GTK: At the Heart of GNOME

Filed under
Development
GNOME

GTK is at the heart of the GNOME application and software development kit. GTK is used to create graphical user interfaces (GUIs) for desktop environments, applications, and window managers. Since the GTK 4 development process began in 2016, we have about 250 individual contributors, with more than 100 active this year.

Thanks to the funding received by the GNOME Foundation in 2020, the GTK development team was able to run hackfests, including one we were lucky enough to have at FOSDEM. This funding also supported Emmanuele Bassi, Core GTK Developer at the GNOME Foundation, working on GTK full-time. For most of 2020, Emmanuele worked on implementing a new accessibility interface for GTK 4, to ensure that more people can use GNOME applications, including those with disabilities. We are building a diverse and sustainable free software computing ecosystem where everyone can be empowered by technology they trust. Since Emmanuele works directly for the Foundation he’s uniquely able to focus on the needs of the community, project, and users to support these goals.

GTK is a project with a long history, and throughout that history, it has gone through multiple iterations. A new major release is on the horizon. After four years of development that included a complete overhaul of the internals of the toolkit, GTK 4 promises to be faster through hardware acceleration; more efficient, in terms of performance and power consumption; and more ergonomic, for both application developers, and end users. Over the past four years, the GTK team has continued work on the existing stable versions of GTK and put out multiple releases.

Platform exclusivity, DRM, and independent authors: A cautionary tale

Filed under
GNU

Imagine, for the sake of argument, that you wrote a book. You've worked on it for years, and you want to share it with the world. You want to reach as many people as possible, but it would be nice to be compensated for your hard work. How many weekends did you spend at home, polishing your manuscript instead of going out with friends? How many sleepless nights have you spent staring at a blank page, looking for inspiration?

While researching the best way to publish, you hear horror stories about authors finding their books sold on counterfeit Web sites or distributed gratis without the author's consent. You read stories about authors feeling violated as their hard work is stolen in such a way.

As you read about these activities, you also see mentions of companies that claim that they would protect your work against it. Should you publish your book through them, your book would only be available through their application. People could only access it through their store, and they wouldn't even be able to open the file on a device that isn't vetted by the company. The app is very popular, so most people use it anyway, and authors do not have to worry about a lack of interest. Only dealing with one store would also make things easier on your end. You won't have to manage different things. They'll even format your book for you. Sounds easy enough, so you take the deal.

Weeks pass, and you make a few sales. It's by no mean a huge success, but you got a few positive reviews, mostly from family and friends. You keep mentioning your project to everyone you know, and find some limited interest.

One day, a friend you hadn't talked to in a while asks about your book. They say that they don't like the app your book requires, and they don't want to buy it through the one store you signed an exclusivity deal with. They explain that Digital Restrictions Management (DRM) restricts their freedom to read the book on their device of choice, and won't even let them make backups of the file. They tell you how they once used a similar app, but were locked out of all the books they purchased after moving away from said application.

After hearing your friend's story, you decide to give them a DRM-free copy of your book. After all, you wrote it so people would enjoy it first and foremost, and you want your friend to see the fruit of your labor.

  • Arduino Blog » This remote-controlled storytelling apparatus is made up of Arduino-driven toy animatronics

    As an exhibit at the Phaneo Science Center in Wolfsburg, Germany, Niklas Roy and Felix Figus created a remotely-operated storytelling apparatus dubbed “Smart Fairy Tale.”

    When initiated, a little red ball rolls down the installation’s transparent tubing, triggering different interactions based on the interruption of light sensors along its path. 25 Arduino Nanos are used to control each individual animatronic part of the “story,” making the code manageable and allowing the overall machine to still work if there’s a malfunction in one section.

  • Pine64's PINECIL RISC-V soldering iron launched for $25

Linux READFILE System Call Revived Now That It Might Have A User

Filed under
Linux

Earlier this year we mentioned Greg Kroah-Hartman working on a new READFILE system call. The goal of this new syscall is for reading small and medium files more efficiently by having one call to read a file straight into a buffer without having to use the separate open/read/close system calls. It's looking like that system call is back on the table and could be mainlined now that there's a possible user.

