      • Johan Thelin: Debian on the XPS13 Plus (9320) - Life of a Developer

        Still no sound, but I learned a couple of new things…

        So, I finally got around to upgrading my laptop. I decided to go for my fourth XPS13, and this time I opted for a maxed out XPS13 Plus. A really nice machine. However, the driver stack isn’t quite there yet. Yes, I should have read up more before buying, but I didn’t and I know it will be sorted out over time.

        As a vim user, the touch Esc key will be a challenge. Perhaps this is where I learn to bind to capslock, but I’ve not come to that point yet.

        So, after installing using the netinst image with non-free drivers (and my phone over USB tether for networking since the wifi still didn’t work), I had to move to testing for anything to work. Then I installed firmware-iwlwifi, iwlwifi and firmware-sof-signed from non-free. This got me into a graphical desktop and most things work (I could configure the touch pad for tap-to-click, and so on). I run a KDE desktop, so I installed some Plymouth stuff, breeze for SDDM and such, but that shouldn’t affect the issues described here.

      • Kubernetes BlogKubernetes 1.26: We're now signing our binary release artifacts! | Kubernetes

        The Kubernetes Special Interest Group (SIG) Release is proud to announce that we are digitally signing all release artifacts, and that this aspect of Kubernetes has now reached beta.

        Signing artifacts provides end users a chance to verify the integrity of the downloaded resource. It allows to mitigate man-in-the-middle attacks directly on the client side and therefore ensures the trustfulness of the remote serving the artifacts. The overall goal of out past work was to define the used tooling for signing all Kubernetes related artifacts as well as providing a standard signing process for related projects (for example for those in kubernetes-sigs).

        We already signed all officially released container images (from Kubernetes v1.24 onwards). Image signing was alpha for v1.24 and v1.25. For v1.26, we've added all binary artifacts to the signing process as well! This means that now all client, server and source tarballs, binary artifacts, Software Bills of Material (SBOMs) as well as the build provenance will be signed using cosign. Technically speaking, we now ship additional *.sig (signature) and *.cert (certificate) files side by side to the artifacts for verifying their integrity.

        The 60th edition of the Top500 list, revealed today at SC22 in Dallas, Texas, showcases many of the same systems as the previous installment, with Frontier still out in front as the first official Linpack exascaler, clocking 1.102 exaflops. Installed at Oak Ridge National Laboratory, Frontier – a collaboration of the DOE, HPE and AMD – comprises 74 HPE Cray EX cabinets, housing 9,408 nodes, each equipped with one AMD Milan “Trento” Epyc CPU and four AMD Instinct MI250X GPUs.

        Frontier also scored highest on the HPL-MxP benchmark with 7.9 exaflops. A companion benchmark to the Top500, HPL-MxP was formerly known as HPL-AI. The benchmark “seeks to highlight the convergence of HPC and artificial intelligence (AI) workloads based on machine learning and deep learning by solving a system of linear equations using novel, mixed-precision algorithms that exploit modern hardware,” according to the backers.

      • 9to5LinuxLinux Kernel 6.1 LTS Released with Initial Support for the Rust Programming Language

        More than two months in the works, Linux kernel 6.1 is here to introduce experimental support for the Rust programming language. While this may sound very exciting for some, you should keep in mind that "experimental" means that it’s only a very basic implementation of Rust that cannot be used for any real-world use cases.

        Another major change in Linux 6.1 is the multi-generational LRU VM work to better identify the memory pages that are actually in use. In addition, the new kernel series brings the ability to perform PKCS#7 signature verifications in BPF programs and to create destructive BPF programs, and a new security-module hook for controlling how user namespaces are created.

      • Linux mailing listsLinux 6.1
        So here we are, a week late, but last week was nice and slow, and I'm
        much happier about the state of 6.1 than I was a couple of weeks ago
        when things didn't seem to be slowing down.
        
        

        Of course, that means that now we have the merge window from hell, just before the holidays, with me having some pre-holiday travel coming up too. So while delaying things for a week was the right thing to do, it does make the timing for the 6.2 merge window awkward.

