        Cassandra is, along with MongoDB, one of the most popular NoSQL databases at the moment. Cassandra is designed as a scalable, fail-safe system for handling large amounts of data on distributed systems (clusters). Unlike CouchDB and MongoDB(C++), this one is written in Java like Apache HBase. Since version 0.8, the Cassandra Query Language has been introduced, a SQL-like query language that can serve as a simple interface.

        In this tutorial, we will show you how to install MariaDB on Rocky Linux 9. For those of you who didn’t know, MariaDB is a popular, free, and open-source database management system commonly used as an alternative for the MySQL portion of the popular LAMP. It uses MySQL as its primary storage engine, but it is also lightweight, secure, and features in-memory ACID transactions.

        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 MariaDB 10 database on Rocky Linux. 9.

      • Robbie Harwood: Shim Ab Booting Poc

        I’ve implemented a proof-of-concept for “A/B booting” of shim itself. Concretely, this means that when a shim fails to boot, an older version will be tried as a fallback. This aims to increase the stability and reliability of shim updates. Booting the older shim is a stop-gap and not something we want systems to be regularly doing, so the situation is detected and reported for admin attention.

      • TechRepublicHow to install that latest version of Docker on AlmaLinux | TechRepublic

        AlmaLinux is a Red Hat Enterprise Linux clone, which means it doesn’t ship with Docker installed. In fact, most RHEL-based distributions are now defaulting to Podman. Although Podman is a close drop-in for Docker, I still have a penchant for the original, so I prefer to use that technology over its replacement.

        The problem is that installing Docker on an RHEL-based distribution isn’t exactly straightforward. It’s not hard, but without knowing the right steps or flags to use, you’ll find it almost impossible to get Docker installed.

      • FOSSLinuxHow to install Yarn on Ubuntu | FOSS Linux

        Yarn is an npm-compatible JavaScript manager that aids in the automation process of setting up, updating, configuring, and removing npm packages. NPM is an abbreviation for Node Package Manager. It is an install manager for the Node JS platform. NPM is well-known as the world’s most extensive software registry. And as such, open-source DevOps across the globe utilize it to publish and share their source code.

        The NPM package comprises three components; The first is the website that permits you to look up third-party packages, set up profiles, and manages your packages. The second is the command-line interface or npm CLI that runs from a command-line/terminal to permit your interaction with npm. The third is the registry, an extensive public database of Javascript.

        Ideally, what Yarn does is parallelize the system operations to boost resource utilization, and cache downloaded packages to save bandwidth. It is secure, and verifies each installed package’s integrity using checksums before executing its code. As such, it is very reliable because of its detailed but concise lock file format; it also ensures that a setup that works on a machine will explicitly perform in the same way on a different device.

      • HowTo GeekHow to Compare Binary Files on Linux

        Linux is rich in ways to compare and analyze text files. The diff command will compare two files for you, and highlight the differences. It can even provide a few lines on either side of the changes to provide some context around the changed lines. And the colordiff command adds color to make visually parsing the differences even easier.

        Developers and authors use diff to highlight the differences between different versions of program source code files, or draft texts. It’s fast and easy, and you don’t need any technical skills to see the differences between strings of text.

        In the world of binary files, things aren’t so simple. Binary files are not composed of plain text. They’re made up of many bytes containing numeric values. If it’s a compressed file such as a TAR archive or a ZIP file, those values represent the compressed files that are stored inside the archive file, along with the tables of symbols that are required for the decompression and extraction of the files.

      • Unix MenA Guide to Using Bash Arrays: Examples

        The Bourne Again Shell is the default shell on virtually every Linux distribution. While it’s not as fleshed out as most programming languages, it is considered a programming language by many.

        Software engineers are accustomed to using the Linux command line to navigate several aspects of development. Linux administrators rely on it fully to complete their tasks.

        However, Bash arrays tend to remain one of the more obscure features of the CLI. Besides, the questionable syntax results in many developers turning away from using the arrays.

        Bash arrays are primarily utilized to store data in an indexed manner. You can compare it to storing data in variables, with the difference being that Bash arrays allow you to call back the data using predictable indexed numbers. Furthermore, Bash arrays also allow you to create associations.

        Bash arrays are an often-overlooked aspect of Bash scripting, mastering which can enable you to customize administrative tasks, run several tasks simultaneously, and even automate tasks. They are an invaluable tool to any Linux power user since using the arrays is necessary when working with scripts that store a large volume of information.

        • OMG UbuntuThese are the Best New Features in GNOME 43 – OMG! Ubuntu!

          The all-new GNOME 43 is fast approaching, with a stable release due next month. As you’d expect, it brings a barrage of new features and cool capabilities with it.

          And this post? Why, it only goes and spoils the surprise by spotlighting the most notable improvements on offer in GNOME 43 — but I’ve a feeling you don’t mind!

          GNOME 43 continues to build out from the design direction laid in GNOME 40. There’s a major redesign of the system menu, a slew of new GTK4/libadwaita app ports, and further effort to improve the small-screen usability of several of this leading free desktop’s core apps.

