I scanned the syllabus. Definitely an MIT perspective on medical informatics! I'll likely use some of this material when I teach at the U MN again this fall.

Full text search in 10.4 and elsewhere

Daring Fireball: Spotlight on Spotlight

... Both metadata collection and full-text indexing depend on cooperating per-file-format Importers, either written by Apple or by third parties. Like Google, no matter how much text an Importer provides, Spotlight only cares about the first 100K of raw text.

Importers are fired on every file the moment it is created, saved, changed, or moved, including when files are made available through a newly mounted drive. Performance is said to be excellent in every case except network-mounted home directories, which are bedeviling on several levels and on which they’re still working.

Interesting limitation of both Google and OS X Tiger's full text indexing ignores much past 100K. That's bigger than the raw text content of most documents, but it leaves books out of the picture. For my taste it's the right choice. I hope I can choose which folders NOT to index.

I imagine I'll stay with 10.3 on my iBook -- I just don't have a big enough drive on that machine. Tiger I'll get with my next machine.

Apple - Discussions - Replacement iPod is INDEED defective

Apple - Discussions - Replacement iPod is itself defective: "Ok, this is now is the third replacement. I've been through four 30GB G3 iPods now.

It arrived very quickly -- expedited service since it was my 3rd return.

I recharge it. Go to use it. The central button doesn't work. I can navigate the top menus, but I can't do anything else. I can reset it, no change.

If anyone wants to discuss this with me directly my email is jfaughnan@spamcop.net."

Wow. This is very impressive. I'm pretty convinced by now that Apple really can't service iPods. Their entire service routine must be a clever scam. They know sooner or later I'll get tired of calling AppleCare for a return.

They are rapidly turning into a seriously scummy company. I'm going to use Minnesota's consumer protection process.

Update:

I called AppleCare and was good and patient. When I was asked to reset I said I'd already done it, but offered to repeat. That was good.

The first time I'd reset by myself I forgot to switch the hold toggle on and off. The hold toggle turns power to the buttons on and off. That was a critical step. With it the reset cleared the problem.

It appears some combination of pressure on the central button (perhaps in shipping) and power drainage can cause the button to be locked out.

So this iPod is now working.

I'll put a hold on my letter to the state attorney general until I see how this replacement does!

updateNope, it's really broken. Lock switch is malfunctioning. Now for replacement number 4, and the letter to the state attorney general.

Update 2: The problem is more subtle than just a bad lock switch. At varioous times, particularly when withdrawing a fully recharged iPod from the cradle, the buttons are totally inoperable. Reinserting into the cradle may restore functionality. I think it's likely a somewhat flaky circuit that can be perturbed by small voltage fluctuations.

Fix for SMB share mount problem for OS X 10.3.4

Mac OS X Panther (10.3.4): "SMB Share Mount Solution

Peter Stys
I have a solution to the problem submitted below and posted on your web site [Jun. 10 ]: 'I upgraded Macs machines running 10.3.4 with the latest Security Update 2004-06-07, and ever since I cannot mount SMB shares from our Windows 2000 server, with an error -36'

A colleague of mine suggested using the Keychain Access utility to delete all entries related to the problematic Windows server and this solved the problem: the share now mounts fine. You may want to post this for other readers who may experience this issue."

More notes on the negative scanning project

Rec.photo.digital experts liked these tools for a negative scanning project:

I've used it for just the purposes you describe, flawlessly.

ACDSee
IMatch at http://www.photools.com
Thumbs+ at http://www.cerious.com

I've also looked at Adobe Photoshop Album which is quite nice, but I fear it's compromised by Adobe's need to lock-in customers. Microsoft is supposed to have a very good image management product, but their lock-in needs are usually nefarious.

Since I'm burning the images to CD (burning twice, so I have redundant storage), I want something that will produce meaningful file names and write metadata to the JPEG EXIF headers. I need the EXIF date to reflect the date of image acquisition, with a staggered delay between each image (so rolls and images sort by date).

I want the file names to follow this sort of convention (probably need to use the renamer): YYYYMMDDDD_1_ROLLID_# where:

YYYYMMDDDD: is approximate date pictures were taken
1: is an roll number for >1 roll/date.
ROLLID: is an identifier for the roll of film if one is assigned by the scanner (may be null)
#: corresponds to negative number within a roll

The person doing the scanning will write a text note on each entry including roll description and comments. A copy of the entire log will be included in each CD.

Each CD will be labeled with a CD identifier of the form: YYYYMMDDDD_# where

YYYYMMDD: date burned
#: CD number burned that day

The text log will contain CD information as well as roll information, will be cumulative, and will be copied to each CD.

I have to do some playing around to get the workflow to be simple but efficient.

Scanning project: scanning negatives

Popular Photography Magazine

1. Store your negatives flat.
A curved negative can result in an out-of-focus scan and a perpetual need to manually refocus your scanner.

2. Clean negatives as well as you would in a darkroom.
It’s much easier to blow air on them before you scan than to clone dust out later. If you’ve got a really dirty or old negative and your scanner driver has Digital ICE (Image Correction & Enhancement), you can run it for cleaning purposes. But beware: it drastically increases your scan time.

3. Quit all other programs.
Ths will free up as much memory as possible for your scanner.

4. Consider what you want from your scan.
Don’t automatically scan at the highest resolution. If you’re only going to view the image on-screen, don’t scan at full resolution; save time and hard-drive space by scanning at 72 dpi.
Save 300 dpi for prints.

5. Check your driver for film presets.
If you can, select your type of film, and get an edge on color accuracy.

6. Make corrections first.
If you can color manage your preview, correct color and brightness/contrast before you scan. And if you’re scanning a batch of images shot under the same conditions, save your correction settings and apply them to all your subsequent scans.

7. Multisample.
Ugly noise occurs randomly, and multisampling beats it by scanning many times and making a composite of the least noisy sections from each sample.

8. Scan it twice.
If you’re having trouble getting the highlights and shadows in one scan, scan for each separately. Then make a composite using layers in an image-editing program.

9. Turn off your scanner when you’re finished!
This will prolong its life and quality.

I'll have more of these. I'm planning to scan 1500 or so negatives. So I'll be posting a few notes like this.

Who would have guessed? A way to configure a LW without the original utility software. Also, a nasty way to disable a LW.