        That said, I'm happy to report that people seem to have taken that to heart, and I already have two dozen pull requests pending for tomorrow in my inbox. And hopefully I'll get another batch overnight, so that I can try to really get as much of the merge window done with early. We all want to have a calm holiday season.

        And because of that "we all want to have a calm holiday season", I want to re-iterate that I'm going to be pretty strict about the merge window rules. The rules are that the pull requests sent to me during the merge window should have been ready _before_ the merge window, and have seen some time in linux-next. No last-minute batch of experimental new development that hasn't been seen by our test automation.

        So to make my life easier, I will just drop any pull requests that come in late, or that look like they haven't been in linux-next. This time of year, we're all going to be much happier to deal with the stress of the season _without_ having to deal with the stress of any late development. So if you already realize that work hasn't been in linux-next, let's just all agree to not even send me the pull request at all, and we'll all be happy with the calm end-of-the-year season. Ok?

        Anyway, I think I've harped on that enough, let's just enjoy this release and the upcoming festivities. As can be seen from the shortlog below, last week really was very quiet, and it's mainly a few last-minute fixes mostly dominated by drivers (networking in particular, but there's some media, HID and GPU noise in there too).

      • SlashdotLinux Kernel Fixes Longstanding Bug in Its Handling of Floppy Disks - Slashdot

        This isn't the only such fix in recent years. As a series of articles on Phoronix details, there has been a slow but steady flow of fixes for the kernel's handling of floppy drives since at least kernel 5.17, as The Register mentioned when it came out....

        Back in July 2016, SUSE kernel developer Jiri Kosina submitted a patch. The problem arose because this change broke something else and later got reverted, and so the problem hung around. In July last year, he sent in a new patch that fixed it again for the 5.12 kernel, and was later back-ported to 5.10, an LTS version, and again into kernel 5.15 — another an LTS version, and the one you're running today if you're on the current Ubuntu LTS release, or something built from it such as Linux Mint 21....

        Now, in December 2022, a new patch for the forthcoming kernel 6.2 fixes a memory leak that dates back to 5.11 or before.

        After two years of work to reverse engineer Apple Silicon GPU instruction set and to implement the kernel driver, Asahi Linux has finally got an alpha-quality release of its GPU driver that is already good enough to run a smooth desktop experience and some games, Asahi developers Alyssa Rosenzweig and Asahi Lina say.

        [...]

        Being still an alpha release, there is still much work to do before the GPU driver becomes complete and stable. In particular, OpenGL 3 is still in early stage and Vulkan support is only nascent, although it can reuse the driver, the compiler, and some source code shared with the OpenGL driver. Additionally, the current OpenGL implementation has not passed yet the OpenGL (ES) conformance tests.

      • OMG UbuntuOpen Source Video Editing Levels Up with OpenShot 3.0 - OMG! Ubuntu!

        A new version of OpenShot, a free, open-source video editor for Linux, is available to download.

        OpenShot 3.0 contains over 1,000 improvements and fixes, includes better stability and memory usage, and debuts interesting new performance and export capabilities. This is the first update to the non-linear video editor since last year.

        Jonathan Thomas, the creator of OpenShot, details the changes in a blog post, explain that he and the OpenShot team “worked tirelessly over the past 12 months to identify and fix as many stability issues as possible”. Those less familiar with the app may be unaware it has the nickname “OpenShut” due to recurrent performance issues.

        There’s also improved real-time video playback, said to be ‘smoother’ with ‘fewer freezes and pauses’ during preview thanks to changes made to the editor’s video decoding engine.

      • NeowinOpenShot Video Editor 3.0

        OpenShot Video Editor is a free, open-source video editor licensed under the GPL version 3.0. OpenShot can take your videos, photos, and music files and help you create the film you have always dreamed of. Easily add sub-titles, transitions, and effects, and then export your film to DVD, YouTube, Vimeo, Xbox 360, and many other common formats. What really sets OpenShot apart from other video editors is the easy-to-use user interface.

        OpenShot has many great features, such as trimming and arranging videos, adjusting audio levels, transitions between videos, compositing multiple layers of video, chroma-key / green screen effect, and support of most formats and codecs.

