On: Show HN: Txt2plotter – True centerline vectors from Flux.2 for pen plotters

Yeah using AI to do a first stage pass seems to work well. I did something similar with Nano Banana: https://github.com/c-jiph/bitmap-to-gcode

I didn't actually end up playing with it too much but the problem I found was it's a hard to get a one-size-fits-all prompt. The AI generated images are usually okay but some features aren't great for a plotter or just don't look visually pleasing. It's still better than having to manually mess with the initial image.

On: Show HN: Making Python one-liner-fit with the new pwk (Python With Kurly braces)

You can do this using contexlib. For example the following in pwk:

    try: { print(os.listdir("/"+s.strip())) } except: pass

Can be written in pure Python as:

    with contextlib.suppress(Exception): print(os.listdir("/"+s.strip()))

(Assuming contextlib is imported, and you're okay with letting things which don't extend Exception slip through.)

You could probably also make a context manager which takes a function/lambda to define how to handle exceptions etc.

`contextlib.suppress(BaseException)` is possible if you really want to (although both this and the bare except clause should be avoided anyway).
