This article is full of egregious errors.
There are also very significant missing pieces. For example, it was possible to buy an LZW license from Unisys to legally make GIFs; a key reason for the slowness of GIF’s replacement with PNG was that PNG was still unsupported by some major browser (IE?) until shortly before the LZW patent expired; LZW was and is a major presence in hardware data compressors; and God only knows what else.
These errors are all within a couple of paragraphs of each other. Finding such a high density of errors in one part of the article makes me wonder if the other parts of the article were equally full of errors that I simply wasn’t competent to notice.
We should make a Wiki article on this topic so we can get it right.
Perhaps you should point these errors out in the article’s discussion section instead; posting it here won’t change anything.
Interesting! That means there’s a major factual error in my own critique: this is a Wiki article, already, and it’s even under a CC BY-NC-SA license. That might explain what seemed to me like very uneven quality in the article, and also means I can do more than just point errors out: I can fix them! At least, I can if they give me an account so I can edit.
A day later, I have their email-address-confirming email, but they haven’t created my account yet.
Updated: account created; now I’m going to try correcting one of the errors above and see if it sticks. I’m trying the first one. I’m not that optimistic — the page was apparently written in 2011 by Rihamichael as his/her semester project at SJSU, and has seen only minor updates since. So basically the Wiki is dead.
