Recovering data from a corrupted os x image file

MacInTouch Home Page: "Steve Cooper managed to recover a lost FileVault image with some extra effort:

I had a FileVault image that was corrupted in such a way that I couldn't get access to its contents. The solution finally was to mount the image using Disk Utility (which was the only thing able to mount it, though even then it didn't appear on the desktop) then use Data Rescue to retrieve the files from it."

DCOM 10021 - one answer, but it's not free!

Windows XP: dcom error on xp after upgrade

My WinXP SP2 event monitor shows regular occurences of DCOM 10021 error. I figured this would be easy to track down on the net, but the ONLY possible answer is at the Experts-Exchange site. That site used to be free, but it costs money now.

Wow.

The public net has failed me!

The only clue is that it may be related to upgrading a Win2K Pro machine to XP Pro.

Update: I should have scrolled down below the ads. Looks like Experts-Exchange does post the answers after a while. The link referred me to www.eventid.net. Looks like this will be a pain to hunt down. Of course Microsoft's support site had nothing -- hmph.

Update 2: This is looking better. The EventID site is very useful, unfortunately it's part of the "invisible net" (not accessible to search engines). I don't have McAfee installed, but these descriptions are interesting:
If you have a McAfee product installed and you have recently applied Microsoft Windows XP Service Pack 2, then see the link to "McAfee Support Solution ID: KB37954" for information on how to resolve this problem.

Eric Ritchie (Last update 12/15/2004):
I found this error to be a DCOM issue resulting from improper Launch and Activation permissions for the McAfee Framework Service in DCOM configuration. To resolve the issue, I searched for the registry key mentioned in the event description (which turned out to be McAfee's Framework Service). I then opened the Component Services Administrative Tool, and opened the properties of DCOM Config.\Framework Service under Computers\My Computer. Under the Security Tab, I found that the Administrators Group was missing from the Launch and Activation Permissions (Custom Tab). Giving the Administrators group full access corrected the issue.

Blogger was a mess today!

Blogger has had good and bad days over the past 8 months, but the past few days were the worst ever. One of my postings was replicated six times; after the sixth occurence Blogger went down completely for about 18 hours. Their status site, status.blogger.com, had no report on any part of the outage.

I wish I were paying for Blogger so they'd be in fear of losing my business. Another disadvantage of a free service!

NYPL Digital Gallery: 275,000 images and counting

NYPL Digital Gallery

Bookofjoe pointed out that the New York Public Library now provides public access to their digital image repository:
NYPL Digital Gallery provides access to over 275,000 images digitized from primary sources and printed rarities in the collections of The New York Public Library, including illuminated manuscripts, historical maps, vintage posters, rare prints and photographs, illustrated books, printed ephemera, and more.
Wow. It's been a while since such a large repository has been connected to the web. It reminds me again how far we've come since Paul Kleeberg first showed me the minutes of a city council meeting in Australia using a Gopher client back around 1994. Even so, we're only at the start of this journey.
