This documentation describes to install FFmpeg on nvidia/cuda container to use the Nvidia GPU to accelerate encoding.

If you want to know how to install FFmpeg with NVIDIA GPU on Linux, go to see that.

FFmpeg can support hardware-based decoding and encoding for Nvidia GPU card. With the help of Nvidia GPU, h264_nvenc can lead encoding speed with 5x faster than libx264 in GTX1080 card.

Let's see how to install everything one by one on the Nvidia CUDA Docker container nvidia/cuda:12.2.0-devel-ubuntu20.04, in which CUDA toolkit and GPU driver are already included.

The smallest unit of all texts we see on the screen is one character. But you may wonder about:

1. How one character is displayed on the screen?
2. How one character is kept in memory or disk in binary format(0 or 1)?

Let's dive into the Unicode to solve these questions.

In Unicode, a character maps to something called code point which is a magic number written as hex like: U+20AC and is still just a abstract layer.

How that code point is represented in memory or on disk?

UTF-8, UTF-16, and UTF-32 help translate unicode code point into binary data in 8-bit bytes which can be saved in disk or be transported in network.

UTF-8 is character-to-bytes(1 to 4 bytes) encoding standard across almost all system and application.

Learning and using the QEMU help me understand how the linux operating system works including fields:

1. Linux boot process.
2. Cross compile for target system(such as arm64) on host system(such as x86_64), and test the binary.

This document will present how to create and manage Intel VROC RAID on Ubuntu with mdadm utility(It should also work in other Linux).

For setting up Intel VROC RAID on Ubuntu in BIOS, go to see VROC Ubuntu Setup.

For creating software RAID on Ubuntu, go to see:

Ubuntu RAID.

What is RAID?

The Redundant Array of Independent Disks, commonly known as RAID, is a technology used to combine multiple physical disk drives into a single logical unit for the purpose of data storage and performance improvement.

This blog will demonstrate to set up software RAID on Ubuntu(It should also work on other Linux).

In brief, CMake is all about targets and properties

If autoSwitch is turned on, it allows Windows to continue looking for other auto-connected wireless networks while connected to the current wireless network. If a higher priority auto-connected wireless network than the currently connected wireless network comes in range, Windows will automatically connect to it instead.

It also needs to work along with priority setting.
