  • Arduino Nano Floppy Emulator For When Your Disk Is Not Accessible | Hackaday

    Among the plethora of obsolete removable media there are some which are lamented, but it can be difficult to find those who regret the passing of the floppy disk. These flexible magnetic disks in hard plastic covers were a staple of computing until some time in the early 2000s, and their drives could be found by the crateload in any spares box. But what about today, when there’s a need for a real floppy drive and none is to be found? Enter [Acemi Elektronikci], with an Arduino Nano based floppy emulator, that plugs into the floppy port of a PC old enough to have one, and allows the easy use of virtual floppy disks.

  • HarmonyOS development board shows up for $11

    Last year, we noted the Hisilicon Hi3861 based HiSpark WiFi IoT development board with supports LiteOS and HarmonyOS that was available in China for just under $10, or as part of a devkit with baseboard and modules for around $60. Although not very practical, buying from Taobao was possible, but there’s now what appears to be a new revision of the Hi3861V100 based HarmonyOS development board in a wider form factor on Banggood for $10.99.

  • Raspberry Pi CM4 handheld console looks like a Nintendo Switch Lite - CNX Software

    StonedEge and Dmcke5 have come up with an incredibly well-designed Raspberry Pi CM4 handheld console that looks like a Nintendo Switch Lite “clone”, and that can run Dreamcast and PSP emulators at full speed using RetroPie. The RetroLite CM4 The design includes a 5-inch display, speakers, all buttons, joysticks, and D-PAD controlled via a custom Arduino board, a micro HDMI port to connect an external display, and a 4000 mAh LiPo battery charged over the USB Type-C port, and it seems to work, albeit we are told there’s still some more work to do.

  • “Industrial Pi” Use Cases with Ubuntu and AMD

    DFI’s GHF51 mini industrial-grade motherboard, and the EC90A-GH mini fanless industrial computer, are the world’s first industrial computer products that have passed the Ubuntu IoT hardware certification and are equipped with high-performance AMD processors. The 1.8-inch motherboard of the Ryzen R1000 processor has the same small size as the Raspberry Pi but brings unprecedented powerful computing performance, powerful expansion capabilities, and durability tailored for industrial applications. Combining the online update mechanism of the Ubuntu Certified Hardware and the online application store, the breakthrough development of “Industrial Pi” will redefine the future of the Industrial Internet of Things.

  • WP Briefing: Episode 18: The Economics of WordPress

    In episode 18 of WP Briefing, Josepha Haden Chomphosy reflects on a recent lecture that she gave to students at Hendrix College in which she explored the economics of WordPress and the principles that sustain the project’s ecosystem.

  • Linux Action News 211

    We cover what's special about Plasma's 25th-anniversary edition, chat with CloudLinux's CEO, and detail why Apple supporting Blender is good for all of us.

  • These Open Source SCAMMERS are getting out of control! - Invidious

    No, Inkscape isn't a scam. In fact, it's the best vector illustration tool on the planet. But, much like Krita just a few weeks ago, scammers have registered official-looking domains that are meant to trick people into downloading and installing ransomware. It's sad to see and I can't think of many ways we can combat this besides raising awareness.

  • Josh Bressers: Episode 293 – Scoring OpenSSF Security Scoring

    Josh and Kurt talk about the release of OpenSSF Security Scorecards version 3. This is a great project that will probably make a huge difference. Most of the things the scorecards are measuring are no brainier activities. We go through the list of metrics being measured. There are only a few that we don’t think are fantastic.

  • Use and contribute to a new Open Source Cloud Guide

    Today, at All Things Open, IBM is releasing the Open Source Cloud Guide, which highlights various use cases that are important in hybrid cloud environments, features the important open source projects in those areas, and discusses how various clouds are using open source in their offerings. By open sourcing the guide, developers are able to both use and contribute to the learnings and use cases

  • Announcing Cryostat 2.0: JDK Flight Recorder for containers

    Cryostat is a container-native JVM application that provides a secure API for profiling and monitoring containers with JDK Flight Recorder (JFR). JDK Flight Recorder collects profiling and diagnostic data from applications using JFR events stored in binary flight recordings. When requested, Cryostat can retrieve, store, and analyze flight recordings from containerized Java virtual machines (JVMs) to assess overall application health. Users can download recording files and upload them to JDK Mission Control (JMC) or Grafana for further analysis. This article introduces Cryostat and shares new features in the 2.0 release, including example use cases, tips for getting started, and additional release notes. For more information about Cryostat fundamentals, visit Introduction to Cryostat: JDK Flight Recorder for containers.

  • Sensitive information detection using the NVIDIA Morpheus AI framework

    The growth of cloud-native applications has driven an explosion of east-west network traffic within a datacenter where applications can create hundreds of thousands of network connections among virtual machines and containers. As a consequence, the ability to track, monitor, and secure a datacenter in a timely manner has risen above that of any individual or team, thus requiring the help of AI and machine learning (AI/ML) to enable ITOps, infrastructure security, and DevSecOps teams to manage the complexity of modern cloud-native applications and the underlying platforms. Red Hat and NVIDIA have been working together to bring the security analytics capabilities of the NVIDIA Morpheus AI application framework to Red Hat infrastructure platforms for cybersecurity developers. This article provides a set of configuration instructions to Red Hat developers working on applications that use the NVIDIA Morpheus AI application framework and NVIDIA BlueField data processing units (DPUs) to secure interservice communication.

  • DevSecOps: 11 questions to ask about your security strategy now

    It’s the fourth and final quarter of 2021, believe it or not. That makes it time for IT leaders to review and evaluate how things are going – and plan for 2022. Security sometimes gets left out of those conversations. We’re here to make sure that doesn’t happen, with an extensive list of questions worth asking as you assess your security posture and look for ways to improve. We’ll start with a series of topics that are particularly relevant for teams that are considering or already implementing a DevSecOps strategy, then we’ll cover a series of fundamental questions worth asking in any organization – especially those currently struggling to modernize their security approach.

  • How Podman runs on Macs and other container FAQs | Enable Sysadmin

    As the Podman machine function becomes more used—particularly on Macs—there have been many questions about how this all works. Some of what is tossed around on the internet is pure speculation, so this article aims to eliminate any speculation. Many people do not realize that containers are really Linux. As such, Linux containers cannot run natively on macOS. Therefore, the containers must run in a Linux virtual machine (VM), and a Podman client interacts with that VM. This is in line with all solutions for running containers on macOS.
