i lost my file with the complete, detailed instructions on how I built/installed PHP5 and MySQL5 on my box.

Burn a playable DVD from a VIDEO_TS folder – Burn a playable DVD from a VIDEO_TS folder

After searching the forums and trying various things, I still couldn’t find a quick, reliable, free method of burning a VIDEO_TS folder to a pure UDF DVD, so that it would play in regular DVD players, as well trigger DVD Player to start up automatically. Anyway, as often is the case, Terminal had the answers. Just type in this command and change the paths to suit:

hdiutil makehybrid -udf -udf-volume-name DVD_NAME -o MY_DVD.iso /path/to/VIDEO_TS/parent/folder

Make sure that /path/to/VIDEO_TS/parent/folder is the path to the folder containing the VIDEO_TS folder, not the VIDEO_TS folder itself. Once the .iso file has been created, drag this to Disk Utility and hit the Burn button.

Adam James: Yes.
Adam James: It’s the name of your network.
You: do I need to turn on the Specific Access points settings?
Adam James: That you need to give the same for one network.
Adam James: You can turn on now, for the security….
You: and which router needs know which MAC address?
You: the A router, the B router, or both?
Adam James: Give on both.

MDD G4 owner report on using CHUD tools Nap mode for Cooler CPUs

Disabling CHUD Tools’ Hardware System control “Nap” mode was a common fix for the ‘chirping/squealing’ noise from the P.S. in G5s as mentioned in this previous article, but a Mirror Drive Door Dual G4/1GHz owner wrote that enabling Nap mode significantly reduced his CPU temperatures. The current CHUD tools version is 3.0.2 available from Apple FTP Developer Tools directory as well as the usual VT/MU sites. (BTW – a recent email from a MDD owner regarding overheating CPUs said it was

So I read this article. I have loudness from my very old dual-G4.

Temperature Monitor works – told me it was 91°F – and that it could be way off due to no real temperature sensing device.

Installed CHUD and fiddled with the Hardware system preference. It lets me set nap!

When I came into the office this morning the temp was 53°F.

The machine doesn’t “sleep” since it is a server.

Cool – really!
