  • Why does OS X insist on spinning up all external drives when loading a file from the local drive?

    - by Phillip Oldham
    Why does OS X insist on spinning up all the attached external drives (firewire, usb) when loading a file from the local (internal) drive? It's driving me insane that I have to wait for 3 attached drives (1 back-up, 2 media) to spin up -- a total of 20s -- to access a file that is located only on my local/internal drive. There is no obvious need to access the other drives; nothing is being read from them and nothing need be written. Examples: Quicktime X opening a file from the local HDD. Starting Caffeine, an app which doesn't access any other files at all. Can I tell OS X to only spin those drives up when actually accessing them?

  • Project Server 2007 Task Updates hangs on 'Loading Grid...'

    - by entens
    A strange problem began occurring after applying MOSS2 (KB953334) and the August 2009 cumulative update to our Project server. When a user enters the 'Task Update' screen they are prompted to download a new ActiveX control. Upon refresh, and subsequent access attempts, the user is presented with a blank grid with the caption 'Loading Grid...' We have attempted to fix this issue by updating the 'Trusted Sites' list and changing the security settings according to KB818046. However, nothing seems to definitely fix the problem. Also, when the problem randomly fixes itself, it still occurs when viewing specific projects. Any ideas on a fix?

  • How can I automatically change the priority of Javaw.exe when loading Minecraft?

    - by Arch Angel
    I launch Minecraft.exe which invokes Javaw.exe. I wish for Javaw.exe to be running in High priority because Minecraft lags if not. I tried invoking Minecraft.exe with a high priority by doing this: Start "Minecraft" /high "C:\Users\Barrie\Documents\Program Files\Minecraft\Minecraft.exe" This would work if it wasn't for Minecraft loading Javaw.exe. I would love a simple solution - perhaps a command I can put into the batch script - which will change the priority of Javaw.exe after it loads. Edit: I'd like to thank everyone for their response to my issue. I fixed this by executing Minecraft.exe with a batch script then calling an AHK script to change the priority of Javaw.exe.

  • how can i unmarshall in jaxb and enjoy the schema validation without using an explicit schema file

    - by ekeren
    I am using jaxb for my application configurations I feel like I am doing something really crooked and I am looking for a way to not need an actual file or this transaction. As you can see in code I: 1.create a schema into a file from my JaxbContext (from my class annotation actually) 2.set this schema file in order to allow true validation when I unmarshal JAXBContext context = JAXBContext.newInstance(clazz); Schema mySchema = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI).newSchema(schemaFile); jaxbContext.generateSchema(new MySchemaOutputResolver()); // ultimately creates schemaFile Unmarshaller u = m_context.createUnmarshaller(); u.setSchema(mySchema); u.unmarshal(...); do any of you know how I can validate jaxb without needing to create a schema file that sits in my computer? Do I need to create a schema for validation, it looks redundant when I get it by JaxbContect.generateSchema ? How do you do this?

  • Why does this explicit call of a Scala method allow it to be implicitly resolved?

    - by Matt R
    Why does this code fail to compile, but compiles successfully when I uncomment the indicated line? (I'm using Scala 2.8 nightly). It seems that explicitly calling string2Wrapper allows it to be used implicitly from that point on. class A { import Implicits.string2Wrapper def foo() { //string2Wrapper("A") ==> "B" // <-- uncomment } def bar() { "A" ==> "B" "B" ==> "C" "C" ==> "D" } object Implicits { implicit def string2Wrapper(s: String) = new Wrapper(s) class Wrapper(s: String) { def ==>(s2: String) {} } } }

  • Should you correct compiler warnings about type conversions using explicit typecasts?

    - by BastiBechtold
    In my current project, the compiler shows hundreds of warnings about type conversions. There is a lot of code like this iVar = fVar1*fVar2/fVar3; // or even iVar = fVar1*fVar2/fVar3+.5f; which intentionally assign float values to int. Of course, I could fix these warnings using iVar = int(...); but that looks kind of ugly. Would you rather live with the ugliness or live with the warnings? Or is there even a clean solution?

  • Explicit method tables in C# instead of OO - good? bad?

