I wanted to edit the index.html file that sits in the ~/Sites folder. If you double-click this file, Explorer opens. So I picked it up and dropped it on my jEdit icon in DragThing. Poof - the file vanished! jEdit is a Java-based text editor, not some kind of auto-deleter, so it looked like there was a bit of a problem. A quick look showed it wasn't in the trash, and I couldn't use Sherlock to find the file, since I have about 2,500 index.html's on my machine ... so it had basically vanished into thin air.
As an experiment, I duplicated a text document, renamed it to "XXXYYYZZZ" and dropped that onto jEdit. Same results - poof, file's gone. But this time I launched Sherlock, and searched for the file. No sign of it on any disk. So once more, I went back to the finder, duplicated a text file, and named it the same thing as before. Dragged it onto jEdit, but this time, I got a message about there already being a file with that name in the location, and did I want to rename the file?
This was the enlightenment I needed. I went to the finder, right-clicked on the jEdit app, and chose Show Package Contents. There, sitting inside the jEdit application bundle, were all my test files, and the missing index.html file! Somehow, dragging and dropping the document on jEdit moved it into the app bundle, instead of launching jEdit.
I tested this with a couple other apps, and couldn't repeat the behavior. But I can repeat it consistently with jEdit. So if you use DragThing, and you seem to have dropped a file and had it vanish, check the bundle for the application you dropped it onto -- it may very well be there!
One of the best new features in OS X is the ability to batch-convert application links for various documents. Before finding this, I had inadvertently started up Classic simply by clicking on a .jpg file that could have been viewed in Preview instead. To make the files open a different application, shift-click to select as many of the same document type as you want (for example, 100 .jpg files), then choose Show Info from the File menu in the Finder. Select Application in the pop-up menu and you will be able to select any application you wish to open the files. Once you've made your choice, the batch-conversion is nearly instantaneous.
Open TextEdit, create a new document, and then drag in an application ("Clock", for example) from the Finder. You'll see a clock icon appear in your document. If you save the document, it will be in "rtfd" format, which the Finder tells me is "RTF with attachments." If you look at the size of the file, you'll see that, in fact, the entire app has been saved with the document! Now open the file you just saved. Double-click on the application icon (the clock, in this example). The application launches right from TextEdit!
I have no idea as to how this might be useful; maybe it's a standard data format (but I've never heard of embedding an application in an RTF document?). There's nothing in Apple's help about this 'feature', so this is about all I know. Anyone care to shed any more light on the subject?
If you ever want to send email through one POP account, but with different sender info, there's a trick to doing so with mail.app. An example of this would be Yahoo! services, which allow one to have several public "personalities", each of which dump email to just one yahoo.com email address. In order to respond as the proper personality, you need to pick a different "from" address, even though you have only one POP account.
In mail.app, in the Account edit screen, you can enter multiple email addresses on the 'Email Address:' line. Separate each with a comma, and then save your changes. When you compose a new email from that account, you'll see a little pop-up for selecting which address you would like to use as the sender of the email. Very slick trick, and easier than creating an entirely new account.
You can't change the physical name, though - only the email address. If you need a different physical name, you'll have to set up different accounts.
Apple's mail.app stores most of the text strings it uses for creating replies, displaying dialogs, and composing new messages in an easy-to-edit text file. If you haven't relocated your mail.app, you can find the text file here:
When I tried to edit this in the terminal, all I got was gibberish - it's a Unicode text file. Opening and saving it in the GUI works fine; you just have to use a control-click on mail.app to "Show Package Contents" in a new Finder window, and specify which application to open it with (I used TextEdit).
Amazingly enough, the text file is even commented, explaining what each line does. You'll have to do some work to change the default reply string ("On March 23, robg wrote..."), as the date format strings are all variables - I imagine they match those used by the system date command, which you can view in the man pages:
Have fun customizing, but you should probably make a backup copy of the unmodified file first -- just in case! Any changes made take effect on the next launch of mail.app.
Panther update: As noted in the comment below, you now need to edit /System -> Library -> Framework -> Message.framework -> Resources -> English.lproj -> Message.strings. In addition, you'll have to reboot after making the change to see it take effect.
To synchronise my Visor, I add "Serial Port Monitor" to my start-up items. It can be found inside the Palm folder of the Palm desk-top software. This automatically starts Classic.
An icon is left in the dock with the Hotsync logo. This is normally a faceless background application under OS 9- and does nothing when clicked. However, when the Hotsync button on the cradle is pressed, it will happily sync your Visor.
I have found that it's best not to put the Hotsync Manager in the background during the synchronisation process as it can sometimes hang the Classic environment.
The MacNN boards are always interesting, to say the least. This thread discusses using your OS X box, in conjunction with cron and an Applescript or a shell script, to launch iTunes and play an MP3 at a certain hour each day.
I'm all for the integration of technology, but I think I'll stick to the old clock radio for early-morning wakeup duties! Still, it's an interesting article on what you can do with OS X...
Although you can't command+C copy from the "Address" line in IE 5.1 (we all hope it's a bug, not a feature!), you can drag the little '@' symbol to a text window and the url will paste where you drop it at. This also works in text fields on pages, which also don't like to be copied in IE 5.1 - just highlight and drag the text where you want it to go.
Some will say that the best workaround for this bug is OmniWeb 4.0 ;-).
This goes in the "Hmm, that's interesting" category ... or the "Check the prefs, bozo!" column, based on the comment below ;-).
I was taking a look at Apple's "Mac OS X: An Introduction for Support Providers" (a very good overview of OS X, by the way), and I was trying to browse the file with the scroll wheel on my Intellimouse. It seemed I could scroll down, but then it would get stuck. I could scroll up again, but not down. Similarly, at the top of the page, I couldn't scroll up any longer, but I could scroll down.
It took me a couple tries to figure it out. In the Preview app, the scroll wheel only scrolls on the current page. To move to the next or previous pages, you have to hit the next/prev arrows at the bottom of the screen.
I'm not sure if this is a bug or a feature! I like the way you aren't suddenly jolted to a new screen if you scroll off the bottom, but it's a pain having to hit the arrow button for each page.
