• [Embedded Python] Invoking a method on an object

  - by jmucchiello

  Given a PyObject* pointing to a python object, how do I invoke one of the object methods? The documentation never gives an example of this: PyObject* obj = .... PyObject* args = Py_BuildValue("(s)", "An arg"); PyObject* method = PyWHATGOESHERE(obj, "foo"); PyObject* ret = PyWHATGOESHERE(obj, method, args); if (!ret) { // check error... } This would be the equivalent of >>> ret = obj.foo("An arg")

• HTML 5 Video Error Media Src Not Supported

  - by Nirmal

  So I was working on a toy website (http://nirmalpatel.com/yeah/index.html). If you check the source, you can see that I have linked a m4v and ogg version. When I load this page from my own computer using a url that starts with file:// the page works fine in Safari, Chrome and Firefox. However, after I upload all of the videos and the HTML to my server Firefox stops working. I don't think it's a permissions issue as both videos have the same permission.

• What does the length attribute do when set on the @Column JPA annontation?

  - by James McMahon

  What exactly does setting the length on a column do in JPA? @Column(name = "middle_name", nullable = false, length = 32) public String getMiddleName() { return this.middleName; } I understand that you can use the annotations to generate the database schema based on the entity objects, but does length do any sort of check or truncation when persistence happens, or it solely used for schema creation? I also realize that JPA can sit on top of various implementations, the implementation I am concerned with in this case, is Hibernate.

• Drupal, ImageCache module not scaling properly

  - by Patrick

  hi, I've set on imagecache a fixed scale for my images (230 x 150). Upscaling option is unchecked. Successively, I've uploaded new images (original size 230 x 150) but for some reason they are resized: 80 x 52 Instead, if I check the "Allow upscaling" option, the size is correct, but the quality is very bad. So basically, it behaves like if my images are very small, but my original images have the correct size. thanks

• Make sure bad patterns don't come back after refactoring

  - by Let_Me_Be

  I'm refactoring an old C code. The code has absolutely no layered architecture (everything is being accessed by everything) and I'm trying to change that. I would like to cut direct access to structure members (at least write for now) and only allow access through access functions. Is there some tool (or perhaps directly the compiler) that could check this rule for me? I need this since I'm maintaining a fork and the upstream isn't very concerned with code quality.
