    • Moving Linux From One Laptop to Another

      Remember that post where I was going to convince my wife that she should let me use her macbook air for ham radio, and I'd give her a better one to use? Well, she was happy to give it a go. For fun, I thought that rather than make her work from a fresh install, I'd transfer her environment over as-is to the new computer...

      I booted the air from a USB drive and imaged the whole disk with dd. Took the image and wrote it directly to the SSD of the new laptop. It wouldn't boot, so I booted the USB distro again and ran an EFI repair. That worked, and the laptop booted into her image with nary a hitch (not any visible ones at least...)

      Of course, the partition needed to be resized, as she was going from a small NVME to a larger SSD. Booted the USB drive again and ran gparted, resized the partition, and voila. Booted right up, all the space available.

      • Its FOSS10 Reasons to Run Linux in Virtual Machines

         You can run any operating system as a virtual machine to test things out or for a particular use case.

        When it comes to Linux, it is usually a better performer as a virtual machine when compared to other operating systems. Even if you hesitate to install Linux on bare metal, you can try setting up a virtual machine that could run as you would expect on a physical machine.

      • April 2022 Web Server Survey [Ed: Microsoft lose more than 600 "top sites" this past month alone]

        In the April 2022 survey we received responses from 1,160,964,134 sites across 271,960,629 unique domains and 11,974,636 web-facing computers. This reflects a loss of 8.66 million sites and 217,000 domains, but a gain of 97,400 computers.

        Amongst the top ten vendors, nginx gained the largest number of domains and computers this month, maintaining its lead in both of these metrics. Its net growth of 537,000 domains has taken its total up to 73.8 million domains and increased its market share in this metric to 27.1%. Coupled with a net loss of 573,000 domains powered by Apache, this has culminated in nginx’s market share lead over Apache being extended from 3.63 percentage points to 4.04.

        The number of web-facing computers running nginx grew by 80,200 (+1.78%), pushing its market share up to 38.3% while Apache’s fell to 29.0%. nginx also continues to have the largest market share of sites (31.1%), despite losing more than half a million this month.

        Within the top million websites, Cloudflare made the largest gain of 3,350 sites as it continues to edge its way up towards the leaders. Apache is currently still in the lead with 229,000 sites in the top million, but lost 1,700 this month; and nginx is in second place with 218,000 sites after losing 2,250. Cloudflare now has 199,000 sites and looks set to overtake both nginx and Apache by the end of the year if it maintains this pace of growth. Amongst all websites, Cloudflare lost 38,400 sites but gained 115,000 domains.

        OpenResty was the major vendor that gained most sites this month, increasing its total by 1.47 million to 93.0 million (+1.61%), and it also gained 6,890 web-facing computers.

        While most of the top vendors lost active sites this month, Pepyaka made a significant gain of 1.22 million active sites (+27.6%). This server is predominantly used by the Wix web development platform, which switched from using nginx in 2018. It is currently the 8th most commonly used web server by active sites, and 11th by sites. Similarities in the version numbering since 2018 suggest Pepyaka is likely based on mainline releases of nginx.

        Further down the field, GHS gained 1.08 million (+36.7%) sites and 554,000 (+35.5%) domains. GHS (Google Host Server) is one of Google’s proprietary web servers, which can be used by sites registered through Google Domains. It is also still used to redirect traffic from googlepages.com sites that were created with Google Page Creator. When this website creation service shut down in 2009, existing pages were migrated to Google Sites, which hosts user content in subdirectories under the sites.google.com hostname.

      • Linux Shell TipsHow to Lock a Text File in Linux Using flock Command

        Before we explore the techniques/approaches of locking a text file under a Linux operating system environment, we should first understand the logic behind Linux’s file locking mechanism.

        Linux’s file locking mechanism restricts/controls file access among multiple processes. When a text file is successfully locked, only one process can access it on a specific time schedule.

        Before proceeding with this article, please understand that file locking is very much different from file encryption or file access control where a passphrase or password is needed to control user access to your files.

      • Linux Shell TipsHow to Parse or View XML Code in Linux Command Line

        XML is an abbreviation for Extensible Markup Language. Since XML is both a markup language and a file format, its usage is paramount in the storage, transmission, and reconstruction of arbitrary data. XML-defined set of rules makes it possible to encode documents in machine-readable and human-readable formats.

        There is a downside to XML being attributed as a human-readable language. It is challenging to read and write due to its unfriendly format. For instance, you will find it difficult to visually comprehend a single long line of XML code when it lacks element indentations.

