Philly ETE 2015 #35 – Ritchie S. King – Visual Storytelling with D3: A Conceptual Introduction to Visualizing Data with JavaScript

If you’re interested in visualizing data on the Internet, the best way to do it is to use the JavaScript library, D3. Short for data-driven documents, D3 works by marrying your data to your web page, a glorious union that enables you to sculpt that web page into a graphical display which mirrors exactly the structure of your data.

Philly ETE 2015 #34 – Yehuda Katz – What is Rust?

You may have seen Rust on Hacker News, Reddit or Twitter, but what is all the hype about? With Rust just recently having become stable, now’s a great time to learn more about this emerging language that is taking on old stalwarts like C++ without giving up on the expressiveness of higher level languages. Whether you’re a grizzled systems programmer or a dynamic language programmer looking to dip your toe in, this talk will have something for you.

Philly ETE 2015 #33 – Todd Montgomery – The Changing Face of Communications: IoT, REST, and Reactive

We are experiencing a profusion of interconnected devices. Architectures are undergoing radical changes to enable better scaling and resiliency. And at the heart of all of these are several new protocols that are changing the way services communicate. A lot of interest lies with WebSocket, HTTP/2, CoAP, MQTT, XMPP, etc. What can these protocols do? What can we learn from them? And where are things going? This session will explore these questions and more.

Philly ETE 2015 #31 – Brendan McAdams – A Skeptic’s Look at scalaz’ “Gateway Drugs”: A Practical Exploration

In this talk we will look at some of the “gateway drugs” of scalaz: Validation, NonEmptyList, \/, Monad Transformers, and more. How do they work from a practical standpoint? What is their value for real world applications? Can we use them without an advanced Maths PhD? And just how fun is it to *really* code with these tools?

Philly ETE 2015 #29 – Jan Machaček & Martin Zapletal – Implementing Exercise Wearables Analysis with Spark and Akka

Languages like Scala are making it easier to implement systems with distributed domains and distributed computation. Deployment, monitoring and operation of such systems is often neglected, left to the last moment. Jan will show how architect and implement your system with DevOps in mind right from the start.

Philly ETE 2015 #28 – Stuart Halloway – Enhancing Datalog for Datomic

Datalog is a deductive query system combining a database of facts with a set of rules for deriving new facts from existing facts and other rules. Datalog has been a signature feature of Datomic since day one, and the 2015 releases of Datomic add additional expressiveness for hierarchical selection, disjunction, and negation. In this talk, we will cover the basics of Datomic Datalog, and then dive into the latest enhancements, both in the core language and in how Datalog fits into application code.

Philly ETE 2015 #27 – Stuart Halloway – core.async: Concurrency without Callbacks

In this talk, we will cover the design of core.async, and then move directly to exploring core.async’s capabilities. Finally, we will assemble these primitives into substantial working programs, building toward the Holy Grail of async: substantial UI application development in the browser, with no callbacks in sight.

Philly ETE 2015 #26 – Soumith Chintala – The Deep Learning Revolution: Rethinking Machine Learning Pipelines

In the last decade, a class of machine learning algorithms popularly know as “deep learning” have produced state-of-the-art results on a wide variety of domains, including image recognition, speech recognition, natural language processing, genome sequencing, and financial data among others. What is deep learning? Why has it become so popular so quickly? How can one fit deep learning into existing pipelines?
