Jupyter Service Restored


...But for how long? 

When will GitHub's Jupyter service, historically unreliable, go out again?

For me, this lights-flickering sense of abandonment, kinda Langolier-like, is a useful prod, to myself especially, to get School of Tomorrow presenters more adequately equipped in their personal workspaces. What's a "Langolier"? Reddit poster: They are the keepers who erase ANYTHING that is irrelevant or no longer has purpose.

To whit: clone the GitHub repo locally (what GitHub is all about facilitating) and then keep pulling my updates to your copy. You're free to boldly go in your own direction with my stuff, obviously, however, I'm suggesting a "quiet pool" i.e. a mirrored version, where the only changes in that particular directory are coming from my GitHub repository.  

Having such a "quiet mirror" does not preclude any amount of noisy partying in neighboring directories (different Python projects). Use uv? I don't, yet.

"What's all this geekspeak?" you might be asking. To whom do I suppose I'm talking? Why, other geeks of course; this is how we sound. Geeks learning and teaching Synergetica, using Pythonica, that's what we're up to, among other things. 

We also get into cryptography some, mainly public key (yes, RSA), even if some industries are planning to deprecate what, today, is taken for granted inside of every web browser. My excuse for sticking with RSA is because the literature is mature and features some of the same heros (Euclid, Euler, Fermat...) that we're meeting in other Notebooks. V+F == E+2, right?

However don't think of me as unique in having high school level onramps to RSA via Python. Phillips Academy at Andover used the same playbook, I even met one of the coauthors of their text. My time on edu-sig (a Python listserv) taught me a lot.

Most of my new presenters will be on the younger side, or the quite a bit older side, with a drop off in between. That's my prediction, as a data scientist. 

GitHub's service was part of my Clarusway classes as well, during my tenure as a data tools and skills teacher. I'd help students address perennial challenges in statistics. How to deal with outliers is not new with computers, although yes, computers have helped the science (data science) evolve.

The younger side is adventurous and eager for novelty, whereas elders are ready for that 2nd or 3rd look at the material, and a fresh start appeals. Those in the middle have made commitments and are staying on top of a chosen game. You can't play every part in a Shakespeare play -- unless you're Johnny Stallings.

Like, if you already have a job that involves climbing a ladder, you don't have the same freedoms as (a) those not yet committed to any ladder in particular and (b) those who've climbed a few in their day.

Am I saying I do my slides in nursing homes?  Yes, that's how I updated that U of O guy, when he wondered after Wanderers, that time I visited the adult education discussion group in Eugene, a member of the Lanahan party.

Or rather: I'm making my slides available to those in assisted living campuses, many of whom I know, as we're aging out, I'm 68 (but still in my own home). 

So you might be a Wanderer who already participates in revolving Show & Tell programs, an easy format for engaging broad participation, usually a goal. 

Zip through a deck at high speed saying something along the lines of: "for the slowed down version, come to room 180 at such and such a time" where you'll have recruited those few with an honest interest, some former math teachers I bet, and with the stamina for a deeper dive into it.

So am I saying I expect seniors to learn Git, this late in the game? Sure that could happen (hint: it's just typing, like typewriter typing) but let's remember how late it really is: people entering nursing homes have already had a whole career using Git, invented by Linus Torvalds, one of our long time Silicon Forest residents. BTW, I'm no uber-meister when it comes to Git myself. I know enough to get my work done.

Seniors won't have to "learn git", rather they'll be trying to not forget it.  

Enter Pythonica (programming = working out; like in a gym), focusing on Synergetica (right brain intuitive, imaginative).

I dashed out the above video before heading off to a somewhat impromptu catch-up with my primary. She wedged me in. We're jiggering with my blood pressure meds. I'll be seeing her again later in the summer.

Yes, I'm a senior myself. Great discounts!
