• How to convert the output of an artificial neural network into probabilities?

  - by Mathieu Pagé

  I've read about neural network a little while ago and I understand how an ANN (especially a multilayer perceptron that learns via backpropagation) can learn to classify an event as true or false. I think there are two ways : 1) You get one output neuron. It it's value is 0.5 the events is likely true, if it's value is <=0.5 the event is likely to be false. 2) You get two output neurons, if the value of the first is than the value of the second the event is likely true and vice versa. In these case, the ANN tells you if an event is likely true or likely false. It does not tell how likely it is. Is there a way to convert this value to some odds or to directly get odds out of the ANN. I'd like to get an output like "The event has a 84% probability to be true"

• Microsoft sublanguage string to locale identifier

  - by Jacob

  I can't seem to find a way to convert, or find, a local identifier from a sublanguage string. This site shows the mappings: http://msdn.microsoft.com/en-us/library/dd318693(v=VS.85).aspx I want the user to enter a sublanguage string, such as "France (FR)" and to get the local identifier from this, which in this case would be 0x0484. Or the other way around, if a user enters 0x0480 then to return French (FR). Has anyone encountered this problem before and can point me in the right direction? Otherwise I'm going to be writing a few mapping statements to hard code it and maintain future releases if anything changes. BTW, I'm coding in C++ for Windows platform. Cheers

• How should I implement items that are normalized in the Database, in Object Oriented Design?

  - by Jonas

  How should I implement items that are normalized in the Database, in Object Oriented classes? In the database I have a big table of items and a smaller of groups. Each item belong to one group. This is how my database design look like: +----------------------------------------+ | Inventory | +----+------+-------+----------+---------+ | Id | Name | Price | Quantity | GroupId | +----+------+-------+----------+---------+ | 43 | Box | 34.00 | 456 | 4 | | 56 | Ball | 56.50 | 3 | 6 | | 66 | Tin | 23.00 | 14 | 4 | +----+------+-------+----------+---------+ Totally 3000 lines +----------------------+ | Groups | +---------+------+-----+ | GroupId | Name | VAT | +---------+------+-----+ | 4 | Mini | 0.2 | | 6 | Big | 0.3 | +---------+------+-----+ Totally 10 lines I will use the OOP classes in a GUI, where the user can edit Items and Groups in the inventory. It should also be easy to do calculations with a bunch of items. The group information like VAT are needed for the calculations. I will write an Item class, but do I need a Group class? and if I need it, should I keep them in a global location or how do I access it when I need it for Item-calculations? Is there any design pattern for this case?

• Accept-Encoding headers being sent by browser but not received by server

  - by Daniel Jacobs

  I have been trying to debug this for weeks. All of the browsers on all of the clients on my home network are sending 'Accept-Encoding: gzip,deflate'. However, that header is somehow, somewhere being dropped before the request makes it to a web server. For example, http://www.whatsmyip.org/http_compression/ says 'No, your browser is not requesting compressed content'. I've used Fiddler to make sure that all of my browsers are indeed sending the header. I've swapped out my router. I've turned off all anti-virus software. Brighthouse/Roadrunner (the local cable ISP) says they are not doing any filtering (and I can't see why they would in this case). Any suggestions would be most welcome!

• How does one modify the thread scheduling behavior when using Threading Building Blocks (TBB)?

  - by J Teller

  Does anyone know how to modify the thread scheduling (specifically affinity) when using TBB? Doing a high level analysis on a simple parallel-for application, it seems like TBB is specifying the underlying threads' affinity in a way that reduces performance. Specifically, the cores I'm running on have hyper-threading enabled, and it looks like TBB is affinitizing threads to the same core even if there is a different core left completely unloaded. FWIW, I realize it's likely that TBB is doing the "right thing" and that changing the threads' affinity will only reduce performance. I'd just like to experiment with it to see if that's really the case.

• Override bits of a CSS class while inline?

