Orbbec's 3D cam dev kit runs Linux on Amlogic A311D
Orbbec has launched a Linux development board for its 3D depth cameras, such as the circa-2015 Astra Pro, which is incorporated on its Linux-based Persee camera computer. The Zora P1 features a high-end, hexa-core Amlogic A311D plus HDMI, GbE with optional PoE, WiFi/BT, MIPI-DSI and -CSI, and 5x USB ports.

SeaMonkey 2.53.5.1 compiled on Raspberry Pi4
Compiling SeaMonkey, now that is a challenge. I tried yesterday, and the 'nss' module failed. It was configured to use the internal 'nss' and 'nspr' and not the system libraries, as the latter were too old. So last night I did a complete recompile in OE, with later versions of 'nspr' and 'nss', and today compiled SM to use these system libraries ...and success.
I do come across posts on forums, people asking how to compile SM on an ARM board, so will post some notes here...
I have compiled with EasyOS 64-bit (armv8-a+crc) running on a Raspberry Pi 4, with 8GB RAM. The source is on a 500GB SSD, plugged in via USB3, and using the standard official Raspberry Pi 3A power supply. The SSD has a 32GB swap partition.
EasyOS for the Pi4 is currently under development and not yet released, but expected to be very soon.

EasyOS using VC4 graphics acceleration on Pi4
Commenting-out that line in 'config.txt' causes Xorg to load the 'fbdev' (frame buffer) driver. This gave quite snappy desktop rendering, however it will fall down when rendering games and video.
The solution was to recompile 'mesa' with the 'vc4_dri.so' driver, which sits at /usr/lib/dri. I mentioned in a previous post that I had recompiled everything in OE for a generic aarch64 target CPU, armv8-a+crc. This compiled mesa without VC4 driver.
However, I had previously compiled in OE for a rpi4 target, and that has the driver. So, have created a PET just with that driver. -
Arduino Blog » Detect problems with your Arduino projects
The Arduino team created a tool to check Arduino projects for common problems. Arduino Lint runs over 175 checks on your sketches, libraries, and boards platforms which cover specification compliance, Library Manager submission requirements, and best practices.
[...]
Arduino Lint would be a great addition to your continuous integration system. Running the tool after each change to the project can allow you to identify any problems that were introduced.

OpenSUSE: YaST Development Sprint and Digest of YaST Development Sprint
| The 10 Best Linux Server Distributions [2021 Edition]One of the best things about Linux is the various types of distributions it has to offer. No matter how you plan to use your Linux PC, there’s a Linux distro optimized with all the necessary tools and functionalities to meet your needs. And this brings us to Linux server distributions – Linux distros optimized to be used on servers. These are lightweight Linux distros, sometimes even stripped of a desktop environment, and packed with tools to improve speed, stability, and security – the traits of a good server OS.
But with that being said, there are literally hundreds of Linux server distros circulating the internet. So which one should you choose for your home server or even for professional use? Well, to answer your question, we have put together a comprehensive list of the 10 best Linux Server Distributions for 2021.
[...]
So this brings us to the end of our list of the 10 best Linux server distributions of 2021. We hope this was useful and helped you find the right Linux server distro for your specific needs and requirements.
All the server distros come with their own unique advantages and disadvantages, as you can see. If you are completely new, we recommend starting with a Ubuntu server. With time, you’ll understand what features you need and then migrate to a distro that delivers those functionalities.
But that being said, this is by no means a comprehensive list of all the best Linux server distros out there. So if your favorite distro didn’t make it up on this list, then feel free to mention it down in the comments along with why you prefer it over the options discussed here. We would surely like to know.

openSUSE "Leap" 15.2 - Any Good?
This is a review I've been wanting to write since forever. Having tried many iterations of SUSE Linux over its long life before, during and after the Novell era, it always left me feeling ambivalent. And I really wanted to like it. The last time I set out to write a review but then canned the idea was for 12.3, when images would work in VMware Player but did not boot on my real hardware. Now THAT is a long time ago and it also means a lot may have changed, hopefully for the better.
SUSE is known and often praised for their offering of a highly polished KDE desktop. This is what I will go for in this little experiment. On the download page we can choose between a netinstall image for openSUSE "Leap" approx. 125 MB in size for x86_64 and the full DVD image of 4.3 GB. This is the equivalent of the box set of olden days. Live images are available with the KDE Plasma and Gnome desktops as well as a Rescue Live CD which are all staying under 1 GB in size, but only the rescue image is small enough to burn to CD. All images can be written to USB and DVD. Community maintained ports are also available for ARM, the Raspberry Pi and PPC architectures.
Instructions to install or change to "Leap" as well as minimum system requirements are further down the page. Quite a traditional selection really. The web page layout is simple and clear and conveys the most pertinent information right away.
Years ago installing from live image was not recommended so the choice here is basically between downloading the entire library or the netinstall image. I decided to go for the netinstall. Not having an installable live image obviously robs us of the test run people have become accustomed to unless we down yet another image just for testing. I decided against that as we can see from the netinstall image whether openSUSE will boot up or not. The rest is just desktop showcasing.
I downloaded images for the x86_64 architecture.
