• Load page, wait, log any JavaScript errors to file?

  - by David

  I would like to check a large number of HTML files with inline JavaScript for JavaScript errors. What I'm envisioning doing is this: Script a browser to load a given page, wait a few seconds, and finally check the browser logs. I'm unsure though both on how to script a browser to load a given page and on how to access the JavaScript error log. I think the type of errors I'm worried about should show up in any modern browser so I would just go with whatever makes it most convenient. I'd be working either under Mac OS X or Linux. Anybody already tackle a similar problem? I've thought a bit about hacking something together based on a unit testing framework -- generate a trivial (assertTrue(true)) test for each page and rely on the errors making it fail -- but I'm hoping for something more elegant. Thank you.

• Linking Libraries in Xcode

  - by Dan

  Hey all, I'm using a powerbook (osx 10.5) and recently downloaded and installed FFTW 3.2 (link text). I've been able to compile and run some simple programs based on the online tutorial using the terminal: g++ main.cpp -lfftw3 -lm however, I can't get the same program to compile in Xcode. I get a linking error, "symbol(s) not found". There is a file called libfftw3.a in /usr/local/lib. How can this be linked? Furthermore, apparently the libraries have to be linked in a particular order, i.e. see: link text thanks for any help

• Clojure: Avoiding stack overflow in Sieve of Erathosthene?

  - by nixx

  Here's my implementation of Sieve of Erathosthene in Clojure (based on SICP lesson on streams): (defn nats-from [n] (iterate inc n)) (defn divide? [p q] (zero? (rem q p))) (defn sieve [stream] (lazy-seq (cons (first stream) (sieve (remove #(divide? (first stream) %) (rest stream)))))) (def primes (sieve (nats-from 2))) Now, it's all OK when i take first 100 primes: (take 100 primes) But, if i try to take first 1000 primes, program breaks because of stack overflow. I'm wondering if is it possible to change somehow function sieve to become tail-recursive and, still, to preserve "streamnes" of algorithm? Any help???

• Usage of closures with multiple arguments in swift

  - by Nilzone-

  This question is largely based on this one: Link The main difference being that I want to pass in arguments to the closure as well. Say I have something like this: func someFunctionThatTakesAClosure(completionClosure: (venues: Dictionary<String, AnyObject>, error: NSError) -> ()) { // function body goes here var error: NSError? let responseDictionary: Dictionary<String, AnyObject> = ["test" : "test2"] completionClosure(venues: responseDictionary, error: error!) } No error here. But when I call this function in my main view controller I have tried several ways but all of the result in different errors: venueService.someFunctionThatTakesAClosure(completionClosure(venues: Dictionary<String, AnyObject>, error: NSError){ }) or like this: venueService.someFunctionThatTakesAClosure((venues: Dictionary<String, AnyObject>, error: NSError){ }) or even like this: venueService.someFunctionThatTakesAClosure(completionClosure: (venues: Dictionary<String, AnyObject>, error: NSError) -> (){ }); I'm probably just way tired, but any help would be greatly appreciated!

• serial port close hangs in compact frame work 3.5

  - by ananda

  I have developed the application for windows mobile 5.0 and .net compact framework 2.0 sp2. This application communicates to the hardware device using serial port. This application works fine in windows mobile 5.0 based PDAs. I have handled data received event to get the data from serial port. But when I run my application on windows mobile 6.1 and .net compact framework 3.5, my application hangs on serial port close API call. There are many workarounds mentioned in the .net compact framework blog like (closing the com port on different thread, opening the port in the beginning of the application and close once application exists, polling for data instead of event handling), but nothing is working consistently.

• Any form autofill for 'Developers'?

  - by Majid

  Hi all, I have looked at some autofills for Firefox. But they are not designed with the developers' needs in mind. General internet surfers will need a tool to fill in many different forms with constant values for each form. Developers need exactly the opposite, when you want to test a part of your app you'll need to fill a single (or a couple of) forms many times with different (but valid and sensible) data. So, does such a thing exist? An autofill to fill form inputs based on perhaps a class name (email, password, address, url, ...)? I strongly feel if it doesn't exist someone should roll up their sleeves and make one! I for one will put in my share if some others want to team up. But right now, I am desperately in need of one if it exists

• Wpf stop routing event when MessageBox appear?

