• Getting Google Chrome to Ignore IE Javascript

  - by swajak

  I'm creating a slideshow using javascript that fades images. Awhile back, I discovered that to change the opacity of an image, I have to use a different API, depending on whether the page is viewed in Firefox or IE. Firefox: img.style.opacity = [value 0 to 1]; IE: img.style.filter="progid:DXImageTransform.Microsoft.Alpha(opacity= [value 0 to 100] )"; So, currently, I use <script LANGUAGE="JScript"> for code that is meant for IE. This was suggested in the Mozilla docs. The problem: Chrome thinks my <script LANGUAGE="JScript"> code is valid, when it is not. How to make Chrome ignore the code inside <script LANGUAGE="JScript"> ? Or how to make my opacity code cross-browser?

• m2eclipse/svn project with packaging of pom

  - by wuntee

  I have a project with the following layout taac * taac-web * taac-backend-api * taac-scheduler all of this is checked into an SVN repository. When creating a new project in eclipse (originally) I checked out the root taac directory, and it gave me the option to select each of the sub-projects to create new eclipse projects for. I had a problem with svn and had to remove the projects from eclipse, and now when trying to check them out, i no longer get this option. If I select just the sub-projects, then their pom's are invalid (due to not having the parent pom).... Does anyone know how to get that option to select each separate project out?

• WPF component for 2D tree diagram

  - by pdm2011

  I'm looking for a well-documented, supported WPF component that provides an API for visualisation of 2D tree diagrams. Ideally something easy to use, customisable (i.e. supports various flavours of nodes and splines) and preferably with automated layout control. Tools that look good so far are GoXam (http://www.nwoods.com/components/silverlight-wpf/goxam-overview.htm) and yFiles WPF (http://www.yworks.com/en/products_yfileswpf_about.html). Just wondering if anyone has experience with either of these, or can recommend an alternative? Thanks!

• Get ExternalInterface definitions in Javascript

  - by Jamal Fanaian

  Is there a way to get a list of the exposed functions from a Flash object? For example, you could get a list of all methods in an object by executing: for (var i in object) { if (typeof object[i] == "function") { console.log(i); } } The only issue is that this won't expose any methods registered through the ExternalInterfaces API. I can try and see if the function exists (object['method']) and it tells me it is a function, but I would have to guess every existing method in this manner. NOTE: Obviously, I don't have access to the actionscript.

• AES acceleration for Java

  - by chris_l

  I want to encrypt/decrypt lots of small (2-10kB) pieces of data. The performance is ok for now: On a Core2Duo, I get about 90 MBytes/s AES256 (when using 2 threads). But I may need to improve that in the future - or at least reduce the impact on the CPU. Is it possible to use dedicated AES encryption hardware with Java (using JCE, or maybe a different API)? Would Java take advantage of special CPU features (SSE5?!), if I get a better CPU? Or are there faster JCE providers? (I tried SunJCE and BouncyCastle - no big difference.) Other possiblilities?

• Difficulty determining the file type of text database file

  - by Joseph Silvashy

  So the USDA has some weird database of general nutrition facts about food, and well naturally we're going to steal it for use in our app. But anyhow the format of the lines is like the following: ~01001~^~0100~^~Butter, salted~^~BUTTER,WITH SALT~^~~^~~^~Y~^~~^0^~~^6.38^4.27^8.79^3.87 ~01002~^~0100~^~Butter, whipped, with salt~^~BUTTER,WHIPPED,WITH SALT~^~~^~~^~Y~^~~^0^~~^6.38^4.27^8.79^3.87 ~01003~^~0100~^~Butter oil, anhydrous~^~BUTTER OIL,ANHYDROUS~^~~^~~^~Y~^~~^0^~~^6.38^4.27^8.79^3.87 ~01004~^~0100~^~Cheese, blue~^~CHEESE,BLUE~^~~^~~^~Y~^~~^0^~~^6.38^4.27^8.79^3.87 With those odd ~ and ^ separating the values, It also lacks a header row but thats ok, I can figure that out from the other stuff on their site: http://www.ars.usda.gov/Services/docs.htm?docid=8964 Any help would be great! If it matters we're making an open/free API with Ruby to query this data. Additionally I'm having a tough time posing this question so I've made it a community wiki so we can all pitch in!

