Or in a shorter sentence: getting a video to 1M views is a much different achievement from getting 1668 students in a single room to learn about something.

This is a crossword puzzle where all hints are regular expressions. At first, it looked like there wasn't enough information in the regex patterns to fill in the grid but I assure you there is and the whole thing can be filled with logical deductions alone.

The title of this posting was edited and no longer matches the title of the article linked. I wonder if anybody knows why?

I can make it more explicit that the addition is to centre the figures in the canvas.

Thanks for the reference! I don’t know this book but I’ll take a look!

That’s a great suggestion. People could immediately see what they’re drawing!

Hey there, OP here.

I jotted down some thoughts on how I think about (simple) animations and how to create them with some programming (in Python). I'd love to hear your thoughts on my write up and also what directions you suggest I take these personal explorations in.

I have been using snappify.com for over a year now and I absolutely love it.

I've used snappify to create code snippets to share on social media[1], I've used it to create YouTube video thumbnails, and I've used it to create slides for talks that I've given at big international conferences[2].

I have no affiliation with snappify whatsoever, and I'd love to see your comments on this tool.

What things look good/promising?

What's missing?

What other alternatives could I consider for similar purposes?

Article OP here! Thanks everyone for reading and for your feedback.

If you have suggestions for improvements for the article, let me know here! Thanks again.

Yes, this is VERY close to the APL way: +/ages>17

OP here; maybe I'll add a comment to the article to make the comparison between NumPy and APL for this expression. Thanks!

The guide looks very compelling! Hopefully the Worker API will make it easier for me to implement a couple of async features in an app I started some time ago...

Hey there, HN!

I wrote a simple TODO app that runs in the terminal. The GIF demo in the repo (https://github.com/mathspp/textual-todo) uses the mouse so that people watching can see where I am clicking, but everything can be done from the comfort of your keyboard.

Basic features include data persistence (doh!), sorting items by due date, different styling for items that are late, and collapsing details for a more compact view.

Let me know if you find any bugs and/or if you have suggestions for simple features that I could add to keep this app lightweight but useful!

It's quite cool how you can have coloured output in the terminal. It blew my mind when I first learned about ANSI escape sequences.

Original author here, I'll be interested in feedback about the post and use cases you have for property-based testing.

FYI my personal blog lives at https://mathspp.com/blog.

I've been looking for a replacement for that font for a long time. Do you have any suggestions?
RojerGS

Thanks for the nice words. Was there anything that was unclear or that you think was missing?
RojerGS

Thanks for the words of caution! For such a small package, I think 100% code coverage isn't necessarily a bad thing yet :P But you raise valid points!

Oh, this looks like an interesting tool! Thanks for the link.