  - by yossharel

  Hi all, I've PreviewMouseDown event on TreeView in order to determine if user can select other item based on some logic. If the current item data changed, will appear MessageBox that asks the user if he want to discard the changes. if user press YES , I set e.Handled = false; to enable the new selection. and if user press NO, I set e.Handled = true; to cancel the new selection. The problem is that although I set e.Handled = false , the event stop and no selection event occurs on TreeView. Someone has solution for that? Thanks in advance!

• Operating System for first production windows server code?

  - by Unkwntech

  I'm getting ready to purchase a server for me to deploy my first windows based (C# .NET) application but I'm not familiar with using windows for hosted applications. I have the choice of the following versions of windows: Windows Server 2003 Windows Server 2003 Web Windows Server 2003 Enterprise Windows Server 2008 Windows Server 2008 Web Windows Server 2008 Enterprise Would one of these be better for deploying a C# .NET application? EDIT: There will be 3 applications deployed but each will basically be the same, they will be services that are driven from data being brought in from a website that will likely run on the same server. http://www.microsoft.com/windowsserver2008/en/us/compare-roles.aspx

• How to make a legacy webapp spring aware at the container level for bean autowire into Servlets?

  - by Pete

  We have a legacy web application (not Spring based) and are looking for best practices to autowire some newer Spring configured (thread safe) service beans into instance variables in several of the legacy servlets. Rewriting every servlet to Spring MVC is out of scope. For testability, we do not want any Spring specific bean lookup code in the Servlets to look up beans by name or similar. Note that we are not concerned about web specific bean scopes such as session or request; all services are singleton scope. Below shows relevant code snippet MyServlet extends LegacyServletSuperclass { private MyThreadSafeServiceBean wantThisToBeAutowiredBySpring; .... }

• How to leverage Spring Integration in a real-world JMS distributed architecture?

  - by ngeek

  For the following scenario I am looking for your advices and tips on best practices: In a distributed (mainly Java-based) system with: many (different) client applications (web-app, command-line tools, REST API) a central JMS message broker (currently in favor of using ActiveMQ) multiple stand-alone processing nodes (running on multiple remote machines, computing expensive operations of different types as specified by the JMS message payload) How would one best apply the JMS support provided by the Spring Integration framework to decouple the clients from the worker nodes? When reading through the reference documentation and some very first experiments it looks like the configuration of an JMS inbound adapter inherently require to use a subscriber, which in a decoupled scenario does not exist. Small side note: communication should happen via JMS text messages (using a JSON data structure for future extensibility).

• Is there a standard Cyclic Iterator in C++

  - by Hippicoder

  Based on the following question: Check if one string is a rotation of other string I was thinking of making a cyclic iterator type that takes a range, and would be able to solve the above problem like so: std::string s1 = "abc" ; std::string s2 = "bca" ; std::size_t n = 2; // number of cycles cyclic_iterator it(s2.begin(),s2.end(),n); cyclic_iterator end; if (std::search(it, end, s1.begin(),s1.end()) != end) { std::cout << "s1 is a rotation of s2" << std::endl; } My question, Is there already something like this available? I've check Boost and STL doesn't have one. I've got a simple hand-written one but would rather use an already made/tested implementation.

• HLSL How can one pass data between shaders / read existing colour value?

  - by RJFalconer

  Hello all, I have 2 HLSL ps2.0 shaders. Simplified, they are: Shader 1 Reads texture Outputs colour value based on this texture Shader 2 Needs to read in existing colour (or have it passed in/read from a register) Outputs the final colour which is a function of the previous colour (They need to be different shaders as I've reached the maximum vertex-shader outputs for 1 shader) My problem is I cannot work out how Shader 2 can access the existing fragment/pixel colour. Is the only way for shaders to interact really just the alpha blending options? These aren't sufficient if I want to use the colour as input to my function.

• What is a Web Framework ? How does it compare with LAMP

  - by Nishant

  I started web development in LAMP/WAMP and it was logical to me . There is a Web Server program called Apache which does the networking part of setting up a service on port 80 ( common port ) . If the request is regular HTML it uses the HTTP headers to transport files .And if the request for the file is a PHP one , it has a mod_php with which Apache invokes the PHP interpreter to process the file and it gives back HTML which is again transferred as usual HTML . Now the question is what is a Web Framework ? I came across Python based website creation and there is Flask . What is a flask , how does it compare with LAMP . Further are DJango / Ruby on Rails different from flask ? Can someone answer me and also give some good places to read on these .Thanks for your answers in advance . Further is things like LAMP slower than the common FRAMEWORKS because they claimn easy deplyment fo web apps .

