Re: Jakarta namespace in commons like dbcp - thoughts / ideas?
@Gary as mentionned there are matches but also notice several vendors (most) abandonned the game due to the new governance so dont expect as much choices as before.

Re: Jakarta namespace in commons like dbcp - thoughts / ideas?
There is a Jakarta artifact available for Narayana: narayana-jta-jakarta For the SPI: jboss-transaction-spi-jakarta (because JBoss plays the namespace game with their app server ;-) ) Geronimo most likely also provides a Jakarta version or (if it is only API) can be replaced by the Jakarta artifact.

Re: Jakarta namespace in commons like dbcp - thoughts / ideas?
There is non point in doing this "quickly", if there is no match in the namespace game for the test dependencies, it only goes to prove that the whole ecosystem has not progressed far enough or is mature enough.

Re: [math] contribution proposal for multivariate functions optimization (2)
Hello, I am finally done with a draft version of multivariate optimizers (gradient descent, Newton-Raphson, BFGS) that fits the legacy API design and class hierarchy. The new code is compliant with checkstyle rule. My question is : "what's next?". I suppose that I should have access to a specific git branch so that I can submit my code as a pull request? Or is there another specific process? By the way, I have not been able to create a JIRA account. Many thanks in advance François Laferrière Le vendredi 21 octobre 2022 à 15:47:51 UTC+2, Gilles Sadowski a écrit : Hello. I haven't looked at the code, but thanks for your interest in contributing to Commons Math. The more straightforward path is indeed to adapt your code to what is currently in the "...legacy" module. However, you can really consider the other venue, i.e. a design specific to this family of optimizers to be defined in a separate module. [In the current "legacy" code we tried to share as much code as possible, but this has led to various design issues.] Which is best is certainly not clear-cut. My hope is that starting from a clean slate may help us make progress on several aspects of the library that we wanted to change anyways[1] (as per the JIRA records). Regards, Gilles [1] For example, usage of external matrix algebra implementations.

Re: Jakarta namespace in commons like dbcp - thoughts / ideas?
@Emmanuel Bourg you can use jakarta artifacts directly for dbcp or tomee ones which provides jakarta namespace.

Re: Jakarta namespace in commons like dbcp - thoughts / ideas?
I tried to replace javax with jakarta in DBCP, the less trivial part is to find a replacement for the test dependencies: - org.apache.geronimo.modules:geronimo-transaction - org.jboss.narayana.jta:narayana-jta - and maybe org.jboss:jboss-transaction-spi Or we disable the transaction tests temporarily to publish quickly a Jakarta variant.

Re: [ANNOUNCE] Commons Math 4.0-beta1
I noted the beta on maven. Should I delete the older version from the POM file? I now have both in my code; Also is it appropriate to ask a question on the LevenbergMarquardtOptimizer in this forum? If so, in the LeastSquaresOptimizer.Optimum object what is the appropriate value for the getSigmas function? I assume the function returns the standard error for each of the estimated coefficients. Have a Happy New Year!
