How to install Realtek drivers from GitHub
Realtek RTL8723BE Wi-Fi incredibly weak
My exterior door deadbolt has gotten stuck - it'll open with the lever but not the key. By spraying WD-40 inside the lock, I've been able to get it to work but it's very stiff. I'd like to remove the lock and inspect the inside, either to clean/lube it or replace it. But I can't figure out how to remove the lock; there's no obvious way to do this. (I'm used to seeing two screws on the inside of the deadbolt, usually under the lever arms when it's horizontal.)    How do I remove this? I can loosen the cover plate on the inside but it doesn't do anything other than rotate a few degrees. How can I handle the warning of file_get_contents() function in PHP? Why the switch statement cannot be applied on strings? Compiling the following code and got the error of type illegal.  int main() {     // Compilation error - switch expression of type illegal     switch(std::string("raj"))     {     case"sda":     } }   You cannot use string in either switch or case. Why? Is there any solution that works nicely to support logic similar to switch on strings? Add new alias to Gmail without SMTP (forwarding-only address) I used to be able to go to Accounts and Import → Add another email address you own and add an email account that's only a forwarding address. That is, it's not a mailbox and I don't have SMTP access to it.  Gmail would send me a confirmation email to that address, I'd confirm it's mine, and done. Now it only gives me the option to add SMTP credentials.  Did they stop supporting the previous method? Is there any other way I can get that option back? How to overcome Acrobat Reader error 131 with a pdfLaTeX doc? I'm generating a PDF document with pdflatex (more precisely, latexmk invoked from TexMaker 3.4. My LaTeX install is TeXLive 20120719). I can read the document fine in Okular and Gmail's attachment preview, but a colleague that runs Acrobat Reader on Windows reports: "There was a problem reading this document (131)".  EDIT: The error disappears when using \usepackage[demo]{graphicx}, which puts black boxes instead of the real images. They are all PDFs, PNGs and JPGs. Instead of using demo, I added the code for a \demoincludegraphics command, which makes the file work in Reader when using it to replace the logo in the headers, as shown below. But enabling it (using \includegraphics instead of \demoincludegraphics) and removing everything else also works in Reader! There is some strange global interaction that makes the file appear broken to Reader when enabling all the graphics...

Extracting text from HTML file using Python Constructing a HoTT proof term of 1≠0 As an exercise in HoTT basics, I am trying to construct a term that has the type $Id_{Nat}(S(O),O)\to\bot$. If this were a Coq proof, I'd be done after a single inversion on the premise, as the impossible identity would leave zero cases to consider. I guess I could do something similar here, but I'm not sure how. What would be an HoTT term that has the type? How can I make two columns in two columns How can I make two columns in two columns same as in the picture? Center a column in align I have the following type of code in my document:  \begin{align*}        (-m)+m &amp; \stackrel{\mathrm{Ax 1.1 (i)}}{=}  m+(-m)\\   &amp;\stackrel{\mathrm{Ax 1.4}}{=}  0 \   I want to align on the = but that is complicated by the fact that there is something hovering over it.  It would seem to be easier to align their centers (no matter what, that is where the = will be).  How can I center a column in align (or align* to be honest, I am not that clear on the difference) What is the reasoning behind restricting the number of migration paths? On the religion and culture stackexchange sites, many, many users will initially ask a question in a place that's kind of off-topic there, but are fully on-board elsewhere.    Christianity.SE, for example, gets a lot of general philopsophical questions that would be better on Philosophy, historical questions that might be better on History.SE, and hermenutical questions that are better on BH.SE.  It is, however, unreasonable in my mind for a user with a question to be required to have domain expertise on which sub-site each has. Indeed, even amongst users with a high amount of knowledge, there can be disagreement.  Likewise, , but as just about every one of those is in beta, the user would have to be very saavy (or would have to find that post) in order to nail it every time.  That said, recommending that a question be moved is much harder than it needs to be.  I have seen business rule logic that says, for example,    migration paths only exist to graduated sites (ergo politics, money, history, and quantitative finance wouldn't qualify) migration paths seem to be limited to 5.   Anything not on a migration path requires a moderator (and not just a high rep user) to get involved.  So, what is the reasoning behind this?  Note, I'm not asking for a solution (although the obvious solution would be to allow migration paths to any established site, beta or not, i.e. a VTC as off topic b/c it belongs on another site should allow you to pick any other site) - I just want to understand the business purpose in restricting migration paths to a small, predefined number for everyone other than a mod. Ubuntu 14.04 System Logging I've set up an Ubuntu 14.04 Server (from an Ubuntu 12.04 Server) but today I wanted to look in the auth.log but this file is not used. It seems that ´syslog´ was deleted.  How does Ubuntu 14.04 log? I need this for a server.  Thank you. Iterate enum values using java generics Symbolic Link: Creating link from "NTFS Partiton" to ~/Desktop I have start learning Selenium WebDriver, but i am confused between Java and Python. Which language should i choose? I do have basic ideas of Core Java but haven't wrote a single piece of code with python.  So please suggest me which is the better language for Selenium WebDriver? Sarrus Rule with LaTeX Is there a way to create a new command with 9 arguments ({a_{11}},{a_{12}},{a_{13}},{a_{21}},{a_{22}},{a_{23}},{a_{31}},{a_{32}},{a_{33}}) that has as output a matrix with the Sarrus Rule? For instance: to obtain     just use the command that we will call sarrus:  \sarrus{-k}{k-1}{1}{0}{k-1}{k}{2}{0}{1}.   If it is possible i want to use the command sarrus in math mode just like matrix for istance. Holomorphic function $f:B(0,1) \to B(1,4)$ with $f(0)=3$ and $f(\frac{1}{2})=1$ Problem  Find all holomorphic functions $f:B(0,1) \to B(1,4)$ that verify $f(0)=3$ and $f(\frac{1}{2})=1$.  I have no idea how to attack this problem,since it comes after an exercise related to Schwarz lemma, I thought that maybe the idea is to somehow apply the lemma in this problem as well, but if that is the case, I don't know how could I use it. I would appreciate suggestions.
