Hacking on the new Beagle Bone Black

Description:

Russell recently spent some time working on porting a house-monitoring system from the Beagle Bone (an $89 embedded, ARM-based, I/O rich device running linux http://beagleboard.org/) to the new Beagle Bone Black, a $45 device which is faster, includes video and 2G of onboard flash. The sensors required a one-wire bus, one of which the original Beagle Bone had configured out of the box. The Beagle Bone Black had none. This talk is a description of what it took to get one-wire (specifically w1-gpio) going with his own custom "cape" (a daughter-board for the Beagle Bone).

Biography:

Russell Senior has been a GNU/Linux user for over 20 years, since the 0.99plN days, using it both recreationally and professionally as a research programmer/scientific data analyst. Since 2005, Russell has become involved as a principal volunteer with the Personal Telco Project (https://personaltelco.net), during which he has worked on embedded systems, primarily network routers. He contributes to the development and improvement of the OpenWrt project. In the last couple years, he has worked on monitoring systems involving Arduino and, since last year, the Beagle Bone and has learned a bit about the Angstrom distribution of linux for embedded devices.

Mozilla Socorro: an Open Source crash reporting system evolves.

Socorro collects and analyzes three million crash reports a day employing PostgreSQL, HBase, Hadoop, and ElasticSearch glued together with Python. Socorro's data analysis drives the stability and development priorities of Firefox. Five years ago, Socorro was a system that ran on three machines and was tended by just one person. In 2013, it has evolved to become a distributed system running on 120 machines and serving hundreds of terabytes of data. Meanwhile, companies all over the world are adopting Socorro for crash reporting. This talk, an update of one given several years ago, will track the evolution of Socorro and its future in the upcoming world of FirefoxOS.

K Lars Lohn is the Herd Patriarch of the Mozilla WebTools Group. As the author and curator of the Mozilla Socorro Crash Reporting System, Lars has driven its evolution. Formerly with the OSUOSL, Lars telecommutes for Mozilla from a farm near Corvallis. While preferring Python, PostgreSQL and Harleys, Lars is versed in C++, MySQL and Subarus.

Historically, implementation of electronic health records in medical offices have been problematic. Specifically, poor implementation of these products is the leading cause of failure of acceptance of EHRs in these offices. Implementation of EHRs in the small physician office remains poorly documented and this contributes to this failure rate. To address this need, OEMR (The OpenEMR Non-Profit) developed an internship experience with the Department of Medical Informatics and Clinical Epidemiology at Oregon Health and Science University to develop a road map for converting a small physician's office that is still using paper records to OpenEMR, an open source electronic health record, while using open source tools to implement and document the transformation. Documentation was made public on the OEMR wiki (at http://www.oemr.org/wiki/Going_From_Paper_to_Electronic) as a template for future implementations. This presentation is an overview of the documentation completed for the wiki. There are many paths to implementation, but the destination is meaningful use of the OpenEMR system.

Special Thanks: PLUG regular Keith Lofstrom was instrumental to the success of this project, not to mention Dr. Sam Bowen, MD in North Carolina and PLUG speaker Tony McCormick.

Diane Petersen is an emerging clinical informaticist, drawing from her formal education in clinical informatics and her extensive experience as a clinical pharmacist in a variety of settings. Having completed an internship leading and documenting the implementation of OpenEMR, an open source ambulatory electronic health record and practice management software application, Diane is in her last term of the Masters of Biomedical Informatics program at Oregon Health and Science University. She plans to apply her background and knowledge contributing to the improvement of managing healthcare data, and ultimately the improvement of patient care and outcomes.

ChickTech is proud to showcase the results of our first annual ChickTech: High School event! Our 100 high school participants will have worked hard all weekend to create an awesome project in one of our seven workshops. Stop by and see what they've created! Most won't be a finished project; they have another 10 hours in our shorter followup events throughout 2013 to finish, but we think you'll be amazed by their creativity and progress, especially since most of our participants have never been exposed to programming or hardware before.

