Will GIFs Be Free in 2003?
Ark42 asks: "Did the Unisys patent on LZW expire back on Dec 10, 2002? Does that mean we can all write GIF software royalty free now?
From what I can gather, Unisys only lists patent number 4,558,302 for covering LZW, which was filed on Jun 20, 1983 and issued on Dec 10, 1985. According to this site patents filed after Jun 7, 1995 last 20 years from the file date, and patents on or before then last 17 years from the issue date. That means the LZW patent expired on Dec 10, 2002. Am I missing anything?" A deadline of 2003 was given in this earlier Slashdot article. Assuming .GIFs can't follow in the footsteps of Mickey Mouse, will the popular image format now be "web safe"?
What the hell kind of protocol is "fttps"? That's what fttps://yro.slashdot.org/article.pl?sid=03/01/15/1 528253&mode=nested&tid=123 (the last link in the story) specifies... which means the submitter either typed this out by hand (in which case, I feel sorry for them, do they not know about copy/paste?) or deliberately messed it up. (For what it's worth, the same URL with "https" as protocol does work. Although I do think https is a good idea and should be used more often, Slashdot browsing is probably one of the last things I'd worry about encrypting...)
I metamoderate all Redundant and Offtopic moderations as Unfair.
Everyone should switch from GIF to PNG. There is an opensource program called pngcrush (http://pmt.sourceforge.net/pngcrush/) which makes the png's even smaller without sacrificing picture quality. Every png file I've made, after going through the command pngcrush -brute, comes out smaller than gif while looking better and also keeping true colors instead of indexed mode.
