      • Make Linux look like Windows 10

        As the days pass, Linux is on its way to becoming the go-to operating system for users. With its superior command-line interface, better security, and a helpful community that offers support and fixes for most issues, no doubt switching to Linux-based distributions seems like a tempting option.

        If you’re coming from a Windows 10 background, switching to the graphical user interface (GUI) of Linux would seem like unknown territory to you. Navigating through the unfamiliar GUI might be a little confusing.

        If we just described your situation, then fear not; the purpose of this guide is to make sure that you get that familiar OS feeling of Windows 10 on your Linux system. With all that out of the way, let’s take a look at the methods to make Linux look like Windows 10.

      • Examining btrfs, Linux’s perpetually half-finished filesystem

        Btrfs—short for “B-Tree File System” and frequently pronounced “butter” or “butter eff ess”—is the most advanced filesystem present in the mainline Linux kernel. In some ways, btrfs simply seeks to supplant ext4, the default filesystem for most Linux distributions. But btrfs also aims to provide next-gen features that break the simple “filesystem” mold, combining the functionality of a RAID array manager, a volume manager, and more.

        We have good news and bad news about this. First, btrfs is a perfectly cromulent single-disk ext4 replacement. But if you’re hoping to replace ZFS—or a more complex stack built on discrete RAID management, volume management, and simple filesystem—the picture isn’t quite so rosy. Although the btrfs project has fixed many of the glaring problems it launched with in 2009, other problems remain essentially unchanged 12 years later.

      • Google is bringing Android closer to the Linux kernel

        Google has shared more details about how it aims to bring the Android kernel a lot closer to the mainline Linux kernel with the impending release of Android 12.

        The news came courtesy of a presentation at the Linux Plumbers Conference by Google’s software engineer Todd Kjos.

        Commenting on the development, Ars Technica shares that typically the mainline Linux kernel goes through three major forks before it is shipped to the end users on an Android device.

      • SiFive HiFive Unmatched Hands-On, Initial RISC-V Performance Benchmarks

        A few weeks ago I finally received the HiFive Unmatched from SiFive as their flagship RISC-V development board. As a reminder this is their mini-ITX development board that is powered by their U740 SoC and features 16GB of DDR4 system memory, one PCI Express x16 slot that can work with AMD Radeon graphics cards on Linux, and other features. It’s been a delight playing with this developer platform and enclosed are some early benchmarks as well showing off the U740 performance as well as how the Linux software support/performance has been evolving.

        The SiFive HiFive Unmatched is what many developers and enthusiasts have long been waiting for and began shipping this summer after being announced at the end of last year. The mini-ITX board is powered by a 24-pin ATX power supply connection, the PCI Express x16 slot (at PCIe x8 speeds) can power a graphics card if wanting to use this board as a workstation, 16GB of DDR4 is sufficient for most of today’s development needs, there is integrated Gigabit Ethernet, both microSD and NVMe M.2 storage support, one M.2 E-key slot for WiFi/Bluetooth, and four USB 3.2 Gen1 ports.

    • How To Zoom Tmux Panes For Better Text Visibility In Linux – OSTechNix

      I have been using GNU Screen and Tmux terminal multiplexers for many years now. They comes in handy when performing different tasks in multiple terminal windows simultaneously. Today I learned one of the useful feature of Tmux – Zooming panes. Yes, we can zoom Tmux panes to fit them into the full size of current Terminal window for better text visibility and for viewing more of its contents.

      It is useful when you need more space or focus on a specific task. After finishing that task, you can zoom out (unzoom) the Tmux pane back to its normal position or size.

    • Common Apache Commands on Ubuntu & Debian – TecAdmin

      Apache is the most popular web server developed by the Apache Foundation in 1995. It comes under Apache License 2.0. It is a cross-platform application available for most of the older operating systems like Linux, Windows, and macOS systems. With a 45% of market share, Apache is serving almost every second website on the internet. Which tells its popularity between users.

      In this tutorial, we will discuss some commonly used commands for managing Apache servers on Ubuntu and Debian-based systems. This includes how to enable/disable a virtual host, module, or configuration file in the Apache server.

    • Use DVD as Local Repository in CentOS 8

      Appstream (Application Stream) and BaseOS are the two repositories that ship with CentOS 8. Centos 8 has two repositories, and they are different from one another. Among AppStream’s components are software packages such as databases and dependencies. BaseOS repository provides requisite packages, which are useful for an operating system that is minimal. If you also want to use DVD as a Local repository, then go through this article because we have written everything regarding CentOS use DVD as local repo.

