Late in 2021, Xmonad released a new major version (0.17) of both 'xmonad' and 'xmonad-contrib'. These new versions include a bunch of new and cool features, like the ability to have your terminal swallow windows. But 0.17 didn't land in Arch Linux until recently, so I'm just now getting to explore these new features.
Looks like the "journalists" got a little bit too excited and reported on a fake data breach incident. As of today TikTok has not had a data breach containing 2 billion peoples records, but its only a matter of time until a real breach comes.
While it's certainly past its prime, IRC is still alive and kicking today. Here are some of the best open-source and free IRC clients for Linux.
Despite being overshadowed by other forms of social media, there are people who still use IRC. It's been one of the most resilient forms of conversation in the history of online communication, and while it's certainly past its prime, IRC is still alive and kicking today. It's so alive that dozens of clients are still being actively developed.
Here are some of the best Linux IRC clients to choose from today.
Linux desktops has a lot of utilities to view disk usage. These utilities gives us information on what programs or files uses large chunk of our disk space. Here we will show you some of the best apps for you to view disk usage in Linux.
[...]
Disk usage analyzer or Baobab is a GUI tool comes preinstalled with many popular Linux distributions. If you are using Gnome desktop environment, then Baobab is already preinstalled in your system.
In addition to local disk usage, disk usage analyzer can also view remote disks mounted in your system. You can see the disk usage in a very intuitive spherical graph.
[...]
The most popular option to work with disks in Linux is gnome-disk-utility. You can use this to not only view all the disks, but also format, change filesystems and make encrypted disks.
Alternatively, you can also view disks connected with your device using the file manager application. Open your file manager and click on the other location tab at the bottom to see all the disks connected with your device.
Thinkorswim was launched in 1999 as an options brokerage platform. However, later it was acquired by TD Ameritrade, although Thinkorswim’s brokerage services were shut down, the trading platform is still active and distributed by TD Ameritrade for its clients. Besides the trading feature, Thinkorswim users also have access to trading and analysis tools, online courses, etc.
Unlike TradingView which can be linked to the trading accounts of many different brokers, Thinkorswim is only used by TD Ameritrade clients.
Thinkorswim allows users to freely set alerts based on parameters of technical indicators and price movements. Meanwhile, TradingView allows users to receive only 12 different alert conditions. However
In this post, you will learn how to install LibreCad on Ubuntu 22.04 | Linux Mint 21.

With LibreCAD you can do many designs and all with a robust, open-source platform.
Recently I’ve been working on a project where I implement a bunch of tiny toy working versions of computer networking protocols in Python without using any libraries, as a way to explain how computer networking works.
I’m still working on writing up that project, but today I wanted to talk about how to do the very first step: sending network packets in Python.
In this post we’re going to send a SYN packet (the first packet in a TCP connection) from a tiny Python program, and get a reply from example.com. All the code from this post is in this gist.
Most of what we do happens from within a web browser. However, that doesn't mean we want every single page we use to run as yet another tab. If you're like me, those tabs can add up. And if you're not using a browser with a solid tab management feature (such as Opera's Workspaces - which is the best tab manager, hands down), those tabs can very quickly become overwhelming.
This resulotion is 1920*x , the scaling seems very small for me with 12 inch. So I decided to adjust it. I was using libinput drivers for the trackpad. But It was horrible for thinkpad trackpad. So I decided to move back to synaptics.

Consul is an open-source multi-networking tool that offers a fully-featured service mesh solution that solves the networking and security challenges of operating microservices and cloud infrastructure (multi-cloud and hybrid cloud).
Consul manages services and nodes in the form of a “directory service”, i.e. in the form of what runs where? Access is via DNS or HTTP(s). Consul operates in either Server or Agent mode. The servers store the data, if several are used, the data is automatically synchronized.
The data can be accessed directly on the servers via DNS or HTTP(s) or via the required agent anyway. Any node or host logs on to Consul via the agent and is registered as a node. Services can also be registered. A web server, for example, registers as a new cluster member to an existing service. In addition, tags can also be set, which then display themselves as aliases via DNS query.
Convert2RHEL is a Red Hat utility that converts operating systems that are similar to or derived from Red Hat Enterprise Linux (RHEL), such as CentOS Linux and Oracle Linux.

