(old)Puppy Linux Discussion Forum

Hi everyone
I'm doing an online course from the MIT, some web pages have mathematical notation but instead of equations and the like all I see is [Math solving error]. Seamonkey has a MathML addon but it doesn't work, same for Firefox, can't use Opera or Chrome in Wary 5.3 ... I haven't found any .pets or tutorials, has anyone addressed this topic yet? Is there a pupplet that has support for mathematical notation?

hi vicmz

can you post a couple of links so that i can test

This is the site of the course, but you have to register (the course is free of charge, BTW) and view the welcome secuence, there's a part in that sequence called 'immediate feedback' where you have to test the exercise forms.

is this what you mean ? as all the boxes seem to be working on my firefox 13

Yes, that's what I mean. Both Firefox and Seamonkey display [Math solving error] instead of the mathematical notation. At the moment I found one or two sites with some info but nothing seems to work, if Puppy has built in support for this then I should find a way to "let the browsers know."

OK, according to the links provided by L18L, Firefox 15 and newer and Seamonkey 2.12 and newer have support for webfonts, and the MITx page seems to provide webfont support as well. I'll try this, unless I find a tutorial on installing MathML fonts as OpenType instead of TTF. But I'll test later - there's an electrical storm coming, the power is unstable and etc. (Posted from mobile)

Hello classmates
using
firefox 12.0
and
https://addons.mozilla.org/en-US/firefo ... thml-fonts[/b]/
installed

there is no Math Processing Error

OK, I'm starting to worry. I've tried Firefox 14.0.1 and SeaMonkey 2.12.1 both with the mathml extension, the bug remains to me. Time to test on a Puppy other than Wary 5.3

Just in case... L18L, are you using Firefox and Puppy in German with UTF-8 turned on?

Yes, I am in puppy precise 5.3.93
# echo $LANG
de_DE.UTF-8
#

firefox 12.0 (german version downloaded from mozilla some time ago to /mnt/home/opt/)

MathML-fonts 1.1

and now reading the textbook....

OK, then it may be something about OpenType fonts. Running Valiant Ship (Slacko 5.3.3 based pupplet) in English right now, I keep getting the error message. Still searching solutions.

Glad you like the course, by the way. The site says Python 2.7 is required for the programming lessons, is Python included in the devx?

It is in every devx

This time I tried right-clicking on the [Math solving error] message, a menu appeared showing that the course website sets HTML/CSS rendering of MathML fonts as default for my browsers -- I changed it to MathML and got a warning message from the site saying my browser doesn't fully support Mathjax, but giving the chance to try anyway. I clicked OK and voilà ! This is on SeaMonkey 2.12.1 (another case of "not popular, not powerful") without MathML extension, surely works for Firefox or other browsers, too. But MITx courses support Chrome first and Firefox as second choice, so those who plan to give them a go should bear that in mind.

Thank you everyone for your help!
