  • RISC-V gains momentum as it moves from MCUs to Linux-friendly SoCs

    The open source RISC-V ISA has evolved quickly into silicon, thanks to help from companies like SiFive and Microsemi. SiFive’s HiFive Unleashed board should arrive less than two years after SiFive announced its first Linux-driven Freedom SoCs.

    It’s been two years since the open source RISC-V architecture emerged from computer labs at UC Berkeley and elsewhere and began appearing in soft-core implementations designed for FPGAs, and over a year since the first commercial silicon arrived. So far, the focus has primarily been on MCU-like processors, but last October, SiFive announced the first Linux-driven RISC-V SoC with its quad-core, 64-bit bit Freedom U540 (AKA U54-MC Coreplex). A few days ago at FOSDEM, SiFive opened pre-sales for an open source HiFive Unleashed SBC that showcases the U540.

  • SiFive releases Linux SoC processor and board

    SiFive Inc. (San Mateo, Calif.), a startup that is offering processor cores that comply with the RISC-V open source architecture, has launched a Linux-capable RISC-V based processor chip, the Freedom U540 SoC.

  • Chip Embarks As First Linux-Capable RISC-V Based SoC

    SiFive launches what it calls the industry's first Linux-capable RISC-V based processor SoC. The company recently demonstrated the first real-world use of the HiFive Unleashed board featuring the Freedom U540 SoC, based on its U54-MC Core IP. During the demo, SiFive provided updates on the RISC-V Linux effort, surprising attendees with an announcement that the presentation had been run on the HiFive Unleashed development board. With the availability of the HiFive Unleashed board and Freedom U540 SoC, SiFive has brought to market the first multicore RISC-V chip designed for commercialization, and now offers the industry's widest array of RISC-V based Core IP.

  • PIXO Pixel - Open Source LED Display for Makers

    Sean Hodgins is an inventor and maker interested in purposing current technologies in new and different ways. He’s currently running a crowdfunding campaign on Kickstarter for the PIXO Pixel, an open source RGB display that controls 256 LEDs.

  • AFRL, NextFlex leverage open-source community to create flexible circuit system

    Lightweight, low-cost and flexible electronic systems are the key to next-generation smart technologies for military as well as consumer and commercial applications.

    An Air Force Research Laboratory-led project in conjunction with NextFlex, America’s Flexible Hybrid Electronics Institute, has resulted in the first ever, functional samples of flexible Arduino circuit board systems made by using a flexible hybrid electronics manufacturing process, setting the stage for smart technologies for the internet of things and sensor applications like wearable devices.

Server: HTTP Clients, IIS DDoS and 'DevOps' Hype From Red Hat

  • What are good command line HTTP clients?
    The whole is greater than the sum of its parts is a very famous quote from Aristotle, a Greek philosopher and scientist. This quote is particularly pertinent to Linux. In my view, one of Linux’s biggest strengths is its synergy. The usefulness of Linux doesn’t derive only from the huge raft of open source (command line) utilities. Instead, it’s the synergy generated by using them together, sometimes in conjunction with larger applications. The Unix philosophy spawned a “software tools” movement which focused on developing concise, basic, clear, modular and extensible code that can be used for other projects. This philosophy remains an important element for many Linux projects. Good open source developers writing utilities seek to make sure the utility does its job as well as possible, and work well with other utilities. The goal is that users have a handful of tools, each of which seeks to excel at one thing. Some utilities work well independently. This article looks at 4 open source command line HTTP clients. These clients let you download files over the internet from the command line. But they can also be used for many more interesting purposes such as testing, debugging and interacting with HTTP servers and web applications. Working with HTTP from the command-line is a worthwhile skill for HTTP architects and API designers. If you need to play around with an API, HTTPie and curl will be invaluable.
  • Microsoft publishes security alert on IIS bug that causes 100% CPU usage spikes
    The Microsoft Security Response Center published yesterday a security advisory about a denial of service (DOS) issue impacting IIS (Internet Information Services), Microsoft's web server technology.
  • 5 things to master to be a DevOps engineer
    There's an increasing global demand for DevOps professionals, IT pros who are skilled in software development and operations. In fact, the Linux Foundation's Open Source Jobs Report ranked DevOps as the most in-demand skill, and DevOps career opportunities are thriving worldwide. The main focus of DevOps is bridging the gap between development and operations teams by reducing painful handoffs and increasing collaboration. This is not accomplished by making developers work on operations tasks nor by making system administrators work on development tasks. Instead, both of these roles are replaced by a single role, DevOps, that works on tasks within a cooperative team. As Dave Zwieback wrote in DevOps Hiring, "organizations that have embraced DevOps need people who would naturally resist organization silos."

Purism's Privacy and Security-Focused Librem 5 Linux Phone to Arrive in Q3 2019

Initially planned to ship in early 2019, the revolutionary Librem 5 mobile phone was delayed for April 2019, but now it suffered just one more delay due to the CPU choices the development team had to make to deliver a stable and reliable device that won't heat up or discharge too quickly. Purism had to choose between the i.MX8M Quad or the i.MX8M Mini processors for their Librem 5 Linux-powered smartphone, but after many trials and errors they decided to go with the i.MX8M Quad CPU as manufacturer NXP recently released a new software stack solving all previous power consumption and heating issues.

Hack Week - Browsersync integration for Online

Recently my LibreOffice work is mostly focused on the Online. It's nice to see how it is growing with new features and has better UI. But when I was working on improving toolbars (eg. folding menubar or reorganization of items) I noticed one annoying thing from the developer perspective. After every small change, I had to restart the server to provide updated content for the browser. It takes few seconds for switching windows, killing old server then running new one which requires some tests to be passed. Last week during the Hack Week funded by Collabora Productivity I was able to work on my own projects. It was a good opportunity for me to try to improve the process mentioned above. I've heard previously about browsersync so I decided to try it out. It is a tool which can automatically reload used .css and .js files in all browser sessions after change detection. To make it work browsersync can start proxy server watching files on the original server and sending events to the browser clients if needed. Read more
