HN discussionI recently published a series of 16 blog posts Deep Learning from Scratch to GPU that does exactly that! [0] I also started working on a book titled "Deep Learning for Programmers"[1] that takes it even further! You can subscribe today and start reading the drafts as they are written.

HN discussionIn my experience, it works just fine. Clojure for the frontend is the best-in-class frontend dev environment that I've worked with. Instant hot code reloading, a browser-connected repl, great debugging tools, and a really nice collection of libraries for getting stuff done. I've never had to use native APIs for iOS and Android, so I can't speak to that from experience, but I know that there's some really nice machin…

HN discussionMay I plug-in with ClojureCUDA, a high-level library that lets you write CUDA with almost no overhead, but write it in the interactive Clojure REPL. https://github.com/uncomplicate/clojurecuda There's also tons of free tutorials at https://dragan.rocks And a few books! (not free) at https://aiprobook.com Everything from scratch, interactive, line-by-line, and each line is executed in the live REPL.

HN discussionI would think Clojure vs. Java would be used given immutability. I like both Haskell and Racket for math, especially this article on geometric algebra with Haskell: https://crypto.stanford.edu/~blynn/haskell/ga.html I am personally learning Shen[1] because Lisp, optional typing (great type system), and the formal work done within it, and for it in proving, verification and other related endeavors. It seems to tick t…

HN discussionYou might find my Clojure Linear Algebra Refresher helpful. http://dragan.rocks/articles/17/Clojure-Linear-Algebra-Refre... This is the link for the first part. You'll find further articles there. It walks you through the code, explain things briefly, and points you to the exact places in a good Linear Algebra with Application textbook where this is explained in detail.

HN discussionLet me chip in with some self-promotion. This book explains and executes every single line of code interactively, from low level operations to high-level networks that do everything automatically. The code is built on the state of the art performance operations of oneDNN (Intel, CPU) and cuDNN (CUDA, GPU). Very concise readable and understandable by humans. https://aiprobook.com/deep-learning-for-programmers/ Here's…

HN discussion> It's not Clojure-dead It never ceases to amaze me. Almost every single time, whenever there's a post or a comment on HN that mentions Clojure or Clojurescript, there's always someone from outside of the Clojure community attacking the language, saying things that are simply untrue. Like people are afraid of it becoming too successful. It's not some zero-sum game - the success of one language ecosystem doesn't mean…

HN discussionThe book looks interesting and the associated libraries (neanderthal for e.g.) But while going through your performance comparison [1], I feel something is off. I am not that familiar with libpython-clj and how it works, but looks like you are loading python from within the JVM and in turn the python is loading the C++/fortran OpenBLAS libraries to get the numerical calculations done for the Correlation Coefficient.…

HN discussionOh, so many things. The parallelism isn't actually that powerful, and in 2019 there's very little to set it apart. The building blocks are great, e.g. immutability everywhere, but few of the built-in primitives are actually usable (hidden unconfigurable thread pools etc). Stack traces still regularly horrible. Libraries are regularly abandoned. ClojureScript integrating with npm etc is more stress than you'd like. C…
