  • Rails 3: config/initializers errors for gem configuration

    - by neezer
    I'm trying to setup this plugin (Crumble), and the docs say I need to add a configuration file for the plugin in config/initializers/ like this (breadcrumb.rb): Breadcrumb.configure do ... end I add in my directives in that block, and reloaded the page, and I'm immediately greeted with a Passenger error: uninitialized constant Breadcrumb What am I missing here? gem list shows Crumble as installed, and if I launch IRB I can require 'crumble' successfully. I remember doing this just fine in Rails 2.3.5. Here's my setup: rails 3.0.0.beta3 ruby 1.9.1p378 (via RVM) passenger 2.2.11 (with Apache2) crumble 0.1.2 I've been trying to read the Rails 3 release notes to see if they've changed anything that would affect this, but so far I haven't found anything to suggest that the above shouldn't work. I'd appreciate any guidance you could spare me!

  • Regex to validate SMTP Responses?

    - by Alix Axel
    I'm writing a regular expression that can interactively validate SMTP responses codes, once the SMTP dialog is completed it should pass the following regex (some parentheses added for better readability): ^(220)(250){3,}(354)(250)(221)$ Or with(out) authentication: ^(220)(250)((334){2}(235))?(250){2,}(354)(250)(221)$ I'm trying to do rewrite the above regexes so that I can interactively check if the dialog is going as expected, otherwise politely send a QUIT command and close the connection saving bandwidth and time, but I'm having a hard time writing an optimal regex. So far I've managed to come up with: ^(220(250(334(235(250(354(250(221)?)?)?){0,})?){0,2})?)?$ Which, besides only matching authenticated connections, has some bugs... For instance, it matches: 220250334235250354250221 220250334334235250354250221 I've also tried the following modification: ^(220(250)?)?((334(235)?){2})?(250(354(250(221)?)?)?){0,}$ This one accepts non-authenticated responses but it fails to match 220250334 and wrongly matches 220250334334235250354250221 (at least 2 250 are needed before the 354 response code). Can someone help me out with this? Thanks in advance.

  • How to check function parameters in Go

    - by deamon
    Guava Preconditions allows to check method parameters in Java easily. public void doUsefulThings(Something s, int x, int position) { checkNotNull(s); checkArgument(x >= 0, "Argument was %s but expected nonnegative", x); checkElementIndex(position, someList.size()); // ... } These check methods raise exceptions if the conditions are not met. Go has no exceptions but indicates errors with return values. So I wonder how an idiomatic Go version of the above code would look like.

  • bash script to delete old deployments

    - by benjwarner
    I have a directory where our deployments go. A deployment (which is itself a directory) is named in the format: <application-name>_<date> e.g. trader-gui_20091102 There are multiple applications deployed to this same parent directory, so the contents of the parent directory might look something like this: trader-gui_20091106 trader-gui_20091102 trader-gui_20091010 simulator_20091106 simulator_20091102 simulator_20090910 simulator_20090820 I want to write a bash script to clean out all deployments except for the most current of each application. (The most current denoted by the date in the name of the deployment). So running the bash script on the above parent directory would leave: trader-gui_20091106 simulator_20091106 Any help would be appreciated.

  • 'System.Windows.Data.MultiBinding' is not a valid value for property 'Text'.

    - by chaiguy
    I'm trying to write a custom MarkupExtension that allows me to use my own mechanisms for defining a binding, however when I attempt to return a MultiBinding from my MarkupExtension I get the above exception. I have: <TextBlock Text="{my:CustomMarkup ...}" /> CustomMarkup returns a MultiBinding, but apparently Text doesn't like being set to a MultiBinding. How come it works when I say: <TextBlock> <TextBlock.Text> <MultiBinding ... /> </TextBlock.Text> </TextBlock> But it doesn't work the way I'm doing it?

  • Toubleshooting mapkit performance

    - by brettr
    I'm plotting over 500 points on a map using mapkit. Zooming is a little jittery compared to the native google map app. I've discovered what is causing the slowness. I'm adding custom annotations so that I can later add different pin colors and buttons for detail views: - (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(AddressNote *) annotation { MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentlocation"]; annView.pinColor = MKPinAnnotationColorGreen; annView.animatesDrop=TRUE; annView.canShowCallout = YES; annView.calloutOffset = CGPointMake(-5, 5); return annView; } If I comment out the above code, everything works fine. Very smooth with zooming in/out. Should I be adding annotations differently to boost performance?

  • Need to convert this for loop to a while loop

    - by Bragaadeesh
    Hi guys, I solved a problem recently. But I have this one piece of code where I dont utilize the for loop initialization and condition check. It looks a bit odd that way for a for loop. I want to convert it into a while loop. Please help me do it. I tried many times, but somewhere something is missing. for(;;current =(current+1)%n){ if(eliminated[current%n]){ continue; }else{ inkiPinki++; if(inkiPinki == m){ eliminated[current%n] = true; printStatus(eliminated, people); remainingGuys--; break; } } } In the above code eliminiated[index] is a boolean.

