In this video, I am going to show an overview of AlmaLinux OS 8.5 and some of the applications pre-installed.
In this episode of Linux Essentials, we'll go over data streams. Specifically, Standard Output (stdout), Standard Input (stdin), and Standard Error (stderr). We'll also take a look at how to redirect specific data streams, so you can easily separate errors from output.
DevOps has changed the way many technology organizations work, by making the administrator the center of the development cycle (rather than an outside resource). In this episode, Jay and Joao discuss DevOps and how it's changed the landscape.
Going back two years already ASpeed developers have been working on prepping AST2600 support for Linux, their seventh generation server management processor / BMC. The latest open-source driver activity points to the AST2600 having DisplayPort support.
The AST2600 is the successor to the widely-used AST2500. The AST2600 makes its claim of being the world's first BMC SoC on a 28nm process and is powered by a dual-core Arm Cortex A7.
The Linux kernel continues to see improvements around ASUS laptop support on Linux, but the contributions have not been coming directly from the company but rather the community and sometimes after reverse-engineering.
The ASUS-WMI driver has seen a great deal of work recently in the Linux kernel for improving the device support particularly with the higher-end ASUS laptops. There has been dGPU toggling, panel overdrive, platform profile support, and more. Much of this work has come thanks to Linux kernel developer Luke Jones.
IWD as the Intel-developed iNet Wireless Daemon that can serve as a replacement to the likes of WPA_Supplicant while integrating nicely with NetworkManager / systemd-networkd / ConnMan is out with a new version.

The second 5.16 kernel prepatch is out for testing. "Nothing especially noteworthy stands out for the last week, it all felt pretty normal for a rc2 week".
Last year with Intel "Tiger Lake" was the introduction of Control-Flow Enforcement Technology (CET) for helping fend off return/jump-oriented attacks and as part of CET is hardware Indirect Branch Tracking (IBT) support. There have been patch series working to implement CET's IBT support but after having gone through 30 rounds of review and not being merged, a new take on it was submitted today.
For months there has been work on supporting Intel Control-Flow Enforcement Technology's Indirect Branch Tracking feature in the Linux kernel. The most recent revision of that I am aware of is the v30 patches sent out last August. But those patches were never merged nor even any Linux kernel mailing list comments to that revision.
AT&T was dropped from Multics. This led to the invention and implementation of the Unix OS in 1969. Unix was created by American Computer Science legends Kenneth Lane Thompson and Dennis MacAlistair Ritchie of AT&T Bell Labs. And the first version was released in 1970.
2 years later they created C out of UNIX. And there comes the future base of many programming languages! C added portability and availability to UNIX and thus it became increasingly popular, widely adopted, modified, and copied by businesses and academic institutions across the globe. AT&T was the sole owner of the UNIX copyrights.
American Programmer Richard Matthew Stallman began the GNU project to create a free UNIX-like operating system in 1983. He wrote GPL (GNU General Public License) as a part of his project. By the 1990s, there was enough software to build a complete operating system. However, Hurd, the GNU kernel couldn’t pull enough development work leaving GNU incomplete.
In 1987, American-Dutch Professor Andrew S. Tanenbaum wrote UNIX-like system MINIX for academic use. The source code of MINIX was made available for everyone, however, MINIX couldn’t be either modified or redistributed. MINIX’s 16-bit architecture wasn’t well adapted to Intel’s increasingly popular 386 design for PCs. It became highly expensive for private users to use UNIX for Intel 386 personal computers.
And this led to Linus Torvalds’ beginning of a new project. Later Linus Torvalds stated that if either 386BSD or GNU Hurd was available during his time, he wouldn’t be interested in writing his project.
As alert folks of a cross-platform inclination will have noticed, Paragon's NTFS driver was accepted into the Linux kernel, and was released as part of 5.15.
This has had a consequence they probably didn't consider, though: you can now boot Linux from an NTFS partition.
