=> ↺ Neovim vs Vim Comparison 2023 – Which is a better Editor? – DekiSoft

• If you are looking for a powerful terminal-based emulator for a long time then Vim is your go-to software. It is deemed to be one of the oldest open-source projects. We have many good terminal editors such as Nano but they don’t lie close to Vim in terms of functions, modes and extensibility. However, a much better player is in town now so we have put together a Neovim vs Vim detailed comparison along with Emacs and VSCode to see the differences so you can make an informed decision.

• This was until 2014 when Vim fork the Neovim had made its appearance on the open-source horizon. Although it came forward with many controversies still is hailed as the future which was designed keeping in mind the modern user. A lot of development was seen in both of these, especially after the development of Neovim over the years.

• Here’s our verdict captured in a legendary LinuxLinks ratings chart. We only feature free and open source software here.

Instructionals/Technical

=> ↺ GIMP Tutorial: Using The Heal Tool

• I still watch tutorials to learn new skills, and came across this one on Davies Media Design’s YouTube channel about the Heal tool.

• The Heal tool is similar to the Clone tool, but uses a bit different algorithm. While the Clone tool copies the exact pixels selected, and paints them over your chosen area, the Heal tool seems to take the surrounding pixels and imperfections into account as well, making your subject easier to paint (they are, after all, both brushes).

• Let’s look at the difference between the Clone tool and the Heal tool. If you have the tools grouped in GIMP, they are in the same group. If not, the Clone tool icon looks like a stamp, and the Heal tool looks like two bandages in an X-shape.

=> ↺ PDF Part 3A: Manipulating PDF Files, GUI Style

• My original plans were to have a three part article series that covered the creation of PDF files, the editing of PDF files, and finally, the manipulation of PDF files. But when I looked closer, I discovered there are several GUI programs that help with manipulating PDF files, and even more command-line programs for manipulating PDF files. So, I’ve decided to break the third article down into two related articles. This article, “PDF Part 3A,” will deal with the GUI programs you can use to manipulate the structure and orientation of a PDF file. The next article, “PDF Part 3B,” will focus on the command-line tools for manipulating PDF files.

• Some may argue that editing and manipulating PDF files are the same thing. But, that’s not necessarily so. Editing the contents of a PDF file changes the information conveyed in the PDF, while merely changing the page order or page orientation of a PDF file does not inherently change the contents of the file, nor the information conveyed. It’s a gray area, but we need to “draw a line” and make a distinction somewhere.

=> ↺ 5 Ways to Follow Symbolic Links in Linux

• Symbolic links (also referred to as “soft links” or “symlinks”) are a kind of shortcut to another file used in the Linux operating system mostly for shared libraries.

• If you’ve been using Linux as a regular desktop, you might already have encountered one or will in the future. But today’s focus will be on how you can find the original file to which the symbolic link points.

• Note that we already wrote a separate article for all the tools that are mentioned in this article, so this is kind of a summarized version of all the tools.

• However, if you directly jump to this article and are only interested in knowing a tool that can help you find the original file to which the symbolic link points, then you can directly read our readlink command article.

=> ↺ MicroK8s and Portainer: The Easiest Way to Deploy an App on Kubernetes – The New Stack

• Anyone who’s attempted to work with Kubernetes for the first time understands how complicated it is. Not only is creating a Kubernetes cluster a challenge but so too is deploying applications. With so many moving parts, this technology can get the best of anyone who doesn’t have a deep understanding of how it works.

• There are, however, shortcuts to take. One such shortcut is deploying Portainer to a MicroK8s cluster. I’ve already demonstrated how this is one in an earlier tutorial. Why would you go this route?

