Partitioning sum of squares In Age of Ultron, Thor seems to know something he possibly shouldn't? Sorry for the cryptic title, but I realise the film has only just been released in the UK and Europe and is yet to be released in the US.  I'll hide all substantial parts of my question, just in case. I don't want to spoil anything.     At the end of Age of Ultron, Thor states that 4 infinity stones have now shown up in the last few years.   So,     By my count we have the Tesseract, from several of the first few films. The Aether, from Thor 2. The Chitauri Scepter, again from several films. And finally, we have The Orb, from Guardians.    Now, to my knowledge     Thor, and indeed none of the Avengers, should know about The Orb. I don't remember Thor visiting the Collector between GoTG and the AoU. So, how did Thor know that The Orb had appeared? Or is he referencing a different infinity stone?   I'm looking for an in universe answer, ideally. save as a video as .mp4 So I made an intro using animation and it saves it as a .blend and I want it so save as a video like .mp4 or something like that. I've tried changing the codec because I tried opening the intro with windows media instead of blend. I didn't try all the codec's but I tried some of them. tmux: shared session, one user in a pane, another in another pane, two different cursors I've decided to try tmux: have been reading the docs and googling around, trying to find a way to have two users sharing a session, each with a different cursor.  However, giving 777 permissions to the socket, or creating a group, chgrping the socket and adding both users to it, seems to let that same socket be used to share a session with only one cursor: both users can write, but always in the same cursor position.  Right now both users are in the same home server over ssh, and the idea is to be able to have:   A terminal in a, let's say, left pane, where I can type commands Another terminal in a right pane, where I can see another user typing commands  in his own terminal The same thing for the other user   What I'm doing at the moment is using two sessions (not shared) and a script -f and tail -f combination that kinda works for reading each other's key strokes, but I reckon there is probably some way of doing this using tmux sharing capabilities.  Is there a way to get this idea working with write support in each other's terminal?  What is the better way to do this? Non-trivial cyclic group with unique generator Let $G$ be a non-trivial cyclic group with an unique generator. Show that $G$ has exactly two elements.   Let $g$ be a generator of $G$. My first idea to approach the problem was to show that if $|G|=n &gt; 2$ then there is an integer $k$ between 1 and $n$ such that $\langle g^k \rangle = G$ or, equivalently, $g \in \langle g^k \rangle$. My second idea was to analyse the problem in 2 separate cases. For the first one, if $n$ is prime, let $k$ be a positive integer then, by Lagrange's Theorem, $|g^k| \mid n$ and, therefore, $\langle g^k \rangle = n$. Hence, we must conclude that, if $n &gt; 2$ the generator cannot be unique. For the second case, where $n$ is composite, I was hoping to get to a contradiction, but could not advance any further. Is there a way to develop either of these ideas or is it necessary a new approach? Tentative definitions in C and linking Clipboard.GetText returns null (empty string) My clipboard is populated with text, but when I run  string clipboardData = Clipboard.GetText(System.Windows.Forms.TextDataFormat.Text);   I get back an empty string. I've toyed with various forms of the call including:  string clipboardData = Clipboard.GetText(); string clipboardData = Clipboard.GetText(System.Windows.Forms.TextDataFormat.UnicodeText);   But with the same result.  Am I missing something obvious? Deciding whether $2^{\sqrt2}$ is irrational/transcendental Is $2^\sqrt{2}$ irrational? Is it transcendental? Redirect stdout over ssh I would like to run  something &gt; file   on a remote system through ssh, but if I run  ssh host something &gt; file   the redirection is executed locally as ssh etc &gt; file  I've tried it with ' or '' or dd or with a pipe | instead, but I can't get it to work. How can this be done? I have a Canon Powershot A710 and I previously had a previous Powershot A-series model. I love them due to the high amount of control they offer. Sadly, they both suck in low light conditions, their flash is very unresponsive, and the camera takes several seconds preparing itself for the next shot after a flash shot. And even then, the pictures they take in low light/flash are as bad as good are those with good light.  I'd like a camera which gives a lot of control options, but what do I need to look for to find one that's great in low light, with or without flash? Why was the MCU Super Soldier program considered a failure? In Marvel Cinematic Universe, military tried to create super soldiers like Hulk, but they failed. So, the program was shut down.  Where did they fail? Didn't Blonsky get Wolverine-type super healing capability? Why couldn't it make the military stronger? Other than this, wasn't Abomination a success (despite the fact that it wasn't an original work of the military)? He was defeated by Hulk, but enemy forces don't have a Hulk. When it comes to anger, who cares as long as you are focused on the target? Abomination was indeed in full control and he was always after Hulk. How to run .sh script with keybind Question: For every polynomial $P(x)$ of degree at n we have $$\sum_{i=0}^{n+1}(-1)^i\binom{n+1}{i}P(i)=0$$  Well I was inducting on degree of the polynomial, for $n=0$ its true and I got a bit confused in the inductive step, actually I cant figure the inductive step.   Is this property (if true) a famous one?  Thank you for your help. Share a Folder between two Local Users I and my brother have User Accounts on this machine. I want to share the Documents directory with him.  