      • AMD Hits Intel Below The Belt In The Datacenter Wallet

        What Intel calls “cloud digestion” as the cause of the massive pullback in spending in its Data Center Group is looking more and more like a case of “Epyc indigestion” for Intel, not for the hyperscalers and cloud builders. And the top brass at Intel should be thanking the heavens for their good luck that capacity for advanced fab processes has been severely constrained at the same time Intel struggled to get its server chip act together. If that had not been the case, AMD might be truly cleaning Intel’s CPU clocks.

        In the first quarter ended in March, AMD was hitting on all cylinders, with its client, server, and game console businesses all up significantly year-on-year as well as up sequentially, delivering a stunning 92.9 percent revenue growth, to $3.45 billion, and an amazing 3.4X increase in net income, to $555 million. All of this good business helped AMD increase its cash hoard by 2.3X to $3.12 billion, which helps cushion the blow on that pending $35 billion acquisition of FPGA maker Xilinx. When you start using “X” instead of “percent” on numbers moving up and to the right, that is always a good sign.

      • Kubernetes configuration patterns, Part 1: Patterns for Kubernetes primitives

        This article is the first in a two-part article series on Kubernetes configuration patterns, which represent ways of configuring Kubernetes applications and controllers. Part 1 introduces simple approaches that use only Kubernetes primitives. These patterns are applicable to any application running on Kubernetes. Part 2 will introduce more advanced patterns. These patterns require you to code against the Kubernetes API when you are developing Kubernetes controllers.

        [...]

        For simplicity, I’ve used only Deployments in the example YAML files. However, the examples should work with other PodSpecables (anything that describes a PodSpec) such as DaemonSets and ReplicaSets. I also omitted fields like image, imagePullPolicy, and others in the example Deployment YAML.

      • FLOSS Weekly 627: Beyond the Browser – Intention Byway

        Browsers and the Web are just one model for making the Internet work. Another is one Doc Searls and his colleagues at Customer Commons are working on: the Intention Byway. With co-hosts Katherine Druckman and Shawn Powers, Doc discusses how it all works: with compute nodes called “intentrons” at the ends and a “byway” for pub-sub messaging in the middle. As a new model, it creates a boundless variety of ways for demand and supply to signal each other in the open marketplace, outside the silos and platforms of the big tech giants. And, of course, it’s all open source.

      • Linux 5.13 Graphics Drivers Are Exciting From Intel Alder Lake S Bring-Up To AMD FreeSync HDMI – Phoronix

        The Direct Rendering Manager (DRM) kernel graphics driver changes have been submitted and merged for the ongoing Linux 5.13 kernel merge window and it brings with it many changes, especially for these open-source Intel and AMD Radeon drivers.

      • Rust heads into the kernel?

        In a lengthy message to the linux-kernel mailing list, Miguel Ojeda “introduced” the Rust for Linux project. It was likely not the first time that most kernel developers had heard of the effort; there was an extensive discussion of the project at the 2020 Linux Plumbers Conference, for example. It has also been raised before on the list. Now, the project is looking for feedback from the kernel community about its plans, thus the RFC posting on April 14.

      • Btrfs on zoned block devices

        Zoned block devices have some unfamiliar characteristics that result from compromises made in the name of higher storage density. They are divided into zones, some or all of which do not support random access for write operations. Instead, these “sequential” zones can only be written in order, from the first block to the last. This constraint poses a new challenge for filesystems, which are normally designed with the assumption that storage blocks can be written in any order. It is thus not surprising that zoned-device support in mainstream filesystems in Linux has been slow in coming; that is changing, though, with the addition of support for zoned block devices to Btrfs in Linux 5.12.

        The only way to overwrite data in a zoned drive’s sequential zone is to reset the write pointer to the beginning of the zone, which immediately erases the entire content of that zone. On the other hand, random read access is fully supported. Many zoned devices also provide some “conventional” zones that support random read and write operations. Zoned devices were first seen in the form of shingled magnetic recording (SMR) drives; the kernel has low-level support for these devices. Zoned devices using flash storage also exist; they trade flexibility for reduced hardware complexity. These devices were added to the NVMe standard in the form of the Zoned Namespaces (ZNS) command set, which has been supported in Linux since the 5.9 release.

