  • Geocoding autocomplete bias not working

    - by chris
    I'm using the following code to get the autocomplete functionality for an address input box using Google Maps API v3: function initializeAutocomplete() { var defaultBounds = new google.maps.LatLngBounds( new google.maps.LatLng(1.484016,103.575212), new google.maps.LatLng(1.233592,104.033618)); var input = document.getElementById('destStreet'); var myOptions = {bounds: defaultBounds, types: ['geocode']}; autocomplete = new google.maps.places.Autocomplete(input, myOptions); } The problem is that biasing doesn't seem to work as the first results are usually not relevant to the defined bounds (a country). I've seen a few apps working fine, so I'm wondering where the problem is. I came across the JQuery autocomplete plugin (http://code.google.com/p/geo-autocomplete/) which would seem like a good alternative since it has a region filter, but I'm unable to "install it" or use it because of my very limited knowledge (I learn by example). Could you please help me getting more relevant results with the above code or guide me through the implementation of the JQuery alternative? Of course I'm very open to other suggestions as well.

  • Are there programs that iteratively write new programs?

    - by chris
    For about a year I have been thinking about writing a program that writes programs. This would primarily be a playful exercise that might teach me some new concepts. My inspiration came from negentropy and the ability for order to emerge from chaos and new chaos to arise out of order in infinite succession. To be more specific, the program would start by writing a short random string. If the string compiles the programs will log it for later comparison. If the string does not compile the program will try to rewrite it until it does compile. As more strings (mini 'useless' programs) are logged they can be parsed for similarities and used to generate a grammar. This grammar can then be drawn on to write more strings that have a higher probability of compilation than purely random strings. This is obviously more than a little silly, but I thought it would be fun to try and grow a program like this. And as a byproduct I get a bunch of unique programs that I can visualize and call art. I'll probably write this in Ruby due to its simple syntax and dynamic compilation and then I will visualize in processing using ruby-processing. What I would like to know is: Is there a name for this type of programming? What currently exists in this field? Who are the primary contributors? BONUS! - In what ways can I procedurally assign value to output programs beyond compiles(y/n)? I may want to extend the functionality of this program to generate a program based on parameters, but I want the program to define those parameters through running the programs that compile and assigning meaning to the programs output. This question is probably more involved than reasonable for a bonus, but if you can think of a simple way to get something like this done in less than 23 lines or one hyperlink, please toss it into your response. I know that this is not quite meta-programming and from the little I know of AI and generative algorithms they are usually more goal oriented than what I am thinking. What would be optimal is a program that continually rewrites and improves itself so I don't have to ^_^

  • Prevent Rails link_to_remote multiple submits w Javascript

    - by Chris
    In a Rails project I need to keep a link_to_remote from getting double-clicked. It looks like :before and :after are my only choices - they get prepended/appended to the onclick Ajax call, respectively. But if I try something like: :before => "self.stopObserving()" t,he Ajax is never run. If I try it for :after the Ajax is run but the link never stops observing. The solutions I've seen rely on creating a variable and blocking the whole form, but there are multiple link_to_remote rows on this page and it is valid to click more than one of them at a time - just not the same one twice. One variable per row declared outside of link_to_remote seems very kludgey... Instead of using Prototype I originally tried plain Javascript first for this proof of concept - but it fails too: <a href="#" onclick="self.onclick = function(){alert('foo');};"click</a just puts up an alert when clicked - the lambda here does nothing? This next one is more like the desired goal and should only alert the first time. But instead it alerts every time: <a href="#" onclick="alert('bar'); self.onclick = function(){return false;};"click</a All ideas appreciated!

  • Best way to detect similar email addresses?

    - by Chris
    I have a list of ~20,000 email addresses, some of which I know to be fraudulent attempts to get around a "1 per e-mail" limit. ([email protected], [email protected], [email protected], etc...). I want to find similar email addresses for evaluation. Currently I'm using a levenshtein algorithm to check each e-mail against the others in the list and report any with an edit distance of less than 2. However, this is painstakingly slow. Is there a more efficient approach? The test code I'm using now is: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; using System.Threading; namespace LevenshteinAnalyzer { class Program { const string INPUT_FILE = @"C:\Input.txt"; const string OUTPUT_FILE = @"C:\Output.txt"; static void Main(string[] args) { var inputWords = File.ReadAllLines(INPUT_FILE); var outputWords = new SortedSet<string>(); for (var i = 0; i < inputWords.Length; i++) { if (i % 100 == 0) Console.WriteLine("Processing record #" + i); var word1 = inputWords[i].ToLower(); for (var n = i + 1; n < inputWords.Length; n++) { if (i == n) continue; var word2 = inputWords[n].ToLower(); if (word1 == word2) continue; if (outputWords.Contains(word1)) continue; if (outputWords.Contains(word2)) continue; var distance = LevenshteinAlgorithm.Compute(word1, word2); if (distance <= 2) { outputWords.Add(word1); outputWords.Add(word2); } } } File.WriteAllLines(OUTPUT_FILE, outputWords.ToArray()); Console.WriteLine("Found {0} words", outputWords.Count); } } }

