Somehow I managed to break the CDF plugin, and I need it.

Does anyone know how to re-install it on OS X?

Removing /Library/Internet Plug-Ins/Mathematica.plugin does not actually remove the plugin. I still get the "Loading CDF" and the spinner. The problem is that it never actually loads.

@Szabolcs Have you redownloaded the plugin and tried to install that? Sometimes I also had to restart at least the browser

@Matariki Yes.

No change.

That's why I'm looking for a way to remove it before re-installing.

I thought that removing Mathematica.plugin would remove it, but it did not.

I see

I'll try to find out whats gets installed where. Do you still have the install log?

@Matariki I doubt it, but where should Ilook for it? You're also on OS X?

@Szabolcs yes OSX 10.8.2

You mean the log from installing the "extras", right?

Is there one? I'll try to reinstall on my machine and hope that I can trace the new files using Filebuddy

I don't see anything in the console. I guess I should look in the extras installer package to try to find out what it does.

Good idea

I'm going to log out for a second, be right back

@Szabolcs Tracing didn't work the list of files is incomplete. Have you tried another browser?

@Matariki It was broken in three different browsers. But after rebooting and reinstalling after reboot, it works. I don't know why, but I'm happy.

Maybe the browser hasn't quit properly when I reinstalled last time.

@Szabolcs Cool. I was starting to look into the installer with Pacifist but as you got it working I'll stop

BTW the content of the installer gets installed in only 3 directories and the plugin part goes only into the directory you have mentioned above.

@0x4A4D This question has been edited and seems valid to me now. Since you have closed it, I cannot vote to reopen. Would you consider reopening it?

It's deleted.

@Szabolcs That's what I meant. /.{"closed"->"deleted", "reopen"->"undelete"}

The code is correct now, and the question about why Solve can't find a solution in reasonable time is valid

I never used embedded CDF before, so I never had to care about what is not allowed ... is there a way to find out why it won't display, and why I get the "unsafe dynamic content" warning in Mathematica? There should be nothing unsafe (no file operations, no input text boxes, etc.), so I'm a bit confused

@Szabolcs I don't know of any way to display why you specifically get that message but it could be that you are starting the cdf from an untrusted directory which will trigger the display of the message. have a look into the NotebookSecurity tutorial

It looks like it happened because I saved it using Export and not CDFDeploy. WIth CDFDeploy it works fine, but I can't get it to display in wordpress without issues (the wordpress cdf plugin breaks things in the latest wordpress and the <embed> method leads to a lot of flickering), so I gave up

@SjoerdC.deVries Since there's this, is there any reason why the other one should be restored?

@0x4A4D I hadn't seen he posted another one. Forget about it, sorry.

hi guys

This guy is rather willfully obtuse, I think...

I've a funny feeling that the reason why we're getting most of these MatrixForm[]-related questions is due to the line "MatrixForm acts as a "wrapper", which affects printing, but not evaluation. " in the docs...

Then to their shock, they see that Transpose[MatrixForm[{{1, 2}, {3, 4}}]] doesn't behave in the manner they thought it would.

@0x4A4D I think that newcomer don't read the docs this carefully. They see that with MatrixForm looks like a matrix and they are happy. I never saw someone who thought it might be the wrapper thing which breaks the code.

@halirutan That's part of the problem (which we all know is incurable ;P ), but maybe something more explicit in the docs is needed. Back when it was new, I understood that it was an "output-only" function, but I think people have gotten spoiled these days with the fancy formatting...

(BTW @halirutan, how did you reply to that e-mail?)

@0x4A4D Yes, I agree that these days many people forget that Mathematica is a programming language and all the fancy formatting can lead to very unexpected behavior in inexperienced hands. Unfortunately, it's mostly the newcomers who love the highly formatted code.

@0x4A4D And yes, it would maybe help if it was more explicit that this should only be used as output formatting function.

@0x4A4D You mean the mail from the 2d-code.co.uk editor?

@halirutan Yes, that.

@0x4A4D The article is almost finished.

Something new for your CV... >:)

I agreed to write something non-mathematical for the market people.

@0x4A4D Even better: In the example QR codes I show, I can encode the URL to Mathematica.SE, to my institute, etc..

This site seems to have a lot of readers so we maybe get some more publicity. It's hopefully a win-win situation for everyone.

@halirutan I'd be sad for you if you didn't exploit the opportunity. ;)

@0x4A4D Don't worry, I will.
