• Lightbox for embeddable JavaScript widget? Like Feedback tabs for UserVoice/GetSatisfaction

  - by Eliot Sykes

  There are so many lightboxes to choose from, I'm looking for a very lightweight one to use in an embedded javascript widget that would be used on a number of different web sites. This would work in a similar way to the GetSatisfaction/UserVoice feedback tab. Here are the requirements for the lightbox: Very small javascript download (animation not needed) Self contained, not dependent on any libraries such as jquery, etc. Works in major browsers Lightbox displays HTML content from a given URL Close button (like GetSatisfaction or UserVoice) Dims background Avoids javascript namespace conflicts (or can easily be made to avoid them) CSS styling of lightbox does not interfere with site styling Have you used an existing lightbox scripts for this same purpose with similar requirements? Did you roll your own? Insights welcome! Thanks, Eliot

• PHP code work on localhost but not webhotel ($_GET)

  - by Mestika

  Hi all, The following code works fine on my WAMP localhost server, but when I try to upload it, to my webhoste, it don't and I'm a bit confused about what's wrong. The code is: <?php if(isset($_GET['menu'])) { if($_GET['menu'] == 3) { echo "<!--Gallery Scripts-->\n"; echo gallery(); } } ?> The purpose is that if the URL is saying: index.php?menu=3 it will run the function "gallery()" which will load the gallery. I'm doing this "trick" several times to avoid the page to load all my JavaScript and function each time the page loads. Thanks Mestika

• Can Cython compile to an EXE?

  - by ThantiK

  I know what Cythons purpose is. It's to write compilable C extensions in a Python-like language in order to produce speedups in your code. What I would like to know (and can't seem to find using my google-fu) is if Cython can somehow compile into an executable format since it already seems to break python code down into C. I already use Py2Exe, which is just a packager, but am interested in using this to compile down to something that is a little harder to unpack (Anything packed using Py2EXE can basically just be extracted using 7zip which I do not want) It seems if this is not possible my next alternative would just be to compile all my code and load it as a module and then package that using py2exe at least getting most of my code into compiled form, right?

• Pool Billiard AI

  - by Sebi

  Im implementing a pool billiard game in Java and it all works fine. It is a multiplayer game, but nevertheless, it should also be possible to play it alone. For this purpose I'm trying to implement a simple KI. At the moment, the KI choose just randomly a direction and a random intensity of the impulse (don't know the correct english word for that). Of course this AI is very poor and unlikely to ever challenge a player. So i thought about improving the KI, but there are several hard to solve problems. First I thought of just choosing the nearest ball and to try to put it directly into the nearest hole. This isn't that bad, but if there other balls in the line between, it isn't really working anymore. Additionally this dosn't solve te problem of calculating the intensity of the impulse. So are there any general advice? Or any ideas? Best practices?

• Review Board workflow for Mercurial repository

  - by pachanga

  At my company we are trying to add code reviewing practices into our development process and for that purpose we decided to use Review Board. While Review Board should work out of the box for Subversion the workflow for Mercurial looks a little bit involved. Firstly it seems that only post reviewing(via post-review script) is supported for this type of repo. Secondly documentation is unclear whether post-review actually supports Mercurial(it only mentions git). Could you folks describe your workflow in detail please? Am I right in my thinking it should be something like this: Developer: clone master repo clone feature repo from local master repo hack-hack in feature repo commit into feature repo somehow run post-review from feature repo against parent master repo Reviewer: review diff if OK then pull to the master repo from the feature repo

• Erlang Supervisor Strategy For Restarting Connections to Downed Hosts

  - by derdewey

  I'm using erlang as a bridge between services and I was wondering what advice people had for handling downed connections? I'm taking input from local files and piping them out to AMQP and it's conceivable that the AMQP broker could go down. For that case I would want to keep retrying to connect to the AMQP server but I don't want to peg the CPU with those connections attempts. My inclination is to put a sleep into the reboot of the AMQP code. Wouldn't that 'hack' essentially circumvent the purpose of failing quickly and letting erlang handle it? More generally, should the erlang supervisor behavior be used for handling downed connections?

• DSP - How are frequency amplitudes modified using DFT?

  - by Trap

  I'm trying to implement a DFT-based equalizer (not FFT) for the sole purpose of learning. To check if it works I took an audio signal, analyzed it and then resynthesized it again with no modifications made to the frequency spectrum. So far so good. Now I tried to silence some frequency bands, just by setting their amplitudes to zero before resynthesis, but definitely it's not the way to go. What I get is a rather distorted signal. I'm using the so-called 'standard way of calculating the DFT' which is by correlation. I first tried to modify the real part amplitudes only, then modifying both the real and imaginary part amplitudes. I also tried to convert the DFT output to polar notation, then modifying the magnitude and convert back to rectangular notation, but none of this is working. Can someone show me what I'm doing wrong? I tried to find info on this subject in the internet but couldn't find any. Thanks in advance.