        Work has been going on for a number of years to support zoned drives in Linux filesystems. Copy-on-write filesystems should be easier to adapt, as they are designed to avoid overwriting data blocks. Among the existing Linux filesystems, F2FS already supports zoned devices, and allows normal operations on such devices (but requires that the drive provide at least one conventional zone). In addition, zonefs, a special filesystem for zoned devices, was included in the 5.6 kernel. Using zonefs requires applications designed for this purpose, as the filesystem does not support the creation of normal files. Some types of applications do fit the model well, however, for example those with log-structured data.

      • Running code within another process’s address space

        One of the key resources that defines a process is its address space — the set of mappings that determines what any specific memory address means within that process. An address space is normally private to the process it belongs to, but there are situations where one process needs to make changes to another process’s memory; an interactive debugger would be one case in point. The ptrace() system call makes such changes possible, but it is slow and not always easy to use, so there has been a longstanding quest for better alternatives. One possibility, process_vm_exec() from Andrei Vagin, was recently posted for review.

        In truth, alternatives to ptrace() already exist for some tasks. The cross-memory attach system calls were merged for 3.2 in 2011 as process_vm_readv() and process_vm_writev(). As their names would suggest, they allow one process to read from and write to another process’s memory. Those system calls satisfy many needs, but fall short when even more invasive access is needed to another process’s address space. Sometimes, it seems, there is no alternative to running code within the target address space.

        Vagin’s patch set gives a couple of examples of where this access would be useful. User-mode kernels, such as User-mode Linux and gVisor, have to be able to intercept system calls made by a sandboxed process and, possibly, run them in the address space of that process. The Checkpoint/Restore in User space project needs to reach deeply within a process to extract all of the information needed to checkpoint it. Both use cases are currently handled with ptrace() but, once again, better and faster alternatives are wanted.

          AMD engineers today published AMDVLK 2021.Q2.2 as their latest open-source public code drop of their official Linux Vulkan driver.

          While this month AMD published a new Radeon Software packaged driver build with Vulkan ray-tracing support for Linux systems, that driver is binary-only. Now as their first AMDVLK update since that milestone, unfortunately, the ray-tracing support hasn’t made it into this open-source driver yet.

      • timg, a text mode image viewer and video player

        timg is developed by Henner Zeller, and in 2017 I wrote a blog post about creating a snap package for timg. A snap package was created and published on the Snap Store. I even registered the name timg although some time later it became much stricter to register a package name if you are not the maintainer. In addition, it was so early days for snap packages that I think you could not setup the license of the software in the package, and it always came up as Proprietary.

        Fast forward from 2017 to a couple of weeks ago, a user posted an issue that the snap package of timg does not have the proper license. I was pinged through that Github issue and decided to update the snapcraft.yaml to whatever is now supported in snap packages. Apparently, you can now set the license in snap packages. Moreover, timg has been updated and can play many more image and video formats. I figured out the latter because timg now has a lot more dependencies than before.

      • My current HTML boilerplate

        Every element I use for the basic structure of a HTML document, with explanations why.

        Usually when I start a new project, I either copy the HTML structure of the last site I built or I head over to HTML5 Boilerplate and copy their boilerplate. Recently I didn’t start a new project, but I had to document the structure we use at work for the sites we build. So, simply copying and pasting wasn’t an option, I had to understand the choices that have been made. Since I spent quite some time researching and putting the structure together, I decided to share it with you.

      • [Old] Highlighting columns in HTML table

        The other day I looked up colgroup on MDN because something didn’t work the way I expected it to work. I found the solution to my problem, but the demo at the beginning of the page also caught my attention. The author adds a class to the col element, which does nothing with the col element itself, at least not visually, because the element doesn’t get rendered on the page, but it applies the styles from the class to all the cells in the column.

