rubenstein atrium at lincoln center. they're associated with a whichcraft, so you can get food/beer/coffee there if you want, there is wifi, but it's a public space so you don't have to buy stuff if you don't want to.

There's a big spread, and it depends on which institution and where in the institution you are. the closer you are to the money (front office vs back) the more money you make, but the more stress you get the smaller the firm, the more freed

We already moved to flowdock, it seems better so far, primarily because it's STABLE! When I used grove, the web client was basically unuseable, and even our IRC clients got disconnected periodically. The worse part is, the IRC disconnect

If you're interested in working with data (especially with python) you should come to this conference. Several of the authors of the major libraries in this space (numpy, scipy, pandas, pytables) will be there giving tutorials.

very sad - I will be donating. I would not be doing what I am doing today without matplotlib - a scientific computing toolchain without a good visualization component is a non-starter.

this discussion started about sharing with non-emacs and non-developers. Git is not feasible for non-developers.

There are a number of reasons, the dominant one being, sharing my outlines with other non-emacs users, especially non programmers.

Are you using clone in a negative way? I don't think workflowy has a lock on outlines, One could say that workflowy is just an emacs org mode clone except on the web

well theoretically, as the more apps come in, more users will join, so there will be more wealth to be spread around. Though - I don't see myself paying for a social network ever.

xlloop works for a bunch of languages, python, ruby, etc... But as far as i remember, xlloop is more of an RPC facility.

doing a scatter plot of 10k points in SVG is impractical - ok, so you could argue that you can't really see 10k points on the screen, that's fair, but if a user has 10k points, and they want to see them, you either have to figure out how to

I tried, if you ever nest svg it doesn't really work. If you don't do that, you might be ok.

just a small nitpick, you should be able to calculate portfolio variance using simple matrix operations instead of writing a double for loop. something like. temp = a* std_dev var = np.dot(np.dot(temp.T, cor), temp)

backbone has very little magic in it - and the particular confusing aspect mentioned in this post has to do with ubinding events by calling .html, which has nothing to do with backbone, that's all jquery.

If you have alot of data, and network IO is a big issue, you'll want to use something like hadoop (or disco) becuase they come with an integrated distributed file system and they preserve data locality. If you don't have that much data, M

I'm all in favor of better python interfaces for excel, but you need a better example, computing rolling time series statistics, and visualizing them? That's a job for pandas. If you want excel as the front end (I understand why you would

What I mean is that projects like coffeescript, and spine.js build classical inheritance patterns on top of JS and they work rather well. I'm looking for someone to contrast either a classical inheritance system built on top of JS prototype

I don't think that's the issue, though I did come to JS from a python background, so that that for what it's worth. For me the problem is that people tend to use prototypal inheritance to implement class inheritance patterns, but there are
