35,835,296 | 0 | Automatically restore last saved document on application launch <p>I have a Core Data Document Based application written in swift and using storyboards. Whenever I build and launch the app, instead of automatically opening the last opened document(s), it will create a new document. What I want to be able to do is have the application automatically restore whatever documents were last opened on application launch, if they are available. How can I do this?</p> |

18,486,496 | 0 | <p>If you ultimately decide to move the cache outside your main webserver process, then you could also take a look at <a href="http://en.wikipedia.org/wiki/Consistent_hashing" rel="nofollow">consistent hashing</a>. This would be a alternative to a replicated cache.</p> <p>The problem with replicated caches, is they scale inversely proportional to the number of nodes participating in the cache. i.e. their performance degrades as you add additional nodes. They work fine when there is a small number of nodes. If data is to be replicated between N nodes (or you need to send eviction messages to N nodes), then every write requires 1 write to the cache on the originating node, and N-1 writes to the other nodes.</p> <p>In consistent hashing, you instead define a hashing function, which takes the key of the data you want to store or retrieve as input, and it returns the id of the server in the cluster which is responsible for caching the data for that key. So each caching server is responsible for a fraction of the overall keys, the client can determine which server will contain the sought data without any lookup, and data and eviction messages do not need to be replicated between caching servers.</p> <p>The "consistent" part of consistent hashing, refers to how your hashing function handles new servers being added to or removed from the cluster: some re-distribution of keys between servers is required, but the function is designed to minimize the amount of such disruption.</p> <p>In practice, you do not actually need a dedicated caching cluster, as your caches could run in-process in your web servers; each web server being able to determine the other webserver which should store cache data for a key.</p> <p>Consistent hashing is used at large scale. It might be overkill for you at this stage. But just be aware of the scalability bottleneck inherent in O(N) messaging architectures. A replicated cache is possibly a good idea to <em>start with</em>.</p> <p>EDIT: Take a look at <a href="http://infinispan.org/docs/5.3.x/faqs/faqs.html" rel="nofollow">Infinispan</a>, a distributed cache which indeed uses consistent hashing out of box.</p> |

20,834,720 | 0 | how to make an overlay of google maps stand on top of the zoom bar <p>So here is how I create an overlay (the standart way). Problem is, when I drag the map around, the overlay gets behind the zoom bar and other controls. I want those controls to go behind the overlay. I tried changing the z-index of the overlay but that doesn't work because parents of the overlay have low z-index. If I change z-index of the parents, the controls get hidden by the whole map. So the reason that changing z-index doesn't work is because overlay and zoom bar for example are in 2 different divs which themselves have z-index.</p> <pre><code><html> <head> <style type="text/css"> #map { width: 600px; height: 500px; } </style> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript"> var map; TestOverlay.prototype = new google.maps.OverlayView(); /** @constructor */ function TestOverlay(map) { this.setMap(map); } /** * onAdd is called when the map's panes are ready and the overlay has been * added to the map. */ TestOverlay.prototype.onAdd = function() { var div = document.createElement('div'); div.innerHTML = "I want the zoombar to go behind me."; div.style.backgroundColor = "white"; div.style.position = "relative"; div.style.fontSize = "20px"; // Add the element to the "overlayLayer" pane. var panes = this.getPanes(); panes.overlayLayer.appendChild(div); }; TestOverlay.prototype.draw = function() { }; // The onRemove() method will be called automatically from the API if // we ever set the overlay's map property to 'null'.

There is an overlay and thats about it, the rest comes from google maps api.

When drag event is fired, I get the coordinates of the dummy div, and put it in my overlay div. Thats about it :) .</p> |
32,980,329 | 0 | Avoiding cPickle in Ipython's parallel <p>I have some code that I have paralleled successfully in the sense that it gets an answer, but it is still kind of slow. Using cProfile.run(), I found that 121 seconds (57% of total time) were spent in cPickle.dumps despite a per call time of .003. I don't use this function anywhere else, so it must be occurring due to ipython's parallel.</p> <p>The way my code works is it does some serial stuff, then runs many simulations in parallel. Then some serial stuff, then a simulation in parallel. It has to repeat this many, many times. Each simulation requires a very large dictionary that I pull in from a module I wrote. I believe this is what is getting pickled many times and slowing the program down.</p> <p>Is there a way to push a large dictionary to the engines in such a way that it stays there permanently?

22,260,913 | 0 | Is a real-time system sdhedulable? <p>There is a question in my operating systems book about scheduling a system. </p> <p>The question is: A real-time system needs to handle two voice calls that each run every 5 msec and consumes 1 msec of CPU time per burst, plus one video at 25 frames/sec, with each frame requiring 20 msec of CPU time. Is the system schedulable?</p> <p>The solution manual has this answer: Each voice call runs 200 times/second and uses up 1 msec per burst, so each voice call needs 200 msec per second or 400 msec for the two of them. The video runs 25 times a second and uses up 20 msec each time, for a total of 500 msec per second. Together they consume 900</p> <p>The book does not explain how to come to this conclusion, or gives an algorithm.

