New camera

I finally joined the DSLR camp with Canon EOS 600D aka Rebel T3i.

Why Canon?

Well, I’d been a long-time user of PowerShot series and never had long thoughts about my next compact camera: so was with picking a SLR. I felt like improving my shooting experience but not to change it radically. I expected a comfortable learning curve and that the basic UI things were common among all Canon line-ups that would make my transition smoother.

Home IT: Media

One of the important tasks of our home server setup is about media. The server hosts our large and old collections of DVD rips, music and photos that lived on our desktop boxes before. The collections are accessible across the home network with Samba/NFS shares and it works great for devices which can understand it: I mean the computers.

The story would end here if we didn’t want to access the media collections also from TV. This brought me to learn about DLNA technology and to get a DLNA-compliant media player, as well as to install and configure special media server software.

Home IT: Backup

I have to say I am quite serious about losing any bit of my data. It was a time when I backed up everything, including the web-browser history: actually I have dropped this practice only when I realized that every of my tar.gz files overgrew the standard DVD size and that a half of the data I stored didn’t worth it at all.

There is however, a lot of important stuff I’m backing up regularly: projects, documents, Basket notes, emails and so on. A long ago, I have developed a custom automated backup procedure that has been greatly improved with the help of a dedicated server in my home network. The solution is simple, based on standard Linux tools and works perfectly for me.

RDFBeans 2.0

The second edition of RDFBeans Java-to-RDF databinding framework is finally out. In 2.0 version the library underwent major refactoring to clean and enhance the API and provide new databinding techniques.

RDFBeans is an open-source object-RDF databinding and persistence library for the Semantic Web development with Java language. It provides a framework for mapping an object-oriented domain model to RDF resource descriptions.

Home IT

A dedicated server machine is what I definitely needed for my home IT infrastructure which has grown with years. Two desktops, a laptop and a home theatre system: they all needed to be connected to each other and to Internet. For long, it was my desktop box playing a role of the server in the home LAN, and it caused a lot of annoyances, of course.

The last year, an opportunity to bring myself to do it right is appeared, thanks to two things: First, I got new Core-i7 box as my  developer workstation, so my old good Pentium-4 came out of work. Second, a large roll door closet has been built in the hallway where I reserved a room for the server stuff.

Nepomuk-KDE with the Sesame backend
