[email protected] didn’t work so I am trying you here

I got this from a recent Tidbits and it reminded me of your prime number program. This guy has a more complex program (albeit nearly as pointless) but has the background to have tried it on a proud line of mainframes and modern PC’s.

Power Macintosh G3: The Cannonball Express

——————————————

by Rick Holzgrafe

The Cannonball Express was the fabled train that was so fast it

took three men to say “Here she comes,” “Here she is,” and “There

she goes.” Computers are fast too, although unlike trains, most

aren’t self-propelled. What makes a computer fast, and how much

effect does software design have? How much faster are today’s

computers than yesterday’s? Recently I revisited some of these

questions, beginning with a trip down memory lane.

iBook Power Cable Fix

When Mary Clarie turns 10, she gets to play pool at Gramalie and Grandad’s because of the “double digit” rule. She pushed Grandad with an “I’m oh eight (08) so I can play!” Didn’t work.

She also gets to use the Apple iBook again after being banned with a “two strikes and your out” rule. The first strike burned out the adapter plug with a short. ($80.) The second strike sliced (but did not break) the new replacement. The cool all-white adapter with it’s orange/green glowing plug now has uncool looking black electrical tape along the middle of the slim cord.

The slim cord is a real weakness, especially the way it follows around the wireless iBook as needed. Peter says Tesla was working on wireless power.

I’m going to try to repair the shorted cable.

According to MacEroni I can wire in one from Lind Electronics. It won’t have an orange/green glow, but it will give us an alternate power supply.

Firewire and FlowerPower

Nicole’s FlowerPower Mac had a CD drive running OS X Jaguar (10.2). Our iMac 17″ Flat Panel came with OS X Panther (10.3). I was troubleshooting a problem she was having with her keyboard, and decided to upgrade her system. The problem was, the Panther install was on a DVD, and the Flower Power only had a CD Drive.

I searched far and wide using Google trying to figure out how to boot up the contents of the DVD on her Mac. You can’t just copy the files over. Can’t boot off a network-shared drive (without a Mac OX Server.) The DVD contents are way too large for a CD. I don’t have an external drive.

Then I ran into the concept of using Firewire to connect two Macs. One Mac can be set to boot up in “Target” mode by just holding down the letter “T” when booting up. I was able to start up Nicole’s Mac in target mode, then connnect the new iMac via a Firewire cable. The FlowerPower Mac’s hard disk acted just like a second hard drive on the newer iMac, so I was able to set Nicole’s hard drive to be the boot drive for the iMac. In the photo below, the 17″ flat panel iMac is using the FlowerPower’s hard drive to start up, so it looks like the FlowerPower Mac is inside the iMac. (The FlowerPower’s screen is showing the Firewire icon meaning it is in target mode.) The glowing blue Firewire LED makes it all look cooler.

I was able to use the new iMac’s DVD to upgrade Mac OS X on the FlowerPower Mac. Apple is always building unexpected but useful things like “Firewire target mode.” (It is really like built-in SCSI in older Macs…. which was advanced for its day.)

The other cool thing about this photo is that I recently learned how to use the manual mode on my digital Cannon. This allows for an otherwise impossible shot like this where the screens would be overexposed because of the dark surroundings.

Mac OS X 10.3.4 Disk Mount Problem

Found this tip. Steps 3 through 4 solved my problem of disk images not mounting.

macosxhints – 10.3: Repair a disk mount problem after 10.3.1 upgrade

Repair a disk mount problem after 10.3.1 upgrade

I bought an iBook with OS X 10.3 and upgraded it to 10.3.1. After the upgrade, I could not mount disk images from my hard drive or burn CDs. Apparently this is a common problem after upgrading. I phoned AppleCare and this is what they had me do:

1. Run /Applications/Utilities/Disk Utility.

2. Click on “Macintosh HD” in the left column and then press the “Repair Disk Permissions” button. I don’t think this step was part of the solution to my problem.

3. Delete the file called /System/Library/Extension.kextcache

4. Delete the folder called /System/Library/Caches/com.apple.kernalcaches/

5. Restart

After these steps, disk images mount properly and the CD burner works.
