iTunes Problems Downloading Some Purchased Items

I had an iTunes issue occur recently that seemed to be caused by one of two recent actions:

1. After following the steps to share music on a single computer with multiple users. iTunes: How to share music between different accounts on a single computer
2. While logged in as myself with my iTunes account I logged into iTunes with another account and authorized some songs.

An example of the error message from iTunes:

There were problems downloading some purchased items.For more information on the items that could not be downloaded, click below.
There was a problem downloading “Example iTunes Item”. You do not have enough access privileges for this operation.Please check that the connection to the network is active and try again.

Here are the steps to correct the issue:

1. Close iTunes
2. Get Info (Cmd-I) from your iTunes Folder
3. In order to use Finder to make changes you will have to click on the lock at the bottom right and enter the credentials of a user with permission to make changes.
4. Verify that the folder is unlocked (the Locked item in the top grouping is not checked). Note this is not the same as clicking the Lock on the previous step.
5. Verify your user name is listed under Sharing & Permissions and you have Read & Write Privileges
6. To add your user name click +, select your user name, and select Read & Write Privileges
7. Select the gear button (bottom of the Info dialog) and select Apply to enclosed items.

Bletchley, England: Powering Hendrix and saving the free world!

Marshall Amplification plc. a.k.a. Marshal Amps and Bletchley Park National Codes Centre are located about a 0.5 mile from each other as shown on Google Maps.

History

Bletchley Park was the main site of the British decryption facilities. The Bletchley Park Wikipedia post goes into the exciting history and has many links to key people involved. Many top mathematicians and cipher analysts worked there.   

One of them was Allan Turing, the mathematician who became influential in the development of computer science.

And I learned that three Polish mathematicians and cryptologists were the first to solve the plugboard-equipped Enigma machine in 1932. That was the main cipher device used by Germany, and their work gave the British a jump start on reading the Enigma of World War II.

Pictured on the right is the Colossus computer invented by Tommy Flowers at Bletchley Park. These were the world's first electronic, digital, programmable computing devices. They used vacuum tubes to perform the calculations. And it was vacuum tubes that powered Jimi's Marshall amps about 20 years later! To this day some of the most expensive amps are vacuum tube powered. Most amps today use solid state electronics (built with solid materials as opposed to the somewhat fragile glass vacuum tubes).

Movies

Relevant movies include Sekret Enigmy, a 1979 Polish movie with English subtitles that is likely more historically accurate than most. An American made movie U-571 (2000) was enjoyable, but it was not very accurate.

And on the Hendrix side we have Jimi Hendrix - Live At Woodstock released in 2005 about 389 years after the event.
