Ponder for a moment: What actually happens when you type '' in your browser and hit enter?
The answer is surprisingly complex.
How does your web browser contact that remote server? How does it download the information? How does it render it on your screen?

Here's a summary of just some of the subsystems invoked before the KyOSS web page is rendered in your browser:

TCP/IP -- the backbone protocols of the internet
DNS -- the "Directory Assistance" of the internet
Whois -- the "Supervisor" for the "Directory Assistance" of the internet
HTTP -- the lingua fracta of web pages
Cookies -- your personal ID on the web
TLS / SSL -- encrypting connections since 1994
Ethernet -- the driveways, side streets, and highways of the internet
...and more

Jeff Squyres, Deven Phillips, and Alan Blount will lead us on that labarynthian journey thru the interwebs.

Tonight, something for everyone!
For the gurus amongst us: A report from the recent QCon conference in San Francisco, including a lot about microservices, Docker, and orchestration.

And for the rest of us, it's back to the basics:
Master the command line and answer those nagging questions about just how *nix works.

For Linux basics, we'll do a "once over lightly" followed by a drilldown into those topics of interest.

Here's what's on our list so far. (Let us know what other topics you'd like us to cover.) :

• the UNIX Philosophy (build simple, general, pluggable tools that can be reused)
• navigating the command line
• command history
• piping and redirection
• grep, sed, and awk (and a bit on regular expressions)
• sort, uniq, wc
• shell scripts
• init systems (System V and Upstart)
• daemons
• top and ps aux
• start up scripts
• cron
• ssh
• screen
• find

Join us for an evening of all things open.
Max Battcher will be giving us a presentation on Mozilla Persona, the open source "single sign-on" system that gives you more privacy than comparable systems like OpenID and Facebook's similar service. Here's: Wikipedia on the subject. Persona made the news in March when Mozilla announced it was handing the project over to the open source community.
Our thanks to TEK Systems for providing the venue and refreshments!