          Do keep in mind that GNOME 43 is in beta. It’s possible that some things you read about below will be revised, altered, or maybe even axed —!— by the time GNOME 43 is released in mid-September. This list is also not exhaustive; if there’s something really cool I’ve missed let me know about it in the comments!

          [...]

          GNOME 43 is scheduled for release in mid-September. The GNOME 43 beta is out and available to test, though how you get tit will vary from distro to distro. Ubuntu 22.10 is due for release in October and will likely feature most of the changes mentioned in this article, but not all.

        If you’ve ever had the pleasure of riding a motorcycle on a track, then you know that it quickly becomes competitive — even if the competition is yourself. You want to cut your lap times, increase your lean angle, brake later after a straight, and accelerate harder as you come out of a turn. But the only way to get objective data on your improvement is to monitor your real performance. This device designed by Jesus Soriano collects that data so that you can track your progress from one track day to the next.

        There are commercial products on the market that provide similar functionality, but they’re expensive and give you little control over operation. This project utilizes open hardware, so you can hack it to your heart’s content and save some money that is better spent on tires. The important components include: an Arduino Nano 33 IoT board, a TinyCircuits GPS shield, a SparkFun Power Supply Stick, a Bitcraze Micro SD Card Deck, and a 1000mAh lithium-ion battery. Soriano simply stuffed those components in his motorcycle’s tail storage area under the seat, but you could always 3D-print a dedicated enclosure if your bike doesn’t have tail storage.

With the Raspberry Pi PIco W, a Wi-Fi enabled micro controller that costs just $6, you can do some basic web serving.

        The Raspberry Pi Pico W isn’t the most obvious choice, but with a little MicroPython code, and some HTML, we can serve basic, static web pages from a Pico W. There are two parts to this project. The HTML and the MicroPython code. The HTML is what our browser will see, and MicroPython acts as the means to serve the code.

        For this project we will host a basic web page from a Raspberry Pi Pico W. We will also demonstrate how to add a little more sparkle to your pages with CSS and JavaScript. Finally we will serve the content to the world by learning how to forward external requests to our Raspberry Pi Pico W.

      Recently, I rewatched a movie I hadn’t seen in years, Willy Wonka and the Chocolate Factory. It’s still a classic but, by the end, I felt differently about it than I remembered. When Gene Wilder says, “But Charlie, don’t forget what happened to the man who suddenly got everything he always wanted … he lived happily ever after,” I felt like I saw Wonka for the real trickster that he is. Charlie is a child, unlikely to know what he really wants. And Wonka doesn’t seem especially happy with his “ever after.” This might be a leap but, this led me to think about the nature of what it means to be successful on different terms. Especially in the creative fields, where fame and fortune are often elusive, many are left to define their success without either. Today’s Tedium is looking at a number of different professional fields to see what we can glean from the blank’s blank (actor’s actor, comedian’s comedian, writer’s writer, and even the pilot’s pilot and lawyer’s lawyer), a phrase template used to describe a certain type of success and achievement.

      • The Next PlatformNvidia Shows What Optically Linked GPU Systems Might Look Like

        We have been talking about silicon photonics so long that we are, probably like many of you, frustrated that it already is not ubiquitous. But the good news is that advances in electrical signaling, after hitting a wall a decade ago when the talk of practical silicon photonics interconnects first really got going, continued to evolve and we have not really had to resort to silicon photonics yet.

        With electrical interconnects between components being far less expensive, this has been a boon for the price numerator part of the price/performance equation, even though silicon photonics has an advantage in the denominator performance part of that equation. Over time, electrical signaling is getting shorter and shorter as the bandwidth goes up, and it is getting noisier and noisier, too. The day will inevitably come where we will shift from electrons to photons as electromagnetic signaling method and from copper to fiber optic glass as signaling media.

        This curve, from a presentation that Nvidia chief scientist Bill Dally gave at the Optical Fiber Communication conference way back in March, makes the case pretty well:

        As we’ve seen in the previous article, a browser extension isn’t very different from a website. It’s all the same HTML pages and JavaScript code. The code executes in the browser’s regular sandbox. So what can websites possibly gain by exploiting vulnerabilities in a browser extension?

        Well, access to extension privileges of course. Browser extensions usually have lots of those, typically explicitly defined in the permissions entry of the extension manifest, but some are granted implicitly. Reason enough to take a closer look at some of these permissions and their potential for abuse.

        In this article, we explore what Red Hat Insights and Red Hat Satellite have to offer individually, and then we will look at how you can have a heightened experience of the two products with the use of Cloud Connector. We then evaluate both offerings by performing a feature-by-feature comparison of the tools for a better understanding of how they compare.

        Insights and Satellite are frequently used by customers for a myriad of use cases — some similar and some vastly different — including managing their IT estate. Ultimately, customers are able to proactively streamline the security posture of their IT estate with both or either of these products.