    - by FunctorSalad
    Hi! I hope the title doesn't sound too subjective; I absolutely do not mean to start a debate on OO in general. I'd merely like to discuss the basic pros and cons for different ways of solving the following sort of problem. Let's take this minimal example: you want to express an abstract datatype T with functions that may take T as input, output, or both: f1 : Takes a T, returns an int f2 : Takes a string, returns a T f3 : Takes a T and a double, returns another T I'd like to avoid downcasting and any other dynamic typing. I'd also like to avoid mutation whenever possible. 1: Abstract-class-based attempt abstract class T { abstract int f1(); // We can't have abstract constructors, so the best we can do, as I see it, is: abstract void f2(string s); // The convention would be that you'd replace calls to the original f2 by invocation of the nullary constructor of the implementing type, followed by invocation of f2. f2 would need to have side-effects to be of any use. // f3 is a problem too: abstract T f3(double d); // This doesn't express that the return value is of the *same* type as the object whose method is invoked; it just expresses that the return value is *some* T. } 2: Parametric polymorphism and an auxilliary class (all implementing classes of TImpl will be singleton classes): abstract class TImpl<T> { abstract int f1(T t); abstract T f2(string s); abstract T f3(T t, double d); } We no longer express that some concrete type actually implements our original spec -- an implementation is simply a type Foo for which we happen to have an instance of TImpl. This doesn't seem to be a problem: If you want a function that works on arbitrary implementations, you just do something like: // Say we want to return a Bar given an arbitrary implementation of our abstract type Bar bar<T>(TImpl<T> ti, T t); At this point, one might as well skip inheritance and singletons altogether and use a 3 First-class function table class /* or struct, even */ TDictT<T> { readonly Func<T,int> f1; readonly Func<string,T> f2; readonly Func<T,double,T> f3; TDict( ... ) { this.f1 = f1; this.f2 = f2; this.f3 = f3; } } Bar bar<T>(TDict<T> td; T t); Though I don't see much practical difference between #2 and #3. Example Implementation class MyT { /* raw data structure goes here; this class needn't have any methods */ } // It doesn't matter where we put the following; could be a static method of MyT, or some static class collecting dictionaries static readonly TDict<MyT> MyTDict = new TDict<MyT>( (t) => /* body of f1 goes here */ , // f2 (s) => /* body of f2 goes here */, // f3 (t,d) => /* body of f3 goes here */ ); Thoughts? #3 is unidiomatic, but it seems rather safe and clean. One question is whether there are any performance concerns with it. I don't usually need dynamic dispatch, and I'd prefer if these function bodies get statically inlined in places where the concrete implementing type is known statically. Is #2 better in that regard?

  • Possible iphone animation timing/rendering bug?

    - by David
    Hi all, I have been working on an iphone apps for several weeks. Now I encounter an animation problem that I can't figure out how to resolve. Mayhbe you can help. Here is the details (a little long, bear with me): Basically the effect I want to achieve is, when user click a button, a loading view pops up, hiding the whole screen; and then the apps does a lot of heavy computation, which takes a few seconds. Once the computation is done, soem result views (something likes checkers on a checker board) are rendered under the loading view. Once all result views are rendered, I used animation animation to remove the loading view nand show the result views to the user. Here is what I do: when user click a button, run this code: [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:1.0]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(loadingViewInserted:finished:context:)]; // use a really high index number so it will always on top [self.view insertSubview:loadingViewController.view atIndex:1000]; [UIView commitAnimations]; In the "loadingViewInserted" function, it calls another function doing the heavy computation work. Once the computation is done, a lot of result views (like checkers on a checker board) are rendered under the loading view. for(int colIndex = 1; colIndex <= result.columns; colIndex++) { for(int rowIndex = 1; rowIndex <= result.rows; rowIndex++) { ResultView *rv = [ResultView resultViewWithData:results[colIndex][rowIndex]]; [self.view addSubview:rv]; } } Once all result views are added, following animation is invoked to remove the loading view: [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:1.0]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES]; [loadingViewController.view removeFromSuperview]; [UIView commitAnimations]; By doing this, most of the time (maybe 90%) it does exactly what I want. However, sometime I see some weird result: the loading view shows up first as expected, then before it disappears, some result views, which suppose to be under the loading view, suddenly appears on top of the loading view; and some of them are partial rendered. And then the loading view curled up, and everything looks normal again. The weird situation only lasts for less than a second, but already bad enough to screw up the UI. I have tried all different kinds of thing to fix this (using another thread to remove the loading view, make the loading view non-transparent), but none of them works. The only thing that makes a little better is, I hide all the result views first; after the last animation finished, in its call back, unhide all result views. But this loses the nice effect that when curling up the loading view, the results are already there. At this point, I really think this is a bug in iphone (I compile it with OS 3.0) OS. Or maybe you can point out what I have done wrong (or could do differently). (thanks for finishing this long post, :-) )

  • Can I grant explicit Javascript methods to a different-host iframe?

    - by Matchu
    I'm thinking about a system in which I allow users to create Javascript-empowered widgets for other users to embed in their dashboard on my website. I'd like to limit these widgets fairly strictly, so each would exist as an iframe kept on its own unique hostname: the widget with ID #47 would be accessible at w47.widgets.example.com, for example. It would be helpful, for permission-granting dialogs and the like, to allow the widget to call very specific methods explicitly granted by the parent window, without authorizing the iframe to do whatever it likes with the parent frame on the user's behalf. Is it possible for a parent document to explicitly allow certain method calls to a child document on a different host?

  • What if I made an explicit reference to 'this' for use inside an inner class?

