The rise of containers has changed the way programmers think about developing, deploying and maintaining software applications. Using the capabilities of native isolation of modern operatingsystems, containers support a separation of concerns similar to virtual machines, but without consuming too many resources and greater deployment flexibility compared with virtual machines.
Containers are so lightweight and flexible that they have spawned new application architectures. This new approach consists of packaging the different services that make up an application in separate containers and then deploying those containers across a cluster of physical or virtual machines.
This blog post was inspired by a previous Kubernetes blog post about Advanced Server Side Apply. The author of said blog post listed multiple benefits for applications and controllers when switching to server-side apply (from now on abbreviated with SSA). Especially the chapter about CI/CD systems motivated me to respond and write down my thoughts and experiences.
These thoughts and experiences are the results of me working on Kluctl for the past 2 years. I describe Kluctl as "The missing glue to put together large Kubernetes deployments, composed of multiple smaller parts (Helm/Kustomize/...) in a manageable and unified way."

“Syslog is a way of consolidating logs from various systems to a remote Syslog server. The Syslog server has three key components. The first is a listener that utilizes UDP over port 514 to gather Syslog data. Next is the database that stores the generated Syslog data, and lastly, the management and filtering software that allows filtering the Syslog data for quick troubleshooting.
As a system administrator, understanding how Syslog works and how to configure client machines to channel their Syslog data to the remote server comes in handy. This guide discusses Syslog in Linux and offers steps for consolidating logs to a remote machine.”

The Masalla icon theme is a perfect choice for anyone looking to spruce up their Linux desktop. The theme comes with more than 15,000 different icons, including a wide variety of options for applications, devices, categories, places/folders, and much more. It’s also compatible with the most popular Linux desktops like Gnome, Cinnamon, Xfce, Unity, KDE, Mate, LXDE, and others.
If you have any interest in design, you’ve probably noticed that the current trend is ‘flat’ looks. And I absolutely love it! Hayder Majid, an Iraqi engineer, created this flat Masalla icon theme. The name of his project was “Obelisk” in Arabic and Uruk city (like the Obelisk of Hammurabi in the History of Iraq).
I had wanted to write about the Masalla icon theme for a long time because I really liked it. Unfortunately, there have been no updates from the developer in over 4 years. Recently, though, an updated version of Masalla was released 3 months ago.

