The 2022 sambaXP conference was held online at the beginning of June. Videos of the talks given at that event have now been posted on YouTube. Topics covered include Samba in containers, certificate auto-enrollment, symlink races, and more.
This is the last year that we will be adhering to our long-standing tradition of extending the deadline by one week. In 2023, we will break from this tradition, so that the refereed-track deadline will be a hard deadline, not subject to extension.
But this is still 2022, and so we are taking this one last opportunity to announce that we are extending the Refereed-Track deadline from the current June 12 to June 19. Again, if you have already submitted a proposal, thank you very much! For the rest of you, there is one additional week in which to get your proposal submitted. We very much look forward to seeing what you all come up with.
Learn the commands to install Joomla CMS on Ubuntu 22.04 LTS Jammy JellyFish Linux to start your own blog or website.
On the Internet, after WordPress, Joomla is another popular open-source content management system to start with. The software is often offered for your own websites.
It is a widely used CMS (Content Management System) that allows you to create and manage web projects. Being an open-source project, it is not only free but also constantly being further developed by the community.
The core functions of Joomla can be extended as required by components, modules, and plugins. Generally suitable for websites whose content changes frequently or is constantly being expanded. These are, for example, blogs, shops, or communities.
Renaming a directory in Linux is easy, and there are plenty of ways to go about it. From renaming a single directory to finding and renaming many, here’s how to do it.
In our daily computer work, we need to know the IP address of our machine from time to time. This tutorial lists three ways you can use to find the IP address of your local network card in Debian 11 with the help of the terminal.
In this tutorial, we will show you how to install Sysdig on Ubuntu 22.04 LTS. For those of you who didn’t know, Sysdig is an open-source, system-level exploration application that capture, save, filter, and examine the real-time events of Linux systems. In a nutshell, it’s a robust performance analysis meth. You can integrate Sysdig with ansible, puppet, and logstash to extend the functionality.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Sysdig monitoring tool on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.
Moodle is a popular, free, and open-source Course Management system based on PHP released under the GNU General Public License.
The Moodle platform is highly customizable and takes a modular approach to features, so it is extensible and adaptable to your needs. It is probably most popular open source learning management platform available today.
In this tutorial, we will show you how to install Moodle on your Debian 11 OS.
Envoy proxy is a free and open-source service proxy designed for cloud-native applications. In this tutorial, we will show you how to install and configure the Envoy proxy on the Debian 11 server.
LEMP is a popular web hosting stack used by developers and web hosting companies to test and host web applications. It comprises 3 components: the Nginx ( pronounced as Engine-X) webserver, MariaDB, and PHP which is a server-side scripting language.
In this walkthrough, you will learn how to install the LEMP stack on AlmaLinux and Rocky Linux 8.4.
I've always used tiling window managers, first i3 then more recently, dwm. In my search for something even lighter, I've come across dvtm, a window manager for the terminal. It acts, in most aspects, like dwm, having the same behavior, but in my case in a TTY. First impressions are that it's much lighter, obviously, and smoother when especially when scrolling. Still getting used to the keybindings, but I definitely vouch for it. The default meta key is ctrl-g, although I'll probably change it to alt as I'm more used to that. It has the default tiling layout of dwm, as well as a few others.
We all know how awesome YaST can be for administering your (open)SUSE system. From managing the software repositories and the installed software to adjusting the systemd services and sockets. From creating LVM logical volumes to configuring Kdump (or fadump). From inspecting the systemd journal to fine-tuning the boot loader. From configuring network interfaces to adjusting the mitigations for CPU vulnerabilities. From setting the firewall configuration to managing your subscriptions to the different SUSE products… and so much more!
But all that comes with a pretty obvious price. You must install YaST and all its dependencies in the system you want to manage. Those dependencies include the Ruby runtime, either ncurses or Qt (depending if you want the text-based or the fully graphical interface) and some other packages or libraries depending on what you want to achieve. For example, you need libzypp to install software or to manage the repositories.
What if you don’t want to pay that price? Well, we have an special offer for you! Now you can use YaST to administer your system without installing YaST or any of its dependencies. Ideal for lovers of minimal systems like the MicroOS variants of SUSE and openSUSE. All you need is a container engine like Docker or Podman… and you are using one anyways if you are using MicroOS, isn’t it?
Speech to text is one of the most common use cases for artificial intelligence. It's used all over to allow easier human interaction. Phone tree automation is a common use case.
This article will walk you through a speech-to-text example using OpenVINO, an open-source toolkit for optimizing and deploying AI inference. This example is a variant of the OpenVINO speech-to-text demo notebook which can be found in OpenVINO's GitHub repository.
A few people contact me directly trying to run things like PyTorch, which requires large amounts of ROCm to get working (most of which Fedora does not have yet). I feel like a SIG, or at least some wiki page would help organize things a bit for those who want to tackle it but are unaware of the resources available. Also is there a better mailing list for this? I'd hate to keep spamming devel with my ROCm related interest :)
In May I was assigned 11 hours of work by Freexian's Debian LTS initiative and carried over 13 hours from April. I worked 8 hours, and will carry over the remaining time to June.
