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.

Linux Performance Analysis: New Tools and Old Secrets

Filed under
Graphics/Benchmarks
Linux

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.

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.

Open source key to preserving human history, argues Vatican

Ammenti explained that, in order for the manuscripts to be readable, the Vatican Library opted for open source tools that do not require proprietary platforms, such as Microsoft Office, to be read. "We save it as a picture as it's longer life than a file. You don't rely on PowerPoint or Word. In 50 years they can still just look at it," he said. Read more

Open Source Router Connects US, Australia

The ONOS Project and partners said Wednesday they have demonstrated the real-world practicality of using a router with open source software to connect networks in Australia and the US. The test validates the vision of SDN, open source for carriers, as well as ON.Lab's ONOS network operating system, according to one of its coordinators. "SDN is about disaggregation of closed, proprietary boxes and separating of forwarding planes, control planes and applications," says Guru Parulkar, executive director and board member of ON.Lab , which coordinates ONOS development. The communications test between Australia and the US achieved just that, he says. (See ON.Lab Aims to Make White Boxes Carrier-Grade , ON.Lab Intros Open Source SDN OS and SK Telecom Bets on SDN for Wireless.) Read more
