Using Open-Source Tools for HW/SW Development at JPL

Please note that the previously advertised presentation "BIG DATA! 24 hour near real time processing and computation for the JPL Airborne Snow Observatory" is being rescheduled for another time. Big thanks to Dmitriy and Tom for being willing to put together a presentation for us on short notice. Cookies have been promised.

Tom and Dmitriy will present on how they use open source tools at JPL in their line of work. These tools include: Raspi, GStreamer, Mercurial/Trac, Wireshark, vi, and others.

BIO: Dmitriy Bekker and Thomas Werne are currently staff engineers in the Instrument Flight and GSE Software group in the Instrument Electronics and Sensors Section at JPL. They are working on FPGA-based data acquisition and processing designs for multiple prototype science instruments for ground, space, and airborne applications as well as technology development for small satellites. Their projects have been deployed to the Mojave Desert, on high altitude aircraft, at observatories, and on CubeSats.

Introduction to Security using Raspberry Pis

We will demonstrate 4 basic security topics, all using the Rasberry Pi computer.

Topcs include:

  • "Change Default Passwords, or Else.....if"
  • "Clear Text Passwords and HTTP Make Jack a Sad Boy"
  • "Cookie Stealing with Joe Blackhat"
  • "Stack Smashing in the Real World".

Come to learn a taste of security, or simply enjoy the show.

(You can also come for the cookies and/or pie, which was what the presenters demanded as a bribe.)

Distributed Version Control & Mercurial

Lan will talk about distributed version control systems (DVCS) with a focus on Mercurial. The talk will be suitable for both beginners and advanced users.

She will go over the basic concept behind DVCS, such as directed acyclic graphs. She will highlight some of the differences between Mercurial and git, the other popular DVCS. For the beginners, she will go over some basic Mercurial commands. For the advanced users, she will share some interesting case studies from work.

Redmine

Christefano Reyes presents on Redmine, a free and open source project management and issue tracking system written in Ruby on Rails. Prior to this presentation, attendees are welcome and encouraged to download it, use a shared demo or try a private, one-click install.

Popular with (but certainly not limited to) the Ruby on Rails developer community, Redmine is a full-featured system used by companies, open source projects, governmental agencies, and individual developers around the world. Big users of Redmine include open source projects such as Ruby, Puppet, Gentoo, Lighttpd, TYPO3, and the Redmine project itself.

This presentation will focus on how Redmine is used from the perspectives of developers, tech leads and project managers at a software development company. Features that will be demonstrated include:

  • User and group management;
  • Feeds, email notifications and web-to-mail and mail-to-web support;
  • Per-project role-based permissions,
  • Time tracking and reports; including calendaring and Gantt charts;
  • Issue workflow management across multiple roles;
  • Redmine's plug-in architecture and growing developer ecosystem;
  • Custom fields for extending user accounts, time entries, and other data structures;
  • Redmine's REST API and how it integrates with third-party platforms.

Christefano is one of the founders of Exaltation of Larks, a Drupal strategy, development and training company; and Droplabs, a coworking space and classroom near Downtown Los Angeles. As an advocate of open source software, he helps organize meetups and conferences all over the Greater Los Angeles Area. In his spare time, he trains as an amateur acrobat and gymnast at the Original Muscle Beach in Santa Monica.