=> ↺ How to Only List the Files and Not the Directories in Linux

• In Linux, we use the “ls” command to navigate through directories for files. Listing all the files and folders in Linux is a common command. But occasionally, we must only list the files and not the folders. In that case, this command does not work. To only list the files using the “ls” command, we need to write “ls *.txt”. But this command works if we need to only list the text files since this command only lists the text files. If we need to list all the files and not only the text files, this command becomes useless. For that purpose, Linux provides us with many options. To list all the files in a specific directory only, we use the following methods:

=> ↺ How To Make Calendar with LibreOffice Calc

=> ↺ How to Enable Snap Support in Linux Mint

• Linux Mint doesn’t ship with snapd by default, and that’s an improvement over the Ubuntu base for many users. But what if you fancy snaps and want to install them on Linux Mint?

• Maybe you want to bring back the ease of installation and portability snaps bring to the table. Or perhaps, you need to install software that’s only available from the Snap Store.

• Whatever the reason is, enabling Snap support on Linux mint is quite easy.

=> ↺ Linux du Command: Common Examples

• The du command is a handy tool for Linux users that allows you to analyze how much space individual files and directories are taking up on your file system. It is also straightforward to use and it will quickly provide you with the size of everything in the current directory, including subdirectories. The following tutorial will demonstrate common examples of the du command in a Linux terminal environment.

• Please note it is best to run the du commands in the root account, or you may need to add sudo to the command depending on the area or permissions set for the directories, such as system files, as they may not be accessible without root permissions.

=> ↺ From The Chief Editor’s Desk…

• New Year’s celebrations are virtually synonymous with making New Year’s resolutions. Unfortunately, most New Year’s resolutions barely last a month, and by February, are a distant memory. According to an article on BestLife, only 55 percent of resolution-makers are still working on those resolutions after one month. An article on Fit & Well paints an even grimmer/dimmer picture of New Year’s resolutions. According to that article, most New Year’s resolution-makers ditch their “goals” just 17.8 days into January. This is so prevalent that January 17th is (unofficially) known as “ditch New Year’s resolutions day.” Wow! They don’t even make it three weeks!

• Personally, I make the same New Year’s resolution every year, and I’ve got quite a streak going for not breaking it. My annual New Year’s resolution is to not make a New Year’s resolution.

Open Hardware/Modding

=> ↺ Make your own micro FPV drone racing gate | Arduino Blog

• Drone racing is an increasingly popular hobby, especially as high-performance drones get more and more affordable. Racing drones can reach 200mph and a huge part of the skill set necessary for competition is the pilot’s ability to navigate through gates at high speed. Those gates mark check points on the course, a bit like the gates that slalom skiers go through. Drone racing gates can also track time, which is the case with this DIY micro FPV drone racing gate built by YouTuber ProfessorBoots.

• This is an affordable gate meant for indoor micro FPV drone racing. It is big enough to accommodate some larger drones, but the pilot would have to have stellar finesse. For micro drones, it is perfect. The gate detects the presence of a passing drone and can time laps, recording each lap and allowing the pilot to see their best time. It also has a ring of LEDs for visibility. If desired, the user can program those LEDs to flash when a drone passes through.

• Our plugin-based Network Block Device server, nbdkit, now has support for libblkio.

• libblkio is a library written by Stefan Hajnoczi, Alberto Faria, Stefano Garzarella and others for accessing some somewhat unusual disk protocols including vhost-user, NVMe, vDPA, VFIO and io_uring which I’ll talk about below. It’s important to know that these are not disk formats (like raw or qcow2), but accelerated protocols for talking to virtual or real hardware.

• The library is written in Rust (but offers a C API) and I believe it’s intended to replace various bottom-end parts of the qemu block layer at some point in the future.

• Zig also ships with a C/C++ compiler, and Zig can be used with either or both languages.

