  • Many DIVs inside parent DIV, CSS height issue

    - by Benjamin
    Hi everyone, I am putting together a dynamic photo gallery and getting stuck trying to place thumbnails. Basically I am trying to place each thumbnail and caption in its own DIV, floated to the left. The thumbnails are working just as I want them to but for some reason the parent DIV refuses to cover the height of the thumbnail area. Here is the CSS I am using.. #galleryBox { width: 650px; background: #fff; margin: auto; padding: 5px; text-align: center; } .item { display: block; margin: 10px; padding: 10px; float: left; background: #353535; min-width: 120px; } .label { display: block; color: #fff; } I have tried height: auto and that hasn't done anything. Here is what I am trying to style: <div id="galleryBox" class="ui-corner-all"> <div class="item ui-corner-all"> <img src="http://tapp-essexvfd.org/images/ajax-loader.gif" alt="test"/><br/> <p><span class="label">Testing</span></p> </div> <div class="item ui-corner-all"> <img src="http://tapp-essexvfd.org/images/ajax-loader.gif" alt="test"/><br/> <p><span class="label">Testing</span></p> </div> <div class="item ui-corner-all"> <img src="http://tapp-essexvfd.org/images/ajax-loader.gif" alt="test"/><br/> <p><span class="label">Testing</span></p> </div> <div class="item ui-corner-all"> <img src="http://tapp-essexvfd.org/images/ajax-loader.gif" alt="test"/><br/> <p><span class="label">Testing</span></p> </div> <div class="item ui-corner-all"> <img src="http://tapp-essexvfd.org/images/ajax-loader.gif" alt="test"/><br/> <p><span class="label">Testing</span></p> </div> <div class="item ui-corner-all"> <img src="http://tapp-essexvfd.org/images/ajax-loader.gif" alt="test"/><br/> <p><span class="label">Testing</span></p> </div> <div class="item ui-corner-all"> <img src="http://tapp-essexvfd.org/images/ajax-loader.gif" alt="test"/><br/> <p><span class="label">Testing</span></p> </div> </div> Thanks!

  • Python logger dynamic filename

    - by sharjeel
    I want to configure my Python logger in such a way so that each instance of logger should log in a file having the same name as the name of the logger itself. e.g.: log_hm = logging.getLogger('healthmonitor') log_hm.info("Testing Log") # Should log to /some/path/healthmonitor.log log_sc = logging.getLogger('scripts') log_sc.debug("Testing Scripts") # Should log to /some/path/scripts.log log_cr = logging.getLogger('cron') log_cr.info("Testing cron") # Should log to /some/path/cron.log I want to keep it generic and dont want to hardcode all kind of logger names I can have. Is that possible?

  • What is dot and hash symbols mean in JQuery

    - by kwokwai
    Hi all, I feel confused of the dot and hash symbols in the following example: <DIV ID="row"> <DIV ID="c1"> <Input type="radio" name="testing" id="testing" VALUE="1">testing1 </DIV> </DIV> Code 1: $('#row DIV').mouseover(function(){ $('#row DIV).addClass('testing'); }); Code 2 $('.row div').mouseover(function(){ $(this).addClass('testing'); });? Codes 1 and 2 look very similar, and so it makes me so confused that when I should use ".row div" to refer to a specific DIV instead of using "#row div" ?

  • CM and Agile validation process of merging to the Trunk?