        Why is this interesting? Well, there are no columns in HTML tables, only rows and cells and the col element allows us to style columns anyway.

      • Struggling With the Linux Secure Copy Command? Use This scp Example

        The scp command lets you copy a file efficiently between two different hosts. The syntax for scp reuses the syntax of cp, so it should feel familiar to most Linux users.

        The tricky bit with the scp command is that either source or destination may be remote i.e. a computer connected to another network, different from your local one. When specifying a file for copying, you’ll need to include details about the remote host as well. This includes its IP address and username.

      • Junichi Uekawa: Surrounding a region with Emacs lisp.

        Surrounding a region with Emacs lisp. I wanted to surround a region with HTML tags and here’s what I learnt today. Specifying “r” in interactive gives two numbers, begin and end. When I want to obtain multiple kinds of values in interactive, I can use newlines to delimit. set-marker is an api to keep a marker at relative position even after edits, API needs making make-marker to create an empty marker first, and seems like the number of markers affects editing speed so the API is made to allow reuse of markers. After I got these going I could now write.

        Setting wake-on-lan in Debian way. There’s several ways that your network interfaces can be configured. The Debian way is to use ifup/ifdown. Make sure your network is configured with it by checking ifquery. nmcli d and networkctl list are NM and systemd equivalents of commands. After you know which one is managing your device you can go ahead and set up WoL configuration appropriately. Default Debian installation would probably start with a ifup/ifdown config.

        After I upgraded to Fedora 34, Pipewire refused to detect my audio. I read through forums on Archlinux, etc and mailing list. Initially, I attempted to rectify this issue. However, after spending an hour on this issue, I realised that it is probably because my audio card or whatever hardware is not compatible with it yet.

          A more integrated, unified desktop experience with GNOME 40, which makes key features of the GNOME shell, like search, windows and workspaces more spatially coherent.

        • Looking forward to Fedora 34

          The Fedora project may have managed to shake off its reputation for delayed releases in recent years, but that hasn’t stopped the release date for Fedora 34 from slipping one week to April 27. Modulo a handful of bugs, though, this release is in its final form, so a look at what is coming is warranted. Distribution releases, especially those for fast-moving community distributions, are a good point at which to catch up with the state of many free-software projects and where Linux is headed in general. Fedora 34 includes a lot of changes, including the GNOME 40 release but, for the most part, it looks like an exercise in continuity.
          Incidentally, your editor has been made aware that we are all supposed to call the distribution “Fedora Linux” now, with the bare name “Fedora” reserved for the project. So this article should properly be talking about “Fedora Linux 34″, but old habits die hard.

          Like many distributors, Fedora makes it easy to beta-test its upcoming releases so, on a whim, your editor decided to update his system and see what was coming; what could possibly go wrong? The target Thinkpad, which nicely came with Fedora pre-installed by the manufacturer, was just sitting there waiting for this sort of opportunity. As expected, the upgrade went smoothly and the laptop booted up in the new system without any obvious hitches.

      • Canonical/Ubuntu Family

        • Users warned against upgrading to Ubuntu 21.04

          In a strange turn of events, Ubuntu developers are asking users not to upgrade their Ubuntu 20.10 installations to the recently-released Ubuntu 21.04 due to a strange bug.

          Normally, as soon as a new release is up for grabs, existing Ubuntu users would typically get a notification about its availability and can then switch to the new release with a single click.

          However, a severe issue prompted Ubuntu developers to disable the upgrade prompt. While a manual upgrade was still possible, some top Ubuntu developers want the distro to actively discourage users from upgrading.

        • Ubuntu 21.04 is now available with native Microsoft Active Directory integration and Wayland as the default

          Canonical released Ubuntu 21.04, a new version of the organization’s Linux distribution. The release comes three weeks after the release of beta versions, and can already be downloaded from the official Ubuntu website as desktop, server and cloud versions.

          Updates from Ubuntu 20.10 are not enabled at this point as some systems may end up in an unbootable state if EFI version 1.10 is used. Upgrades will be enabled in the future “once an updated version of shim is available 2hich is compatible with EFI version 1.10″.

