  • Where can I find a powerful, standards compliant, web-based interactive org chart API?

    - by Adam Soltys
    Hi, I'm looking to build an interactive web-based org chart for a large organization. I somewhat like the interface at ancestry.com where you can hover over people and pan/zoom around and click on different nodes to make them the root. Ideally, I'd like it if people could belong to multiple organizational entities like committees, working groups, etc. In other words the API should support graphs in general, not just trees. I'd like to be able to visually explode each organizational substructure into substituents by clicking on it, with a nice animation of the employees ballooning or spilling out so you can really interactively drill down through the organization. I found http://code.google.com/apis/visualization/documentation/gallery/orgchart.html but it looks a bit rudimentary. I know there are desktop tools like OrgPlus and Visio that can build static charts but I'm really looking for a free, web-based API with open standards-based output like SVG or HTML5 Canvas elements rather than Flash or some proprietary output. Something I can embed into a custom web application and style myself. Something interactive.

  • Indexing table with duplicates MySQL/MSSQL with millions of records

    - by Tesnep
    I need help in indexing in MySQL. I have a table in MySQL with following rows: ID Store_ID Feature_ID Order_ID Viewed_Date Deal_ID IsTrial The ID is auto generated. Store_ID goes from 1 - 8. Feature_ID from 1 - let's say 100. Viewed Date is Date and time on which the data is inserted. IsTrial is either 0 or 1. You can ignore Order_ID and Deal_ID from this discussion. There are millions of data in the table and we have a reporting backend that needs to view the number of views in a certain period or overall where trial is 0 for a particular store id and for a particular feature. The query takes the form of: select count(viewed_date) from theTable where viewed_date between '2009-12-01' and '2010-12-31' and store_id = '2' and feature_id = '12' and Istrial = 0 In MSSQL you can have a filtered index to use for Istrial. Is there anything similar to this in MySQL? Also, Store_ID and Feature_ID have a lot of duplicate data. I created an index using Store_ID and Feature_ID. Although this seems to have decreased the search period, I need better improvement than this. Right now I have more than 4 million rows. To search for a particular query like the one above, it looks at 3.5 million rows in order to give me the count of 500k rows. PS. I forgot to add view_date filter in the query. Now I have done this.

  • Error: '$viewMap[...]' is null or not an object

    - by DK
    My jQuery/Javascript knowledge is limited I'm afraid. I have a "how did you hear about us" dropdown on a form. However, I get the following Javascript error on change: Error: '$viewMap[...]' is null or not an object My dropdown looks like this: <select onchange="setSourceID(this.value)" name="sourceID" id="sourceID" class="required"> <option value="" selected="selected">Please choose&#8230;</option> <option value="National Paper">National Paper</option> <option value="Magazine">Magazine</option> <option value="Regional Paper">Regional Paper</option> <option value="9682">Internet Search</option> <option value="9684">Recommendation</option> <option value="9683">Other</option> </select> <!-- some additional dropdowns below that appear based on what's selected above --> <select onchange="setSourceID(this.value)" name="referrerName[]" id="referrer1" class="smartField"> <option value="" selected="selected">Please choose&#8230;</option> <option value="The Times">The Times</option> etc... </select> and so on... My Javascript looks like this: $(document).ready(function() { $('.smartField').hide(); $.viewMap = { '' : $([]), 'National Paper' : $('#referrer1'), 'Magazine' : $('#referrer2'), 'Regional Paper' : $('#referrer3') //'Internet Search' : $('#referrer4'), //'Recommendation' : $('#referrer5'), //'Other' : $('#referrer6') }; $("#sourceID").bind(($.browser.msie ? "click" : "change"), function () { $.each($.viewMap, function() { this.hide(); }); // hide all $.viewMap[$(this).val()].show(); // show current }); }); Does anybody have any idea where I'm going wrong? Any help very much appreciated.

  • MySQL Replication fix after server shutdown/start

    - by Jagbir
    Server1 is Master Server2 is Slave Both are in our AWS testing env and we stop them once done with our work. When start again, Master rotates/creates new binary log file but slave keep looking for same/existing one and replication stops. Right now, I'm manually repairing it by (slave): stop slave; CHANGE MASTER TO MASTER_HOST='xx', MASTER_USER='xxx', MASTER_PASSWORD='xxx' , MASTER_LOG_FILE='new-mysql-bin.00000x',MASTER_LOG_POS=107; start slave; show slave status\G and slave becomes good again.Mysql is 5.5.x on Ubuntu 12.04. Will appreciate any help in automating it.