    - by LoneCM
    Hello All, We are a new Agile shop and we are encountering an issue that I hope others have seen. In our process, the Trunk is considered an integration branch; it does not have to be releasable, but it does have to be stable and functional for others to branch off of. We create Feature branches of the Trunk for new development. All work and testing occurs in these branches. An individual branch pulls up as needed to stay integrated with the Trunk as other features that are accepted and are committed. But now we have numerous feature branches. Each are focused, have a short life cycle, and are pushed to the trunk as they are completed, so we not debating the need for the branches and trying very much to be Agile. My issue comes in here: I require that the branches pull up from the Trunk at the end of their life cycle and complete the validation, regression testing and handle all configuration issues before pushing to the trunk. Once reintegrated into the Trunk, I ask for at least a build and an automated smoke test. However, I am now getting push back on the Trunk validation. The argument is that the developers can merge the code and not need the QA validation steps because they already complete the work in the feature branch. Therefore, the extra testing is not needed. I have attempted to remind management of the numerous times "brainless" merges have failed. Thier solution is to instead of build and regression testing to have the developer diff the Feature branch and the newly merged Trunk. That process in thier mind would replace the regression testing I asked for. So what do you require when you reintegrate back to the Trunk? What are the issues that we will encounter if we remove this step and replace with the diff? Is the cost of staying Agile the additional work of the intergration of the branches? Thanks for any input. LoneCM

  • Is there a way to keep a selenium session persistent accross multiple tests?

    - by Nick
    I am testing a django application's frontend with selenium and that's first time I use it. I have multiple tests that test things after user logged in. I want them to be separate tests, but I want to have only log in once, is that possible? (As oppose to what I do right now: I log in first, then execute my testing actions of test1, then log in again and execute my testing actions for test2, etc.)

  • TDD Example for Business Apps

    - by Jimmo
    I understand the general idea about unit testing and have used it in scenarios where complex interactions were happening in a system, but I still have a question about all of those principles coming together. We are cautioned about not testing the framework, or the database. Good UI design does not lend itself to non-human testing. UI interaction in general is excluded in MVC frameworks. In many apps what is left?. 37signals talks about extensive unit testing, but in an app like Basecamp or Backpack, what exactly are the types of things being tested through appropriate unit tests? What would 100% code coverage mean in that scenario?

  • How to test custom handler500?

    - by Gr1N
    I write my handler for server errors and define it at root urls.py: handler500 = 'myhandler' And I want to write unittest for testing how it works. For testing I write view with error and define it in test URLs configuration, when I make request to this view in browser I see my handler and receive status code 500, but when I launch test that make request to this view I see stack trace and my test failed. Have you some ideas for testing handler500 by unittests?

  • Can a program have a few IFs and only one Else structures?

    - by kwokwai
    Hi all, When I was doing some JQuery and PHP, I noticed the If-else patterns were treated differently and varied from one language to another. Say I got a simple input text field in a HTML and I was using some Ifs and Elses to check the value input into the text field. Text: <input type="text" name="testing"/> In JQuery, I got some codes as follows: if($("#testing").val()==1){ //do something } if($("#testing").val()=="add"){ //do something } else{ //do something } if($("#testing").val()=="hello"){ //do something } How come JQuery and PHP treated the Else statement differently? I mean in JQuery, the third If statement was still proceeded even if it had gone to the Else statement, but it stopped after the Else statement when I repeated the code in PHP script.

  • Change cookies when doing jQuery.ajax requests in Chrome Extensions

    - by haskellguy
    I have wrote a plugin for facebook that sends data to testing-fb.local. The request goes through if the user is logged in. Here is the workflow: User logs in from testing-fb.local Cookies are stored When $.ajax() are fired from the Chrome extension Chrome extension listen with chrome.webRequest.onBeforeSendHeaders Chrome extension checks for cookies from chrome.cookies.get Chrome changes the Set-Cookies header to be sent And the request goes through. I wrote this part of code that shoud be this: function getCookies (callback) { chrome.cookies.get({url:"https://testing-fb.local", name: "connect.sid"}, function(a){ return callback(a) }) } chrome.webRequest.onBeforeSendHeaders.addListener( function(details) { getCookies(function(a){ // Here something happens }) }, {urls: ["https://testing-fb.local/*"]}, ['blocking']); Here is my manifest.json: { "name": "test-fb", "version": "1.0", "manifest_version": 1, "description": "testing", "permissions": [ "cookies", "webRequest", "tabs", "http://*/*", "https://*/*" ], "background": { "scripts": ["background.js"] }, "content_scripts": [ { "matches": ["http://*.facebook.com/*", "https://*.facebook.com/*"], "exclude_matches" : [ "*://*.facebook.com/ajax/*", "*://*.channel.facebook.tld/*", "*://*.facebook.tld/pagelet/generic.php/pagelet/home/morestories.php*", "*://*.facebook.tld/ai.php*" ], "js": ["jquery-1.8.3.min.js", "allthefunctions.js"] } ] } In allthefunction.js I have the $.ajax calls, and in background.js is where I put the code above which however looks not to run.. In summary, I have not clear: What I should write in Here something happens If this strategy is going to work Where should I put this code?