But wait, there's more. Since a Linux installation doesn't use any of the same file or folder names in the root directory, you can even install them into the same partition as Windows.
So far, the primary application of this horrifying hack is probably the entertainment to be obtained from reading the stricken comments on Github. However, the fà âtid fertile imaginations of some of the commenters raised some valid reasons why. For example, if you have a company policy that forbids you from repartitioning your machine, you could obey the letter if not the spirit of the law and dual-boot this way.
Microsoft's latest work in the area of open-source graphics drivers with the Mesa stack is for adding Direct3D 12 video acceleration support.
As part of Microsoft's continued work around supporting GUI applications with Windows Subsystem for Linux (WSL2) and mapping Vulkan/OpenGL/OpenCL over Direct3D on Windows, Microsoft engineers are now working on adding Direct3D 12 video acceleration support to Mesa.
Pinta 1.7.1 is intended as the final update in the GTK2-based series, with a GTK3 build (dubbed Pinta 1.8) said to be nearly ready for release.

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 VLC Media Player on an AlmaLinux 8. You can follow the same instructions for CentOS and Rocky Linux.
NAT or Network Address Translation allows multiple computers on a private network to share a common IP to access the Internet. One set of IP addresses is used inside the organization and the other set is used by it to present itself to the internet. This helps in conserving limited public IP space. At the same time, it also provides security by hiding the internal network from direct access from the outside world.
This tutorial explains how to remove malware from WordPress sites. After reading this article, you will know how to detect malicious codes in your site and how to remove them.
Using the GREP command has been used widely among the Linux and Unix-like operating systems. It can find syntaxes, specific text, and many more inside a pile of codes or strings. Using the GREP command is not always worthy of finding specific values or of filtering some data-set from a file system or repository. The main use case of the Ack command in Linux gets highlighted when we need to run some repository-level commands for searching values and running queries.
In Linux, you can easily use the GREP command on the terminal shell. You might be surprised to know that many power Linux users have already been using the Ack command to replace the GREP command. However, both GREP and Ack command function to output the same type of results, but they have their own individual pros and cons.
pgAdmin is a free and open-source graphical administration tool for PostgreSQL, one of the most advanced open-source databases. pgAdmin is a feature-rich PostgreSQL administration tool with a simple interface and easy to use. It supports PostgreSQL 9.6 and above, and it can be run on multiple operating systems, including Windows, macOS, and Linux.
Today’s digital world heavily relies on file compression, and ZIP is one of the best applications to do this job efficiently. If you are planning to transfer your data to another device or if you are planning to email multiple files, then the ZIP utility can combine and compress that data to reduce the size, allowing them to deliver at quicker speeds. You can also UNZIP a zipped file, the data in it will remain in its original format. For instance, if you have received a ZIP file as an email attachment then how can you extract the data of that file in Linux Mint? This is where UNZIP comes in handy and you can use this utility to extract the data without any data loss. So, in this article, you will learn how you can compress a ZIP file and later UNZIP it on Linux Mint.
If you’ve been following terminal-focused installation instructions for Linux applications for a while, you’ve probably come across the curl command at some point or another. cURL is a command-line tool for transferring data with URLs. One of the simplest uses is to download a file via the command line. This is deceptive, however, as cURL is an incredibly powerful tool that can do much more.
Dropbox provides cloud service to the users by using which they can not only manage their data by storing it on the cloud but also can share data with others by uploading it on the drive. An account on dropbox can be accessed through the browser. It also supports the application which can be installed on any operating system including the distributions of Linux.

In this guide we are going to learn how to install MongoDB 5.0 Community Edition on an Debian 11 server.
MongoDB is a cross-platform document-oriented NoSQL database program that uses JSON-like documents with optional schemas. MongoDB is developed by MongoDB Inc. and licensed under the Server Side Public License.
MongoDB was built for people building internet and business applications who need to evolve quickly and scale elegantly. Companies and development teams of all sizes use MongoDB for a wide variety of reasons.
