Linux is not just an operating system but more about a mindset of being open and reliable to all. I am one of the fans in the Linux fan club who wants to share my awesome experience of using Linux for years with all the HackerNoon readers.
Argentina is a country in the southern half of South America. Argentina shares borders with Chile to the south and west, Bolivia and Paraguay to the north, and Brazil, Uruguay, and the Atlantic Ocean to the east.

Microsoft software engineer Stephen Hemminger has proposed removing the DECnet protocol handling code from the Linux kernel putting the final full stop on the long history of protocol wars.
As it stands no one cares about DECnet any more. Red Hat's Christine Caulfield flagged the code as orphaned in 2010. VMS was the last even mainstream OS to use it.
Kid3, the popular Qt audio tag editor, released version 3.9.2 today. PPA updated for Ubuntu 22.04, Ubuntu 20.04, and Ubuntu 18.04.
The new Kid3 3.9.2 is a bug-fix release. Though, there are new features including .dff support, an audio format developed by Sony and Philips for Super Audio CD (SACD).
New features also include support for chapters in MP4 audio books, importing from URLs containing search results from Discogs and MusicBrainz, and a Norwegian translation.
Hello, friends. In this post, we will tell you a little about how to install QT Creator on Ubuntu 22.04.
software minimalism is key for stability, maintainability, security and performance

