40,945,088 | 1 | What does numpy.cov actually do <p>I am new to python and to linear algebra and I have a question about covariance of a matrix.</p> <p>I have a 21 by 2 matrix, where the first column represents the average score(from 0 to 10) of the video games released that year and second columns are years ranging from 1996 to 2016.</p> <p>I was playing around with the data and I noticed that by doing np.cov(X) I got a very interesting graph. I will list the graph below. It is my understanding that covariance shows the dependence among the variables in a dataset, but will it be correct to state that based on this covariance graph we can say that the average score of the games rises as the years rise ?</p> <p><a href="https://i.stack.imgur.com/llLT9.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/llLT9.jpg" alt="enter image description here"></a></p> <p>Thanks.</p> |

26,849,108 | 0 | <p>There are multiple things:</p> <ol> <li>The crash is caused by an exception and the crash report does not show the required <code>Last Exception Backtrace</code>.</li> <li>Symbolicating the main thread will only show you the <code>main.m</code> call in frame 12 and the uncaught exception handler in frame 2 of thread 0</li> <li>The crash report is written by an old version of <a href="http://plcrashreporter.org/" rel="nofollow">PLCrashReporter</a> (identified by the two <code>[TODO]</code> texts on top) or you are using another server for uncaught exceptions. As is, the crash report will not help you.</li> <li>You should use <code>atos</code> with the apps dSYM instead of the app binary. Using the app binary will never show you filenames or line numbers and will only show you class name and methods if you don't strip symbols from the executable. But you should strip them from the executable to keep the binary size as low as possible (saves 30-50%).</li> <li><p>The way you are calling <code>atos</code> is wrong. <code>0x7f68bb0 0x3017d000 + 84904</code> is not a valid option, and in fact your crash report doesn't even contain that. Instead you need to use only the first address after the binary name per frame. So for the following line:</p> <pre><code>2 Example 0x001ffe3b 0x4000 + 2080315 </code></pre> <p>You would use atos as follows:</p> <pre><code>`atos -arch -armv7 -l 0x4000 -o Example.app.dSYM 0x001ffe3b` </code></pre></li> </ol> <p>You should update your crash reporting SDK to use the latest PLCrashReporter version and make sure exceptions are shown properly in the report.</p> |

30,581,518 | 0 | <p>Here's a simple project using sockets and files to read to and write from that I did a while ago. Hopefully viewing this code will clarify the questions you have with your own code. Due to the time constraints, I didn't convert it to include the code snippets you've provided, but if you're still stuck with your own code after taking a look at mine, I'll see what I can do. </p> <p>A few things to note if you run this code:</p> <ul> <li>This project uses server and client GUIs that are a little messy (I'm not very good at designing GUIs), but the functionality should still be useful. </li> <li>You need to provide the same port number as a command line argument for both the server and client. You can do this in Eclipse via Run button dropdown -> Run configurations... -> arguments tab ->typing a port number (I used 12345) -> click run). Do this for both the server and client.</li> <li>Make sure to run the server before you run the client</li> <li>This example only reads from files. There's no writing functionality.</li> <li>Once the client has successfully started, type the name of the file you want to read from (ie: readfile1.txt) including the file extension.</li> <li>This uses relative path names starting from the root project directory so if your Users.txt file is in your src folder, you'd type "src/Users.txt".</li> <li>Type the file name in the client's input field at the top of the client GUI to have the entire contents of that file printed below. You can type as many file names as you want one at a time.</li> </ul> <p><strong>Server code</strong></p> <pre><code>import java.awt.BorderLayout; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.io.EOFException; import java.io.File; import java.io.IOException; import java.io.ObjectInputStream; import java.io.ObjectOutputStream; import java.net.ServerSocket; import java.net.Socket; import java.util.Scanner; import javax.swing.JFrame; import javax.swing.JScrollPane; import javax.swing.JTextArea; import javax.swing.JTextField; import javax.swing.SwingUtilities; public class FileServer extends JFrame { //main function public static void main(String[] args) { int port = Integer.parseInt(args[0]); //String file = args[1]; FileServer server = new FileServer(port); server.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); server.runServer(); } //FileServer class declarations private File file; //for this example, the file is stored in the root project directory and includes the file extension (ie: .txt, etc) private ServerSocket ss; private Socket connection; private JTextField field; private JTextArea displayArea; private int portNum; private ObjectOutputStream oos; private ObjectInputStream ois; public FileServer(int port) { super("Server"); //file = new File(f); //sent from client or done here? portNum = port; field = new JTextField(); field.setEditable(false); field.addActionListener( new ActionListener() { public void actionPerformed(ActionEvent event) { sendData(event.getActionCommand()); field.setText(""); } }); //ends addActionListener add(field, BorderLayout.NORTH); displayArea = new JTextArea(); add(new JScrollPane(displayArea)); setSize(500, 300);//size of JFrame setVisible(true); }//end constructor /** * code that executes the server obj.

