  • Rails Devise: How to access sign up page after signed in?

    - by Junior rails programmer
    hi All, I am new with rails and i am using "devise" gem for authentication purposes. At first i add a new user through default sign up page (E.g./users/sign_up) Then, i made "sign_up" page only available to signed_in users by following instructions from Devise before filter that prevents access to "new_user_registration_path" unless user is signed-in Now, after sign in process when i try open sign up page it always directs me to root_path! How can i access sign up page? My "roots.rb" file as follows: Example::Application.routes.draw do devise_for :users, :controllers => { :registrations => 'registrations'} resources :companies resources :orders resources :customers root :to => "welcome#index" end Thank you all!

  • Reverse massive text file in Java

    - by DanJanson
    What would be the best approach to reverse a large text file that is uploaded asynchronously to a servlet that reverses this file in a scalable and efficient way? text file can be massive (gigabytes long) can assume mulitple server/clustered environment to do this in a distributed manner. open source libraries are encouraged to consider I was thinking of using Java NIO to treat file as an array on disk (so that I don't have to treat the file as a string buffer in memory). Also, I am thinking of using MapReduce to break up the file and process it in separate machines. Any input is appreciated. Thanks. Daniel

  • Problem with an application on USB, a tricky one

    - by rajivpradeep
    I have this application on USB built in VS 2008, on win7 , the USb has two partitions one hidden and other normal one, when i run the application on normal part , it has to swap the part to hidden and run the applications present in hidden part. When i run the application in normal part from USB , the memory swaps but the applications in hidden part are not run. but i can see the application running in Task manager. when i copy the application and run it from the desktop, the application works seamlessly, without any glitch. I guess some thing is holding the application process when run from USB, i cannot safe eject the USB too. CAn some one give me a clue as to what can be done to resolve. Also the application works well on Windows 7 as expected. The problem is on XP

  • Best way to daemonize Java application on Linux

    - by SyBer
    Hi. While I found this question being answered here on SW several times, I didn't find a concluding answer what is the best approach. I'm not looking to use any external wrapper, as I found them launching the java process under a nice level lower then themselves which potentially lowers the performance, so it seems only the shell methods are left. I so far found 3 different shell methods: start-stop-daemon RedHat daemon init.d function nohup on start / disown after start What you people are using, and can recommend as the most reliable method? Thanks.

    - by Eppo
    I have a 2 fragment layout, on the left fragment, i have a list of the different table names, on the right, i open up a different table depending on what is clicked on the right fragment. my intention, is that the first list item is clicked, then values will be entered on the table, next the second list item is clicked, the next table opens up and those values are entered. what would be the best way to store the values of the results entered in the editboxes, so i can process them all at once? I'm sure i can use onPause to save them all, but would that be the best way? Thanks

    Hello, For my site, I would like to give new users the option to invite all of their Gmail contacts to join. What is the basic step-by-step process to set this up?

I would also like to give them the option to invite their Gmail contacts anytime they want.

  • Possible to map a new file extension to an existing handler in ASP.NET?

    - by Dave
    I have a scenario where my application is going to be publishing services that are consumed by both PC's and mobile devices, and I have a HTTPModule that I want to only perform work on only the mobile requests. So I thought the best way of doing this was to point the mobile requests to a different file extension and have the HTTPModule decide to process only if the request targets this new extension. I don't need a custom HTTPHandler for the new extension; I want to program the services like a normal .ASMX service, just with a different extension. First, can I do this? If so, how do I do it so that requests to my new extension are handled just like .ASMX requests? Second, is this the right approach? Am I going about separating and managing the mobile vs. PC requests the wrong way? Thanks, Dave

