  • Strange pattern matching with functions instancing Show

    - by Sean D
    So I'm writing a program which returns a procedure for some given arithmetic problem, so I wanted to instance a couple of functions to Show so that I can print the same expression I evaluate when I test. The trouble is that the given code matches (-) to the first line when it should fall to the second. {-# OPTIONS_GHC -XFlexibleInstances #-} instance Show (t -> t-> t) where show (+) = "plus" show (-) = "minus" main = print [(+),(-)] returns [plus,plus] Am I just committing a motal sin printing functions in the first place or is there some way I can get it to match properly? edit:I realise I am getting the following warning: Warning: Pattern match(es) are overlapped In the definition of `show': show - = ... I still don't know why it overlaps, or how to stop it.

  • Potential issue when using memcache session save handler in PHP

    - by Sean
    I have two load balanced web servers, and I'm using the memcache session save handler with the save path pointing to two memcache servers. It's configured with session redundancy set to two (the number of memcache servers). So PHP is writing session data to both memcache servers, and when I take one of the servers down, everything seems to work fine since the session data has been written to both memcache servers. The problem seems to happen when I use the app for a while with only the one memcache server up, and then bring the other one back up. My theory is that the memcache server comes back up, and PHP then starts asking it for session data which isn't there since it was written to the other server while this one was down. Is there any merit to this theory? Should PHP be asking both servers for the session data and maybe there's some other problem?

  • Detectig by how much user has scrolled

    - by Sean
    I have an image pop-up ability on my website (see this screenshot), in order to show users the full resolution picture when they click on a smaller version on the page. This is the current CSS that positions it: div#enlargedImgWrapper { position: absolute; top: 30px; left: 55px; z-index: 999; } The problem now is that if I click on an image further down the page, the window still appears in the top left corner of the page, where I can't see it until I scroll back up. I need it to appear relative to the window, whatever its current position relative to the document is. Note: I don't want to use position: fixed; as some images might be taller than the screen, so I want users to be able to scroll along the image as well. My idea was to use JS to change the top value: var scrollValue = ???; document.getElementById('enlargedImgWrapper').style.top = scrollValue+30 + 'px'; How can I detect by how much the user has scrolled down the page (var scrollValue)? Or is there a 'better' way to do this? Thanks!

  • Any suggestions for improvement on this style for BDD/TDD?

    - by Sean B
    I was tinkering with doing the setups with our unit test specifciations which go like Specification for SUT when behaviour X happens in scenario Y Given that this thing And also this other thing When I do X... Then It should do ... And It should also do ... I wrapped each of the steps of the GivenThat in Actions... any feed back whether separating with Actions is good / bad / or better way to make the GivenThat clear? /// <summary> /// Given a product is setup for injection /// And Product Image Factory Is Stubbed(); /// And Product Size Is Stubbed(); /// And Drawing Scale Is Stubbed(); /// And Product Type Is Stubbed(); /// </summary> protected override void GivenThat() { base.GivenThat(); Action givenThatAProductIsSetupforInjection = () => { var randomGenerator = new RandomGenerator(); this.Position = randomGenerator.Generate<Point>(); this.Product = new Diffuser { Size = new RectangularProductSize( 2.Inches()), Position = this.Position, ProductType = Dep<IProductType>() }; }; Action andProductImageFactoryIsStubbed = () => Dep<IProductBitmapImageFactory>().Stub(f => f.GetInstance(Dep<IProductType>())).Return(ExpectedBitmapImage); Action andProductSizeIsStubbed = () => { Stub<IDisplacementProduct, IProductSize>(p => p.Size); var productBounds = new ProductBounds(Width.Feet(), Height.Feet()); Dep<IProductSize>().Stub(s => s.Bounds).Return(productBounds); }; Action andDrawingScaleIsStubbed = () => Dep<IDrawingScale>().Stub(s => s.PixelsPerFoot).Return(PixelsPerFoot); Action andProductTypeIsStubbed = () => Stub<IDisplacementProduct, IProductType>(p => p.ProductType); givenThatAProductIsSetupforInjection(); andProductImageFactoryIsStubbed(); andProductSizeIsStubbed(); andDrawingScaleIsStubbed(); andProductTypeIsStubbed(); }

  • How to open a document in a separate window from a site map

    - by Sean
    I was hoping to open a document in a menu control using a sitemap. I am using the following code in the sitemap but get an error. I would like to be able to click on the menu item, have it open the sample doc in a new window, but not to have the original page navigate to a new place (essentially to do nothing on the main page.) <siteMapNode url="javascript:widow.open('Sample.doc','SampleName'); return false" title="FAQs" description="FAQs" /> Any idea? Is there some javascript I can use that does not require me to register a function on every page?

  • How to interpret situations where Math.Acos() reports invalid input?