14,289,505 | 0 | <p>20 million rows is not a lot for MySQL. Just index the zip/postal code and it will be fast. Way under 200ms fast. No need to split between tables. MySQL does get slow when the result set is large, but it doesn't seem like you would encounter that issue. MySQL will do just fine with hundreds of millions of records for basic queries like yours.</p> <p>You will need to adjust the MySQL settings so that it uses more memory. The default settings are pretty low. </p> <p>MySQL does support spacial indexes. So you could pull the longitude/latitude for the postal codes and use a spacial index to do proximity searches. Doesn't seem like you are looking for that though.</p> <p>If you want things really, really fast, go the route you were thinking of but use memcache or redis. You can use the zip/postal code as the lookup key. You would still need a persistant disk based data store to load the data from. I don't think memcache/redis is necessary, but it's an option.</p> |

10,573,130 | 0 | Implications of using std::vector in a dll exported function <p>I have two dll-exported classes A and B. A's declaration contains a function which uses a std::vector in its signature like:</p> <pre><code>class EXPORT A{ // ... std::vector<B> myFunction(std::vector<B> const &input); }; </code></pre> <p>(EXPORT is the usual macro to put in place _<em>declspec(dllexport)/</em>_declspec(dllimport) accordingly.)</p> <p>Reading about the issues related to using STL classes in a DLL interface, I gather in summary:</p> <ul> <li><p>Using std::vector in a DLL interface would require all the clients of that DLL to be compiled with the same <em>version</em> of the same compiler because STL containers are not binary compatible. Even worse, depending on the use of that DLL by clients conjointly with other DLLs, the ''instable'' DLL API can break these client applications when system updates are installed (e.g. Microsoft KB packages) (really?).</p></li> <li><p>Despite the above, if required, std::vector can be used in a DLL API by exporting <code>std::vector<B></code> like:</p> <pre><code>template class EXPORT std::allocator<B>; template class EXPORT std::vector<B>; </code></pre> <p>though, this is usually mentioned in the context when one wants to use std::vector as a <em>member</em> of A (http://support.microsoft.com/kb/168958).</p></li> <li><p>The following Microsoft Support Article discusses how to access std::vector objects created in a DLL through a pointer or reference from within the executable (http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q172396). The above solution to use <code>template class EXPORT ...</code> seems to be applicable too. However, the drawback summarized under the first bullet point seems to remain.</p></li> <li><p>To completely get rid of the problem, one would need to wrap std::vector and change the signature of <code>myFunction</code>, PIMPL etc..</p></li> </ul> <p>My questions are:</p> <ul> <li><p>Is the above summary correct, or do I miss here something essential?</p></li> <li><p>Why does compilation of my class 'A' not generate warning C4251 (class 'std::vector<_Ty>' needs to have dll-interface to be used by clients of...)? I have no compiler warnings turned off and I don't get any warning on using std::vector in <code>myFunction</code> in exported class A (with VS2005).</p></li> <li><p>What needs to be done to correctly export <code>myFunction</code> in A? Is it viable to just export <code>std::vector<B></code> and B's allocator? </p></li> <li><p>What are the implications of returning std::vector by-value? Assuming a client executable which has been compiled with a different compiler(-version). Does trouble persist when returning by-value where the vector is copied? I guess yes. Similarly for passing std::vector as a constant reference: could access to <code>std::vector<B></code> (which might was constructed by an executable compiled with a different compiler(-version)) lead to trouble within <code>myFunction</code>?

20,315,925 | 0 | Why should I use cookies other than for storing a session id? <p>For HTTP as far as I understand are two ways to store data belonging to a client and bring some kind of state into a otherwise stateless Browser-webcontainer-connection: 1) Data stored in cookies on the client-side - or 2) A session ID stored in a cookie and the associated data stored in a webcontainer on the server-side. When I compare these two possibilities I can't come up with a reason, why one should go the first way. But still, when I look at my browser's cookies, I see a lot of data stored in them. </p> <ul> <li>A webcontainer (like tomcat) can store arbitrary data together with a session id - A cookie is quite limited in size.</li> <li>Cookies are more vulnerable, since they are stored on the client's side. Keep data on the server-side is, as it looks for me, just more secure. </li> <li>Both, cookies and webcontainer-sessions, can define expiration dates.</li> <li>Both, browser and webcontainer, persist their data over restarts.</li> </ul> <p>Can anyone come up with a scenario where the use of cookies for storing session data has benefits or is even necessary?</p> |

15,557,209 | 0 | How do I store DatePicker Time in a SQLite database? Mine keeps crashing <p>I've created a simple record keeping application using various resources around the internet. I'm able to successfully store text data - however when I attempt to incorporate a <code>TimePicker</code> I end up crashing my entire app. I was instructed how to add this functionality in a previous post - but when I attempt to add fields for the timepicker data the entire app closes (and of course does not save the data) </p> <p><a href="http://stackoverflow.com/questions/15540395/how-do-i-store-timepicker-data-in-my-simple-record-keeping-app">How do I store TimePicker Data in my simple record keeping app?</a></p> <p>I was instructed (by the user above) to use the following:</p> <pre><code>CREATE TABLE ...... dtField date, tmpName Text..... </code></pre> <p>use following for saving date as text</p> <p>//sample date format - 2013-03-21 13:12:00</p> <pre><code>android.text.format.DateFormat.format("yyyy-MM-dd hh:mm:ss", dtDate.getTime()) </code></pre> <p>The first half of which I've implemented (I believe).

