"If you refuse to estimate, you’re forcing someone less technical to estimate for you."

This is the perfect approach, given that estimates are top down and work to fill the estimate is bottom up.

"When I estimate, I extract the range my manager is looking for, and only then do I go through the code and figure out what can be done in that time."

I like the surface dots like it is. It gives me two points of reference at the poles, and adds intuition for how long it takes to go around the sphere.

From that wikipedia article, delta is the ratio of y variance to x variance. If x variance is tiny compared to y variance (often the case in practice) then will we not get an ill-conditioned model due to the large delta?

> They typically need to compare many or all points to each other, leading to O(N²) complexity.

UMAP is not O(n^2) it is O(n log n).

Polars made the mistake of not maintaining row order for all operations, via the False-by-default argument of maintain_order. This is basically the billion-dollar null mistake for data frames.

What a gem of a quote. A great way to avoid becoming a bitter person.

Without proof there is no confirmation.

The pro version comes with "Professional-grade creative suite", but they don't tell you what you're actually getting. It's just opaque corporate-speak one-liners "Make real progress toward your goals".

Except on figure 1 they're all at 0, making it look like the authors didn't know how to use the models or deliberately made them do nothing.

That was released as a joke. Twenty years later and no longer released as a joke, Apple is showing they are still in touch with the sensibilities of the modern Apple customer.

Correctness with respect to the benchmark. A slow reference renderer could produce the target image, and renderers need to achieve either exact or close reproduction to the reference. Otherwise, you could just make substantial approximations and claim a performance victory.

There has to be a better way to view this than the tangled web of overlapping lines, like that at lower left of the "services" rectangle on the right, even with the selection highlighting. Perhaps there is not, and it is fertile ground for developing a new visualization.