=> ↺ Bucket sort C++

• Sorting is a method by which we order the items in a sequence. Bucket sort is one of the sorting algorithms but this algorithm is a bit different from the other algorithms. A bucket, as the name implies, contains something in a separate space like a container. This algorithm places the elements in the bucket according to the condition. The elements are divided into different buckets, and sorting is performed on each bucket. We can decide which algorithm is used to sort the buckets. The other names for bucket sort are bin sort and radix sort. The grouping of elements to be stored in buckets is done uniformly. Bucket sort is the algorithm that is good with small arrays. But when it comes to sorting the larger arrays, this algorithm is not preferred because the complexity increases and the performance decreases. This algorithm is applied mostly on the floating point values where we need to uniformly group the elements of the array.

=> ↺ Dynamic Memory Allocation in C++

• Memory allocation is determined at the time of variable declaration. But in most cases, we don’t know how much memory is required for a specific variable. In that case, memory allocation has to be done on the runtime. The runtime memory allocation of the program is known as dynamic memory allocation. In dynamic memory allocation, we don’t know the actual size of the variable. We manually allocate the memory for that variable, and it can also be an array or object of a class. Pointers play a key role in dynamic memory allocation. When we dynamically allocate the memory, the “new” keyword is used to tell the compiler that we are dynamically allocating the memory. When we are done with allocating the memory, in the end, we need to manually “delete” that reserved dynamic memory. In other programming languages like Python and Java, we don’t have to dynamically allocate the memory because the compiler automatically does that. But in C and C++, we do this manually using the new (to reserve space) and delete (to free space) keywords.

=> ↺ Why Perl is making a comeback: 5 reasons why it’s worth learning – Linux Careers

• Perl is making a comeback, and for good reason. From its strong support for text manipulation and data processing tasks to its wide array of libraries and modules, Perl is a versatile and powerful language that’s worth learning. In this article, we’ll explore 5 reasons why Perl is making a comeback and why it’s worth learning now. Whether you’re a seasoned programmer or just starting out, Perl is a valuable skill to have in your toolkit.

• Perl is a popular programming language that is widely used in the tech industry for tasks such as web development, data processing, and system administration. Its simplicity, flexibility, and power make it a good choice for those looking to pursue a career in the tech industry. In this article, we will explore the strengths of Perl and discuss why it may be a good choice for those looking to learn a programming language. We will also compare Perl to Python, another popular programming language that is often used for similar types of tasks, and discuss the situations where one language may be a better choice over the other.

Shell/Bash/Zsh/Ksh

=> ↺ Bash Remove Last x Characters From String?

• There are several ways or commands in Linux that we may use to remove the last characters from a string value in bash, including “cut”, “sed” “compliment”, “awk” and others. The “%” and “?” operators can also be employed to eliminate the ending element from a string. By utilizing the “cut” command in bash, we can also delete a specific character from a string that we want to eliminate. In this article, we will show a variety of techniques for deleting elements from sequences.

=> ↺ How to Export a Path in .Bashrc

• When a command is launched on Linux, the operating system looks in the environment variable which is known as PATH for executable files. When we employ these paths, we can run the commands without having to provide a specific path.

=> ↺ Create Bash Functions with Arguments

• To create efficient code, bash functions are used in shell scripts. In essence, these are a set of instructions that can be used again throughout the program. Additionally, it enables programmers to divide long, complex scripts into manageable chunks that may be invoked as needed. In this article, we will go through how to pass an argument to a bash function to build a function with an argument. The parameter may be a string, an integer, or something else entirely. Different methods of sending arguments to bash functions will be used in this article.

=> ↺ Bash Loop Through Files In A Directory?

• Sometimes according to our requirements, we need to move and loop through all the files and directories in a given folder. Let us suppose we want to run a specific command in each folder and file of a directory. For that purpose, we will iterate through all directories using loops. Only a few CLI utilities or command line utilities allow us to run the same command for multiple files. But in our case, we use bash shell scripting and using for loop to speed up any command we want to make our work efficient.

=> ↺ Bash Cut Command with Examples

• Linux provides us with many commands and utilities that allow us to cut out pieces and parts of specific files and process and filter those files. “cut” is also a command line utility in Linux that allows us to cut specific parts and sections of files and show us the data as standard output by printing it.

