RDFBeans 2.2: Now on GitHub

I am happy to announce that RDFBeans project had finished migration to GitHub and reached 2.2 version.

The most important change in this release is dropping dependency on RDF2Go API and switching to the latest and greatest Eclipse RDF4J. As you probably know, RDF4J is the new name of Sesame which already was an RDF database of choice for RDFBeans development. However, in the previous versions it was accessed via RDF2Go abstraction layer and it appears that this approach creates more problems than it solves.

Now, the framework addresses directly to the RDF4J Repository API for RDF storage functions.

Also, the project infrastructure was cardinally updated:

RDFBeans is an object-RDF mapping and persistence framework. It provides ORM-like databinding functionality to facilitate Linked Data and Semantic Web development in Java by representing domain object models as RDF resources. For detailed information, please refer to:

OnePlus One

No, I didn’t have an invite and got mine from AliExpress: 64GB version in December 2014 cost me $430, that meant $80 over the official price tag. Even with that, I think it was a very good deal.

The phone is being heavily used for a couple of months now and I think I can add my voice to praises the phone received in the media (1, 2, 3, 4 and 5).

My photos on Flickr

I own a free Flickr account since 2006 using it primarily for reposting selected pictures from my self-hosted photo gallery. Now, after major redesign, Flickr offers a free terabyte for everyone and  lots of other nice features, so I decided to migrate all my gallery content to this service:

The old gallery at will be kept in place for archive purposes. I don’t think that any new photos will be posted there.


That morning I was on the balcony checking some antenna cable. Suddenly, a flare of a very bright star on the south-east attracted my attention. The star moved from east to west and quickly grew in size. In few seconds, it had transformed to a fireball similar to the sun in size and brightness. That was a dim dawn twilight but for a couple of seconds everything had brightened like under the midday sunshine.

In another few seconds, the fireball shrank and went out somewhere on the south-west leaving a thick cloudy trace illuminated by the rising sun. Still under the impression of this thrilling show, I rushed downstairs to grab the camera and back to make this shot:

Meteor trace

After the shutter had been released, I heard the sound of a distant explosion and felt the vibration like of a slight earthquake.

The name Zyuratkul refers to the mountain range (1175m in its highest point) and the alpine lake located in the Southern Urals.

It’s been the second summer holidays we spent traveling to Catalonia (this time, there was a bit of nearby Southern France as well).

Upgraded lens kit

For a while I’ve been happy about my all-in-one setup with Sigma 18-250 mega-zoom. But after a year of shooting with that lens, I began to look at a better equipment in terms of optical quality but still not sacrificing universality as possible.

Choosing an OS

There is April – the time of “to upgrade or not to upgrade” question for every Ubuntu user. For sure, the 12.04 “Precise Pangolin” release is going to be LTS (Long-Term Support) so perhaps, the answer in another time would be simple and obvious. But for me, things are much more complex now.

This article is mostly negative but I am rather confused than angry. Yes, I know that it makes no sense to bitch about open-source software: the only adequate response would always be “come in and make it better” and I am 100% agreed with that point. But the problem is much bigger than the bugs or missed features or even than controversial design decisions: the problem is an attitude which is much more difficult, if even possible to fix.
