• Compilier optimization of repeated accessor calls C#

  - by apocalypse9

  I've found recently that for some types of financial calculations that the following pattern is much easier to follow and test especially in situations where we may need to get numbers from various stages of the computation. public class nonsensical_calculator { ... double _rate; int _term; int _days; double monthlyRate { get { return _rate / 12; }} public double days { get { return (1 - i); }} double ar { get { return (1+ days) /(monthlyRate * days) double bleh { get { return Math.Pow(ar - days, _term) public double raar { get { return bleh * ar/2 * ar / days; }} .... } Obviously this often results in multiple calls to the same accessor within a given formula. I was curious as to whether or not the compiler is smart enough to optimize away these repeated calls with no intervening change in state, or whether this style is causing a decent performance hit. Further reading suggestions are always appreciated

• Rails - operation outside of a rollback

  - by Brian Armstrong

  I have a before_create filter that checks if people are posting too many comments. If they are I want to flag their account. class Comment < ActiveRecord::Base before_create :check_rate_limit def check_rate_limit comments_in_last_minute = self.user.comments.count(:conditions => ["comments.created_at > ?", 1.minute.ago]) if comments_in_last_minute > 2 user.update_attribute :status, "suspended" return false end true end end The before filter returns false to stop the comment from being created. The problem is that this triggers a ROLLBACK which also undoes the changes I made to the user model. What's the correct pattern to accomplish this? Specifically: running a check each time an object is created and being able to edit another model if the check fails.

• Asp.Net MVC style routing in Django

  - by Andrew Hanson

  I've been programming in Asp.Net MVC for quite some time now and to expand a little bit beyond the .Net world I've recently began learning Python and Django. I am enjoying Django but one thing I am missing from Asp.Net MVC is the automatic routing from my urls to my controller actions. In Asp.Net MVC I can build much of my application using this single default route: routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); In Django I've found myself adding an entry to urls.py for each view that I want to expose which leads to a lot more url patterns than I've become used to in Asp.Net MVC. Is there a way to create a single url pattern in Django that will handle "[Application]/view/[params]" in a way similar to Asp.Net MVC? Perhaps at the main web site level?

• How reusable should ViewModel classes be?

  - by stiank81

  I'm working on a WPF application, and I'm structuring it using the MVVM pattern. Initially I had an idea that the ViewModels should be reusable, but now I'm not too sure anymore. Should I be able to reuse my ViewModels if I need similar functionality for a WinForms application? Silverlight doesn't support all things WPF does - should I be able to reuse for Silverlight applications? What if I want to make a Linux GUI for my application. Then I need the ViewModel to build in Mono - is this something I should strive for? And so on.. So; should one write ViewModel classes with one specific View in mind, or think of reusability?

• ASP.NET MVC on IIS6

  - by Seb Nilsson

  Where can I find some good pointers on best practices for running ASP.NET MVC on IIS6? I haven't seen any realistic options for web-hosts who provide IIS7-hosting yet. Mostly because I don't live in the U.S. So I was wondering on how you best build applications in ASP.NET MVC and make it easily available to deploy on both IIS6 and IIS7. Keep in mind that this is for standard web-hosts, so there is no access to ISAPI-filters or special settings inside IIS6. Are there anything else one should think about when developing ASP.NET MVC-applications to target IIS6? Any functions that doesn't work? UPDATE: One of the bigger issues is the thing with routes. The pattern {controller}/{action} will work on IIS7, but not IIS6 which needs {controller}.mvc/{action}. So how do I make this transparent? Again, no ISAPI and no IIS-settings, please.

• emacs23 pops up debugger way too frequently

  - by werner r.

  Since I've upgraded to Ubuntu lucid and emacs23, Emacs pops up the debugger in situations, where emacs22 does not. For example, when hitting C-c C-c in org-mode, emacs22 simply states can do nothing useful at this location, whereas in emacs23 the debugger shows up. Debugger entered--Lisp error: (error "C-c C-c can do nothing useful at this location") signal(error ("C-c C-c can do nothing useful at this location")) error("C-c C-c can do nothing useful at this location") org-ctrl-c-ctrl-c(nil) call-interactively(org-ctrl-c-ctrl-c nil nil) That only illustrates the pattern -- the behavior is not limited to org-mode. Occurring every 3 minutes, it really annoys me. How can I prevent it? I've already tried to stop this using debug-on-error and stack-trace-on-error: it didn't work.

