      • Best Free and Open Source Alternatives to Microsoft SwiftKey - LinuxLinks

        Microsoft’s stance for decades was that community creation and sharing of communal code (later to be known as free and open source software) represented a direct attack on their business. Their battle with Linux stretches back many years. Back in 2001, former Microsoft CEO Steve Ballmer famously tarnished Linux “a cancer that attaches itself in an intellectual property sense to everything it touches”. Microsoft also initiated its “Get the Facts” marketing campaign from mid-2003, which specifically criticized Linux server usage, total cost of ownership, security, indemnification and reliability. The campaign was widely criticized for spreading misinformation.

        However, in recent years, there has been a partial shift by Microsoft to embrace the open source software paradigm. For example, some of their code is open sourced. Examples include Visual Studio Code, .NET Framework, Atom, and PowerShell. They have also made investments in Linux development, server technology and organizations including the Linux Foundation and Open Source Initiative. They have made acquisitions such as Xamarin to help mobile app development, and GitHub a hugely popular code repository for open source developers. And they have partnered with Canonical, the developers of the popular Ubuntu distro. But many developers remain hugely sceptical about Microsoft and their apparent shift to embrace open source.

      • 3 steps to start running containers today | Opensource.com

        Whether you're interested in them as part of your job, for future job opportunities, or just out of interest in new technology, containers can seem pretty overwhelming to even an experienced systems administrator. So how do you actually get started with containers? And what's the path from containers to Kubernetes? Also, why is there a path from one to the other at all? As you might expect, the best place to start is the beginning.

        [...]

        You've created two containers, and you've run them in a pod. You know enough now to run services in containers on your own server. If you want to move to the cloud, containers are, of course, well-suited for that. With tools like Kubernetes and OpenShift, you can automate the process of launching containers and pods on a cluster.

      • Going IPv6 only

        Since we're slowly coming up to 25 years of having IPv6, but still not actually having IPv6, I tried making a seperate local network that only has v6 access. In theory quite a few of the popular internet services should have IPv6 connectivity working.

        From previous network configuration mistakes, I've learned that it takes quite a while before I notice the loss of IPv4 connectivity if IPv6 is still working. Usually, I notice that by having the search engine work perfectly fine, but none of the websites I click loading.

      • Ryujinx: Great Strides With Vulkan - Boiling Steam

        Nintendo Switch emulation, as great as it has already been, is getting even more spectacular. Today, the progress report for Ryujinx — one of the Nintendo Switch emulators available on Linux/PC — has been released for the month of January. But don’t let me do all the talking; just look at this clip for a few moments:

        This clip was posted as part of their blog post. This, right here, is a comparison between GLSL, the shader language for OpenGL, and SPIR-V, the shader language for Vulkan. The difference is night and day. Observe how much more quickly the game caches shaders on SPIR-V. And also notice that SPIR-V is only using a single thread, rather than GLSL’s multi-threaded processor usage.

        • Why I love KDE for my Linux desktop

          One of the things that open source prides itself on is choice. You don't have to settle for anything you don't love. You can change your file manager, your text editor, and you even have over 24 desktops to choose from. As with many Linux users, I was pretty flexible about the desktop I used at first. I didn't know what I liked at first, because I hadn't tried everything available to me. On one auspicious day in January 2008, KDE 4.0 was released, and from the moment I laid eyes upon the Plasma Desktop, I knew that it was the Linux desktop I'd been waiting for (and having only been a Linux user for a year by that time, I guess I didn't have to wait long). Even though I have and enjoy GNOME on my laptop, Fluxbox on my Pi, and probably a few other combinations, I consider myself a Plasma Desktop user, and a member of the KDE community.

        • Review: Running guest distributions with Distrobox

          My trial with Distrobox got off to a rough start and it was mostly due to a lack of documentation. The project has a quick-start guide, some examples on installing fresh guests, and entering the guest containers. However, the documentation hasn't been fleshed out. I couldn't find anything on installing dependencies, dealing with permission issues, finding a list of supported guest distributions, or stopping containers. Hopefully these items will get added later.

