  • I am getting error when using Attributes in Rcpp and have RcppArmadillo code

    - by howard123
    I am trying to create a package with RcppArmadillo. The code uses the new attributes methodology of Rcpp. The sourceCpp works fine and compiles the code, but when I build a package I get errors when I use RcppArmadillo code. Without the RcppArmadillo code and using regulare C++, I do not get these errors. The C++ code (it is essentially the fastLm sample code) is: // [[Rcpp::depends(RcppArmadillo)]] #include <Rcpp.h> #include <RcppArmadillo.h> using namespace Rcpp; // [[Rcpp::depends(RcppArmadillo)]] #include <RcppArmadillo.h> // [[Rcpp::export]] List fastLm(NumericVector yr, NumericMatrix Xr) { int n = Xr.nrow(), k = Xr.ncol(); arma::mat X(Xr.begin(), n, k, false); arma::colvec y(yr.begin(), yr.size(), false); arma::colvec coef = arma::solve(X, y); arma::colvec resid = y - X*coef; double sig2 = arma::as_scalar(arma::trans(resid)*resid/(n-k)); arma::colvec stderrest = arma::sqrt( sig2 * arma::diagvec( arma::inv(arma::trans(X)*X)) ); return List::create(Named("coefficients") = coef, Named("stderr") = stderrest); } Here is the compilation error, after I execute "R

  • The DOS DEBUG Environment

    - by MarkPearl
    Today I thought I would go back in time and have a look at the DEBUG command that has been available since the beginning of dawn in DOS, MS-DOS and Microsoft Windows. up to today I always knew it was there, but had no clue on how to use it so for those that are interested this might be a great geek party trick to pull out when you want the awe the younger generation and want to show them what “real” programming is about. But wait, you will have to do it relatively quickly as it seems like DEBUG was finally dumped from the Windows group in Windows 7. Not to worry, pull out that Windows XP box which will get you even more geek points and you can still poke DEBUG a bit. So, for those that are interested and want to find out a bit about the history of DEBUG read the wiki link here. That all put aside, lets get our hands dirty.. How to Start DEBUG in Windows Make sure your version of Windows supports DEBUG. Open up a console window Make a directory where you want to play with debug – in my instance I called it C221 Enter the directory and type Debug You will get a response with a – as illustrated in the image below…   The commands available in DEBUG There are several commands available in DEBUG. The most common ones are A (Assemble) R (Register) T (Trace) G (Go) D (Dump or Display) U (Unassemble) E (Enter) P (Proceed) N (Name) L (Load) W (Write) H (Hexadecimal) I (Input) O (Output) Q (Quit) I am not going to cover all these commands, but what I will do is go through a few of them briefly. A is for Assemble Command (to write code) The A command translates assembly language statements into machine code. It is quite useful for writing small assembly programs. Below I have written a very basic assembly program. The code typed out is as follows mov ax,0015 mov cx,0023 sub cx,ax mov [120],al mov cl,[120]A nop R is for Register (to jump to a point in memory) The r command turns out to be one of the most frequent commands you will use in DEBUG. It allows you to view the contents of registers and to change their values. It can be used with the following combinations… R – Displays the contents of all the registers R f – Displays the flags register R register_name – Displays the contents of a specific register All three methods are illustrated in the image above T is for Trace (To execute a program step by step) The t command allows us to execute the program step by step. Before we can trace the program we need to point back to the beginning of the program. We do this by typing in r ip, which moves us back to memory point 100. We then type trace which executes the first line of code (line 100) (As shown in the image below starting from the red arrow). You can see from the above image that the register AX now contains 0015 as per our instruction mov ax,0015 You can also see that the IP points to line 0103 which has the MOV CX,0023 command If we type t again it will now execute the second line of the program which moves 23 in the cx register. Again, we can see that the line of code was executed and that the CX register now holds the value of 23. What I would like to highlight now is the section underlined in red. These are the status flags. The ones we are going to look at now are 1st (NV), 4th (PL), 5th (NZ) & 8th (NC) NV means no overflow, the alternate would be OV PL means that the sign of the previous arithmetic operation was Plus, the alternate would be NG (Negative) NZ means that the results of the previous arithmetic operation operation was Not Zero, the alternate would be ZR NC means that No final Carry resulted from the previous arithmetic operation. CY means that there was a final Carry. We could now follow this process of entering the t command until the entire program is executed line by line. G is for Go (To execute a program up to a certain line number) So we have looked at executing a program line by line, which is fine if your program is minuscule BUT totally unpractical if we have any decent sized program. A quicker way to run some lines of code is to use the G command. The ‘g’ command executes a program up to a certain specified point. It can be used in connection with the the reset IP command. You would set your initial point and then run the G command with the line you want to end on. P is for Proceed (Similar to trace but slightly more streamlined) Another command similar to trace is the proceed command. All that the p command does is if it is called and it encounters a CALL, INT or LOOP command it terminates the program execution. In the example below I modified our example program to include an int 20 at the end of it as illustrated in the image below… Then when executing the code when I encountered the int 20 command I typed the P command and the program terminated normally (illustrated below). D is for Dump (or for those more polite Display) So, we have all these assembly lines of code, but if you have ever opened up an exe or com file in a text/hex editor, it looks nothing like assembly code. The D command is a way that we can see what our code looks like in memory (or in a hex editor). If we examined the image above, we can see that Debug is storing our assembly code with each instruction following immediately after the previous one. For instance in memory address 110 we have int and 111 we have 20. If we examine the dump of memory we can see at memory point 110 CD is stored and at memory point 111 20 is stored. U is for Unassemble (or Convert Machine code to Assembly Code) So up to now we have gone through a bunch of commands, but probably one of the most useful is the U command. Let’s say we don’t understand machine code so well and so instead we want to see it in its equivalent assembly code. We can type the U command followed by the start memory point, followed by the end memory point and it will show us the assembly code equivalent of the machine code. E is for a bunch of things… The E command can be used for a bunch of things… One example is to enter data or machine code instructions directly into memory. It can also be used to display the contents of memory locations. I am not going to worry to much about it in this post. N / L / W is for Name, Load & Write So we have written out assembly code in debug, and now we want to save it to disk, or write it as a com file or load it. This is where the N, L & W command come in handy. The n command is used to give a name to the executable program file and is pretty simple to use. The w command is a bit trickier. It saves to disk all the memory between point bx and point cx so you need to specify the bx memory address and the cx memory address for it to write your code. Let’s look at an example illustrated below. You do this by calling the r command followed by the either bx or cx. We can then go to the directory where we were working and will see the new file with the name we specified. The L command is relatively simple. You would first specify the name of the file you would like to load using the N command, and then call the L command. Q is for Quit The last command that I am going to write about in this post is the Q command. Simply put, calling the Q command exits DEBUG. Commands we did not Cover Out of the standard DEBUG commands we covered A, T, G, D, U, E, P, R, N, L & W. The ones we did not cover were H, I & O – I might make mention of these in a later post, but for the basics they are not really needed. Some Useful Resources Please note this post is based on the COS2213 handouts for UNISA A Guide to DEBUG - http://mirror.href.com/thestarman/asm/debug/debug.htm#NT

