Following up my presentations from JAX London, I was interviewed about Groovy for JAXenter, with questions about what Groovy brings to Java developers, the recent surge in popularity as Groovy broke the TIOBE index top 20 languages, my favorite projects in the Groovy ecosystem.

C’est l’été, il fait très chaud, et j’ai plein de menthe dans mon jardin… d’où l’idée de faire un dessert rafraîchissant : une glace à la menthe maison ! Un petit problème aussi : je n’ai pas de sorbetière, donc il faut faire sans ! Alors que nous faut-il : 25 cl de lait une bonne grosse poignée de feuilles de menthe fraîche 2 oeufs (2 jaunes et 2 blancs) 60 g de sucre en poudre, ou idéalement sucre glace (10 g + 50 g) 25 cl de crème liquide (non allégée) 1 pincée de sel Tout d’abord, il faut laisser infuser la menthe dans le lait, dans une casserole, pendant une bonne vingtaine de minutes, à couvert, sans faire bouillir le lait.

I recently came across InstantServer.io, a nice little service that allows you to instantiate an Ubuntu server for testing, for 35 minutes, on Amazon EC2. You click on the green button, and you’re given an account and a password, as well as the details to connect onto the machine through SSH. Please note that the service seems to be victim of its success, as requesting a new server takes more and more time it seems. Read more...

On the Groovy project team, we were wondering about which base JDK to support. So far, even the latest and greatest Groovy (version 2.1.4 just released today), we still support JDK 5 — despite being an End-of-Life’d product for a long while already. At conferences, I often ask the question on which versions of the JDK attendees are using, locally and in production, and it seems that JDK 5 has almost totally vanished off the face of the planet, but despite JDK 7 being quite mature now, it’s still JDK 6 that’s more widely deployed.