      • Beta NewsOpen Source video editor OpenShot 3.0 now available for Windows, Mac, and Linux

        One of the big reasons some people don't switch to Linux is a lack of video editors. While it's true there are more video editing programs on macOS and Windows, there are some great options on Linux too, such as Kdenlive and DaVinci Resolve.

        Another popular video editing application that runs on Linux is the open source OpenShot. This cross-platform video editor can run on Windows and macOS too, meaning you can try it on one of those platforms to see if it meets your needs before switching to Linux. And now, OpenShot has reached a new major milestone -- version 3.0. The developers brag that it includes over a thousand changes.

        "We have worked tirelessly over the past 12 months to identify and fix as many stability issues as possible in OpenShot. This was a unique challenge, both in finding clever ways to identify and reproduce crashes, and finding solutions that don't impact the performance of OpenShot. A few notable improvements are related to thread safety (during timeline changes and video playback caching), multi-threaded unit tests designed to flush out race conditions and concurrency issues, safer object clean-up and deletion, and updates to the Undo/Redo system to prevent crashes (for example, when spamming undo)," explains Jonathan Thomas, OpenShot Creator.

      • Vincent BernatAkvorado: a flow collector, enricher, and visualizer

        Earlier this year, we released Akvorado, a flow collector, enricher, and visualizer. It receives network flows from your routers using either NetFlow v9, IPFIX, or sFlow. Several pieces of information are added, like GeoIP and interface names. The flows are exported to Apache Kafka, a distributed queue, then stored inside ClickHouse, a column-oriented database. A web frontend is provided to run queries. A live version is available for you to play.

        [...]

        The proposed deployment solution relies on Docker Compose to set up Akvorado, Zookeeper, Kafka, and ClickHouse. I hope it should be enough for anyone to get started quickly. Akvorado is performant enough to handle 100 000 flows per second with 64 GB of RAM and 24 vCPU. With 2 TB of disk, you should expect to keep data for a few years.

        Postfix SASL Authentication is one of the most popular methods for remote SMTP authentication. It’s a secure, reliable, and highly configurable way of sending and receiving emails. Essentially, the Postfix SASL Authentication consists of an authentication server and a client. The client is a mail program that sends the message, and the authentication server validates the credentials of the user. Once authentication is successful, the message is sent and authenticated at the receiving server.

        The following step will configure the Postfix server to relay emails from a remote SMTP server with authentication.

It’s the successor of the highly successful, but R specific, R Markdown ecosystem, bringing all the benefits of R Markdown to other programming langues like Python, Julia and Observable.

        Unfortunately, because of the lack of official arm64 binary sources for some of its dependencies (e.g. Deno, SASS, Pandoc), and as explained to me, their limited bandwidth to support not sufficiently popular architectures like Linux arm64. Quarto does not officially support the arm64 architecture, but that doesn’t mean we can’t make it work on it ourselves.

      A month ago, when the Great Discontinuity happened, I started working on a Steampipe plugin to enable SQL queries against the Mastodon API, along with a companion Steampipe “mod” (suite of dashboards) to display and chart the results of those queries.

      I expect these dashboards will soon be available in Steampipe Cloud, where it will take just a few seconds to pop in your Mastodon access token (from, e.g., https://mastodon.social/settings/applications/new) and begin using the dashboards.

      Meanwhile, if you’re so inclined, you can find the plugin here and the dashboards here. If you’re reasonably technical you can pretty quickly and easily install Steampipe, clone these repos, build the plugin, and start using the dashboards.

      Why would you want to? My own motivation, originally, was to do Mastodon analytics. I thought Steampipe’s SQLification of the API would be a handy way to discern and monitor activity trends during a period of extraordinary flux. And that’s proven to be true, to a limited extent. Here’s a snapshot of the dashboard that uses the instance activity API.

        Java is no longer among the top three most popular programming languages in the TIOBE Index, one of several not particularly definitive yardsticks by which such things are measured.

        According to Paul Jansen, CEO of Netherlands-based TIOBE Software, the rising popularity of C++ has pushed Java down a notch. The index's rankings are now: Python in first place, C second, C++ third, and Java fourth. C++ stepped up to third, and Java fell to fourth.

