• Accessing Subversion commit data externally

  - by gaoshan88

  I have need to access subversion data (commit messages, files updated, revision numbers, dates modified, author, etc.) externally. Is this something for some sort of subversion hook or is there a decent third party package for this or some other "best practice" way to approach accessing subversion data externally (and by external I mean from a php/ruby or python script... external to subversion itself)?

• How can I call a GWT RPC method on a server from a non GWT (but Java) gapplication?

  - by hansi

  I have a regular Java application and want to access an GWT RPC endpoint. Any idea how to make this happen? My GWT application is on a GAE/J and I could use REST for example but I already have the GWT RPC endpoints and don't want to build another façade. Yes, I have seen http://stackoverflow.com/questions/1330318/invoke-a-gwt-rpc-service-from-java-directly, but this discussion goes into a different direction.

• Codeignitor index.php breaking image paths

  - by BeatAlex

  When I don't edit my .htaccess file, my image path reads something like: http://this.website.com/codeigniter/inc/images/logo.jpg. However, as soon as I add this code into the .htaccess file: RewriteEngine On RewriteCond $1 !^(index\.php) RewriteRule ^(.+)$ index.php?$1 [L] (to remove the index.php from the URL), I get 404 error, even with the exact same path. How do I remove index.php and still have access to my images?

  Hello! I have this rule written in my .htaccess RewriteRule ^blog/([0-9]+)/? /obdelaj.php?ime=$1 which works but it redirects me to example.com/obdelaj.php?ime=# and i want the user to stay on example.com/blog/# I have a hostgator account and i dont have access to the httpd file , and i presume that a some configuration in httpd file is causing this, because on my localhost machine this work just fine.

• Is a display list best for this? (OpenGL)

  - by user146780

  I'm rendering 2D polygons with the GLUTesselator the first time, then they are stored in a display list for subsequent use. I think VBO's might be faster, but since I can't access the stuff that the tesselator outputs, and since it uses mixes of gl_triangle, quad, strip etc, i'm not sure how I could do this, even though I would like to use VBO's once the GLUTesselator is done with them for optimal performance. Thanks

• DeleteSubKey UnauthorizedAccessException

  - by Adam Haile

  I'm trying to write a quick app to modify some registry keys. When I'm browsing via RegEdit, I can modify and delete the keys with no problems. But when I try to use RegistryKey.DeleteSubKey() it throws an UnauthorizedAccessException Is there anyway to gain the privileges to do this? Also, why would there be a problem if my user account obviously has access to make the changes?

• How to get a random item from the tree given a parent node?

  - by Bryan

  I have a scenario where I would like to randomize the display of some items. Given a Parent item, how can I randomly select one of its child items? Of course I could load ALL the children and apply some random index or whatnot... but that would be wildly inefficient. I'm wondering if this is also inefficient: Parent.Children[random(Parent.Children.Count)]? At what point do the items get loaded when you access Parent.Children?

• Determining if Memory Pointer is Valid - C++

  - by Jim Fell

  It has been my observation that if free( ptr ) is called where ptr is not a valid pointer to system-allocated memory, an access violation occurs. Let's say that I call free like this: LPVOID ptr = (LPVOID)0x12345678; free( ptr ); This will most definitely cause an access violation. Is there a way to test that the memory location pointed to by ptr is valid system-allocated memory? It seems to me that the the memory management part of the Windows OS kernel must know what memory has been allocated and what memory remains for allocation. Otherwise, how could it know if enough memory remains to satisfy a given request? (rhetorical) That said, it seems reasonable to conclude that there must be a function (or set of functions) that would allow a user to determine if a pointer is valid system-allocated memory. Perhaps Microsoft has not made these functions public. If Microsoft has not provided such an API, I can only presume that it was for an intentional and specific reason. Would providing such a hook into the system prose a significant threat to system security? Situation Report Although knowing whether a memory pointer is valid could be useful in many scenarios, this is my particular situation: I am writing a driver for a new piece of hardware that is to replace an existing piece of hardware that connects to the PC via USB. My mandate is to write the new driver such that calls to the existing API for the current driver will continue to work in the PC applications in which it is used. Thus the only required changes to existing applications is to load the appropriate driver DLL(s) at startup. The problem here is that the existing driver uses a callback to send received serial messages to the application; a pointer to allocated memory containing the message is passed from the driver to the application via the callback. It is then the responsibility of the application to call another driver API to free the memory by passing back the same pointer from the application to the driver. In this scenario the second API has no way to determine if the application has actually passed back a pointer to valid memory.

I referenced Nunit, and changed the Namespace to the same namespace used in the main project. I can't seem to figure out how to get access to all the classes, files, etc in the main project.

• Explicitly accessing banked registers on ARM

• How do I change the default "www.example.com" domain for testing in rails?

  - by Denis Hennessy

  I have a rails application which acts differently depending on what domain it's accessed at (for example www.myapp.com will invoke differently to user.myapp.com). In production use this all works fine but my test code always sees a hostname of "www.example.com". Is there a clean way of having a test specify the hostname it's pretending to access?

• DOM Storage and locks

  - by user535759

  Since DOM storage and its equivalencies persist in between tabs and windows, I've thought about using it for message passing. The problem is that fetch and store are different operations, and therefore not atomic. I have models that rely on UUID generation, conflict resolutions, and beaconing to do the small subset of what I need to do, but my real question is this: Since the local storage is a shared memory resource, what are the locking mechanisms available for mutual access?