Instead of storing data in tables of rows or columns like SQL databases, each record in a MongoDB database is a document described in BSON, a binary representation of the data. Applications can then retrieve this information in a JSON format.
In this tutorial guide, we are going to learn how to install and use Docker-ce on Fedora 35.
Docker is a set of platform as a service product that uses OS-level virtualization to deliver software in packages called containers. Containers are usually isolated from one another and bundled their own software libraries and configuration files, they can communicate with each other through well-defined channels.
Docker makes it possible to get more apps running on the same old servers and also makes it easy to package and ship programs.
In this post, you will learn the Cortex installation process.
In this guide we are going to learn how to install MongoDB 5.0 Community Edition on a FreeBSD 13 server.

Have you ever been caught up in a situation when the network services on your Manjaro Linux system stopped, and you were unable to connect to a server or a network? You would be amazed to know that, in a few seconds, you can solve these kinds of issues by restarting the network services.
On Linux-based systems such as Manjaro, network services are a series of background applications that play their part in some specific events such as building a connection to the internet, moving files, and so on. In terms of computer networking, a network service is an application that operates on the network application layer and above; it also offers various valuable options such as data manipulation, storage, communication, and presentation.
If you are facing any network issue or in case you have made changes in the network configuration files, then being a Manjaro user, you should restart the networking services for the changes to take effect. This write-up will demonstrate how to restart Network Services on Manjaro Linux using NetworkManager and Systemd-networkd. So, let’s start!
In this modern computing era, web browsers play a vital role in a computer user’s life. These tools act as a medium between a user and the internet. There are tens of browsers that are serving such as, Google Chrome, Firefox, Safari, Opera, Microsoft Edge, and so on. Several browsers have marked their place in trending slots, like Firefox, Safari, but Google Chrome outperforms all these.
Google Chrome provides cross-platform support that also strengthens its user’s support, as various operating system users can avail it on their machine. The frequent updating mechanism of Google Chrome also distinguishes it from other browsers. In this piece of writing, we will provide the possible ways to update google chrome on Manjaro Linux.
Manjaro is an Arch-based distribution of Linux and is equipped with all the basic features that a Linux distro has. Manjaro has extensive support to get packages either from its official repository or from AUR (Arch User Repository). The update of packages is recommended to carry out, as they bring new features, security patches, and bug fixes.
The package manager is the key stakeholder in updating the packages of a Linux-based system. Like other distributions, Manjaro also uses a package manager named “Pacman“. The “Pacman” is used for all Arch-based distributions of Linux.
Following the importance of the package update, we will demonstrate the possible ways to get packages updated on Manjaro Linux.
The fast and reliable architecture of MySQL enhances its popularity among its competitors such as PostgreSQL. MySQL is a database management system that is used in the back-end of the website to store and manage the data of the website.
MySQL is an RDMS that uses SQL as a query language, for this reason, most functions and clauses used in SQL can be executed in MySQL but it is not compulsory that every SQL query can be used in MySQL. The same is the case with a SELECT TOP clause which is used in SQL to display the top rows or to perform different operations on them and is not supported by MySQL. In this write-up, we will discuss what the SELECT TOP clause is? What happens if we use the SELECT TOP clause in MySQL? And What is the alternative of SELECT TOP in MySQL?
Do you want to run minimal Ubuntu 20.04 Cloud Image on VirtualBox? Then here is a simple and quick tutorial to do that…
Ubuntu 20.04 LTS is the popular server and desktop Linux operating system, however, the standard image of it is around 1GB or more, which would not be a cup of tea forever body. Especially those who want to run Ubuntu to test some Linux server applications but without investing much hardware resources.
Earlier there was minimal ISO image available by Ubuntu developers, however not after 18.04. Therefore, we have another option that is a cloud Image, available to use by cloud platforms. But we can use the same on VirtualBox and here are the simple steps to do that.
