InfoQ recently released a video from the APIDays conference that took place in Paris last year. I talked about scaling an Open API based web API using Cloud Endpoints, on the Google Cloud platform.

I spoke about the topic a few times, as web APIs is a topic I enjoy, at Nordic APIs, at APIDays, or Devoxx. But it’s great to see the video online. So let me share the slide deck along with the video:

Time flies! Last week was my first “Googleversary”: It’s already been a year since I joined Google Cloud as a Developer Advocate. What a ride it’s been so far!

I announced my move to Google in June last year. And since then got the chance to:

• talk at more than 20 conferences or meetups
• give 3 keynotes
• write 36 articles
• meet with a dozen customers or so
• addressed literally thousands of developers

For some conferences, like Devoxx Belgium, I even spoke 5 times! Or for my trip to Singapore, I had 6 talks or workshops lined up!

Apache Groovy is coming up with a new parser, that supports the Java 8 syntax elements, as well as some new notation and operators of its own (like !in, !instanceof or ?[] for safe navigation with collections, or with ?= for Elvis assignment). I blogged recently about the fact that you can try this new flavor online on this forked Groovy Web Console version, without the need of installing everything. But today I’ll tell you how to build it for yourself in order to run it on your machine.

In two weeks, I’ll be flying east, much further east than I’ve ever been! I’ll visit Singapore! And I’ll have a pretty busy week with several events: conference, meetup, user groups, brown bag lunch… and I’ll talk about Groovy, Machine Learning, and chatbots!

First of all, on Wednesday 31st, I’ll participate to the Singapore Java User Group, where I’ll give an update on Apache Groovy (the latest improvements, new features, the roadmap).

A new Java 8 runtime for Google App Engine standard is coming soon, and is currently in alpha testing. You can request to join the alpha program, if you want to try it out for yourself. But I wanted to let anyone play with it, easily, to see how well the Java 8 APIs work, but also to try some Java 8 syntax too. So here’s a web console where you can do just that!

You know what? It’s Pi Day today! Well, if you follow the American date standard, it’s 3.14 today, a nice approximation of Pi. Last year, in a past life, I had played with Pi already, but this year, my awesome colleagues (Ray, Sandeep, Francesc, Ian) have been working on some very cool demos around Pi, with the “Pi delivery”, at https://pi.delivery/

You can transform the Pi digits in a nice melody, show a D3.js based visualisation of the transitions between digits, you can stream the Pi digits, and more. And you can learn about how it’s been developed on the Google Cloud Platform.

Today was announced the general availability of Google Cloud Endpoints!

Endpoints is the Google Cloud Platform solution for Web API management, which lets you easily protect & secure your API, monitor it, without overhead, and even allows you to implement your API with any language or framework you want.

I’ve spoken about Endpoints a few times already, at Devoxx Belgium, Nordic APIs summit, and APIDays Paris. And you can see the recording of my Nordic APIs appearance, if you want to learn more about Cloud Endpoints:

For Google Cloud Next and Devoxx France, I’m working on a new talk showing how to build a conference assistant, to whom you’ll be able to ask questions like “what is the next talk about Java”, “when is Guillaume Laforge speaking”, “what is the topic of the ongoing keynote”, etc.

For that purpose, I’m developing the assistant using API.AI. It’s a “conversational user experience platform” recently acquired by Google, which allows you to define various “intents” which correspond to the kind of questions / sentences that a user can say, and various “entities” which relate to the concepts dealt with (in my example, I have entities like “talk” or “speaker”). API.AI lets you define sentences pretty much in free form, and it derives what must be the various entities in the sentences, and is able to actually understand more sentences that you’ve given it. Pretty clever machine learning and natural language process at play. In addition to that, you also have support for several spoken languages (English, French, Italian, Chinese and more), integrations with key messaging platforms like Slack, Facebook Messenger, Twilio, or Google Home. It also offers various SDKs so you can integrate it easily in your website, mobile application, backend code (Java, Android, Node, C#…)

The schedule for Google Cloud Next was unveiled this week, and there’s lots of interesting sessions to attend. With the many parallel tracks, it’s difficult to make a choice, but I wanted to highlight some of the talks I’d like to watch!

The Google Cloud Platform is a pretty rich one, with many options for your compute needs. How do you choose which one is best for your use case? Brian Dorsey covers this in detail in this session:

The purpose of this article is to deploy a Ratpack web application on Google App Engine Flex.

For my demos at conferences, I often use frameworks like Ratpack, Grails or Gaelyk, which are based on the Apache Groovy programming language. In a previous article, I already used Ratpack, but on a slightly more complex use case, but this time, I want to share a quick Ratpack hello world, and deploy it on Flex.

I started with a hello world template generated by Lazybones (a simple project creation tool that uses packaged project templates), that I had installed with SDKman (a tool for managing parallel versions of multiple Software Development Kits). But you can go ahead with your own Ratpack apps obviously. Feel free to skip the next section if you already have an app.