  - by larryq

  I have an html img that is being styled by a CSS class. I would like to override the width and height values used in that class under some circumstances. I'm building this img tag using something called a TagBuilder class, provided by Microsoft for the .Net system, which allows developers to assign attributes to an html element. In this case a CSS class has been assigned to the img tag, and I can assign width and height attributes individually, but they're not taking precedence over the values set in the CSS class. My tag looks like this currently: <img alt="my link" class="static" height="240" id="StaticImage" src="http://imageserver.com/myImage.jpg" width="240"> The static CSS class has width and height values of 300 each, and as you can see I'm trying to override them with 240. It's not working in this instance but can I do it without a second CSS class?

• What is the best data structure and algorithm for comparing a list of strings?

  - by Chiraag E Sehar

  I want to find the longest possible sequence of words that match the following rules: Each word can be used at most once All words are Strings Two strings sa and sb can be concatenated if the LAST two characters of sa matches the first two characters of sb. In the case of concatenation, it is performed by overlapping those characters. For example: sa = "torino" sb = "novara" sa concat sb = "torinovara" For example, I have the following input file, "input.txt": novara torino vercelli ravenna napoli liverno messania noviligure roma And, the output of the above file according to the above rules should be: torino novara ravenna napoli livorno noviligure since the longest possible concatenation is: torinovaravennapolivornovilligure Can anyone please help me out with this? What would be the best data structure for this?

• HTML5 Doctype Support

  - by Metropolis

  Hey Everyone, For a long time I have been using XHTML1.1 because I thought I was cool (yeah right). However, today I read Ian Hickson's Article about how everyone uses the wrong MIME type with XHTML and it opened my eyes a lot. I happen to be one of those people who are serving XHTML with text/html MIME, because like a lot of people, W3C says its "ok" to serve it this way. At the top of that article he says that "now" he would serve it using the HTML5 doctype (!DOCTYPE HTML). What are your thoughts about doing this? If I did not use unsupported functionality, would it be ok? What would the MIME type be in this case? Thanks for any help, Metropolis

• ActionScript: Determine wether superclass implements a particular interface?

  - by David Wolever

  Is there any non-hacky way to determine wether a class' superclass implements a particular interface? For example, assume I've got: class A extends EventDispatcher implements StuffHolder { private var myStuff = someKindOfStuff; public function getStuff():Array { if (super is StuffHolder) // <<< this doesn't work return super['getStuff']().concat([myStuf]); return [myStuff]; } class B extends A { private var myStuff = anotherKindOfStuff; } How could I perform that super is StuffHolder test in a way that, well, works? In this case, it always returns true.

• NSUserDefaults and default language used for I18N

  - by fedmest

  I have searched around a lot for this and found some answers that sounded quite like what I wanted but never worked. I simply need to have my iPhone app load NIBs and Localizable.strings that I decide (through user selection) rather than the ones that are established through the global iPhone/iPad settings. General consensus seems to be that this line [[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObject:@"ro"] forKey:@"AppleLanguages"]; would do the trick (in this specific case, load the NIBs and Localizable.strings in ro.lproj) but I have not had such luck. It keeps on looking for the files in en.lproj or whatever language I chose in the Settings app. I have then tried adding this line [[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObject:@"ro_RO"] forKey:@"AppleLocale"]; and to my great surprise, it worked! ...only once :-( then back to the same issue. Has anyone got any idea how to solve this issue? The aforementioned code was added at the very start of applicationDidFinishLaunching, which is before any NIBs or strings files should be loaded.

• Deploying my flex application

  - by Vatsala

  Hi, I am doing some trial testing awith Amazon ec2 boxes, deploying flex apps running on top of restlet powered webservices. I have this problem - Everytime i deploy the app to the cloud, I'm having to hardcode the IP address of the server into the ActionScript/MXML files (http://72.93.48.39:8080/xxx/abc/) and for certain reasons, i am forced to choose a different IP everytime. and i think its really not the right way to deploy the application. I would like to know what other people do in such scenarios? On thinking about it, i thought i could make it pickup values from the HTMLVars of the HTML wrapper. but that again has to be edited everytime again and again. will it be possible to be able to supply these values : server's ip address, server's port number(in case its not 8080 on some machine) at build time? if so can anyone give me a barbones sample build.xml just as an example?