Rust

=> ↺ Rust projects open to denial of service thanks to Hyper • The Register

• Security researchers at have identified multiple vulnerabilities arising from careless use of the Rust Hyper package, a very popular library for handling HTTP requests.

• Security firm JFrog found that an undisclosed number of projects incorporating Hyper, like Axum, Salvo and conduit-hyper, were susceptible to denial of service (DoS) attacks arising from HTTP requests crafted to take advantage of the vulnerabilities.

• Those three have fixed their code, but an undisclosed number of other vulnerable projects have not yet responded, according to JFrog. Currently, 2,579 projects listed in Rust’s package repository crates.io depend on Hyper, which has been downloaded more than 67 million times.

Leftovers

=> ↺ Bring back personal blogging

• In a recent piece for The Verge, Monique Judge made a pretty compelling argument on behalf of the personal blog. We’ve all been talking for years now about the cracks and rot forming in most/many social media platforms. But what if what’s next is what came before? Especially poignant is the way Judge links personal blogging to community building. It all made me a little teary-eyed for the days when I used to open up my computer and check my favorite sites and blogs, all of which I had bookmarked in my browser. Launching my tabs to check on Jeremiah’s Vanishing New York, Waiter rant, The Sartorialist, even Perez Hilton (I must admit), was definitely more satisfying (and far less chaotic) than opening up Twitter.

=> ↺ Why Canada Had to Ban 1.5-Liter Glass Soda Bottles in 1979

• In the summer of 1979, Canadian grocery stores had a problem. It was a product design problem, and it was one that involved a specific size of soda bottle. As soda became an increasingly popular drink, consumers demanded more sizes so that they could drink more and save some of it for later. These days, we think nothing of this shift, beyond the obvious environmental and health implications of drinking so much soda. But the conversation was different in the late 1970s, especially in Canada, where the soda bottles had one significant difference from the modern ones that mattered quite a lot—they were made of glass, and as it turns out, large glass bottles and soda don’t mix. Today’s Tedium talks about the year Canada recalled pop.

=> ↺ Is “no grid” the smartest grid of all? | Stop at Zona-M

• The Grid in “Smart Grid” is the electric grid, that is the whole network of transmission lines, substations and other equipment that distribute electricity from power plants to their end users. Electric grids worldwide are aging, and regardless of age could not cope with the “increasing complexity and needs of electricity in the 21st Century” anyway. The solution is to make them Smart Grids, that is grids that, thanks to digital technologies, can “move” electricity back and forth among utilities and customers in real time, in the safest and most efficient way.

Internet

=> ↺ Faster Internet makes bad citizens?

• “In the UK, the diffusion of broadband has resulted in a decrease in civic and political participation. On the other hand, it does not seem to have affected the strong ties among relatives and friends. The phenomenon could also explain the rise of populism.”

• “A one standard deviation reduction in the distance between the phone line of the people interviewed for the study and the closest network node, which is a good indicator of a faster connection, caused the likelihood to participate in membership activities to decrease by 4.7 percent between 2005 and 2017. For political parties and trade unions, the decrease in the probability of involvement rises to 5.1 percent.”

• These works include The Case Book of Sherlock Holmes, the last of Conan Doyle’s Sherlock Holmes stories (meaning all of the Holmes stories are now public domain), Agatha Christie’s The Big Four, and Upton Sinclair’s Oil! (which the film There Will Be Blood was based on).

Personal

=> ↺ Halberts and Knives

• With the recent OGL discussion, my thoughts are back with Helmbarten, my German Fantasy 2d6 game, which was translated into English as Halberts by @frotz@mstdn.games and @phf@tabletop.social and play-tested by @PresGas@freeradical.zone and the three of us. I was wondering how to provide a zero-to-hero experience using it.

• As it stands, you roll on your career tables, betting that you’ll survive and get better vs. strokes of fate taking you out. After a while, you decide you’re done. Your character won’t advance in levels, learn new skills, get better, or any of that. That all happened during character generation. Now the adventure begins.

