mailing-list for TeXmacs Users

[Frank <address@hidden>]

Hi, I wonder whether it is convenient to organize non-linear structures when we use TeXmacs as blackboards.

For example, you write out two parallel points of view (like matrix vs vector spaces), and then you need to explain the relation between these two. On the blackboard, probably I write it in two column style and then I add the illustration between these two columns. I don't know how to do it properly in TeXmacs.

Best wishes,

Frank

Thanks Marc! I share your enthusiasm about TeXmacs as a blackboard and I'm glad is working well for you. I myself have some lectures in it and was pleased from the results.

Even having 5-10 min of recording to show as an example would be great!

Hi Max,

I didn't record the session. I will next time, when it will more polished. I plan to ask students to install texmacs on their pc.

I'll let you Know.

Here us the message i sent this morning to all the colleagues teaching science in CPGE.

It's in french

Bonjour.

Je viens d'effectuer mon premier cours en visio, depuis ma campagne avec un pauvre débit ... L'outil testé : wiziq sur notre ent moodle.

Je cherchais un outil institutionnel (pas discord ni zoom) et Via ou BibBlueButton étant saturés, je me suis rabattu sur wiZiq.

Je cherchais surtout de quoi écrire comme sur un tableau sachant que : j'écris comme un médecin et je n'ai pas de tablette ni de stylet. Comme j'utilise TeXmacs (https://www.texmacs.org/tmweb/home/welcome.en.html) pour mes documents d'info et de maths, ça ma semblé naturel de l'utiliser comme tableau blanc. Et ça a vraiment été efficace : on tape comme en latex mais ça s'affiche directement (WYSIWYG ou presque). En partageant l'écran de cette application, les étudiants ont pu suivre les calculs en direct et intervenir par chat. J'avais coupé les micros et ne les ouvrais qu'à la demande.

                        Je vais tester un partage d'écran
                          symétrique : les étudiants pourront aussi
                          installer texmacs et partager leur propre
                          écran lorsque je le demande. Wiziq laisse pas
                          mal de droits aux étudiants mais ils se sont
                          très vite disciplinés et ça n'a pas posé de
                          problème.
                        
                        
                        Pour info, TeXmacs est un logiciel
                          crée par Joris van der Hoeven, qui a montré le
                          O(nlog(n)) pour le produit d'entiers dont
                          certains ont parlé en début d'année. Je trouve
                          texmacs vraiment très facile à utiliser, avec
                          des raccourcis efficaces, des graphiques
                          faciles à créer en direct, un interfaçage de
                          python efficace.
                        
                        
                        Je suis par ailleurs opposé le plus
                          possible à l'utilisation de logiciels autres
                          qu'institutionnels de type discord ou zoom. Si
                          les solutions n'existent pas ou ne sont pas
                          fiables (Via par exemple en saturation), le
                          ministère doit prendre ses responsabilités.Si
                          je dois l'utiliser en dernier recours (et je
                          crains que ça arrive vite :( ), ce ne sera
                          qu'avec l'aval de mon administration.
                        
                        
                        Bon courage à tous.

Dear Marc,

 glad to hear that! It would be possible to see the result? Or in alternative that you record 5-6 min of "fake" lecture to have something which we can use to advertise TeXmacs for such a use?

Thanks!

Hi to all.

I do hope you're all OK.

I just made a two hours "web"class with texmacs as the whiteboard : just great.

For professional reasons, I wanted to use institutional tools : no zoom neither discord. So we chose wiziq in moodle (Bigbluebutton being out of order : too many connexions). And with the chat, the pdfs of my exercises and the screenshare of texmacs it was convincing.

I'll write to the colleagues of my organisation to make some publicity.

Thanks for such a great tool.

Best wishes to all of you.

Dear Max,

I have access to YouTube but I know that in China it is blocked. I think that it is possibly important to advertise TeXmacs in China. I was supposing that if we can offer highly compressed and somehow low resolution version (say, in only several megabytes), then we can upload it on our own server, but I don't know whether it is possible.

Best wishes,

Frank

Dear Max,

Thanks for that. I hope that the tutorial video in question would also be available on the official site (it would also be beneficial to have a possibly low resolution version available on the official website for those who don't have access to YouTube) and announced in the forum, of the existence of which more users will be aware.

 can you suggest a platform which is accessible to you? I suppose youtube is blocked by a firewall?

 I'm not thinking to do it myself right now. :) I was hoping somebody would take up the task. (personally I'm deep into the rabbit hole to port TeXmacs to guile 2+)

I found this very nice video of Vincent:

https://www.youtube.com/watch?v=RFZbt3oZ0ro

Somebody could do a similar video in english, even less fancy, more like Joris' tutorials.

This would be very useful to popularize TeXmacs in this period.

Max

Best wishes,

Dear all,

 in this global virus crisis, me and many of my colleagues mathematicians need to broadcast lectures from home. Typical solution is either use slides or virtual blackboards connected to a tablet. I was wondering if there is an opportunity to advertise TeXmacs as an alternative solution. I myself did once a seminar using TeXmacs "live", that is projecting the TeXMacs window while writing the content as I would have done for a blackboard talk.

If some of you have some time and energy it would be nice to have another small video to show how to use TeXmacs to do online learning.

We could show a simulated lecture where you use the beamer mode as a balckboard to illustrate some theorem and maybe do some drawing, etc... I think some people could be interested in this solution. Handwriting is sometime not so pretty and preparing LaTeX slides time-consuming. So we could have some new users. Especially if we explain simple ways to do things.

I tried to send around your Joris' video where he prepares slides but a more targeted tutorial/presentation would be more interesting.

Vincent? you already have some experience in this. Maybe you could prepare a small example video for french speaking math teachers (either in schoor or at university)?


Best
Max