• Clear Select options when selecting one field while using multiple forms on same page

  - by Nizam

  Hi all, I have a situation where the second select list option is generated from the first select list selected option. Like when we select Country corresponding states are generated in next select list. In my case I am having multiple forms on single page which are same. Can anyone let me know how to implement it on multiple forms. I tried the following code but it didn't work $(".country").change(function(){ $.get("sample.php?val=" + $(this).val(), function(data){ $(this).parent().next().children('.state').children('option').remove(); $(this).parent().next().children('.state').append(data); }); Waiting for your support thanks in advance

• How to replace the nth column/field in a comma-separated string using sed/awk?

  - by Peter Meier

  assume I have a string "1,2,3,4" Now I want to replace, e.g. the 3rd field of the string by some different value. "1,2,NEW,4" I managed to do this with the following command: echo "1,2,3,4" | awk -F, -v OFS=, '{$3="NEW"; print }' Now the index for the column to be replaced should be passed as a variable. So in this case index=3 How can I pass this to awk? Because this won't work: echo "1,2,3,4" | awk -F, -v OFS=, '{$index="NEW"; print }' echo "1,2,3,4" | awk -F, -v OFS=, '{$($index)="NEW"; print }' echo "1,2,3,4" | awk -F, -v OFS=, '{\$$index="NEW"; print }' Thanks for your help!

• Given a Member Access lambda expression, convert it to a specific string representation with full ac

  - by Nathan

  Given an Expression<Func<T, object>> (e.g. x = x.Prop1.SubProp), I want to create a string "Prop1.SubProp" for as deep as necessary. In the case of a single access (e.g. x = x.Prop1), I can easily do this with: MemberExpression body = (expression.Body.NodeType == ExpressionType.Convert) ? (MemberExpression)((UnaryExpression)expression.Body).Operand : (MemberExpression)expression.Body; return body.Member.Name; However, if there is deeper nesting, e.g. x = x.Prop1.SubProp1, this only gets the most deeply nested name, e.g. "SubProp1" instead of "Prop1.SubProp1" Is there anyway to access the full property path of a lambda expression?

• Reading files from an embedded ZIP archive

  - by aix

  I have a ZIP archive that's embedded inside a larger file. I know the archive's starting offset within the larger file and its length. Are there any Java libraries that would enable me to directly read the files contained within the archive? I am thinking along the lines of ZipFile.getInputStream(). Unfortunately, ZipFile doesn't work for this use case since its constructors require a standalone ZIP file. For performance reasons, I cannot copy the ZIP achive into a separate file before opening it. edit: Just to be clear, I do have random access to the file.

• How to show a client-side message with Java JSF/Tobago?

  - by Marcus

  I have a web application created with JSF and Tobago. The user types some date into a sheet and clicks a button (all within one sheet-row). Now my java class checks whether the data is correct or not. In case there are some problems, I would like to show up something like a messagebox containing the errormessage. I cannot use something like JDialog, since this would happen only server side. Every user independently of his location needs to get the message. I thought about setting the error information into a databean and having my jsp show up the message after reloading. But how can I achieve this? Is there something like a tag which can be used for this? Or can I use the "confirmation" facet for this? But how would I start it without having the user to do something? Thanks in advance!

• asp.mvc model design

  - by Radu D

  Hi, I am pretty new to MVC and I am looking for a way to design my models. I have the MVC web site project and another class library that takes care of data access and constructing the business objects. If I have in that assembly a class named Project that is a business object and I need to display all projects in a view ... should I make another model class Project? In this case the classes will be identical. Do I gain something from doing a new model class? I don't like having in views references to objects from another dll ... but i don't like duplicating the code neither. Did you encounter the same problem?

