      • The New StackRust in the Linux Kernel - The New Stack

        Not that long ago, the idea that another major language would be supported in the Linux kernel would have been laughable. Linux was C’s poster child. Sure, there have been efforts to introduce other languages into the kernel, notably C++. They failed. Badly. As Linux’s creator Linus Torvalds once said, “C++ is a horrible language.” So, why is Torvalds now welcoming Rust into the kernel? Listen, my friend, and I’ll tell you.

      • The Register UKLinux 6.1: Rust to hit mainline kernel ● The Register

        The first big change for the forthcoming Linux kernel 6.1 is in… and it's a big one.

        Kees Cook made the pull request and Linus Torvalds accepted it earlier this week, meaning that Linux 6.1 will soon have direct support for Rust code, as teased earlier this week. The initial support is in the region of 12-and-a-half thousand lines of code.

        No, this doesn't mean that the kernel will start to be rewritten in Rust. There are already other Rust operating system kernels in development, such as Redox OS, and Linux is not, practically speaking, going to become one of them.

        What's interesting is that it's Rust that has made it. There are multiple languages vying to be successors to C, with C-like syntax but which extend C with new features. C++ was one of the first, which adds object oriented programming to C.

        A recent version of the Linux kernel can create a nasty flickering effect on Intel-powered laptops—to the point the problem may damage the display.

        The problem involves a bug in the 5.19.2 release for the Linux kernel. On Monday, an Intel software engineer named Ville Syrjälä noted(Opens in a new window) the software contains a “potentially bogus panel power sequencing delays, which may harm the LCD panel.”

        “I recommend immediate revert of this stuff, and new stable release ASAP. Plus a recommendation that no one using laptops with Intel GPUs run 5.19.12,” Syrjälä wrote in the Linux kernel mailing list.

        The good news is that the Linux team quickly rolled out(Opens in a new window) version 5.19.3, which seems to resolve the problem. Users can also downgrade their Linux release to 5.19.11 to prevent the flickering.

        Choosing the best remote desktop for Linux will enable you to access computers and mobile devices remotely from your Linux computer. But there are far fewer options available for Linux users than for Windows or Mac owners, and these tend to be much more difficult to use.

        This can make it hard to select the right option, particularly if you don’t want too steep of a learning curve. Many Linux remote desktops are open-source and versatile, but they also require significant tech skills to install and use.

        To help you find your way through the confusing jargon surrounding Linux remote desktops and select the right option for your business, we’ve put together this guide. In it, we take a close look at the leading Linux remote desktop programs available today.

      • Ubuntu Pit15 Best Compression or Archive Managers for Linux System

        Data archive or compression is a method or an algorithm that we can use to squeeze the volume of the data to make the size smaller. Data compression is helpful for storing files on a drive and sending them over the internet. When you decompress the data, it uses the reverse algorithm to make the files as it was. Compression or archive is essential for data analysis, storing, and transferring. If we look at Gmail’s file attachment section, we can see that it doesn’t attach files more than a specific size. In that case, you can use the archive tools to make the file size smaller. Plenty of free and open-source tools can do the data compression/archiving task in Linux.

      • DebugPointHow to Fix VirtualBox Kernel Headers Not Found Error

        When you run Fedora or any related distro (such as RHEL, CentOS, etc.) in VirtualBox as a guest, you get this error while installing the VirtualBox guest additions.

        The primary reason is the difference in Kernel versions between the guest and the host system.

        For example, if your host system has Linux Kernel 5.19 for example and you are installing any distribution with a different version, say 5.14, then you may run into this error while running the setup script for the virtual box guest additions.

        The VirtualBox guest addition set-up requires the necessary Kernel modules to be built inside the guest system. Then it checks whether the Kernel modules match; otherwise, it throws this error.

        For the average user, stability is vital regarding their computer. They don’t want to constantly update drivers or perform other maintenance tasks to keep things running smoothly. That’s why Linux distributions focusing on stability typically don’t include the latest and most significant drivers. Instead, they use the tried-and-true Mesa drivers. These drivers are free and open-source and support a wide range of graphic cards. However, they may not always be up-to-date with the latest hardware and technologies. As a result, you may need to periodically update your Mesa drivers to take advantage of new features and bug fixes using a LaunchPAD ppa that is well known.

