Posted in News Roundup at 4:39 pm by Dr. Roy Schestowitz

GNU/Linux

=> ↺ Linux Explained on 5 Levels of Difficulty | HackerNoon

• Linux is a family of free and open-source software operating systems built around the Linux kernel.

• Linux is packaged in a form known as a Linux distribution for both desktop and server use.

• Some popular mainstream Linux distributions include Debian, Ubuntu, Mint, Fedora, CentOS, RHEL, and SUSE.

• Distributions often come bundled with a large selection of free and open-source software.

• It is a popular choice for many applications, such as web servers, databases, programming languages, and more.

• The Linux kernel was first released to the public in 1991 by Finnish computer science student Linus Torvalds.

• The kernel is the core of a Linux operating system and provides basic services such as memory management, process management, device drivers, and system call handling.

• The Linux kernel is released under the GNU General Public License (GPL), which means that anyone can modify it and redistribute the source code.

• Linux runs in a variety of hardware, from embedded devices to mainframes.

• It is widely used in servers, as it is very stable and offers a high degree of security.

• Linux is also popular with developers, as it provides a wide variety of programming languages and tools.

• It is also used extensively in scientific computing, as many scientific software packages are available for Linux.

• Linux is a great choice for many people. It is also very secure and stable, making it a good choice for mission-critical applications.

Desktop/Laptop

=> ↺ Linux Fu: The Chrome OS Flex Virtualization | Hackaday

• You’ve probably heard about Google Chromebooks. Like Android, Chrome OS is based on some variant of Linux, but it is targeted at the “cloud first” strategy so Chromebooks typically don’t have a huge amount of storage or compute power. If you have a real Chromebook, you can also use it to run certain other kinds of programs via virtualization. However, Google has recently pushed out Chrome OS Flex which is meant to install on a spare laptop you might happen to have hanging around. Seems attractive to take that only Windows 7 laptop and repurpose it to run Chrome OS, especially if you can run Linux apps on it. Unfortunately, Chrome OS Flex has a very different use case and I would only recommend installing it if you meet the exact use case it addresses.

• The other option, of course, is to just install Linux on that old hardware. There are several distributions that are made for that purpose and, honestly, even most of the major distributions will work fine on older hardware with a little tweaking to turn off some of the more resource-costly features. That assumes you know how to install, tweak, and maintain Linux.

=> ↺ Businesses should dump Windows for Linux • The Register

• I’ve been preaching the gospel of the Linux desktop for more years than some of you have been alive. However, unless you argue that the Linux desktop includes Android smartphones and ChromeOS laptops, there will be no year of the Linux desktop.

• But there should be. For example, as GitLab recently revealed in its onboarding document for employees, staffers can run macOS, and they can run Linux on their desktops. But Windows? Forget about it!

• Why? GitLab explained: “Due to Microsoft Windows’ dominance in desktop operating systems, Windows is the platform most targeted by spyware, viruses, and ransomware.”

=> ↺ Linux Laptop: Best Choices, Reviews, Comparison, and More

• In this guide, we’ll go through the best Linux laptops, review them, compare them, and write more information about Linux laptops in general.

• Before we begin with anything, just a note: this guide will focus on laptops with a Linux distro pre-installed, not laptops that you can install your own distro on, which are most laptops. Most of the companies featured in this article are dedicated to Linux devices only.

• You can customize most of these laptops – you can get a better CPU, more RAM, more storage, and more while ordering your laptop.

Audiocasts/Shows

=> ↺ The Linux Community at SCaLE 19x – Invidious

• The Southern California Linux Expo is an annual conference in Las Angeles California, that brings the community together and celebrates Linux. In this video, SCaLE 19x coverage continues. This time, the focus is on the community! Also, Jay has a chat with Evan from the Linux Professional Institute.

=> ↺ Switching to a Dumb Phone – Invidious

• This is my new phone and I’m sticking with it for a while. No more smartphone… the dumbphone revolution has begun!

Benchmarks

=> ↺ weston 10.0.91

Applications

=> ↺ HBud – simple audio and video player – LinuxLinks

• Linux has a myriad of multimedia playback software available with a truly impressive range of dedicated music players, dedicated video players, as well as tools that do both competently. The field is exceptionally fierce.

