Testing ephp

To test how can works ephp I do a escriptize and you can use it to execute simple php code:

git clone https://github.com/bragful/ephp
cd ephp
make

IM Binary & SSL secured

All the time I was working with XMPP I realized this protocol has a lot of flaws to use in mobile devices, even the lack of sync for the messages between several devices. This protocol tries to solve those flaws:

1. Use of bandwidth. This protocol is binary and use keywords to save a lof of bandwidth using the same protocol and the same featureas as XMPP.
2. Reliability of the messages. Using ACKs in every sent ensure all of the messages will arrive to the destin and in the same order. The protocol is async, but for messages the server must to use a pipeline sent.
3. Multi-device. Capabilities to ensure the messages are delivered on all the devices the user has registered.
4. Security. Ensuring a certificate is valid between client and server (client must to check server certificate and server must to check client certificate) ensure the communication should be more secure.

More Testing ephp

To continue testing ephp with the new features I release, first we need a fresh ephp version:

git clone https://github.com/altenwald/ephp

defmodule AdjacentCells do
  @moduledoc """
  This module is a way to search, mark and count the adjacent cells based on
  the post published by Kevin Ghadyani originally in JavaScript and showing
  that using Elixir the code could be simpler and powerful.

  https://medium.com/free-code-camp/bet-you-cant-solve-this-google-interview-question-4a6e5a4dc8ee

  Indeed, the original code run by Kevin is spending in the better case 229 ms
  with 3 random colors and more than 1 second with only one color.

Check local links, if there is a broken link the compilation fails.

You can configure the kind of URLs to avoid to check. For example, if you
want to avoid check dependencies like PDF or images:

[links]
exclude_uris = [
