VirtualBox DHCP gives same IP address to different machines

Usually happens after cloning VMs and problem is because there is the same MAC address. Check virtual machine network settings and change as needed.

CanJS and ClojureScript

I don't really like compiled JavaScript languages, but if I had to choose - I like ClojureScript the most. It is big friends with Om MVC framework, which is based on React.js. React is another component framework like CanJS, but is too verbose to my tastes and has less features out of the box, so I like CanJS more. Only problem is that it does not have a lot of integration with ClojureScript. But it is pretty easy to solve, because ClojureScipt and CanJS are both amazing and flexible. There is example of simple component, there is ClojureScript:

(ns myexample
  (:require [domina :refer [by-id set-html!]]
            [domina.css :refer [sel]]))

(.extend can/Component
  #js {:tag "my-component"
       :scope #js {:value 3
                   :increment #(.attr % "value" (inc (.attr % "value")))}})

(set-html! (by-id "my-root") (can/view "my-template" {}))


  <div id="my-root"></div>
  <script type="text/mustache" id="my-template">
      Value: {{value}} <input type="button" can-click="increment" value="Increment"/>
  <script src=""></script>
  <script src=""></script>
  <script src="base.js" type="text/javascript"></script>
  <script src="myexample.js" type="text/javascript"></script>
  <script type="text/javascript">goog.require("myexample");</script>