  • Loading specific files from arbitrary directories?

    - by Haydn V. Harach
    I want to load foo.txt. foo.txt might exist in the data/bar/ directory, or it might exist in the data/New Folder/ directory. There might be a different foo.txt in both of these directories, in which case I would want to either load one and ignore the other according to some order that I've sorted the directories by (perhaps manually, perhaps by date of creation), or else load them both and combine the results somehow. The latter (combining the results of both/all foo.txt files) is circumstantial and beyond the scope of this question, but something I want to be able to do in the future. I'm using SDL and boost::filesystem. I want to keep my list of dependencies as small as possible, and as cross-platform as possible. I'm guessing that my best bet would be to get a list of every directory (within the data/ folder), sort/filter this list, then when I go to load foo.txt, I search for it in each potential directory? This sounds like it would be very inefficient, if I have dozens of potential directories to search through every time. What's the best way to go about accomplishing this? Bonus: What if I want some of the directories to be archives? ie. considering both data/foo/ and data/bar.zip to both be valid, and pull foobar.txt from either one without caring.

  • Test for `point` within an attachment in `mail-mode`

    - by lawlist
    I'm looking for a better test to determine when point is within a hidden attachment in mail-mode (which is used by wl-draft-mode). The attachments are mostly hidden and look like this: --[[application/xls Content-Disposition: attachment; filename="hello-world.xls"][base64]] The test of invisible-p yields a result of nil. I am current using the following test, but it seems rather poor: (save-excursion (goto-char (point-max)) (goto-char (previous-char-property-change (point))) (goto-char (previous-char-property-change (point))) (re-search-backward "]]" (point-at-bol) t))) Any suggestions would be greatly appreciated. Here is the full snippet: (goto-char (point-max)) (cond ((= (save-excursion (abs (skip-chars-backward "\n\t"))) 0) (insert "\n\n")) ((and (= (save-excursion (abs (skip-chars-backward "\n\t"))) 1) (not (save-excursion (goto-char (previous-char-property-change (point))) (goto-char (previous-char-property-change (point))) (re-search-backward "]]" (point-at-bol) t)))) (insert "\n"))) GOAL:  If there are no attachments and no new lines at the end of the buffer, then insert \n\n and then insert the attachment thereafter. If there is just one new line at the end of the buffer, then insert \n and then insert the attachment thereafter. If there is an attachment at the end of the buffer, then do not insert any new lines.

  • Computer Science taxonomy

    - by Bakhtiyor
    I am developing web application where users have collection of tags. I need to create a suggestion list for users based on the similarity of their tags. For example, when a user logs in to the system, system gets his tags and search these tags in the DB of users and showing users who have similar tags. For instance if User 1 has following tags [Linux, Apache, MySQL, PHP] and User 2 has [Windows, IIS, PHP, MySQL] it says that User 2 matchs User 1 with a weight of 50%, because he has 2 similar tags(PHP and MySQL). But imagine the situation where User 1 has [ASP, IIS, MS Access] and User 2 has [PHP, Apache, MySQL]. In this situation my system doesn't suggest User 2 as a "friend" to User 1 or vice versa. But we now that these two users has similarity on the the field of work, both works on Web Technology (or Web Programming, etc). So, that is why I need kind of taxonomy of computer science (right now, but probably I would need taxonomy of other fields also, like medicine, physics, mathematics, etc.) where these concepts are categorized and so that when I search for similarity of ASP and PHP, for example, it can say that they have similarity and belong into one group(or category). I hope I described my problem clearly, but if something wrong explained would be happy for your corrections. Thanks

  • What happens when modifying Gemfile.lock directly?

    - by Mik378
    Since the second time of bundle install execution, dependencies are loaded from Gemfile.lock when Gemfile isn't changed. But I wonder how detection of changes is made between those two files. For instance, if I'm adding a new dependency directly into Gemfile.lock without adding it into Gemfile (as opposed to the best practice since Gemfile.lock is auto-generated from Gemfile), would a bundle install consider Gemfile as changed ? Indeed, does bundle install process compares the whole Gemfile and Gemfile.lock trees in order to detect changes? If it is, even if I'm adding a dependency directly to Gemfile.lock, Gemfile would be detected as changed (since different) and would re-erase Gemfile.lock (so losing the added dependency...) What is the process of bundle install since the launch for the second time ? To be more clear, my question is: Are changes based only from Gemfile ? That means bundler would keep a Gemfile snapshot of every bundle install execution number N and merely compares it to the bundle install execution N+1 ? Or none snapshot are created in bundler memory and bundler makes a comparison with Gemfile.lock each time to detect if Gemfile must be considered as changed.

