  • Eliminating cyclic flows from a graph

    - by Jon Harrop
    I have a directed graph with flow volumes along edges and I would like to simplify it by removing all cyclic flows. This can be done by finding the minimum of the flow volumes along each edge in any given cycle and reducing the flows of every edge in the cycle by that minimum volume, deleting edges with zero flow. When all cyclic flows have been removed the graph will be acyclic. For example, if I have a graph with vertices A, B and C with flows of 1 from A?B, 2 from B?C and 3 from C?A then I can rewrite this with no flow from A?B, 1 from B?C and 2 from C?A. The number of edges in the graph has reduced from 3 to 2 and the resulting graph is acyclic. Which algorithm(s), if any, solve this problem?

  • Anyone Know a Great Sparse One Dimensional Array Library in Python?

    - by TheJacobTaylor
    I am working on an algorithm in Python that uses arrays heavily. The arrays are typically sparse and are read from and written to constantly. I am currently using relatively large native arrays and the performance is good but the memory usage is high (as expected). I would like to be able to have the array implementation not waste space for values that are not used and allow an index offset other than zero. As an example, if my numbers start at 1,000,000 I would like to be able to index my array starting at 1,000,000 and not be required to waste memory with a million unused values. Array reads and writes needs to be fast. Expanding into new territory can be a small delay but reads and writes should be O(1) if possible. Does anybody know of a library that can do it? Thanks!

  • django sort by manytomany relationship

    - by Marconi
    I have the following model: class Service(models.Model): ratings = models.ManyToManyField(User) Now if I wanna get all the service with ratings sorted in descending order I did something: services_list = Service.objects.filter(ratings__gt=0).distinct() services_list = list(services_list) services_list.sort(key=lambda service: service.ratings.all().count(), reverse=True) As you can see its a three step process and I don't feel right about this. Anybody who knows a better way to do this?

  • Effective Data Validation

    - by John Conde
    What's an effective way to handle data validation, say, from a form submission? Originally I had a bunch of if statements that checked each value and collected invalid values in an array for later retrieval (and listing). // Store errors here $errors = array(); // Hypothetical check if a string is alphanumeric if (!preg_match('/^[a-z\d]+$/i', $fieldvalue)) { $errors[$fieldname] = 'Please only use letters and numbers for your street address'; } // etc... What I did next was create a class that handles various data validation scenarios and store the results in an internal array. After data validation was complete I would check to see if any errors occurred and handle accordingly: class Validation { private $errorList = array(); public function isAlphaNumeric($string, $field, $msg = '') { if (!preg_match('/^[a-z\d]+$/i', $string)) { $this->errorList[$field] = $msg; } } // more methods here public function creditCard($cardNumber, $field, $msg = '') { // Validate credit card number } // more methods here public function hasErrors() { return count($this->errorList); } } /* Client code */ $validate = new Validation(); $validate->isAlphaNumeric($fieldvalue1, $fieldname1, 'Please only use letters and numbers for your street address'); $validate->creditCard($fieldvalue2, $fieldname2, 'Please enter a valid credit card number'); if ($validate->hasErrors()) { // Handle as appropriate } Naturally it didn't take long before this class became bloated with the virtually unlimited types of data to be validated. What I'm doing now is using decorators to separate the different types of data into their own classes and call them only when needed leaving generic validations (i.e. isAlphaNumeric()) in the base class: class Validation { private $errorList = array(); public function isAlphaNumeric($string, $field, $msg = '') { if (!preg_match('/^[a-z\d]+$/i', $string)) { $this->errorList[$field] = $msg; } } // more generic methods here public function setError($field, $msg = '') { $this->errorList[$field] = $msg; } public function hasErrors() { return count($this->errorList); } } class ValidationCreditCard { protected $validate; public function __construct(Validation $validate) { $this->validate = $validate; } public function creditCard($cardNumber, $field, $msg = '') { // Do validation // ... // if there is an error $this->validate->setError($field, $msg); } // more methods here } /* Client code */ $validate = new Validation(); $validate->isAlphaNumeric($fieldvalue, $fieldname, 'Please only use letters and numbers for your street address'); $validateCC = new ValidationCreditCard($validate); $validateCC->creditCard($fieldvalue2, $fieldname2, 'Please enter a valid credit card number'); if ($validate->hasErrors()) { // Handle as appropriate } Am I on the right track? Or did I just complicate data validation more then I needed to?

