Is ubuntu supports on Lenovo g5070 and how to install...
I would like to see a full how-to guide on how to install Ubuntu.
Line breaks in listings Is there a way like wrap the line after at most 60 letters but it should not break inside some commands like listings does?  Example:      \documentclass[a5paper]{article}     \usepackage[T1]{fontenc}     \usepackage[utf8]{inputenc}     \usepackage{listings}     \usepackage{xcolor}      \lstset{%       language=[LaTeX]TeX,       backgroundcolor=\color{gray!25},       basicstyle=\ttfamily,       breaklines=true,       columns=fullflexible     }      \begin{document}     \begin{lstlisting}     The roadrunner is the fastest running bird \remark{Check this again with a zoologist!}.     \end{lstlisting}     \end{document}   Output:      The roadrunner is the fastest running bird         remark{Check this again with a zoologist!}.   That should not happen! In my eyes this problem is not discussed in . Why does my item name not show up in 1.13? I am in 1.13 Pre-Release 7 trying to make a one command creation and I need an item with a specific name. The command I use is /give @p diamond_sword{display:{Name:"Sword of Power"}} and it gives my a diamond sword, but it doesn't have the name.   This is me running the command.   This is the command not working. How to interpret the output of XGBoost importance? I ran a xgboost model. I don't exactly know how to interpret the output of xgb.importance.  What is the meaning of Gain, Cover, and Frequency and how do we interpret them?  Also, what does Split, RealCover, and RealCover% mean? I have some extra parameters   Are there any other parameters that can tell me more about feature importances?  From the R documentation, I have some understanding that Gain is something similar to Information gain and Frequency is number of times a feature is used across all the trees. I have no idea what Cover is.  I ran the example code given in the link (and also tried doing the same on the problem that I am working on), but the split definition given there did not match with the numbers that I calculated.  importance_matrix   Output:             Feature         Gain        Cover    Frequence   1:            xxx 2.276101e-01 0.0618490331 1.913283e-02   2:           xxxx 2.047495e-01 0.1337406946 1.373710e-01   3:           xxxx 1.239551e-01 0.1032614896 1.319798e-01   4:           xxxx 6.269780e-02 0.0431682707 1.098646e-01   5:          xxxxx 6.004842e-02 0.0305611830 1.709108e-02  214:     xxxxxxxxxx 4.599139e-06 0.0001551098 1.147052e-05 215:     xxxxxxxxxx 4.500927e-06 0.0001665320 1.147052e-05 216:   xxxxxxxxxxxx 3.899363e-06 0.0001536857 1.147052e-05 217: xxxxxxxxxxxxxx 3.619348e-06 0.0001808504 1.147052e-05 218:  xxxxxxxxxxxxx 3.429679e-06 0.0001792233 1.147052e-05 Get Last Friday of Month in Java How can I manage computers using my Firefox Sync account? I`m using Firefox Sync on a bunch of computers.   I would like to manage my account, by removing some computers. I can't find the place to do this, it should be on the Firefox Sync page, but the official page only has the privacy and download information. How to tenderize large squid? My whole life I've been buying small squid (maybe 4-6" long bodies without the head and tentacles), which are very mildly chewy and tender.  All it takes is sautee them in a little OO and they are good to eat, IOW, no additional tenderizing is needed.  Yesterday I got some large squid, about 1 lb each before cleaning, probably 10"+ long without the head, probably 5-6 times as much meat as the little ones I usually get.  I remember trying to cook that before and they came out very tough and with a bit of unpleasant odor.  Is there a way to marinate and tenderize large squid and to somehow neutralize the odor? Is there any app for Stack Exchange? Is there any app available in the Android Market for Stack Exchange sites? How secure is Activation Lock on iOS 7 (and later)? Which are the non Schengen countries that allow entry for Schengen visa holders? There are countries in the Balkan area that allow entry if you have a Schengen visa but am not able find a definite list of all those countries. Knowing that will save me getting a visa for all those countries when I do my mega Euro trip. I have a sample composed by 2500 count data values. I've plotted in R the corresponding histogram and ecdf. I've run the One-Sample Kolmogorov-Smirnov test to check if the distribution is either exponential or poisson, but I got negative results.  Is it possible that the One-Sample Kolmogorov-Smirnov test, it's not the correct test to work with this count data.  What is the best way to identify a distribution for this kind of data? Is the function differentiable at $0$? Let $$f(x) = \begin{cases}\begin{align*}&amp;\cos{\dfrac{1}{x}}, &amp;x \neq0 \\ &amp;0, &amp;x=0. \end{align*}\end{cases}$$ Is the function $F(x) = \displaystyle \int_{0}^x f dx$ differentiable at $0$?  We can see that the function $f(x)$ is continuous everywhere except $x=0$. In order to show differentiability we will need to show the derivatives from the left and right are equal. So we need to show that $$\lim_{h \to 0^+} \dfrac{F(x+h)-F(x)}{h} = \lim_{h \to 0^-} \dfrac{F(x+h)-F(x)}{h}.$$ The derivative from the right is $$\lim_{h \to 0^+} \dfrac{F(x+h)-F(x)}{h} = \lim_{h \to 0^+} \dfrac{\displaystyle \int_{0}^x\cos{\dfrac{1}{x+h}}-\int_{0}^x\cos{\dfrac{1}{x}}}{h}$$ and the derivative from the left is $$\lim_{h \to 0^-} \dfrac{F(x+h)-F(x)}{h} = \lim_{h \to 0^-} \dfrac{\displaystyle \int_{0}^x\cos{\dfrac{1}{x+h}}-\int_{0}^x\cos{\dfrac{1}{x}}}{h}.