• Is it good practice to generally make heavyweight classes non-copyable?

  - by Emile Cormier

  I have a Shape class containing potentially many vertices, and I was contemplating making copy-constructor/copy-assignment private to prevent accidental needless copying of my heavyweight class (for example, passing by value instead of by reference). To make a copy of Shape, one would have to deliberately call a "clone" or "duplicate" method. Is this good practice? I wonder why STL containers don't use this approach, as I rarely want to pass them by value.

  - by user2898598

  Hi I just noticed that if you creating a new view on jEdit, when you editing the new one, it affected the text on the original window's text as well, how could I create a New view that allow the user to duplicate data for the current shown view only and not effecting the old ones? I try to find solutions on the source code, then I find seems there are setting that related to this: http://www.jedit.org/users-guide/buffersets.html but I didn't find the selection mentioned on my setting.

• PHP Include Not Working on One Page

  - by Tara

  So, I finally got the PHP include function to work by tweaking the .htaccess file yesterday. The index shows up perfectly. But get this, I duplicate the index.html file, rename it and upload it as another page (as a template to work from) and now the PHP include function is not working on that page, even though it's exactly the same code hosted on the same server with the same .htaccess file. Any idea what's going on? Thank you, Tara

• Workaround for JFormattedTextField delete bug in Java for Mac OS X 10.6 Update 2 (1.6.0_20)

  - by Johan Kaving

  There is apparently a bug introduced in the latest Java update for Mac OS X, which causes deletes in JFormattedTextFields to be performed twice. See http://lists.apple.com/archives/java-dev/2010/May/msg00092.html The DefaultEditorKit.deletePrevCharAction is invoked twice when the delete key is pressed. Are there any suggestions for a workaround? I'm thinking of replacing the delete action for my text fields with a patched version that somehow filters out these duplicate invocations.

• Bind multiple events to jQuery 'live' method

  jQuery's 'live' method is unable to handle multiple events. Does anyone know of a good workaround to attach multiple events to a function that polls current and future elements? Or am I stuck using duplicate live methods for each event handler I need? Example - I am trying to do something like: $('.myclass').live('change keypress blur', function(){ // do stuff });

  Possible Duplicate: GOTO still considered harmful? There were times the code would have been so much shorter, but my high school CS teacher would never allow us to use goto loops.

• Is there a user provisioning API, and/or account migration/transition tool for Gmail on Google Apps?

  - by Olaseni

  I've decided to move all the mail accounts in my domain to Google Apps: Is there a subtle migration tool that can make the transition painless, since I want all the mail history and folders to be intact. I'm also looking to duplicate the user provisioning API with Google Apps Users alternative. Are my goals realistic? Are there any tools out there that already make this task simpler?

• Are GUID primary keys bad in theory, or just practice?

  - by Yarin

  Whenever I design a database I automatically start with an auto-generating GUID primary key for each of my tables (excepting look-up tables) I know I'll never lose sleep over duplicate keys, merging tables, etc. To me it just makes sense philosophically that any given record should be unique across all domains, and that that uniqueness should be represented in a consistent way from table to table. I realize it will never be the most performant option, but putting performance aside, I'd like to know if there are philosophical arguments against this practice?

• Counting words in a collection using LINQ

  - by icemanind

  Guys, I have a StringCollection object with 5 words in them. 3 of them are duplicate words. I am trying to create a LINQ query that will count how many unique words are in the collection and output them to to the console. So, for example, if my StringCollection has 'House', 'Car,'House','Dog', 'Cat', then it should output like this: House -- 2 Car -- 1 Dog -- 1 Cat -- 1 any ideas on how to create a LINQ query to do this?

  - by Jeff Miller

  For example: >>> x = [1, 1, 2, 'a', 'a', 3] >>> unique(x) [1, 2, 'a', 3] Assume list elements are hashable. Clarification: The result should keep the first duplicate in the list. For example, [1, 2, 3, 2, 3, 1] becomes [1, 2, 3].

• Modular GWT design concerns

  - by GlGuru

  Hi, I have a couple of questions regarding a modular GWT based application framework. I have some ideas about them but being new to the field of web development I feel they are far from ideal. I'd appreciate a few comments and suggestions in this regard. Here are my questions: I am developing a framework which will allow third parties to embed GWT applications into our website and do some communication with them using simple iFrame postMessage. All these third party modules are going to use our SDK which is also GWT based. The problem arises that even though all the modules will be using the same codebase there is going to be a massive overheard in the amount of duplicate Javascript code (i.e. our common SDK code base which is quite large) being downloaded on the client's machine. This is highly redundant and problematic, not only due to the sheer size of duplicate code but, also due to the fact that subsequent updates of the SDK would require the modules to be recompiled which is going to create a DLL hell kind of scenario in the long run. What is the best way of doing this kind of thing? Is there a way where I can have some static GWT code (i.e. the SDK) and the dynamic GWT module refers to it (even if lies on a different domain) and it all work happily? The other part of the problem lies in providing robust scripting front end to the SDK. At first it appears to be trivial since Javascript itself is a scripting language. However, I do not know how to load and call a piece of pure Javascript code at runtime? I am willing to put restrictions on the target Javascript (i.e. having a function main and unique namespace or something). Furthermore the Javascript will come as a string from a database and not as a full URL. If its doable in Javascript how does one get this right in GWT i.e. forcing the compiler to emit a certain function in the generated Javascript? This I believe can be lesser of a problem by having a stub Javascript with all the right requirements which just loads up a GWT generated Javascript. Is any of this possible at all? I generally hate to be this verbose but I hope to find a quick solution to the problem as its holding up my progress. I'd highly appreciate any comments, suggestions and experiences.

• Facade controller, is it efficient?

  - by Berlioz

  Using a facade controller pattern in .net. It seems as if though it is not efficient BECAUSE, for every event that happens in a domain object(Sales, Register, Schedule, Car) it has to be subscribed to by the controller(use case controller) and then the controller in turn has to duplicate that same event to make it available for the presentation, so that the presentation can show it to the user. Does this make sense? Please comment!

• Logical equality in C

  - by andrew cooke

  [It seems odd this doesn't exist, so apologies in advance if it's a duplicate] I want to test for logical equality in C. In other words, I want to know whether two values would be equal if both were converted in the normal way associated with logical expressions. In C99, I think that (bool)a == (bool)b gives what I want. Is that correct? What is the normal way of writing this in traditional C?
