26 years of teaching Unix/Linux

Abstract:

The Unix Operating System has been around since the 1960s and has provided the backbone for the modern "Internet."

The core of the Unix and Linux experience is the command line shell. This powerful text based interface can be leveraged to automate tasks and solve problems that would be too tedious to tackle. The Born Again Shell is available on all Unix and Linux platforms. A clear understanding of the features of the shell along with a basic set of commands can improve your productivity and change the way you implement solutions to text based problems.

Eric will provide an overview of how his Unix/Linux classroom has evolved over 26 years. From the blackboard handwritten lecture in a room without computers to modern classroom with a computer on every desk. Through it all, the common set of command line capabilities has remained a staple in the Unix/Linux mindset. sed, grep, cut, tr, and awk are tools that can be combined to transform the simplest of users into a "Power User".

Bio:

Eric Danielson was first exposed to FORTRAN as part of a Saturday high school program at JPL. Before that, he hadn't been exposed to computers except for watching his father open up a briefcase sized modem to transfer files using the house phone handset. The Saturday class would walk onto the JPL campus and sit at someone's desk to log into a VAX terminal to edit, compile and run FORTRAN77 code.

Eric has since earned a B.S. in General Engineering from Harvey Mudd College and a M.S. in Computer Science from USC. Eric started working at JPL as a summer student. At that time, he was running radiative transfer code (FORTRAN) and supporting a science team. After the brand new Sun Microsystem workstations were installed in the Science Division computer lab, Eric took some evening classes at Glendale College that included C Programing and Unix Shell Programming. Soon after, a co-worker and mentor at JPL encouraged Eric to take over his teaching workload at Glendale College. An increase in his JPL travel schedule was making it difficult to continue teaching. Eric started teaching BASIC Programming and FORTRAN in 1989. He eventually took over the Unix class and has since added the Unix/Linux System Administration class to the Glendale College curriculum.

Eric is currently the Science Data System (SDS) System Engineer for the Multi- angle Imaging SpectroRadiometer (MISR) instrument on the Terra Earth Observing System satellite and the Multi-Angle Imager for Aerosols (MAIA) instrument currently in development.

Eric enjoys tinkering with Raspberry Pis and Arduinos in the creative realm of "Makers". His recent projects include a portable air quality monitor and a time-lapse camera with a Raspberry Pi.

Summer App Space

The wonderful folks at OpenX are hosting this meeting, and they are also providing pizza. We need to provide a list of names to building security. RSVPs will be capped at 80. Contact Lan if you have questions.

Topic

In this talk Dr. Corbett Moran will discuss the challenges and rewards of instructing a mixed skill class in an apprenticeship style learning environment.

On June 26-August 4, 2017 she led a summer program, Summer App Space, for LA students and teachers to learn programming while getting paid to do fun space-related projects. Her work on this was supported by NSF Astronomy and Astrophysics Postdoctoral Fellowship award AST-1501208. Summer App Space is a paid apprenticeship where high school students are paid to attend a six week school learning to program in Python and the fundamentals of Linux, 20 hours per week. Four weeks are lecture and lab based, and the last two weeks are project based incorporating a deliverable product and entrepreneurial style teams.

Bio

Dr. Corbett Moran is the lead curriculum designer, recruiter and instructor for the Summer App Space (SAS) 2017 program. She brings to the table extensive experience in running such programs from a teaching, technology, organizational, scientific and industry connection perspective.

She taught introductory and advanced courses in MIT MEET: Middle East Education Through Technology for two summers. MEET is a gifted high school program in which she taught Java programming and mobile app development in a project, lecture, and guest speaker format. MEET's mission is creating a common professional language between Israeli and Palestinian young leaders. Dr. Corbett Moran served as the lead technical instructor in MIT's Global Startup labs in the Philippines for a summer to students from a variety of backgrounds and socio-economic status in the Manila area in a highly similar format to that planned for SAS. She has organized speakers and technology for TEDxZurich as well as hackathons for Open WhisperSystems and a site of the NASA Space Apps Challenge, on which she is basing SAS projects.

Dr. Corbett Moran dually majored in Physics and Computer Science at MIT, obtained a Master's and Ph.D. focusing on Computational Astrophysics at UZH, and her NSF Astronomy and Astrophysics Postdoctoral Fellowship research is at the intersection of the two. She has worked for SpaceX as an intern in Propulsion Analysis and has over 10 years of industry programming experience in cutting-edge web and mobile technologies. Dr. Corbett Moran has served as a teaching assistant and lab assistant for 8 courses, spoken around the globe as a highly praised public speaker, and mentored several students. Dr. Corbett Moran's participation has been enabled by NSF Astronomy and Astrophysics Postdoctoral Fellowship award AST-1501208.

Rustlang for your brain. Rustlang for your team. Rust, for Justice.

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

ABSTRACT:

Rust is a new and exciting systems programming language promising strong typing, cost free abstractions, and fearless concurrency. Some of these hard problems have plagued all programming languages for years. We'll talk about why Rust helps you think about other programming languages more accurately, why Rust helps you communicate with your team, and how you can help test some actual Rust code every day to help the Mozilla foundation improve Firefox.

SPEAKER:

Clint Byrum - Senior Cloud Engineer, GoDaddy

Clint has spent decades in the tech industry, using, developing, and maintaining Free and Open Source software. He is an active member of the Ubuntu, MySQL, Gearman, Debian and OpenStack communities. If it's not in version control, Clint does not know it exists. When not evangelizing continuous delivery, writing tests, automating deployments, and developing code in Python, C, Rust, Ansible, and/or Bash, he spends time raising his 4 children, playing Roller Hockey and doing CrossFit in Los Angeles.

The Young Man and the C Reloaded

The Young Man and the C Reloaded

What if I told you that most or all nontrivial C and C++ programs you have ever written were just illusions? Most such programs contain undefined behavior, and undefined behavior is at the heart of most C and C++ security problems, yet few programmers understand how far down that rabbit hole goes. We will swallow the red pill and study the nature and extent of undefined behavior in C and C++, techniques for writing more secure, reliable C and C++ in spite of the reality of undefined behavior and other mischief, and little-used compiler flags and other tools to detect and/or eliminate bugs.

Dustin Laurence Bio

Intending to become a programmer ("developer" hadn't been invented by the marketing department yet), Dustin got sidetracked and spent more time than he cares to admit doing theoretical physics, a background filled with continuous mathematics almost entirely irrelevant to computer science. He eventually returned to his original love of programming, and though they probably won't admit it currently hacks code for Whitemoon Dreams, Inc. He avoids social media for the same reason he doesn't do crack cocaine.

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.