  • Implementing a wrapping wire (like the Worms Ninja Rope) in a 2D physics engine

    - by Andrew Russell
    I've been trying out some rope-physics recently, and I've found that the "standard" solution - making a rope from a series of objects strung together with springs or joints - is unsatisfying. Especially when rope swinging is relevant to gameplay. I don't really care about a rope's ability to wrap up or sag (this can be faked for visuals anyway). For gameplay, what is important is the ability for the rope to wrap around the environment and then subsequently unwrap. It doesn't even have to behave like rope - a "wire" made up of straight line segments would do. Here's an illustration: This is very similar to the "Ninja Rope" from the game Worms. Because I'm using a 2D physics engine - my environment is made up of 2D convex polygons. (Specifically I am using SAT in Farseer.) So my question is this: How would you implement the "wrapping" effect? It seems pretty obvious that the wire will be made up of a series of line segments that "split" and "join". And the final (active) segment of that line, where the moving object attaches, will be a fixed-length joint. But what is the maths / algorithm involved for determining when and where the active line segment needs to be split? And when it needs to be joined with the previous segment? (Previously this question also asked about doing this for a dynamic environment - I've decided to split that off into other questions.)

  • Getting Query Parameters in Javascript

    - by PhubarBaz
    I find myself needing to get query parameters that are passed into a web app on the URL quite often. At first I wrote a function that creates an associative array (aka object) with all of the parameters as keys and returns it. But then I was looking at the revealing module pattern, a nice javascript design pattern designed to hide private functions, and came up with a way to do this without even calling a function. What I came up with was this nice little object that automatically initializes itself into the same associative array that the function call did previously. // Creates associative array (object) of query params var QueryParameters = (function() {     var result = {};     if (window.location.search)     {         // split up the query string and store in an associative array         var params = window.location.search.slice(1).split("&");         for (var i = 0; i < params.length; i++)         {             var tmp = params[i].split("=");             result[tmp[0]] = unescape(tmp[1]);         }     }     return result; }()); Now all you have to do to get the query parameters is just reference them from the QueryParameters object. There is no need to create a new object or call any function to initialize it. var debug = (QueryParameters.debug === "true"); or if (QueryParameters["debug"]) doSomeDebugging(); or loop through all of the parameters. for (var param in QueryParameters) var value = QueryParameters[param]; Hope you find this object useful.

  • printable PHP manual - 'all but the Function Reference section'

    - by JW01
    My Motivation I find it easier to learn things by reading 'offline'. I'd like to lean back and read the narrative part of a paper version of the official php manual. My Scuppered Plan My plan was to download the manual, print all but the Function Reference section and then read it. I have downloaded the "Single HTML file" version of the manual from the php.net download page. (That version did not contain any images, so I patched-in the ones from the Many HTML files version with no problem.) My plan was to open that "Single HTML file" in an HTML editor, delete the Function Reference section then print it out. Unfortunately, although I have tried three different editors, I have not been able to successfully load-up that massive html file to be able to edit it. Its about (~40MB). I started to look into the phpdoc framework with a view to rendering my own html docs from the source...but that's a steep learning curve for a newby..and is a last resort. I would use a file splitter, but they tend to split files crudely with no regard for html/xml/xhtml sematics. So the question is... Does anyone know know where you can download the php manual in a version that is a kind of half-way house between the 'Single HTML file' and the 'Many HTML files'? Ideally with the docs split into 3 parts: File 1 - stuff before the function reference File 2 - function reference File 3 - stuff after the function reference Or Can you suggest any editors/tools will enable me to split up this file myself?

