=> ↺ Docker Ps Show Full Command

• According to its official website, Docker is a containerization platform. It enables programmers to package applications into capsules, which have been standardized executable portions that integrate program code only with OS packages and prerequisites needed to execute on nearly any architecture.

• The Docker architecture has provided a terminal service that allows everyone to run a variety of instructions to get information from vessels or containers. Dockers have different instructions that are used for various purposes. One of the most-known commands is the “docker ps” command that is used to get information regarding the docker containers currently available in your docker framework. So, we have decided to use this article to illustrate how the “docker ps” instruction works and how we can see the overall full instruction at our Linux shell using the “—no-trunc” option in it.

• To start, we will be logging in from our system and using the “Ctrl+Alt+T” for the terminal console to start quickly. You have to delete all the already installed old packages docker along with other related packages from Ubuntu 20.04 system. So, the apt-get instruction has been utilized so far followed by the keyword “remove” and the names of packages to be removed. Add your current account password and press the Enter key to continue it.

=> ↺ How Do Ansible Filters Work?

• One of the primary parts of any framework or management software is the way it handles and processes data. Considering the direction in which the world of information technology is going, it is fair to say that data is king. Huge amounts of data are being generated daily to be used for different purposes. Thus, data management and processing very important. Software such as Ansible is required to handle huge amounts of data. Looking at the facilitations these types of applications are supposed to provide, their data processing capabilities must be top-notch.

• Whenever we need to process, format, or manipulate data in Ansible, we use filters. There are two sets of filters available in Ansible. One set is the jinja2 template filters and the other set is of the custom-built filters made by users.

• However, in the background, all the filters are derived from the jinja2 template, which works in a way that the data being input into the filters is first converted into template expressions so the filters can be applied to them.

• Another important point to take note of is that all the filters are applied locally, meaning that no filtering can be done using remote hosts. So, all the manipulation and processing take place on the Ansible control machine.

• If you are looking to learn about the filters available in Ansible and how they are used, you have found the right article as we will be guiding you on how these filters work and how you can create Ansible playbooks to process data the way you want your system to.

=> ↺ 2022 is officially the Year of Linux Gaming | GamingOnLinux

• That’s it, I’m done, finished. It’s “mission complete” now is it not? 2022 is officially the Year of Linux Gaming. Yup, that’s something I am now proclaiming and I’m also putting a flag down into February 25 (the Steam Deck release date) as Linux Gaming Day every year.

• While the long-running joke of “Year of the Linux Desktop” might take forever to actually be a thing, Linux Gaming is now a lot more mainstream. Thanks largely to Valve of course bringing over Steam to Linux, and eventually producing the Steam Deck — putting the power of Linux and open source literally into peoples’ hands.

• Of course that’s not to say it’s all Valve. There’s a massively long list of open source contributors who have helped to make this happen. From drivers to desktop environment upgrades there’s so many different people, companies and organisations to thank. We wouldn’t see the Steam Deck without open source and without the Vulkan API. I’ve said for years that we needed “hardware, hardware, hardware” with more vendors to properly jump in. It’s not enough to have good marketing, or a good desktop, people needed a reason to use it to actually sway them over and clearly the Steam Deck is doing wonders.

• If you follow the Steam Deck Reddit, you’ll see a lot of people trying out (and actually enjoying) the KDE Plasma desktop mode on the Steam Deck too. Plenty of the fixes coming into KDE Plasma are as a result of people trying it out too, and finding issues, which then benefits all users. You only have to look at the regular This Week in KDE blog posts from developer Nate Graham to see how much effort goes into it.

=> ↺ Status update, 15/04/2022 – Sam Thursfield

• As i mentioned last month, I bought one of these Norns audio-computers and a grey grid device to go with it. So now I have this lap-size electronic music apparatus.

• Its very fun to develop for – the truth is I’ve never got on well with the “standard” tools of Max/MSP and Pure Data, I suspect flow-based programming just isn’t for me. As within an hour of opening the web-based Lua editor on the Norns device I already had a pretty cool prototype of something I hadn’t even intended to make. More on that when I can devote more time to it.

• There is some work to make the open-source Norns software run on the Linux desktop in a container. It seems the status is “working but awkward.” I thought to myself – “How hard could it be to package this as a Flatpak?”

• The LimeSurvey releases an open-source version to let people use this tool in a self-hosted environment, making it quite easy for Raspberry Pi users to use the LimeSurvey services.

