July DCRUG: Ruby Text Classifier & DevOps Adventure

  • Jul 10, 2014 · 7:00 PM
  • This location is shown only to members



Our meetings are open to all experience levels, from total novices to expert Rubyists.

Current agenda:

• Brian Muller will talk about a text classifier in Ruby that uses Hadoop/HBase, Mongo, or Cassandra for storage. 

• Nathen Harvey will talk about "something cool and DevOps related". It's a veritable choose-your-own-adventure of DevOps awesomeness :) Guaranteed to be fun! 

We now meet monthly at Logik's new headquaters, now located at 1400 I (Eye) Street NW, Suite 800 Washington, DC 20005. The closest Metro stop is McPherson Square. If you're downstairs and need someone to let you into the building or the elevator, please give me a call at[masked] or tweet me at @naffis.

We always need presenters, so if you have a topic or project on which you'd like to do a 30-minute presentation on anything Ruby-related, Rails-related or possibly of interest to Ruby developers, please contact our organizers [masked] and we'll schedule you to speak. If you have presented before, you are welcome to give a presentation on a new topic. This is a great chance for some of you guys and gals lingering in the back of the room to share some of the cool things you are working on. Don't be shy -- you're among fellow geeks. :)

As always, we'll have an ample supply of free pizza and soda for all attendees, so don't worry about eating dinner beforehand.

And we'll be heading to a nearby bar after the meeting, to unwind and socialize with fellow techies.

    I would love to hear about the new Chef Development Kit and how it can be used today and in the future.

    I'm also interested in how to use Chef to manage Mac laptop configurations. Since the Mac OS X operating system cannot be virtualized, do you have tips on testing Cookbooks for the Mac.

      A good start on ways to use Chef to manage Mac configurations would be SoloWizard http://www.solowizard...­ (a tool the folks at Pivotal wrote to manage their Mac OS X development machines) and "Chef Cookbooks for Mac OS X" on GitHub:­

    I'm really looking forward to this week's meetup! As the talk description says, it'll be a "veritable choose-your-own-adventure of DevOps". What that really means is that I need your help! I love DevOps and Chef and can talk all night about either. Let me know if there are specific things that you'd like to hear about so I can be sure to include them. Want to talk about the best linter for your ruby code, the role of "operations", best practices for Chef, the latest cool chef tool: chef-metal, what the best DevOps tools are, or anything else? Nothing's off limits, ask me anything! Ping me on twitter (@nathenharvey), send me an email ([masked]), or leave a comment here so I can have something about your favorite topic prepared! Oh, and here's a short video I made to explain DevOps -

      I'll make my slides available but am about to leave on a week's vacation. I still need to do a little bit of clean up on them before I can post.
