  • Refresh backend in GWT development

    - by T.K.
    I am developing a GWT application that uses EJB and other Java EE 6 technology as the backend. I am currently using the GWT 2.0 plugin for Safari. When I change my GWT client side code and save in my IDE (NetBeans), all that's required is a simple reload in the browser for the changes to become active. That works great! However, often I work on the server-side (the EJBs, GWT server code, etc) and then something in on the GWT client side. Any changes done to the server-side do not appear to incrementally deploy to the Glassfish V3 server. Currently I close the GWT Development Mode application, and then recompile the EJBs, and then go back into GWT Development mode. That is tedious. Any better way of doing this? I tried the "deploy on save" option in NetBeans but it does not seem to do the trick.

  • JavaScript distributed computing project

    - by Ben L.
    I made a website that does absolutely nothing, and I've proven to myself that people like to stay there - I've already logged 11+ hours worth of cumulative time on the page. My question is whether it would be possible (or practical) to use the website as a distributed computing site. My first impulse was to find out if there were any JavaScript distributed computing projects already active, so that I could put a piece of code on the page and be done. Unfortunately, all I could find was a big list of websites that thought it might be a cool idea. I'm thinking that I might want to start with something like integer factorization - in this case, RSA numbers. It would be easy for the server to check if an answer was correct (simply test for modulus equals zero), and also easy to implement. Is my idea feasible? Is there already a project out there that I can use?

  • How can I store all the properties of a class in an array of objects?

    - by Richard77
    Hello, Let's say I've a class myClass which has few properties, such as property1, property2, perperty3, etc. Now, I'd like to populate an array with each of those properties so that, I can access each of them through its index. Is there an automatic way of doing so? Here's an example from SportsStore (Pro ASPN.NET MVC/Steve Sanderson/Apress) on how to gather all the active controllers in the the 'Assembly'. var controllerTypes = from t in Assembly.GetExecutingAssembly().GetTypes() where typeof(IController).IsAssignableFrom(t) select t; foreach(Type t in controllerTypes) //Do something I wonder if there is some thing like the one above I can use to collect (only) properties of a class and store them in a array, no matter each one's type value (int, string, or custom type) I hope I was able to express myself clearly. Otherwise I can amend the text. Thanks for helping.

  • How can I replace jQuery Tools Scrollable bullets with numbers?

    - by Steven
    I'm using jQuery Tools for creating an article carousel. You can see in action with images here: http://flowplayer.org/tools/demos/scrollable/plugins/index.html The navigation code looks like this: <!-- wrapper for navigator elements --> <div class="navi"></div> And the plugin ads links like so: <!-- wrapper --> <div class="navi"> <a href="0" class="active"/> <a href="1" class=""/> <a href="2" class=""/> </div> The code to get it all started goes like this: $(".scrollable").scrollable({ circular: true, size: 1}).navigator(); My question is: How can I replace <a href="1" class=""/> with <a href="1" class=""> [1] </a> ?

  • MongoDB Schema Design - Real-time Chat

    - by Nick
    I'm starting a project which I think will be particularly suited to MongoDB due to the speed and scalability it affords. The module I'm currently interested in is to do with real-time chat. If I was to do this in a traditional RDBMS I'd split it out into: Channel (A channel has many users) User (A user has one channel but many messages) Message (A message has a user) The the purpose of this use case, I'd like to assume that there will be typically 5 channels active at one time, each handling at most 5 messages per second. Specific queries that need to be fast: Fetch new messages (based on an bookmark, time stamp maybe, or an incrementing counter?) Post a message to a channel Verify that a user can post in a channel Bearing in mind that the document limit with MongoDB is 4mb, how would you go about designing the schema? What would yours look like? Are there any gotchas I should watch out for?

  • How to enable i18n from within setup_app in websetup.py ?

    - by daniel
    From within the setup_app function (websetup.py) of a pylons i18n application, which is making use of a db, I was trying to initiate multilingual content to be inserted into the db. To do so the idea was something like: necessary imports here def setup_app(command, conf, vars): .... for lang in langs: set_lang(lang) content=model.Content() content.content=_('content') Session.add(content) Session.commit() Unfortunately it seems that it doesn't work. the set_lang code line is firing an exception as follows: File ".. i18n/translation.py", line 179, in set_lang translator = _get_translator(lang, **kwargs) File ".. i18n/translation.py", line 160, in _get_translator localedir = os.path.join(rootdir, 'i18n') File ".. /posixpath.py", line 67, in join elif path == '' or path.endswith('/'): AttributeError: 'NoneType' object has no attribute 'endswith' Actually I'm even not sure it could be possible launching i18n mechanisms from within this setup_app function without an active request object. Anyone has tried some trick on a similar story ?