        • EasyOS Dunfell-series 3.4.7

          EasyOS was created in 2017, derived from Quirky Linux, which in turn was derived from Puppy Linux in 2013. Easy is built in woofQ, which takes as input binary packages from any distribution, and uses them on top of the unique EasyOS infrastructure. Throughout 2020, the official release for x86_64 PCs was the Buster-series, built with Debian 10.x Buster DEBs. EasyOS has also been built with packages compiled from source, using a fork of OpenEmbedded (OE). Currently, the Dunfell release of OE has been used, to compile two sets of binary packages, for x86_64 and aarch64. The latter have been used to build EasyOS for the Raspberry Pi4, and first official release, 2.6.1, was in January 2021. The page that you are reading now has the release notes for EasyOS Dunfell-series on x86_64 PCs, also debuting in 2021. Ongoing development is now focused on the x86_64 Dunfell-series. The last version in the x86_64 Buster-series is 2.6.2, on June 29, 2021, and that is likely to be the end of that series. Releases for the Pi4 Dunfell-series are still planned but very intermittent. The version number is for EasyOS itself, independent of the target hardware; that is, the infrastructure, support-glue, system scripts and system management and configuration applications. The latest version is becoming mature, though Easy is an experimental distribution and some parts are under development and are still considered as beta-quality. However, you will find this distro to be a very pleasant surprise, or so we hope.

        • Lennart Poettering: Testing my System Code in /usr/ Without Modifying /usr/



          I recently blogged about how to run a volatile systemd-nspawn container from your host's /usr/ tree, for quickly testing stuff in your host environment, sharing your home drectory, but all that without making a single modification to your host, and on an isolated node.

          The one-liner discussed in that blog story is great for testing during system software development. Let's have a look at another systemd tool that I regularly use to test things during systemd development, in a relatively safe environment, but still taking full benefit of my host's setup.

          Since a while now, systemd has been shipping with a simple component called systemd-sysext. It's primary usecase goes something like this: on one hand OS systems with immutable /usr/ hierarchies are fantastic for security, robustness, updating and simplicity, but on the other hand not being able to quickly add stuff to /usr/ is just annoying.

          systemd-sysext is supposed to bridge this contradiction: when invoked it will merge a bunch of "system extension" images into /usr/ (and /opt/ as a matter of fact) through the use of read-only overlayfs, making all files shipped in the image instantly and atomically appear in /usr/ during runtime — as if they always had been there. Now, let's say you are building your locked down OS, with an immutable /usr/ tree, and it comes without ability to log into, without debugging tools, without anything you want and need when trying to debug and fix something in the system. With systemd-sysext you could use a system extension image that contains all this, drop it into the system, and activate it with systemd-sysext so that it genuinely extends the host system.

        • The Register UKFedora dev team starts to simplify Linux graphics handling ● The Register

          The Fedora development team are planning some significant changes to the way the distro handles graphics, which will help to push forward the state of Linux graphics support – but it may hinder troubleshooting when things go wrong.

          The planned changes are coming in two stages. Initially, the imminent Fedora 36 release will remove the old fbdev driver, leaving only DRM and KMS. Then in Fedora 37, which is due later this year, the plan is to remove the driver from the X.org server as well.

          These steps are associated with the planned transition to requiring UEFI firmware, with a later goal of removing legacy BIOS support altogether.

          Canonical just released Ubuntu Linux 22.04 last week, with a slew of new features and an extended support period of five years. Pop!_OS, one of the more popular desktop Linux distributions based on Ubuntu, has now released an update with the new Ubuntu version as the foundation.

          Pop!_OS is based on Ubuntu and uses many of Ubuntu’s packages and default applications, but with a customized version of the Gnome desktop environment that System76 calls ‘Cosmic’. There are a few other changes too, like built-in drivers for Nvidia graphics cards (if you install using the Nvidia PC installer) and a custom app store.

      • OpenSource.comHow I grew my product management career with open source

         In simple terms, open source software is software with source code that anyone can inspect, modify, enhance, and share. Opensource.com has documented a detailed and comprehensive article to help you understand what open source is.

        My discovery of open source started in the early phase of my career as a visual designer. I was curious to know what it meant and how to be a part of it and that led me to reach out to a few experienced open source contributors and advocates. Though I didn't contribute at the time, I acquired knowledge of the community which helped me when I made the decision to start contributing.

      • UbuntuOpen source technology in logistics sector [Ed: She calls GNU "Linux"...]

        The word open source was first coined by Christine Petersen to a working group that was dedicated, with a goal to share open-source software practices in the broader marketplace. The working group values sharing of software for better use, cheaper offering and preventing vendor lock-in. In addition to these values, open-source projects, products, or initiatives embrace and celebrate principles of open exchange, collaborative participation, rapid prototyping, transparency, meritocracy, and community-oriented development.

        A good example of open source is Linux, which became the largest open-source software project in the world. It is a free, open-source Operating System (OS), released under the GNU General Public Licence (GPL). Linux licence prevents restrictions on the use of the software, anyone can run, study, modify, and redistribute the source code, or even sell copies of their modified code, as long as they do so under the same licence.

