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.
I had recently come off of a three year contract and found myself with some time on my hands. I was interested in working on an application that interfaced directly with some sort of small device. The director of our company, Don Coleman, had done a good bit of work with small devices so I spoke to him about the possibility of building a small application around those devices. He agreed to it and offered to assist from the hardware end. Our director of training, Ken Rimple, was researching the Angular 2 JavaScript framework at the time and offered to build the UI for the application. We eventually decided that we would build a demo to display at our booth at the 2016 South by SouthWest conference. This post explains our approach and some lessons learned.
In today’s world of exploding big and fast data, developers who want both streaming analytics and ad hoc, OLAP-like analysis have often had to develop complex architectures such as Lambda—a path for fast streaming analytics using NoSQL stores such as Cassandra and HBase with a separate batch path involving HDFS and Parquet. While this approach works, it involves too many moving parts, too many technologies for ops, and too many engineering hours. Helena Edelson and Evan Chan highlight a much simpler approach to combine streaming and ad hoc/batch analysis using what they call the NoLambda stack (Apache Spark/Scala, Mesos, Akka, Cassandra, Kafka), plus FiloDB, a new entrant to the distributed-database world that combines streaming and ad hoc analytics.
