The What, Why and Wow! Behind the CoreOS Container Linux

Filed under
OS
Linux
Server

Unlike most Linux distributions, CoreOS doesn’t have a package manager. Instead it takes a page from Google’s ChromeOS and automates software updates to ensure better security and reliability of machines and containers running on clusters. Both operating system updates and security patches are regularly pushed to CoreOS Container Linux machines without sysadmin intervention.

You control how often patches are pushed using CoreUpdate, with its web-based interface. This enables you to control when your machines update, and how quickly an update is rolled out across your cluster.

  • Popcorn Linux OS gives processors a common language

    Thanks to a new operating system called Popcorn Linux, the Navy may be able to speed systems development and cut maintenance.

    Developed by engineering researchers at Virginia Tech with support from the Office of Naval Research,  Popcorn Linux can compile different programming languages into a common format.

    The operating system takes generic coding language and translates it into multiple specialized program languages. Then it determines what pieces of the code are needed to perform particular tasks and transfers these instruction “kernels” (the “popcorn” part) to the appropriate function, ONR officials said.

    Chips for video systems might be programmed in one language and those for networking functions in another. These multicore processors improve computing speed, but they also force programmers to design or upgrade applications based on what programs run on which processors. That means complex systems like battlespace awareness and artificial intelligence that require specialized processors must be manually adjusted so components can interact with each other.

  • Are You a Distro Hopper?

    Is distro hopping a dying sport or have I just gotten too old?

    When I first started to use Linux I was the quintessential cliche distro hopper. I swapped and switched flavor of Linux seemingly every other day, certain that at some point I’d find the right fit and stop, content with at whatever combination of distro base and desktop environment I’d hit upon.

  • System76 Continues Working On GNOME Improvements For Future Ubuntu

    System76 continues working on improvements to the GNOME stack as part of their transition in-step to using it over Unity 7, in line with Canonical's decision to switch Ubuntu over to GNOME and abandon their grand Unity 8 ambitions.

  • 2017 Linux Laptop Survey

    It has been a few years since last running any Linux hardware surveys on Phoronix, as overall the ecosystem has rather matured nicely while of course there are still notable improvements to be had in the areas of GPUs and laptops. (Additionally, OpenBenchmarking.org provides a plethora of analytic capabilities when not seeking to collect subjective data / opinions.) But now we are hosting the 2017 Linux Laptop Survey to hopefully further improvements in this area.

Linux owns supercomputing

Filed under

Linux
Server

The US is falling behind in the supercomputer race, but no matter where a supercomputer is running, one thing remains true: It's running Linux.

In the latest Top500 Supercomputer competition, which was revealed in June 2017, 498 out of 500 supercomputers were running Linux. Of the remaining two, both ran Unix.

These were a pair of Chinese IBM POWER computers running AIX near the bottom of the list. These machines came in at 493 and 494. Since the November 2016 Top500, these supercomputers have dropped by over 100 places. At this rate, Linux will score a clean sweep in the next biannual Top500 competition.

When the first Top500 supercomputer list was compiled in June 1993, Linux was barely more than a toy and hadn't adopted Tux as its mascot yet. Starting in 1998, when it first appeared on the Top500, Linux quickly dominated supercomputing.

Manjaro 17.0.1 Gellivara (Che Guevara) - Pretty decent

Filed under
Linux
Reviews

It is time to arch our backs and explore the distroverse some more. That's a horrible pun, I admit, so I'll chase to the cut. Manjaro. It's a nerdy operating system, powered by sacrificial goats, curdled blood, enthusiasm, and heaploads of nerdiness. But then, over the years, it has slowly grown on me, becoming almost usable on a daily basis.

A new version is out, carrying the numerical identifier 17.0.1, and there are several desktop flavors available. In order to test the progress and change in Manjaro, I decided to continue with the Xfce version, and so we can compare to previous editions. Now, the system has a rolling update nature, so I could have just upgraded the installed instance on my Lenovo G50 box, but I decided to go for a full, fresh experience. We commence.

  • How to Install Ubuntu 17.04 with GNOME on Your Chromebook, Alongside Chrome OS

    Last year when I got my Acer Chromebook 11 (C740), I wrote a tutorial to teach you guys how to remove Google Chrome OS and install a GNU/Linux distribution of your choice, but things got boring.