• We are always on the look out for new projects. With frameworks that provide a lot of the multimedia grunt functionality, the barriers of entry for newcomers isn’t that steep. That’s one of the many virtues of open source software; there’s a superb base of libraries and frameworks for any budding developer to tap into.

• HBud is billed as a simple music/video/karaoke app. It’s written in Python, uses GTK4 for its GUI framework, and GStreamer for its multimedia backend. HBud is published under an open source license.

• GStreamer is a superb multimedia framework that offers great support for a wide range of container formats and codecs.

=> ↺ IPFS and their gateways

• The InterPlanetary File System (IPFS) is according to the Wikipedia description: “a protocol, hypermedia and file sharing peer-to-peer network for storing and sharing data in a distributed file system.”. It works a little like bittorrent and you typically access content on it using a very long hash in an ipfs:// URL.

• [...]

• This approach has its biggest benefit of course when you can actually use a remote IPFS gateway. I presume most random ordinary users who want to access IPFS does not actually want to download, install and run an IPFS gateway on their machine to use this new power. They might very well appreciate the idea and convenience of accessing a remote IPFS gateway.

=> ↺ IPFS as a first-class citizen in FFmpeg, who’s next?

• FFmpeg (opens new window) is the leading media framework that allows you to watch videos in almost any format. This framework is at the very core of many applications (think, for example, of OBS Studio (opens new window), KODI (opens new window), VLC (opens new window), and even some game engines rely on it). Allowing FFmpeg to handle the IPFS protocol enables IPFS usage in many more applications than previously possible.

• This post will explain how native IPFS support in FFmpeg came to be, how it can be used, how it might affect you and what the future could potentially hold!

=> ↺ How to Record Audio in Ubuntu and other Linux Distributions

• How to record audio in Ubuntu and other Linux distributions?

• If you want to record a voice over through the microphone of your computer, you can use GNOME Sound recorder or Audacity.

• Using GNOME Sound Recorder is easy but it lacks features. Audacity could be overwhelming initially but it has plenty of features for professional level recording. However, I am not going into that detail in this tutorial.

• GNOME Sound Recorder works with the microphone. There is another tool called Audio recorder and you can use it to record streaming music (from Sptify, YouTube, internet radio, Skype and most other sources) apart from microphone input.

=> ↺ How I wish I could organize my thoughts

• I keep a pen & notebook on my desk, which I make liberal use of to jot down my thoughts. It works pretty well: ad-hoc todo lists, notes on problems I’m working on, tables, flowcharts, etc. It has some limitations, though. Sharing anything out of my notebook online is an awful pain in the ass. I can’t draw a straight line to save my life, so tables and flowcharts are a challenge. No edits, either, so lots of crossed-out words and redrawn or rewritten pages. And of course, my handwriting sucks and I can type much more efficiently than I can write. I wish this was a digital medium, but there are not any applications available which can support the note-taking paradigm that I wish I could have. What would that look like?

• [...]

• Other objects would include flowcharts, tables, images, hand-written text and drawings, and so on. These objects can be placed free form on the grid, or embedded in a page, or moved between each mode.

• The user input paradigm should embrace as many modes of input as the user wants to provide. Mouse and keyboard: middle click to pan, scroll to zoom in or out, left click and drag to move objects around, shift+click to select objects, etc. A multi-point trackpad should support pinch to zoom, two finger pan, etc. Touch support is fairly obvious. Drawing tablet support is also important: the user should be able to use one to draw and write free-form. I’d love to be able to make flowcharts by drawing boxes and arrows and having the software recognize them and align them to the grid as first-class vector objects. Some drawing tablets support trackpad and touch-screen-like features as well — so all of those interaction options should just werk.

=> ↺ Our favorite Linux replacements for antiquated open source tools

• Here at Opensource.com, we thought it would be interesting to survey some of our authors to get a feel for what tools they feel are antiquated (but perhaps still useful!) and what they think of the replacement utilities. What follows is a series of responses and a bit of fun, too.

• [...]

