  • PHP Framework Benefits / Downfalls

    - by Lizard
    I have been a PHP developer for about 10 years now and until about a month ago I have never used a framework. The framework I am now using due to an existing codebase is cakePHP 1.2 I can see certain benefits of the frameworks with the basic helpers like default layouts. I can deffinately seen the benefits of MVC keeping the logic sperate etc. But the query building just seems to be bloated. Is this expected? Am I likely to be able to build better queries than the framework could build? I just feel I could get my apps running better without a framework. What are your thoughts?

  • Android ROM Development. What does it take?

    - by Priyank
    Hi. I have been developing android apps out of hobby and fun. I want to get more serious about android development. One particular thing that I am very keen on doing (or atleast trying my hand at) is andoroid ROM development for specific handsets. Like, maybe outdated HTC Touch. (Elf/Elfin). I am at a loss to understand, what does it take to get started in right direction and what does it entails? I would really appreciate your help if you could point me to some resources which would highlight ROM Development for Android specifically. (Fundamentals of ROM development irrespective of OS would help too). Cheers

  • Does iOS 4 Have "Real" Multitasking?

    - by pkulak
    Ever since the first beta came out I've been trying to find out if "real" multitasking is possible. I.E., can you put a program in the background and have it hang on to a network connection indefinitely? I'm thinking about IM or IRC apps, for example. I've compiled an app myself on OS 4, and without changing a thing it appeared to stay running in the background, but for all I know it was just suspended to memory. The docs say the best you can do is request up to 10 minutes, but in the developer presentation they showed off Skype sitting in the background and then notifying the user that a call was coming in. Does anyone know for sure how this is all going to work?

Also i have implemented the sensors library as instructed in the Android-Reference along the sensors.h template. I am still unable to get any response at the apps level. How do i trace this issue? what might be the problem? Thanks in advance UPDATE: Jorgesys's link below points to a great APP to test if the sensor drivers are functioning properly or not. Not that i know they are not functioning, Any ideas of on where to dig??...

  • MPMoviePlayerController seems to make 2 calls for each movie

    - by user76328
    I seem to have an issue where an iphone app using the MPMoviePlayerController seems to make 2 calls to the server for each video it wants to play back. This occurs with iphone 3.x OS and libraries but not with iphone 2.x. I know that iphone does progressive download and will make multiple 206 requests, etc. but as far as our back end is concerned the player appears to make 2 separate sessions. This only appears to be an issue with iPhone native apps and not iphone videos played through safari. Additional info from apple: iPhone OS 3.0 added support for streaming audio and video over HTTP, and MPMoviePlayerController must validate the media before playback to determine if it is streaming content or progressively downloaded content. This is the delay you are experiencing. On a fast network, the delay should be minimized. Is this double check causing 2 sessions be created for each video request? Any one else seeing same issue? Is there a remedy?

  • How to reference an object in a lower fragment in android

    - by Silas Greenback
    I am trying to build a help screen that is going to go on a mediaplayer. The idea is to put a fragment with a transparent theme on top of the current view. (See How do I create a help overlay like you see in a few Android apps and ICS? for the basic idea). Now, I understand the steps in the mentioned link, but how do I connect the circles and arrows and paragraphs next to each one (explaining what each one was) to the lower object? Example, I have an object: R.id.music_button and I want there to be and arrow that points to music button. Trying to support as many devices as we do it will be very difficult to just draw a few pictures as part of the top layout and expect them to line up. Again, how do I reference an object on a fragment below the top level? Thanks

  • what do i need to do now that I want to take programming hobby to next level ?

    - by hohog
    i've always wanted to make games but did not start actively learning programming by myself until 1st year of university. i kept going throughout university learning new languages, showing off things i had made, while neglecting my major in Biology. Anyways, i've ended up with an Economics degree, with a portfolio of SaaS and web apps i had created so i could eat during my final year. So far, I'm getting a few interviews here and there in web programming positions. When I get a logic pretest, I fail miserably. or job requires comp sci degree. I mean I can easily design and code an entire app which I emphasize through my portfolio.... but i dont know why I am so slow at logic puzzles on prescreening interview... So what should I do now ? get certificates in languages ? go back to school and learn CS ? is it too late to get into windows programming jobs than web programming ?

  • Qt applications on new Mac App Store

    - by PDI
    I have a Qt app that runs on OS X that has potential to go on the new Mac App Store. I have reviewed the guidelines at https://developer.apple.com/appstore/mac/resources/approval/guidelines.html. I also saw a post here on SO about Java and the AppStore. Has anyone else considered this with their own apps and whether or not the Qt framework will run afoul of the App police? You still have to stay within the Apple HIG, i.e. no theming and cannot use private APIs. Still seems like a risky proposition over pure ObjC. Anyone else tempted?

