From now on, Microsoft has integrated the Cortana voice assistant from the system level, enabling users to start Cortana and interact with Cortana in real time with system settings. Let's try the process of using Cortana as a Windows IoT core device with

Because I have been very interested in linux, I started an experiment with Raspberry Pi and set up a simple php server to run typecho.
However, the process is extraordinary, and almost every step is stuck. in addition, compared with WordPress, typecho has less data, which makes the process of solving the problem a little difficult.
The first is the Raspberry

So that your computer can connect to Raspberry Pi without entering a password. You only need to generate an SSH key.
1. Check for existing SSH keys (check the existing SSK key)
First, check whether your computer (the device you use to connect to Raspberry Pi) has an SSH key:
ls ~/.ssh

net.ipv4.ip_forward=1
Then, start NAT in the kernel:
sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADEsudo iptables -A FORWARD -i eth0 -o wlan0 -m state --state RELATED,ESTABLISHED -j ACCEPTsudo iptables -A FORWARD -i wlan0 -o eth0