  • Algorithm to reduce calls to mapping API

    - by aidan
    A random distribution of points lies on a map. This data lies behind an API, and I want to grab the complete set of points within a given bounding box. I can query the API with the bounding box and the API will return the set of points that fall within that box. The problem is that the API will limit the result set to 10 items, with no pagination and no indication if there are more points that have been omitted. So I made a recursive algorithm that takes a bounding box and requests the points that lie within it. If the result set is exactly 10 items, then I split the bounding box into four quadrants and recurse. It works fine but my question is this: if want to minimize the number of API calls, what is the optimal way to split the bounding box? Splitting it into quadrants was just an arbitrary decision. When there are a lot of points on the map, I have to drill down many levels before I start getting meaningful results. So I imagine it might be faster to split the box into, say, 9, 16, or more sections. But if I do that, then I eventually get to a point where a lot of requests are returning 0 results which isn't so efficient. Also, does the size of the limit on the results set affect the answer? (This is all assuming that I have no prior knowledge of nominal point density in the bounding box)

  • Hosting several HTTP servers on single domain name

    - by Nakilon
    Several people have got a single domain name server.company.com server, where they are now supposed to host their infrastructure or temporal projects, written in different ways even in different programming languages. How do they divide the domain? Split into subdomains: john.server.company.com, kate.server.company.com, etc. This would need a lot of admins' assistance, time, etc. -- there would be no way for John and Kate to do it themselves. Split into url namespaces: server.company.com/john/, server.company.com/kate/, etc. Pro: They now can make a single welcome page at root with any additional info (if they need?) Con: Each server would need to know their namespace string constant, and hrefs like / whould need patching. Split into ports: server.company.com:8080, server.company.com:8081, etc. and make a single :80 welcome page. Pro: They still can make a single welcome page at :80 Con: ??? I would like to know more pros and cons for 2 and 3 solution.

  • Possible to draw a select portion of a render target? (in XNA)

    - by TheBroodian
    I'm going to try to do this in reverse fashion and skip straight to the punch line, and then give the back story afterward: Is it possible to, after drawing a scene to a RenderTarget2D, only draw a select portion of the RenderTarget2D, if I don't want the entire thing? I'm using xTile to manage world data in my game (it's a great piece of work, colinvella [xTile's author] has made an amazing product), and for the most part it works great. xTile supports parallax effects in its layers to add some wonderful depth to 2d scenes, which was great, until I implemented a dynamic split-screen system into my game. Wanted to make a co-op game that wouldn't require players to be in close proximity to each other, so I made it so that if the players separate too far apart, the singular full-screen viewport 'snaps-apart', and is replaced by two split-screen viewports, which then smoothly transition to their respective player targets. The effect is pretty smooth aside from the part where the parallax backgrounds become skewed once the viewports split, because xTile's ratio for handling parallax effects is dependent upon viewport size. This is unfortunate, because the effect would otherwise be really snazzy, but the backgrounds become pretty heavily affected when the game goes from single-viewport to multi-viewport. So, Colinvella suggests using rendertargets to record the scene at full viewport size, and then only drawing a portion of it. But as far as I can tell, that isn't even possible? That being said, I've never even used render targets before, so I'm still learning, hence the question here.

