April was definitely my crazy Speaking Month. After an almost one year long self-imposed conference hiatus, I was challenged to deliver four different talks, attend two discussion panels, give one live demo and release one interview. All in a three weeks period span. First I went to PyCon Sette in Florence. A few days later a plane took me to St. Petersburg, Russia, for PiterPy. Finally, the next weekend I was in Rome for the Western Europe Microsoft MVP Community Day. In the meantime several Channel 9 TecHeroes episodes were due for release. This was of course super exciting. And challenging. ...

Today I released Eve 0.6.2. It includes many fixes and improvements over the previous releases. Areas addressed are CORS management, soft deletes, token authentication, oplog, data validation, and others. Please see the changelog for details. Work on v0.7 is also ongoing. It will include new features such as support for the MongoDB Aggregation Framework (docs) and a few breaking changes, so you might want to check it out in advance. Special thanks to Arnau Orriols, Cyril Bonnard, Hamdy, Luca Di Gaspero, Manquer, Nick Park, Patrick Decat, Prayag Verma, Ralph Smith, Stratos Gerakakis, Valerie Coffman and Wei Guan who contributed to this release. ...

There is a new episode up at Channel9 TecHeroes. It is called Real Life .NET Cross Platform and it is about developing production-ready, cross-platform applications with today’s .NET. In the interview we talk about SimpleCache, an asynchronous, permanent and cross-platform key-value object cache powered by SQLite3. The project is still a work in progress so there is no NuGet package available yet, but it is quite usable already. The talk slides are also available. ...

I was recently interviewed at Channel 9 TecHeroes. Topic was CoderDojo, the network of free computer programming clubs for young people. The show is run by Microsoft Italy, so the interview is in Italian. Enjoy the show.

A few hours ago I was notified that I have been awarded with the Microsoft MVP Award for Development Technologies. This came totally unexpected. Especially so considering that during the last few years I have been splitting my time between Microsoft and other open source technologies. My public work has mostly been on Python and MongoDB. Yes I also released .NET open source projects in the meantime (more are coming soon) and yes, I wrote a few articles here and on the MSDN Blog, attended Microsoft events and did interviews. But really, I did not expect these activities to have an impact. This is probably why only a couple minutes from learning about the award I was suffering Impostor Syndrome symptoms. ...

A new version of Eve, the REST API framework for Humans, has been released today. Following the 0.6 milestone released one month ago, v0.6.1 introduces some fixes and few new important features. Upgrade is strongly encouraged. As always, a changelog with full list of updates is available.

The slides of my talk at Percona Live 2015 (Amsterdam) are online. It was titled “MongoDB and REST APIs a Match Made in Heaven” and it was meant as an introduction to Mongo, REST principles and the Eve python framework. Overall it has been a pleasant experience, although I found that splitting 300 attendees through seven concurrent tracks ultimately led to too much fragmentation. People often found themselves with 2-3 interesting talks all happening simultaneously, and just had to pick one. ...

On Stack Overflow and the Eve mailing list, but also in my mailbox and even on Twitter, I get a lot of enquiries on how to build custom endpoints within a Eve-powered RESTful application. Now, since within Eve all endpoints are fully customizable, what they really mean is: How do I setup endpoints without any binding to a data entity, just connected to a custom method? They would like to call something like /mycustomendpoint and get the response from a method they have defined somewhere in the Python sources. The standard endpoint-entity mapping provided by Eve covers 90% of their needs, but sometimes they just need endpoints that have nothing to do with data entities. ...

FatturaElettronicaPA has just been updated to v0.1.4. With this release invoice bodies (FatturaElettronicaBody items) are also validated. As always, you can install the package directly from NuGet. See the original post for more info. Also don’t forget to check the related projects. Update: v0.1.6 has also been released.

A few days ago Cerberus 0.9 was released. It includes a bunch of new cool features, let’s browse through some of them. Collection rules First up is the new set of anyof, allof, noneof and oneof validation rules. anyof allows you to list multiple sets of rules to validate against. The field will be considered valid if it validates against one set in the list. For example, to verify that a property is a number between 0 and 10 or 100 and 110, you could do the following: ...
