GIMP 2.10.14 Released

Filed under
GNU
Software

This is basically the first shot at the previously missing feature set, so expect more to land to GIMP at some point in the future. Making selection tools work outside the canvas sounds like a sensible next stop. Then maybe we can seriously talk about boundless canvas.

This new feature is closely related to out-of-canvas viewing and editing and was also contributed by Ell.

Now when you e.g. rotate a single-layer image, you can use this transform type to automatically expand the canvas to include all of rotated pixels when using the default Adjust clipping mode. The switch is right next to layer/path/selection toggle at the top of any transform tool’s settings.

i.MX8M and i.MX8M Mini SMARC modules debut with 3.5-inch carrier

Filed under
Linux

Ibase’s rugged “RM-N8M” SMARC module runs Linux on an i.MX8M with 3GB soldered LPDDR4 and up to 64GB eMMC. There’s also an upcoming “RM-N8MMI” SMARC that taps the i.MX8M Mini and a new 3.5-inch “RP-103-SMC” carrier.

Ibase announced an RM-N8M Series SMARC 2.0 form-factor module equipped with an NXP i.MX8M SoC. While poking around the Ibase website to see if the company had launched any previous SMARC modules, we found that indeed there is an i.MX6-based RM-F6 SMARC 1.0 module. We also saw a “preliminary” RM-N8MMI Series SMARC 2.0 module with an i.MX8M Mini that we cover farther below.

Native GTK Dialogs in LibreOffice

Filed under
LibO

The LibreOffice UI was traditionally implemented with its own VCL toolkit which via theming emulated the host desktop toolkit.

Then we migrated the file format the dialogs were described in to the GtkBuilder file format. But still implemented with VCL widgetry, though with additional GTK-alike layout widgets.

Then migrated the translation format to gettext .mo files, which added plural form translation support we had lacked.

Then incrementally migrated the code driving the dialogs to a new API with two implementations, one for VCL widgetry and one for GTK.

Over the last few major releases the GTK version of LibreOffice has increasingly had true GTK dialogs and less VCL dialogs and in master, as of this week, there are now no direct uses of the VCL dialog APIs.

  • Rugged embedded trio run Linux on Whiskey Lake

    Vecow launched two compact, rugged embedded PCs with Intel's 8th Gen Whiskey Lake-UE. The Linux-ready SPC-5000 and -5100 offer 4x 10Gbps USB 3.1 Gen2 ports and SUMIT expansion with optional 10GbE modules, and the RES-3000 features IP67-protected M12 ports.

    Vecow announced a fanless, rugged SPC-5000 computer and almost identical, but wider-temp SPC-5100, equipped with Intel's 8th Gen Whiskey Lake-UE CPU. Both embedded computers target machine vision, in-vehicle computing, factory automation, ITS, intelligent control, and AIoT/Industry 4.0 applications.

    The SPC-5000/5100 systems appear to be based on Vecow's recently launched, 3.5-inch EMBC-3000 SBC. The EMBC-3000 also powers a larger, more feature-rich SPC-5200 computer that was announced at the same time in early September.

  • Top opensource Android apps

    Since my transition to Linux I have acquired a culture of open source software, a culture that is expanding with every day I spend in Linux. 

    Especially after having seen the importance of open source applications in fighting the monopoly of Big softwares companies such as Microsoft, Apple, Adobe ...

    It has expanded to include even the way I use my smartphone, where I have become inclined to use open source applications, because of my love for open source on the one hand, and on the other hand because of the thirst of commercial software to spy on my personal information as well as the aggressive bad ads that hinder the good use of softwares. 

  • GraphQL a cut above the REST, say query lang's fans: Airbnb, Knotel, others embrace the tech

    At the GraphQL Summit in San Francisco on Wednesday, Matt DeBergalis, co-founder and CTO at data plumbing biz Apollo GraphQL, urged companies to appoint a data graph champion to help ease the implementation of GraphQL, a query language for fetching data.

    It's not yet a given that organizations want to implement GraphQL. But at a gathering arranged by Apollo, which makes the de facto standard open-source client and the commercial Apollo GraphQL Platform, there's a certain incentive to imagine GraphQL everywhere.

    It's already halfway there, at least among the 472 companies attending the show – about 52 per cent of organizations represented are already using the technology in production. Some of the more recognizable names include Airbnb, Audi, Expedia, The New York Times, Medium, PayPal, and Priceline.

  • After Server Breach, NordVPN Has Strengthened Security Measures

    What do you do when you find out the company you were entrusting with your privacy was hacked? Panic? There may have been a lot of that going on when NordVPN admitted to a security breach of their server.