Logs are beneficial to collect information. They can be beneficial while troubleshooting an issue. Logs can also be a pain to deal with but they also are lifesavers while troubleshooting an issue. In this article we will Install and configure logrotate on CentOS 8.
The digital workplace relies heavily on file compression, and this is where ZIP files come in handy. They keep all of your data and files in one location and function similarly to normal folders on your computer. However, the contents of zipped files are compressed, reducing the amount of data needed by your computer that reduces the file size, making it easier to transmit or keep.
So you’re looking at a ZIP file if the extension .ZIP or.zip appears at the end of the file name. In addition, the file’s icon would be changed. Suppose that if you have various audio files in the format of .mp3, then after making a zip file, those files will change their format to the .ZIP, and their icon will also change. After receiving a ZIP file, the recipient can unzip (or extract) it and utilize it in its original format.
RAR is a short form of the Roshal Archive that you can use to organize multiple folders, documents, photos, and other data. However, what distinguishes a RAR file is that it takes special software to access its contents. It’s one of the most used methods for compressing data and supports both archiving and compression, so you may store numerous files within a single RAR file.
Furthermore, RAR files can be encrypted and password-protected, which ensures that the contents of these files remain hidden until the password is known. In addition, a RAR file might be helpful if a colleague has a long list of images they want to share with you. Your buddy could aggregate all the photos into one RAR file and then send you that file, rather than having you download them individually. This guide can help unravel any doubts you may have regarding how to make and open a RAR file if you already didn’t know.
KDiskMark is a free and open source graphical benchmarking utility that can be used to measure performance of storage drives. It can determine read and write speed estimates with good accuracy for both hard drives and solid state drives. It can run benchmarks on external drives connected to your Linux system as well.
In Linux, groups are the entities used for the organization and management of numerous user accounts simultaneously. Groups offer easy and quick administration of user accounts. Various Linux users have many different task assignments and roles. The key point of groups is the identification of a set of rights like write, read or execute access for a specified resource that can be mutually shared among the group users.
In this guide, we will discuss how many types of groups exist in the Ubuntu Linux system. Moreover, we will also elaborate on how to add a Ubuntu user into the groups.
In plain words, if we have multiple Linux computers in a network then to identify each of them using a custom name, we can generate hostnames, custom names generated by the user. Well, while setting up any OS, the hostname is usually set by it automatically depending upon the system. However, there are many scenarios where we need to set the one manually to easily identify the system over a network so that there will not be any kind of conflict relating to the hostname.
Here we will learn a few easy methods to change the hostname on the popular Ubuntu 20.04 LTS focal fossa server or desktop OS.
In menu "Filesystem -> Easy Version Control", I took a snapshot, and wondered why it was so big. I then chose to rollback to "pristine first bootup" and ticked the checkbox to save browser settings -- that's when I discovered what is wrong -- the firefox cache is 1.1GB and that gets saved.
So, it is not really a "pristine first bootup" if it is keeping the firefox cache.
What initially seemed like a really promising idea, to give you gaming on any device and wherever you are has turned into something of a let-down overall.
This will no doubt get me some flak from Stadia stans, but let's keep in mind I was originally totally sold on the idea of Stadia. I have a Founders pack and I used it almost daily for quite some time. That time quickly lessened, and eventually became none at all. I can't imagine I am alone in that either.
At the two year point, what did Google do to celebrate Stadia? Close to nothing. On Reddit the Stadia team went over some numbers we already knew like the amount of games available and a few that added special Stadia features.
While the actual single-player campaign of Wolfenstein: Enemy Territory never officially happened, a modder has now released their attempt to bring it back with Wolfenstein: Enemy Territory Single-Player.
Originally the official game was going to be an expansion to Return to Castle Wolfenstein and a standalone game, however it was cancelled and then released as a free to play online game, that lives on as ET: Legacy. At least now we can see some of what it might have become! This mod takes the online maps and sticks them together, to turn them all into a connected single-player and co-op campaign.
