der.hans: Regular Expressions-A guided tour Description:
Example driven introduction to regular expressions. The talk uses plain English to explain regular expression concepts, syntax and language. Common tools such as grep, sed and awk will provide conduits for demonstrating regular expressions.
Many of our favorite system administration tools use regular expressions for text matching. While using plain English to describe regular expressions the example driven introduction will explain regular expression concepts, syntax and language. Examples will include common tools such as grep, sed and awk. About der.hans:

It's December and time for our annual end of year pot luck.
Bring friends and family.
It's a pot luck, so bring some food or drinks to share if you can. It's a holiday party, meaning we'll likely have tons of snacks and deserts. This presents an opportunity to bring a main course, salad or veggie side dish. Or, cupcakes or pie if you prefer :).
We still meet at Desert Breeze.
Since we're eating for the party, we will not go out to a restaurant afterwards.
As always, we're on the 2nd Thursday of the month.

We have 2 presentations this month:
Ed Nicholson will bring us "onBoarding for 4 free resources: Archive.org, MusicBrainz, OpenStreetMap and Wikipedia" and Stephen Partington will tell us about his adventures with LVM cache with "LVM Cache Round 2, now with some real use"
Ed Nicholson: onBoarding for 4 free resources: Archive.org, MusicBrainz, OpenStreetMap and WikipediaDescription:
This presentation is 4 mini-presentations, each about you getting set up to contribute to free public digital assets.
onBoarding Archive.org - Get your library card to over 306 Billion web pages and have a place to host your own digital artifacts. And then, there is the WayBackMachine.
onBoarding MusicBrainz - Join the Open Misic Encyclopedia, the free and open source for music information and identification. Add your knowledge to MusicBrainz and have MusicBrainz annotate, update, and correct your music collection's meta data.
onBoarding OpenStreetMap - A map of the world, and you can make it a map of your world. join OSM and start mapping your roads, trails, cafés, railway stations, etc... developer? want to use OSM data? visit Mapbox.com for access and tools and community.
onBoarding Wikipedia - the free encyclopedia that anyone can edit, if you sign up for a log-in! Have something you want to follow? Doing research? Company or Organization data sheet? Sign up and get it into Wikipedia.About Ed:
I have been involved with Free Software and how people, organizations and populations use, create and experience information. I enjoy The Prescott National Forest as my "office" and The Valley of The Sun as a home away from home. Personal systems run either Fedora, Project Atomic, Android or OpenBSD.
Stephen Partington: LVM Cache Round 2, now with some real use.
Having Presented the LVMcache in using an SSD to speed up your system, single disk, or array some time ago, this will be a follow up with the real time experience and use of LVMcache and its application in day to day use.
20+ years of Technology, Almost as many of that with at least some level of supporting or using Linux desktops and servers. Into gaming, Technology, Mobile devices, Linux, Photography and Maybe soon Blacksmithing.
We'll have 2 presentations at our Thursday meeting. Joseph Sinclair will present Modern C++ on Linux
and Ed Nicholson will present Project Atomic and Immutable LinuxJoseph Sinclair: Modern C++ on Linux
C++ today is very different from what it was just a few years ago. The revitalized and fast-moving (for ISO) standards process as well as major changes both to the language core and the standard library have produced almost a new language.
This presentation is a practitioner's perspective on the state of C++ development on Linux platforms today, the recent standards improvements, how "good" C++ idiom today looks almost nothing like "good" C++ from 15 year ago, and perhaps a bit about all the ways C++ code is done badly.
No slides, but some live code samples are possible.
Joseph Sinclair is a software engineer, long-time linux user, and general all-around tech head. He occasionally wonders what it would be like to dream in binary, and sometimes remembers that most people don't actually know what a convolution code is or why 8b10b encoding is important.
Ed Nicholson: Project Atomic and Immutable Linux
This presentation is about the changes to a system's life cycle as an Immutable Linux such as Fedora-Atomic.
Immutability of a system has been an objective for some time, and with good reason. The shift in deployments to containers has made this a critical feature for the stability and manageability of the large number of systems that support the services we have today. We will look at how this has resulted in some very basic changes to a typical systems life cycle and how easy it is for you to have your own container ready servers.

We'll have 2 presentation on Thursday, "Intermediate shell scripting: getting more bash for your $" and "SSH and the shell-go forth securely", both from der.hans
der.hans: Intermediate shell scripting: getting more bash for your $
Want to take your shell scripting to the next level? Interested in adding string manipulation and arrays to your arsenal? In shell math?
Shell still has the best system integration for stringing together our favorite command line tools such as ls, grep and sed. Better yet is doing some of that work in the shell without reaching for a forked program, especially inside loops. This presentation will cover intermediate scripting techniques and useful command line tips.
After attending this session, audience members will understand string operators, in shell math, indexed arrays and associative arrays. They will also be familiar with regular expressions, globbing and differences between the two. Finally, attendees will be familiar with useful builtin variables.
der.hans: SSH and the shell-go forth securely
SSH is the go to tool for sysadmins and developers for interactive connections to remote machines. It creates secure, encrypted connections between computers, even across hostile networks. Unless you accept keys without verification (DON'T DO THAT!!!).
SSH can also create tunnels for encapsulating other connections, including other protocols and data. Sysadmins can bridge protocols across networks for ease of access such as a one-off data sync. Devs can present the dev database on their desktop to ease use of graphical development tools.
After attending this session, audience members will be able to create a local tunnel from client to server, a remote tunnel from server to client, and do simple analysis of local vs remote evaluation of a command. Attendees will be able to use tunnels for SSH or sample other protocols (MySQL and HTTP), and tunneling via a third party system. They will also be familiar with dynamic SOCKS proxies and using SSH to tunnel graphical applications. Finally, attendees will also learn SSH configuration and command line tips for convenience of use, including using forced command to restrict an SSH key to one purpose.
der.hans is a technology and entrepreneurial veteran. Roles have included director of engineering, engineering manager, IS manager, system administrator, community college instructor, developer and DBA.
