Reddit: TMUX - The most magical utility in Linux.

Tuesday 25th of October 2016 03:30:15 AM

Of all the various Linux programs, TMUX is one gem of a utility that is a must-have for all Linux users, and especially for developers. Its fairly common for us to have multiple terminals open on the desktop, for example, one for the php web server, another for python interpreter, another for bash, etc. TMUX helps by combining all these terminals into one (similar to how firefox combines multiple browsers into each tab!).

It creates a small console based green toolbar on the bottom and you can navigate those using simple key combinations (like Ctrl+B+n). Try this out once, and you'll never regret!

  • 4 Useful Cinnamon Desktop Applets

    The Cinnamon desktop environment is incredibly popular, and for good reason. Out of the box it offers a clean, fast and well configured desktop experience.

    But that doesn’t mean that you can’t make it a little better with a few nifty extras.

    And that’s where Cinnamon Applets come in. Like Unity’s Indicator Applets and GNOME Extensions, Cinnamon Applets let you add additional functionality to your desktop quickly and easily.

  • GNOME Core Apps Hackfest

    The hackfest is aimed to raise the standard of the overall core experience in GNOME, this includes the core apps like Documents, Files, Music, Photos and Videos, etc. In particular, we want to identify missing features and sore points that needs to be addressed and the interaction between apps and the desktop.

    Making the core apps push beyond the limits of the framework and making them excellent will not only be helpful for the GNOME desktop experience, but also for 3rd party apps, where we will implement what they are missing and also serve as an example of what an app could be.

  • Netflix on Firefox for Linux

    If you're a Firefox user and you're a little fed up with going to Google Chrome every time in order to watch Netflix on your Linux machine, the good news is since Firefox 49 landed, HTML5 DRM (through the Google Widevine CDM (Content Decryption Manager) plugin) is now supported. Services that use DRM for HTML5 media should now just work, such as Amazon Prime Video. Unfortunately, the Netflix crew haven't 'flicked a switch' yet behind the scenes for Firefox on Linux, meaning if you run Netflix in the Mozilla browser at the moment, you'll likely just come across the old Silverlight error page. But there is a workaround.

    For some reason, Netflix still expects Silverlight when it detects the user is running Firefox, despite the fact that the latest Firefox builds for Linux now support the HTML5 DRM plugin.

  • How open access content helps fuel growth in Indian-language Wikipedias

    Mobile Internet connectivity is growing rapidly in rural India, and because most Internet users are more comfortable in their native languages, websites producing content in Indian languages are going to drive this growth. In a country like India in which only a handful of journals are available in Indian languages, open access to research and educational resources is hugely important for populating content for the various Indian language Wikipedias.

  • Where to find the world's best programmers

    One source of data about programmers' skills is HackerRank, a company that poses programming challenges to a community of more than a million coders and also offers recruitment services to businesses. Using information about how successful coders from different countries are at solving problems across a wide range of domains (such as "algorithms" or "data structures" or specific languages such as C++ or Java), HackerRank's data suggests that, overall, the best developers come from China, followed closely by Russia. Alarmingly, and perhaps unexpectedly, the United States comes in at 28th place.

  • AtScale Delivers Findings on BI-Plus-Hadoop

    Business intelligence is the dominant use-case for IT organizations implementing Hadoop, according to a report from the folks at AtScale. The benchmark study also shows which tools in the Haddop ecosystem are best for particular types of BI queries.

    As we've reported before, tools that demystify and function as useful front-ends and connectors for the open source Hadoop project are much in demand. AtScale, billed as “the first company to allow business users to do business intelligence on Hadoop,” focused its study on the strengths and weaknesses of the industry’s most popular analytical engines for Hadoop – Impala, SparkSQL, Hive and Presto.

  • Study Says OpenStack at Scale Can Produce Surprising Savings

    Revenues from OpenStack-based businesses are poised to grow by 35 percent a year to more than $5 billion by 2020, according to analysts at 451 Research. In its latest Cloud Price Index, 451 Research analyzes the costs associated with using various cloud options to determine when it becomes better value to use a self-managed private cloud instead of public or managed cloud services.

    The idea is to createa complex pricing model that takes into consideration the major factors impacting total cost of ownership (TCO), including salaries and workload requirements.The 451 study found that because of the prevalence of suitably qualified administrators, commercial private cloud offerings such as VMware and Microsoft currently offer a lower TCO when labor efficiency is below 400 virtual machines managed per engineer. But where labor efficiency is greater than this, OpenStack becomes more financially attractive. In fact, past this tipping point, all private cloud options are cheaper than both public cloud and managed private cloud options.

