        Want to play some nature sounds or ambient noise on Linux? Blanket is a really good choice with a stylish user interface.

        As far as know, there are 2 good open-source applications in Linux for playing ambient sounds. They are ‘Blanket‘ who has a good design on its UI, and ‘Anoise‘ which has many more cool sounds but looks ugly.

        For Ubuntu 22.04, Fedora 36 or Arch Linux user with GNOME 42, Blanket looks more native because of the dark mode support and GTK4 + libadwaita port.

      • jmtd → log → hledger

        This year I’ve decided to bite the bullet and properly try out hledger for personal accounting. It seems I need to commit to it properly if I’m to figure out whether it will work for me or not.

        Up until now I’d been strictly separating my finances into two buckets: family and personal. I’d been using GNUCash for a couple of years for my personal finances, initially to evaluate it for use for the family, but I had not managed to adopt it for that.

        I set up a new git repository to track the ledger file, as well as a notes.txt “diary” that documents my planning around its structure and how to use it, and a import.txt which documents what account data I have imported and confirmed that the resulting balances match those reported on monthly statements.

      • Ubuntu Pit15 Practical Examples of Rsync Command in Linux

        The Rsync command allows us to transfer and sync files over an SSH connection or a local machine across different directories and machines. If you ever need to backup your directory or sync the data, the Rsync is one of the best tools for backing up the system. Using the Rsync is a lot more efficient than just copying files because Rsync only copies what is different.

        For instance, if you’re trying to backup 1000 photos, the Rsync will only choose those specific files that are either new or different since the last backup. And also, if you’re copying data and lose the network connection and re-run the Rsync command, it would know where it left off and wouldn’t have to start over.

        As a Linux sysadmin, you must know some major and practical examples of Rsync commands in Linux to make your experience smoother.

      • GamingOnLinuxYes, the Steam Deck will eventually get Ray Tracing, once the AMD GPU driver matures | GamingOnLinux

        There’s been a lot of talk lately about Ray Tracing and the Steam Deck, especially after the recent Digital Foundry video but there’s a few things that need to be cleared up.

        As a reminder: the Steam Deck runs Linux, specifically it’s SteamOS “Holo” based on Arch Linux. Right now, Ray Tracing is supported on Linux both for Native Linux titles and Windows title through Proton. NVIDIA has supported Native Vulkan Ray Tracing a long time now, and DirectX Ray Tracing (DXR) is getting into shape too with VKD3D-Proton (that translates Direct3D 12 to Vulkan) version 2.5 that was released back in October 2021 mentioning “DXR 1.0 support is more or less feature complete” and “DXR 1.1 is now experimentally exposed”.

        Do you remember the classic multiplayer shooter Soldat? Well, it continues living on with the original now being open source and the sequel just got completely remade.

        Soldat 2 entered Early Access in September 2020 but it seems it didn’t quite hit the marks players wanted, and failed to find much of an audience. Transhuman Design never gave up on it, and as it turned out they were hard at work to overhaul everything. This huge revamp is out now!

        Worms, a game I grew up with playing on the Amiga, it’s an absolute classic and some modern versions just don’t have the same charm. Thankfully, Worms 2 can be played easily on Linux (and Windows) thanks to Worms 2 Plus.

        Originally released back in 1997, it’s obviously quite dated now. Getting it running on modern systems can be quite a hassle but that’s where Worms 2 Plus comes in. The developer emailed in about it, as they’ve made sure that it nicely works with Wine too and the installer “automatically configures the game for Wine” they tell me, and this is a perfect way for Wine to shine.

      • GamingOnLinuxScreeps: Arena is an online RTS for programming fans | GamingOnLinux

        Do you love programming? How about real-time strategy games? Check out the new Native Linux release of Screeps: Arena. This is the second game in the series, with the first being Screeps: World that was released back in 2016 and gained a positive rating (and still has players too).

        While Screeps: World was a persistent MMO, Screeps: Arena brings things down to be more like a traditional RTS that might end up appealing to a much wider variety of players. It’s online only and PvP, where your scripts fight off against others autonomously. Actually sounds quite fun, if you enjoying writing a few lines first.

      • GamingOnLinuxValve updates Portal to improve Steam Deck performance | GamingOnLinux

        Valve sure do give a lot of love to their games (okay, most, I hear the rumbling of TF2 fans in the background) and a new update has rolled out for the original Portal to help the Steam Deck.

