How do you make friends with React and FRP? 🤔 Start to develop your application using Focal.

This is a CFP for the ⚡️Lightning⚡️ talk at awesome ReactiveConf 2017. If you'd like to see this talk, please 🌟 star🌟 this summary and retweet my tweet 🙂 #ReactiveConf

Functional reactive programming (FRP) is very popular nowadays. The JavaScript community provides us with excellent tools like RxJS, Bacon, and Kefir. But, as we know, they have nothing to do with React. So how we can use the power of FRP in our React application? Using the correct state management, we can make friends with FRP and React and make our application truly reactive. In my lightning talk, I will talk about Focal

Create a Wi-Fi hotspot on Linux using `nmcli`

Original post : https://unix.stackexchange.com/a/310699

nmcli con add type wifi ifname wlan0 con-name Hostspot autoconnect yes ssid Hostspot
nmcli con modify Hostspot 802-11-wireless.mode ap 802-11-wireless.band bg ipv4.method shared
nmcli con modify Hostspot wifi-sec.key-mgmt wpa-psk
nmcli con modify Hostspot wifi-sec.psk "veryveryhardpassword1234"

Use yarn with Greenkeeper

When using yarn, it will create a yarn.lock lockfile which holds data on your used dependencies. This file also includes hard-typed versions, so should you update your dependencies, the yarn.lock file is basically outdated and needs to be regenerated. While yarn does this automatically, Greenkeeper pull requests that update dependencies as of right now do not do this regeneration, which means you would have to do it manually.

This gist shows you a way how to automatise this step using a Travis CI script.

Prerequisites

You use Travis CI and have it build Pull Requests (default behaviour)
You have a yarn.lock file in your repository for Travis CI to automatically install yarn (yarn will be added to their default images soon)

Legend:

require-from-twitter

Since Twitter doesn't have an edit button, it's a suitable host for JavaScript modules.

How to use

const leftPad = await requireFromTwitter('712799807073419264');

It can be difficult to test the different scenarious for a module intended for use by including in another class.

If the class is statically defined in the spec, any later definitions extend, not replace, the first definition - which can cause test issues and breaks isolation between examples.

RSpec.describe SomeModule do
  class SomeIncluder
    include SomeModule
  end
