After arriving at work I made some break-throughs on the part of the DEFLATE algorithm I wasn't understand. Prior to this I had almost gotten to the point of emailing the creators of a couple docs I was reading to plead for better examples/explanations on some parts. When I've got this under my belt I'll have a document for other people like me to read and, hopefully, gain a better and more thorough understanding of this thing. Specifically I was having difficulty generating the correct literal/length Huffman tree from the code lengths alone. I didn't quite understand how the code lengths were sufficient to generate an entire tree and it took me a while for it to "hit me" and things to fall into place.
I really need to write this all down in a document before I forget it and have to start all over next week.
Thursday (the 14th) I was on my second day of Jury Duty so I missed the ol' S.B. That's two weeks of missing my bi-weekly hobby time and that's not good. I think I made some of it up today, however, in working on a couple of List Server bugs.
Gmail appears to remove HTML comments and another WebMail program munges the HTML horribly beyond recognition -- even using flattened HTML for the plain text version when a plain text part exists! Anyway, all of this added up to the footer notice not being recognized and removed (I was using HTML comments in the HTML part and a specific text in the plain part).
I deliberated a great deal on the fix to this. Something that would not cater to the flaws or quirks of any particular software. What I eventually came up with was a simple character "key id" which precedes and follows the notice:
It looks kinda like a face, don't you think? Anyway, email clients leave these characters intact and next to each other. Not only do I find these, but I like for the word "unsubscribe" in between them as further verification.
Additionally, I simplified the notice to a single line in the HTML version and two lines in the plain text one. The blob was eye catching, but quite distracting.
Oh yeah, I also added the beginnings of the ability to "censor" certain text. It sounds bad, but really it just means to remove or hide something. In my case, I added a pattern to get rid of AVG's scan notices which Outlook Express dumbly puts into replies and forwards (even though it's a separate MIME part).
Another Outlook Express irritation is that it doesn't hold onto attachments when forwarding or replying, it drops them. You have to re-attach them. Ugh ... I wonder if it's reading the list server emails incorrectly or I'm putting something there that's confusing it (a very real possibility). I will have to look into that.