          Ubuntu 21.04 is a short-term release, which means that it is good for 9 months of updates before it is running out off support. The latest long-term servicing release is Ubuntu 20.04 LTS.

          The release is powered by Linux 5.11 kernel and GNOME 3.38, and the first that makes Wayland the default on the system, provided that the computer’s hardware supports it.

        • Ubuntu 21.10 is called ‘Impish Indri’ — here is when the Linux distro should be released

          Linux distributions and silly names go together like peanut butter and jelly. For whatever reason, the maintainers of these operating systems seem to enjoy having fun with what they call them — some argue it is childish. Hell, even Google — a multi-billion dollar company — once used sugary dessert names for the Linux-based Android operating system. I am glad the search giant stopped that nonsense.

          One of the most well-known desktop Linux distributions to use funny names is Ubuntu. It famously uses the convention of an adjective and a lesser-known animal, each starting with the same letter. The letter is chosen sequentially by alphabet. For example, Ubuntu 21.04 uses the letter “H” — “Hirsute Hippo”.

          The next version of the operating system, version 21.10, will use the letter “I.” For this release, Canonical has chosen “Impish Indri.” Never heard of a an indri? Neither have I. Apparently it is a type of a large lemur. The word “impish” is a synonym of “mischievous.” The animal looks pretty cool, as you can see from the image at the top of this page.

          Lasers come in two varieties: solid-state and gas tube. As the name suggests, the latter types contain gas. That is a mixture of gas in precise proportions. To fill his DIY laser tube, Cranktown City built an Arduino-controlled gas mixer.

          This device has an Arduino Uno board that drives three relay modules. The first relay switches power to a gas pump, the second relay controls an output valve, and the third relay controls an input valve. A push button starts the pumping process. The pump turns on and the input valve opens. Gas from a storage tank is pumped into an inflatable bag. Once the bag is full, as detected by a limit switch, the two valves flip and the gas pumps into the laser tube.

        • CC Search to join WordPress.org

          The WordPress community has long advocated for a repository with GPL-compatible images, and it’s time to listen to that need. CC Search, a CC0 (Creative Commons Zero) image search engine, is joining the WordPress project with over 500 million openly licensed and public domain images discoverable from over 50 sources, audio and video soon to come.

        • Creative Commons Search to Relaunch on WordPress.org

          The Creative Commons search engine will soon be part of WordPress.org, as Automattic will begin sponsoring several members of the CC Search team to maintain it. The engine currently offers over 500 million images, audio, and videos, under Creative Commons licenses or the public domain, aggregating more than 45 different sources.

          Matt Mullenweg announced the acquisition on his personal blog, saying that CC Search would be “joining the WordPress project.” It is a major benefit to the community, providing a valuable resource for finding GPL-compatible images for use in WordPress-derivative products like themes and plugins. Mullenweg hinted at a long-term plan where deeply integrating CC search into WordPress.org is just the first step…

        • Print Debugging Should Go Away

          There are many reasons why print debugging is still the best option for many developers. rr, Pernosco and similar tools can’t even be used at all in many contexts. However, most of the limitations of these tools (programming languages, operating systems, hardware platforms, overhead) could be mitigated with sufficient investment in engineering work and a modicum of support from platform vendors. It’s important to keep in mind that the level of investment in these tools to date has been incredibly low, basically just a handful of startups and destitute open source projects. If the software industry took debugging seriously — instead of just grumbling about the tools and reverting to print debugging (or, at best, building a polished implementation of the features debuggers have had since the 1980s) — and invested accordingly we could make enormous strides, and not many people would feel the need to resort to print debugging.

            but sometimes it just looks like the Linux command line. As a result books on the “language” have to make a choice of targeting programmers or users. Books that target the programmer tend to assume that the reader knows most of the basics of the Linux command line and proceed from this point to introduce programming features that make scripting possible.This Pocket Primer spends a lot of time discussing the Linux command line and so is much more suitable for the beginner.

