=> ↺ Linux 6.0 Release Candidate Lands, but Linus Insists Version Is Just a Number

• A release candidate for the Linux kernel 6.0 has arrived, but Linus Torvalds is downplaying the significance of the version change. Despite this, there are some substantial improvements to the kernel.

• [...]

• This version is still only a release candidate. Still, expert users can download and compile the kernel themselves. Most users will wait until their distribution packages the final release. Despite Linux kernel development happening at a breakneck pace, Distributions have their own preference for how new their software is. Because Linux kernel improvements often concern security, there is an interest in keeping it up to date.

• The development team does maintain a number of older “long-term” kernels for applications requiring stability, such as servers.

=> ↺ Raider – Stupid Simple App to Shred Files in Linux Desktop | UbuntuHandbook

• Looking for a file shredder app for Linux? Raider is the one with a stupid simple user interface.

• There are already a few good ways to securely delete files in Ubuntu Linux, such as BleachBit and Nautilus wipe extension. But for a large list of files or those do shred files frequently, this app could be more efficient.

• It’s Raider, also known as File Shredder, a free open-source GTK4 application. With it, you can just drag and drop files into app window, then shred as many files as you want via single mouse click.

• [...]

• It by default overwrites file with random data, which however is a clue that the file has been shredded. User can choose to overwrite with zeros instead to hide shredding.

• And there are options to specify how many times to shred file over, number of bytes to shred, and whether to override the file permissions.

Instructionals/Technical

=> ↺ 10 Useful SSH Commands in Linux | LinuxCloudVPS Blog

• In this blog post, we will show you the ten most used SSH commands in any Linux distribution.

• SSH stands for Secure Socket Shell and is one of the main key services in Linux. The default port that SSH is running on is the TCP/IP port 22, but it can be easily changed due to security reasons. System Administrators are using this system to log in to the server and execute commands via the command line. The SSH as the secure shell is a replacement for insecure login programs such as Telnet, rlogin, rsh and etc.

• In this blog post, we will use the Ubuntu 22.04 OS. You can use any Linux distribution. Let’s get started!

=> ↺ How to Install Bagisto eCommerce on Ubuntu 22.04 – RoseHosting

• In this tutorial, we are going to explain in step-by-step detail how to install the Bagisto eCommerce platform on Ubuntu 22.04

• Bagisto is an eCommerce platform written in PHP with a Laravel framework and uses Vue.js as a frontend Javascript framework. This web application is used as an online store on which you can create and manage thousands of products for your business. In this tutorial, we will install the LAMP stack and configure Bagisto eCommerce to be accessible on the domain.

• Installing Bagisto eCommerce on Ubuntu 22.04 is a straightforward process that can take up to 30 minutes. Let’s get started!

=> ↺ Firefox, language packs & how to remove

• Computer problems are, on both the micro and macro scale, quantum mechanism problems. In other words, unless you take a look, you won’t know whether you have one or not. This happened to me when I, for a reason that currently eludes my conscious memory, decided to check the addons page in Firefox on one of my Linux machines. Casually, I went through the different categories in the sidebar, and then clicked on Languages, and here, lo and behold, I discovered that my Firefox has two extra language packs installed in addition to my default one, English (US).

• These were English (CA) and English (GB) packs. I wasn’t sure why there were there, but I also knew I wanted them removed, because a) there’s no reason to use more than one dialect of English really, even if you might end up trying to spell things in various different ways b) the only acceptable version of English for computer interfaces is American English. Only, I discovered next, they couldn’t be removed. Hence, this tutorial.

=> ↺ How to install iRedMail on AlmaLinux

• In this tutorial, we are going to install iRedMail on AlmaLinux and explain the installation process in step-by-step detail.

In this blog post, we are going to install the iRedMail email server with the installation script. In the installation script are included Nginx as a web server, Postfix as a mail transfer agent, Dovecot as IMAP and POP3 server, SpamAssassin as a spam scanner, ClamAV as a virus scanner, OpenLDAP, iRedAPD and etc.

• Installing iRedMail on AlmaLinux is a straightforward process and may take up to 10 minutes. Let’s get started!