• ImageMagick vs. Cairo on Vector Graphics rasterization

  - by Sherwood Hu

  I am working on a project that needs rasterizing of drawings into image files. I have already got it work using GDI+. Wanting to create a portable solution, I am also looking into other solutions and found two - cairo and imagemagick. I am new to both, but it seems that ImageMagick can do almost all the stuff - drawing lines, arcs, circles, text etc.. plus many bitmap manipulation. However, Cairo is mentioned as competitor to GDI+ in web sites. ImageMagick is never mentioned for this purpose. I do not have time to invest on both libraries. I need to decide which one is worthy. I prefer to ImageMagick, as it seems much more powerful. What's your opinion on the two graphic libs?

• Changing Render Kits in Browser

  - by John

  I'm working on a project to develop a cross-browser testing web app. Simply put, I'm tired of having to maintain multiple browsers on the same system and IE in VMware solely for the purpose of testing. Does anyone know if there is any way to change the render kit programmatically? For example, if I insert a URL, I would be able to load the URL and switch the browser render within a frame of some assortment. I am experienced with PHP, JS, and RoR if there is a solution using any of those. Thank you! John

• What WPF frameworks should I use?

  - by joebeazelman

  I'm a newbie to WPF and I'm developing a brand new windows desktop application and I would like your opinion on what WPF framework I should use. I know this question has been asked before, but the last question was asked at least several months ago. A lot has changed since then. Right now, I'm using MVVM Light which is more of a library than an actual framework, as the name suggests. I’m looking for something more comprehensive. I prefer a framework that I can use on future WPF projects. Consequently, it should be general purpose and productive. Any insights or suggestions?

• How can I measure the quality of a fax file?

  - by debita

  Hi! I'm trying to make a tool that can measure the quality of a fax file, comparing the received one with the one sent. I tried Phase_Correlation software, in order to see if the images are similar... but it's not enough. My purpose is to evaluate if the fax is legible after the transmission. Any ideas? Is there any way of comparing two tiffs? pdfs? or image files? Thanks a lot

• 'Programming by Coincidence' Excercise: Java File Writer

  - by Tapas

  I just read the article Programming by Coincidence. At the end of the page there are excercises. A few code fragments that are cases of "programming by coincidence". But I cant figure out the error in this piece: This code comes from a general-purpose Java tracing suite. The function writes a string to a log file. It passes its unit test, but fails when one of the Web developers uses it. What coincidence does it rely on? public static void debug(String s) throws IOException { FileWriter fw = new FileWriter("debug.log", true); fw.write(s); fw.flush(); fw.close(); } What is wrong about this?

• Dynamically creating controls in MFC (Collection question)

  - by ProgramWriter

  Hello all, I have some custom control inside of which i should create radiobuttons or checkboxes. The count of child controls is available only at runtime (it loads some file from which it gets this count). So i need to create variable number of controls. Which collection i should use for this purpose? Solution 1: simply use std::vector (or CArray) - not suitable because i want use MFC (CButton). Of course i can Attach() and later Detach() handle to window each time i need this window, but it will give big overhead. Solution 2: use std::vector or CArray or CList or... In this case i take care about making 'new' and appropriate 'delete' when control is unneeded. I am forgetful :) MFC handle map contains pointer to CButton and i can't use simple CArray, because it will move my objects each time when his size will grow. ... and the question is: Which collection i should use for containing variable count of MFC control classes?

• Issues with dynamically loading modules in code with Silverlight/Prism

  - by Greg Bailey

  In my Bootstrapper.cs in GetModuleCatalog, I need to specify the Module types using the typeof(ModuleType). In the example below I'm trying to load the Contact module on demand, but in order to get it into my module catalog, I need to have a reference to it in the project that holds my Bootstrapper. When I add a reference to Contact, then the Contact.dll gets added to the initial xap file, which defeats the purpose of loading the module dynamically. Am I missing something? Do you have to load the module catalog from a file to make this work? var catalog = new ModuleCatalog(); catalog.AddModule(typeof(Core)); catalog.AddModule(typeof(Contact), InitializationMode.OnDemand);

• problem with Chrome form handling: input onfocus="this.select()"

  - by binaryorganic

  I'm using the following HTML code to autoselect some text in a form field when a user clicks on the field: input onfocus="this.select()" type="text" value="Search" This works fine in Firefox and Internet Explorer (the purpose being to use the default text to describe the field to the user, but highlight it so that on click they can just start typing), but I'm having trouble getting it to work in Chrome. When I click the form field in Chrome the text is highlighted for just a split second and then the cursor jumps to the end of the default text and the highlighting goes away. Any ideas on how to get this working in Chrome as well?

• Why can you reference an imported module using the importing module in python

  - by noam

  I am trying to understand why any import can be referenced using the importing module, e.g #module master.py import slave and then >>>import master >>>print master.slave gives <module 'slave' from 'C:\Documents and Settings....'> What is the purpose of the feature? I can see how it can be helpful in a package's __init__.py file, but nothing else. Is it a side effect of the fact that every import is added to the module's namespace and that the module's namespace is visible from the outside? If so, why didn't they make an exception with data imported from other modules (e.g don't show it as part of the module's namespace for other modules)?

