I recently wrote a book using Libreoffice and Microsoft Word, because the publisher demanded it. The process took about a year. My own estimate is that we lost about 2-3 months to tool-related problems, without any benefit whatsoever. I have never in my 20 year career understood the point of word-processing tools, and never will. And those tools make money. That is wrong.

Would you have had tool problems if you had just went with Word?

> My answer to this question was that we need lecture notes stored in plain text files (like rmarkdown files) and data stored in csv files with direct links.

When I think of lecture notes I think of two uses:

1. An informal reference/mnemonic for the lecturer. This use suggests a format that suits the particular lecturer (which may not necessarily be text, or even a digital format).

2. Potential answers to exam questions for situations where there are too few instructors (i.e., lecturer plus TAs) chasing too many students over too short a time for students to practice critical thinking.

Are there other uses? If not, I can imagine standardizing notes across schools could be a detriment by streamlining "plugging-and-chugging".

Earlier quoted context omitted.

Unicode has some symbols. But there is limited ability to arrange them freely. e.g: representing a continued fraction in plain text seems a very futile exercise.

The "Unicode Nearly Plain-Text Encoding of Mathematics" standard[0] can do this just fine. :) a_0+1/(a_1+1/(a_2+1/(⋱+(1/a_n ) ))) Past that into an editor that accepts the spec, and you'll get something like http://imgur.com/a/7hBwv Disclaimer: I work @Microsoft improving on some math features, and we are the main implementors of the spec. Which makes me sad, since it is an open spec and it is really powerful! [0] ht…

I'm curious about that one - was the space necessary?

TeX users would like a word. Of course, that requires learning TeX notation for those reading it without an interpreter.

Yeah, go teach a 60-year-old math teacher to use TeX.

I will be 60 in a few months. I am a math[s] teacher. I have been using TeX since late 80s/early 90s when I started using small computers.

Plaintext OrgMode notebooks exhibit every benefit listed in Minimaxir's [0] post, and have the additional advantage of powerful editor integration beyond R code. Here is an example of using the IPython kernel to evaluate inline Python code within an OrgMode document.[1][2] More information on how to create multi-language notebooks with OrgMode Babel here[3] [0] http://minimaxir.com/2017/06/r-notebooks/ [1] http://kit…

Org format is great, but the designs of many of its more advanced features rely heavily on the Emacs editor's ability to collapse metadata. Once you've built a file that uses drawers, tags, some spreadsheets, and several levels of nesting, the resulting file can be too cluttered with metadata to be easily understandable in other plaintext editors.

The future of is the solution that best meets the job.

For exchange and processing data (data != information), UTF-8 text with contextual formatting like Markdown, CSV, etc is nice as it is generally tool agnostic.

But for conveying information (information != data), plaintext sucks. That's why Markdown is a copout -- the formatting still matters... and humans don't perceive markup coding as well as the rendered result. Humans do better with visual queues when interpreting written data. Formatting, typesets, bullets, tables, graphs, etc all help use process and contextualize data.

If being able to reference information or data over time, where time > 10 years, you need to think about what you're doing. (Archivists do this professionally.) PDF is the quick path to address this for format-sensitive applications, as big & important institutions like the US Courts use PDF for their documents -- it isn't going anywhere. Big datasets are more complex to deal with... you have to decide whether the raw data should be preserved vs. the processed/analyzed data, etc.

There’s no such thing as “plain text”. Is this UTF-8, latin-1, 7 bits ASCII…?

It's UTF-8.

Is it carriage return then linefeed? or just linefeed? or maybe just carriage return? or maybe linefeed then carriage return? or maybe a different character or sequence of characters to denote a newline?

I sent someone an important text (7-bit ASCII) file once. Much later, I found that they had tried to read it using NotePad. They had spent an inordinate amount of time trying to format it into something they could read. Had they opened it in WordPad, Word, a web browser, or practically anything else it would not have been a problem, but by default text files are opened with NotePad.

Please don't get me started on tabs vs spaces.

Nope, because plain-text is incompatible with centuries of mathematical notation.

Then, mathematical notation should be simplified.

There's been some work on english language versions of mathematical expressions, which at the very least can help with accessibility.

TeX is completely avoidable. I have never used it apart from at university decades ago, before I learned Word. I have done proper science jobs where papers get written but still not needed TeX. Furthermore, in all my years surfing the internet, I have never downloaded a TeX file willingly or unwittingly.

May I share a related vignette? I have a kid in middle school, and he has a tablet. These things are often pushed as "educational". Pop quiz: you walk by, and you need to determine, within a couple of seconds, if what he's doing is actually educational. Here's what you see: lots of graphics, whizzing around the screen -or- black alphanumeric characters against a white background Now, you don't actually know , but gen…

Or the student could be a visual learner.

The learning styles theory was recently called a "neuromyth" by thirty researchers in a public letter.