• Creating Dynamic variables from json response

  - by c0mrade

  My JSON response looks like this : {"sample":[{"id":"2","name":"branch name"},{"id":"3","name":"branch name 2"}]} My function looks like this : function getJSONObjects(){ $.getJSON("http://localhost/api/branches", function(data){ $.each(data.sample, function(i,item){ var loc = "branch"; eval("var " + loc + item.id + "=123;"); alert(loc + item.id); }); }); } The idea is to create branch + id object so I can do something with it(create marker on a map), so I tried to assign it any value to see if this was working. I wanted both branch2 and branch3 to alert 123 so I have something to start with. But currently this alerts branch2 and branch3 instead of 123. I have little experience with creating dynamic variables/objects can someone tell me what I'm doing wrong or maybe another approach towards solving this?

• PUT parameters not working in python / google app engine

  - by magegu

  hi, i'm working on a simple RESTful webservice with python with the webapp framework on the google app engine.

• iOS Facebook SDK: FBRequestDelegate only works on AppDelegate??

  - by RMR

  Hi guys, I want to encapsulate all my Facebook interactions within a FacebookFacade class to keep things clean and tidy. I have an instance of the iOS SDK Facebook class within my FacebookFacade. My problem is that when I make a Graph API call within the facade, such as: [self.facebook requestWithGraphPath:@"me" andDelegate:self]; the only method of FBRequestDelegate that gets called is requestLoading: and nothing else. I have tried putting similar code in other places, like in controllers and other models, and there too not all of the FBRequestDelegate methods get called, only requestLoading:. In fact the only way I can get the other FBRequestDelegate methods to be called is to put all my Facebook logic in the AppDelegate and make my AppDelegate the FBRequestDelegate. Why is this the case? Am I missing something here? I definitely do not want to use the AppDelegate as my FBRequestDelegate as I don't want to confuse the purpose of the AppDelegate. Thanks.

• latin bases language segmentation gramatical rules

  - by pravin

  Hi folks, I am working on one feature i.e. to apply language segmentation rules ( grammatical ) for Latin based language ( English currently ). Currently I am in phase of breaking sentences of user input. e.g.: "I am working in language translation". "I have used Google MT API for this" In above example i will break above sentence by full stop (.) This is normal cases where I am breaking sentence on dot, but there are n number of characters for breaking sentence like ( . ! ? etc ). I have following SRX rules for segmentation. Here my question are :- 1) Is there any reference ? which I can use for resolving my language segmentation rules. 2) Or Is there any forums on language segmentation ? , so that i can discuss efficiently Please let me know if anybody know about this ? Thanks a lot.

• System.Interactive: Difference between Memoize() and MemoizeAll()?

  - by Joel Mueller

  In System.Interactive.dll (v1.0.2521.0) from Reactive Extensions, EnumerableEx has both a Memoize method and a MemoizeAll method. The API documentation is identical for both of them: Creates an enumerable that enumerates the original enumerable only once and caches its results. However, these methods are clearly not identical. If I use Memoize, my enumerable has values the first time I enumerate it, and seems to be empty the second time. If I use MemoizeAll then I get the behavior I would expect from the description of either method - I can enumerate the result as many times as I want and get the same results each time, but the source is only enumerated once. Can anyone tell me what the intended difference between these methods is? What is the use-case for Memoize? It seems like a fairly useless method with really confusing documentation.

• C# Using singleton instead of a global static instance

  - by Farstucker

  I ran into a problem today and a friend recommended I use a global static instance or more elegantly a singleton pattern. I spent a few hours reading about singletons but a few things still escape me. Background: What Im trying to accomplish is creating an instance of an API and use this one instance in all my classes (as opposed to making a new connection, etc). There seems to be about 100 ways of creating a singleton but with some help from yoda I found some thread safe examples. ..so given the following code: public sealed class Singleton { public static Singleton Instance { get; private set; } static Singleton() { Instance = new Singleton(); } } How/Where would you instantiate the this new class and how should it be called from a separate class? Thanks for your help.

• Where is the appropriate place to define inflector rules in CakePHP 1.3?

  - by Daniel Wright

  In CakePHP 1.2, custom inflector rules could be defined in a file app/config/inflections.php. This file was removed in CakePHP 1.3. Instead, the documentation prescribes using the Inflector::rules function to load custom inflections. There's adequate documentation of how to define the custom inflections themselves, but the documentation gives no context—where to use Inflector::rules. Should any custom inflections be defined in the bootstrap.php script? At the top of applicable corresponding controllers? Somewhere else? See also: Configuration: Inflections in the documentation Inflector::rules definition in the API documentation

• how can I send messages to/from a Websphere Message Broker from an embedded C client (no JVM)?

