1. My NSLU2 (slug + urchin = slurchin?) Open Source Software Carlos Ramirez Martinez-Eiroa Professor: Corby Schmitz

2. Index Brief Description Why I chose it Learning objectives Project objectives Functionality Tools License Tools to manage the project Packaging and distribution

3. What’s an NSLU2? Network Storage Link for USB 2.0 Disk Drives Connects USB 1.1 or 2.0 disk drives and flash disks directly to your network

4. SlugOS/BE SlugOS/BE: Open source firmware for the Linksys NSLU2. Based on the Linksys firmware. The Slug (NLSU2) runs Linux => Linksys released the source code. SlugOS/BE takes the Linksys firmware and expands upon it.

5. Why I chose it Big share of the software developed market is for embedded systems Less common than web or desktop app development More hardware in the market at “reasonable” prices that can be hacked

6. Learning objectives Operating Systems: Linux Build Tools: BuiltBake Languages: C/C++, Python Web services NAT (Network Address Translation) => for the router the Slug connects to

7. Project objectives Integrate great lightweight open source software with high quality cheap hardware Create a basic home security system that can be accessed through the Internet

8. Why with a Slug? A lot cheaper than using a full laptop or desktop Open-source scripting languages such as Python are supported

9. Hardware 1 slug 1 flash memory (better an external hard drive) 1 or more webcams (other sensors in the future) Ethernet cable Typical modem + router home network

10. Functionality The camera starts recording when it detects movement It saves the video for an X period of time, before overwriting it The recordings can be accessed through the Internet Exposes the monitoring functionality in a RESTful style

11. Extended functionality Other sensors, such as: –Temperature –Smoke alarm

12. Tools Eclipse –CDT plugin for C/C++ –Pydev plugin for Python OpenEmbedded: “set of metadata used to cross- compile, package and install software packages” –BitBake: “controls how to build things and the build dependencies”

13. License GNU General Public License (GPL)

14. Tools to manage the project Provided by either SourceForge.net or GoogleCode: –Wiki –SVN Repository –Bug Tracker

15. Packaging and distribution Source Tar Zip
