As the title said, I want to set my Firefox application to always open up in second monitor. I'm using Xubuntu 14.04 and default ubuntu driver for NVDIA (noveau I think).   In Windows there is DisplayFusion that can this. Does Ubuntu have same equivalent app/combination key that can do the same?
I have Ubuntu 14.04 and two monitors. When I open applications I need some of them to be on the primary monitor and others On the secondary. At the moment, apps always open in the primary monitor.   I have dash icons only on one (left) display, so I can't launch apps using the cursor or active window setting from Compiz.
How could a statement be true without proof? Generate mesh at run time Is it possible to generate mesh at runtime in blender game engine? That is, is it possible for blender to generate meshes using python code when the game runs?  I really would like to know if this is possible, as my final year project requires use of this. Proof of the equality $\sum\limits_{k=1}^{\infty} \frac{k^2}{2^k} = 6$ I'm arriving to the US by air, but departing via land. How do I end form I-94 now that it is only electronic? If $F\supset E$ and $E\supset k$ are normal extensions. I want a counter-example where $F\supset k$ is not normal Why must a field whose a group of units is cyclic be finite? Let $F$ be a field and $F^\times$ be its group of units. If $F^\times$ is cyclic, then show that $F$ is finite.  I'm a bit stuck. I know that I can represent $F^\times = \langle u \rangle$ for some $u \in F^\times$ and that we must have that $|F^\times| = o(u)$, where $o(u)$ denotes the order of $u$ in $F^\times$.  I tried assuming $o(u) = \infty$, but I'm not sure exactly where to go from there. I was wondering if I could get a hint. What's the difference between using a 50mm f/1.8G and a 50mm f/1.8D with a Nikon D80? Recently, Nikon announced their , as revamp of the old 50mm f/1.8D. :     The main difference between this new   "nifty fifty" and the almost   decade-old ƒ1.8D is that it has an   autofocus motor inside. This means you   can use it with any current or recent   Nikon SLR. The older lens lacks this   motor and is instead driven by one in   the camera, which cheaper bodies don't   have.   I currently use a Nikon D80 (and I don't plan on changing that any time soon), and I've been considering getting such a lens. Is there any difference between the D and the G lenses when used on a D80? I believe that the D one works just as well, since D80's have internal autofocus motors - is that right?  Besides the autofocus motor aspect, is there any other big difference between them? Since the D is priced at around $120 and the G at $220, should I just get the D? Say I have some historical data e.g., past stock prices, airline ticket price fluctuations, past financial data of the company...  Now someone (or some formula) comes along and says "let's take/use the log of the distribution" and here's where I go WHY?  Questions:   WHY should one take the log of the distribution in the first place? WHAT does the log of the distribution 'give/simplify' that the original distribution couldn't/didn't? Is the log transformation 'lossless'? I.e., when transforming to log-space and analyzing the data, do the same conclusions hold for the original distribution? How come? And lastly WHEN to take the log of the distribution? Under what conditions does one decide to do this?   I've really wanted to understand log-based distributions (for example lognormal) but I never understood the when/why aspects - i.e., the log of the distribution is a normal distribution, so what? What does that even tell and me and why bother? Hence the question!  UPDATE: As per @whuber's comment I looked at the posts and for some reason I do understand the use of log transforms and their application in linear regression, since you can draw a relation between the independent variable and the log of the dependent variable. However, my question is generic in the sense of analyzing the distribution itself - there is no relation per se that I can conclude to help understand the reason of taking logs to analyze a distribution. I hope I'm making sense :-/  In regression analysis you do have constraints on the type/fit/distribution of the data and you can transform it and define a relation between the independent and (not transformed) dependent variable. But when/why would one do that for a distribution in isolation where constraints of type/fit/distribution are not necessarily applicable in a framework (like regression). I hope the clarification makes things more clear than confusing :)  This question deserves a clear answer as to "WHY and WHEN" Uncheck checkboxes by changing particular checkbox state I have custom fields in contacts form named checkbox1__c, checkbox11__c, checkbox12__c, checkbox13__c.  When I check checkbox1__c then I want checkbox11__c,  checkbox12__c,  checkbox13__c to be unchecked.  When I unchecked checkbox1__c then I want checkbox11__c, checkbox12__c, checkbox13__c to be checked.  Is there any way to do this by using validation-rules? If not no way to this by validation-rules, then what is the best way to do this? What is the proof that the total number of subsets of a set is $2^n$? Vector bundle on a quadric $Q$ How can we prove that any bijection on any set is  a composition of 2 involutions ?  Since involutions are bijections mapping elements of a set to elements of the same set, I find it weird that this applies to any bijection.  Thanks for your help ! How do I prevent yum from updating a particular RPM? For certain reasons I have to keep a slightly older version of a particular RPM installed on my box (Fedora 11). The problem is that every time I do a package update yum (or one of its GUI equivalents) wants to update this RPM to the latest version, which is annoying - especially when I update it by mistake.  