    • how to tail logs in kubectl

      For container orchestration, Kubernetes has now become the industry standard. It provides the needed abstraction for successfully administering large-scale containerized systems with clear configurations, a straightforward deployment method, and scalability abilities. Like any other system, Logs allow developers to gain visibility into containers and the Kubernetes clusters they are operating on, and their importance is clear in many Kubernetes failures. However, Kubernetes presents a distinct set of logging issues. Application logs can assist you in figuring out what’s going on inside your app. The logs are very helpful for troubleshooting and tracking cluster activities. A logging feature is present in almost all current programs. Container engines, too, are built to handle logging. Publishing to standard output and standard error streams is the simplest and most often used logging option for containerized applications. These logs show you what’s happening and can be useful for debugging master node issues. Unfortunately, these logs cannot be viewed via the kubectl command; instead, they must be viewed directly from the computer. You may need to SSH into the node directly, based on where you are hosting the computer. This understanding enables you to observe the relationships between these resources and the consequences of one action upon another. In this guide, we are checking different ways to tail logs in kubectl. To execute this whole process, we are utilizing Ubuntu 20.04 LTS. We have installed and started the minikube cluster. Also, kubectl is already installed and configured on our system.

    • How to Replace Substring in Bash Natively

      Here’s the scenario. You have a big string and you want to replace part of it with another string.

      For example, you want to change “I am writing a line today” to “I am writing a line now”.

      In this quick tutorial, I’ll show you how to replace a substring natively in Bash. I’ll also show the sed command example as an extension.

    • SS Command in Linux with Useful Examples

      The ss tool is a CLI command used to display information about the network socket in Linux. The ss stands for socket statistics. It is a similar tool to netstat, which can display more information such as TCP and state information.

      The ss tool comes with the iproute2 package. It can display stats for PACKET, TCP, UDP, DCCP, RAW, and Unix domain sockets.

      In this tutorial, we learn ss command in Linux with useful examples.

    • Atheros Wireless in Alma, CentOS and Rocky Linux

      Not that long ago, I took AlmaLinux for a second spin, this time for a more detail review of the distro on my brand-newish IdeaPad 3 machine. Things went reasonably well, except one big glaring problem. I didn’t have Wireless connectivity, right after the installation. This is major, because you can’t really use a modern system without (some) network, especially this early on.

      Soon, I spent a couple of hours trying to fix this. The problem turned out to be rather quirky. Supposedly, I did have all the right drivers and whatnot, but the system couldn’t really utilize the hardware. A combination of two factors contributed to the issue, which we will solve in this tutorial.

    • How To Install AnyDesk on Debian 11 – idroot

      In this tutorial, we will show you how to install AnyDesk on Debian 11. For those of you who didn’t know, Anydesk is a remote desktop application. It is a cross-platform software that provides platform independent remote access to different PCs and other host devices. It provides remote access, file transfer, VPN features. It provides secure and reliable access to IT professionals.

      This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of the AnyDesk remote desktop application on a Debian 11 (Bullseye).

    • How Do You Check ZSH History

      As Linux power users, we often come across instances where we need to rerun specific commands. Although some are simple commands that we can retype, some are complex and messy regular expression queries that will take time to reconstruct.

      In such scenarios, we can use our shell command history to scroll through our previous commands or use the reverse search to search for a specific command using the up and down arrows.

      This tutorial will discuss ways to find and reuse our previous commands using the ZSH command history feature.

    • How Do I Zoom In and Out on My Bluestacks Emulator? [Android]

      Over the years, we have seen the rise and fall of many android emulators. However, there is one that has been the king: Bluestacks Emulator.

      Bluestacks is an android emulator that uses virtualization technology to emulate android devices on Windows and macOS systems. It offers modern features to run modern games and applications with minimal or no compatibility issues.

      Zooming in and out of Bluestacks may seem impossible, especially if you are emulating an app or game that requires a touch display.

    • How to Configure Apache Tomcat in Linux

      Apache Tomcat, or simply Tomcat, is a free and open-source web server developed by the Apache Software Foundation to implement Java Servlet, JavaServer Pages, Java Expression Language, and web-socket technologies. It provides a ‘pure Java’ http server.

      Apache Tomcat provides a default HTTP connector on port 8080, allowing you to use it as a web server such as Apache for your Java applications.

    • How to Configure mod_jk in Apache HTTP Server

      Mod_jk is an Apache module or connector that connects the Apache Tomcat Servlet container with web servers such as Apache, IIS, and more. The mod_jk is a complete replacement of the older mod_jser module that handles communication between Tomcat and HTTP servers using Apache JServ Protocol.

      We will not get into the deeper workings of the mod_jk module as it is beyond the scope of this tutorial. Instead, we shall focus on how to integrate it with the Apache HTTP Server.

      Every sysadmin should know how to implement scripts to automate their workflow. Although we have many automation tools such as Ansible, scripting remains a critical tool to automate tasks in the Linux world.

      This tutorial will look at loops, a fundamental concept in scripting and programming in general. We will specifically focus on how for loops work.

    • How to Enable Debug Logging in Apache

      As a system administrator, you will need to understand what is going on under the hood of various services in your system. Logging is probably the best way to do that.

      Logs allow you to collect information about the services and applications running on your system and save that log to a file for future use.

      This tutorial will learn how to collect detailed information about the Apache Tomcat service by enabling the DEBUG mode.

    • How to Encrypt Storage Drives Using LUKS in Linux

      This article will cover a guide on using the “Linux Unified Key Setup” or LUKS encryption standard that can be used to create encrypted and password protected storage drives. During encryption, LUKS reserves a space on the storage drive and stores necessary information required for encryption and decryption on the storage drive itself. This on-disk encryption methodology ensures near plug and play compatibility across Linux distributions and easy transferability of data drives. As long as you have LUKS installed on your Linux system and you know the password, you will be easily able to decrypt any LUKS encrypted data drive on any Linux distribution.

