PLDI 2016: June 13 - 17, 2016 in Santa Barbara, California"PLDI 2016" is the 37th annual ACM SIGPLAN conference on Programming Language Design and Implementation. This is the premier forum for all areas of programming language research, including the design, implementation, theory, and efficient use of languages. PLDI’s emphases include innovative and creative approaches to compile-time and runtime technology, novel language designs and features, and results from implementations.
Strange Loop 2016: September 15-17, 2016The Strange Loop conference will take place at the Peabody Opera House in St. Louis, Missouri, on September 15th-17th, 2016. The 15th is an optional, preconference day; most preconference events require pre-registration and an additional fee. This conference presents an opportunity to make connections with the creators and users of the languages, libraries, tools, and techniques at the forefront of the industry.
International Conference on Functional Programming, September 18th-24th, 2016ICFP 2016, which will take place in Nara, Japan, provides a forum for researchers and developers to discuss the latest work on the design, implementations, principles, and uses of functional programming, covering a wide spectrum of work, from practice to theory, including their peripheries. Look here for more details.

NY Open Statistical Programming Meetup, March 16th, 2016On Wednesday, March 2016 at 6:30 pm, Devon McCormick gave a talk titled "Introductory Survey of Bayesian Methods Considering Dynamic Linear Models" at the offices of eBay, NYC, at 625 Sixth Avenue, 3rd floor. The talk covered the basics of Bayesian statistics with examples and demonstrations. Code in R and J was presented to illustrate basic Bayesian probability calculations. Additionally, the talk touched on a number of areas where Bayesian methods are applied, including Bayesian networks and Markov-chain Monte Carlo methods, but with special attention to Dynamic Linear Models for forecasting. Look here for slides (pdf) from the talk and here for links for further exploration of the topics mentioned.
