Btrfs hands on: My first experiments with a new Linux file system

Filed under
Linux

Btrfs is a new file system for Linux, one that is still very much in development. Although I wouldn't exactly describe it as "experimental" any more, it is, as stated in the Wiki at kernel.org, "a fast-moving target".

It has also been said publicly that the basic format and structure of the filesystem should now be stable; it would only be changed in the future if some overriding reason or need is found.

The point of all this should be clear — it is still very early days, and it is not recommended to use btrfs in critical systems of any kind.

I leave it to the reader to decide how critical their systems are; for my own purposes, I will be using btrfs on several systems that I use as testbeds, some of which I carry with me and use for normal work on a daily basis, so it will get a "real" test, but I will not be using it on the primary systems that my partner and I use for home/work/business activities.

Distros For Old Computers

Filed under
Linux

Defining hardware as “older” is tricky. Newer resource hungry software levering on the pace of hardware developments is rendering even relatively newer hardware obsolete. Examples of these relatively recent “older” hardware would be single-core or dual-core AMD Athlons and Intel Pentiums.

How an open-source computer kit for kids based on Raspberry Pi is taking over Kickstarter

Filed under
Linux
Gadgets

When the Raspberry Pi was developed, founder Eben Upton envisioned that the low-cost computer would do its finest work in the classroom, teaching kids about computing. But as more units sold, Raspberry Pi developed a strong, distinctive niche among adult makers, a fruitful group that nonetheless doesn’t really have much in common with a younger age bracket that can be hard to reach.

Android head talks Project Svelte and how Android 4.4 KitKat is the leanest Android version yet

Filed under
Linux

Back during Google IO 2012, Android 4.1 Jelly Bean was officially unveiled unto the world. Major firmware versions always bring their share of new features, it was a little something Google called Project Butter that got us the most excited. Addressing Android less than consistent frame rates, Project Butter looked to finally make the Android UI as silky and smooth as iOS butter.

Ex-Nokia engineers launch a Linux smartphone that runs Android apps

Filed under
Linux

InfoWorld's Simon Phipps has written before about how Nokia and BlackBerry could have been major competition for Apple had they embraced more open ecosystems. It's unlikely Jolla and Sailfish will make much of a dent in a marketplace already ruled by Android, despite Sailfish's Android compatibility. But given how much ex-Nokia talent is bound up in this project, it'll be worth watching just to see how their approach unfolds and whether it'll become its own animal or just another way to run Android.

Linux

Docker is a tool for bundling everything you need to run a particular application into a single “container.” These containers can be moved from computer to computer — be they physical machines or virtual computer servers — in much the same way a standardized shipping container can be loaded onto any ship or train or loading dock.

iBuyPower Launching An AMD-Based Steam Machine

Filed under
Linux

The first iBuyPower Steam Machine is expected to be powered by an AMD processor and is said to have a Radeon R9 270 graphics card. It's nice to see it's not a problematic R9 290 GPU and the R9 270X works well under Linux when using the Catalyst driver. The iBuyPower device will surely be using the binary blob for better OpenGL support and performance with the RadeonSI Gallium3D driver being only half-baked for GCN hardware.

    Amazon has become the latest tech giant that’s giving away some of its most sophisticated technology. Today the company unveiled DSSTNE (pronounced “destiny”), an open source artificial intelligence framework that the company developed to power its product recommendation system. Now any company, researcher, or curious tinkerer can use it for their own AI applications.
  • Genode OS Framework release 16.05

It is the result of countless experiments and the practical experiences made while developing over hundred genuine components during the past ten years.
  • Old projects and the free-software community
    The Community Leadership Summit (CLS) is an annual event for community managers, developer evangelists, people who work on public-facing forums, and those with a general interest in engagement or community development for free-software projects. The 2016 edition was held in Austin, Texas the weekend before OSCON. Several sessions at CLS 2016 dealt with the differences exhibited between old and new free-software projects where community management is concerned. One of those tackled the problem of how to foster community around an older software project, which poses a distinct set of challenges.

  • The open-source generation gap
    OSI General Manager Patrick Masson was one of the session's attendees, and he pushed back on that last point. There is too much "open-washing" these days, he said, but it does not come from the OSI. There is still only one Open Source Definition; the dilution of the term comes from others who use "open" to describe organizations, workflows, processes, and other things unrelated to software licensing. "We have open hardware and open data, but also 'open cola' and 'open beer.' That blurs over an important distinction. Not everything fits." [...] Among the other points raised during the session, attendees noted that it was important that the community distinguish between minting new project contributors and minting new free-software activists, and that it was important for projects to put a check on flamewar-style debates—particularly those that focus on dismissing certain technologies. It is easy for experienced developers to become attached to a language or framework, but there will always be new languages and projects popping up that are the entry points for new coders. Project members deriding language Y because it is not language X may only serve to tell newcomers that they are not welcome.
  • A discussion on combining CDDL and GPL code
    Within the context of an event dedicated to discussing free and open-source software (FOSS) legalities, such as the Free Software Legal & Licensing Workshop (LLW), the topic of conflicting licenses was bound to come up. The decision by Canonical to start shipping the ZFS filesystem with its Ubuntu server distribution back in February led to a discussion at LLW about distributing the kernel combined with ZFS. Discussions at LLW are held under the Chatham House Rule, which means that names and affiliations of participants are only available for those who have agreed to be identified. This year's LLW was held in Barcelona, April 13-15.

  • Hackaday Prize Entry: An Interface For The Headless Linux System
    Connecting a headless Raspberry Pi to a wireless network can be quite a paradoxical situation. To connect it to the network, you need to open an SSH connection to configure the wireless port. But to do so, you need a network connection in the first place. Of course, you can still get command-line access using a USB-to-UART adapter or the Pi’s ethernet port – if present – but [Arsenijs] worked out a much more convenient solution for his Hackaday Prize entry: The pyLCI Linux Control Interface.
  • RepRap, Open Source and 3DPrinting
    The RepRap project started in 2005 by Adrian Bowyer – “Mister RepRap”, when the patent about this technology expired. 3DPrintings isn’t a new technology, history dates that the first model of stereolithography printing emerged in 1984. The main idea around RepRap projects is to produce 3DPrinters that can auto-replicate most of the parts itself. And in 2006, the RepRap 0.2 successfully printed the first part of itself and in 2008, the first 3d model was printed by an end-user. Currently, the printer more replicated and customized of the 67 printers that are listed on RepRap website, is the Prusa Mendel, the model created by Josef Průša, that was disponibility to the public in 2011 and had a lot of development since.

  • LeMaker Guitar review
    Anyone who has worked with the Compute Module will find the LeMaker Guitar immediately familiar. The system-on-chip processor, an Actions S500, sits alongside 1GB of memory, a combined audio and power management unit, and 8GB of NAND flash storage on an over-sized small-outline DIMM (SODIMM) form factor circuit board. This board then connects to a baseboard, supplied with the Guitar, which provides more accessible connectivity than the SODIMM’s 204 electrical contacts.