    • How to Install Apache, MariaDB, PHP7 (LAMP) on openSUSE Leap 15.3 – Unixcop

    • How to Install Arch Linux: Beginner’s Step-by-Step Installation Guide

      Arch Linux is not difficult to install. In this guide I will going to show you how to easily install Arch Linux with the GNOME Desktop Environment.

      Many Linux users really want to give Arch Linux a try, but the general notion that Arch is difficult to learn stops many of them. When people say it’s “hard,” they really mean that it takes effort. And they’re right – you do have to put a little bit more effort into installing your system, setting everything up, and reading about how to do what you want to do.

      However, you end up with a system you understand very well and set up just the way you want it. Once installed, Arch Linux is as easy to run as any other distro, if not easier.

      You can install Arch Linux directly to your computer by following this guide, but you can also install it on a virtual machine by using VirtualBox. This Arch Linux how to installation guide shows the whole process in easy-to-follow steps.

      Nagios is a powerful tools that allows you to monitor your IT infrastructure and notify you if any hosts, service or machine specs are malfunctioning. We will see to monitor a linux machine’s basic health check e.g. Current load, Disk Space and Ram Usage etc. in this tutorial.

    • How to Remove (^M) Characters from a File in Linux

      A common functional uniqueness of different operating system environments is in the way they handle and process data. This functionality is in the way a file’s text data is perceived and processed.

      For instance, you can have a normal text file created and populated under a Windows computing environment but once that same file is transferred to a Linux computing platform, it is processed and displayed differently.

      There is a logical explanation for these transferred text file’s misbehavior. On a Windows computing environment, the OS acknowledges the presence of a new line within a text file through a specific carriage return.

      While the representation of this carriage return (CR) character is hidden from the eyes of these Windows users, transferring this file to a Linux computing environment exposes it as ^M characters.

    • How to Rename Files in Linux (mv and rename Commands)

      Renaming files in Linux is a very common operation.

      In this article, we will discuss how to rename single or multiple files using the mv and rename commands in various Linux distributions.

    • How to Use Rc.local on CentOS 8

      During the boot process of Linux, we start the script using rc.local. Due to the complex init script process, it causes the user to spend a lot of time using it. Many people look for the methods to use rc.local on CentOS 8 easily. That’s why we have written this blog to give you a brief on the ways to use rc.local on CentOS 8.

    • How to Use fdisk Command to Create Partition in Linux

      The fdisk command utility is useful for viewing and editing hard disk or SSD partitions on Linux and its distributions, such as Ubuntu. It is one of the most powerful tools to manage disk partitions on Linux. Other tools are also available to perform disk partition on Linux, but fdisk is one of the most commonly used ones.

      fdisk is a menu-driven command-line utility, and hence new users find this tool confusing and difficult to use. fdisk is not an easy tool to use and should be used with caution. You need to have root access or sudo privileges to make changes to storage partitions.

      So, today in this article, I will give you a tutorial on how to create a partition in Linux using the fdisk command.

    • How to Use nmcli in Ubuntu

      Network manager manages all the network settings of the computer. With which network a machine should be connected, which type of traffic should be allowed and how to save data from the online servers are all managed by the network manager. Network managers have different tools, for example we have nm-connection-editor, nmcli, nm Gnome etc. All the tools or utilities have their own specific functions like nm-connection-editor is used to manage the wired connections of the machine, by Gnome settings we can manage all the network settings easily, by nmcli we can do the setting by the command line mode.

      This write-up will demonstrate the installation of the network manager then in detail we will discuss the nmcli command for what purpose and how it can be used.

    • How to install Apache Tomcat on Debian 11

      This tutorial explains how to install Apache Tomcat on Debian 11, its predecessors, and Debian-based Linux distributions.

      Before writing a tutorial for Linux Hint, I always check other blogs’ content in order to make ours better. This time I was surprised that no available tutorials on installing Apache Tomcat on Debian 11 included the apt-get installation method, which is easier to execute. Therefore I decided to include both methods: Installing Tomcat on Debian 11 using apt and Tomcat manual installation.

    • The Waydroid project develops a package to run Android on GNU / Linux

      The project Waydroid has prepared a toolkit that allows you to create an isolated environment in a regular Linux distribution for loading a complete system image of the Android platform and organize the launch of Android applications with it. The code of the toolkit proposed by the project is written in Python and is released under the GPLv3 license. Ready packages are generated for Ubuntu 20.04 / 21.04, Debian 11, Droidian and Ubports .

      The environment is built using standard technologies to create isolated containers such as namespaces for processes, user IDs, networking subsystem, and mount points. The toolkit is used to manage the container LXC . To run Android on top of a regular Linux kernel are loaded , the modules binder_linux and ashmem_linux .

