Which programming language comes to mind when you hear Android app development? Most probably, you will immediately think of Java. This is because of the vast number of Android apps that are developed in Java.
Developers around the world are still wondering if Kotlin has any future or not. But with the introduction of Kotlin in Google I/O two years back, Kotlin has made its own place in the Android application development market.

Automated tests are a key component of continuous integration (CI) pipelines. They provide confidence that with newly added check-ins, the build will still work as expected. In some cases, the automated tests have the additional role of gating deployments upon failure.
The Apache Spark + Alluxio stack is getting quite popular particularly for the unification of data access across S3 and HDFS. In addition, compute and storage are increasingly being separated causing larger latencies for queries. Alluxio is leveraged as compute-side virtual storage to improve performance. But to get the best performance, like any technology stack, you need to follow the best practices. This article provides the top 10 tips for performance tuning for real-world workloads when running Spark on Alluxio with data locality, giving the most bang for the buck.
High data locality can greatly improve the performance of Spark jobs. When data locality is achieved, Spark tasks can read in-Alluxio data from local Alluxio workers at memory speed (when ramdisk is configured) instead of transferring the data over the network. The first few tips are related to locality.
Today we’d like to share a little speedy motion effect with you. The idea is based on the Dribbble shot Ping Pong Slow Motion by Gal Shir where you can see a ping pong ball being shot from one racket to the other. The motion in the animation is enhanced by squeezing the ball and making some background stripes’ height pulsate. This is exactly what we want to do in a slideshow transition: we’ll squeeze the image and add some background effect. Additionally, we’ll make the letters of the title fly away consecutively.
The animations are powered by TweenMax.
The grain texture for the background was generated using Grained by Sarath Saleem.
The slideshow shows a image in the center of the page:
When clicking on “next” or “previous”, the image will move away, being squeezed to create the illusion of a fast acceleration. The letters will fly away and the background shapes will start “pulsating”.
We hope you enjoy this little effect and find it useful!