            It starts off with a look at what Bash is and what shells use it and what you are likely to encounter in the real world. From here we have a fairly standard account of the command line mostly working with files. My only complaint is that there isn’t enough distinction between the features that are Bash and those that are simply Linux/Unix utilities. Chapter 2 continues with an in-depth look at file commands. Chapter 3 lists “useful” commands – of course what is useful depends on what you are trying to do, but this is not a bad selection.

        Collins was selected by NASA to become an astronaut in 1963. His first flight was a three-day mission aboard Gemini 10, which launched on July 18, 1966. The expedition conducted a docking test and double rendezvous in orbit, and during the flight, Collins became the third person in U.S. history to conduct a spacewalk.

        Apollo 11 was Collins’ second flight into space. In his bestselling 1974 memoir, “Carrying the Fire: An Astronaut’s Journey,” Collins reflected on his solitary time in orbit around the moon — an experience that prompted some to call him “the loneliest man in history.”

                Students and the staff member at the University of Minnesota who were involved in submitting known buggy patches to the Linux kernel project have released a statement which they claim details the full history behind their actions which were geared towards writing a research paper.

                In the statement, which was not attributed to anyone and dated 27 April, they said that the research paper had been withdrawn. It was linked online by the Linux Weekly News website, run by Jonathan Corbet, a developer himself.

                It said the group would detail two aspects: the message log of disclosure of the findings to the community; and the patches submitted.

                “By showing the details of the patches and the exchange of messages, we wish to help the community to confirm that the buggy patches were ‘stopped’ during message exchanges and not merged into the actual Linux code,” the statement claimed.

              • Intentionally buggy commits for fame—and papers

                Fields asked for more details, some of which were filled in by Leon Romanovsky. A paper [PDF] by Qiushi Wu and Kangjie Lu, both of the University of Minnesota, details the process of introducing use-after-free bugs into the kernel for the purposes of, essentially, showing that it can be done—and presenting a paper about it, naturally. Romanovsky continued: “Yesterday, I took a look on 4 accepted patches from Aditya [Pakki] and 3 of them added various severity security ‘holes’.”

                Kernel developers have enough problems with bugs being added by mistake, so patches with intentional bugs are obviously unwelcome. Kroah-Hartman said that all of the patches coming from these developers need to be reverted because “what they are doing is intentional malicious behavior and is not acceptable and totally unethical”. He put together a patch set of 190 reversions that he called the “easy” reverts; there is a set of 68 additional patches that need manual review to determine what to do about them. “Some of them are not able to be reverted as they already have been reverted, or fixed up with follow-on patches as they were determined to be invalid. Proof that these submissions were almost universally wrong.”

                It is a horrifically messy situation, seemingly brought about by researchers who were not too concerned about the effects of their research on others. While Linux developers hardly need the additional work, the resulting “extra” scrutiny of new patches will be beneficial. It is a bit hard to see that as a silver lining, exactly—more like a sad but necessary outcome that was inevitable, as Roeck put it. This incident also should serve as a warning to researchers, at least hopefully, going forward: our communities are not playthings. Our code is free and open, but not for abuse.

            Imagine you are in need of an ISP to host your 100,000 malware distribution sites. Which one would be your first choice? You operate a website for exchanging stolen credit card data, and need a reliable place for web and DNS services. Where do you go? A botnet operation of yours relies on reachable C&C servers, but even the dirtiest ISPs shut them down quickly. What to do?

            Among the western cloud providers that fit the bill are Google, Microsoft and Cloudflare. Choose three.

            [...]

            Firewall rules tend to fail when it comes to malicious activity originating from big cloud providers or other heavily centralised IT players, such as major ESPs (email service providers). While processing Autonomous Systems makes it easier to permit access to one distinct cloud provider, but drop traffic to others located in the same area, they cannot protect against abuse within the AS or IP networks allowed.

            This is precisely why the author is so disappointed about Google, Microsoft and Cloudflare: Blocking them is impossible in almost any circumstances – even dropping traffic to single IP addresses of them already causes huge collateral damage. Worse, they know they can get away with this attitude. Among the motivations behind this post is to raise pressure on such ISPs, striving for a internet being less dirty than the one we have to make do with today.

