Insanity is doing the same thing over and over again and expecting different results. — Michael Scott

Be insane if absolutely necessary.

May 13	comment	How can I use the overhang argument to Partition to avoid using PadLeft and PadRight here? Thanks, voted :)
May 12	comment	How can I use the overhang argument to Partition to avoid using PadLeft and PadRight here? But Andy explicitly says that he doesn't want to zero pad for other reasons — "The reason I don't just use this solution is because ultimately I don't want the zeros, I will be working with a ragged array. If I can get the overhang argument right I can just use {} for padding saving me from post processing the zeros." So if you're comparing performance with the other solutions, you should also account for whatever time (and additional code complexity) that post processing takes.

May 12	comment	How to type function terms into metric? @belisarius Ok, I'll ask and answer tomorrow on meta. I need to get some sleep tonight.
May 12	comment	How to type function terms into metric? 4) Try to reduce your problem to a minimal example that illustrates the issue. It's easier to read and debug a 10 line program than a 50-100 line monster. 5) If you're basing your expressions on a mathematical formula, then please also provide a link to the paper/website/other reference for the formula, unless it is obvious to all what you're referring to (still, a link won't hurt). Often, the name is sufficient as an identifier, but for certain prolific scientists (e.g. Newton),"X's equation" can mean different things to different people, depending the specific field.
May 12	comment	How to type function terms into metric? 2) Do not use heavily typeset expressions (subscript/superscript/etc.), as they are ugly to look at here, cannot be easily parsed without Mathmatica (sometimes a lot of us give hints/identify the problem by simply looking at the code, which is not possible here). Also, it is very likely that there will be copy-paste errors, so avoiding them altogether is good (the only exception is when your question is about typesetting quirks). 3) Do not use unicode/Chinese input for variables/function names. Most of us have no idea how to input them or what they mean or which function is which. [2/3]
May 12	comment	How to type function terms into metric? @hjq1990 A few pointers to help you with editing/formatting code here — 1) Because of the `In` and `Out` labels, we can't directly copy paste your code, and people are less likely to take the time to strip them out manually themselves. The widely accepted practice is to remove all the `In[...]` labels and comment out all the output so that they don't evaluate. Also, include only that output which is actually relevant to the problem (we don't need the output of initializing 10 variables, for instance). (continued... [1/3])

May 11	comment	Open-source IntelliJIDEA plugin to support Mathematica development @b.gatessucks I guess one way would be to become an expert at java and pitch in, so that halirutan is not overwhelmed by the task at hand :)
May 11	comment	Track object movement @rafiki It was a little tongue-in-cheek... While it is true that particle filters are very useful in real world tracking applications (see this video of the man with a glowing butt, for an example), it is overkill for the application you suggest. Something like what SEngstrom suggested (extract coordinates of interest) is what I would do as well.
May 11	comment	Track object movement You could always use a particle filter... :D

May 11	comment	How do I draw a hemisphere? @J.M. Yes, they all give a blank image. The perturbation works though, except for `"Butt"`, which gives a blank image.
May 11	comment	Simulating a Stochastic Process within certain bounds @Amatya `%` is the previous input, `%%` 2 inputs prior, `%n` n inputs prior (all, as indicated by the `In[n]` and not by your current position)