  • Eager loading in EF1.0

    - by Dave Swersky
    I have a many-to-many relationship: Application - Applications_Servers - Server This is set up in my Entity Data Model and all is well. My problem is that I'd like to eager-load the whole graph of Applications so that I have an IEnumerable<Applications>, each Application member populated with the Servers collection associated by the many-to-many relationship. Normally this wouldn't be a problem, but according to my research there must be a navigation property between Application and Server. This is not the case for me because my Applications_Servers join table has more in it than just the two keys. Therefore, there is no navigation property directly between Application and Server, and this doesn't work: var apps = (from a in context.Application.Include("Server") select a).ToList(); I get an error saying there is no navigation property on Application called "Server", and that's correct, there is none. How do I write the query to eager-load my Applications with their Servers in this case?

  • initWithCoder breaking my touch events (touchBegan, touchMoved, etc)

    - by Adam
    So I have a UIView that has been setup, and in each touch event handler I have an NSLog fire off a message to the console. - (void) touchesBegan:(NSSSet*)touches withEvent:(UIEvent*)event { NSLog(@"touchesBegan"); } And that pretty much works as expected. But once I implement initWithCoder (even blank) - (id)initWithCoder:(NSCoder*)coder { return self; } I no longer receive the message to my console (or can hit breakpoints obviously). This is my first app so I'm probably missing something dumb, but I've looked through various example apps and I don't appear to be missing any code that would re-enable touch events.

  • Where is the chink in Google Chrome's armor?

    - by kudlur
    While browsing with Chrome, I noticed that it responds extremely fast (in comparison with IE and Firefox on my laptop) in terms of rendering pages, including JavaScript heavy sites like gmail. This is what googlebook on Chrome has to say tabs are hosted in process rather than thread. compile javascript using V8 engine as opposed to interpreting. Introduce new virtual machine to support javascript heavy apps introduce "hidden class transitions" and apply dynamic optimization to speed up things. Replace inefficient "Conservative garbage colllection" scheme with more precise garbage collection scheme. Introduce their own task scheduler and memory manager to manage the browser environment. All this sounds so familiar, and Microsoft has been doing such things for long time.. Windows os, C++, C# etc compilers, CLR, and so on. So why isn't Microsoft or any other browser vendor taking Chrome's approach? Is there a flaw in Chrome's approach? If not, is the rest of browser vendor community caught unaware with Google's approach?

  • Java Swing architecture for flipping through JPane based views

    - by imhotep
    Hi all, I have done a couple of simple swing based apps with static layout, but now I've run into a problem while trying to create an app containing multiple views which are changed by pressing appropriate navigational button. You could compare the idea to a website so that every view has buttons to access certain other views but this would work inside a single JFrame. I've found that maybe CardLayout (Cardlayout example) might be appropriate solution for this kind of structure, but I'm unable to figure out a way to switch the views from the buttons which are inside of the JPanes that I've implemented in their separate classes, Of course one way would be to instantiate everything in the parent class like in the small java tutorial example, but this isn't quite clean nor modular for multiple views, isn't it. How can this be implemented so that I can access the view switching method?

  • Bug Tracker - Feature set - Comparison

    - by Blankman
    Hi, I have installed and played around with a few bug tracking apps, and just wanted to get some feedback and features that a typical (or not so typical) bug tracking software has. I want to make sure I am not overlooking a feature that might come in handy. So the biggest idea is around a bug, which is associated with: Bugs - product - product version - component (specific component of the product) - status - priority - assigned to - expected time to finish - time spent on it so far - created by - historical log of bug Forums Wiki I guess the above functionality is common to all, so what exactly differentiates them? Is it simply the UI and filtering/searching that you base a decision on? (I am comparing something like Jira with FogBugz)

  • Convert a GTK python script to C

    - by Jessica
    The following script will take a screenshot on a Gnome desktop. import gtk.gdk w = gtk.gdk.get_default_root_window() sz = w.get_size() pb = gtk.gdk.Pixbuf(gtk.gdk.COLORSPACE_RGB,False, 8, sz[0], sz[1]) pb = pb.get_from_drawable(w, w.get_colormap(), 0, 0, 0, 0, sz[0], sz[1]) if (pb != None): pb.save("screenshot.png", "png") print "Screenshot saved to screenshot.png." else: print "Unable to get the screenshot." Now, I've been trying to convert this to C and use it in one of the apps I am writing but so far i've been unsuccessful. Is there any what to do this in C (on Linux)? Thanks! Jess.

  • Can I attach a .NET TraceListener to an externally running process?

    - by BBlake
    I am developing an application scheduling program that will run other applications using System.Diagnostics.Process. The external applications are of various types (some .NET and some not). For those external apps that have trace logging enabled, is there a way that I can attach the tracelistener of the parent/calling application to listen to and record all the trace output from the child/called application to the parent application's trace output? This is not primarily for debugging purposes. This is more to track trace output from all the various scheduled applications by collecting it into one place as much as possible. The scheduler app is still in the early design stages, but will be .NET, and I'm trying to clear up potential design issues before I get into it too far.

