I have a complex embedded Linux software running on a gentoo derivative, on which a certain piece of code gets executed regularly every ~84 minutes. Sweeping through the main code to find places where this code might get executed was unsuccessful, and crontab also seems no possible explanation.   My question: Is it possible, by modifying the code in question, to find out which other process/code/file/service started it in the first place? Are there some information in the /proc directory I can use? Or is it impossible to find out the process that executed the given code?
I am flying to Tokyo in November, and I have the choice to go direct (paying extra) or transit via Seoul. Is 6 hours transit time enough to leave Incheon airport for a bit to see something of Seoul? It might make my trip more worthwhile to see something of South Korea too. I don't know much about the busyness of the airport around this time, and travel time between the airport and the city, so that's why I am asking. What causes close votes to be annotated with "(deleted)"? Fixing the sucktastic merge UI (for tags) How to compare two Pearson correlation coefficients Since a few days I do not get ahead when trying to compare two Pearson correlation coefficients. Imagine that I've got two datasets where on each I do a correlation between Land Surface Temperature and an urban metric. The datasets are different in their length, so the first one has round about 160.000 observables and the second one has about 2400 observables. For the correlation on the first dataset I get a Pearson of -0.74 and for the second I get -0.885. Now I want to find out whether these coefficients are significantly different from each other. Is there any appropriate method you could suggest?  I already played around with the Fisher-Z-Transformation, but from my point of view with no purposeful results. When I calculate the Fisher-Z on my coefficients, it results in 20.95 (Fisher-Z).  I would be very happy about suitable advices. What is the difference between a neural network and a deep neural network, and why do the deep ones work better? I haven't seen the question stated precisely in these terms, and this is why I make a new question.  What I am interested in knowing is not the definition of a neural network, but understanding the actual difference with a deep neural network.  For more context: I know what a neural network is and how backpropagation works. I know that a DNN must have multiple hidden layers. However, 10 years ago in class I learned that having several layers or one layer (not counting the input and output layers) was equivalent in terms of the functions a neural network is able to represent (see Cybenko's ), and that having more layers made it more complex to analyse without gain in performance. Obviously, that is not the case anymore.  I suppose, maybe wrongly, that the differences are in terms of training algorithm and properties rather than structure, and therefore I would really appreciate if the answer could underline the reasons that made the move to DNN possible (e.g. mathematical proof or randomly playing with networks?) and desirable (e.g. speed of convergence?) Why did Aragorn and Theoden ride out at the Hornburg? In the Battle of the Hornburg from The Two Towers, Aragorn and Theoden say "We must ride out." Why did they do this?  Was it just a matter of honor? Did they ride out on their horses in the middle of battle because they thought it was the end, as they were outnumbered? Was it because Aragorn knew Gandalf was coming so they were confident they were about to win? Let $\alpha,\beta,\gamma$ be the roots of $x^3-3x^2+1 = 0$. Prove that $$\alpha^n+\beta^n+\gamma^n \equiv 4^n+5^n+(-6)^n \pmod{17}$$ where $n$ is an integer.   It sort of makes sense why they are congruent since we can say $x^3-3x^2+1 \equiv (x-4)(x-5)(x+6) \pmod{17}$, but since $\alpha,\beta,\gamma$ aren't integers, how do we prove this? How can we communicate short messages long-distance? In our 5e game, we stole a boat. And a horse carriage. And a lot of other stuff for moving things between cities.   Our DM meant for this to be a way to skip road encounters. We decided to fund a shipping company and hire managers (Knights retainers, etc.) to turn a profit. The DM ruled that these would cover lifestyle expenses, provide us with easy smuggling, etc.   However, we want to keep tabs on the treasure we're moving back and forth.   What can we use for communicating with our managers from anywhere in the world? What about from say, across the city?  We don't need to communicate often or for long - a single round will work. All we need is for the manager to say "we need you back" How do I simulate in Photoshop what a piece will look like when printed on non-white paper? I'm designing a box in Photoshop that will be offset printed on unbleached paper. I haven't picked out a printer yet, so I don't know the exact kind of paper I'll be using and don't have access to it for proofs. For now I'm using a lightly-textured layer of tan color as a placeholder to mock it up.  