A handy tutorial on passwords

How To Spot A Psychopath :: Nonsense passwords :: October :: 2006. He likes nonsense words, and uses KeePass to measure entropy. 70 bits sounds like a useful metric.

The OS X keychain utility has a similar built in password generator and metric. GRC has a web accessible random string generator. I'd like to see GRC add a 4th option limited to characters that are clearly distinguishable when printed, thus avoiding i and j, 0 and O, 1 and 7. (Means you need a longer string to meet entropy requirements.)

Internet Acronym Server

This service dates to 1988, so it is of the age of Archie and Veronica and many other forgotten services of the pre-web Net.

It's rather nice to know that it's still running. Note the domain name: Internet Acronym Server.

MacBook random shutdown: balky heat sink sensor

I'd read many theories about the random shutdown problem with MacBooks. None of them turned out to be right. Apple had a hard time sorting it out -- they were replacing motherboards and machines for a while. The problem, apparently, was in a heat sink sensor:

PC World's Techlog MacBook Shutdowns: Case (Finally) Closed?

... Last Monday: I get a phone call; my system is ready for pickup. The courteous Genius who gives it back to me provides more details on the defect: Some MacBooks have a heat sink sensor that malfunctions, thinks the system is overheating when it isn't, and shuts down the machine thinking it's preventing potential damage.

Modern laptops are insanely complex. Apple needs to invest more in self-diagnosing hardware.

iSync users: avoid Motorola phones?

Reading this and a related iSync article I come away with the impression that sync is unreliable with Motorola phones, but I'm very intolerant of sync errors.

I think Motorola sells the most phones in the US...

Google product search without the parasites

Give me back my GOOGLE™ is a Google front-end that's designed to screen out the morass of software generated and fraudulent 'review' sites that now infest results of a product review search. The author uses a basic blacklist approach. Yahoo! had a similar product that allowed one to bias search away from vendor sites.

I hope Google is figuring out how to get rid of these lice, but in the meantime it's nice to see prototypes for future solutions. In the meanwhile I use Amazon for review information -- if you sort for lowest ratings first then read up you get excellent product information. If you're a hardware geek, the newegg.com reviews are quite good as well. Then there's Ars Technical, Tom's Hardware, limiting search to bloglines subscriptions, etc.

So it is possible to find good product reviews, but Google isn't yet part of the solution.

Force iPod to mount in manual mode

A good way to mount an iPod without overwriting it with an unwanted sync:

...hold down Command and Option when you first connect the iPod to mount it in manual mode...

More techniques for reviving dead hard disks: swap circuits

I thought I'd hear 'em all (my favorite is chilling a drive in the fridge), but this is new to me. I suspect drive recovery services have known this forever ...

MacInTouch: timely news and tips about the Apple Macintosh

[Ken Spencer] My daughter had a lot of photographs, some of which were not backed up, stored on a LaCie D2. She plugged it in one day, saw smoke and was out of business... when the board in the drive enclosure went, it took out the board in the Hard Drive! It was a Maxtor. In desperation, I bought an identical Maxtor, and discovered that the controller board connects to the drive with spring loaded contacts under the board. Took out 5 screws, took the old board off the Maxtor, exchanged it with the board from the new drive, and was able to recover everything! She bought a WiebeTech drive enclosure, and they were very helpful in helping her try to solve her problem.

[Robert Burke] Regarding Ken Spencer's solution to the bad hard drive logic board, I too have done this. One of the users I support had his hard drive die in a newly purchased refurb PowerMac G5 some time ago. On a hunch, I swapped the board with a like unit from another PowerMac we had. The drive worked as normal and I was able to get all his data off so he could take it in for repair. Note, though, that I'd only do this with the exact same model of hard drive, and same version of board if possible...
