iMac G5: fans running more often

My 20" iMac fans run often nowadays - a load that was tolerated before drives fans up. No idea why. In the past Canon's crummy printer drivers caused this kind of problem with a bad print job (printing is an OS X weakness), but Activity Monitor (show all) has no bad news.

CPU temp is about 168 by Thermograph measures. High, but unfortunately not too high by the low standards of the "30% failure rate" 20" G5 iMac.

iMac G5 constant fan noise - Mac Forums has some hints. I'll try those and update here. Cleaning out the air ducts sounds harmless enough.

I wonder too if Apple, knowing the problems with the design of this machine, has tweaked the temperature response curve to lower the threshold for high speed fans.

PS. I'm posting this using Firefox 2 RC-2. I love the inline spelling check!

Update 10/8/06: Seems better. Here's what I did:
  1. Checked Activity Monitor for any hung processes (none found, be sure to view ALL processes)
  2. Reset the SMU (System Management Unit)
  3. Opened up the iMac and blew out clouds of dust from vents, etc.
  4. Changed performance to Highest (this is odd, but it came from MacOS X Hints).
I'll see it it stays better. Hard to say what worked, I didn't have time to mess with this so I did everything that seemed reasonable.

Update 1/24/2010: Four years later I noticed this again. I reset the SMU and it improved. Thanks to Google custom search I found this old post and new what to do.

Camino: Command-click to select table cells

In Camino, my current OS X Gecko web browser, you can command click to select table cells and copy and paste them. Surprisingly useful. I think this is probably true of Firefox too.

Gordon's Tech: Google's splog mislabeling continues

Google's splog (spam blog) identification process reminds me of our incompetent FBI's No-Fly list. In the last few weeks I've twice gotten the "captcha of doom" requirement on posting. The good news is that if you respond rapidly Google seems to remove their sanction pending review. There's no sign anything has happened though, if you enter the magic URL: h
http://www.blogger.com/unlock-blog.g?blogID=123454 where you replace the 123454 with the Blogger blog ID.

Google spreadsheets: Lord this is buggy

I've been using Google Spreadsheets for some collaborative projects. Good Lord, this is buggy stuff. Slow too. Google has a reputation for calling release-quality products "beta", but in this case alpha is the right label.

It's a great idea, but there's a lot of work left to do.

Adobe Contribute for OS X

Adobe - Contribute - a curious application which sounds vaguely like a modern equivalent of Microsoft's old FrontPage, but for OS X. Free trial, cost $150. Not obvious how well it works with Blogger.

I am likely to give it a try, but probably in the new year after the bugs get worked a bit.

Disappearing Aperture Libraries: very nasty bug

A very nasty bug. To recover you need to switch to an earlier version! Affects people who named a project using an initial "." character. That was legal in the old version, illegal in the new. See Aperture: Folders or Projects missing after 1.5 update installed.

From other kb articles it sounds like a patch for Aperture is on the way soon. I'll be waiting until they finally fix the non-functional date metadata.

Mac Windows integration: avoid special characters

The advice from this specific kb article is probably applicable to any mixed Windows/Mac environment. Anything that's "named" should stick to the old "non-special" ascii character set, including usernames and passwords ...
Mac OS X 10.4: Can't print to a printer shared by Microsoft Windows

...

* The printer's shared name contains a space or special character (see below).
* The name of the computer sharing the printer contains a space or special character.
* The Windows user's name or user's password contains a space or special character.

What's a 'special character?' It's a typed character other than A-Z, 0-9, !, $, *, (, ), _, , -, ' . .

The following are not special characters and are OK to use in the printer name, Windows computer name, Windows user name, and Windows user password:

A a B b C c D d E e F f G g H h I i J j K k L l M m N n O o P p Q q R r S s T t U u V v W w X x Y y Z z 0 1 2 3 4 5 6 7 8 9 0 . ! $ * ( ) _ - '"
By the time we all support UTF-8, we'll need to move to a character set that supports non-human languages ....