  • Ctrl-Backspace Visual Studio 2010

    - by Chris Watts
    I recently upgraded to Visual Studio 2010 and found out that when i press Ctrl-Backspace on a empty line it will delete the line, which is what it did in 2008, but then it will also delete the last character on the line above. I have tried to see if there is any settings anywhere but i cant seem to find any. Does anyone know if you can change this or did they make it default in 2010 Im using C#, if that makes a difference.

  • Wordpress: Check if there are previous posts before displaying link

    - by Chris Armstrong
    I'm using the following code to display a 'previous posts' link on my Wordpress blog. <nav> <ul> <li><?php previous_posts_link('Newer Entries &raquo;') ?></li> </ul </nav> Problem is, when there ARN'T any previous posts, while the link doesn't display, I still get <nav> <ul> <li><</li> </ul </nav> Printed out. Is there an if() statement I could wrap around it all so it checks if there are any previous posts, and only prints it out if there are?

  • Adding controls dynamically at design time vb.net

    - by chris
    I have been developing some custom smart tags. I am using a DesignerActionMethodItem which gets me to a fired method in code. When I try to hit the controls.Add the control is added but it seems the designer is unaware of it. It is never serialized and it goes away when the form is refreshed in the designer. Any help would be greatly appreciated. I am sort of stuck and google hasn't helped me. Please don't send me anything about smart tags that has nothing to do with adding controls dynamically at design time, I have already read so many looking for this.

  • What is the Browser version of a WebBrowser control in Windows Forms

    - by Chris Roberts
    I'm building a Windows Forms application which makes use of the WebBrowser control. Can anyone tell me what rendering engine the control uses? Is it fixed based on the version of the .NET framework I'm developing against or is it based on the version of IE installed on the client's machine? Does the client even need IE? In other words, if a website looks right in my application on my machine, is it reasonably safe to assume it'll render right on everyone else's machine? Thanks!

  • Why are my Flex resource bundles not being loaded?

    - by Chris R
    I have an Actionscript module in the flex source folder filterModules, which is one of two additional source folders in my project (the main source folder is reports, but I'm not dealing with anything in there right now). Here's the MXML content that references the resources. ... This array is assigned to the dataProvider field of a ComboBox. It's not bound using the bindings, presumably for reasons that made sense to the original developer, and it'd be nontrivial to change the class to make that happen. I additionally have a resource property file in a folder resources/en_US and I have the source folder resources/{locale} in the project source settings. My additional compiler options are -locale en_US. The resource property file is resources/en_US/labels.properties (All paths are relative to the flash builder project root) and contains (amongst other things) these keys: metric.q3 = Overall Satisfaction metric.q5 = Personnel metric.q9a = Issue Resolution metric.q42 = Visit Duration Sat metric.q34 = Visit Duration I have written some FlexUnit tests that run in my local Flash Player that exercise these resources -- they check that every label is represented in the metrics array, for example, so I know that the resource file is loaded when run locally. However, when I copy the module .swf file over to my server, the combo box to which the array is assigned is empty. I copy the .swf like so, if it matters: rsync -rlDv --inplace -T /tmp ~/projects/flex_reports/bin-debug/rankingFilter.swf HOSTNAME:WEBROOT/flashPath/ Why is this? I am not able to debug the remote module because our surrounding site sets up a lot of context and makes some database calls to determine which module to load. I'm hoping to get some pointers on why resource bundles might not show up. I'd understand it if the array was present with wrong labels, but the array is instead completely empty, which is pretty odd.

  • Why do I get two clicked or released signals when using a custom slot for a QPushButton ?