  • Fundamentals of Deserialization in .NET?

    - by Codehelp
    I have been working with XML for past couple of months with .NET Basically all the work I do involve XML in oneway of another so I thought it would be good to learn the serialization and deserialization part of the game. My work mostly involves the 'Deserialization' part of it. Almost every time I have an XML file which has to be used by the application that I write. An object form of the XML is the best way to use. Now initially the XML was very straight forward, just a couple of tags which would translate into a class very easily using XSD.exe tool. Things grew a bit complex with nesting of tags and I found Xsd2Code gen tool work fine. During this whole process I have been able to do my work with a lot of help from Stackoverflow community, thanks for that, but I think I have missed the forest for the trees. I need to know how Deserialization works in .NET Fundamentally, I would like to know what happens behind the scenes in taking a XML and converting it into a usable object. Code samples have helped me in the past, and as mentioned earlier the problem get's solved but the learning does not happen. So, if anyone can guide to resources that can get me started on the Deserialization part of the game, I would be thankful to them. Regards.

  • Speed/expensive of SQLite query vs. List.contains() for "in-set" icon on list rows

    - by kpdvx
    An application I'm developing requires that the app main a local list of things, let's say books, in a local "library." Users can access their local library of books and search for books using a remote web service. The app will be aware of other users of the app through this web service, and users can browse other users' lists of books in their library. Each book is identified by a unique bookId (represented as an int). When viewing books returned through a search result or when viewing another user's book library, the individual list row cells need to visually represent if the book is in the user's local library or not. A user can have at most 5,000 books in the library, stored in SQLite on the device (and synchronized with the remote web service). My question is, to determine if the book shown in the list row is in the user's library, would it be better to directly ask SQLite (via SELECT COUNT(*)...) or to maintain, in-memory, a List or int[] array of some sort containing the unique bookIds. So, on each row display do I query SQLite or check if the List or int[] array contains the unique bookId? Because the user can have at most 5,000 books, each bookId occupies 4 bytes so at most this would use ~ 20kB. In thinking about this, and in typing this out, it seems obvious to me that it would be far better for performance if I maintained a list or int[] array of in-library bookIds vs. querying SQLite (the only caveat to maintaining an int[] array is that if books are added or removed I'll need to grow or shrink the array by hand, so with this option I'll most likely use an ArrayList or Vector, though I'm not sure of the additional memory overhead of using Integer objects as opposed to primitives). Opinions, thoughts, suggestions?

  • Is there a word processor similar to MS Word which saves files as readable txt files?

    - by zenbomb
    I'm writing a paper together with my supervisor and would like to have a more sophisticated version control than *_291112_NEW_NEW_revised1.doc files. My supervisor is a non-computer person will never ever use LaTeX or git and loves MS Word. I'm therefore looking for an alternative to Word (I need commenting on text passages!) which stores the files as clean text (Markup for formating is fine), so I'm able to put them under version control on my side. I'm aware that git can also handle binary files, but I'd prefer the cleaner way of looking at the contents directly. If there's a way to automatically extract the text from word files, I'm fine with that too for now.

  • lists searches in SYB or uniplate haskell

    - by Chris
    I have been using uniplate and SYB and I am trying to transform a list For instance type Tree = [DataA] data DataA = DataA1 [DataB] | DataA2 String | DataA3 String [DataA] deriving Show data DataB = DataB1 [DataA] | DataB2 String | DataB3 String [DataB] deriving Show For instance, I would like to traverse my tree and append a value to all [DataB] So my first thought was to do this: changeDataB:: Tree -> Tree changeDataB = everywhere(mkT changeDataB') chanegDataB'::[DataB] -> [DataB] changeDataB' <add changes here> or if I was using uniplate changeDataB:: Tree -> Tree changeDataB = transformBi changeDataB' chanegDataB'::[DataB] -> [DataB] changeDataB' <add changes here> The problem is that I only want to search on the full list. Doing either of these searches will cause a search on the full list and all of the sub-lists (including the empty list) The other problem is that a value in [DataB] may generate a [DataB], so I don't know if this is the same kind of solution as not searching chars in a string. I could pattern match on DataA1 and DataB3, but in my real application there are a bunch of [DataB]. Pattern matching on the parents would be extensive. The other thought that I had was to create a data DataBs = [DataB] and use that to transform on. That seems kind of lame, there must be a better solution.

  • Concept: Information Into Memory Location.

