Emacs has this too, with ‘undo-tree-mode’.

(Incidentally, the documentation is wonderful: ‘The only downside to this more advanced yet simpler undo system is that it was inspired by Vim. But, after all, most successful religions steal the best ideas from their competitors!’)


undo-tree-visualize is easily one of the biggest wow factors for unfamiliar users. Cannot unsee, cannot go back.

Strange, I love GNU screen, and find the key combinations very easy and intuitive. However, I could never seem to master GNU's Emacs and what I find are very strange default key commands. I love vim for the reason of, what I personally find, very intuitive key combinations.

I just downloaded VSCode for the first time recently -- which I was delighted to find has a VIM mode. From what I read VSCode's VIM mode does not respect the undo tree of actual VIM.


A good number of Emacs users work with Vim key bindings. evil-mode is very good. I use Doom Emacs, which uses evil-mode by default.

fun fact: sublime text also has a vim mode (called "Vintage mode" which is just hilarious) that is built-in but disabled by default, rather than an extension like in vscode. vim keybinds are just the best.

I had occasional problems with undo-tree (the tree broke occasionally), I've been using vundo for a while now and I'm a lot more happy with that.

The mark and diff functionality is great too.

Another day, another great Emacs package I’ve just learned about. This one’s going in the init.el for sure!

I haven’t been using Emacs for a long time now, but isn’t the Emacs way better? With undo tree you don’t lose any history, but the same is true for what Emacs does by default and it is much easier to navigate the history, since every change is part of a linear history and undos and redos also get added to it.

Neither can I. Luckily tweaking the colours can make it somewhat readable. (Sometimes…)

This is a very strong theme throughout Ursula Le Guin’s books and short stories; perhaps you might find those interesting.


> extremely cold temperatures (267 °C)

Sorry?

(I have a feeling someone meant Kelvin, though 267 K is hardly ‘extremely cold’ either…)


Maybe a negative sign got dropped?



negative 267 C would be 6 Kelvin ???


That's pretty standard for experimental quantum systems. A lot run on helium fridges at 4K. The superconducting stuff even colder, in 10 mK dilution fridges.


> The analogy of the Talmud to a hypertext isn't especially apt, IMO.

Isn’t it? Every page of the Talmud includes marginal notes (Masoret HaShas, Ein Mishpat, Torah Or) giving cross-references to relevant parts of the Torah, Talmud and other legal codes. In a web-based version I think it would be natural to represent those with hypertext.

True, and the website "Al Hatorah" indeed does that, for the marginal notes that you list. See, for example: https://shas.alhatorah.org/Gemara/Berakhot/2a

But my point is that those marginal notes are an artifact of the 16th century print edition. It's not anything inherent in the Talmud text.

The famous 16th-century Mikraot Gedolot edition of the Bible also features extensive marginal notes (the Mesorah) which function much like a dense network of cross-references.

In fact, the Mesorah is a medieval work (drawing on ancient sources) and is arguably was one of the most elaborate systems of cross-referencing found anywhere, at the time it was promulgated.

This differs from the Talmud’s cross-referencing, which doesn't predate the printed edition (as I note in the Seforim Blog article; the page citations are reliant on the universal page numbers that started from the first print edition).


> But my point is that those marginal notes are an artifact of the 16th century print edition. It's not anything inherent in the Talmud text.

OK, fair enough, if ‘the Talmud text’ is taken to be only the Mishna and the Gemara. (Though when I think of the Talmud it’s the printed edition that comes to mind, with all its accompanying commentary.)

EDIT: I had a look at your blog and saw you actually addressed this exact point already: https://www.ezrabrand.com/i/162112983/myth-the-talmud-is-div...


The actual paper seems to have more information: https://www.science.org/doi/10.1126/sciadv.adt9039



Don’t give them ideas!!


I’m pretty sure this case is solvable too. Click the white block, then click all the blocks which turned white after that. This flips each block twice (bringing them back to their original state), except for the original white block which was only flipped once.


This looks amazing! I recently moved to an apartment with a good view out the window, so I was excited to try this to identify some of the more distant hills I can see. Alas, it seems to have developed some bugs in the 4 years since the last commit… when I tried clicking in ‘Edit Mode’ to select a location, nothing happened and I couldn’t continue. Any chance you could look into updating this application?


Try https://www.peakfinder.com/ -- I use the Android app all the time (I have no memory of paying for it, though, maybe it used to be free?)


I’ve been using such tools already (in particular https://www.udeuschle.de/panoramas/makepanoramas_en.htm). But for smaller or more distant features, I’ve found it can be difficult to correlate their physical appearance with their appearance on the diagram. A calibration tool like hdersch’s would make this much easier!
