  • how to learn a library/framework structure?

    - by fayer
    a lot of people are contributing to open source libraries/frameworks. i wonder how these people learn the structure so that they can contribute? lets take doctrine and symfony as an example. is there a blueprint over these frameworks to give the developers an insight of the structure? or do they just download it and study the code? how does it work? please you contributors, share your learning strategies! thanks

  • Android googlemap Out of memory

    - by Xiaofeng
    Hi, I made an android application with googlemap api, and draw some 16x16 png (about 200 count) on overlay. When I move or zoom on/in mapview, "out of memory" error occurs very often. I also used the googlemap appication in my htc itself. Seams that it uses about 14+MB memmory, and never happens "out of memory". How to save memmory usage in a googlemap api, or how to enlarge android api memmory limit. Thanks a lot!

  • What is the best way to create a shortcut hook mechanism for Office

    - by rak3sh
    I am looking to create shortcut handler for MS Office. I am creating an addin with VS2010 for Office 2010. The handler needs to listen to all keyboard events when Word/PowerPoint is active. Although there is a lot of material for creating application level shortcut handlers, I couldn't find one that was specific to Office. It would be great if somebody could suggest techniques with sample c# code. Thanks

  • Unit tests and fixtures

    - by Wizzard
    We have a bunch of unit tests which test a lot of webpages and REST API services. Currently when our tests run it pulls from these pages live but this can take ages to run sometimes, and it also feels like the tests should be testing more of our code - not just relying on them being up and responding (if that makes sense..). Is it better practice to save a valid api response and with the unit tests load this in during setup? Thoughts?

  • Is it a good idea for me to learn Python before C or some other Compiler language?

    - by Dream Lane
    Right now I am going through MIT's introduction to Computer Science course via OpenCourseWare. As a part of this course I am learning the Python Language. I've read a lot of things about the benefits of learning C. Before I dig any deeper into Python I wonder if I will be hindered or helped by learning Python first. Do you think that I will develop any bad habits or anything like that from Python?

  • C#: Perform Operations on GPU, not CPU (Calculate Pi)

    - by Alex
    Hello, I've recently read a lot about software (mostly scientific/math and encryption related) that moves part of their calculation onto the GPU which causes a 100-1000 (!) fold increase in speed for supported operations. Is there a library, API or other way to run something on the GPU via C#? I'm thinking of simple Pi calculation. I have a GeForce 8800 GTX if that's relevant at all (would prefer card independent solution though). Any hints are appreciated!

  • What can you do and not do with java annotations?

    - by swampsjohn
    The typical use-case is for simple things like @Override, but clearly you can do a lot more with them. If you push the limits of them, you get things like Project Lombok, though my understanding is that that's a huge abuse of annotations. What exactly can you do? What sort of things can you do at compile-time and run-time with annotations? What can you not do?

  • Create automatically only getters in Eclipse

    - by lerad
    In Eclipse is it possible to create automatically Getters and Setters for a field. But I have a lot of private fields for which only getters should exist. Is somewhere in Eclipse a "create Getters" Function which does not create setters too? Well, it is not so much work to write getters, but doing it automatically would be nice :) Thank you, lerad

  • What about buffering FileInputStream?

    - by Pregzt
    I have a piece of code that reads hell of a lot (hundreds of thousand) of relatively small files (couple of KB) from the local file system in a loop. For each file there is a java.io.FileInputStream created to read the content. The process its very slow and take ages. Do you think that wrapping the FIS into java.io.BufferedInputStream would make a significant difference?

  • Where are strings more useful than a StringBuilder?

    - by DJay
    Lot of questions has been already asked about the differences between string and string builder and most of the people suggest that string builder is faster than string. I am curious to know if string builder is too good so why string is there? Moreover, can some body give me an example where string will be more usefull than string builder?

  • jquery in ajax loaded content

    - by Kim Gysen
    My application is supposed to be a single page application and I have the following code that works fine: home.php: <div id="container"> </div> accordion.php: //Click functions: load content $('#parents').click(function(){ //Load parent in container $('#container').load('http://www.blabla.com/entities/parents/parents.php'); }); parents.php: <div class="entity_wrapper"> Some divs and selectors </div> <script type="text/javascript"> $(document).ready(function(){ //Some jQuery / javascript }); </script> So the content loads fine, while the scripts dynamically loaded execute fine as well. I apply this system repetitively and it continues to work smoothly. I've seen that there are a lot of frameworks available on SPA's (such as backbone.js) but I don't understand why I need them if this works fine. From the backbone.js website: When working on a web application that involves a lot of JavaScript, one of the first things you learn is to stop tying your data to the DOM. It's all too easy to create JavaScript applications that end up as tangled piles of jQuery selectors and callbacks, all trying frantically to keep data in sync between the HTML UI, your JavaScript logic, and the database on your server. For rich client-side applications, a more structured approach is often helpful. Well, I totally don't have the feeling that I'm going through the stuff they mention. Adding the javascript per page works really well for me. They are html containers with clear scope and the javascript is just related to that part. More over, the front end doesn't do that much, most of the logic is managed based on Ajax calls to external PHP scripts. Sometimes the js can be a bit more extended for some functionalities, but all just loads as smooth in less than a second. If you think that this is bad coding, please tell me why I cannot do this and more importantly, what is the alternative I should apply. At the moment, I really don't see a reason on why I would change this approach as it just works too well. I'm kinda stuck on this question because it just worries me sick as it seems to easy to be true. Why would people go through hard times if it would be as easy as this...