=> ↺ Bind Process to a Network Interface With Namespaces – Linux Nightly

• Network namespaces are a feature baked into the Linux kernel that allows users to virtualize aspects of a system’s networking. This feature comes in handy in many scenarios, one of which is to bind a process to a particular network interface.

• Normally, the IP routing table is used to determine which interface outbound traffic is sent to. However, in cases where two network adapters are connected to the same network, we would need to create a network namespace in order to manually choose which interface certain processes should utilize.

• In this tutorial, we will show you the steps to create a new network namespace in Linux, create a new adapter in that namespace, how to assign IP information to the adapter, and finally how to bind processes to this interface.

=> ↺ What are Flatpak and Snap and why are they so important to Linux? | ZDNet

• For the longest time, Linux received a bad rap for not just being difficult to use, but for not having the software necessary to be productive. I remember, back in the early days of using Linux (I started in ’97), those issues were very much true. Not only was Linux complicated to get up and running, but installing software generally required a nightmare of dependency installations and manually compiling software.

=> ↺ How to Back Up and Restore Your GPG Keys on Linux

• Privacy is an increasingly hot topic. On Linux, the gpg command lets users encrypt files using public-key cryptography, in which case losing your encryption keys would be catastrophic. Here’s how to back them up.

In this article, we will show you how to install Fish Shell on Ubuntu and Linux Mint.

Desktop Environments/WMs

GNOME Desktop/GTK

=> ↺ GNOME 43.beta released

• GNOME 43.beta is now available. It also marks the start of the UI, feature and API freezes (collectively known as The Freeze). String announcement is also in effect now, in advance of the String freeze which starts 27 August. If you’d like to target the GNOME 43 platform, this is the best time to start testing your apps or extensions.

• You can use the 43beta branch of the flatpak runtimes, which is now available on Flathub beta.

• This release moves WebKitGTK to build against libsoup3, which is now the recommended version to use.

• [...]

• This is beta quality software. This release is intended for GNOME developers and beta testers.

=> ↺ GNOME Celebrates 25th Anniversary with Beta Release of Upcoming GNOME 43 Desktop

• As expected, GNOME 43 Beta is packed with lots of goodies, including more improvements to WebExtensions support and a new “Take Screenshot” context menu entry for the Epiphany web browser, the ability for the GNOME Boxes virtual machine manager to fetch recommended operating systems from remote address, WWAN 5G connection support to Control Center’s Cellular page and support for privacy screens in the Display page.

=> ↺ New Alert Sounds – Even a Stopped Clock

• Sounds created for GNOME 43 were generated on a mini-computer called Teensy (currently unavailable due to the global chip shortage), running software called Dirtywave Headless written by Timothy Lamb. The software includes other synthesizer engines, but majority of the sounds were made using the 4 operator FM engine. To further complicate things, my favorite algorithm is No.16 where all of the 4 oscillators are carriers, effectively being equivalent to a 4 oscillator analog synth.

• [...]

• To form a complete circle, and to my genuine surprise, my old friend Noggin from the Jeskola Buzz days has composed a great track using only samples from the gitlab issue (my involvement with music trackers predates GNOME or Free software in general. An old friend indeed).

Distributions and Operating Systems

New Releases

=> ↺ IPFire 2.27 – Core Update 170 is available for testing

• The next Core Update is available for testing. It features new IP blocklists for the firewall engine, significant improvements to Pakfire, modernizes the default cryptographic algorithm selection for IPsec connections, as well as a new kernel, and a plethora of bug fixes and security improvements under the hood.

Slackware Family

=> ↺ liveslak 1.6.0 feature release, plus a new set of ISOs for Slackware Live Edition | Alien Pastures

• Liveslak is my favorite project, it’s fully under my control, I built it from scratch, I get good improvement ideas from its users and Patrick helps when liveslak needs something new from Slackware. There are times that it gets less attention though, and in the first half of 2022 there was not much activity – some minor updates whenever I needed to release a fresh batch of Live ISO images. Most of that inactivity was caused by burnout.

• But then someone mentioned Ventoy to me, because liveslak ISOs would not boot from a Ventoy disk and they hoped I would be able to fix that. At first I was like “I don’t care for it, why should I put effort in supporting it” but on second thought and reading through its web pages, my opinion changed in favor of Ventoy. In fact, it is a quite the unique piece of software and I am using it myself now.