    - by Sean Ochoa
    Hey all. I'm computing the angle between two vectors, and sometimes Math.Acos() returns NaN when it's input is out of bounds (-1 input && input 1) for a cosine. What does that mean, exactly? Would someone be able to explain what's happening? Any help is appreciated! Here's me method: public double AngleBetween(vector b) { var dotProd = this.Dot(b); var lenProd = this.Len*b.Len; var divOperation = dotProd/lenProd; // http://msdn.microsoft.com/en-us/library/system.math.acos.aspx return Math.Acos(divOperation) * (180.0 / Math.PI); }

  • Vim navigation clunkiness

    - by Sean Chambers
    I've committed myself to diving into vim to become faster at writing code for ruby/python and I'm having a hard time navigating around files. Mainly, I'm referring to switching between insert mode and navigation modes. Maybe I'm just not completely used to the editor yet but it feels very awkward to constantly be switching in and out of insert mode. Is this something that will go away with time? Are there any tricks to getting quicker at moving in and out of insert mode?

  • java overloaded method

    - by Sean Nguyen
    Hi, I have an abstract template method: class abstract MyTemplate { public void something(Object obj) { doSomething(obj) } protected void doSomething(Object obj); } class MyImpl extends MyTemplate { protected void doSomething(Object obj) { System.out.println("i am dealing with generic object"); } protected void doSomething(String str) { System.out.println("I am dealing with string"); } } public static void main(String[] args) { MyImpl impl = new MyImpl(); impl.something("abc"); // --> this return "i am dealing with generic object" } How can I print "I am dealing with string" w/o using instanceof in doSomething(Object obj)? Thanks,

  • Rspec > testing database views

    - by Sean McCleary
    How can database views be tested in Rspec? Every scenario is wrapped in a transaction and the data does not look like it is being persisted to the database (MySQL in my case). My view returns with an empty result set because none of the records are being persisted in the transaction. I am validating that the records are not being stored by setting a debug point in my spec and checking my data with a database client while the spec is being debugged. The only way I can think to have my view work would be if I could commit the transaction before the end of the scenario and then clear the database after the scenario is complete. Does anyone know how to accomplish this or is there a better way? Thanks

  • Setting new class variables inside a module

    - by Sean McCleary
    I have a plugin I have been working on that adds publishing to ActiveRecord classes. I extend my classes with my publisher like so: class Note < ActiveRecord::Base # ... publishable :related_attributes => [:taggings] end My publisher is structured like: module Publisher def self.included(base) base.send(:extend, ClassMethods) @@publishing_options = [] # does not seem to be available end module ClassMethods def publishable options={} include InstanceMethods @@publishing_options = options # does not work as class_variable_set is a private method # self.class_variable_set(:@@publishing_options, options) # results in: uninitialized class variable @@publishing_options in Publisher::ClassMethods puts "@@publishing_options: #{@@publishing_options.inspect}" # ... end # ... end module InstanceMethods # results in: uninitialized class variable @@publishing_options in Publisher::InstanceMethods def related_attributes @@publishing_options[:related_attributes] end # ... end end Any ideas on how to pass options to publishable and have them available as a class variable?

  • java template design

    - by Sean Nguyen
    Hi, I have this class: public class Converter { private Logger logger = Logger.getLogger(Converter.class); public String convert(String s){ if (s == null) throw new IllegalArgumentException("input can't be null"); logger.debug("Input = " + s); String r = s + "abc"; logger.debug("Output = " + s); return r; } public Integer convert(Integer s){ if (s == null) throw new IllegalArgumentException("input can't be null"); logger.debug("Input = " + s); Integer r = s + 10; logger.debug("Output = " + s); return r; } } The above 2 methods are very similar so I want to create a template to do the similar things and delegate the actual work to the approriate class. But I also want to easily extends this frame work without changing the template. So for example: public class ConverterTemplate { private Logger logger = Logger.getLogger(Converter.class); public Object convert(Object s){ if (s == null) throw new IllegalArgumentException("input can't be null"); logger.debug("Input = " + s); Object r = doConverter(); logger.debug("Output = " + s); return r; } protected abstract Object doConverter(Object arg); } public class MyConverter extends ConverterTemplate { protected String doConverter(String str) { String r = str + "abc"; return r; } protected Integer doConverter(Integer arg) { Integer r = arg + 10; return r; } } But that doesn't work. Can anybody suggest me a better way to do that? I want to achieve 2 goals: 1. A template that is extensible and does all the similar work for me. 2. I ant to minimize the number of extended class. Thanks,

  • focusout not triggering when clicking on another selector with a click

    - by Sean
    I have 2 divs that each have clicks bound to them. when you click on a div a form is displayed (in another div) that allows you to set properties specific to the div that is clicked. I'm using focusout to save the properties to a data object. everything is working perfectly except when i click on the other div. it seems that the click handler on the other div cancels out the focusout of the form field. Has anyone else experienced this? is so what is the proper way to overcome this?

  • Faster s3 bucket duplication

    - by Sean McCleary
    I have been trying to find a better command line tool for duplicating buckets than s3cmd. s3cmd can duplicate buckets without having to download and upload each file. The command I normally run to duplicate buckets using s3cmd is: s3cmd cp -r --acl-public s3://bucket1 s3://bucket2 This works, but it is very slow as copies each file via the API one at a time. If s3cmd could run in parallel mode, I'd be very happy. Are there other options available as a command line tools or code that people use to duplicate buckets that are faster than s3cmd?