• Clearly, both the fun of open source and the strong opinions are still present, as is the variety of tools and the freedom to choose what works best for you. Perhaps these tools and others like them are old—even antiquated—but they may still serve a purpose. Some of these older utilities inspired more modern solutions without losing their own inherent value. Finally, there’s something to be said for user comfort and familiarity. With open source, all those hours spent developing your foo need not be lost just because some vendor decided it was time for a new release.

• We asked our community of contributors what open source tools they are using in place of those that feel outdated or antiquated.

=> ↺ 2 Tools for Linux Terminal Sharing

• At times, you wish you could explain what you are seeing on the screen of your Linux system to someone else. Although you could exchange screenshots, being able to interact would be so much better; thus, the basis for Linux terminal sharing.

• Several tools let you share a screen, including tmate, tmux, screen, teleconsole, tty-share, ttyd, named pipe/FIFO, WebTTY, and byobu, to name a few.

• In this article, I cover what are generally considered the most common tools: screen and tmux.

Instructionals/Technical

=> ↺ How to Upgrade to Linux Mint 21 “Vanessa”

• The latest version of Linux Mint—21 “Vanessa”—has been finally released. Here’s how to upgrade your Linux Mint system to the newest version.

• A major new version of Linux Mint is now available! Based on Ubuntu 22.04 LTS, Linux Mint 21 brings a modest amount of changes and improvements to an already fantastic Linux distribution.

• While you can always do a clean install, what if you want to avoid backing up all your files and re-installing all your applications?

• Thankfully, the Linux Mint team released a handy tool to upgrade from version 20.3 “Una” to version 21 “Vanessa”. Here’s how to use it.

=> ↺ How to install Cassandra on Ubuntu

• Apache Cassandra is a distributed, wide-column store, NoSQL database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. We already have some articles of Cassandra installation on CentOS and Debian; now I will show you how to install Cassandra on the (so far)latest Ubuntu LTS 22.04.

=> ↺ How to Install Drupal on Ubuntu 22.04 – RoseHosting

• In this tutorial, we are going to show you in step-by-step detail how to install Drupal on Ubuntu 22.04 OS.

• Drupal is a free and open-source CMS(Content Management System) written in PHP. Drupal allows us to customize the webpage easily according to our needs. Drupal is used by millions of people and organizations around the globe to build and maintain their websites. In this installation, we will install Drupal and make the website up and running with the LAMP stack.

=> ↺ Setting Up and Running A Container Registry On Linux

• Docker container images are delivered and stored by an application called Docker Registry. Registries consolidate container images and speed up developer build times. Virtualization provides the same runtime environment, but creating an image might require effort. Container orchestration is successful when employing containers. This tutorial teaches how to set up a private Docker registry and configure it for public access.

=> ↺ How to use a DSLR or Mirrorless camera as a webcam for Zoom calls or Live Streaming

• For Live streaming, OBS Studio is so far the gold standard. It’s a free open source versatile live streaming software you can use for most common live streaming applications. OBS is widely supported across different operating systems including Windows, Mac and Linux

=> ↺ MX Linux makes sharing folders with Samba as simple as it gets | TechRepublic

• I frequently share files on my LAN. Back and forth and back and forth — the sharing fun never ends. To that end, it’s a good thing I can manage those shares with the help of Samba. Once a directory has been made available, I can reach it from any operating system within my network.

• With some distributions, setting up a Samba share means installing the software and then manually configuring those shares via the /etc/samba/smb.conf file. There are some distributions that make the process considerably easier.

=> ↺ How to Use Sar (System Activity Reporter) | Linux Journal

• In this article, we’re going to take a look at the System Activity Reporter, also known as the sar command. This command will help us with seeing a historical view of the performance of our server. You’ll see examples of installing it, running it manually, and more. Let’s get started!

=> ↺ 3 ways to Install Discord on Debian 11 Bullseye Linux

• Discord is an app for instant messaging, chats as well as voice and video conferences that can be used on mobile devices such as smartphones or tablets as well as on the computer. This free communication software was originally designed for gamers to talk to while playing online together or for like-minded people can have group chats on a specific topic. In the meantime, the software is much more than that. On Discord, the focus is on the server: Every user can open their own server and invite friends, acquaintances, family, and colleagues to join. Even if you don’t own a Discord server, still using its client can be a very useful medium to perform calls or write to people from your friend’s list or start group calls.

