13,899,304 | 0 | <p>This is a typical computer vision task (it might even be AI-complete), so it's not easy. However, there's an excellent opensource C++ library called <a href="http://opencv.org" rel="nofollow">OpenCV</a> which works well with iOS. I even found a <a href="http://www.aishack.in/2010/07/tracking-colored-objects-in-opencv/" rel="nofollow">tutorial</a> about detecting a colored object.</p> <p>The basic algorithm is, by the way, something like this: go through each pixel and see if it's red or not (you can do this by comparing it agains some kind of threshold value of the red, green and blue components). If this is done, grab the pixels which were good and figure out where the continuous area they're in is. A method for this would be counting the pixels, then assuming they form a circle, then dividing their number by pi and getting the square root - this would tell you the radius of the circle, that you can double for obtaining its diameter ("width").</p> |
38,764,090 | 0 | How to open a pop-up using JSF without it being blocked by the browser <p>I'm working on a PrimeFaces 6.0, JSF 2.2 (Mojarra 2.2.7) application.</p> <p>I need to load a web page from an external site and highlight a DOM node. My approach is to create a JavaScript function to open a pop-up window, load the web page through a servlet (to avoid cross domain issues) and highlight the node. The parameters I send to my function are generated in a managed bean.</p> <p>I tried to do so in two different ways:</p> <ol> <li>Using <code>RequestContext.getCurrentInstance().execute("myFunction(...)")</code> in my action (yes, I'm using PrimeFaces).</li> <li>Using <code>oncomplete="#{myBean.myJsCall}"</code> on my command button.</li> </ol> <p>Both ways the call is executed and the call is correct, but I run into my browser's (Chromium) pop-up blocker:</p> <p><img src="https://i.stack.imgur.com/hNX6Y.png" alt="The following pop-ups were blocked on this page"></p> <p>Is there a way to open pop-ups in JSF or specifically in PrimeFaces without them being blocked?</p> <p>This is not really relevant, but this is the simplified version of my JavaScript function.</p> <p>I developed this script using plain HTML and JS. There it was opening the pop-up without the blocker interfering. Also, when pasting the call into the console when running the JSF application, the pop-up is opened.</p> <pre><code>function myFunction(url, selector) { var popup = window.open("", "popup", "height=500,width=700"); var req = new XMLHttpRequest(); req.open("GET", url, true); req.onreadystatechange = function() { if (req.readyState === XMLHttpRequest.DONE) { popup.document.open(); popup.document.write(req.responseText); popup.document.close(); popup.document.addEventListener( "DOMContentLoaded", function() { /* Some code highlighting the selector */ }, false ); } } req.send(); } </code></pre> |

All the images are in same folder. Some works and some does not. I myself have Chrome developers edition.</p> <p>I am pretty sure all images were uploaded fine. I have chrome Version 43.0.2357.134 dev-m and when I install it from chrome webstore, it works fine.

13,604,393 | 0 | <p>If you look closely, you'll see that the bars for the first and the fourth items are drawn at the same positions and overlap.</p> <p>The fundamental problem is that the code is using the data itself (which is duplicated) to identify individual elements. If you want to have different elements with the same data values, you'll need to give them unique identifiers so that the code is able to distinguish between them. The scales in the code are set up such that the same input value will map to the same output value, i.e. if you have the same name, the bars will be drawn at the same position.</p> <p>One way of solving this problem would be to use a unique ID as input to the scale functions and then a formatter to make the labels from this ID.</p> |

Implement some easy if-else statements to set the appropriate value of the sorting property.</p> <p>When adding this column to the grid just make it hidden and sort on that column.</p> <p>Possibly a less elegant solution than the one proposed by najmeddine, but it works.</p> |

The answer is a simple yes or no. If the answer is 'yes,' the visitor is categorized under 'Prior Visitors' in our calculations; if it is no, the visitor is categorized under 'First Time Visitors.' Therefore, in your report, visitors who have returned are still only counted once.</p> </blockquote> <p>Piwik <a href="http://piwik.org/faq/general/#faq_43">FAQs</a>:</p> <blockquote> <p><strong>How is a 'unique visitor' counted in Piwik?</strong></p> <p>Unique Visitors is the number of visitors coming to your website; Unique Visitors are determined using first party cookies. If the visitor doesn't accept cookie (disabled, blocked or deleted cookies), a simple heuristic is used to try to match the visitor to a previous visitor with the same features (IP, resolution, browser, plugins, OS, ...). Note that by default, Unique Visitors are available for days, weeks and months periods, but Unique Visitors is not processed for the "Year" period for performance reasons. See how to enable Unique Visitors for all date ranges.</p> </blockquote> <p>They both use cookies to determine uniques, but both go about it calculating them in different ways.

