First Steps with Google SkyWater PDK – Free Open Source Silicon for Everyone

For a while now Google has been collaborating with SkyWater Technology to create what many refer to as free and open source silicon (FOSSi). The project gained traction in 2020 and is continuing to gain momentum.
The proclaimed goal is to bring chip design to the masses and enable everyone from academia, industry and makers to create their own computer chips. If this plan succeeds it would mean a considerable shift in the chip industry which traditionally is very secretive and dominated by just a few big corporations and their partners, connected by a opaque web of interdependencies. (Surely Google counts as the underdog in comparison *cough*)

Installation and Configuration of MiniDLNA/ReadyMedia

This is a very brief article or rather a reminder to myself, about how to install MiniDLNA on Ubuntu Server 20.04. I always knew this piece of software by it’s old name MiniDLNA, but apparently it was renamed and is now called ReadyMedia. There don’t seem to be many changes below the hood though.

MiniDLNA is a light-weight media server using the DLNA protocol. Through MiniDLNA a library of media files is created which allows a user to very conveniently browse through the files and start audio and video playback. Most SmartTVs and Android phones support DLNA out of the box.

Setting up Wireguard on Ubuntu

Wireguard is a modern VPN protocol allowing secure and confidential communication between a network of peers. Wireguard is based on the concept of private-public key cryptography and a number of other modern cryptographic algorithms. Have a look at the wireguard white paper for more details.

Wireguard Requirements

Since Linux kernel version 5.6 (late March 2020) wireguard is an integral part of the Linux kernel. That means Linux distributions using a kernel >= 5.6 do not need to install any additional packages in order to support wireguard.

First Steps with the Tang Nano FPGA Development Board

The Tang Nano is a very very low cost FPGA development board by Sipeed featuring a GW1N-1-LV FPGA produced by GOWIN Semiconductors. GOWIN is another Chinese chip manufacturer entering the FPGA arena, like Efinix and Anlogic.
The GW1N-1-LV is the smallest member of GOWINs “Little Bee” series, which consists of small footprint instant-on FPGA devices for IoT and interfacing solutions.
