A Look at Redcore Linux: Gentoo based Linux Distribution

tuxmachines.org - Pet, 08/23/2019 - 17:37

Many people in the technology world have heard, at least in passing, of the Linux distribution Gentoo. Gentoo is one of the most famous distributions to the point of becoming a joke; with it’s complexity and depth, installing Gentoo has been a daunting task for many.

Redcore is one of the latest distributions to attempt to bring the power of Gentoo to the everyday user.

I previously wrote an article in 2017 about Sabayon Linux, another popular Gentoo based system; but Redcore Linux holds its own and pulls its own weight.

6 Best Log Management Tools For Linux in 2019

tuxmachines.org - Pet, 08/23/2019 - 17:20

Before we can talk about log management, let’s define what a log is. Simply defined, a log is the automatically-produced and time-stamped documentation of an event relevant to a particular system. In other words, whenever an event takes place on a system, a log is generated. Systems and devices will generate logs for different types of events and many systems give administrators some degree of control over which event generates a log and which doesn’t.

As for log management, It is simply referring to the processes and policies used to administer and facilitate the generation, transmission, analysis, storage, archiving and eventual disposal of large volumes of log data. Although not clearly stated, log management implies a centralized system where logs from multiple sources are collected. Log management is not just log collection, though. It is the management part which is the most important. And log management systems often have multiple functionalities, collecting logs being just one of them.

Once logs are received by the log management system, they need to be standardized into a common format as different systems format logs differently and include different data. Some start a log with the date and time, some start it with an event number. Some only include an event ID while others include a full-text description of the event. One of the purposes of log management systems is to ensure that all collected log entries are stored in a uniform format. This will event correlation and eventual searching much easier down the line.

Even correlation and searching are two additional major functions of several log management systems. The best of them feature a powerful search engine that allows administrators to zero-in on precisely what they need. Correlation functions will automatically group related events, even if they are from different sources. How—and how successfully—different log management system accomplish that is a major differentiating factor.

  • Valve's Proton To Begin Shipping VKD3D For Direct3D 12 Over Vulkan

    While VKD3D continues to be under heavy development, Valve already appears pleased with it enough that it's now being built as part of their Wine-based Proton software for powering Steam Play on Linux.

    VKD3D is the official Wine project being worked on for accelerating Direct3D 12 over Vulkan. This has been Wine's only pursued D3D12 approach with Direct3D 12 not mapping nicely over OpenGL and thus not fitting well into their existing WineD3D code. VKD3D has been able to run a few games, but at last check not many though that may be different these days with it already being included into Proton.

  • Neverwinter Nights: Enhanced Edition has a new DLC out with Tyrants of the Moonsea

    Looking for your next adventure? Neverwinter Nights: Enhanced Edition just got even bigger with a new "premium module" DLC Tyrants of the Moonsea now available.

    For this new expansion, Beamdog teamed up with Ossian Studios. For those unfamiliar, Ossian Studios was formed in 2003 to work on new role-playing games with previous releases including Darkness over Daggerford and Mysteries of Westgate.

    Tyrants of the Moonsea is based on a previously cancelled expansion from Luke Scull, with the Enhanced Edition release boasting "70% more story and gameplay, as well as a large amount of new art and audio content".

  • Space colony building sim Space Haven has a third Alpha release out now

    Space Haven from Bugbyte Ltd continues being shaped into something special, with a third Alpha version now available for this unique colony building sim.

    The latest update overhauls a bunch of the resources in the game, along with adding in 7 new resource production facilities. They said the purpose of this, is to give them a better foundation to build on and give the game some more depth over time.

    While the main focus of this release was on the resources, one other major addition made it in. Players have been asking for a more sandbox-like mode, so they added the ability to create a scenario giving you tons of resources and a crew of 8. This way, you can focus more on building up your fleet of ships right away. Also a good place to test out some ship designs.

  • Looks like the Smach Z handheld gaming unit is getting an upgrade

    The Smach Z team attended this year's Gamescom and is appears they're not done tweaking this gaming handheld.

    While all their current units available for pre-order house the AMD Ryzen V1605B and Radeon Vega 8 Graphics, they've taken it a step further to show off a more powerful Smach Z with the AMD Ryzen V1807B with Radeon Vega 11 Graphics. Not just that, it seems the max storage has been boosted up to 480GB and RAM up to 32GB. Overall, it seems like a pretty nice upgrade.

