fooofw··on Microsoft accidentally revealed a UI design prototype for the next Windows
Maybe this one: https://youtube.com/watch?v=BVIN_PJu2rs

fooofw··on CS quotes found while browsing Notepad++'s code
And xdisp.c in Emacs: https://github.com/emacs-mirror/emacs/blob/master/src/xdisp....
fooofw··on VS Code Org Mode
Org mode actually uses both square and angle brackets for timestamps [1], but the square-ones are inactive, i.e. they don't show up in the agenda view. I guess the angle ones are the most useful, though.

fooofw··on Pretty inline symbolic mathematics in Org-mode
You can also tap into the entire Jupyter system using emacs-jupyter [1] which also includes an org-babel component – and it looks like you can preview the LaTeX in Org mode given a few options options [2].

fooofw··on Bash functions are better than I thought
I feel like this comment is almost a kind of inverse of https://news.ycombinator.com/item?id=23424853 (which I remember to have found interesting).
fooofw··on Too many new papers may mean novel ideas rarely rack up citations
I don't know if it makes any difference, but if PageRank should replace the h-index, the most direct equivalent would be to rank the authors rather than the papers, no?
fooofw··on Project Jupyter Celebrates 20 Years, Fernando Pérez Reflects on How It Started
VS Code has a lot in common with webbrowsers. VS Code is (as e.g. the older Atom) mostly implemented using web technologies HTML, CSS and JavaScript that execute in a runtime forked from a browser (Chromium).

I assume the grand parent is, at least partially, referring to this essay [1]. Here, the browser and HTML/CSS/JS is complimented for its dynamic nature and low barrier to entry, similarly to Emacs. In that sense, VS Code, like Jupyter, is a perfect example of the webbrowser gaining functionality of Emacs.

fooofw··on Worse Is Better (2001)
This reminds me of the "Principle of Least Power" and variations [1, 2] in relation to the design of various languages of WWW. Although that is supposed to describe languages that are not programming languages. E.g. [1]:

> Computer Science in the 1960s to 80s spent a lot of effort making languages which were as powerful as possible. Nowadays we have to appreciate the reasons for picking not the most powerful solution but the least powerful. The reason for this is that the less powerful the language, the more you can do with the data stored in that language. If you write it in a simple declarative from, anyone can write a program to analyze it in many ways. The Semantic Web is an attempt, largely, to map large quantities of existing data onto a common language so that the data can be analyzed in ways never dreamed of by its creators. If, for example, a web page with weather data has RDF describing that data, a user can retrieve it as a table, perhaps average it, plot it, deduce things from it in combination with other information. At the other end of the scale is the weather information portrayed by the cunning Java applet. While this might allow a very cool user interface, it cannot be analyzed at all. The search engine finding the page will have no idea of what the data is or what it is about. This the only way to find out what a Java applet means is to set it running in front of a person.

fooofw··on SARS-CoV-2 Gamma variant infected 16 fully Pfizer vaccinated Guiana gold miners
I think the "4" should be changed to a "1" yielding p = 0.0333. 4 is the total number of unvaccinated miners without prior infection.
fooofw··on Denmark to permanently cease using AstraZeneca vaccine
Yes. Elsewhere in the thread, I linked the official Danish vaccine calendar [1] (from today, April 14) which estimates that 65 years and above will complete vaccination end of May, though this is subject to change based on actual deliveries. The vaccines in the plan do not include AstraZeneca though they do include Johnson & Johnson as can be seen from the more detailed plan [2]. Neither plan is available in English unfortunately.

fooofw··on Denmark to permanently cease using AstraZeneca vaccine
The current official Danish vaccine calendar [1] (updated April 14) estimates that the group of citizens between 74 and 65 years will complete vaccination end of May.

fooofw··on Differentiation Under Integral Sign (2015) [pdf]
This trick can also be used with the Gaussian integral to compute similar integrals of a Gaussian multiplied with a power of the integration variable [1], e.g. the integral of x*exp(-x^2).

fooofw··on Emacs Symbolic Integration
Of course, in this example, the symbolic calculus functionality is distributed with the OS, or arguably even as part of it, which I guess is a bit more rare than simply having the option of installing it.
