      • Linux CapableHow to Install Monit on Ubuntu 22.04 LTS

        Monit is an open-source utility program that manages and monitors resources and services on Linux systems. Some services and resources managed by Monit are CPU usage, memory usage, server uptime, network connections, and server applications services. It also ensures that all running services are always healthy by restarting services that stop or encounter operating errors. These errors can be caused by many things, such as a power outage or a service crash. Monit can help prevent downtime and keep your system running smoothly by monitoring and managing these resources.

        Additionally, Monit can be configured to send alerts if certain conditions are met, such as high CPU usage or low free memory. This allows you to take action quickly if something goes wrong. Monit is a valuable tool for keeping your Linux system up and running.

        In the following tutorial, you will learn how to install Monit on Ubuntu 22.04 LTS Jammy Jellyfish using the version direct from Ubuntu’s repository and how to configure Monit to be accessible from your browser using the command line terminal.

      • H2S MediaHow to install KDE Plasma Desktop on Fedora Linux - Linux Shout

        Learn the steps to install KDE Plasma 5 Desktop on Fedora 36 workstation desktops and other previous versions such as 35, 34… to get a beautiful alternative to the system’s default GNOME 42 Desktop.

        Fedora plays a not negligible contribution to the Red Hat value chain. It is not meant to generate revenue but instead gives the right direction to the future versions of RHEL. It is an experimental ground for Red Hat. Fedora is allowed to experiment with new technologies, which is why it offers a wide range of packages directly to install using the default system repo. It is more friendly than Redhat and its based distros such as CentOS, Oracle, Rocky, and Almalinux.

        So Fedora can be liked not only by developers but also by desktop users. It brings very new packages and technologies. However, it is not a Cup of tea for those who want a long-term supported Linux. Because you have to perform regular system upgrades as it releases new versions every six months and at the same time three versions are maintained for a short time, whereby the oldest and the latest version only have short-term support.

        • Midichlorians in the blood: Summer Releases

          The first two applications, kmetronome and kmidimon, are now over fifteen years old and are only available for Linux. These two new versions are simply bug fixes, with no new features. But it is interesting to note that in FlatHub they are already based on Qt6 and supporting both Wayland and X11, although the packages in AppImage format still use Qt5. The chances of finding these applications in the official repositories of Linux distributions are slim. In fact, kmidimon was removed from the official Debian repositories with some lame excuse, and it is unlikely to be included again. I can't do anything about it, so please: direct complaints where they belong. Or use the new available distribution formats or the unofficial repositories, like Debian Multimedia, which includes the three mentioned applications and many others.

          The other app, dmidiplayer, is much newer and cross-platform. It is the successor to Kmid2, the KDE karaoke application that I rewrote many years ago. In this new version the most remarkable new feature is the persistent configuration of the songs. This is a feature that was already present in the old Kmid2 and that allows you to store the tempo, general volume, pitch transposition, and MIDI channel settings for each song, which will be applied when it is played again in the future. The other novelty is the individual volume adjustment for each MIDI channel, something that was not possible in Kmid2.

      • The Register UKSystem recovery solution Rescuezilla 2.4 released ● The Register

        Version 2.4 of Rescuezilla - which describes itself as the "Swiss Army Knife of System Recovery," - is here and based on Ubuntu 22.04.

        Rescuezilla is a fork and continuation of the Redo Backup and Recovery project. "Redo" went quiet after 2012, with no new releases until 2020. So, in 2019, the developers behind Rescuezilla forked Redo, updated it, and continued development.

        Since then, the older project has come back to life. A hostile third party had bought its domain name, so rather than pay the typo-squatters' ransom, its developers simply renamed the project to Redo Rescue and restarted work under the new name. (The old URL, which we won't link to, now redirects to an advertising site – so you should probably avoid it.) It looks like Rescuezilla is a friendly fork, inasmuch as the maintainers of Redo Rescue actually link to it. (Good on them!)

        RedoRescue is in active development once again: there's a new version 4.0, based on Debian 11, released in October 2021, although the website still describes version 3 from 2020. Even so, Rescuezilla is a little more modern still. It's now based on Ubuntu rather than Debian, and version 2.4 updates this to Ubuntu 22.04.