=> ↺ How to Install Google Chrome on macOS – Quick Installation Guide

• Google Chrome is one of the most widely used web browsers today, with over 1 billion users across the world. While it is available for Windows and macOS – as well as Linux – natively, it can also be installed on OS X using third-party utilities. Installing Google Chrome directly from the official website will only get you so far. Instead, to get the most out of it on a Mac, you need to install it directly from its standalone installer file. Installing Google Chrome on your Mac is not very difficult either.

• There are several ways in which you can install Google Chrome on macOS. In this blog post, we will discuss installing Google Chrome on macOS.

=> ↺ GUADEC 2022 – Dylan McCall

• I spent a week at GUADEC 2022 in Guadalajara, Mexico. It was an excellent conference, with some good talks, good people, and a delightful hallway track. I think everyone was excited to see each other in person after so long, and for many attendees, this was closer to home than GUADEC has ever been.

• For this event, I was sponsored by the GNOME Foundation, so many thanks to them as well as my employer the Endless OS Foundation for both encouraging me to submit a talk and for giving me the opportunity to take off and drink tequila for the week.

• For me, the big themes this GUADEC were information resilience, scaling our community, and how these topics fit together.

=> ↺ GSoC 2022: Third Update!

Distributions and Operating Systems

=> ↺ 12 of the Best Linux Distros in 2022

•  Linux is a far cry from the esoteric bundles of code it once was, and the number of polished distros out there, offering variants for Windows, OS X and Ubuntu, is testament to that.

• If you’re new to Linux or are looking for a change, these distributions are easily among the best options in 2022. This list was designed to cover different experience levels and use cases. So whether you’re a system admin, developer, or a desktop user, you’ll find something to interest you.

=> ↺ Makulu Linux Shift makes shifting between desktop layouts easy

•  I’ve been using Linux since 1997, which (for me) is a badge of honor. Then, using Linux was a serious challenge, and the options were limited. A few years into my journey, those limitations were removed, and all of a sudden, I was staring at more choices than I ever imagined possible. If you didn’t like the desktop interface, change it. If you didn’t like the default software, change them. There was practically no limit to what you could change.

• Although that still holds true, most Linux distributions have curtailed such widespread options — at least on the surface. Unlike those distributions of old, where you could select from any number of desktops during installation, now you’re lucky if your distribution of choice includes more than one desktop option. Of course, you could always download a respin of your favorite distribution, such as Kubuntu, Lubuntu, Xubuntu or any -buntu available, but that’s not the same.

Kali

=> ↺ Kali Linux 2022.3 Released » Linux Magazine

• From the creators of the most popular penetration testing distributions on the planet, comes a new release with some new tools and a community, real-time chat option.

• Kali Linux has been one of the most widely-used penetration testing Linux distributions on the market. With a vast number of pre-installed tools available, security experts and pen testers can use the platform to uncover just about any vulnerability or weakness on your network.

• The 2022.3 release, has a few new tricks up its sleeve, including a new VirtualBox image format, weekly images, and build scripts (so you can roll your own); new NetHunter updates; and five new tools, which are BruteShark (a network analysis tool), DefectDojo (an open-source application vulnerability correlation and security orchestration tool), phpsploit (a post-exploitation framework), shellfire (a tool for exploiting LFI/RFI and command injection vulnerabilities), and SprayingToolkit (a tool for testing password spraying attacks).

Fedora / Red Hat/ IBM

=> ↺ Implementing security benchmarks with Red Hat Ansible Automation Platform

• This article is the first in a two-part series. Here we take a step back and look at the evolving IT security risk landscape and how it is impacting organizations, after which we’ll look at a suggested automated compliance architecture. In part two, we will demonstrate what the automated compliance architecture can look like in action when using Red Hat Insights and Red Hat Ansible Automation Platform.