  • C# Type comparison

    - by Sean.C
    This has me pooped, is there any reason the following: public abstract class aExtension { public abstract bool LoadExtension(Constants c); // method required in inherit public abstract string AppliesToModule // property required in inherit { get; } public abstract string ExtensionName // property required in inherit { get; } public abstract string ExtensionDescription // property required in inherit { get; } } public class UK : aExtension { public override bool LoadExtension(Constants c) { return true; } public override string AppliesToModule { get { return "string"; } } public override string ExtensionName { get { return "string"; } } public override string ExtensionDescription { get { return "string"; } } } would return false for the following expressions: bool a = t.IsAssignableFrom(aExtension)); bool b = t.BaseType.IsAssignableFrom(aExtension)); bool c = typeof(aExtension).IsAssignableFrom(t); bool d = typeof(aExtension).IsAssignableFrom(t.BaseType); bool e = typeof(aExtension).IsSubclassOf(t); bool f = typeof(aExtension).IsSubclassOf(t.BaseType); bool g = t.IsSubclassOf(typeof(aExtension)); bool h = t.BaseType.IsSubclassOf(typeof(LBT.AdMeter.aExtension)); bool i = t.BaseType.Equals(typeof(aExtension)); bool j = typeof(aExtension).Equals(t.BaseType); T is the reflected Type from the calss UK. Stange thing is i do the exact same thing just on an external assembly in the same application and it works as expected...

  • Firefox all but freezes during large file upload; Ajax progress bar infeasible; IE6 works fine

    - by Sean
    I want to provide a progress bar for my users who upload very large files. I did some reading and implemented what should be a pretty straightforward solution: I have a <form> element that contains an file input element; its target is set to the ID of a hidden iframe. On the server side, there's some Spring magic that attaches an object to the user's session; the progress of the upload can be queried from this object. After submitting the form, I start a repeating Ajax call using setInterval that queries the server for the percent-complete using the aforementioned session object. The call repeats every half-second, skipping the Ajax call if the previous call has not yet completed. I use the data from the call to update the width of an onscreen element. When the server call reports that the upload is complete, I clear the interval timer. I created a 100-megabyte file and uploaded it using my interface. This is using Firefox 3.6.3. What I found is that although the upload takes 20-25 seconds, the progress bar doesn't get updated until the very end. Moreover, the entire browser is basically frozen until the upload completes. I assumed that my method must be flawed, but I tried the same page using IE6, and was utterly amazed when it behaved as I had designed it to--the progress bar got updated every half second, and the whole upload only took about 15 seconds, much faster than Firefox. I don't have many add-ons installed, but I tried disabling Firebug and restarting my browser. This marginally improved the performance--I got perhaps a single additional progress bar update mid-upload--but still far from acceptable. Can anyone tell me what I can do to bring Firefox's performance up to the level of IE6? Ugh, I can't believe I actually typed that. EDIT: I just tried uploading a large file from a Firefox 3.6.3 browser on a different machine than the one that's running my web server, and it worked fine. Huh.

  • C# Function Inheritance--Use Child Class Vars with Base Class Function

    - by Sean O'Connor
    Good day, I have a fairly simple question to experienced C# programmers. Basically, I would like to have an abstract base class that contains a function that relies on the values of child classes. I have tried code similar to the following, but the compiler complains that SomeVariable is null when SomeFunction() attempts to use it. Base class: public abstract class BaseClass { protected virtual SomeType SomeVariable; public BaseClass() { this.SomeFunction(); } protected void SomeFunction() { //DO SOMETHING WITH SomeVariable } } A child class: public class ChildClass:BaseClass { protected override SomeType SomeVariable=SomeValue; } Now I would expect that when I do: ChildClass CC=new ChildClass(); A new instance of ChildClass should be made and CC would run its inherited SomeFunction using SomeValue. However, this is not what happens. The compiler complains that SomeVariable is null in BaseClass. Is what I want to do even possible in C#? I have used other managed languages that allow me to do such things, so I certain I am just making a simple mistake here. Any help is greatly appreciated, thank you.

  • Can I use the emacs keyboard macro counter as a command prefix?

    - by Sean M
    I'm working on a project in emacs where I'd like to use a keyboard macro that changes slightly with each iteration. When I saw the keyboard macro counter in the manual, that looked like exactly what I needed - but as far as I can tell, that inserts an incrementing number into the current buffer. I want to use an incrementing number as a prefix to another command. For example, instead of inserting 3 into the buffer on the third execution of the macro, I'd like to be able to execute C-u 3 M-x my-command, followed by C-u 4 M-x my-command on the next iteration. Is there way to create a keyboard macro that does this? My specific task is "zipping" two blocks of text in the same buffer together, but even if there's an alternative way to do that specific thing, it'd be good to know the answer to the general question.
