  • Visual Studio appears to randomly adopt american keyboard layout

    - by HollyStyles
    Gah! this is really causing me hassle today. Suddenly without warning '@' (at symbol) and '"' (double quote) are trading places on my keyboard but ONLY in Visual Studio 2008 !!! I can't seem to find anything in help or online to explain/remedy this. Is there some keyboard shortcut I am inadvertantly executing?? I rebooted my PC and it went away for an hour or two and then suddenly came back. Oh the insanity :(

  • The use of Javascript - stats?

    - by Luke
    I am looking at redesigning my website and was wondering if I could get some opinions. I know that the rule is usually to design with users without JS first and foremost, but having looked at the stats, it appears 95% of the users online have JS enabled. Would you recommend designing the website using JS and not bothering about people without it?

  • In MVC framworks (such as Ruby on Rails), does usually Model spell as singular and controller and vi

    - by Jian Lin
    I usually see Ruby on Rails books using script/generate model Story name:string link:string which is a singular Story, while when it is controller script/generate controller Stories index then the Story now is Stories, which is plural. Is this a standard on Ruby on Rails? Is it true in other MVC frameworks too, like CakePHP, Symfony, Django, or TurboGears? I see that in the book Rails Space, the controller is also called User, which is the same as the model name, and it is the only exception I see. Update: also, when scaffold is done on Ruby on Rails, then automatically, the model is singular and the controller and view are both plural.

  • StringBuilder/StringBuffer vs. "+" Operator

    - by matt.seil
    I'm reading "Better, Faster, Lighter Java" (by Bruce Tate and Justin Gehtland) and am familiar with the readability requirements in agile type teams, such as what Robert Martin discusses in his clean coding books. On the team I'm on now, I've been told explicitly not to use the "+" operator because it creates extra (and unnecessary) string objects during runtime. But this article: http://www.ibm.com/developerworks/java/library/j-jtp01274.html Written back in '04 talks about how object allocation is about 10 machine instructions. (essentially free) It also talks about how the GC also helps to reduce costs in this environment. What is the actual performance tradeoffs between using "+," "StringBuilder," or "StringBuffer?" (In my case it is StringBuffer only as we are limited to Java 1.4.2.) StringBuffer to me results in ugly, less readable code, as a couple of examples in Tate's book demonstrates. And StringBuffer is thread-synchronized which seems to have its own costs that outweigh the "danger" in using the "+" operator. Thoughts/Opinions?

  • Do people create and use Web Parts connections?

    - by Javaman59
    I've been writing some SharePoint web parts wich connect (as providers and consumers). I've found many difficulties, and (comparatively*) little material from the web, from books, or from microsoft.com, which is quite surprising as Web Parts have been around since 2003. This is making me think that although web part connections look like a first class feature in SharePoint, that in practice few people write connecting web parts, and few SharePoint users use them. Is this the case - that few developers write connecting web parts, and few users use them? *comparitively: A subjective impression. With each specific problem i usually find only a handful of web pages which address it, and as my problems seem to be fundamental ones (such which data type to wrap in an IWebPartRow), I expect a lot more search results.

  • Filter across three tables using Django

    - by Vanessa MacDougal
    I have 3 django models, where the first has a foreign key to the second, and the second has a foreign key to the third. Like this: class Book(models.Model): year_published = models.IntField() author = models.ForeignKey(Author) class Author(models.Model): author_id = models.AutoField(primary_key=True) name = models.CharField(max_length=50) agent = models.ForeignKey(LitAgent) class LitAgent(models.Model): agent_id = models.AutoField(primary_key=True) name = models.CharField(max_length=50) I want to ask for all the literary agents whose authors had books published in 2006, for example. How can I do this in Django? I have looked at the documentation about filters and QuerySets, and don't see an obvious way. Thanks.

  • Deserialize array values to .NET properties using DataContractJsonSerializer

    - by James Cadd
    I'm working with the DataContractJsonSerializer in Silverlight 4 and would like to deserialize the following JSON: { "collectionname":"Books", "collectionitems": [ ["12345-67890",201, "Book One"], ["09876-54321",45, "Book Two"] ] } Into classes like the following: class BookCollection { public string collectionname { get; set; } public List<Book> collectionitems { get; set; } } class Book { public string Id { get; set; } public int NumberOfPages { get; set; } public string Title { get; set; } } What's the proper place to extend DataContractJsonSerializer to map the unnamed first array element in "collectionitems" to the Id property of the Book class, the second element to the NumberOfPages property and the final element to Title? I don't have control over the JSON generation in this instance and would like the solution to work with the Silverlight subset of .NET. It would be great if the solution could perform the reverse for serialization as well.

