With Feral Interactive releasing Total War: WARHAMMER for Linux this morning, you are probably curious how well this Linux OpenGL game port will perform with your graphics card prior to spending $60 USD for the game. Up now are my NVIDIA GeForce benchmarks for Total War: WARHAMMER on Ubuntu Linux with nine different graphics cards. In the hours ahead will be the relevant AMD tests with this newest AAA Linux game as soon as I finish up that testing.

Reddit - Tue, 2016-11-22 17:14

Hi, I am very interested in customizing the LibreElec OS for my own personally use obviously, my question is how can I get https://github.com/LibreELEC/LibreELEC.tv into something that I can modify the source code of then build into a bootable .img file? I have programming experience so I can work that side of things out. I just need to know how to start out! Thanks in advance!

Is Init still relevant?

Reddit - Tue, 2016-11-22 17:06

I'm just finishing up my third semester of a computer networking degree and I was planning on taking a few certification tests over the winter break possibly Linux+ and LPIC-2. All of the distributions I've used so far are systemd based but every textbook mentions init. Should I study both init and systemd or just focus on systemd?

  • Finding a Non-Mac Alternative to Microsoft

    A. If you do not care for Windows 10 but want to stick with Microsoft Office, the Mac and the macOS version of Office would probably provide the most familiarity. But if the Mac option is too expensive and you dislike Windows 10 enough to avoid it completely, you might consider switching to an alternative operating system, like a computer running Linux or a Google Chromebook. These systems often have the advantage of being less expensive than standard PC or Mac hardware, but they may require an internet connection to perform many functions.

    Containers as the unit of software

    Hidden behind my hypothosis, which mainly went unsaid, was that containers are becoming the unit of software. By which I mean the software we build or buy will increasingly be distributed as containers and run as containers. The container will carry with it enough metadata for the runtime to determine what resources are required to run it.

    The number of simplying assumption that come from this shared contract should not be underestimated. At least at the host level you're likely to need lots of near-identical hosts, all simply advertising their capabilities to the container scheduler.

  • DatArcs Is Aiming For Dynamically-Tuned, Self-Optimizing Linux Servers

    DatArcs is a new software start-up aiming to provide software to dynamically tune Linux servers for maximum performance and energy efficiency in the data-center. The DatArcs optimizer analyzes the server's workload over time and optimizes the server "several times per minute" to achieve better performance or lower power use.

  • GTK+ 3.89.1 Released As First Development Step Towards GTK4

  • Great Debian meeting in Seville

    Last week we had an interesting Debian meeting in Seville, Spain. This has been the third time (in recent years) the local community meets around Debian.

    We met at about 20:00 at Rompemoldes, a crafts creation space. There we had a very nice dinner while talking about Debian and FLOSS. The dinner was sponsored by the Plan4D assosiation.

  • Zorin OS 12 Is A Linux-Based Alternative For Windows 10

    We understand that it can be difficult to wean yourself off Windows. It's a ubiquitous operating system that most people are used to. But Microsoft's latest operating system Windows 10 has had some persistent privacy concerns. So if you're looking for an alternative but can't bear to give up the familiar user interface (UI), you could try out the Linux-based Zorin OS. The latest release is made to look and feel like Windows 10. Here are the details.

    There have been numerous attempts to replicate the Windows UI on Linux operating systems (does anybody remember Lindows?). In recent years, Zorin OS has become a popular choice for those who want to run Linux but didn’t' want to give up the Windows UI.

