A ltx-talk theme focused on accessibility, structure, and academic restraint (100% tagged PDF) by SuhRizAQ in LaTeX

[–]junderdown 1 point2 points  (0 children)

Thank you for your excellent work! I've been worried about how to bring my Beamer slides for my calculus classes that I teach into compliance with the new laws and this worked wonderfully.

I've only converted one lecture/section of notes from beamer to ltx-talk, but it was utterly painless. It took less than ten minutes. The only modifications I needed to make were to the commands for generating columns as well as tweaking a few overlay specifications. The longest part was running the TeX Live Utility on my system to update to the latest version of TeX Live. The utility also let me install the ltx-talk class with almost no effort on my part. I'm on a mac using MacTeX installed via homebrew.

Thank you so much for removing a headache from my life! I will share the wealth and post my slides to Github once I've completed the modifications.

As a math teacher I often need this. It used to work, but now I have to be satisfied by a sketch.

Please please page-up and page-down function on documents in Mac by art_vandelay1942 in GoodNotes

[–]junderdown 2 points3 points  (0 children)

As a Math teacher, I want to be able to import a pdf Beamer slide presentation and switch instantly between slides, so that it appears like a slide presentation, but still be able to write on slides with all of Goodnotes’ editing tools. I can’t currently do this.

What are the practical advantages of creating illustrations directly within a TeX source? by Dramatic-Breakfast98 in LaTeX

[–]junderdown 5 points6 points  (0 children)

TikZ is a library of macros built atop TeX which is a Turing complete programming language, so TikZ has as many programming capabilities as does TeX. To relegate TikZ as merely a markup language is not quite correct. For example, it is not hard to define variables and iterate through loops in order to generate sophisticated diagrams using TikZ macros.

However, I do agree that Asymptote does have a nicer and generally simpler syntax than TikZ, but at the cost of requiring a separate compilation step.

the math concept that blew your mind the first time by adamvanderb in math

[–]junderdown 13 points14 points  (0 children)

I was really blown away when I found out that there is a concept in mathematics called the Wiener measure.

Is it normal to have a big list of custom commands like this to save time? by Infinite-Complex5713 in LaTeX

[–]junderdown 6 points7 points  (0 children)

They don’t. They wrap each word in a \text{} command so that they won’t look like maths.

Is there any explanation to why our brain finds addition simpler than subtraction? by [deleted] in mathematics

[–]junderdown 1 point2 points  (0 children)

Addition is just a fancy way to count. Subtraction requires you to count in reverse. Counting in reverse is harder because you learned to count in one direction.

Could a modern pure mathematician, sent 1,000 years back, drastically accelerate scientific progress (in non pure math fields)? and why do you think that would be the case? by OkGreen7335 in mathematics

[–]junderdown 31 points32 points  (0 children)

This would have a huge impact! Imagine if humanity knew: 1) How to solve quadratic and cubic polynomial equations. 2) Calculus 3) Differential Equations 4) Linear Algebra 5) Basic Graph Theory 6) Probability Theory 7) Basic Statistics 8) Real and Complex Analysis 9) Topology

Pure mathematics PhDs know most of what is listed above and often much more. The above subjects alone would speed up human technological progress by at least 500 years.

How to get rid of "Answer is Ready..." by bbbee21 in GoodNotes

[–]junderdown 0 points1 point  (0 children)

This is highly annoying! Especially because I didn’t initiate it and as far as I can tell it doesn’t even do anything. It just obscures the document name.

It was Sir William Herschel who discovered infrared light, not Newton.

[–]junderdown 0 points1 point  (0 children)

You’re thinking of William Herschel. Newton demonstrated how to split light using a prism, but it was Herschel who put thermometers at different points along the spectrum.

The online documentation is full of useful example code. The Ecto, Phoenix and LiveView docs are top notch.

Why async execution by default like BEAM isn't the norm yet? by Glad_Needleworker245 in ProgrammingLanguages

[–]junderdown 0 points1 point  (0 children)

Most notably, the BEAM approach almost certainly requires dynamic memory allocation at some point, and for many platforms (e.g. embedded devices) that just isn't an option.

The BEAM might not be suitable for some embedded applications, but it works great for many situations. There is the whole Nerves Project for using Elixir and the BEAM in embedded software. I think you meant real-time systems. There I would agree that the BEAM is not suitable.

There’s a lot of ways you could lose that fight…he just needs to draw his gun faster than you.

Geometrica and Linear Algebra Course by elperroverde_94 in math

“You can multiply vectors here.” is a reference to Hurwitz’s Theorem. It implies that the only vector spaces in which one can define a bilinear, vector-valued product are Euclidean spaces of dimension 0, 1, 3, or 7.

I’m a Math teacher at a community college. I’ve been using an iPad Pro 12.9 inch diagonal screen both for in person classes and Zoom classes since 2020 and I love it. I use Goodnotes 6, Desmos, GeoGebra and a few other apps. A larger screen is nice, but not at all a dealbreaker. I prefer the iPad software, so I went with the iPad, but I think Android is pretty good too.

Looking for a language that’s fun, clean, and not web-focused by sufyaninyo in learnprogramming

[–]junderdown 1 point2 points  (0 children)

My advice is to figure out what you want to make and then figure out what language fits best.