        "C++ surpassed Java for the first time in the history of the TIOBE Index, which means that Java is at position 4 now," said Jansen in the December update for the TIOBE Index. "This is the first time that Java is not part of the top 3 since the beginning of the TIOBE Index in 2001."

      • Get Your Data On: The Periodogram or Something Else?

        So, which spectral estimator should you pick? The flow chart below presents a reasonable way to pick between spectral estimators. The first question you should ask is, do you want to assume a model for the data? If you don’t know anything about the data or don’t trust what you know, then move to the left side of the flow chart. If the Fourier methods have enough resolution, use the periodogram or the Blackman-Tukey spectral estimator (BTSE). If they don’t, you could try the minimum variance spectral estimator (MVSE). If the MVSE does not have enough resolution, try a high order autoregressive (AR) estimate. The AR method does assume a model for the data, but a high enough AR model can estimate any PSD.

        Sometimes when you see an elegant algorithm, you think "looks great, I just need it to also do X". Perhaps you are able to build X directly out of what the algorithm gives you; fantastic. Or, perhaps you can alter the algorithm a bit, and it works just as well while also doing X. Sometimes, though, you alter the algorithm and things go pear-shaped.

        Tonight's little note builds on yesterday's semi-space collector article and discusses an worse alternative to the Cheney scanning algorithm.

        To recall, we had this visit_field function that takes a edge in the object graph, as the address of a field in memory containing a struct gc_obj*. If the edge points to an object that was already copied, visit_field updates it to the forwarded address. Otherwise it copies the object, thus computing the new address, and then updates the field.

          Since the elves started using Red (https://raku-advent.blog/2019/12/21/searching-for-a-red-gift/) they thought it was missing a better way of testing code that uses it. They tested it using several SQL files that would be used before each test to populate the database with test data. That works ok, but that’s too hard to understand what’s expected from the test not looking at those SQL files. It also added a big chunk of boilerplate at the beginning of each test file for runnig the SQL. In every file it’s the same code, changing only what file to use. So they decided to look for some better way of doing that.

          Searching for it they found a new module called RedFactory. It’s specific for Red and uses factories to make it easier to write and read tests written for code that uses Red. The idea about factories is to have a easy way of adding data to your test DB with default values making that easy to populate the test DB at the same file as the test and setting speccific values only for what is needed on the test.

      This year, the diamond that I discovered was a leather craftsman by the name of Ed Mason. The son of a saddle maker, Ed has continued his father's legacy, crafting some truly cool leather goods for the cowboy and cowboy-adjacent; saddle bags, gun cases, and other western tack make up most of his stock. What really caught my eye, though, was his selection of minimalist bifold card wallets.

      Now, I'm a sucker for a good leather wallet, and while the ones on display were pretty simple in design, it was the sales pitch that really sold me. As I was looking through his stock, Ed took the time to show me how he selected his leather specifically for its character. He appreciated how the scars, scrapes, wrinkles, and other defects from the processing of the leather to the condition of the actual animal added beauty to each piece, rather than removed it, and was eager to share that philosophy.

    • MongabayBlue jeans: An iconic fashion item that’s costing the planet dearly

      Eternally current and always fashionable, blue jeans are among the most-worn articles of clothing on Earth, transcending time, trends, and social class. Their popularity is ubiquitous, so much so that legendary designer Yves Saint Laurent once declared: “I wish I had invented blue jeans. The most spectacular, practical, relaxed and nonchalant. They have expression, modesty, sex appeal, simplicity — everything I hope for in my clothes.”

      Unfortunately for the planet, the production of this garment takes a huge environmental toll.

      A single pair of cotton jeans consumes between 10,000 and 20,000 liters (2,600-5,300 gallons) of water along its supply chain. Add to that large doses of synthetic pesticides, fertilizers, dyes and other chemicals that pollute soils and waterbodies, impacting wildlife and people, plus major energy expenditures that generate high greenhouse gas emissions.

