Updated Intel Graphics Stack On Ubuntu 14.04 Has Some Slowdowns

Filed under
Graphics/Benchmarks
Ubuntu

For those curious about the impact of running Intel "Haswell" HD Graphics 4600 on Ubuntu 14.04 LTS and then pulling in the latest Mesa 10.3-devel code followed by the Linux 3.15 kernel, it's not entirely a happy story if you are looking to maximize your Intel Linux graphics performance capabilities.

Having done a clean install of Ubuntu 14.04 LTS this week on a Core i7 4770K system I figured I would do the usual graphics driver performance update of comparing Ubuntu 14.04 out-of-the-box (Linux 3.13 + Mesa 10.1) against pulling in the latest Oibaf PPA packages to have xf86-video-intel 2.99.911 DDX and the Mesa 10.3-devel Git master code (a big leap from Mesa 10.1.0). Lastly, with the updated Intel user-space graphics drivers I then updated kernel-space by moving to the Linux 3.15 kernel via the Ubuntu Mainline Kernel PPA.

NVIDIA On Ubuntu 14.04 Has Some New Advantages Over Windows 8.1

Filed under
Microsoft
Ubuntu

In the past when comparing the Linux and Windows performance with NVIDIA graphics when using their proprietary drivers, the performance has largely been the same. With the very latest drivers on each platform, Ubuntu 14.04 LTS seems to have an advantage over Windows 8.1 in many of the tests. With Ubuntu 14.04 LTS we were using the NVIDIA 337.19 Beta as the latest publicly available driver at the time of testing while for Windows 8.1 Pro x64 the 337.50 driver was their latest equivalent. As usual for ensuring accuracy and being a fair "out of the box" comparison, the stock settings were used for each operating system.

Ubuntu 14.10 Will Target Qt 5.3 Support

Filed under
Ubuntu

With Qt5 updates coming just every six months and Ubuntu 14.10 coming out in October, it's fairly expected that Qt 5.3 will be part of Ubuntu 14.10 and it's now been mostly confirmed via the ubuntu-devel list. Qt5 is becoming an increasingly important component to the Ubuntu stack due to its use within Unity 8, etc. Qt 5.3 is also a requirement for the upcoming KDE Plasma Next work. Kubuntu developers though don't intend to ship the next-generation KDE stack in Kubuntu 14.10 by default but to just make it available for those wishing to install it after the fact.

Is Open Source an Open Invitation to Hack Webmail Encryption?

While the open source approach to software development has proven its value over and over again, the idea of opening up the code for security features to anyone with eyeballs still creates anxiety in some circles. Such worries are ill-founded, though. One concern about opening up security code to anyone is that anyone will include the NSA, which has a habit of discovering vulnerabilities and sitting on them so it can exploit them at a later time. Such discoveries shouldn't be a cause of concern, argued Phil Zimmermann, creator of PGP, the encryption scheme Yahoo and Google will be using for their webmail. Read more
