• Code golf: Reverse Polish notation (postfix) evaluator

  - by Dario

  After having had code-golf contests on ordinary mathematical expressions, I just thought it would also be quite interesting how short an evaluation function for postfix notation (RPN) can be. Examples for RPN: 1 2 + == 3 1 2 + 3 * == 9 0 1 2 3 + + - 2 6 * + 3 / 1 - == 1 3 2 / 2.0 + == 3.5 To make things shorter, only +, -, * and /, all just in their binary version, must be supported. Operators/Operands are delimited by one space, divsions by zero don't have to be handled. The resulting code should be a function that takes the postfix string as input and returns the resulting number.

• Using glRotate and glTranslate with collision detection.

  - by Cetra

  Hey guys, Say I use glRotate to translate the current view based on some arbitrary user input (i.e, if key left is pressed then rtri+=2.5f) glRotatef(rtri,0.0f,1.0f,0.0f); Then I draw the triangle in the rotated position: glBegin(GL_TRIANGLES); // Drawing Using Triangles glVertex3f( 0.0f, 1.0f, 0.0f); // Top glVertex3f(-1.0f,-1.0f, 0.0f); // Bottom Left glVertex3f( 1.0f,-1.0f, 0.0f); // Bottom Right glEnd(); // Finished Drawing The Triangle How do I get the resulting translated vertexes for use in collision detection? Or will I have to manually apply the transform myself and thus doubling up the work? The reason I ask is that I wouldn't mind implementing display lists.

• Fibonacci sequence subroutine returning one digit too high...PERL

  - by beProactive

  #!/usr/bin/perl -w use strict; sub fib { my($num) = @_; #give $num to input array return(1) if ($num<=1); #termination condition return($num = &fib($num-1) + &fib($num-2)); #should return sum of first "n" terms in the fibonacci sequence } print &fib(7)."\n"; #should output 20 This subroutine should be outputting a summation of the first "x" amount of terms, as specified by the argument to the sub. However, it's one too high. Does this have something to do with the recursion? Thanks.

• What are some of best Javascript memory detecting tools?

  - by Philip Fourie

  Our team is faced with slow but serious Javascript memory leak. We have read up on the normal causes for memory leaks in Javascript (eg. closures and circular references). We tried to avoid those pitfalls in the code but it likely we still have unknown mistakes left in our code. I started my search for available tools but would like input from people with actual experience with these tools. Some of the tools I found so far (but have no idea how good and useful they would be for our problem): Sieve Drip JavaScript Memory Leak Detector Our search is not limited to free tools, it will be a bonus, but more importantly something that will get the job done. We do the following in our Javascript code: AJAX calls to a .NET WCF back-end that send back JSON data Manipulate the DOM Keep a fairly sized object model in the Javascript to store current state

• Calling https process from ASP Net

  - by David M

  I have an ASP NET web server application that calls another process running on the same box that creates a pdf file and returns it. The second process requires a secure connection via SSL. The second process has issued my ASP NET application with a digital certificate but I still cannot authenticate, getting a 403 error. The code is a little hard to show but here's a simplified method ... X509Certificate cert = X509Certificate.CreateFromCertFile("path\to\cert.cer"); string URL = "https://urltoservice?params=value"; HttpWebRequest req = HttpWebRequest.Create(URL) as HttpWebRequest; req.ClientCertificates.Add(cert); req.Credentials = CredentialCache.DefaultCredentials; req.PreAuthenticate = true; /// error happens here WebResponse resp = req.GetResponse(); Stream input = resp.GetResponseStream(); The error text is "The remote server returned an error: (403) Forbidden." Any pointers are welcome.

• Adding a SVN repository in Eclipse

  - by Baltimark

  I'm trying to add an svn repository to eclipse. I've installed subclipse, and it seems to be working fine. But, when I try to "add a new SVN repository", I input this, for example: http://svn.python.org/projects/peps/trunk I get this: Error validating location: "org.tigris.subversion.javahl.ClientException: RA layer request failed svn: OPTIONS of 'http://svn.python.org/projects/peps/trunk': could not connect to server (http://svn.python.org) " Keep location anyway? I know that my eclipse can connect to the 'net because I downloaded subclipse earlier (I had to change my proxy settings). I get a similar message for other SVN locations I've tried to add. Anyone have any solutions?

• Stored Procedure to create Insert statements in MySql ??

