NVIDIA vs. AMD OpenGL & Vulkan Benchmarks With Valve's Dota 2

TuxMachines - Tue, 2016-05-24 22:14

Yesterday marked the public availability of Dota 2 with a Vulkan renderer after Valve had been showing it off for months. This is the second commercial Linux game (after The Talos Principle) to sport a Vulkan renderer and thus we were quite excited to see how this Dota 2 Vulkan DLC is performing for both NVIDIA GeForce and AMD Radeon graphics cards. Here are our initial Dota 2 benchmarks with Vulkan as well as OpenGL for reference when using the latest Linux graphics drivers on Ubuntu.

Empower SMTP With Postscreen: Part 1

I recently read with interest that the powerful mail transfer agent (MTA) that is Postfix has introduced a relatively new addition to its load mitigation and anti-spam arsenal.

Self hosted OpenVPN server in 5min - CoreOS+Docker

Reddit - Tue, 2016-05-24 21:24

If what I'm doing is terribly wrong, then please correct me, but so far this setup worked fine.

Here it goes:

And that is it.

CoreOS it is not designed to run as single node, but who cares, it works great and if I need traditional Linux tools I can use /usr/bin/toolbox which pulls latest stable Fedora image.

If something is not clear, I will try to explain, but I assume people here know what ssh key pair is at least ;)

Why Hyperledger wants to be the ‘Linux of blockchain’

TuxMachines - Tue, 2016-05-24 21:09

Blockchain technology offers many different benefits to enterprise developers — but there’s no cross-industry open standard for how to develop it.

That makes it difficult for vendors and CIO customers to place their bets and begin building it into their technology architecture. Hyperledger, a Linux Foundation project to produce a standard open-source blockchain, wants to solve that problem, and it just got an executive director, Brian Behlendorf, to help it on its way. He founded the Apache Software Foundation, was previously on the board of the Mozilla Foundation and the Electronic Frontier Foundation, and managed tech VC firm Mithril Capital Management.

Google Nexus 6P Review: This is the Android Flagship You’re Looking For

TuxMachines - Tue, 2016-05-24 21:04

This is the flagship Android handset you’re looking for, and best of all it’s reasonably priced. It is unlocked and offers universal wireless carrier support (yes, including Verizon), and it starts at just $500. At that price, you have a choice of silver, graphite, frost, and matte gold finishes and 32 GB of storage. If you want to step up to 64 GB, which I recommend, the price jumps just $50 to $550. (Take that, Apple: A similarly configured iPhone 6S Plus costs $850, or $300 more than the Nexus 6P.) A 128 GB version will set you back an also-reasonable $650. These are fantastic prices for a fantastic flagship device.

And that, folks, is called the sweet spot. The Nexus 6P hits it, and while there are still some platform niceties that make me personally prefer the iPhone, the gap is now smaller than ever. The Nexus 6P is highly recommended.

Rebellin Linux Offers Best of Both Gnome Worlds

TuxMachines - Tue, 2016-05-24 20:52

Both versions generally performed well. The Rebellin distro is impressive considering its small development team.

Rebellin is not without a few glitches, however. One major problem I had with several of my computers testing the distro was with the audio playback in both the GNOME and the Mate editions. It did not play back. I double checked all the settings, even making sure that the mute option was not checked.

Another issue affected just the Mate edition. The touchpad settings are not available, and the Touchpad tab itself is missing. The Synaptics Touchpad Driver is not being loaded in Rebellin Mate, according to Rebellin's developer. He posted a workaround that may temporarily resolve the problem. It is a multistep process that is not very straightforward.

Debian and the Internet of Things

TuxMachines - Tue, 2016-05-24 20:49

Everybody is talking about the Internet of Things. Unfortunately there is no sign of it in Debian yet. Besides some smaller packages like sispmctl, usbrelay or the 1-wire support in digitemp and owfs, there is not much software to control devices over a network.

With the recent upload of alljoyn-core-1504 this might change.

AMDGPU-PRO Beta 2 vs. Mesa 11.3 + Linux 4.6: Very Competitive For Linux Gamers

TuxMachines - Tue, 2016-05-24 20:43

Following last week's AMDGPU-PRO 16.20.3 "Beta 2" driver release of AMD's new hybrid driver stack for Linux that makes use of the AMDGPU open-source kernel DRM driver with the closed-source OpenGL driver derived from Catalyst / Radeon Software, I set out to do a fresh open vs. closed-source driver comparison. For the Radeon R9 285, R9 290, and R9 Fury, I compared the performance of this new AMDGPU-PRO driver against Mesa 11.3-devel Git and Linux 4.6 for the latest open-source driver stack.

Petros Koutoupis' RapidDisk

TuxMachines - Tue, 2016-05-24 20:39

RapidDisk is an open-source and enhanced Linux RAM drive solution led by BDFL Petros Koutoupis (who also writes for Linux Journal) that allows users to create, resize and remove RAM drives dynamically or map those same RAM drives as a cache to slower data volumes. The latest version 4.0 release adds a series of complementary improvements, such as kernel module optimizations, code cleanup/redesign and bug fixes. RapidDisk consists of a collection of kernel modules, an administration utility, high-availability scripts and a RESTful API for third-party integration. By design, RapidDisk volumes are thinly provisioned and will allocate memory only upon usage.

New NVIDIA 361 Linux Driver Released

Phoronix - Tue, 2016-05-24 20:36
While the NVIDIA 367 Linux driver series is where the very latest proprietary driver features from the green team can be found, if you have been sticking to the NVIDIA 361 driver series since it's the current long-lived branch, a new release is now available...

Why Android apps on Chromebooks are a really, really big deal (really!)

TuxMachines - Tue, 2016-05-24 20:30

Put on your thinking caps, my friends, 'cause it's time to get philosophical.

Ponder me this: What constitutes an "Android device"? It's something I've been mulling ever since word broke that the entire Google Play Store of Android apps would be coming to Chrome OS later this year -- and it's a question I'll ask you to keep in mind as we take the time to think through that move and what it could mean for us as consumers.

Samsung is done with Android Wear watches, says Tizen is the future

TuxMachines - Tue, 2016-05-24 20:28

After a chat with Samsung executives, a report from Fast Company says that "no more Samsung Android Wear devices are in development or being planned." Samsung apparently sees its in-house operating system, Tizen, as the wearable future. The report says that Samsung executives are going with Tizen because it's "far more battery-efficient than Android Wear" and "the standard OS on other Samsung products from TVs to refrigerators."
