Support BCI in Clojure –- Help us bring Brain Pong to reClojure!

Hi Clojurians, I am trying to build Brain Pong — a game controlled entirely by brainwaves using OpenBCI and Clojure/Script. Yep, no hands — just thoughts. This project is more than a demo - it's the beginning of an open Clojure-based BCI (brain-computer interface) API for the whole community

Re: Macro help/strategy for writing a tiny DSL for circuit-model quantum computing?

My general advice would be not to start with macros. 1. Start with data - what are the entities (bits? gates?), and how do you represent them? It's ok (actually better) for these to be verbose. Plan for extension (maps are open, which is why they're so common in representing data in Clojure).

The problem isn't the macro, it's your use of syntax quoting. `(= x y) gets expanded at read-time into `(clojure.core/= x y)`. Not much you can do about that. Although I'd suggest perhaps changing your code a bit to not require macros. deftest mostly just creates a defn with some extra metadata an

Help me understand what part of this code is slow, and how to make it faster?

sure if any of these things should really impact performance that much though. And what I could do in Clojure if I wanted to improve it. Any Help? Thanks. -- You received this message because you are subscribed to the Google Groups "Clojure" group. To post to this group, send email to clo

Cool library! But i just changed to fipp this morning. I think I will try it much later. fipp is really fast that it succeeded clojure.pprint/write. On Mon, Oct 24, 2016 at 4:36 PM Thomas Heller wrote: > Try https://github.com/weavejester/cljfmt > > It is specifically written for clj code and no

Re: need help on `pprint/write` code with better readability

Try https://github.com/weavejester/cljfmt It is specifically written for clj code and not general pprinter. /thomas On Sunday, October 23, 2016 at 1:28:23 PM UTC+2, Jiyin Yiyong wrote: > > I'm using `write` function to generate code very heavily. But small part > of the code are hard to read.

What does miser-width mean since you set it to 60? On Mon, Oct 24, 2016 at 3:08 AM Alex Miller wrote: > Try something like this: > > (require '[clojure.pprint :as pprint]) > (defn print-code [o] > (binding [pprint/*print-right-margin* 100 > pprint/*print-miser-width* 60] > (ppr

need help on `pprint/write` code with better readability

I'm using `write` function to generate code very heavily. But small part of the code are hard to read. So I digged into the options and increased `right-margin` to make it a little better. Here's the changes: https://github.com/Cirru/sepal.clj/commit/e65e2d3cac8a5c5537716acd12cc475712ab6f66 htt

Looking to develop an app to help Live Streamers (Twitch, Facebook Live ...) interact with their viewers.

Hi, I'm developing with clojure/clojurescript since 3 years and I'm currently looking to create an app to help live streamers (Twitch, Facebook live, Periscope, YouTube, HitBox etc ...) interact with their viewers. Right now, the only way to interact is using the chat. Really quickly

Thanks Zach, I would love to do an unfair comparison between clojure and nodejs :) Gonna give it a spin On Tuesday, February 23, 2016 at 5:09:50 PM UTC, Zach Tellman wrote: > > For what it's worth, Aleph will handle pipelined requests in parallel: > https://github.com/ztellman/aleph. > > On Tue

Re: [Help] core.async and jetty

Hi Miguel- pipelining is essentially http keep alive. A very old jetty thread http://jetty.4.x6.nabble.com/HTTP-1-1-Request-Pipelining-handling-td18682.html indicates that for simplicity jetty will execute subsequent requests on the kept-alive socket serially. Jonah On Mon, Feb 22, 2016 at 3:3

Re: [Help] core.async and jetty

By the way, I can see that jetty is reusing the same HttpInput instance on the request (most probably because of pipelining) On Monday, February 22, 2016 at 8:33:37 PM UTC, Miguel Ping wrote: > > Hi guys, > > I'm trying to replicate an experiment on nodejs and http pipelining: > http://blog.yld.
