Installing CUDA

Warning: Today's date is April 14th 2021, and therefore these instructions might no longer be applicable for you!

Too Long Didn't Read (TLDR): Getting the error message below after installing CUDA? Download the .run file and follow the non (optional) code snippets to update your NVIDIA driver.

I started off by installing Ubuntu and afterwards I PRECISELY followed these installation instructions from NVIDIA on how install CUDA. I recommend you do the same.

Final change of plans (March 8, 2024)

I don't see that many people are using Starlight on modern versions anymore. As such, I don't see any reason to continue to maintain the mod versions, given that they do have real mod conflict issues with other mods. Starlight is also not neccessary to use on 1.20.x anyways.

Starlight may make a return in a future project of mine, but for now I am ceasing to upload new mod versions and commit updates to the github. If you want Starlight on the server, you will need to use Paper or one of its derivatives.

This Gist is about how I use PyAudio, NumPy, and Matplotlib to plot freqency spectrum of system sound or microphone.

IaaS指提供系统（可以自己选）或者储存空间之类的硬件，软件要自己手动装；PaaS提供语言环境和框架（可以自己选）；SaaS只能使用开发好的软件（卖软件本身）；BaaS一般类似于非关系数据库，但各家不通用，有时还有一些其它东西。

About YUV formats

First of all: YUV pixel formats and Recommended 8-Bit YUV Formats for Video Rendering. Chromium's source code contains good documentation about those formats too: chromium/src/media/base/video_types.h and chromium/src/media/base/video_frame.cc (search for RequiresEvenSizeAllocation(), NumPlanes() and those kinds of functions).

YUV?

You can think of an image as a superposition of several planes (or layers in a more natural language). YUV formats have three planes: Y, U, and V.

Y is the luma plane, and can be seen as the image as grayscale. U and V are reffered to as the chroma planes, which are basically the colours. All the YUV formats have these three planes, and differ by the different orderings of them.
