    When it comes to running virtual machines on home Linux systems or for personal use most of us either go for VirtualBox or Vmware workstation player, however, there is more best option i.e KVM/Qemu. Qemu and KVM both are open source platforms for performing virtualization on Linux platforms. KVM stands for Kernel Virtual Machine, where QEMU is an emulator that can also be used as a virtualizer with the help of KVM to provide a native speed by accessing Intel VT-x or AMD V technology of modern processors.

    KVM is a virtualization module that can easily be installed in any Linux kernel to allow it to function as a type 2 hypervisor.

    Thus, the installation of KVM becomes a lot easier, we only need a Linux-based system such as Ubuntu and a processor with intel-v / VT-x or AMD-v support. All new processors have this instruction set extension. Only the small processors, such as the Atom from Intel, or very old processors may lack this feature.

  • How to Use Two-Factor Authentication with Ubuntu

    Over time, the traditional username and password authentication has proven inadequate in providing robust security to applications and systems. Usernames and passwords can easily be cracked using a plethora of hacking tools, leaving your system vulnerable to breaches. For this reason, any company or entity that takes security seriously needs to implement 2-Factor authentication.

    Colloquially known as MFA (Multi-Factor Authentication), 2-Factor authentication provides an extra layer of security that requires users to provides certain details such as codes, or OTP (One Time Password) before or after authenticating with the usual username and password.

    Nowadays multiple companies such as Google, Facebook, Twitter, and AWS, to mention a few provide users the choice of setting up MFA to further protect their accounts.

  • How to Run the Same Command Multiple Times in Linux – Linux Hint

    When programming, you may encounter a situation in which you need to perform the same task multiple times. A simple solution is to manually repeat the process as many times as it is needed; however, it is not productive to do so. That is why the concept of loops was introduced to programming. The basic goal of a loop is to repeat a task several times, depending upon the value provided for the iterator and the termination condition of the loop. Loops allow programmers to avoid the hassle of repeating processes manually.
    Suppose that there is a command that you wish to run multiple times. There are several important reasons that you might need to run a command repeatedly, so you want to be sure that a certain command produces the correct output every time it is executed. The more you run a command manually, the more certainty you will gain each time you run the command.

    But how do you do this programmatically? Well, there are several methods that can be used to run the same command multiple times, as well as for verifying the output of the repeated command. This article shows you how to create a repeatable command using Linux Mint 20 as the host operating system.

  • KenShape is a new tool to get easy 3D models from 2D pixel-art by Kenney | GamingOnLinux

    Want a quick way to make 3D models? Here's your fresh tip of the day for prototyping, game development or anything else - check out the new KenShape application from Kenney. For those unaware Kenney is the developer of games like Pixross, Frick, Inc., the Asset Forge application to bash together blocks to make 3D models and — oh, an absolute ton of high quality assets both paid and public domain.

    Their latest work is quite brilliant with KenShape. You draw something in a pixel-art block style, give it some depth based on numbers 1-8 with 1 being thin and 8 being quite large and it will then generate a proper 3D model of it. You can preview it first though of course but the result is quite remarkable. Generated models can be exported to various 3D formats compatible with most game engines (including Unity, Unreal Engine, Godot, Asset Forge, Blender and PlayCanvas), or as .vox files compatible with voxel software like MagicaVoxel.

  • Syslog-ng on BSDs

    My FOSDEM presentation in the BSD devroom showcased what is new in sudo and syslog-ng and explained how to install or compile these software yourself on FreeBSD. Not only am I a long time FreeBSD user (started with version 1.0 in 1994) I also work on keeping the syslog-ng port in FreeBSD up to date. But soon after my presentation I was asked what I knew about other BSDs. And – while I knew that all BSDs have syslog-ng in their ports system – I realized I had no idea about the shape of those ports.

    [...]

    In this blog I identified many problems related to syslog-ng in various BSD port systems. I also provided some workarounds, but of course these are not real solutions. I cannot promise anything, as I am not an active user or developer of any of these BSD systems and I am also short on time. However, I’m planning to fix as many of these problems at the best effort level, as time allows.

