  • Fedora 34 Reviewed: A Great GNOME distro that's worth checking out!

    I had a chance to check out Fedora 34 recently, and was impressed by the overall quality of the GNOME desktop and its implementation. There are a few rough edges, but overall, it's a great distribution. In this video, I talk about the highlights and what makes it stand out.

  • Fedora Linux 34 available for download

    Woo-hoo! Today is officially the day many of us have been waiting for. Yes, Fedora Linux 34 is finally available for download. For many Linux users, Fedora is considered the best overall operating system to be based on that open source kernel. The distro focuses on truly free and open source software -- a pure Linux experience. It is also fairly bleeding edge, but at the same time, it remains stable for everyday use.

    What makes Fedora 34 so exciting? Well, this version of the Linux-based operating system uses GNOME 40 as its default desktop environment, and version 40 is the most electrifying version of GNOME in years. GNOME 40 is notable for a horizontal workspace switcher and having the Dash (favorites launcher) moved to the bottom of the screen. Despite being released last week, Ubuntu 21.04 fails to comes with this version of GNOME.

  • Red Hat boss on Linus Torvalds: 'He's changed the world' | ZDNet

    Red Hat CEO Paul Cormier has continued his regional virtual tour this week, sharing with media in the Asia Pacific region on Thursday his thoughts on what the work Linus Torvalds has done over the last 30 years means for the world.

    "Oh, my gosh, where do you start?," he began.

    "I mean, he's changed the world. Just his vision of an open operating system."

    It's not just the operating system that came out of it, Cormier said.

    "That was the very beginning. Even when we got started with Linux 20-plus years ago, it really wasn't -- it was for hobbyists, but what Linus did was really show the world that open was a better way to develop new innovation," the CEO said. "And I think where Red Hat took it from there, from an enterprise perspective, we showed the world that we really could run critical enterprise workloads on open source-developed software."

    Allwinner D1s (aka F133) is a cost-down version of Allwinner D1 RISC-V processor introduced earlier this year together with a Linux capable development board, with the main difference being the integrated 64MB DDR2. Besides the built-in RAM, Allwinner D1s comes with many of the same features as D1 RISC-V SoC, but loses HDMI output and the HiFi 4 audio DSP, and Allwinner made some tweaks to the IOs with one less I2S audio interface, and general-purpose ADC.

  • Smart Power 3 - A $45 smart power analysis tool for embedded systems developers - CNX Software

    Hardkernel has launched a number of popular Arm SBC’s with the ODROID family over the years, but the Smart Power 3 is a different type of product, as the ESP32-based smart power meter can help embedded systems engineers optimize their hardware and software power consumption and/or check for spurious power peaks during boot up or shutdowns. In the past, we’ve reviewed relatively expansive tools like Qoitech Otii Arc or gone the DIY route, but at $45, Hardkernel offers a power monitoring solution that’s both inexpensive and easy to use, albeit with fewer features than Qoitech’s device.

Reintroducing: Fairphone’s Reuse & Recycle Program

We have relaunched our Reuse and Recycle Program. There are a lot of resources in your old smartphones and we want to make sure we make the most out of them, all the while keeping the environmental impact low and your benefits high. While the old program allowed people to send in their old phones to be reused or recycled, the new program will offer incentives to our community, such as a true market value for their products based on make, model and condition. There’s more to it, of course, but we can’t give away everything in the first paragraph. So read on to learn more about our new and improved Reuse and Recycle Program. The issues We have talked about electronic waste being one of the fastest-growing waste streams on the planet – in 2019 a striking 53.6 Mt of e-waste was created with European citizens contributing around 16kg per person. Globally only 17% of electronic waste (or e-waste) is documented to be collected for recycling, leaving roughly 83% of e-waste undocumented and ending up in shoe boxes or landfills – materials worth around USD 56 billion get lost every year. Additionally, it is estimated that 7-20% of e-waste is set up to be illegally exported, ending up in countries with limited resources and recycling infrastructure – often developing countries – causing enormous health and environmental problems.

Apache Foundation Moves From Mirrors to a CDN to Distribute Software

About a week ago the Apache Software Foundation, home of the Apache Web Server, Hadoop, OpenOffice, and over 350 other open source software projects, announced the end of the line for its system of mirror sites for delivering its software to users, From now on, the foundation will be using a content delivery network instead. Most users of open source software, especially those who have downloaded Linux distributions, will be familiar with download mirroring sites, usually just called “mirrors,” which rose to prominence in the 1990s as the internet became the preferred way to distribute software.

  • How to Install Nvidia 495.xx Beta Drivers on Linux Mint 20 - LinuxCapable

    Most modern Linux Desktop systems such as Linux Mint come with an Nvidia driver pre-installed in the Nouveau open-source graphics device driver for Nvidia video cards. For the most part, this is acceptable; however, if you are using your Linux system for graphical design or gaming, you may get better drivers. Historically, the Nouveau proprietary drivers are slower than Nvidia’s proprietary drivers, along with lacking the newest features, software technology, and support for the latest graphics card hardware. In most situations, upgrading your Nvidia Drivers using the following guide is more beneficial than not doing it. In some cases, you may see some substantial improvements overall. The following tutorial will teach you how to install the latest bleeding-edge Nvidia Beta Graphic drivers for Linux Mint 20.

  • How To Setup NTP Server and Client on Ubuntu 20.04 LTS - idroot

    In this tutorial, we will show you how to install a setup NTP server and client on Ubuntu 20.04 LTS. For those of you who didn’t know, NTP (stands for network time protocol) is used to synchronize the system clock of the client system with the clock of the server. The NTP server has features that allow synchronization between two systems with an accuracy of one nanosecond so that the two systems can communicate easily. System time applies not only to the user but also to the computer itself. In fact, time stamps make it easy to communicate between two or more computers and provide network services properly, as well as optimizing the network card. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the configure NTP server and client on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.