  • how to get the top left coordinates of the screen with javascript on firefox

    - by artsince
    I have a <div> element with position: absolute and z-index something big. I would like to cover the entire screen with this div with javascript. This is what I do and it works: document.getElementById('mydiv').style.top = 0; document.getElementById('mydiv').style.left = 0; document.getElementById('mydiv').style.width = '100%'; document.getElementById('mydiv').style.height = '100%'; However, when I scroll down with long webpages, this code displays my div at the top of the page, so the div renders above the region I currently view. How can I change the top and left values so that my div always covers the active field I am viewing? I work on firefox 3.6.*. Thank you

  • Best Version control for lone developer

    - by Stephen
    I'm a lone developer at the moment; please share you experiences on what is a good VC setup for a lone developer. My constraints are; I work on multiple machines and need to keep them synced up Sometimes I work offline I'm currently using Subversion(just the client to a remote server), and that is working ok. I'm interested in mecurial and git DVCS, but none of their use-cases make sense to my situation. EDIT: I've migrated my active development to Fossil http://www.fossil-scm.org/ after trialing it with a client. I really like the features to autosync my repositories(reducing accidental forks), the documentation support(both wiki and embedded/versioned) that supports my need to document the code and the project in different spaces, the easy to configure issue tracker, nice access control, skinnable web interface and helpful community.

  • Test wordpress sites for SQL Injection on siteurl

    - by Scott B
    I have a client who's wordpress sites have gotten hacked twice by iframe scammers. Each time they've injected iframe code into the content of the sites. This last time, today, they simply changed the siteurl in wp_options to their iframe code. The result was obvious and appeared to simply botch the paths of the scripts that rely on I can't determine if its a password compromise (on FTP or WordPress itself) or a SQL injection to alter siteurl. Since the only thing that was altered is siteurl, I'm thinking perhaps SQL Injection. What are your thoughts? Any way to scan a site for potential SQL injection vulnerabilities? The only active plugins on the site are contact form 7 and google xml sitemaps.

  • In the java DBCP connection pool - what is an idle connection?

    - by Ravenor
    A colleague at work insists that a DBCP idle connection is a connection that has lain unused for 30 minutes. I believe a dbcp idle connection is a connection that is in the pool available to be borrowed, and an active connection is one that is borrowed. Looking through the code I found no reference to 30 minutes or other magic values and a cursory glance through the code for assuring minidle does not show any such logic. If he is correct can you please back that up with a code or documentation reference. For the complete answer I would like it answered for both DBCP 1.1 and 1.6.

  • No network packets sent immediately after quick physical disconnect and reconnect.

    - by Hans
    I am using Boost's ASIO libraries to establish a UDP connection to a remote server. To make sure the connection is active, every second a keep-alive message is sent to the server. I have noticed that if I unplug the network cable and reinsert it quickly, the first 2 or 3 keep-alive messages after the reinsert are never sent. I tested this by running wire-shark on the server. I have seen it take up to 5 seconds before the client starts sending out network traffic again. The client is running under Linux (2.6.2), if that helps.

  • Which places I could question about TFS, Visual Studio and ALM?

    - by afsharm
    Hi all, We are going to applying VSTS 2010 in our company. This includes Visual Studio, TFS, TFS Build and ALM. It's predictable that we would encounter a wave of new questions about their usage. But the problem is I don't know which places we could do questioning. StackOverflow is programming base question site and ServerFault is not very active. How do you think about? Which places and their advantages and disadvantages? afsharm

  • Mockito verify no more interactions but omit getters

    - by michael lucas
    Mockito api provides method: Mockito.verifyNoMoreInteractions(someMock); but is it possible in Mockito to declare that I don't want more interactions with a given mock with the exceptions of interactions with its getter methods? The simple scenario is the one in which I test that sut changes only certain properties of a given mock and lefts other properties untapped. In example I want to test that UserActivationService changes property Active on an instance of class User but does't do anything to properties like Role, Password, AccountBalance, etc. I'm open to criticism regarding my approach to the problem.