  • How OpenStack mentoring breaks down cultural barriers

  • Intrinsic Is A Promising, Open-Source, Cross-Platform Vulkan Game Engine

    Ever hear of the Intrinsic game engine? Neither have we, until The Khronos Group mentioned it this morning as a new game engine focused on Vulkan support that was open-sourced last week.

    Intrinsic is an open-source cross-platform graphics and game engine that's designed around Vulkan. Intrinsic is still in the early stages of development but the visuals from it so far appear quite good. The game engine is actually GPLv3 licensed but the developer is also making it available for proprietary purposes through private means.

And today, we're able to test drive the second RC build, which introduces even more bug fixes and improvements.

  • LLGL Aims To Be Abstraction Layer For OpenGL, Direct3D 11/12 & Vulkan

    One of my "hobbies" when news is light and there isn't any fun/new/exciting hardware keeping me busy on a given weekend is checking out the various Vulkan projects on GitHub. It's been great seeing all of the independent graphics renderers/engines being tried by different individuals, tons of different Vulkan samples, and a lot of other innovative projects around Vulkan, many of which I've written about in the past few months on Phoronix. One of the projects I see being regularly updated when checking on weekends and haven't written about yet is LLGL, the Low-Level Graphics Library.

Games for GNU/Linux

  • Why GNU/Linux ports can be less performant, a more in-depth answer
    When it comes to data handling, or rather data manipulation, different APIs can perform it in different ways. In one, you might simply be able to modify some memory and all is ok. In another, you might have to point to a copy and say "use that when you can instead and free the original then". This is not a one way is better than the other discussion - it's important only that they require different methods of handling it. Actually, OpenGL can have a lot of different methods, and knowing the "best" way for a particular scenario takes some experience to get right. When dealing with porting a game across though, there may not be a lot of options: the engine does things a certain way, so that way has to be faked if there's no exact translation. Guess what? That can affect OpenGL state, and require re-validation of an entire rendering pipeline, stalling command submission to the GPU, a.k.a less performance than the original game. It's again not really feasible to rip apart an entire game engine and redesign it just for that: take the performance hit and carry on. Note that some decisions are based around _porting_ a game. If one could design from the ground up with OpenGL, then OpenGL would likely give better performance...but it might also be more difficult to develop and test for. So there's a bit of a trade-off there, and most developers are probably going to be concerned with getting it running on Windows first, GNU/Linux second. This includes engine developers.
  • Why Linux games often perform worse than on Windows
    Drivers on Windows are tweaked rather often for specific games. You often see a "Game Ready" (or whatever term they use now) driver from Nvidia and AMD where they often state "increased performance in x game by x%". This happens for most major game releases on Windows. Nvidia and AMD have teams of people to specifically tweak the drivers for games on Windows. Looking at Nvidia specifically, in the last three months they have released six new drivers to improve performance in specific games.
  • Thoughts on 'Stellaris' with the 'Leviathans Story Pack' and latest patch, a better game that still needs work
  • Linux community has been sending their love to Feral Interactive & Aspyr Media
    This is awesome to see, people in the community have sent both Feral Interactive & Aspyr Media some little care packages full of treats. Since Aspyr Media have yet to bring us the new Civilization game, it looks like Linux users have been guilt-tripping the porters into speeding up, or just sending them into a sugar coma.
  • Feral Interactive's Linux ports may come with Vulkan sooner than we thought
  • Using Nvidia's NVENC with OBS Studio makes Linux game recording really great
    I had been meaning to try out Nvidia's NVENC for a while, but I never really bothered as I didn't think it would make such a drastic difference in recording gaming videos, but wow does it ever! I was trying to record a game recently and all other methods I tried made the game performance utterly dive, making it impossible to record it. So I asked for advice and eventually came to this way.

Leftovers: Software

  • DocKnot 1.00
    I'm a bit of a perfectionist about package documentation, and I'm also a huge fan of consistency. As I've slowly accumulated more open source software packages (alas, fewer new ones these days since I have less day-job time to work on them), I've developed a standard format for package documentation files, particularly the README in the package and the web pages I publish. I've iterated on these, tweaking them and messing with them, trying to incorporate all my accumulated wisdom about what information people need.
  • Shotwell moving along
    A new feature that was included is a contrast slider in the enhancement tool, moving on with integrating patches hanging around on Bugzilla for quite some time.
  • GObject and SVG
    GSVG is a project to provide a GObject API, using Vala. It has almost all, with some complementary, interfaces from W3C SVG 1.1 specification. GSVG is LGPL library. It will use GXml as XML engine. SVG 1.1 DOM interfaces relays on W3C DOM, then using GXml is a natural choice. SVG is XML and its DOM interfaces, requires to use Object’s properties and be able to add child DOM Elements; then, we need a new set of classes.