  • Lessons Learned From the SolarWinds Supply Chain Hack

    In a recent Linux Foundation blog post titled “Preventing Supply Chain Attacks like SolarWinds,” the foundation’s Director of Open Source Supply Chain Security, David A. Wheeler, adamantly pushed the need for software developers to embrace the LF’s security recommendations to prevent even worse assaults on government and corporate data security in the wake of the rampant data breach.

    Wheeler’s post is timely and filled with information to make it harder for hackers to exploit the future systems we all depend on. He includes 11 Linux Foundation recommendations including how organizations can harden their build environments against attackers, the need to begin shifting towards implementing and then requiring verified reproducible builds, and the practice of changing tools and interfaces so unintentional vulnerabilities are less likely.

    According to Wheeler, SolarWinds met some of the foundation’s defensive measures. None of them prevented the successful SolarWinds attack, he said. More software hardening is needed.

    The SolarWinds Orion software product is proprietary. So how can open-source coding methods help create better security?

  • M1 MacBook SSDs are facing a big problem — and it could kill your laptop

    The new M1 chip in Apple's latest MacBooks offers great performance and battery life. It may not be so good for your storage drive, however.

    On Twitter and several other forums, users of the latest MacBook Air, MacBook Pro and Mac Mini models are reporting solid-state-drive (SSD) wear rates far higher than expected. If the figures are accurate and the trend continues, it could mean worryingly short lifespans for Apple's latest batch of laptops.

    [...]

    In the case of the tested Macs seen in these threads, one Mac Mini user claimed to have written 165TB of data in just two months of use. Compared to equivalent retail SSDs from Toshiba (who supplies the SSDs inside the MacBooks), that's equivalent to 10% of its total warrantied TBW.

    In theory, the SSDs in Apple's M1 MacBooks should guarantee reliable use for around five years. But this rapid rate of use slashes that reliable life to less than two years.

    This 10% figure seems to be an outlier. Most users complaining about this issue are reporting figures of 2-3% usage, as seen on threads on the MacRumors forum and the LinusTechTips forum. That's still higher than you'd expect for a brand-new device, though.

  • Remap custom keyboard keys in Linux - Tutorial

    Modern problems require modern solutions. I've recently got meself a new Linux test laptop, one IdeaPad 3, which I bought (unfortunately, due to market shortages) with the UK keyboard layout instead of the US layout. This means suboptimal physical key placement - even if you do use a different keyboard variant. Namely, the bar and backspace keys and such are placed all wrong, plus the Enter key is too small.

    Moreover, this also means, muscle memory and all, you end up typing \ when you actually want to jump to a new line, and this can be quite annoying. So I thought, perhaps I can remap keyboard keys in a small way? But I didn't want to just remap the backspace key (bearing the UK tilde and hash symbols) to a "second" Enter, thus effectively making a larger Enter key, I still wanted to have the bar and backspace keys available. Hence a more complex exercise. Let me show you how you can this somewhat convoluted but super-nice setup.

  • Linux server certifications becoming a must-have for IT pros | Network World

    Linux certification is increasingly significant for tech workers as the public cloud and software-defined networking become ever more important. A Linux cert can set IT professionals apart from the herd and potentially put a lot more money in their bank accounts.

    Once these certifications were a gauge of reliability, according to CompTIA chief tech evangelist James Stanger. “Twenty years ago, Linux tended to attract people who were a little edgier,” he said. “So certification was traditionally used in the Linux side just to find people you can work with—will they show up on time?”

    Now, these certifications are a demonstration not only of proficiency but also dedication to self-improvement. “You can’t go wrong with a certification,” said Joe Faletra, director of infrastructure services at Modis, a technology staffing and consulting firm. “I’ll lean towards certs over experience [in hiring], because this person has put the effort into learning and passing the exam.”

I know there are 254 usable host addresses available with a broadcast address of 192.168.1.255, a gateway/router address of 192.168.1.1 or 192.168.1.254 (depending on who's running the network), and a human-readable netmask of 255.255.255.0. That's my standard network. After all, 254 hosts are enough for any subnet, right? Wrong. A few years back, I had to step outside of my standard 254 hosts per subnet scenario when I decided to use a 22-bit netmask (255.255.252.0) to get a 1022 usable address space.