• Anyone who has owned or been in a car has probably seen at least one or more symbols appear on a car’s dashboard. The dashboard indicates when an issue has arisen that requires attention. You’ll often find that when an issue is not addressed, it ends up consuming more of the car owner’s time and energy, and increases their levels of stress. Are those consequences worth the risk of not quickly dealing with warnings and advisories when they appear, before they have the chance to become a problem in the first place?

=> ↺ Understanding Red Hat Linux Price and Pricing

• “Despite being around for two decades and being one of the most popular Linux server distributions, the pricing of Red Hat Enterprise Linux (RHEL), sometimes called Red Hat Linux, is still a common source of confusion, both among its existing users and those who are just thinking about making the switch.”

• [...]

• RHEL uses a much more conservative release cycle than Fedora. New features are typically first made available to Fedora users and don’t make it to RHEL until they are polished. While both RHEL and Fedora can be used for commercial purposes, only RHEL receives commercial support.

• “Developers and Linux enthusiasts flock to Fedora for the latest features and the opportunity to directly collaborate with Red Hat engineering,” explains Red Hat on its website. “Banks, stock exchanges, hospitals, and businesses that run the world’s leading websites choose Red Hat Enterprise Linux for the platform’s performance, stability, and security, which lets them implement mature and well-organized IT infrastructures across the enterprise.”

=> ↺ OKR planning: How to avoid these common pitfalls

• Numerous impactful tech companies’ success leans heavily on a concept almost half a century old. OKRs – objectives and key results – have enabled large organizations to focus their teams and stay ahead of competition and expectations.

• OKRs are still a bit under the radar – a survey of 1,500 Americans found that only 29 percent of adults in the workforce were familiar with OKRs – but for those using them, they’ve been transformative. The real magic of OKRs is how they help improve efficiencies and awareness by creating a playbook for achieving primary company goals.

• But OKRs are a major driver of growth only when they’re properly attuned to your priorities. A playbook is no good if it’s unclear or sets everyone running in the wrong direction. Several common OKR pitfalls are easy to avoid with the right planning.

=> ↺ 7 skills CIOs say are core to their jobs

• We recently asked CIOs how they have worked to develop their soft skills throughout their career – and which ones have been the most beneficial in their role. Here’s what they had to say.

Debian Family

=> ↺ Devuan & Debian Trademark Authorization

• In February 2014, Bdale Garbee used his casting vote in the Debian Technical Committee to endorse the systemd init system for future releases of Debian.

• The Devuan developers began forking the Debian operating system on 3 May 2016 to maintain ongoing support for Init-style init systems. Devuan is not exactly a fork though: the Devuan developers are simply modifying certain packages to ensure that traditional init systems continue to work.

• In 2022, Lennart Poettering, the leader of the systemd development, migrated from employment with Red Hat to Microsoft.

• Personally, I try to make sure my applications work with and without systemd. I don’t wish to make any comment for or against systemd, Poettering or Microsoft in this context. Nonetheless, I suspect that Debian’s original founders would struggle to get their heads around this situation.

• Having recently acquired the Debian trademark, I want to make a very strong statement in support of the work that Devuan developers are doing.

Canonical/Ubuntu Family

=> ↺ Ubuntu 22.04 and 20.04 LTS Users Receive New Kernel Updates, 8 Security Issues Fixed

All these flaws could allow a local attacker to cause a denial of service (system crash) or execute arbitrary code

=> ↺ Migrating from VMware to an open-source private cloud in financial services | Ubuntu

• This is part one of a two part blog series on open source based private cloud for financial services. This blog describes the need for a cost-effective private cloud to execute a successful hybrid cloud strategy. It also shares a comparison between proprietary and open source based private cloud platforms. In the second part, we will elaborate on the key considerations that financial institutions need to think about when planning to migrate to open source based private cloud platforms, along with the operational benefits of Charmed OpenStack for financial institutions.

• To drive business agility, financial institutions are on a journey to fundamentally reshape their IT infrastructure. As their IT estates grow and become more complex, financial institutions are increasingly facing the challenge to optimise their infrastructure spend. Many financial institutions are adopting scalable and agile cloud infrastructure guided by a hybrid multi-cloud strategy.

