In a (very) quick note on his blog today Stoyan Stefanov points out that a presentation of his posted over on Slideshare made the front page Featured section (with over 2600 views too!).

Not bad. Especially having in mind that this is the second time around. [...] Slideshare is a great service nevertheless, just like on youtube, you can spend hours browsing people's presentation slides.

The presentation was originally given at the PHP Quebec conference this year (2008).

Hasin Hayder shares a method for "hacking" the Slideshare.net service to be able to download whatever slideshow you'd like:

I just spent some time today analyzing the HTTP requests made by the player available in slideshare using LiveHTTPHeader extension and found a way to download any presentation you want! There are many slides available in slideshare where you see that "Download not available" - But as long you have some knowledge on web-scrapping, that doesn’t matter at all.

He includes the code that you can point at a slideshow's URL and let run. It works through each of the pages of the presentation and pulls out the URL of it and echoes it back out.