    I knew little about this address space, and it was frustrating to try to search for the simple information that I needed without scrolling through forums with all the idle chatter and off-topic rhetoric. I guess some people just need a space in which to air their grievances about everything. I digress.

  • How To Install XFCE Desktop on Ubuntu 20.04 LTS - idroot

    In this tutorial, we will show you how to install XFCE Desktop on Ubuntu 20.04 LTS. For those of you who didn’t know, XFCE is one of the most popular desktop environments for Linux desktop. XFCE is a free lightweight, fast, and easy to use software desktop environment for Unix/Linux-like operating systems. It is designed for productivity and aims to be fast and low on system resources. Unlike GNOME and KDE desktops which are heavier, but XFCE uses fewer system resources. Furthermore, it offers better modularity and fewer dependencies to install and takes less time and low disk space on your hard drive.

    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 XFCE lightweight desktop environment on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian based distribution like Linux Mint.

  • How to read column data from a text file in a bash shell script

    One common task in day-to-day shell scripting jobs is to read data line by line from a file, parse the data, and process it. The input file can be either a regular text file (e.g., logs or config files) where each line contains multiple fields separated by space, or a CSV file that is formatted with delimiter-separated values in each row. In bash, you can easily read columns from a file and store them into separate variables for further processing. In this tutorial, let me demonstrate with examples how you can write a shell script that reads columns into variables in bash.

  • David Tomaschik: Is Reusing an Old Mac Mini Worth It?

    The last version of Mac OS that was supported is Mac OS X 10.7 “Lion”, which has been unsupported since 2014. Since I’m a Linux guy anyway, I figured I’d see about installing Linux on this. Unfortunately, according to the Debian wiki, this device won’t boot from USB, and I don’t have any blank optical media to burn to. This was the first point where I nearly decided this wasn’t worth my time, but I decided to push on.

    Linux is pretty good about booting on any hardware, even if it’s not the hardware you installed on, as kernel module drivers are loaded based on present hardware. I decided to try installing to a disk and then swapping disks and seeing if the Mac Mini would boot. The EFI on the Mac Mini supports BIOS emulation, and that seemed the more likely to work out of the box.

    I plugged a spare SSD into my SATA dock and then used a virtual machine with a raw disk to install Debian testing on the SSD. I then used the excellent iFixIt teardown and my iFixit toolkit to open the Mac Mini and swap out the drive. I point to the teardown because opening a Mac Mini is neither obvious nor trivial.

    [...]

    During all of these tests, I had the Mac Mini plugged into a Kill-A-Watt Meter to measure the power consumption. Idling, it’s around 20 watts. Under one of these load tests, it reaches about 45-49 watts. Given that the Raspberry Pi 4B only uses around 5W under full load, the Pi 4B absolutely destroys this Mac Mini in performance-per-watt. (Note, again, this is an old Mac Mini – it’s no surprise that it’s not an even comparison.)

    [...]

    Given the lack of expandability, the mediocre baseline performance, and the very poor performance per watt, I can’t see using this for much, if anything. Running it 24/7 for a home server doesn’t offer much over a Raspberry Pi 4B, and the I/O is only slightly better. At this point, it’s probably headed for the electronics recycling center.

  • How to get started with FUZIX on Raspberry Pi Pico

    FUZIX is an old-school Unix clone that was initially written for the 8-bit Zilog Z80 processor and released by Alan Cox in 2014. At one time one of the most active Linux developers, Cox stepped back from kernel development in 2013. While the initial announcement has been lost in the mists because he made it on the now defunct Google+, Cox jokingly recommended the system for those longing for the good old days when all the source code still fitted on a single floppy disk.

    [...]

    Since then FUZIX has been ported to other architectures such as 6502, 68000, and the MSP430. Earlier in the week David Given — who wrote both the MSP430 and ESP8266 ports — went ahead and ported it to Raspberry Pi Pico and RP2040.

    So you can now run Unix on a $4 microcontroller.