The READFILE system call is simple for reading lightweight files straight into a buffer without the overhead of multiple system calls that in turn can help performance, especially if reading many files such as on sysfs/debugfs and the like.

It had been a number of months without any updates on that syscall and it wasn't mainlined in the cycles since it was proposed earlier this year. But now it looks like it's back on the table.

  • Communication by example: Which methods do high-performing open source communities use?

    Although effective communication is an essential life skill, it is the most critical element in any business [2]. Lack of accurate communication is the common cause of any organization’s issues, causing conflicts, reducing client relationships, team effectiveness, and profitability [2]. According to the Project Management Institute (PMI), ineffective communication is the main contributor to project failure one-third of the time. It has a negative impact on project success more than half of the time [1].

    In open source projects where there is a diverse and world spread community, effective communication is the key to projects’ success. Using the right technology is crucial for that. So, which tools do open source communities use for communication?

The 10 Best Linux Backup Tools

Filed under
Software

If you are a high-end software developer, system admin, or content creator who changed their Alien ID to the Linux world, then this article piece is for you. There is no worse enemy to a committed Linux enthusiast than data loss. To deal with data loss, you must understand the essential services of backup tools software.

You might be thinking, well, my machine system has several partitions. One has my Linux operating system installed, and the remaining ones I use to back up the data that I continuously use and develop. Moreover, you might be considerate enough to acquire an external hard disk drive to store your important files. However, the game of data loss is like playing chess against a supercomputer. The odds are never in our favor. It is usually when everything is going smoothly that an unfortunate event tends to introduce itself.

An unstable surge could occur and put your entire machine system in an ICU state. Such circumstances tend to corrupt or put your important data in an irretrievable state. Furthermore, a filled coffee mug that puts your ingenious mind in an active and productive state could accidentally spill on your machine or external HDD and commit the highest level of treason. This coffee that keeps our minds awake could have the opposite effect on our machines and any other external storage devices. Worse still, you will be forced to stay awake the whole night to mourn your data loss because the dark shades of coffee you took are still in your system.

    When people approach me to talk about Podman and containers, I usually ask if they are familiar with Docker. Most people are, and the conversations quickly move beyond the fact that Podman can act as a drop-in replacement for Docker. In fact, there are many useful and innovative features that make Podman special. Podman has excellent rootless support, it can generate systemd unit files for easily containerizing systemd services, and it has a powerful RESTful API that allows for running Podman on macOS and Windows. Those are just a few of the great features.

    Today you can find hundreds of emulators for dozens of old systems for multiple platforms. However, Dolphin manages to stand out from the crowd by achieving something almost impossible: combining advanced features and a high degree of compatibility with ease of use.

    With Dolphin, which is available for Windows, macOS, Linux, and Android, you gain access to the vast majority of titles for Nintendo’s GameCube and Wii consoles. Theoretically, since it’s easy to use, you only have to run it, add some games, and play. Practically, though, it’s worth investing some time to customize and configure Dolphin to your liking. This way, you’ll be able to take advantage of its advanced features and play your games better than you would on the actual hardware.

  • Terminal Vitality

    Ever since Douglas Engelbart flipped over a trackball and discovered a mouse, our interactions with computers have shifted from linguistics to hieroglyphics. That is, instead of typing commands at a prompt in what we now call a Command Line Interface (CLI), we click little icons and drag them to other little icons to guide our machines to perform the tasks we desire.

    Apple led the way to commercialization of this concept we now call the Graphical User Interface (GUI), replacing its pioneering and mostly keyboard-driven Apple // microcomputer with the original GUI-only Macintosh. After quickly responding with an almost unusable Windows 1.0 release, Microsoft piled on in later versions with the Start menu and push button toolbars that together solidified mouse-driven operating systems as the default interface for the rest of us. Linux, along with its inspiration Unix, had long championed many users running many programs simultaneously through an insanely powerful CLI. It thus joined the GUI party late with its likewise insanely powerful yet famously insecure X-Windows framework and the many GUIs such as KDE and Gnome that it eventually supported.

  • Create a machine learning model with Bash | Opensource.com

    Machine learning is a powerful computing capability for predicting or forecasting things that conventional algorithms find challenging. The machine learning journey begins with collecting and preparing data—a lot of it—then it builds mathematical models based on that data. While multiple tools can be used for these tasks, I like to use the shell.