  • Iphone SDk inString Function

    - by Skeep
    Hi All, Im trying to write a method that will pull out the ID from a URI String. My code below seems inefficient, what would be a better way of finding the id string? NSString *aID = [[[NSString alloc] initWithString:@"http://www.example.com/id368907840?mt=8&uo=4"] autorelease]; NSArray *arrStr = [aID componentsSeparatedByString:@"/id"]; aID = [arrStr objectAtIndex:1]; arrStr = [aID componentsSeparatedByString:@"?mt="]; aID = [arrStr objectAtIndex:0]; The above leaves me with the NSString = 368907840

  • Can someone explain this "endian-ness" function for me?

    - by Mike
    Write a program to determine whether a computer is big-endian or little-endian. bool endianness() { int i = 1; char *ptr; ptr = (char*) &i; return (*ptr); } So I have the above function. I don't really get it. ptr = (char*) &i, which I think means a pointer to a character at address of where i is sitting, so if an int is 4 bytes, say ABCD, are we talking about A or D when you call char* on that? and why? Would some one please explain this in more detail? Thanks. So specifically, ptr = (char*) &i; when you cast it to char*, what part of &i do I get?

  • Android ndk build mysteriously failing under cygwin with "Error 126"

    - by Jan Hudec
    I have a JNI application built by ndk-build (using Android NDK r5b and cygwin make 3.81). The build usually works, by occasionally fails with: ... Compile++ thumb : components <= Component.cpp make: *** [/c/.hudson/jobs/Nightly/workspace/application/obj/local/armeabi/objs/components/Component.o] Error 126 make: Leaving directory `/c/.hudson/jobs/Nightly/workspace/application/obj/local/armeabi/objs/components' There is no other error. Make than exits with status 2. It happens in different file each time (the name above is anonymized). It seems to happen more often with parallel builds, but sometimes happens with non-parallel builds too. Does anybody have an idea what it might be or at least how to debug it?

  • Need to read a file, search for some data and output the data using PHP

    - by Kyle
    Hello...I am new to PHP (never really used it before tonight) and I need to use a PHP script to read the contents of a file on my website (http://kylemills.net/Geocaching/BadgeGen/MacroFiles/BadgeGenBeta.gsk) and then take some specific varying data and output it. For example: If my file contains the text: random text Here is some text #There is some text here too $Version = "V2.2.23 Beta" random text #some more text $Text="some text" If the above was the contents of my file, I need the script to return "V2.2.23 Beta" (without quotes). The idea is that as I update the file, the version changes and I want this to be reflected across my site. I am sorry if I don't make any sense...any help would be appreciated :) -Thanks so much, Kyle

    - by Dimitree
    I have a Document class that loads variables from Facebook with the use of stage.loaderInfo var connect:FacebookConnectObject = new FacebookConnectObject( facebook, API_KEY, this.stage.loaderInfo ); But when I change the Document class (with another one responsible for the layout of my app), and try call the above from a movieclip that exists in my application with the use: var facebook_class:FacebookAp = new FaceBppkApp addChild(facebook_class) I get error TypeError: Error #1009: Cannot access a property or method of a null object reference. I believe the error comes fro this line this.stage.loaderInfo since I changed the scope... How I am supposed to fix that?

  • What's the best way to move "a child up" in a C# XmlDocument?

    - by Mike
    Hi everyone, Given an xml structure like this: <garage> <car>Firebird</car> <car>Altima</car> <car>Prius</car> </garage> I want to "move" the Prius node "one level up" so it appears above the Altima node. Here's the final structure I want: <garage> <car>Firebird</car> <car>Prius</car> <car>Altima</car> </garage> So given the C# code: XmlNode priusNode = GetReferenceToPriusNode() What's the best way to cause the priusNode to "move up" one place in the garage's child list? Thanks! -Mike

  • Why will this code compile using ifort compiler and not when using gfortran compiler? Help!

    - by CuriousCompiler
    I'm rewriting some code to make a program compile with the gfortran compiler as opposed to ifort compiler I usually use. The code follows: _Subroutine SlideBits (WORD, BITS, ADDR) Implicit None Integer(4) WORD Integer(4) BITS Integer(4) ADDR Integer(4) ADDR1 ADDR1 = 32 - ADDR WORD = (WORD .And. (.Not.ISHFT(1,ADDR1))) .Or. ISHFT(BITS,ADDR1) End_ When I compile the above code using the gfortran compiler, I recieve this error: WORD = (WORD .And. (.Not.ISHFT(1,ADDR1))) .Or. ISHFT(BITS,ADDR1) Error: Operand of .NOT. operator at (1) is INTEGER(4) All three of the variables coming into the subroutine are integers. I've looked around a bit and the gfortran wiki states that the gfortran compiler should be able to handle logical statments being applied to integer values. Several other sites I've visited either quote from the gnu wiki or agree with it. This is the first time I've seen this error as the Intel Fortran compiler (ifort) I normally use compiles cleanly.