In this tutorial, we will show you how to install Opera Browser on Fedora 36. For those of you who didn’t know, Opera is one of the most popular and widely used web browsers globally, developed by Opera Software. The browser is based on Chromium but distinguishes itself from other Chromium-based browsers through its user interface and other features such as battery-saving and built-in VPN.
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 the step-by-step installation of the Opera Browser on a Fedora 36.
Many people that use VirtualBox, at some point come across a problem they have not encountered before.
In this article, I want to cover as many issues that may arise and how to fix them. This may be hum drum to some, but I’m sure there may be some tidbits in here that can be useful. The first part of the article is more basic than the second part.
How many Linux servers do you administer? Chances are pretty good you’re working with considerably more servers running the open-source operating system than ever before. That can be a time-consuming task when you have to SSH into each server and run your daily admin tasks.
Rocky Linux has quickly become a darling of the open source industry, poised to help users and admins alike totally forget that CentOS ever lived on their servers and data centers. Rocky Linux is as fine a server OS as you’ll ever use and has all but been guaranteed that it will never go away.
But, like all operating systems, you’re going to need to upgrade. Why? Security patches, bug fixes and new features. I realize many admins are hesitant to migrate their production servers from one release to another and that’s an understandable proposition. After all, everything is working to perfection, so why would you want to risk it? As with any operating system, with major updates come major features.
I've been using Borg backup for a couple of years and it has seemingly worked very well for me. One difference I really appreciate from my previous arrangement (rdiff-backup) is the freedom to move large files or file hierarchies around (including between different filesystems) without provoking large backup incrementals.
In this tutorial, we will show you how to install NVM on Ubuntu 22.04 LTS. For those of you who didn’t know, NVM is a Node Version Manager tool. Using the NVM utility, you can install multiple node.js versions on a single system. Its works on any POSIX-compliant shell (sh, dash, ksh, zsh, bash), in particular on these platforms Linux, macOS, and Windows WSL.

