      • How To Install Angular CLI on Fedora 35 - idroot

        In this tutorial, we will show you how to install Angular CLI on Fedora 35. For those of you who didn’t know, AngularJS is a JavaScript framework that is used to develop web apps. It has MVC (Model-View-Controller) architecture. Angular CLI is used in Angular projects to automate tasks rather than perform them manually. Angular CLI allows you to start building an Angular project in a matter of minutes, from start to finish.

        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 Angular CLI on a Fedora 35.

      • 2 ways to install XFCE Desktop on Debian 11 Bullseye - Linux Shout

        Xfce is an alternative to GNOME or KDE and a pretty colorful and well-configurable desktop environment. Learn the commands to install XFCE desktop on Debian 11 Bullseye Linux.

        Xfce is designed to run easily on slightly less powerful computers, mainly because of the somewhat lower system requirements. This lightweight desktop environment is very easy to use with the mouse and can be used to run all GNOME and KDE programs. Friends of Compiz can use Xfce too.

        Ubuntu has been available with Xfce as the desktop environment in its official version – Xubuntu. However, since it is no longer a “pure” Xfce (various GNOME components have been integrated to increase comfort). Nevertheless – if you are a Debian Linux user with a command-line interface or graphical user interface with Gnome or any other, still we can install XFCE directly using the official Debian package source repository.

      • AV Linux MX-21 has arrived, and it's almost a multi-media creator dream come true | TechRepublic

        I must confess, I do love creating video and audio content. I’ve recorded thousands of videos over the years, hundreds of podcast episodes, ebooks and much more. I’ve experimented with different applications for different purposes. Eventually, I arrived at a collection of tools that best fit my needs. Some of those tools are open-source, while others are not. For example, I use Audacity for audio and Final Cut Pro X for video. Why do I not opt to go with an open-source video editor? Mostly because none of them have either reached a level of reliability or they don’t offer the features I need to create pro-level content.

      • blog.ipfire.org - Introducing elementary network protection: Dropping all traffic from and to hostile networks by default

        Starting with upcoming Core Update 164, the firewall options page will feature a new checkbox: Drop packets from and to hostile networks. For basic protection of our users and their networks, it will be enabled by default on new installations, staying disabled on existing IPFire systems (but we recommend to turn it on there as well).

        Improving network protection for the masses

        Although we always preach IPFire is not meant to be installed and then forgotten, we believe this is what happens to a decent amount of installations out there: They are set up once, perhaps being configured in a basic manner, and do not receive any attention afterwards. Resources are scarce, so why bother touching a running system?

        Of course, we neither endorse such a modus operandi, nor can we shed the load from our users to define and enforce a proper security policy (including firewall rules and IPS settings, just to name a few ingredients) on their networks.

        On the other hand, there are some shady areas of the internet, and virtually everyone in the security community knows about them. A subset of them is so dangerous that you don't even want to process any IP connection from or to them, no matter what.

        • TrueNAS SCALE 22.02 Is a Game Changer in the Linux NAS Field

          After 18 months of development and testing effort, TrueNAS SCALE is now released as a newest addition to the TruNASs family of storage software.

          First off, let me start with what is TrueNAS SCALE. TrueNAS SCALE is built on the same foundational software and middleware as TrueNAS CORE, which is probably the best known, the world’s most widely deployed, and powerful free and open-source storage software out there.

          TrueNAS SCALE is the first release of TrueNAS on Linux. It is Debian-based as opposed to the original which ran on FreeBSD, and that greatly increases the available tools to a user that wants better control and additional features over their networked storage devices.

        • Neither old nor new: The CIO’s paradox

          Each year around this time people ask, "what’s the big trend?" or "what’s the new technology we should be watching?" But the truth is, immediately adopting the "next big thing" isn’t the best strategy for CIOs, trivializing the longevity and impact of IT in an organization. Some technology persists for decades if not longer, and the decisions IT leaders make today can affect their organizations’ nimbleness and market response down the road, whether it’s in two years or 20. As new infrastructure is being built out, you can’t just leave behind existing systems and tools. That’s not practical or sustainable. So how do you maintain existing systems that are critical to your operations while still keeping pace with a rapidly evolving IT world?

        Back in 2016, we covered the launch of the original Pigeon RB100 automation controller, which was built around the flagship, ARM11 based Raspberry Pi Compute Module. Since then, Kristech has upgraded the RB100 with a Raspberry Pi Compute Module 3 in its Pigeon RB100-CM3 and released more advanced CM3 based systems with the Pigeon RB300-CM3 and RB350-CM3. The company has now launched a Pigeon RB700 system built around the Raspberry Pi CM4.

