[jira] Commented: (MATH-157) Add support for SVD.
[ http://issues.apache.org/jira/browse/MATH-157?page=comments#action_12446796 ] Tyler Ward commented on MATH-157: - Not bad. Looks like everything is in the right place, modulo a transpose or two perhaps, but looks good. The eigenvector reduction is really the heart of this algorithm. Your QR iteration will work (I think), but it's really inefficient. The trick is to do two different reductions. The first should reduce to tridiagonal form (this can be done with only 2(N-2) matrix multiplications, rather than the 200 or so you're using), and then use the givens rotations to reduce tridiagonal to diagonal. Should take about 5N rotations, but each is only about 10N operations or so (rather than N-cubed for a regular matrix multiply).

[jira] Resolved: (CONFIGURATION-229) config : load for a configuration node is called before parsing is complete : attributes ignored
[ http://issues.apache.org/jira/browse/CONFIGURATION-229?page=all ]
Oliver Heger resolved CONFIGURATION-229.
Fix Version/s: Nightly Builds
Resolution: Fixed
A fix was committed that causes the load() method to be invoked after
initialization of all specified properties is completed. This should solve this
problem. Please double-check.
Thanks!

is there a context sensitive properties configuration class available?
Hi all, I am looking for a properties configuration class that is context sensitive, which means the value of a property depends on the context. For example, I have a website that uses different databases on dev, stage and production environments, but all use the same user name and password, so my properties file should look like this: DB_URL (DEV)=jdbc:mysql://10.0.0.1 DB_URL (STAGE)=jdbc:mysql://10.0.0.2 DB_ URL(PRO)=jdbc:mysql://10.0.0.3 DB_USER=joe_user DB_PASSWD=abc123 It may be named something differently. But can anyone tell me if there is any class like this? Thank you. Alex Zhang

[jira] Commented: (BEANUTILS-255) ConvertUtilsBean does not support converts to a java.util.Date
[ http://issues.apache.org/jira/browse/BEANUTILS-255?page=comments#action_12446722 ] Simon Kitching commented on BEANUTILS-255: -- I'm not sure this is a good idea. Presumably this converter would use the "system locale" to determine how to parse the input strings. This means that 01/02/2006 will generate 01 Feb 2006 when run on a server in Europe, and 02 Jan 2006 when run on a server in the USA.

But it can also access a list and therefor throw an IndexOutOufBoundsException, so it should be mentioned in the javadoc as well. Since ArrayIndexOutOfBoundsException is a variation of IndexOutOufBoundsException with essentially the same meaning, one could limit oneself to IndexOutOufBoundsException. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
[daemon] Re: Obtaining procrun for Win32
Hi David, This thread might be of use: http://mail-archives.apache.org/mod_mbox/jakarta-commons-user/200606.mbox/[EMAIL PROTECTED] Looking at my last year of user archives, I don't see any questions on daemon being answered and I can see lots of svn commits for it so it's still active. Ccing the commons-dev list to point this out to the daemon developers. Thanks, Hen On 11/1/06, David Sills <[EMAIL PROTECTED]> wrote: Hi there: I went to look on the commons daemon site for Procrun, and although I see a page explaining its use, I see nowhere from which to download the software. The "Native binaries" page has only versions for various UNIX flavors. Sorry if I am being dense, but I really like Apache software, and would like to consider Procrun as a Windows service provider along with some other options for adoption. Any advice would be gratefully received. Thanks!