  • IAR Embedded Workbench - setting endian-ness of variable

    - by Seidleroni
    I'm using IAR Embedded Workbench for ARM (ARM7TDMI-S) and the majority of my work is done using little-endian format. However, I saw in the manual that I can do something like : __big_endian int i, j; to declare those two variables as big endian (while the rest of the app as little endian). This seems like a fantastic feature, but when I try to compile, I always get the errror: Error[Pa002]: the type attribute "__big_endian" is not allowed on this declaration. The big endian line above is copied directly from the manual, but it does not work. This is a great feature of the compiler and would make life a big easier. Any ideas how to get it working? I have my language conformance set to 'Allow IAR extensions' on the C/C++ Compiler options tab on the IDE options.

  • Completion block not being called. How to check validity?

    - by HCHogan
    I have this method which takes a block, but that block isn't always called. See the method: - (void)updateWithCompletion:(void (^)(void))completion { [MYObject myMethodWithCompletion:^(NSArray *array, NSError *error) { if (error) { NSLog(@"%s, ERROR not nil", __FUNCTION__); completion(); return; } NSLog(@"%s, calling completion %d", __FUNCTION__, &completion); completion(); NSLog(@"%s, finished completion", __FUNCTION__); }]; } I have some more NSLogs inside completion. Sometimes this program counter just blows right past the call to completion() in the code above. I don't see why this would be as the calling code always passes a literal block of code as input. If you're curious of the output of the line containing the addressof operator, it's always something different, but never 0 or nil. What would cause completion not to be executed?

  • AVR Analog Comparator + Internal Pullup?

    - by vicatcu
    I have what I hope is a simple question pertaining to the Atmel AVR microcontrollers. So I want to use the ATTiny85's Analog Comparator to determine if a signal is above or below a threshold. This signal is normally "floating" and grounded when "active" (i.e. it's an active low - open collector signal). If I enable the pullup on the input pin (which is also the comparator input) by doing: DDRB = 0x00; // DDRB.1 = 0 = input PORTB = 0xFF; // PORTB.1 = 1 = internal pullup enabled If i use the analog comparator and select PORTB.1 as AIN1 will the internal pullup be applied to my input signal? I'm hoping someone has personal experience to verify this behavior. Hope this question isn't too 'hardware-oriented' for stack-overflow. Thanks!

  • Is there a recommended way to use the Observer pattern in MVP using GWT?

    - by Tomislav Nakic-Alfirevic
    I am thinking about implementing a user interface according to the MVP pattern using GWT, but have doubts about how to proceed. These are (some of) my goals: - the presenter knows nothing about the UI technology (i.e. uses nothing from com.google.*) - the view knows nothing about the model or the presenter - the model knows nothing of the view or the presenter (...obviously) I would place an interface between the view and the presenter and use the Observer pattern to decouple the two: the view generates events and the presenter gets notified. What confuses me is that java.util.Observer and java.util.Observable are not supported in GWT. This suggests that what I'm doing is not the recommended way to do it, as far as GWT is concerned, which leads me to my questions: what is the recommended way to implement MVP using GWT, specifically with the above goals in mind? How would you do it?

  • How to dynamically load & unload a TinyMCE Plugin

    - by Matt Simpson
    Does anyone know if there is a way I can dynamically load and unload a TinyMCE plugin after TinyMCE has already been loaded? Specifically, I'm thinking about asking the user whether or not they wish to load the fullpage plugin using perhaps a radio button or something above TinyMCE: <input type="radio" name="fullpage" value="enabled" /> Enable Fullpage Plugin<br /> <input type="radio" name="fullpage" value="disabled" /> Disable Fullpage Plugin<br /> <textarea name="tinymce" id="tinymce">...</textarea> I suppose I could destroy the original instance and load a new config (one for enabled / one for disabled), but it seems as though there should be a more elegant way of loading and unloading plugins.

  • Unable to get the DspStatus Field in the Task document properties.

    - by Pari
    Hi, I am using Interop.Domino.dll API to read the NSF file and able to read the properties of the Task Document. When i view the Task Document properties in the Lotus Notes, i am able to view the Status Field, Importance Field and few others, but when i programatically dump all the Field Names and their values i am unable to get few of them as mentioned above. So, how to get all the Field Names and their values as i iterate through all the document properties. Is this the problem of IBM Lotus Notes Application or the Domino API ? Here is my sample code to iterate the TODO document properties : object[] TaskItems = docTodoDoc.Items as object[]; foreach (NotesItem objItem in TaskItems) { m_objLogFile.Debug(objItem.Name + " - "); m_objLogFile.Debug("Values :: " + ((object[])docTodoDoc.GetItemValue(objItem.Name))[0] as String); } Please help me out to over come this issue as i need to access the status value of the TODO Item from the NSF file. Thanks.