  • Generating Graph with 2 Y Values from Text File

    - by Joey jie
    Hi all, I have remade my original post as it was terribly formatted. Basically I would like some advice / tips on how to generate a line graph with 2 Y Axis (temperature and humidity) to display some information from my text file. It is contained in a textfile called temperaturedata.txt I have included a link to one of my posts from the JpGrapher forum only because it is able to display the code clearly. I understand that since it is JpGraph problem I shouldn't post here however the community here is a lot more supportive and active. Many thanks for all your help guys in advance! my code

  • Sketchflow component target parent state

    - by user186106
    Hi, I'm using Sketchflow in Expression Blend 4 RC (although this is relevant to Blend 3 too). I have a screen with a datagrid on it (MainScreen) and there's a "New" button. I have a component screen that has a generic form (GenericForm) and a "Save and close" button. I have two states on MainScreen: State1 (and default): GenericForm visibility set to Hidden State2: GenericForm visibility set to Visible The "New" button on MainScreen has: Active State = State2, meaning when the "New" button is pressed, it changes the state of MainScreen to State2 (where the GenericForm component is visible). My problem is that I cannot link the "Save and close" button on GenericForm to State1 on MainScreen. In effect I would like to be able to press "Save and close" and for the MainScreen to set its state to State1. Any ideas?

  • Question on Win32 LogonUser API and the Logon Type

    - by Lalit_M
    We have developed a ASP.NET web application and has implemented a custom authentication solution using active directory as the credentials store. Our front end application uses a normal login form to capture the user name and password and leverages the Win32 LogonUser method to authenticate the user’s credentials. When we are calling the LogonUser method, we are using the LOGON32_LOGON_NETWORK as the logon type. The issue we have found is that user profile folders are being created under the C:\Users folder of the web server. The folder seems to be created when a new user who has never logged on before is logging in for the first time. As the number of new users logging into the application grows, disk space is shrinking due to the large number of new user folders getting created. Has anyone seen this behavior with the Win32 LogonUser method? Does anyone know how to disable this behavior?

  • Open source political campaign management software?

    - by carolclarinet
    Does anyone know of any active open source projects working on political campaign management software? I looked on sourceforge but didn't see anything relevant from the queries "political", "politics", "donations", "campaign", or in the categories "accounting", "politics" or "voting". I'm involved with a political campaign that is currently paying out the nose for some horribly designed SaaS (whose Name i Guess i should Protect, ahem) to basically just keep track of donations people have made now, donations people have made in the past, donations people have pledged to make, contact information, the way they will likely vote, etc. It's a bit much to manage in spreadsheets, but doesn't seem like it's something complex enough that political campaigns should have to pay for (especially low-budget local ones). I'd love to help out if such a project exists, or start/revive one if it doesn't. Any hints, places to look, etc are much appreciated.

  • IIS 6.0 - ASP Error 0126 Include file not found

    - by André
    Hello, I have a Win Sever 2003 running IIS 6.0 which has only my main website on it and now I am trying to setup a test website which currently is an exact duplicate of the main site. When accessing my main site everything works fine, and has done for a long time. If I access the test site (through 'test.' subdomain) I get this error: Active Server Pages error 'ASP 0126' Include file not found /html/shop/asp/admin/inc/incWeeklySpecialswide3.asp, line 71 The include file '/html/asp/quickfindwithSuburbs31.asp' was not found. The file actually exists, and the paths are correct. I have enabled Parent Paths, replaced the include file path to the full path (http://foo.com/html/asp -etc.), removing the ' / ' at the start of the path and changing the code from ' include ' to ' virtual '. Thanks in advance.

  • Any exprience with Castle ActiveRecord?

    - by afsharm
    Hi all, I was searching for a light data access framework based on NHibernate. I needed simple CRUD and some simple HQL or LINQ-to-NHhibernate queries. Performance was not an important issue and applications which I'm working on have simple table structure but many tables. This data access framework is going to be used in a ASP.NET Webform application. Once a time I found S#harp architecture, but it was developed for ASP.NET MVC. Just today I found Castle ActiveRecord. But I'm wondering: If any one has any experience with it? Is it suitable for me? Should I consider any specific matter? What about its future? Is Castle ActiveRecord supposed to be developed and be active in coming years? Thanks in Advance

  • C# Button Text Unicode characters.

