  • MVC alternatives: examples of MVA & AVC?

    - by Phillip Oldham
    I'm interested in learning about the alternative patterns to Model-View-Controller, specifically the Model-View-Adapter and Application-View-Controller patterns. Google results tend to be either a high-level overview or Java-based. Can anyone either provide, or point me to, an example of these patterns in either PHP, Python or JavaScript?

  • Correct term for PSD to HTML to CMS

    - by John Magnolia
    Hi, I have heard a lot of different terms to describe the process of turning a website design into a editable CMS. Currently I take the design and "slice" this up into HTML and CSS then I "plug" this into a CMS. I would class this as frontend development depending on the level of customisation required for the CMS. The reason I ask is I am currently writing up my CV and have become stuck on the correct term for this. Kind Regards

  • Sound Complete Not Firing (AS3)

    - by JasonMc92
    I have a bit of a quandary. I need to call a function inside a MovieClip once a particular sound has finished playing. The sound is played via a sound channel in an external class which I have imported. Playback is working perfectly. Here is the relevent code from my external class, Sonus. public var SFXPRChannel:SoundChannel = new SoundChannel; var SFXPRfishbeg:Sound = new sfxpr_fishbeg(); var SFXPRfishmid:Sound = new sfxpr_fishmid(); var SFXPRfishend3:Sound = new sfxpr_fishend3(); var SFXPRfishend4:Sound = new sfxpr_fishend4() public function PlayPrompt(promptname:String):void { var sound:String = "SFXPR" + promptname; SFXPRChannel = this[sound].play(); } This is called via an import in the document class "osr", thus I access it in my project via "osr.Sonus.---" In my project, I have the following line of code. osr.Sonus.SFXPRChannel.addEventListener(Event.SOUND_COMPLETE, promptIsFinished); function prompt():void { var level = osr.Gradua.Fetch("fish", "arr_con_level"); Wait(true); switch(level) { case 1: osr.Sonus.PlayPrompt("fishbeg"); break; case 2: osr.Sonus.PlayPrompt("fishmid"); break; case 3: osr.Sonus.PlayPrompt("fishend3"); break; case 4: osr.Sonus.PlayPrompt("fishend4"); break; } } function Wait(yesno):void { gui.Wait(yesno); } function promptIsFinished(evt:Event):void { Wait(false); } osr.Sonus.PlayPrompt(...) and gui.Wait(...) both work perfectly, as I use them in other contexts in this part of the project without error. Basically, after the sound finishes playing, I need Wait(false); to be called, but the event listener does not appear to be "hearing" the SOUND_COMPLETE event. Did I make a mistake somewhere? For the record, due to my project structure, I cannot call the appropriate Wait(...) function from within Sonus. Help?

  • Should I move this task to a message queue?

    - by Fedyashev Nikita
    I'm a big fan of using message queue systems(like Apache ActiveMQ) for the tasks which are rather slow and do not require instant feedback in User Interface. The question is: Should I use it for other tasks(which are pretty fast) and do not require instant feedback in User Interface? Or does it in involve another level of complexity without not so much benefits?

  • Warning produced by f#: value has been copied to ensure the original is not mutated

    - by user1878761
    The first definition below produces the warning in the title when compiled with f# 3.0 and the warning level set to 5. The second definition compiles cleanly. I wondered if someone could please explain just what the compiler worries I might accidentally mutate, or how would splitting the expression with a let clause help avoid that. Many thanks. let ticks_with_warning () : int64 = System.DateTime.Now.Ticks let ticks_clean () : int64 = let t = System.DateTime.Now t.Ticks

  • LInux C++: how do profile time wasted due to cache misses?

    - by anon
    I know that I can use gprof to benchmark my code. However, I have this problem -- I have a smart pointer that has an extra level of indirection (think of it as a proxy object). As a result, I have this extra layer that effects pretty much all functions, and screws with caching. Is there a way to measure the time my CPU wastes due to cache misses? Thanks!

  • a design to avoid circular reference in this scenario

    - by BDotA
    Here is our dependency tree: BigApp - Child Apps - Libraries ALL of our components are HEAVILY using one of the Libraries as above ( LibA). But it has a ‘few’ public methods that require classes from ‘higher-level’ assemblies and we want to avoid CIRCULAR references. What do you propose as a good design for this?