Artificial intelligence and machine learning (AI/ML), often imagined as self-driving cars or human-like robots, are flourishing at the enterprise level as practical business use cases increase. Many companies rely on AI/ML to expedite internal processes, automate mundane tasks, and reduce human error.
But some businesses fail to consider that AI ethics are essential to ensure that the technology is used appropriately and securely and that it does not pose risks to businesses.
The growing importance of AI in nearly all enterprises brings into question how CIOs can ensure that the processes align with ethical and responsible AI. Because AI will likely continue to pave the way for additional technological advancements and is crucial to ensuring efficient and effective internal processes, CIOs and business leaders must pay attention to the following key pillars of ethical AI.
Open Source Experience is the meeting place for the entire open-source software industry. It gathers more than 4,500 professionals, allowing them to deep dive into open-source technologies, solutions and challenges in France and Europe. The event delves into topics like AI/ML, digital twins and Blockchain. Canonical is going to be present at OSXP Paris 2022, talking about Charmed Kubeflow, the end-to-end MLOps platform.
In Part I, we introduced and assessed the current status in the IT and OT domains. In Part II, we discussed the automation pyramid of modern factories and the need to adopt a more holistic approach toward closing the divide. In the final chapter of this three-part blog series, we will make a case for how adopting an enabling, open-source platform can help bridge the IT/OT divide and accelerate industrial transformation.
Ubuntu is the preferred operating system and an ideal enablement platform to bring the latest technological advances to the OT world. As the most widely used Linux distribution globally, the most deployed Linux web server on the internet and the most used Linux gaming distro, Ubuntu is the de-facto Linux standard in IT. After recognising and acknowledging the new wave of compute in Industrial, we created a flavour of Ubuntu to address the limitations of the OT world highlighted in Part I and Part II of this series.
We’ve seen two announcements of high-end RISC-V cores this week with the SiFive P670 and Andes AX65 processors each with a 4-way out-of-order people, but Alibaba’s T-Head Semiconductor Xuantie C908 is a little different with a dual-issued, 9-stage in-order pipeline and support for the RISC-V Vector extension acceleration targeting mid-range AIoT applications.
The C908 64-bit RISC-V core adopts the RV64GCB[V] instruction and complies with the RVA22 profile for better compatibility with Android and other “rich” operating systems. The company says its performance is between the C906 and C910 cores introduced in 2020 and 2019 respectively.
Disk Utility is a system utility for performing disk and disk volume-related tasks on macOS. We recommend the best free and open source alternatives.
In the Lua programming language, an array is called a table. A table is used in Lua to store data. If you're storing a lot of data in a structured way, it's useful to know your options for retrieving that data when you need it.
A new release 0.4.20 of RProtoBuf arrived on CRAN earlier today. RProtoBuf provides R with bindings for the Google Protocol Buffers (“ProtoBuf”) data encoding and serialization library used and released by Google, and deployed very widely in numerous projects as a language and operating-system agnostic protocol.
This release is somewhat mechanical and in the spirit of many other recent releases. clang-15 is, as more recent compilers do, more stringent on definitions and wants to see some void in argument-less signatures. Happy to oblige. At the same time, GitHub Actions started to nag us about minimum versions of node code so an upgrade to a newer action is warranted, again as with many other affected packages. We also found another http:// URL hiding somewhere so that was cleaned. Lastly, it appears Protocol Buffers themselves moved on and now need / prefer C++17 so were happy to oblige.
rbaron’s b-parasite is an open-source hardware Bluetooth LE plant watering sensor that can measure soil moisture and ambient temperature/humidity/light and works with ESPHome, Home Assistant, or any macOS or Linux platforms including the Raspberry Pi boards.
One reason why a company like Singtel Optus can leak customer data in a breach that is, by all accounts, its own fault and then avoid being held to account is because of the media's fawning coverage.
A typical example can be seen in Friday's Australian Financial Review, which carried an interview about what the Optus chairman Paul O’Sullivan has learnt from the breach. Of course, it's good to know that the man has learnt something.
For context, Optus has been dragged kicking and screaming to pledge that it would pay for replacing the passports that were leaked. Only this morning, the ABC reported that the company had been made to extend this to holders of foreign passports as well – after the matter had been ventilated on the 7.30 program.
The telco is still refusing to pay for the replacement of driving licences, only expressing a willingness to pay for the administration expenses associated with issuing these forms of ID.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has published three Industrial Control Systems (ICS) advisories about multiple vulnerabilities in software from ETIC Telecom, Nokia, and Delta Industrial Automation.
Prominent among them is a set of three flaws affecting ETIC Telecom's Remote Access Server (RAS), which "could allow an attacker to obtain sensitive information and compromise the vulnerable device and other connected machines," CISA said.
Today, November 4, 2022, marks two years since authorities implemented internet shutdowns in the Tigray region of Ethiopia. After 730 days, this must come to an end.
As peace talks between the government of Ethiopia and Tigray regional forces show positive signs of a ceasefire, this is the moment to reconnect all — everybody, from civil society to the African Union, has a responsibility to stand up and demand action.
“For two years — 730 days — millions of people in Tigray have been forced to survive through a horrific war, their circumstances exacerbated by a deliberate internet shutdown that prevents them from communicating with family and friends, accessing potentially life-saving information, and letting the world know what’s happening in their region,” said Felicia Anthonio, #KeepItOn Campaign Manager at Access Now. “Authorities must reconnect Tigray now.”
Tonight I paid for my first-ever official live music event. Not a free one, mind you. Fifteen dollars for entry, fifteen dollars well-spent for an entire night wherein the air became electric with sound, where the potential of humanity to channel emotion and effort into invisible audio waves became tangible.
I am considering the legitimacy of music journalism, its relationship with music, how well I can straddle both fields- production, mastering, composition, layering- a veritable balancing act. Journalism is, regardless of the others, a channel worthy of respect, of serious pursuit. It has gone from being a minor fascination of mine, a mere passing interest, into an obsession over which I would shell out $15 if I believed the band was worthy enough.
Life is scary right now - I'm not too sure about the future at all, and the past has a seductive iridescence to it - but it still feels correct to mark the small beautiful things like this. It probably snowed back at home weeks ago, but here, it's the first.
For those of us who are women with strong sex drives, comments that make universal declarations about the extent to which sexual interaction is a ‘real’ need is yet another instance of women being invalidated and told what our needs ‘should’ and ‘shouldn't’ be - and also, effectively, another form of slut-shaming.
A few days ago I noticed that my hiking shoes are really in need of some TLC. So, today I had a shoe-wax day, waxing all our hiking boots.
My wife and I each have two pairs of hiking boots, and one pair of hiking shoes. So, that means six pairs of shoes to wax, or twelve shoes.
This may appear like a very niche use case, in my quest of software conservancy for nixpkgs I didn't encounter many people understanding why I was doing this.
I would like to present you a project I made to easily download all the sources files required to build packages from nixpkgs, allowing to keep offline copies.
Why would you like to keep a local copy? If upstream disappear, you can't get access to the sources anymore, except maybe in Hydra, but you rely on a third party to access the sources, so it's still valuable to have local copies of software you care about, just to make copies. It's not that absolutely useful for everyone, but it's always important to have such tools available.
A frequent criticism of Gemini, and a topic that arises on Gemini itself from time to time, is that the protocol gatekeeps. Specifically, it has a barrier to entry for viewing content, and an even higher one for posting content. Szczeà ¼uja mentioned^ a recent discussion about the matter on Mastodon, and JeanG3nie gave a reply^^ yesterday that resonated with me.
In a way, talking about these issues on Gemini is a little self-defeating, and it's fresh meat for Gemini's detractors. "Gemini doesn't have a high barrier to entry", we say in our gemlogs, which the critics probably won't read because they don't want to install a client or use a proxy. The fact that they don't see the responses proves their point, right? That's all the convincing they need.
* Gemini (Primer) links can be opened using Gemini software. It's like the World Wide Web but a lot lighter.
