btscanner: Update OUI List – Vendor Organizationally Unique Identifier List

If you use btscanner, which is a Bluetooth scanner found in Backtrack Linux, a lot like I do then you will notice that the Public OUI list included is pretty far out of date. The OUI or Organizationally Unique Identifier list is what matches MAC addresses to manufacturers or vendors. This is how you can determine who produced a specific product that is talking on a network for instance a Bluetooth device that is attempting to communicate with your phone or your computer.

Developer Options Not Showing On Google Nexus 7 Android Version 4.2.1 Build JPO40D

I just started getting a little time to play around with my new Google Nexus 7 32GB tablet and so far I am loving it. It will be the first Android device that I have spent much time on so its pretty exciting! I love the size of the Nexus 7 because it still fits in my pocket and will be perfect to read or watch movies while flying around the country. Obviously the first thing I wanted to do was root the Nexus 7 so I could have full control of it but the Developer Options setting was missing from my Android 4.2.1 Settings screen. Below I show an image of my default Android Settings screen and explain how to display the Developer Options menu item in Settings.

Technology Errors

A Runtime Error has occurred. Do you wish to Debug? – Internet Explorer 5 – Windows 2000 SP2

I have been working with some older versions of Windows 2000 lately including Windows 2000 SP2 or Service Pack 2. On this version of Windows 2000 SP2 the version of Internet Explorer or IE is 5.00.3315.1000 which is completely outdated. I doubt that many others will be running into Runtime Errors however it is possible even in more current versions of Internet Explorer though the setting that resolves this issue is enabled by default so unless you have modified the settings you should not run into this issue. Below we describe the error in more detail and how to easily change a single settings to fix the problem.

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.