=> ↺ Unexplained: After COVID I Can Run 10K a Day

• I am well into my 50′s. I’ve never been a fitness nut, preferring sitting in front of the computer or some other sitting project. In my childhood I had experienced a series of respiratory infections, scarring in my lungs, visible on x-rays. Most of my life I had a hard time with a 10-minute jog. For no good reason I can now run for hours.

• I had toyed with running, but I had trouble breathing. Around the Central Park reservoir, I would wind up completely out of breath (way before finishing the 1.4-mile loop), heart pounding and lungs jumping out of my burning larynx as I would recover, bent over and dizzy. Every time — in my twenties, thirties and forties.

Politics

=> ↺ The Written Word is Senile

• I don’t know how long until people cannot use pens, but it seems their days are numbered.

• Whatever time it might take, certain stages seem inevitable.

• Those currently in the government seem unlikely to change the education system to remove pens. I find it more likely that a group who broadly haven’t used a pen more than once a decade would find it natural to remove teachings they’ve never used.

=> ↺ The Plot Against America

• I’ve had a number of discussions with friends about government in the last year or so. They’ll claim that government doesn’t work and that no government is ever any good. Having some ancom leanings of my own, I can understand and sympathize with that point of view. What my friends don’t understand is that the US government isn’t working because it has been deliberately sabotaged for decades. I’ve had to make the case a few times, so it is worth putting down in writing.

Technical

=> ↺ Innovation (2010)

• For every occasion, my wife and I gift board games to each other, so we can play them together. This time made no exception. After browsing BoardGameGeek for a while, I bought her “Innovation”, a game where you must create a prehistoric civilization and guide it through the ages using innovations until the information era.

• We usually tend stay away from too complex or too strategic games, mostly because it takes too much time and effort to setup, and we end up never playing it. I was also looking for a game that might have a deeper game play the usual kind that we love (Codenames, Chroni, etc.).

=> ↺ Reading Ebooks Using Emacs!

• I assume the ‘nov’ stands for ‘novel’, but I’m not sure.

• I found a plugin for Emacs, that gives it the ability to read e-books! Well, epubs at least. I haven’t tried other formats. I installed it both on my Librem Mini and my Pinephone with ‘sudo apt install elpa-nov’. The easiest way to bring up the ebook is to type ‘emacs MYDOC.epub’ at the Terminal, and it pops right up (or ‘emacs -nw MYDOC.epub’ for those of us who want to stay in Terminal).

• To access ‘nov’ commands, use Meta-x nov, and hit tab once or twice and you will get the list of commands available. For those newer to Emacs, the Meta key is usually the Alt key (though you can reset it, and I think it is different on Mac). So – Alt-x and type ‘nov’ and press Tab key a couple of times.

Internet/Gemini

=> ↺ Trying out my own gemlog

• I am by no means a writer. I may have grown up a native english speaker, but my words don’t reflect that. I have always gotten a C or worse in my english classes, and writing essays has always been an arduous task for me. Despite this, I want to write gemlogs. I can’t yet articulate why I want to write a blog of sorts, but I think it has something to do with wanting to be a part of the gemispace community.

Programming

=> ↺ Proprietary algorithms

• We’ll inevitably encounter algorithms in our day-to-day life, but it matters that we should not succumb to the manipulation that’s going on by proprietary ones.

• Proprietary algorithms, such as the ones used on commercial social-media or search engines, actively manipulate us with the data they gather from our usage of their platforms. Algorithms decide trends, what becomes popular or not, and largely play a part in the daily happenings of the world. This is why it’s important to not get swayed by them at every step, sabotaging our view of the world, with an artificially customised one by the platform owners.

• We’ll encounter them sooner or later, even if one steers clear of manipulative platforms, such is the task that we should try to seek if a curated view is presented, by hiding information, purposefully giving more importance to a view point and so on.
