As we know, Jupyter is an awesome tool for academics, AI, Data scientists, etc.

When I run some nodes for the IPFS filecoin ecosystem, some Data I need to know, data visualization is more clear for us.

So I use jupyter, cause I used it when we do quant-trading. everything is similar.

This time, I used jupyter docker image to host service on my server.

Visualize yourself mining process data.

I have used windows 11 several weeks ago for work.

There have some reasons for me why from Mac to windows:

1, WSL 2 provide full Linux support

2, Windows Laptop has Nvidia Geforce 3070 GPU and 64GB memory

I was working for blockchain development, such as Filecoin Lotus, Cosmos, Polkadot, BSC, etc.

Though I am going to develop a new chain for our new business.

Cause Windows every reboot, the wsl2 network IP address will be changed. so I need to update the proxy setting, so I can normally work, I am living in China.

#!/bin/bash

host_ip=$(cat /etc/resolv.conf |grep "nameserver" |cut -f 2 -d " ")
echo $host_ip

export ALL_PROXY="socks5://$host_ip:51837"
export HTTP_PROXY="http://$host_ip:1087"
export HTTPS_PROXY="http://$host_ip:1087"
                          

put the above lines in the bash script file, and source it.

If you want to add it into bashrc,

. "$HOME/enable_proxy.sh"

use env command to ensure the proxy settings successfully.
