We will talk about Spotify’s story of migrating our big data infrastructure to Google Cloud. Over the past year or so we moved away from maintaining our own 2500+ node Hadoop cluster to managed services in the cloud. We replaced two key components in our data processing stack, Hive and Scalding, with BigQuery and Scio … Read More
Property-based testing is as close to a panacea as we are likely to get in the software industry. Whether you’re someone who loves writing tests or someone who finds testing tedious, identifying and testing the properties and invariants of your code can produce more useful (and more interesting) tests. This talk will briefly cover what … Read More
Keeping up with the pace of change in emerging technology is an ever present challenge for enterprises. Trying to build systems that age and evolve gracefully over time is not a small task. We are all familiar with frameworks that help us implement architectural patterns, especially application architecture. In this session we will investigate Lagom, … Read More
This past Tuesday I had the pleasure of attending the Scala by the Schuylkill conference at Comcast headquarters in downtown Philadelphia. Initially begun as an internal Scala conference, the organizers opened the conference this year to external folks interested in Scala. I learned a lot from this event, gaining perspective on trends in the Scala community and sparking curiosity in several interesting applications of the Scala language.
Backpressure Food for thought Very simply put, the idea behind backpressure is the ability to say "hey slow down!". Let's start with an example that has nothing to do with software: Imagine you own a factory that produces doughnuts (lucky you!) and just signed a contract with the largest grocery chain in the Northeast US. … Read More
This is a continuation of my Internet of Things with Scala posting. In this installment I will go over the assembly of the device that will be used to capture the soil moisture data and send it to an MQTT broker so that it may be picked up by the Scala/Akka based application. The Parts … Read More
Last week, Lightbend (formerly Typesafe) received a cash infusion of $20M from investors (see announcement here). At Chariot, we are happy for our partner. More than that, we believe that it signals a growing trend of the importance of the convergence of IoT, mobile and the collection and use of data in real time. IDC … Read More
There has been a great deal of buzz around the Internet of Things lately. The advent of small inexpensive devices and in particular the Arduino has inspired a generation of people with no background in electrical engineering to do some very creative things. I myself was first inspired by the Arduino and had built several … Read More
To take full advantage of Java 8’s support for lambdas and interfaces with concrete methods, a lot is changing behind the scenes of the Scala 2.12 compiler! In this session, learn what’s changing.
Scala is famous in part for having one of the richest type systems of all mainstream programming languages today. Despite its reputation, Scala’s type system remains one of the most under-documented and jargon-heavy aspects of Scala. This talk will turn the academese into English, providing an example-rich tour of Scala’s type system, covering all the things that make people call it “powerful”. This talk isn’t about showcasing a bunch of challenging little logical puzzles with types; on the contrary, this talk is about showing practical uses of Scala’s type system, making it work for you and your users.
