And here is the long 1h22min Krita video tutorial fully commented as I promised on the last blog post with the artwork.
It's a real full lenght course suited to beginners, but also advanced digital painters. It starts from scratch with default set of brushes, preferences and break-down all the process. The repetitive parts while painting were all accelerated and can be skipped easily (a timer in overlay appears on display) Check the Timeline codes under to navigate in the video.
Subtitle are unfortunately not available, sorry for my (heavy) French accent and poor vocabulary. It was too long to write them this time. I hope the auto generation will work and you'll have not a lot of trouble to understand me mumbling sometime.
It's been a couple years since the first Linux phone came out and I bought a Pinephone Pro in Jan of this year to follow back up on it.
In a two previous videos, I created a very simple GTK app using Haskell. In the first video, I created the app (which I named "byebye") in 30 minutes and I wrote it in such a way as to be as "gentle" an introduction to Haskell and GTK as I could be. In a second video, I refactored the code so it would be less lines and cleaner code. In this third video, I adding some new functionality to "byebye", namely the ability to read a config file and the ability to use CSS for theming.
What do Ryan DasGeek from @TuxDigital Jay from @Learn Linux TV have to say about buying hardware? "Buy native Linux hardware from vendors that actually ship Linux."

Linux creator Linus Torvalds has announced the first release candidate for the Linux kernel version 6.0, but he says the major number change doesn't signify anything especially different about this release.
While there is nothing fundamentally different about this release compared with 5.19, Torvalds noted that there were over 13,500 non-merge commits and over 800 merged commits, meaning "6.0 looks to be another fairly sizable release." According to Torvalds, most of the updates are improvements to the GPU, networking and sound.
Torvalds stuck to his word after releasing Linux kernel 5.19 last month, when he flagged he would likely call the next release 6.0 because he's "starting to worry about getting confused by big numbers again".

These GNOME apps are the development version of the native GNOME applications. They are usually unstable since its being developed and features are added continuously.
That means these apps you get to test and report any issues to the developers. Also, you get to experience the new features before it arrives in stable releases.
In this tutorial, we will show you how to install Darktable on Linux Mint 21. For those of you who didn’t know, Darktable is an open source photography workflow application and raw developer. It manages your digital negatives in a database, lets you view them through a zoomable lighttable, and enables you to develop raw images and enhance them. In addition to basic RAW conversion, Darktable is equipped with various tools for basic and advanced image editing.
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 a Darktable on Linux Mint 21 (Vanessa).
Salt or Saltstack is an open-source IT automation framework that allows administrators to execute commands remotely to multiple machines directly. Salt is mainly written in Python and designed with Master and Minion architecture. SaltStack master is the central controller of Salt configuration management, and Minions are servers managed by SaltStack Master, or you named minions as target servers.
SaltStack master is running on Linux OS by default, but minions can be any operating system. Saltstack is revolutionary configuration management for automation deployment, remote task execution, and infrastructure as code. SaltStack also can be used to provision multiple infrastructure servers, this includes physical and virtual servers, and also the cloud.
By following this guide, you will install SaltStack Master and Minion on Rocky Linux servers. Also, you will learn how to use Salt for running Arbitrary commands from SaltStack Master against Salt Minions. And at the end, you will also learn how to create a Salt state for installing the basic LEMP Stack (Linux, Nginx, MariaDB, and PHP-FPM).
We have already discussed the gzip command in Linux. For starters, the tool is used to compress or expand files. To uncompress, the command offers a command line option -d. However, there's an entirely different tool that you can use for uncompressing or expanding archives created by gzip. The tool in question is gunzip. In this article, we will discuss the gunzip command using some easy to understand examples.

