"May I have a glass of water" vs. "Can I have a glass of water": which is better, "may I" or "can I", when asking for something? What is the correct sentence when asking for something like while flying asking for a glass of water :     May I have a glass of water     or      Can I have a glass of water CSS bug with printing site pages (now with 100% more suggested fix included!) Why does an argument similiar to 0.999...=1 show 999...=-1? Will higher temperatures damage a computer over time, even when not reaching max? Quotient ring of Gaussian integers A very basic ring theory question, which I am not able to solve. How does one show that    $\mathbb{Z}[i]/(3-i) \cong \mathbb{Z}/10\mathbb{Z}$. Extending the result: $\mathbb{Z}[i]/(a-ib) \cong \mathbb{Z}/(a^{2}+b^{2})\mathbb{Z}$, if $a,b$ are relatively prime.   My attempt was to define a map, $\varphi:\mathbb{Z}[i] \to \mathbb{Z}/10\mathbb{Z}$ and show that the kernel is the ideal generated by $\langle{3-i\rangle}$. But I couldn't think of such a map. Anyhow, any ideas would be helpful. Why is "bicycle" pronounced differently from other obviously related words? Methods to work around the problem of missing data in machine learning Virtually any database we want to make predictions using machine learning algorithms will find missing values ​​for some of the characteristics.  There are several approaches to address this problem, to exclude lines that have missing values ​​until they fill with the mean values ​​of the characteristics.  I would like to use for a somewhat more robust approach, which would basically run a regression (or another method) where the dependent variable (Y) would be each of the columns that have missing values ​​but only with the rows of the table that contain all the data , and predict the missing values ​​with this method, complete the table by the table and move to the next 'column' with missing values ​​and repeat the method until everything is filled.  But that gives me some doubts.  Why any column start? I believe that the one with the smallest missing values ​​until the one with the most  Is there any threshold of missing values ​​that is not worth trying to complete it? (for example, if this characteristic only has 10% of the values ​​filled would not it be more interesting to exclude it)  Is there any kind of implementation in traditional packages or other methods that are robust to missings?

I am sketching the architecture for a set of programs that share various interrelated objects stored in a database. I want one of the programs to act as a service which provides a higher level interface for operations on these objects, and the other programs to access the objects through that service.  I am currently aiming for Python and the Django framework as the technologies to implement that service with. I'm pretty sure I figure how to daemonize the Python program in Linux. However, it is an optional spec item that the system should support Windows. I have little experience with Windows programming and no experience at all with Windows services.  Is it possible to run a Python programs as a Windows service (i. e. run it automatically without user login)? I won't necessarily have to implement this part, but I need a rough idea how it would be done in order to decide whether to design along these lines.  Edit: Thanks for all the answers so far, they are quite comprehensive. I would like to know one more thing: How is Windows aware of my service? Can I manage it with the native Windows utilities? What is the equivalent of putting a start/stop script in /etc/init.d? How would I identify what's causing my Mac to permanently hang on shutdown? Whenever I try to shutdown or reboot my Mac (Macbook Pro 15" Retina late 2013, OS X 10.11.3) it closes all programs like normal and then it goes into that black screen with the progress bar. When it gets to about halfway it permanently hangs and won't ever finish rebooting. I looked at the log viewer and couldn't find anything in particular. Is there a way to monitor a shutdown more closely and find out what's causing it to get stuck? How to create a custom "confirm" & pause js execution until user clicks button? Ok, I'm doing a bunch of RIA/AJAX stuff and need to create a "pretty", custom confirm box which is a DIV (not the built-in javascript confirm). I'm having trouble determining how to accomplish a pause in execution to give the user a chance to accept or decline the condition before either resuming or halting execution. (depending upon their answer)   So here's the general flow of logic I'm dealing with:   User selects an item from dropdown and clicks button. In client-side javascript eventhandler for button, I need to check a (this is the key) SERIES of conditions for the item they chose in dropdown.  These conditions could possibly result in not showing any confirmation at all or possibly only some of the conditions may evaluate to true which means I'll need to ask the user to accept or decline the condition before proceeding. Only one confirmation should be show at a time.   To demonstrate the logic:  function buttonEventHandler() {  if (condition1) {   if(!showConfirmForCondition1) // want execution to pause while waiting for user response.      return; // discontinue execution }  if (condition2) {   if (!showConfirmForCondition2) // want execution to pause while waiting for user response.       return; // discontinue execution }  if (condition3) {   if (!showConfirmForCondition3) // want execution to pause while waiting for user response.       return; // discontinue execution }  ...   }    If anybody has dealt with this challenge before and found a solution, help would be greatly appreciated. As a note, I'm also using the MS Ajax and jQuery libraries although I haven't found any functionality that may already be included in those for this problem. Splitting a string into words and punctuation Prove that $\int_0^\infty \frac{x\,\log x}{(1+x^2)^2} = 0$ I have been asked to prove that $$\int_0^\infty \frac{x\,\log x}{(1+x^2)^2}\,dx = 0$$  I tried proceeding as follows: \begin{align} \int_0^\infty \frac{x\,\log x}{(1+x^2)^2}\,dx &amp;= \int_0^1 \frac{x\,\log x}{(1+x^2)^2}\,dx + \int_1^\infty \frac{x\,\log x}{(1+x^2)^2}\,dx \\ &amp; = \int_0^1 \frac{x\,\log x}{(1+x^2)^2}\,dx + \int_{u=1}^0 \frac{u\,\log u}{(1+u^2)^2}\,du\quad (\text{where }u=1/x) \\ &amp;= \int_0^1 \frac{x\,\log x}{(1+x^2)^2}\,dx - \int_0^1 \frac{u\,\log u}{(1+u^2)^2}\,du \\ &amp;=^? \int_0^1 0 \,dx \\ &amp;= 0 \end{align}  But I think that I should first show that the improper integral $\int_0^1 {x\,\log x}/{(1+x^2)^2}\,dx$ is convergent.  Do I need to show it? If yes, how to do so?  (I have been taught basic methods such as comparison, limit comparison and Dirichlet test.) Daily Ubuntu base update I am getting Ubuntu base update almost every day. This seems strange to me. What am I missing?   (I am using Ubuntu 14.04 LTS) Is "funnest" a word?