      • Make Use OfFedora Silverblue vs. Workstation: 6 Major Differences Between the Two Distros

        Fedora Silverblue is a rapidly maturing version of Fedora Linux that may come to replace Fedora Workstation as the default version someday. On the surface, Fedora Silverblue looks the same as Fedora Workstation; both provide the GNOME desktop and a similar set of apps.

        So what sets Fedora Silverblue apart from Fedora Workstation, and why is it generating such excitement among a corner of the Linux community? The differences are primarily under the hood, and they are a drastic rethink of how to build a Linux distribution.

      • The Register UKA fix for legacy issues around Red Hat crypto ● The Register

        If you're running a mixture of new and old RHEL versions, you may have problems SSHing from new to old. Luckily, someone has worked out a handy way around it.

        The issue is relatively simple: the default security settings in RHEL 9 mean that you can't open an SSH connection to a machine running RHEL 6 or older, which use the deprecated SHA-1 encryption algorithm. There are other, related issues as well: the inability to upgrade old RPM packages that are signed with SHA-1 signatures, or for Firefox to connect to an HTTPS server that uses a very old version of the protocol.

      • IT WireiTWire - Debian project gains control of domain

        The global IP authority has granted ownership of the "" domain name to the Debian GNU/Linux Project and decided that it should be transferred to the community Linux distribution.

        A statement from the project, which lodged a complaint about the domain name, said the decision had been taken by the World Intellectual Property Organisation under its Domain-Name Dispute-Resolution Policy.

        The panel that made the decision said it had found that "the disputed domain name is identical to a trademark in which the Complainant has rights."

        The project, an association of free software developers who produce the Debian distribution, said it was committed to the proper use of its trademarks and would take action when there was any violation of its policy.

      • Tom's HardwareRaspberry Pi Unlocks Door Automatically with Facial Recognition | Tom's Hardware

        Automating your smart home with a Raspberry Pi is a popular idea in the Raspberry Pi community and there are plenty of unique ways to implement the SBC into various designs. Today we’re sharing another home automation-based project created by maker and developer Dillon McCardell who’s using a Pi to operate a door locking system using facial recognition known as AuraLock.

        The system works just as you would expect—it uses a camera to capture images of potential faces. If a recognized and approved face is detected, the Pi will trigger the deadbolt to unlock. Once the deadbolt has been unlocked, users can enter the room and either manually lock the door or do so using the corresponding mobile application.

      • Tom's HardwareRaspberry Pi Home Assistant Runs on Old Sony TV-511 | Tom's Hardware

        If there’s one thing a Raspberry Pi is good for, it’s enhancing hardware with more features than you can shake a stick at. This project, created by Telefrag Entertainment, does just that. It’s using a Raspberry Pi to power his custom home assistant system (opens in new tab) using Jarvis—a Python-based voice assistant application that integrates artificial intelligence to interpret commands.

        This home assistant project stands out as it uses an old Sony TV-511 television for video output. This old TV is both small and big at the same time. Having been released in the 1970s, the Sony TV-511 is not a large TV, but it’s much thicker than TVs you’ll find today. According to Telefrag Entertainment, he picked it up on eBay before turning it into this home assistant display.

A plan is currently in place to begin dropping trigger-based support upon the EOL for PostgreSQL 10 on November 10, 2022. Feedback is requested for use-cases that could potentially change these plans and continue supporting trigger-based partitioning until native partitioning better supports them.

    • IT WireiTWire - Global EV sales rise to 4.2m in 1H22, China tops take-up

      Global sales of electric vehicles totalled 4.2 million in the first half of 2022, a 63% increase year-on-year, the technology analyst firm Canalys says, adding that this included battery electric vehicles and plug-in hybrid electric vehicles.

      The firm found that while many new EVs had been launched during the first six months of the year, supply lagged and long wait times for delivery were common.

      China was the leader in take-up during the period in question, with 2.4 million EVs delivered, equating to 26% of the total passenger cars and a rise from 10% year-on-year.

      The delivery figures were much smaller for Europe (1.1 million – 20% of all passenger cars) and the US (414,000 – 6% of passenger cars).

        It is an easy-to-use, efficient, flexible, and scalable deep-learning platform, originally developed by Baidu, the Chinese AI giant, to apply deep learning to many of its own products. Today, it is being used by more than 4.77 million developers and 180,000 enterprises globally. While comparable numbers are hard to come by for other frameworks, suffice to say, that’s big.