Sanitarium, the popular point-and-click horror from 1998 is getting a fresh life thanks to the ScummVM project (announcement). An effort that is over 10 years in the making, the next major release of ScummVM will have support for it out of the box.
"Sanitarium features a plot intricate set in an intense dark world where a very thin line separates senses from madness. There are many riddles to solve throughout this immersive and captivating adventure that will make your head spin with terror.
Even now, Sanitarium is a masterwork suitable for point-and-click beginners, confirmed or riddle-solving experts who enjoy."
Valve have released the latest big update to the Steam client, after a good while of Beta versions bringing with it some major new features - especially on the Linux side. If you are opted into the Steam Client Beta, you will have already seen and probably used a bunch of what's new but this is for everyone sticking with the main client.
For fans of the Steam Play Proton compatibility layer, it's the big one that brings with it support for CEG DRM, making many more games playable that weren't previously. However, that currently needs you to use Proton Experimental, at least until Proton 6.3-8 rolls out (currently in testing).
Ready for your next adventure? Looks like Humble Bundle has a reasonably nice set of games available in the Choose Wisely Bundle live now. Only two of the included games have a native Linux build, so as usual we shall let you know what to expect with Steam Play Proton for the others.
Punk Wars is combat-heavy turn-based 4x strategy game from Strategy Forge S.A. and Jujubee S.A. and it's out now.
"Punk Wars is a combat and tactics-oriented strategy drawing inspiration from the classic turn-based 4X titles. Set in a post-apocalyptic world, in which the ruins of a once powerful megacity become the arena for a deadly fight between four newly emerged corporations, trying to assert dominance for both their unique technology and philosophy of life.
[...]
Punk Wars is available on Steam. The Linux version is not on the GOG store.
Creative Assembly look to really be going all-out for Total War: WARHAMMER III, with so many mechanics getting big improvements and recently they talked about battles with a new video.
These are primarily quality of life improvements, aimed to making battles feel a little better to engage in overall so don't go expecting anything too game-changing. Still, there's a huge amount of tweaks that will be coming with it. Some of it includes a toggle to get flying units off the ground, idle unit hotkeys, better formation options taken from Three Kingdoms, new "lazy" health bars to indicate incoming damage, a full unit browser page, healing is now a percantage of max health per-second rather than a flat value and much more.
Linux is among the most well-known and easily accessible open-source operating systems. Because of its stability, portability, and customization, Linux has recently earned much attention and is now extensively being utilized. One of them is the desktop environment feature, which is mostly used for Linux-based operating systems, and Xfce is one of them.
Xfce was originally stated as XForms Common Environment, an open-source desktop environment designed explicitly for Linux. It aspires to be quick and light while remaining aesthetically beautiful and simple to use. Because of its small size, it saves both memory and CPU, making it suited for older hosts with limited desktop resources. On the other hand, Xfce is versatile and powerful enough to meet system requirements as a power user. It offers a very reliable, feature-rich, and straightforward experience. This article will cover the top 5 distros for XFCE which we think you consider for your desktop environment experience.
A new overview effect makes it easier for users to interact with both Plasma Activities and Virtual Desktops.
KDE Plasma is a very user-friendly desktop interface found on several popular Linux distributions. But there are a couple of features that have needed some slight tweaking for a while. Those features are how users interact with both activities and virtual desktops.
With the release of KDE Plasma 5.24, that all changes as both features are getting a rather GNOME-like makeover. A new overview screen will offer a full-screen view of both virtual desktops and all currently open applications. Along with these two features, a search bar will be included with the overview that allows users to find applications, files, browser tabs, documents, and more.
Although this might require longtime users to have to adjust their workflows, if the implementation is as successful as what GNOME did with version 40, most will be quite happy with how efficient it is.
A new beta build of CutefishOS is available to download.