    The good news is that NordVPN is on top of it, and it has already strengthened security measures. But will they be able to trust NordVPN again?

  • Shadow tree encapsulation theory

    Types 3 through 5 do not have any kind of support and type 4 and 5 encapsulation would be hard to pull off due to Spectre. User agents typically use a weaker variant of type 4 for their internal controls, such as the video and input elements, that does not protect confidentiality.

    [...]

    Type 2 encapsulation gives component developers control over what remains encapsulated and what is exposed. You need to take all your users into account and expose the best possible public API for them. At the same time, it protects you from folks taking a dependency on the guts of the component. Aspects you might want to refactor or add functionality to over time. This is much harder with type 1 encapsulation as there will be APIs that can reach into the details of your component and if users do so you cannot refactor it without updating all the callers.

  • Configurama - Building SaaS #36

    In this episode, we turned our attention to handling settings and configuration. We discussed different techniques for handling settings, looked at available tools, and started integrating one of the tools into the project.

    The initial discussion in the stream focused on different ways of doing settings. I talked about what I view as a difference between configuration (mostly static stuff) and settings (dynamic parts of the app).

    I also discussed where to get settings from. We talked about the 12 Factor App style with environment variables, and secret management tools like HashiCorp Vault and AWS KMS. Ironically, I blanked out on AWS Secrets Manager as an option. Additionally, we considered the alternative of reading settings from a file instead of environment variables and the security implications of environment variables.

Red Hat: Kubernetes, RHEL Impact and Halloween Release

Filed under
Red Hat
  • Why you don't have to be afraid of Kubernetes

    It was fun to work at a large web property in the late 1990s and early 2000s. My experience takes me back to American Greetings Interactive, where on Valentine's Day, we had one of the top 10 sites on the internet (measured by web traffic). We delivered e-cards for AmericanGreetings.com, BlueMountain.com, and others, as well as providing e-cards for partners like MSN and AOL. Veterans of the organization fondly remember epic stories of doing great battle with other e-card sites like Hallmark. As an aside, I also ran large web properties for Holly Hobbie, Care Bears, and Strawberry Shortcake.

    I remember like it was yesterday the first time we had a real problem. Normally, we had about 200Mbps of traffic coming in our front doors (routers, firewalls, and load balancers). But, suddenly, out of nowhere, the Multi Router Traffic Grapher (MRTG) graphs spiked to 2Gbps in a few minutes. I was running around, scrambling like crazy. I understood our entire technology stack, from the routers, switches, firewalls, and load balancers, to the Linux/Apache web servers, to our Python stack (a meta version of FastCGI), and the Network File System (NFS) servers. I knew where all of the config files were, I had access to all of the admin interfaces, and I was a seasoned, battle-hardened sysadmin with years of experience troubleshooting complex problems.

    But, I couldn't figure out what was happening...

    Five minutes feels like an eternity when you are frantically typing commands across a thousand Linux servers. I knew the site was going to go down any second because it's fairly easy to overwhelm a thousand-node cluster when it's divided up and compartmentalized into smaller clusters.

  • The economic impact of Red Hat Enterprise Linux: How IT professionals benefit

    It’s not overstated to say that the IT landscape completely changed with the introduction of Red Hat Enterprise Linux, more than a decade and a half ago. For 2019, IDC estimated a global business revenue of $188 trillion. Of this, they estimate that at least 40% is touched by software, leaving the IT footprint to be an estimated $81 trillion. Yes, you read that right, $81 trillion. As all of this software forming the global business IT footprint has to run on an operating system, IDC estimates that over 50% is running on Linux, with Red Hat Enterprise Linux accounting for 25% of that.

    That’s a lot of big numbers but what does it all mean? It means that Red Hat Enterprise Linux has changed the experience of many IT professionals around the globe. In a software-centric world, ongoing we have seen higher demand in support and IT services which in turn further helps fuel the global IT ecosystem.

    When IDC asked IT organizations how Red Hat Enterprise Linux benefitted them, they discovered a 12% savings in IT staff productivity. This means that IT professionals spend less time managing servers, doing routine IT tasks, resolving support calls, deploying new business apps and upgrading mission-critical apps. But that’s not all.

  • The spooktacular tale of Red Hat's Halloween release

    In many stories and myths, naming is important. Knowing the proper name of something gives you power over it. Likewise, naming has been important for Red Hat Linux over the years.

