  • intersection of three sets in python?

    - by Phil Brown
    Currently I am stuck trying to find the intersection of three sets. Now these sets are really lists that I am converting into sets, and then trying to find the intersection of. Here's what I have so far: for list1 in masterlist: list1=thingList1 for list2 in masterlist: list2=thingList2 for list3 in masterlist: list3=thingList3 d3=[set(thingList1), set(thingList2), set(thingList3)] setmatches c= set.intersection(*map(set,d3)) print setmatches and I'm getting set([]) Script terminated. I know there's a much simpler and better way to do this, but I can't find one...

  • PHP mail may be filtered out by spam?

    - by Derek
    I am creating a small company, and would like to send out emails to my clients once they have signed up for my service to activate their accounts. I am currently using PHP's mail() function, however I am worried that my emails are being filtered out by spam filters. Is there a better way to go about this? $email = 'XZY Client Email address @ somedomain.com'; $emailSubject = "Welcome to XYZ Service!"; $to = $email; $subject .= "".$emailSubject.""; $headers .= "From: [email protected]\r\n" . "X-Mailer: php"; $headers .= "MIME-Version: 1.0\r\n"; $headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n"; $message = "<html><body>"; $message .= "Welcome to XYZ Service! \n Activate your account by clicking the following link: link..."; mail($to, $subject, $message, $headers); Is there a way to authenticate these emails so that my clients know that they are from my actual service? Thank you in advance!

  • EF Stored Procedure Complex Type

    - by Web Dev
    I am using EF4. I am somewhat confused on on the Entity Framework Complex name. When I go to Functional Import of a Stored Procedure name and it ask me to type in the Complex name, is that supposed to be the name of of a class that can handle that output. For examle, say if my stored procedure returns FirstName, LastName. Is the Complex name supposed to be a class that can handle that output in this case PersonName? public class PersonName { public string FirstName {get; set;} public string LastName {get;set} }

  • Agile web development with Rails 4 interface difficulties

    - by Luke Annison
    I've been following along with the examples in the book in making a online catalog and am having a couple of discouraging difficulties in Chapter 8 task C: Catalog display. I have input the code for the stylesheets as instructed but it has created a slightly skewed result as compared to what is shown in the book. Whilst minor and aesthetic in nature its a little shock to my confidence and slightly irritating when trying to carry on through the book. I have too little rep to post a pic, but heres the link: http://s11.postimage.org/3pwlzfiwj/Screen_Shot_2012_10_08_at_22_29_56.png) As you can see the boarder seems a little confused and the image at the top is covering the header text. I've been through the code time and time again but can't seem find out where I've gone wrong. Could anybody give me some clues?

  • jquery datepicker - retrieve events and show on hover in dialog - allow the a href to be clicked to access individual event entries

    - by paul724
    Please see this jsfiddle - http://jsfiddle.net/paul724/HXb6v/ What is working: The datepicker displays correctly, picks up the css for todays date and on hover. The dialog box follows the mouse On click the dialog box "stops" and displays a link What I want to achieve When a table cell is hovered over the title of the dialog box shows the date e.g "Mon 8th Oct 2012" When a table cell is hovered over the html of the dialog box shows the events for that day in list format (there is code that succesfully retrieves the first row in function getSelectedDates() ) function getSelectedDates() needs to be called in the hover event - showing multiple events for that date in the dialog box I hope that if we can display the date being hovered over in the title of the dialog then we can use the same information to retrieve the rows from the database to populate the html of the dialog for that day

  • trying to find if a file exists in a given path

    - by Yeshwanth Venkatesh
    I am fairly new to java and I am trying to find if the file specified in the LINUX path exists. private void validateFilePath(String filePath) { File dir = new File(filePath); if(dir.exists()){ System.out.println("File exists in the path " + dir); setTARGET_IMG_DIR("filePath"); return; }else{ System.out.println("File does not exists in the path: " + dir); return; } } The dir.exists works fine if I give a absolute path from my root like this /Users/yv/Documents/Eclipse-workspace/InputParser/bin/test.txt but if I give a relative path like test.txt or /InputParser/bin/test.txt it says files does not exists. I am planing on creating a jar of this projects and hence this should work with both relative path(files in the same directory) and absolute path from the root. How can I handle this ? Is it possible to search for the absolute path of that file from the root and append it to the file name ?

