor to fix it. More interesting solution: Use knowledge from dusty undergrad degree in electronics to cobble together some simple wireless temperature sensors using XBee modules and distribute them around the house. Then use Java programming knowledge to build up a monitoring system using open source software. Attempt to use readings from temperature sensors to figure out what's going on and fix it. This presentation will delve into the hardware and software aspects of the system, although with more emphasis on the software and the role that packages such as Apache Felix and Apache Mina play in the system.

* Copyright lawyers can Gödel

"This compression algorithm is of course very inefficient, at least when applied to a small collection of documents. But if you were to apply it to a larger collection, say, all the music ever recorded and all movies ever made, some gains may be realized...

* Fixing SSL security: Supplementing the certificate authority model

The most common way of using SSL/TLS encryption relies on a public-key infrastructure that puts near-absolute trust in a large number of entities around the world, any one of which could accidentally or deliberately empower anyone to impersonate any site or service and spy on all of our communications. We've seen that these certificate authorities can make mistakes. We need new mechanisms to meaningfully double-check that they're doing the right thing.
Seth Schoen

* Housetruck: Building a Victorian RV

As a "software person," I found the hard technologies of building with steel and wood made for a very different creative and hacking process. At the same time, I discovered many parallels to software development, embedded hardware, and even open-source philosophies.

* import rdma: Zero-copy networking with RDMA and Python

Every time your server sends or receives a packet, it copies it to (or from) a temporary kernel buffer. What an incredible waste of CPU and memory bandwidth! RDMA solves this, at a huge complexity cost. This talk will cover what happens when a dynamic language meets a direct-memory-placement protocol.

* Non-visual location-based augmented reality using GPS data

Augmented Reality and Geolocation have been hot topics this year, but there has often been a confusion between aesthetics vs. practicality, and fantasy vs. reality. This presentation will highlight the advantages and disadvantages of visual and non-visual augmented reality. We'll tell stories from our experiences building location-aware social networks with custom proximity notification.

Serialist (http://serialist.net/) provides a way to find, track and read serialized content (e.g., web comics). It's implemented entirely in Haskell and demonstrates functional web application development, crawling, scraping and distributed architecture. Serialist uses interesting graph algorithms to add and step through content lazily.

* The $2 computer: ultraconstrained devices do your bidding

"Do you watch television? Is your furnace loud? Do you have $2?" My 7-year-old's marketing suggestions aside, building custom gadgets to improve your life is remarkably simple, and I'll prove it by building something on stage that you can duplicate at home.
David Hollingsworth

* The Fine Line Between Creepy and Fun

Social software is kind of a big deal right now. In the open-source spirit of transparency and dissection, let's talk about what makes social technology creepy, what makes it fun, and how to hack things to maximize your desired outcome.

* X Marks the Spot: Applying OpenStreetMap to the High Seas

The United States has a treasure trove of nautical charts in digital form, including plots of shipwrecks, navigation buoys, coastal and river depths, and other fine booty. OpenStreetMap is an open source, open format collaborative project for building a free map of the world. Join this session to find out more of the marine secrets of the National Oceanographic and Atmospheric Administration (NOAA), OpenSeaMap's plans to extend OSM to the high seas, and splicing the two (and your mainbrace) together. We'll use the Geospatial Data Abstraction Library (GDAL), OGR, Python, and the OSM API.