      • AccessNowSEC must demand greater transparency on digital and human rights issues in ESG ratings – Access Now

        For too long, greenwashing and opacity have let the true environmental and human rights impacts of information and communications technology (ICT) companies’ actions fly under the radar. Investors seeking reliable data about the environmental, social, and governance (ESG) performance of these companies deserve more, and better, information about the societal impact of their technologies.

        Open MIC, Heartland Initiative, and Access Now submitted comments urging the U.S. Securities and Exchange Commission (SEC), which is weighing rules and forming amendments on ESG practices, to help investors access accurate data about the ESG performance of the companies they back, in turn making more informed decisions.

        “Many ICT companies have poor governance practices and fall short on digital rights, labor rights, and other human rights issues,” said Audrey Mocle, Deputy Director at Open MIC. “Yet, ICT stocks are overrepresented in ESG funds due to the industry’s relatively low carbon footprint and high returns for shareholders. Investors need transparency into how ESG funds weigh each of the ‘E,’ ‘S,’ and ‘G’ criteria and the methods used to measure them.”

        After I wrote hledger, I got some good feedback, both from a friend in-person and also on Twitter.

        My in-person friend asked, frankly, do I really try to manage money like this: tracking every single expense? Which affirms my suspicion, that many people don’t, and that it perhaps isn’t essential to do so.

        Combined with the details below, 3/4 of the way through my experiment with using hledger, I’m not convinced that it has been a good idea.

        • Public KnowledgeHigh Court of Australia Finds Google Not a Publisher for Linking Articles – Public Knowledge

          Today, the High Court of Australia ruled that Google is not a publisher of the websites it links to in the case, Google LLC v Defteros. The ruling overturns a previous ruling in which the Supreme Court of Victoria determined Google was a publisher for linking to newspaper articles.

          In its ruling, the High Court explains that “a hyperlink is merely a tool which enables a person to navigate to another webpage” and, thus, facilitates access, but does not disseminate or publish the material. In a concurrence to the opinion, two of the High Court justices noted that the case did not involve material that was promoted by Google as part of a search result. These justices indicated that it could be a more closely argued case for attaching liability if Google and a third party have an agreement to promote content on the third party’s webpage.

          This ruling aligns with our 2021 principles on protecting free expression online in that it affirms the importance of 230-like protections for entities that provide access to user-generated content. Public Knowledge supports the decision.

      • Re: How Many Computers Do You Have?

        HiFive Unmatched — Debian unstable riscv64; 4 cores, 16 GiB RAM, 500 GB NVMe disk. This miniITX motherboard is mounted in a stone age LianLi “box”. Its clearly not a rocket, but it’s good enough for most of what I do. I am very impressed by the degree of integration of all the fiddly bits (bootloaders, kernel, devicetree, etc.). So clearly a lot of work has already gone into this platform. Thanks folks! I do use this machine as a development system for coding AVR microcontrollers in assembly and Forth. So git, make, emacs, perl, and avra are running to my liking.

      • I want the time wasted from solving captchas back

        Recaptcha is infamous for being the most user hostile captcha implementation. I feel like I spend up to 5 minutes wasting my time solving the same intractable street sign puzzles over and over, and if your browser is so much even slightly configured to be privacy conscious at all, you will be hit with the most difficult captchas and have to do it all over again.

        This is a multi-faceted problem that isn’t completely all on recaptcha. Many sites for example use Cloudflare, which is known to be hostile to Tor users, and browsing any site using Tor tends to present you with high difficulty captchas. It’s particularly egregious if captchas are sent on certain requests, meaning that you will have to solve it ALL OVER AGAIN even if you successfully solved the last one. Granted, this is configurable by the webmaster, but the fact that it’s encouraged or so prevalent at all discourages legitimate users from visiting your site.

        • Launch of Omloppsbanan, an Orbit for Swedish Geminauts

          I’ve hosted a Gemini capsule for a month now. I’d like to add something to my capsule that is not just static text, so I decided to make an orbit. An orbit is a bunch of Gemini capsules linking to each other in a ring. Each page has a link to the next and the previous page in the ring. This was popular on the early web under the name “webrings”. To make the orbit resilient to link rot, each navigation link goes via a central orbit service.

        • Sleepless Nights, Busy Days

          It has been nearly 12 weeks since I managed to do any programming. My head is brimming with coding ideas.

          It has been 2.5 weeks since the baby was born. I haven’t had more than three hours of sleep per night since then. Some days I manage to take a nap, allowing me to feel somewhat normal for a while. Of course, the daily schedule is so filled with frequent baby feeding and diaper changing, not to mention dog walks and cooking food, that I wouldn’t be able to sit down at a computer anyway.

          It feels like having constant jet lag. In a way, the arrival of a baby changes the daily rhythm completely, like traveling to a faraway foreign continent. It was the same way three years ago when my first child was born, although those times have already faded from memory, unsurprisingly. That’s what the “baby lag” does to you. The old muscle memory remains, though, with certain routines feeling very familiar.
