New math rendering engine

I've been restricting my tablet browser here for a few days with JavaScript only enabled for specific sites using the Kindle Fire Silk Browser.

Initially I added:
www.mersenneforum.org

The new math here and forum activities seemed to work fine with that single permission.

After reading a post by Ernst about needing mathjax site permissions I added
mathjax.org
cdn.mathjax.org
www.mathjax.org

In my case it mysteriously didn't seem to need those mathjax sites enabled but I entered them anyway.
I know the my overall JavaScript permission is working because in the case of YouTube I added the following three lines one at a time before YouTube worked for me:
youtube.com
m.youtube.com
www.youtube.com

I thought I had full functionality but just now found that the forum server hosted JavaScript from Mikes link that I quoted above also needed me to add:
mersenneforum.org. -- without any "www." for the forum server hosted JavaScript pages to work.

The math is very beautiful on my 323 ppi tablet.

No shit - but this thread is specifically about the new mathjax rendering engine, not the legacy tex-tags one - for the old one I need to turn on image rendering, so in that regard mathjax is actually better for me. Am I speaking !$&^#* Greek that that was not clear that I was referring to the new system, subject of this thread?

No - compare the toggle sequences:

OLD: 'ctrl-,' to bring up user options, click image checkbox, 'ctrl-r' to reload page. Or for a single image, right-click on the image-stub and 'view image'.

NEW: 'ctrl-l' to put cursor into URL field, start typing 'about...', hope for an auto-completion. Once that page loads, type the leftmost letters of the image-enablement sekrit string until you find the one (of many) you need. Right-click on the entry, select 'Modify', then edit the value to enable, 'OK', then reload the page in question. When you want to revert to no-images mode, you must repeat the whole procedure.

I am surprised all those new fancy browsers don't support site specific image rendering. Maybe everyone here should consider upgrading to FF 3.6 like I have, because that supports a simple option of "Load images automatically" and an "Exception" button beside it. So I can untick the "Load images automatically" and then choose "Exceptions" to add particular sites I want to allow.

Your plight makes much more sense now.

It is very surprising there is no toggle or site-specific rules for images. It wouldn't be that hard to add. They have stuff like that for everything else.

a few things that may stop some of the carnage this thing could of caused is that many of the tags that are used here interfere with it so that only text area's that are unimpeded by something else like code tags are likely to produce this mangled post scenario. also things inside code tags are not affected so only code using two outside a code box might have a chance to be affected. lists with list tags are not affected etc:

examples:

$ affected $

$

not affected

$

$ affected $

$

not affected

\$

$

1. not affected

$

1. $affected$

$\ not affected \$

anyways I'm being too obvious with my examples I bet.

my point is that the statements s that will need fixing are s that aren't in S, where S is are the statements not incompatible with TeX.

for those of you who want to keep score of things the URL's I've sent Xyzzy lately to "fix" things:

if I've kept everything updated I think there's 135 so far that I've found. but I've also checked a good 900+ posts I think

[science_man_88]

after checking Mystery Economic Theatre 2013 page by page ( 29 pages I think) and checking if I had them I've added another 34 roughly. edit:( okay only about 16 of those are from that one thread), the good part is that the fixing process if it find quoted ones will grow quite a bit so one post with 2 quoted would fix all three and if those two quote 2 etc.

[science_man_88]

just thought I'd update people I found a few more but more interestingly I found a quicker way to look for them that I totally forgot about the printer friendly versions of threads still have the dollar signs so I can search the printer friendly versions of threads ( at up to 97 posts per page) and find all the ones that may cause problems ( oddly a few have been found that seem not to have an issue when at last check they should so I'd still need to double check, but this method allowed me to check the whole of the PARI commands thread quite quickly because it took what was over 230 pages long at the forum default down to 27 pages to use my browsers find function on.)

[science_man_88]

sorry for spamming this thread , my condolences to the Hardware forum Mods in the last couple of hours alone I've used a few ways to find mangled posts and I found over 70 of them that I've already sent off to Xyzzy so I hope you don't get overworked ( I'll have to put them in my file later).

I'm using an older version (22.0) of FF on this here Mac, don't feel like upgrading because all versions after that have the 'image display' checkbox removed from the user options menu. (There's a 3rd-party plugin now to again restore control over that bandwidth-hoggishness (not loading images is a big speedup in a slow shared-WiFi setting), but why should I install extra crap just to regain control over a feature Mozilla should never have removed from User Options to begin with?)

Does anyone else experience this 'flatlining' behavior?

<aol>Me too!!!</aol>

To some extent, anyway. Some, but only some, examples show the behaviour you describe. I'm running

About Opera
Version information
Version

it would appear.

Don't know if subsequent personalization has changed the behaviour to what I see.

Do you see the same phenomenon at http://www.rechenkraft.net/aliquot/intro-analysis.html ?