  • jQuery mobile ajax login form authentication

    - by Jakub Zak
    I know i already asked simillar question, but now when I work with jQuery Mobile I can't figure it out. So I have this form: <div data-role="page" data-theme="a" id="login_page"> <div data-role="header" data-position="fixed"> <h1>****</h1> </div> <div data-role="content"> <form id="login_form" method="POST" data-ajax="false"> <label for="basic">Username:</label> <input type="text" name="name" id="username" value=""/> <label for="basic">Password:</label> <input type="password" name="password" id="password" value=""/> <input type="submit" value="Login" id="login" name="login"/> </form> </div> <div data-role="footer" data-position="fixed"> <div data-role="navbar"></div> </div> </div> And I need to submit Username and Password to php script, where php replies and send "success" or "failed". Here is php: <?php session_start(); $username = $_POST["name"]; $password = $_POST["password"]; include('mysql_connection.php'); mysql_select_db("jzperson_imesUsers", $con); $res1 = mysql_query("SELECT * FROM temp_login WHERE username='$username' AND password='$password'"); $count=mysql_num_rows($res1); if($count==1){ echo "success"; }else{ echo "failed"; } ?> And to do all this I want to use this script: $(document).ready(function() { $("form").submit(function(){ $.mobile.showPageLoadingMsg(); $.ajax({ url: "http://imes.jzpersonal.com/login_control.php", type: "POST", dataType: "jsonp", jsonp: "jsoncallback", data: $("form#login_form").serialize(), success: function( response ){ $.mobile.changePage( "http://imes.jzpersonal.com/user_panel.html"); } }); return false; }); }); But I can't make it work, I know I must have mistakes in there, I just can't find them, or better way to do it. Thank you in advance for any help.

  • How to get min/max of two integers in Postgres/SQL?

    - by HRJ
    How do I find the maximum (or minimum) of two integers in Postgres/SQL? One of the integers is not a column value. I will give an example scenario: I would like to subtract an integer from a column (in all rows), but the result should not be less than zero. So, to begin with, I have: UPDATE my_table SET my_column = my_column - 10; But this can make some of the values negative. What I would like (in pseudo code) is: UPDATE my_table SET my_column = MAXIMUM(my_column - 10, 0);

  • When using the Facebook Connect Actionscript API (no JS, just straight Flash), how can I listen for

    - by techno
    Hey guys, When using the Facebook Connect AS API, the user will be prompted to log in to FB in a pop up window. At this point I want to block interaction in my flash movie and wait for them to complete logging in (or potentially close/cancel and not log in). I have seen examples where people put up a Flex "Alert" box with some hint like "Press ok once you have logged into facebook", but I want to automatically listen for them logging in or canceling/closing the popup window without logging in. Is there an event I can listen for with flash? So far I am using ZERO javascript, but I guess I could add a little if it is needed for this... I definitely want to avoid having some sort of "Press OK" alert box, but instead have the flash application automatically react to the user logging in with the popup window.

  • Getting fields of a class through reflection

It is an embarrassingly simple and stupid piece of code that I am writing in a test solution before I do something really useful in production code. Strangely, the GetFieldsOf method reports a zero length array on the "Amazing" class. Help. class Amazing { private NameValueCollection _nvc; protected NameValueCollection _myDict; } private static FieldInfo[] GetFieldsOf(string className, string nameSpace = "SomeReflection") { Type t; return (t = Assembly.GetExecutingAssembly().GetType( string.Format("{0}.{1}", nameSpace, className) )) == null ? null : t.GetFields(); }