• PHP gallery, thumbnail listing

  - by Benjamin

  Hi everyone, I am planning a dynamic PHP photo gallery and having difficulty deciding on the best way to display the thumbnails after they have been retrieved via MySQL. I considered using an inline unordered list but this resulted in the thumbs being stacked one on top of the other (touching). Also tried a table but not sure how I would start the next row after x number of thumbnails. Any suggestions on page layout for this purpose? I will be using Lightbox to cycle through the photos themselves, that isn't the issue. Also, would a while() loop be best for fetching the list of thumbs and inserting the appropriate HTML? Thanks! -Ben

• Has anyone got a simple step by step Mozilla plugin tutorial.

  - by s1mm0t

  I'm trying to create a Mozilla browser plugin for the sole purpose of detecting with javascript whether or not an application that I have written is installed. This was inspired by another stackoverflow question and answer on a similar subject. All I want really is a HelloWorld type example as what I need to write will be even simpler than that. There is a lot of information on the Mozilla website, but as a plugin noob and a C++ novice I'm experiencing information overload. I just need a step by step "this is how to create your first simple plugin". I have already written the IE equivalent by following this ATL tutorial. This is the kind of level of guide that I would ideally like to find. Please note, this is specifically about Mozilla plugins and not extensions - Googling this subject brings up a lot of information about extensions in addition to plugins.

• Objective-C syntax

  - by mebFace

  I've been studying objective-c for a few days now. I keep coming across these two structures: NSString * somestring (NSString *) somestring I understand the first simply sets a pointer to an NSString object, but what does the second construct do, and when should I use it? What's the deal with the asterix marks? Sorry if this question doesn't make any sense, I am completely new to this language, and haven't even reached the level of asking proper questions. Main purpose -- I'm trying to decipher this method: -(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger) row forComponent: (NSInteger)component *Also, the classes I chose don't matter. *

• TFS Database Edition doesn't seem to Script Logins

  - by Jaco Pretorius

  I'm trying to put all our databases in TFS. For this purpose we're using TFS Database edition - I've seen some of the other Dev teams use it and it seems pretty good. Problem is that it doesn't seem to script the logins - the users are linked to logins which now break due to the logins not being scripted. As far as I can tell I can't get around this - the Schemas need the users which in turn need the logins. How do you handle logins in TFS Database Projects? This is SQL Server 2008.

• How to return a dynamic value from a Mocha mock in Ruby

  - by Vivek

  The gist of my problem is as follows:- I'm writing a Mocha mock in Ruby for the method represented as "post_to_embassy" below. It is not really our concern, for the purpose of describing the problem, what the actual method does. But I need the mock to return a dynamic value. The proc '&prc' below is executing rightly in place of the actual method. But the "with" method in Mocha only allows for boolean values to be returned. So the code below outputs nil. I need it to output the value being passed through orderInfoXml. Does anyone know of an alternate method I can use? require 'rubygems' require 'mocha' include Mocha::API class EmbassyInterface def post_to_embassy(xml) puts "This is from the original class:-" puts xml return xml end end orderInfoXml = "I am THE XML" mock = EmbassyInterface.new prc = Proc.new do |orderXml| puts "This is from the mocked proc:-" puts orderXml orderXml end mock.stubs(:post_to_embassy).with(&prc) mock_result = mock.post_to_embassy(orderInfoXml) p mock_result #p prc.call("asd") output:- This is from the mocked proc:- I am THE XML nil

• ASP.NET: Enumerating header elements from codebehind

  - by JamesBrownIsDead

  On Page_Load() in the codebehind, I'd like to enumerate all the <link> tags. The purpose being I want want to add a <link> to a CSS file if it isn't specified in the Page's markup. How can I do this? I'm thinking I should be able to use LINQ on the collection of elements in the header, no? Here's my pseudocode: var pageAlreadyContainsCssLink = false; foreach(var control in this.Header.Controls) { if (control.TagName == "link" && control.Attributes["href"] == "my_css_file.css") { pageAlreadyContainsCssLink = true; break; } } if (pageAlreadyContainsCssLink) { // Don't add <link> element return; } // Add the <link> to the CSS this.AddCssLink(...);

  - by vikramjb

  I am working on a simple java code to extract all calendar entries for a given date. I know it possible using Domingo but I would like to use only Notes.jar for this purpose. It is possible for me to create a session based on a given credentials and get the calendar object.

Anybody have any idea or links on this ?

• Bind a users role to dropdown?

  - by Dynde

  Hi... I'm trying to bind a selected user's role to a dropdown-list. The purpose of this is to be able to change said user's role. I'm attempting this inside a formview hooked up to a linqdatasource which contains a row from the aspnet_User table. The dropdown list is hooked up to a linqdatasource of all the roles in the aspnet_Roles table (with DataValueField="RoleID", DataTextField="RoleName"). I figured it would be possible with something like: SelectedValue='<%# Bind("aspnet_UsersInRole[0].aspnet_Role.RoleID") %>' But this throws a parser exception, about the bind call not being correctly formatted. The roles are there, they show up when I remove the "SelectedValue" Can anyone point me in the right direction?
