  • Problem connecting to remote mysql database

    - by user361024
    I am trying to connect to a mysql db on a shared server. I am using a java application to make the connection. Problem doesn't happen when I connect to localhost db. URL = "jdbc:mysql://SHARED HOST IP:3306/DBNAME"; USER = "dbUSER"; PASS = "dbPASS"; Connection conn = DriverManager.getConnection(URL, USER, PASS); java.sql.SQLException: Access denied for user 'DBUSER'@'mycomputersIP???' (using password: YES) It is strange that it says denied for dbuser@ mycomputersip instead of dbuser@sharedhostIP Is there a setting on my wireless router that is screwing things up?

  • One Database Field to Hold Survey Answer

    - by yar
    Skipping the question of whether this is bad design (and the question of why I would want/need to do this), I'm just wondering if my 'math' is right... I have n things that need to be put in order (n is always less than 5): thing1 thing2 thing3 ... and I'd like to store these results in a single integer for thing. My initial thought is that (obviously the code will not look like this): thing = thing1 * 1 + thing2 * 2 + thing3 * 4 + thing5 * 8 will always give me a unique value, and that any value for thing will always translate back to its values for thing1...thingn. Is this correct?

  • Any GUI libaray for iPhone & Andriod based on OpenGL ES?

    - by Jeff
    Since both iPhone and Android support OpenGL ES, is there any open source or commercial GUI library we can use for these two platforms? Or is it doable (or how difficult) to port an application from one to another platform? As I know, for iPhone only, libNUI (http://www.libnui.net) is a good choice (dynamic layout & mature), but it only provides GPL & commercial license. Any other open source tool similar with libNUI?

  • How do I mirror a MySQL database?

    - by user366133
    I'm running two load balanced servers for one website, and I'd like the databases to be synchronized. Queries may be run on either of the two servers because they are both production sites, so the replication can't just work one way. It doesn't have to be in real-time, just fairly accurate so people don't notice a difference when they get switched to a different server.

  • password limitations in SQL Server and MySql

    - by asteroid
    Does MySql 5.1 and SQL Server 2008 (Web edition, Standard) have any functional password limitations other than length limits? Are metacharacters in any form a bad idea to use, like bang, pipe, hash, any slash, carrot, and so on? I know that MySql 5.1 has a password length limitation of 16 characters that is hardcoded, but I was wondering, are any metacharacters (i.e. non alphanumerics) a bad idea to use? And is this true in SQL Server 2008 Web edition, Standard? So specifically: can symbols like: /`~:}{[]^ be used successfully? I would hope it doesn't matter to the database, but I don't understand enough about password storage in enterprise database systems yet to know for sure, and I was looking for confirmation or an explanation.

  • programming/selling mobile apps internationally

    - by dootcher
    If I'm looking to sell my app in other markets other than the U.S. on both Android and iOS, do I need to do anything inside the app coding-wise? I don't imagine that I need to but I just want to make sure. Also, while I'm at it, how do I collect on international app purchases considering they are in another currency? Will the currency be automatically converted to U.S. dollars or is that my job? Any insight on either of these questions would be greatly appreciated.

  • Why would you use the ternary operator without assigning a value for the "true" condition?

    - by RickNotFred
    In the Android open-source qemu code I ran across this line of code: machine->max_cpus = machine->max_cpus ?: 1; /* Default to UP */ It this just a confusing way of saying: if (machine->max_cpus) { ; //do nothing } else { machine->max_cpus = 1; } If so, wouldn't it be clearer as: if (machine->max_cpus == 0) machine->max_cpus = 1; Interestingly, this compiles and works fine with gcc, but doesn't compile on http://www.comeaucomputing.com/tryitout/ .

  • What work has been done on cross-platform mobile development?

    - by Nicholas
    Have any well-documented or open source projects targeted iPhone, Blackberry, and Android? Are there other platforms which are better-suited to such an endeavor? Note that I am particularly asking about client-side software, not web apps, though any information about the difficulties of using web apps across multiple mobile platforms is also interesting.
