A small note on window decorations

If you have updated to the recently released GNOME development version, you may have noticed that some window decorations look slightly different. Of course it is quite normal for the theme to evolve with the rest of GNOME, but in this case the visual changes are actually the result of some bigger changes under the hood which deserve some more explanation. It is well-known that GTK+ gained support for client-side decorations a while ago – after all, most GNOME applications were quick in adopting custom titlebars, which have become one of the most distinguished patterns of GNOME 3 applications. However it is less well-known that client-side decorations may also be used for windows with no custom decorations, namely when using GDK’s wayland backend.

PostgreSQL, the NoSQL Database

One of the most interesting trends in the computer world during the past few years has been the rapid growth of NoSQL databases. The term may be accurate, in that NoSQL databases don't use SQL in order to store and retrieve data, but that's about where the commonalities end. NoSQL databases range from key-value stores to columnar databases to document databases to graph databases.

Seeing the cloud through Ubuntu-colored glasses

In Canonical's sixth annual Ubuntu Server and Cloud Survey, the company found -- no surprise -- that the enterprise is rapidly adopting the cloud. Further, the cloud is moving from "mostly development and testing to more production-grade workloads". What kind of cloud? It's still heavily weighted to private clouds, which has 35 percent of users. The most popular platform for private cloud is OpenStack, which is used by 53 percent of users. At the same time, hybrid clouds are on the rise, at 20 percent, up from 15 percent last year. Indeed, the survey found that hybrid clouds are now almost as popular as public cloud, which is at 23 percent.