We will also list some of the more subtle changes which may not be as noticeable at first, but serve to modify the new operating system under the hood.

Devices/Embedded

=> ↺ How To Design A Pi Case For Laser Cutting – In Depth Tutorial – The DIY Life

• The last couple of times I’ve done a project involving a laser-cut Pi case, people have asked me to put together an in-depth tutorial on how to design them. So I’ve prepared this tutorial using an open-sourced software package called Inkscape to do just that.

• Inkscape is a free vector-based graphics editor that is available for Windows, Mac and Linux, so you can even run it on your Raspberry Pi. If you don’t have it installed already, visit their downloads page to download it for your device.

• This tutorial is going to focus mainly on the design of the case, so I’m not going to go into much detail on how to use the basic functions of Inkscape. There are loads of guides and tutorials for this already, so it’ll be good to be somewhat familiar with the package to start.

• Once you’ve got Inkscape installed on your device, grab your Raspberry Pi and a vernier or ruler to take measurements from it and you’re ready to start.

• What do Docker, GitLab, and Red Hat have in common? Aside from various levels of participation in open source, they’ve all been punching bags over the past few years for non-paying users angry that they’ve taken some freebies off the table.

• When Docker had the temerity to introduce limits for free users pulling containers from DockerHub, or requiring a subscription for large business users, lots of people started complaining and/or looking for a free alternative.

=> ↺ Type support: getting started with syslog-ng 4.0 – Blog – syslog-ng Community – syslog-ng Community

• Version 4.0 of syslog-ng is right around the corner. It hasn’tyet been released; however, you can already try some of its features. The largest and most interesting change is type support. Right now, name-value pairs within syslog-ng are represented as text, even if the PatternDB or JSON parsers could see the actual type of the incoming data. This does not change, but starting with 4.0, syslog-ng will keep the type information, and use it correctly on the destination side. This makes your life easier, for example when you store numbers to Elasticsearch or to other type-aware storage.

• From this blog, you can learn how type support makes your life easier and helps you to give it a testdrive on your own hosts.

=> ↺ What Newsletter Authors Can Learn from the Print Newsletter Era

• Some might say that peak newsletter came and went already, but in some ways, it just means the newsletter space is starting to right-size itself again. A recent piece on Vox’s Recode makes the case that newsletters are not the gold mine a lot of people once thought. “The scaled-down, sobered-up reality of newsletters is also sinking into media and tech companies that became newly interested in them over the last couple years,” the site’s Peter Kafka wrote. If that’s the case, well, it wouldn’t be the first time the newsletter emerged and receded into view. This is a cycle that has happened repeatedly over the last 100 years or so, even before newsletters became purely digital endeavors. And with all of that in mind and a new book on my shelf, I’d like to spend today’s Tedium looking back at some pre-digital newsletter efforts, and the parallels they might carry. Maybe it might offer a good refresher for my fellow newsletter authors out there.

• Microsoft is telling staff across the entire business to cast a more watchful eye over expenses in the face of economic uncertainty.

• Some business travel, external training sessions, and company get-togethers are all falling under the gaze of Redmond’s accountants.

• In one recent instance recounted by a loquacious yet unidentified source, as reported by the Wall Street Journal, Microsoft managers personally paid the bill to feed and water staff at a company picnic, something the multibillion-dollar-profit business would have covered itself before.

• Last month during an earnings call to discuss Microsoft’s financials for its Q4 ended 30 June, chief financial officer Amy Hood said: “We will continue to invest in future growth while maintaining intense focus on operational excellence and execution discipline.”

Security

=> ↺ Anatomy of a basic extension | Almost Secure

• I am starting an article series explaining the basics of browser extension security. It’s meant to provide you with some understanding of the field and serve as a reference for my more specific articles. You can browse the extension-security-basics category to see other published articles in this series.

• Before we go for a deeper dive, let’s get a better understanding of what a browser extension actually is. We’ll take a look at a simple example extension and the different contexts in which its code runs.

• [...]

• So our example extension is going to be a Chrome-compatible one. I’ll discuss the files one by one but you can download the entire source code to play around with here. Unpack this ZIP file to some directory.