  • I'm graduating with a Computer Science degree but I don't feel like I know how to program.

    - by wp123
    I'm graduating with a Computer Science degree but I see websites like Stack Overflow and search engines like Google and don't know where I'd even begin to write something like that. During one summer I did have the opportunity to work as a iPhone developer, but I felt like I was mostly gluing together libraries that other people had written with little understanding of the mechanics happening beneath the hood. I'm trying to improve my knowledge by studying algorithms, but it is a long and painful process. I find algorithms difficult and at the rate I am learning a decade will have passed before I will master the material in the book. Given my current situation, I've spent a month looking for work but my skills (C, Python, Objective-C) are relatively shallow and are not so desirable in the local market, where C#, Java, and web development are much higher in demand. That is not to say that C and Python opportunities do not exist but they tend to demand 3+ years of experience I do not have. My GPA is OK (3.0) but it's not high enough to apply to the large companies like IBM or return for graduate studies. Basically I'm graduating with a Computer Science degree but I don't feel like I've learned how to program. I thought that joining a company and programming full-time would give me a chance to develop my skills and learn from those more experienced than myself, but I'm struggling to find work and am starting to get really frustrated. I am going to cast my net wider and look beyond the city I've grown up in, but what have other people in similar situation tried to do? I've worked hard but don't have the confidence to go out on my own and write my own app. (That is, become an indie developer in the iPhone app market.) If nothing turns up I will need to consider upgrading and learning more popular skills or try something marginally related like IT, but given all the effort I've put in that feels like copping out. EDIT: Thank you for all the advice. I think I was premature because of unrealistic expectations but the comments have given me a dose of reality. I will persevere and continue to code. I have a project in mind, although well beyond my current capabilities it will challenge me to hone my craft and prove my worth to myself (and potential employers). Had I known there was a career overflow I would have posted there instead. Thanks again!

  • Java Grade Calculator program for class kepp geting the error "Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException." [migrated]

    - by user2880621
    this is my first question I've posted. I've used this site to look at other questions to help with similar problems I've had. After some cursory looking I couldn't find quite the answer I was looking for so I decided to finally succumb and create an account. I am fairly new to java, only a few weeks into my first class. Anyway, my project is to create a program which takes any amount of students and their grades, and then assign them a letter grade. The catch is, however, that it is on a sort of curve and the other grades' letter are dependent on the the highest. Anything equal to or 10 points below the best grade is an a, anything 11-20 points below is a b, and so on. I am to use an array, but I get this error when ran "Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException." I will go ahead and post my code down below. Thanks for any advice you may be able to give. package grade.calculator; import java.util.Scanner; /** * * @author nichol57 */ public class GradeCalculator { /** * @param args the command line arguments */ public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.println("Enter the number of students"); int number = input.nextInt(); double[]grades = new double [number]; for (int J = number; J >=0; J--) { System.out.println("Enter the students' grades"); grades[J] = input.nextDouble(); } double best = grades[0]; for (int J = 1; J < number; J++) { if (grades[J] >= best){ best = grades[J]; } } for (int J = 0;J < number; J++){ if (grades[J] >= best - 10){ System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "A"); } else if (grades[J] >= best - 20){ System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "B"); } else if (grades[J] >= best - 30) { System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "C"); } else if (grades[J] >= best - 40) { System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "D"); } else { System.out.println("Student " + J + " score is " + grades[J] + " and grade is " + "F"); } } // end for loop for output }// end main method }

