I saw today that my CoCalc (cocalc.com/) license was about to renew. I've been meaning to move to a more #SelfHosting or #P2P paradigm, so this was good timing for me to cancel. I left this message when doing so:

"I want to support Sage, and I like using CoCalc, but I don't want to put money towards a service that supports Microsoft, Amazon, or OpenAI in any way. I didn't care so much about this before, and I even log in to CoCalc with a GitHub account, but I'm tired of having my work scraped for profit by people who donate to fascists who are destroying my nation. I would consider returning if all ties to these corporations were cut and cloud computing services came from responsible companies, perhaps in the EU."

I'm pretty sure I already have backups of everything I want from GitHub, so I can be done with them too. I should have quit when Microsoft first arrived. My plan is to switch to Radicle (radicle.xyz/) rather than another centralized service. I'll be sure to post about how that goes.

"Between 2019/20 and 2022/23, the University [of Cambridge] paid £12.6M to seven major commercial #publishers: #Elsevier, #Wiley, Taylor & Francis, #Springer, #Sage, Oxford University Press (#OUP), and Cambridge University Press (#CUP). This was the highest expenditure among 21 UK #universities that provided data."

Грядёт замена #wxMaxima ?
Оказывается в #KDE предлагается универсальный GUI для систем математики: #Cantorhttps://apps.kde.org/cantor/

Заявленный перечень environments включает: #KAlgebra, #Maxima, #Sage, #Scilab, #Qalculate Т.е. полноценные, давно и хорошо известные системы computer algebra system (CAS) or symbolic algebra system (SAS).

Хотя это скорее дополнительный вариант, тем кто на #linux привык использовать #wxMaximahttps://wxmaxima-developers.github.io/wxmaxima Решает в алгебраическом виде уравнения и системы, численные вычисления, построение графиков. По возможностям близка к Maple и Mathematica.

Из забавного позволяет видеть графики в динамичном виде:

И в целом всё то, что потом перешло в питоновский Jupyter как notebooks:

Does someone have access to this paywalled editorial in a #Sage journal?

CNRS nor my uni do, and not even a convenient passe-muraille.

This is the obituary of a 56-year old researcher. The reason I'm asking is a rather shocking way to cite his work.

One of his co-authors now published a paper in which whatis said is his greatest achievement is reproduced in length, with a slight addition, and at last on p8 cites:

"After lengthy manipulations [25], we can rewrite eq…"
