HN,

I am working on a few network analysis algorithms. However, I would like to run them on some real world data to see if anyone is actually interested in the results.

What do you get?

That's where you (hopefully) step in. If you supply me with your anonymized customer data, I will provide you with a report containing:

- Basic network statistics (found here: (http://en.wikipedia.org/wiki/Social_network_analysis))

- Clusters of related customers

- Pretty pictures of your data

- Some new analysis that you can't get from current graphing libraries

Contact

If that has piqued your interest, please get in touch with me the address in my profile.

Details

The one caveat is that I can only take a certain type of data. Namely, where your customers are connected in some way to other customers. This can be through:

- one customer referred the other

- both bought the same item / rented the same movie / etc.

- one follows the other on Twitter

- basically, anything from which I can create something like: http://en.wikipedia.org/wiki/File:Graph_betweenness.svg

(Also, you'll probably need > 50 entries to get anything significant in the report.)

If you aren't sure if your data complies, send me an email!

Dear HN,

I've been slowly going through tpacek's book list - but the learning process has been stifled. I find myself wanting to try out some of the techniques but I am hindered due to concerns about legality.

I realize one can use resources such as http://www.hackthissite.org/ and Stripe's CTF challenge, but are there other forms of resources for practicing web security?

HN,

In the past, I've been entirely a software programmer and haven't come close to the fence between software and hardware. However, I would now like to experiment with some ideas that would utilize a touch interface.

I shy away from utilizing an iPhone or a laptop's touchpad, though. Are there feasible ways to acquire a touch screen with USB connection - or is there a (relatively) cheap way to create a resistive touchscreen with little prior knowledge?

I've started reading: http://www.aosabook.org/en/distsys.html

And his first example is that of an image hosting website. My mind went on a bit of a tangent and I was curious...

Do image hosting sites keep a hash of their images and only store 1 copy of each image? I'm not sure the effort it would take to ensure there was a single copy of each image but... it seems like it would save some space.

Does anyone know?

Let's say I wanted to create a video game called Bonopoly. It would have Monopoly's game mechanics. Is this legal?

What if I changed the game board to a circle. Is this legal?

What if I changed the name to B!, changed the game board to a circle, and allowed you to go either way around the board. Is this legal?

Can someone draw a line in the sand for me? (Obviously, seek a lawyer and whatnot - but just as general advice...)

I'm looking for any good quality, open sourced Android applications making use of Fragments. Does anyone have any examples?

There was a post on here a few months ago about a man who quit his job and sought $x in y days starting anew.

Does anyone have the link to his blog / know if he continued on with it? I can't seem to find the correct search terms for the post.

Is there any software / website that will visualize an academic paper and its "children", and their "children", etc. as a tree-like structure (up to depth of x...)?

This would be remarkably helpful in learning a bit more about a niche topic.