        Portal is one of the titles that Valve updated with DXVK-Native, which allows the classic to run using Vulkan instead of OpenGL, an update for this title I somehow missed from back in late February. They did the same for Portal 2, Left 4 Dead 2 and the Half-Life 2 series. The problem with DXVK for both Native Linux titles and Windows games in Proton, is that it can stutter while it builds up a shader cache.

      • GamingOnLinuxOnline co-op shooter GTFO adds ‘partial’ Steam Deck support | GamingOnLinux

        GTFO, the scary online co-op shooter from 10 Chambers recently had another update, and with it the developers claim they added in “partial” support for the Steam Deck.

        What is it? “GTFO is an extreme cooperative horror shooter that throws you from gripping suspense to explosive action in a heartbeat. Stealth, strategy, and teamwork are necessary to survive in your deadly, underground prison. Work together or die together” — according to the developer.

        A title that already ran reasonably well on Linux desktops with Proton. For the Steam Deck though it’s currently rated as “Playable”, and when I quizzed them a little more one of their team said it works better now with the “virtual keyboard, among some other things” as they work to make it Verified. Small steps but certainly better than nothing.

          Later on, a kind individual helped testing and debugging the Stream Deck Original (v1) code. I only have a 2nd generation Original, and the HID protocol changed significantly between them, so this testing was invaluable. There were another couple of bugs specific to Original v1 fixed in no time after they were reported.

          Because Stream Deck Original (v2), XL, and MK.2 seem to share the same HID protocol, I’m cautiously confident that they all should be fine.

          Ubuntu is one of the best Linux distributions that we can find on the net. This is an excellent gateway for all those users who have not tried any Linux distribution before, and a robust, stable system that is faithful to the Linux philosophy for those who are more demanding. Canonical, the company responsible for the development of this OS, usually releases two (controversial) updates a year for this distro. And now it is the turn of the first update of 2022: discover the new Ubuntu 22.04 “Jammy Jellyfish” .

          Every 6 months, Canonical releases a new version of Ubuntu in which, in general, it usually updates its packages and includes a new Kernel. These updates have a general support of 9 months, which requires, yes or yes, to update the system at least twice a year. Unless we choose to install an LTS version. These stand out for having a 5-year support, and Canonical releases a new LTS every 2 years. That is, after three normal updates, the fourth is back to LTS.

          After the release of Ubuntu 20.04, the last LTS to date, three updates of this distro have already arrived: 20.10, 21.04 and 21.10. Therefore, the new version 22.04 is once again an LTS. It is time to update our systems again.

          The flux capacitor is one of the most iconic movie props of all time. Part of that is due to its plot purpose in the Back to the Future franchise, but its fame is also because it looked so futuristic when the first movie hit theaters in 1985. LEDs were still relatively new in the public consciousness at the time and the animated LED effects in the prop flux capacitor were attention getting. If you want to reproduce that effect, element14 Presents’ Derek Brodeur has a video showing you have to drive flux capacitor-style LEDs with an Arduino.

          The experienced among you know that this effect is possible to achieve with discrete components, which is likely how the original prop worked. But it is easier to reproduce the “animation” using a modern microcontroller like the Microchip ATmega4809 found on the Nano Every board. By driving each LED via PWM (pulse-width modulation), you can control its brightness. PWM works by very quickly modulating power to LED, with proportion of “on” time resulting in perceived brightness.

          With the Earth’s population still on track to increase by another two billion people by the year 2050, finding ways to feed them without causing grave harm to the environment is a top priority. Currently, fish is one of the most widely consumed foods in the world, and a new technology called biofloc helps provide both a food source and environmental stabilizer to fishponds without the need for dangerous chemicals/processes.

          As part of element14’s Just Encase Design Challenge, Md. Khairul Taifur had the idea to create a device that could sit within a pond and report detailed telemetry for environmental markers, as well as correct minor water quality issues via the use of a heater and water pump. His system is based around a MKR WAN 1300, which is responsible for collecting data from each sensor and then sending it to the cloud with its onboard LoRaWAN module. To make the system independent from an external power source, Taifur included a small 5V solar panel, power management board, and rechargeable battery pack.

