Reddit: (Subgraph community isn’t that much) help.

Saturday 17th of March 2018 04:18:48 AM

Want to dual boot with sub graph, so I used Rufus and tried to do graphical install until it said unable to install from a media drive, so I downloaded usb Linux installer (forgot the name) and it had the option to boot with grub so I choose it when my computer boot up it said failed and gave me a link to get a download (idk what grub does and should I use it with or without iso). And is there a way to fix my earlier problem? Thanks.

TuxMachines: Programming: Developer Survey, Code That Unmasks, Retaining Newcomers

Saturday 17th of March 2018 04:00:51 AM
  • Developers love trendy new languages but earn more with functional programming

    Developer Q&A site Stack Overflow performs an annual survey to find out more about the programmer community, and the latest set of results has just been published.

  • FYI: AI tools can unmask anonymous coders from their binary executables [Ed: Just a kind reminder that if you are e using Microsoft's tools compile source code, there will be surveillance and telemetry in your compiled code]

    Programmers can be potentially identified from the low-level machine-code instructions in their software executables by AI-powered tools.

    That's according to boffins from Princeton University, Shiftleft, Drexel University, Sophos, and Braunschweig University of Technology, who have described how stylometry can be applied to binary files.

    That's kinda bad news for people who wish to develop software, such as privacy-protecting apps, anonymously, as this technology can be used to potentially unmask them. It's also kinda good news for crimefighters trying to identify malware authors.

  • How to avoid humiliating newcomers: A guide for advanced developers

    Every year in New York City, a few thousand young men come to town, dress up like Santa Claus, and do a pub crawl. One year during this SantaCon event, I was walking on the sidewalk and minding my own business, when I saw an extraordinary scene. There was a man dressed up in a red hat and red jacket, and he was talking to a homeless man who was sitting in a wheelchair. The homeless man asked Santa Claus, "Can you spare some change?" Santa dug into his pocket and brought out a $5 bill. He hesitated, then gave it to the homeless man. The homeless man put the bill in his pocket.

    In an instant, something went wrong. Santa yelled at the homeless man, "I gave you $5. I wanted to give you one dollar, but five is the smallest I had, so you oughtta be grateful. This is your lucky day, man. You should at least say thank you!"


    I still get angry at people on the internet. It happened to me recently, when someone posted a comment on a video I published about Python co-routines. It had taken me months of research and preparation to create this video, and then a newcomer commented, "I want to master python what should I do."

TuxMachines: Software: 5 Online Backup Solutions, Lector, Roundcube

Saturday 17th of March 2018 03:59:26 AM
  • 5 Online Backup Solutions for Ubuntu Linux

    As the digital age progresses, the amount of data we produce each year is snowballing. There was a time when we could fit all of our personal digital data on a few floppy disks, but many of us now have hundreds of gigabytes, or even terabytes, of photos, videos, music, and documents that we need to backup and protect. Backing up our data locally is essential, but any good backup plan should also include off-site backups. “The Cloud” has promised us unlimited, cheap storage where we can save our ever-growing data. Online cloud backups should be a part of your overall backup plan, but it’s crucial that your data is secure, encrypted, and backed up automatically. Here are a few online backup tools that aim to make cloud backups easy for desktop Linux users.

  • This Qt eBook App for Linux is a Real Page Turner

    Lector a new open-source Qt-based ebook app for Linux desktops.

    It supports most common DRM-free ebook files, including EPUB, MOBI, and AZW, as well as comic book files in the CBZ or CBR format.

    In both visuals and in features Lector is something of a page-turner; a desktop ebook reader you can absolutely judge by its cover.

    So join me as I take a closer look at its features.

TuxMachines: Graphics: AMDGPU, Mesa 17.3.7, RADV

Saturday 17th of March 2018 03:27:42 AM
  • Linux 4.17 To Enable AMDGPU DC By Default For All Supported GPUs

    Since the introduction of the AMDGPU DC display code (formerly known as DAL) in Linux 4.15, this modern display stack has just been enabled by default for newer Radeon Vega and Raven Ridge devices. With Linux 4.17 that is changing with AMDGPU DC being enabled by default across the board for supported GPUs.

    Building off the earlier DRM-Next material for Linux 4.17, Alex Deucher minutes ago sent in another round of feature updates for targeting this next kernel cycle. This latest batch has continued code refactoring around PowerPlay, support for fetching the video RAM type from the video BIOS, allowing the TTM memory manager to drop its backing store when not needed, DC bandwidth calculation updates, enabling DC backlight control for pre-DCE11 GPUs, various display code fixes, and other bug fixes.

  • AMDGPU / ATI 18.0.1 X.Org DDX Driver Releases, Fixes Infinite Loop & Crashes

TuxMachines: Server: Containers, Kubernetes, Varnish 6.0, HHVM 3.25.0, 3.24.4, and 3.21.8

Saturday 17th of March 2018 03:25:26 AM
  • Container Isolation Gone Wrong

    One of the main advantages of embracing containers is "lightweight virtualization." Since each container is just a thin layer around the containerized processes, the user gains enormous efficiencies, for example by increasing the container density per host, or by spinning containers up and down at a very fast pace.

