Hardware
Reviews

In all respects this is the Samsung quality as the original Gear S strap you are currently using, so you know this product well, but it is currently selling for £40 in the UK, which is about $62USD. This is a good product, but it’s at a premium price and you have to ask yourself, Do I really need it?

Turn on your computer from anywhere with an Arduino Server

Filed under
Hardware
OSS

Unless you live off-the-grid and have abundant free electricity, leaving your rig on while you go away on trips is hardly economic. So if you’re like [Josh Forwood] and you happen to use a remote desktop client all the time while on the road, you might be interested in this little hack he threw together. It’s a remote Power-On-PC from anywhere device.

It’s actually incredibly simple. Just one Arduino. He’s piggybacking off of the excellent Teleduino software by [Nathan] who actually gave him a hand manipulating it for his purpose. The Arduino runs as a low-power server which allows [Josh] to access it via a secure website login. From there, he can send a WOL packet to his various computers to wake them up.

From Gongkai to Open Source

Filed under
Hardware
OSS

Compared to the firmware, the hardware reverse engineering task was fairly straightforward. The documents we could scavenge gave us a notion of the ball-out for the chip, and the naming scheme for the pins was sufficiently descriptive that I could apply common sense and experience to guess the correct method for connecting the chip. For areas that were ambiguous, we had some stripped down phones I could buzz out with a multimeter or stare at under a microscope to determine connectivity; and in the worst case I could also probe a live phone with an oscilloscope just to make sure my understanding was correct.

Open hardware is the physical foundation of the open movement. It is through understanding, designing, manufacturing, commercializing, and adopting open hardware, that we built the basis for a healthy and self-reliant community of open. And the year of 2014 had plenty of activities in the open hardware front.

Fedora 21 Released For POWER & AArch64 Hardware

Red Hat
Hardware

While Fedora 21 was officially released last week, coming out today is the release of Fedora 21 for the PowerPC and ARM AArch64 architectures.

Fedora 21 and its packages are now officially available for IBM POWER servers as the only PowerPC systems being officially supported by the PPC release. Support for Apple's older PowerPC systems is mentioned as a PPC platform that's most likely broken and will not be working out-of-the-box. Fedora for POWER in the 21 release offers an installer for the Fedora Server product, support for 32-bit Power has been dropped in favor of 64-bit, and there's numerous enhancements to Fedora on POWER compared to older releases.

Generic TrustZone Driver Proposed For Linux Kernel

Filed under
Hardware

ARM's security extensions are in the process of being bettered on Linux.

TrustZone is the marketing name for ARM's security extensions. TrustZone exposes two virtual processors with hardware access controls to let the application core switch between the two virtual states to avoid potentially leaking any information from one state/world to the other. TrustZone has been around going back to the ARMv6 days and there's been Linux support but it's largely been platform specific. Now, however, a generic TrustZone driver might finally come to the Linux kernel.

Ubuntu Convergence

  • The Race to Convergence: Or is it a Marathon?
    This article, although it was smart to feature Ubuntu as a forerunner, it foolishly tried to give credit to Microsoft for ‘truly being the first’ to do convergence. First, did they? I had no idea. Nor do I care. Nor does anyone else I roll with. If the name has ‘Microsoft’ in it, we flee for the hills. Why? Because it’s compromised out of the box. It is dangerous.
  • Have We Converged Yet?
    Convergence is not about a unified computing experience across all your devices. Although that's an important goal, convergence is more about that point in time where your philosophy that technology should respect people converges with that of a group or company that believes the same.
  • Ubuntu.com Gets a New Look for the Tablet Section, Rest of Website to Follow
    With the new Ubuntu tablet out the door, Canonical also had to upgrade the website to reflect the changes accordingly, so now ubuntu.com has a really nice section dedicated to the BQ Aquaris M10. If we don't take Android into account, we can't really say that there are successful Linux-based tablet out there. It's not clear why that came to pass, but until this Ubuntu-powered tablet landed, there wasn't much competition. To be fair, there is not much competition right now, since Apple and Google pretty much dominate the market, but BQ Aquaris M10 is the only one that can double down as a regular PC.
  • BQ Ubuntu Tablet Has 64-bit CPU and Will Be Able to Run 32-bit ARM Apps
    The BQ Aquaris M10 Ubuntu tablet is powered by a 64-bit ARM processor, so the users have already started to ask around if they will be able to run the 32-bit apps from the phone on the tablet. The short answer is yes. The long answer is that it will take a little bit of work.
  • What the Ubuntu Convergence Means for Businesses, Consumers, OEMs, and Devs
    As you may well be aware, Canonical and BQ unveiled the world's first Ubuntu Tablet, the BQ Aquaris M10 Ubuntu Edition, which also happens to be the first Ubuntu converged device, which users can transform into a full-fledged PC.

Docker Images Are Moving From Ubuntu To Alpine Linux

Docker is reportedly going to be migrating all of their official images from an Ubuntu base to now using Alpine Linux. Alpine Linux is the lightweight distribution built atop musl libc and BusyBox while using a GrSecurity-enhanced Linux kernel. Alpine Linux uses OpenRC as its init system. If you are unfamiliar with this "Small. Simple. Secure." distribution, you can learn more via AlpineLinux.org. The image for Alpine is a mere 5MB.

Meaning of Convergence, Exploit Excludes Linux

The big news yesterday and even into today was the new Ubuntu tablet, which everyone including Canonical touted as "convergence delivered." Well, today Randall Ross scolds news sites for missing the "timely idea" that is convergence. In other news, security researchers have identified a new exploit that specifically avoids Linux. FOSS Force found that Linux users have no interest in anti-virus software and Phoronix reports on Ubuntu performance over the years. Read more
