Todo App using Spring Boot REST API

0. Overview We will implement simple Todo List app, with client using jQuery and backend use Spring Boot REST APIs. 1. Installation Spring Boot If you have both Ruby on Rails and Java Spring boot on the mac, when you type spring command, it will run spring from Ruby! To avoid that, let do symlink

Generating a Dart client for an App Engine Cloud Endpoints API

This article will show you how to generate a Dart client library for Google App Engine Cloud Endpoints. First we need to download root API discovery document : Now we have apis.json, create a folder name discovery and put apis.json in. Second, we will install This will create a new Dart package with generated

Virtual Private Network for Multiple Platforms – Part 2

In the previous part, we already finished setting up Server node and Deep learning node, now it’s time to setup Mobile node (to control other servers securely). Current VPN setup: Server node (servernode, it has public IP address, and VNP IP will be – done in part 1 Deep Learning node (odroidnode, VNP IP address

Virtual Private Network for Multiple Platforms – Part 1

For Smart home servers or local deep learning server, you may want to keep them inside a private network, or local network for security reason. To access those servers from outside, it’s necessary to setup a virtual private network (VPN) Assume that we have 3 nodes: Server node (servernode, it has public IP address, and
