• RESTful web service, PUTting an unnamed resource?

  - by James L

  I have a back-end service that creates unique identifiers for resources. The general idea is that resources are saved and versioned, so you can perform: GET http://service/sales/targets/7818181919/latest or GET http://service/sales/targets/7818181919/4 for version 4, and so on. My question is about the most correct way to upload these resources in the first place. How about: PUT http://service/sales/targets/ returning 303 See other /service/sales/targets/ It seems a little wrong as you should PUT and GET from exactly the same place using a resource-oriented interface, but I can't think of a better option. Any ideas?

• Apache crashes after installing mysqli

  - by Marco P.

  System: Apache 2.2 running on Windows 2008 Server with PHP 5.2.17 VC6 Thread-Safe as a Module and MySQL 5.5.17 - all working fine. After installing mysqli using the php package, Apache won't start anymore. There is no error message in the log. What I have tried: Make sure Windows PATH points to libmysql.dll: Yes, done. Make sure extension_dir points to the right point: Yes. Other extensions load fine. Try without mysqli: Yes, Apache loads fine then. Try without mysql: Yes, does not help. Test mysql itself: Restarts server! Overwrite libmysql: Yes, does not help. It seems to me that there is some general problem with MySql, but the DB server seems to be running fine. I'm really out of ideas of things I could try, so I'm desperate for any hints or tricks.

• How to know if the argument that is passed to the function is a class, union or enum in c++?

  - by Narek

  I want to define an operator<< for all enums, to cout the value and print that it is an enum like this: code: enum AnyEnum{A,B,C}; AnyEnum enm = A; cout << enm <<endl; output: This is an enum which has a value equal to 0 I know a way of doing this with Boost library by using is_enum struct. But I don’t understand how it works. So that's why, in general, I am interested how to identify if the veriable is a class type, union type or an enum (in compile time).

• Why does OpenGL have to completely break backwards compatablity?

  - by directx

  I'm not sure if this only applies to JOGL or the entire OpenGL project in general. But there seems to be a vast difference between versions 3.x and 2.x; Code that works on one version will not work on another. It looks to me like the library designers intentionally renamed various classes, packages, and functions just to screw up the existing code. I've never seen anything like this before. The problem is I'm not sure which library to use now, and when looking at code it's not so easy to figure out whether it's supposed to run on 2.x or 3.x.

• can a program written in C be faster than one written in OCaml and translated to C?

  - by Ole Jak

  So I have some cool Image Processing algorithm. I have written it in OCaml. It performs well. I now I can compile it as C code with such command ocamlc -output-obj -o foo.c foo.ml (I have a situation where I am not alowed to use OCaml compiler to bild my programm for my arcetecture, I can use only specialy modified gcc. so I will compile that programm with sometyhing like gcc -L/usr/lib/ocaml foo.c -lcamlrun -lm -lncurses and Itll run on my archetecture.) I want to know in general case can a program written in C be faster than one written in OCaml and translated to C?

• How to filter/sort/rank object model nodes?

  - by BCS

  I have some kind of object model and I need to filter and sort it's nodes for some kind of property. What kinds of automated systems exist to generate and select properties of the object model that correlate to what I want? (I'm intentionally being abstract and non-specific) I'm thinking of a system that works kind of like spam filters or supervised classification systems in that given an example data set it identifies rules that find nodes of interest. However I'm looking for a more general system in that it shouldn't require any design time information about the object model. It should work equality well as a spam filter on e-mail, a bug finder on a code base, an interest filter in a newsgroup or bot accounts finder on a social networking site. As long as it can explore the object model via reflection and be given a set of "interesting" nodes, it should be able to find rules that will find more nodes like them.

• How do I make dynamic windows in Swing?

As the result of the user activity window should change it structure/appearance some element should disappear and some appear. How do I program such "updates"? Should I close an old window and open a new one or I can modify content of window without closing it?