    - by Fossaw
    C# doesn't want to put Unicode characters on buttons. If I put \u2129 in the Text attribute of the button, the button displays the \u2129, not the Unicode character, (example - I chose 2129 because I could see it in the font currently active on the machine). I saw this question before, link text, but the question isn't really answered, just got around. I am working on applications which are going all over the world, and don't want to install all the fonts, more then "don't want", there are that many that I doubt the machine I am working on has sufficient disk space. Our overseas sales agents supply the Unicode character "numbers". Is there another way forward with this? As an aside, (curiosity), why does it not work?

  • Cobol: science and fiction

    - by user847
    There are a few threads about the relevance of the Cobol programming language on this forum, e.g. this thread links to a collection of them. What I am interested in here is a frequently repeated claim based on a study by Gartner from 1997: that there were around 200 billion lines of code in active use at that time! I would like to ask some questions to verify or falsify a couple of related points. My goal is to understand if this statement has any truth to it or if it is totally unrealistic. I apologize in advance for being a little verbose in presenting my line of thought and my own opinion on the things I am not sure about, but I think it might help to put things in context and thus highlight any wrong assumptions and conclusions I have made. Sometimes, the "200 billion lines" number is accompanied by the added claim that this corresponded to 80% of all programming code in any language in active use. Other times, the 80% merely refer to so-called "business code" (or some other vague phrase hinting that the reader is not to count mainstream software, embedded systems or anything else where Cobol is practically non-existent). In the following I assume that the code does not include double-counting of multiple installations of the same software (since that is cheating!). In particular in the time prior to the y2k problem, it has been noted that a lot of Cobol code is already 20 to 30 years old. That would mean it was written in the late 60ies and 70ies. At that time, the market leader was IBM with the IBM/370 mainframe. IBM has put up a historical announcement on his website quoting prices and availability. According to the sheet, prices are about one million dollars for machines with up to half a megabyte of memory. Question 1: How many mainframes have actually been sold? I have not found any numbers for those times; the latest numbers are for the year 2000, again by Gartner. :^( I would guess that the actual number is in the hundreds or the low thousands; if the market size was 50 billion in 2000 and the market has grown exponentially like any other technology, it might have been merely a few billions back in 1970. Since the IBM/370 was sold for twenty years, twenty times a few thousand will result in a couple of ten-thousands of machines (and that is pretty optimistic)! Question 2: How large were the programs in lines of code? I don't know how many bytes of machine code result from one line of source code on that architecture. But since the IBM/370 was a 32-bit machine, any address access must have used 4 bytes plus instruction (2, maybe 3 bytes for that?). If you count in operating system and data for the program, how many lines of code would have fit into the main memory of half a megabyte? Question 3: Was there no standard software? Did every single machine sold run a unique hand-coded system without any standard software? Seriously, even if every machine was programmed from scratch without any reuse of legacy code (wait ... didn't that violate one of the claims we started from to begin with???) we might have O(50,000 l.o.c./machine) * O(20,000 machines) = O(1,000,000,000 l.o.c.). That is still far, far, far away from 200 billion! Am I missing something obvious here? Question 4: How many programmers did we need to write 200 billion lines of code? I am really not sure about this one, but if we take an average of 10 l.o.c. per day, we would need 55 million man-years to achieve this! In the time-frame of 20 to 30 years this would mean that there must have existed two to three million programmers constantly writing, testing, debugging and documenting code. That would be about as many programmers as we have in China today, wouldn't it? Question 5: What about the competition? So far, I have come up with two things here: 1) IBM had their own programming language, PL/I. Above I have assumed that the majority of code has been written exclusively using Cobol. However, all other things being equal I wonder if IBM marketing had really pushed their own development off the market in favor of Cobol on their machines. Was there really no relevant code base of PL/I? 2) Sometimes (also on this board in the thread quoted above) I come across the claim that the "200 billion lines of code" are simply invisible to anybody outside of "governments, banks ..." (and whatnot). Actually, the DoD had funded their own language in order to increase cost effectiveness and reduce the proliferation of programming language. This lead to their use of Ada. Would they really worry about having so many different programming languages if they had predominantly used Cobol? If there was any language running on "government and military" systems outside the perception of mainstream computing, wouldn't that language be Ada? I hope someone can point out any flaws in my assumptions and/or conclusions and shed some light on whether the above claim has any truth to it or not.

