Tenets of AV1 Encoding

AV1 is a next-generation video codec developed by Alliance of Open Media to facilitate VOD, storage and live-streaming. It's usually paired with Opus audio codec, stored in MP4 (ISOBMFF) or streamed using HLS (HTTP Live Streaming). SVT-AV1 is currently the best production quality encoder available (the matter of discusssion here).

Presets

Quoting the SVT-AV1 documentation:

Presets control how many efficiency features are used during the encoding process, and the intensity with which those features are used. Lower presets use more features and produce a more efficient file (smaller file, for a given visual quality). However, lower presets also require more compute time during the encode process. If a file is to be widely distributed, it can be worth it to use very low presets, while high presets allow fast encoding, such as for real-time applications. >

Ubuntu on Asus ROG Zephyrus G14 2021 (Setup guide)

Here is a way to do a robust install of Ubuntu (+ optional Windows 11 dual boot and LUKS encryption) on an Asus laptop, with minimal usable hardware support, without a significant amount of tinkering that may break in future or require frequent technical attention.

In summary, the key thing is to have an up to date kernel, which usually means disabling secure-boot and installing the latest stable (6.0+) using mainline or xanmod, and as well as making sure the latest nvidia driver and dkms is installed.

Specs:

Model Asus G14 2021 (GA401QC)
AMD R7 5800 8 core 16 thread (onboard Radeon graphics)
NVIDIA RTX 3050 4GB (60W +15W boost)

Grab all your wireguard configs from Mullvad and dump them in a folder. For this test, this folder is ~/wireguard/.
Add the following function to generate a list of all servers you have configs for

lswg ()  { 
    ls ~/wireguard/ | cut -d '-' -f 2 | sed 's/\.conf//'
}

Ping each server 10 times to determine latency.

lswg | xargs -I {} ping -c 10 {}-wireguard.mullvad.net | tee mullvadwgstats