• Corona SDK - Make a character pass through a platform

  - by Andy Res

  I'm building a game that has a character which should jump up on multiple platforms. The jumping functionality is done, but I would like if the character is just below a platform (static body), when I press the "jump" button, the character should pass through that platform and then sit on it. Right now it collides with the platform, and character cannot jump on it. Do you have any idea how this can be achieved? Right now the platforms are represented by rectangles with "static" body type: local platform = display.newRect( 50, 280, 150, 10 ) platform:setFillColor ( 55, 55, 55) physics.addBody ( platform, "static", {density=1.0, friction=1.0, bounce=0 }) And I was thinking if I could change, or remove the body type of platform when the character collids with it, so he can pass trough platform, but I don't know how to do this, or in general if this will work... maybe there are some built in techniques on how to achieve the effect I want?

• What are the merits of using the various VCS (Version Control Systems) that exist to track Drupal pr

  - by ZoFreX

  I'm trying to find the best version control strategy for my workflow with Drupal. I have multiple sites per install and I'm pretty sure I'll have a separate repository for each website. As far as I know, the VCSs worth considering are: SVN Bazaar (bzr) Git Mercurial (hg) I know how these compare to each other in general, but want to learn their merits/demerits for Drupal. If you're using (or have used) any of these for Drupal: What is your setup? What about the VCS you chose works well for managing Drupal projects? What doesn't?

• Drupal and Back-End Complexity

  - by Brian

  Currently I am working on a school website, and we are still in the decision-making process of choosing a framework (we know that we're not using Joomla! or hand-coding). Drupal came up as a viable choice, and currently, that is my best bet for the site. However, I have an issue with CMS's in general. I would like to develop a quite complicated and specifically custom-suited back-end application for teachers to interact with individual students, including the design of shared/custom calendars, announcement privileges, etc. I currently have a bit of expertise with HTML, CSS, PHP, MySQL, and I could wrap my head around some JavaScript and AJAX stuff if need-be. However, would such a complicated application work with Drupal (in that I could create it to specifically suite my purposes)?

• Imposing email limits on web page

  - by Martin

  To avoid spammers, what's a good strategy for imposing limits on users when sending email from our site? A count limit per day on individual IPs? Sender emails? Domains? In general terms, but recommended figures will also be helpful. Our users can send emails through our web page. They can register and log in but are also allowed to do this without logging in, but with a captcha and with a field for the senders email. Certainly, there is a header, "The user has sent you the following message.", limiting the use for spammers, so perhaps it's not a big problem. Any comments on what I'm doing will be greatly appreciated.

• How to show a window that acts like a popup menu?

  - by Edwin

  Hi, When window A is show, I want to show another none-modal popup window B, but: I don't want window A to become inactive due to window B becomes the front window; I want that when window B is focused, I pull down a combo box control on window A with one click (generally you have to click twice, one for moving the focus to window A and the second for pulling down the combo box); As you can see, the window B that I want is something like a more usable popup window like a popup menu (which is less a obstacle than a general none-modal window when you want it to get away by clicking on any other part of the parent window). Am I clear on my question? Thank you.

• Does this pattern have a name?

  - by LK7jb

  Disclaimer: I'm trying to learn proper OO programming/design, so I'm pretty new to this stuff. I guess this is a general design patterns question, but I'll base my example on a game engine or something that renders objects to the display. Consider the following: How can this sort of separation between physical objects (e.g., cubes, spheres, etc.) and the rendering mechanism be achieved in an extensible manner? This design is not set in stone, and perhaps I've got something wrong from the start. I'm just curious as to how a problem like this is solved in real world code.

• Is it possible to exclude folders from a web application project in vs 2010?

  - by JL

  I had previously asked this question. At the time I was working with VS 2008. To restate the question. I have a web application that generates 1000's of small xml files in a certain directory. I would like to exclude this directory from the web application project in visual studio 2010. With vs 2008 it was not possible. Has anything changed? Besides the general wait for VS to iterate through this directory and add an item in the solution explorer for each file, it also strains my system resources, so I would like to exclude it from the project, but the dir and files need to physically exist on disk, because they are part of the application. Any OOB VS 2010 solutions, or any good workarounds? Thanks Update: This also sums up the issue nicely http://forums.asp.net/t/1179077.aspx

• iPhone SDK: How to add multiple labels to table cell?