      The environment is designed to work with a session based on the Wayland protocol. Unlike the similar environment Anbox , the Android platform provides direct access to hardware, without additional layers. The proposed Android system image for installation is based on assemblies from the project LineageOS and Android 10 .

      BattlEye is making this opt-in for game developers who wish to support its usage under Wine / Proton.

    • Epic Games Announces Easy Anti-Cheat Support for Linux, Wine, Proton, and Steam Deck

      One of the main obstacles Linux Gaming faces are anticheats, which make it impossible for Open Source users to play many titles online (and in some cases also block single-player modes). Luckily, there has been an important advance in this area recently, since Epic Games has announced the support of Easy Anti-Cheat for Linux, Mac and Steam Deck (sic), covering, of course, the Wine and Proton compatibility layers (the second is nothing more than a re-implementation of the first).

      Yes, as you are reading, Epic Games already gives official support for Easy Anti-Cheat for Linux and Wine, or at least that is how it has been announced on the company’s developer website . In recent years, the relationship between Epic Games and the Linux community has deteriorated considerably, mainly due to the fact that the corporation still does not give official support for its game store and the presence of the aforementioned Easy Anti-Cheat, which has made it impossible to Linux users play every title that has implemented it.

    • Epic Brings Easy Anti-Cheat Support For Proton and Wine On Linux!

      There’s no denying the fact that Linux gaming has improved to a great extent over the past few years. This was made possible through the Proton compatibility layer, which translates Windows DirectX to Vulkan. As of today, over 16,000 games can be played on Linux.

      But one of the areas where Linux gaming takes a hit is when running games with anti-cheat mechanisms. Today, that changes, thanks to Epic games bringing Easy Anti-cheat support to Proton and Wine on Linux. Here’s everything you need to know about the same.

    • A first Release Candidate for Proton 6.3-7 is up with more games working

    • All You Need to Know About Linux Gaming

      Windows is a de facto operating system for PC gamers, and most gamers consider Linux for gaming a distant possibility. While for some gamers, it is not the first choice. But the closed source nature and handling of personal data on Windows is an off point for many. Even though Linux distributions are not as optimal for gaming as Windows, some gaming-specific distributions and platforms have open doors of possibilities.

      The article explains the distant possibility of Linux gaming turning into reality by answering some potential questions of games compatibility with Linux and Linux suitability. We also discuss various platforms that support native, Windows, terminal, and browser-based games in Linux.

      • CutefishOS: Unix-y development model? Check. macOS aesthetic? Check (if you like that sort of thing)

        One of the reasons Linux has never caught on as a desktop operating system, as Linux fans know, is that Linux isn’t a desktop operating system, it’s a kernel. And assembling it into a coherent package users can install is the job of a distribution.

        This is a very different distribution model than the one Apple or Microsoft uses, and it confuses newcomers. Windows and macOS are easier to understand, they are single things made by single companies. Canonical and Red Hat notwithstanding, Linux is not packaged and presented this way at all. I’ve long believed that this difference is one of the key stumbling blocks to wider Linux adoption.

        Apple has macOS, Microsoft has Windows, Linux has… hundreds of awkward, confusingly named options.

        This is both Linux’s greatest strength, and its greatest weakness. For those who already understand and use it the options are welcome. I’ve been a Linux user for over a decade and I’ve used several dozen distros, some of them so different from one another it’s difficult to believe they’re built from the same base. This wealth of options is great, but it’s both confusing and overwhelming for new users.

        Distributions like elementary OS are popular with people switching from macOS and Windows because elementary OS offers that same highly polished, all-in-one package that makes the transition from proprietary operating systems smoother. But this is Linux, so you can’t just have elementary OS.

        The latest distro to catch my eye is CutefishOS, which owes considerable design debt to both elementaryOS and the operating system made by that fruit company.

      • MidnightBSD 2.1.0 Available to Download

        Lucas Holt has announced the release of MidnightBSD 2.1.0, the latest stable build of the project’s FreeBSD-derived operating system for desktops: “I am happy to announce the availability of MidnightBSD 2.1 for amd64 and i386.

        This is an incremental release focusing on bug fixes, improvements to the package manager and a new system compiler. LLVM updated to 10.0.1, mport 2.1.4. The majority of improvements come from the MidnightBSD package manager, mport. A number of long-standing bugs have been fixed. It now can update dependencies properly on install, update or upgrade scenarios. Previously, it would sometimes crash and force the user to do it manually. Several fixes have been made around PLIST processing. The mport utility now sets a character encoding so that extracting files with libarchive with special characters is more likely to work properly without a crash occurring. (lang/go port is a fun trigger of this bug). The libmport library no long relies on libdispatch. This is slower in a few scenarios, but most invocations are now faster as it doesn’t need to setup the thread pools or do the locking it once did.” See the release notes for a full changelog, upgrade instructions and known issues.

      • MidnightBSD 2.1 Released For This Desktop-Minded BSD

        MidnightBSD 2.1 debuted this week as the latest version of one of the few desktop-focused BSD open-source operating system projects.

        MidnightBSD 2.1 updates to the (somewhat out of date still) LLVM 10.0.1 compiler stack, moves to mport 2.1.4 for a newer version of its package manager, and has a number of other bug fixes and security updates. The mport package manager update in particular should address a number of problems previously plaguing MidnightBSD users.