 The new version of Linux Mint's default desktop will feature improved support for multiple monitors and other enhancements.
The developers of Linux Mint have announced a new version of the default Cinnamon desktop environment, version 5.4. The release comes ahead of the pending release of Linux Mint 21, dubbed "Vanessa."
The biggest change in Cinnamon 5.4 is a new version of the Mutter window manager, according to 9To5Linux. The JavaScript engine is also being overhauled.
PostmarketOS is a Linux distribution optimized for smartphones and other devices with ARM-based processors. Initially designed as a project to breathe new life into old phones by giving them an operating system with long term support, the latest version of postmarketOS now officially supports 27 devices including phones, tablets, and single-board computers.
It’s also now easier to update from one version of the Alpine Linux-based operating system to the next.
We are sad to inform our community that Marina Zhurakhinsakaya died on Saturday.
CW: cancer - Marina died on Saturday after winning her struggle with cancer for three years. We would like to elevate Marina's message to encourage people to test themselves for genetic markers for breast cancer. You can donate in Marina's honor to Dana Farber's Metastatic Breast Cancer Research Fund...
We're wrapping up another great week with the following activities from the Apache community...
Mozilla introduced an Add-on to help you translate web pages locally without transmitting the data to the cloud or server.
Fresh versions of three of the bigger open-source application suites just landed for those seeking to break free from proprietary office apps.
LibreOffice is the highest profile of them, and the project recently put out version 7.3.4, the latest release in the Community version of the suite.
The Document Foundation maintains two versions of LibreOffice; the other is the Enterprise branch.
Both versions are free. The difference is that the Community version is the faster-moving development branch. It's comparable to a free Linux distro, or a short-term Ubuntu release: there's no commercial support, but you may be able to get assistance from other users – in other words, the Community.
This is an unofficial guide to GCC’s internals, aimed at new developers, and at plugin authors.
Source: https://github.com/davidmalcolm/gcc-newbies-guide
I’m a relative newcomer to GCC, so I thought it was worth documenting some of the hurdles I ran into when I started working on GCC, to try to make it easier for others to start hacking on GCC. Hence this guide.
For those who would like to know more about how GCC works, David Malcolm has enhanced his GCC for new contributors guide with a section on GCC internals.
Last week I wrote blog post Do you want to get started with Perl v5.36? where I shared my experience with the latest release Perl v5.36.
Lately I’ve been diving deep into tokio’s mini-redis example. The mini-redis example is a great one to look at because it’s a realistic piece of quality async Rust code that is both self-contained and very well documented. Digging into mini-redis, I found that it exemplifies the best and worst of async Rust. On the one hand, the code itself is clean, efficient, and high-level. On the other hand, it relies on a number of subtle async conventions that can easily be done wrong – worse, if you do them wrong, you won’t get a compilation error, and your code will “mostly work”, breaking only in unpredictable timing conditions that are unlikely to occur in unit tests. Just the kind of thing Rust tries to avoid! This isn’t the fault of mini-redis – to my knowledge, there aren’t great alterantive patterns available in async Rust today (I go through some of the alternatives in this post, and their downsides).
[...]
If you’ve not seen it, mini-redis is a really cool bit of example code from the tokio project. It implements a “miniature” version of the redis in-memory data store, focusing on the key-value and pub-sub aspects of redis. Specifically, clients can connect to mini-redis and issue a subset of the redis commands. In this post, I’m going to focus on the “pub-sub” aspect of redis, in which clients can publish messages to a topic which are then broadcast to everyone who has subscribed to that topic. Whenever a client publishes a message, it receives in response the number of other clients that are currently subscribed to that topic.
Following years of supporting humanitarian organisations and its causes, self- taught African fine artist Reggie Khumalo, who uses his art as a vehicle for social change, will this month be visiting World Food Programme (WFP) projects in Tanzania, Burundi, Rwanda, Uganda and Kenya.
This article will explore the key benefits and potential drawbacks of open source security in under a minute.
Drupal has released security updates to address a Guzzle third-party library vulnerability that does not affect Drupal core but may affect some contributed projects or custom code on Drupal sites. Exploitation of this vulnerability could allow a remote attacker to take control of an affected website.
As open-source software becomes increasingly common in the infrastructure of businesses, it is essential to ensure the security of the software being relied upon. An increasingly popular cyber security solution is open-source SAST (Static Application Security Testing) and DAST (Dynamic Analysis Security Testing) security scanning, which give IT technicians and developers the ability to access the code of a certain piece of software to remove threats or improve the strength of its security.
comfortable new start I've ever had on a job. A big part of that is probably the fact that I'm senior now and have finally been able to internalise that. I know my strengths and skills. I know what I can bring to the table.
The tech stack is diverse but not too complicated. We use the tools we need, but none of the extra and horrible cruft that large cloud providers offer. Privacy has by necessity been a part of the product since the very beginning; Schrems II hasn't caused anyone to panic or scramble because no one had assumed that the Safe Harbour provision would stand up to EU human rights in the first place.