  • jQuery load Google Visualization API with AJAX

    - by Curro
    Hello. There is an issue that I cannot solve, I've been looking a lot in the internet but found nothing. I have this JavaScript that is used to do an Ajax request by PHP. When the request is done, it calls a function that uses the Google Visualization API to draw an annotatedtimeline to present the data. The script works great without AJAX, if I do everything inline it works great, but when I try to do it with AJAX it doesn't work!!! The error that I get is in the declaration of the "data" DataTable, in the Google Chrome Developer Tools I get a Uncaught TypeError: Cannot read property 'DataTable' of undefined. When the script gets to the error, everything on the page is cleared, it just shows a blank page. So I don't know how to make it work. Please help Thanks in advance $(document).ready(function(){ // Get TIER1Tickets $("#divTendency").addClass("loading"); $.ajax({ type: "POST", url: "getTIER1Tickets.php", data: "", success: function(html){ // Succesful, load visualization API and send data google.load('visualization', '1', {'packages': ['annotatedtimeline']}); google.setOnLoadCallback(drawData(html)); } }); }); function drawData(response){ $("#divTendency").removeClass("loading"); // Data comes from PHP like: <CSV ticket count for each day>*<CSV dates for ticket counts>*<total number of days counted> // So it has to be split first by * then by , var dataArray = response.split("*"); var dataTickets = dataArray[0]; var dataDates = dataArray[1]; var dataCount = dataArray[2]; // The comma separation now splits the ticket counts and the dates var dataTicketArray = dataTickets.split(","); var dataDatesArray = dataDates.split(","); // Visualization data var data = new google.visualization.DataTable(); data.addColumn('date', 'Date'); data.addColumn('number', 'Tickets'); data.addRows(dataCount); var dateSplit = new Array(); for(var i = 0 ; i < dataCount ; i++){ // Separating the data because must be entered as "new Date(YYYY,M,D)" dateSplit = dataDatesArray[i].split("-"); data.setValue(i, 0, new Date(dateSplit[2],dateSplit[1],dateSplit[0])); data.setValue(i, 1, parseInt(dataTicketArray[i])); } var annotatedtimeline = new google.visualization.AnnotatedTimeLine(document.getElementById('divTendency')); annotatedtimeline.draw(data, {displayAnnotations: true}); }

  • Infinite loop when adding a row to a list in a class in python3

    - by Margaret
    I have a script which contains two classes. (I'm obviously deleting a lot of stuff that I don't believe is relevant to the error I'm dealing with.) The eventual task is to create a decision tree, as I mentioned in this question. Unfortunately, I'm getting an infinite loop, and I'm having difficulty identifying why. I've identified the line of code that's going haywire, but I would have thought the iterator and the list I'm adding to would be different objects. Is there some side effect of list's .append functionality that I'm not aware of? Or am I making some other blindingly obvious mistake? class Dataset: individuals = [] #Becomes a list of dictionaries, in which each dictionary is a row from the CSV with the headers as keys def field_set(self): #Returns a list of the fields in individuals[] that can be used to split the data (i.e. have more than one value amongst the individuals def classified(self, predicted_value): #Returns True if all the individuals have the same value for predicted_value def fields_exhausted(self, predicted_value): #Returns True if all the individuals are identical except for predicted_value def lowest_entropy_value(self, predicted_value): #Returns the field that will reduce <a href="http://en.wikipedia.org/wiki/Entropy_%28information_theory%29">entropy</a> the most def __init__(self, individuals=[]): and class Node: ds = Dataset() #The data that is associated with this Node links = [] #List of Nodes, the offspring Nodes of this node level = 0 #Tree depth of this Node split_value = '' #Field used to split out this Node from the parent node node_value = '' #Value used to split out this Node from the parent Node def split_dataset(self, split_value): fields = [] #List of options for split_value amongst the individuals datasets = {} #Dictionary of Datasets, each one with a value from fields[] as its key for field in self.ds.field_set()[split_value]: #Populates the keys of fields[] fields.append(field) datasets[field] = Dataset() for i in self.ds.individuals: #Adds individuals to the datasets.dataset that matches their result for split_value datasets[i[split_value]].individuals.append(i) #<---Causes an infinite loop on the second hit for field in fields: #Creates subnodes from each of the datasets.Dataset options self.add_subnode(datasets[field],split_value,field) def add_subnode(self, dataset, split_value='', node_value=''): def __init__(self, level, dataset=Dataset()): My initialisation code is currently: if __name__ == '__main__': filename = (sys.argv[1]) #Takes in a CSV file predicted_value = "# class" #Identifies the field from the CSV file that should be predicted base_dataset = parse_csv(filename) #Turns the CSV file into a list of lists parsed_dataset = individual_list(base_dataset) #Turns the list of lists into a list of dictionaries root = Node(0, Dataset(parsed_dataset)) #Creates a root node, passing it the full dataset root.split_dataset(root.ds.lowest_entropy_value(predicted_value)) #Performs the first split, creating multiple subnodes n = root.links[0] n.split_dataset(n.ds.lowest_entropy_value(predicted_value)) #Attempts to split the first subnode.