        Unlike other FreeBSD desktop builds, MidnightBSD was originally developed as a fork of FreeBSD 6.1-beta, which was synchronized with the FreeBSD 7 codebase in 2011 and later incorporated many of the features from FreeBSD 9, 10, and 11. For package management MidnightBSD uses the mport system, which uses a SQLite database to store indexes and metadata. Installing, removing and searching for packages is carried out using a single command mport .

        Today we are going to play a bit around with the amazing API that every openQA instance provides. The aim of this tutorial is to show how the API can be accessed using a simple language like python. More advanced topics like job posting, deletion and other methods that require authentication are possible but not covered extensively in this post. The reference for this post will be openqa.opensuse.org, but everything works pretty much with every openQA instance.

      • openSUSE Tumbleweed – Review of the weeks 2021/38

        This week we have shipped the long-awaited glibc 2.34 update. Unfortunately, as was the case with earlier glibc updates, some containerization methods are blocking new syscalls, which can lead to issues out of the control of Tumbleweed. Our docker packages have been adjusted to handle Tumbleweed inside the containers, but many container providers might not be there yet. Besides the full rebuild snapshot with glibc, we released a total of 4 snapshots this week (0916, 0920, 0921, and 0922).

      • Fedora Workstation: Our Vision for Linux Desktop

        So I have spoken about what is our vision for Fedora Workstation quite a few times before, but I feel it is often useful to get back to it as we progress with our overall effort.So if you read some of my blog posts about Fedora Workstation over the last 5 years, be aware that there is probably little new in here for you. If you haven’t read them however this is hopefully a useful primer on what we are trying to achieve with Fedora Workstation.

        The first few years after we launched Fedora Workstation in 2014 we focused on lot on establishing a good culture around what we where doing with Fedora, making sure that it was a good day to day desktop driver for people, and not just a great place to develop the operating system itself. I think it was Fedora Project Lead Matthew Miller who phrased it very well when he said that we want to be Leading Edge, not Bleeding Edge. We also took a good look at the operating system from an overall stance and tried to map out where Linux tended to fall short as a desktop operating system and also tried to ask ourselves what our core audience would and should be. We refocused our efforts on being a great Operating System for all kinds of developers, but I think it is fair to say that we decided that was to narrow a wording as our efforts are truly to reach makers of all kinds like graphics artists and musicians, in addition to coders. So I thought I go through our key pillar efforts and talk about where they are at and where they are going.

        IBM engineer Daniel Axtens presented at this week’s Linux Plumbers Conference on the prospects of using the Rust programming language for creating modules for the GRUB2 boot-loader.

        The proposal is not about rewriting GRUB2 in Rust or transitioning it in any large part to Rust, but allowing GRUB2 modules to be created in Rust if so desired by developers. Similar to the growing number of other projects adopting Rust, the motivation is on the prospects of safer code compared to C.

      • IBM’s IWB: Realizing the Economic Promise of Predictive Analytics

        Wikipedia defines predictive analytics as a set of statistical techniques, – such as data mining, business analytics, and machine learning, – “that analyze current and historical facts to make predictions about future or otherwise unknown events.” Increasingly powerful and inexpensive computing technologies, new algorithms and models, and huge amounts of data on almost any subject have led to major advances in predictive analytics over the past two decades.

        “Worldwide revenue for ‘big data’ and business analytics solutions is forecasted to reach $274.3 billion by 2022,” wrote economists Erik Brynjolfsson, Wang Jin, and Kristina McElheran in The Power of Prediction, a research article published earlier this year. In principle, such widespread use of predictive analytics should have a positive impact of the performance of firms. “However, these investments have yet to yield productivity gains in the aggregate,” said the authors. “At the firm level, managers struggle to close the gap between the promise of predictive analytics and its performance. These concerns have been difficult to tackle empirically due to the rate of technological change and, ironically, a dearth of data.”

        To address these concerns, the authors launched a research study in collaboration with the US Census Bureau to collect information on the use of predictive analytics in a representative sample of the US manufacturing industry, – an industry that’s historically been an early adopter of leading-edge technologies.

      • Ubuntu Linux 21.10 ‘Impish Indri’ Beta is here

        Happy Friday, dear BetaNews readers! The weekend is almost here, so hopefully you can take some time to do the things you want to do, rather than the tasks your boss or teacher makes you do. For some, that means spending time with family, watching movies, or resting up. For nerdier people, it is an excellent time to test a Linux distribution!

        Today, Canonical releases the official beta version of the upcoming Ubuntu 21.10 Linux distro. Code-named “Impish Indri,” the operating system features Linux kernel 5.13. Also notable, the Firefox browser that comes with Ubuntu 21.10 is a Snap rather than a typical deb — this may prove controversial for some.

        “Ubuntu 21.10, codenamed ‘Impish Indri,’ continues Ubuntu’s proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution. The team has been hard at work through this cycle, introducing new features and fixing bugs,” says Brian Murray, Canonical.

