  • Seeed Unveils Its First Raspberry Pi-Powered Human-Machine Interface Device

    Seeed Technology, the hardware incubation platform that has enabled over 350,000 developers to realize products and build applications, today unveils their first Raspberry Pi-powered industrial human-machine interface (HMI) device, reTerminal. Aiming at bringing the next generation of HMI, reTerminal is fully-featured, designed, and certified for IoT developers to build industrial applications based around the Raspberry Pi® Compute Module 4 (CM4), ready to deploy to unlock endless scenarios at the edge.

  • Raspberry Pi 4 Model B Review: Can It Really Replace Your PC?

    Arthur C. Clarke, in the year 1974, said, “One day, a computer will fit on a desk.” We’ve come a long way since “fittable” computers like PCs and Laptops/Notebooks first came into the picture, haven’t we? Who would’ve further predicted that in the future, we’d have pocket-sized computers that can fit in our hands like our smartphones and Raspberry Pis?

  • Quartz64 Model B SBC revealed, Model A gets hit by production delays - CNX Software

    Pine64 unveiled the Quartz64 SBC powered by Rockchip RK3566 processor a few months ago. More specifically they provided details about Quartz64 Model A at the time, a featured-rich variant with SATA, PCIe, multiple display outputs, etc… During the announcement, Pine64 also indicated a Raspberry Pi-sized Quartz Model B was in the works but did not have a prototype to showcase just yet. In the latest Pine64 April update, the community showcased the new board, reported software progress, and information about production delays for Model A.

Free and Open-Source Software (FOSS) - Everything You Need to Know

One thing is sure; FOSS has taken significant strides over the way since the 80s. Apparently, FOSS has been around since the 1950s, when purchased hardware was run by free specialized bundled software. Until 1985, Richard Stallman founded the Free Software Foundation that was meant to support the Free Software Movement. FSF committed to Free Software, the one that users could use for free, modify, sturdy, and even share. According to Stallman, the main difference between open source and free software is the fact that “open source is ideally a development methodology, while free software is merely a social movement.” A year later, FOSS came into the limelight based on four freedoms. The four freedoms of free software were established solely as a result of the free software movement, and they denote what exactly constitutes free software. Here are the freedoms; Freedom 0 – this is the freedom that allows you to use the program for any purpose; you simply run it as you wish. Freedom 1 – it is the freedom to accessing the code. It means that you can study how the program works. Interestingly, you have the freedom to change it to do your computing just as you wish. Freedom 2 – this is the freedom to redistribute the copies to others to help them. Freedom 3 – it’s the freedom to distribute your copies of modified versions to others. That way, you give the entire community the chance to benefit from the changes you made. A precondition for this is accessing the source code. Read more

IBM/Red Hat Leftovers

  • IBM COBOL for Linux on x86 1.1 brings COBOL capabilities to Linux

    As I understand it, there’s still a lot of COBOL code all over the industry, so it makes sense for IBM to make its COBOL technologies available to more people.

  • Red Hat and NEC Corporation Collaborate to Drive Kubernetes-based 5G Adoption

    Red Hat, Inc., the world's leading provider of open source solutions, today announced a collaboration with NEC Corporation to deliver 5G solutions built on Red Hat OpenShift, the industry’s leading enterprise Kubernetes platform. With NEC’s 5G core network solutions running on Red Hat OpenShift, organizations will be able to capitalize on 5G across a broad set of use cases including 5G core, 5G radio access networks (RANs), edge computing, artificial intelligence, machine learning and more, helping them create new revenue opportunities. 

  • Red Hat Launches Red Hat Learning Subscription Premium

    Red Hat, Inc., the world's leading provider of open source solutions, today announced the availability of Red Hat Learning Subscription Premium. This new offering, available in North America initially, provides access to self-paced learning experience and access to instructors via live, interactive, virtual classes. Courses cover topics from across Red Hat’s product portfolio and are designed to help individuals and teams keep pace with the evolving technology landscape. This offering will roll out globally in the future. 

  • Coding: an opportunity for everyone

    While Covid has hit many industries hard, increasing unemployment numbers and job uncertainty, the demand for technical skills is greater than ever. According to FT analysis nearly 800,000 additional jobs were created in computer programming and related services. Red Hat launched new research, which found that one in 20 (5%) of more than 30,000 respondents across Europe have chosen to take up coding as a new skill since the pandemic. Two thirds of them (65%) said their motivation was to reskill for a new job or career.

Kernel: Rust and Linux 5.14, Least Recently Used (LRU), Linux 5.12 Says Away

  • Rust support in Linux may be possible by 5.14 release: Torvalds

    The first patches for Rust support in the Linux kernel have been posted and the man behind the kernel says the fact that these are being discussed is much more important than a long post by Google about the language. Linus Torvalds told iTWire in response to queries that Rust support was "not there yet", adding that things were "getting to the point where maybe it might be mergeable for 5.14 or something like that".

  • Google Is Working On A New And Possibly Better LRU Memory Management Framework For The Linux Kernel

    The linux kernel loves to fill all available RAM with caches of files and other items. This speeds things up because memory caches are much faster than Direct I/O. One obvious bi-effect is that all system RAM can be in use and, at the same time, be free as in available for applications who may need it. The Linux kernels Least Recently Used (LRU) framework decides what gets kept and what gets thrown out in case some system memory is needed by an applications. It covers the majority of a machines memory pages. Slab caches and a few other caches are exceptions. LRU pages are put in one of two linked lists with active or inactive pages. Pages taken from the end of the inactive list are freed unless it has the reference bit set. Pages are, in that case, moved to the beginning of the active page list and the reference bit is cleared. Dirty pages, as in pages that should be written to disk, are put in the writeback queue and later moved to the beginning of the inactive memory list. Memory pages that are unreferenced and clean get reused.

  • The 12 Most Interesting Changes Of Linux 5.12 - PS5, N64, Intel VRR, RDNA2 OverDrive

    If all goes well the Linux 5.12 stable kernel will be released this weekend. It's been a fairly calm week so far in Linux 5.12 Git land but if things tick up Linus Torvalds may defer the stable release by one week to allow for an eighth and final release candidate. In any case, Linux 5.12 is packing a lot of exciting changes. After the Linux 5.12 merge window I wrote a Linux 5.12 feature overview. But for those that didn't see it or recall it from two months ago, here is a look at the top twelve features/changes coming with Linux 5.12 for a quick recap
