A reader sent me some information on replacing the Apple power supply for the Cinema Display. He realised that a 24V 'LED Strip' power supply should meet the power requirements for the display.

The power supplies sell for around $20 which is a considerable saving compared to the Apple version around $100 to $200 (depending on usage). He was in the process of testing 2 'dead' displays and was able to exchange parts between them to diagnose the problem for each display… Read more »

Wifi deployment of Macbook Air's

Note to self…

Deploying multiple Macs over 802.11.n isn't really practical.

Using a 1.27GB Deploy Studio netboot set to boot one Macbook Air took 2:30's to get to the DS runtime to be able to select a workflow.

A test with 6 machines booting in parallel took 11 minutes for 5 of them to get to the same usable state. One machine failed to boot the netboot set & it sat the at the grey Apple screen, so it probably wasn't pulling in the netboot image over wifi.

These times don't include running any restore workflows, so actual restoring could take hours for a large master image. Wifi doesn't support multicast streams so each client needs to maintain a single connection to the server.

Import local hosts into VirtualBox guest VM

I have made a simple script to take the locally defined hosts & import them into a Windows virtual machine running on VirtualBox.

It means local testing domains defined in your Macs /etc/hosts file can be viewed from the Windows environment, combined with xdissent's ievms script it makes handling virtual machines a simple process.


The script creates a batch file & then runs it inside the VM. The VM requires the virtualbox guest additions. Read more »

Reverting PHP 5.3 to 5.2.10 on Snow Leopard

Snow Leopard ships with the latest version of PHP, version 5.3. Unfortunately Drupal 6 will produce error notices due to the use of deprecated functions. It seems the solution is to 'hack Drupal core' or use an older version of PHP. It seems likely that Drupal 5 won't be updated to support PHP 5.3. Read more »
