Video: Introduction to Platform Agnostic Hybrid App Development

Mon, 2017-08-28 06:00

The way in which apps are being built is significantly changing; now even more so with the cloud and various platforms and devices that must be supported across organizations. Why write code for each platform or device when you can write once and deploy anywhere? In this on-demand Oracle Code Online session replay Oracle ACE John Sim, a consultant at Fishbowl Solutions, demonstrates how to use Oracle JET to build platform agnostic, re-usable HTML5 applications that can be run as a Desktop / Mobile App or within a browser.

This session was part of the Mobile Development track in the Oracle Code Online event held in June 2017. Other on-demand sessions in this track include:

Oracle Code Online also featured a Full Stack Web Development track, which included the following sessions, also now available for on-demand replay:





Point the Camera at Your Face: Where is Your 2 Minute Tech Tip?

Fri, 2017-08-25 06:00

The very first video in the community-driven 2 Minute Tech Tip video series was published on August 29, 2014. Since then 230 more 2MTT videos have been recorded and published, featuring insight and expertise from community members around the world, covering a wide variety of topics and technologies.

And now it's your turn.

Sharing your technical skill in a 2 Minute Tech Tip is easy. Got a webcam on your laptop? Got a smart phone? Either one will do the job. Just point the camera at your face (or vice-versa) and start talking. But instead of sharing the details of your vacation trip ("Hey! Does this look infected to you?"), you're going to share some of the technical skill you've accumulated as a software developer, solution architect, DBA, SysAdmin, or whatever.

Once you've recorded your video, send it to me. I take care of the rest.

As an alternative to recording your own tip, I can record you remotely via Skype.

Even better, if you're going to be at Oracle OpenWorld or JavaOne this year, I can record your tip in person. Just contact me to get on my schedule.

I'm also happy to share technical guidelines and other tips to help make your tip a good one.

So let's do this!

Video: Oracle Mobile Cloud Service Integration Options

Wed, 2017-08-23 06:00

Oracle Mobile Cloud Service (OMCS) might not be the first product you think of when thinking about integration, according to Oracle ACE Associate Maarten Smeets. "But it does have many useful options for integration."

As Maarten explains in this 2 Minute Tech Tip, for authentication OMCS can use third party SAML and JWT tokens, Facebook logins, Oracle Cloud accounts, or OAuth and basic authentication. OMCS can also deal with Beacon package formats including AltBeacon, iBeacon, and Eddystone. It can use Google Cloud Messaging, Firebase Cloud Messaging, Syniverse and other messaging services, "and it comes with client SDKs for Android, iOS, Windows Mobile, and plain JavaScript," Maarten says.

Maarten packs a lot more information into his short video. So check it out!

Video: Kubernetes: Finding the Magic

Fri, 2017-08-04 12:18

"It's one thing to say 'I want to use Kubernetes for my orchestration and for my application,'" says TJ Fontaine. "But  you can't just sprinkle some Kubernetes dust on it and get magic out of it. You actually have to do a little bit of work and understand how it all fits together." Fortunately, getting started with that work can be as easy as watching a video. In this case, the video in question is this short interview with TJ, recorded at the Oracle Code event in Atlanta on June 22, 2017.

TJ, a software engineer, leads Oracle's open source efforts for Kubernetes. In this interview he recaps his Oracle Code presentation, "Introduction to Kubernetes," discusses patterns and anti-patterns for using Kubernetes in your development projects, and explains why the abstract for his session contains only 15 words.

Video: Transport Layer Security in Oracle ICS and MCS

Wed, 2017-08-02 07:00

How secure is your connection to your Oracle Mobile Cloud or Integration Cloud service? In order to answer that question, Oracle ACE Associate Maarten Smeets, senior integration consultant with AMIS Services, suggests in his latest 2 Minute Tech Tip that you look at the various layers in the Open Systems Interconnection (OSI) model. Maarten explains that the data layer and segment or transport layer are particularly important. "The hardware layers are taken care of by Oracle since ICS and MCS are PaaS solutions. For security in the data layer you often see the use of Secure Token Services. Authentication takes place by a client and a token is returned. This token can be used for subsequent authentications and can be validated against the secure token service. Examples of this are SAML, JWT, and OAuth." Watch Maarten's tip for more detail.

Video: The Rise of ChatBots in Enterprise Mobile Application Development

Mon, 2017-07-31 08:16

Conversations between human beings and computers have been a mainstay of science fictions movies for decades. Remember the HAL 9000 in director Stanley Kubrick's groundbreaking 1968 epic "2001 - A Space Odyssey?" Remember Joshua, the computer in the 1983 hit "War Games?" Remember Kirk and Spock issuing verbal commands to the Starship Enterprise's onboard computer? In the second decade of the 21st century, conversational interfaces have transcended fiction to become a reality, and the next big thing in consumer and enterprise mobile application development. Paired with artificial intelligence, chatbots help to simplify mobile communication between users and services. As in human conversation, well-chosen wordings allow users to book a table in a restaurant, arrange a taxi to the airport, buy an airline ticket, and more. This on-demand session video from the Oracle Code Online event in June 2017 explores a developer perspective on chatbots.

Video: Making RESTful Web Services the Easy Way with Node.js | Dan McGhan

Mon, 2017-07-17 13:28

Drivers make it easy to connect to and run statements against a database. That means they're perfect for creating RESTful APIs, right? You'll want to add some pagination capabilities, maybe sorting controls, and perhaps some generic filtering options. You could do all that with the driver and some smart code, but is there an easier way?  In this video replay of Dan McGhan's session from the Full Stack Web track in the recent Oracle Code Online event, you'll learn about some of the challenges associated with manual API creation using drivers, and about several tools that offer similar functionality out of the box, including Loopback, Sails, and Oracle REST Data Services.

Video: Discover Graal: Open Source Polyglot Runtime Environment

Fri, 2017-07-14 08:27

Have you discovered Graal? It's a new open source project created by Oracle Labs. "Graal allows you to deploy virtually any language in a single environment and actually deploy multiple languages in that same environment," explains Scott Lynn in this interview. "So you can have a JavaScript front end that talks to an R back-end that's talking to a database, for example. And there isn't the normal requirement of creating, say, a JSON file to actually send a command over to the R engine and then have the R engine execute and send a JSON file back with the data in it. You can literally just transfer the objects back and forth, because they're in the same language environment."

Scott, director of product strategy for Oracle Linux, delivered the session "Polyglot Development and Deployment Through Language Environment Virtualization" at the Oracle Code event in Atlanta, GA on June 22, 2017. He took a break from prepping for his session to talk with me about Graal and invite developers to get involved in this open source project, available on GitHub. Watch the video!

BTW: Scott will present a session on Graal at the Oracle Code event in Sydney, Australia on Tuesday July 18, 2017. If you'll be in the neighborhood, there's still time to register.

Video: Microservices and Modern Software Development

Wed, 2017-07-12 07:00

Microservices are pretty much a done deal, according to Mark Cavage VP or Software Development for Oracle. "I think almost everybody out there admits that in some part of their organization they're going to build a microservices-based application. Across the board. That's a given." It's also a given that Docker is part of the plan. "Docker is the the fundamental technology used to encapsulate an application and ship it from laptop through testing through production."

Mark and his colleague Chad Arimura, also an Oracle VP of Software Develpment, stopped by the DevLIVE set at Oracle Code Atlanta to recap their keynote session, "Microservices: Where are We, and How Did We Get Here," and chat about containers, Kubernetes, Werker, serveless architectures, and a whole lot more.
