I plugged it into an older Vizio. I could see the initial burst of kernel type messages then the tv said no signal. Damn, am I calling the UK for support? Then I tried my much larger 2 year old RCA in my bedroom. 15 seconds and the graphical desktop came up. 5 screens later (language, keyboard, password, wifi, update) and it started grinding, and I had the full desktop up while it is updating. And the update just errored. Well, time to click for a while... ... back. Not an issue, random package not available. Total update time about 10 minutes, reboot in 15 seconds. I felt my code slipping away, and I wanted to play on something open and well documented. Cheap helps too. I love this thing (so far).

Yup.. things re Intro-to-Geo-Boole ..have advanced quite a lot since er, Sinclair (And Otrona /CPM--the Expen$ive 18# 'portative' with the 5" green-screen with full 80 characters). ..unlike the scroll-screen sewing-machine-heft of the Osborne1* (They who committed seppuku by pre-announcing a Model Two! {Duh}. * Lee Felsenstein was a fun-guy (designer of that package) ..talked to him when he wanted some Tweak™ I was peddling: the magick 'contact cleaner' which really worked--told him the small bottle was on-the-house and thanked him for the brilliance of the (moi's) first purchase in this Time-sink field. (Had I one such) I might create a motion-sensor input + Raccoon-recognition kluge: to LOUDLY play a Mountain Lion screech. And other such vital things we never ... did ... complete. A whole damn computer in a colorful box. Have fun.

Going through the tutorial for the simple environment I hit this: https://codewith.mu/en/tutorials/1.0/plotter With this running full speed, no delay, I see the editor use 97% CPU (maxing a single core with 3 cores left) and a python process taking 15 to 20% of another core. I have no system lag in any other windows, and I have a bunch of active web pages, top process, etc. I wanted to see how local system file system speed was. Historically a "find / -print" was a pretty good indication. pi@raspberrypi:~ $ time sudo find / -print \| wc -l 331024 real 0m1.923s user 0m0.677s sys 0m1.133s Instantaneous from my point of view. I've been out of the game for about 6 years. This thing is far faster than anything I've had before other than servers starting at $20K. Does anyone recommend a Python development/education environment other than Mu for me to try?

I've got it installed on my work machine for a few tasks, but haven't played with it much. https://www.anaconda.com/products/individual DeLong seems to be doing more of his teaching in Jupyter notebooks. https://jupyter.org/ I don't know anything much about trying to install them on a Raspberry Pi. HTH a little. Good luck! Cheers, Scott.

My current go-to is JetBrain's PyCharm. It runs on the Pi 4. (I only have up to the 3B which may be a bit too flimsy for that thing - haven't tried it on ARM.)
