<div dir="ltr"><p style="margin:0px;color:rgb(0,0,0);font-family:'Times New Roman';font-size:medium">I am happy to announce the result of 3 months working on the GSoC project: "Communicating with mobile devices". After reading many documentation, looking for a good abstraction, learning about mobile apps and networks connections, and really valuable recommendations from my mentor, (I really want to thank Michael Snoyman for his availability and kindness) I succeeded in developing 3 libraries to make it easy to send push notifications to mobile devices. They are available on Hackage:</p>

The advantage of this notifications is that you can receive information from server when it is available without needing to continually poll. So, I started to think about a multiplayers game. Every time a player does something, you let the rest know about the new movement. So, I ran into the board game: "Connect 4".</font></p>