While things aren’t quite “daily driver” ready (yet) the distro provides a quick and easy way to try the latest developments in the Qt-based Cutefish desktop environment on top of a familiar apt foundation. We looked at an Ubuntu-based offshoot a few months back.
MX Linux 21 “Wildflower” was officially released last month on October 21st as a systemd-free distribution based on the latest and greatest Debian GNU/Linux 11 “Bullseye” operating system series. The new release is available with the Xfce, KDE Plasma, and Fluxbox editions.
Since it’s based on Debian GNU/Linux 11, MX Linux 21 is powered by the Linux 5.10 LTS kernel by default, but the developers made a special version for those who need to run MX Linux on their hardware with a newer kernel version, namely Linux kernel 5.14.
The primary goal of the project was to extend posix_spawn(3) to include chdir(2) for the newly created child process. Two functions were supposed to be implemented, namely posix_spawn_file_actions_addchdir() and posix_spawn_file_actions_addfchdir(), to support both chdir(2) and fchdir(2) respectively. posix_spawn() is a POSIX standard method responsible for creating and executing new child processes.
“The team at STFC were looking for a vendor-backed solution to help manage its Kubernetes estate. Working with SUSE Rancher, the Kubernetes architecture was easy to deploy, manage and scale.” Sheng Liang, President of Engineering and Innovation, SUSE.
Some here might not know it, but some teams from the 'SUSE Quality Engineering Linux Systems Group' use the Redmine installation here at https://progress.opensuse.org/ to track the results of the test automation for openSUSE products. Especially openQA feature requests are tracked and coordinated here.
As the plain Redmine installation does not provide all wanted features, we included the "Redmine Agile plugin" from RedmineUP since a while now. Luckily the free version of the plugin already provided nearly 90% of the requested additional features. So everybody was happy and we could run this service without problems. But today, we got some money to buy the PRO version of the plugin - which we happily did :-)
This article will demonstrate how to configure Fedora Server as an alert and notification server that can place calls using an Asterisk PBX and send SMS text messages using Twilio. The use of the SMS message feature is optional. By using the call_only endpoint of the caller_prometheus_webhook component, you can limit the alerts to voice calls only.
Please consider that interacting with the Asterisk PBX is not easy. But it isn’t too hard either. If this is your first time working with this kind of application, coming to understand the concepts may require some patience. Fortunately, Fedora Server can be configured with Ansible and the installation of the py-phone-caller containers will not be difficult.

All Things Open 2021 wrapped up about a month ago, and as I look back two things stand out.
First, overall things went well and the outcome was a good one.
I have a tendency to initially focus only on what didn’t go as planned, but I often look back later and realize that the imperfections were far more insignificant than I originally thought, and the outcome far better.
With 30 days now to review the 2021 event, the same pattern holds true this year. Yes, not everything went as planned, but it never does. On the whole, attendees, speakers, and partners genuinely seemed to enjoy themselves and get value from the experience in a variety of ways. I’d call that a success.
I think contributing to LibreOffice is both fun and sometimes challenging. When ‘fun’ and ‘challenge’ come together, it creates a great community, as LibreOffice does; and being a part of this community makes you more passionate and stronger. And that’s why I wanted to become a TDF member.
When one thinks of business or government computing, Windows and Microsoft Office are typically the de-facto go-to. But that's not the case anymore for the German state of Schleswig-Holstein, which is planning on converting its public sector machines to the Linux and Libre side of the force by 2026.
This shift will involve around 25,000 PCs in total, as reported by the Document Foundation (additional figures can be found in Schleswig-Holstein's plan documentation [via Heise]). The idea behind the change is that free and open-source software should be given priority. A benefit from moving to Linux and Libre is forecasted to be saving money on licensing costs, though there are expense complications to be considered in terms of the migration itself and the costs of operational infrastructure when conducting state business through Linux and other open-source software.
The Application Delivery Technical Advisory Group of the Cloud Native Computing Foundation (CNCF) recently announced version 1.0 of the OpenGitOps specification.