• Generic extension method returning IEnumerable<T> without using reflection

  - by roosteronacid

  Consider this snippet of code: public static class MatchCollectionExtensions { public static IEnumerable<T> AsEnumerable<T>(this MatchCollection mc) { return new T[mc.Count]; } } And this class: public class Ingredient { public String Name { get; set; } } Is there any way to magically transform a MatchCollection object to a collection of Ingredient? The use-case would look something like this: var matches = new Regex("([a-z])+,?").Matches("tomato,potato,carrot"); var ingredients = matches.AsEnumerable<Ingredient>();

• authentication in PHP ?

  - by user296516

  Hi guys, I need to make an authentication script in php. I have already made a login.php page, where the user can enter his unsername/password and it gets checked against a database. If the unsername/password are correct, the user should be forwarded to members.php page together with a $_SERVER['username'] variable. What is the command in PHP to go to another webpage, in this case members.php ? in pseudocode I see it like this: if ( unsername/password are OK ) { $_SERVER['username'] = $username; goto(members.php); } Thanks!

• What programming language is used to design google algorithm?

  - by AKN

  It is known that google has best searching & indexing algorithm. The also have good relevancy. They are also quicker in getting down the latest results. All that's fine. What programming language (c, c++, java, etc...) & database (oracle, MySQL, etc...) they have used in achieving this. Since they have to manipulate with volume of data quickly and effectively. Though I'm not looking for their indepth architecture (if in case violates their company policies) an overview of all such things could be useful. Anybody please add you valuable suggestions and insight on this?

• MySQL Query: Winning Auction Bid

  - by mabwi

  I have a small Bidding system that I'm using for a fantasy auction draft. I'm trying to use the below query to pull up the max bids on each player. However, it's not actually giving me the max bid, it's just giving me the first one entered in to the database. SELECT Bid.id FROM bids AS Bid WHERE Bid.active =1 GROUP BY player_id HAVING MAX( Bid.amount ) Here's the Bid table layout, in case it helps: CREATE TABLE IF NOT EXISTS `bids` ( `id` int(10) NOT NULL AUTO_INCREMENT, `user_id` int(10) NOT NULL, `player_id` int(10) NOT NULL, `amount` int(6) NOT NULL, `timestamp` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP, `winning_bid` int(1) NOT NULL DEFAULT '0', `active` int(1) NOT NULL DEFAULT '1', PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 ;

• Bypassing Windows Copy design

  - by Scott S

  I have been trying to figure out a way to streamline copying files from one drive (network or external in my case) to my main system drives. Short of creating a program that I will have to activate each time then choosing all the info in it, I have no really good design to bypass it. I have been wondering if there was a way to intercept a straight-forward windows copy with a program to do it my way. The basic design would be that upon grabbing the copy (actually for this to be efficient, a group of different copies), the program would organize all the separate copies into a single stream of copies. I've been wanting to do this as recently I have been needing to make backups of a lot of data and move it a lot as all my drives seem to be failing the past few months.

• Is there a technical way to speed up a general program above current PC speed limit?

  - by Maksee

  Let's imagine I developed a Windows console application implementing some algorithm calculating something. Let's say it doesn't use any threads, just straightforward linear approach with ifs, loops and so on. Is there any technical way to make if run it 100x times faster than on the most advanced current PC? For example one of the way would be to run it on a super computer that emulates i386 faster than any of the existing PCs. But in this case the question what computer and does it really have ability to emulate Windows. In other words, is there real examples of such approach? Although in general it looks useless, but if there is a way, one could develop some program on his general home computer and pay for running it much faster on some other hardware. I suppose that this question could be asked on superuser.com, but since there are possible specific with such things as assembler instructions or threads, I thought that stackoverflow.com is better