  • C Programming arrays, I dont understand how I would go about making this program, If anyone can just guide me through the basic outline please :) [on hold]

    - by Rashmi Kohli
    Problem The temperature of a car engine has been measured, from real-world experiments, as shown in the table and graph below: Time (min) Temperature (oC) 0 20 1 36 2 61 3 68 4 77 5 110 Use linear regression to find the engine’s temperature at 1.5 minutes, 4.3 minutes, and any other time specified by the user. Background In engineering, many times we measure several data points in an experiment, but then we need to predict a value that we have not measured which lies between two measured values, such as the problem statement above. If the relation between the measured parameters seems to be roughly linear, then we can use linear regression to find the relationship between those parameters. In the graph of the problem statement above, the relation seems to be roughly linear. Hence, we can apply linear regression to the above problem. Assuming y {y0, y1, …yn-1} has a linear relation with x {x0, x1, … xn-1}, we can say that: y = mx+b where m and b can be found with linear regression as follows: For the problem in this lab, using linear regression gives us the following line (in blue) compared to the measured curve (in red). As you can see, there is usually a difference between the measured values and the estimated (predicted) values. What linear regression does is to minimize those differences and still give us a straight line (blue). Other methods, such as non-linear regression, are also possible to achieve higher accuracy and better curve fitting. Requirements Your program should first print the table of the temperatures similar to the way it’s printed in the problem statement. It should then calculate the temperature at minute 1.5 and 4.3 and show the answers to the user. Next, it should prompt the user to enter a time in minutes (or -1 to quit), and after reading the user’s specified time it should give the value of the engine’s temperature at that time. It should then go back to the prompt. Hints •Use a one dimensional array to store the temperature values given in the problem statement. •Use functions to separate tasks such as calculating m, calculating b, calculating the temperature at a given time, printing the prompt, etc. You can then give your algorithm as well as you pseudo code per function, as opposed to one large algorithm diagram or one large sequence of pseudo code.

  • Is there any program (or code, any language) that will mute all of the microphones on my computer?

    - by Sean
    Is there any program (or code, any language) that will mute all of the microphones on my computer? If it is code, please make it as simple as possible, the only language I know is C# and I am still VERY new to it. I just want to setup some way to mute my microphones from a hotkey/shortcut, and if I can just find a program that can do, I will be set. As I said, I can also do a little bit if it is in C#, but the only code I have seen before for this, was miles long (atleast to me). My goal, is I just want a program that opens up, and toggles the mute on the microhpones (all of the system audio input) then closes. That is it, very simple. Thank you to anyone who trys to helps me! EDIT: Yes, I am using Windows. I am using Windows 7 32-bit. I already know that I can go into the volume mixer and do it that way, but I need to do this while running a full screen application, and it is a hassle to have to exit fullscreen, open the volume mixer, the click the mute icon, then go back into full screen and the the whole thing over again to unmute it. And I will be toggling back and forth quite often, so it just takes alot to do that so much.

  • What is causing sudden freezing during running real-time program?

    - by Trevor Boyd Smith
    So I run a high intensive (CPU/GPU) real-time program. During normal execution suddenly everything freezes for 1-4 seconds. I opened "Process Explorer" in the background to help gain insight and maybe identify something. Here is what the CPU/GPU graphs looks like when I align them in time: Notice the 4 distinct drops in both the CPU/GPU. You can see that it goes from some sort of positive CPU/GPU usage to almost zero. These drops in the graph align with when the real-time program suddenly freezes. How do I find what is causing these sudden drops? NOTE: When you put your mouse over the graph it tells you the time, accurate to the second, for where your cursor is. Maybe this mouse over feature could be helpful in some way (e.g. what if you had a log of all processes every 100ms). EDIT: The real-time program is a video game and so I can't watch some sort of instrumentation while the video game is running. I need a solution that let's you look back in time somehow to see what was happening when the slow down occurred. EDIT: RE - Recording Data vs using real-time monitor: So the windows performance recorder is for some reason not recording what I expect it to record. So I switched to using "perfmon" and then opening it's "resource monitor". RE - Setting it up so I can view real-time monitor: In the video game I set it to spectate and then put the video game in "windowed" mode so that I can view the real time display that Resource Monitor has. Now that I can get semi-real time (only once per second... how do you get more than once per second?) I started looking at the various real time data readouts. Getting to the cause: I noticed a strong correlation in high disk IO and low CPU usage (which is also seen by having in-game freezing). How do you use resource monitor to find out who is doing all this offending disk IO?

  • Any program to help me check whether an ethernet channel can support full-length VLAN packet?