        • Michael West MediaBeetaloo, Scarborough, Labor lockstep with Coalition on high emission gas projects - Michael West

          Will the change of government reset the dial on Australia’s planet-endangering projects? Beetaloo gas fracking, Barnaby Joyce’s petrochemical plant, Scarborough. Australians may soon get the sinking feeling that little has changed from the Morrison-Joyce fossil-fuel spree, writes Callum Foote.

          Australians heard a lot about the climate crisis during the election campaign. And last Wednesday the Albanese government won sufficient cross-bench support to get its 2030 emissions reduction ”floor not a ceiling” target of 43% through the Senate. But when it comes to big polluting projects, it seems that not a lot has changed.

          Consider the evidence. The Albanese government is continuing the Coalition government’s legacy when it comes to gas, a recommitment to Barnaby Joyce’s $1.5 billion port of Darwin petrochemical precinct, continuing the fracking of the Beetaloo Basin in the Northern Territory and refusing to impose windfall profit taxes

      • IT WireiTWire - Australian media reaction to Chinese envoy's speech baffling

        The reaction of the Australian media to an address by the Chinese envoy at the National Press Club in Canberra on Wednesday is quite baffling, given that most of what he spoke about has been known for the last 50 years.

        Xiao Qian's statements have been interpreted as rude, chilling, scary etc but the essence of what he said — China's stance on Taiwan — has been codified in print since the US changed its stand on relations with the mainland and switched from recognition of Taiwan in 1972.

        The understanding at that time was that Taiwan was a province of China and that the US would have a one-China policy that did not afford diplomatic recognition to Taiwan. About 180-odd countries have the same stance on Taiwan and hence the almighty uproar about Xiao's remarks are extremely difficult to comprehend.

      • AccessNow#KeepItOn in Somaliland: authorities cannot quash public protest and access to information - Access Now

        Access Now and the #KeepItOn coalition condemn the ongoing internet blackout imposed by authorities in Somalia’s self-declared Republic of Somaliland, in a knee-jerk reaction to protests against the postponement of the presidential election.

        “Shutting down the internet in times of political instability and unrest fuels crisis and conceals human rights violations against people,” said Felicia Anthonio, #KeepItOn Campaign Manager at Access Now. “Whenever the internet is shut down during high tension moments, lives are endangered. This flagrant abuse of power in Somaliland cannot be condoned in any way.”

      • AccessNow#KeepItOn in Sierra Leone: the government must stop wielding internet shutdowns for political control - Access Now

        Sierra Leone authorities must ensure an open and accessible internet at all times, and especially during political instability.

        On Wednesday, August 10, an anti-government protest erupted in Freetown, Sierra Leone, responding to the rising cost of living. The protest escalated quickly into violence with reports of an unspecified number of deaths including police. During the protest, a nationwide internet shutdown was documented for nearly two hours from 12:00 to 14:00 local time.

        “This outrageous trend of governments flipping the kill switch in times of protests is increasingly alarming and cannot be allowed to become the new norm,” said Felicia Anthonio, #KeepItOn Campaign Manager at Access Now. “Authorities in Sierra Leone must be held accountable for shutting down the internet in order to quell the ongoing protests in the country rather than trying to pass it off as suspiciously-timed ‘maintenance’ activities.”

      • Don't use DuckDuckGo

        Previously, the title was "On DuckDuckGo" which was less inflammatory. However, as I continued to do research for this article, my opinion on DDG continued to worsen.

        For the most part, DDG is the de facto "mainstream" search engine recommended by privacy advocates. It's the default search engine in Tor browser, continues to be recommended by PrivacyGuides and despite their missteps (privacy failures with their mobile browser and Microsoft trackers), it continues to resist criticism in the PrivacyGuides community. The search results are "good enough" for most usecases.

        So what motivated me to write this article? I noticed a peculiar thing where I was getting geographically relevant search results for unrelated search terms (see image below). For example, a search term containing "map project" for a video game would give me search results for my local city/state website that had the word "project" in it.

      • Using Borgmatic with Snapper

        Previously I talked about going full BTRFS. Fedora has incrementally following in openSUSE's footsteps and has not only adopted BTRFS but plans on integrating snapshots as well. However the proposal never went anywhere. So far you can install python3-dnf-plugin-snapper and snapper today. The former takes snapshots prior to and after installing packages. However, due to Fedora's default filesystem layout, some changes need to be made.