Why I love Linux, and strace especially

Reddit - Tue, 2016-11-22 16:01

setup: Oracle 11G on a RHEL7 VM. 1 DB running fine only using 13GB of RAM of the 64 configured on the VM. Trying to startup another database and getting

ORA-27102: out of memory Linux-x86_64 Error: 28: No space left on device

Well this is obviously wrong. Oh and Oracle in its infinite wisdom decided not to log exactly what it is going on. Of course I have enough memory and the DB instance isnt asking for anything more than what the server has. I figured this is just Oracle being obtuse and terse in its error messages since its obviously wrong. We're probably hitting some other 'X' failure condition but its causing this error to come out

The fix: strace on the sqlplus PID with -F and right before the call to write() to write the errors to stdout and I see the following errors -

shmget(0xaddress, 8, 0700) = -1 ENOENT (No such file or directory)

shmget led me down the path to shared memory. I recall Oracle needs specific sysctl changes for shared memory so I increased shmall and boom, it all came up.

Or you know, I could have just googled the ORA error - but what fun would that be :-) http://padmavyuha.blogspot.com/2010/12/configuring-shmmax-and-shmall-for.html

  • How to strengthen your agile heartbeat with powerful retrospectives
  • Python versus R for machine learning and data analysis

    Machine learning and data analysis are two areas where open source has become almost the de facto license for innovative new tools. Both the Python and R languages have developed robust ecosystems of open source tools and libraries that help data scientists of any skill level more easily perform analytical work.

    The distinction between machine learning and data analysis is a bit fluid, but the main idea is that machine learning prioritizes predictive accuracy over model interpretability, while data analysis emphasizes interpretability and statistical inference. Python, being more concerned with predictive accuracy, has developed a positive reputation in machine learning. R, as a language for statistical inference, has made its name in data analysis.

  • Geode: The Latest Apache Big Data Project to Graduate to Top-Level Status

    In recent months, we've steadily taken note of the many projects that the Apache Software Foundation has been elevating to Top-Level Status. The organization incubates more than 350 open source projects and initiatives, and has squarely turned its focus to Big Data and developer-focused tools in recent times. As Apache moves Big Data projects to Top-Level Status, they gain valuable community support. Only days ago, the foundation announced that Apache Kudu had graduated as a Top-Level project.

  • Open Source Week at SitePoint

    At SitePoint, we are proud supporters of Open Source. Regular SitePoint readers may have noticed that! Open is in the DNA of many topics we cover by design; GitHub alone is evidence enough, as it’s pretty much a standard tool for most developers nowadays.

  • Education management with Moodle: The beginning, middle, and today

    Moodle is the de facto standard in open source learning management systems. It is described as "a learning platform designed to provide educators, administrators and learners with a single robust, secure and integrated system to create personalised learning environments." Plus, Moodle is free software, licensed under the GPL.

    Martin Dougiamas, Moodle's founder and lead developer, generously took time from his busy schedule to have a good, long talk with me about why he created it, where it is today, and what's next in open education.

  • Hackathons and bite-sized procurement requests

    Public administrations that want to work with open source communities should organise hackathons and other meetings on software development. They should also publish calls for tender that can be answered by individuals and small businesses. These are some preliminary recommendations from the OSOR workshop at the Paris Open Source Summit last Wednesday.

  • Last batch of ColorHugALS

    I’ve got 9 more ColorHugALS devices in stock and then when they are sold they will be no more for sale. With all the supplier costs going recently up my “sell at cost price” has turned into “make a small loss on each one” which isn’t sustainable. It’s all OpenHardware, both hardware design and the firmware itself so if someone wanted to start building them for sale they would be doing it with my blessing. Of course, I’m happy to continue supporting the existing sold devices into the distant future.

  • Programmers are having a huge discussion about the unethical and illegal things they’ve been asked to do

    Earlier this week, a post written by programmer and teacher Bill Sourour went viral. It's called "Code I’m Still Ashamed Of."

    In it he recounts a horrible story of being a young programmer who landed a job building a website for a pharmaceutical company. The whole post is worth a read, but the upshot is he was duped into helping the company skirt drug advertising laws in order to persuade young women to take a particular drug.

    He later found out the drug was known to worsen depression and at least one young woman committed suicide while taking it. He found out his sister was taking the drug and warned her off it.
