How To Setup A Free Proxy Server Using Amazon Services CentOS

Tinyproxy is a small and fast HTTP/HTTPS proxy server daemon.

Open Amazon Web Services (AWS) Account

Register for a free AWS account. You will need a valid credit card to register. The free tier allows you to use their services free (limited) for up to 12months.

Create an EC2 Instance. Here's a great tutorial on how to do it. It includes how to connect to it via SSH.

Install tinyproxy

Connect to your instance via SSH and issue the following command:

yum -y install tinyproxy --enablerepo=epel

Configure tinyproxy

You must allow your IP to connect to the server

sudo vim /etc/tinyproxy/tinyproxy.conf

Allow XXX.XXX.XXX.XXX #Your public IP address

Then we need to make sure it runs even on restart.
sudo chkconfig tinyproxy on
sudo service tinyproxy start

Microsoft Announced Partnership With the Arduino Community

Microsoft released as open source a Windows Virtual Shields for Arduino technologies and a wireless access application called Windows Remote Arduino.

With Windows Virtual Shields for Arduino, users can tap into the incredible power of their Windows 10 devices through wireless protocols. For example Lumia 530 contains a lot of Arduino Shield capabilities and allows designers/makers to connect all those components seamlessly. Imagine being able to create an Arduino project that includes GPS, Web connectivity/parsing, touch display, speech technologies and more!

With Windows Remote Arduino developers can create a wireless interface to Windows 10 devices as if they were physically attached to an Arduino Shield. Arduino functions can be accessed directly from the Universal Windows Application.
