  • Usually you do this with venv. I’m sure there’s a cool kids way to automate everything but it’s not that hard to just download 3.10 (or whatever version you need), compile it, install it into a 3.10 directory, and point your path at it.

    I don’t like Gnome either. I’ve been using MATE which is pretty straightforward, and looks like old-fashioned Windows. Not saying that’s a good thing, but at least for me it had very little learning curve.

    If that project requires Python 3.10 and won’t work with 3.13, that may be a problem in its own right.


  • If you’re unfamiliar with PostScript or basic linear algebra, I would start by reading a book or tutorial on PostScript. Not to know how to produce PostScript output, but rather to understand how it handles coordinate transformations. So your drawing program can have nested objects with a transformation for each object, and the transformations compose through the nesting levels. Then you can rotate and scale complicated figures by just changing a single transformation, which is a 2x3 matrix. It’s really 3x3 but in “homogenous coordinates” so you only have to store 6 of the numbers.

    Obviously, also play with other drawing programs to get ideas for what you want yours to do.

    There are also tons of books on computer graphics, though maybe not specifically about drawing programs. The ones I’ve looked at are way old by now though.
















  • I don’t understand what you’re asking: you want some kind of graphical display of the file structure? Grep per se doesn’t do that, but maybe you could match the output against “tree” output? I generally just use M-x grep in Emacs which doesn’t make a tree-like display, but lets me navigate to matched lines by clicking on them.




  • The old fashioned belt pagers that copier technicians used to wear. You could call a phone number and send a numeric or sometimes text message to the person’s pager. They were one-way, receive only, so the message would normally be your phone number and the person would go to a landline phone and call you. That was before everyone had mobile phones.

    You can still get those pagers and the privacy attraction is that they don’t send anything like your location back to the phone carrier. Instead they are basically broadcast receivers, and the message is broadcast to your whole reception zone, typically the size of a city but potentially bigger on the fancier plans.

    Service appears to start around $15/month per a quick search I just did. That’s more than I pay for unlimited voice and text plus a GB of data on my crappy MVNO cellular plan. So they aren’t that good a value for most of us in this day and age. But they do still exist.

    More info available by web search.


  • It really doesn’t seem like a winnable situation. A ton of phone functionality that people rely on (always-on internet everywhere you go) is fundamentally invasive no matter how the phone is built. All you can do is decrease your reliance. There have been a couple of threads about POCSAG pagers but you have to be pretty dedicated to pay for one of those, and they are still just one way. Anyway trying to be really paranoid about this stuff warps your mind.