        A new version of a quarter-century-old window manager shows that there's still room for improvement and innovation, even in established, mature tools.

        The world of Linux desktop environments is full of sound and fury, with a constant stream of new developments and new versions. Lots of them duplicate each others' work and functionality, sometimes just using slightly different tooling. All too often, ambitious or promising projects never reach version 1.0. Either they get abandoned or simply become moribund, and new updates stop appearing.

        It's easy to be distracted by this constant background noise and forget that there are simpler alternatives to a complete desktop, without going full Luddite and living at a console prompt. A trendy way to do this is with a tiling window manager, and alongside established favorites – for example awesomewm, i3, and ratpoison – there are lesser-known ones that are exploring new functionality such as bspwm, herbsluftwm, and Qtile. Lots of new tiling window managers are arriving on Wayland like cagebreak, dwl, newm, and river.

        As we reported back in July, the future direction of SUSE Linux Enterprise is starting to take shape, and it's containers all the way down.

        The Adaptable Linux Platform (ALP) prototype's internal version number is 0.01, so it has a long way to go yet, but it's ready for you to start experimenting. SUSE has already published some background information, and there's a 50-page manual too.

        After community feedback, the new OS will require only x86-64 version 2 support, not the version 3 support that was bruited earlier in the year.

        The first demonstration version, code named "Les Droites" after the first peak to surpass 4,000 meters in the Alps, is available for download.

        At this stage, two QCOW2 disk images for x86-64 machines are available: one unencrypted, and one with full disk encryption enabled. The plan is that this will support either conventional passphrase entry to unlock the image when the server or VM boots, or work with a hardware TPM chip, as SUSE Distinguished Engineer Olaf Kirch explains, with some demo code to match.

        Raspberry Pi is the most popular SBC – Single-Board Computer around the world. It can do pretty much everything a desktop computer can do and is suitable for all ages keen to explore computing. Raspberry comes with all the software; you require for basic computing. But if you want to extend the functionalities to some extent, you will need to take OS running on your device.

        It performs as a bridge between the user and Raspberry hardware. OS is the most crucial program that helps you to develop and execute programs. It enables the hardware to communicate with the software to generate meaningful interactions. Also, it manages CPU, memory, disk drives, printers, establishes user interface, and provides services for applications software.

        Although Raspbian is the official Raspberry Pi OS, other alternative operating systems are available to run on the Raspberry Pi projects.

        This isn’t about documentation alone. If documentation is part of a product, and documentation work is part of engineering, then it has implications for engineering too.

        Generally speaking, technical writing is a poorly-understood discipline in the software industry. It’s a specialised role, and though the skills that it requires are typically exercised privately, the results are very public.

        And yet, everybody seems to have confident opinions about documentation! For example, an engineer might bristle hotly with indignation if an outsider were to cast judgements or make pronouncements about software theory or practice – but not hesitate to do the same about technical documentation.

        Some of this is fair enough, and some of it must change.

      • ID RootHow To Install Lua Scripting Language on Ubuntu 22.04 LTS - idroot

        In this tutorial, we will show you how to install Lua Scripting Language on Ubuntu 22.04 LTS. For those of you who didn’t know, Lua is a lightweight, high-level, multi-paradigm programming language designed primarily for embedded use in applications. It’s an extensible and interpreted scripting language that is dynamically typed, and run by interpreting bytecode with a register-based virtual machine.

        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 Lua programming language on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.

      • Unix MenWhat is Linear Programming?

        Linear programming is a method for determining the best solution to a linear function. Making a few simple assumptions is the best technique for carrying out linear optimization. The objective function is referred to as the linear function. Relationships in the real world can be extremely complex. However, such relationships can be represented using linear programming, which makes it simpler to analyze them.

        Numerous sectors, including manufacturing, energy, telecommunications, and transportation, use linear programming. This article clarifies the various aspects of linear programming, including its definition, formula, approaches for using it to solve issues, and related examples.