    - by Richeve S. Bebedor
    I am having troubles conceptualizing an algorithm to be used to transform any information or data into a specific appropriate and reasonable memory location in any data structure that I will be devising. To give you an idea, I have a JPanel object instance and I created another Container type object instance of any subtype (note this is in Java because I love this language), then I collected those instances into a data structure not specifically just for those instances but also applicable to any type of object. Now my procedure for fetching those data again is to extract the object specific features similar in category to all object in that data structure and transform it into a integer data memory location (specifically as much as possible) or any type of data that will pertain to this transformation. And I can already access that memory location without further sorting or applications of O(n) time complex algorithms (which I think preferable but I wanted to do my own way XD). The data structure is of any type either binary tree, linked list, arrays or sets (and the like XD). What is important is I don't need to have successive comparing and analysis of data just to locate information in big structures. To give you a technical idea, I have to an array DS that contains JLabel object instance with a specific name "HelloWorld". But array DS contains other types of object (in multitude). Now this JLabel object has a location in the array at index [124324] (which is if you do any type of searching algorithm just to arrive at that location is conceivably slow because added to it the data structure used was an array *note please disregard the efficiency of the data structure to be used I just want to explain to you my concept XD). Now I want to equate "HelloWorld" to 124324 by using a conceptually made function applicable to all data types. So that I can do a direct search by doing this DS[extractLocation("HelloWorld")] just to get that JLabel instance. I know this may sound crazy but I want to test my concept of non-sorting feature extracting search algorithm for any data structure wherein my main problem is how to transform information to be stored into memory location of where it was stored.

  • Clear button at uisearchbar not working at all

    - by kevin.ng
    I created a search bar programmatically and added to my view using the codes below: - (void)viewDidLoad { searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(xPositionForSearchBar, yPositionForSearchBar, widthForSearchBar, heightForSearchBar)]; UIView *bg = [[searchBar subviews] objectAtIndex:0]; searchBar.delegate = self; searchBar.placeholder = @"Search record"; for(UIView *view in searchBar.subviews){ if([view isKindOfClass:[UITextField class]]){ UITextField *tf = (UITextField *)view; tf.delegate = self; break; } } [bg removeFromSuperview]; [self.view addSubview: searchBar]; } The code is implemented with UISearchBarDelegate and UITextFieldDelegate. I have tried using - (void)searchBarCancelButtonClicked:(UISearchBar *)aSearchBar { NSLog(@"cancel clicked"); searchBar.text = @""; [aSearchBar resignFirstResponder]; } - (BOOL)textFieldShouldClear:(UITextField *)textField { NSLog(@"clear"); [self performSelector:@selector(searchBarCancelButtonClicked:) withObject:searchBar afterDelay: 0.1]; return YES; } and yet, the text inside the searchBar is not cleared at all when i click on the "clear button" - a circle with a "X" inside. The clear button works when I implemented it in IB. Wonder why? Kindly advice, many thanks.

  • Javascript Regex: Testing string for intelligent query

    - by Shyam
    Hi, I have a string that holds user input. This string can contain various types of data, like: a six digit id a zipcode that contains out of 4 digits and two alphanumeric characters a name (characters only) As I am using this string to search through a database, the query type is determined on the type of search, which i want to handle serverside using JavaScript (yes, I am using JavaScript serverside). Searching on StackOverflow, brought me some interesting information, like the .test-method, which seems perfect for my needs. The test-method returns either true or false based on the evaluation on the string using a regex object. I am using this page as a reference: http://www.javascriptkit.com/jsref/regexp.shtml So I am trying to determine the zipcode, by using the following very noobish regex. var r = /[A-Za-z]{2,2}/ As far I can understand, this should limit the amount of occurrences of alphanumeric characters to a maximum of two. See beneath the output of my JavaScript console. > var r = /[A-Za-z]{2,2}/ > var x = "2233AL" > r.test(x) true > var x = "2233A" > r.test(x) false > var x = "2233ALL" > r.test(x) true /* i want this to be false */ > A little help would be really appreciated!

  • How to make checkboxes have the same submit behavior as other inputs?