The group has worked to define the core principles of GitOps, with the goal of formalizing the ideas that have developed around GitOps into “a single cohesive set of principles that would be easily digestible and repeatable by any organization.”
I’ve created a couple of minisites for key OS components, built using no frameworks, but plain CSS. Just having CSS grid and variables made it viable for me to avoid using frameworks recently. Having includes/imports one wouldn’t even need Jekyll.
There is a standard input-output stream header file used within the C++ language. This stream header has been used to get the input from the user and output it on the shell screen using the cin and cout statement within the code. The Standard “cin” statement will be used to get the standard input from the user at run time. The user enters some input and it will be saved to some variable. So, within this guide, we will be discussing the use of std::cin within the C++ code. So, make sure you have a g++ compiler configured within your Ubuntu 20.04 system.

As we all know, Python provides different built-in functions for creating, reading, and writing text files. Python handles two types of files. The first one is normal text files and the second one is binary files (which are written in a binary language or the form of 0s and 1s). In the text file, lines are closed with a special character (\n) known as EOL. It stands for End of Line. On the other hand, a binary file does not contain any line terminator and the data is stored after changing it into machine comprehensible binary language.
In this article, our focus point is to write strings to a file in Python. To write a string to a Python file, we first call the write() function on the text file object and then pass the string as a parameter to this write() function. In this quick tutorial, you will learn how to create a text file using a string, replace the original string with the new string, and display a list of strings in the text file using the for loop.
A CSV is a (comma separated values) file in which data is in the form of a tabular. The extension of the CSV file is .csv. This csv file is mostly used in the data analytics. Apart from the data analytics, the CSV file also used in the e-commerce application because it’s very easy to handle in all different types of programming languages.
We can convert the CSV to different data structures like a list, a list of tuples and a list of dictionaries. We can also save the CSV without the header or with the header as a list, and for that we can use some machine learning libraries like Pandas.
You may have heard and used many string variables within the programming language while coding. The Python R string i.e. Raw string is used as a prefixed lateral to consider some special characters i.e. backslash as a normal character or literal string. Within this article, we will see how R string can be used with strings to perform this specific task within the Ubuntu 20.04 system.
Are you looking for a guide to using special variables in Bash? Get prepared! This article explains how and when to use special variables while working in Bash.
In one of the previous articles, you learned about Bash variables. Bash comes with special variable features as well. They are used to control the Bash script’s execution flow. You can read their values but you can’t assign values to them. This article will take you through the usages of 9 different special variables used in Bash. So, let’s explore today’s topic on special Bash variables.
The video’s title claims that the tomatoes were turned into rocket fuel, which is far beyond the actual results of the experiment. However, with some more advanced chemical processing, we could certainly see the fruit becoming a mite more flammable than it was. You’re probably better off just sticking to straight cotton though, for the best results. Video after the break.
Florida Republican Gov. Ron DeSantis on Thursday signed what he called "the strongest piece of legislation that's been enacted anywhere in the country" in opposition to coronavirus vaccination mandates on workers.
Flanked by Republican legislative leaders, DeSantis officially made Florida the first state with a law that imposes fines on businesses and hospitals that require inoculation against Covid-19 without exemptions or alternatives. DeSantis signed the legislative package into law a day after Republican lawmakers passed his anti-mandate agenda during a fast-moving special session that was largely divided along party lines.
As Americans prepare to hit the highways and airports this Thanksgiving holiday, CISA and the Federal Bureau of Investigation (FBI) are reminding critical infrastructure partners that malicious cyber actors aren’t making the same holiday plans as you. Recent history tells us that this could be a time when these persistent cyber actors halfway across the world are looking for ways—big and small—to disrupt the critical networks and systems belonging to organizations, businesses, and critical infrastructure.