    - by badp
    So far, I've used this approach to access this from the scope of an inner class: class FooManagementWindow extends JFrame { JButton rejectFoo; //... void getFooAcceptingPanel(){ //... final FooManagementWindow referenceToThis = this; rejectFoo = new JButton("Reject"); rejectFoo.addEventListener(new EventListener() { @Override public void actionPerformed(ActionEvent arg) { referenceToThis.setEnabled(false); //this requires a network call //... referenceToThis.setEnabled(true); //the user may resume his work } }); //... } } However, I just learned that instead of declaring referenceToThis, a direct reference is kept for me as: FooManagementWindow.this I have no reason to think my less standard approach may lead to errors or weird corner cases. Or are there?

  • Android SDK having trouble with ADB

  • can anyone help me through the preparation of Eclipse IDE for android developer in ubuntu 12.04?

    - by csbl
    I'm new to to Linux, in this particular case, to Ubuntu. I have a small android project I have to finnish until this Friday and I'm still stuck with the install and preparing of the development envrironment. The only thing I did was install the Eclipse IDE. I'm still missing the SDK, JAVA and anything else that might be needed. Can someone help me through this? It's only because I'm running out of time to develop, or else I would embarc on a deeper investigation of this OS. I tried the step to install android platforms, through Eclispe-Help-Install New Software, and I got the follwoing error messages, at the end of the process: [2012-06-06 17:35:56 - adb] /home/catia/android-sdks/platform-tools/adb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory [2012-06-06 17:35:56 - adb] 'adb version' failed! /home/catia/android-sdks/platform-tools/adb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory [2012-06-06 17:35:56 - adb] Failed to parse the output of 'adb version': Standard Output was: Error Output was: /home/catia/android-sdks/platform-tools/adb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory [2012-06-06 17:35:56 - adb] /home/catia/android-sdks/platform-tools/adb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory [2012-06-06 17:35:56 - adb] 'adb version' failed! /home/catia/android-sdks/platform-tools/adb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory [2012-06-06 17:35:56 - adb] Failed to parse the output of 'adb version': Standard Output was: Error Output was: /home/catia/android-sdks/platform-tools/adb: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory Can anyone help, please??

  • Is there a program to show programs loading during the boot process in real time?

    - by Gary M. Mugford
    Hi all, There are any number of programs that will show me WHAT will run during the boot process for Windows XP. I've always been partial to Mike Lin's version but there are several others, some of which are quite possibly superior. That's not the issue. What I'd really like is a program that would load first and then would list the programs that were about to load and then check them off as the programs loaded. This isn't something I necessarily need for myself. But certain family members get click happy as soon as they see the icon they eventually want to run and end up clicking on it. THIRTY TWO TIMES in one memorable crash-inducing spasm. If there was some way for 'progress' to be shown during the loading of from the various spots Windows auto-loads from, PLUS a BIG BANNER saying "Please do not move the mouse or click on anything until done.", I think I might cut down on my early morning family support calls significantly. I've tried a variety of searches, but I couldn't find the ones that show in real time in the forest of links to programs that will show the list after the fact. Any leads? If not, do any of you who write the after-the-fact listers want to take a shot at producing a utility to do what I think would be a relatively popular utility? Best of the season to all of you and yours. Thanks in advance for any replies, GM

  • Why does loading a html page opens automaically the printer dialog?

    - by Alex
    I have the problem that loading a certain webpage in firefox automatically opens the printer dialog. How is that? Additional information: This only happens on firefox 24.0 on Windows 7. It neither happens on Windows Explorer in Windows 7 nor on Firefox 24 on a Linux system. This also happens when using the firefox safemode, with all add-ons disabled. I cannot post the webpage, since it is not public and restricted. Multiple javascript files are used, but none contains the expression print(). The page content does not contain the phrase 'printer'. It has nothing to do with printing something. This happens sometimes, but not always. I cannot say for sure the URL and/or the content is always identical. I can answer any other questions, like 'Does the page contain this and that...', 'does the URL contain this and that...' Basic question: What could be the reason for the annoying printer pop up?

  • Ruby page loading very very slowly - how should I speed it up?

    - by Elliot
    Hey guys, I'm going to try and describe the code in my view, without actually posting all the garbage: It has a standard shell (header, footer etc. in the layout) this is also where the sub navigation exists which is based on a loop (to find the amount of options) - on this page, we have 6 subnav links. Then in the index view, we have a 3rd level nav - with 3 links that use javascript to link/hide divs on the page. This means each of those original 6 options, all have their own 3'rd level nav, with each of their own 3 div pages. These three pages/divs have the input form for creating a record in rails, and then the other 2 pages show the records in different assortments. ALL of this code lives on one page (aside from the shell). The original sub nav uses a javascript tab solution, to browse through all of it... (this means its about 6 divs, which all contain 4 divs of function - so about 24 heavy divs). Loading it seems to take forever, although after loaded its extremely fast (obviously). My big question, is how should I attack this? I don't know ajax - although I imagine it'd be a good solution for loading the tabs when clicked. Thanks! Elliot
