It's interesting that even clear advantages like `jj undo` are hard to communicate because of this.

Jujutsu has "first class conflicts", but it's different from Pijul's "theory of patches". As far as I know, the other big stuff like "working copy is a commit" and the "operation log" (which

This immediately played in my head when I read the headline.

One thing I really appreciate is that you can run `jj new master` at _any_ time to drop what you're doing and start a new change. The way jj handles the working copy, conflicts, and visible heads means there's just no need to thin

Part of this that hasn't been mentioned is that the mirror is thicker than you might expect. The observatory's website says 12.5 inches (though it will vary somewhat across the curved surface).

If you're trying to do it all in software, you can get pretty far with a function to draw a solid colored triangle, a function to rotate 3d points using sin and cos, and some loops. Then the other pieces like lighting and texture mappi

The image from a single curved mirror or lens will have distortions that can be reduced by adding additional curved mirrors/lenses. It's also harder to make and use large diameter lenses than mirrors. Each lens has two surfaces th

The sun is about 400,000x the brightness of the moon, with about the same apparent size. So I think the full moon's brightness concentrated 100,000x would be almost that bad. However, having the sun in your field of view momentarily do

The debris orbits from an initial collision don't have to be stable to allow a chain reaction that produces debris in more stable orbits. Debris from even a single low altitude collision/disintegration could collide/disintegr

Debris orbits like anything else. Regardless of the orbits of the colliding objects, the orbit of any debris is only really constrained to intersect the point of collision. For some debris, the point of collision could be the lowest point i

If considering a trip to this area, be sure to read about McDonald Observatory's star parties and especially the special viewing nights. It's one of the best places to look through a very large telescope in a very dark place. Even

I get the feeling that depends on who you ask at this point, but there has apparently been some recent development of the hosting platform ( https://nest.pijul.com/ ). I don't know if it can have as good of a Git interop

One of the ideas behind Pijul is that implicit vs explicit diffs does make an important difference sometimes: https://pijul.org/manual/why_pijul.html

If your files are under version control, you already have a generic change detection mechanism that can give you a shorter list of changed files that need to be checked for formatting. For example, you can run code formatters in pre-commit

I think it's more to maintain pressure in the tank, in cases where the remaining fuel doesn't vaporize sufficiently on its own (autogenous pressurization). Otherwise, I guess atmospheric pressure or compressive force from the engi

I've heard of using a gas driven plunger in fuel tanks, but I can't remember the name of the vehicle that did this. Starship uses small "header tanks" that have a similar effect. Weight and reliability are big priorities

No. If you look at the map you'll see that there's an equally sized coverage gap at each pole. I don't know if any reliable source has stated whether they will put any satellites in orbits that can cover the poles, but I imag

The data on this map makes it look like they're going for pretty uniform coverage already. Is there a source for the early orbital planes having a specific purpose? The earth rotates underneath each plane, and the times of day it will
