Configure virtualbox data center which uses ubuntu 20.04

In this blog, I will show how to configure network in ubuntu 20.04 to create a small data center with virtualbox to simulate cloud vps in local development environment. The overall procedure is to, first, creating a virtual machine with 2 bridge network adapters attached. Then, making configuration for the network adapters with netplan . After that, cloning 2 more virtual machines and adjust the ip addresses in the network configuration. Create a virtual machine and configure its network Create new virtual machine and attach bridge network adapter to Adapter 1 and Adapter 2. Let's put the name for the machine as red Find out what are the name of the network interfaces using command ip a Then modify the file with content similar to below. Copy the content below to /etc/netplan/00-installer-config.yaml , then modify the ethernet interfaces to match with your virtual machine's interfaces. After that, run netplan apply for the ne

The first taste of Rust - A simple you tube downloader

Recently, I just learnt Rust and using it to write a simple youtube downloader with reference from node-ytdl . In this blog, I would like to share the code and how did I make it. You can find the full source code here . Install development environment I am using Windows 10 and scoop package manager. Therefore, I use the following commands. Run scoop install rustup-msvc to install rustup . Run setx "%path%;%USERPROFILE%\\scoop\\persist\\rustup\\.cargo\\bin" to add rustup to the path. Restart termial (git-bash in my case) and check the installation with rustup --version; rustc --version; cargo --version Export custom RUST_HOME : export RUSTUP_HOME=$HOME/scoop/persist/rustup/.cargo/bin/rustup Install a toolchain for rustup : rustup toolchain install stable-x86_64-pc-windows-msvc Setup project Run cargo new simple_rust_youtube_downloader --bin && cd simple_rust_youtube_downloader to create and navigate to the project. Add these dependencies to