  • Drop down menus and pathetic art of styling

    - by fmz
    Sorry folks, I must be brain-dead or something but I can't get the styling on these drop-down menus to cooperate. I have the color and the font right, but I have unwanted spaces between the list elements and the a and the a:hover sizes should be the same. I would appreciate some help getting this to work correctly. Here is the page Here is the html: <ul class="dropdown"> <li><a href="#" id="home">Home</a></li> <li><a href="#" id="about">About Us</a> <ul class="sub-menu"> <li><a href="#">Our History</a></li> <li><a href="#">Our Process</a></li> <li><a href="#">Portfolio</a></li> <li><a href="#">Financing</a></li> <li><a href="#">Testimonials</a></li> <li><a href="#">Subcontractors</a></li> </ul> </li> <li><a href="#" id="personal">Personal Banking</a></li> <li><a href="#" id="commercial">Commercial Banking</a></li> <li><a href="#" id="service">Customer Service</a> <ul class="sub-menu"> <li><a href="#">Our History</a></li> <li><a href="#">Our Process</a></li> <li><a href="#">Portfolio</a></li> <li><a href="#">Financing</a></li> <li><a href="#">Testimonials</a></li> <li><a href="#">Subcontractors</a></li> </ul> </li> <li><a href="#" id="investors">Investor Relations</a></li> <li><a href="#" id="contact">Contact Us</a></li> Here is the CSS: ul.dropdown { position: relative; background: #4e8997; height: 40px; padding-left: 5px; } ul.dropdown li { float: left; zoom: 1; } ul.dropdown li a ul.dropdown li a:visited { display: block; margin-top: 5px; padding: .5em .6em; line-height: 16px; color: #fff; font: bold 14px "Helvetica Neue", Arial, Helvetica, Geneva, sans-serif; text-transform: uppercase; border: none; } ul.dropdown a:hover { background-color: #c29c5d; color: #fff; } ul.dropdown a:active { background-color: #c29c5d; color: #fff; } /* LEVEL TWO */ ul.dropdown ul { padding-left: 0; width: 200px; display: none; top:36px; margin-left: 0; position: absolute; } ul.dropdown ul li { font: 10px "Helvetica Neue", Arial, Helvetica, Geneva, sans-serif; border-bottom: 1px solid #ccc; display: block; margin: 0; padding: 0; float: none; color: #fff; background-color: #c29c5d; } ul.dropdown ul li a:link { display: block; font-size: 10px; width: 188px; height: 16px; } ul.dropdown ul li a:hover { background-color: #a2834d; color: #fff; } Thanks!

  • How to handle lifecycle of dynamically allocated data in Windows messages?

    - by nang
    Simple task: Send a windows message with dynamically allocated data, e.g. an arbitrary length string. How would you manage the responsibility to free this data? The receiver(s) of the windows message could be responsible to free this data. But: How can you guarantee that all messages will actually be received and thus the linked data will be freed? Imagine the situation that the receiver is shutting down, so it won't process it's message queue any more. However, the message queue still exists (for some time) and can still accept messages, which won't be processed any more. Thanks!

  • tomcat multithreading problem

    - by jutky
    Hi all I'm writing a java application that runs in Tomcat, on a multi-core hardware. The application executes an algorithm and returns the answer to the user. The problem is that even when I run two requests simultaneously, the tomcat process uses at most one CPU core. As far as I understand each request in Tomcat is executed in separate thread, and JVM should run each thread on separate CPU core. What could be the problem that bounds the JVM or Tomcat to use no more than one core? Thanks in advance.

  • does a switch idiom make sense in this case?

    - by the ungoverned
    I'm writing a parser/handler for a network protocol; the protocol is predefined and I am writing an adapter, in python. In the process of decoding the incoming messages, I've been considering using the idiom I've seen suggested elsewhere for "switch" in python: use a hash table whose keys are the field you want to match on (a string in this case) and whose values are callable expressions: self.switchTab = { 'N': self.handleN, 'M': self.handleM, ... } Where self.handleN, etc., are methods on the current class. The actual switch looks like this: self.switchTab[selector]() According to some profiling I've done with cProfile (and Python 2.5.2) this is actually a little bit faster than a chain of if..elif... statements. My question is, do folks think this is a reasonable choice? I can't imagine that re-framing this in terms of objects and polymorphism would be as fast, and I think the code looks reasonably clear to a reader.

  • Is there a chance that sending an email via a thread could ever fail to complete?

    - by Benjamin Dell
    I have a project where I send a couple of emails via a seperet thread, to speed up the process for the end-user. It works successfully, but i was just wondering whether there were any potfalls that i might not have considered? My greatest fear is that the user clicks a button, it says that the message has been sent (as it will have been sent to the thread for sending) but for some reason the thread might fail to send it. Are there any situations where a thread could be aborted prematurely? Please note, that i am not talking about network outages or obvious issues with an email recipient not existing. For simplicites sake please assume that the connect is up, the mail server alive and the recipient valid. Is it possible, for example, for the thread to abort prematurely if the user kills the browser before the thread has completed? This might be a silly question, but i just wanted to make sure i knew the full ramifications of using a thread in this manner. Thanks, in advance, for your help.