          As it stands, I spent most of my trial trouble-shooting issues which involved getting Distrobox installed, getting its dependencies running, and trying to figure out which Linux distributions I could install through Distrobox.

          Once these issues were resolved I found using the software quite enjoyable. I liked being able to quickly install an Arch or Fedora container, experiment with it, mess it up, and then delete it - all within a few minutes. I like being able to start up a container and run a few programs without the overhead or headaches of a full virtual machine. I liked how easily guest programs, even desktop applications, integrated into the host environment.

          The whole experience was very similar to my trial with JuNest last year. The setup of JuNest was a little more straightforward, but it required more trouble-shooting for some guest applications once it was up and running. JuNest also focuses exclusively on running Arch environments while Distrobox should be able to run virtually any distribution as a guest.

          All in all, I think Distrobox is worth checking out, especially if you find yourself wanting to experiment with new versions of software or run packages not available on your host system.

          Since the onset of the COVID-19 pandemic, no topic has impacted enterprises more than digital transformation. While many marveled at the rapid rate of change in early 2020 – most frequently citing McKinsey’s report that organizations advanced their digitalization by four years in a span of just six months – the sustained emphasis on digital transformation continues to shape the ways in which enterprises approach today’s business challenges.

          While 2022 could see a broader return to normalcy than in 2020 or 2021, many organizations are preparing for a future that maintains and expands on the changes made to fully digitize their infrastructure and processes. In an always-online world, and with new technologies like web3 and the metaverse promising future changes to the way we work, enterprises must double down on their digital transformation initiatives to ensure they remain at the head of the pack.

          From “traditional” IT positions (such as software developer, system administrator, or security analyst) to more recent titles like DevOps engineer, cloud platform engineer, or site reliability engineer (SRE), automation skills are relevant – and often required – in a great many tech roles today.

          So if you’re looking to bolster your appeal on the IT job market, building automation skills is certainly a good way to do it. Automation chops have the added bonus of portability: If you don’t want to be pigeonholed into a particular title or function, automation practices and technologies may pave the way into other roles down the line, too.

Generally, here we refer to the drivers that we install in the operating system and that help to communicate both elements. A sound card , mouse, printer or webcam will always work better with a correctly updated driver and if it is from its manufacturer, the better.

        Today we’re going to be using the new Kywoo3D Tycoon Slim 3D printer to print two new cases for my Raspberry Pis. I’ll be printing one in regular PLA to get an idea of the print quality that the Tycoon Slim can achieve and one in TPU, which is a flexible filament that is perfect for creating bump and drop resistant cases – but is also notoriously difficult to print with. The TPU version will be especially useful for Pi’s that you’re going to use for travelling, like a portable media server or NAS.

        This 3D printer was sent to me to try out and share with you by Kywoo3D through the online 3D printing store Tinker Hive. Tinker Hive is an authorised re-seller of Kywoo3D products and they offer three payment options, with the option to pay your printer off in four interest-free instalments, making it more affordable for tinkerers to get into 3D printing.

        Kywoo3D is a relatively new company to the 3D printing game, having successfully launched their Tycoon 3D printer on Kickstarter in April last year. They’ve now brought out a more compact, and cheaper version called the Tycoon Slim, and that’s what we’re going to be taking a look at and using for today’s prints.

            release notes:
            
            

            Gearing up for a Trip Log series to port a small program from Guile-SDL to Guile-SDL2:

            https://dthompson.us/projects/guile-sdl2.html

            Volunteers familiar w/ Guile-SDL2 welcome!

            README excerpt:

            Guile-SDL is a set of modules that provide bindings for various Simple DirectMedia Layer (http://www.libsdl.org) libraries.

            Most of the SDL functions are wrapped, with the exception of a few functions that are too C-centric. The SDL threads, audio and network functions are not included. However, there are (optionally configured) bindings for SDL_mixer and SDL_ttf.

