Looks like the creator announced a plan to stop caring for the dictionary in January of 2012. FASTAR apparently agreed to take it over, but if they did it is locked behind their authentication system.

Someone should scrape and preserve.

its dying because its not a wiki

there is tons of stuff on b+trees online but nothing there. Could easily remedy that with a small amount of work

I made a mirror of the website.

This is a great resource, but may need a bit of an update. It's missing Wavelet Trees for example.

Neither detailed nor comprehensive. Most of these are just random pieces of jargon with 1-sentence explanations. They also forgot to add a bunch of really fundamental data structures too. Where are range trees? They are in like every database in existence.

I wish there were a ready offline/download version of this one.

wget -mk -np -w 10 http://xlinux.nist.gov/dads/

You can use http://www.httrack.com/ to build a local version of the site for your own use.

Thanks for the idea (and karanbhangui). I'm a little uncomfortable scraping a government website in these litigious times, so I was hoping NIST had a big PDF or something. :)

Haha I scrape my banks website everyday 24/7. They dont care / wont notice.

scrape bank's website? What for? Just download your bank statement periodically :)

Paranoid much?

On behalf of FASTAR: we've updated our main page (fastar.org) to include information about the imminent migration of DADS to FASTAR.org. The site will remain open for public access.

That's an overwhelming list. Well worth a bookmark, though.