    - by Tim Santeford
    I have a search form where several checkboxes are checked by default. When the form submits, as a GET, the url will only contain the list of checkboxes that were left checked. http://www.example.com/page/?checkbox1=yes&checkbox2=yes It is difficult with this scenario to determine the difference between when a user first arrives at this search page and when they submit the form with all checkboxes unchecked because the querystrings look the same. To combat this problem I have started injecting a hidden field before the checkbox with the same name and a 'no' value. When the checkbox is unchecked the browser will send the hidden field's no value and when the checkbox is set then the browser is overriding the hidden field with the checkbox's 'yes' value. <input type="hidden" name="checkbox1" value="no" /> <input type="checkbox" name="checkbox1" value="yes" /> when the user submits the form with all checkboxes unchecked I get this querystring: http://www.example.com/page/?checkbox1=no&checkbox2=no This seems to work on ff, chrome, ie5.5+ so I'am I safe in using this method or is there a better way to make checkboxes submit like inputs and selects?

  • jQuery select by two name roots and perform one of two function depending on which root was selected

    - by RetroCoder
    I'm trying to get this code to work in jQuery and I'm trying to make sure that for each iteration of each root element, its alternate root element for that same iteration doesn't contain anything. Otherwise it sets the .val("") property to an empty string. Looking for a simple solution if possible using search, find, or swap. Each matching number is on the same row level and the same iteration count. I have two input types of input text elements with two different root names like so: 1st Root is "rootA" <input type="text" name="rootA1" /> <input type="text" name="rootA2 /> <input type="text" name="rootA3" /> 2nd Root is "rootB" <input type="text" name="rootB1" /> <input type="text" name="rootB2 /> <input type="text" name="rootB3" /> On blur if any of rootA is called call function fnRootA();. On blur if any of rootB is called call function fnRootB();. Again, I'm trying to make sure that for each iteration like 1 that the alternate root doesn't contain anything, else it sets the .val("") property to an empty string of the root being blurred. My current code works for a single element but wanted to use find or search but not sure how to construct it.. $("input[name='rootA1']").blur(function(e) { fnRootA(1); // this code just removes rootA1's value val("") //if rootB1 has something in it value property // the (1) in parenthesis is the iteration number });

  • Getting Values from fetched Core Data

    - by user571905
    Hi there, Thanks to the wonderful people on this forum, I have overcome most of my Core Data woes. However one persists, and I'm certain it is a simple fix. I have a recipe app that parses an XML doc on load and puts the data in Core Data. Then I search that Core Data for particular recipes, ingredients, etc. Everything is working with one exception... I cannot do anything with the data I retrieve. For example, I search the core data for "eggplant" and get this at the end of the process: "<RecipeData: 0x6112a40> (entity: RecipeData; id: 0x6113880 <x-coredata:///RecipeData/tCDE9A0EE-DA3F-4BD0-AEF8-3C038586991D4> ; data: {\n ingredients = \"Eggplant|Cheese|Tomatoes|\";\n name = \"Eggplant Parm\";\n time = 40;\n})" How do I get the info out of there? I tried looping through, but that causes the app to crash: for (NSString* key in selectedRecipe) { id value = [selectedRecipe objectForKey:key]; NSLog(@"IN LOOP: %@", value); } Any suggestions? Thank you for your time.

  • case insenstive string replace that correctly works with ligatures like "ß" <=> "ss"

    - by usr
    I have build a litte asp.net form that searches for something and displays the results. I want to highlight the search string within the search results. Example: Query: "p" Results: a<b>p</b>ple, banana, <b>p</b>lum The code that I have goes like this: public static string HighlightSubstring(string text, string substring) { var index = text.IndexOf(substring, StringComparison.CurrentCultureIgnoreCase); if(index == -1) return HttpUtility.HtmlEncode(text); string p0, p1, p2; text.SplitAt(index, index + substring.Length, out p0, out p1, out p2); return HttpUtility.HtmlEncode(p0) + "<b>" + HttpUtility.HtmlEncode(p1) + "</b>" + HttpUtility.HtmlEncode(p2); } I mostly works but try it for example with HighlightSubstring("ß", "ss"). This crashes because in Germany "ß" and "ss" are considered to be equal by the IndexOf method, but they have different length! Now that would be ok if there was a way to find out how long the match in "text" is. Remember that this length can be != substring.Length. So how do I find out the length of the match that IndexOf produces in the presence of ligatures and exotic language characters (ligatures in this case)?

Just for reference, here's the structure of the files: <haarcascade_frontalface_alt type_id="opencv-haar-classifier"> <size>20 20</size> <stages> <_> <!-- stage 0 --> <trees> <_> <!-- tree 0 --> <_> <!-- root node --> <feature> <rects> <_>3 7 14 4 -1.</_> <_>3 9 14 2 2.</_></rects> <tilted>0</tilted></feature> <threshold>4.0141958743333817e-003</threshold> <left_val>0.0337941907346249</left_val> <right_val>0.8378106951713562</right_val></_></_> <_>
