Oft times these are public school labs and I'm not in charge of what gets installed. Always Windows and/or Chromebooks. The private schools have featured Macs as well. However they're already using repl.it in the cloud (after Codesters in the sequence). My Decimal experiments have been in repl.it: https://repl.it/@kurner/tetravolumes I realize one may use Jupyter Notebooks in the cloud as well (e.g. that free Docker-based service etc., Mybinder I think it's called). But in this context I'm just sharing exhibits, saying "hit the run button" and showing it's at least as much fun as a calculator. Other exhibits might include Taylor Series or like that Ramanujan algorithm for 1/pi. Raspberry Pi is also feature in our curriculum segments. That comes with Wolfram Language perhaps, more like sympy and Sage, but if we can just dive in and use Decimal, so much the better (already installed with default OS). https://flic.kr/s/aHskYSMvKJ (Photo Album gives the flavor) Step one might be to get curl or wget and bash installed.

When I teach my 40 hours Python course to adults (I've got another one starting next week) I always go for conda. This is BYOD class i.e. they bring a mixed bag as to the OS -- and given teleteaching, I may not even know if they choose not to tell me. However, when it comes to this high precision fitting-together of puzzle geometric pieces, and giving a workout to that Gerald de Jong formula (came to him on a train in Holland I think it was, a Ramanujan Moment -- he's a math guy from University of Toronto [1]): that's for my younger students as well, and I'm not really in a position to micro-manage their computers either. Codesters doesn't implement decimal type (a deficiency in Skulpt and probably by extension in JavaScript?). However I can use it to import the graphics in question and display them on screen. > > > certutil.exe -urlcache -split -f " > https://repo.anaconda.com/miniconda/Miniconda3-latest-Windows-x86_64.exe"; > > start /wait "" Miniconda3-latest-Windows-x86_64.exe > /InstallationType=JustMe /RegisterPython=1 /S /D=%UserProfile%\Miniconda3 > > Then create an environment and install a few things: > > conda create -n maths jupyterlab spyder > conda activate maths > conda install -c conda-forge sympy gmpy2 matplotlib safe > > Then start jupyterlab or spyder or vscode, or IPython: > > jupyterlab > spyder > ipython > # %logstart -o logged.inputandoutput.py > > > But how do you plot 3d graphics in a terminal?

For years I relied on ray tracing i.e. Python code spit out scene description language. This approach became widespread e.g. see Antiprism by Adrian (antiprism.com). At my best, I was getting Game of Life on a 3D hexapent (with modified rules for 6 and 5 around 1). My Oregon Curriculum Network website is full of early VPython experiments (4dsolutions.net/ocn/cp4e.html). Kirby [1] Input six edges, get back out volume. Add 24 of this shape to that shape and prove outcome is 4.0 to 900 decimal places. Part of that repl.it thing. What I wrote up on Medium (linked top of this thread).