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 the step-by-step installation of the NVM (Node Version Manager) on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.
Linux-PAM is a rich collection of shared modules that interactively authenticate a user to programs (or services) in a Linux system. Linux-PAM is an acronym for Pluggable Authentication Modules, which developed from the Unix-PAM design. It combines numerous low-level authentication modules with a high-level API to provide dynamic authentication for apps. Despite the underlying authentication scheme, this enables developers to create applications that require authentication. Linux-PAM (also known as “PAM”) is frequently supported by default in contemporary Linux variants.
The most crucial thing for a system administrator to understand is how PAM configuration files provide the link between services and PAMs that carry out the actual authentication activities. You don’t need to comprehend PAM’s inner workings. PAM could significantly alter your Linux system’s security. Incorrect settings may fully or partially prohibit access to your machine.
This simple tutorial shows how to install the latest LXQt desktop 1.1.0 in (L)Ubuntu 22.04 via its official PPA.
The light LXQt desktop environment has reached version 1.1.0 for a few months, which LUbuntu 22.04 ships the 0.17 version by default.
Git is the most popular version control system. Many developers and teams use Git for their activities. One common practice when working with Git is to create branches that help create a separate working environment. With branches, you can mess around with things without affecting the other sections of the code, and at long last, you can compare your branches and then merge them. The question is, “how do you compare two branches using Git?”
Malcolm is an open-source network traffic analysis tool that uses a framework of tools to create a robust analysis tool for network admins. Malcolm accepts network traffic data in the form of PCAP (full packet capture) files and Zeek logs.
I myself did great research on this topic of Linux games and came to you for fulfilling your thirst for a generic list of games for Linux in August 2022.
Arriving a month after KDE Plasma 5.25.4, the KDE Plasma 5.25.5 point release is here to address more significant bugs and regressions, such as the major regression in multi-monitor support for the Plasma Wayland session that could cause screens to not display the output.
Also in the Plasma Wayland session, KDE Plasma 5.25.5 fixes a KWin crash that occurred when dragging an attachment from the Mozilla Thunderbird email client and improves support for some apps like the GIMP image editor to no longer fail to appear in the Task Manager when it’s opened.
Time for another development report from the YaST Team including, as usual, much more than only YaST.
[...]
Over the last year or so, we got some reports about the graphical interface of YaST presenting rendering issues, specially on HiDPI displays and on openQA. The reporters provided screenshots that showed how some widgets were apparently drawn on top of the previous ones without an intermediate cleanup, so the screen ended up displaying a mixture of old and new widgets that were very hard to read.
We were unable to reproduce the problem and we tried to involve people from different areas (like graphic drivers maintainers, virtualization experts or X11 developers) to track the problem down with no luck… until now! We finally found where the bug was hiding and hunted it down.
See the pull request that fixes the issue if you are interested in a technical description including faulty HiDPI detection, unexpected Qt behavior and QSS style sheets oddities. It also includes a screenshot of the described (and now fixed) problem.
Recently we have had a run on Bring Your Own Subscription (BYOS) topics in the cloud, here is another.
Fedora is where day-to-day development and innovation happens. Fedora Linux releases every 6 months and each release is maintained for about 13 months. Major changes should be (and almost always are) deployed in Fedora first, following the Change process. Fedora packages sources are maintained in dist-git and built in Fedora Koji.
At the beginning of the development cycle of a new CentOS major release (meaning, 9, 10, etc.), Fedora is branched into the new distribution. Historically, this is done from the current stable Fedora release at the branching time (e.g. Fedora 34 for CentOS Stream 9). After the distribution is branched, the development cycle for the new CentOS Stream release begins.
Nowawadys, Fedora ELN helps prepare for the branching process by continuously rebuilding Rawhide (the development version of Fedora). This provides a view into what a new CentOS Stream could look like if it were branched from Fedora today, and ensures that the spec file logic stays compatible with the future set of EL macros and build flags at any given point in time.
My previous post in this series tracked what I had done until the 5th week, and gave some information on the technical aspects of the project. This post covers the work done since.

The KCM didn’t actually work like a KCM because changing a permission on the interface would instantly change the permission in the overrides file as well, instead of sending it to a “waiting” area until the user hits “Apply” button. Similarly, the “Default” and “Reset” buttons did nothing.
Most KCMs use a KConfig file, instead of an overrides file like being used here, to store the settings. This caused me to stall for a while since I wasn’t sure how to proceed, but after my mentors referred me to the tablets KCM, work picked up again and I proceeded to implementing the 3 buttons.
Now because I was not there so my understanding and knowledge would be disadvantageously asymmetrical to Guido and others who were there and could talk and share more. Having a Debian mobile or Debian on the mobile could also make Debian more popular and connectable to the masses, one of the things that were not pointed out in the Debian India BOF sadly. At the same time, there are some facts that are not on the table and hence not thought about.