  • specifying multiple URLs with cURL/PHP using square brackets

    - by Raj Gundu
    I have a large array of URLS similar to this: $nodes = array( 'http://www.example.com/product.php?page=1&sortOn=sellprice', 'http://www.example.com/product.php?page=2&sortOn=sellprice', 'http://www.example.com/product.php?page=3&sortOn=sellprice' ); The cURL manual states here (http://curl.haxx.se/docs/manpage.html) that i can use square brackets '[]' to specify multiple urls. Used in the above example this would be similar to this: 'http://www.example.com/product.php?page=[1-3]&sortOn=sellprice' So far i have been unable to reference this correctly. This is the complete code segment I'm currently trying to utilize this with: $nodes = array( 'http://www.example.com/product.php?page=1&sortOn=sellprice', 'http://www.example.com/product.php?page=2&sortOn=sellprice', 'http://www.example.com/product.php?page=3&sortOn=sellprice' ); $node_count = count($nodes); $curl_arr = array(); $master = curl_multi_init(); for($i = 0; $i < $node_count; $i++) { $url =$nodes[$i]; $curl_arr[$i] = curl_init($url); curl_setopt($curl_arr[$i], CURLOPT_RETURNTRANSFER, true); curl_multi_add_handle($master, $curl_arr[$i]); } do { curl_multi_exec($master,$running); } while($running > 0); echo "results: "; for($i = 0; $i < $node_count; $i++) { $results = curl_multi_getcontent ( $curl_arr[$i] ); echo( $i . "\n" . $results . "\n"); echo 'done'; I can't seem to find any more documentation on this. Thanks in advance.

  • Synchronize write to two collections

    - by glaz666
    I need to put some value to maps if it is not there yet. The key-value (if set) should always be in two collections (that is put should happen in two maps atomically). I have tried to implement this as follows: private final ConcurrentMap<String, Object> map1 = new ConcurrentHashMap<String, Object>(); private final ConcurrentMap<String, Object> map2 = new ConcurrentHashMap<String, Object>(); public Object putIfAbsent(String key) { Object retval = map1.get(key); if (retval == null) { synchronized (map1) { retval = map1.get(key); if (retval == null) { Object value = new Object(); //or get it somewhere synchronized (map2) { map1.put(key, value); map2.put(key, new Object()); } retval = value; } } } return retval; } public void doSomething(String key) { Object obj1 = map1.get(key); Object obj2 = map2.get(key); //do smth } Will that work fine in all cases? Thanks

  • Adjust width of td to make make row widths even

    - by user1729886
    I am trying to produce a table with a different number of cells in each row. The first row is a header row (every other row contains cells). This header is the width of the table. The second row has 2 cells in it... the third has 1 cell... the fourth has 4 cells... the fifth and final row has 3 cells. I want the table set up so that the rows span the full width of the table. If the table is 1000px... The header would be 1000px wide the cells in the 2nd row would be 500px EACH the cell in the 3rd row would be 1000px the cells in the 4th row would be 250px EACH and the cells in the 5th row would be 333px, 334px, and 333px each (left-to-right) I figured out I could use colspan for the first 4 rows, but the 5th (with 3 cells) would require a non-integer value. The cells in the 5th row won't expand beyond their column without colspan that I can tell... trying the width:## CSS code inside a div tag for each cell inside the td tag creating a class or classes that define the cell widths id-ing each cell, with or without a div tag, and defining widths individually and adjuting the table-layout: option After several days, I'm now at my rope's end. The only thing I can come up with is deliberately tripling the number of cells in each row so that colspan would be all integer values. That sounds inconvenient and unreasonably difficult to format the table the way I'd like. It's a table of Batman movies for a website -- a practice website I'm building, in order to learn HTML/CSS. I've been working on-and-off with HTML for several months, and CSS for a few weeks. PS: It is not being used for layout, I am simply trying to adjust the layout of the table itself.

  • How to get multiple counts with one SQL query?

    - by Crobzilla
    I am wondering how to write this query. I know this actual syntax is bogus, but it will help you understand what I am wanting. I need it in this format, because it is part of a much bigger query. SELECT distributor_id, COUNT(*) AS TOTAL, COUNT(*) WHERE level = 'exec', COUNT(*) WHERE level = 'personal' I need this all returned in one query. Also, it need to be in one row, so the following won't work: 'SELECT distributor_id, COUNT(*) GROUP BY distributor_id'

  • HMAC URLs instead of login?

