nginx : set up http/https conf for your server(Ghost)

Let me use cluster.errong.win as a example.
All you need to do is replace the server name and port.
All reqest to cluster.errong.win will be proxyed by http://127.0.0.1:6666

http conf

server {
    listen 80;
    listen [::]:80;

    server_name cluster.errong.win;
    root /home/errong_leng/www/cluster/system/nginx-root;

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $http_host;
        proxy_pass http://127.0.0.1:6666;
        
    }

    location ~ /.well-known {
        allow all;
    }

    client_max_body_size 50m;
}

enable http server to nginx

ln -sf /home/errong_leng/www/cluster/system/files/cluster.errong.win.conf /etc/nginx/sites-available/cluster.errong.win.conf
ln -sf /etc/nginx/sites-available/cluster.errong.win.conf
/etc/nginx/sites-enabled/cluster.errong.win.conf

Use Let's Encrypt

Let's Encrypt is a free, automated, and open Certificate Authority.

https conf

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;

    server_name cluster.errong.win;
    root /home/errong_leng/www/cluster/system/nginx-root;

    }

    location ~ /.well-known {
        allow all;
    }

    client_max_body_size 50m;
}

enable https server to nginx

ln -sf /etc/nginx/sites-available/cluster.errong.win-ssl.conf

android studio : CreateProcess error=216, This version of %1 is not compatible with the version of Windows you're running

Error

CreateProcess error=216, This version of %1 is not compatible with the version of Windows you're running. Check your computer's system information and then contact the software publisher

Solution I

Your sdk location not match, select the real sdk location
Someone says it works, but not for me.

Solution II

REASON

This happens because for now they only ship 64bit JRE with Android Studio for Windows which produces glitches in 32 bit systems.

SOLUTION

do not use the embedded JDK: Go to File -> Project Structure dialog, uncheck "Use embedded JDK" and select the 32-bit JRE you've installed separately in your system
decrease the memory footprint for Gradle in gradle.properties(Project Properties), for eg set it to -Xmx768m.

react-native : navigate/load url via WebView

No Image, No Truth

use WebView component in reactnative.

var {   ....,   WebView, } = React; 

initial state give a default url

getInitialState: function() {  return {   url: '', // or default url  }; }, 

render with state url

<WebView ....your styles, properties   url={this.state.url} /> 

Navigate/load codes

load() {  this.setState({url:'http://google.com'}); }
