In this post, you'll find our newly updated collection of many good Linux reference guides and tools online--all available at no cost.

  • Build a better web server – Part 1

    Up your computing power with an upgraded or brand new server that you can build yourself

    While big business and big data may be utilising mainframes more of late, the concept of servers is not going away any time soon. Servers are an integral part of any system, however large your IT infrastructure is. Whether it’s inside the data centre or tucked away in your (well-ventilated!) cupboard at home, there are still a lot of uses for servers in 2015.

    For the office you may want to save a bit of money and create something perfect for your needs that you know exactly how to maintain. For home you may just want to enhance your setup and make the entire network more efficient. For both it’s a great way to separate certain aspects of your network to control it in a more efficient way.

    There are many components of a server that you need to keep in mind, but it boils down to an appropriate hardware selection and a good distro for the task at hand. In this tutorial, we are going to concentrate on file and web servers, two base server systems that can be expanded and modified in multiple ways to best fit the situation you are in.

    As we’re teaching you how to build a better web server, we will first take a quick detour to tell you what you should know if you want to upgrade your current server so that it can compete with the new tech.

  • How many IoT devices do you own?

    The Internet of Things (IoT) is rapidly changing the way we interact with the world around us. A whole host of devices are becoming smarter, more connected, and better able to anticipate our needs. Whether in the form of wearables, home automation, connected cars, or business asset tracking, every day we are seeing a greater level of engagement between the physical world and the digital.

    While this enormous growth in IoT may seem inevitable, like any emerging technology, there are issues which have not yet fully sorted themselves out yet. How can we be sure that all of the devices we own can speak to one another in a language which they all understand, regardless of who manufactured them? How can we be sure we always have access to our data even if we end our relationship with the product's vendor? And how can we know that our data, which by its nature is often quite personal, is always safe and secure?

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.
  • LibreOffice 5.1.6 Office Suite Released for Enterprise Deployments with 68 Fixes
    Today, October 27, 2016, we've been informed by The Document Foundation about the general availability of the sixth maintenance update to the LibreOffice 5.1 open-source and cross-platform office suite. You're reading that right, LibreOffice 5.1 got a new update not the current stable LibreOffice 5.2 branch, as The Document Foundation is known to maintain at least to versions of its popular office suite, one that is very well tested and can be used for enterprise deployments and another one that offers the latest technologies.