    - by Jimm Chen
    Sometimes, I have to face such a situation that I need to quickly and explicitly know whether a full length VLAN packet can traverse between two RJ45 ports. Yes, I mean 802.1Q ethernet frame with Etype=81 00 (diagram below). What I can do now is: Get two Windows PCs, for each PC, intall Intel Gigabit NIC and Intel specific driver to create a virtual NIC, with VLAN ID=3 assigned. Then connect the two PCs to each of the two RJ45 port. Finally execute ping to generate a full-length ethernet packet. ping -f -l 1472 <dest-IP> This way, I can be sure that the sent packet has the maximum "IP data payload" of 1500 bytes(8 bytes of ICMP header and 1472 bytes of ICMP data). If the ping gets reply, I know that the ethernet channel support full-length VLAN packet. From my experiment, some home switch or broad band routers(e.g. Linksys WRT54G) does not support full-length VLAN packet switching, so only ping -f -l 1468 succeeds. You see, I have to use an expensive Intel NIC to carry on that test, quite inconvenient. You know, for most laptop today, they do not equip an Intel NIC, and, even it is an Intel NIC, Intel VLAN driver, Intel has limitations on the models on which VLAN driver can be installed. So, my question is: Is there a small program that can let me send a full-length VLAN packet without installing a dedicated VLAN driver? Or better, the program has a stock feature that does the very job for my situation. Windows programs preferred, Linux solution welcome. Simpler the program, the better. Thank you.

    Summary I want to be able to call a JavaScript function from a Flex app using ExternalInterface and pass a reference to a different JavaScript function as an argument. Base Example Given the following JavaScript: function foo(callback) { // ... do some stuff callback(); } function bar() { // do some stuff that should happen after a call to foo } I want to call foo from my flex app using ExternalInterface and pass a reference to bar as the callback. Why Really,foo is not my function (but, rather, FB.Connect.showBookmarkDialog), which due to restrictions on Facebook iframe apps can only be called on a button click. My button, for design reasons, is in the Flex app. Fortunately, it's possible to call ExternalInterface.call("FB.Connect.showBookmarkDialog", callback) to display the bookmark dialog. But, FB.Connect.showBookmarkDialog requires a JS callback so, should I want to receive a callback (which I do), I need to pass a reference to a JS function as the single argument. Real Example MXML: <mx:Button click="showBookmarkDialog();" /> ActionScript: function showBookmarkDialog() : void { ExternalInterface.registerCallback( "onBookmarkDialogClosed", onBookmarkDialogClosed ); ExternalInterface.call( "FB.Connect.showBookmarkDialog", /* ref to JS function onBookmarkDialogClosed ? */ ); } function onBookmarkDialogClosed(success:Boolean) : void { // sweet, we made it back } JavaScript: function onBookmarkDialogClosed() { var success; // determine value of success getSWF().onBookmarkDialogClosed(success); } Failed Experiments I have tried... ExternalInterface.call( "FB.Connect.showBookmarkDialog", "onBookmarkDialogClosed" ); ExternalInterface.call( "FB.Connect.showBookmarkDialog", onBookmarkDialogClosed ); ExternalInterface.call( "FB.Connect.showBookmarkDialog", function() : void { ExternalInterface.call("onBookmarkDialogClosed"); } ); ExternalInterface.call( "FB.Connect.showBookmarkDialog", function() { this["onBookmarkDialogClosed"](); } ); Of note: Passing a string as the argument to an ExternalInterface call results in FB's JS basically trying to do `"onBookmarkDialogClosed"()` which, needless to say, will not work. Passing a function as the argument results in a function object on the other side (confirmable with `typeof`), but it seems to be an empty function; namely, `function Function() {}`

  • Can I get a reference to a pending transaction from a SqlConnection object?

    - by Rune
    Hey, Suppose someone (other than me) writes the following code and compiles it into an assembly: using (SqlConnection conn = new SqlConnection(connString)) { conn.Open(); using (var transaction = conn.BeginTransaction()) { /* Update something in the database */ /* Then call any registered OnUpdate handlers */ InvokeOnUpdate(conn); transaction.Commit(); } } The call to InvokeOnUpdate(IDbConnection conn) calls out to an event handler that I can implement and register. Thus, in this handler I will have a reference to the IDbConnection object, but I won't have a reference to the pending transaction. Is there any way in which I can get a hold of the transaction? In my OnUpdate handler I want to execute something similar to the following: private void MyOnUpdateHandler(IDbConnection conn) { var cmd = conn.CreateCommand(); cmd.CommandText = someSQLString; cmd.CommandType = CommandType.Text; cmd.ExecuteNonQuery(); } However, the call to cmd.ExecuteNonQuery() throws an InvalidOperationException complaining that "ExecuteNonQuery requires the command to have a transaction when the connection assigned to the command is in a pending local transaction. The Transaction property of the command has not been initialized". Can I in any way enlist my SqlCommand cmd with the pending transaction? Can I retrieve a reference to the pending transaction from the IDbConnection object (I'd be happy to use reflection if necessary)?

