Help! I'm trying to install Yosemite on my computer and it keeps telling me that that it can't install on my hard drive. I can't figure out why. First it said it was only used for backups. So I unlocked it and gave myself read and write permission. Still won't let me.

This was my sister's computer before mine and she's not a Mac person. I can't figure out if she did something that needs to be undone before I can do the update.

I'm not even sure anymore how to trouble shoot this stuff. It's like the hard drive is not the hard drive but an auxiliary drive.

For music hardware geeks:

The Tefifon

Laughing Squid sez:

Tefifon, A Little Known Cartridge-Based German Music Player From the 1950s

YouTube gadget channel Techmoan takes a look at the Tefifon, a short-lived German music player from the 1950s that uses a cartridges with plastic tape that have grooves similar to those on a vinyl record. The technology, which was invented in the 1930s, was completely discontinued by 1965, losing the format war to the much more popular phonograph.

quester, did you get it installed?

DCJ - No. I mucked around with trying to get control of the hard drive and screwed everything up. I can't find the Lion disk and my sister doesn't think she still has it.

I did find a backup and restored everything but it still thinks the hard drive of the computer is only for backups and won't let me install it.

Even when I signed on to the computer and Apple as my sister, still won't let me.

She;s not a Mac person, she teaches programing and is wholly PC. She got this Mac to see if she could learn how to program but got so frustrated she was ready to pitch it when I told her my Mac had died. So, I don't know what she did or how to undo it.

I tried to reload Lion via the internet, but it wouldn't work…not available. So I'm back to the way things were.

I have my own log on, but the computer still thinks it belongs to my sister.

Ok, I'll message you in the book of face.

Wordpress.org question. I'm writing a post that includes the string "x10" (I'm describing a box set of 10" vinyl records as 5x10"). Wordpress sees the "x10", decides that it's unicode(?) and converts it to a character that appears as question marks. I just want to to display the original 5x10". If I use a capital X, it works fine. Is there a filter or somesuch to prevent these substitutions?

On edit: Looks like it only does the conversion if there's a digit before the x10. So, 1x10 converts to 1�10, 2x10 converts to 2�10, etc.

Jon, I don't know wordpress, but does it happen if you use the html entity for times (×), i.e., 5×10"?

edit - As in I had to use the entity for ampersand to get the code for entity for times to show up properly.

Yes, the issue is with displaying a times symbol. Apparently Wordpress substitutes a times symbol when you type a lowercase x between two numbers. It does this with various characters, most notably substituting in smartquotes for straight ones. See [link]

Now I just need to figure out how to add a filter that turns off the times piece.

I actually wouldn't mind the substitution if it displayed correctly! No idea why it isn't. It's supposed to be using UTF8.

Heh. Someone made a plugin that does what I need: [link]

I still don't understand why the × isn't displaying correctly, but whatevs.

Ok Folks, even though I was laid off doesn't mean I can't want something.

Do any of you have old Nikon camera lenses with F or AF mount laying around and want to find a good home?

For services rendered, I have been given a Nikon DSLR body, but all of my lenses are 30 years old and Pentax (working on an adapter) so anything might be helpful, let me know.