  • Windows azure deployment

    - by smoothe
    I just built a simple hello world windows azure service containing just one web role, I used visual studio 2008 and Windows azure tools for VS 1.2 I am pretty new to this and I have been trying to deploy an application all afternoon now. I'm in australia and deploying in the region Asia anywhere. I have pretty much followed the info provided on MSDN and it says uploaded 95% then after about ten minutes the deployment disappears. I have tried using the old windows azure developer portal and 30minutes later I can not access the service and it's status is either busy or stopped. I have the introductory offer for an extra small compute instance on the subscription I am deploying to. Can anyone with experience with windows azure elaborate on the subject of deploying apps and the status on my application, I am very keen to get into the platform and this issue has just about spoiled my weekend.

  • How do you optimize database performance when providing results for autocomplete/iterative search?

    - by Howiecamp
    Note: In this question I'm using the term "autocomplete" (or "iterative search") to refer to returning search-as-you-type results, e.g. like Google Search gives you. Also my question is not specific to web applications vs. fat client apps. How are SQL SELECT queries normally constructed to provide decent performance for this type of query, especially over arbitrarily large data sets? In the case where the search will only query based on the first n characters (easiest case) am I still issuing a new SELECT result FROM sometable WHERE entry LIKE... on each keypress. Even with various forms of caching this seems like it might result in poor performance. In cases where you want your search string to return results with prefix matches, substring matches, etc. it's an even more difficult problem. Looking at a case of searching a list of contacts, you might return results that match FirstName + LastName, LastName + FirstName, or any other substring.

  • How To Collapse Just One Field in Django Admin?

    - by Apreche
    The django admin allows you to specify fieldsets. You properly structure a tuple that groups different fields together. You can also specify classes for certain groups of fields. One of those classes is collapse, which will hide the field under a collapsable area. This is good for hiding rarely used or advanced fields to keep the UI clean. However, I have a situation where I want to hide just one lonesome field on many different apps. This will be a lot of typing to create a full fieldset specification in every admin.py file just to put one field into the collapsed area. It also creates a difficult maintenance situation because I will have to edit the fieldset every time I edit the associated model. I can easily exclude the field entirely using the exclude option. I want something similar for collapse. Is this possible?

  • Should I use interface builder or not?

    - by Michael Waterfall
    I'd like to know more about the pros and cons of using interface builder when developing iPhone/iPad apps. I've written a fairly complex and customized app that's on the app store right now, but all of the interfaces are hand coded as they are fairly complex. I've customised the navigation and tab bars with backgrounds, table view cells are manually drawn for speed, and some views are complex and scalable with many subviews. I'm pondering whether or not to start using interface builder but I'm not sure to what extent I'll use it and whether it's worth it at all. Is it quicker? Can things still be easily customised? Any advice would be most welcome!

  • Where are graphically pleasing examples of Lists

    - by slim
    Anyone know of good code examples of how to make lists look different than your everyday average black list or more graphically pleasing than you usually see in android apps. I've looked through google code but haven't found too many. I'm looking for different and eye catching lists. I hope this question isn't too generic. Also i'm open to anything, code, examples, blog posts, etc, you name it. I've really struggled with lists and making them look more snazzy. I'm talking more the code level not the graphics or icons used.

  • Pattern for iPhone background loading during init?

    - by Rob S.
    Hi everyone, I'm currently kicking off a background thread to do some REST queries in my app delegate's didFinishLaunchingWithOptions. This thread creates some objects and populates the model as the rest of the app continues to load (because I don't block, and didFinishLaunchingWithOptions returns YES). I also put up a loading UIViewController 'on top' of the main view that I tear down after the background initialization is complete. My problem is that I need to notify the first view (call it the Home view) that the model is ready, and that it should populate itself. The trick is that the background download could have finished before Home.viewDidAppear is called, or any of the other Home.initX methods. I'm having difficulty synchronizing all of this and I've thought about it long enough that it feels like I'm barking up the wrong tree. Are there any patterns here for this sort of thing? I'm sure other apps start by performing lengthy operations with loading screens :) Thanks!

  • How to step frames in a movie recorded by iPhone

    - by aron
    Is there a way to have my iPhone program step frame by frame through a movie recorded by the iPhone? What I want to do is have the user record a quicktime movie, then be able to step through the movie frame by frame. Alternately, I suppose if there was a way to extract every single frame from the movie to a jpg, then I could easily step through the pictures. Anyone know of a way to do this??? I suppose the third option (which might not get past Apple's store) is to capture the movie the way the old jailbroken apps did, which is somehow capture the pictures directly from the camera view???? Any help appreciated. Thanks in advance!!!!

  • Tool to measure Render time

    - by Noob
    Hi Folks, Is there a tool out there to measure the actual Render time of an element(s) on a page? I don't mean download time of the resources, but the actual time the browser took to render something. I know that this time would vary based on factors on the client machine, but would still be very handy in knowing what the rendering engine takes a while to load. I would imagine this should be a useful utility since web apps are becoming pretty client heavy now. Any thoughts?
