I would love to have a FPGA that i could drop inside my DX7 and replaced the OPS operator IC for a more advanced (more nuanced sound, purer sine waves) version !

Just in case somebody wants to know what is a DX7... The DX7 was the first affordable fully digital synthesizer on the market. It appeared in 1983 in a world of mostly-analog synthesizers that had polyphony limited to 8 voices (at hugely

Congratulations to you and your team for inventing what i'd call Neural Network Trolling (NNT), and thus giving us humans a way to escape the tyranny of automated decision systems. The consequences for the future can be enormous, serio

TL;DR: 1. Lumo runs ClojureScript without the need for a JVM. It relies on Node.js and Google V8. 2. ClojureScript compiler is self-hosted, thus: 3. Now you can compile ClojureScript without the need for a JVM. As a bonus, enjoy shorter sta

No, i'm not wanting to raise a language war; i just want to point out which direction Clojure should follow to keep improving.

by flavio81 9y ago
I agree with you (and i'm surprised at people downvoting my post). Thus, i repeat: Clojure is an excellent (and for me, preferred) alternative to Java on the JVM. However i would have liked to see it progressing into a language where y

I never said Clojure wasn't productive, i'm pointing out that it is too tied to the underlying platform. ClojureScript is an excellent replacement for Javascript, however code is not 100% compatible between Clojure and ClojureScri

Scheme is good, easy to learn and flexible; don't get me wrong: i just wanted to remark that it isn't very portable. It isn't difficult to jump from Scheme to Lisp and viceversa; they are similar in many aspects. If you want

This is the best HN post i've read today. You should expand it into a blog post. I also agree - context and state are important and useful, because many real-life problems or processes rely on such a model and thus translate naturally

Yes, they exist and have been used for decades; two well known examples are Common Lisp and Scheme. For example you can do functional, imperative and OO programming in Common Lisp, and it brings extensive features for working in all these t