  • Issues accessing an object's array values - returns null or 0s

    - by PhatNinja
    The function below should return an array of objects with this structure: TopicFrequency = { name: "Chemistry", //This is dependent on topic data: [1,2,3,4,5,6,7,8,9,10,11,12] //This would be real data }; so when I do this: myData = this.getChartData("line"); it should return two objects: {name : "Chemistry", data : [1,2,3,4,51,12,0,0, 2,1,41, 31]} {name : "Math", data : [0,0,41,4,51,12,0,0, 2,1,41, 90]} so when I do console.log(myData); it's perfect, returns exactly this. However when I do console.log(myData[0].data) it returns all 0s, not the values. I'm not sure what this issues is known as, and my question is simple what is this problem known as? Here is the full function. Somethings were hardcoded and other variables (notable server and queryContent) removed. Those parts worked fine, it is only when manipulated/retreiving the returned array's values that I run into problems. Note this is async. so not sure if that is also part of the problem. getChartData: function (chartType) { var TopicsFrequencyArray = new Array(); timePairs = this.newIntervalSet("Month"); topicList = new Array("Chemistry", "Math");//Hard coded for now var queryCopy = { //sensitive information }; for (i = 0; i < topicList.length; i++) { var TopicFrequency = { name: null, data: this.newFilledArray(12, 0) }; j = 0; TopicFrequency.name = topicList[i]; while (j < timePairs.length) { queryCopy.filter = TopicFrequency.name; //additional queryCopy parameter changes made here var request = esri.request({ url: server, content: queryCopy, handleAs: "json", load: sucess, error: fail }); j = j + 1; function sucess(response, io) { var topicCountData = 0; query = esri.urlToObject(io.url); var dateString = query.query.fromDate.replace("%", " "); dateString = dateString.replace(/-/g, "/"); dateString = dateString.split("."); date = new Date(dateString[0]); dojo.forEach(response.features, function (feature) { if (feature.properties.count > 0) { topicCountData = feature.properties.count; } TopicFrequency.data[date.getMonth()] = topicCountData; }); } function fail(error) { j = j + 1; alert("There was an unspecified error with this request"); console.log(error); } } TopicsFrequencyArray.push(TopicFrequency); } },

  • Ambiguous Evaluation of Lambda Expression on Array

    - by Joe
    I would like to use a lambda that adds one to x if x is equal to zero. I have tried the following expressions: t = map(lambda x: x+1 if x==0 else x, numpy.array) t = map(lambda x: x==0 and x+1 or x, numpy.array) t = numpy.apply_along_axis(lambda x: x+1 if x==0 else x, 0, numpy.array) Each of these expressions returns the following error: ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all() My understanding of map() and numpy.apply_along_axis() was that it would take some function and apply it to each value of an array. From the error it seems that the the lambda is being evaluated as x=array, not some value in array. What am I doing wrong? I know that I could write a function to accomplish this but I want to become more familiar with the functional programming aspects of python.

  • SQL Azure server as unit of billing

    - by vtortola
    Hi, One of the azure training kit presentation says: Each account has zero or more logical servers Provisioned via a common portal Establishes a billing instrument Each logical server has one or more databases Contains metadata about database & usage Unit of authentication, geo-location, billing, reporting Generated DNS-based name Each database has standard SQL objects Users, Tables, Views, Indices, etc Unit of consistency So now I'm lost :D. Were not the databases themselves the units of billing? I mean, I thought that servers were just like logical containers and you were charged per number and size of databases. How servers are billed? Thanks.

  • How to make javascript for font sizes fully language dependent?

    - by toonoid
    Hello All I have a multilanguage webiste English and Arabic. The javascript for the fontsizes is included in the theme not in the .css. Both language have different fontsize 16 and 12. When switching from English to Arabic the English letters such as ( dates and stuff like that ) are shown way too big. And when switching from English to Arabic the arabic letters are too small. I would really like to make this javascrip fully language dependent so that the English letters being shown in the Arabic version keeps the same fontsize as in English version and vice versa for arabic. //-- function setstyle(tag){ var elements = document.getElementsByTagName(tag); for (var i = 0; i The following script is the current javascript included in the theme. I would really appreciate it if somebody out there could help me with this problem. My knowledge of javascript is to be honest zero. Thanks TOONOID