    A shell is an interface for performing operations using a defined language. This language can be invoked interactively or scripted. The concept of the shell was introduced in Unix operating systems in the 1970s. Some of the most popular shells include Bash, tcsh, and Zsh. They are available for all operating systems, including Linux, macOS, and Windows, which gives them high portability. For this exercise, I'll use Bash.

  • Adam Williamson: Site and blog migration

    So I've been having an adventurous week here at HA Towers: I decided, after something more than a decade, I'm going to get out of the self-hosting game, as far as I can. It makes me a bit sad, because it's been kinda cool to do and I think it's worked pretty well, but I'm getting to a point where it seems silly that a small part of me has to constantly be concerned with making sure my web and mail servers and all the rest of it keep working, when the services exist to do it much more efficiently. It's cool that it's still possible to do it, but I don't think I need to actually do it any more.

    So, if you're reading this...and I didn't do something really weird...it's not being served to you by a Fedora system three feet from my desk any more. It's being served to you by a server owned by a commodity web hoster...somewhere in North America...running Lightspeed (boo) on who knows what OS. I pre-paid for four years of hosting before realizing they were running proprietary software, and I figured what the hell, it's just a web serving serving static files. If it starts to really bug me I'll move it, and hopefully you'll never notice.

    [...]

    I also set up a Kolab Now account and switched my contacts and calendar to it, which was nice and easy to do (download the ICS files from Radicale, upload them to Kolab, switch my accounts on my laptops and phone, shut down the Radicale server, done). I also plan to have it serve my mail, but that migration is going to be the longest and most complicated as I'll have to move several gigs of mail and re-do all my filters. Fun!

  • 2020.47 Present Release – Rakudo Weekly News

Plus some efficiency improvements and quite a number of bug fixes and improvements.

    Sadly, shortly after the release it became clear that some typical workloads seem to be affected by a noticeable performance regression. This appears to be caused by the new coercion semantics inadvertently disabling some runtime optimizations. Fixing this has now become a blocker for the next release. It just goes to show that in Raku, it’s important to first make it work, and then make it work fast. And that a lot of users are already relying on those runtime optimizations.

  • The Internet Archive are keeping Flash creations alive with the open source Ruffle

    Like many of you, I have certain fond memories of playing various Flash games many years ago. There's obviously many better ways to do web games now and Adobe are killing Flash in December.

    On December 31, Adobe will be cutting off Flash from any further updates, it will effectively be End Of Life. There's a few projects around trying to keep it alive, like the open source Ruffle emulator written in Rust. Ruffle is still in development but even so the results are impressive, and it can already play thousands of Flash items. All you need is an up to date browser and it does it all for you with no plugins needed. If you have any Flash stuff, you can even test it online.

    Seems people have taken notice of this effort, like The Internet Archive who are known rather well for their Wayback Machine that stores websites at various dates. Announced in a blog post on November 19, the archive's Jason Scott announced that they're now storing and emulating various Flash animations, games and toys in their growing collection.

  • Apple head of security accused of offering iPads as bribes for concealed gun permits

    A California grand jury has indicted Apple’s head of global security on charges that he tried to bribe Santa Clara County officials to procure firearms (CCW) licenses, according to a news release. Santa Clara district attorney Jeff Rosen alleges that Thomas Moyer offered 200 iPads — worth about $70,000 — to Capt. James Jensen and Undersheriff Rick Sung in the Santa Clara County sheriff’s office, in exchange for four concealed firearms licenses for Apple employees.

    The charges came after a two-year investigation. “In the case of four CCW licenses withheld from Apple employees, Undersheriff Sung and Cpt. Jensen managed to extract from Thomas Moyer a promise that Apple would donate iPads to the Sheriff’s Office,” Rosen said in the news release. The iPads were never delivered, according to Rosen’s office, because Sung and Moyer became aware in 2019 that the district attorney was executing a search warrant for the sheriff department’s CCW records.

    We tested 11 different doorbells found on eBay and Amazon, many of which had scores of 5-star reviews, were recommended as ‘Amazon’s Choice’, or on the bestseller list. One was labelled as the number one bestseller in ‘door viewers’. We found vulnerabilities with every single one.