  • Service reference error when moving dev. environment from XP to W7

    - by Peter
    Hi, I am building an application and I am using web services for getting data from a server. It was working fine when I was developing on my XP machine but had to switch to Windows 7. On the new machine I grabbed the latest version of the code using sourcesafe. However, when I try to add a service reference in the solution or update an existing one I get the following error: There was an error downloading 'http://localhost:52490/Service/CustomerService.asmx'. The request failed with the error message: Server Error in '/' Application. Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Could not create type 'Digital_Server.CustomerService'. Source Error <%@ WebService Language="vb" CodeBehind="CustomerService.asmx.vb" Class="Digital_Server.CustomerService" % Source File: /Service/CustomerService.asmxLine: 1 Version Information: Microsoft .NET Framework Version:2.0.50727.4927; ASP.NET Version:2.0.50727.4927 --. Metadata contains a reference that cannot be resolved: 'http://localhost:52490/Service/CustomerService.asmx'. An error occurred while receiving the HTTP response to http://localhost:52490/Service/CustomerService.asmx. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details. The underlying connection was closed: An unexpected error occurred on a receive. Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host. An existing connection was forcibly closed by the remote host If the service is defined in the current solution, try building the solution and adding the service reference again. Does it has anything to do with the IIS or is it any configuration file I have to change in the solution? Any help is appreciated.

  • How do I reference my MainViewController from another class?

    - by todd412
    Hi, I am building an iPhone Utility app that uses UIImageView to display an animation. Within the MainViewController's viewDidLoad() method, I am creating an instance of a CustomClass, and then setting up the animations: - (void)viewDidLoad { [super viewDidLoad]; cc = [CustomClass new]; NSArray * imageArray = [[NSArray alloc] initWithObjects: [UIImage imageNamed:@"image-1-off.jpg"], [UIImage imageNamed:@"image-2-off.jpg"], [UIImage imageNamed:@"image-3-off.jpg"], [UIImage imageNamed:@"image-4-off.jpg"], nil]; offSequence = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; offSequence.animationImages = imageArray; offSequence.animationDuration = .8; offSequence.contentMode = UIViewContentModeBottomLeft; [self.view addSubview:offSequence]; [offSequence startAnimating]; } That works fine. However, I would like to be able to move all the above code that sets up the UIImageView into my CustomClass. The problem is in the second to last line: [self.view addSubview:offSequence]; I basically need to replace 'self' with a reference to the MainControllerView, so I can call addSubview from within my CustomClass. I tried creating an instance var of CustomClass called mvc and a setter method that takes a reference to the MainViewController as an argument as such: - (void) setMainViewController: (MainViewController *) the_mvc { mvc = the_mvc; } And then I called it within MainViewController like so: [cc setMainController:MainViewController:self]; But this yields all sorts of errors which I can post here, but it strikes me that I may be overcomplicating this. Is there an easier way to reference the MainViewController that instanatiated my CustomClass?

  • How do I reference an instance of a class using its tag?

    - by Matt Winters
    I have several instances of a UIControl class Foo being instantiated, one instance corresponding to each cell in a UITableView. The Class has: BOOL selected; UIImageView *imageView; UIImage *imageOne; UIImage *imageTwo; I've assigned each instance a tag: foo.tag = indexPath.row; I would now like to reference the UIImageView.image for a (or several) specific instance(s) by its tag to switch it to the other image. In my search I've seen things like classes being assigned tags using initWithTag (I assume they're assigning tags)... SomeClass *someClass = [[SomeClass alloc]initWithTag:1 ... [someArray addObject: [[SomeClass alloc]initWithTag:2 ... [someArray addObject: [[SomeClass alloc]initWithTag:3 ... ...but I haven't seen how they are later referenced by that tag. I have seen a reference to getChildByTag which had promise, but I can't find it in the documentation or examples (maybe not iphone). Does anyone know how reference the imageView.image within an instance using its tag? Thanks

  • What is the best way to get a reference to a spring bean in the backend layers?

    - by java_pill
    I have two spring config files and I'm specifying them in my web.xml as in below. web.xml snippet .. <context-param> <param-name>contextConfigLocation</param-name> <param-value>WEB-INF/classes/domain-context.xml WEB-INF/classes/client-ws.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> .. From my domain object I have to invoke a Web Service Client and in order to get a reference to the Web Service client I do this: ApplicationContext context = new ClassPathXmlApplicationContext("client-ws.xml"); //b'cos I don't want to use WebApplicationContextUtils ProductServiceClient client = (ProductServiceClient) context.getBean("productClient"); .. client.find(prodID); //calls a Web Service .. However, I have concerns that looking up the client-ws.xml file and getting a reference to the ProductServiceClient bean is not efficient. I thought of getting it using WebApplicationContextUtils. However, I don't want my domain objects to have a dependency on the ServletContext (a web/control layer object) because WebApplicationContextUtils depends on ServletContext. What is the best way to get a reference to a spring bean in the backend layers? Thanks!