    The Halloween release was actually a paid beta and not a 1.0. The Halloween release was dubbed Red Hat Software Linux 0.9, and started a tradition of having a codename for the release that lasted through the final Red Hat Linux release (9.0.93, "Severn"), and carried over to Fedora for many years.

    The tradition was to have a name for a release that was somewhat related to the previous release name. For example, the 1.0 release was "Mother's Day," and "Rembrandt" followed "Picasso," and "Colgate" followed it. (For the record, the best release name was a Fedora release, dubbed "Zod." Allowing many fun headlines playing off the Superman II villain.)

Linspire 8.5 Linux Operating System Released, Based on Ubuntu 18.04.3 LTS

Filed under
Linux
Ubuntu

Linspire 8.5 "Swordfish 2" is a major release compared to the previous versions, bringing numerous updated components and various new features for a full-fledged Linux desktop experience. Just like its little brother Freespire 5.0, Linspire 8.5 is based on Ubuntu 18.04.3 LTS (Bionic Beaver) and uses the Linux 5.0 kernel.

Similar to Freespire 5.0, the goal for Linspire 8.5 was to address the bloatware complaints from the community and make the distribution slimmer by including only the "best of breed" applications. Of course, this means that, if users want to replace the default apps or install more, they can use the software center utility.

  • An open source desk to showcase your projects, complete with swappable panels | Arduino Blog

    Almost every maker has run into the problem of not being able to find a convenient display or power source for their project prototype, and thus leading to minor delays and some frustration. However, YouTuber Another Maker has come up with an open source desk concept that makes finding these things simple. The system he built uses a large grid of swappable panels that can simply slide into place within a wooden frame. Behind these are a few devices for both power and connectivity, such as power strips, an Ethernet switch (with PoE capabilities), and an HDMI switch for changing between a Raspberry Pi and a PC.

Kernel: Linux Work by Intel. Oracle, and AMD

  • Intel Proposes Linux Kernel Driver Allow/Deny Filtering

    As part of their work around Trust Domain Extensions (TDX) support for Linux, Intel engineers are proposing a driver filter option for Linux to be able to set allow or deny lists of driver(s) that can or cannot be loaded by the booted kernel. In order to reduce the attack surface within guest virtual machines while still wanting to be able to use the same kernel build between a host and guest, Intel engineers are looking to add this driver filter support to the kernel. When booting the guest, via the kernel command-line they can just specify the specific drivers to allow to be loaded by the kernel or alternatively setting a list of specific drivers that shouldn't be allowed to be loaded by the system.

  • Oracle Working On BPF CO-RE Support For GCC To Easily Run BPF Programs On Any Kernel

  • AMD PTDMA Driver Revised Ahead Of Its Possible Inclusion For Linux 5.15 - Phoronix

    One of the AMD patch series that has been in the works for more than one year is the PTDMA driver providing pass-through DMA engine support on Linux. The driver is now up to its eleventh revision but the mainlining might happen soon. The AMD PTDMA Linux driver effort dates back to September 2019 for enabling their PTDMA controller in performing high bandwidth memory-to-memory and I/O copy operations. Modern AMD CPUs support multiple PTDMA controllers, the PTDMA driver hooks into the kernel's direct memory access (DMA) subsystem and is intended to be used with AMD Non-Transparent Bridge (NTB) devices but not for general purpose peripheral DMA.

    Sudo also called “superuser do” is a command in Linux that allows you to run high-privilege admin commands as a root user. It asked to enter your personal password and confirms your requests by checking a sudoers file. After a fresh Debian 10 installation, you could not execute the privileges tasks by running the sudo command. You will get the error ‘sudo command not found in Debian 10′. The reason for this error is the sudo command isn’t included in Debian 10 by default. In this post, we will show you how to fix sudo command not found in Debian 10 VPS.

Even though you do have a few different options in this regard, Snapdrop is the most effective file-sharing service of the lot.

  • What to do when your Chromebook is no longer supported

    Recently, my Chromebook Pixel 2015 found itself no longer supported. I really loved that Chromebook. The two of us wrote several novels together and the keyboard/screen was unmatched. To this day I've yet to experience a better keyboard/trackpad combo. But, as they say, all things must end. So, when I received the notification that my Chromebook Pixel would no longer be receiving updates, I felt a tinge of sadness. Sure, I had a Pixelbook as a backup device, but it just wasn't the same. It had a nice keyboard, but it was nowhere near that of the Pixel. And the screen? There was zero comparison. I had a choice: Continue using the Pixel, even though it would no longer be receiving upgrades, or do something about it.
