Google Calendar – Can Only Share Calendar In See Only Free/Busy (Hide Details) Mode

This morning I was attempting to share one of my Google Apps Google Calendars with my default Gmail account with full access rights however it kept changing the sharing mode from Manage Changes and Manage Sharing to See Only Free/Busy (Hide Details). At first I thought it had to do with the calendar I was sharing too already being shared back to this calendar with lower calendar event rights however after I deleted all traces of the calendar I was still running into the same issue. Turns out the issue was in the Google Apps dashboard for the Google Apps Calendar I was attempting to share to the normal Google account. Below I describe the issue in more detail and what settings need to be modified in the Google Apps dashboard to allow you to share Google Apps Calendars with full admin privileges.

Backtrack Linux offers a lot to people of all skill sets and I really appreciate the thought that the developers have put behind making this a operating system platform that is friendly to all. In my experience there are penetration testers or information security enthusiasts of all levels and having Backtrack as a platform to learn from is great. The apache start menu item in Backtrack simply starts the Apache web server and is explained in more detail below.

Restart Services On RackSpace Managed Nodes That Require sudo Rights

Recently I was working on a project that was using RightScale to manage RackSpace cloud nodes. One of the requirements of the project was to have application nodes scale automatically thus they were required to automatically install software, configure settings, and start services automatically on the RackSpace CentOS nodes being used. Most everything was fairly straight forward however some of the services we were using would not start properly and initially because of the lack of logging from the services we were unable to figure out what the problem was. Below I describe the problem in more detail along with the solution which involved updating a configuration file on the CentOS Linux servers and then restarting the services.
