How can I pin a program to the Windows 7 Taskbar, with parameters? Interpretation of ROC curve I have a ROC curve like the figure below:   What can be inferred given this kind of curve in general?  What are the differences of states 1, 2 and 3 in the figure?  What causes the diagram to jump straight from state 1 to state 3? Most of the ROC curves on the internet look like the figure below: Shutdown and User button missing in panel I faced with a problem after update,   I missed 2 buttons from above panel, System menu (including shutdown, suspend &amp; …) and User (including log out &amp; …)  how can I restore them !?... Word for "things which exist" The sum is $$\sum_{n=1}^{\infty} \frac{n+2^n}{n+3^n}$$ Is this convergent or divergent? I tried to use the divergent test but the test fail because $a_n = (n+2^n)/(n+3^n) = 0 $ as $n$ goes to infinity. Could someone point me to the right direction?  Thanks As the question title suggests, how do I see that every left ideal of a square matrix ring over a field is principal? The question is to calculate the radius of convergence of $\sum\limits_{n=0}^\infty n!x^{n^2}$.  I dont know how to calculate R.O.C for such type of questions involving $n^2$ as power of x. How do we do this? Any help appreciated. Why is learning modern algebraic geometry so complicated? Google search results showing up a URL on its search which doesn't exist on the website I am using a keyword to display a website page on google search. After entering the keyword, on the first page of google, I am redirected to a page, whose domain is exactly similar to the website whose page I want to display, but it is showing a page which doesn't even exist on the domain. Also, as similar domain with spam characteristics is also getting displayed.   To practically demonstrate this issue, do follow the below steps.   Go to  Type dolce streichquartett and click on search. The 4th/5th URL has this link http://www.dolce-streichquartett.de/?high_ry=/casinos/de/spielautomaten-casino-bregenz.php, which is no where on the website and looks like spam The 7th/8th link you see is http://deonlinecasino.org/doc/kostenlos-roulette-spielen-spielgeld-ausdrucken.php, which is exactly similar to the above with the title as the keyword but a different domain.   What is this issue and why is this happening? After a company has issued shares, why should it care if the value of the shares fluctuate? Since the shares are now publicly traded, if the value fluctuates, that is strictly a transaction between buyer and seller, none of whom are directly related to the company. E.g. if I sell X an iPhone for $100, why should I care if X is selling the iPhone to Y for 1 dollar or 1000 dollars? I have got my $100, so I need not bother. No? The equals() method in Java works unexpectedly on Long data type Should I use OLS of fixed effects for this model for estimating level of immigrants? I'm trying to estimate this model on immigration levels I found in a paper and I'm not sure if they used OLS or fixed effects, it says that its a simple OLS but then mentions adding the country fixed effects. can someone help? Gray cone obscuring/clipping the 3D Viewport Add Area 51 Meta to the app Playing Minecraft on Windows 10, owning a Xbox One disc I own a Minecraft disc for an Xbox One, and would like to play on my PC (ultimately, playing with others who will be on the Xbox).  I'm not too familiar with the Xbox account ecosystem, and with dozen different Minecraft editions, I'm lost as to how I can do that. Is an automorphism of the field of real numbers the identity map?

No synaptics driver loaded?   So, it seems the touchpad is not recognized as a synaptics touchpad. It works, but not the synaptics specific parts.  It's in mouse emulation mode (no idea what it means). And it works together with other pointing devices, especially the touchscreen (I can confirm this works).  I have tried adding i8042.nomux=1 to the kernel parameters, but it didn't change anything... Any hint ? Prove 24 divides $u^3-u$ for all odd natural numbers $u$ At our college, a professor told us to prove by a semi-formal demonstration (without complete induction):   For every odd natural: $24\mid(u^3-u)$   He said that that example was taken from a high school book - maybe I din't get something, but I really have no idea to prove that without using complete induction.  Any idea of smart demonstration?  Thanks for your help. (Excuse my bad English.) Why does Ubuntu only support versions for a limited time (and what does it mean)? How do I install Java?