FWIW, while I do have GNOME and do use a couple of tools from the GNOME stack, I hate GNOME with a passion. I have been a mate user for almost a decade now and really love the simplicity that mate has vis-a-vis GNOME. And with each release, MATE has only become better. So, it would be nice if we can have MATE on the mobile phone. How ‘adaptive’ the apps might be on the smaller area, I dunno. It would be interesting to find out if and how people are looking at debugging memory leaks on mobile phones. Although finding memory leaks on any platform is good, finding them and fixing them on a mobile phone is pretty much critical as most phones have fixed & relatively small amounts of memory and it is and can get quickly exhausted.
One of the things that were asked in the Q&A was about payments. The interesting thing is both UK and India are the same or markedly similar in regard as far as contactless payments being concerned. What most Indians have or use is basically UPI which is basically backed by your bank. Unlike in some other countries where you have a selection of wallets and even temporary/permanent virtual accounts whereby you can minimize your risks in case your mobile gets stolen or something, here we don’t have that. There are three digital wallets that I know – Paytm – Not used (have heard it’s creepy, but don’t really know), Google pay (Unfortunately, this is the one I use, they bought multiple features, and in the last couple of years have really taken the game away from Paytm but also creepy.). The last one is Samsung Pay (haven’t really used it as their find my phone app. always crashes, dunno how it is supposed to work.) But I do find that the apps. are vulnerable. Every day there is some or other news of fraud happening. Previously, only States like Bihar and Jharkhand used to be infamous for cybercrime as a hub, but now even States like Andhra Pradesh have joined and surpassed them :(. People have lost lakhs and crores, this is just a few days back. Some more info. on UPI can be found here and GitHub has a few implementation examples that anybody could look at and run away with it.
Ah, the impending smell of autumn. The crunch of leaves, the smell of pumpkin spice everything… and a new release of Ubuntu. ‘Tis the season for the .10 release of Canonical’s flagship operating system, and this time around, the name is Kinetic Kudu. On Sept. 29, 2022, the new release will be available to the masses, and although it doesn’t offer up a single feature that will blow anyone away, it does have a few nice tricks up its sleeve that are sure to please longtime fans.
The latest point release of the Ubuntu 20.04 LTS distribution is now available and sports kernel 5.15.
As you might expect, there’s another point release available for the LTS version of Ubuntu. Although this update doesn’t include much in the way of new features, it does offer plenty of bug fixes, security patches, app updates, and kernel 5.15.
If you’re already using Ubuntu 20.04, you can get the .5 release by way of the built-in upgrade system, which means there’s no need to do a fresh install.
One thing to keep in mind is that 20.04 is not the latest LTS release for Canonical’s flagship operating system. That title would belong to 22.04. However, since there are still a large number of users still working with 20.04 (and since it is still supported until April 2025), Canonical continues to push upgrades.
The Arduino IoT Cloud enables makers, IoT enthusiasts and professionals to build easily connected projects based on a wide range of Arduino, ESP32 and ESP8266 boards.

For developers, there is no debate. The future of the database is open source. A glance at the 2022 Stack Overflow survey of around 70,000 code-wranglers shows nearly all pros use one of the two leading open source RDBMSes, PostgreSQL (46.5 percent) or MySQL (45.7 percent), although they use other systems as well.
Oracle, which built a global software empire starting with an RDBMS, is only used by about 12 percent of developers, while Db2, the IBM data workhorse used by banks and global retailers, is only used by 2 percent.
There is no question that the leading edge is open source – the people who build new systems are making it so by their choice. The question is why they are achieving dominance among devs.
Peter Zaitsev, CEO of database consultancy Percona, was an early employee of MySQL AB under the leadership of original open source database author Michael "Monty" Widenius. To Zaitsev, it is a question of economics in the startup scene of the early Noughties.
"If you look at Oracle and Db2, they can be very, very expensive systems. In the early 2000s, just after the dotcom era, the new generation of startups, starved of capital, needed but could not afford Oracle, Db2 or SQL Server," he says.
One of the bugs that we see in computer programs including LibreOffice is the crash. You’re working with the application, and suddenly the program is suddenly closed! Here we discuss the usual causes for these crashes, and how to fix some of them.

We propose a design for a privacy-friendly method of age restriction in e-commerce that is aligned with the principle of subsidiarity. The design is presented as an extension of a privacy-friendly payment protocol with a zero-knowledge scheme that cryprographically augments coins for this purpose. Our scheme enables buyers to prove to be of sufficient age for a particular transaction without disclosing it. Our modification preserves the privacy and security properties of the payment system such as the anonymity of minors as buyers as well as unlinkability of transactions. We show how our scheme can be instantiated with ECDSA as well with a variant of EdDSA, respectively, and how it can be integrated with the GNU Taler payment system. We provide formal proofs and implementation of our proposal. Key performance measurements for various CPU architectures and implementations are presented.
For my GSoC project, I wanted to find the intersecting point of two arbitrary bezier curves. There are some existing algorithms for this purpose, but since it can be interesting, I decided to try to find one algorithm myself. I did some not successful research on finding it, here’s the story and what I learned.
The bezier curves in Krita are 2 variable cubic equations, so naturally, I thought of finding the intersecting point by solving the equations of the two curves. I wrote down the equation, type them into Wolfram Mathematica and hoped MMA to give me a result. There must be some performance regression between MMA 11 and MMA 13. The MMA 13 I’m using stuck there and never gave any result. I had to ask my friend who’s still on MMA 11 to calculate it.
Yes, though I have more or less thought that the general solution of the equation would be complicated, however, when I saw my friend sending me a 1.1M picture of the result, I knew the actual result was way wilder than I expected. (You may view this picture on a new page to see how big it is.)