• Javascript regex only matching entire url as typing

  - by dt

  I'm trying to use javascript to find all URLs in a textarea as the person is typing (onkeyup). The problem that I'm having is in finding a regex to match the entire URL, I need it only to match all the URL's in the text area that are complete URLs. All of the existing regex expressions that I find through Google and through my own experiementing seem to match as soon as the user has typed the first part of the pattern. So, for example, if I'm typing and then start to type http://w, all of a sudden, it will match. I need to find a regex that will match and return an array of all the urls that are in the textarea, while also not matching unless the person has completed typing the full URL. Hopefully that makes sense! Thank you!

• How do I remove those rotation artefacts from my CATiledLayer?

  - by Felix

  Hello all, I have a CATiledLayer into which I render content in the following method - (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx I used the QuartzDemo code to draw a pattern. This works very well until I apply a rotation transform to the layer's parentLayer (a UIView): rotated: These zigzag artefacts become worse when I start drawing lines and texts into the CATiledLayer. I applied the transform as follows (I also tried using an affine transform on the view itself): self.containerView.layer.transform = CATransform3DMakeRotation(angleRadians, 0.0f, 0.0f, 1.0f); I transform the containerView rather than the layer itself, as I have several layers in that view that I would like to rotate at the same time without changing the relative positions. I did not have problems when rotating UIImageViews in the past. Is there a way that I can rotate the CATiledLayer without these problems? Any help would be greatly appreciated. Yours, Felix

• IDisposable: is it necessary to check for null on finally {}?

  - by BlackTigerX

  In most examples that you find on the web when explicitly not using "using", the pattern looks something like: SqlConnection c = new SqlConnection(@"..."); try { c.Open(); ... } finally { if (c != null) //<== check for null c.Dispose(); } If you do use "using" and look at the generated IL code, you can see that it generates the check for null L_0024: ldloc.1 L_0025: ldnull L_0026: ceq L_0028: stloc.s CS$4$0000 L_002a: ldloc.s CS$4$0000 L_002c: brtrue.s L_0035 L_002e: ldloc.1 L_002f: callvirt instance void [mscorlib]System.IDisposable::Dispose() L_0034: nop L_0035: endfinally I understand why the IL gets translated to check for null (doesn't know what you did inside the using block), but if you're using try..finally and you have full control of how the IDisposable object gets used inside the try..finally block, do you really need to check for null? if so, why?

• Parsing a DateTime String into Custom Date and Time Format String

  - by AMissico

  With .NET, I have "Thursday, April 10, 2008 1:30:00 PM" and I want "dddd, dd MMMM, yyyy h:m:s t", "6:09:01 PM" and want ""hh:mm:ss tt", "Fri 29 Aug" and want "ddd d MMM", and so on. It seems I should be able to use DateTimeFormatInfo in some way. I figured I can format the date with each pattern returned by GetAllDateTimePatterns, and when the original date string and the formated date string match then I have the format. Yet, I want to generate custom formats, not the standard formats. I want the format string. I do not want the date. I have both the DateTime value and the formatted string value for the date. I need <formatString> as in ToString(<formatString>).

• iPhone -- initialization partly by NSKeyedUnarchiver and partly by other means

  - by William Jockusch

  I have an object myObj, which is an instance of a class MyClass. Some of its instance variables always have their initial values passed in by the calling code. Other instance variables will be initialized in one of two ways. For an instanceArray of type NSMutableArray, the possibilities are either instanceArray = [[NSMutableArray alloc]init]; or instanceArray = [someKeyedUnarchiver decodeObjectForKey: kInstanceArrayKey]; The calling code should determine which of the above will be used. Any particular design pattern I should prefer?

• Recommend a PHP framework for new PHP programmer

  - by webworm

  Hi All, I am fairly new to PHP but not programming in general. I was hoping I could get some suggestions on the best type of PHP framework to start with considering my basic experience with PHP. I have a .NET and ASP.NET background and I am familiar with the MVC design pattern. I would prefer to start with a framework that makes logical design easier but does not generate all the code for you. I have read some like the Zend framework for this. Opinions?

• When to use MVP in Windows Forms .net application?

