I had a TI-85, and because it only had 2D plotting while the TI-89 had 3D plotting, I decided to write my own 3D plotting program. I allowed the user to input a 3D equation, and then it would draw a mesh using trig to project it from isome

There was a very good article explaining this using MATLAB, but I can't find it right now. This one is pretty close and explains the concepts of overflow, underflow, etc. The diagrams about "eps" are pretty good, even if y

That is a very helpful primer. What resources did you use to learn that level of understanding in TensorFlow? Just the codebase? If you have any other articles or references to recommend, please do so. Thanks!

It wasn't an abort, but the Mercury-Redstone 1 had a "T-plus" stop time [0]. It attempted to launch and the engine shut down immediately after lift off. It didn't explode, the escape rocket jettisoned, the capsule depl

To my knowledge, it only works with dataframes, has limited algorithms, and results in non-portable models due to vendor lock-in. That said, it makes ML easier for the non-programmer, is seeing fast growth due to MS investment, and can be

Not claiming to be the fastest, but here are two Python solutions suggested by Dave Beazley [0], plus one I extended using compiled regular expressions: # string replacement s = ' hello world \n' s.replace(' &#

I asked my 3-year-old how old she would be when landed in a rocket, and she said, "Um, 6?". Pretty optimistic.

The last part can be simplified to this: thors = thor() szs = flatten(map(list, map(sz, thors))) gdxis = flatten(map(list, map(gdxi, szs))) etis = flatten(map(list, map(eti, gdxis))) amupis = flatten(map(list, map(amup

Here's a generator version. It is not as terse, but seems to run faster. [Edit:] Or not faster in entirety, but finds solution more quickly during the iteration. from fractions import Fraction as F def thor(): for

Lyons' book is more thorough and complete, each chapter builds on the foundation of the prior ones. He aimed for a hands-on approach, not theoretical. It is very suitable for someone who isn't intimidated by math (of which there

Too bad there are more comments about the format of the discovery, than the actual discovery. I gathered that this is not actually the first time a ghost shark was caught on camera, but the first time it was filmed in its natural habitat.

How does the data get efficiently moved to the spun up cloud nodes? The article mentions parceling out jobs to nodes with independent storage, but how does that help data-intensive work? Are they doing something besides just copying data

Yes, in fact per Mark Adler [0] you'd use a Jupiter flyby to fly back to the sun and then do a high thrust burn at closest approach to maximize your speed into interstellar space (Oberth effect). [0] https://www.quora.com&