• All browsers support trying out extensions by loading them from a directory. In Chromium-based browsers you go to chrome://extensions/, enable developer mode and use “Load unpacked” button. In Firefox you go to about:debugging#/runtime/this-firefox and click “Load Temporary Add-on” button.

• This extension uses questionable approaches on purpose. It has several potential security issues, none of these are currently exploitable however. Small changes to the extension functionality will change that however, I’ll introduce these in future articles.

The toolkit aims to help state and local government officials, election officials, and vendors enhance the cybersecurity and cyber resilience of U.S. election infrastructure. The toolkit resources, which come from CISA, JCDC members, and others across the cybersecurity community, focus on assessing risk and protecting election infrastructure assets commonly targeted by phishing, ransomware, and distributed denial-of-service (DDoS) attacks.

=> ↺ Adopting Sigstore Incrementally

• adopt Sigstore may already sign published artifacts. Signers may have existing procedures to securely store and use signing keys. Sigstore can be used to sign artifacts with existing self-managed, long-lived signing keys. Sigstore provides a simple user experience for signing, verification, and generating structured signature metadata for artifacts and container signatures. Sigstore also offers a community-operated, free-to-use transparency log for auditing signature generation.

• Sigstore additionally has the ability to use code signing certificates with short-lived signing keys bound to OpenID Connect identities. This signing approach offers simplicity due to the lack of key management; however, this may be too drastic of a change for enterprises that have existing infrastructure for signing. This blog post outlines strategies to ease adoption of Sigstore while still using existing signing approaches.

=> ↺ The Proposed Privacy Bill Would Treat Your Phone Data Like Your Amazon Account. This is NOT a Good Thing. – Public Knowledge

• New privacy bill strips consumer protections from voice communications. We can fix this without jettisoning the bill.

• On July 20, something really big happened for consumers: The House Energy and Commerce Committee successfully brought forward bipartisan consumer privacy legislation – the American Data Privacy Protection Act (ADPPA). As Public Knowledge said after passage out of the Committee, “This sweeping bill provides individuals with broad privacy protections across all sectors of the economy,” restricting what and how businesses collect, use, and share consumer data and giving individuals the right to access, correct, and delete the data companies have collected about them, placing them in greater control over its collection and use. These are big wins for consumers and we will be working to try to secure passage of this legislation in this Congress.

=> ↺ Biologists Shouldn’t Teach Physics

• Essential, foundational ideas of physics are being presented to children by teachers who know nothing about them themselves. Able children are being undermined by the belief that there is nothing in the compulsory science curriculum that cannot be taught by any science teacher and that physics teachers, bringing only enthusiasm to an inherently dull subject, are therefore not required for physics lessons.

• Having just finished a unit on forces and motion with 16- and 17-year-olds, we started on work and energy. After some introductory discussions and activities, the students were given a task to research and describe how wind turbines worked, in preparation for a study of the work done by the wind. Prompted to describe how the wind makes the generator turn, each student wrote that the wind’s energy did it. When pressed, one offered that the wind’s kinetic energy spun the blades and the blades’ kinetic energy was turned into electricity. How does kinetic energy do that then? Well, the generator turns kinetic into electricity, they said, something to do with magnets.

=> ↺ GNUNet File Sharing Tutorial and an Alternative to IPFS

• With Web3 on the headlines all the day. I want to shift my view onto more traditional technologies. Blockchain is a great. Really, especially for transactions. Once I had to wire some money to an overseas bank. It literally took a week from sending to confirmed receiving. The fees are high too. With XMR or Eitherium. I can send Crypto to the destination in like 15 minutes. With sane fees. But I think that’s where blockchain’s advitange ends that, I don’t think there’s applications that blockchain can do better than traditional client server architectures.

• Back to Web3. A decentralized web is very attractive. We can solve the most annoying part of internet in one go – dead links. As long as enough machines are hosting the content. A decentralized web will always serve up the content even if the original hoster vanished into the ether. IPFS is probably the 1st thing people think of for this. However, there’s a more old-fashioned system doing the same thing. With much less Cryptocurrency and tech fluff. GNUNet[1]
