One of the things I am fortunate enough to get involved with on occasion is the Oracle Groundbreakers Podcast (previously known as the Oracle Developer Podcast) and something I have written about in the past, even as Oracle Developer Community (ODC) Appreciation Day post.

As a result of the recent Meetups on the subject of Helidon that have been occurring recently, we made the suggestion that Helidon be the subject of a Groundbreaker’s Podcast, net result I was invited to be part of the panel.  The podcast was recorded a few weeks ago, and know available (here). Go check it out, as it includes the key contributors to the project Dmitry Kornilov and Tomas Langer.

Another Spring means another excellent Oracle EMEA PaaS Forum for Oracle partners. Every Year Juergen Kress organizes the event, finding really nice venues to host several hundred people over four and half days.

The event is split into several parts,  Monday afternoon normally involves Oracle Ace’s presenting on best practices, insights on applying the various technologies etc.  For me this meant presenting on the London Developer Meetup, looking at how it worked, what has been successful, and what hasn’t.  For those know have read my blogs on the subject (here) will know about our Drone initiative.

Then Tuesday is a single stream day where Juergen has managed to pull in SVPs and Senior Product Managers from around the globe to provide a high level views of what has been going on with their products. For anyone consulting in the Oracle domain this is incredibly useful. For example there is a clear strategy coalescing around AI and Machine Learning both as a service proposition to users, but also how these technologies are being made available and used within other products.  Other areas such as OIC and SOA CS have stability and maturity, and the road map is about maximising connectivity with the newer products.

But before the sessions start, Juergen starts with opening remarks, and demos’ something engaging.  In previous years this has been things like Digital Assistants/Chatbots and so on.  This year, we have been fortunate to be an active contributor by demoing the drone through the use of APIs and talking about the ideas.  The dry runs of the demo on Monday went without problem, but when it came to the main show, the drone was a little uncooperative – we think because the air-con had really kicked in.  But importantly, even not achieving the desired result, the message of engagement made it home.

Wednesday is split into streams with in-depth sessions from the different Product Managers, he amount of insight gained from these sessions is tremendous, some of which is very much protected by safe harbour statements or not for public disclosure such is the honest and open discussions. The day closes with an Ace Director initiative which demonstrates the application of Oracle Cloud products to a plausible use case, and Luis Weir (Capgemini Oracle CTO) is part of. This session has become something of a tradition now.

The day’s business concludes awards, and for a second year the UK Capgemini team have taken home two awards for APIs and PaaS Contribution.

The final two days are then a choice of Hackerthon or 1/2 day training sessions on different products with the relevant Product Managers, and an excellent opportunity to pick the brains of the presenters as well as get hands on experience with the different products.

The week isn’t without it’s social and networking activities of course …

Oracle Developer Meetup – London Feb 19

Last night was the first Oracle Developer Meetup in London for 2019.  We were very fortunate to have Tomas Langer fly over to talk about the new micro container/framework being developed as an open source solution by Oracle.

Oracle Developer Meet-up - Tomas Langer presenting on Helidon

Tomas, opened by explaining the evolution of the micro-profile being championed by the Eclipse Foundation who are now the guardians of J2EE also known as Jakarta and how the J2EE and Micro-Profile standards compare (in simplistic terms – micro-profile is J2EE stripped back to be simple and support what is typically needed in a microservice world).

The presentation then went onto compare Helidon SE and Helidon MP (micro-profile).  What was really pleasing is that with a couple of exceptions everything that Helidon MP can do, can be done in the SE edition, the difference being that for SE you have to implement more code, rather than the auto-magic of annotations, but in return you have a Reactive Java platform with a development paradigm which relates to JavaScript Express.

In addition to talking about what can be done, Tomas described the kinds of features being developed, this includes:

  • Bringing micro-profile support up to the very latest specification,
  • More reactive persistence technologies support,

With the scene set, Tomas then worked through a series of live code scenarios starting with a clean slate and building Hello World in both the SE & MP models illustrating the differences in approach.  This was then built upon to add the following capabilities:

You can get the complete example which uses Helidon in both configurations from Tomas GitHub.

In addition to Helidon itself on GitHub, there resources provided include rich documentation and examples of each key feature.  Plus a Slack community, that if you contact any of the Helidon team will get you invited allowing you to discuss with the development team how to do things along with other developers using Helidon.