      • diziet | Rooting an Eos Fairphone 4

        Last week I received (finally) my Fairphone 4, supplied with a de-googled operating system, which I had ordered from the E Foundation’s shop in December. (I’m am very hard on hardware and my venerable Fairphone 2 is really on its last legs.)

        I expect to have full control over the software on any computing device I own which is as complicated, capable, and therefore, hazardous, as a mobile phone. Unfortunately the Eos image (they prefer to spell it “/e/ os”, srsly!) doesn’t come with a way to get root without taking fairly serious measures including unlocking the bootloader. Unlocking the bootloader wouldn’t be desirable for me but I can’t live without root. So.

        I started with these helpful instructions: https://forum.xda-developers.com/t/fairphone-4-root.4376421/

        I found the whole process a bit of a trial, and I thought I would write down what I did. But, it’s not straightforward, at least for someone like me who only has a dim understanding of all this Android stuff. Unfortunately, due to the number of missteps and restarts, what I actually did is not really a sensible procedure.

        • Pressure Gauge Built In A Vacuum

          Necessity might be the mother of all invention, but we often find that inventions around here are just as often driven by expensive off-the-shelf parts and a lack of willingness to spend top dollar for them. More often than not, we find people building their own tools or parts as if these high prices are a challenge instead of simply shrugging and ordering them from a supplier. The latest in those accepting the challenge of building their own parts is [Advanced Tinkering] who needed a specialty pressure gauge for a vacuum chamber.

          In this specific case, the sensor itself is not too highly priced but the controller for it was the deal-breaker, so with a trusty Arduino in hand a custom gauge was fashioned once the sensor was acquired.

        • 1960s stereo console modernized with an Arduino | Arduino Blog

          The aphorism that “they don’t build them like they used to” is especially true of the consumer electronics industry. Most manufacturers today design their product to last only a few years — or with outright planned obsolescence. But mid-century stereo consoles were a different story and resembled high-end furniture that would last. Sherman Banks has a Penncrest stereo console from that era, but its electronics were failing. So he used an Arduino to modernize the unit while retaining the vintage appearance.

          This particular console had an AM/stereo FM radio receiver and a built-in phonograph turntable. Unfortunately, the aging electronic components were unreliable and lacked good sound quality. The console itself, however, was in fantastic shape. So Banks wanted to keep it looking as original as possible, but with modern electronics and all of the features they offer. He replaced the radio with a Denon DRA-800H stereo receiver that offered inputs for a turntable and SiriusXM receiver, as well as Bluetooth streaming and Ethernet connections. He also replaced the turntable with a new Denon DP-29F.

            I do realize that there's a consistency problem and maintenance cost to my tweaks. After all, I cannot possibly account for every little change in the Firefox UI ever, and there might be tiny glitches occurring now and then. But then, these will be minor, and I will have quick fixes for them, whereas using a browser with sub-optimal looks all the time is a no-go. It's not a fun situation, but even so, Firefox is still the best browser around, and you should be using it, for practical and philosophical reasons, hipsterology notwithstanding.

            Anyway, if you are a nerd, because let's face it, otherwise you wouldn't be here, and you like your things to be neat, clean, legible, ergonomic, and efficient, then you will have changed the Firefox UI looks in versions 91 and beyond. You might even be possibly using some of my tweaks. If so, you have a fresh round of polish, in case you encounter some small niggles with Firefox 97. There you go. Take care, and see you soon.

We've created for this a group of RMS attackers (RMS is the pioneer of copyleft), who even publicly defended this practice...]

            Software Freedom Conservancy announces a Committee On AI-Assisted Programming and Copyleft to develop recommendations and plans for a Free and Open Source Software (FOSS) community response to the use of machine learning tools for code generation and authorship. The ethics and morality of machine learning models, which are regularly being applied to many problems, are a serious concern to policy makers. This Committee will focus on the specific issue of AI-assisted programming using models trained with FOSS, such as we've seen with GitHub's Copilot product. Microsoft, through their GitHub subsidiary, argues, without evidence, that use of Copilot (which has been trained with a large body of FOSS) is “fair use” of that FOSS, and that all output of Copilot is solely copyrighted by its users. This conclusion focuses on the legal details of issues rather than ethics and morality, and Microsoft and GitHub have refused to provide backing evidence. This Committee will focus on the ethics and morality of their position, and consider the proper policy positions for the FOSS community and copyleft activists in the advent of AI-assisted programming.