What I'm trying to figure out is, how do I figure out how my design will look printed on natural paper rather than bleached white paper? I know that the brightness will be diminished and the hue will be altered, but I need to know how much so I can compensate for it as much as possible.  Is there a way to get at least a rough but reliably-simulated idea of how my prints will come out? Does it have to do with blend modes, or color separations? I'm at a bit of a loss here. Why does this cloth go down past the top surface of the cube? I was following a , and the presenter said that he did not change the default options other than enabling self-collision and increasing the collision object's friction from 5 to 10. His looks like the first image below, but when I tried that, the cloth goes down past the top surface and stops at the bottom surface (second and third images below). Why is it so?   I had a previous problem with cloth, and it was due to the objects' small size. This time, I made sure that both the cloth and the cube are large enough. (Cloth=7.68*8.22*1.99m, cube = 7.68*7.68*0.897m)  The project file can be . I want to create a scratch-card-like effect in new Unity UI's new Image tag.  I know it's possible with setPixels, but that's prohibitively expensive on mobile devices.  Something like this:    I'd like the user to be able to drag on any part of the image to "scratch off" the top layer and reveal the content underneath it.  How can I do this? How do I choose a macro lens for a Canon APS-C camera? Since reading the answers to my question about  I've been good about giving my meat time to defrost in the refrigerator. However, my plans for tonight have changed and I'd like to defrost some ground beef that is completely frozen for dinner this evening. What are my options to do so quickly and safely? I am trying to solve the following exercise:     Prove that complex multiplication does not extend to a multiplication   on $\mathbb R^3$ so as to make $\mathbb R^3$ into a real division   algebra.   I am aware of Frobenius' theorem that there are only three finite dimensional real associative division algebras. But the exercise would be pointless if the theorem was assumed.   Let $x,y \in \mathbb R^3$. Since $x y$ has to extend the complex multiplication:  $$xy = (x_1y_1-x_2y_2, x_1y_2 + x_2 y_1, ?)$$  I have no idea how I can proceed from here. Could someone tell me how to do this? It should be easy as the other exercises I did so far were also easy. Connecting two Ethernet PHY without magnetics? Uninstall Kali Linux from triple boot Find the limit of $\frac{\log(n+1)}{\log(n)}$ where $n\rightarrow\infty$. Here $n$ is a natural number so I guess we can't use L'Hopital Why does Skynet take prisoners? In the Terminator franchise, extermination camps are often mentioned. But from a machine-logic POV, wouldn't it make more sense to just kill all humans on sight, period? Or herd them into small areas and nuke them? (even today's military electronics are hardened against EMPs and Skynet wouldn't care about the environment.)   IIRC, the reasoning behind ghettoization / concentration camps / extermination camps / gas "showers" is to misdirect or mislead people both inside and outside the country as to what was really going on. But Skynet doesn't have to worry about bad publicity, and can manufacture all the free labor it needs. Is there any in-universe explanation for keeping large groups prisoners? I'm trying to amass a list of physics books with open-source licenses, like Creative Commons, GPL, etc. The books can be about a particular field in physics or about physics  in general.  What are some freely available great physics books on the Internet? edit: I'm aware that there are tons of freely available lecture notes online. Still, it'd be nice to be able to know the best available free resources around.  As a starter:         Table of contents sorted by field (in alphabetical order): Preventing LibreOffice from using smart quotes (“ ”) instead of (dumb) straight quotes? I use LibreOffice Calc to make lists of programs with different parameters to run on an hpc cluster. For each batch of commands I must do a find and replace on the smart quotes, as they cause errors in command line arguments. It would be nice to cut this step out of my work flow. Does anyone know how I might change the default punctuation used?  Edit: Apparently the title font transforms dumb quotes into smart quotes.  Smart quotes have a different symbol depending on if they are at the start or end (“ ”)  Dumb quotes use the same symbol for the start and the stop ( " )
