Custom Computer Projects

Abstract:

One of the many strengths of Linux is that it runs on commodity hardware from an extensive PC ecosystem. We have the freedom to assemble components in a way that is customized for our own specific needs. And now we can easily continue our customization to the physical form factor, thanks to recent advances lowering the cost of fabrication technologies like 3D printing and laser cutting. Not just the cosmetic art of the "case mod" audience, either: motivated tinkerers can build functionally useful creations and share them with the world.

We will walk through several custom computer projects, starting with the "Luggable PC" seen at recent SGVLUG meetups. Each project has its own motivation, design constraints, and undergo several iterations to refine the idea. The latest version of each project will be available for hands-on examination, some accompanied by their predecessors to show design evolution.

Raspberry Pi, VOIP, and Amateur Radio

Abstract:

The Raspberry Pi has become a favorite of Amateur Radio operators world-wide. Although most of the development on projects is occurring outside of the United States, there are a significant number of products and hacks available. Repeater controllers, VOIP servers, and even turning your Pi into a transceiver is possible and is being done.

NASA World Wind

This month, we are hosted by Everbridge at their training center. Everbridge is also sponsoring food and drink.

TOPIC:

NASA World Wind is an open source virtual globe that makes it easy to build 3D geospatial applications. World Wind provides APIs for Java, Android, and JavaScript, and includes a powerful set of capabilities for visualizing and interacting with spatial data and imagery. In the first part of this presentation I will discuss some the main features of World Wind, as well as the World Wind team's development philosophy. The second part of the evening will be an interactive workshop, in which we will build a simple geo application using the Web World Wind JavaScript API.

BIO:

Parker Abercrombie is a senior software engineer at NASA's Jet Propulsion Laboratory, and is the project lead for OnSight, a mixed reality tool that allows scientists and engineers to work virtually on Mars. Parker is also the lead developer of the science targeting software for the upcoming Mars 2020 rover mission. Prior to joining JPL, Parker worked on geovisualization software for NASA's Ames Research Center and the U.S. Department of Energy, including World Wind, winner of the NASA Software of the Year Award in 2009. Parker holds an M.A. in Geography from Boston University, and a B.S. in Creative Studies from the University of California, Santa Barbara (which he swears is more technical than it sounds).

Lawyers vs Developers, The Fight Over FOSS in Enterprise

Topic

Enterprises have learned that Open Source is the way to develop great and mature software. Leveraging open source tools and packages allows the enterprise to go to market faster and have stronger applications. Therefore, using Open Source tools is a no brainer for developers. The lawyers on the other hand don’t see it the same way.

The speaker had the privilege of working with the Open Source approval and review process in a large security firm. In this talk, he will share lessons learned from this process and some best practices that developers should do to make the Enterprise Lawyers happy as much as the developers are.

Each organization that uses Open Source software – even in an unedited form – has a list of FOSS licenses that are acceptable and some that are not. Also, has strict requirements on how to handle the software and how to incorporate it in the distribution of the company’s products. In this talk, we go through some of the lessons learned and pitfalls that some Open Source packages have, such as:

  • Not inserting a copyright clause in project code or homepage

  • Asking the user to alter the code in order to change the license from GPL to MIT, for example

  • Using dependencies that could be outdated or have CVE’s against it

  • Not providing enough information to build the code from scratch

Intro to Internet Security with Pi-Hole and OpenVPN

This month, we are hosted by Everbridge at their training center. Everbridge is also sponsoring food and drink.

Topic

Protecting your digital identity, passwords, and browsing activity is difficult in the world of open Wifi networks, freeware, and advanced advertising techniques based on tracking users across the web. While complete privacy is not possible while connected to the internet, there are many things you can do to make access to your personal data more difficult. This presentation will focus on the basics of internet security, how to begin protecting your network and your data, and why it's so important. We will focus on the two most prominent (and easiest to fix) security vulnerabilities: encrypting your browsing on external networks using OpenVPN, and blocking advertising and tracking as early as possible using Pi-Hole.
