Volare is a Python package intended to manage PDKs supported by OpenPDKs. It is used by DFFRAM and other projects.
In the future it probably is supposed to handle other PDKs as well, but as of 2022 only the Skywater PDK from Google is available.
The following is a brief overview of how to use volare.
On my NAS server I use Snapraid to protect against data loss and to some extent data rott. I do backups too, but only about once a month and when all the stars align. Automatically and regularly scrubbing a Snapraid array is well advised to keep that data save.
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*)
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.
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.
Recently I purchased a Sipeed TANG PriMER development board featuring an Anlogic EG4S20 FPGA (codenamed Eagle S20). The only reason I bought the board was to see what Anlogic FPGAs are capable of, since I had never heard of that FPGA vendor before. No need to think twice when the board costs less than 20$.
Working on the command line in a Linux shell can be tricky at times. A frequent source of frustration is that tasks which are trivial with a graphical desktop environment can be seemingly much more difficult to achieve on the command line. For example switching between multiple running applications only requires one or two mouse clicks on a graphical desktop, but demands more arcane knowledge to do it on the command line.
When we learn the theory behind electronic circuits we often calculate the exact value a certain resistor, capacitor or inductance should have.
However, in reality there is no 23.94 Ohms resistor available as standard off-the-shelf (SOTS) electronic part. Go and check it if you don’t believe me.