  - by iPhone Developer

  I am trying to create a custom table cell that conveys these data fields. a.) Name b.) Address1 c.) Address2 d.) Phone In the table cell these fields should appear centered one after another. Another requirement is that each of those fields be a different font and color. For that reason, I was thinking of creating labels and attaching them to the cell but I haven't had much luck getting this working. My question is, can this be done? If so, what is the general approach to follow? Any pointers or links to examples greatly appreciated.

• Perl regular expression question

  - by user368311

  Suppose I have variables $x1 = 'XX a b XX c d XX'; $x2 = 'XX a b XX c d XX e f XX'; I want a regular expression that will find each instance of letters between XX. I'm looking for a general solution, because I don't know how many XX's there are. I tried using /XX(.*?)XX/g but this only matches "a b" for x1 and "a b", "e f" for x2 because once the first match is found, the engine has already read the second "XX". Thanks for any help.

• Is this a valid C statement ?

  - by Philando Gullible

  Lets say I write char c[99] = {'Stack Overflow'}; in C or C++ it does compiles fine but does this valid? By valid I meant not invoking any kind of undefined or unspecified behavior. Again if I write char c[99] = 'Stack Overflow'; gcc complains about multicharacter constant which is obvious but in the above when I am enclosing within curly brackets compiler is happy! why is it so ? I also notice that puts(c); after the first statement will output 'w' precisely the last character of a general string in-place of Stack Overflow. why so ? Could somebody explain this behavior may be separately.

• web service data type (contract)

  - by cyberguest

  hi, i have a general design question. we have a fairly big data model that represents an clinical object, the object itself has 200+ child attributes in the hierarchy. and we have a SetObject operation, and a GetObject operation. my question is, best practice wise, would it make sense to use that single data model in both operations or different data model for each? Because the Get operation will return much more details than what's needed for Set. an example of what i mean: the data model has say ProviderId, and ProviderName attributes, in the Get operation, both the ProviderId, and ProviderName would need to be returned. However, in the Set operation, only the ProviderId is needed, and ProviderName is ignored by the service since system has that information already. In this case, if the Get and Set operations use the same data model, the ProviderName is exposed even for Set operation, does that confuse the consuming developer?

• How do I create a certain control using Windows Forms in Visual C++?

  - by Dalze

  I am new to using Windows Forms in C++ (and just in general), and I am not exactly sure of the name or if it's even possible to do. Currently I am currently working on a school project in which we must make a program for an imaginary bookstore. I am trying right now to make a sort of list that shows what the "customer" is buying. I have to make it sort by price and ISBN and any other variable that the book has. In essence I am trying to make something like the following: I just need to know how to get started. I can't figure out what the name of the control is or how to even get it to sort every time the user clicks on the header.

• Define pointcut to capture an interface but not parent or sub interfaces

  - by mR_fr0g

  I was wondering how to define a pointcut in aspecJ the captures any method of an interface but not the methods of any parent or sub interface. pubic interface A { void methodA(); } pubic interface B extends A { void methodB(); } pubic interface C extends B { void methodC(); } I would like a poincut that only catches methodB() and not methodA() or methodC(). Is there any way i can do this in a general way without listing all the sub and super interfaces in the pointcut?

• Having access to a private variable from other classes in Java

  - by Crystal

  If I want to create a form that adds people to a List, how do I have access to that List from another class? Where would I define that List so other classes can access the members, the size, etc? For example, if I have Class Foo that has the GUI for my form, along with buttons to add and remove people to the List, it would make sense to me to declare the List as a private instance variable of Class Foo. But then if I have another class, Class Bar, how does it get the values that are currently in that List to update some other graphical components? Or is that the wrong place to declare the List in general? Thanks.

• Looking for a VIM Book

  - by sixtyfootersdude

  I have been using vim for about six months now. I know my way around pretty well. I know all of the "basic commands", have defined my own functions and have defined some syntax files. I was hopping to pickup a book on vim to read in my spare time. There is nothing specific that I want to learn I just want to improve my general knowledge. I looked on amazon and there are about 7 possibilities. Any recommendations?