  - by karthik

  I need a storedprocedure to get the records of a Table and return the value as Insert Statements for the selected records. For Instance, The stored procedure should have three Input parameters... 1- Table Name 2- Column Name 3- Column Value If 1- Table Name = "EMP" 2- Column Name = "EMPID" 3- Column Value = "15" Then the output should be, select all the values of EMP where EMPID is 15 Once the values are selected for above condition, the stored procedure must return the script for inserting the selected values. The purpose of this is to take backup of selected values. when the SP returns a value {Insert statements}, c# will just write them to a .sql file. I have no idea about writing this SP, any samples of code is appreicated. Thanks..

• How can I create a web based administration interface.

  - by The HCD

  Hi all, I'm planning to create a simple web based interface that stores administration input in json format (for use later by an applicaiton running on the same host) example json output is here: http://www.json.org/example.html The content would be user contacts (email, name, phone number, photo etc..) There would need to be a conf file per logged in user. and an administrator user for viewing all config files in his group. I'm wondering what technology is best to create this framework. I could do it via servlets etc.. however, there may be something simpler.. Thanks to all for your replies in advance.

• RSA Factorization problem

  - by dada

  At class we found this programming problem, and currently, we have no idea how to solve it. The positive integer n is given. It is known that n = p * q, where p and q are primes, p<=q and |q-k*p|<10^5 for some given positive integer k. You must find p and q. Input: 35 1 121 1 1000730021 9 Output: 5 * 7 11 * 11 10007 * 100003 It's not a homework, we are just trying to solve some interesting problems. If you have some ideas, please post them here so we can try something, thanks.

• How to Use .NET Assembly from Legacy SQL Server 2000 DTS

  - by shyneman

  Hi All, I have a .NET assembly that needs to be called from a DTS package. There are two options I am considering to get this to work: 1) write a COM-callable wrapper for the .NET assembly and have the VBScript create the COM object to use 2) write a .NET command-line exe that uses that .NET assembly and have the VBScript execute that exe Can anybody comment on the pros/cons of either approach and which is the better way of doing this? If there are other solutions, I'd love to hear them too. Thanks a lot for any input.

• Sorting an arraylist in Java language

  - by Computeristic

  Hi, I have an arraylist set up. I have input instuctions set up too, so that the user can enter one string, then one integer, then one string (the first name, the age, and the last name). I need to sort the arraylist by the last name. The code I have entered so far is all under the main method:- public static void main(String[] args) { Name Name[] = new Name[50]; int count = 0; for (int i=0; i<50; i++) NewName[i] = new Name(); //ADD NEW TO ARRAYLIST NAME String FName = JOptionPane.showInputDialog("first name"); int age = Integer.parseInt(JOptionPane.showInputDialog("age")); String LName = JOptionPane.showInputDialog("last name"); NewName[count] = new Name(FName, age, LName); count = count++; } //ITEMS SORT BY LAST NAME //CODE FOR SORT GOES HERE

• Reset form with jQuery

  - by da5id

  I have a form with a standard reset button coded thusly: <input type="reset" class="button standard" value="Clear" /> Trouble is, said form is of the multi-stage sort, so if a user fills out a stage & then returns later, the 'remembered' values for the various fields won't reset when the Clear button is clicked. I'm thinking that attaching a jQuery function to loop over all the fields and clear them 'manually' would do the trick. I'm already using jQuery within the form, but am only just getting up to speed & so am not sure how to go about this, other than individually referencing each field by ID, which doesn't seem very efficient. TIA for any help.

• SATA hard disk for laptop on Desktop PC

  - by Lawliet

  I know that this forum is for programming-related questions only, but I'm having this dilemma so here I go. Can I connect a laptop SATA hard disk to Desktop PC? Do I have to use some adapters or I can just plug in SATA power connector and SATA data cable like my Desktop hard disk is connected? I noticed that both laptop and desktop SATA disks use same connectors, but I'm afraid that I might fry my laptop hard disk because the SATA connector has both 12V and 5V voltage (given the fact that laptop hard disks has input voltage of 5V) Thanks in advance

• Question about a http form GET method, using query arguments

  - by Lasse V. Karlsen

  I am looking at a bug in WebSVN where when I get into a file log and click on compare, it looses the repository name as part of the request. The details are unimportant. However, I've tracked down the bug to a http form that looks like this: <form method="get" action="comp.php?repname=Binaries&amp;" id="compare"> .... <input type="hidden" name="KEY" value="VALUE"> Is this supposed to work? Will both the "repname" argument, specified as part of the URL, and the hidden value be sent? It seems Chrome 4.1 only sends the hidden argument, and removes the repname parameter altogether. Is this correct? I fixed it temporarily, pending more information, by adding another hidden field for repname with the same value, and now everything works, I'm just wondering if Chrome or WebSVN is in fault here.