I have a bone to pick with someone. I honestly don’t know who to point this ire toward, but there’s a big problem now with using Ubuntu Server as a base for Kubernetes.
Over the past few days, I’ve attempted, over and over, to get Kubernetes up and running on Ubuntu Server 22.04, and, no matter how many times I’ve attempted, it fails. Now, I can get Kubernetes installed on Ubuntu Server without a problem, as I’ve done so many times before. The only difference is now, instead of using Docker, I have to use a runtime like containerd.
The following bash script gets the user input by using the read command and then printing out the results in the terminal.
One of the more unusual Linux commands is named “yes”. It’s a very simple tool intended to help you avoid having to answer a lot of questions that might be asked when you run a script or a program that needs a series of responses to do its work.
If you type “yes” by itself at the command prompt, your screen is going to start filling up with the just the letter “y” (one per line) until you hit control-C to stop it. It’s also incredibly fast. Unlike what you see displayed below, yes will likely spit out more than a million y’s in the time it likely takes you to reach down and press control-C. Fortunately, that’s not all that this command can do.
Prometheus is a free and open-source monitoring and alerting tool that was initially used for monitoring metrics at SoundCloud back in 2012. It is written in Go programming language.
Prometheus monitors and records real-time events in a time-series database. Since then it has grown in leaps and bounds and had been adopted by many organizations to monitor their infrastructure metrics. Prometheus provides flexible queries and real-time alerting which helps in quick diagnosis and troubleshooting of errors.
Python virtual environment is used to create an isolated environment for Python project which contains interpreter, libraries, and scripts. You can create any number of virtual environments for your projects with each having its own dependencies.
By using virtual environments you avoid installing packages globally which could break other projects.
Ansible is an open-source configuration management and application deployment tool. It helps to reduce managerial overhead by automating the deployment of the app and managing IT infrastructure.
Using ansible we are going to install apache2 web server in Ubuntu 22.04. For this, we need to create a configuration in YAML syntax called Ansible playbooks.
Normally, there is a control node and host nodes. Ansible is installed in the control node and will execute A basic Ansible environment has three main components: control node, managed node, and inventory. Ansible is installed in the control node and will execute the ansible playbook to deploy in managed nodes using the inventory file in the control node that describes the managed nodes to Ansible. In this lab, we are going to install and use it on a single node and it's configurable for multiple nodes as well.
We explain various ways to fix the Could not get lock /var/lib/dpkg/lock Error in Ubuntu Linux and related distributions.
The new version 21 of the Just Perfection extension allows even deeper than before customization of your GNOME desktop.
GNOME, like any other working environment, is not perfect. In fact, GNOME is perhaps one of the most criticized Linux desktop environments for its approach to interacting with and using it.
Fortunately, GNOME allows the end user to change this functionality according to their requirements and tastes by installing optional tiny applications called extensions.
Version 4.3.1.1 was announced on August 2, 2022:
https://bkhome.org/news/202208/easyos-32-bit-dunfell-series-version-431.html
For 4.3.2, I have added SeaMonkey, version 2.53.13, and bumped Limine to 3.14.1.
The NetBSD Project is pleased to announce NetBSD 9.3, the third release from the NetBSD 9 stable branch.
It represents a selected subset of fixes deemed important for security or stability reasons since the release of NetBSD 9.2 in May 2021, as well some enhancements backported from the development branch. It is fully compatible with NetBSD 9.0. Users running 9.2 or an earlier release are strongly recommended to upgrade.
Aside from many bug fixes, 9.3 includes backported improvements to suspend and resume support, various minor additions of new hardware to existing device drivers, compatibility with UDF file systems created on Windows 10, enhanced support for newer Intel Gigabit Ethernet chipsets, better support for new Intel and AMD Zen 3 chipsets, support for configuring connections to Wi-Fi networks using sysinst(8), support for wsfb-based X11 servers on the Commodore Amiga, and minor performance improvements for the Xen hypervisor.
This week’s BSD Now takes its title from one of the links talking about how cat(1) works, which reminds me of this article about how the very original implementation of grep was crazy fast.
If you’ve ever dreamt of making money with a Raspberry Pi, now is your chance! Maker and developer OfficialFlance, as they’re known as over at Reddit, has created a project that both restores old hardware and provides an opportunity to earn a little money on the side. The project relies on a Raspberry Pi 4 to bring functionality back to a broken vending machine.
According to OfficialFlance, the development process began after they came across an old vending machine online. The original hardware was far from operational thanks to broken lights and a burnt-out motherboard. Out of everything used to power the machine, only the motors were still functional. At this point, OfficialFlance decided the best board to drive the project would be a Raspberry Pi.
MQTT ( Message Query Telemetry Transport) is one of those protocols that are taken for granted. It just works, with minimal effort, and it has been with us in various forms since 1999. MQTT is bandwidth efficient, lightweight and it can be used on devices with very little resources, including the new $6 Raspberry Pi Pico W. With just 264KB of SRAM, the Pico W relies on clever coding and lightweight protocols, and this is where MQTT comes in.
We’ve already covered how to control a Raspberry Pi Pico W via web services such as Anvil and sent live sensor data to Twitter via IFTTT. But with MQTT we can effortlessly send and receive data with a Raspberry Pi Pico W, and use it with multiple devices across the globe.
Graphics processing, and possibly machine learning applications, just took a step forward on the Raspberry Pi 4 (opens in new tab). In a blog post (opens in new tab) by Raspberry Pi CEO Eben Upton - that the popular single-board computer is now conformant with version 1.2 of the Vulkan graphics API.
Raspberry Pi (opens in new tab) owners who want to use the surprisingly versatile SBC as an everyday computer rejoice - again! - as yet another new operating system drops. Unsurprisingly, as reported by Phoronix (opens in new tab), it’s another flavor of Linux: Fedora, one of the biggest names in free operating systems. It's also, supposedly, the distro Linus Torvalds himself uses. Fedora has signed off on support for the Raspberry Pi 4 (opens in new tab), as well as the Pi 400 (opens in new tab), and the Compute Module 4 (opens in new tab).
The official Raspberry Pi operating system, Raspberry Pi OS, is Linux-based. That means it’s not too uncommon to find yourself running terminal commands. This project, created by maker and developer Arseny, who posted the details under the name kotofey_magnus on Reddit, showcases a new way to log terminal interactions by printing them on a thermal receipt printer in real-time.
When users type a command into terminal, it prints out the command. When the Pi processes the input, the response is then printed on the printer right after. This creates a physical GUI and literal paper trail by logging the terminal interactions on the printer.
Conversions of 8bit computers into something more modern using a Raspberry Pi (opens in new tab) board aren’t unheard of, but how far can you go back? How about 19th-century technology, in the form of a typewriter? That’s precisely what GitHub user Riley, AKA Artillect (opens in new tab), has done, as reported on Hackaday (opens in new tab). However, the choice of typewriter is more 1980s than 1880s.
We’ve seen a few Raspberry Pi TVs in the past, including this retro TV simulator and The Simpsons-themed TV that plays episodes from the animated sitcom. But this is the first time we’ve seen a Pi-powered TV dedicated to playing live streams from Twitch streamers. Created by a maker named Bob (also known by his handle Rsheldiii), this custom Twitch TV can be programmed to start playing any live stream of choice as soon as it’s active.
The hardware is housed inside a purple, 3D-printed shell resembling the twitch.tv logo. Bob configured the system to play in real-time at full volume when a stream begins. He describes it as a “twitch.tv TV, a twitch.tv TV made to look like twitch.tv that plays twitch.tv on its uh... monitor.”
The Firefly Station M3 is a Mini PC built around the eight-core Rockchip RK3588S System on Chip (SoC) released this year. This fanless Mini PC comes in an aluminum case and it can support up to 16GB of RAM and 128GB of eMMC flash.
The Rockchip RK3588S SoC combines four Cortex-A76 cores, four Cortex-A55 cores, a six TOPS Neural Processing Unit (NPU) and an ARM Mali-G610 GPU with support for OpenGL ES 3.2, OpenCL 2.2 and Vulkan 1.1.

Are you the C++ experienced reader to solve the following challenge?

While asking around, some approaches have been prpoposed, but so far none could satisfy the second goal, catching existing ambiguous argument expressions to hint API consumers to adapt them.
Would you have an idea?
Edit: On a second thought, similar problems also exist before C++17 already when an argument has a type which can be implicitly converted both to A and B, by implicit constructors or type operator methods.

