In this article, I am going to show how to identify some common Spark issues the easy way: by looking at a particularly informative graphical report that is built into the Spark Web UI – the Web UI Stage Detail view.
A close look at the ways Spark ML models can be put into production, which patterns work best in which situations, and why.
Learn some key performance patterns and anti-patterns that will help you get the most out of Spark 2.0.
A hands-on tutorial using Spark SQL and DataFrames to retrieve insights and visualizations from datasets published by the City of San Francisco.
In this intermediate-level tutorial, I'll address the question of which Apache Spark APIs to use, with a series of brief technical explanations and demos that highlight best practices, latest APIs, and new features in Spark 2.0.
Overview of the Brillo (and Weave) stack, including an overview of the features provided by Google and how it compares to its parent system—Android. Recorded at DevFest MN 2016.
Bluetooth UUIDs can be a bit confusing at first, and there are some differences in how mobile platforms advertise these values that can lead to incompatibility problems in your application.
In this tour from QCon SF, I’ll show you Spark's ability to rapidly process Big Data. I'll demonstrate extracting information with RDDs, querying data using DataFrames, visualizing and plotting data, and show you how to create a machine-learning pipeline with Spark-ML and MLLib. We'll also discuss the internals which make Spark 10-100 times faster than Hadoop MapReduce and Hive.
Walkthrough of Google's Proximity Beacon API for beacon management and the Nearby Messages API for client-side discovery.
Applying the Page Object Model (popular with Selenium testing framework) abstractions to your Android automated tests helps produce logic that is reusable and easier to maintain.
NewCircle is pleased to announce our latest Android development course—Android Testing. Android Testing is a three-day course focusing specifically on tools and techniques to effectively integrate automated testing into your application development workflow.
Dan Bornstein fields live questions from the audience in this video recorded at a recent SF Android User Group event.
Video covering Spark Streaming from my presentation at the Philly Area Scala Meetup.
After you've fed some data into the Proximity Beacon API, how do you retrieve that information client-side when the mobile device observes your beacons out in the wild? In this article, we'll discuss how the Nearby Messages API provides the missing link to make this easy.
Google's Proximity Beacon API provides an abstraction layer for managing beacon deployments in the field. In this article, you will learn the basics concepts related to the Beacon API, and how to get an API project set up with Google.
Colt McAnlis presented at SF Android on using data compression to improve networking performance on mobile. He presents some practical methods that all application developers can use to make mobile data transfer easier on users.
Walkthrough of Google's Eddystone beacon formats, Proximity Beacon API, and the Physical Web from AnDevCon Boston 2015.
Video and slides from my full-day Apache Spark workshop training at Spark Summit 2015
Android 'M' includes a System UI Tuner developer option to control aspects of the status bar. We can also programmatically control this element from the shell or another application.
A presentation aimed at beginners who have heard about RxJava and want to see what all the fuss is about.
Google introduced some new customization hooks for device OEMs and partners starting with the Lollipop release of Android. Is this something you can take advantage of in your device builds?
Users are pretty excited about Android's new "doze" feature. Developers may have more mixed feelings on the subject. Either way, it's good for us to take a deeper look at how this feature works.
Android has finally introduced a runtime-granted permissions model. It will be some time before most applications are updated to take advantage of the new system, so how will this new system affect your application on user's devices before you've had a chance to update it?
Today, according to Dean Wampler, Scala has successfully taken over the Big Data world. This is a talk about why.
