Using QJson under Windows

Recently lots of people asked me how to build QJson under Windows. Most of them reported build/link errors, so I decided to try personally. The good news is that QJson can be successfully built under Window, I can show you proof ;) {% img /images/qjson/qjson_windows_1.png %} {% img /images/qjson/qjson_windows_2.png %} I have written the build instructions on QJson website: just take a look here. One last note: if you have problems with QJson please subscribe to the developer mailing list and post a message.

kaveau: easy and integrated backups solution for KDE

During the last week I had the possibility to work on anything I wanted, Novell’s hackweek is so cool :) I decided to dedicate myself to an idea that has been obsessing me since a long time. Last December my brand new hard disk suddenly died, making impossible to recover anything. Fortunately I had just synchronized the most important documents between my workstation and my laptop, so I didn’t lose anything important.

New QJson release

Gran Canaria Desktop Summit has been great and really productive. I had the pleasure to meet people interested in QJson, chat with them but also hack with them. In fact we hacked a lot, doing lots of changes to QJson: the API has been cleaned, now it can be considered stable unicode support has been completely rewritten it’s now possible to convert QVariant objects into JSON ones So it’s with a great pleasure that I announce the release of QJson 0.

rockmarble: see who is going to rock in your town

During the last weekend I hacked a bit on rockmarble and I added a new feature: retrieve all the events happening in a certain city. As usual data is provided by last.fm, which should return also the events _“near” _the specified city (don’t ask me to define a value for near :) ). I have created new openSUSE packages, this time everything should work fine. Just make sure to remove all qjson packages before installing this release (in fact all the previous problems were due to packaging errors of qjson, now I have created new packages called libqjson0).

rockmarble: how to follow your favourite artists tour with Marble

During the last weekend I wanted to have some fun with QJson. So I came out with this idea: retrieve from last.fm the tour dates of my favourite artists and display the locations using Marble. After some hacking I created this small application: rockmarble… If you have a last.fm account rockmarble will import your favourite artist list. Otherwise you can add one artists at a time. The tour location will be displayed inside Marble, using openstreetmap.

QJson: a Qt-based library for mapping JSON data to QVariant objects

In order to realize a project of mine I started looking for a Qt library for mapping JSON data to Qt objects. I came over a couple of solutions but none of them made me happy. So in the last weekend I wrote my own library : QJson The library is based on Qt toolkit and converts JSON data to QVariant instances. JSON arrays will be mapped to QVariantList instances, while JSON’s objects will be mapped to QVariantMap.

Ruby downloader for Jamendo

Also this year I’ll attend the Linux day (a day dedicated to Gnu/Linux and FLOSS that occurs every year in Italy) organized by my LUG. Guess what I’ll be talking about… ;) While organizing the event somebody proposed to setup a local server with some music released under CC license. He suggested to download some albums from Jamendo (due to network issues we won’t be able to provide direct access to the website).

Can dreams became true?

During the last years of university I spent some time wondering about my future job. After the degree I received lot of offers (fortunately also good ones), but none of them matched with my “dream job” . There was always something missing/different. I was just trying to convince myself that the “perfect job” can exist only in our dreams when my feed reader pointed me here. After reading these lines:

Still coding

Yes, long time has passed since my last post (really strange, isn’t it :D ). It has been a busy period, full of work, dog training and… coding (fortunately!). During this time I’ve been working on XesamQLib creation. This is a Qt based library for accessing Xesam services. Its API is going to be similar to Xesam-glib one and it will make life easier for developers who want to interact with programs exposing Xesam service (who talked about Strigi?
