Filed under
Linux

I’m really starting to appreciate the benifits of dual factor authentication across the board, so this Howtoforge article is of interest to anyone who wants to secure SSH access on thier Linux systems. I previously posted about using your mobile phone as the something you have bit, well this is another method.

GNU/Linux Laptops/Desktop: Librem 14, System76 and More

  • Librem 14 Enhancements

    The Hardware kill switches have seen a number of enhancements. This is also the first Purism laptop to ship with a BIOS write protection switch and all M.2 key-E interfaces implemented. The Librem 14 is our most powerful and most secure laptop yet. If you want full control over your computer with cutting-edge, powerful hardware, the Librem 14 is the best (some would say the only) choice. Make it yours here.

SUSE: OBS, 'Cloud' and Chat With Linux Kernel Developer at SUSE

  • OBS NDI™ Plugin on openSUSE

    The NDI plugin offers a fairly easy way to send OBS video signal (presumably other applications can take advantage of this too) to another OBS instance on another machine. This can come in handy for numerous reasons such as splitting up workloads between machines by capturing output from one machine, such as gaming computer, to stream with a dedicated unit that interfaces with YouTube. This has advantages in that you can move the machine doing the heavy lifting into another room or across the room as to not hear the fans and so forth. In my case, my primary machine is getting long in the tooth. I prefer the setup I have as far as the screen layout and height of the computer as well as the location. I use my AMD Desktop / server / workstation machine to talk to YouTube or Twitch directly with that OBS instance and record locally in effect freeing up my laptop from quite a bit of the workload.

  • Women in Tech: “Aptitude has nothing to do with gender or inborn capabilities”

    Women are underrepresented in the tech sector —myth or reality? Three years ago, we launched a diversity series aimed at bringing the most inspirational and powerful women in the tech scene to your attention. Today, we’d like you to meet Jessica Yu, Linux Kernel Developer at SUSE. A research study by The National Center for Women & Information Technology showed that “gender diversity has specific benefits in technology settings,” which could explain why tech companies have started to invest in initiatives that aim to boost the number of female applicants, recruit them in a more effective way, retain them for longer, and give them the opportunity to advance. But is it enough? Three years ago, we launched a diversity series aimed at bringing the most inspirational and powerful women in the tech scene to your attention.

RHEL/CentOS 8.2 also isn't officially supported but jut 8.1.

  • Lockdep False Positives, some stories about

    Recently we’ve looked a bit at lockdep annotations in the GPU subsystems, and I figured it’s a good opportunity to explain how this all works, and what the tradeoffs are. Creating working locking hierarchies for the kernel isn’t easy, making sure the kernel’s locking validator lockdep is happy and reviewers don’t have their brains explode even more so.

  • AWOW AK41 Mini Desktop PC – Web Browsing – Week 6

    This is a weekly blog chronicling my experiences of using the AWOW AK41 Mini Desktop PC on Linux. This week’s blog focuses on a fundamental desktop activity. Surfing the web. A web browser is the quintessential desktop application. Everyone needs one, and there is not a desktop Linux distribution around that does not make a web browser available. In 2020, it’s estimated 4.8 billion people used a web browser. For Linux, there’s a web browser for every need. There’s heavyweight browsers jammed with a large feature set with addons and extensions. Then there’s leaner web browsers which still offer an attractive graphical interface. And there’s lightweight browsers including console based web browsers too. Over the years, I’ve tried almost every web browser available for Linux. For the AWOW AK41, my focus has rested primarily with Chrome and Firefox. I’ve used them extensively on the AK41 for the past 6 weeks browsing hundreds of web sites that are laden to the hilt with JavaScript. I’ve also written and edited numerous articles for LinuxLinks (including this series on the AK41), internet shopping, played (too many) web based games, substituted my regular email client (Thunderbird) with Gmail, watched videos on YouTube, iPlayer and other services. How does the AK41 perform?

  • Mini-PC and SBC build on Whiskey Lake

Supermicro has launched a fanless, 8th Gen Whiskey Lake SBC and mini-PC. The SYS-E100-9W-H mini-PC (or SuperServer E100-9W-H), which was reported on by Fanless Tech, is certified only to run Windows 10, but the 3.5-inch X11SWN-H-WOHS SBC supports Ubuntu. Applications include industrial automation, retail, smart medical expert systems, kiosks, interactive info systems, and digital signage.

  • MeLE PCG02 GLK Fanless PC Stick Comes with 10W Celeron J4105 Processor, Gigabit Ethernet

    Back in 2018, MeLE unveiled PCG02 Apo TV stick with a 6W Intel Celeron N3450 quad-core Apollo Lake processor, 4GB RAM, 32GB storage, HDMI output, USB 3.0 ports, and an unusual Gigabit Ethernet port for this form factor. The company is back with an upgraded model as MeLE PCG02 GLK PC stick is based on the same design but with a more powerful Intel Celeron J4105 Gemini Lake processor with a 10W TDP. The design is fanless, so it will be interesting to find out how well they handle cooling.

  • Whiskey Lake computer has PoE and optional PCIe x4 AI accelerators

    IEI’s rugged, Linux-ready “DRPC-230-ULT5” DIN-rail system runs on 8th Gen U-series CPUs with 3x GbE, up to 6x USB 3.2 Gen 2, 6x COM, SATA, DP, HDMI, mini-PCIe, M.2, and optional PCIe x4 with Myriad X-based AI cards.

  • Getting to know RISC-V through the hifive1-revb board

    I have been interested in the RISC-V architecture for a while. RISC-V is an Instruction Set Architecture, like ARM, MIPS or x86, but it is developed and provided under an open source license. A couple of weeks ago the hifive1-revb development board I ordered from Crowd Supply arrived and I have been using it to get to know RISC-V a bit. The small get-to-know-the-board project I settled on was to use the LEDs on the board to blink HELLO in morse code using RISC-V assembly.