      Open Source Software, since its birth, has made people wonder about its effects. The debate is never-ending, and for the right reasons. Giants like Apple have often viewed Open Source skeptically because they are mostly unfounded. However, one cannot deny that these sources are functional and flexible. They are also partly responsible for bringing the technological world in the right direction. But are they worth it?

        Last week we had our most loved annual conference: X.Org Developers Conference 2021. As a reminder, due to COVID-19 situation in Europe (and its respective restrictions on travel and events), we kept it virtual again this year… which is a pity as the former venue was Gdańsk, a very beautiful city (see picture below if you don’t believe me!) in Poland. Let’s see if we can finally have an XDC there!

        [...]

        Big shout-out to the XDC 2021 organizers (Intel) represented by Radosław Szwichtenberg, Ryszard Knop and Maciej Ramotowski. They did an awesome job on having a very smooth conference. I can tell you that they promptly fixed any issue that happened, all of that behind the scenes so that the attendees not even noticed anything most of the times! That is what good conference organizers do!

        • Google Chrome 94 Released with Sharing Hub feature

          Google has unveiled the release of the Chrome 94 web browser . At the same time , a stable release of the free Chromium 94 project is available , which serves as the basis for Chrome. The Chrome browser is distinguished by the use of Google logos, the presence of a system for sending notifications in case of a crash, modules for playing protected video content (DRM), a system for automatically installing updates and transmitting RLZ parameters when searching . The next release of Chrome 95 is scheduled for October 19th.

          Starting with the release of Chrome 94, development has been moved to a new release cycle. Significant new releases will now be published every 4 weeks, rather than every 6 weeks, to accelerate the delivery of new features to users. It is noted that the optimization of the release preparation process and the improvement of the testing system make it possible to generate releases more often without compromising quality. For enterprises and for those who need more time to update, once every 8 weeks, the Extended Stable edition will be released separately, which will allow you to switch to new functional releases not once every 4 weeks, but once every 8 weeks.

          This is to announce coreutils-9.0, a stable release.
          
          This is a new major release, with these significant changes:
            - cp has changed how it handles data
              - enables CoW by default (through FICLONE ioctl),
              - uses copy offload where available (through copy_file_range),
              - detects holes differently (though SEEK_HOLE)
              - This also applies to mv and install.
          
            - utilities are more tuned to the hardware available
              - wc uses avx2 instructions to count lines
              - cksum uses pclmul instructions for --algorithm=crc
          
            - More amalgamation of utilities
              - cksum now supports the -a option to select any digest.
              - This is the preferred interface, rather than sha*sum etc.
              - This is similar to the amalgamation of encoding utilities
                introduced in the basenc command in v8.31.
          See the NEWS below for more details.

        • GNU Coreutils 9.0: cp Now Enables CoW By Default + Copy Offload, wc Now Uses AVX2

          Coreutils 9.0 is now available and it’s a significant update to this collection of common open-source utilities found on effectively all Linux systems.

          First up, the widely-used cp utility for copying files/directories has some notable changes. With Coreutils 9.0, cp now enables copy-on-write (CoW) support by default using the FICLONE ioctl. Additionally, cp now uses copy-offload where possible by means of the copy_file_range system call. The cp command also now detects holes differently, among other changes. These cp changes also apply to the mv and install utilities too.

        • C++ String to double Conversion

          in C++, you will not end up with 49.12. In fact, the compiler should issue an error message. To have the result, 49.12, “14.25” has to be converted to a number type of double or float, and “34.87” has to be converted to a number type of double or float.

          The title of this tutorial is “C++ String to Double Conversion”. Is your aim to convert string to double; or to do all of the following, which are related?

        • C++ string append

          The word “append” means to add something at the back of another thing. A string can be declared in C++ in two main ways. Declaring a string as an array-of-chars or as a constant-pointer-to-chars is one way. Instantiating a string object data structure from the string class is another way. To instantiate a string object from the string class, the C++ string library has to be included in the program.

        • C++ String trim Methods

          C++ does not have a function to trim a string. There is a subject in computer programming called, Regular Expressions, abbreviated regex. This subject has schemes, which enable the programmer to search for a sub-string in a target string and replace the sub-string found. The sub-string found can be replaced with nothing, and so erasing it.

          The search-and-replace with nothing idea can be used to trim a string. So look for all white space characters in front of the string and all white-space characters behind the string, and replace them with nothing. Luckily, C++ has a regex library, which has to be included in the program to do this.

        • C++ String Replace

          C++ String Replace deals with locating a particular sub-string in a target string and then replacing it. A string can be created in two main ways: using a constant character pointer (char array) or instantiating it from the string class. The string class has a replace() member function. This does the locating and replacement. Locating and replacing is done with instantiated string objects and not strings created using a constant character pointer.

          The string object is a data structure, and its main component is a list. Each cell of this list has a character. The total sequence of characters forms the literal string. Each character position can be accessed by an index or by an iterator. Index counting begins from zero. An iterator is an elaborated pointer.

          The C+ string class has different variants of the replace() member function. Such a set of functions are called overloaded functions. This article explains how to use different overloaded string replace() member functions.

