Re:Curvature Beziers on Friday August 28, 2026 @04:47PM (#49484074)
As someone who has spent a lot of my life editing bezier curves, this is really fantastic.

The one sticking point is instability in the middle of s curves which seems difficult. We're getting better control for every fully convex or non-convex path in exchange for chaos at the boundary between the two. I wonder if incorporating some other error term of the curvature in those regions might help, perhaps guaranteeing that the curvature derivatives are close to continuous whenever the curvatures themselves get too small?

One other thought is that you could use a saturating function of the tangent circle radius so that 0 curvature points don't have to have their control points go to infinity, perhaps making the saturation point a function of the distance to the nearby nodes to keep the scale reasonable.

Re:Being Ambitious and Being a Dad on Wednesday August 19, 2026 @02:19PM (#49365167)
Personally, I decided that being ambitious at work wasn't as important to me relative to being involved in my kids' lives, and intentionally pulled back. I'm fortunate that my work offers part time options, so I went down to 80%. I take two half days per week to spend the afternoon with my kids after school.

I think it may not be in the underlying BirdColorBase data, unfortunately.

I may have to figure out how to retitle it. I would not have expected so many people to think that about birds!

This is awesome. Are ordinary objects bright enough to register their spectra in it?

After doing this I was looking for some way to do spectrophotometry with a small enough amount of equipment that my wife would approve of, so that I can add more things to the list and confirm their color.

Re:Our Experience with I-Ready on Saturday March 14, 2026 @01:06AM (#47373546)
i-Ready has two products, i-Ready diagnostic and i-Ready learning. The diagnostic is solely used for adaptive testing. The learning software is used for classwork, homework, and lessons. The learning software is what this is about. Lots of schools just use the diagnostic tests.
Thank you! Two of my favorites. I'm honored.
Wow! Great suggestion. Whether to count coconut milk as milk is a decision I had not yet had to make.

My thinking at the moment is that I probably would not. It seems like further research would reveal a whole new region in the upper left, clustering with Dan Bing, of "asian milkless crepes."

Aggakake is on the chart!
It's easy, if you normalize it so that it sums to one, it drops a dimension, and becomes an equilateral triangle.
French toast isn't plotted because the recipe doesn't customarily start with flour, but if you do plot it it ends up in the lower middle. If you have exceptionally eggy challah, then you might be able to push it into the abyss, but really exceptionally eggy, like 1:1 egg to flour by weight.

A related idea that I'd like to see more people do. If you have 10-20 tweets on a subject, plug the holes and turn them into an essay on the real internet. My first step in writing https://news.ycombinator.com/item?id=46452763 was to copy a bunch of tweets into a doc.

Micro blogging is a great way to brainstorm and iterate on your thoughts over time, but eventually you have enough material to graduate from micro blogging to blogging, and more people should do it.
