DCRUG: CarrierWave+S3 + What Computer Scientists Know: Recursion

  • Oct 10, 2013 · 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:

  • "CarrierWave+S3: Cheap & (now) easy automated file upload & storage" by Lisa Schaefer

    Heroku provides free rails hosting while you're developing your app. However you cannot have users upload and store files on the free version. There are several inexpensive services for file storage and a few gems to facilitate file transfers.
    Lisa Schaefer will discuss how to use the CarrierWave gem to upload and store files on Amazon S3. She will tell us about the information resources you'll need for getting your app to work with CarrierWave, along with some of the glitches you might encounter on the way.

  • "What Computer Scientists Know: Recursion" by Dave Bock

    So you came to software development from some other background, and wonder wht you missed not getting a "traditional computer science degree"?

    I might not be able to give you a com sci degree in a couple of short talks, but I can hit the highlights.  In this first of a series of talks, you'll learn about recursion… the act of solving a problem by defining a method that calls itself, getting closer to the solution each time.

    Bring your thinking caps, because we'll start with a 10 minute thought experiment based on one of the Project Euler problems (

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.

    Sorry I missed. I'm down and out with some sort of flu/bronchitis illness. Wasn't up to leaving the house. Any chance I can look at slides and such?

    Super presentations! I'm still pondering the empty string object-originated big bang.
    The recursion was terribly interesting for this non-comp sci guy, but giving me just a slight a good way. :)

    Was Robert Dempsey not able to make it tonight? Was looking forward to his talk.

      I saw a version of it before at data science DC lightning talks, but was hoping to see it with a bit more breathing room as far as time.Unfortunately Tigers in game 5 are going to prevent me from being there tonight.

      Robert, I'm sure I'll see you at another meetup and can talk to you about it then.

      Hey Dave, you've definitely provided edutainment at past meetups I've been to, so I have no doubt tonight will be any different :)

      Have fun tonight everyone!

    Robert had to cancel/postpone for some reason. I gave this recursion talk last night at the Arlington group and was asked to fill in at the last minute. I hope Robert makes it back, and I hope I provide you some good edutainment in the interim.