          One might wonder why then, with those upgraded skills, I didn’t seize the opportunity to make a new website for GTG or other open-source projects that could benefit from fancier marketing.

          The short answer is, even if my tooling and technique have improved, it’s still a metric crapton of work. It might seem easy (“Use Hugo!”, “Just slap a couple of pages together!”, etc.) but there’s much more to building a website than just the technical design and coding (or integration) aspects. This article provides you with an idea of the amount of time it takes to plan, write, design and build a “reasonably simple” website with a dozen pages or so.

            I’ve been working on some linting projects at $work and one thing I’m working on is finding unused variables in our codebase. This can be pretty important in a larger codebase. When you find variables which have not been used, you may find yourself asking, “why is this here?” and you may not easily get an answer. Eliminating unused variables can be good for the performance of the code, but also good for everyone else on your team. So, we want to make sure we can remove old bits of unused code and also prevent new cases.

            One tool we have used for this is Test::Vars. It has some limitations (like it needs to be in a file with a package declaration) and it has some bugs, but it does find some unused variables as well.

        While Star Trek’s transporter is hard to imagine — perfect matter movement across vast distances with no equipment on one end — it may not be the most far-fetched piece of tech on the Enterprise. While there are several contenders, I strongly suspect the universal translator is the most unlikely MacGuffin. After all, how would you decipher a totally unknown language in real-time? Of course, no one wants to watch 30 episodes of TV about how we finally figured out what Klingons call clouds, so pretty much every science fiction movie has some hand-waving explanation for speaking the viewer’s language. Farscape had microbes, some aliens have telepathy that works with alien brains of any kind, and still others study English from afar for decades off camera. Babelfish anyone?

      • Big Chemistry: From Gasoline To Wintergreen | Hackaday

        Most of us probably have some vivid memories of high school or college chemistry lab, where the principles of the science were demonstrated, and where we all got at least a little practice in experimental methods. Measuring, diluting, precipitating, titrating, all generally conducted under safe conditions using stuff that wasn’t likely to blow up or burn.

        But dropwise additions and reaction volumes measured in milliliters are not the stuff upon which to build a global economy that feeds, clothes, and provides for eight billion people. For chemistry to go beyond the lab, it needs to be scaled up, often to a point that’s hard to conceptualize. Big chemistry and big engineering go hand in hand, delivering processes that transform the simplest, most abundant substances into the things that, for better or worse, make life possible.

        To get a better idea of how big chemistry does that, we’re going to take a look at one simple molecule that we’ve probably all used at one time or another: the common artificial flavoring wintergreen. It’s an innocuous ingredient in a wide range of foods and medicines, but the infrastructure required to make it and all its precursors is a snapshot of just how important big chemistry really is.

      • How Big Is The Moon? Figure It Out Yourself | Hackaday

        We have to confess that we occasionally send friends a link to “let me Google that for you” when they ask us something that they could have easily found online. Naturally, if someone asked us how big the moon is, we’d ask Google or another search engine. But not [Prof Matt Strassler]. He’d tell you to figure it out yourself and he would then show you how to do it.

        This isn’t a new question. People have been wondering about the moon since the dawn of human civilization. The ancient Greeks not only asked the question, but they worked out a pretty good answer. They knew approximately how big the Earth was and they knew the moon was far away because it is seen over a very wide area. They also knew the sun was even further away because the moon sometimes blocks the sun’s light in an eclipse. Using complex geometry and proto-trigonometry they were able to work out an approximate size of the moon. [Matt’s] method is similar but easier and relies on the moon occluding distant stars and planets.

        [Matt] explains that a distant sphere illuminated by a distant light source will cast a shadow on a plane about the size of the sphere. What’s more, is that anyone on the plane in the shadow who can’t see the light source must be in the shadow, which allows you to measure the shadow, and that gives an approximation of the sphere’s size. For this to work, the light source needs to be at least ten times further away from the plane than the sphere is. The further away the light source is, the lower the error in the final number.

      • Levitating With Light | Hackaday

        Of course, it is no secret that light can exert pressure. That’s how solar sails work and some scientists have used it to work with aerosols and the like. But this appears to be the first time light lifted a large item against gravity. The team claims that their tests showed that a sunlight-powered flying vehicle might carry up to ten milligrams of payload. That doesn’t sound like much, but it’s impressive and the paper mentions that since the lift is not from aerodynamic forces, there might be applications in flying at very high altitudes.