  • How to load another's service certificate to my WebLogic truststore?

    - by Murugan
    An online service provided me with their certificate (a pfx file) along with its password. I am looking to load that into my WebLogic 8.1 truststore in Unix. There is a truststore currently that exists in my WebLogic. I am new to this so I was wondering what was the process to add that other party's certificate to my existing WebLogic keystore. Do I need to convert the pfx file into a different for Unix?

  • Safest LAMP encrypt method

    - by Adam Kiss
    Hello, what is PHP's safest encrypt/decrypt method, in use with MySQL - to store let's say passwords? Of course, not for portal purposes. I want to do little password (domain/mysql/ftp...) storage for whole team online, but I don't want really to endanger our clients' bussinesses. Hash can't be used for obvious reasons (Doesn't really make sense to run rainbow tables every time :D). Any idea?

  • C++ library for Coordinate Transformation Matrices (CTM)?

    - by BastiBense
    I'm looking for a C++ library which allows for easy integration of Coordinate Transformation Matrices (CTM) in my application. You might know CTMs from PDF or PostScript. For one project we are using C++/Qt4 as a framework, which offers a QTransform class, which provides methods like .translate(double x, double y) or .rotate(double degrees). After doing some transformations, it would allow me to get all 6 CTM values, which I could feed into a PDF library or use a transformation matrix in export files. Qt's API also allows for arbitrary mapping of polygons (QPolygon), rectangles (QRect) and other primitive data structures into transformed coordinate systems. So basically I'm looking for something similar to what Qt provides, but without the need of using Qt. I know I could do the matrix multiplications myself, but I'm not really interested in doing so, as I'm very sure that someone already solved this problem, so please no links to books or other guides on how to multiply matrices. Thanks!

  • Dispose a Web Service Proxy class?

    - by Matt
    When you create and use a Web Service proxy class in the ASP.Net framework, the class ultimately inherits from Component, which implements IDisposable. I have never seen one example online where people dispose of a web proxy class, but was wondering if it really needs to be done. When I call only one method, I normally wrap it in a using statement, but if I have a need to call it several times throughout the page, I might end up using the same instance, and just wondered what the ramifications are of not disposing it.

  • Context aware breadcrumbs with php sessions - Will search engines index each variation?

    - by Haroldo
    Some pages on my website appear differently depending on where the user has been, using php sessions. for example with breadcrumbs: standard crumb setup: All Books - fiction - Lord Of the Flies if the visitor has just been on the 'William Golding Page', a session will have been created to say, this visitor is broswing by author, so i would check if( $_SESSION['browsing by] == 'author' ): and the breadcrumbs (for the exact same page as before) would now be: Authors - William Golding - Lord Of the Flies to summarise: So 1 page exists for each book, but depending where the user has come from, the page will show different breadcrumbs. the questions: Can search engines create my 'browsing by' SESSION? Would they index the same page multiple times (for each variation)?

  • Download data in background with iOS4

    - by Sagar
    As per the latest update of Kindle V2.5, it has support of "continue downloading books while the app is in the background on iOS 4 devices". How is it possible to download content in background? As per the iOS multitasking documentation, only audio, voip & location updates are possible in background. And I've also maken sure that NSURLConnection doesn't download new data work while app goes background. Then how's it possible with Kindle app? Edit: I haven't checked Kindle App in iOS4 multitasking enabled device. So if anyone let me (& community) know what exactly Kindle app does to download, that would be very much helpful.

    Hello, I've just discovered Sikuli, and would like to see a comprehensive functions list without digging through the online-examples and demos. Has anyone found such a list? Furthermore, apparently Sikuli supports more complex loops and function calls as well, and seems to be based in Python(!!). Examples would be great. Thanks.

  • reinitialize an object with self.__init__(...)

    - by Kara Jevo
    Could anybody explain whether it is safe to reinitialize an object by calling "self.init(". as shown in the following simplified example? The reason i'm asking is that i couldn't find this method neither in several python books nor in internet. There are some who suggest to list all attributes and set them to initial value one by one. Basically i want to set my object to initial state after it has finished some tasks. class Book(object): def __init__(self,name,author): self.name = name self.author = author self.copies = 5 def reset(self): self.__init__(self.name,self.author) def incrementCopy(self): self.copies += 1 Kite = Book('kite runner','khaled hosseini') print 'initial number of copies:', Kite.copies Kite.incrementCopy() Kite.incrementCopy() Kite.incrementCopy() print '3 copies are added:', Kite.copies Kite.reset() print 'number of copies are reinitialized', Kite.copies initial number of copies: 5 3 copies are added: 8 number of copies are reinitialized 5
