Those with a bit of humor will love the demo NVIDIA recently used for showing off their Nouveau-based open-source graphics driver stack on the Tegra K1 SoC.

Last month at FOSDEM was a presentation on the Nouveau Tegra K1 driver stack by Alexandre Courbot of NVIDIA. In there NVIDIA talked about their great experience working on this open-source driver and engagement with the Nouveau community, which will continue for future Tegra SoCs. That aforelinked article covered all of the important details of that presentation.

A Look At BCache vs. LVM Cache For HDD+SSD Linux Systems

Filed under

Linux

For those thinking about potentially running a Linux system with a combination of SSD and HDD so that the solid-state drive would be able to act as a performance cache for commonly used data, BCache and LVM-cache/dmcache are two of the commonly used solutions.

For those interested in LVM Cache or BCache, Fedora developer Vratislav Podzimek has written a lengthy blog post comparing these two hybrid caching solutions for Linux -- including setup procedures and steps for Fedora users.

A look at Android 5.1: speed, security, tweaks

Filed under
Android
Graphics/Benchmarks

5.1 also makes many small interface changes, documented in the gallery above. Notification and volume controls have seen improvement, and the OS has been tweaked and polished all over.

In addition, 5.1 brings built-in support for dual SIMs (previously something OEMs had to add) and HD Voice support.

Android 5.1 is one of the smaller minor version Android updates, down there with versions 4.2 and 4.3. But it brings a few nice changes and thankfully seems to solve many of the Nexus 6 performance problems.

Raspberry Pi 2: Raspbian (ARMv6) v Linaro (ARMv7) - Benchmarking

Filed under
Graphics/Benchmarks
Linux

The Raspberry Pi Foundation make it pretty clear that Raspbian is the recommended operating system for the Raspberry Pi series of computers. Most of the Foundation's documentation and support directs users to Raspbian. The downloads section of their website does list other operating system images. But there are many more images available, and one really piqued my curiosity; a Ubuntu 14.10 / Linaro 15.01 "developer" image. Unlike Raspbian, this image is compiled for ARMv7/armhf.