    - by Tres
    In implementing my site (a Rails site if it makes any difference), one of my design priorities is to relieve the user of the need to create yet another username and password while still providing useful per-user functionality. The way I am planning to do this is: User enters information on the site. Information is associated with the user via server-side session. User completes entering information, server sends an access URL via e-mail to the user roughly in the form of: http://siteurl/<user identifier>/<signature: HMAC(secret + salt + user identifier)> User clicks URL, site looks up user ID and salt and computes the HMAC with the server-stored secret and authenticates if the computed HMAC and signature match. My question is: is this a reasonably secure way to accomplish what I'm looking to do? Are there common attacks that would render it useless? Is there a compelling reason to abandon my desire to avoid a username/password? Is there a must-read book or article on the subject? Note that I'm not dealing with credit card numbers or anything exceedingly private, but I would still like to keep the information reasonably secure.

  • Facebook insights for websites does not match on-site Facebook button counts

    - by Will
    I use Facebook Insights for websites and Facebook buttons on my site. However, the data reported by the two do not match. It always seems to be the case that the count reported by the buttons is significantly higher than the count reported in Facebook Insights. For example, this page http://www.appmyworld.com/blog/top-5-iphone-and-ipad-apps-of-the-week-10412.html has a count of 52 for Facebook which is made up of 19 likes, 21 shares and 12 comments according to AddThis and confirmed by http://sharedcount.com However, going into Facebook Insights for my website and looking at that specific page it shows only 4 total actions which is made up of 1 like and 3 shares. At the very least I would expect it to show a total count of 40 made up of 19 likes and 21 shares (I'm not sure it would track the 12 comments). Any thoughts on why this may be happening? My concern is if our website is not getting credit for the Facebook activity?

  • Get Image Source URLs from a Different Page Using JS

    - by SDD
    Everyone: I'm trying to grab the source URLs of images from one page and use them in some JavaScript in another page. I know how to pull in images using JQuery .load(). However, rather than load all the images and display them on the page, I want to just grab the source URLs so I can use them in a JS array. Page 1 is just a page with images: <html> <head> </head> <body> <img id="image0" src="image0.jpg" /> <img id="image1" src="image1.jpg" /> <img id="image2" src="image2.jpg" /> <img id="image3" src="image3.jpg" /> </body> </html> Page 2 contains my JS. (Please note that the end goal is to load images into an array, randomize them, and using cookies, show a new image on page load every 10 seconds. All this is working. However, rather than hard code the image paths into my javascript as shown below, I'd prefer to take the paths from Page 1 based on their IDs. This way, the images won't always need to be titled "image1.jpg," etc.) <script type = "text/javascript"> var days = 730; var rotator = new Object(); var currentTime = new Date(); var currentMilli = currentTime.getTime(); var images = [], index = 0; images[0] = "image0.jpg"; images[1] = "image1.jpg"; images[2] = "image2.jpg"; images[3] = "image3.jpg"; rotator.getCookie = function(Name) { var re = new RegExp(Name+"=[^;]+", "i"); if (document.cookie.match(re)) return document.cookie.match(re)[0].split("=")[1]; return''; } rotator.setCookie = function(name, value, days) { var expireDate = new Date(); var expstring = expireDate.setDate(expireDate.getDate()+parseInt(days)); document.cookie = name+"="+value+"; expires="+expireDate.toGMTString()+"; path=/"; } rotator.randomize = function() { index = Math.floor(Math.random() * images.length); randomImageSrc = images[index]; } rotator.check = function() { if (rotator.getCookie("randomImage") == "") { rotator.randomize(); document.write("<img src=" + randomImageSrc + ">"); rotator.setCookie("randomImage", randomImageSrc, days); rotator.setCookie("timeClock", currentMilli, days); } else { var writtenTime = parseInt(rotator.getCookie("timeClock"),10); if ( currentMilli > writtenTime + 10000 ) { rotator.randomize(); var writtenImage = rotator.getCookie("randomImage") while ( randomImageSrc == writtenImage ) { rotator.randomize(); } document.write("<img src=" + randomImageSrc + ">"); rotator.setCookie("randomImage", randomImageSrc, days); rotator.setCookie("timeClock", currentMilli, days); } else { var writtenImage = rotator.getCookie("randomImage") document.write("<img src=" + writtenImage + ">"); } } } rotator.check() </script> Can anyone point me in the right direction? My hunch is to use JQuery .get(), but I've been unsuccessful so far. Please let me know if I can clarify!

