Hey Bookowl! Do you think you could find a solution to the jumping hover issue and fork my pen with the solution? I don't care if the solution requires JS… just get it to work please.

I'd suggest using x10, not 000webhost. The latter tends to be somewhat unreliable, and puts ads in your page.
GH pages works with custom domains (search for CNAME file) and is super easy for everyone to contribute to. Let's use that. (Oh, and they give crazy fast load times.)
OK, I'll take a look.
I agree to using github pages.

Well, I've already set up it using 000webhost now - I'm just waiting for everything to update now. I cancel the domain + account if you like though

Oh…. lol.
No clue why I didn't think of that.

@chooper - don't cancel the domain, but the account will probably be unnecessary.

PullJosh, I can't seem to find any issues. Could you please describe the problem to me?

I am trying to experiment with convolution kernels for stuff like edge detection. Here is what I have so far: https://scratch.mit.edu/projects/76374468/
It doesn't seem quite right though - it seems very over reactive.
The kernel I am using is
[ 0 1 0
1 -4 1
0 1 0 ]
Could somebody else take a look at it, please?

It's over my head, but @gtoal has this hidden in some of his projects. You may want to take a peak inside one of his.

It's actually the base for all the filters in this project.

I'll create a Github organization. We need a name, though. What should I call it?

Why not just ScratchNPR? Also gh org names iirc never have hyphens and are CamelCase, while repo names have no uppercase letters and are snake-case

studio question… it currently says “75 projects” but the display is a number of complete rows of 4, so there can't be exactly 75 showing - however there's no “next page” button anywhere! Where are the missing projects? (at least one example: my warholiser is not on the page anywhere)

Scroll down and more projects should appear…

No, they don't! Hmmm… I wonder if something is broken because I have the Tampermonkey extensions active again? I turned them back on a few days ago…

I might go rename SoundBlocks to soundblocks, Cats-Site-django to cats-site-django and Cats-Site to cats-site next time I'm on the computer.

Also I notice that when you remove the mouse from the zoomed image, it fades gradually but when you move into the image it appears immediately. It would be better to fade in the same way as it fades out.

It seems that the issue is rather sporadic - sometimes it works, sometimes it doesn't.
Also, I'm on Chrome (and I'd wager gtoal is too).

brightness is often a negative number. You then set r, g, and b to brightness. Something is wrong there since you can't have a negative colour… can you?

Maybe normalize the result to 0-255? or pink if brightness >20, grey otherwise?

Any of the above.There might be a ‘right’ answer in a math class but not when the end result is for art…

another option is normalisation on some sort of non-linear scale to emphasize the median of the values. Sqrt or Log for example.