Funnily enough, I had written about the open-source GPT-3 model (GPT-J) only two days before and made zero connection to the two. But now, as LLMs are becoming more sophisticated, more people are using prompts to query specific knowledge.

    • Matt RickardElo Rating

      In 1978, Arpad Elo, a physics professor, and chess master, introduced the Elo rating system as a way to measure the relative skill levels of chess players. Since then, the system has been adapted and applied to a wide range of competitive activities, from video games and sports to online dating and even voting in political elections. The Elo system is based on a simple idea: each player has a numerical rating that represents their skill level, and this rating is adjusted based on the outcome of their games. For example, if a higher-rated player beats a lower-rated player, their rating will go up, while the loser's rating will go down.

    • Science

      • Publishing a long overdue explainer about a scientific consensus

        You’ll most likely have seen instances where the term “scientific consensus” has been misused or misunderstood. People for example often confuse it with appeals to popular opinion or think it is the result of discussions or determined by a vote or just finding a compromise. Because of this, opinion polls - even if predominated by unqualified individuals - are used to argue that no scientific consensus exists for a particular topic even if it clearly does.

        It’s important to note that a scientific consensus is not proof for a scientific theory but that it’s the result of converging lines of evidence all pointing to the same conclusion. It is therefore not a part of the scientific method but is actually a consequence of it. When people argue against a scientific consensus, they are usually misunderstanding the term or are deliberately abusing the ambiguity of the term consensus. A scientific consensus is not infallible but nonetheless represents the best knowledge available on a given scientific topic at a given time. In addition, it provides the foundation for new knowledge by generating follow-up questions for scientists to explore.

        Researchers at Tohoku University, the University of Messina, and the University of California, Santa Barbara (UCSB) have developed a scaled-up version of a probabilistic computer (p-computer) with stochastic spintronic devices that is suitable for hard computational problems like combinatorial optimization and machine learning.

        Moore's law predicts that computers get faster every two years because of the evolution of semiconductor chips. Whilst this is what has historically happened, the continued evolution is starting to lag. The revolutions in machine learning and artificial intelligence means much higher computational ability is required. Quantum computing is one way of meeting these challenges, but significant hurdles to the practical realization of scalable quantum computers remain.

        Today, humans build robots, but in the future, robots could be programmed to build more of themselves. Researchers at MIT’s Center for Bits and Atoms (CBA) have created robotic subunits called “voxels” that can self-assemble into a rudimentary robot, and then collect more voxels to assemble larger structures or even more robots.

        The researchers, led by CBA Director Neil Gershenfeld, concede that we’re still years away from a true self-replicating robot, but the work with voxels is answering some vital questions that will help us get there. For one, the team has shown that it’s feasible to make the assembler bot and the structural components of whatever you’re building can be made of the same subunits — in this case, voxels.

      • AAASMechanical neural networks: Architected materials that learn behaviors

        Aside from some living tissues, few materials can autonomously learn to exhibit desired behaviors as a consequence of prolonged exposure to unanticipated ambient loading scenarios. Still fewer materials can continue to exhibit previously learned behaviors in the midst of changing conditions (e.g., rising levels of internal damage, varying fixturing scenarios, and fluctuating external loads) while also acquiring new behaviors best suited for the situation at hand. Here, we describe a class of architected materials, called mechanical neural networks (MNNs), that achieve such learning capabilities by tuning the stiffness of their constituent beams similar to how artificial neural networks (ANNs) tune their weights. An example lattice was fabricated to demonstrate its ability to learn multiple mechanical behaviors simultaneously, and a study was conducted to determine the effect of lattice size, packing configuration, algorithm type, behavior number, and linear-versus-nonlinear stiffness tunability on MNN learning as proposed. Thus, this work lays the foundation for artificial-intelligent (AI) materials that can learn behaviors and properties.

        Optical fiber has long since replaced copper wiring in core information networks. But that’s not the case for free-space optical (FSO) communications using optical lasers to transmit data through the air. Despite FSO having the potential to provide orders of magnitude more data capacity compared with that of the traditional radio-frequency communications space missions currently rely on, the technology has been stuck on the launch pad because of atmospheric interference that can absorb and scatter the signals, as well as the strict acquisition and tracking requirements for communicating between ground stations and orbiting satellites.