Cheer them on and encourage them to keep making progress! We look forward to seeing you there.

Learn more about ChickTech: High School on our website: www.chicktech.org.

Eric Harrison has over 15 years experience with Linux in primary and secondary education environments (Kindergarten through High School). Topics will include designing, building, and maintaining your own Linux distributions (K12LTSP & Edubuntu), infrastructure (clustering, virtualization, web filtering, etc), large scale Asterisk telephony deployments, IPv6, and more.

UEFI Secure Boot and Open Source. It's not a 'general war against computation' by Vincent Zimmer, Intel

As 2012 platform firmware embraces UEFI 2.3.1 and ACPI5.0 support, the ability to interoperate with UEFI Secure Boot is imperative. This poses a unique challenge for open software that may not come pre-installed on the platform. With UEFI Secure Boot, though, infrastructure has been put in place to preserve openness, owner choice and control in addition to mitigating concerns of malware targeting the platform. This talk will provide a history of UEFI Secure Boot, an overview of the implementation, deployment practices, and details on the engagement with the open source community.

Vincent Zimmer is a Principal Engineer with Intel Corporation. He has been working on various platform, networking, trusted computing and security technologies around EFI since 1999 and platform firmware since 1992. Vincent has spoken in various forums on this topic, co-authored 3 books, 10 papers, and several specifications in this area.

Portland Linux/Unix Group Meeting

It's a little known secret that systemd is extremely capable of starting, controlling and regulating more than just system services, but can easily start an entire Desktop UI. Not many people have sat down and implemented and worked out the problems of starting an X service, a few UI components, the session bus and DBus services for normal users with the mechanisms that systemd provides.

The benefits are obvious: Systemd provides excellent service monitoring and restarting capabilities, provides socket and DBus activation for relevant services, and overall improves desktop startup by allowing user services to start well before core services like Xorg or wayland start. In effect, we're saying goodbye to XDG autostart entirely, and getting back reliability and scalability.

We converted several desktop environments including Tizen's Mobile UI, Xfce4, Enlightenment and more to systemd user sessions. We "pop the hood" and take a look at the implications for startup, what's possible to further improve on the session startup and where we can do better.

Auke Kok is a software engineer at Intel's Open Source Technology Center, and has been attempting to make Linux boot faster since 2007. In 2008, he co-presented the "5-second boot" with Arjan van de Ven at the first LPC. Since then, Auke has worked on further improving the Linux Core OS start sequence, first for Moblin and later with MeeGo, where we made the first switch to systemd. Auke now works on Tizen, which will heavily integrate systemd in the Core OS.

Lance Albertson of the Oregon State University Open Source Lab will give an introduction to the Ganeti Virtualization Management System.

Ganeti is a robust cluster virtualization management software tool. It’s built on top of existing virtualization technologies such as Xen and KVM and other Open Source software. Its integration with various technologies such as DRBD and LVM results in a cheaper High Availability infrastructure and linear scaling.

This hands-on tutorial will cover a basic overview of Ganeti, the step-by-step install & setup of a single-node and multi-node Ganeti cluster, operating the cluster, and some best practices of Ganeti. Finally, deploying and using a web-based management tool called Ganeti Web Manager.

If you want to participate on the hands-on portion of the talk, feel free to clone his vagrant-ganeti repo on github (https://github.com/ramereth/vagrant-ganeti) prior to the meeting. We'll try and have the box images available on USB drives at the meeting but its always great to have everything setup prior to the meeting and not saturate the wifi.

Lance is the Associate Director of Operations for the Oregon State University Open Source Lab (OSL) and a Gentoo Linux Developer. He joined the Gentoo Linux project in 2003 and have been involved in managing their infrastructure and maintaining about a dozen or so packages in portage. Lance directs all of the hosting and development activities that the OSL provides for the open source community including projects such as Kernel.org, Drupal, Apache Software Foundation, and many many more. Lance has been at the OSL since 2007.