I take a bike ride every morning, it’s a nice way to think about topics of the day. I’ve been wondering lately why software supply chain security has exploded in popularity in the last year or so. Nothing happens by accident, so there must be some series of events we can point at that has led to everyone suddenly making this a priority. Software supply chain security is not new, I’ve been doing it since about 2002 when I was helping track and coordinate security vulnerabilities in Linux distributions. We didn’t call it a supply chain back then, and nobody really paid attention to it. So what changed between then and now?
CISA has released five Industrial Control Systems (ICS) advisories on September 06, 2022. These advisories provide timely information about current security issues, vulnerabilities, and exploits surrounding ICS.
CISA, the Federal Bureau of Investigation (FBI), and the Multi-State Information Sharing and Analysis Center (MS-ISAC) have released a joint Cybersecurity Advisory (CSA), #StopRansomware: Vice Society, to disseminate tactics, techniques, and procedures (TTPs) and indicators of compromise (IOCs) associated with Vice Society actors identified through FBI investigations as recently as September 2022.
Early in the coronavirus pandemic, health officials closely monitored sewage samples for signs of the virus to track where it could be circulating. Now, that technique is being used to detect other infectious diseases: polio and monkeypox.
While the Turkish military is trying with great effort to monitor the Medya Defense Zones and in this way make guerrilla units the target of air and ground attacks, the guerrillas are systematically destroying and dismantling the cameras.
The Supreme Court (SC) heard the People’s Union of Civil Liberties’ (PUCL) Application seeking directions to ensure that authorities do not prosecute individuals under S.66A of the Information Technology Act, 2000 (IT Act, 2000), considering the SC has struck down S.66A as unconstitutional in Shreya Singhal v Union of India & Ors., (2015) 5 SCC 1. Since the last date of hearing, 12 High Courts, 10 States and 1 Union Territory (UT) replied to the Application and several of them admitted that S. 66A cases were still pending in their jurisdiction. Today, after hearing submissions from counsels, SC directed Advocate Zoheb Hossain, the counsel for the Union of India, to write to States where S.66A cases are pending, on behalf of the Supreme Court of India, and impress upon them the need to take remedial measures. Senior Advocate Sanjay Parikh represented PUCL and IFF provided legal assistance.
Unfortunately, I'll have to start this month's newsletter with sad news. The co-creator of Let's Encrypt, Peter Eckersley, lost his battle with cancer at the age of 43. He was also the director of computer science at the Electronic Frontier Foundation and has worked on Certbot, Privacy Badger, HTTPS Everywhere and many other privacy-related projects. RIP, Peter.
This is a community of writers, I can tell. While I would like to say that I am a writer as well, admittedly, I write a lot faster than most. I started writing when I started roleplaying, and I've gotten in the habit of quickly writing things down then eagerly awaiting responses. That can be alright, in an environment such as that, but here everyone types elegantly and verbosely, and I feel a bit out of place. I can write detailed and powerful, but I just don't always do that, always aiming for a weird combination of humor and seriousness when writing.
To answer your question impulse, I think you should write whatever you feel like writing, be it short or long.
I get your apprehension though. I definitely felt overwhelmed by all the technical posts here initially. I know considerably less than most people on here about programming and general tech stuff, so I felt a bit out of place when it came to the drivel I personally felt like writing.