This month I’ve been pondering offline-first apps. The online aspect of modern apps is an important feature for many use-cases: it enables collaboration between multiple people and seamless transition between devices (e.g. I often switch between my personal workstation, my laptop, and my phone). However many modern apps come with a cost: often times they only work with a fixed proprietary server, and only work online. I think that for many use-cases, allowing users to pick their own open-source server instance and designing offline-friendly apps is a good compromise between freedom and ease-of-use/simplicity. Not to say that peer-to-peer or fully distributed apps are always a bad choice, but they come at a significantly higher complexity cost, which makes them more annoying to both build and use.
The main hurdle when writing an offline-first app is synchronization. All devices must have a local copy of the database for offline use, and they need to push changes to the server when the device comes online. Of course, it’s perfectly possible that changes were made on multiple devices while offline, so some kind of conflict resolution is necessary. Instead of presenting a “Oops, we’ve got a conflict, which version would you like to keep?” dialog to the user, it’d be much nicer to just Do The Right Thing™. CRDTs are a solution to that problem. They look a bit scary at first because of all of the obscure naming (PN-Counter? LWW-Element-Set? anyone?) and intimidating theory in papers. However I like to think of CRDTs as “use this one easy trick to make synchronization work well”, and not some kind of complicated abstract machinery. In other words, by following some simple rules, it’s not too difficult to write well-behaved synchronization logic.
So, long story short, I’ve been experimenting with CRDTs this month. To get some hands-on experience, I’ve started working on a small hacky group expense tracking app, seda. I’ve got the idea for this NPotM while realizing that there’s no existing good open-source user-friendly collaborative offline-capable (!) alternative yet. That said, it’s just a toy for now, nothing serious yet. If you want to play with it, you can have a look at the demo (feel free to toggle offline mode in the dev tools, then make some changes, then go online). There’s still a lot to be done: in particular, things gets a bit hairy when one device deletes a participant and another creates a transaction with that user at the same time. I plan to write some docs and maybe a blog post about my findings.
As my favourite software lecturer used to say, it’s better to be clear than clever. He was talking about code reviews, but it easily applies to tasks you assign yourself. We all think we’re clever, but “do X” in your task manager feels far less intimidating if it has “do A, B, and C” subtasks underneath.
Few tools walk the right line between declarative and imperative like make.
The past weekend contained two full days of the second Raku Conference.
While C++ is the pioneer of object-oriented languages, Python is one of the newer languages that has hit peak popularity due to its easy-to-understand syntax, among a ton of other benefits. That said, it is valid to draw a comparison between C++ vs Python as they are both high-level programming languages with similar uses.
Although one can use both languages to develop real-time dynamic applications, C++ and Python can be seen to go on different paths as most prefer C++ for general applications, and Python users often get a kick out of developing web applications. If this piques your interest or if you are trying to choose which to learn, stick on because that’s why we are here today!
Your clients are global, and they expect to have access to the skills of your staff globally as well. Even when workers are collaborating remotely, there must be no interruptions. Even though your organization purchased licenses for everyone to use a video conferencing program, nobody feels as if they are cooperating properly. How can businesses engage remote workers and consumers who want experiences that are given “now here, right now” and without any delays or interruptions?

If you’re not aware of WebRTC, it allows for native real-time media connections between devices and browsers, including audio, video, and data transmission. As a result, users may instantaneously interact inside a web browser or app without the need for complicated plug-ins or other applications.
My recent Walkman post generated a ton of email and comments; thanks to most of you for sharing your ideas and questions!
I say most, because it seemed to attract more trolls than anything I’ve written in a long time. It’s disheartening to have something you enjoyed (and tried to share with people) immediately shat on by those who don’t even bother to read it. At times it makes me wonder why I even blog in the first place; but then I remember all the rest of you :).
Jetway says the thin mini-ITX networking board support Windows 10, Windows 11, and Linux, and recommends models with the 32GB eMMC flash to boot Windows 10 for some reasons… Looking into the datasheet, we find a longer list of operating systems, even adding some BSD distributions with Win10 64-bit, Win 10 IoT Enterprise 64-bit LTSC 2019, CentOS (Version 9), Debian (Version 11.3), Fedora LXDE, Workstation, or Server (Version 36.1.5), OpenSUSE (Version 15.4), Ubuntu 22.04 Desktop/Server, pfSense (Version 2.6.0), TrueNAS (FreeNAS) (Version 13.0), RedHat Enterprise (Version 9.0), and OPNSense (Version 22.1.2).
From my own experience, as a person and a family that enjoys visiting wilderness areas, having radio communication is great. I have also heard from others that they’re also very useful on cruise ships (I’ve never been on one so I can’t attest to that).
There is also a sheer satisfaction in not needing anybody else’s infrastructure, not paying any sort of monthly fee, and setting up the radios ourselves.
Air pollution is not just a problem for lungs. Increasingly, research suggests air pollution can influence childhood behavioral problems and even IQ. A new study led by the University of Washington has added evidence showing that both prenatal and postnatal exposure to air pollution can harm kids.
The study, published in Environmental Health Perspectives, found that children whose mothers experienced higher nitrogen dioxide (NO2) exposure during pregnancy, particularly in the first and second trimester, were more likely to have behavioral problems.
Later on, MS abused that power repeatedly, stole code, copied ideas, unfairly pushed rivals out of business, and generally became a bully and a criminal. MS effectively killed Be, Netscape, and Central Point Software; it crippled Aldus and STAC; and many more.
Google is once again boosting the maximum bounty payouts for Linux vulnerabilities reported as part of its open-source Kubernetes-based capture-the-flag (CTF) vulnerability rewards program (VRP).
Called kCTF, the program was launched in 2020 to provide security researchers with the means to report vulnerabilities in the Google Kubernetes Engine (GKE), for which they receive a flag.
“All of GKE and its dependencies are in scope, but every flag caught so far has been a container breakout through a Linux kernel vulnerability. We’ve learned that finding and exploiting heap memory corruption vulnerabilities in the Linux kernel could be made a lot harder,” Google notes.
The PostgreSQL JDBC team have released 42.2.26 and 42.4.1 to address a security issue: CVE-2022-31197. This is only an issue if you are using ResultSet.refreshRow()
Previously, the column names for both key and data columns in the table were copied as-is into the generated SQL. This allowed a malicious table with column names that include statement terminator to be parsed and executed as multiple separate commands.

