Hello everyone, Knoldus organized a session on 05th January 2018. The topic was “Understanding Spark Structured Streaming”. Many people attended and enjoyed the session. In this blog post, I am going to share the slides & video of the session. Slides:
Hello folks, hope you are doing cool, so lets start what is this “Feedback” app, earlier days i was wondering how companies, institutes and groups are taking feedbacks from attendees or users. Generally we at Knoldus and others (not all, may be some of them using better or other approaches) follow some standard ways like, sending feedback forms to them or asking them to fill Continue Reading
Knoldus organized a KnolX session on Friday, 23 September 2016. In that one hour session we got an introduction of Apache Spark 2.0 and its API(s). Spark 2.0 is a major release of Apache Spark. This release has brought many changes to API(s) and libraries of Spark. So in this KnolX, we looked at some improvements that were made in Spark 2.0. Also, in this KnolX we got an Continue Reading
Knoldus organized a KnolX session on Wednesday, 13 April 2016. In this KnolX session, we explored the different methods of writing unit tests for Spark applications. This session also talks about how unit testing of Spark applications is done, as well as tells about the best way to do it. This includes writing unit tests with and without Spark Testing Base package, which is a spark Continue Reading
The term Extreme Programming (XP) was coined by Kent Beck, in late 1990s. The purpose behind inventing XP was to find a way to deliver high quality software, developed by small teams, and to keep up with the changing requirements of customer. Although, XP is more than a decade old now, it is still being practiced by a lot of developers around the world. The following slide deck and Continue Reading
Last week, We have created a simple Employee-Self-Service application using Play Framework and Anorm SQL data access , which has CRUD facility. Now we have added more features, i.e. Handling asynchronous results with time-outs facility thus application is now reactive (Async + Non-Blocking) Play and Scala-based template engine implementation. Bootswatch-Yeti with Twitter Bootstrap 3.1.1 to improve the look and feel of the application Application screens: 1. Continue Reading
Akka allows us to write concurrent, fault tolerant and scalable applications. We recently migrated our product from Akka 1.3x to Akka 2.x. The new version is quite different from 1.3x versions. It is not merely an API change but an overall change. We have to also think differently to develop applications. This session was presented at Knolx Session at Knoldus. This talk gently introduces Akka Continue Reading
As multi-core becomes a standard, writing code which can harness the power of the cores remains a formidable challenge. The following KnolX session, tried to decode how scala is trying to give us an advantage by providing us parallel collections. It also discusses, which scenarios lend themselves to parallel processing and discusses the pitfalls of others.
