I would like some help on a small(?) pyparsing project for a prostate cancer research project I'm doing. First try and some test cases here.

https://github.com/2grep/CoPATH-Parser

What's in it for you?

1) Tell your Movember buddies you're actually working on prostate cancer research

2) Maybe a trip to SD (big maybe, but hey)

3) a chance to make some connections. For example, I'm getting some help on the postgres side from Joe Conway (has a postgresql commit bit, and author of PL/R, http://www.joeconway.com/)

At work I create a lot of flowcharts, e.g. http://www.freshfreestuff.net/wp-content/uploads/2008/05/gli... . I usually use Gliffy or UMLet. The problem is, all of these have drag-and-drop interfaces where you have to use the mouse all the time-and moving back and forth from the mouse to keyboard is painful for me. It also means that making flowcharts takes much longer than necessary-it would be really useful to have…

you should look into graphviz, this article posted a few weeks ago comes to mind: http://robrhinehart.com/?p=119

At first glance that sounds like exactly what I need! I'll definitely take a close look.

I'd pay $20/year if you build a reliable HN e-mail comment gateway. I'd pay double if you convinced PG to let your app sync people's comment history. Use e.g. Gmail OAuth IMAP authentication, sync to a label, optionally sync bidirectionally (i.e. comment replies from Gmail), but that's only marginally more useful than getting e-mail archives of comments here. Hell, if you write it in Python then I'll even donate the…

So, you want replies to your comments sent to you via email? or something more?

Curve matching in javascript. Take a list of data points (x,y) and creates an equation that offers the best fit. Side question: you will be making the code open source right?

This is a mischaracterization what curve-fitting algorithms do. You generally have to pick the function you want to fit, and then it's parameters are varied to minimize some comparison function. This means that this function would need to take the data, a chosen function, and a comparison function to minimize.

Also, this is a pure JavaScript project, and the OP wants to do something with HTML/CSS/etc.

Literally just poll this single page: http://news.ycombinator.com/threads?id=forgotusername once every 30 minutes, extract the thread structure, generate some message IDs, and keep a database of which message IDs have already been e-mailed.

The ability to reply is more complicated and probably less useful.

Do I need to create the function I want to fit? Or would I have to look for a function that looks 'similar' to a plot of my data? So say my data 'looks' like a cubic function, I would need to supply it a blank(missing the coefficients) cubic function?

Also thank you for clearing up the mischaracterization.

Could you explain what work do you need done?
