Ubuntu Touch to Be Officially Supported on Librem 5 Open Source Smartphone

Ubuntu Touch looked really promising as a Linux mobile operating system supporting mobile desktop convergence, so eventually some people would have been able to use a single device for their mobile and desktop needs. If was not for lack of trying, but sadly Canonical had to end the development of Ubuntu Touch due to lack of interest from phone manufacturers and the community at large, focusing their resources instead of the cloud and IoT. But some people were still very enthousiastic about Ubuntu Touch, Unity and convergence, so since the code was open source, UBPorts continued working on Ubuntu Touch on their own. UBPorts developers have now collaborated with Purism to make Ubuntu Touch one of the officially supported operating systems for the Librem 5 smartphone. Librem 5 will still ship with GNOME based PureOS, but Purism will support customers who want to easily install Ubuntu Touch or PureOS with […]

GalliumOS is a Linux Distribution for (Intel) Chromebooks & Chromeboxes

When I wrote about Crostini VM to run Linux apps on Chromebooks last week, I was informed about GalliumOS, described as a fast and lightweight Linux distro for ChromeOS devices – meaning Chromebooks and Chromeboxes – that is based on Xubuntu. Compared to ChromeOS, GalliumOS – and other Linux distributions – provides the ability to run more programs and more flexibility, and GalliumOS is said to deliver improved performance, longer battery life, better touchscreen support, etc.. compared to competing Linux distributions. You can go over the Download page to retrieve an image for your Chromebook or Chromebox, and either replace ChromeOS or go for a dual boot setup. The distribution does not support any Arm Chromebooks for now, and only works with some Intel devices with or without caveats depending on the model used. Check out the hardware compatibility matrix for details. The source code can be found on Github. […]

24 Orange Pi Zero Boards Cluster and ArmWizard’s Debian Image

ArmWizard forum member “-W.-” needed a cluster to test his firmware build and deployment solution for Orange Pi Zero boards which can deploy the firmware to multiple boards from one single board. So he procured 24 Orange Pi Zero boards, a 24-port switch, some USB hubs and debug board, as well as some other accessories, power supplies, and two wooden planks. That’s the results after assembly. So we have 4 tower of six Orange Pi Zero boards fairly neatly connected to the 24-port Ethernet switch with 30 cm Ethernet cables, and four black USB hubs for the USB to TTL debug boards. The side view below shows the boards are powered by micro USB cables connected to three different power supplies, cooling achieved via four fans, and the power extension is hidden right underneath close to the Ethernet switch. The cluster will also be used for machine learning latter on, […]

My Experience with Dodocool AC750 WiFi Repeater

A while ago, I tested Dodocool DC30S USB type C Hub with HDMI, USB port, and a card reader, and recently the company asked me whether I wanted to review another of their accessories. My ISP has recently taken the habit of being down several hours each month, so I rely on my neighbor’s WiFi (with he’s permission) in those case, but since the signal is too weak, I’m using a wireless audio streamer and a power bank to extend the signal and connect it to my router using WDS Bridging. Then I saw Dodocool DC24 802.11ac WiFi repeater, so I decided to give it a chance. Dodocool DC24 A750 Repeater Unboxing I received the device is a cardboard box with some specifications. It’s an AC750 router/repeater with 300 Mbps @ 2.4 GHz + 433 Mbps @ 5 GHz. The product page linked above has some more details with the […]