      • Thoughts dereferenced from the scratchpad noise. | Open Source Firmware on TigerLake platforms – part 1

        If somebody would tell 7 years ago that Intel will support open source firmware, he would be laughed at instantly. If we recall time, like 15 years ago where the datasheets were more open and were sufficient to write open source firmware, today it is not possible. Silicon vendors are hiding the intellectual property contained in the processors. It would seem like the open source firmware is doomed, but…

        Thankfully there are companies and Intel employees that try to make impact and change this situation. For example Google supporting the coreboot project on their Chromebooks encourage Intel to release the Firmware Support Package (FSP). The FSP is a bundled silicon initialization code in a binary form with well documented interface and configuration options. It simplifies new hardware enabling and reduces cost of overall firmware development. While it doesn’t solve all problems and sometimes causes issues, kudos should go to Intel for supporting the open source firmware. Special credits should go to the open source firmware community members from Intel: Nathaniel DeSimone, Vincent Zimmer, Brian Richardson and Isaac Oram.

            The idea of “soft-errors”, particularly “single-event upsets” often comes up when we have strange errors in telemetry. Single-event upsets are defined as: “a change of state caused by one single ionizing particle (ions, electrons, photons…) striking a sensitive node in a micro-electronic device, such as in a microprocessor, semiconductor memory, or power transistors. The state change is a result of the free charge created by ionization in or close to an important node of a logic element (e.g. memory “bit”)”. And what exactly causes these single-event upsets? Well, from the same Wikipedia article: “Terrestrial SEU arise due to cosmic particles colliding with atoms in the atmosphere, creating cascades or showers of neutrons and protons, which in turn may interact with electronic circuits”. In other words, energy from space can affect your computer and turn a 1 into a 0 or vice versa.

            We’re pleased to announce that we have partnered with the Center for Humane Technology, a nonprofit organization that radically reimagines the digital infrastructure. Its mission is to drive a comprehensive shift toward humane technology that supports the collective well-being, democracy and shared information environment. Many of you may remember the Center for Humane Tech from the Netflix documentary ‘Social Dilemma’, solidifying the saying “If you’re not paying for the product, then you are the product”. The Social Dilemma, is all about the dark side of technology, focusing on the individual and societal impact of algorithms.

            It’s no surprise that this decision to partner was a no brainer and supports our efforts for a safe and open web that is accessible and joyful for all. Many people do not understand how AI and algorithms regularly touch our lives and feel powerless in the face of these systems. We are dedicated to making sure the public understands that we can and must have a say in when machines are used to make important decisions – and shape how those decisions are made.

          On 26 January 2022, the European Commission presented its proposal for the EU Declaration on Digital Rights and Principles which will serve as a reference point in the future and as a common EU vision of our digital rights. The declaration is now being discussed in the European Parliament and Council, and Free Software should become part of it.

          Built on the Berlin and Tallinn declarations, this proposal aims to lay the groundwork for a consistent framework that will serve as a guideline and a reference point for the ongoing and future digital transformation of Europe. These aforementioned declarations already refer to Free Software (“Open Source” in their text) when it comes to digital sovereignty and interoperability, while they also demand more use of “Open Source” and strengthening the requirement for its use.

    • Standards/Consortia

      • Gemtext and Image

        One of the most noticeable things about Gemini is that it is text-based. Sure, it can support images but, depending on the client, these are mostly left ‘hidden’. Gemini gains a lot of its ‘identity’ from this emphasis on text. One of the first things you’ll notice if you compare an average web page and a page on Gemini is that one is filled with images and highly ‘visual’, while the other is just a wall of text.

        Does this mean, then, that gemtext is somehow anti-image? That it is some new, iconoclastic medium which attempts to break free from the ‘seduction’ of images on the web? In some ways, yes, but in my experience browsing Gemini, it’s not as simple as that.

      • Quick thoughts on Lemmy

        I’ll jot down some quick thoughts on Lemmy, a Reddit-like service for the Fediverse. When it first was announced a few years ago, I thought “yeah, right, it has a really long way to go” and instead of helping I just sorted it under “vaporware”. But now it’s becoming usable♥.

        It’s centralized, and federated.

        Every community is tightly tied to one server (while there are several servers, each have their own communities). So there’s not a lot you gain compared to something like a lobste.rs server or a Discourse server or a mailing list or other traditional forum softwares and bulletin boards. Each community is still centralized. (And you also get to keep some of the simplicity of that approach, but only some, because this is still Fedi in all its clunky glory.)

        Unlike Discourse, you can post from an account from another server (sort of like with Open ID back in the blog era). This means from other Lemmy servers but also from other ActivityPub implementations. (It’s a “subset with extensions” so you might have to square peg it a bit.) You can also then receive replies and notifications on that home server, which is convenient and cozy. (On the other hand, some of these forum servers have mailing list modes which are convenient and cozy in their own way.)

