SimpleObjectCache is a very simple permanent, cross-platform, asynchronous key-value object cache for .NET. It comes with built-in SQLite 3 support. Alternative backends can be added by implementing the IObjectCache or IBulkObjectCache interfaces. How it works First, you need to set the ApplicatioName. This is also going to be the folder where your cache will reside. Depending on the host OS the location of this folder might be different. On Windows it would be something like C:\ProgramData\<ApplicationName>\SimpleObjectCache. ...

Released by the nice folks at Drud, EveGenie is a tool for making Eve schema generation easier. Eve’s schema definitions are full of features, but can take a good amount of time to create when dealing with lots of complex resources. From our experience, it’s often helpful to describe an endpoint in JSON before creating it as an Eve schema. This allows you to make quick decisions about the structure of your entities without spending time moving schema code around. This is where EveGenie comes in. ...

Quick note to let you all know that Eve v0.6.4 is out with a few significant updates. Thanks to James Stewart for contributing to this release. Work on v0.7, which will include MongoDB Aggregation Framework support (docs) and many other new features, continues steadily.

Eve-Swagger is a swagger.io extension for Eve powered RESTful APIs. It has been around for a while on GitHub but I never managed to officially release it. So rejoice! it is now available on PyPI. But what is Swagger, and why is it useful to your RESTful API? With a Swagger-enabled API you can get interactive documentation, client SDK generation and discoverability, all for free. From Swagger website: Swagger is a simple yet powerful representation of your RESTful API. With the largest ecosystem of API tooling on the planet, thousands of developers are supporting Swagger in almost every modern programming language and deployment environment. With a Swagger-enabled API, you get interactive documentation, client SDK generation and discoverability. ...

Cerberus is a lightweight and extensible data validation library for Python. Beta has been around since 2012. During this time Cerberus has been serving as the validation system for Eve core. It has been also adopted by a quite a lot open source projects, averaging around 18K downloads per month on PyPI and collecting some remarkable endorsements. All things considered, I would dare to claim that Cerberus is battle tested to death. This is, in fact, one reason why I believe that the time for a canonical and stable release has come. Another reason is that next release is a major one. It brings a ton of important new features along with very significant code refactoring and a redesigned, powerful API. Third, next release breaks backward compatibility, and we want to signal that in the version number. So next Cerberus release will be 1.0. If you have been following the development this will come as no surprise, as a Release Candidate has been out for a while. As a Cerberus user you will want to take the plunge and upgrade to 1.0 because well, it is just too cool to be true. If new to Cerberus you will also want to adopt 1.0 right away, for the same reason. If you are new however, make sure you get the basics covered before reading further. By the way, at latest PyCon Italy I gave a talk on Cerberus which also included a preview of several 1.0 features. You can check the slides to get a general idea of the tool, its usage, and upcoming features. Let’s now look at some of the relevant features and changes introduced with Cerberus 1.0. For a (mostly) accurate list of changes and new features, have a look at the changelog. ...

Ho appena pubblicato su NuGet l’ultimo aggiornamento di FatturaElettronicaPA, il package .NET per la compilazione e convalida delle fatture elettroniche per la Pubblica Amministrazione.

Per consentire il necessario adeguamento al nuovo regime di verifiche, fino al 31 luglio 2016 il mancato superamento di uno o più di questi nuovi controlli non comporterà lo scarto del file ma solo una segnalazione che verrà riportata all’interno della Ricevuta di consegna o della Notifica di mancata consegna. Dal 1 agosto 2016 i file che non dovessero superare uno o più di questi controlli verranno scartati. ...

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.