  • Which style is preferable when writing this boolean expression?

    - by Jeppe Stig Nielsen
    I know this question is to some degree a matter of taste. I admit this is not something I don't understand, it's just something I want to hear others' opinion about. I need to write a method that takes two arguments, a boolean and a string. The boolean is in a sense (which will be obvious shortly) redundant, but it is part of a specification that the method must take in both arguments, and must raise an exception with a specific message text if the boolean has the "wrong" value. The bool must be true if and only if the string is not null or empty. So here are some different styles to write (hopefully!) the same thing. Which one do you find is the most readable, and compliant with good coding practice? // option A: Use two if, repeat throw statement and duplication of message string public void SomeMethod(bool useName, string name) { if (useName && string.IsNullOrEmpty(name)) throw new SomeException("..."); if (!useName && !string.IsNullOrEmpty(name)) throw new SomeException("..."); // rest of method } // option B: Long expression but using only && and || public void SomeMethod(bool useName, string name) { if (useName && string.IsNullOrEmpty(name) || !useName && !string.IsNullOrEmpty(name)) throw new SomeException("..."); // rest of method } // option C: With == operator between booleans public void SomeMethod(bool useName, string name) { if (useName == string.IsNullOrEmpty(name)) throw new SomeException("..."); // rest of method } // option D1: With XOR operator public void SomeMethod(bool useName, string name) { if (!(useName ^ string.IsNullOrEmpty(name))) throw new SomeException("..."); // rest of method } // option D2: With XOR operator public void SomeMethod(bool useName, string name) { if (useName ^ !string.IsNullOrEmpty(name)) throw new SomeException("..."); // rest of method } Of course you're welcome to suggest other possibilities too. Message text "..." would be something like "If 'useName' is true a name must be given, and if 'useName' is false no name is allowed".

  • Possible to lock attribute write access by Doors User?

    - by Philip Nguyen
    Is it possible to programmatically lock certain attributes based on the user? So certain attributes can be written to by User2 and certain attributes cannot be written to by User2. However, User1 may have write access to all attributes. What is the most efficient way of accomplishing this? I have to worry about not taking up too many computational resources, as I would like this to be able to work on quite large modules.

  • Select number of rows for each group where two column values makes one group

    - by Fábio Antunes
    I have a two select statements joined by UNION ALL. In the first statement a where clause gathers only rows that have been shown previously to the user. The second statement gathers all rows that haven't been shown to the user, therefore I end up with the viewed results first and non-viewed results after. Of course this could simply be achieved with the same select statement using a simple ORDER BY, however the reason for two separate selects is simple after you realize what I hope to accomplish. Consider the following structure and data. +----+------+-----+--------+------+ | id | from | to | viewed | data | +----+------+-----+--------+------+ | 1 | 1 | 10 | true | .... | | 2 | 10 | 1 | true | .... | | 3 | 1 | 10 | true | .... | | 4 | 6 | 8 | true | .... | | 5 | 1 | 10 | true | .... | | 6 | 10 | 1 | true | .... | | 7 | 8 | 6 | true | .... | | 8 | 10 | 1 | true | .... | | 9 | 6 | 8 | true | .... | | 10 | 2 | 3 | true | .... | | 11 | 1 | 10 | true | .... | | 12 | 8 | 6 | true | .... | | 13 | 10 | 1 | false | .... | | 14 | 1 | 10 | false | .... | | 15 | 6 | 8 | false | .... | | 16 | 10 | 1 | false | .... | | 17 | 8 | 6 | false | .... | | 18 | 3 | 2 | false | .... | +----+------+-----+--------+------+ Basically I wish all non viewed rows to be selected by the statement, that is accomplished by checking weather the viewed column is true or false, pretty simple and straightforward, nothing to worry here. However when it comes to the rows already viewed, meaning the column viewed is TRUE, for those records I only want 3 rows to be returned for each group. The appropriate result in this instance should be the 3 most recent rows of each group. +----+------+-----+--------+------+ | id | from | to | viewed | data | +----+------+-----+--------+------+ | 6 | 10 | 1 | true | .... | | 7 | 8 | 6 | true | .... | | 8 | 10 | 1 | true | .... | | 9 | 6 | 8 | true | .... | | 10 | 2 | 3 | true | .... | | 11 | 1 | 10 | true | .... | | 12 | 8 | 6 | true | .... | +----+------+-----+--------+------+ As you see from the ideal result set we have three groups. Therefore the desired query for the viewed results should show a maximum of 3 rows for each grouping it finds. In this case these groupings were 10 with 1 and 8 with 6, both which had three rows to be shown, while the other group 2 with 3 only had one row to be shown. Please note that where from = x and to = y, makes the same grouping as if it was from = y and to = x. Therefore considering the first grouping (10 with 1), from = 10 and to = 1 is the same group if it was from = 1 and to = 10. However there are plenty of groups in the whole table that I only wish the 3 most recent of each to be returned in the select statement, and thats my problem, I not sure how that can be accomplished in the most efficient way possible considering the table will have hundreds if not thousands of records at some point. Thanks for your help. Note: The columns id, from, to and viewed are indexed, that should help with performance. PS: I'm unsure on how to name this question exactly, if you have a better idea, be my guest and edit the title.