=> ↺ Tracking the harmful particulate pollution from wildfires intelligently | Arduino Blog

• As wildfires continue to get more prevalent throughout the world, new methods are required in order to track not just their flames which destroy forests and buildings, but also the vast quantities of fine particulate matter that gets thrown into the sky from the smoke. Fine particulate matter that ranges between 2.5 and 10 microns (PM 2.5 and PM 10) can cause serious health problems for anyone who breathes them in, which is what inspired Grace McNally to create a monitoring system as part of element14’s Just Encase Design Challenge.

=> ↺ Best Arduino Starter Kits

• To begin with making electronic projects there are different kits available that include essential components that are required by the to make projects. Also, Arduino kit comes with a complete guide of how you can make multiple projects and also gives a list of projects that can be made from that respective kit.

=> ↺ Best Arduino Simulators

• The first step for creating a project is to create a logic on how the controller will work and once we have created a pseudo code, we write and compile the Arduino code. Now comes the very important part as we have to design a circuit and to implement that circuit in the hardware. Before implementing the circuit in actual hardware to be sure that our project gives the desired output and all the connections of the components are correct, we run a simulation first. To create simulations of Arduino projects there are number of simulation software available and to save time of learners we have carefully shortlisted some of the best simulation software and have given brief information about each Arduino simulator:

=> ↺ Firefox Presents: A makeup artist with alopecia redefining beauty online

• With her face and bald head as her canvas, she creates wildly elaborate and colorful makeup designs that have gained her more than 177,000 followers on TikTok. She’s transformed herself into an Easter bunny, the Cheshire cat and Homer Simpson. Once, she turned herself into Bernie Sanders from that 2020 inauguration meme.

• Abby, an L.A.-based makeup artist, didn’t always feel comfortable with people’s gaze.

• In 2006, while in high school, she started to notice clumps of hair falling out in the shower. She and her mother made multiple doctor’s visits outside her small town in Montana until she received a diagnosis: alopecia, a condition that causes hair loss as a person’s immune system attacks hair follicles by mistake.

Functions such as window spawning and terminal emulation are just some of the parts of Emacs that are hidden to the casual user. This article aims to shed light on some of those in order to allow you to make the the most out of your Emacs installation.

Programming/Development

=> ↺ In the Land of Columns and Characters

• As discussed in those posts, while there are definite drawbacks and challenges in basing an app on a fully custom UI toolkit, there are also unbeatable advantages. One of those is the freedom to adapt and transform the UI without limitations, like I’ve already done to have versions of Lagrange built specifically for the Mac, Windows, Linux, *BSD GUI desktops, and the iOS, iPadOS, and Android mobile operating systems. (iPadOS is worth mentioning separately as there are some unique UI variations for the tablet form factor.)

• GUIs are nowadays quite the common denominator, but in the grand scheme of computing they are relative newcomers. For decades before GUIs, various text-based terminal interfaces were the norm. I’m sure most people reading this are already very familiar with the terminal, as it remains crucial to this day for many use cases, especially when one is connecting to a server over the network. Just like Gemtext, a text-based UI is fast and easy to stream over a network connection, be it a simple command line or something more complex.

• One thing that really interests me in the Lagrange project is exploring the boundaries of native cross-platform programming, because I fundamentally dislike the notion that modern cross-platform apps need to be based on a web browser for things to make sense. With the major desktop and mobile platforms now supported by the app — at least in Beta form — I’m setting sights on more exotic frontiers, and the terminal is a logical next step.

• comp.infosystems.gemini is the first new newsgroup since eight years in the Big-8 hierarchy of Usenet! Let’s celebrate!

=> ↺ Re: Do we want to revive the mailing list of gemini?

• I wasn’t involved in the creation of gemini. But since gemini is up and running, wouldn’t it be better to have gemini discussions on gemini?

• If we feel that gemini is lacking for using for communicating, maybe that’s something that we really should discuss.

=> ↺ C++ Sprintf

• In the C++ programming language, you will come across many conversions and copy data from one file or one variable to another, like the conversion from int to string, character array to string, etc. A similar type of conversion will be discussed herein in which the characters from the format strings are written to the buffer. And the values will be obtained through that buffer variable. This is done through a function in C++ known as sprints().

=> ↺ Dijkstra’s Algorithm C++

• Dijkstra’s algorithm is also known as the shortest possible path algorithm. It is the procedure to find the shortest path between the nodes/ edges of the graph. The shortest graph of a tree is created by starting from the source vertex to all the other points in the graph.

