Subject: Why Is Cadence Being So Sleazy-Protective With Its Webinar Slides?
Hi, John,
I have a new pet peeve with Cadence. They have regular webinar
presentations that are often useful, but even after registering with them
they don't make the presentation available in a PDF or simple web page.
They use placeware.com to host the webinars, and although that site offers
a web page containing all the slides after a webinar is done, it can't be
saved or printed because each image comes from a java applet.
In Cadence's words:
"We do not post or send out PDF slides for external use. Our
presentations are Cadence Confidential and not meant for printing
by external customers. The reason is that we don't want copies
of our presentations to get into the wrong hands."
That argument seems silly when I can still do a tedious series of screen
captures followed by cropping and Adobe Acrobat to put them all in one file
for saving locally. I am able to quickly make a local copy of webinars
hosted by Yahoo's webevents.broadcast.com. If you click on a small image
you can view the properties of it to get its location, then use a Perl
script like the one below to grab all the larger images:
$location = "http://webevents.broadcast.com/slides/cbc/xx_slide10.jpg";
$location =~ s,/cbc/,/large/,;
$location =~ s/_slide.*jpg$//;
for ($i = 1; $i < 99; ++$i) {
$d = sprintf("%02d", $i);
system("wget ${location}_slide$d.jpg -O slide$d.jpg");
if (-z "slide$d.jpg") {
unlink("slide$d.jpg");
last;
If anyone else knows how to get at Cadence webinar presentations in a more
straightforward way, I'd like to know. Or if you have connections to
encourage the webinar group to post PDFs at SourceLink, please do so.