            Also included is SDL_gfx 2.0.26 (by Andreas Schiffler) source code (ZLIB license) and bindings for it.

            This is alpha code (pre 1.0 release), tested with various, but not all, versions of Guile and SDL. It may have bugs, and the interfaces may change from version to version.

            NEWS for 0.6.1 (2022-02-20):

            - changes to ‘(sdl misc-utils)’

            - new proc: ‘create-rgba-surface’

            This returns a new 32bpp surface of the specified width and height w/ the ‘src-alpha’ flag set.

            - new proc: ‘create-rgba-square’

            This returns a new 32bpp square surface of the specified edge length w/ the ‘src-alpha’ flag set.

            - ‘rotate-square’ fixed / extended

            Previously, this proc made reference to ‘roto-zoom-surface’ in the wrong module. This undefined reference was never detected, showing how middlig to poor the test coverage was (and remains). Now, ‘roto-zoom-surface’ is properly imported from ‘(sdl gfx)’.

            Another oddity is that previously, the specified ANGLE argument was subtracted by 90 prior to passing it to ‘roto-zoom-surface’. This bizarre practice is no more.

            Re extension, ‘rotate-square’ now takes optional 3rd arg MKSQUARE which specifies a procedure to make a new square surface. If omitted, it defaults to ‘create-rgba-square’.

            Additionally, if the rotated surface has flag ‘src-alpha’ set, the resizing blit uses ‘(sdl gfx) blit-rgba’ to do the job (otherwise ‘(sdl sdl) blit-surface’, as before).

          This is the fourth year I’m teaching my D Programming Language course at a very real university in Russia. It’s a full-term course with lectures, practical lessons, and exams, although it’s all remote now. This is the story about how I got there, the challenges I encountered, and how students sometimes surpass their teachers.

      • Opinion | Teaching and Learning Through a Pandemic

        Last week the Los Angeles Times reported that half of California students did not meet standards in Math and reading and, no one should care. The state shouldn’t care, the county shouldn’t care, the districts shouldn’t care, the schools shouldn’t care, the teachers shouldn’t care, the parents shouldn’t care, and most of all the students shouldn’t care. What they all should do instead is understand. They should all have a critical consciousness and have an awareness about what is happening in homes, schools, and communities, nation and worldwide. Research shows that tests being cited are meaningless measures of anything other than social class and familiar economic wealth. Regardless of that direction we hold fiercely to the notion that tests matter. They do not.

      • Intel Optane: A Restrictive Licensing Model and the Half Billion Dollar Operating Loss in 2020

        I have written about this technology before. It isn’t anything new. Now, a little over a week ago, it was revealed that in the year 2020, Intel had reported a half-billion dollar loss on its Optane 3D XPoint business. Yikes! Also, Intel’s Optane head left the company.

        [...]

        The future may not be looking good for the technology. At least, not in the near term.

        Anyway, circling back to the original comment regarding the large negative financial impact, I personally feel that the root of this problem comes from the fact that the technology is manufactured and distributed under a very restrictive licencing model.

      • Top chipmakers ignore India’s semiconductor subsidies ● The Register

        India has revealed the identities of companies that have applied to build semiconductor manufacturing facilities on its soil under a $10 billion subsidy scheme – and none are substantial chipmakers.

        As The Register reported last week, a consortium of Taiwan's Foxconn and Indian firm Vedanta committed to build a plant under the scheme, despite neither company having any previous experience in the field. Now India's government has announced another two bidders: Singapore's IGSS Ventures and an outfit called ISMC.

        IGSS operates an eight-inch CMOS foundry through its CompoundTek brand, which focuses on silicon photonics. ISMC is backed by a company called Next Orbit Ventures, and already had plans to build a fab in India.

        The government says the three applications it has received will build product on processes ranging from 28nm to 65nm, and have collective output of 120,00 wafers each month.