So, for example, the features I'm trying to create might be the adjusted closes for the preceding 32 sessions.</p> <p>This is easy to do in a for-loop, but it takes quite a long time for large features sets (like going back to 1960 on "ge" and making each row contain the preceding 256 session values). Does anyone see a good way to vectorize this code?</p> <pre><code>import pandas as pd def featurize(equity_data, n_sessions, col_label='Adj Close'): """ Generate a raw (unnormalized) feature set from the input data. The value at col_label on the given date is taken as a feature, and each row contains values for n_sessions """ features = pd.DataFrame(index=equity_data.index[(n_sessions - 1):], columns=range((-n_sessions + 1), 1)) for i in range(len(features.index)): features.iloc[i, :] = equity_data[i:(n_sessions + i)][col_label].values return features </code></pre> <p>I could alternatively just multi-thread this easily, but I'm guessing that pandas does that automatically if I can vectorize it. I mention that mainly because my primary concern is performance. So, if multi-threading is likely to outperform vectorization in any significant way, then I'd prefer that.</p> <p>Short example of input and output:</p> <p><code>>>> eq_data Open High Low Close Volume Adj Close Date<br> 2014-01-02 15.42 15.45 15.28 15.44 31528500 14.96 2014-01-03 15.52 15.64 15.30 15.51 46122300 15.02 2014-01-06 15.72 15.76 15.52 15.58 42657600 15.09 2014-01-07 15.73 15.74 15.35 15.38 54476300 14.90 2014-01-08 15.60 15.71 15.51 15.54 48448300 15.05 2014-01-09 15.83 16.02 15.77 15.84 67836500 15.34 2014-01-10 16.01 16.11 15.94 16.07 44984000 15.57 2014-01-13 16.37 16.53 16.08 16.11 57566400 15.61 2014-01-14 16.31 16.43 16.17 16.40 44039200 15.89 2014-01-15 16.37 16.73 16.35 16.70 64118200 16.18 2014-01-16 16.67 16.76 16.56 16.73 38410800 16.21 2014-01-17 16.78 16.78 16.45 16.52 37152100 16.00 2014-01-21 16.64 16.68 16.36 16.41 35597200 15.90 2014-01-22 16.44 16.62 16.37 16.55 28741900 16.03 2014-01-23 16.49 16.53 16.31 16.43 37860800 15.92 2014-01-24 16.19 16.21 15.78 15.83 66023500 15.33 2014-01-27 15.90 15.91 15.52 15.71 51218700 15.22 2014-01-28 15.97 16.01 15.51 15.72 57677500 15.23 2014-01-29 15.48 15.53 15.20 15.26 52241500 14.90 2014-01-30 15.43 15.45 15.18 15.25 32654100 14.89 2014-01-31 15.09 15.10 14.90 14.96 64132600 14.61 >>> features = data.featurize(eq_data, 3) >>> features -2 -1 0 Date<br> 2014-01-06 14.96 15.02 15.09 2014-01-07 15.02 15.09 14.9 2014-01-08 15.09 14.9 15.05 2014-01-09 14.9 15.05 15.34 2014-01-10 15.05 15.34 15.57 2014-01-13 15.34 15.57 15.61 2014-01-14 15.57 15.61 15.89 2014-01-15 15.61 15.89 16.18 2014-01-16 15.89 16.18 16.21 2014-01-17 16.18 16.21 16 2014-01-21 16.21 16 15.9 2014-01-22 16 15.9 16.03 2014-01-23 15.9 16.03 15.92 2014-01-24 16.03 15.92 15.33 2014-01-27 15.92 15.33 15.22 2014-01-28 15.33 15.22 15.23 2014-01-29 15.22 15.23 14.9 2014-01-30 15.23 14.9 14.89 2014-01-31 14.9 14.89 14.61 </code></p> <p>So each row of features is a series of 3 (<code>n_sessions</code>) successive values from the 'Adj Close' column of the <code>features</code> DataFrame.</p> <p>====================</p> <p>Improved version based on Primer's answer below:</p> <p><code>def featurize(equity_data, n_sessions, column='Adj Close'): """ Generate a raw (unnormalized) feature set from the input data.

