Moving off of Matlab for numeric/image processing
Reardon abused me (not really) for still using Matlab and goaded me to look into the ImageJ world. So I am learning. Seems like I need to get smart on
- ImageJ and the Fiji distribution
- Python derivatives like Jython for ImageJ scripting and NumPy/SciPy for numeric/array processing
- There are a ton of other scripting language choices but seems like python covers this well enough. I don’t want the brain damage of Clojure.
Other stuff to learn? I’ll have to pick up an editor and source management tool as well. The benefit of all this? Any code I write should be faster, more easily redistributable, and there is a large support community. The disadvantage? I have to assemble all these piece-parts to get something equivalent to MatLab, so more time d&*king around with software which is time taken away from research focus. And the Matlab universe has a pretty good support community too, so not clear I am trading up there. Certainly the ImageJ/Jython/NumPy path is “cooler” along a certain dimension, but do I care?
Online math resources
Just discovered Cramster. Awesome. If they have coverage for the text used in your class, this is super helpful.
Finding that Wolfram Alpha is also becoming more useful. Easier to run to it to figure out the integral of x^2 sinx sinhx than spinning up mathematica or maple or matlab.
Grabbag of interesting articles on math, econ, science, design, web
No theme here other than “stuff I happened across recently”
- Terry Tao math blog. Brain stretching.
- How Goldman profited on housing crash. Don’t know how reliable this source is but disturbing.
- Controversy about whether there is or is not a giant magma chamber under the state of Washington. Probably not but a great disaster movie in the making.
- Thread on design versus iteration.
- Automated sports writing. Amazingly readable. (Thanks Phil).
- The Billion Dollar Gram. Another one via Phil.
- Gravitational Corridors. Cool.
- Nowhere are we more honest than the search box.
- NASA dollars pissed away on 2012 nutballs
- Why it is harder than ever to get into some colleges. Interesting question about whether this applies to other markets.
Linear algebra, finite element analysis online
Reardon recommends Computational Science and Engineering. OCW links.
Tensors and Index Notation
A couple of good primers out on the net:
- A Primer on Index Notation from Colorado Civil Engineering. Practical intro to index notation
- A Primer on Index Notation from MIT. A little more theoretical and discussion of use in calculus.
Somehow I did not ever learn about index notation in my past educational life. Time to learn.
