As an aside, the fact that I saw the paper on perfect pitch acquisition and turned it into a usable app within a few days is one of the things I love most about being a programmer. When a tool doesn't exist, you can just make it, and make it how you want it to be!

@marcogorelli I think for adults there are established techniques for improved ear training. I am not sure if simply doing those as often as we do the chord identification method trainer would give a similar probability of attaining perfect pitch. It seems like kids with early exposure to music are pretty significantly more likely to get perfect pitch and have the kind of intuitive relationship to music that a lot of musicians have, so it might be that pretty much any sort of ear training will work when you start this young.

@marcogorelli To be clear this is for teaching children to have perfect pitch. I think there are some implied claims there about a critical period for learning perfect pitch. l am also mildly skeptical of the somewhat grandiose claims in the paper (100% success rate for all children who completed the program), but I have always been very interested in things that alter your perception of the world, and if there is a critical period I wanted to make sure I got in there.

My son is getting really good at it at this point, and there's at least one other person actively using the app who is a bit ahead of him who can get perfect scores on at least the first 9 levels.

@mariatta In case you didn't find it, Wikipedia has a good write up on the varied things that is called: https://en.wikipedia.org/wiki/Number_sign#Names

I like "Octothorpe", but I don't think that's nearly as common as "pound" or "hash" in American English. (Hashtag as the name for that symbol seems to have skyrocketed in the past 10-15 years).

It is all open source and designed to be easy to fork and deploy if desired: https://github.com/pganssle/cim

If you are good at web design or music theory I'd be very happy to see contributions (including just giving feedback)! Doesn't take much to be better at those things than me... 😛 ([Exhibit A](https://github.com/pganssle/cim/issues/9) 😅)

I spent a lot of time this long weekend making improvements to my perfect pitch training app: https://pganssle.github.io/cim/

I'm pretty happy with how it's shaping up. My son has been using it 4-5 times per day (the sessions are frequent but short), and it's kind of amazing to see how good he is at identifying chords.

So I figured out how to do this with Inkscape, it's just a bit wonky:
1. Make your shape as a simple path
2. Set the size of the shape to be between 0 and 1 (width and height) in some base unit
3. Set up the document so that the scale is 1 of whatever your base unit is.
4. Save an optimized SVG (not always necessary) to get a maximally simplified path (with no transforms or whatever).
5. Open with a text editor and copy the path into your `<clipPath>` SVG.

If that doesn't work as expected, you may have to copy the path and paste it into a new document after it's been scaled and moved.

If that's still not working, you can copy-paste the path into this tool and play with the scaling: https://yqnn.github.io/svg-path-editor/

Some of the shapes I want to draw can be accomplished easily enough with regular CSS polygons, but I want to clip with something like star, crescent moon, teardrop, heart. I would much prefer to build that stuff in Inkscape or something.

Does anyone know a good tool for #linux that I can use to draw shapes and output clip paths for use in #HTML/#CSS that work to clip stuff?

What I'm getting from #inkscape is not clipping my divs correctly. Here's a MWE:

(There should be three divs there, with the left two clipped on rounded triangles)

@BryanGreyson Nice! Next time I have time / inclination to switch to a custom OS I'll have to give it a try.

When are they going to add an app-specific "Contacts sandbox" for Android — or the ability to do app-specific spoofed permissions in general?

It is annoying that I either give WhatsApp *all* my contacts or *none* of them. For stuff like that I'd like to be able to share contacts on a per-contact basis (with the app unable to tell the difference between partial and full contact lists, mind you).

Something *like* that exists for file system permissions already. I'm surprised I haven't seen it in any custom OSes or mods.

@tonybaloney `python -m http.server`? 😛

@brettcannon I seem to remember @glyph might have gotten the same one? Or considered it?

@brettcannon This is the one we bought, very basic, runs over local RF: https://www.amazon.com/gp/aw/d/B00ECHYTBI

We broke one after about two years and bought a new one, which we just gave away to family members (ones we like) recently.

As far as I know you can't use it to record video or audio. It has a talk button that is sometimes useful, but also sometimes used to freak out our older one.

Range was decent (though not compared to an internet-connected device). We could go outside when we lived in a townhouse in NY, and when we had a big suburban house it reached the whole thing plus the yards.