  • MVC paths in Extjs

    - by Oleg
    I have got a ExtJs application (MVC). So, I define many controllers, models, views and stores. At now, the structure of my project is not easy. For example my model: Ext.define('KP.model.account.AccountList', { extend: 'Ext.data.Model', fields: ['parameter', 'string_value'] }); I define my store with model like this: Ext.define('KP.store.account.AccountList', { extend: 'Ext.data.Store', alias: 'store.s_AccountList', model: 'KP.model.account.AccountList', ...................................... }); If I want to move some .js files, I must rewrite many paths in classes definitions. So, how can I declare my classes (by alias maybe) and use them more effectively? It's need, If I move files on files tree. Thanks!

  • How to use Enquire.Js?

    - by big_smile
    Enquire.js is a Javascipt that re-creates CSS media queries for Javascripts. This means you can wrap your Javascripts in Media Queries. (Just like you would wrap CSS in Media Queries). I'm not quite sure how to use it. This tutorial says this: enquire.register("max-width: 960px", function() { // put your code here }); However, when I follow that, my code stops working. Here is an example of some Jquery Tabs without Enquire.JS. It works fine. Here are the same tabs, but with Enquire.JS added. Now it stops working. I've experimented with different variations of the code, but none of them work. What am I doing wrong? I think you might have place the Jquery Tab code in a separate file and then link to that file from within Enquire.Js, but I'm not sure how you would do that. (Although it would be handy to know as I'd imagine it would let you keep your scripts be more reusable). PS. This is not a criticism of Enquire.Js. I know that the problem lies squarely with my lack of proficiency in Javascript! I did spend a couple of hours searching for a solution, but couldn't find anything. Thanks for any help!

  • AngularJS: Using Shared Service(with $resource) to share data between controllers, but how to define callback functions?

    Note: I also posted this question on the AngularJS mailing list here: https://groups.google.com/forum/#!topic/angular/UC8_pZsdn2U Hi All, I'm building my first AngularJS app and am not very familiar with Javascript to begin with so any guidance will be much appreciated :) My App has two controllers, ClientController and CountryController. In CountryController, I'm retrieving a list of countries from a CountryService that uses the $resource object. This works fine, but I want to be able to share the list of countries with the ClientController. After some research, I read that I should use the CountryService to store the data and inject that service into both controllers. This was the code I had before: CountryService: services.factory('CountryService', function($resource) { return $resource('http://localhost:port/restwrapper/client.json', {port: ':8080'}); }); CountryController: //Get list of countries //inherently async query using deferred promise $scope.countries = CountryService.query(function(result){ //preselected first entry as default $scope.selected.country = $scope.countries[0]; }); And after my changes, they look like this: CountryService: services.factory('CountryService', function($resource) { var countryService = {}; var data; var resource = $resource('http://localhost:port/restwrapper/country.json', {port: ':8080'}); var countries = function() { data = resource.query(); return data; } return { getCountries: function() { if(data) { console.log("returning cached data"); return data; } else { console.log("getting countries from server"); return countries(); } } }; }); CountryController: $scope.countries = CountryService.getCountries(function(result){ console.log("i need a callback function here..."); }); The problem is that I used to be able to use the callback function in $resource.query() to preselect a default selection, but now that I've moved the query() call to within my CountryService, I seemed to have lost what. What's the best way to go about solving this problem? Thanks for your help, Shaun

