Ask HN: What are you working on?

currently working on SWIX http://www.swixhq.com

We are a social media metrics company and we just entered public beta.

Unfortunately, no. I've been getting the plumbing together; a layer that abstracts the ajax and session stuff so that all I'm left with on the server side is a file descriptor (one per session) to read from and write to.

I have some JavaScript code that allows you to select "units" (I made some ugly debugging sprites in Gimp) and move around with them, and scroll around and stuff like that. But I have yet to bridge it with the mostly to-be-implemented server-side logic. The client-side part is just for "dead reckoning" and generally making things flow between game state updates from the server. So both sides will share some logic, and I'm still thinking about how to centralize this.

It might take me as much as half a year to get unit movement working across the network; once that is in place, the rest should be relatively easy.

Luckily it's all hobby. ;)

Some great projects in here, I'd love to see a thread like this more often.

I'm working on a new eCommerce shopping cart - IONCart. Check everything out at GitHub - http://github.com/leftnode/ION-Cart or on my blog - http://leftnode.com/category/ioncart/

I want to release the minimum viable product as soon as possible, which will be open source, or you can pay for it and get all future commercial releases for free.

It's related, yes. Both are classified as "Humanitarian FOSS Projects" and Sahana has been worked on in previous years by people participating in the HFOSS Project summer internship, which is where we started Collabbit.

I'm not intimately familiar with Sahana, but from what I understand it's a fairly large system and can do a lot of specific things. Consequently, most of its deployments have been at sites of major disasters or for very large agencies.

Collabbit takes a different approach. Our goal is to facilitate communication inside groups and between groups, rather than to provide a means of accomplishing specific tasks. That means that Collabbit is quite simple and broad right now. While our initial use case was volunteer organizations communicating in New York City, we're hoping it can be a valuable tool for smaller groups as well.