        • Pandas to check cell value is NaN

          The main documentation of the pandas is saying null values are missing values. We can denote the missing or null values as NaN in the pandas as most developers do. The NaN and None keywords are both used by developers to show the missing values in the dataframe. The best thing in the pandas is that it treats both NaN and None similarly. To check the missing value of a cell, pandas.notnull will return False in both cases of NaN and None if the cell has NaN or None.

          So, in this article, we will explore different methods to check whether a particular cell value is null or not (NaN or None).

        Luckily, technology can come to the rescue in the form of this handy open-source automatic guitar tuner by [Guyrandy Jean-Gilles]. The tuner has a Raspberry Pi Pico inside, with a microphone attached to the ADC. The program running on the Pico listens for the sound of a plucked string and determines whether the note is sharp or flat. The Pico then drives a small DC gear motor in the appropriate direction, which turns the peg the right way to bring the string into tune. The tuner makes ample use of 3D-printed parts, STLs for which are included in the project repo. [Guyrandy] has also made some updates to the project to make the tuner a little easier to use.

          Central to this issue are Across Lite .puz files, a format which hasn’t been upgraded in twenty years. Despite being aged and proprietary, an entire community of solvers, developers and checkers has sprung up around the availability of puz files, making them a de-facto standard. Not only are puz files used to distribute daily crosswords, the NYT maintains an archive of all its crosswords in puz format going back to 1993, even before online puzzles were introduced. There are various newer formats floating around, but with the entrenchment of the puz format none has emerged as a clear winner. The Across Lite team even developed a new format at the request of NYT in back 2015, but strangely, the NYT has never used it.

          [...]

          Based on the information made available so far, several things don’t make sense to many in the community. Why the sudden notice, and not a transition period to give the community time to make an orderly transition to this new “something”? Why is the archive of puz files being removed, given that the problem is with preparing puz formatted files, not maintaining them? Almost overnight, scripts have popped up to convert the NYT website crossword into puz format, and similar scripts have been around for some time. This begs the question, just how difficult is it to prepare puz files? And other than printing your puzzle on paper, this announcement ends the ability to solve puzzles offline, such as when you’re flying.

          Many third-party puzzle app and program developers have reached out to Ms. Mason asking that she reconsider.

            Are you a student who is studying data security in college? Are you looking for ideas for your research paper about Linux cybersecurity? You’ve come to the right place. In this article, we will talk about five current topics for a research paper on Linux cybersecurity, as well as how to approach each of them. Being a student who wants to pursue academic success is not something unnatural.

            However, along this journey, there could be many setbacks and obstacles to overcome. But these challenges will help you become better at this topic, especially because it is of high importance. As technology evolves even more, new software products, apps, websites appear.

            And so, it is increasing the possibility of a hacker attack, identity theft, and many other cyberattacks that can happen online. So, discussing Linux security in your research paper is essential, and here are five current topics.

          • This Week in Security: Somebody’s Watching, Microsoft + Linux, DDoS

            Last week we talked about the simple-to-exploit vulnerability in the Open Management Infrastructure, commonly installed on Linux VMs hosted in the Azure cloud. Botnets are already scanning the internet for vulnerable machines, and installing malware. The primary payload seems to be a Mirai variant, which among other things closes the vulnerable ports upon infection. Even though your VM doesn’t currently expose OMI to the internet, it may already be compromised. According to Caddo Security, there still haven’t been any automatic updates pushed to fix vulnerable servers, so unless a VM was manually updated last week, it should probably be assumed to be compromised at this point if it has OMI installed. This has the potential to be quite a big problem.

      • Hong Kong’s uncertain tech future

        Previously an entrepôt for western technology firms, the city-state is being bound ever closer to the economy of mainland China.

        Every morning the planes from Hong Kong touch down at London Heathrow, quickly disgorging their complement of passengers into the arrivals hall before refuelling their spent engines. Clutching British National (Overseas) passports, the line of travellers that begins to snake from border control is a testament to a new and sudden migration from this former colony to former colonizer. For almost all of these people, an uncertain future in the UK is preferable to the growing sense of political repression in Hong Kong.

        Almost 65,000 Hong Kongers have applied to settle in the UK this year, out of an eligible 5.4 million people. As a result, the city’s labour pool is beginning to dry up. “Go to schools and they’re saying they’re losing students because of immigration,” says Charles Mok, a former legislator for Hong Kong’s IT sector and now director of the think tank Tech for Good Asia. Recent figures suggest the city’s population has dropped by 1.2% in just one year. “That exodus of talent is huge, and it’s difficult for companies. Many of them are losing their employees in many sectors, including IT, including banking.”

      • Facebook Oversight Board’s Palestine decision: right direction, not enough

        The Facebook Oversight Board’s latest decision on the platforms’s unjustified removal of news content related to the recent bout of violence in Palestine and Israel is welcomed, but not enough.

        “The details of the Oversight Board’s first MENA case affirms, once again, that Facebook’s arbitrary and non-transparent decisions are a feature, not a bug,” said Marwa Fatafta, MENA Policy Manager at Access Now. “We support the Board’s decision on this occasion, but demand accountability, transparency, and assurance that blatant censorship and disrespect for a people, a language, and a complex social context will never put us in this situation again.”