  • Multiline editable textarea in SVG

    - by Timo
    I'm trying to implement multiline editable textfield in SVG. I have the following code in http://jsfiddle.net/ca4d3/ : <svg width="1000" height="1000" overflow="scroll"> <g transform="rotate(5)"> <rect width="300" height="400" fill="#22DD22" fill-opacity="0.5"/> </g> <foreignObject x="10" y="10" overflow="visible" width="10000" height="10000" requiredFeatures="http://www.w3.org/TR/SVG11/feature#Extensibility"> <p style="display:table-cell;padding:10px;border:1px solid red; background-color:white;opacity:0.5;font-family:Verdana; font-size:20px;white-space: pre; word-wrap: normal; overflow: visible; overflow-y: visible; overflow-x:visible;" contentEditable="true" xmlns="http://www.w3.org/1999/xhtml"> Write here some text. Be smart and select some word. If you wanna be really COOL, paste here something cool! </p> </foreignObject> </svg> In newest Chrome, Safari and Firefox the code works in some way, but in Opera and IE 9 not. The goal is that: 0) Works in newest Chrome, Safari, Firefox, Opera and IE and if ever possible in some pads. 1) White-spaces are preserved and text wraps only on newline char (works in Chrome, Safari and Firefox, but not in Opera and IE 9 *). 2) The textfield is editable (in the same reliable and stabile way as textareas and contenteditable p elements in html) and height and width is expanded to fit text (works in Chrome, Safari and Firefox, but not in Opera and IE 9 *). 3) Texfield can be transformed (rotated, skewed, translated) while maintaining text editability (Tested rotation, but not work in any browser *). EDIT: Foreignobject rotation works on Firefox 15.0.1, but not in Safari 5.1.7 (6534.57.2), Chrome 22.0.1229.79, Opera 12.02, IE 9. Tested on Mac OS X 10.6.8. 4) Textfield can be clipped and masked while not necessarily maintaining text editability (not yet tested). *) using above code These all can be achieved using Flash, but Flash has so severe problems that it is not suitable for my purposes (after every little change in code, all have to be compiled again using Flex, which is slow, font size has limits, tracking technique is pixeloriented, not relative to em size etc.) and there still are differences across platforms. And I want to give a try to SVG! GUESTION: Can I achieve my goals 0-4 with current SVG support in browsers? Is coming SVG 2.0 for some help in this case? EDIT: Changed display:table to display:table-cell (and added new jsfiddle), because display:table made the field to loses focus when pressed arrow-up on first text row.

  • Client-Side Dynamic Removal of <script> Tags in <head>

    - by merv
    Is it possible to remove script tags in the <head> of an HTML document client-side and prior to execution of those tags? On the server-side I am able to insert a <script> above all other <script> tags in the <head>, except one, and I would like to be able to remove all subsequent scripts. I do not have the ability to remove <script> tags from the server side. What I've tried: (function (c,h) { var i, s = h.getElementsByTagName('script'); c.log("Num scripts: " + s.length); i = s.length - 1; while(i > 1) { h.removeChild(s[i]); i -= 1; } })(console, document.head); However, the logged number of scripts comes out to only 1, since (as @ryan pointed out) the code is being executed prior to the DOM being ready. Although wrapping the code above in a document.ready event callback does enable proper calculation of the number of <script> tags in the <head>, waiting until the DOM is ready fails to prevent the scripts from loading. Is there a reliable means of manipulating the HTML prior to the DOM being ready? Background If you want more context, this is part of an attempt to consolidate scripts where no option for server-side aggregation is available. Many of the JS libraries being loaded are from a CMS with limited configuration options. The content is mostly static, so there is very little concern about manually aggregating the JavaScript and serving it from a different location. Any suggestions for alternative applicable aggregation techniques would also be welcome.