$$ I am not sure how to proceed. Using Through to evaluate complex expressions Character Limit in HTML How do you impose a character limit on a text input in HTML? Get current URL with jQuery? I am using jQuery. How do I get the path of the current URL and assign it to a variable?  Example URL:  http://localhost/menuname.de?foo=bar&amp;amp;number=0 If i entered "name" in my text box while it saved it must be saved like "Name"   Capital letters in the first letter of Alphabet  It must not show any error messages it must directly save Typically, to box in some text, I use the following:  \fbox {     \parbox{\linewidth}{     This is some text! Blah blah blah...     } }   However, say I have a verbatim block within that. It will never compile. Anyone know how I could draw a box around text which contains a verbatim block? I should note that I want to be able to draw a box around not just a verbatim block. For example, I would want to draw a box around something like:  This is text. \begin{verbatim} This is some more text. \end{verbatim} And this is even more text. Paucity of words for relationships Why is Tony Stark in the Iron Man suit unaffected by G-forces, inertia and blunt force trauma? Tony's suit is an engineering marvel, and they explain many facets of the technology to help give legitimacy to the special powers, abilities and weapons it has.  I never read the Iron Man comics, but in the movie they really don't have a technological explanation for how he miraculously seems to be unaffected by crushing G-forces of sudden acceleration, the inertia of sudden stops and hair-pin turns, and especially the blunt force trauma from getting smashed in the face with Thor's hammer.  Certainly it appears the suit takes punishment, but Tony always remains unscatched, never a collapsed lung, broken bone or even a bloody nose.  In my infantile understanding of theoretical physics, the same technology that would be used to counter G-forces and sudden blunt force trauma to the body inside would be the very same technology used for  which in my honest opinion would be a much more stunning technological achievement than his heralded Arc Reactor.  Was their ever an explanation proferred for this and if so was it indeed attributed to Anti-Gravity? "Reality" of EM waves vs. wavefunction of individual photons - why not treat the wave function as equally "Real"? In thinking how to ask this question (somewhat) succinctly, I keep coming back to a Microwave Oven.  A Microwave Oven has a grid of holes over the window specifically designed to be smaller in diameter than the wavelength of the microwaves it produces, yet larger than the wavelengths of the visible light spectrum - this is so you can watch your food being heated without getting an eye full of microwaves.  The "realness" of electromagnetic waves seems indisputable - both from the microwave example above, and also because if I want to broadcast a radio wave with a certain wavelength, then I need to make sure I have an antenna of corresponding length to produce the wave I'm looking for.  Furthermore, we discuss and treat these waves as real, measurable "objects" that exist and can be manipulated.     Now, if I want to describe the behavior of my Microwave Oven in the framework of QM (let's pretend my oven is going to only produce 1 photon of energy corresponding to a wavelength of the microwave spectrum for simplicity) then I'll describe the behavior of that photon as a wavefunction that evolves over time and gives a probability distribution within my microwave that similarly does not allow the photon to pass through the safety grid and exit the oven cavity giving me a retinal burn.  The difference is, the wavefunction is never treated as something "real" in this description.  When the safety grid is described as working to protect you because it has holes smaller than the wavelength of the classical waves it's blocking, this is a useful description that seems to describe "real" objects/be-ables.  While it is possible to describe why an individual photon has low probability of passing through the same grid but extended physical properties such as wavelength (in space) are treated as non-real because we're dealing with a point particle and with behavior described by something we also treat as non-real (the wavefunction); it seems unclear to me why we insist this wave function which predicts behavior of physical measurements so well is somehow "non-real."    Put another way, if we have no problem treating EM waves as "Real," then why do we insist on treating the wavefunction that describes the same behavior as "unreal?"  I understand there is recent research (Eric Cavalcanti and his group for one) trying to argue this point, but as every respectable physics professor, I've ever encountered, has treated the wavefunction as an indisputably non-real mathematical tool, I needed to ask this community for an answer. In R, what does qqnorm actually do? qqnorm(x) plot(qnorm(seq(80)/81),sort(x))   Finding that the plots produced by the commands above are slightly different from each other, I tried this:  qqnorm(qnorm(seq(80)/81))   I got a slightly less than perfect line.  I'd have tried regressing the result of qnorm(seq(80)/81) on the variable that was plotted on the $x$-axis and plotting residuals against the predictor, expecting to see some graceful curve, but for the fact that I don't know what to use as the predictor.  Possibly such a residual plot would reveal more than just the graceful S-shaped thing I'd anticipate.  So my question is this: if the thing on the $x$-axis in the plot produced by qqnorm is not what I get from qnorm(seq(80)/81) (and what I did shows that indeed it is not), then what is it?