  • SQL Server 2008 error message from store procedure

    - by George2
    Hello everyone, When we met with such error message from store procedure, Message 1205, Level 13, State 52, the process Pr_FooV2, Line 9 Services (Process ID 111) and another process is deadlock in the lock | communication buffer resources, and has been chosen as the deadlock victim. Rerun the transaction. I am wondering whether such messages are stored in log files? I searched log folder of my SQL Server 2008 installation root (in my environment, it is C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\Log), but can not find such files. thanks in avdance, George

  • Restricting access to a subdirectory on linux

    - by David
    I'm looking for a way to make a directory accessible only to its parent directories. That is, suppose you have two directories, A and B, at the same level in the file hierarchy. Now suppose that you have a directory A' which is a subdirectory of A. I'd like to enforce that A is able to access the contents of A' but B is not.

  • When to use new layouts and when to use new activities?

    - by cmdfrg
    I'm making a game in Android and I'm trying to add a set of menu screens. Each screen takes up the whole display and has various transitions available to other screens. As a rough summary, the menu screens are: Start screen Difficult select screen Game screen. Pause screen. Game over screen. And there are several different ways you can transition between screen: 1 - 2 2 - 3 3 - 4 (pause game) 4 - 1 (exit game) 4 - 3 (resume game) 3 - 5 (game ends) Obviously, I need some stored state when moving between screens, such as the difficulty level select when starting a game and what the player's score is when the game over screen is shown. Can anyone give me some advice for the easiest way to implement the above screens and transitions in Android? All the create/destroy/pause/resume methods make me nervous about writing brittle code if I'm not careful. I'm not fond of using an Activity for each screen. It seems too heavy weight, having to pass data around using intents seems like a real pain and each screen isn't a useful module by itself. As the "back" button doesn't always go back to the previous screen either, my menu layout doesn't seem to fit the activity model well. At the moment, I'm representing each screen as an XML layout file and I have one activity. I set the different buttons on each layout to call setContentView to update the screen the main activity is showing (e.g. the pause button changes the layout to the pause screen). The activity holds onto all the state needed (e.g. the current difficulty level and the game high score), which makes it easy to share data between screens. This seems roughly similar to the LunarLander sample, except I'm using multiple screens. Does what I have at the moment sound OK or am I not doing things the typical Android way? Is there a class I can use (e.g. something like ViewFlipper) that could make my life easier? By the way, my game screen is implemented as a SurfaceView that stores the game state. I need the state in this view to persist between calls to setContentView (e.g. to resume from paused). Is the right idea to create the game view when the activity starts, keep a reference to it and then use this reference with setContentView whenever I want the game screen to appear?

    I'm would like to use Scala to persist data to a relational database, so what I am looking for are examples of CRUD operations using Scala. I would like to code on a lower level of abstraction than an ORM like Hibernate/Toplink (read:JDBC), but between us, I would like to see examples of all types. Thanks folks.

  • At What point should you understand References?

    - by Vaccano
    I asked a question like this in an interview for a entry level programmer: var instance1 = new myObject{Value = "hello"} var instance2 = instance1; instance1.Value = "bye"; Console.WriteLine(instance1.Value); Console.WriteLine(instance2.Value); The applicant responded with "hello", "bye" as the output. Some of my co-workers said that "pointers" are not that important anymore or that this question is not a real judge of ability. Are they right?

    I need to get all substrings from string. For ex: StringParser.GetSubstrings("[start]aaaaaa[end] wwwww [start]cccccc[end]", "[start]", "[end]"); that returns 2 string "aaaaaa" and "cccccc" Suppose we have only one level of nesting. Not sure about regexp, but I think it will be userful.

  • Lambda Expressions for a 5th Grader

    - by Randy Minder
    If you had to explain Lambda expressions to a 5th grader, how would you do it? And what examples might you give, or resources might you point them to? I may be finding myself in the position of having to teach this to 5th grade level developers and could use some assistance. Thanks very much.
