This is very welcome, as I've often found the official NASA/USGS tools to be difficult to use in practice. One thing that I don't understand is why coverage appears to be poor or non-existant at high latitudes (say, above 70

I actually met an ice cutter fairly recently. He made a sizeable portion of his living hacking off chunks of icebergs from tidewater glaciers for fancy cocktails. He sold the ice to upscale Anchorage hotels and bars.

I believe that's essentially what Cython allows you to do, by way of C. Since the Cython compiler isn't especially advanced, it requires some hints to get good performance, which is why Cython code is usually typed, structured mor

I think the point is that it special-cases the first object, at least in the syntax. You _could_ write it that way, but since the method is chosen based on all the object types, it doesn't make much sense to do so.

This is excellent news. Without knowing much clojure or looking deeply into the source, I wonder if or how this project does or plans to handle projections and coordinate systems? I find this capability to be among the really important thin

You mean like ripples in a pond? Yes, that does happen for both deep and shallow water waves. And yes, the wave power would be expected to spread laterally, causing the amplitudes observed at a point to be smaller further from the source. H

Imagine that you're learning your first programming language. You don't read Hacker News, and you can't imagine why having curly braces on a keyboard is more useful than a snowman character. Then, getting a working conditiona

I lived in urban Vancouver on less than that for years. It wasn't pleasant, but food and housing were never a serious problem. Although, if I had had dependents, I would have needed more.

Wouldn't confirmation and welcome emails fall under "implied consent"? http://www.crtc.gc.ca/eng/com500/infograph3.htm Seems like update emails might too, depending on the circumstances.

I would be very interested to hear what you think might have benefitted from the experiences of LightTable. Are they things you think could evolve convergently in the future, or are they mutually exclusive design choices?

That might lead to a backwards incompatible symbol clash with `numpy.dot`, `scipy.sparse.csr_matrix.dot`, user code, etc.

I wish that were true. I'm sure it depends on the field, but in my experience (more physics/natural science), MATLAB still leads for interactive scientific programming. I think Python is at this point recognized as a legitimate al

Although that may be true, I didn't really read the article as saying that OOP is bad, just that it brings a lot of extra baggage that newcomers to programming needn't worry about. Certainly as they begin to write more advanced pr

Agree with the above. In addition, all of these higher level languages popular in science seem to have pretty good support for calling existing C/Fortran libs when necessary. Julia is no exception, which makes it possible to take advan

Nah - use whatever tools you enjoy. This assignment doesn't look particularly numerically-demanding, and it looks like Ruby handles it fine.

I have a python GUI app. When I press a button, it probably takes a few tens of milliseconds to chew on it. I suspect it could be done faster with other tools, but I doubt I'd notice it. As for the actual work being done behind the GUI

This is true. Ah ha! Much more detail here: http://www.sciencemag.org/content/341/6149/997.full Seems that in some parts of the upper canyon, the ice configuration likely leads water away, but in the lower pa

I wonder how much this new map will effect model predictions of ice velocity and dynamic mass balance. Ice thickness measurements are important for calculating the stresses required to model ice velocity, and these are in turn relevant to p

Although that might be true in a roundabout way, I don't think that all models are required to be directly prognostic. Models can be useful without having much predictive power if they nevertheless lend insights into how different conc

I think grad students make an obvious target audience. They both write a lot of code, and (often) have freedom to choose their tools. My impression is that that's where much of the original momentum for Python in the scientific communi

Lighter isotopes preferentially get deposited on and form the ice sheets, so increases in ocean d18O correlate with glaciations.