        But now researchers from the International Centre for Radio Astronomy Research, in Western Australia, have developed a coherent FSO link operating at 1,550 nanometers across a turbulent atmosphere between an optical ground terminal and a retroreflector mounted on an airborne drone. Their findings were published this October in Scientific Reports.

      • New quantum computing feat is a modern twist on a 150-year-old thought experiment | UNSW Newsroom

        A team of quantum engineers at UNSW Sydney has developed a method to reset a quantum computer – that is, to prepare a quantum bit in the ‘0’ state – with very high confidence, as needed for reliable quantum computations. The method is surprisingly simple: it is related to the old concept of ‘Maxwell’s demon’, an omniscient being that can separate a gas into hot and cold by watching the speed of the individual molecules.

        “Here we used a much more modern ‘demon’ – a fast digital voltmeter – to watch the temperature of an electron drawn at random from a warm pool of electrons. In doing so, we made it much colder than the pool it came from, and this corresponds to a high certainty of it being in the ‘0’ computational state,” says Professor Andrea Morello of UNSW, who led the team.

    • Security

      • University of TorontoWhy being able to partially distrust a Certificate Authority is good

        One of the arguments I've heard against supporting partial distrust of Certificate Authorities in places like Linux root certificate stores (which you currently can't really do) is that a bad CA can simply backdate TLS certificates to get around things like 'certificates issued from December 1st 2022 onward won't be trusted'. On the one hand, this is technically true (although these days either such a TLS certificate wouldn't be usable in the majority of web browsers or it would soon be detected through Certificate Transparency logs). On the other hand, there are a collection of reasons to think that it's a good thing that browser can do this sort of thing (and thus that more software should support it).

        The original view of CA trust was that it was binary; either the CA was working perfectly fine and would in the future, or the CA was entirely bad and compromised, and should be distrusted immediately. While there have been some CA incidents like this, such as the DigiNotar compromise, in practice a significant number of the CA problems that have come up over the years have been less clear cut than this, such as the WoSign case (and the WoSign case was exceptionally bad in that WoSign actively issued bad TLS certificates). The recent case of TrustCor is illustrative; as far as was reported to Mozilla (and summarized by them), TrustCor never mis-issued any TLS certificates or committed any other clear violations of CA requirements. They were merely sketchy.

        Next-generation electronic devices could feature enhanced security systems built directly into their circuitry to help fend off malicious attacks. Protective “logic locks” — based on an advanced branch of electronics called spintronics — could be incorporated into the integrated circuits of electronic chips to defend chip security, KAUST researchers have shown.

        “The need for hardware-based security features reflects the globalized nature of modern electronics manufacture,” explains Yehia Massoud from KAUST. Electronics companies usually employ large specialized, external foundries to produce their chips, which minimizes costs but introduces potential vulnerabilities to the supply chain. The circuit design could simply be illegally copied by an untrusted foundry for counterfeit chip production or could be maliciously modified by the incorporation of “hardware Trojans” into the circuitry that detrimentally affects its behavior in some way.

        The robot police dystopia will have to wait. Last week the San Francisco Board of Supervisors voted to authorize the San Francisco Police Department to add lethal robots to its arsenal. The plan wasn't yet "robots with guns" (though some police bomb disposal robots fire shotgun shells already, and some are also used by the military as gun platforms) but to arm the bomb disposal robots with bombs, allowing them to drive up to suspects and detonate. Once the public got wind of this, the protests started, and after an 8–3 vote authorizing the robots last week, now the SF Board of Supervisors has unanimously voted to (at least temporarily) ban lethal robots.

        Shortly after the initial news broke, a "No Killer Robots" campaign started with the involvement of the Electronic Frontier Foundation, the ACLU, and other civil rights groups. Forty-four community groups signed a letter in opposition to the policy, saying, "There is no basis to believe that robots toting explosives might be an exception to police overuse of deadly force. Using robots that are designed to disarm bombs to instead deliver them is a perfect example of this pattern of escalation, and of the militarization of the police force that concerns so many across the city.”