Amid the current crypto price drop. I want to write about what cryptocurrency is actually useful for. And what I believe Crypto should be used for. Non of those NFT and ICO bulls*it. Or you can think this as my DD for investing in crypto. Or confirming my confirmation bias if you read WSB.
At the very core of the cryptocurrency is the idea of trust and decentralization. Our current banking system depends a whole lot on trust. Users trust the bank to store, provide access and transfer their money given the user's explicit instruction. And do it very reliably. We all know how that went. Credit card fraud is a real problem. 3D Secure is really the bank, merchant and the user passing the buck. Not to mention the shit show of the bank's website and mobile app security. All of them claim "secure". But they never get close the level of security that most computer scientists and engineers are looking for - Noting can possibly fscks up unless I fsck-ed up.
The amount of money that gets stolen daily over crypto is pretty big too. So I’m not super convinced it does a particularly good job in that regard. Like, “it’s more safe and secure” is not the hot take I would’ve expected on the same day that Celsius Network collapsed stealing everyone’s savings.
Say what you will about crypto, a few things about it make a lot more sense than what we have with our current banking system. Restricting the ability to send money exclusively to the owner of such funds is obvious. Anything else is absurd.
It is surprising that the current system works. Anyone can charge your account, leaving it up to you to argue with the bank. Signatures are no longer required, making it even stupider.

I switched to Minor Figures oatmilk, which also became unavailable immediately. I love their packaging, but Oatley is a little better. But I managed to order Minor Figures directly from the distributor, 4 cases (of 6) at a time. I think the only way to do so was to sign up for autodelivery, every six weeks. I figured I'd do it for a couple of deliveries, and cancel.
More easily said than done. A year later, dozens of emails and phone calls to Minor Figures and my bank, I am drowning in oatmilk. Oatley is now available again, and is a bit cheaper at Whole Foods than what I am charged for Minor Figures (because in the US, the dealer mafia is protected, and you cannot buy cheaper from the factory). But I just can't get my order canceled.
It's been a roller coaster of a week at Rob's Gemini Capsule, and in my own life. Much of it involves a personal matter I won't bore my visitors with, but it has taken up much of my mental energy for the last seven days.
[...]
Two major changes are coming to the chess backend on Rob's capsule: I am using a database instead of flat files to store game data, and I am using a proper chess engine for calculations instead of a crude shell script. I have never seriously worked with databases before, nor have I touched a chess engine or the UCI protocol, but making these changes will allow me to add more features to the frontend. I may not be able to finish by 1 July, but the project has already been quite informative, and I know visitors will have a better chess experience as a result.
A little over a month ago the United Kingdom’s Competition Appeals Tribunal (CAT) heard arguments in Meta’s appeal against the UK Competition and Markets Authority (CMA) order that Meta (Facebook’s mother company) unwind its previously completed acquisition of GIPHY, the provider of a searchable GIF database and related services. The CMA’s order was premised on a rather questionable theory of harm. While ostensibly about innovation and dynamic competition, the CMA’s arguments basically boiled down to “any reduction in the number of players in the market must be blocked, no matter how insignificant nor how beneficial the transaction”.
Such an approach has obviously problematic consequences for innovation, investment, and entrepreneurship. These effects would be felt not only in the UK, which is in a state of regulatory competition with the European Union, but also internationally due to competition law’s extraterritorial reach. The CAT’s judgement will surely touch upon the extent to which the CMA is able to apply the law in this way, but the hearing revealed another important aspect of the case.
Indeed, on the first day of the hearing, it was revealed that the CMA withheld for about 14 months the fact that Snap had purchased Gfycat (a GIPHY rival, as some had pointed out in the administrative process). The CMA also withheld the fact that Snap had been interested in purchasing GIPHY, but only at a much lower valuation. Snap valued GIPHY at $142 million (not the $315 million that Meta agreed to pay) and, as Meta’s lawyers argued, placed virtually zero value on GIPHY’s nascent display advertising business.
Towards the end of the last decade, the success of a handful of U.S. technology companies caused significant consternation amongst European policymakers. The initial response was a series of reports extrapolating new theories of harm in competition law for digital players. Some of these went even further, resulting in the creation of new regulatory regimes handing Government enforcers’ discretionary powers to intervene in the economy, with limited safeguards. In parallel, competition authorities stepped up enforcement using existing tools, resulting in a number of new enforcement actions at European and Member State levels, including former EU Member States.
As these competition cases are brought under judicial scrutiny, there are lessons to be learned for future policymakers, both in terms of the new theories of harm being tested, and the importance of checks and balances on administrative discretion. The UK Competition and Markets Authority (CMA) decision regarding Meta’s acquisition of GIPHY is one of the first such examples. The CMA’s decision has been heralded as opening up a “new era” of antitrust enforcement against tech, and is based on an innovative theory of harm to dynamic competition. But is this new era actually going to be good for consumers and the economy more broadly? At a hearing at the Competition Appeals Tribunal (CAT) at the end of April 2022, the parties and a handful of third-party interveners (including the Computer & Communications Industry Association) made their views known.