Is there a STRAIGHTFORWARD way to do it?  I am not a power user so I am looking for a way to do this using nautilus, rather than a script or a way that requires creating symlinks.  I can download an application if i have to.  Last time I wanted to do this I just copied the contents to /home for both of us to use.  Something I can do in System Settings would be appreciated "Always on Top" Windows with Java In Java, is there a way to have a window that is "Always on top" regardless if the user switches focus to another application?  I've searched the web, and all of the solutions lean to some sort of JNI interface with native bindings.  Truly this can't be the only way to do it?.. or is it? Does every number not ending with zero have a multiple without zero digits at all?   We consider numbers in their usual base 10 representation. we don't consider numbers ending with $0$, because all multiples of such numbers end with $0$.   It can be proven that all powers of $2$ have such a multiple: Indeed, for every number of the form $2^n$, we can find a multiple $l$ of it whose last $n$ digits are nonzero (This can be done by repeatedly multiplying a number by $10^k+1$, as explained ), and then forget all other digits; these last $n$ digits constitute a number that is still divisible by $2^n$, since it is obtained from $l$ by subtracting a multiple of $10^n$ which is in particular a multiple of $2^n$.  The same argument shows that every power of $5$ has a multiple without zeros, but this does not seem to generalize to other numbers.  My intuition is actually that the claim is not true, since the density of numbers without any zero digits approaches $0$ for big numbers. This is because the probability of a random number with at most $n$ digits to contain only nonzero digits is $(\frac{9}{10})^n$. Thus big numbers "nearly always" contain a zero. This hints on the existence of a counterexample, but does not prove its existence. I am trying to install  under Wine. The program setup continually requests proxy settings. My broker tells me this shouldn't happen, and is a problem on my end. Here is what I have tried to attempt to solve this error:   I have gone into Network settings and proxy is set to none. I have looked in Wine Regedit and proxy_enable is set to 0. I have checked the firewall settings on my modem. I have tried reinstalling wine. I have installed lib32nss-mdns I can log on to my modem in iexplore using the gateway ip but thats it I've set my DNS to 10.0.0.138 to reflect the gateway I've set up a 32 bit Wine prefix   How should I proceed in solving this? How do I install Java? How do I install Java, including in my browser, so websites with Java work? Our team is developing a new system and it has a Warehouse table that must have a hierarchical relationship between entries since a customer can have 1st, 2nd, 3rd and Nth degree warehouses.  We first thought that  was the best way to do it. By creating a Parent and a Child column on the table and then making Parent the FK to Child (on the same table) but friend DBA told us that there is a different way.  So, for instance, we had thought about making a table like this:  CREATE TABLE Warehouse( filterId INT PRIMARY KEY IDENTITY, parentId INT NOT NULL, active BOOL DEFAULT 1, warehouseName VARCHAR(30) NOT NULL, FOREIGN KEY parentId REFERENCES Warehouse(filterId)  | FILTERID   | PARENTID | ACTIVE | WAREHOUSENAME | -------------------------------------------------- |          1 |        0 |      1 | N WAREHOUSE 1 | |          2 |        1 |      1 | ROOM 1        | |          3 |        1 |      1 | ROOM 2        | |          4 |        1 |      1 | ROOM 3        | |          5 |        1 |      1 | ROOM 4        | |          6 |        2 |      1 | SHELF 1       | |          7 |        2 |      1 | SHELF 2       | |          8 |        2 |      1 | SHELF 3       | |          9 |        2 |      1 | SHELF 4       | |         10 |        2 |      1 | SHELF 5       | |         11 |        2 |      1 | SHELF 6       | |         12 |        2 |      0 | SHELF 7       | |         13 |        3 |      1 | BOX 1         | |         14 |        3 |      0 | BOX 2         | |         15 |        3 |      1 | BOX 3         | |         16 |        3 |      1 | BOX 4         | --------------------------------------------------   But this DBA said that we should work on something like this:  CREATE TABLE Warehouse( filterId VARCHAR(20) PRIMARY KEY, active BOOLEAN DEFAULT 1, warehouseName VARCHAR(30) NOT NULL)   | FILTERID   | ACTIVE | WAREHOUSENAME | --------------------------------------- | 1.00       |      1 | N WAREHOUSE 1 | | 1.01       |      1 | ROOM 1        | | 1.02       |      1 | ROOM 2        | | 1.03       |      1 | ROOM 3        | | 1.04       |      1 | ROOM 4        | | 1.01.01    |      1 | SHELF 1       | | 1.01.02    |      1 | SHELF 2       | | 1.01.03    |      1 | SHELF 3       | | 1.01.04    |      1 | SHELF 4       | | 1.01.05    |      1 | SHELF 5       | | 1.01.06    |      1 | SHELF 6       | | 1.01.07    |      0 | SHELF 7       | | 1.01.01.01 |      1 | BOX 1         | | 1.01.01.02 |      0 | BOX 2         | | 1.01.01.03 |      1 | BOX 3         | | 1.01.01.04 |      1 | BOX 4         | ---------------------------------------   Which way should we follow?   On one hand we have a relationship between parentId and filterId; on the other we do not have any relationship, but it is easy to understand where does the entry belong.  Not all the warehouses are of the same level - that's what I mean by degree. They should be ordered like: For Customer A, 1 is parent of 1.1 and 1.2, 2 is parent of 2.1, 3 is parent of 3.1 and 4 is parent of 4.1 and 4.2 - but 1, 2, 3 and 4 are of the same level (1st level), and 1.1, 1.2, 2.1, 3.1, 4.1 and 4.2 are also of the same level (2nd level) but not of the same parents. For which values $r, s \in \mathbb R$ is the set $\{u, v, w\}$ linearly independent?
