>-sure, but weirdly the effect has to be wavelength dependent, but there are no color fringes.
I do think you can get colour fringes in some circumstances. Try doing it in a dark room with a bright light coming through a small gap (e.g. between curtains). Like:
IIRC you can get colour fringes between the finger and the top edge of the gap behind it.
EDIT: I just tested it, there is definitely a rainbow spectrum between the finger and the gap. The gap side is blue and the finger side is red. Not sure if this is the same effect as the article though.
I've been bothered by this for decades. I remember arguing with my HS physics teacher that this couldn't possibly be single-slit diffraction, for the same reasons the article brings up. I was never able to figure out a satisfactory answer for what it really was, even after a physics degree. Feels good to be vindicated :D
There are many features of Excel that LibreOffice Calc doesn't support. Most importantly: structured references, VBA, PowerQuery. Not to mention its UI is very laggy even on powerful machines.
For real financial/business work, Calc is just not a serious player.
I have a spreadsheet I've been using since 2017 to track all my spending and savings accounts on a weekly basis, plus some trend analytics, plus some simple graphs on multiple sheets. A few hundred rows and columns, both entered and calculated values (simple formulas, nothing fancy). Haven't noticed any slowness. When I have some data to look at (like .csv or even .xlsx), I always use Calc. I work with Excel at work all the time, it might be faster on larger data sets, but Libre's Calc is more than enough for many use cases.
It works but produces pdfs. That becomes a problem. More importantly, you spend FAR more time writing documents using latex than word. The friction is enough to make writing legal stuff with it not worth the pain.
Writing long documents in Word is painful to the point that people prefer to stick to old tools like FrameMaker.
It's also painful in a different way than LaTeX. While LaTeX is complex but deterministic, Word just eludes your efforts in a way that does not build a coherent mental model but rather a loose set of fuzzy rules learned via frustration.
I deeply believe that this was by design and is in general part of Microsoft culture, creating a separation between programmers and users to make them suffer in their own ways. No wonder Bill Gates became a philanthropist in his later years. He knows better than anyone that future historians will figure out all the evil he expertly inflicted on the world.
A proper single-pane WYSIWYG editor that uses Typst under the hood would be able to stop the MSWord train by matching the features end users need.
- Small caps, no problem.
- Multilevel heading numbering, no problem
- Table of Authority, no problem
- Line numbers, no problem.
- Paragraph numbers, no problem.
- For missing features the community is more than capable of providing extensions to fill the gap. Redlining would be an example.
The first argument actually leans in favor of LaTeX or Typst as a better replacement for Docx.
A LaTeX or Typst document can contain both the content and formatting together within the same file. This isn't idiomatic for either language, and my experience is that this is more common for Typst than LaTeX, but both can do so. All of those formatting rules like small caps, table widths, margins, page numbering, etc.? Those can be rigidly defined in either LaTeX or Typst and are better guarded aginst accidental formatting rules breaches from double click, copy/paste, or table cell insertion than in Word.
I'm more sympathetic to the network effect argument. It's hard to envision a reasonable redline system compatible with both Docx and LaTeX/Typst.
>Auditors obsess over encryption at rest—from laptop FDE to databases’ security theaterish at-rest encryption—and over encryption in transit, usually meaning TLS.
Very hard to parse sentence. The monospace font means the em-dash isnt emmy enough, so I couldn't tell it apart from the hyphen on first, second, and third attempt. I wish people would put spaces around it, and to hell with what the style guide says.