Is there a way to 'pin' this version so that yum knows to never try and update it? GTA V Online Character Transfer PS3 to PS4 I recently just bought a PS4 that I couldn't pass up (Price Wise) and decided to try and transfer my GTA V Online Character.  Stats: All stat bars full $204,000,000 Rank: 149  I've been playing the game since it came out, which was around 2013 I believe. I quit playing the game about 8 months ago because my hard drive in my PS3 died on me so I decided to put the console on the shelf for a while. Like stated above, I just bought me a new PS4 and was looking to try and transfer my character over. I tried calling Rockstar Support about my situation and all they told me was that they don't allow transfers anymore.   So here's my question... Is there absolutely any way that I can transfer my character to my next gen console? Changing color and fonts of itemize I have keypair (u,r), and two pieces of data, X and Y.  I reveal X publicly but keep Y secret. Y has high entropy.  I then concatenate X and Y, into Z.  I encrypt Z, into "encrypt(Z,u) = Q". r is needed to decrypt Q back into Z.  Later, (when it doesn't matter), r will be revealed and everyone will decrypt Q into Z. At that point, everyone will know that, all along, Q "contained" X. Can I prove that Q contains X before r is revealed (including interactive zero-knowledge proofs)? I've been trying to understand how the second order derivative "formula" works:  $$\lim_{h\to0} \frac{f(x+h) - 2f(x) + f(x-h)}{h^2}$$  So, the rate of change of the rate of change for an arbitrary continuous function. It basically feels right, since it samples "the after $x+h$ and the before $x-h$" and the $h^2$ is there (due to the expected /h/h -> /h*h), but I'm having trouble finding the equation on my own.  It's is basically a derivative of a derivative, right? Newtonian notation declares as $f''$ and Leibniz's as $\frac{\partial^2{y}}{\partial{x}^2}$ which dissolves into:  $$(f')'$$ and $$\frac{\partial{}}{\partial{x}}\frac{\partial{f}}{\partial{x}}$$  So, first derivation shows the rate of change of a function's value relative to input. The second derivative shows the rate of change of the actual rate of change, suggesting information relating to how frequenly it changes.  The original one is rather straightforward:  $$\frac{\Delta y}{\Delta x} = \lim_{h\to0} \frac{f(x+h) - f(x)}{x + h - x} = \lim_{h\to0} \frac{f(x+h) - f(x)}{h}$$  And can easily be shown that $f'(x) = nx^{n-1} + \dots$ is correct for the more forthcoming of polynomial functions. So, my logic suggests that to get the derivative of a derivative, one only needs to send the derivative function as input to finding the new derivative. I'll drop the $\lim_{h\to0}$ for simplicity:  $$f'(x) = \frac{f(x+h) - f(x)}{h}$$  So, the derivative of the derivative should be:  $$f''(x) = \lim_{h\to0} \frac{f'(x+h) - f'(x)}{h}$$  $$f''(x) = \lim_{h\to0} \frac{  \frac{ f(x+2h) - f(x+h)}{h} - \frac{ f(x+h) - f(x)}{h}  }{h}$$  $$f''(x) = \lim_{h\to0} \frac{  \frac{ f(x+2h) - f(x+h) - f(x+h) + f(x)}{h}  }{h}$$  $$f''(x) = \lim_{h\to0} \frac{  f(x+2h) - f(x+h) - f(x+h) + f(x)  }{h^2}$$  $$f''(x) = \lim_{h\to0} \frac{  f(x+2h) - 2f(x+h) + f(x)  }{h^2}$$  What am I doing wrong? Perhaps it is the mess of it all, but I just can't see it. Please help. How can I calculate the R-squared of a regression with arima errors using R? If I have an arima object like a:  set.seed(100) x1 &lt;- cumsum(runif(100)) x2 &lt;- c(rnorm(25, 20), rep(0, 75)) x3 &lt;- x1 + x2  dummy = c(rep(1, 25), rep(0, 75))  a &lt;- arima(x3, order=c(0, 1, 0), xreg=dummy) print(a)   .  Series: x3  ARIMA(0,1,0)                      Call: arima(x = x3, order = c(0, 1, 0), xreg = dummy)   Coefficients:         dummy       17.7665 s.e.   1.1434  sigma^2 estimated as 1.307:  log likelihood = -153.74 AIC = 311.48   AICc = 311.6   BIC = 316.67   How do calculate the R squared of this regression? I was going through some articles about "African American Vernacular English". . . These articles give some examples, but they do not clearly specify hard rules to be followed in AAVE.  First of all, I don't even have strong skills in Standard English, so understanding AAVE seems a lot more difficult for me. I did, however, craft a few sentences in both SE and AAVE to validate what understanding I do have. Are the following conversions correct? You don't have to validate each and every item, but rather guide me with rules that I should follow, but didn't, in the following examples.   What the hell are you all doing here?  —  What the hell y'all doin' here? Hey you! What the hell are you doing man? Stop that nonsense now. Do you get it?  — Hey you! What the hell ya doin’ man? Stop that nonsense now. D'ya get it? Come on, can't you open your mouths?   — Come on, ya can't open your mouths??  Hey, who's out there?  —  Hey, who out there? I know, you're listening to us   — I know, ya listenin’ to us Somebody is out there man. — Somebody out there man. Wow, it's delicious.  — Wow, it delicious. Holy crap, who're these people? — Holy crap, who these people? Can I use my familiar to cast Warding Bond on myself? Find Familiar lets you cast touch spells through your familiar. Warding Bond is a Touch spell, that creates a connection between "you and the target". I can't find anything against it, but would it be possible to have my Wizard make his familiar cast Warding Bond on the Wizard himself, so that the Wizard gets the +1 to AC and saving throws and resistance to damage?  I realized after I wrote this much that Wizards don't get Warding Bond, but I think the question is still valid for multiclassers.
