How do I compare strings in Java?
Can Recovery Mode install OS X onto a blank SSD? I want to install a new Solid State Drive (SSD) into the Mac. Can I just build in the SSD, start the MacBook in Recovery Mode and install OS X from there on?  After reading a lot on the internet I still have some doubts…  My HDD crashed, I can't repair it using disk utility or the fsck methods as mentioned on the internet.  According to  it should be possible.  I know how to replace the HDD with the SSD. I would go for the Samsung 850 EVO SSD - 500GB. My Mac is a MacBook Pro Mid 2012, model A1278. How do I bridge network interfaces? I have a laptop running 11.10 with 2 network interfaces, wired and wireless.  Wireless interface connects to the router with DHCP and connects to the internet. Wired interface is connected to a switch. I want the computers on the switch to get their IP addresses from the router not my laptop.     How would I go about setting this up? Bridging the interfaces? Why is the top bar not changed on Stack Exchange, Area 51 and Ask Ubuntu? Does there exist a magical shell piping which would allow easily to grep through bunch of .gz log files without needing to extract them somewhere?  .gz files are Apache logs, result of log rotation. I'd like to quickly check how often certain URIs are accessed in the past. Where Can I Give Feedback on Ubuntu? I'm running Ubuntu 11.04 Beta 2. Is there a way, or a place, to give feedback on this system? Not file bugs, just give feedback. How to change an input button image using CSS So, I can create an input button with an image using &lt;INPUT type=&quot;image&quot; src=&quot;/images/Btn.PNG&quot; value=&quot;&quot;&gt;  But, I can't get the same behavior using CSS. For instance, I've tried &lt;INPUT type=&quot;image&quot; class=&quot;myButton&quot; value=&quot;&quot;&gt;  where &quot;myButton&quot; is defined in the CSS file as .myButton {     background:url(/images/Btn.PNG) no-repeat;     cursor:pointer;     width: 200px;     height: 100px;     border: none; }  If that's all I wanted to do, I could use the original style, but I want to change the button's appearance on hover (using a myButton:hover class). I know the links are good, because I've been able to load them for a background image for other parts of the page (just as a check). I found examples on the web of how to do it using JavaScript, but I'm looking for a CSS solution. I'm using Firefox 3.0.3 if that makes a difference. How could they return the Infinity Stones in their "raw" form? There is this one little thing that I don't quite get at the end of Avengers: Endgame.  After Thanos was defeated, Captain took the stones back to where they were originally taken to "correct" the timeline. However we see that Cap has the 6 stones in their "Raw" form, but that is not how all of them were taken.   For example in 1970 Tony didn't take the Space Stone but the Tesseract, so I assume they extracted the Space Stone in the present (by breaking the Tesseract like Thanos in the Infinity War movie?).   So how could Cap return the stone to the rightful place when he actually needed to return the Tesseract? Or am I missing something here...   The same goes for the Mind Stone, which was inside the Gem on the Staff Loki had in the first Avengers movie. Ubuntu 18.04 Dock mouse hover tooltips - how to disable? I need to know if it is possible and how to disable the Ubuntu 18.04 Dock tool-tips for mouse hover the pinned application. How to convert a HEIF/HEIC image to JPEG in El Capitan? Using Xpath With Default Namespace in C# I've got an XML document with a default namespace. I'm using a XPathNavigator to select a set of nodes using Xpath as follows:     XmlElement myXML = ...;   XPathNavigator navigator = myXML.CreateNavigator(); XPathNodeIterator result = navigator.Select("/outerelement/innerelement");   I am not getting any results back: I'm assuming this is because I am not specifying the namespace. How can I include the namespace in my select? I'd say Microsoft have a way of bending the rules and I know that McLaren have won the championship. While this sounds strange, I believe it is correct English (sorry, I'm not native).   But when it's a small company, would you still use it this way? Is a company always plural, or are small companies singular? I.e., would you say Bakery Johnson makes fine bread or Bakery Johnson make fine bread? Is it My book seller, Woody's, have moved or is it has moved? I don't have any knowledge in hardware and would like to know which RAM should I buy for my laptop.  How do I discover what RAM I need &amp; how much my machine can take?  I have a Razer Blade 15 (RZ09-02705F76) 2018 but don't know if there is a specific type or format of RAM that suits it and don't know where to find this information. I have heard from  that stable orbits (ones that require a large amount of force to push it significantly out of it's elliptical path) can only exist in a three spatial dimensions because gravity would operate differently in a two or four dimensional space. Why is this? Cannot install WPS Office I'm using Ubuntu GNOME 16.10 and was trying to install WPS Office. I tried to install using software centre But it wasn't installing without giving any error logs. Then I opened it with Gdebi installer. Here is what I saw.    I have already trying enabling multiverse repositories.  Edit: I have downloaded the amd64 package from the WPS official site, but even now installing through terminal I still get the missing dependencies error. Does $x^2 - y^2 = 12345678$ (x,y are integers) have any solutions? Installing Ubuntu on a SSD Going to install Ubuntu 10.10 on new intel x25M 80GB SSD. It will be fresh install. I have been googling for past few days and getting overwhelming articles/blogs/Q&amp;As. One particularly very useful being:     But with so many suggestions and differences of opinions (on different links) this simple OS install process seems to be daunting task to me and I really want to stick with Ubuntu (although have used for very short period of time).  Can someone help me by answering few questions (yes, they are repeated because I couldn't comprehend the answers elsewhere)   Which file system (ext2/3/4 or something else)? (consider SSD life) Can it be changed after installation? Should I partition the disk? (as we do in traditional HDD) for now, no plan of dual booting. Only Ubuntu will live on scarce space of 80GB SSD. I have 2 GB RAM, should i still allocate swap space (if I don't allocate swap space, can I still hibernate the machine)? will swap space impact SSD life? Should I consider putting additional 1GB RAM to avoid swap space? What is partition aligning? Is it needed to be done before installing the Ubuntu OS or can be done later?   Intended usage - heavy browsing, programming, regular video/music and some other non-CPU/RAM-intensive programs.

I don't want to have to jump through \setcounter hoops to do this. That is, I want something like  \begin{enumerate}   \item First   \item Second   \item[8] Eighth!   \item Ninth!   \item[4] Fourth \end{enumerate}   to give the following Good output, instead of the Bad output:    A minimum working example follows.  \documentclass{article} \usepackage{enumitem} % preferably something compatible with this guy \begin{document}  Good:  \begin{enumerate}   \item[1.] First   \item[2.] Second   \item[8.] Eighth!   \item[9.] Ninth!   \item[4.] Fourth \end{enumerate}  Bad:  \begin{enumerate}   \item First   \item Second   \item[8] Eighth!   \item Ninth!   \item[4] Fourth \end{enumerate}  \end{document}   It should be noted that I don't want to have to specify the period afterwards, in case my list using a different numbering, e.g. Roman. Compatibility with enumitem is preferred, but not required.  What is the correct way of going about this? Java conditional compilation: how to prevent code chunks from being compiled?
