  • 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.

  • GStreamer & automated testing in Lyon

    Following three days at Embedded Linux Conference Europe, Collaborans are continuing their stay in the capital of France’s Auvergne-Rhône-Alpes region to take part the annual GStreamer Conference, as well as the Automated Testing Summit.

    Our entire multimedia team will be attending the GStreamer Conference, which takes place at L'Embarcadère on October 31 & November 1. They'll be presenting no less than a dozen times during the conference, on topics including RTP jitter buffer timers, network streaming protocols and PipeWire in the automotive industry. Read below for details & links to each of their talks.

    Back at the Palais des congrès de Lyon where ELCE took place, Gustavo Padovan, Linux Core Technologies Lead, will be taking part in the Automated Testing Summit on October 31. KernelCI will undoubtedly be a hot topic and heavily discussed as it became a Linux Foundation project just a few days ago.

  • 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.

Linuxfx 11.1 WxDesktop 11.0.3

It is with great pleasure that we announce the release of Linuxfx version 11.1.1103. This update releases several new features for the operating system. The system kernel has been updated to version 5.13, bringing better support for more modern hardware. System tools gained new translations: French, German, Italian, Japanese, Chinese, Spanish, American and Portuguese is now supported for WxDesktop. Android support has been improved, now in addition to supporting opengl, we also release support for Vulkan (experimental). Finally, all system packages have been updated, including WxDesktop, Onlyoffice and many others. The image has been scaled down to fit on a DVD. Users of older versions will receive this update over the internet. New users can download the new image from our portal. Read more

Kernel: LWN Articles and F2FS in Linux 5.17

  • VSTATUS, with or without SIGINFO [LWN.net]

    The Unix signal interface is complex and hard to work with; some developers have argued that its design is "unfixable". So when Walt Drummond proposed increasing the number of signals that Linux systems could manage, eyebrows could be observed at increased altitude across the Internet. The proposed increase seems unlikely to happen, but the underlying goal — to support a decades-old feature from other operating systems — may yet become a reality. The kernel is able to support up to 64 different signal types, which seems like a fair number, but all 64 are taken, on some architectures at least. That makes it impossible to add new signal types to Linux. Drummond sought to address that problem by raising the limit to 1024, which would surely be enough for all time. Raising the limit requires making some subtle changes to the user-space API (putting a larger signal mask into the information passed to realtime signal handlers, for example) that have the possibility of breaking applications, which means that extra scrutiny would be required. But that, it seems, is what would be needed to be able to add more signals.

  • Fixing a corner case in asymmetric CPU packing [LWN.net]

    Linux supports processor architectures where CPUs in the same system might have different processing capacities; for example, the Arm big.LITTLE systems combine fast, power-hungry CPUs with slower, more efficient ones. Linux has also run for years on simultaneous multithreading (SMT) architectures, where one CPU executes multiple independent execution threads and is seen as if it were multiple cores. There are architectures that mix both approaches. A recent discussion on a patch set submitted by Ricardo Neri shows that, on these systems, the scheduler might distribute tasks in an inefficient way.

  • Some 5.16 kernel development statistics

    The 5.16 kernel was released on January 9, as expected. This development cycle incorporated 14,190 changesets from 1,988 developers; it was thus quite a bit busier than its predecessor, and fairly typical for recent kernel releases in general. A new release means that the time has come to have a look at where those changes came from. The 1,998 developers contributing to 5.16 was the second-highest number ever, with only 5.13 (with 2,062 developers) being higher. This time around, 296 developers contributed their first change to the kernel, which is at the high end of the typical range.

  • F2FS With Linux 5.17 Makes Some Performance Improvements - Phoronix

    F2FS as the Flash-Friendly File-System may not see too much use out of desktop Linux distributions at least as it concerns any easy/semi-endorsed root install option, but this file-system does continue maturing and seeing much use by enthusiasts and especially among the plethora of Android devices now supporting this flash-optimized file-system. With Linux 5.17, F2FS has some performance improvements and other fixes. F2FS lead developer and maintainer Jaegeuk Kim sent in the Flash-Friendly File-System updates on Tuesday. This cycle there is work for addressing performance issues in the checkpoint and direct I/O code. There is also improvements to the page cache management code used as part of the file-system compression support.