• Should I integrate FedEx or UPS into my Rails app?

  - by MikeH

  I'm working on integrating a shipping solution into a Rails ecommerce app. We're only going to use one shipping provider. So the question is: FedEx or UPS? I'm wondering what Rails developers think about the tech side of this question. What do you think about the APIs, ease of integration, focus on developer's needs between FedEx and UPS? I was leaning towards FedEx, but from looking at the developers resources sections of both sites, it seems that UPS might be more developer friendly. Also, I'm going to be using Shopify's active_shipping gem: http://github.com/Shopify/active_shipping And I also based my app off the Spree Ecommerce solution, but I don't think that's particularly relevant to the question. Spree wrote a wrapper to integrate active_shipping with the Spree system. Thanks.

• What is more interesting or powerful: Curry/Mercury/Lambda-Prolog/your suggestion.

  - by Bubba88

  Hi! I would like to ask you about what formal system could be more interesting to implement from scratch/reverse engineer. I've looked through some existing and rather open (open in the sense of free/open-source) projects of logical/declarative programming systems. I've decided to make up something similar in my free time, or at least to catch the general idea of implementation. It would be great if some of these systems would provide most of the expressive power and conciseness of modern academic investigations in logic and it's relation with computational models. What would you recommend to study at least at the conceptual level? For example, Lambda-Prolog is interesting particularly because it allows for higher order relations, but AFAIK (I might really be mistaken :)) is based on intuitionist logic and therefore lack the excluded-middle principle; that's generally a disatvantage for me.. I would also welcome any suggestions about modern logical programming systems which are less popular but more expressive/powerful. I guess, this question will need refactoring, but thank you in advance! :)

• How to configure grails and shiro to mark cookies secure?

  - by j4y

  I'm using Grails 2.2.4 with the Shiro plugin (v1.1.4) and would like to mark the cookies as secure so the session information won't be sent over http. This is the attribute I want to set: securityManager.sessionManager.sessionIdCookie.secure = true The shiro source says to use the Grails bean property override mechanism, which is grails-app/conf/spring/resources.groovy How can I override just the one setting? // If the legacy 'security.shiro.filter.config' option is set, // use our custom INI-based filter... if (application.config.security.shiro.filter.config) { log.warn "security.shiro.filter.config option is deprecated. Use Grails' bean property override mechanism instead." 'filter-class'('org.apache.shiro.grails.LegacyShiroFilter') 'init-param' { 'param-name'('securityManagerBeanName') 'param-value'('shiroSecurityManager') }

• Editing Multiple files in vi with Wildcards

  - by Alan Storm

  When using the programmers text editor vi, I'll often using a wildcard search to be lazy about the file I want to edit vi ThisIsAReallLongFi*.txt When this matches a single file it works great. However, if it matches multiple files vi does something weird. First, it opens the first file for editing Second, when I :wq out of the file, I get a message the bottom of the terminal that looks like this E173: 4 more files to edit Hit ENTER or type command to continue When I hit enter, it returns me to edit mode in the file I was just in. The behavior I'd expect here would be that vi would move on to the next file to edit. So, What's the logic behind vi's behavior here Is there a way to move on and edit the next file that's been matched? And yes, I know about tab completion, this question is based on curiosity and wanting to understand the shell better.

• Incorporate Wordpress into Kohana 3

  - by alex

  I now need to make a Kohana 3 site have a Wordpress blog. I've seen Kerkness' Kohana For Wordpress, but it seems to be the opposite of what I want. Here are the options I have thought of Style a template to look exactly like the Kohana site (time consuming, non DRY and may not work) Include the blog within an iframe (ugly as all hell) cURL the Wordpress pages in. This of course means I will need to create layers between comment posting, etc, which sounds like too much work. Is there any way I can include a Wordpress blog within an existing Kohana application? Do you have any suggestions? Thanks Update Forgot to mention I have already programmed a model in Kohana to open pages based on their slug. Now I want to put blog content in there, and have the comments and other bits work. I also have installed WP e-Commerce and am wondering if there is any chance I can get that to work.

