PLUG's Upcoming Events
We have two presentations for August: Software Defined Radios; Intro to Amazon Web Services.
Topic: Software Defined Radios
Speaker: Schuyler St. Leger
Description: Software Defined Radio (SDR) provides the perfect low-cost method to explore the world of RF (Radio Frequency.) SDR is a flexible radio system that utilizes software instead of specialized hardware to decode radio signals. It can investigate a wide frequency range and decode many different RF protocols. This talk will provide a basic understanding of SDR. It will then discuss some of the available and affordable hardware and software tools for exploring SDR. If time allows a live SDR demo will be included.
Bio: Schuyler St. Leger is a young maker. His passion for technology started at a very early age. His interests include 3D printing, electronics, hardware and software programming, software defined radio (SDR), robotics, computers, and tech innovations. Schuyler regularly speaks and teaches on these subjects. He dabbles in many software and hardware technologies including 3D CAD tools (Autodesk Inventor and 123D, SketchUp, and SolidWorks), LabVIEW, MATLAB, Python, Processing, Scratch, Linux, Arduino, and LEGO Mindstorms. He enjoys designing and making things as well as taking apart nearly everything to understand the details of how they work. He shows his projects at various maker events worldwide. Schuyler is a member a FIRST Robotics Competition team, Team Caution Robotics, and also a member of HeatSync Labs, Phoenix’s hackerspace.
His motto is “Don’t be afraid to break something!”
Schuyler lives in Phoenix, Arizona and is currently in high school at Brightmont Academy.
Topic: Amazon Wed Services (AWS)
Speaker: Tejeev "TJ" Patel
Description: An Introduction to Amazon Web Services (AWS)
This month we will have 3 presentations.
Aaron Jones will give a presentation on VIM
The bare bones bottom of the barrel basics of VIM. People who reset their computer because
they accidently opened VIM and don’t know how to get out of it will enjoy this. We will discuss
the three modes, how to insert, edit, and save data. I will also demonstrate what a .vimrc file can
be used for when customizing VIM.
I am a VIM user who currently uses VIM for all aspects of both my job as well as my personal
life. I really love VIM and it currently doubles as my coding environment as well as my Word
Phil Waclawski will give us 2 presentations:
The basics of Subsurface (He'll even demonstrate unloading his dives from his dive computer), some of the more advanced features as well.
Color correction and other basic photo editing using Gimp, focusing on SCUBA photos that have a bad blue "washout" effect.
We have 2 topics this month:
Topic: An IRC bot written in Elixir
Description: A walkthrough (and maybe demo) of a simple but non-trivial IRC bot written in Elixir (a new, fun, functional language that runs on the Erlang VM).
Bio: Darrin has been developing software since the 80's, currently for Limelight Networks, and previously in areas ranging from a NASA space mission to finance to 3D modelling. Darrin has been developing for Linux and/or BSD since the 90's, and exclusively since 2008.
Topic: Hugin: Panoramic Image Stitcher
Speaker: Brian Cluff
Descrition: Hugin is a powerful program to combining images into panoramas. It is easy to use, but needs quality input to work correctly. This presentation will give an into to using Hugin as well as advice on how to take high quality input images so that your panoramas will always turn out perfect. There are also many other things that can be done with Hugin and a few notables items will be shown.
See you there...
We have two talks scheduled for May, "MySQL for system administrators" and "Mesh networks and the Internet of Things"Topic
: MySQL for system administratorsSpeaker
: MySQL is ubiquitous. It will be for many years. A little knowledge will go a long way to having a good MySQL setup. A little knowledge will also leverage your command line knowledge when working with MySQL.
Restorals are paramount, but you can't just backup the files. Databases
have special requirements for proper backups. MySQL has mechanisms for controlling access, but general system administration tools can be used in addition to the MySQL grants.
MySQL has several database engines available, choose wisely and configure it properly before starting.
The slow query log can be useful for finding long-running queries, but
it's not the only place to find useful log information.
The presentation will also cover OS changes and good practices that will
help the system administrator use and administer MySQL without having to
become a DBA.Topic
: Mesh networks and the Internet of ThingsSpeaker
: An roundup of common mesh networks and an introduction to the Internet of Things
First Topic (Held over from last month due to laryngitis):
Brian Cluff - Hidden features of the Kdenlive video editor
Brian will cover a number of very useful features he has found while editing the videos he shots of the Phoenix Linux Users Group.Second Topic:Discussion about SCaLE 13x by those who attended