        • Neo SmartImplementing truly safe semaphores in rust

          Low-level or systems programming languages generally strive to provide libraries and interfaces that enable developers, boost productivity, enhance safety, provide resistance to misuse, and more — all while trying to reduce the runtime cost of such initiatives. Strong type systems turn runtime safety/sanity checks into compile-time errors, optimizing compilers try to reduce an enforced sequence of api calls into a single instruction, and library developers think up of clever hacks to even completely erase any trace of an abstraction from the resulting binaries. And as anyone that’s familiar with them can tell you, the rust programming language and its developers/community have truly embraced this ethos of zero-cost abstractions, perhaps more so than any others.

      • New YorkerThe Thorny Problem of Keeping the Internet’s Time | The New Yorker

        In 1977, David Mills, an eccentric engineer and computer scientist, took a job at comsat, a satellite corporation headquartered in Washington, D.C. Mills was an inveterate tinkerer: he’d once built a hearing aid for a girlfriend’s uncle, and had consulted for Ford on how paper-tape computers might be put into cars. Now, at comsat, Mills became involved in the arpanet, the computer network that would become the precursor to the Internet. A handful of researchers were already using the network to connect their distant computers and trade information. But the fidelity of that exchanged data was threatened by a distinct deficiency: the machines did not share a single, reliable synchronized time.

        Over decades, Mills had gained wide-ranging expertise in mathematics, engineering, and computer science. In the early seventies, as a lecturer at the University of Edinburgh, he’d written programs that decoded shortwave radio and telegraph signals. Later, largely for fun, he’d studied how the clocks in a power grid could wander several seconds in the course of a hot summer’s day. (The extent of their shifts depended not just on the temperature but on whether the grid used coal or hydropower.) Now he concentrated on the problem of keeping time across a far-flung computer network. Clock time, Mills learned, is the result of an unending search for consensus. Even the times told by the world’s most precise government-maintained “master clocks” are composites of the readings of several atomic clocks. The master clocks, in turn, are averaged to help create international civil time, known as Coördinated Universal Time and initialized as U.T.C.

      Once, a few months ago, I went around my apartment apologizing to virtual assistants. Siri, Google Home—it wasn’t that I felt bad about anything, I just wondered what they would say. And they all had something to say. “It’s OK, Dayten.” “No problem.” Obviously the designers thought to program this in. It’s a little weird that they did, though—why assume humans would compulsively apologize to technology? Turns out we have a lot to apologize for. Today’s Tedium talks about humanity’s calamitous relationship with machines. (It has nothing to do with an imminent superintelligence takeover. It does have a little to do with demons.)

        About 5000 Australian staff of the local unit of global security firm G4S have been affected by a data leak following a ransomware attack in July on a work site, iTWire understands.

        The company offers services such as private security, prison management, cash transportation, care and justice, secure solutions and investigative services.

        In Australia, it operates under the name G4S Australia and has provided security at the Coalition Government's refugee detention centre on Manus Island sometime back. G4S also provides services in a number of prisons in Australia.

        The company says it employs more than half a million people around the world and claims it "plays a valuable and important role in society".

Marwa Fatafta, who is Palestinian, tweeted in response “Believe us when we say we are a surveillance testing lab in every sense of the word.”

          Fatafta is the Middle East-North Africa policy manager at the digital rights group Access Now and a policy analyst at the think tank Al-Shabaka which seeks to “educate and foster public debate on Palestinian human rights and self-determination.” Coda Story spoke with her to learn more about Israel’s use of surveillance technology in Palestine.

      • The Only Culture of Any Worth

        In the early morning, which it is certainly not, one must have tea. Having stated that it is not (necessarily) early morning, do I have the requirement for tea? Yes. I must have tea. Why do I require tea if it is no longer early morning? The reason is the following: tea is omnipresent during all phases of time. The "length" of any arbitrary phase of time is immaterial. Thus, even though the original statement was that one must have tea in the early morning and it is currently no longer early morning, one must still have tea. The ubiquity of tea exists at every passing or stationary moment. In fact, this ubiquity is the membrane containing time. Each instant is an infinitesimal unit carried within *tea*. One could say, then, that *tea* is the true God. I bow to tea. I pray at its altar. I offer sacrifices of every imaginable variety to *tea*. Tea is gracious. Tea is delicious. Let tea be praised.