    However, as the troubleshooting story in the article will show, this lightweight virtualization comes at the cost of sharing the underlying kernel among all containers, and in some circumstances, this can lead to surprising and undesirable effects that container users typically don't think about.

    This troubleshooting tale is rather involved. I've started from the basics and worked up to the more complex material in the hope that readers at all levels can get value out of it.

  • Introducing Agones: Open-source, multiplayer, dedicated game-server hosting built on Kubernetes

    In the world of distributed systems, hosting and scaling dedicated game servers for online, multiplayer games presents some unique challenges. And while the game development industry has created a myriad of proprietary solutions, Kubernetes has emerged as the de facto open-source, common standard for building complex workloads and distributed systems across multiple clouds and bare metal servers. So today, we’re excited to announce Agones (Greek for "contest" or "gathering"), a new open-source project that uses Kubernetes to host and scale dedicated game servers.

  • HHVM 3.25 Released, Now Defaults To PHP7 Mode

    Facebook developers working on the HHVM Hack/PHP language stack have released version 3.25 of the HipHop Virtual Machine.

    HHVM 3.25's PHP support now defaults to PHP7 rather than the PHP5 mode, which is now in an unsupported state. As expressed previously, Facebook will be focusing more on their Hack language support than PHP7 thanks to all the upstream improvements with PHP 7 especially on the performance front. But the large compatibility with PHP7 will happen to continue at least for the time being. With HHVM 3.25 includes support for PHP7 Throwable/Error/Exception hierarchy, changes to visibility modifiers, and other compatibility work.

  • Your first robot: Sharing with others [5/5]

    This is the fifth (and final) blog post in this series about creating your first robot with ROS and Ubuntu Core. In the previous post we discussed methods of control, did a little math, and wrote the ROS driver for our robot. But it still required several nodes to be running at once, and sharing it with the world involved uploading your source code somewhere and convincing people to install ROS, build your package, and use it. Today we’re going to simplify both of those issues by discussing ROS launch files, and packaging everything we’ve written as a snap that can be installed by your friends with a few keystrokes, even without knowing anything about ROS.

  • Ubuntu Desktop weekly update – 16th March 2018

TuxMachines: Government of Jamaica to Actively Pursue Greater Use of Open Source Software – Wheatley

Saturday 17th of March 2018 02:47:22 AM

Minister of Science, Energy and Technology, Dr. Andrew Wheatley today outlined the Government of Jamaica’s intention to pursue greater use of Open Source Software as part of its thrust to transform ICT within government while at the same time reducing the attendant costs associated with the use of proprietary software.

Guided by recommendations outlined in an Open Source Policy Framework report which was completed in late 2016, Minister Wheatley stated that “It is clear that there are huge benefits to be gained from greater use of open source software by developing countries like Jamaica and we intend to take a more active approach to incorporation of these types of software across government.”

Minister Wheatley in speaking about recurrent enterprise agreements with Microsoft, IBM and other proprietary software vendors said “ for a very long time we have been confined by the strictures and high costs of the license regimes of proprietary software offerings and we will now, in keeping with goals of our Vision 2030 plan, make the move to unleash the innovative capacity of our country by leading the way in the adoption of open source platforms”

Reddit: Question: How to do experiments to better understand Linux system performance?

Saturday 17th of March 2018 12:03:47 AM

There are a lot of metrics (memory usage, system load, disk system usage, interrupts, entropy available, ...) that one can read off a working Linux system.

I am very intrigued by the idea of running experiments to text how a Linux system reacts to different factors. However, I do not have a lot of ideas about what I should be toying with.

I have a home server, and I monitor how running services, SSHing, and high performance computations (e.g. compiling) affects it. What else can I do?

In fact, is there a way I could access a larger system to play with? Are there disciplines that study those things?

Review: ArchMerge 6.4.1

The distribution I have been asked most frequently to cover so far in 2018 is ArchMerge, an Arch-based project which runs the Xfce desktop environment and can be installed using the Calamares system installer. If the description sounds familiar, it should, as this summary could equally well apply to Archman, SwagArch and one edition of the Revenge OS distribution. There are two main features which set ArchMerge apart from its close relatives. First, ArchMerge is available in two flavours. The full featured desktop edition ships with three graphical user interfaces (Xfce, Openbox and i3). A second, minimal flavour is available for people who want to start with a text console and build from the ground up. The other point which helps ArchMerge stand out from the crowd of Arch-based distributions is its documentation. Arch Linux is famous for its detailed wiki, and rightfully so. ArchMerge takes a slightly different approach and, instead of supplying detailed pages for virtually every aspect of the distribution, the project supplies quick overviews and tutorials for common tasks and issues. These overviews are each accompanied by a video which shows the user how to perform the task. The ArchMerge website places a strong emphasis on learning and the tutorial pages guide visitors through how to install the distribution, how to configure the desktop, how to install additional software and how to set up file synchronizing through Dropbox. There is also a section dedicated to fixing common problems, a sort of FAQ for distribution issues. Since there are videos for the topics covered, we are shown where to go and what each step should look like, rather than just being given a written description. Read more
