RK4 is about as unstable. The backwards Euler method is baby's first stable ODE solver. If you want to make RK4 stable, you have to change it into the implicit RK4 method. However, the Lorenz system isn't stiff, which is usually w

Mercurial always has had sequential revision numbers in addition to hashes for every commit. They aren't perfect, of course. All they indicate is in which order the current clone of the repo saw the commits. So two clones could pull th

Still not quite the same, because absorb splits up your working directory changes into all relevant commits, as deduced by diff context.

Yes, hg has changeset evolution. A meta-history of editing propagates when you push rewritten commits. https://www.mercurial-scm.org/doc/evolution/

No, the point is that you don't have to mention the hash at all, it's automatically deduced by diff context.

Absorb is fantastic and one of Jun Wu's (seen in this thread as quark12) best contributions to Mercurial. I want everyone to know about this tool, it's amazing. I had fun trying to come up with a name for the feature: https:&#x2F

Ah, there it is. I was wondering when this would happen. Facebook used to be involved with the Mercurial community, but it was difficult to work with them. They always wanted to do things their way, had their own intentions, and started to

Hard to tell at this resolution, but it looks like he's using a fairly bare X setup with a tiling window manager and only one Emacs frame on the left. The colours and layout on Emacs look like org-mode. Does he write with org-mode? I w

Emacs windows. There are no panes in Emacs. The Emacs window is held in a frame. The operating system calls that frame a window, but that's not what Emacs calls it. https://www.emacswiki.org/emacs/WindowsAndFrames

This reads like a marketer wrote it. "A perfect fit for my own engineering training". It's vague and feel-goody and adulation for the company. What parts of Amazon did you not like?

Interesting point. Speculation that rootkitting all of your employees made the problem worse: https://twitter.com/BillDemirkapi/status/1506117152461496323

Came here to say this. If it's text, Emacs can handle it. Oh, also, if you want your ASCII diagrams to render into pretty pictures, I found org-mode + ditaa to work quite nicely: https://www.orgmode.org/worg/org-co

I personally really like x-splines: https://inversethought.com/jordi/xsplines/ I find them super-intuitive to use. The fact that at each node you can make it close, sharp, or interpolating is quite helpful. They&#

I am very frustrated and confused by your usage of the term "increase relevance" when it seems to me that Pinterest did exactly the opposite: provide images without context, without relevance. It's a situation many people are

Your dad is a product of the salary taboo. The salary taboo creates a weird societal emphasis that associates a person's worth to their income, hence to certain kinds of narcissism.
