What are the salary and perks of Captain America? Brooklyn is Captain America's home, but times have changed since he was kid 8-9 decades ago. He can't afford a house there, now. This thing really troubled me when he said it in Avengers: Age of Ultron. I mean, I really became sympathetic, despite it being intended for fun.  What's the salary Captain America collects from (fallen) S.H.I.E.L.D. and/or Tony's Avengers organization? Can't they gift him a house in Brooklyn? I mean, he is one of Earth's mightiest heroes who help saved the world lots of times. Ubuntu 13.10 to 14.04 Lts does not upgrade, keeps showing error The update from Ubuntu 13.10 to 14.04 LTS does not work it keeps showing me an error as could not calculate the upgrade, even when I want it to get updated from the terminal it says the same error. I did not use the beta its the final Ubuntu 14.04 LTS.I have restarted my laptop for like 5-10 times no change. Disabling the software sources also does not help. Good books on "advanced" probabilities Variance of a bounded random variable Suppose that a random variable has a lower and an upper bound [0,1]. How to compute the variance of such a variable? Let $ G $ be an abelian group of order 6.  Then $ G $ has one element of order 6.  And so, $ G $ is cyclic and isomorphic to $ \mathbb Z _6 $.  In general, It is not true that an abelian group of order $n$ has an element of order $n$.  However in the case of $n=6$, it is true. I'm wondering there is any rule of the case (for example, a rule of $n$ that makes an abelian group cyclic). Host name changed remotely by wifi? Am am currently visiting TU Wien and today I connected my Debian Linux laptop to their eduroam wlan using wpa_supplicant and the credentials of my home institute - as always when I am visiting another scientific institution.  When I opened a terminal I noticed that my command promt was showing a different host name, and in fact, excecuting hostname gave me e244-082.eduroam.tuwien.ac.at instead of the usual host name of my machine x301.  I am very puzzled by this. How on earth can it be possible that connecting to a wlan changes my host name without my consent? Let's say you tell me to produce randomly a number from 1-100, and I choose the number 47. Can it be said that there is a specific reason I chose the number 47, and that it is not completely random? By random I mean that there is absolutely no reason this number in particular was chosen.    It seems odd to me, since it seems like since I have applied conscious effort to produce or choose a number within that range, or even without range, that it can't be truly random, but there might be a reason why I chose that number amongst the many others I could have chosen.  I guess the general question, which I'm interested to know if any philosophers in the past have discussed, is whether our thoughts are necessarily based on prior thoughts, or if thoughts can be truly spontaneous and random? Fréchet differentiability from Gâteaux differentiability Let $X$ be a Banach space and $\Omega \subset X$ be open.  The functional $f$ has a Gâteaux derivative $g \in X'$ at $u \in \Omega$ if, $\forall h\in X,$ $$\lim_{t \rightarrow 0}[f(u+th)-f(u)- \langle g,th \rangle]=0$$   How can I prove the following:  If $f$ has a continuous Gâteaux derivative on $\Omega$, then $f \in C^1(\Omega,\mathbb R)$. The binomial sum   $$s_n=\binom{n+1}{0}+\binom{n}{1}+\binom{n-1}{2}+\cdots$$   satisfies the Fibonacci relation.   I failed to prove that $\binom{n-k+1}{k}=\binom{n-k}{k}+\binom{n-k-1}{k}$... Any hints or suggestions? Is there a rule in British English about how to pronounce "either"? How to fix Eclipse with OpenJDK 9 Why is it so difficult to pull an immersed mug out of the water? Suppose I put a mug in the water and then tilt it so that the water gets inside. It then floats due to buoyant force. But if I try to pull it out then a lot of force is needed. That's due to suction? What exactly happens at the moment when the force I apply is enough to pull the mug out? And what causes the loud pop sound when that happens? "Oriented" vs. "orientated" How do I prove that 15462227 and 15462229 relatively prime? Getting my File Manager to link to my Google Drive I have a very small amount of storage on my computer and would like to conserve it, so I would like to know if there is a way to mount my Google Drive in Thunar or Nautilus on Ubuntu 12.04.5 LTS.   Yes, I know, it's weird that I'm saying that I have a small amount of storage when I have 2 file managers installed, but I literally have 5GB out of 16GB left. Changing default \citet font in biblatex I'm using biblatex to manage my citation in a natbib style :  \usepackage[style=alphabetic,maxnames=6,natbib=true]{biblatex}   However when I use the \citet command, the author's name is in a \textsc font, I would like to change this behavior so that the font used is the default one, but I could not find how to do this in biblatex's documentation. How to disable Ctrl+Shift+U? Ctrl+Shift+U is a combined shortcut in Eclipse. But when I press it, it shows up a u, just like input with an underline. I guess this shortcut has been declared by Ubuntu, so I can't use it. I used to solve this problem by typing Caps Lock first. Is there any better method? Image uploader shouldn't remove unused link references I've noticed this issue on a handful of other communities, but making the browser window narrow (mine is 1080x960) makes the .post-layout and #sidebar elements overlap. Maybe something to do with the grid CSS? The #mainbar element seems to be the correct width and changing the .post-layout's overflow-x to auto seems to "fix" it  From retrocomputing:    From this post, because we are meta after all:    Specs:   Google Chrome Version 78.0.3904.108 (Official Build) (64-bit) Ubuntu 18.04.3 LTS A screen of mine burnt out, and was replaced with a screen of lower resolution. It works in safe mode as that is in 800x600 resolution, but when I try to boot to normal mode, it fails. Is there a way to change the resolution for normal mode in safe mode?