Instead for now, I have to answer with: "well you see... support for proc macros was broken in rust-analyzer for folks who used a nightly rustc toolchain, due to incompatibilities in the bridge (which is an unstable interface in the first place), and it's bound to stay broken for the foreseeable future, not specifically because of technical challenges, but mostly because of human and organizational challenges, and I think I've found a way forward that will benefit everyone."
I don’t appreciate just how much baristas act like councillors. I wonder if they’re vetted by their managers for additional soft skills like this? They must be.
Every morning I go to my favourite local coffee shop, and the baristas are always talking with customers about their day, the weather, what problems they’re currently facing, how the long weekend wasn’t long enough. Some lend a sympathetic ear, others are actively involved in mediation or working out solutions in between running the coffee grinders, the espresso machines, the filter drips, and asking if they wanted almond milk instead of skim lactose free.
My cognitive ability limits my multitasking to unpacking dishwashers while tailing server logs and listening to a podcast, and those require no external human input! Imagine if I was trying to figure out how Alice can talk with her estranged son, or if I had to offer inspiring words of encouragement to Bob for his job interview.
Folk music icon and much-loved Australian entertainer Judith Durham has died aged 79.
Durham made her first recording at 19 and later achieved worldwide fame as lead singer of The Seekers after joining the group in 1963.
The trio became the first Australian group to achieve major chart and sales success in the United Kingdom and United States, eventually selling 50 million records.
The volcano, named Fagradalsfjall, erupted southeast of Keflavik Airport and southwest of Iceland's capital Reykjavik.
Iceland's colossal Fagradalsfjall volcano erupted not far from its capital's airport on Wednesday afternoon — and judging by the photos captured by adventurous onlookers, it was certainly a sight to behold.
According to The Washington Post, the eruption took place roughly ten miles from the Keflavik International Airport and 20 miles from the Icelandic capital of Reykjavik.
Fortunately, no injuries have been reported so far, despite many curious onlookers flocking to the site to witness the awe-inspiring scene, which one volcano enthusiast described as a "dancing fire," as quoted by the WaPo.
A video recorded at the scene shows a writhing mass of burning lava, blowing copious amounts of smoke into the air.
State and federal authorities are worried the number of Australians getting their third dose of COVID-19 vaccine is flatlining.
Some 71.4 per cent of eligible Australians, or just over 14.1 million people, have so far received a third dose. But there are more than 5.6 million yet to get their booster. The concern comes amid almost 29,000 new virus cases recorded across the nation on Saturday along with 89 deaths.
While decreasing daily over the past week, the number of virus patients in hospital care also remains a touch under 4500 or accounting for almost one in 12 hospital beds.
A new botnet has been observed targeting Linux devices by launching brute-forcing attacks on weak or default credentials in order to gain access to SSH servers. Researchers said the botnet’s persistence features and limited distributed denial-of-service (DDoS) capabilities both set it apart from other IoT malware families and also make its primary motivations a mystery.
Victims are offered the decryption key without payment, but the prank demonstrates how easy such an attack can be

For decades, the United States has conducted indiscriminate mass surveillance of its citizens, as well as of foreign governments, companies and individuals. Various surveillance projects implemented by Washington have been unveiled one after another in recent years, exposing more evidence of America's pervasive and ubiquitous surveillance of the world.
The United States District Court for the Eastern District of Virginia indictment of Julian Assange is a curious document. By the end of it you can’t help feeling that if anyone is to be indicted, it should be the US Government and the CIA.
The U.S. should not be threatening journalists, like Julian Assange, with espionage charges for reporting on classified information.
Julian Assange is the world’s most famous prisoner – now incarcerated in Britain’s Belmarsh Prison – as he fights extradition to the US on charges stemming from his WikiLeaks platform having published hundreds of thousands of secret documents and deeply sensitive emails. I spoke to his father John Shipton, who is leading a campaign to free him.
More than six years after the passing of Prince, his estate is officially settled, according to a newly filed court order.
Today I knocked together a German language clone of Stacksmith's Spellbinder. I'm calling it Zaubuchstabier, even if I'm not sure how well that works as a pun.
So please don't let this stand in the way of gradual change, and please don't take it as "don't even start if you can't do it perfectly", that's definitively not how I feel, I'm really grateful for any change people are making. Please keep up the good work.
I am glad that human being like you are here to create tension against a predictable behavior like mine! Your contribute is essential to make this space better!
Raylib is a pretty nice minimal library for constructing games, kind of a modernized SDL. It does not a game engine, it's just a way to construct a frame loop and an api with useful code for drawing, texture-mapping, loading shaders and whatnot.
The CL bindings in cl-raylib are buggy and possibly incomplete, but usable for the simplest of demos. I am pretty good with CFFI and debugging, so within the first day I managed to fix a couple of bugs and convert another example. Feels pretty good to enjoy coding again.
The initial findings that posture equaled power have been debunked, but body language can still play a part in your success.
Been almost a year since I updated anything here. Probably the latest change was when I pulled in changes to gmnisrv at the end of last year. Almost surprised the server is still running, I guess I configured a systemd unit file for it and thus the server came back up every time I restarted the box.
I managed to stay fairly consistent on here from May of 2020 to September 2021 and basically after that my activity here just crashed. It's very likely the silence would have continued even longer had I not played some Last Call BBS on my Owncast stream yesterday. Some people talked in chat about BBS's and Gopher and that made me think back to Gemini and this little capsule of mine that has been drifting through cyberspace dormant and essentially on reserve power.