    - by Chris
    here's the main code at first I thought is was the message box but setting a label instead has the same effect. #include <time.h> #include "ui_mainwindow.h" #include <QMessageBox> class MainWindow : public QWidget, private Ui::MainWindow { Q_OBJECT public: MainWindow(QWidget *parent = 0); void makeSum(void); private: int r1; int r2; private slots: void on_pushButton_released(void); }; MainWindow::MainWindow(QWidget *parent) : QWidget(parent) { setupUi(this); } void MainWindow::on_pushButton_released(void) { bool ok; int a = lineEdit->text().toInt(&ok, 10); if (ok) { if (r1+r2==a) { QMessageBox::information( this, "Sums","Correct!" ); } else { QMessageBox::information( this, "Sums","Wrong!" ); } } else { QMessageBox::information( this, "Sums","You need to enter a number" ); } makeSum(); } void MainWindow::makeSum(void) { r1 = rand() % 10 + 1; r2 = rand() % 10 + 1; label->setText(QString::number(r1)); label_3->setText(QString::number(r2)); } int main(int argc, char *argv[]) { srand ( time(NULL) ); QApplication app(argc, argv); MainWindow mw; mw.makeSum(); mw.show(); return app.exec(); } #include "main.moc"

  • Using Python, what's the best way to create a set of files on disk for testing?

    - by Chris R
    I'm looking for a way to create a tree of test files to unit test a packaging tool. Basically, I want to create some common file system structures -- directories, nested directories, symlinks within the selected tree, symlinks outside the tree, &c. Ideally I want to do this with as little boilerplate as possible. Of course, I could hand-write the set of files I want to see, but I'm thinking that somebody has to have automated this for a test suite somewhere. Any suggestions?

  • VS Intellisense: can you hide extension methods?

    - by chris
    By default Visual Studio displays all members and its extension methods for a type in intellisense. Sometimes I would like to hide the extension methods to make it easier to find the member I am actually looking for (especially when using Linq). Is there a shortcut or another way to display only the members of a type in intellisense?

  • ScriptManager emits ScriptReferences after ClientScriptIncludes. Why?

    - by Chris F
    I have an application that uses a lot of javascript in a lot of different .js files. Each page can have any number and combination of different controls and each control can use a different set of js files. Instead of including all possible js files as <script src="xxx.js"> in the head of my master page, I thought I would reduce the amount of included files by getting each control to call ScriptManager.Scripts.Add(new ScriptReference("xxx.js")) - thus only the scripts that are actually needed by the page will be included. Well that bit works fine. But...the controls also use ScriptManager.RegisterClientScriptBlock fairly extensively too. (There are scenarios where the controls are inside update panels). I was disappointed to see that the ScriptManager emits the client script includes before the ScriptReferences. For example - see the test file and output at the end (this results in a JS error because $ is not defined). Am I being dumb or is this to be expected? I would have thought that a sensible thing for the ScriptManger to do would be to emit the ScriptReferences first and then the other stuff. Short of rolling my own ScriptManager like object to manage static JS file references, does anyone have any suggestions as to get the behaviour that I want from ScriptManager?? Thanks in advance.

  • How can I find the last value in a multidimensional array in php?

    - by Chris
    I am using a multidimensional array and I am trying to use php to find the last value of one of the arrays and based on that last number(value), add one more to it. Here is my multidimensional array structure: $_SESSION['cart']['add_complete'][1]['deck_id'] I am trying to create this structure, but instead of where it says 1 now, I want to find out what the last number in the add_complete array is and then add one more to it and put that in the place of the 1. How can I do that?

  • memory available to 64bit Fedora guest under 32bit XP host running virtualbox

    - by Chris Card
    I have successfully installed a 64 bit Fedora 11 guest os using VirtualBox on a host machine (AMD64) running 32 bit Windows XP . At the moment the host machine has 2 Gb ram installed and I've allocated 1 Gb to the guest, which all works well. The host machine can hold a maximum of 4 Gb ram, so I was wondering if it's worth buying an extra 2 Gb for it. I know that 32 bit Windows XP can't use all of the 4 Gb, but can the guest os use any of the ram that the host os can't use?

  • How to search SVN repository for a file when I'm not sure where I put it?

    - by Chris Thornton
    Co-worker is sure he checked in a file: foo_oustanding.dpr but isn't sure when/where (we have lots of "tools" and "utility" ancillary branches, lots of project branches, etc.. I need a way to search the entire repository for this file. I could check the whole source tree out to my HD, but that would take several hours. Is there a faster way? I tried the Repo Browser (Tortoise) and it didn't seem to have a search. I also thought about dumping the log, from the beginning of time. But that seemed silly. I have, at my disposal: Tortoise SVN 1.6 Subversion 1.5.6 running on Apache It runs on a Windows 2003 server. Remote Desktop access to the server, with admin rights. Thanks for any ideas.