  - by Janalopa

  I am familiar with MVC/MVP though my question is simple, I'm about to program a simple Instant Messaging software when the engine and communication part is an open API. so my software will have about 3 forms, a splash screen with login details, the options form and a main form with all the functionality like: Friends List, Send message, Received messages (tabbed), search user, etc. In UI perspective, its important for the GUI to be in 1 form in my application. So my question is, for the only complicated form that I'm going to have, is it necessary to implement an MVP design pattern or in this case its better to just go straight forward and put all the logic in 1 place? THANKS Janalopa!

• SQL Server won't perform regular expression validation on XML column

  - by Kirk Broadhurst

  Hi I have an XML column in my table which contains this xsd snippet: <xsd:element name="Postcode" minOccurs="0"> <xsd:simpleType> <xsd:restriction base="xsd:string"> <xsd:pattern value="^[0-9]{4}$" /> </xsd:restriction> </xsd:simpleType> </xsd:element> The regular expression should require a string containing 4 numerical digits. It validates perfectly in Visual Studio and is a correct regular expression. SQL Server, on the other hand, won't accept it. The error message I receive is: XML Validation: Invalid simple type value: '1234'. Location: / * : Donor[1]/*:Postcode[1]. I have an email address regex working fine, but can't get this simple numerical regex to work.

• Best practices for handling math calculations in a flash project?

  - by VideoDnd

  I'm building a Flash project where it needs to handle some math, like an acceleration formula. My director has recommended a design pattern where I include the calculations directly in the flash object, but that doesn't seem like it's very good OOP. What's the best practice for calculations in Flash? Should it be a separate object, so I can keep the "non-Flash" parts together and out of the way? What are people's experiences with including it inline vs. keeping it separate?