  • Some more thoughts on Ion Fury, the FPS from Voidpoint and 3D Realms

    Ion Fury (previously Ion Maiden) is true example of how you really don’t need to push graphics ever closer to realism to achieve something ridiculously good.

    Developed by Voidpoint and 3D Realms, using the Build game engine which powered some other classics like Duke Nukem 3D, Blood and Shadow Warrior it released recently with same-day Linux support showing others how it’s done. While it’s retro in many ways, there is of course a vast amount of modern touches like improved physics and map interactions, auto-saves, being able to actually do a headshot, higher resolution support and so on.

    Here’s the thing, I grew up with games like Duke and I’ve seen gaming progress from the Amiga to where we are now. There came a point, where I grew massively tired of retro-inspired flashbacks and in some ways I am still tired of it. However, Ion Fury is a very different sort of brew. The best thing about Ion Fury is that it might seem like other classics but it has a different and refreshing feel to it.

  • 7 Excellent R Natural Language Processing Tools

    Natural language processing (NLP) is a set of techniques for using computers to detect in human language the kinds of things that humans detect automatically.

    NLP is an exciting field of computer science, artificial intelligence, and computational linguistics concerned with the interactions between computers and human (natural) languages. It includes word and sentence tokenization, text classification and sentiment analysis, spelling correction, information extraction, parsing, meaning extraction, and question answering.

    In our formative years, we master the basics of spoken and written language. However, the vast majority of us do not progress past some basic processing rules when we learn how to handle text in our applications. Yet unstructured software comprises the majority of the data we see. NLP is the technology for dealing with our all-pervasive product: human language, as it appears in social media, emails, web pages, tweets, product descriptions, newspaper stories, and scientific articles, in thousands of languages and variants.

  • A muggle's guide to AWK arrays: 3

    Part 2 in this series looked at the 2-file command structure, where the first part of an AWK command created an array based on the first file, and the second part of the command used the array to filter a second file.

    Another way to think about this command structure is that an AWK array is like a lookup table, held in memory. You can use that lookup table for different kinds of data operations on another file. In this post I'll demonstrate reformatting and table joining.

The Linux kernel: Top 5 innovations

tuxmachines.org - Pet, 08/23/2019 - 09:04

The word innovation gets bandied about in the tech industry almost as much as revolution, so it can be difficult to differentiate hyperbole from something that’s actually exciting. The Linux kernel has been called innovative, but then again it’s also been called the biggest hack in modern computing, a monolith in a micro world.

Setting aside marketing and modeling, Linux is arguably the most popular kernel of the open source world, and it’s introduced some real game-changers over its nearly 30-year life span.

Removing Qt 4 from Ubuntu before the 20.04 release

tuxmachines.org - Pet, 08/23/2019 - 08:33

I would like to completely remove Qt 4 from the Ubuntu archive before
the 20.04 release. This includes all of KDE 4 and dependencies.

The Debian Qt/KDE Team (which I am a part of) is raising the status of
the Qt 4 removal bugs to RC[1], and since the Qt 6 work is starting
upstream in the dev branch in the coming months, now is the time for Qt
4 to go.

My timeline for this is to change all of the bugs filed to ask people to
port[2] to removal bugs, and go over the list of Qt 4 reverse
dependencies one last time, so the removal can be done at the beginning
of the 20.04 cycle before the archive opens. This would make 19.10 the
last release with Qt 4.

The lifecycle of Linux kernel testing

tuxmachines.org - Pet, 08/23/2019 - 08:30

In Continuous integration testing for the Linux kernel, I wrote about the Continuous Kernel Integration (CKI) project and its mission to change how kernel developers and maintainers work. This article is a deep dive into some of the more technical aspects of the project and how all the pieces fit together.

Every exciting feature, improvement, and bug in the kernel starts with a change proposed by a developer. These changes appear on myriad mailing lists for different kernel repositories. Some repositories focus on certain subsystems in the kernel, such as storage or networking, while others focus on broad aspects of the kernel. The CKI project springs into action when developers propose a change, or patchset, to the kernel or when a maintainer makes changes in the repository itself.
