At the last USENIX/LISA conference, I gave a talk on new Linux performance tools: my open source perf-tools collection. These use existing kernel frameworks, ftrace and perf_events, which are built in to most Linux kernel distributions by default, including the Linux cloud instances I analyze at Netflix.
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.
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.
X.Org Server 1.17 has made it into Ubuntu 15.04.
While Mir will power the Ubuntu Touch devices, X.Org Server 1.17.1 will be used as the default desktop display server for this next Ubuntu Linux release due out in May. Xorg-server 1.17.1 was uploaded to the Ubuntu Vivid archive yesterday to replace the old 1.16 series.
Nvidia’s $199 STB version of Nvidia Shield runs Android TV on a Tegra X1, and boasts 4K video, 50 optimized games, and game streaming from a “Grid” service.
The 2015 set-top box version of the Nvidia Shield follows two earlier models, including 2013’s original handheld Shield game console, now called the Nvidia Shield Portable, which was based on the Nvidia Tegra 4 system-on-chip. Last year, the chip designer-cum-hardware developer released an Nvidia Shield Tablet built around a more powerful Tegra K1 SoC with Kepler graphics, and featuring new stylus and WiFi Direct gaming controller.
Aaeon’s “EPIC-BDU7″ SBC uses Intel’s 5th Gen Core processors, and offers multiple graphics, GbE, USB, and SATA ports, plus mini-PCIe and PCI-104 expansion.
Aaeon’s EPIC-BDU7 single board computer uses the same old-school EPIC form factor adopted by its Atom-based EPC-CV1 board, but instead loads up with Intel’s brand new 5th Generation Core processors using the 14nm “Broadwell” architecture. Aaeon typically supports Linux on its SBCs, and although no OS support was listed, Linux should run on this board with no problem.
