Welcome to DDL!

About Us

The Dayton Dynamic Language User Group is primarily focused on, as you can tell by the name, dynamic languages. If you’re interested in Ruby (including Rails), Python (including Django), PHP, Perl, Javascript, Scheme, Lisp, Smalltalk, etc, this is probably the place for you. We try not to talk specifically about things like C and Java, but there are no hard and fast rules (especially if you’re comparing them to a dynamic language).

The meetings are very informal. We usually don’t have any formal presentations, but people frequently show code that they’re working on. The flow of the meeting tends to meander, so if you’re interested in something specific, you should speak up!

The meetings are free to the public, though we try to donate some small amount of money to the Dayton Chess Club every month. You’re certainly under no obligation to contribute.

Special presentation

Elasticsearch is an increasingly popular way to easily provide sophisticated searching and filtering of data, especially unstructured data. More formally,

“Elasticsearch is a highly scalable open-source full-text search and analytics engine. It allows you to store, search, and analyze big volumes of data quickly and in near real time. It is generally used as the underlying engine/technology that powers applications that have complex search features and requirements.”

Seph Coster will provide an introduction to Elasticsearch with a hands-on component. Bring your laptops if available!

A Stockingful of Languages

December 14, 2016

You know those cute or quirky little gifts you cram into the kids’ stockings? That’s what we’re doing for December - an assortment of small or odd programming languages that we wouldn’t (or can’t) make a full meeting of, but put them together and they’ll make a fun grab bag.

Help us stuff the stocking - write the mailing list with your suggestion of a little language you’d like to show us! Plan to take no more than 15 minutes (and less if you prefer); anybody can do that!

Commitments so far:

Mailing list

We have a mailing list that we use for occasional discussion, but usually just monthly meeting reminders. It’s extremely low traffic and definitely the best way to know what is going on with the group.


We customarily meet on the !2nd Wednesday of every month from !7pm to !9pm in the back part of the main room at the Dayton Chess Club. The address is

18 W 5th St., Dayton, OH 45402

The telephone contact is 937-461-6283

Here’s a map. Sometimes parking is hard to find, though all the metered spots are free after 6pm. If you’re lucky, you can find parking on 5th street in front of the building. There is also usually parking on a (sadly unmarked on all of the online maps we could find) road that goes between 4th and 5th street between Main street and Ludlow.

Larger Map

Earlier reports about being unable to use the Chess Club on Wednesdays turned out to be wrong (or at least premature)! So our meeting place remains unchanged, but keep an eye on the mailing list in case of future changes.


We typically walk over to the Spaghetti Warehouse (a few doors west of the Dayton Chess Club) for dinner & conversation after the meeting. You’re welcome to come.