  • Jquery fade and swap an element when clicked which will also relate to an accordian menu

    - by Nik
    You will notice when you click posture 1 the description drops down and images appear on the right. Now when you click posture 2 or posture 3 the images and description change as they should. What I need to do now is - If posture 1 has been clicked and then posture 2 is clicked the posture 1 menu needs to close so that there is only one posture description visible at one time. If I could also make it so that if the current open posture item is clicked so that it closes and there are no open posture descriptions that there also no images displayed on the right. Finally is there a way to make sure only one set of animation images is running, because just say the user goes through all 26 options and they continue to run in the background it may get sluggish (thanks to Nick Craver for bringing that up). At this stage only posture 1, 2 and 3 are available. Ok finally some code - //Description drop-down boxes $(document).ready(function(){ //Hide (Collapse) the toggle containers on load $(".toggle_container").hide(); //Switch the "Open" and "Close" state per click $("h5.trigger").toggle(function(){ $(this).addClass("active"); }, function () { $(this).removeClass("active"); }); //Slide up and down on click $("h5.trigger").click(function(){ $(this).next(".toggle_container").slideToggle("slow"); }); }); //Images on the right fade in and out thanks to aSeptik $(document).ready(function(){ $('#section_Q_01,#section_Q_02,#section_Q_03').hide(); $(function() { $('h5.trigger a').click( function(e) { e.preventDefault(); var trigger_id = $(this).parent().attr('id'); //get id Q_## $('.current').removeClass('current').hide(); //add a class for easy access & hide $('#section_' + trigger_id).addClass('current').fadeIn(5000); //show clicked one }); }); }); //Fading pics $(document).ready(function(){ $('.pics').cycle({ fx: 'fade', speed: 2500 }); }); Description boxes - <h5 class="trigger" id="Q_01" ><a href="#">Posture 1 : Standing Deep Breathing :</a></h5> <div class="toggle_container" > <div class="block"> <span class="sc">Pranayama Series</span> <p class="bold">Benefits:</p> </div> </div> <h5 class="trigger" id="Q_02" ><a href="#">Posture 2 : Half Moon Pose With Hands To Feet Pose :</a></h5> <div class="toggle_container"> <div class="block"> <span class="sc">Ardha Chandrasana with Pada-Hastasana</span> <p class="bold">Benefits:</p> </div> </div> <h5 class="trigger" id="Q_03" ><a href="#">Posture 3 : Awkward Pose :</a></h5> <div class="toggle_container"> <div class="block"> <span class="sc">Utkatasana</span> <p class="bold">Benefits:</p> </div> </div> and the images on the right - <div id="section_Q_01" class="01"> <div class="pics"> <img src="../images/multi/poses/pose1/Pranayama._01.jpg"/> <img src="../images/multi/poses/pose1/Pranayama._02.jpg"/> <img src="../images/multi/poses/pose1/Pranayama._03.jpg"/> </div> </div> <div id="section_Q_02" class="02"> <div class="pics"> <img src="../images/multi/poses/pose2/Half_Moon_Pose_04.jpg" /> <img src="../images/multi/poses/pose2/Backward_Bending_05.jpg" /> <img src="../images/multi/poses/pose2/Hands_to_Feet_Pose_06.jpg" /> </div> </div> <div id="section_Q_03" class="03"> <div class="pics"> <img src="../images/multi/poses/pose3/Awkward_01.jpg" /> <img src="../images/multi/poses/pose3/Awkward_02.jpg" /> <img src="../images/multi/poses/pose3/Awkward_03.jpg" /> </div> </div> It would be a bonus if images faded out when another element is clicked... but not a big deal. Thanks for having a look

  • best way to get new access_token using PHP sdk

    - by randy
    I am getting the error "An active access token must be used to query information about the current user". There seems to be tons of articles and ideas, but am very confused and it seems that things are changing as well. A lot say to use offline-access but that appears to be going away. I did find this article. Does anyone have an example using the PHP SDK? I tried doing something like the below but it does not seem to work; $FBuser is still zero: $token_url = "https://graph.facebook.com/oauth/access_token?" . "client_id=" . FB_APP_ID . "&client_secret=" . FB_APP_SECRET . "&grant_type=client_credentials"; list($name, $ACCESS_TOKEN) = explode("=", file_get_contents($token_url) ); $facebook->setAccessToken(ACCESS_TOKEN); $FBuser = $facebook->getUser();