The suggestion by Robby Pond was helpful but I have a deeper issue with the (current) source code below. </p> <p>P.S.</p> <p>I know the error cannot be resolved to a type usually indicates there is a

9,400,418 | 0 | <p>The given XML namespaces (note: that are not "xmlns imports") are correct for JSF 2.x. However, in Facelets 1.x, which is to be used standalone in JSF 1.x projects, the XML namespace for JSTL is different, it should not contain the <code>/jsp</code> path.</p> <pre><code>xmlns:c="http://java.sun.com/jstl/core" </code></pre> <p>But if you're actually already using JSF 2.x (in future JSF 2.x questions please mention and tag accordingly), then you're probably using a servletcontainer which doesn't ship with JSTL included, such as Apache Tomcat. You'd need to download JSTL separately and drop it in <code>/WEB-INF/lib</code> folder. In that case the <code>xmlns:c="http://java.sun.com/jsp/jstl/core"</code> should work.</p> <h3>See also:</h3> <ul> <li><a href="http://stackoverflow.com/tags/jstl/info">Our JSTL tag wiki page</a></li> </ul> <hr> <p><strong>Unrelated</strong> to the concrete question, using JSTL in Facelets is definitely possible. You should only make sure that you really understand the lifecycle of tag handlers like JSTL in JSF. See also <a href="http://stackoverflow.com/questions/3342984/jstl-in-jsf2-facelets-makes-sense">JSTL in JSF2 Facelets... makes sense?</a> You could alternatively also just use Facelets' own <code><ui:repeat></code> tag instead of the <code><c:forEach></code>.</p> |

30,298,025 | 0 | How to use a data attribute from a target div as view param in a PrimeFaces ContextMenu outcome <p>I'm trying to do the following:</p> <ul> <li>From a simple collection of elements...</li> <li>Add a PrimeFaces ContextMenu...</li> <li>Have the first menu option forward to a new page...</li> <li>Pass a data attribute from the selected element as a view param.</li> </ul> <p>It all seems pretty straightforward, until I come to the last step, and I can't seem to find a way to get this to work.</p> <p>e.g.</p> <pre><code> <div class="group" data-group="GRP1"> ... </div> <div class="group" data-group="GRP2"> ... </div> <div class="group" data-group="GRP3"> ... </div> <p:contextMenu targetFilter="div.group"> <p:menuitem value="Edit" outcome="group.xhtml?group=GRP???"/> </p:contextMenu> </code></pre> <p>The divs are generated HTML and I don't really have much control over those, so probably need to do something with Javascript on the client side.</p> <p>I've tried to get hold of the group from the Javascript side, but I can't see how to bind a function to the beforeShow handler. I can see that if I can register the correct event handler then the PF code will pass me the event (from which I can get the target element and the data attribute):</p> <pre><code> // from PF menu.js if(this.cfg.beforeShow) { var retVal = this.cfg.beforeShow.call(this, e); if(retVal === false) { return; } } </code></pre> <p>But I'm not sure how to access this - if I just use inline event registration then I can only pass Javascript code not a reference to my function:</p> <pre><code> function doBeforeShow(menu, event) { var group = event.target.dataset['group']; } <p:contextMenu targetFilter="div.group" beforeShow="/* this is just executed JS not a bound function */"> </code></pre> <p>Anyway, even if I could get the group from the JS side, I'm not really sure what I'd do with it... probably store it somewhere and attach another handler to the p:menuitem so when it was selected it could modify the outcome before calling it?</p> <p>So I'm stuck! Anyone have any ideas on how I can get this to work?</p> <p>Thanks,</p> |
16,231,387 | 0 | Good way to clear nested Maps in Java <pre><code>public class MyCache { AbstractMap<String, AbstractMap<String, Element>> cache = new TreeMap<String, AbstractMap<String, Element>>(); public Boolean putElement(String targetNamespace, Element element) { ... } public void clear() { cache.clear(); } // is it better this way? public void deepClear() { for(AbstractMap<String, Element> innerMap : cache.values()) { innerMap.clear(); } cache.clear(); } } </code></pre> <p>Is it necessary to iterate over the values of the root map and clear all the maps nested in the root first, or is it enough to clear the outermost map? My main question is, if there is any difference in the memory consumption of the JVM between these two methods?</p> |

5,639,734 | 0 | <p>Stumbled upon this question and thought I would offer an alternative. If you run into trouble with popup blockers, you can use plain old HTML to launch a url in a new window/tab. You won't have as much control over that is displayed (scrollbars, toolbar, etc), but it works even if javascript is disabled and is 508 compliant:</p> <pre><code><a href="http://www.google.com/" target="_blank">Open new window</a> </code></pre> <p>You can read more about the various target attributes here: <a href="https://developer.mozilla.org/en/HTML/Element/a" rel="nofollow">https://developer.mozilla.org/en/HTML/Element/a</a></p> |