  • Techniques for querying a set of object in-memory in a Java application

    - by Edd Grant
    Hi All, We have a system which performs a 'coarse search' by invoking an interface on another system which returns a set of Java objects. Once we have received the search results I need to be able to further filter the resulting Java objects based on certain criteria describing the state of the attributes (e.g. from the initial objects return all objects where x.y z && a.b == c). The criteria used to filter the set of objects each time is partially user configurable, by this I mean that users will be able to select the values and ranges to match on but the attributes they can pick from will be a fixed set. The data sets are likely to contain <= 10,000 objects for each search. The search will be executed manually by the application user base probably no more than 2000 times a day (approx). It's probably worth mentioning that all the objects in the result set are known domain object classes which have Hibernate and JPA annotations describing their structure and relationship. Off the top of my head I can think of 3 ways of doing this: For each search persist the initial result set objects in our database, then use Hibernate to re-query them using the finer grained criteria. Use an in-memory Database (such as hsqldb?) to query and refine the initial result set. Write some custom code which iterates the initial result set and pulls out the desired records. Option 1 seems to involve a lot of toing and froing across a network to a physical Database (Oracle 10g) which might result in a lot of network and disk activity. It would also require the results from each search to be isolated from other result sets to ensure that different searches don't interfere with each other. Option 2 seems like a good idea in principle as it would allow me to do the finer query in memory and would not require the persistence of result data which would only be discarded after the search was complete. Gut feeling is that this could be pretty performant too but might result in larger memory overheads (which is fine as we can be pretty flexible on the amount of memory our JVM gets). Option 3 could be very performant but is something I would like to avoid as any code we write would require such careful testing that the time taken to acheive something flexible and robust enough would probably be prohibitive. I don't have time to prototype all 3 ideas so I am looking for comments people may have on the 3 options above, plus any further ideas I have not considered, to help me decide which idea might be most suitable. I'm currently leaning toward option 2 (in memory database) so would be keen to hear from people with experience of querying POJOs in memory too. Hopefully I have described the situation in enough detail but don't hesitate to ask if any further information is required to better understand the scenario. Cheers, Edd

  • What does the exception "javax.servlet.jsp.JspException: Broken pipe" signify?

    - by Ruepen
    I'm getting the following error: javax.servlet.jsp.JspException: Broken pipe Now I have seen questions/answers with respects to the socket exception, but this error is coming from a different package. Any help is greatly appreciated. BTW, I am seeing quite a lot of these errors in a struts web app Weblogic Node logs and I am thinking that it has to do with end users closing their web browser before the page reloads/executes the next step (database transaction which takes quite a bit of time to execute, anywhere from 30 seconds to 4 mins).

    I see this a lot now, jpg files displaying your IP address. To you of course, not to others, they would see their own For example: How is this even possible? If this is possible, would it be possible to log an IP into a MySQL database from the picture as well? Is my IP getting logged when I view this?

  • Lift session valid ajax callback from a static javascript

    - by ChrisJamesC
    I am currently implementing a graph visualisation tool using lift on the server side and d3 ( a javascript visualisation framework) for all the visualisation. The problem I have is that in the script I want to get session dependent data from the server. So basically, my objective is to write lift-valid ajax callbacks in a static js script. Here is what I tried so far: What I have tried so far If you feel that the best solution is one that I already tried feel free to post a detailed answer telling me how to use it exactly and how it completely solves my problem. REST interface Usually what one would do to get data from a javascript function in lift is to create a REST interface. However this interface will not be linked to any session. This is the solution I got from my previous question: Get json data in d3 from lift snippet Give function as argument of script Another solution would be to give the ajaxcallback as an argument of the main script called to generate my graph. However I expect to have a lot of callbacks and I don't want to have to mess with the arguments of my script. Write the ajax callback in another script using lift and call it from the main script This solution, which is similar to a hidden text input is probably the more likely to work. However it is not elegant and it would mean that I would have to load a lot of scripts on load, which is not really conveniant. Write the whole script in lift and then serve it to the client This solution can be elegant, however my script is very long and I would really prefer that it remainss static. What I want On client side While reviewing the source code of my webpage I found that the callback for an ajaxSelect is: <select onchange="liftAjax.lift_ajaxHandler('F966066257023LYKF4=' + encodeURIComponent(this.value), null, null, null)" name="F96606625703QXTSWU" id="node_delete" class="input"> Moreover, there is a variable containing the state of the page in the end of the webpage: var lift_page = "F96606625700QRXLDO"; So, I am wondering if it is possible to simulate that my ajaxcall is valid using this liftAjax.lift_ajaxHandler function. However I don't know the exact synthax to use. On server side Since I "forged" a request on client side, I would now like to get the request on client side and to dispatch it to the correct function. This is where the LiftRules.dispatch object seems the best solution: when it is called, all the session management has been made (the request is authentified and linked to a session), however I don't know how to write the correct piece of code in the append function. Remark In lift all names of variables are changed to a random string in order to increase the security, I would like to have the same behavior in my application even if that will probably mean that I will have to "give" the javascript these values. However an array of 15 string values is still a better tradeoff than 15 functions as argument of a javascript function.

  • R segfault when running via Rpy on linux

    - by Zhang18
    I'm running R via Rpy on a redhat linux distribution. Periodically I'll encounter this error message: *** caught segfault *** address (nil), cause 'unknown' And the entire program dies right there. It usually occurs when I run a lot of regression r.lm(). But by simply running the identical code again, the problem may or may not go away (so not always reproduceable). Does anyone know what might be causing this, and/or how I can prevent it from happening?