  • Is it possible to reference remote content from chrome.manifest? (XULRunner)

    - by siemaa
    Hi, I have a xulrunner application and I've been trying to reference remote content from chrome.manifest file. Tt's an application for the company I work in; it's run on a number of computers (most of them are used by other employees as well) as a kind of an internet monitoring service. The problem I'd like to solve is this: updating the code of such application usually requires me to manually copy the modified files to every computer that the application is running on (I've had no luck trying to make automatic updates via xulrunner platform). This process has become very tedious. What I'd like to have is a web server, where all of the xul and js files would be accessible, so that every application could reference them from there. This would require me only to update the code on that server, and the applications (when restarted) would automatically get the latest code. What I managed to do: I can reference js scripts from a xul file using http based urls and everything works fine (I can use local, binary components etc.), although the xul file has to be local - that I'd like to change. But when I write in chrome.manifest a line like: content my_app http://path/to/app/files/ and then use the line in default/preferences/pref.js pref("toolkit.defaultChromeURI", "chrome://my_app/content/my_app.xul"); it just opens a console window (to test I manually run the application with the -console option) and no code gets executed. The file can be downloaded remotely using wget so I guess this isn't the web server issue. The applications work on Windows machines. Is there some kind of security issue causing such behavior or am I doing something wrong? Is it even possible to register remote, http based content as chrome?

  • how to write the code for this program specially in mathematica? [closed]

    - by asd
    I implemented a solution to the problem below in Mathematica, but it takes a very long time (hours) to compute f of kis or the set B for large numbers. Somebody suggested that implementing this in C++ resulted in a solution in less than 10 minutes. Would C++ be a good language to learn to solve these problems, or can my Mathematica code be improved to fix the performance issues? I don't know anything about C or C++ and it should be difficult to start to learn this languages. I prefer to improve or write new code in mathematica. Problem Description Let $f$ be an arithmetic function and A={k1,k2,...,kn} are integers in increasing order. Now I want to start with k1 and compare f(ki) with f(k1). If f(ki)f(k1), put ki as k1. Now start with ki, and compare f(kj) with f(ki), for ji. If f(kj)f(ki), put kj as ki, and repeat this procedure. At the end we will have a sub sequence B={L1,...,Lm} of A by this property: f(L(i+1))f(L(i)), for any 1<=i<=m-1 For example, let f is the divisor function of integers. Here I put some part of my code and this is just a sample and the question in my program could be more larger than these: «««««««««««««««««««««««««««««««««««« f[n_] := DivisorSigma[0, n]; g[n_] := Product[Prime[i], {i, 1, PrimePi[n]}]; k1 = g[67757] g[353] g[59] g[19] g[11] g[7] g[5]^2 6^3 2^7; k2 = g[67757] g[353] g[59] g[19] g[11] g[7] g[5] 6^5 2^7; k3 = g[67757] g[359] g[53] g[19] g[11] g[7] g[5] 6^4 2^7; k4 = g[67759] g[349] g[53] g[19] g[11] g[7] g[5] 6^5 2^6; k5 = g[67757] g[359] g[53] g[19] g[11] g[7] g[5] 6^4 2^8; k6 = g[67759] g[349] g[53] g[19] g[11] g[7] g[5]^2 6^3 2^7; k7 = g[67757] g[359] g[53] g[19] g[11] g[7] g[5] 6^5 2^6; k8 = g[67757] g[359] g[53] g[19] g[11] g[7] g[5] 6^4 2^9; k9 = g[67757] g[359] g[53] g[19] g[11] g[7] g[5]^2 6^3 2^7; k10 = g[67757] g[359] g[53] g[19] g[11] g[7] g[5] 6^5 2^7; k11 = g[67759] g[349] g[53] g[19] g[11] g[7] g[5]^2 6^4 2^6; k12 = g[67757] g[359] g[53] g[19] g[11] g[7] g[5]^2 6^3 2^8; k13 = g[67757] g[359] g[53] g[19] g[11] g[7] g[5]^2 6^4 2^6; k14 = g[67757] g[359] g[53] g[19] g[11] g[7] g[5]^2 6^3 2^9; k15 = g[67757] g[359] g[53] g[19] g[11] g[7] g[5]^2 6^4 2^7; k16 = g[67757] g[359] g[53] g[23] g[11] g[7] g[5] 6^4 2^8; k17 = g[67757] g[359] g[59] g[19] g[11] g[7] g[5] 6^4 2^7; k18 = g[67757] g[359] g[53] g[23] g[11] g[7] g[5] 6^4 2^9; k19 = g[67759] g[353] g[53] g[19] g[11] g[7] g[5] 6^4 2^6; k20 = g[67763] g[347] g[53] g[19] g[11] g[7] g[5] 6^4 2^7; k = Table[k1, k2, k3, k4, k5, k6, k7, k8, k9, k10, k11, k12, k13, k14, k15, k16, k17, k18, k19, k20]; i = 1; count = 0; For[j = i, j <= 20, j++, If[f[k[[j]]] - f[k[[i]]] > 0, i = j; Print["k",i]; count = count + 1]]; Print["count= ", count] ««««««««««««««««««««««««««««««««««««

  • Blind As a Bat in Multi-Monitor Hell &ndash; Free Program Inside!