  • How To Install The Default GNOME Shell Theme (Adwaita) On Ubuntu 20.04, 20.10 And 21.04 - Linux Uprising Blog

    This article explains how to install the default GNOME Shell theme, Adwaita, on Ubuntu 20.04, 20.10 and 21.04 (hint: it's trickier than you would think).

    The GNOME Shell theme is the theme used for the top panel, activities overview, system dialog and notifications. GNOME uses Adwaita as its default theme for both GTK and GNOME Shell.

    You may want to use the default GNOME Shell theme not only because you don't like Yaru GNOME Shell theme, or you're a fan of Adwaita, but also because you may want to test things using the default GNOME Shell theme (this is why I needed this actually).

    Ubuntu ships with Yaru as the default GTK and GNOME Shell theme. While Adwaita GTK theme comes preinstalled on Ubuntu, the Adwaita GNOME Shell theme is trickier to install, even though you actually already have it, but it doesn't show up in GNOME Tweaks / can't be used by default.

  • A guide to Python virtual environments with virtualenvwrapper

    For some time, Python has included support for managing virtual environments. Python 3.3 even added the built-in venv module for creating environments without third-party libraries. Python programmers use several different tools to manage their environments, and the one I use is called virtualenvwrapper.

    Virtual environments are a way of separating your Python project and its dependencies from your system-installed Python. If you use a macOS or Linux-based operating system, it very likely comes with a version of Python as part of the installation, and in fact, it will probably be dependent on that particular version of Python to function properly. But it's your computer, and you may want to use it for your own purposes. You may need to install another version of Python than the operating system provides. You may need to install some additional libraries, too. Although it's possible to upgrade your system Python, it's not recommended. It's also possible to install other libraries, but you must take care not to interfere with anything the system relies on.

  • Killing frozen applications in Ubuntu 20.0

    At times, in a computer system when applications are running the system might freeze and does not respond. This seems annoying since users are not even able to close the program by using the X icon on the UI of the application. This is because the processes/applications are not responding and they will not simply be closed by the UI method. Even continuous rebooting of your system does not seem to be a suitable solution. Sometimes, users have many critical data that could be unsaved. There are solutions to such problems that are easily adaptable and will cover them in this article.

    In Ubuntu, there are many methods used to kill such frozen applications in which users are not required to reboot their systems. xkill, and system monitor utility are the famous methods used along with kill, pkill, and killall commands. In this article, I will show you 3 different ways of killing frozen applications on an Ubuntu 20.04 system using GUI as well as the command line.

  • Check Your Disk Usage Using ‘duf’ Terminal Tool [Friendly Alternative to du and df commands]

    Before I knew about this utility, I preferred using a GUI program like Stacer or the pre-installed GNOME Disk usage app to check free disk space and the disk usage numbers for my system.

    However, duf seems to be a useful terminal tool to check disk usage and free space that is written in Golang. Even though Abhishek suggested me to give this a try, I found it more interesting, especially considering that I’m currently learning Golang, what a coincidence!

    It is fairly easy to use no matter whether you are a terminal guru or just a beginner not comfortable with the terminal. It is certainly easier to understand than the df command for checking disk space utilization.

    Let me highlight some of the key features and its usage before you get it installed on your system.

  • Linux 101: What is the SUID permission? - TechRepublic

    If you're new to Linux administration, you've probably already started learning about file permissions. If I said "drwxrwxr-x," you'd know what that meant. It's simple: A directory with owner and group read, write, execute permissions, but only read and execute permissions for everyone else.

    That's not the be-all, end all for permissions. There are actually three more permissions, one of which I'm going to teach you about right now. Said permission is called SUID, which stands for Set owner User ID. This is a special permission that applies to scripts or applications. If the SUID bit is set, when the command is run, it's effective UID becomes that of the owner of the file, instead of the user running it.

  • What is the Vim Editor in linux?

    If you are working in the command line mode, you may need to become familiar with a text editor that will be operating in a Linux console. The vim editor is the original editor that Unix uses. It makes use of the console graphics mode for the emulation of a text-editing window, which allows you to see different lines of the file, move around across the files, and edit, insert or replace a piece of text. The vim editor works well with the data that is in a memory buffer. You have to type vim and the name of the file that you have to edit to open the editor with the desired file.

