Beelink SER4 Review – Windows 11, Ubuntu 20.04, and “overclocking” AMD Ryzen 7 4800U SoC

Beelink has released the SER4 which is the latest in their ‘SER’ mini PC series and it features a Zen 2 AMD mobile processor. Beelink kindly sent one for review and I’ve looked at performance running both Windows and Ubuntu and dabbled with ‘overclocking’. Beelink SER4 Hardware Overview The Beelink SER4 physically consists of a 126 x 113 x 40mm (4.96 x 4.45 x 1.57 inches) square metal case. As an actively cooled mini PC, it uses AMD’s 7 nm Zen 2 Ryzen 7 4800U Renoir processor which is an eight-core 16-thread 1.8 GHz mobile processor boosting to 4.2 GHz with Radeon Graphics. The front panel has an illuminated power button, a 3.5mm headphone jack, a Type-C USB 3.1 port with Alternate Mode, dual USB 3.1 ports, and a reset pin-hole ‘CLR CMOS’. The rear panel includes a gigabit Ethernet port, a USB 3.1 port and a USB 2.0 port, […]

ASUS Tinker Edge R SBC with 3GB RAM, Rockchip RK3399Pro sells for $179

ASUS Tinker Edge R Pico-ITX single board computer with Rockchip RK3399Pro AI processor was first unveiled in 2019 with 6GB RAM, but a cheaper 3GB RAM version with 2GB RAM for the CPU, and 1GB RAM with the integrated NPU just showed up in my news feeds. Whether it comes with 3GB or 6GB RAM, the Tinker Edge R board should mostly be interesting for AI accelerated workload thanks to the 3 TOPS built-in NPU, as well as the two MIPI CSI camera interfaces. ASUS Tinker Edge R (3GB) SBC specifications: SoC – Rochchip RK3399Pro hexa-core big.LITTLE processor with 2x Cortex A72 cores up to 1.8 GHz, 4x Cortex A53 cores @ 1.4 GHz, an Arm Mali-T860 MP4 GPU up to 800 MHz with OpenGL ES 1.1 to 3.2, OpenVG1.1, OpenCL 1.2 and DX 11 support, and NPU delivering up to 3.0 TOPS System Memory – 2 GB dual-channel LPDDR4 […]

How to Install dnsmasq caching DNS server in Ubuntu

As you may have noticed in recent days, my domain registrar (HostFast) suspended cnx-software.com domain for what I believe are dubious reasons, meaning the site was inaccessible to the outside world and myself. I cannot do much about the latter and I’m held hostage to what the domain registrar’s will, but I was able to access my own website with my domain name after installing a DNS server through dnsmasq on my Ubuntu 20.04 laptop. Edit: most of the steps below are actually not needed in Ubuntu 20.04, since you could just edit /etc/hosts (step 4). I’ll just leave the instructions below in case somebody needs to install dnsmasq. Here are the steps I followed. Install dnsmasq

sudo apt install dnsmasq

1	sudo apt install dnsmasq

This did not work at first since systemd-resolved is already installed, so I disabled it by following instructions on askubuntu:

sudo systemctl stop systemd-resolved
sudo systemctl disable systemd-resolved
sudo systemctl mask systemd-resolved

sudo systemctl stop systemd-resolved

sudo systemctl disable systemd-resolved

sudo systemctl mask systemd-resolved

I then added name servers to /etc/dnsmasq.conf:

server=8.8.8.8
server=4.4.4.4

1 2	server=8.8.8.8 server=4.4.4.4

and cnx-software.com IP […]

Capyloon mobile Web-based OS works on Pinephone Pro, Librem 5, Pixel 3a

Capyloon is an experimental Web-based OS leveraging b2gOS that served as the base for the now-defunct Firefox OS. The developers’ goal is to provide an open-source OS improving privacy and user control through web technologies. It’s still early stage, and some of the technologies used include the IPFS protocol, WebAssembly plugins, and the Tor network. Capyloon is more like a new phone shell as it replaces Phosh when installing it in a Linux smartphone. The first version of Capyloon released last month worked on Pixel 3a, other Android phones through a generic system image, and 64-bit x86 Debian machines. But since then, the developers added support for Apple M1, and yesterday they released Debian packages for PinePhone Pro and Librem 5 Linux smartphones to run Capyloon on top of a Mobian image. Instructions are as follows: Download the Debian package for PinePhone Pro or Librem 5 Install the package withsudo […]