  • Adding Message Part dynamically in Receive Pipeline

    - by Sean
    Hello, I tried to create a custom pipeline component that takes a message and attaches additional another part dynamically (during Disassemble stage). I haven't set up a send port, so that I can see what BizTalk is trying to process. I can see only the body part, the additional part doesn't show up. This is the code I used: var part = pc.GetMessageFactory().CreateMessagePart(); part.Data = new MemoryStream(new byte[] {1, 2, 3, 4, 5}); inmsg.AddPart("another_part", part, false); Thank you.

  • .NET WebService IPC - Should it be done to minimise some expensive operations?

    - by Kyle
    I'm looking at a few different approaches to a problem: Client requests work, some stuff gets done, and a result (ok/error) is returned. A .NET web service definitely seems like the way to go, my only issue is that the "stuff" will involve building up and tearing down a session for each request. Does abstracting the "stuff" out to an app (which would keep a single session active, and process the request from the web service) seem like the right way to go? (and if so, what communication method) The work time is negligible, my concern is the hammering the transaction servers in question will probably get if I create/drop a session for each job. Is some form of IPC or socket based communication a feasible solution here? Thoughts/comments/experiences much appreciated. Edit: After a bit more research, it seems like hosting a WCF service in a Windows Service is probably a better way to go...

  • Function testing on Netbeans 6.8

    - by ron
    While not a torrent, but some articles can be found on the net about function testing (particularly http://blogs.sun.com/geertjan/entry/gui_testing_on_the_netbeans). However the tools mentioned by them do not seem to be maintained, or don't have a plugin working with the most recent version of Netbeans (6.8). Do you have any function test setup for GUI? What is your level of integration into the development process (IDE integration, ant, etc). Additional candy is that Netbeans is not only the IDE, but the GUI app is also developed for Netbeans 6.8 Platform (so I'm mainly interested in GUI testing NB-platform apps, but tips for any Swing apps in general would be a help too).

  • check external website registration

    - by Arsenal
    Hi, I'm trying to create a PHP based game where you have to do all sorts of simple but un-obvious tasks in order to progress to the next level (eg. refresh browser, press keyboard combination, ...) Kinda like the game "this is the only level" (if anyone has ever heard of it) Now I was thinking: Would it be possible to create a level where they'd have to sign up at a different page in order to progress to the next level? So say for example they need to sign up to goal.com and if they're signed up they proceed to the next level. The page would need to constantly check if the signup process on the other site is completed. Is this even possbible? And if so, any thoughts on how? Thanks!

  • Sending bulk notification emails without blocking

    - by FreshCode
    For my client's custom-built CRM, I want users (technicians) to be notified of changes to marked cases via email. This warrants a simple subscription mapping table between users and cases and automated emails to be sent every time a change is made to a case from within the logging method. How do I send 10-100 emails to subscribed users without bogging down my logging method? My SMTP server is on a peer on my LAN, so sends should be quick, but ideally this should be handled by an external queuing process. I can have a cron job send any outstanding emails every 10 minutes, but for this specific client cases are quite time-sensitive and instant notification (as instant as email can be) would be great. How can I send bulk notification emails from within ASP.NET MVC without bogging down my logging method?

  • Will PHP Die In Web Page Development World?

    - by Morgan Cheng
    I know that PHP is still the most popular web programming language in the world. This question just want to bring some of my concerns about PHP. PHP is naturally bound to C10K problem. Since PHP (generally run in Apache) cannot be event-driven or asynchronous, each HTTP request will occupy at least one thread or process. This makes it resistant to be more scalable. Currently, a lot of web sites (like Facebook) with high performance and scalability still depends on PHP in their front end servers. I suppose it is due to legacy reason. Is it possible that PHP will be replaced by language more suitable for C10K?