      • company vision

        across the whole time i was with the company, there was talk about the dna, the vision, the values inside the company. multiple attempts were made to put that into words. a more ridiculous attempt was a workshop, and all employees should contribute, with the sum of it all being the company values.

        unsurprisingly it didn't work. company values, culture and dna come from the founders or the leadership board and they dribble down the ladder by example. this is a good way to handle it in companies that are new and not in there middle of restructuring. and finally during my parental leave, wait for it, the company founders had a workshop and there was a video about company culture and vision.

        [...]

        and now you probably feel a little bit liked i did. the essence of our company is to generate revenue by building a product that customers buy. and not a single word about how to get there, whether it's ok to cheat, pollute, gamble, threaten or lie in the process.

      • "Any resemblance to my employer is fictional"

        I've seen multiple Gemini capsules stating this when they're talking about their employers and I find it amusing. For one, why would any employer even search on Gemini? They mostly search on those highly SEO-centric websites where they can get as much data as they can on you.

        Even if they'd find a post where you just talk smack about your employer, it's not like "hey this is fictional!" would stop anyone connecting two and two. Mark the boss that likes to power trip is still the same Mark. "This Mark is not real! I promise. Just a coincidence.."

        On a more serious note, the whole "employers-stalk-you-before-employing-you" is just not a good behavior to encourage. No company or person should be preoccupied with the personal life of their employees at this level. Some really go to lengths of searching for social media accounts, if they don't find you on there you're "suspicious" which is silly for all the reasons you can think of.

    • Technical

      • Low Magic Age

        For the last few days, I’ve been playing a game called Low Magic Age (LMA). It’s a little bit roguelike, quite a bit RPG, and all together pretty charming. The game has been sitting in Early Access on Steam for quite some time, and is still there today. Usually I avoid games in this section because so many of them just wind up being abandoned, or generally don’t turn out all that great. However, LMA was on sale for about five bucks, so I thought, “Why not check it out?”

        [...]

        Of course, another big thing people look for in an RPG is loot, and there is a lot of that in LMA. Stats and abilities fixed to weapons, armor, and the like are fairly steeped in DnD conventions for the most part. There is also an MMO-inspired color coding to show the rarity of an item. On the whole, the game is pretty generous with its loot drops, sometimes even too generous. Rare items are indeed rare, but +1s, masterwork pieces, and the like drop left and right. Thankfully, inventory space is also pretty generous, so it’s hard to run out. However, players may be caught with their pants down if a particularly strong character dies in battle because there are also weight limits for inventory where the party can become overburdened. So, if a fighter or paladin, or some other character with high strength stats goes down, you may be in a situation of suddenly needing to dump a lot of heavy gear that could have turned a nice profit selling off in town.

          The answer largely depends on what your personal taste in reading is, how much you value blog spam and human based content for creations sake, informational value to storage ratio which plays into the ease of archival/sharing.

          Imagine if libraries and other such public informational repositiories had flash drives that could be loaned out containing things like wikipedia (like kiwix project does) or in our case, a sizable portion of the small net. Im sure the internet archive team could figure out a way to adapt their services to gopher+gemini, and archive a SUBSTANTIAL portion of both protocols with much greater ease than the web.

        • Adding to evenfire’s “Clickbait on Gemini” post

          Because clickbait titles — which I’m defining here as “titles that withhold important information in order to get you to click through to see the entire article” — are so common on the Internet, I usually try and get myself to stop and consider if I could rewrite the feeds’ content text to put the most important part of the post in it, saving people clicks. More often than once, I’ve rewritten a title or two to make it more useful and less like Buzzfeed house style.

          On the other hand, I tend to craft titles that make me grin, and care much less about whether they make sense or if they’re just a good vehicle for a joke or pun or a snowclone. Besides, if you’re reading the title, you’re already here.