Tomas can be contracted via @Langer_Tomas.  Helidon project also has its own Twitter account – Helidon Project

Helidon itself can be found at:

I have previously blogged on Helidon at Exploring Helidon – Part 1

#OracleDevMeetup in London - GraphQL

Last night we ran the latest of the Oracle Developer Meetups in London. This time Luis Weir presented on GraphQL, which got an very engaged discussion about the strengths and weaknesses of GraphQL, in-depth points about how the error paths should be handled among many other things.

The presentation material Luis used is based upon his Devoxx session earlier this year and can be seen here:

The links to Luis’ examples can be found on his GitHub account – https://github.com/luisw19/graphql-samples

After a insightful and thought provoking presentation on GraphQL the Drones with APIs project had its latest update.  Providing a lot of laughter to the evening’s proceedings. Including demonstration of flying the drone using REST APIs published via a gateway and Go back-end.  This included the DroneDash presenting a visual presentation of the commands being issues via REST, as seen here:

All the code, API definitions and documentation for people to add or extend can be found in the meetup’s GITHub – https://github.com/oracledeveloperslondon/.

A few of the useful links used or mentioned last night are:

 

The next meetup is planned for Monday November 19th.  Topics  will be published soon.

We have been fortunate enough to participate an ArchDev podcast about meetups – https://oracledevs.podbean.com/e/pizza-beer-and-dev-expertise-at-your-local-meet-up/

The podcast talks about the differences between the meet-ups and events such as conferences, what we try to get out of a meetup and the effort put into arranging them.

For more info about the meetup I help organise checkout out https://www.meetup.com/Oracle-Developer-Meetup-London/events/249256400/

We’d also like to thankyou Jurgen Kress and his team for all the behind the scenes work that means the London Dev Meetup events can happen and ensure all are suitable feed and watered.

Another month and another Meetup.  Last night was the quietest session we’ve had. But then we covered Identity Management and whilst the subject is so important it isn’t too popular.

Tanks to Atul Kumar for taking on the task of presenting on this subject.  You can find out more about Atul at:

Last night was the 2nd London Oracle Developer meetup with 100 people registered and  CTO Luis Weir presented on 3rd generation APIs which included their relationship to microservices. The outcomes was not only a excellently delivered presentation with an enaged audience, but led to some really thought provoking discussions, particuarly on the application of microservices in financial  contexts.  For example is it possible for for financial institutions to get near the post child Netflix in terms of building and delivering solutions to production given the certification and compliance requirements? Some interesting insights on PSD2 (Payments Service Directive 2)  as well.  Are questions like is a monolith wrong?

Screenshot 2018-03-06 14.27.26In addition to the high level architectural debate the evening included a shortened walk through on the possibilities of deploying the API Gateway and its relative ease compared to other products.

Finally we concluded with an update on the project that we’re running as an underlying theme for some of the meetups – that of using variuous tech to command the drone(s) via a set pf published APIs.  This included a call to arms to contribute eith to building your own apps to use the API or contribute to the back end as the solution gets built using an API  1st approach.

1st London Oracle Developer Meetup

Meetup Dec 17-1Monday night (18th December) I co-hosted with Luis Weir the first London OracleDeveloperMeetup. Despite being a Monday evening in the run up to Christmas where a lot of people will attending Christmas events, needing to finish present shopping or event started their holiday we still had a tremendous turn out. With nearly 50 people out of almost 100 registrations coming to the Oracle London Office.

The evening kicked off just after 6pm with beer, pizza and time for people to Network. At 7pm we started with what had been scheduled to be two short 25 minute presentations to share insights into API design best practices and an overview of Apiary. Such was the interest,  interaction and conversation in the subject and content that the session over ran. But here in lies one the benefits of a Meetup over things like conferences. In the Meetup the is space and time for the presenters to adjust to what the attendees wish to cover rather than beholden to the venue scheduling.

Picture1With the presentation and discussions finding a suitable pause, it was an opportunity for a  call to arms to be made, and for people to try using developing APIs. With a mission defined which we hope people will try to continue with as it will contribute to the next Meetup. You don’t need to have attended last night’s event to participate in the next Meetup. If you want see what we’re going to try achieve take a look at the end of the slide deck. We think it will be be very entertaining and the source of a lot of laughter and amusement.

Some people did take up the challenge, others took it as an opportunity to talk further about the technology or just network.

We have now setup a GitHub so that people can contribute to the development of the API ready for the next event (https://github.com/oracledeveloperslondon/droneAPI­).

If you would like to see what is being tweeted about the event checkout #OracleDeveloperMeetup on twitter.

Photos can be seen here.

We hope you will join our Meetup and register for the event when we announce the final details. In the mean time give Apiary a try, share with us the API you have designed.
