   I totally hear you about 3. I was super shocked when I (North America educated) went to visit a university bookstore in Bulgaria. For around $5 I was able to buy a "Mathematical methods of physics" book that covered in 300 pages t

   I highly recommend Goodfellow et al.'s deep learning book: http://www.deeplearningbook.org/ Part 1 of the book has a nice introduction to machine learning concepts so it makes the book accessible even for people new to

   I have quite a few adult readers using my book to refresh and re-learn basic calculus and mechanics. You might consider checking it out[1]. It's not free, but very affordable. [1] https://www.amazon.com/dp/09920010

   I've been using this approach and it works amazingly well (for text-based formats like .tex and .md). I switched from mercurial to git because rebasing feels much more natural. I'm currently actively maintaining five different ver

   I wrote a math book that helps a lot with math de-fearing. The technology is very old-school: the printed word, but the teaching style is new. The tone is very conversational so it feels like you're reading a really long blog post. It&

   Seems like another version of `Fabric`, though the expect functionality is nice. After investing so much in learning the quirks and specifics of the fab command, I'd need a very compelling reason to switch.

    Yes .tex programming is probably the least intuitive kind of language I've ever seen. Here is a FizzBuzz in vanilla .tex for anyone who curious to see what that's like: % fizzbuzz.tex -- Compile with pdftex, not pdflatex

    This is pretty interesting. The paper basically starts by talking about "Concept maps", or graphs of concepts and relations. These concept maps correspond to an SQL schema, and instances of concepts and relations correspond to tab

    The conversation is about very advanced math topics (advanced undergraduate or graduate level). At some point in the levels of abstraction it becomes hard to show concrete applications of the ideas, or rather the applications of math is to

    Why not use `update` in Python? e.g. if you want to merge dictA and dictB, you'd write dictA.update(dictB) If you have many you can always use this: dictD = {} map(dictD.update, [dictA, dictB, dictC])

    Nice full example of a working vue.js app. For me it loads very fast, almost comparable to the text-only version. Where is the code that generates the screenshots? I looked around here https://github.com/vuejs/vue-hacke

    Is it possible to explain Noether's principle for momentum (translation invariance) or energy (time invariance) without going into Lagrangian/Hamiltonian mechanics? I really like Noether's principle, but every time I try to e

    Could you say a few more words about this book? It looks interesting, but I can't find a table of contents or a review of it. Is it intended for advanced mathematics, or can it be useful for basic math too?

    Very nice idea. What is the objective function (loss function) that `back_propagate` is optimizing exactly? I'm new to the world of NN, so really excited to see NN code that works from first principles. Reminds me of https:/&#x2F

    I think SISP is an awesome book, but I don't see why it has to be Scheme, at least for the first half of the book. Let's not be too dogmatic about our shovels. A shovel is a shovel. For example, here is SICP with examples using

    You're right. Of all the mainstream textbooks on subjects for first-year science, linear algebra textbooks are the best of them all. I guess the main "bullshit" I could reproach is the price tags, $60 -- $90, but even that is

    The book proves most things, just doesn't follow the standard math format of theorem-followed-by-proof. All the definitions are reasonably clear, and most of the proofs that are accessible and educational are given (e.g. the equivale

    nice... somewhat glitchy, but still pretty good. I doubt there is reinforcement learning going on though, I think the AIs of the mugen characters are hard coded.
