  • Open-source Felfil Evo 3D printing filament extruder available from $369

    Italian 3D printing company Felfil has made available its Felfil Evo filament extruder, initially the subject of a Kickstarter back in 2015. The extruder is available in basic (€299, $369), complete (€599, $738), and assembled (€719, $886) versions.

  • Michigan Tech engineers develop open-source GMAW metal 3D printer for only $1,200

    Joshua Pearce, a prolific engineer at Michigan Tech, has been working on developing an affordable metal 3D printing technology. The project involves hacking a CNC router kit and an metal inert gas (MIG) welder to create a low-cost GMAW metal 3D printer.

  • 3D Printed, Open Source Glia Stethoscope Receives Clinical Validation

    Dr. Tarek Loubani spent some time working in hospitals in the Gaza Strip during the worst of the chaos and violence that is unfortunately still going on there. Due to a long-standing blockade, medical supplies were scarce in the region – so scarce that doctors could often not find a stethoscope when they needed one. So Dr. Loubani came up with his own solution – he 3D printed a stethoscope, for about 30 cents.

Linux-powered wireless gateway supplies four surge-protected serial ports

Artila’s compact “IoT Gateway Matrix-704” runs Linux on a Microchip SAMA5D35 and provides GbE and Fast Ethernet, mini-PCIe and micro-SIM slots, a USB port, and 4x isolated, surge protected RS-485 ports. Artila has introduced several of its Matrix IoT gateways with isolated serial ports, including the Matrix-710 and Matrix-713. Its new Matrix-704 can have its 4x RS-485 ports configured with optional isolation and it also comes standard with surge protection. The Matrix-704 has the same 536MHz, Cortex-A5 Microchip ATSAMA5D35 SoC as the more feature rich Matrix-710 and Matrix-713, as well as the recent Matrix-702, which lacks serial ports. Read more

  • Linux Getting Fixed Up For Handling Pointing Sticks On Some Touchpads

    For input devices on some laptops that are a combination of a pointing stick and touchpad, the Linux kernel's multi-touch driver will finally begin handling them correctly. At least for Synaptics and Elan devices that offer a combination of a pointing stick and touchpad, the Linux kernel has been ignoring the input events from the pointing stick. But with Linux 5.8 that will change in properly handling the combo multi-touch devices via the hid-multitouch driver and this change is set to be back-ported as well to the various Linux kernel stable series being supported.

  • Mesa 20.1 Features Include Big Improvements For Open-Source Intel, Radeon Graphics Drivers

    The release of Mesa 20.1 is imminent as the latest quarterly feature update to this collection of open-source OpenGL/Vulkan drivers predominantly in use by Linux systems. Here is a look at the many exciting improvements with Mesa 20.1.

  • Hybrid cloud and multi-cloud: what is the difference?

    Hybrid cloud and multi-cloud are two exclusive terms that are often confused. While the hybrid cloud represents a model for extending private cloud infrastructure with one of the existing public clouds, a multi-cloud refers to an environment where multiple clouds are used at the same time, regardless of their type. Thus, while the hybrid cloud represents a very specific use case, multi-cloud is a more generic term and usually better reflects reality. Although both architectures are relatively simple to implement from the infrastructure point of view, the more important question is about workloads orchestration in such environments. In the following blog, I describe the differences between hybrid clouds and the multi-cloud and discuss the advantages of orchestrating workloads in a multi-cloud environment with Juju. [...] In turn, multi-cloud simply refers to using multiple clouds at the same time, regardless of their type. There is no dedicated infrastructure that facilitates it. There is no dedicated link, single IdM system, unified LMA stack or an integrated network. Just instead of a single cloud, an organisation uses at least two clouds at the same time. The goal behind the multi-cloud approach is to reduce the risk of relying on a single cloud service provider. Workloads can be distributed across multiple clouds which improves independence and helps to avoid ‘vendor lock-in’. Furthermore, as the multi-cloud is usually a geographically-distributed environment, this helps to improve high availability of applications and their resiliency against failures. Finally, the multi-cloud approach combines the best advantages of various cloud platforms. For example, running databases on virtual machines (VMs) while hosting frontend applications inside of containers. Thus, workload orchestration remains the most prominent challenge in this case.

  • Kubernetes for Data Science: meet Kubeflow

    Data science has exploded as a practice in the past decade and has become an undisputed driver of innovation. The forcing factors behind the rising interest in Machine Learning, a not so new concept, have consolidated and created an unparalleled capacity for Deep Learning, a subset of Artificial Neural Networks with many hidden layers, to thrive in the years to come.