      • 33,000+ DMCA notices sent in an apparent attempt to defend the reputation of an alleged Russian criminal--systematic abuse of the DMCA notice-and-takedown procedure

        In April, 2022, Lumen Research Fellow Shreya Tewari reported discovering more than 30,000 fraudulent copyright infringement notices, dating as far back as June 2019, that appeared to be deliberate attempts to misuse the Digital Millennium Copyright Act’s (DMCA’s) notice-and-takedown procedure. In August, Shreya and I discovered an additional 33,000+ notices, some sent as recently as January 2021, strikingly similar to the initial set. The content at the allegedly infringing URLs in the new set is almost entirely related to Stanislav Kondrashov, a controversial Russian oligarch, and his alleged criminal activity. This steady stream of apparently fraudulent notices on just one “topic” is a powerful indicator that systematic misuse of the DMCA notice-and-takedown (N&TD) process is real and ongoing. However, questions such as, how long and how frequently fraudulent or otherwise problematic notices have been or will continue to be submitted, have yet to be answered.

        Since June 2022, I have been assisting with research within the Lumen Database, searching for possible evidence of misuse of the DMCA process. Because I had the example notices that Ms.Tewari discovered, I had a basic understanding of how fraudulent notices might appear and what search methodology to use. My own searches within Lumen found 33,396 notices sent to Google over the course of almost two years by over 40 different notice senders, targeting more than 500 unique URLs.

        Submitted to Lumen between June 2019 and January 2021, these new notices shed light on the abuse of copyright law as a tool for reputation management. They reveal how notice senders, likely acting on behalf of others, fake copyright claims to remove or censor legitimate journalism linking the notice sender’s clients to accusations of criminal activity, corruption, murder, drug trafficking, and the like. This particular set of notices, all revolving around Stanislov Kondrashov, is most probably one of many others just like it.

        According to various news reports, Stanislav Kondrashov is a Russian businessman with a long history of alleged corruption, hostile corporate takeovers, tax evasion, and contract killings. Most of the articles which were cited as infringing in this notice set include material about Kondrashov’s alleged involvement in: the murder of Denis Voronenkov, laundering through the company Telf AG and VEC, funding of the Wagner mercenary group, and large-scale scams involving the resale of coal and refined oil products, among other details.

        Most of the domain names targeted by the 33,396 notices appear to be online news forums. I individually analyzed a randomly selected representative pilot set of 400 DMCA notices within the larger notice set, originating from five different jurisdictions as marked by the notice sender: the USA, UK, Ukraine, Russia, and the Netherlands. Of the 400 randomly selected notices, all were related to Kondrashov’s criminal activity. Within that pilot group, the domains targeted for takedown include legitimate news sources in Ukraine, Russia, Luxembourg, and Norway, including Antikor News, Rus Republic, Vlasti Info, Fraza, Glavk.net, and The Russian Crimes, along with many more.

        Canadian Heritage Minister Pablo Rodriguez has touted Bill C-18, the Online News Act, as critical for Canada’s media sector, but government’s internal modelling suggests there will be limited benefits for most news outlets. Earlier this fall, the Parliamentary Budget Officer estimated that it would generate $329 million per year, with over 75% of that revenue going to broadcasters such as Bell, Rogers, and the CBC. At the time, I noted that meant that “newspapers will receive less than 25% of the funding or about $81 million to split among hundreds of news outlets.” It turns out that the government believes that vastly overstates the benefit as its own modelling estimates about $150 million in total revenues, less than the 50% of the PBO’s estimate. Assuming a similar apportionment of revenues between broadcasters and newspapers, that would place the benefit at just over $37 million for the entire newspaper sector. In fact, as the government has expanded the eligibility to hundreds of additional outlets, the benefits for each organization shrinks even further.

TL;DR GNUnet is GNU's version of IPFS and libp2p. It has some pros and cons over `libp2p`. Like built-in trafic covering, firewall bypass, etc.. But has (much) lower adoption rate and stablity. In any case, it's a fun project and I see potential in it. The pure C API is a pain point I can help fix - with GNUnet++.