        We’re all used to personal computers as the norm, be they mobile, laptop, or desktop. But of course, in the early days, computers were large single-purpose machines used to crunch even bigger numbers. Go back even further in time, and the computers are humans operating fancy electromechanical calculators at high speeds, or, simply using pencils or chalk.

        Before the personal computer arrived, people had to share time on mainframe machines to do their computing. Imagine having to go down to the library every time you wanted to look something up on the Internet. Wouldn’t you much rather do it at home on your own machine? Of course you would.

      • Coin Cell Eliminator Does More Than Save Batteries | Hackaday

        Coin cells are useful things that allow us to run small electronic devices off a tiny power source. However, they don’t have a lot of capacity, and they can run out pretty quickly if you’re hitting them hard when developing a project. Thankfully, [bobricius] has just the tool to help.

        The device is simple – it’s a PCB sized just so to fit into a slot for a CR2016 or CR2032 coin cell. The standard board fits a CR2016 slot thanks to the thickness of the PCB, and a shim PCB can be used to allow the device to be used in a CR2032-sized slot instead.

        Whether it’s an engine swap in an old car or pulling a hard drive out of an old computer, we often find ourselves transplanting bits from one piece of hardware to another. [Emily Velasco] recently attempted this with a pair of CRTs, and came away with great success.

        The donor was an old 1980s fishing sounder, which came complete with a rather fetching monochrome amber CRT display. [Emily]’s goal was to transplant this into the body of a early 2000s portable television. The displays were of a similar size and shape, though the Toshiba CRT from the 80s used a lot more glass in its construction.

        The tube socket in the TV used to hook up the display matched the old CRT perfectly, so there were no hassles there. A bit of soldering was all that was needed to hook up the yoke, and [Emily] was ready to test. Amazingly, it powered up cleanly, displaying rolling amber static as you’d expect, given that analog television stations have been off the air for some time now.

      • What To Do With A Broken Television When You Can’t Fix It | Hackaday

        Who can say ‘no’ to a free TV, even if it’s broken? This was the situation [Andrew Menadue] ended up in last year when he was offered an LG 39LE4900 LCD TV. As [Andrew] describes in the blog post along with videos (see first part embedded after the break), this particular television had been taken to a television repair shop previously after the HDMI inputs stopped working, but due to a lack of replacement parts the owner had to make due with the analog inputs still working. That is, until those stopped working as well.

        The nice thing about these TVs is that they are very modular inside, as [Andrew] also discovered to his delight. In addition to the LG controller board, an inverter board and the power supply board, this TV also contained a TCON PCB. After some initial unsuccessful swapping of the parts with EBay replacements, nothing was (surprisingly) working, but it did turn out that the TCON and inverter boards are made and sold by AUO (major Taiwanese display manufacturer), along with the display itself.

      • Winding Your Own Small Coils | Hackaday

        Depending on what you build, you may or may not run into a lot of inductors. If you need small value coils, it is easy to make good-looking coils, and [JohnAudioTech] shows you how. Of course, doing the winding itself isn’t that hard, but you do need to know how to estimate the number of turns you need and how to validate the coil by measurement.

        [John] uses a variety of techniques to estimate and measure his coils ranging from math to using an oscilloscope. He even uses an old-fashioned nomogram from a Radio Shack databook circa 1972.

        In fact, we get the idea that [John] really misses Radio Shack. In addition to the book, we noted guest appearances from a Radio Shack calculator and a caliper. We were a bit surprised that he didn’t use a Radio Shack pen as a coil form.

      • Minimalistic Doorbell Doesn’t Need An Internet Connection – Or Even a Power Supply

        Doorbells are among those everyday objects that started out simple but picked up an immense amount of complexity over the years. What began as a mechanism to bang two pieces of metal together evolved into all kinds of wired and wireless electric bells, finally culminating in today’s smart doorbells that beam a live video feed to their owners even if they’re half a world away.

        But sometimes, less is more. [Low tech obsession] built a doorbell out of spare components that doesn’t require Internet connectivity or even a power supply. But it’s not a purely mechanical device either: the visitor turns a knob mounted on a stepper motor, generating pulses of alternating current. These pulses are then fed into the voice coil of an old hard drive, causing its arm to vibrate and strike a bell, mounted where the platters used to be.