            Using IPFire’s web proxy in combination with some good and reliable domain-based blocklists2 is not a silver bullet either: While it helps to deny access to knowingly malicious domains hosted on legitimate infrastructure, it is of no use if the offending domain is something like firebasestorage.googleapis[.]com, being abused for hosting phishing sites for years.

Despite reporting more than 10,000 complaints in 2020, the DPC only plans six to seven formal decisions in 2021, meaning that only 0.07% of all GDPR complaints might possibly see a formal decision. This “disappearance” of complaints led Mr Schrems to speculate about a “Bermuda triangle” at the DPC.

This year, images from social media are running a close second to images from Project Greenlight.

              For the second time in several years, Signal has been subpoenaed by U.S. federal investigators for data that the encrypted chat app company doesn’t actually collect.

              In a statement published Wednesday, the company disclosed that it had recently received a summons from the U.S. Attorney’s Office in the Central District of California. The request comes from investigators with the U.S. Department of Homeland Security and asks for data on half a dozen Signal users — including their addresses, “their correspondence, and the name associated with each account,” along with other subscriber data.

              Apparently, the investigators who filed the subpoena aren’t too familiar with the company. All Signal can actually do is provide them with Unix timestamps for when each user account was created and the date when each account last connected to Signal’s servers — because that’s all the company actually collects. As a recent comparison between different data collection practices by various chat apps shows, Signal is in a league of its own when it comes to respecting users’ privacy. Whereas something like WhatsApp, despite offering encryption, still hoovers up a host of analytics and user information including your name, location, contacts, user and device ID, etc., Signal retains pretty much zilch.

Scahill says Joe Biden is the first president in decades to come to the White House after spending significant time in Congress, but it’s not clear whether that will push him toward greater restraint in matters of war and peace. “Biden has spent his entire life railing against executive overreach, demanding that Congress be in charge of declaring war, and he may well be presented with a conflict around the world where it’s going to really call the question on which Joe Biden shows up: Joe Biden, commander in chief, or Joe Biden who spent most of the past 50 years as a senator demanding that Congress be given its proper authority,” says Scahill.

        The audit is being conducted by Florida-based tech company Cyber Ninjas, owned by Doug Logan, a known QAnon conspiracy theorist who, in advance of the recount, speculated that it would garner an extra 200,000 votes for Donald Trump, according to the Huffington Post. Logan himself has widely spread false claims on Twitter that Trump lost the election due to systemic fraud, without of course supplying any evidence.

Cyber Ninjas has so far refused to hand over such information, claiming it would “compromise the security of its recount,” according to The Arizona Republic. The company also alleged that divulging the details of its recount procedures would threaten its trade secrets.

Although Cowen notes this only briefly, others have been more explicit that fewer people, leading to decreased consumption and reduced economic growth, will damage the global economy. This is the case only if humanity stubbornly pursues an 18th-century economic system that understandably did not anticipate the constraints of the 21st-century world.

        • ‘It’s a massive injustice’: inside a film on the dangers of overpopulation

          When asked why people might perceive him as evil, he sheepishly replies: “By wasting a limited resource that should be left for future generations.” It is this dichotomy of consumption and conservation that’s the root of the new documentary 8 Billion Angels.

          It’s a film about the connection between climate change and overpopulation, demonstrated through the intersection between human geography and resource management. It’s the brainchild of producer Terry Spahr, who previously worked in the private sector but the realities of climate change frightened him into action.

        • Population growth and resource depletion

          Students may have a hard time understanding that population growth is controlled not only by birth and death rates but also by the present population. The mathematics of exponential growth govern the prediction of population growth. In some cases, you may want to point out that students may have heard of exponential growth in other contexts, such as compound interest or the spread of viral disease. The rate of population growth at any given time can be written: [...]

