Realtime data with MQTT, Node.js, MQTTClient.js and Socket.IO - Digits Domotica Blog
Seeing things happen the moment they actually do happen, that’s what I like the most. And that’s why I’ve always been searching for a better solution than Ajax. I use Ajax here and there on my own website (which is actually nothing more than a showcase of what you can do with Domotica/Home Automation), but I never really liked it. It always felt like some sort of patch-up while waiting for somethi
Full-stack Ruby: build a realtime web app with React.rb and Opal - RethinkDB
Opal is a transpiler that converts Ruby code into browser-friendly JavaScript, opening the door for developers to build frontend web applications with Ruby. It’s a particularly intriguing option for backend Ruby developers who want to use the same language across their entire stack. I recently gave Opal a try myself, incorporating it into a simple realtime todo list demo that I built with RethinkD

Raspberry Pi and realtime, low-latency audio [Linux-Sound]
The Raspberry Pi can be set up to handle realtime, low-latency audio but it requires quite some tweaking. Hence this Wiki article in which some common bottlenecks as well as some possible optimizations will be described. Last but not least this article will explain how to get JACK aka jackd running on your RPi. If you use the micro-USB power input to power the RPi you might encounter sudden reboot

WebRTCのシグナリングにFirebase Realtime Databaseを使ってP2P通信をしてみた - Qiita

I created http://madebyevan.com/webgl-water/ back in 2011 and I’ve always been meaning to explain how it works. The most interesting aspect of the demo in my opinion is my approach to rendering caustics. The term “caustic” refers to the pattern that light makes when it is reflected or refracted by a curved surface. Caustics look like this: Caustics from the sun on the pool floorThis is normally be

主人公が絵の中心にいないのだ。 背景を美しくみせるための、添え物に過ぎない。 絵に人間賛歌がないから、あんなに練られたストーリーも、セリフも、一つの作品としてまとまらないのだ。 正確には、背景を美しくみせるというのもちょっと違う。 あの映画の絵では、背景ですら、光を、風を、雨を、それを表現するための手段にすぎない。 人物が映るシーンは逆光で、人物は平面的に沈んでる。 見えないほど雨が画面を曇らせる。 風に草木がそよぐ端っこに人物がいる。 画面の半分が空。 思い出したのは、歌川広重だった。