  • Homemade recycling rig turns plastic waste into new products

    While that plastic cup, bag, dish, or other item may have served its purpose, more than likely it could be formed into something new. With this in mind, the SOTOP-Recycling team of Manuel Maeder, Benjamin Krause, and Nadina Maeder developed an automated injection molding machine that can be built at home and is small enough to allow you to run your own recycling operation!

    Everything is controlled by an Arduino Mega.

  • Delock MQTT-enabled power socket switches

    The included leaflet is sufficient to get started. Plugging the device into mains has it create a WiFi access point I connect to, and I can then configure it to connect to my home network. The Tasmota firmware spoke German to me all the time, and the only reason I can think of, as my browsers are all set to English, is that it was built that way for delivery here. Ronald confirms that and explains I can flash the device with an en firmware from here (I pasted the link to tasmota.bin into the firmware update page).

  • [Old] The Finfisher Tales, Chapter 1: The dropper

    Amnesty International finally dropped the bomb and released a report about FinSpy spyware made by FinFisher Gmbh.

    The most interesting thing was the revelation of Mac and Linux versions, something that was missing from previous reports on this commercial malware (Kaspersky, Wikileaks).

    Their report summarizes the most important features but isn’t technically deep. This got me interested in verifying if FinSpy for Mac was any good malicious software or just the same kind of bullshit commercial malware like HackingTeam (they finally went kaput, oh so many crocodile tears!).

  • Aerofly FS 2 Flight Simulator from IPACS is now available on Linux | GamingOnLinux

    Need to take to the skies? We can possibly help with that. Aerofly FS 2 Flight Simulator from IPACS recently quitely released a Linux version. They don't seem to have announced it in a news post but it's up and live on Steam right now. A reader emailed in about this, and the developer has confirmed it on their Steam forum.

    Looks like quite a detailed flight sim too with a number of aircraft included like the A320, B737-500, F-15, F-18, Aermacchi MB-339, King Air C90 GTx, Learjet 45, ASG 29 and Swift S1 gliders and more. After being released in Early Access in 2016, then a full release in 2017 it's continued being supported for a long time now. Most recently, it had a big update adding in the EC135 helicopter along with a bunch of optimizations to the game.

  • Amnesia: Rebirth is easily one of the scariest and best games of 2020

    After a rough launch, Frictional Games have nicely fixed up Amnesia: Rebirth and overall the experience is one we're not going to forget any time soon.

    "In Amnesia: Rebirth, you are Tasi Trianon, waking up deep in the desert of Algeria. Days have passed. Where have you been? What did you do? Where are the others? Retrace your journey, pull together the fragments of your shattered past; it is your only chance to survive the pitiless horror that threatens to devour you."

    While our livestreamer did a full playthrough live on our Twitch Channel cheered on by viewers which you can watch through on-demand on our YouTube Channel, I was spending it entirely alone in a dark room with no one but myself to count on. Not the best idea, because I am a complete wimp. I'm at least honest about that though and Amnesia: Rebirth was, in a word, terrifying. Okay, not all the way through, but plenty of it was.

    Amnesia: Rebirth might be Frictional's weirdest yet too. All of their games are strange in their own way but it feels like they really went hard on the darkness in Amnesia: Rebirth. It worked well though, not many games have made me terrified to look at a tiny window on a door before while I search a room for anything useful to keep me going that little bit longer.

  • Deep survival game Vintage Story has my full attention with the latest expansion

    Vintage Story has a huge new version almost ready to release, with a couple of Release Candidates going up for the 1.14 release and it's looking awesome.

    This is the survival game for those of you who love the blocky style of Minecraft but want something deeper, something much more complex and exciting. With full Linux support, Vintage Story is a good choice and the developer is definitely dedicated to their idea.

    With the 1.14 update pulling in lots of often requested features including character customization, the "Steel Age" along with assorted items to build like a metal door and a mechanical powered Pulverizer building that can grind down things for you which looks awesome. Your body temperature now matters more too with clothing giving warmth, frost damage during harsh winters, lots of new blocks, new graphics with shader effects and lots more.