        Verizon Media could fetch as much as $5 billion, said the people, who asked to not be identified because the matter isn’t public. The company is talking to Apollo Global Management Inc. about a deal, they said. It couldn’t immediately be learned how a deal would be structured or if other suitors may emerge. No final decision has been made and Verizon could opt to keep the unit.

        In both cases, however, it’s highly unlikely that corrections will ever penetrate the consciousness of the average person who shared straight-faced posts referencing these fake stories on Facebook, Instagram, Twitter, or the other social media sites. On the contrary, you’ll probably be hearing right wing relatives griping about Harris using her book to indoctrinate migrant children and “jokes” about Biden’s burgers for years to come.

        After the European Parliament’s Home Affairs Committee (LIBE) agreed to a new EU regulation to prevent the dissemination of terrorist content online (TERREG) by 52:14 votes last week, the regulation has now been deemed approved by the plenary without a vote. The regulation will allow national authorities to have Internet content removed, even if hosted in another Member State, within one hour, without requiring a court order. The proposal has been criticized by numerous NGOs as well as UN Special Rapporteurs, the European Union Agency for Fundamental Rights (FRA) and the International Commission of Jurists (ICJ).

Scahill says that during his years in the U.S. Senate, Biden “almost never meets a war he doesn’t support,” becoming one of the most hawkish figures in Washington in the 1990s and 2000s. Scahill also discusses Biden’s “war against whistleblowers,” from Daniel Ellsberg to Edward Snowden.

      • New Report Shows Curbs to Media Freedom in Europe

        Leading media organizations and watchdog groups have issued a new report concerning threats to press freedom across Europe. It documents a record number of reported violations including physical attacks, harassment, intimidation and online violence against journalists in 2020 — in some cases intensified by COVID-19 pandemic measures.

        This is the third annual report authored by media groups partnering with the 47-member Council of Europe to promote press protection and safety in a region stretching from Portugal to Russia.

        Among its key findings: eroding legal protections for journalists and government interference are threatening free expression and the media’s role as watchdog against abuse.

        In Burkina Faso, violence has fueled a fast-growing displacement crisis, with more than a million people fleeing their homes since 2019, according to the United Nations’ humanitarian affairs body. Three million people are in need of humanitarian assistance, in a country with a population of 20 million.

      • Two Spanish journalists killed in eastern Burkina Faso

        War reporter David Beriain and cameraman Roberto Fraile were killed when the government convoy they were accompanying was attacked yesterday morning on the road leading to the Pama national park in the east of the country, several Burkinabe security and governmental sources told RSF.

        They were travelling with the convoy with the aim of covering its operations against poachers. This park is located near the tri-border Sahel zone – Mali, Niger and Burkina Faso – where several armed groups are active.

        Two years ago, a group of residents from the rural Glades region of western Palm Beach County took powerful sugar companies to court, alleging that the farmers’ harvesting practices were poisoning poor communities in Florida’s heartland.

        For sugar companies, the most efficient way to cull crops is to burn away the plant’s leafy outer stalk, which sends plumes of smoke and ash into mostly Black and Hispanic neighborhoods on the northern edge of the Everglades. Some residents say the smoke is making them and their children sick. The industry disputes that claim and has sought to dismiss the lawsuit.

      • A fired Amazon worker is trying to unionize four NYC-area facilities

        Amazon workers at four different facilities near Staten Island have begun the process of unionizing with the Amazon Labor Union. The organizing effort is being led by Christian Smalls, a former warehouse worker who was fired in March after organizing a walkout to protest unsafe working conditions during the pandemic, according to Protocol.

        The company has responded by posting anti-union messages on TV screens at JFK8, the fulfillment center where Smalls used to work. “KNOW THE FACTS BEFORE YOU SIGN A UNION CARD,” reads one of the messages obtained by Motherboard. “If someone asks you to provide your personal information or sign a union card, do not release your personal information without knowing all the facts.”

        It would have a dramatic effect on the ability of business and governments to continue functioning, especially when most collaboration is happening online. The risks of information breaches, trade secrets, and employee information being leaked would have long-term, negative implications – the very reason businesses and governments rely on encryption to secure their data.