• So what does it do? Ventoy takes a USB stick, formats it and puts a Linux kernel, a Grub bootloader and some smart tools on it. Then you can put as many bootable images (ISOs, IMGs and so on) on its first exfat-formatted partition as there is room. Ventoy will automatically populate the Grub boot selection screen with all bootable images it could find on that partition. You can then boot any ISO straight from that menu.

• [...]

• Ventoy is now fully supported. Liveslak 1.6.0 implements the “Ventoy-compatible” guideline. This means, Ventoy won’t apply any “hooks” to liveslak when it boots its ISO image, and liveslak figures out for itself how to boot. You’ll see the message “SLACKWARELIVE: (UEFI) Ventoy ISO boot detected…” (or ‘BIOS’ instead of ‘UEFI’ if you have an older computer).

Debian Family

=> ↺ Parrot Security OS: How to Install It and What to Expect

• The Parrot OS is a security-focused Linux distribution comparable to Kali OS. It is based on Debian Linux and, like many Linux distributions, is open-source and free to use.

• Parrot is designed to offer privacy, development, and security and is equipped with various digital security and forensics tools and libraries. It also features development tools and privacy protection tools.

• While it comes with the MATE Desktop Environment by default, users can install other DEs if they prefer.

• In this post, we briefly discuss Parrot OS’s features and walk you through how to install it on your computer.

• [...]

• The Home Edition comes with the full office suite, VLC, GIMP, anonymity tools, full disk encryption, and a range of development tools to supplement the supported programming languages and frameworks.

Canonical/Ubuntu Family

=> ↺ The first point-release for Ubuntu 22.04 LTS is now available | GamingOnLinux

• Canonical announced the release of Ubuntu 22.04.1 LTS which brings together an updated download with all the bug fixes, updated apps, driver upgrades and more. Users will now also be prompted to update from earlier versions of Ubuntu, or automatically as part of update scheduling.

• Since this is an LTS release (long term support), it will see updates until April 2027.

• While not a major new distro release, it’s worth noting since this is the first proper big update since the release of Ubuntu 22.04. A long list of the changes can be seen on their official Discourse forum like NVIDIA driver updates, Mesa driver updates for AMD / Intel, various crash-bug fixes for desktop users, Snap upgrades, kernel and firmware updates and much more.

=> ↺ What’s new with Ubuntu 22.04.1? | TechRepublic

• After a slight delay due to an installer issue, the first point release for Ubuntu 22.04 has been officially released. Although point releases are often overlooked by users, because they aren’t major upgrades, this time around you should certainly run the upgrade immediately.

• The biggest reason is that this point release combines all of the security fixes and improvements that have been added since the initial release of Jammy Jellyfish. So, if you haven’t bothered to upgrade Ubuntu 22.04 since you first installed it, which you should have been doing all along, this point upgrade will add everything you’ve missed in one fell swoop.

Open Hardware/Modding

=> ↺ Real Robot One is a high-performance robotic arm that you can build yourself | Arduino Blog

• Robotic arms are versatile machines and are great for learning about principles of robotics or even doing useful work for hobbyists. That work might be picking and placing components on PCBs, packing boxes, or anything else you can imagine. But to perform that work well, the robotic arm needs more hardware than we tend to see in DIY projects. Pavel Surynek wanted a high-performance robotic arm and the result is RR1: Real Robot One, which features closed-loop feedback for accuracy and repeatability.

• In an open-loop robotic system, the controller only outputs positioning commands and doesn’t receive any feedback. Because it has no feedback, the controller doesn’t know if the position is accurate and can’t actively compensate for issues like backlash in the motors. Closed-loop feedback provides real-time, real-world position data to the controller, so it can ensure that results match commands. RR1 receives closed-loop feedback data from encoders on each of the six joints, which are driven by stepper motors through 3D-printed planetary gearboxes.

=> ↺ Android 13 released [LWN.net]

• Version 13 of the Android system has landed in the Android Open Source Project; the list of changes is long.

