Upon exporting my character in blender as fbx it rotates by -90.  The question linked has not fixed my problem. :|  I have already applied transform, rotation, and scale. This happens in blender right after i export and it brings me back to the 3D view.  The character used to export normally, until i recently rechecked some animations and edited the bones.
I have had no problems exporting .fbx files for Unity except recently some of my .fbx started to rotate the mesh. The asset is correctly oriented, but the mesh is rotated 90 degrees. Is there an explanation and fix for why this happens sometimes, and works properly otherwise?
Bibliography with page numbers In GKP's Concrete Mathematics, there is a useful and interesting feature I would like to see in more books. The bibliography entries include:   a - the page numbers where the book or article is cited in the document. b - a few lines of review of the cited work.   It is a kind of mix between bibliography, index and review.  Are there stable LaTeX packages/BibTeX styles to do (a) and (b) ?  EDIT: I wrote (b) initially as "comments about the work cited". It could be understood as "gathering comments made in the book about the work and reproducing them in the bibliography".  This is not what I meant but this could be something useful for others. Let $a_n$ be a sequence such that $\forall n\in \mathbb n: 0&lt;a\le a_n\le b &lt;\infty.$      Prove:          $\displaystyle\limsup_{n\to\infty}\frac 1 {a_n}=\frac 1 {\displaystyle\liminf_{n\to\infty}a_n}$   $\displaystyle\limsup_{n\to\infty}a_n\cdot \limsup_{n\to\infty}\frac 1 {a_n} \ge 1$ and there's an equality iff $a_n$ is converging.       Suppose there are two subsequences: $a_{n_l}, \ a_{n_k}$ such that $\lim a_{n_k} = k, \ \lim a_{n_l}=l$ and suppose $l\le k$, so $\lim \frac 1 {a_{n_k}}=\frac 1 k , \ \lim \frac 1 {a_{n_l}}=\frac 1 l$ so clearly: $\frac 1 k\le \frac 1 l\le l\le k$ so it's easy to see once the largest limit (supermum) is 'inverted' it has to become the smallest limit (infimum).   I realize this doesn't show equality, I don't know how to do the other way and I'm not even sure if what I did is good. If $a_n$ converges, suppose to $L$ as its limit then we have: $L\cdot \frac 1 L=1$.  If it does not converge then $a_n$ may tend to infinity or won't have a limit. From 1 we can change it to $\displaystyle\limsup_{n\to\infty}a_n\cdot \frac 1 {\displaystyle\liminf_{n\to\infty}a_n} \ge 1$ and from BW, every sequence has a converging subsequence, and since for converging subsequences: $\liminf a_n\le \limsup a_n$ we have $\frac {\limsup a_n} {\liminf a_n}=\limsup a_n\cdot \limsup\frac 1 {a_n} \ge 1$.   This should probably be in absolute value since one of those subsequnce limits can be negative, but it isn't in absolute value in the question. How to work with iAds using xcode 3.1.3 Shadows along edges of mesh in 3D View I have recently started using blender and one of the models I'm working on has dark shadows along edges. I started this model from scratch. I can't remember them being there when I first started the model, but I had trouble joining areas together and think I've pressed something I shouldn't have. However, there are so many options I'm not sure what I did.  Here is an image of what I mean   The one on the left has the shadow. As a test I started a new model, which is on the right in the image, and as you can see it doesn't have any shadows.  Also, occluded vertices partially show through the model. Occlusion doesn't work properly.   In orthogonal view small darkened triangles appear along the the edges.    I don't really want to start the model again from scratch so any ideas on how to remove this shadow would be great. Thanks. Does herd behavior influence the SO sites? Are you influenced by existing votes? That is, if a question or answer has a large number of up votes, are you more likely to vote it up (and similar for down)?  The reason I'm putting this question is this: on these sites we see how other people vote before we do. This almost certainly influences us (see resources, below) - just as we can be influenced by our  (people often naturally pick the busy one).  This trend may also be further influenced by rep - do we give more weight to the answer of someone with 10K rep than someone with 10 - even if they both have e.g. zero votes?  And if this does happen, is it even a problem?  I'm not looking here for solutions - right now I'm just curious as to whether this is something you recognise.  Clarification edit: I'm referring to voting here. Example: if you see a question or answer with 20 plus votes, are you more likely to vote it up than if it has no votes, or a negative number vote?  Bounty: I've been so impressed at the quality of answers and comments here that I'm offering a small bounty to encourage more great responses and discussion.  Wrapped up: Bounty awarded to the answer that received the most votes. In light of the question, it only seemed appropriate...  Resources: Complex numbers equation: $z^4 = -16$ Show bigger amplitude of physical pendulum means bigger period Suppose you have a physical .

After experimenting with Windows domains and domain controllers in a virtual environment, I've realized that having an active directory domain named identically to a DNS domain is bad idea (Meaning that having example.com as an Active Directory name is no good when we have the example.com domain name registered for use as our website).   , but I'm still not sure about what other rules there are around naming Active Directory domains.  Are there any best practices on what an Active Directory name should or shouldn't be? Merging folders with mv? Given a hotkey, how can I find which program owns it? Training on the full dataset after cross-validation? A book I once owned and read back in late-80's or early-90's that I have not been able to identify title &amp; author for:  It was a SF story concerning tiny native lifeforms, living on either a planetoid or possibly a dead/neutron star, that evolve at a seemingly accelerated time rate. Most of their story is told in the few days of observation (from orbit) by a human expedition to the planet, during which time-frame the race below progresses from stone-age tech level to being more advanced than the human observers, and eventually flying up to meet the humans in small advanced craft powered by micro-singularities... one of which accidentally 'disintegrates' the tip of a human scientist's nose in the process.

"NG NS" on ticket after airport security I went through security at the Sacramento Airport with a friend. He got something written on his boarding pass "NG NS". I didn't have that.