My joomla custom HTML module code is:</p> <pre><code><script type="text/javascript" src="js/jquery-1.6.2.min.js"></script> <script type="text/javascript" src="js/jquery-ui-1.8.16.custom.min.js"></script> <link type="text/css" href="css/overcast/jquery-ui-1.8.16.custom.css" rel="stylesheet" /> <form action="https://reservations.verticalbooking.com/reservation_hotel.htm" method="post" name="myform" id="myform" target="_blank" style="margin:0px; padding:0px;" onsubmit="invia_form();_gaq.push(['_linkByPost', this]);" > <!-- ###################### --> <!-- PARAMETERS TO CUSTOMIZE --> <input name="gg" id="gg" value="" type="hidden"> <input name="mm" id="mm" value="" type="hidden"> <input name="aa" id="aa" value="" type="hidden"> <input name="id_albergo" value="312" type="hidden"> <input name="lingua_int" value="ita" type="hidden"> <input name="dc" value="710" type="hidden"> <input name="id_stile" value="9456" type="hidden"> <input name="headvar" value="ok" type="hidden"> <input name="graph_be" value="4" type="hidden"> <div id="arrival_date" class="blocco"> <div class="label">Data di Arrivo</div> <div class="tendina"> <input id="datepicker" type="text" value="" > </div> </div> <div id="nights" class="blocco"> <div class="label">Notti</div> <div class="tendina"> <select class="select" name="notti_1" > <option value="1" selected>1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> <option value="6">6</option> <option value="7">7</option> <option value="8">8</option> <option value="9">9</option> <option value="10">10</option> <option value="11">11</option> <option value="12">12</option> <option value="13">13</option> <option value="14">14</option> <option value="15">15</option> <option value="16">16</option> </select> </div> </div> <div id="rooms" class="blocco"> <div class="label">Camere</div> <div class="tendina"> <select class="select" name="tot_camere"> <option value="1" selected>1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> <option value="6">6</option> <option value="7">7</option> <option value="8">8</option> <option value="9">9</option> <option value="10">10</option> </select> </div> </div> <div id="adults" class="blocco"> <div class="label">Adulti</div> <div class="tendina"> <select class="select" name="tot_adulti"> <option value="1">1</option> <option value="2" selected="selected">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> <option value="6">6</option> <option value="7">7</option> <option value="8">8</option> <option value="9">9</option> <option value="10">10</option> </select> </div> </div> <div id="children" class="blocco"> <div class="label">Bambini</div> <div class="tendina"> <select class="select" name="tot_bambini" > <option value="0" selected >0</option> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> <option value="6">6</option> <option value="7">7</option> <option value="8">8</option> <option value="9">9</option> <option value="10">10</option> </select> </div> </div> <div id="search" class="blocco"> <input id="button" type="submit" value="cerca" /> </input> </div> <div id="cancella"><a href="https://reservations.verticalbooking.com/reservation_hotel.htm?id_albergo=312&dc=710&lingua_int=ita&headvar=ok&id_stile=9456&graph_be=4&cancel=pren">Annulla/Modifica Prenotazione</a></div> </form> <script type="text/javascript"> $(document).ready( function() { var now = new Date(); var today = now.getDate() + '/' + (now.getMonth() + 1) + '/' + now.getFullYear(); $('#datepicker').val(today); }); </script> <script type="text/javascript"> $(function() { $( "#datepicker" ).datepicker({ minDate: "0", showOtherMonths: true, selectOtherMonths: true, altField: "#gg", altFormat: "dd" }); }); function invia_form() { var data = $( "#datepicker" ).attr('value'); //alert(data); data = data.split('/'); $('#gg').attr({value:data[0]}); $('#mm').attr({value:data[1]}); $('#aa').attr({value:data[2]}); //alert($('#gg').attr('value')+' - '+$('#mm').attr('value')+' - '+$('#aa').attr('value')); //$('#myform').submit(); } </script> </code></pre> <p>Although I read a few posts related on the forum, I really don't know where to start from... Any help would be highly appreciated... Thanks!</p> <p>Edit 1: The error is: </p> <pre><code>$(...).datepicker is not a function related code (line 435) is: $( "#datepicker" ).datepicker({ minDate: "0", showOtherMonths: true, selectOtherMonths: true, altField: "#gg", altFormat: "dd" }); </code></pre> |
10,372,132 | 0 | <p>You've said: <code>MainScreen2 *testJudith;</code> which sets testJudith to nil.</p> <p>You then created an array:</p> <pre><code>NSMutableArray *testJudithArray = [[NSMutableArray alloc]init]; </code></pre> <p>You then RESET testJudithArray to a mutable copy of testJudith's Judith array:</p> <pre><code>testJudithArray = [testJudith.Judith mutableCopy]; </code></pre> <p>But testJudith is nil. You haven't set it as anything. Which means the property of nil will always be/return nil. You then try to make a mutableCopy of nil. Thus, testJudithArray becomes nil.</p> <p>You have not created a testJudith to begin with, so you then never create the array you are asking to make a mutable copy of. The mutableCopy method thus returns nil (as any message sent to nil returns nil).</p> <p>Does this explain enough where your error is?</p> |
