New wiki site

[Waldek Hebisch]

I have bought domain fricas-project.org and I am configuring new
server. You can see static version of wiki at
wiki.fricas-project.org.

ATM content is the same as fricas-wiki.math.uni.wroc.pl, but
fricas-wiki.math.uni.wroc.pl probably will be shut down in
the future.

Due to suggestion from Ralf Hemmecke I also bought shorter
fricas.org. Also, I got a certificate so you can access
wiki both via http:

http://wiki.fricas.org

and https:

https://wiki.fricas.org

The new wiki site at wiki.fricas.org now allow again running FriCAS.
The site runs in new virtual machine with updated operating
system. Compared to old wiki there are some limitations: old
wiki allowed running Reduce and in the past Maxima and possibly
Sage and Sympy. Currenly only FriCAS is installed in the machine
and trying to edit pages containg Maxima, Reduce, Sage or Sympy
code leads to errors, so such page can not be modified (unless
all references to other systems are removed). Also, FriCAS
in the wiki by default does not allow running Lisp code
(and maybe also Boot, I did not check that).

Currently Gnuplot graphics is disabled due to security reasons.

Installing Maxima, Reduce and Sympy should not be very hard,
so if there is interest I may do this in near future. Sage
is too big and changes too fast, installing it would be
significant effort, so I will not do this.

BTW: There were various ideas about possible replacement for
the wiki. ATM wiki runs old Zope and I would prefer to
switch to something else. OTOH core mathaction code is
less than 2000 lines and I think it could be reused
with different wiki engine.

BTW2: A first in new machine performance was very bad, trying
to edit pages lead to timeouts. It turned out that wiki was
running latex in directory contaning almost 140000 files
and that was very slow. Now wiki runs latex in different
directory and this is faster. Still, edits arr not very fast,
but probably faster than old wiki on old machine.

Little update: I have now installed Reduce (snapshot from
March 2023), Maxima 5.30.0 (newest one for which our TeX
output code works) and Aldor (from current git).

I am not sure if Reduce is fully functional (official installation
method did not work and I installed it in a hacky way), but
simple Reduce things work, which should be enough to edit/
regenerate pages containing Reduce code.

Hi Waldek,

thank you for your effort to (re)establish wiki.fricas.org.

Hi Waldek,

thank you for your effort to (re)establish wiki.fricas.org.

There are old links like

http://fricas-wiki.math.uni.wroc.pl/FunWithFunctions/

Can you set a permanent redirection (301) to wiki.fricas.org?

Ralf

[Waldek Hebisch]

Done now. OTOH I do not know how long I will be able to keep
this.

No problem.
https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/301

Since you have established the new site, I probably can safely change
all the links on fricas.github.io to the new wiki site.

The redirect is only important for the search engines to update their
caches.

Ralf

Old site at fricas-wiki.math.uni.wroc.pl is now gone and not
coming back. Please use only wiki.fricas.org in links,
old address will fail.