        On May 10, 2021, a Facebook user in Egypt shared a news item from news platform, Al Jazeera, which contained a threat of violence by a Qassam Brigades spokesperson. Facebook initially removed the content after being reviewed by two content moderators for violating its Community Standard on Dangerous People and Organizations. Although Facebook restored the content, this is emblematic of Facebook’s systematic overenforcement of this Community Standard, particularly in relation to Arab and Muslim communities.

    • Monopolies

      • Microsoft is heading for a new antitrust showdown

        In July 2021, the UK government invited startups, businesses, and policymakers to a consultation about the most pressing competition problems in the tech industry, ahead of the launch of its new Digital Market Unit (DMU). One person familiar with the discussions says that something odd was happening behind closed doors. In private discussions entrepreneurs claimed Microsoft was behaving in a way they thought was detrimental to healthy competition; yet none dared to publicly call Microsoft out in the consultation.

        Most startups complained about Microsoft’s tendency to “bundle” new features in its products that directly competed with the startups’ core creations. But the source says startup founders were too scared of Microsoft’s reaction to go public with their gripes. The founder of an enterprise software startup said that Microsoft would “absolutely kill” their business if they spoke out, the source claims– implying that they feared the tech giant would make their products incompatible with Microsoft’s software ecosystem.

        The DMU consultation is slated to conclude on October 1 – whether any British startup will publicly denounce Microsoft is anyone’s guess.

        The episode is indicative of an ongoing shift. While Microsoft has been largely absent from heated discussions about Big Tech’s anticompetitive practices for nearly a decade, new entrants are increasingly worried – if not necessarily vocal – about the company’s dominance in both the enterprise software and cloud domains. Regulators in the UK and Europe might soon start taking notice of that, too.

        In the past, Microsoft’s tendency to bundle its software products – such as browsers and media players – together in a way that was considered damaging to competition was slapped down by the EU with multimillionaire fines. But since 2014, under the stewardship of CEO Satya Nadella, Microsoft has managed to pull off two great pivots. First, it swore off a software licence model in favour of Office 365’s cloud-based subscription-based model. Then it restyled itself as a tranquil benevolent actor, a far cry from both the second-wave tech giants routinely on the front pages of newspapers for data gluttony and fake news, and Microsoft’s own cutthroat reputation of yore. But several companies, especially in the less headline-grabbing b2b sector where Microsoft is king, think that it has not really changed.

      • Patents

        • Unitary Patent and Unified Patent Court – finally happening? [Ed: More fake news from Team UPC, hoping that by lying to people they can make something impossible and illegal magically come about (also, they pay the Web sites to help spread lies)]

          The project to establish a Unitary Patent in Europe and a Unified Patent Court to handle patent infringement litigation for European patents is underway again. After several years’ further delay due to constitutional challenges in Germany, progress towards setting up this project, 40 years in the making, is again resuming. The Preparatory Committee expects the Court to open for cases in mid-2022.

        • ZTE reportedly goes on the offense, sues unnamed Chinese smartphone maker over 4G standard-essential patents: possibly Tinno or Transsion?

          The Wechat platform may be an unusual place for patent litigation information to leak, but that’s what just happened. According to this Chinese article, Chinese smartphone maker ZTE has brought a 4G standard-essential patent (SEP) case against a fellow Chinese device maker in Shenzhen. The defendant has not been announced yet–and according to the article may not even have been served yet.

          Rumor (on the same webpage) has it that ZTE is suing a company with a small market share in China but a much larger one abroad. If true, that would rule out companies like Huawei, Xiaomi, Oppo, Vivo, and OnePlus. The more likely targets would then be Tinno Mobile, which is known as a contract manufacturer (Original Device Manufacturer, “OD”M) but also owns a French device maker named Wiko, or Transsion, which is huge in Africa and has a presence in South Asia. Transsion’s brands include Tecno, Itel, and Infinix.

          A recent ruling by the Supreme People’s Court (SPC) of the People’s Republic of China” laid out the criteria for Chinese jurisdictions over a global SEP dispute. At a conference hosted by Renmin University of China, IP-specialized judges discussed that case in a wider context. While it weighs in favor of Chinese jurisdiction over a worldwide FRAND matter if the implementer generates a high percentage of its worldwide sales in China, it is not an absolute requirement as other factors, particularly where products are developed and manufactured, are also considered in the Chinese judiciary’s very case-specific and fact-intensive decisions.

        • Vizio sued for TV display patent infringement

          According to Reuters, Maxell has alleged that Vizio infringed on a patent that includes the ability to display content from certain sources via USB, wireless adapters or digital broadcast signals. The case also accuses Vizio of infringing on a patent around the upscaling of images and image-processing technology.

          The company acquired the patents from Hitachi in 2009, and licences them along with other patents to consumer electronics brands.

          The complaint goes on to claim that Vizio had been aware of the patent portfolio since 2013 when it entered an agreement with Hitachi while being aware that two of its suppliers have licensed Maxell’s patents.
