Installing python cx_oracle on Ubuntu

First of all, it just seems like doing anything with Oracle is obnoxiously painful for no good reason. It's the nature of the beast I suppose. cx_oracle is a python module that allows you to connect to an Oracle Database and issue queries, inserts, updates..usual jazz.

sudo apt-get install build-essential unzip python-dev libaio-dev

Step 2. Click here to download the appropriate zip files required for this. You'll need:

XenServer Notes

Citrix Xenserver

Citrix Xenserver is a beautiful open source (from 6.2 edition and later) hypervisor that tries to grab as much as possible market share on virtualization/cloud world. It carries many years of development efforts by Citrix, many well established implementations and a broad support community. XenMotion, High Availability and all the great features of Xenserver are available on the licensed and unlicensed versions of the hypervisor.

The licensed version includes automated patches and updates through XenCenter console and 24×7 Citrix Technical Support. On the unlicensed version, the administrator should apply the xenserver patches by himself through an ssh console. XenCenter still notifies the availability of new patches.

How to use PAYMILL with Squarespace

How to use PAYMILL with Squarespace

What follows is not a step-by-step guide for using PAYMILL. You will need a some knowledge of Javascript (inc. jQuery), a bit of PHP and preferably some experience with cross domain requests. Additionally, you will have to upload files to Heroku, which requires Git and terminal commands, or any other service that you can host the PHP files.

Let's look at a brief overview of the process:

  • The User fills in their credit card details in their browser;
  • The PAYMILL JS library generates a token on PAYMILL's servers and hands it back to the browser;
  • The browser sends this token to our own server;
  • Our server uses the PAYMILL server-side library to submit the charge to PAYMILL;