• iOS 6&7: Storyboard, master detail ViewController when detailViewController is dynamic

  - by Cam

  I'm building an app for iPhone, I want to use storyboard in XCode to do a simple selection from a tableView (let's call it master table view controller with couple rows) then through navigation it goes to next page and shows a detail view for that selection. I have in my code a base class representing my detailViewController, and have 2-3 driver classes of this base class representing what I want to show in detail view controller in second page, can someone give me an idea how to set destination viewController (detailViewController) dynamically to one of my child class based on the selected row in master view controller using storyboard? Usually you assign a class to destination class in storyboard for your detail view controller with using segue, but since my destination class could be a different (child class) how you set this in storyboard? Thank you, Kam

• What messaging technologies in windows-ce for guaranteed msg delivery?

  - by Aidanapword

  We are building a windows-ce (6.0R3) based device that requires guaranteed and audit-ready message delivery (including store & forward) up to and down from the cloud. I have been looking for choices beyond: MSMQ a proprietary solution (what our prototype device is using) AMQP (I have not found any RabbitMQ clients for CE, by example) ... are there any others? We will be transporting sensitive data (who isn't?!?!) over a public network, and large scale options are required. Anything running on an embedded device will be performance sensitive too.

• Palm webOS CSS Targeting Hack?

  - by Tom

  Although it is not good practice, I am looking for a CSS hack to target Palm webOS. The problem is that Safari 3+ is awesome, and I can do some things like gradient background animations on text, but only in Safari. Right now I use @media screen and (-webkit-min-device-pixel-ratio:0) {} and it works like a charm, no Opera, Firefox, or whatever, because if I set the background to the image as I do in Safari they will all be ruined. But Palm's browser is based on webkit, and it uses the rules inside, and Palm's browser doesn't support text backgrounds so all I get is the image moving, no text. I would prefer a CSS hack, but if need be a Javascript one will do.

• What web UI framework is most suitable for building dynamic pages / forms?

  - by waxwing

  Hello, We are at a stage where we are considering different Web UI frameworks (most likely component based ones such as GWT, JSF, Wicket, Vaadin, etc). One of the main use cases / constraints is that it must support generating dynamic pages. I.e., the page/form layout and components is stored in a database and is changeable at runtime, and from this pages are generated. We are also going to write static layouts, but that is not the main focus of this question. I thought maybe the user community here can share experiences of different frameworks in this context. Are there differences in ease of implementation and what is suitable?

• Determine if a day of week and time fall in a custom weekend period

  - by Y Low

  I've been trying to come up with a method, that given a day of week and time of day, it will return if it falls under a custom weekend period. The weekend period is saved in 4 variables as follows: The day of week when it starts (0-6) The time of day when it starts (0-23) The day of week when it ends (0-6) The time of day when it ends (0-23) Based on these fields, the weekend period can be anything the user selected (even if it is well beyond a regular weekend) I've been banging this one for awhile but to no avail. I'm trying this in delphi but any language will do, as I'm looking for the algorithm and not the implementation.

• Windows Sharepoint Service (WSS) 3.0 search Issue

  - by dewacorp.alliances

  Based on this http://servergrrl.blogspot.com/2008/02/how-to-use-wss-30-to-search-more-than.html blog, I've created a domain account for testing and sets the permission at the side level as well as Document Library to allow specific user (DOMAIN/TestUser1) allow accessing this folder. Now, it's interesting that the user can see the document by drilling though BUT it won't be able to search and the document couldn't find it. But if I tested with the site owner (both primary and secondary), it works nicely. What did I do wrong then? It must be related on permission but I cound't work out what it is. BTW ... I am using WSS not MOSS 2007. Thanks

• NHibernate filters don't work with Session.Get

  - by Khash

  I'm trying to implement a Soft-deletable repository. Usually this can be easily done with a Delete Event listener. To filter out the deleted entities, I can add a Where attribute to my class mapping. However, I also need to implement two more methods in the repository for this entity: Restore and Purge. Restore will "undelete" entities and Purge will hard-delete them. This means I can't use Where attribute (since it block out soft-deleted entities to any access) I tried using filters instead. I can create a filter and enable or disable it within session to achieve the same result. But the problem is filters don't have any effect on Session.Get method (they only affect ICriteria based access). Any ideas as to how solve this problem? Thanks