  • Convert string from getline into a number

    - by haskellguy
    I am trying to create a 2D array with vectors. I have a file that has for each line a set of numbers. So what I did I implemented a split function that every time I have a new number (separated by \t) it splits that and add it to the vector vector<double> &split(const string &s, char delim, vector<double> &elems) { stringstream ss(s); string item; while (getline(ss, item, delim)) { cout << item << endl; double number = atof(item.c_str()); cout << number; elems.push_back(number); } return elems; } vector<double> split(const string &s, char delim) { vector<double> elems; split(s, delim, elems); return elems; } After that I simply iterate through it. int main() { ifstream file("./data/file.txt"); string row; vector< vector<double> > matrix; int line_count = -1; while (getline(file, row)) { line_count++; if (line_count <= 4) continue; vector<double> cols = split(row, '\t'); matrix.push_back(cols); } ... } Now my issues is in this bit here: while (getline(ss, item, delim)) { cout << item << endl; double number = atof(item.c_str()); cout << number; Where item.c_str() is converted to a 0. Shouldn't that be still a string having the same value as item? It works on a separate example if I do straight from string to c_string, but when I use this getline I end up in this error situation, hints?

  • How to compare DateTime Objects while looping through a list?

    - by Taniq
    I'm trying to loop through a list (csv) containing two fields; a name and a date. There are various duplicated names and various dates in the list. I'm trying to deduce for each name in the list, where there are multiple instances of the same name, which corresponding date is the latest. I realise, from looking at another answer, that I need to use the DateTime.Compare method which is fine, but my problem is working out which date is later. Once I know this I need to produce a file with unique names and the latest date relating to it. This is my first question which makes me a newbie. EDIT: Initially I thought it would be 'ok' to set the LatestDate object to a date that wouldn't show up in my file, therefore making any later dates in the file the LatestDate. Here's my coding so far: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; namespace flybe_overwriter { class Program { static DateTime currentDate; static DateTime latestDate = new DateTime(1000,1,1); static HashSet<string> uniqueNames = new HashSet<string>(); static string indexpath = @"e:\flybe test\indexing.csv"; static string[] indexlist = File.ReadAllLines(indexpath); static StreamWriter outputfile = new StreamWriter(@"e:\flybe test\match.csv"); static void Main(string[] args) { foreach (string entry in indexlist) { uniqueNames.Add(entry.Split(',')[0]); } HashSet<string>.Enumerator fenum = new HashSet<string>.Enumerator(); fenum = uniqueNames.GetEnumerator(); while (fenum.MoveNext()) { string currentName = fenum.Current; foreach (string line in indexlist) { currentDate = new DateTime(Convert.ToInt32(line.Split(',')[1].Substring(4, 4)), Convert.ToInt32(line.Split(',')[1].Substring(2, 2)), Convert.ToInt32(line.Split(',')[1].Substring(0, 2))); if (currentName == line.Split(',')[0]) { if(DateTime.Compare(latestDate.Date, currentDate.Date) < 1) { // Console.WriteLine(currentName + " " + latestDate.ToShortDateString() + " is earlier than " + currentDate.ToShortDateString()); } else if (DateTime.Compare(latestDate.Date, currentDate.Date) > 1) { // Console.WriteLine(currentName + " " + latestDate.ToShortDateString() + " is later than " + currentDate.ToShortDateString()); } else if (DateTime.Compare(latestDate.Date, currentDate.Date) == 0) { // Console.WriteLine(currentName + " " + latestDate.ToShortDateString() + " is the same as " + currentDate.ToShortDateString()); } } } } } } } Any help appreciated. Thanks.