21,358,311 | 0 | <p>OK, I don't know if I am really understanding the issue but I will do my best to answer and give a solution. Basically: on your "first" (old) site, you had a menu, and now you want to remake it in Wordpress, and style it so it looks and feels as good as the old one.</p> <p>No problem. On the backend of Wordpress, go to Appearance > Menus and create a new menu. Name it "header-menu" if you want. Put any of the new pages you've made in WP into it, or just make custom links to the pages you want (#page2, <a href="http://www.google.com" rel="nofollow">http://www.google.com</a>, etc).</p> <p>Now back on your .php page, put this code you had in the header</p> <pre><code><?php wp_nav_menu( array( 'theme_location' => 'header-menu', 'container_class' => 'main_menu' ) ); ?> </code></pre> <p>into the main body of the page (maybe in the main-menu div?). It outputs the menu "header-menu" so it should be inside the page html. This might have contributed to the "can see but can't click it" problem. I don't think you need to mess with anything in functions.php to get a menu working. After you have it on the page, just take a look and style the css how you want.</p> |

20,598,295 | 0 | DSP - Group Delay of an IIR filter <p>I need to write a program in order to filter a signal for 0.8-3 Hz. Even though I have a working FIR filter this one takes too long and I've decided to change to an IIR filter. I've designed one myself using fdatool in Matlab and I've got the NUM and DEN. The improvement in time would be quite good (the FIR was 125 taps and this one's order is 12). The next step was to move to the C implementation and I've found this nice website <a href="http://iowahills.com/Example%20Code/IIRNthOrderImplementation.txt" rel="nofollow noreferrer">http://iowahills.com/Example%20Code/IIRNthOrderImplementation.txt</a> .</p> <p>The problem is that in their code there is a parameter I just don't understand and that is NumSigPts. </p> <pre><code>void RunIIRPoly( double *Signal, double *FilteredSignal, int NumSigPts) { int j, k, N; double y, Reg[100]; for(j=0; j<100; j++)Reg[j] = 0.0; // Init the delay registers. for(j=0; j<NumSigPts; j++) { // Shift the delay register values. for(k=N; k>0; k--)Reg[k] = Reg[k-1]; // The denominator Reg[0] = Signal[j]; for(k=1; k<=N; k++)Reg[0] -= DenomCoeff[k] * Reg[k]; // The numerator y = 0; for(k=0; k<=N; k++)y += NumCoeff[k] * Reg[k]; FilteredSignal[j] = y; } } </code></pre> <p>In the description they say </p> <blockquote> <p>This particular filter has a nominal group delay of 4 so we set NumSigPts to at least 1000 + 2*4</p> </blockquote> <p>How can I find the group delay of my filter. Does it have anything to do with the filter's order? The signal I filter is continuously provided so my exact question would be what is the minimum size of the signal in order to begin filtering?</p> <p>Later edit:</p> <p>So today I had some attempts with this IIR filter, but still haven't managed to get some good results.