    If the editor is started without a filename being supplied, it opens but with no file. The vim editor detects the session’s terminal type and uses full-screen mode so the console window can use the editor area. The initial window will show the file contents and a message line at the bottom of the window. If the contents don’t take up the entire screen, a tilde is placed on the lines excluded from the file. The vim editor has two operational modes — normal and INSERT mode. When you open a file for editing, vim goes into normal mode, and certain keystrokes are interpreted as commands.

  • Keeping platforms open

    My previous article, Whatsapp and the domestication of users, got more attention than I was expecting. Some responses gave me a lot to think about,1 especially regarding actions we can take. I suggest reading that article first; it explained what “user domestication” is and why it’s a problem. It enumerated three countermeasures: FOSS, simplicity, and open platforms.

    Hard problems, by definition, lack easy solutions. Simply choosing (or creating) a platform that avoids user domestication isn’t enough if that platform can change. The price of freedom is eternal vigilance; in addition to settling on the right platform, we must ensure that it honors its users in both the present and the future. Keeping a platform FOSS and simple is more straightforward2 than keeping a platform “open”.

    How do we keep an open platform from becoming a closed platform in the future?

  • 6 Top Data Analysis Tools for Big Data

    Big Data is an all-inclusive term that refers to data sets so large and complex that they need to be processed by specially designed hardware and software tools. The data sets are typically of the order of tera or exabytes in size. These data sets are created from a diverse range of sources: sensors that gather climate information, publicly available information such as magazines, newspapers, articles. Other examples where big data is generated include purchase transaction records, web logs, medical records, military surveillance, video and image archives, and large-scale e-commerce. There is a heightened interest in Big Data and Big Data analysis and the implications they have for businesses. Big Data analysis is the process of examining huge quantities of data to find patterns, correlations, and other useful information that can help firms become more responsive to change, and to make better informed decisions. Big Data analysis can be performed with data mining software. However, the unstructured data sources used for big data analysis are not necessarily suitable for investigation by traditional data mining software.

  • How to use Django Serializers – Linux Hint

    Serializer is used in Django to convert the model instances or querysets into python supported data types that can be easily rendered into JSON, XML, or other formats. The deserialization can also be done by serializers to get back the original data from the serialized data. This feature is available in Django REST Framework. So, the users have to install this framework to use the serializers. Any webpage of the website may contain HTML, CSS, and data from the database tables. But the API does not understand these types of content, and it can understand the raw data only, that is, JSON data. How the serializers can be used to convert the model instance into JSON format has shown in this tutorial.

The main function of the queryset is to iterate the records of database tables by converting them into SQL queries. It can be used from the python command line or by writing the python script to display the browser’s output. The uses of queryset for retrieving data from a database table in different ways have been explained in this tutorial.

  • How often should I rotate my ssh keys?

    My story for today is about ssh and how even public keys, while much better than simple passwords, are still not a perfect solution.

    The danger is credential theft, which is a fancy way of saying “someone stole your private keys.” Back in the 1990s, that problem was pretty far from our minds; Windows 98 didn’t even have the concept of a separate administrator account, never mind the idea of app sandboxing or the inkling that someone might intentionally want to load malware onto your computer and encrypt all your files for ransomware. Those were the days when some people thought ActiveX controls (essentially loading .exe files from web sites) might be a good idea. Actually, maybe even a great idea as long as there was an “are you sure?” dialog box first.

Ubuntu Leftovers

    New restrictions will be in place beginning with Ubuntu 20.04.3 LTS this summer to try to enforce better quality releases with less regressions by enforcing better quality control. The change beginning with Ubuntu 20.04.3 LTS will require that stable release update (SRU) procedures are followed even for release blockers. This will require that every fix follows the same verification, regression analysis, and aging period process. The tighter quality controls will likely lead to slips in release targets if bugs are found in the release candidates for new point releases, as it will first need to go through the verification and aging process.
