  • Good Hash Function for Strings

    - by Leif Andersen
    I'm trying to think up a good hash function for strings. And I was thinking it might be a good idea to sum up the unicode values for the first five characters in the string (assuming it has five, otherwise stop where it ends). Would that be a good idea, or is it a bad one? I am doing this in Java, but I wouldn't imagine that would make much of a difference.

  • Is there a way to specify a default property value in Spring XML?

    - by Rog
    We are using a PropertyPlaceholderConfigurer to use java properties in our Spring configuration (details here) eg: <foo name="port"> <value>${my.server.port}</value> </foo> We would like to add an additional property, but have a distributed system where existing instances could all use a default value. Is there a way to avoid updating all of our properties files, by indicating a default value in the Spring config for when there isn't an overriding property value defined?

  • How to get the project version description in Jira via the Soap api

    - by Benju
    Does anybody know how to get the version description field for a Jira project? Using the ProjectService.getVersions method we can get an Array of RemoteVersion objects but these RemoteVersion objects do not contain the description field. http://docs.atlassian.com/rpc-jira-plugin/latest/com/atlassian/jira/rpc/soap/service/ProjectService.html#getVersions(com.opensymphony.user.User, java.lang.String) Will I have to expose my own web web service via a Jira plugin to get this?

  • When is it appropriate to use error codes?

    - by Jim Hurne
    In languages that support exception objects (Java, C#), when is it appropriate to use error codes? Is the use of error codes ever appropriate in typical enterprise applications? Many well-known software systems employ error codes (and a corresponding error code reference). Some examples include operating systems (Windows), databases (Oracle, DB2), and middle-ware products (WebLogic, WebSphere). What benefits do error codes provide? What are the disadvantages to using error codes?

  • Which third party tools/library are available for NoSQL databases?

    - by Horcrux7
    I know that NoSQL databases are very new. I am also new in this point. But exist already tools/libraries to make the life easer like for SQL databases? I think on tools for managing, maintaining, viewing or reporting of the data. There can also be libraries for easer working with the database or an abstract database layer to change the database later. I would prefer Java libraries but also other are interesting.
