Chapman: Unlocking my Lenovo laptop

5 hours 19 min ago
In a lengthy blog series (part 1, part 2, and part 3), Matthew Chapman described the process of getting a non-Lenovo battery to charge in his Thinkpad laptop. He reverse-engineered the authorization that real batteries do and changed the code in the embedded controller (EC) on the laptop to allow other batteries to charge. "I look in BIOS to see where these messages are coming from. Both this message and the original unauthorised battery message are displayed by LenovoVideoInitDxe.efi: don’t ask me why this code is in this module rather than somewhere more relevant (may I suggest LenovoAnnoyingBatteryMessageDxe.efi?), but it might have been convenient to put it in the video initialisation module as the message is displayed when the screen is cleared post-POST [Power-on self-test]." (Thanks to Neil Brown.)

D’Souza: Maru is open source!

5 hours 46 min ago
On the Maru blog, developer Preetam D’Souza has announced that the Maru project is now open source. Maru is a desktop system running on a smartphone, so that adding a display, keyboard, and mouse to a phone allows the user to run their desktop on the phone—and still be able to use the device as a phone. "I’ve gotta say, the open source community never ceases to amaze me. I’ve had emails from people asking if they can help test Maru on other devices on a Sunday. How many normal people do you know that willingly want to give up their Sundays to help test software? I’ve experienced this helpfulness time and time again, whether it was the speakers at open source conferences so willing to share their knowledge, or the folks on forums who were so keen to help out beginners like me. Maru would never have been possible without that spirit of openness."

[$] Winning the copyleft fight

9 hours 54 min ago
Bradley Kuhn started off his 2016 talk by stating a goal that, he hoped, he shared with the audience: a world where more (or most) software is free software. The community has one key strategy toward that goal: copyleft licensing. He was there to talk about whether that strategy is working, and what can be done to make it more effective; the picture he painted was not entirely rosy, but there is hope if software developers are willing to make some changes.

Is the vinyl LP an open music format? (

10 hours 8 min ago
Chris Hermansen looks at an early open music format—vinyl LP records—over at He goes into some of the details of the format and how it is read, as well as a bit about ripping records using Linux. "Ok, so we just figured out that our stylus puts 136 times as much pressure on our records as our car puts on the pavement? That's crazy!!! Why doesn't the stylus completely destroy the record? Those alternate-Earth physicists and engineers are rolling on the floor now, clutching their bellies and gasping for breath... but here is the final straw. Despite the seemingly ridiculous or even impossible nature of the whole ensemble of components, a well-recorded vinyl LP played back with a decent turntable, tonearm, and cartridge sounds wonderful."

[$] A Linux-powered microwave oven

Wednesday 10th of February 2016 07:08:29 PM
Scratching an itch is a recurring theme in presentations at 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 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 (

Thursday 4th of February 2016 10:18:53 PM
Over at, 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 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."