To access each pixel I call all_frames[frame_number][pixel_number].</p> <p>The code I came up with following the website mention above is:</p> <pre><code>void ApplyIIR ( float **all_frames, float *num, float *den, int frame_number, float *filter_Xs, int w, int h) { float Reg[FILTER_ORDER]; for (int i=0; i< (width*height) ; i++) { //go pixel by pixel for(int j=0; j<FILTER_ORDER; j++) //init regs Reg[j] = 0.0; float final_X=0; for(int l=0; l< FILTER_ORDER+ DELAY ; l++) { // not sure how to set DELAY for(int k=FILTER_ORDER-1; k>0;k--) Reg[k] = Reg[k-1]; Reg[0] = all_frames[frame_number][i]; //get pixels one by one for(int k=1; k<FILTER_ORDER;k++) Reg[0] -= den[k]* Reg[k]; for(int k=0;k<FILTER_ORDER;k++) final_X += num[k] * Reg[k]; if(frame_number == 0) //go through all the frames frame_number = FILTER_ORDER - 1; else frame_number--; } filter_Xs[i] = final_X; } } </code></pre> <p>FILTER_ORDER is set to 13, since num and den have 0-12 values.</p> <p>Am I on a completely wrong path?</p> |
4,476,244 | 0 | <p><em>This is another parenthetical note.</em></p> <p>As <a href="http://stackoverflow.com/questions/2982276/what-is-a-context-bound-in-scala/2983376#2983376">Ben pointed out</a>, a context bound represents a "has-a" constraint between a type parameter and a type class. Put another way, it represents a constraint that an implicit value of a particular type class exists.</p> <p>When utilizing a context bound, one often needs to surface that implicit value. For example, given the constraint <code>T : Ordering</code>, one will often need the instance of <code>Ordering[T]</code> that satisfies the constraint. <a href="http://stackoverflow.com/questions/4373070/how-do-i-get-an-instance-of-the-type-class-associated-with-a-context-bound/4373153#4373153">As demonstrated here</a>, it's possible to access the implicit value by using the <code>implicitly</code> method or a slightly more helpful <code>context</code> method:</p> <pre><code>def **[T : Numeric](xs: Iterable[T], ys: Iterable[T]) = xs zip ys map { t => implicitly[Numeric[T]].times(t._1, t._2) } </code></pre> <p>or </p> <pre><code>def **[T : Numeric](xs: Iterable[T], ys: Iterable[T]) = xs zip ys map { t => context[T]().times(t._1, t._2) } </code></pre> |

9,204,080 | 0 | <p><strong>UPDATE</strong></p> <p>I did a bit more investigation of the problem and you can find more detailed <a href="http://podlipensky.com/2012/02/how-to-check-if-browser-caching-disabled/" rel="nofollow">answer in my recent post</a> Note, the solution described below (initially) is not cross browser solution.</p> <p>Not sure if it helps, but you can try the following trick: 1. Add some resource to you page, let's say it will be javascript file <code>cachedetect.js</code>. 2. The server should generate <code>cachedetect.js</code> each time someone request it. And it should contain cache-related headers in response, i.e. if browser's cache is enabled the resource should be cached for long time. Each <code>cachedetect.js</code> should look like this:</p> <pre><code>var version = [incrementally generated number here]; var cacheEnabled; //will contain the result of our check var cloneCallback;//function which will compare versions from two javascript files function isCacheEnabled(){ if(!window.cloneCallback){ var currentVersion = version;//cache current version of the file // request the same cachedetect.js by adding <script> tag dynamically to <header> var head = document.getElementsByTagName("head")[0]; var script = document.createElement('script'); script.type = 'text/javascript'; script.src = "cachedetect.js"; // newly loaded cachedetect.js will execute the same function isCacheEnabled, so we need to prevent it from loading the script for third time by checking for cloneCallback existence cloneCallback = function(){ // once file will be loaded, version variable will contain different from currentVersion value in case when cache is disabled window.cacheEnabled = currentVersion == window.version; }; head.appendChild(script); } else { window.cloneCallback(); } } isCacheEnabled(); </code></pre> <p>After that you can simply check for <code>cacheEnabled === true</code> or <code>cacheEnabled === false</code> after some period of time.</p> |