• Traditional IO vs memory-mapped

  - by Senne

  I'm trying to illustrate the difference in performance between traditional IO and memory mapped files in java to students. I found an example somewhere on internet but not everything is clear to me, I don't even think all steps are nececery. I read a lot about it here and there but I'm not convinced about a correct implementation of neither of them. The code I try to understand is: public class FileCopy{ public static void main(String args[]){ if (args.length < 1){ System.out.println(" Wrong usage!"); System.out.println(" Correct usage is : java FileCopy <large file with full path>"); System.exit(0); } String inFileName = args[0]; File inFile = new File(inFileName); if (inFile.exists() != true){ System.out.println(inFileName + " does not exist!"); System.exit(0); } try{ new FileCopy().memoryMappedCopy(inFileName, inFileName+".new" ); new FileCopy().customBufferedCopy(inFileName, inFileName+".new1"); }catch(FileNotFoundException fne){ fne.printStackTrace(); }catch(IOException ioe){ ioe.printStackTrace(); }catch (Exception e){ e.printStackTrace(); } } public void memoryMappedCopy(String fromFile, String toFile ) throws Exception{ long timeIn = new Date().getTime(); // read input file RandomAccessFile rafIn = new RandomAccessFile(fromFile, "rw"); FileChannel fcIn = rafIn.getChannel(); ByteBuffer byteBuffIn = fcIn.map(FileChannel.MapMode.READ_WRITE, 0,(int) fcIn.size()); fcIn.read(byteBuffIn); byteBuffIn.flip(); RandomAccessFile rafOut = new RandomAccessFile(toFile, "rw"); FileChannel fcOut = rafOut.getChannel(); ByteBuffer writeMap = fcOut.map(FileChannel.MapMode.READ_WRITE,0,(int) fcIn.size()); writeMap.put(byteBuffIn); long timeOut = new Date().getTime(); System.out.println("Memory mapped copy Time for a file of size :" + (int) fcIn.size() +" is "+(timeOut-timeIn)); fcOut.close(); fcIn.close(); } static final int CHUNK_SIZE = 100000; static final char[] inChars = new char[CHUNK_SIZE]; public static void customBufferedCopy(String fromFile, String toFile) throws IOException{ long timeIn = new Date().getTime(); Reader in = new FileReader(fromFile); Writer out = new FileWriter(toFile); while (true) { synchronized (inChars) { int amountRead = in.read(inChars); if (amountRead == -1) { break; } out.write(inChars, 0, amountRead); } } long timeOut = new Date().getTime(); System.out.println("Custom buffered copy Time for a file of size :" + (int) new File(fromFile).length() +" is "+(timeOut-timeIn)); in.close(); out.close(); } } When exactly is it nececary to use RandomAccessFile? Here it is used to read and write in the memoryMappedCopy, is it actually nececary just to copy a file at all? Or is it a part of memorry mapping? In customBufferedCopy, why is synchronized used here? I also found a different example that -should- test the performance between the 2: public class MappedIO { private static int numOfInts = 4000000; private static int numOfUbuffInts = 200000; private abstract static class Tester { private String name; public Tester(String name) { this.name = name; } public long runTest() { System.out.print(name + ": "); try { long startTime = System.currentTimeMillis(); test(); long endTime = System.currentTimeMillis(); return (endTime - startTime); } catch (IOException e) { throw new RuntimeException(e); } } public abstract void test() throws IOException; } private static Tester[] tests = { new Tester("Stream Write") { public void test() throws IOException { DataOutputStream dos = new DataOutputStream( new BufferedOutputStream( new FileOutputStream(new File("temp.tmp")))); for(int i = 0; i < numOfInts; i++) dos.writeInt(i); dos.close(); } }, new Tester("Mapped Write") { public void test() throws IOException { FileChannel fc = new RandomAccessFile("temp.tmp", "rw") .getChannel(); IntBuffer ib = fc.map( FileChannel.MapMode.READ_WRITE, 0, fc.size()) .asIntBuffer(); for(int i = 0; i < numOfInts; i++) ib.put(i); fc.close(); } }, new Tester("Stream Read") { public void test() throws IOException { DataInputStream dis = new DataInputStream( new BufferedInputStream( new FileInputStream("temp.tmp"))); for(int i = 0; i < numOfInts; i++) dis.readInt(); dis.close(); } }, new Tester("Mapped Read") { public void test() throws IOException { FileChannel fc = new FileInputStream( new File("temp.tmp")).getChannel(); IntBuffer ib = fc.map( FileChannel.MapMode.READ_ONLY, 0, fc.size()) .asIntBuffer(); while(ib.hasRemaining()) ib.get(); fc.close(); } }, new Tester("Stream Read/Write") { public void test() throws IOException { RandomAccessFile raf = new RandomAccessFile( new File("temp.tmp"), "rw"); raf.writeInt(1); for(int i = 0; i < numOfUbuffInts; i++) { raf.seek(raf.length() - 4); raf.writeInt(raf.readInt()); } raf.close(); } }, new Tester("Mapped Read/Write") { public void test() throws IOException { FileChannel fc = new RandomAccessFile( new File("temp.tmp"), "rw").getChannel(); IntBuffer ib = fc.map( FileChannel.MapMode.READ_WRITE, 0, fc.size()) .asIntBuffer(); ib.put(0); for(int i = 1; i < numOfUbuffInts; i++) ib.put(ib.get(i - 1)); fc.close(); } } }; public static void main(String[] args) { for(int i = 0; i < tests.length; i++) System.out.println(tests[i].runTest()); } } I more or less see whats going on, my output looks like this: Stream Write: 653 Mapped Write: 51 Stream Read: 651 Mapped Read: 40 Stream Read/Write: 14481 Mapped Read/Write: 6 What is makeing the Stream Read/Write so unbelievably long? And as a read/write test, to me it looks a bit pointless to read the same integer over and over (if I understand well what's going on in the Stream Read/Write) Wouldn't it be better to read int's from the previously written file and just read and write ints on the same place? Is there a better way to illustrate it? I've been breaking my head about a lot of these things for a while and I just can't get the whole picture..

But there is a issue as before clicking "Save and Send Invitations" button of Lotus notes 8.5, i am able to view the "RepeatForUnit" field from document property and based on its value i am identifying the Recurrence type like (D: for daily, W: for Weekly, M: for monthly etc). But, After clicking on the "Save and Send Invitations" button, the Recurrence is getting saved but after that, i am unable to get the "RepeatForUnit" field in Document Properties. Kindly help me, how to identify the Recurrence type and the related fields. Note: I am using Domino.dll using C#.

• Recursive Syntax in Oslo

  - by Kevin Lawrence

  I'm writing my first DSL with Oslo and I am having a problem with a recursive syntax definition. The input has sections which can contain questions or other sections recursively (composite pattern) like this: Section: A Question: 1 Question: 2 Section: B Question: 1 End End My definition for a Section looks like this syntax Section = "Section:" id:Text body:(SectionBody)* "End Section"; Which works (but doesn't handle recursive sections) if I define SectionBody like this syntax SectionBody = (Question); but doesn't work with a recursive definition like this syntax SectionBody = (Question | Section); What am I missing?