    - by ToStringTheory
    If you know me personally, then you probably know that I am going blind thanks to a rare genetic eye disease.  My eye disease has already been a huge detriment to my eyesight.  One of the big things to suffer is my ability to see small things moving fast right in front of me.  On a multi-monitor setup, this makes finding the cursor absolute hell. The Problem I’ll keep this short, as I’ve basically already told you what the problem is.  On my three monitor development computer, I am constantly losing the mouse during the day.  I had used the Microsoft accessibility mousefinder (press CTRL, and it pings around the mouse).  The problem with this is, there is only an effect around 50-100 PX around the mouse, and it is a very light gray, almost unnoticeable.. For someone like me, if I am not looking at the monitor when I click the CTRL button, I have to click it multiple times and dart my eyes back and forth in a futile attempt to catch a glimpse of the action…  I had tried other cursor finders, but none I liked… The Solution So what’s a guy to do when he doesn’t like his options?  MAKE A NEW OPTION…  What else should we as developers do, am I right?  So, I went ahead and made a mousefinder of my own, with 6 separate settings to change the effect.  I am releasing it here for anyone else that may also have problems finding their mouse at times. Some of its features include: Multiple options to change to achieve the exact effect you want. If your mouse moves while it is honing in, it will hone in on its current position. Many times, I would press the button and move my mouse at the same time, and many times, the mouse happened to be at a screen edge, so I would miss it. This program will restart its animation on a new screen if the mouse changes its screen while playing. Tested on Windows 7 x64 Stylish color changing from green to red. Deployed as a ClickOnce, so easy to remove if you don't like it. Press Right CTRL to trigger effect Application lives in notification area so that you can easily reach configuration or close it. To get it to run on startup, copy its application shortcut from its startmenu directory to the “Startup” folder in your startmenu. Conclusion I understand if you don’t download this…  You don’t know me and I don’t know you.  I can only say that I have honestly NOT added any virus’ or malware to the package. Yeah, I know it’s weird Download: ‘ToString(theory) Mousefinder.zip’ CRC32: EEBCE300 MD5: 0394DA581BE6F3371B5BA11A8B24BC91 SHA-1: 2080C4930A2E7D98B81787BB5E19BB24E118991C Finally, if you do use this application - please leave a comment, or email me and tell me what you think of it. Encounter a bug or hashes no longer match? I want to know that too! <warning type=”BadPun”>Now, stop messing around and start mousing around!</warning>

  • Circular file references not allowed

    - by Program.X
    Hi, I am having a problem in building my solution in VS2008. Normally, it compiles fine in the environment. Sometimes, it fails with: /xxx_WEB/secure/CMSManagedTargetPage.aspx(1): error ASPPARSE: Circular file references are not allowed. I rebuild and it works fine. Now, however, I am in the middle of setting up a CruiseControl.NET system and am testing my checked out code with MSBuild before I integrate the build into CC. Now, everytime I MSBuild, I get: "Q:\cc\xxx\checked out from svn\xxx.sln" (default target) (1) -> (xxx_WEB target) -> /xxx_WEB/secure/CMSManagedTargetPage.aspx(1): error ASPPARSE: Circular file references are not allowed. Problem is, I can't see where this reference is. I have searched for the reference across the entire solution and canf ind no references to the page itself (CMSManagedTargetPage) anywhere other than in the page or its codebehind, or within a string, eg: C:\dev2008\xxx\IWW.xxx.ASPNET\AspxHttpHandler.cs(82): inputFile = context.Server.MapPath("~/secure/CMSManagedTargetPage.aspx"); C:\dev2008\xxx\IWW.xxx.ASPNET\AspxHttpHandler.cs(83): virtualPath = "~/secure/CMSManagedTargetPage.aspx"; My assembly references are also fine (as far as I know). My Web Application is at the "top" of the dependencies, and nothing references it and therefore the faulting page so cannot cause a circular reference. Of course, the page itself may reference something such as a UserControl within the same assembly/web site, but as mentioned earlier, a search on CMSManagedTargetPage yielded no results so this is not happening. Changing the batch attribute in web.config had no effect on MSBuild. I find it very odd that it "sometimes" fails in VS and always fails in MSBuild. Am I missing some subtlety?

  • Compile PHP Error with freetype

    - by Robert Ross
    Hey Guys, I configured PHP myself, included all of the libraries I needed... but then realized I forgot the freetype library. So I went back to my php-5.3.2 directory and ran ./configure '--with-free-type=/usr/local/lib' PHP did the configure fine, no errors. But when I run make: collect2: ld returned 1 exit status make: *** [sapi/cgi/php-cgi] Error 1 Something that comes up frequently: /php-5.3.2/ext/libxml/libxml.c:336: undefined reference to `ts_resource_ex' /php-5.3.2/ext/sqlite3/sqlite3.c:663: undefined reference to `executor_globals_id' ext/sqlite3/.libs/sqlite3.o: In function `php_sqlite3_callback_final': /php-5.3.2/ext/sqlite3/sqlite3.c:811: undefined reference to `ts_resource_ex' ext/sqlite3/.libs/sqlite3.o: In function `php_sqlite3_callback_step': /php-5.3.2/ext/sqlite3/sqlite3.c:799: undefined reference to `ts_resource_ex' ext/sqlite3/.libs/sqlite3.o: In function `php_sqlite3_callback_func': /php-5.3.2/ext/sqlite3/sqlite3.c:788: undefined reference to `ts_resource_ex' ext/sqlite3/.libs/sqlite3.o: In function `php_sqlite3_authorizer': /php-5.3.2/ext/sqlite3/sqlite3.c:1782: undefined reference to `ts_resource_ex' /php-5.3.2/ext/sqlite3/sqlite3.c:1787: undefined reference to `core_globals_id' ext/sqlite3/.libs/sqlite3.o: In function `zim_sqlite3_open': /php-5.3.2/ext/sqlite3/sqlite3.c:161: undefined reference to `core_globals_id' /php-5.3.2/ext/sqlite3/sqlite3.c:123: undefined reference to `core_globals_id' The undefined reference comes up for several things.

