[Bigosinski, Jeremi J]

Thank you kindly Mat, PMario, and Mark S for all your comments. You have given 
me much to think about it.

In response to some of the clarifying questions, here are my justifications for 
pursuing TiddyWiki, and my current requirements:


  *   I like the fact that TW is a one file that can be easily viewed, 
downloaded or make derivative works from. I can see, however, that may cause 
file bloat and when adding images. A 400 mb single file isn't going to work 
when students will be likely using their underpowered smart phones to read the 
text and images. Maybe I can host image in a folder and link to it from TW, but 
that would break the derivative part unless there is a plugin to automagically 
create PDFs, downloadable EPUB, etc ( like there is download option for 
Wikipedia\Wikimedia). I just don't want to constantly maintain and update a 
separate file for that purpose. An acceptable compromise might by a chapter by 
chapter download versus the whole thing. Or maybe I shouldn't care and just 
leave it to the end-user to figure it out. Seems very rude though IMHO. This 
isn't a critical feature for me, but it is part of the OER ethos.

  *   To me, a linear process is going from Step 1, Step 2, and likewise, 
reading from Chapter 1 to Chapter 2, and so on. You are correct that books, per 
se, are not very linear in their creation, but I was alluding to the process in 
which they are read or understood. I don't want to confuse students by making 
it too easy to skip around and miss critical concepts by not going in a 
specific order, which can happen with "Research Wormholes" on Wikipedia where 
all you wanted to find out was about Topic A but then you get off-track by 
reading Topic B,C,D,E, etc.

  *   I'm drawn to FLIF as a modern alternative to animated GIFs., which 
depending on size and resolution can result in massive file sizes. I do not 
think that JPEG XL can serve animated content, if only be going by the lack of 
doing so for JPEG and JPEG2000. Considering device issues and internet 
connection speeds, GIFs really aren't going to cut it. I could fall back on 
APNGs, but that format doesn't have much browser support either but it may end 
up being the necessary compromise if I can't get FLIF to work correctly. The 
only player left in this small format field (AFAIK) is Google's WebP format, 
but cursory research reveals double the file size of an equivalent animated 
GIF. http://littlesvr.ca/apng/gif_apng_webp3.html You might point out to just 
use videos, but people read faster than listening to the spoken word or 
watching a video. I want to be able to serve short animations of 5-30 seconds 
of content at a time, as necessary, fronted and backed by the appropriate text 
explanation. I'm not a back-end developer so by suggesting to figure out a 
widget to make FLIF work with TW is probably the answer - not going to happen. 
=)

  *   I just saw the post about a TiddlyWiki Textbook. That's really cool and 
will try attempt to contribute only to see if that's going to work for my 
needs. In the meantime, I guess it's time for some rigorous testing. Aside from 
TiddlyWiki, I've been looking at DocuWiki and Wiki.js. I might have an open 
source webhost lined up too (where server space and bandwidth is limited - 
necessitating image compression algorithms), we'll see.


Best wishes,
Jeremi

TW plays well with JS, if you know how to do it. It is more advanced as adding 
a script to a static page. TW is highly interactive and the "visual elements" 
can be redrawn anytime. ... So you probably will need a new widget, that can 
deal with your image format.

FLIF will probably _never_ be supported by major browsers, since it is 
superseded by JPEG 
XL

[tw5] TiddlyWiki for Books (Newbie Questions)

[Bigosinski, Jeremi J]

Hello,
I've been looking into using TiddlyWiki to create an online instructional 
manual. I'm not clear on three things and am wondering if someone could help me:

1) When the TW is published to the web, can anyone edit it and change it (a big 
problem for obvious reasons). I don't mind if they want to change their "view" 
or navigation, but not the content. I saw this article: 
http://80.56.108.132/TW5/TW5_readonly.html that makes the TW read-only. Is 
there an easier way to lock the file with User Access Control, or more blunt 
like with CHMOD or HTACCESS or would that break TW? For example, I write up the 
master file on TiddlyDesktop and then upload it to the web and lock it...

2) The tagline for TW is a non-linear personal notebook. I like how the 
tiddlers operate versus other wikis and the ability to hide the "cards" 
(tiddlers). But, as I want to use TW in a VERY linear fashion, am I making more 
work for myself than by just using other software tools?

3) How well does TW play with Javascript? I want to implement an open source 
image compression algorithm that doesn't yet have major browser support. The 
only way to use it at the moment is to wrap the image in a javascript script. 
For those interested, I want to use this: https://flif.info/

Thank you,
Jeremi
