A farewell to Sabayon Linux

Filed under
Linux

After a hiatus of ten months in the blog posts on the Sabayon Linux Website, a couple of posts on 20 November 2020 announced that the distribution was switching its base distribution from Gentoo Linux to Funtoo Linux (‘Sabayon and Funtoo Linux Merge Projects’), and that the distribution was rebranding (‘Sabayon project is rebranding to MocaccinoOS’) and moving to a completely different package manager named ‘Luet’. A new Website and forum for MocaccinoOS were started, and the Sabayon Linux forums and Wiki are no more.

Although my first experience of Linux was Ubuntu in 2006, it was Sabayon Linux in early 2007 that turned me into a full-time Linux enthusiast and got me interested in the Portage package manager and Gentoo Linux, which I have been using as my main OS for many years now. My interest in Sabayon Linux waned when it moved to a binary package manager (‘Entropy’), and later when it switched from OpenRC to systemd.

CentOS is gone—but RHEL is now free for up to 16 production servers

Filed under
Red Hat

Last month, Red Hat caused a lot of consternation in the enthusiast and small business Linux world when it announced the discontinuation of CentOS Linux.
Long-standing tradition—and ambiguity in Red Hat's posted terms—led users to believe that CentOS 8 would be available until 2029, just like the RHEL 8 it was based on. Red Hat's early termination of CentOS 8 in 2021 cut eight of those 10 years away, leaving thousands of users stranded.

As of February 1, 2021, Red Hat will make RHEL available at no cost for small-production workloads—with "small" defined as 16 systems or fewer. This access to no-cost production RHEL is by way of the newly expanded Red Hat Developer Subscription program, and it comes with no strings—in Red Hat's words, "this isn't a sales program, and no sales representative will follow up."

We are told by our governments that in the current crisis the single most important action we can take is to stay at home and minimise the amount of contact with others. The new variants of Covid-19 are much more transmissible than the virus’s previous version. The advice to stay safe is therefore even more important. It’s only with everyone abiding by the law can we protect our health services and save lives.

In this series, we look at a range of home activities where Linux can play its part, making the most of our time at home, keeping active and engaged. The change of lifestyle enforced by Covid-19 is an opportunity to expand our horizons, and spend more time on activities we have neglected in the past.

HowTos

CrowdSec is an open source cybersecurity detection system meant to identify aggressive behaviors and prevent them from accessing systems. Its user-friendly design offers a low technical barrier of entry with a significant boost to security.

A modern behavior detection system written in Go, CrowdSec combines the philosophy of Fail2ban with Grok patterns and YAML grammar to analyze logs for a modern, decoupled approach for securing the cloud, containers, and virtual machine (VM) infrastructures. Once detected, a threat can be mitigated with bouncers (block, 403, captcha, and so on), and blocked internet protocol addresses (IPs) are shared among all users to improve everyone's security further.

  • Simple-Mail Qt library 2.3 released

  • Block spammers/abusive IPs with Pf-badhost in OpenBSD. A 'must have' security tool!

    But how does it do all this? By periodically pulling IP addresses from well-known and well-respected spammer-IPs databases, where bad IP addresses are frequently logged (dangerous IPs reported by internet users) and stored.

    Then adding all collected IP addresses to the PF firewall (as an IP-table) that is already active on your server (hopefully?), and through that way, prevents their access to your server. So sort of works with the PF firewall.

    The blocklists are pulled from quality, trusted sources. The 'Spamhaus', 'Firehol', 'Emerging Threats' and 'Binary Defense' block lists are used as they are popular, regularly updated lists of the internet's most egregious offenders.

  • Chris H-C: Doubling the Speed of Windows Firefox Builds using sccache-dist

    I’m one of the many users but few developers of Firefox on Windows. One of the biggest obstacles stopping me from doing more development on Windows instead of this beefy Linux desktop I have sitting under my table is how slow builds are.

    Luckily, distributed compilation (and caching) using sccache is here to help. This post is a step-by-step version of the rather-more-scattered docs I found on the github repo and in Firefox’s documentation. Those guides are excellent and have all of the same information (though they forgot to remind me to put the ports on the url config variables), but they have to satisfy many audiences with many platforms and many use cases so I found myself having to switch between all three to get myself set up.

  • How to use C++ Priority_queue? – Linux Hint

    In C++, a queue is a list data structure where the first element to be put in the list is the first element to be removed, when removal is to take place. A priority queue in C++ is similar, but has some ordering; it is the element with the greatest value that is removed first. The priority queue can still be configured so that it is the element with the least value that is removed first. Any queue must have at least the push() function and the pop() function. The push() function adds a new element at the back. For the normal queue, the pop() function removes the first element ever pushed in. For the priority queue, the pop() function removes the element with the highest priority, which could be the biggest or smallest, depending on the ordering scheme.

    BC Security is the team who is currently maintaining the most active fork of Empire. In August 2019, the original maintainers archived the project, but with Open-source projects (as long as they don’t break software licenses) other groups can take someone else’s code and improve upon it. This is exactly what BC Security did, forking the project, to keep the flame of PowerShell Empire alive.

    Creator DuctTapeMechanic loves sports and electronics, so for a recent project he decided to combine his two passions by hacking a speed bag to keep track of his punches.

    As shown in the video below, the first step was to get it physically set up, modding an old metal bed frame into a support structure. He also added a recessed NPN capacitive sensor to pick up when the bag hits the back of the platform.

    The sensor sends “hit” signals to an Arduino Uno via a PC817 optocoupler. The board then counts punches and displays the number of hits on an LCD screen mounted just above eye level.

    EasyOS for the Pi4 might be a bit beta-quality in places, but overall quite a nice experience. The "beta bits" I will of course keep working on -- as there is an "update" icon on the desktop, it will be easy-peasy to update.
    Write the image to a good-quality and fast microSD-card (Class 10) or USB-stick (example: SanDisk Ultra), at least 8GB so that you have plenty of space for anything in the future. Though, a minimum of 2GB will work. As to the host board, even a Pi3B with 1GB RAM will work, or rather "just work" -- I recommend at least a Pi4 with 2GB RAM -- I have the 8GB RAM board.

  • Managing Edge IoT Linux Devices Closely, Remotely, Securely

    With the recent shift from Real-Time Operating Systems (RTOS) to Linux-based embedded systems, there has been a boom in the IoT industry in creativity and expandability and opened doors to a whole new level of automation.

    Unlike the previous generation of IoT devices which followed the “program once, use forever” concept, with the new developments in the IoT industry, mainly the devices based on Linux operating systems that demand more and more flexibility, accessibility, and control. It has been challenging to address all these points at once when it comes to remote monitoring and control of these devices; especially if one produces thousands of those smart devices to be sold worldwide.

    The ability to manage these connected devices (Raspberry Pi, Jetson Nano, or any SOM/SBC that runs a flavor of Linux such as Yocto based, Ubuntu or Debian, etc.) through a single platform, be it just one device, a dozen, or maybe a couple thousand would prove to be immensely productive when considering both the time and cost it’d otherwise take to manage them individually.