Scammers were able to convince YouTube that other peoples’ music was their own. They successfully stole $23 million before they were caught.
No one knows how common this scam is, and how much money total is being stolen in this way. Presumably this is not an uncommon fraud.
The biggest fallacy in the online privacy is that there is a difference between "state surveillance" and "commercial surveillance." Bizarrely, it's a fallacy that is widely held by both government snoops and Big Tech snoops.
Many's the time I've spoken to a DC audience about privacy, only to have an audience member say, "I'm OK with Uncle Sam spying on me – after all, I've already given up every sensitive scrap of information about my personal life to the Office of Personnel Management when I applied for security clearance. But I don't want my money going to Google – those bastards would sell their mothers out for a nickle."
Meanwhile, in Silicon Valley, I hear, "I don't care if Google has my data – they just want to show me better ads. But the US government? Hell no! Those govies and their profiteering private contractor pals are all too stupid to get jobs at real tech companies and who knows what they're going to do with my data?"
Anti-queer hate crimes are at an all-time high. Murders of transgender and gender-nonconforming people have skyrocketed year over year since 2016.
Considering these facts, NFTs may be just the last Ponzi scheme to part fools from their money, which in too many cases they are just that. Ditto for another buzzword of the moment, the so-called “metaverse”.
With inflation high, public spending and central bank ‘money printing’ has become the scapegoat, leading to calls for spending cuts and/or higher interest rates to combat it. This not only overlooks how inflation is being driven primarily by supply shocks beyond our immediate control, but also the fact that most of the money in our economy is not ‘printed’ by the state, but created by private banks when they make loans – the vast majority of which goes towards bidding up the price of existing assets (including commodities we rely on) rather than increasing the economy’s productive capacity.
Even when the rich and powerful fall out, the house – their wealth – always wins. Michael Sainsbury examines the latest goings on surrounding Sydney’s Crown Casino.
The grubby nexus between Australian business, politics and the mainstream media has been laid bare in a leaked series of explosive emails from James Packer to senior Nine Entertainment executives, journalists and chairman Peter Costello.
The emails alleged that Costello was paid as a secret Crown lobbyist in 2011 for a year, a claim he denies.
Packer said that Costello’s role was to bring Packer “closer” to then Victorian gaming minister Michael O’Brien, his friend and former staffer. The job was undertaken while Costello was on the board of Future Fund and not disclosed on the national lobbyist register. He was elevated to Future Fund chair in 2014 and remains in the position which would also seem at odds with his role at Nine.
Why is Scott Morrison hanging around? The weekend revelations that Morrison swore himself in to multiple portfolios without notifying the nation has sparked cries of outrage, in the political class at least.
Morrison had himself sworn in as a spare health minister during the first months of the Covid pandemic and also held the finance and resources portfolios during different periods in 2020 and 2021.
I just got back from work after summer vacation. I say work, but it's really just a paid internship. School starts again in 3 weeks, and I cannot wait. This job is so boring, and I feel so unwelcome. At the same time, I do get paid, so I feel like I can't be too ungrateful. It's a big industry, and it always comes down to "Who can take care of the intern" and everyone looks down and avoids eye contact. I feel like I just get in people's way. Anyhow, It's good money for someone who hasn't really made any on their own.
I want to go back to school, finish my education and start life for real. It feels like life is in some kind of transition state, just waiting for something real to begin. I have yet to figure out what, but I just yearn for something new, something to take me somewhere I've never been before, somewhere interesting.
My newest laptop is a refurbished 2-in-1 I got from a friend. A few of the keys are finicky, and he needed to type reliably for his job. He gave it to me, since I had worked on his other computers before. The work? Installing Linux on every one of his machines. He's far from tech-savvy; he just got fed up with the eternal update cycle and vows never to return to Windows. Anytime he gets a new computer he calls me up to ask me to install Linux for him: even when I'm on the other side of the world.
It's currently my main laptop. It's the fastest computer I have, so it's used for watching videos, compiling software, and playing video games.

So, this book is about the incredible ways in which other animals sense the world around us. At the core of it is a concept called Umwelt, the idea that each creature has its own sensory bubble...
In this article, I go over some improvements from our previous venture with borgmatic and snapper. My previous (and rather janky) approach was not only unnecessary but inefficient. As borg caches based on absolute filepaths, having a stable location is superior to changing it everytime. Further, if you are backing up multiple users (even if it's just root and your own user), it's probably best to run all the scripts as root. Permissions will be preserved, so you shouldn't have to worry about that (though you need root to extract the archives obviously).