  - by queBurro

  What are my options for pubsubing (or point to point but pubsub is better) messages to and from an IBM message broker from an embedded headless C/C++ linux client that doesn't have a JVM? Ideally we want large file transfer (2GB once per day off of the client) encryption (SSL) reliable ('assured' delivery / QoS2, maybe QoS1 would do) The client in question currently only has exes and some bash scripts, I've been playing with MQTTv3 and RSMB, but for that I'd have to chomp the large files up (and reassemble back home) and I don't want to get into that if there's a transport that will do this for me? I've looked at MQTTv5 (but our client's got no JVM); JMS (no JVM) and XMS? which again looks like it gives me a C API but then needs the JVM to be installed on the client (or am I wrong?) any clues or hints would be appreciated, cheers

• Web services Authentication Jungle

  - by redben

  I have been doing some research lately about best approaches to authenticating web services calls (REST SOAP or whatever). But none of the Approaches convinced me... But i still can't a make a choise... Some talk about SSL and http basic authentication -login/password- which just seems weird for a machine (i mean having to assign a login/password to a machine, or is it not ?). Some others say API keys (seems like these scheme is more used for tracking and not realy for securing). Some say tokens (like session IDs) but shouldn't we stay stateless (especially if in REST style) ? In my use case, when a remote app is calling one of our web services, i have to authenticate the calling application obviously, and the call must - if applicable - tell me which user it impersonates so i can deal with authorization later. Any thoughts ?

  - by Surjya Narayana Padhi

  Hi Geeks, I developing a GUI in QT where I have to show the battery status icon. To get the system power status, I am using the windows API. But to show status anytime , do i need to use a thread to continuously read and display the power status? I am thinking of using event handler. But not sure how to implement. I am thinking that for just one status icon I will run a thread. Anybody has any better suggestion, please share.

• Whats the best solution for a database used in conjunction with Maps in Android?

  - by Andrew

  Could someone please point me in the right direction. My project involves a database where users enter their address and other info from my website. This database is then referenced in my android application to show the locations of these addresses in my database. I have yet to start and just came up with this idea. My question is, what would be the best method to create a database easily modified through my website (mySQL, php, etc), and also easily referenced easily through Android and the Google Maps API? I need some ideas on the languages I will need to use to create this database and website so I can go buy the necessary books to start reading up. Thanks so much

• j2ME setLocationListener()

  - by Jeff Catania

  I'm programming a GPS tracking system using the Motorola i335 running on Sprint's IDEN network. I'm using the javax.microedition.location api to find the GPS coordinates. To set up the updating, you use the [setLocationListener][1] method. I originally tried passing (listener,2,1,1). However there was too many invalid locations being received (where the GPS could not get the fix in the specified time), so I changed the parameters to (listener, 20, 20, 1). Now the system barely throws any invalid locations. My goal is to get the fastest number of updates that are realistic. Have any of you found a happy medium for parameters of this method?

• Copying a 14bit grayscale image (saved in long[]) to a pictureBox

  - by Itsik

  My camera gives me 14bit grayscale images, but the API's function returns a long* to the image data. (so i'm assuming 4 bytes for each pixel) My application is written in C++/CLI, and the pictureBox is of .NET type. I am currently using the BitmapData.LockBits() mechanism to gain pointer access to the image data, and using memcpy(bmpData.Scan0.ToPointer(), imageData, sizeof(long)*height*width) to copy the image data to the Bitmap. For now, the only PixelFormat that is working is 32bit RGB, and the image appears in shades of blue with contours. Trying to initialize the Bitmap as 16bppGrayscale isn't working. I would ideally want to cast the array from long to word and using a 16bit format (hoping the the 14bit data will be displayed properly) but I'm not sure if this works. Also, I don't want to iterate over the image data, so finding the min/max and then histogram stretching to [0..255] isnt an option for me (the display must be as efficient as possible) Thanks

• Best way to show a loading screen in an iPhone app?

  - by pkulak

  I'm building what is essentially a web app. Every piece of data has to be fetched from a web API. So, every UITableView that I show takes some amount of time to fill with data and I'm struggling to find a good way to show the user a loading screen. Right now I'm popping up an action sheet, but that just seems a bit wrong. Ideally, I'd popup up a blank view over the tableview with "Loading..." on it, then fade it away when the data comes in, but I can't think of a way to do that in 8 places in my app without massive code duplication.

• Read from POS Devices

  - by Garhwali Bhai

  Hi Experts, What would be the best design for a Java web based application to read Check or Credit Card from POS Devices which are configured/installed at client machine? The design which I have decided is: When cashier selects payment mode as 'Check' or 'Credit Card' open a pop-up. From pop-up, I am calling an Applet through JNLP which implements JPOS API to communicate with POS devices at client machine. When cashier swipes or inserts check, Applet class read them and send the information back to the pop-up window. Pop up window call the parent window, populate all the required field and close the pop-up.