        It is also similar to Guppe in many ways. You can follow communities and it boosts posts from those communities into your timeline, and you can post to the community too. Compared to Guppe, there is moderation and group ownership, and there’s an optional Reddit-like web frontend. One way I like to use it is to browse the web frontend and then when I wanna reply, I dig up the post via Fedi and reply from there. A few extra hoops, but then I’ll see any replies from the comforts of my own home.

      • Facebook’s Ukraine-Russia Moderation Double Standard

        AN UNPRECEDENTED SPREE of policy changes and carveouts aimed at protecting Ukrainian civilians from Facebook’s censorship systems has earned praise from human rights groups and free expression advocates. But a new open letter addressed to Facebook and its social media rivals questions why these companies seem to care far more about some attempts to resist foreign invasion than others.

        In response to the Russian invasion of Ukraine, Meta Platforms, which owns Facebook and Instagram, rapidly changed its typically strict speech rules in order to exempt a variety of posts that would have otherwise been deleted for violating the company’s prohibition against hate speech and violent incitement.

        Internal Meta materials reviewed by The Intercept show that in early March the company temporarily enacted an exception to its hate speech policy permitting Facebook and Instagram users in Ukraine to call for the “explicit removal [of] Russians from Ukraine and Belarus,” posts that would have otherwise been deleted for violating the company’s ban on calling for the “exclusion or segregation” of people based on their national origin. The rule change, previously reported by the New York Times, was part of a broader package of carveouts that included a rare dispensation to call for the death of Russian President Vladimir Putin, use dehumanizing language against Russian soldiers, and praise the notorious Azov Battalion of the Ukrainian National Guard, previously banned from the platform due to its neo-Nazi ideology.

          • Open Source InitiativeLet’s get open source voices heard by the EU on standards essential patents [Ed: Software patents article in OSI site... by Simon Phipps, for a change]

            Now is a crucial time for the open source community to respond to the consultation launched by the European Commission on standards essential patents (SEPs). The Commission is proposing the creation of a new framework governing their use. Since this has been directed at the existing SEP-reliant industries where open source is less common, we want to be sure the voices of the open source community are heard in this public consultation.

            It’s easy to misunderstand SEPs as implying that patents are essential to all standards; they are not! It is OSI’s position that many standards do not involve SEPs, that open source requires restriction-free licensing if the creators of a standard hold essential patents, and that the EU needs to harmonize its open source and standards strategies. OSI’s formal response to this Call for Evidence is forthcoming.

            This public consultation came about because some standards users have found the current system for licensing SEPs has issues with transparency, predictability and efficiency. In some cases it also offers incumbents undue market control, especially over market entry. Under the current approach, patent-holders commit to license their SEPs – patents known to be inherent to implementation of a standard – to users of the standard on fair, reasonable and non-discriminatory (FRAND) terms and conditions.

        • Public Domain Review*Ostentatio Genitalium* in Renaissance Art – The Public Domain Review

          Ostentatio genitalium (the display of the genitals) refers to disparate traditions in Renaissance visual culture of attributing formal, thematic, and theological significance to the penis of Jesus. That these images seem to have been created in good faith, with pious intentions, mystifies art historians, and many refuse to recognize the category as noteworthy or distinct from the nudity of angels and putti. Yet, as examples accrue, the conspicuous attention lent to Christ’s phallus cannot escape even the most disinterested gaze. “It is no exaggeration to say that this has probably been the most taboo topic in Christian thought for two thousand years”, writes Stephen Sapp. In contrast to classical sculptural conventions, which — with exceptions like certain herma and statues of satyrs — often showcase male genitalia in a state of flaccid modesty (akin to Michelangelo’s Risen Christ), these Renaissance images shock us because they are so frequently ithyphallic: Christ has risen, but not in the way we have come to expect.
          Beginning around 1260 and enjoying widespread employment before finally tapering off in the seventeenth-century, ostentatio genitalium reversed a Byzantine tendency to depict Christ as sexless, his missing organs covered by flat, diaphanous veils. This was a symbol of purity and perfection, following from Augustinian notions that untimely erections are reminders of Adam’s “sin of disobedience”. Yet in the ostentatio genitalium tradition the opposite seems true: it is the visual virility of Christ that affirms his divinity. The natural question to ask, after blinking our eyes, would be why? How do practitioners of a religion, whose seven heavenly virtues include prudence and temperance, decide to venerate, for centuries, an apparently prurient vision of their savior?
