  • What’s New in Wayland and Weston 1.12?
    The Wayland core protocol documentation has received numerous refinements to improve its clarity and consistency. Along with this, many blank areas of the protocol documentation have been fleshed out. A new wl_display_add_protocol logger API provides a new, interactive way to debug requests; along with this are new APIs for examining clients and their resources. This is analogous to using WAYLAND_DEBUG=1, but more powerful since it allows run time review of log data such as through a UI view. There have been improvements to how the protocol XML scanner handles version identification in protocol headers. This enables better detection and fallback handling when compositors and clients support differt versions of their protocols.

Leftovers: Ubuntu

  • Ubuntu Phone, Sep 2016 - Vorsprung durch Touch
    The Ubuntu Phone is getting better, and with every new iteration of the OTA, my little BQ Aquaris E4.5 is gaining more speed and functionality. Like in the air force, with an avionics upgrade, which transforms ancient wings into a powerful and modern bird of prey. Only the pace of advancement is lagging behind the market. See what Android and iOS can do, even Windows Phone, and you realize how late and insufficiently meaningful the Ubuntu Phone really is. This has to change, massively. This latest round does bring some fine goods to the table - more speed and stability, better icons, more overall visual polish, incremental improvements in the applications and the scopes. But that's not enough to win the heart of the average user. A more radical, app-centric effort is required. More focus on delivering the mobile experience, be it as it may. Ubuntu cannot revolutionalize that which is already considered the past. It can only join the club and enjoy the benefits of a well-established reality. And that is a kickass app stack that makes the touch device worth using in the first place. Still, it's not all gloomy. E4.5 is a better product now than it was a year ago, fact. Ubuntu Phone is a better operating system than it was even this spring, fact. So maybe one day we will see Ubuntu become an important if not dominant player in the phone and tablet space. It sure is heading in the right direction, my only fear is the availability of resources to pull off this massive rehaul that is needed to make it stand up to the old and proven giants. And that's it really. If you're keen on Linux (not Android) making it in the mobile world, do not forget to check my Ubuntu tablet review! Especially the convergence piece. On that merry note, you do remember that I'm running a wicked contest this year, too? He/she who reads my books might get a chance to win an M10 tablet. Indeed. Off you go, dear readers. Whereas I will now run the same set of tests we did here on the Aquaris tablet, and see how it likes the OTA-12 upgrade. The end.
