  • 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

    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.

  • Remove ^M (CTRL-M) Characters from a File in Linux - Putorius

    Operating systems have different ways to handle a newline in their text editors. For example Windows uses a specific carriage return (CR) which is depicted as ^M on Linux, followed by a line feed (LF) to indicate a newline. Linux and UNIX on the other hand use only the line feed to denote the end of a line. This often causes issues when transferring (or even copy and pasting) a file from Windows to Linux. It is hard to spot, and often leaves people scratching their head and wondering why their configuration file is not working.

  • When you need the numbers just right – benchmark and profiling applications in the Snap Store | Ubuntu

    The world of software is a vast and complex one, often too difficult to easily assess by human intuition alone. Which is why detailed and accurate measurements of software behavior are essential in helping us understand and gauge how well our applications perform. The Snap Store has a fair share of productivity tools and utilities, including a wide range of benchmarking and profiling tools. These are designed to help developers, system administrators and hardcore enthusiasts get a precise sense of their software, whether as part of research and design or for troubleshooting ongoing problems in production environments. Let’s have a little tour.

    The Ubuntu Technical Board is responsible for the technical direction of Ubuntu. It makes decisions on package selection, packaging policy, installation systems and processes, kernel, X server, display management, library versions, and dependencies.
