The introduction to Reactive Programming you've been missing

This tutorial as a series of videos

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Crystal vs Node.js Websocket Benchmark

Crystal 0.9.1 with Kemal

require "kemal"

ws "/" do |socket|
  socket.on_message do |message|
 end

To site a working example, we have built a streaming layout service which composes the page from multiple endpoints(microservices).

<html>
<head>
    <fragment src="http://assets.domain.com" inline>
</head>
<body>
    <fragment src="http://header.domain.com">
    <fragment src="http://content.domain.com" primary>

Comprehensions in Python the Jedi way

by Bjørn Friese

Beautiful is better than ugly. Explicit is better than implicit.

-- The Zen of Python

I frequently deal with collections of things in the programs I write. Collections of droids, jedis, planets, lightsabers, starfighters, etc. When programming in Python, these collections of things are usually represented as lists, sets and dictionaries. Oftentimes, what I want to do with collections is to transform them in various ways. Comprehensions is a powerful syntax for doing just that. I use them extensively, and it's one of the things that keep me coming back to Python. Let me show you a few examples of the incredible usefulness of comprehensions.

Nedir?

Creative coding (yaratıcı programlama) işlevsel olmasından çok yaratıcılığı ön plana çıkarmak için bilgisayar programları yazma işine verilen isimdir. Ortaya çıkan sonuçlar işitsel, görsel ya da başka herhangi bir formda olabilir.

Otomat, sürekli CRUD uygulamalar yapmaktan sıkılmış geliştiriciler olarak birlikte çok ilginç projeler geliştireceğimiz bir hackathon/creative coding partisi. 19-20 Kasım tarihlerinde (gece dahil) bir araya gelerek çok güzel görsel/işitsel ürünler üretip, çok güzel sohbetler edeceğiz.

Neler yapacağız?

Ne yapmak istiyorsanız! Yapılacak şey ve konu üzerine herhangi bir sınırlandırmamız yok. Ama etkinlik günü söyleyeceğimiz bazı teknik sınırlandırmalarımız olacak :) Bireysel olarak ya da grup olarak katılımak konusunda serbestsiniz. Hatta en güzeli herkesle yardımlaşmanız :)
