Chrome OS 84 tweaks Linux setup to include username and container sizing options

Filed under

Google

When Google introduced Chrome OS back in 2011, it was mostly just a window to the web. The operating system eventually expanded to include Android integration, and last year Google announced that every new Chromebook would be launching with Linux support. However, the implementation of Linux on Chrome OS had been a little limited out of the gate. Now with the launch of Chrome OS 84, Google is adding the ability to set a username and configure the Linux disk size during initial setup.

Previously, it was possible to adjust the size of the Linux container, but it required setting up a fresh installation. The Chrome OS team has been working on this change for several months now, and it's finally landing in the Stable channel. With this update, users will be able to resize the Linux container without having to remove it and re-do the installation.

Why Computer Science Students Should Use the GNU/Linux-Based OS

Filed under
GNU
Linux

Modern technologies develop in the blink of an eye, and every fresh computer science student eventually learns to solve issues with new operating systems (OS). Even if it is said that famous operating systems like Windows or iOS are similar, their editions in 2020 are not the same as what they used to be ten years ago. There has been enough time to figure out all the pros and cons of each OS. Therefore, it is time to speak about the reasons computer science students prefer GNU/Linux to any other OS.

[...]

The central part of it is the GNU/Linux kernel that runs on more different kinds of hardware than any other firmware or OS. If you want to use a command-line on different non-Linux based systems, use bash integration with its terminal to work in a similar environment. The Linux kernel provides a common platform for software and supports various hardware architectures. Linux can run on any hardware type: from tiny laptops with micro-controllers to powerful supercomputers.

[...]

Computer science students have a great opportunity to quench their curiosity with the GNU/Linux system. If the source is open and free, it is a crime to avoid learning it. Even if you compare the Linux OS with other famous tools, you definitely will not regret to know how it works. Who knows, maybe it is a first step to creating your own operating system

    It looks like the Raspberry Pi family is about to get a big performance boost, with Eben Upton’s announcement that the upcoming Pi Compute Module 4 will hopefully support NVMe storage. The non-volatile memory express spec will allow speedy access to storage and make the many hacks Pi users use to increase access speed unnecessary. While the Compute Modules are targeted at embedded system designers, Upton also hinted that NVMe support might make it into the mainstream Pi line with a future Pi 4A.

GNU GCC: Project Ranger Status

Filed under
Development
GNU
  • Project Ranger Status
    We originally intended to start pushing ranger code into trunk shortly 
    after the start of stage 1, but of course.. delays, delays :-)
    
    So here is the latest status/changes since last fall and our proposed 
    time-line going forward.  I'll do the executive summary here, and more 
    details at each submission stage.
    
    
    1) multi-range support - Imminent
    
    We have moved the representation of our multi-range class  from wide-int 
    to trees, and merged it with the value_range class .  There is now a 
    base class which "recognizes" a 1 sub-range case as a special legacy 
    mode which supports ANTI_RANGE and incorporates the original value_range 
    code.  Multi-range is fully interoperable/compatible with value_range 
    code now and all existing code which uses value_range still operates 
    exactly the same as it did.. its just slightly different under the covers.
    
    range-ops has been returned to working in multi-range mode again now 
    that its compatible with value_range. Any consumer working with ranges 
    can switch to multi-range by switching to the multi-range API.
    
    This code is currently going through a complete fedora build, and 
    assuming that passes, Aldy will be submitting it for trunk along with 
    various details and performance results in the coming week or so.
    
    
    2)  Ranger - Mid August
    
    The on-demand ranger has been substantially simplified, with well 
    defined components contained in just a few source files.    It is queued 
    up for trunk submission after the multi-range code goes in..
    
    Initially, we plan to enable it for a few client passes which we will 
    describe at submission time (mostly the same passes as last years 
    presentation discussed) , along with a VRP pass which will run 
    immediately before EVRP called RVRP.  It uses the same dom-walking 
    infrastructure that EVRP uses, but it still has a lack of relational 
    processing (to be addressed next)
    
    At submission time I'll provide the details, as well as performance and 
    shortcomings once it has also passed thru a fedora build cycle. This 
    will also include the test suite adjustment strategy.
    
    
    3) Equivalency/Relational Processing - Mid September(?)
    
      Finally, the relation code will come, probably in mid September. The 
    proof of concept oracle prototype looked good, so I'm re-working parts 
    of it for performance in production code.
    
    Once the relation code is in place, we will work on whatever remaining 
    differences there are between EVRP and the new RVRP pass.
       - with RVRP running immediately before EVRP, we can identify anything 
    EVRP finds of significance that is missed.
       - We can also run RVRP immediately after EVRP  and identify things 
    RVRP gets which EVRP does not.
    
    -------------
    
    We know we get immediate benefit from multiple passes when they are 
    switched to ranger, and we'd like to get that enabled ASAP  allowing the 
    code to be rigorously exercised during the rest of stage 1.
    
    The RVRP pass will be a work in progress, and it is 100% self contained 
    in one file, simply operating as a ranger client just like the other 
    passes.   If we reach the end of stage 1, and for whatever unforeseen 
    reason RVRP is not performing satisfactorily enough to replace EVRP, we 
    simply turn it off.  If it is operating well enough, then we turn of 
    EVRP.  We can decide towards the end fo the stage.
    
    
    Thats a quick synopsis of the current ranger work. Over the next 2 
    months we hope to get all of the components into trunk and available for 
    general use.
    
    Andrew & Aldy
    
  • GCC's New Ranger Infrastructure Aims To Be In Good Shape For GCC 11

    Making waves just over a year ago in the GNU Compiler Collection community was the "Ranger" project for on-demand range generator that's been worked on for several years at Red Hat. While their goals for GCC 10 didn't pan out, it's looking like in the next few months more of the Ranger infrastructure will land and thus putting it in the window for GCC 11.

    Ranger allows for querying range information on-demand for SSA names/variables from within anywhere in the IL with minimal overhead, among other benefits to the compiler internals.

Today, there’s a virtual classroom with the teacher, where everyone will be able to easily communicate together using Jitsi, just inside their Firefox web browser. Some educational materials are needed, of course, which she can easily grab from the university’s central LMS (Learning management system), powered by Moodle; A fully free and open source software.

Fatma, like many university students in her country and also like most students of the world in the age of Coronavirus, found the transition to a more digitalized education very accessible and very hassle-free, thanks to the efforts of open source developers which had been accumulating over each other for the past few decades.

Open Hardware With Arduino: Counter and MKR ZERO

  • Keep track of your laps in the pool with this Arduino counter

    PeterQuinn925 swims for exercise, and to train for the occasional triathlon, but when doing so he often zones out and forgets how many laps he has swam. To solve this problem without spending a lot of money on a commercial solution, he created his own counter using an Arduino Nano and an ultrasonic sensor. The sensor detects when a swimmer approaches, and the system calculates distance based on this, assuming that a lap is roughly 50 yards or meters. This info is announced audibly via a speaker/amplifier using an Arduino speech library and is shown on a 7-segment display.

    While 2020 may seem like a very futuristic year, we still don’t have robotic maids like the Jetsons’ Rosie the Robot. For his latest element14 Presents project, DJ Harrigan decided to create such a bot as a sort of animatronic character, using an ESP8266 board for interface and overall control, and a MKR ZERO to play stored audio effects. The device features a moveable head, arms and eyes, and even has a very clever single-servo gear setup to open and close its mouth.