=> ↺ Fopen in C

• The fopen() function creates and correlates a stream with the file defined by the name of the file. The mode attribute is a sequence of bytes that indicates the sort of access to the file that has been provided. The positioning argument precedes additional keyword arguments in the mode attribute. Lowercase letters should be utilized for these positioning arguments. The keyword arguments might be specified in either upper or lower case. Quotation marks are used to separate them. There would only be a single indication of a keyword declared.

• Any file accessed is frequently determined by the file title given to the fopen() function. There are a variety of file-naming guidelines that we will use to design an application. Customizable characters and readable characters are arranged into sections in text files. A newline character is being used at the end of every line. The system can introduce or transform command characters in an outcome textual stream.

• Binary files are made up of a string of characters. The program will not transform control bits in input or output for these files. In this article, we’ll explore how to use the fopen() function to perform different operations in C.

=> ↺ How the C programming language has grown | Opensource.com

• The C programming language will turn fifty years old in 2022. Yet despite its long history, C remains one of the top “most-used” programming languages in many “popular programming languages” surveys. For example, check out the TIOBE Index, which tracks the popularity of different programming languages. Many Linux applications are written in C, such as the GNOME desktop.

=> ↺ Status update, April 2022

• This month marked my first time filing taxes in two countries, and I can assure you it is the worst. I am now a single-issue voter in the US: stop taxing expats! You can get some insight into the financials of SourceHut in the recently-published financial report. But let’s get right into the fun stuff: free software development news.

• There was some slowdown from me this month thanks to all of the business and financial crap I had to put up with, but I was able to get some cool stuff done and many other contributors have been keeping things moving. I’ll start by introducing a new/old project: Himitsu.

• Essentially, Himitsu is a secret storage system whose intended use-case is to provide features like password storage and SSH agent functionality. It draws much of its inspiration from Plan 9’s Factotum. You may have stumbled upon an early prototype on git.sr.ht which introduces the basic idea and included the start of an implementation in C. Ultimately I shelved this project for want of a better programming language to implement it with, and then I made a better programming language to implement it with.

• Below, we take a look at where various states and the respective state governments stand with regard to the Pegasus revelations made in July 2021. We also take a look at the various inquiries that may have been initiated as a fallout from the revelations.

• [..]

• The Pegasus revelations demonstrated a need for urgent surveillance reform to protect citizens against the use of such invasive technologies which hamper their fundamental right to privacy and threatens the democratic ideals of our country. It has been used against constitutional functionaries such as an Election Commissioner, a Supreme Court Judge and members of Parliament but most disturbingly against activists and journalists. Use of such surveillance technology on journalists has a chilling effect as it precludes them from working and reporting on sensitive matters, some of which may also be against the ruling government, without jeopardising themselves and the personal safety of their sources. It also stops human rights defenders from working with vulnerable people, some of whom may have been victimised by their own government, without opening them up to further abuse.

=> ↺ Irving Wladawsky-Berger: The 2022 AI Index Report: AI’s Emerging Real-World Impact

• On March 16, Stanford’s Institute for Human-Centered Artificial Intelligence (HAI) released the 2022 AI Index report, its fifth annual study on the impact and progress of AI. The comprehensive study was led by an interdisciplinary group of experts from across academia and industry, and highlights the rapid rate of technical and marketplace AI advances, as well as the growing ethical and regulatory concerns associated with AI.

• “2021 was the year that AI went from an emerging technology to a mature technology – we’re no longer dealing with a speculative part of scientific research, but instead something that has real-world impact, both positive and negative,” said Jack Clark, co-chair of the AI Index. “This year’s AI Index tells us that AI is being integrated into the economy and the effects of it are beginning to go global across research, deployment, and even funding.” Two weeks ago I attended an online HAI seminar where Clark gave this excellent presentation on the AI Index.

• The report is organized into five chapters: Technical Performance, AI Ethics, R&D, Economy and Education, and Policy and Governance. Let me summarize the key findings of each chapter.

Digital Restrictions (DRM)

=> ↺ Apple Hardware Rentals — The Repair Association

• What happens if Apple no longer sells cell phones and rents them instead? Not much. For years the cell carriers rented hardware by the month on a multi-year contract, and consumers weren’t horribly upset. So long as Apple continues to force customers into regular replacements – the rental concept is more honest than the pretense of a sale without having the advantages of ownership.

• We’ve argued for years that a company that demands total control over their assets should not sell those assets in the first place. Retaining ownership is essential to having full control. But retaining ownership has accounting implications for Apple, that might not be so advantageous.
