Mathjax is indeed very good looking and truly cross browser/platform !
There is however a few small drawbacks: you will need >75mb of fonts installed on your wims server (lots of overhead on small systems) or you must make use of some global « mathjax » fontservers for supplying runtime the fonts needed, Which implies your exercises being 100% dependant on an other server not under your control.
And you may expect serious trouble when using Mathjax for drag and drop exercises within wims…
But it's all a matter of time for the other browsers to support MsthML natively
(eg HTML5)
see: https://vismor.com/documents/site_implementation/viewing_mathematics/S6.php
Chrome does not currently provide native rendering of MathML. Without
supplemental support, mathematical content is often indecipherable.
Chrome (like Safari) is based on the WebKit open source project. Hence,
Chrome — with regard to MathML rendering — is usually similar to Safari. Since Apple released Safari 5.1 with WebKit’s MathML implementation enabled, it is reasonable to assume Chrome will acquire mathML support in the not too distant future. However,
Google has not publicly announced its intentions in this matter. As of Chrome beta release 16.0.912.63, MathML support has not been enabled in Chrome
As an aside, the current iOS version of Chrome (formally known as the Google app) supports MathML. The system libraries used by applications on iOS 5 to implement browsing shipped with MathML browser support enabled; hence, iOS versions of Chrome provide MathML support.
See Section 5.1 for further discussion of MathML support in iOS 5.

Dear Yves, you should use left right this forces stretchy parenthesis in latex kind regards,

Il y a à mon avis un problème avec left( qui donne des petits carrés.
En plus l' équation est coupée en 2 . Pourquoi???
Sinon c est très beau et très fin. Encore du beau travail. Bravo à vous.

Tu donnes un lien sur un serveur où il y a des images. Peux-tu aussi donner le nom du block, sinon c'est difficile de retrouver (dans la barre url : block=xxxx). Sinon il est possible que l'équation ait été coupée pour ne pas faire une image trop grande … ce qui n'a plus de sens maintenant.

In my view if you see a message like:« WIMS panick! Unable to bring up wimslogd. Permission denied «in your browser (pointing at http://yourserver/wims/wims.cgi?), there is nothing wrong with apache.(apache is showing the error-message of wims)Just install wims as 'user wims'.Execute as root the script « ./bin/setwrapexec »The panick is most likely caused by wrong permissions.If you have installed wims on a separate partition or hard drive…make sure your « /etc/fstab » is correct. (eg shell-scripts and other programs may be executed)KInd regards,Joke EversHi,
I am using « ssh » (secure shell) to maintain wims-servers from the internet/intranet.
This because I'm not to keen on the html-interface via « WIMS gestion du site en ligne » …
To use « ssh » , port 22 should be open on the firewall,
you should have an account on the server;
and you should have « sudo » access to the « wims » account on the server
(e.g. the command « sudo su – wims » will make you « user wims » )
This will give you a non-graphic interface (a terminal & shell) to interact with « wims ».
A very potent filemanager in a terminal is « mc » (midnight commander).
Ofcourse if your bandwidth is high enough , you could start a full blown graphical session ;e.g. with all kinds of windows and buttons etc to maintain the home directory of « wims »
(but I'm not sure if I understand the problem…)
kind regards,

I think « wims » will convert all numbers to E notation if the number > 10^8
And octave will convert any decimal to E…
1.23 -> 1.23e+00
And any large number > 10^8
100000000 -> 100000000
1000000000 -> 1.0e+09
12300000000000000000000000 -> 1.23e+25
I dont know of an easy way to convert « small » numbers into E
100 -> 1e+02 ?
kind regards,

Hi,
I think the best way is to install a wims-server on your intranet.
That way you have:
– total control over the system and the system logfiles
– high bandwidth
– high availability
– raw ip-adresses and MAC numbers are available if you are « root » on such system
– monitoring/tracing of fraude is easy
– use automatic updates for modulesThere are a two possibilities, depending on the amount of support/cooperation you can get from you local IT-managers (…)
1) Intranet server is not usable from the internet.
– use a public/free wims-mirror for homework
– manually synchronise with your intranet server
– automatically synchronise with your intranet server (raw connection)2) Intrantet server is usable from the intranet
– the best solution
– install wims on your internet gateway or use a separate computer in DMZ (…)
– no need for mirroring.
– internet adress is used for just homework ; no high bandwidth needed.
– schoolwork/wims-lessons on intranet : high bandwidth neededOn our school we use the Leiden mirror primarily for homework and sometimes for schoolwork.
The « scores / total studytime / effort » on the internet server are used indicative: but they can influence a « real score ».We use an intranet server for the « wims-exams with real scores/grades ».
The intranet server is not reachable from the internet…we must operate in a clumsy Microsoft based network
The school server is automatically synchronized at 7.00 every day ( Leiden mirror –> intranet ) for user accounts and passwords.
Worksheets and exams are also copied and are set to « invisible and inactive » on our school server.
In that way a teacher can activate the « exam for a real score » at the start of the lesson. No cheating is possible.
The automatical update is not a wims feature … we use a « cronscript » on the Leiden mirror for this.
A « cronscript » on the school server uses Wget to fetch the daily update and do the unpacking and some other admin stuff.kind regards,
Joke