37,380,186 | 0 | <p>There are a <em>ton</em> of different use cases for balanced BSTs and I can't possibly list all of them here, but here are a few good use cases:</p> <ol> <li><p>BSTs support <em>range queries</em>, where you can ask for all entries between two values, efficiently. Specifically, in a BST with n entries, if you perform a range query where k elements will be returned, the runtime is O(log n + k). Compare that to, say, using a hash table, where the runtime would be O(n). This can be used if you're interested in doing time series analysis of a set of data and want to explore data in certain ranges.</p></li> <li><p>BSTs support <em>successor and precedecessor</em> queries. Given a BST, you can ask for the smallest element greater than some value or for the largest element less than some value in time O(log n). Collectively, this lets you find the element in a BST that's closest to some target value in time O(log n), which can be useful if you're getting noisy data and want to map it to the closest entry in your data set. Compare this with hash tables, where this would take time O(n).</p></li> <li><p>BSTs are <em>worst-case efficient</em>. Many common types of binary search trees, like red/black trees and AVL trees, give worst-case guarantees on the costs of their operations. Contrast this with a hash table, where queries are <em>expected</em> to take constant time, but can degrade with a bad hash function or just due to bad luck. Additionally, every now and then a hash table has to rehash, which can take a while, but red/black trees and AVL trees don't have cases like these. (There are some types of balanced BSTs like splay trees and scapegoat trees that aren't worst-case efficient, but that's a different story.)</p></li> <li><p>BSTs give easy access to the <em>minimum and maximum values</em> in time O(log n), even if insertions and deletions are intermixed. Hash tables can't support these operations.</p></li> <li><p>BSTs support <em>ordered iteration</em>, so if you have an application where you want to view the data in sorted order, you get it "for free" with BSTs. One example of this would if, for example, you were loading student data and wanted to see the scores in sorted order. Hash tables don't support this - you'll have to pull out the data and sort it to get it back in sorted order.</p></li> <li><p>BSTs can be <em>augmented</em>. If you take an algorithms course, you'll probably learn about a technique called tree augmentation in which you can add extra information in each node of the BST to solve a ton of problems much faster than it would initially appear possible to do. For example, you can augment BSTs to instantly be able to read off the median element, or the closest pair of points, or to solve many algorithmic problems efficiently when the underlying data is changed. Hash tables don't support these operations.</p></li> <li><p>BSTs support <em>efficient split and join</em>. Red/black trees and splay trees have the interesting property that, given two trees where all the keys in one are less than the keys in the other, the trees can be combined together into a single tree in time O(log n) - much faster than visiting all elements of the tree! You can also split any red/black tree or splay tree into two smaller trees by partitioning the tree into "elements less than some value" or "elements more than some value" in time O(log n). It's not trivial to do it, but it's possible. The time bounds on the corresponding operations on a hash table are O(n).</p></li> </ol> <p>If I think of anything else, I'll update this list. Hope this helps!</p> |

17,846,713 | 0 | <p>I have been a devoted user of <a href="http://jmeter.apache.org/" rel="nofollow">Apache JMeter</a> for the past decade and it does offer helpful web load testing functionality for free. Here are some pointers that may help determine if JMeter is right for you:</p> <ol> <li>Apache JMeter is a Java application, so it does have upper limits on resources (memory, sockets, threads). These resources can often be increased or consumption optimized (standard JVM args or jmeter.properties file) for better performance under heavy load testing.</li> <li>When capturing scripts using the "HTTP Proxy Server" node, make sure that you have a "User Defined Variables" node created and populated with your name/value pairs for the test. This will trigger a variable substitution in the proxy server. This is invaluable when you want to parameterize the script.</li> <li>As with tree based structures, position determines scope. Make sure that you isolate actions under the proper node or else they will execute for everything at the same scope. </li> <li>For simulated delays, I have had a good run with the "Uniform Random Timer" where you can specify a lower and upper limit.</li> <li>For validation, the "Response Assertion" is helpful for raw strings and regular expressions.</li> <li>For variable extraction, the "Regular Expression Extractor" allows you to extract a value from a page and reference it in a variable for the rest of the test. Node scope appears to be treated as global for these extractors.</li> <li>When watching the test, "Aggregate Graph" is helpful. "View Results Tree" is useful when troubleshooting, but adds extra memory usage to tests and can cause heavy tests to fail. Note that if you save the results on a listener node, you can reload those results in the control at a later time. Also, if you highlight the table in "Aggregate Graph" or "Aggregate Report", you can paste the results into Excel directly. Very helpful for reporting. </li> </ol> <p>Hopefully this gives you an idea of some of the value and gotchas with Apache JMeter. </p> |

3,305,976 | 0 | <p>The short answer is no, not at this time. The iPhone/iPad/iPod Touch work nativly with the Apple HTTP Adaptive segmented streaming protocols. MMS (Windows Media) streams are not compatible with "i" devices and will not play. You will need to look into encoding your video with this other format. <a href="http://developer.apple.com/iphone/library/documentation/networkinginternet/conceptual/streamingmediaguide/introduction/introduction.html" rel="nofollow noreferrer">Check out the Apple specs</a> for a full description of the protocol. Future versions of Windows Media Services (4.0) are claiming that they will support the Apple protocols but this is only a preview/beta at this time and may not truly support the Apple specs.</p> <p>If your trying to do ondemand iPhone video, you can utilize a service such as Encoding.com to pre encode your files in the adaptive segmented format for your users to view. For live encoding, Telestream has a product called Wirecast which can encode in a h.264 Apple approved baseline format which can be sent to a service such as Akamai, Multicast Media, or Wowza Server for distribution to your clients.