      • Immersive Stereo Sound Recording With This Binaural Microphone | Hackaday

        Sound recording has been a consumer technology for so long now that it is ubiquitous, reaching for a mobile device and firing up an app takes only an instant. Anyone who takes an interest in audio recording further will find that while it’s relatively straightforward to make simple recordings. But, as those among you who have fashioned a pair of Shure SM58s into an X configuration with gaffer tape will know, it can be challenging to create a stereo image when recording outside the studio. In the quest to perfect this, [Kevin Loughin] has created a binaural microphone, which simulates a human head with microphones placed as ears to produce ambient recordings with an almost-immersive stereo image.

        [...]

        The results as you can hear in the video below the break are impressive, certainly so for the cost. It’s not the first such microphone we’ve shown you, compare it with one using a foam-only head.

      • The USB-C Connectors You Never Knew You Wanted To Avoid | Hackaday

        On Tech Twitter, some people are known for Their Thing – for example, [A13 (@sad_electronics)], (when they’re not busy designing electronics), searches the net to find outstanding parts to marvel at. A good portion of the parts that they find are outstanding for all the wrong reasons. Today, that’s a through-hole two-pin USB Type-C socket. Observing the cheap tech we get from China (or the UK!), you might conclude that two 5.1K pulldown resistors are very hard to add to a product – this socket makes it literally impossible.

        We’ve seen two-pin THT MicroUSB sockets before, sometimes used for hobbyist kits. This one, however, goes against the main requirement of Type-C connectors – sink (Type-C-powered) devices having pulldowns on CC pins, and source devices (PSUs and host ports) having pull up resistors to VBUS. As disassembly shows, this connector has neither of these nor the capability for you to add anything, as the CC pins are physically not present. If you use this port to make a USB-C-powered device, a Type-C-compliant PSU will not give it power. If you try to make a Type-C PSU with it, a compliant device shall (rightfully!) refuse to charge from it. The only thing this port is good for is when a device using it is bundled with a USB-A to USB-C cable – actively setting back whatever progress Type-C connectors managed to make.

      • A Ball Lens For Optical Fiber Coupling On The Cheap | Hackaday

        It’s fair to say that for most of us, using a fiber optic cable for digital audio or maybe networking will involve the use of an off-the-shelf termination. We snap the cable into the receptacle, and off we go. We know that inside there will be an LED and some lenses, but that’s it. [TedYapo] though has gone a little further into the realm of fibers, by building his own termination. Faced with the relatively high cost of the ball lenses used to focus light from an LED into the end of the fiber he started looking outside the box. He discovered that spherical glass anti-bumping balls used when boiling fluids in laboratories make an acceptable and much cheaper alternative.

        Investigators have identified a Black student is responsible for racist graffiti found over a water fountain at C.K. McClatchy High School with a message that alluded to segregation, community leaders announced Thursday.

        Mark Harris, a community liaison with Sacramento City Unified School District, said the student confessed to writing “colored” on one side of the dual water fountain and “white” on the other side. He said he saw video that showed the student writing the graffiti that corroborates her confession.

        • Ethiopia starts generating power from River Nile dam

          Ethiopia has been diverting Nile water to fill a vast reservoir behind the dam.

          Egypt, which lies downstream and depends almost completely on the Nile for its irrigation and drinking water, is worried this will affect the levels of water flowing into the country.

          It therefore wants a guarantee of a certain of volume of water coming into Egypt.

        • Ethiopia's Abiy inaugurates electricity production at Nile mega-dam

          The project has raised tensions with Egypt, an arid nation of nearly 100 million people, depends on the Nile for most of its water needs, including for agriculture.

          Cairo claims a historic right to the river dating from a 1929 treaty between Egypt and Sudan, represented by colonial power Britain, that gave Egypt veto power over construction projects along the river.

          A 1959 treaty boosted Egypt's allocation to around 66 percent of the river's flow, with 22 percent for Sudan.

          Ethiopia was not party to those treaties and does not see them as valid.

