[Video] Hands-On Review of the Samsung Gear S wrist strap – Cobalt Blue

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.

Slackware Live Edition – on its way to 1.0?

Last week the second Beta of the upcoming Slackware 14.2 was released. My goal was to have a new Beta of my liveslak ready by that time, so that I could provide new ISO images to test the Slackware Beta2 on a live medium. Unfortunately, there was an attack of the flu in my team at work and things got a bit busier than usual. There was a plus side to this: some last moment bug fixes which could be applied to my scripts – the result of having more evenings available to test. Therefore the new release is not labeled “0.5.0” but “0.5.1” Read more

Leftovers: KDE

  • Cantor migrating to Phabricator: which tools our contributors must to use
    Projects and software developed by KDE community are going to migrate for a new tool to manage our code, commits, reviews, tasks, and more. This tool is Phabricator and you can visit the instance for KDE projects in this address. Since November 2015 we are migrating Cantor to Phabricator. After our first successful review code some days ago, I decided to write a post about which tools our contributors must to use while the migration process is not finished.
  • Kdenlive's sprint report
    Last week-end, Vincent and me met in Lausanne for a Kdenlive sprint. One of our goal was to merge Gurjot Singh Bhatti's GSoC work on curves for keyframes. This was more work than expected and we spent many hours trying fix the curves and make keyframes behave correctly. Not much time was left for sleep, but we still managed to get outside to make a group (!) picture in the woods above Lausanne.
  • Jekyll 3.x
    I’ve found three different types of transition issues (it is cool to look at these in a project I do not upgrade on a daily basis like Plasma and the rest of the KDE software).
  • kdev-python on Windows: try it!
    I spent the last two or three days playing around with KDE on Windows, with the aim of getting my Python language plugin for KDevelop to run there. In the end, it wasn’t that hard to get this to work — not as hard as I would have expected it to be, anyways.
