I'm looking for the title of a show I saw when I was a child. I'm not sure what year it was made, but it could have been anything before 2000, really. I remember some overall plot features and details about a few episodes.  Overall Plot: The main character was a white male, probably in his early 20s. There was also an old man, a woman who was also probably early 20s, and some sort of small alien creature that I don't believe spoke english. Together these people travelled to different dimensions/through space (I think) on a ship.  They were being persued by a black male, probably about 30-40s who wore some kind of red armoured suit. Initially you believe him to be the bad guy, but I think there was a reveal where it turned out he was the good guy and the old man was the bad guy.  The following are some episodes, or parts of episodes, that I vaguely remember:  1) An episode that featured a character that was a human sized rag doll, possibly raggedy anne? I believe there were multiple 'toy' people.  2) An episode where the woman ate a piece of mushroom she found, which then turned out to be part of a 'mushroom person' and she fell ill  3) At some point the guy in a red armoured suit got trapped on a desert planet and couldn't get up. He tricked some wild old woman into helping him up and then he escaped?    NOTE: I am a big scifi fan. I have seen all of the big tv shows like Dr Who, Sliders, Star Trek, Red Dwarf, etc. It is not one of them. It is not going to be a big show, I wouldn't be surprised if it's one of those shows that had like 10 episodes and then got cancelled. I saw this in England in the early 2000s, probably on the SciFi channel, but I have a feeling it was either American or Canadian made.  I read a lot of science fiction as well, so I'm pretty sure it's not some sort of adaption of a popular scifi novel, so it's probably either an original piece or adapted from a relativley obscure source.
I'm looking for a 90s (or early 2000s) scifi (mini)series where a boy and old man chase a black guy in metal suit. I think they were going through different dimensions. I remember part of it, but I don't think I ever saw how it ended. I remember my friend telling me there was a twist at the end. I think they were trying to find something and he was always ahead of them..
Volume of an n-simplex It's rather tedious to show using Fubini's Theorem and induction on $n$ that the volume of the region $x_1+x_2+...+x_n \leq 1$ with $x_1,...,x_n$ nonnegative is $\frac{1}{n!}$.  Is there an easier way to see this? $\sum_{n=-\infty}^{\infty}\frac{1}{(n+\alpha)^2}=\frac{\pi^2}{(\sin \pi \alpha)^2}$? How to create wifi hotspot in Ubuntu 17.10 Editing polygons simultaneously in ArcMap? I have two polygons:    How can I reshape both Polygon 1 and Polygon 2 at the same time?  Will the area of each polygon change automatically in the table after reshaping?  I'm using ArcMap 10.1. Assume that $A$ is an $n\times n$  real matrix, i.e. $$A^T=-A.$$  Since $\det(A-\lambda I)=\det(A^T-\lambda I)$, $A$ and $A^T$ have the same eigenvalues. On the other hand, $A^T$ and $-A$ also have the same eigenvalues. Thus if $\lambda$ is an eigenvalue of $A$, so is $-\lambda$. If $n$ is odd, $\lambda = 0 $ is an eigenvalue.  A curious search in Google returns  the nonzero eigenvalues of $A$ are all pure imaginary and thus are of the form $iλ_1, −iλ_1, iλ_2, −iλ_2,$ … where each of the $λ_k$ are real.   Here is my question:     How can I prove the fact that "the nonzero eigenvalues of $A$ are all pure imaginary"? How to tell Google that I have changed my website URLs? I have done major updates to my website, and renamed all my URLs.  How can I tell Google that I have renamed these URLs and let Google refresh its index?  My website URL: http://www.pndmasr.com/  My sitemap: http://www.pndmasr.com/sitemap.xml  I have uploaded my sitemap via Google Webmaster Tools many times.  However, every time I search Google for "pndmasr", I still get results with old pages. I have waited more than 3 days but the problem remains. Any suggestions?  Is there a problem with my sitemap? For some or other reason, typing @ᔕᖺᘎᕊ in a chat room pings everyone who's been in that chat room for the last 7 days...    Seems to work in all chat rooms (I only tested 2 as I don't want to upset too many people...)  How should we proceed? In bibliography, how to print the page in my text where I cited certain paper? How to get, for instance,  [19] S. Roth and M. J. Black. Fields of experts: A framework for learning image priors. In IEEE Conf. on Computer Vision and Pattern Recognition, 2005. 1, 2, 7, 8  where the last numbers (1, 2, 7, 8) are the pages where I cited the paper in MY TEXT?  This would be like a reversed reference, or a index for bibliography. $G$ is a finite group such that $|G|=n$. Let $p$ be the smallest prime such that $p|n$. If $H\triangleleft G$ such that $|H|=p$, then prove that $H\subset Z(G)$.  My Work:  Since $|H|$ is a prime $H\cong \mathbb{Z}/(p)$. Hence $H$ is cyclic and abelian. I was stuck afterwards. Can anyone please give me a hint? Is there a thumb-rule for designing neural-networks? I know that a neural-network architecture is mostly based on the problem itself and the types of input/output, but still - there's always a "square one" when starting to build one. So my question is - given a input dataset of MxN (M  is the number of records, N is the number of features) and a C possible output classes - is there a thumb-rule to how many layers/units should we start with? How can a "proper" function have a vertical slope? Plotting the function $f(x)=x^{1/3}$ defined for any real number $x$ gives us:   Since $f$ is a function, for any given $x$ value it maps to a single y value (and not more than one $y$ value, because that would mean it's not a function as it fails the vertical line test). This function also has a vertical tangent at $x=0$.   My question is: how can we have a function that also has a vertical tangent? To get a vertical tangent we need 2 vertical points, which means that we are not working with a "proper" function as it has multiple y values mapping to a single $x$. How is it possible for a "proper" function to have a vertical tangent?  As I understand, in the graph I pasted we cannot take the derivative of x=0 because the slope is vertical, hence we cannot see the instantaneous rate of change of x to y as the y value is not a value (or many values, which ever way you want to look at it). How is it possible to have a perfectly vertical slope on a function? In this case I can imagine a very steep curve at 0.... but vertical?!? I can't wrap my mind around it. How can we get a vertical slope on a non vertical function? Is there a built-in method to compare collections? I would like to compare the contents of a couple of collections in my Equals method.  I have a Dictionary and an IList.  Is there a built-in method to do this?  Edited: I want to compare two Dictionaries and two ILists, so I think what equality means is clear - if the two dictionaries contain the same keys mapped to the same values, then they're equal.

I am trying to make a through hole using inward extrusion. I enterd into edit mode, then I drawed an outline of my hole using knife tool. then I turn into wireframe shading, rotate my view an select snap to faces and then extrude the hole outline inward  so the hole is created successfully, but I still have a face at the hole bottom. I can select this face separately  But If I try to delete it, I siply delete this face (I can't select it anymore after deleteting), but I do not see through hole, so the basic cube face is still here. So how to remove the hole bottom? If $\sum_{n=1}^{\infty} a_n$ is absolutely convergent, then $\sum_{n=1}^{\infty} (a_n)^2$ is convergent Drawing Day and Night on a Google Map I'm looking to plot day/night on a Google map, for an arbitrary point in time. I'm familiar with generating map tiles; I'm just looking for an algorithm to tell me whether a particular point on the globe is currently in daylight or darkness, or to otherwise plot the curve of the day/night interface onto the map.  I've done some searching, but it's possible I don't even know enough about the problem domain here to know what terms to search for!  Any ideas?