  • Checking status after wait()

    - by Helper Method
    After creating a child process and exiting it immediately (_exit()), I want to perform a wait and check the status. Now I wonder if in the 'else' branch of the if/else construct I also need to check for WIFSIGNALED. As far as I understand, if I perform a wait, a) an error could have occured (-1), the child could have terminated normally by an (exit() or _exit()), or it could have been terminated by a signal, so the check could be omitted, right? //remainder omitted int status; pid_t t_pid = wait(&status); if (t_pid == -1) { perror("wait"); exit(EXIT_FAILURE); } if (WIFEXITED(status)) { printf("child terminated normally, status = %d\n", WEXITSTATUS(status) ); } else { // <-- do it have to check for WIFSIGNALED() here? printf("child was terminated by a signal, signum = %d\n", WTERMSIG(status) ); }

  • Best tools / formats for documenting XML API?

    - by ivant
    We are developing XML over HTTP service and we need a way to document the XML interface. Our supported XMLs generally are subsets of some industry standard XML API, which unfortunately lacks any good documentation. It has XSDs though with some annotations, so we use this go generate the initial documentation and then remove the unsupported parts and refine the result. But this process is tedious and the results aren't at all great. Any suggestion about documentation formats and tools? I prefer to have HTML output and possibly more, e.g. PDF. Oh, and we are mixed Linux and Windows shop, so the tools should work well on both.

  • Mock a void method which change the input value

    - by Kar
    Hi, How could I mock a void method with parameters and change the value parameters? My void method looks like this: public interface IFoo { void GetValue(int x, object y) // takes x and do something then access another class to get the value of y } I prepared a delegate class: private delegate void GetValueDelegate(int x, object y); private void GetValue(int x, object y) { // process x // prepare a new object obj if (y == null) y = new Object(); if (//some checks) y = obj; } I wrote something like this: Expect.Call(delegate {x.GetValue(5, null);}).Do (new GetValueDelegate(GetValue)).IgnoreArguments().Repeat.Any(); But seems like it's not working. Any clue on what could be wrong?

  • vb.net auto detect dependency files for wix 3.7

    - by Khan
    I am in the process of learning WIX all thanks to MS for removing such a nice tool (vdproj) from the latest versions of visual studio. I have come to know that I can add my files (and dlls) to distribute in WIX using that tag. It is OK. But in vdproj it was very easy to add all files. I just need to right click in file view, and select 'add project output'. This was enough to add dozen of files that were required for my application. In visual studio 2012, and using WIX 3.7, what options do I have to automatically list all those dlls that are required by my application?

  • Using Durable Services for saving wcf instances

    - by miker169
    I am currently creating a service which connects to a DAL and that can run a few stored procedures, one of the issues I am facing is that for certain times of the month, we can't update the database, (at the moment this is done manually. This is done via the user adding a note to their calendar) But I would like to automate this process, one of the possible solutions I can think of using is a durable service. When the date is lets say the 1st of the month, the Update/Insert/Delete instances can get saved to a database, and then ran after that date in a batch. Is this the intended use of durable services ? Is there a better route I could possibly take ?

  • POS Desktop Application using DB or Localfiles ? using WPF

    - by Panindra
    I am planning to build a POS Application for my shop. I have enough knowledge to build the application using DB and also using local files( system.IO - binary files ) to store and access the data for my application. But , i have no deployment experience and confused in choosing data storing option. Database using MDF may be good option ( may ease plenty of coding ) but i don't want to have SQL server on my desktop. as i am using WPF for building , my concern is that my application may get slow due to server response and design rendering of WPF. Then i tried to use only local data (binary files) to store the data and retrive using class and objects. but this coding is taking lot of time , so in the middle of the process i struck in the dilemma of going back to Database . Please help , for performance wise whic one is better . and in Practical World ,in professional applications which one is widely using .. please give suggestions ..

  • How to make Mac OS X CrashReporter invoke debugger?

    - by StasM
    I have an appache module on Mac OS X that produces random crashes. I can reproduce these crashes with certain sequence of actions, and these crashes produce Crash Reporter dialog "httpd quit unexpectedly". Is there a way to cause Crash Reporter launch debugger (xcode, gdb, anything) instead of just displaying the backtrace? I've tried running httpd under gdb with httpd -X but the crash doesn't happen then - it happens only if many httpd's are running at once, and I found no way to attach gdb to all of them at once. So I was hoping maybe I can cause CrashReporter to attach the debugger when specific process crashes - is there a way to do it?