      • Internet freedom declined in Pakistan in 2020, says report

        Internet freedom in Pakistan declined dramatically in 2020 due to increased blocking of political, social and cultural websites by the government, beefed-up operationalisation of an undeclared policy of connectivity restrictions and increased disinformation and weaponisation of the cybercrime law as a tool.

        This is the crux of the findings of the “Annual Pakistan media legal review 2020” report launched by the Institute for Research, Advocacy and Development (IRADA) to commemorate the World Press Freedom Day on May 3.

      • Australian antitrust watchdog goes after preinstalled iOS apps

        As part of an investigation into app store dominance, namely Apple’s App Store and Google’s Play Store, the Australian Competition and Consumer Commission this week called for the two tech giants to give users more choice when it comes to preinstalled apps.

        [...]

        “There is a need for consumers to have more choice through an ability to change any preinstalled default app on their device that is not a core phone feature,” the report reads. “This would provide consumers with more control to choose the app that best meets their needs, and promote more robust competition in downstream markets for apps.”

        So-called “choice screens” are being investigated as a potential solution. Seen on Android, the feature presents users with the option of downloading alternative search engines and browsers, but could be broadened in Australia to include preinstalled apps.

        In Russia, Apple implements a similar feature to adhere to local law, albeit with government-approved apps. Elsewhere, iOS 14 users are able to change the system default browser, email app and search engine in the Settings app.

        • Meril Life Sciences denied compulsory licenses in heart valve dispute [Ed: These patents can only lead to more deaths, nothing else]

          The dispute between Edwards Lifescience and Meril Life Sciences spans numerous jurisdictions and numerous patents. All patents relate to minimally-invasive heart valve technology. Now, the Federal Patent Court in Germany has denied Meril a compulsory licence.

          Edwards Lifescience owns several patents and utility models for this technology, including EP 3 593 762 B1, EP 3 498 226 B1, EP 2 628 464 B1, EP 3 494 928 B1, EP 3 494 930 B1 and EP 3 590 471 B1. These patents protect minimally-invasive heart valves and accessories. A further patent, EP 3 494 929, relates to a delivery system for transcatheter heart valves.

          US company Edwards Lifescience provides the heart valves in four sizes which can be individually adapted to patients’ physical conditions. However, Meril offers its product in a larger variation of sizes.

The referral concerns the question whether the conduct of oral proceedings in the form of a videoconference is compatible with the right to oral proceedings as enshrined in Article 116(1) EPC if not all of the parties to the proceedings have given their consent to the conduct of oral proceedings in the form of a videoconference.

          Mr Campinos spoke with the committee members about the significant role that innovation and intellectual property can play in a sustainable recovery of the global economy. “It’s the innovation sector that’s going to help us get back to better days”, he said.

          A joint report by the European Patent Office and the International Energy Agency found that found that the average annual growth rate of patents for low carbon emissions technologies has fallen to 3.3 percent since 2017, considerably slower than the average level of 12.5 percent in the period 2000-2013.

        • Clean Energy Innovations Slowed Between 2017-19 [Ed: EPO pretends to be doing studies (propaganda), clearly a misuse of a patent office for objectives unrelated to it]

          The new joint study by the IEA and the European Patent Office (EPO), titled “Patents and the energy transition: global trends in clean energy technology innovation”, finds that patents related to low-carbon energy technologies grew on average by 3.3% a year in the 2017-19 period, highlighting that innovation progress will be essential to accelerate the transition to clean energy,

And it’s hard to believe she had nothing better to do at the time (better than such nostalgia). As we noted last year: “The above tweet of a beach was posted [by Melinda Gates] on the date of the arrest/search of their employee, who was at their residence at the time.” He was arrested around the very same time this tweet was posted. As we wrote last year (based on detailed documents obtained from the police department): “This tweet was posted 2 hours and 40 minutes after the door was breached and incriminating evidence collected.” He was arrested later that morning at the mansion of Bill and Melinda Gates (the police records contain detailed timelines to confirm the chronology). Melinda’s first name was also in the CP 'stash'.