• What programs should I write to truly experience this fancy new language ?

  - by privatehuff

  Tried Scheme at one point, just built up half of a "math" and "string" library before getting bored... Similar experience with Java, but stopped early because I was appalled at the lack of operator overloading. When you try out a new language, is there a program/game/function/exercise/problem that you use to get into the hot meaty center and really EXPERIENCE the language? I've been wanted to try Python, Ruby, some lisps, etc but can't seem to find any meaningful work to do with them, or any reason to use them for anything over languages I already know. Sorry this is a discussion, but you are EXACTLY the people I want to get input from on this

• analysis Big Oh notation psuedocode

  - by tesshu

  I'm having trouble getting my head around algorithm analysis. I seem to be okay identifying linear or squared algorithms but am totally lost with nlogn or logn algorithms, these seem to stem mainly from while loops? Heres an example I was looking at: Algorithm Calculate(A,n) Input: Array A of size n t?0 for i?0 to n-1 do if A[i] is an odd number then Q.enqueue(A[i]) else while Q is not empty do t?t+Q.dequeue() while Q is not empty do t?t+Q.dequeue() return t My best guess is the for loop is executed n times, its nested while loop q times making NQ and the final while loop also Q times resulting in O(NQ +Q) which is linear? I am probably totally wrong. Any help would be much appreciated. thanks

• Use only some parts of Django?

  - by Hanno Fietz

  I like Django, but for a particular application I would like to use only parts of it, but I'm not familiar enough with how Django works on the inside, so maybe someone can point me into the right direction as to what I have to check out. Specifically, I want to use: The models and database abstraction The caching API, although I want to avoid database lookups by caching, not HTML generation, and since the caching framework in Django is intended for the latter, I'm not sure yet whether that's really appropriate. I would not use: Templating urlconfigs Or, more exactly, I'm neither using HTTP nor HTML. So basically, I have a different input / output chain than usual. Can this work? My personal killer feature in Django is the Object / database mapping that I can do with the models, so if there's another technology (doesn't have to be Python, I'm in the design phase and I'm pretty agnostic about languages and platforms) that gives me the same abilities, that would be great, too.

• Run JavaScript after a DropDownList is DataBound

  - by Daniel Coffman

  I need to trigger a JavaScript function to be called AFTER a DropDownList on my ASP.NET WebForms page is DataBound, because the SelectedIndex of this DropDownList is the parameter to the JavaScript function. I've tried this various ways, but it seems that if I do it with pure JavaScript onload by using ClientScript.RegisterStartUpScript, the control can be found (because it hasn't been assigned a clientID yet?). If I use jQuery (document).ready { } it says that the DropDownList has no selectedIndex.value. So I need some JavaScript to run AFTER the control has a value set by the DataBind. How can I accomplish this? onChanged won't work because I need the function to fire on the first page load, with no user input. DataBinding the SelectedIndex of the DropDownList doesn't cause the JavaScript onChanged event to fire.

• How can I use images provided by the iPhone OS?

  - by Topher Fangio

  Hello all, First, let me state what brought this question about: I saw the green checkmark icon in this post and I would like to use it in my own application. However, since it looks so much like the UITableViewCellAccessoryDetailDisclosureButton my assumption is that this green checkmark icon is provided by the iPhone OS in some form or fashion. So, my question is: how can I use the green checkmark icon and/or other OS-provided images in my own applications? As a side question: where can I find a list of the OS-provided images (if they even exist)? Thanks very much for any input :-)

• Spring - disable bind exceptions (for a particular property)

  - by Walter White

  Hi all, In a web application I'm working on using Spring 2.5.6.SEC01, I essentially have an Integer field that takes a number to determine which page to scroll to. The requirements changed, and we no longer want to display an error message, but simply ignore the user's input if they enter an invalid number, say "adfadf". I was reading that you can do that via: TypeMismatch.property=Some New Error Message However, after having tried that, we are still getting the original error message: java.lang.Integer.TypeMismatch=... I only want to disable this message for that given property. How can I do that? I still want binding to occur automatically, I just don't want to hear about it now. Walter

I call e.serializeArray() Here is my test. equals(args.data, [ { "name": "user_name", "value": "john" } ], 'input data'); And this is the error message from qunit. expected: [ { "name": "user_name", "value": "david" } ] result: [ { "name": "user_name", "value": "david" } ] As you can see to the naked eye the expected and result value is same but qunit is not liking it. I guess I am missing something.