• How do I create a reusable WF sequential workflow?

  - by djgiard

  I have two customers that have the same workflow (Create file -transport file - wait for response - send response to internal team); however the implementation of each step is different for each customer. For example, one customer requires a flat file to be sent via SFTP, while the other customer requires an XML file to be sent via FTP. I'd like to create a sequential workflow, using Microsoft Workflow Foundation (WF) and reuse this workflow for multiple vendors. Each action's call to an external module can use the same interface, but a different concrete implementation. However, I'm unfamiliar with WF and I'm not sure how to implement this. Can someone point me to the proper way to use this pattern? Will it make a difference whether I choose WF 3.5 or WF 4.0? Thank you.

• How do I view application directories and directories that begin with dot in Netbeans on OSX?

  - by moorej

  How do I view directories that begin with dot and how do I browse application directories in Netbeans? I can't seem to view directories that begin with a "dot" through the open file dialog in Netbeans. Similarly, I can't browse any application directory e.g. File-Open File-"someapp.app". Attempting to browse "someapp.app" gives the error "someapp.app is a directory". Altering or removing the regex under Preferences-Miscellaneous-File-Ignored Files Pattern has no effect; directories that begin with dot stay invisible. I'm on OSX 10.5.8 and I've tried to get this working on netbeans 6.5-6.8 to no avail. I posted this to the on the netbeans irc and mailing list but haven't heard anything back. Any help would be appreciated!

• How to design this class hierarchy?

  - by devoured elysium

  I have defined an Event class: Event and all the following classes inherit from Event: AEvent BEvent CEvent DEvent Now, with the info I gather from all these Event classes, I will make a chart. With AEvent and BEvent, I will generate points for that chart, while with CEvent and DEvent I will paint certain regions of the chart. Now, how should I signal this in my class hierarchy? Should I make AEvent and BEvent inherit from PointEvent while CEvent and DEvent inherit from RegionEvent, being that both RegionEvent and PointEvent inherit from Event? Should I add a field with an Enum to Event with 2 values, Point and Region, and each of the child classes set their value to it? Should I use some kind of pattern here? Which one? Thanks.

• How Can I Add a New Command to a Control's Event

  - by Chris

  Hi, thanks for taking a look at this question. I have been building an application (VB/WPF) following Josh Smith's example of an MVVM pattern: Click here to view My Views have Controls which trigger a Command upon an event, such as a button click and these are bound to properties in the ViewModel. My ViewModel exposes properties of type ICommand which invoke the appropriate methods. This has worked well, until now! I now want to use a Thumb Control to allow a user to move an object within a Canvas. I don't believe that the Thumb has a Command capability 'out of the box'. A Thumb raises a 'DragDelta' event when being moved. So my question is as follows: How do I extend a Control's capability to issue a Command upon an event please? I wish to issue a new Command, let's say 'onDragDelta' so that I can bind it to a property in my ViewModel just like my Buttons. Thank you very much

• How do I use SimpleRepository without the migration approach?

  - by Bill Sempf

  I am evaluating SubSonic for use in Phase 2 of a large project. This is an ASP.NET project, with 700 tables in a SQL Server database. We are planning for our domain model to consist of POCO classes to assist with an offline access requirements we have. I believe that the SimpleRepository pattern would be among my best options. Since I have a database already, however, the migration assistance doesn't help me. Are there T4 templates for SimpleRepository that I just overlooked? How do I 'turn off' migration? If I missed something in the Wiki, point me there, otherwise get me started and I'll write up a Wiki entry for y'all when we get there.

• PropertyChanged doesn't work properly

  - by Karen

  Hello, I have a Silverlight application in which I implemented MVVM pattern. In my application there is a child window on which I have ComboBox. I bound ItemsSource and SelectedItem of my combobox to a property (typeof ObservableCollection) and property of MyType appropriately. MyType is a "MODEL" derived from INotifyPropertyChanged. When my window is loaded I set values to this properties. But my combobox doesn't display selected item. I found that when I set property which is bound to selected item (in ViewModel), the PropertyChanged event is null. Can anyone help me. Thanks.
