[PD] dead links [was] Re: [PD-announce] pd 0.46-0test1 released

[Julian Brooks]

On the subject of FUDI -

'http://wiki.puredata.info/en/FUDI'

Isn't up anymore (it's the solitary wikipedia external link amongst other
things).

Is there another copy/more thorough FUDI spec list somewhere?


Also, from -

"Pd Documentation chapter 4: writing Pd objects in C


Iohannes Zmoelnig has written an excellent guide to writing externs at
http://iem.kug.ac.at/pd/externals-HOWTO/ .

A paper by Theo Stojanov on the subject is at:
http://www.music.mcgill.ca/~theo/html/audio/pd_externs.pdf ."

Are currently dead links too.

IOhannes' is available here:

'iem.at/pd/externals-HOWTO/pd-externals-HOWTO.pdf'

Theo's paper is more elusive.


Regards,

Julian