Racism

=> ↺ Castes are still castes in Silicon Valley | Stop at Zona-M

• Two years ago I wrote here that “as far as today goes, it is interesting (but sadly unsurprising) to read that as progressive and egalitarian as it is, Silicon Valley seems to ruin Dalit lives just like Trantor, or ancient India“.

• [...]

• “[force] Big Tech to confront a millennia-old hierarchy where Indians’ social position has been based on family lineage, from the top Brahmin “priestly” class to the Dalits, shunned as “untouchables” and consigned to menial labor.”

• We’ll see. For the moment, I can’t help to repeat one of the comments I made in 2020: never, ever confuse “digitally competent” with “rational”. Anywhere. Humans will be humans”

=> ↺ Open Source OSINT Tools and Techniques

• Open Source Intelligence (OSINT) is the practice of collecting information from published or publicly available sources for intelligence purposes. The term ‘Open Source’ within OSINT refers to the public nature of the analyzed data; publicly available information includes blogs, forums, social media sites, traditional media (TV, radio, and publications), research papers, government records, and academic journals. The scope of this information is almost infinite, concerning various people, companies, and organizations. Individuals who leverage OSINT can span from IT security professionals and state-sanctioned intelligence operatives with ethical intentions to malicious hackers with unethical intentions.

• You can use Bash scripts to automate all sorts of tasks. Get to grips with the fundamentals and begin your Bash scripting journey.

• Bash scripts come in handy for automating tasks, and you’ll find they’re great for building simple command line applications. The Bash shell interprets Bash scripts, so you won’t need to install any dependencies to write and run them. Bash scripts are also portable since most Unix-based operating systems use the same shell interpreter.

• Knowledge of Bash scripting is a must for every developer, especially if you work with Unix-based systems.

=> ↺ Jonathan Dowland: Temperature monitoring

• I’ve been having some temperature problems in my house, so I wanted to set up some thermometers which I could read from a computer, and look at trends.

• I bought a pack of three cheap Xiaomi IoT thermometers. There’s some official Xiaomi tooling to access them from smartphones and suchlike, but I wanted something more open. The thermometers have some rudimentary security on them to try and ensure you use the official tooling. This is pretty weak, and the open-source Home Assistant (HA) has support for querying them. I wasn’t already running HA and it looked to do more than I needed right now.

• It’s been long enough since I last looked at something like this that the best in class software was things like multi router traffic grapher, and rrdtool, or things that build on top of them like Munin. The world seems to have moved on (rightly or wrongly) with a cornucopia of options like Prometheus, Grafana, Graphite/Carbon, InfluxDB, statsd, etc.

• How did they get from Kubernetes to Linux? It was the next logical move. Via kCTF, researchers could use Google Kubernetes Engine (GKE) instances. If they could hack it successfully, they got a flag, and potentially some cash. But, while all way back in 1995, the Mozilla Foundation was the first organization to offer bug bounties. Now, everyone’s who anyone offers them. Google, which uses Linux in pretty much everything, is expanding its Kubernetes-based Capture-the-Flag (kCTF) project and kCTF Vulnerability Rewards Program (VRP) to pay more attention to hunting down Linux kernel bugs.

• About 100 small-scale fishers demonstrated along Marine Drive at the Paarden Eiland entrance to Cape Town harbour on Monday. They want government to stop approving permits for oceanic oil and gas exploration.

• They held placards that read: “Fisher’s rights are human rights” and “Oil and water do not mix”. Many passing motorists hooted in support of the demonstration. Liziwe McDaid, Green Connection Strategic Leader, said frustrated fishers had asked for help with the demonstration. She said the message to government was to “stop drilling the oceans”.

=> ↺ The REAL purpose of NFTs: beam hikikomoris up in the metaverse | Stop at Zona-M

• NFTs (non-fungible tokens) are files in distributed online databases, that “prove” that someone “owns” some digital file stored somewhere, usually on the Internet. This does not makes the target file any less copiable, of course, but for whatever reason people are going crazy after attaching NFTs to anything digital, and “investing” huge sums to “own” them.

• [...]

• NFTs are a metaverse drill. NFTs are training for living in the fully virtual “metaverse”, in which digital selves would become more important for their owners than their actual bodies, and markets for digital assets owned via NFTs would be as large, or larger, than those for physical ones.