          • 'Hundreds of computers' in Ukraine hit with wiper malware [Ed: Microsoft Windows TCO; The cyberattack in Ukraine is a Microsoft Windows thing, but Microsoft-sponsored media keeps throwing in the word "Linux" to confuse and distract.]

            It's not entirely clear right now how the malware is dropped onto victims' machines and run, though in one case, said ESET, an organization's Active Directory server was probably compromised to distribute the wiper through the network via a group policy object.

          • Anatomy of top-tier suspected NSA backdoor code [Ed: It seems like topic shifting now that Russia batters Windows, mostly in Ukraine]

            Pangu Lab has identified what it claims is a sophisticated backdoor that was used by the NSA to subvert highly targeted Linux systems around the world for more than a decade.

            The China-based computer-security outfit says it first spotted the backdoor code, or advanced persistent threat (APT), in 2013 when conducting a forensic investigation on a host in "a key domestic department" – presumably a Chinese company or government agency.

          • Chinese Researchers Detail Linux Backdoor of NSA-Linked Equation Group [Ed: Media desperate to associate Linux with security problem because Ukraine is besieged by attacks on Microsoft Windows at the moment?]

            A team of researchers from China’s Pangu Lab on Wednesday published a 50-page report detailing a piece of Linux malware allegedly used against many targets by the threat actor known as the Equation Group, which has been linked to the U.S. National Security Agency (NSA).

            It’s not uncommon for cybersecurity companies in the United States to publish reports detailing the tools and activities of threat actors linked to the Chinese government, and now a group of Chinese researchers have released a report detailing a piece of malware tied to the U.S. government.

            Pangu Lab is a research project of Pangu Team, which is best known for its iPhone jailbreaks. An iOS exploit earned them $300,000 last year at a major Chinese hacking contest.

          • New Sandworm Malware Cyclops Blink Replaces VPNFilter

            The United Kingdom’s National Cyber Security Centre, CISA, the National Security Agency, and the Federal Bureau of Investigation have released a joint Cybersecurity Advisory (CSA) reporting that the malicious cyber actor known as Sandworm or Voodoo Bear is using new malware, referred to as Cyclops Blink. Cyclops Blink appears to be a replacement framework for the VPNFilter malware exposed in 2018, which exploited network devices, primarily small office/home office routers and network-attached storage devices.

            • New Cloud Cybersafety, Malware Miseries, Snap Snafus Lavish Linux [Ed: "LinuxInsider" participates in FUD against "Linux" (Snap etc.)]

              Qualys Research Team discovered multiple vulnerabilities in the snap-confine function on Linux operating systems. The most important of which can be exploited to escalate privilege to gain root privileges.

              Successful exploitation of this vulnerability allows any unprivileged user to gain root privileges on the vulnerable host. Qualys security researchers have been able to independently verify the vulnerability, develop an exploit, and obtain full root privileges on default installations of Ubuntu.

              The Qualys Research Team confirmed the vulnerability. Then it engaged in responsible vulnerability disclosure and coordinated with both vendor and open-source distributions in announcing this newly discovered flaw.

              Snap is a software packaging and deployment system used in Linux distributions. Its packages make it easy to install applications with all their dependencies included to run on all major Linux distributions.

              Snap has become reasonably widespread in the Linux world with a number of major vendors distributing packages using it. While any exploit that can give root access is problematic, being a local exploit reduces the risk somewhat, noted Mike Parkin, engineer at Vulcan Cyber.

      • Upgrading my home internet; a story of yak shaving

        When I migrated my home connection to FTTP I kept the same 80M/20M profile I’d had on FTTC. I didn’t have a pressing need for faster, and I saved money because I was no longer paying for the phone line portion. I wanted more, but at the time I think the only option was for a 160M/30M profile instead and I didn’t need it and it wasn’t enough better to convince me.

        Time passed and BT rolled out their GigE (really 900M) download option. And again, I didn’t need it, but I wanted it. My provider, Aquiss, initially didn’t offer this (I think they had up to 330M download options available by this point). So I stayed on 80M/20M. And the only time I really wanted it to be faster was when pushing off-site backups to rsync.net.

        Of course, we’ve had the pandemic, and that’s involved 2 adults working from home with plenty of video calls throughout the day. The 80M/20M connection has proved rock solid for this, so again, I didn’t feel an upgrade was justified. We got a 4K capable TV last year and while the bandwidth usage for 4K streaming is noticeably higher, again the connection can handle it no problem.