There are actions that executives, leaders, and workers in any organization can take proactively to protect themselves against cyberattacks, including possible ransomware attacks, during the upcoming holiday season—a time during which offices are often closed, and employees are home with their friends and families. Although neither CISA nor the FBI currently have identified any specific threats, recent 2021 trends show malicious cyber actors launching serious and impactful ransomware attacks during holidays and weekends, including Independence Day and Mother’s Day weekends.
CloudLinux’s security platform for Linux-based websites and web servers contains a high-severity PHP deserialization bug.
A high-severity security vulnerability in CloudLinux’s Imunify360 cybersecurity platform could lead to arbitrary code execution and web-server takeover, according to researchers.
Security updates have been issued by Debian (firebird3.0, libmodbus, and salt), Fedora (js-jquery-ui and wordpress), Mageia (arpwatch, chromium-browser-stable, php, rust, and wireshark), openSUSE (barrier, firefox, hylafax+, opera, postgresql12, postgresql13, postgresql14, and tomcat), SUSE (ardana-ansible, ardana-monasca, crowbar-openstack, influxdb, kibana, openstack-cinder, openstack-ec2-api, openstack-heat-gbp, openstack-heat-templates, openstack-horizon-plugin-gbp-ui, openstack-keystone, openstack-neutron-gbp, openstack-nova, python-eventlet, rubygem-redcarpet, rubygem-puma, ardana-ansible, ardana-monasca, documentation-suse-openstack-cloud, openstack-ec2-api, openstack-heat-templates, python-Django, python-monasca-common, rubygem-redcarpet, rubygem-puma, firefox, kernel, postgresql, postgresql13, postgresql14, postgresql10, postgresql12, postgresql13, postgresql14, postgresql96, and samba), and Ubuntu (libreoffice).
I have long been annoyed that the word “crypto” has been co-opted by the blockchain people, and no longer refers to “cryptography.” I’m not the only one.
VirusTotal is an online portal, owned by Google, that uses many antivirus engines to check for viruses and malware. It provides an API service that Wazuh uses to scan file hashes, domain names, IP addresses, or URLs. For this integration we use the wazuh-integratord component that runs on the Wazuh manager. Check our VirusTotal documentation for more information about this integration.
In this use case, we monitor a directory in real time and do a VirusTotal scan to every new or recently modified file. If a file is classified as malicious, an active response is triggered and the file is removed.
Active response allows Wazuh to run commands on an agent in response to certain triggers. In this use case, we simulate an SSH Brute Force attack and configure an active response to block the IP of the attacker. So, in this post you will learn how blocking attacks with active response.
Weaknesses in e-commerce portals are being exploited to deploy a Linux backdoor as well as a credit card skimmer that's capable of stealing payment information from compromised websites.
"The attacker started with automated e-commerce attack probes, testing for dozens of weaknesses in common online store platforms," researchers from Sansec Threat Research said in an analysis. "After a day and a half, the attacker found a file upload vulnerability in one of the store's plugins." The name of the affected vendor was not revealed.
In February, the Modi government’s notification of Information Technology Rules was met with concern and criticism. There were demands for the withdrawal of the rules, primarily because of their negative impact on the right to privacy and freedom of expression and their overbroad scope. Several challenges against these rules are pending in various High Courts, and some of the interim orders issued indicate that these courts share concerns about the rules’ unconstitutionality.
There has also been a lack of clarity on how key aspects of the rules are to be complied with, including, for example, which platforms need to comply with the requirement to trace the “first originator” of content.
In early November, the government released “Frequently Asked Questions on Part-II of the IT Rules”, in an attempt to provide clarity and allay concerns. (Part II of the rules set out due diligence requirements, including traceability and establishes a grievance redressal mechanism. This part applies to intermediaries, and “significant social media intermediaries”, which are those with more than 50 lakh users).
However, it arguably fails to allay concerns, and the limited clarity they offer is on certain procedural aspects relating to the appointment of compliance officers. The questions otherwise rehash old defences, for instance with respect to traceability, that does not substantively address concerns raised by civil society, tech companies and internet users.
