[$] A Linux-powered microwave oven

Wednesday 10th of February 2016 07:08:29 PM
Scratching an itch is a recurring theme in presentations at linux.conf.au. As the open-hardware movement gains strength, more and more of these itches relate to the physical world, not just the digital. David Tulloh used his presentation [WebM] on the “Linux Driven Microwave” to discuss how annoying microwave ovens can be and to describe his project to build something less irritating.

SourceForge dumps DevShare

Wednesday 10th of February 2016 03:14:07 PM
The SourceForge hosting site has announced that it has a new owner (BIZX, LLC, along with Slashdot) and that it will be getting rid of the controversial DevShare program, which was covered here in 2013. "As of last week, the DevShare program was completely eliminated. The DevShare program delivered installer bundles as part of the download for participating projects. We want to restore our reputation as a trusted home for open source software, and this was a clear first step towards that. We’re more interested in doing the right thing than making extra short-term profit."

The US government's "Cybersecurity National Action Plan"

Wednesday 10th of February 2016 12:12:31 AM
The Obama administration has put out a plan for how it would like to make the net a safer place. There are a lot of topics covered here; toward the end it also mentions that "the Government will work with organizations such as the Linux Foundation’s Core Infrastructure Initiative to fund and secure commonly used internet 'utilities' such as open-source software, protocols, and standards. Just as our roads and bridges need regular repair and upkeep, so do the technical linkages that allow the information superhighway to flow."

[$] Protecting systems with the TPM

Tuesday 9th of February 2016 09:41:35 PM
"TPM," said Matthew Garrett in his linux.conf.au 2016 talk, stands for "trusted platform module"; it is a tool that is meant to allow a system's owner to decide which software to trust. Some years ago, there was a lot of fear that the TPM would be used, instead, to take that decision away, to allow others to decide which software would be trusted to run on our systems; for that reason, some called "trusted computing" by the rather less complimentary name "treacherous computing." That scenario didn't come about, though, for a number of reasons, both technical and social. But we can still use the TPM for its original purpose; Matthew was there to talk about his work to bring about computing that we can trust.

It’s Been 20 Years Since This Man Declared Cyberspace Independence (Wired)

Monday 8th of February 2016 11:40:04 PM
Wired talks with John Perry Barlow on the 20th anniversary of his Declaration of Independence of Cyberspace. "In the modern era of global NSA surveillance, China’s Great Firewall, and FBI agents trawling the dark Web, it’s easy to write off Barlow’s declaration as early dotcom-era hubris. But on his document’s 20th anniversary, Barlow himself wants to be clear: He stands by his words just as much today as he did when he clicked “send” in 1996."

Kernel prepatch 4.5-rc3

Monday 8th of February 2016 02:37:45 PM
The 4.5-rc3 kernel prepatch is out. "It's slightly bigger than I'd like, but not excessively so (and not unusually so). Most of the patches are pretty small, although the diff is utterly dominated by the (big) removal a couple of staging rdma drivers that just weren't going anywhere. Those removal patches are 90% of the bulk of the diff."

First Ubuntu Touch Tablet Brings Convergence at Last (Linux.com)

Thursday 4th of February 2016 10:18:53 PM
Over at Linux.com, Eric Brown looks at the newly announced Ubuntu Touch tablet. The hardware: "The Aquaris M10 is equipped with a 64-bit, quad-core, Cortex-A53 MediaTek MT8163A system-on-chip clocked to 1.5GHz, along with a high-powered ARM Mali-T720 MP2 GPU. The tablet ships with 2GB of RAM, 16GB flash, and a microSD slot." It is said to have 1920x1200 resolution and an 8 megapixel camera capable of HD recording. The interface will change to take advantage of larger displays and additional input devices (e.g. keyboard, mouse). "It appears that the upcoming Ubuntu 16.04 “Xenial Xerus” LTS release due in April will be the first true convergence release. According to PC World, it will still be optional, however, with a traditional Unity 7 build with X.org available alongside the newly converged Unity 8 with the new Mir display server. The new tablet, and Unity 8, will feature Ubuntu Touch’s Scopes interface, which presents frequently used content and services as an alternative to traditional apps. In addition to automatically changing the interface in response to new screens and input devices, Ubuntu is also providing convergence on the application development level. Developers are already developing single apps that can automatically morph into desktop, phone, and tablet formats."

Catanzaro: On WebKit security updates

Tuesday 2nd of February 2016 08:57:33 PM
Michael Catanzaro describes the sad state of WebKit security on Linux distributions and the challenges of security support for such a complex package in general. "We regularly receive bug reports from users with very old versions of WebKit, who trust their distributors to handle security for them and might not even realize they are running ancient, unsafe versions of WebKit. I strongly recommend using a distribution that releases WebKitGTK+ updates shortly after they’re released upstream. That is currently only Arch and Fedora. (You can also safely use WebKitGTK+ in Debian testing — except during its long freeze periods — and Debian unstable, and maybe also in openSUSE Tumbleweed. Just be aware that the stable releases of these distributions are currently not receiving our security updates.)" Lots of information here, worth a read for anybody interested in the topic.

[$] Whole-house audio with free hardware and software

Monday 1st of February 2016 10:55:22 PM
The Black Forest fire destroyed over 500 Colorado houses in June 2013; one of those belonged to longtime Debian developer Bdale Garbee. As he reported during his talk at the 2016 linux.conf.au Multimedia and Music miniconf, the house has been redesigned and rebuilt and life is generally better now. Part of the rebuilding process included the incorporation of a whole-house audio system; naturally, Bdale took a unique approach to that task. His talk showed what can be done when one starts from scratch — and doesn't mind designing a circuit board along the way.