        • Adriaan de GrootLinux Application Summit 2022

          It’s happening! Yes, Linux App Summit (LAS) 2022, but more in particular a gradual return to hybrid conferences – a mix of in-real-life and virtual. I’m looking forward to seeing .. no, more than just seeing, but touching .. friends from GNOME, from KDE, from CHAOSS, and the rest of the Free Software world again. OK, “touching” sounds creepy. I’ll ask consent first, which is the least I can do to satisfy the Code of Conduct. Maybe I’ll check the slides of the impromptu lightning talk I gave in 2019 as well.

          Going to a physical event feels weird. It feels semi-safe. I know a lot of the people there, I look up to many, I assume everyone is smart, capable and looking out for the good of the world-as-a-whole. Getting together is not-quite-the-safest-thing-to-do. Though it’s likely to be a dang lot safer than regular train travel in the Netherlands, where every precaution has been scrapped because the pressure on health care is “low enough”. Italy is still being fairly careful. But enough about travel restrictions, let’s look at the timetable.

            You probably have already heard about WebAssembly, but there are high chances that happened in the context of Web application development. There’s however a new emerging trend that consists of using WebAssembly outside of the browser.

            WebAssembly has many interesting properties that make it great for writing plugin systems or even distributing small computational units (think of FaaS).

            WebAssembly is what is being used to power Kubewarden, a project I created almost two years ago at SUSE Rancher, with the help of Rafa and other awesome folks. This is where the majority of my “blogging energies” have been focused.

      • Supporting metafile formats: WMF/EMF/EMF+

        LibreOffice supports many file formats, and among them are some raster and vector image formats from Microsoft. Metafile formats WMF, EMF and EMF+ are among the vector formats usable in Microsoft products, and also in LibreOffice. Here we discuss the implementation of the support for these file formats in LibreOffice.

        We call these file formats metafiles, as they are means of storing drawing commands that are calls to the Windows API that draws shapes and text on the screen. It is possible to replay these metafiles to have a graphical output in an appropriate context.

        It is possible to create complex shapes using metafiles. For example, if you take a look at the odk/examples/basic/forms_and_controls folder in the LibreOffice source code, you will see some nice examples. Here is one of them: A delicious burger created using vector primitives.

          • Hacker NewsMicrosoft Discovers New Privilege Escalation Flaws in Linux Operating System [Ed: Microsoft concern-trolling Linux while putting NSA back doors in Windows]

            Microsoft on Tuesday disclosed a set of two privilege escalation vulnerabilities in the Linux operating system that could potentially allow threat actors to carry out an array of nefarious activities.

          • Microsoft finds Linux desktop flaw that gives root to untrusted users [Ed: As if local privilege escalation is anywhere as severe as remotely-reachable back doors in Windows. Microsoft is "concerned" about Linux security like wolves are concerned about the safety of sheep.]

            Vulnerabilities recently discovered by Microsoft make it easy for people with a toehold on many Linux desktop systems to quickly gain root system rights— the latest elevation of privileges flaw to come to light in the open source OS.

          • Bleeping ComputerNew Nimbuspwn Linux vulnerability gives hackers root privileges [Ed: While CISA admits Microsoft is full of holes that are actively exploited Microsoft and its faithful media operative try to shift attention to "Linux"]

            Security researchers at Microsoft disclosed the issues in a report today noting that they can be chained together to achieve root privileges on a vulnerable system.

          • “Dirty Pipe” Linux vulnerability now being exploited [Ed: This was patched a very long time ago; meanwhile, there are dozen of zero-day flaws in Windows that are remotely exploitable, not local privilege escalation]

            The Linux vulnerability dubbed Dirty Pipe is now being actively exploited in the wild, CISA has confirmed. (Assigned CVE-2022-0847 and first publicly disclosed on March 7, the escalation of privileges (EOP) vulnerability exists in all Linux kernel versions from 5.8 forward and lets a read-only attacker gain root.)

          • Russell CokerRussell Coker: PIN for Login [Ed: Microsoft gives the NSA et al direct access to PCs, so no "security" measures from Microsoft should be taken seriously]

            A PIN in concept is a shorter password. I think that less secure methods of screen unlocking (fingerprint, face unlock, and a PIN) can be reasonably used in less hostile environments. For example if you go to the bathroom or to get a drink in a relatively secure environment like a typical home or office you don’t need to enter a long password afterwards. Having a short password that works for short time periods of screen locking and a long password for longer times could be a viable option.

            It could also be an option to allow short passwords when the device is in a certain area (determined by GPS or Wifi connection). Android devices have in the past had options to disable passwords when at home.

You have to deal with absurd delays between each mouse click and the browser quiescing to the point where it might be safe to make the next move, and things just judder around uncontrollably and incoherently on-screen, with no indication of what's going on.