  • Is there a Firefox or Chrome plugin, or a standalone program, for monitoring site usage and search queries?

    - by Leigh Caldwell
    I'm running some research on how people search the web for specific types of information. I'd like to be able to set them up with a laptop and browser and then record a history of what they search for and what sites they visit. A Firefox or Chrome plugin would be ideal, but a standalone program is fine too. It doesn't need to be free, just quick and reliable. It doesn't need to be a general PC monitoring program (though that would be OK too) - it's only Web usage I need to track. I've found a few on the Web but am not sure which ones to trust. Your recommendations would be much appreciated.

    All, I am using PHP 5.3.1 under Ubuntu and using the SOAP package. I am getting the following errors when I include SOAP/Client.php. Any one knows how to get this working? Thanks Deprecated: Assigning the return value of new by reference is deprecated in /opt/lampp/lib/php/SOAP/WSDL.php on line 214 Deprecated: Assigning the return value of new by reference is deprecated in /opt/lampp/lib/php/SOAP/WSDL.php on line 791 Deprecated: Assigning the return value of new by reference is deprecated in /opt/lampp/lib/php/SOAP/WSDL.php on line 1159 Deprecated: Assigning the return value of new by reference is deprecated in /opt/lampp/lib/php/SOAP/WSDL.php on line 1685 Deprecated: Assigning the return value of new by reference is deprecated in /opt/lampp/lib/php/HTTP/Request.php on line 228 Deprecated: Assigning the return value of new by reference is deprecated in /opt/lampp/lib/php/HTTP/Request.php on line 324 Deprecated: Assigning the return value of new by reference is deprecated in /opt/lampp/lib/php/HTTP/Request.php on line 602 Deprecated: Assigning the return value of new by reference is deprecated in /opt/lampp/lib/php/HTTP/Request.php on line 621 Strict Standards: Redefining already defined constructor for class Net_URL in /opt/lampp/lib/php/Net/URL.php on line 122

  • Is this error caused by a 64-bit library being accessed by a Java program running in a 32-bit JVM?

    - by Mike
    I'm trying to create a simple Java app that uses JNI to call some native functions. I've followed the examples in the JNI Programming Guide and can't seem to get them to work. I have the following Hello World program, written in Java: class HelloWorld { private native void print(); public static void main(String [] args) { new HelloWorld().print(); } static { System.load("/home/mike/Desktop/libHelloWorld.so"); } } I compile it using javac HelloWorld.java, just like normal. Then I run javah -jni HelloWorld, and finally the following: gcc34 -shared -fpic -o libHelloWorld.so -I/<path to JDK>/include -I/<path to JDK>/include/linux HelloWorld.c gcc34 is the name of the GCC program on my machine here at work (I don't control that) and I obviously place the real path to the JDK in that command. When I run my program, using the standard java HelloWorld, I get an error saying the following: Exception in thread "main" java.lang.UnsatisfiedLinkError: /home/mike/Desktop/libHelloWorld.so: /home/mike/Desktop/libHelloWorld.so: wrong ELF class: ELFCLASS64 (Possible causes: architecture word width mismatch) at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1778) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1674) at java.lang.Runtime.load0(Runtime.java:770) at java.lang.System.load(System.java:1003) at HelloWorld.<clinit>(HelloWorld.java:8) Could not find the main class: HelloWorld. Program will exit. I know I'm running a 32-bit JVM (and unfortunately, as of right now, I'm not allowed to get a 64-bit JVM). I tried telling GCC to compile in 32-bit mode using the "-m32" option, but we don't have (and again, can't get) what we need for that. Does this sound like a 32/64-bit conflict or something else?

  • IEnumerable<T>.Concat -- A replacement that can work without changing the reference?

    - by Earlz
    Hello, I've recently been bitten by the (way too commmon in my opinion) gotcha of Concat returns it's result, rather than appending to the list itself. For instance. List<Control> mylist=new List<Control>; //.... after adding Controls into mylist MyPanel.Controls.Concat(mylist); //This will not affect MyPanel.Controls at all. MyPanel.Controls=MyPanel.Controls.Concat(mylist); //This is what is needed, but the Controls reference can not be reassigned (for good reason) So is there some other way of combining two lists that will work when the collection reference is read-only? Is the only way to do this with a foreach? foreach(var item in mylist){ MyPanel.Controls.Add(item); } Is there a better way without the foreach?