    So after a few months, I reinstalled Chrome OS using a recovery image that Google provides on their website for this sort of things, which I wrote on a USB flash drive and booted from my Chromebook. Recently, I got bored again, and so I decided to install Ubuntu on my Acer Chromebook 11 (C740) using Crouton.

  • Is Chrome OS right for you? A 3-question quiz to find out

    Google's Chrome OS is one of the world's most misunderstood computing platforms. Chromebooks are foundationally different from traditional PCs, after all -- and consequently, there are a lot of misconceptions about how they work and what they can and cannot do.

    Since people are always asking me whether a Chromebook might be right for their needs, I thought I'd put together a quick guide to help any such wonderers figure it out. Whether it's you or someone you know who's curious, the following three questions should help shed some light on what the platform's all about and for whom it makes sense.

  • Lenovo Flex 11 Chromebook Review: Built To Last

    Chromebooks are continuing to make an impact on the market and as a result, more Chromebooks are getting announced and almost on a monthly basis now. One of the most recent Chromebooks to be announced (April 2017) was the Lenovo Flex 11 Chromebook. This is a Chromebook which looks to combine the standard Chrome OS experience with a device that is durable and hardworking. While also looking to ensure the price is competitive by Chromebook standards. In this case, the Lenovo Flex 11 Chromebook is priced at $279.99 for the baseline model.

    It’s almost 9 years I am using GNU/Linux as my default Operating System. The first time I used GNU/Linux was in 2008, when I wanted to crack the password of the computers of my school in order to install and play the games I wanted. So my first contact with GNU/Linux was through OPHCrack. I was absolutely impressed when I could get the password of the computers of my school in less than ten minutes. I was 14 and I think I wanted to be a hacker. Goals changed through time, though.

Development Functional Programming in JavaScript and Learning to Code

  • An introduction to functional programming in JavaScript
    When Brendan Eich created JavaScript in 1995, he intended to do Scheme in the browser. Scheme, being a dialect of Lisp, is a functional programming language. Things changed when Eich was told that the new language should be the scripting language companion to Java. Eich eventually settled on a language that has a C-style syntax (as does Java), yet has first-class functions. Java technically did not have first-class functions until version 8, however you could simulate first-class functions using anonymous classes. Those first-class functions are what makes functional programming possible in JavaScript. JavaScript is a multi-paradigm language that allows you to freely mix and match object-oriented, procedural, and functional paradigms. Recently there has been a growing trend toward functional programming. In frameworks such as Angular and React, you'll actually get a performance boost by using immutable data structures. Immutability is a core tenet of functional programming. It, along with pure functions, makes it easier to reason about and debug your programs. Replacing procedural loops with functions can increase the readability of your program and make it more elegant. Overall, there are many advantages to functional programming.
  • Learning to Code in One’s Own Language
    I recently published a paper with Sayamindu Dasgupta that provides evidence in support of the idea that kids can learn to code more quickly when they are programming in their own language. Millions of young people from around the world are learning to code. Often, during their learning experiences, these youth are using visual block-based programming languages like Scratch, App Inventor, and Code.org Studio. In block-based programming languages, coders manipulate visual, snap-together blocks that represent code constructs instead of textual symbols and commands that are found in more traditional programming languages.

  • Hacker Behind Massive Ransomware Outbreak Can't Get Emails from Victims Who Paid
    On Tuesday, a new, worldwide ransomware outbreak took off, infecting targets in Ukraine, France, Spain, and elsewhere. The hackers hit everything from international law firms to media companies. The ransom note demands victims send bitcoin to a predefined address and contact the hacker via email to allegedly have their files decrypted.
  • Digital signatures in package management
    Serious distributions try to protect their repositories cryptographically against tampering and transmission errors. Arch Linux, Debian, Fedora, openSUSE, and Ubuntu all take different, complex, but conceptually similar approaches. Many distributions develop, test, build, and distribute their software via a heterogeneous zoo of servers, mirrors, and workstations that make central management and protection of the end product almost impossible. In terms of personnel, distributions also depend on the collaboration of a severely limited number of international helpers. This technical and human diversity creates a massive door for external and internal attackers who seek to infect popular distribution packages with malware. During updates, then, hundreds of thousands of Linux machines download and install poisoned software with root privileges. The damage could hardly be greater. The danger is less abstract than some might think. Repeatedly in the past, projects have had to take down one or more servers after hacker attacks. The motivation of (at least) all the major distributions to protect themselves from planted packages is correspondingly large and boils down to two actions: one simple and one cryptographic.
