I'm developing Computer Aided Manufacturing system in the browser (chrome Application for the USB connexion). And I developed the embedded code for the controller too. https://github.com/nraynaud/webgcode http://nraynaud.github.io/webgcode/ (for a taste of g-code)

last week I worked on some pocketing and lettering code : http://nraynaud.github.io/webgcode/text.html (it's a excuse to introduce Ember into the codebase and learn it). The display is multi Level Of Details (it's visible when scrolling quickly), and the computation is done with a worker pool.

I'm working on a knowledge graph + NLP interface. http://i.imgur.com/r10Yn8v.png

This is really cool! Are you building it from scratch or is there some existing knowledge graph you're building on top of?

A World Cup betting app, to play among friends! Built with NodeJS (backend), Firebase (real-time chat), and Meteor (front). http://i.imgur.com/79zO1YZ.png

Out of interest, how are you getting your data changes at the NodeJS level to automatically propagate to the Meteor clients? Or by "NodeJS" do you mean you're using the full Meteor stack?

Not a screenshot, but a js mockup of a new service I am working on with a few others.

http://junk.arandomurl.com/

In PouchDB We have a client side database that syncs in real time / works offline etc, but getting the server side of it setup for application users is still a hassle, this is gonna be a service (and an open source app), that deals with users authentication and datatase provisioning.

I want to get it to the place where you pretty much just sign up, include some js into your app and your uses have offline capable real time syncing application, some what along the lines of firebase except with a more capable offline experience (and open source)

I read somewhere about 'the kernel trick' (a machine learning concept used in vector classification), and decided to implement a few major distances (euclidean, absolute and dot product) and see what they would actually look like.

Here are 100 cases of the Iris dataset in a 'euclidean kernel': https://twitter.com/adrnsly/status/455305310488363008/photo/...

Turns out 'the kernel trick' and KNN classifiers can be chained endlessly in a recursive structure (as long as you build and propagate your neighbourhoods right!), which means they can be used as an activation system in a neural network (as opposed to the sigmoid or hypertan functions).

Just so you know, you have a name conflict with another open source project of an entirely different domain[1]. This may or may not matter to you.
