#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.

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.

The slides are here:

 

OracleCode London 2017

My colleague & boss Ace Director Luis Weir and I were invited to present at Thursday 20th’s Oracle Code London.

oracle_codeThe request to present came late as we where needed to cover someone who had to cancel (not that we aren’t grateful for the opportunity). This did mean getting the presentation together was a little bit of a scramble, unfortunately I missed a couple of sessions as I needed to assemble an environment, work out how I wanted to explain the point Luis’ slides where communicating as this was the first time presenting with Luis as a double act. Add to that address the day to day work demands.

Despite these challenges, I think the presentation went very smoothly (and we’re looking forward to receiving the feedback). The slides can be found here …

I did catch a few presentations, including the keynote by Adam Bien, Tim Hall‘s presentation on exposing databases using REST services, Lucas Jemella‘s microservices and eventing backbone and finally CQRS by Sebastian Daschner. All presentations  where all top notch, loaded with useful information.  I’ve been fortunate to see both Lucas and Tim presenting before so knew I would in for a really good presentations.  So if you ever want to know about Oracle DB stuff with practical honest insights I’d recommend looking Tim up.  Like wise in the middleware space for Lucas.

Seeing the presentations and different presenting styles was interesting. Those presenters with a Java Rockstar background vs those from an Oracle Ace background. The Java guys taking a very minimalist (if any) slides and all code / demo – but blink and you’ll miss it, where as the Ace community (of which I am fortunate enough to be a member) with slides that are often visually very strong and still supported by demos.

Whilst I’ve attended Oracle Open World, I’ve not yet seen the parrallel Java One conference in San Francisco. That said, the feel of the day’s event (and presumably the goal) is what I’d expect Java One to be like. I have in the past attended similar RedHat events, whilst the venue has a similar feel (not unsurprising as both have used SkillsMatter venues), what was different between the Oracle and RedHat events was that the atmosphere felt a lot friendlier and communial at Oracle Code. This maybe down in part to the fact that I know more of the people both Aces and Oracle employees, although that can’t be the only reason as when I was involved in the RedHat environment I had known senior people within the organisation and encountered presenters.

My last observation, more technical is the fact that JavaEE was mentioned a lot more than I’d expected, even those much maligned EJBs got a mention. Is JavaEE making a reassurgence?

So, if you get a chance to attend OracleCode – as an architect or developer I’d recommend that you take the opportunity. Whilst Devox maybe bigger with the really big name speakers, the day was both informative, engaging and rewarding.
