• Why are there differing definitions of INT64_MIN? And why do they behave differently?

  - by abelenky

  The stdint.h header at my company reads: #define INT64_MIN -9223372036854775808LL But in some code in my project, a programmer wrote: #undef INT64_MIN #define INT64_MIN (-9223372036854775807LL -1) He then uses this definition in the code. The project compiles with no warnings/errors. When I attempted to remove his definition and use the default one, I got: error: integer constant is so large that it is unsigned The two definitions appear to be equivalent. Why does one compile fine and the other fails?

• New to CakePHP -> How To Add Columns To a MySQL Table?

  - by walden

  I had a website made for me a long time ago, and the programmer did it in CakePHP. I'm now editing his scripts. I added a couple columns to a table, and found that doing saveField() on the new column does not do anything. How do I make CakePHP recognize the new columns? I'd appreciate your help. I'm not too familiar with CakePHP, so please go easy on me =)

• C++: Is windows.h generally an efficient code library?

  - by Alerty

  I heard some people complaining about including the windows header file in a C++ application. They mentioned that it is inefficient. Is this just some urban legend or are there really some real hard facts behind it? In other words, if you believe it is efficient or inefficient please explain how this can be with facts. I am no C++ Windows programmer guru. It would really be appreciated to have detailed explanations.

  - by Dbger

  I was asked of this question when mentor an entry-level programmer, I was thinking of this compile + link process so official and usual that I never think about why.

• Is 1-to-n multicast on the open internet reliable?

  - by Jeremy Dunck

  I'm a newbie at networking. I understand the concept of multicast, but was wondering if it's reliable on the open/public internet? It seems like sort of an edge case that different backbones or ISPs might intentionally break to reduce router load or generally segment the network for practical high-use applications. Is my fear reasonable? P.S. Follow-up question here: http://stackoverflow.com/questions/256125/best-tutorial-for-application-multicasting

  I completely newbie in device drivers, so I hope my question is in place, but I need to develop a driver to control some equipment.

• CursorLoader, get URI for local database

  - by user1681358

  I'm a newbie android programmer and I recently followed a tutorial which shows how to create a local SQLite database by using SQLiteDatabase.rawQuery to return a Cursor. I would like to modify my app to use CursorLoader which is apparently a better way to access the database. My problem is the CursorLoader constructor expects a URI to be given. Do I just input "file:///[path to db]"? Seems a bit messy.