        • Ethiopia starts generating electricity at controversial Nile dam

          The 145-metre high dam lies on Blue Nile River in the Benishangul-Gumuz region of western Ethiopia, not far from the border with Sudan.

          Egypt, which depends on the Nile for about 97 percent of its irrigation and drinking water, sees the dam as an existential threat.

        • Ethiopia Starts Partial Power Generation From Blue Nile Dam

          The dam, which will have a total power generating capacity of 6,500 megawatts, has been a source of tensions between Ethiopia and the other riparian states, Sudan and Egypt. Ethiopia has already conducted two fillings of the dam, but the speed at which it will be filled and the amount of water that will be released during drought seasons remains unsolved.

          Egypt fears a quick filling of the dam will reduce its share of Nile waters and seeks a binding legal agreement in case of a dispute.

        • Sudan stresses need for binding solution to Ethiopia's Nile dam issue

          The meeting stressed the need to reach a legal and binding solution under the patronage of the African Union (AU) in a manner that preserves Sudan's interests and its water rights, the statement noted.

In other words, resistance is futile.

      • Kazakhstan's Internet Shutdowns Could Be a Warning for Ukraine - The New York Times

        As Almaty, Kazakhstan’s largest city, spiraled into chaos last month over rising energy costs and anger at the government, the country’s leaders took a drastic step to quell protests: They blocked the internet.

        First, they tried to ban access to some news sites, social networks and messaging services. Then, as activists bypassed those curbs with software that masked their locations, the authorities shut down almost all connectivity in the country.

        The moves added uncertainty to an already dire situation. After payment apps and point-of-sale machines used to swipe debit cards went down, lengthy lines formed at A.T.M.s as Kazakhs rushed to get cash. Families could not communicate with loved ones. Taxi drivers who relied on ride-hailing apps said they stopped driving because they could not connect with passengers.

        “It was impossible to communicate,” said Darkhan Sharipov, 32, an accountant who was part of the protests. “The lack of information multiplied the chaos and disinformation.” The scenes in Kazakhstan offer a preview of what may unfold in Ukraine, where the internet could be one of the first targets of the Russian military in a potential conflict. Ukrainian and Western officials have warned that cyberassaults could be part of any Russian intrusion.

      • India’s war on the internet

        In it, IFF highlighted that internet shutdowns are extremely common in India, citing reports by Top10VPN and Access Now, and data from the Software Freedom Law Center and Meta.

        According to the TopVPN report, the Indian government imposed major internet restrictions on citizens for 1,157 hours in 2021, the equivalent of more than 48 days. This included 317.5 hours of total internet blackout and 840 hours of bandwidth throttling.

        In all, internet restrictions cost the Indian economy $582.8 million (Rs 4,348 crore) in 2021. Only Myanmar ($2.8 billion) and Nigeria ($1.5 billion) did more economic damage with these self-inflicted wounds.

        This dismal performance was actually an improvement for India from 2020, when it lost an estimated $2.8 billion – more than any other country by far – after shutting down the internet for a combined 8,927 hours.

        Overall, government internet outages in 21 countries lasting over 30,000 hours cost the global economy $5.45 billion in 2021, a 36% increase from 2020, when $4.01 billion was lost, the report said.

      • What's next for the EU's DSA? - Access Now

        The Parliament also resisted the push to include a so-called media exemption from these rules — a dangerous provision that would give content by media publishers privileged treatment and thereby foster the spread of disinformation online. As negotiations over the final shape of the DSA continue, it is essential that Parliament defends this solid position with potential to empower users, instead of allowing the private sector to continue escaping transparency and accountability.

        To those outside the “Brussels bubble” the Parliament vote on the DSA might look like the end of the lawmaking process. In reality, we still have a road ahead before we see the final text.

        Below, we explain where we are in the DSA negotiations and what is coming next. We also highlight how the positions of the three main negotiators — the European Parliament, the Council of the European Union, and the European Commission — differ, providing hints as to what to expect.

Surprisingly, Watch Tower is pressing ahead with its copyright lawsuit regardless.
