Trello Tech Stack

Recently been reading about the Architecture behind Trello. The application design is quite simple and straightforward.

Client : 

• Backbone.js (client-side MVC)
• HTML5 pushState
• Mustache (templating language)

Pushing & Polling :

• Socket.io & Websockets
• AJAX Polling
• Redis
• MongoDB

Server :

• node.js
• HAProxy
• Redis
• MongoDB

Experience with node.js :

We've been playing with a node.js based stack: RailwayJS & MongoDB, for creating a web admin. The main goal was to use an open source framework for CRUD generation. We finally managed a quick & dirty admin setup  for managing site-wide seed data.

Now that I've seen what can be done with node.js, we probably should have explored developing the whole application using a mix of node.js.

Userland Frontier

Happened to search about an end-of-life weblog software: Userland Frontier, while browsing through Joelonsoftware.com's About page.

His reference to the use of Frontier as his weblog in the initial days led me down memory lane and it seems that the product has been GPLed since 2004 as described on their Wikipedia page.

I remember trying out Frontier as a trial software for windows 97 during 2003. Plan to try it out on my MacBookPro in 2012 , almost 8 years later. It could be a great tool to keep track of documents on my local server.

The Opensource releases of Frontier are uploaded at frontierkernel.org. The last update on their sourceforge page is about a year a go.

I would have presumed some one would have forked and re-forked the project multiple times if the original project has been offered to opensource domain.
