Re : Welcome the newest Mahouts!
Got my Apache account yesterday 8D being a coder I always find it different to write other things than code =P, so my biography will probably be weird: I am an algerian PhD student, I'm expecting to use machine learning algorithms (probably evolutionary computing) and distributed computing (mahout? maybe). During my master I worked on Artificial Immune Systems applied to pattern recognition. I like coding, mainly in Java, but also in C# (although being at pro-noob level in C#). The past two years I learned a lot with mahout's community, and I'm looking forward to learn much more. --- En date de : Mer 26.8.09, Grant Ingersoll a écrit : > De: Grant Ingersoll > Objet: Welcome the newest Mahouts! > À: mahout-u...@lucene.apache.org, "Mahout Dev List" > > Date: Mercredi 26 Août 2009, 16h57 > I am pleased to announce that the > Lucene PMC has voted to add Deneche Abdelhakim, Robin Anil > and David Hall as Mahout committers.

Updating the Web site
I followed the instructions available here: http://cwiki.apache.org/MAHOUT/howtoupdatethewebsite.html in order to add my name to the committer list =P when running 'forrest run' but I'm getting broken links: X [0] skin/images/current.gif BROKEN: /home/hakim/apache-forrest-0.8/main/webapp/.

(Is a directory) it also sais that "Your site would still be generated, but some pages would be broken." svn status shows me that I only modified "src/documentation/content/xdocs/whoweare.xml" can I proceed anyway and copy the site to the publish directory ?

Re: Updating the Web site
Hmm, make sure you have proper permissions to write on the forrest install. I believe Forrest downloads stuff to its directories. I recall seeing similar things. Very annoying.

[jira] Created: (MAHOUT-178) Rationalize 'utils' and 'common' stuff
Rationalize 'utils' and 'common' stuff -- Key: MAHOUT-178 URL: https://issues.apache.org/jira/browse/MAHOUT-178 Project: Mahout Issue Type: Improvement Affects Versions: 0.1 Reporter: Sean Owen Assignee: Sean Owen Priority: Minor Every project needs a common area for code that is not obviously part of any specific piece of the project, typically because it's used in many places. This is good as it promotes reuse. I would like to make an explicit effort to rationalize this project's approach to 'common', starting with some basic reshuffling, which will then pave the way to unify more of the code that is duplicated now (thinking: caches, distance measures, Hadoop integration, etc.) Right now we have this common code in three places, when it seems like there should be basically one: - mahout-core: org.apache.mahout.utils - mahout-core: org.apache.mahout.common - mahout-utils I suggest that of the two packages named above, 'common' is slightly preferable; one could easily just merge these packages. I also would like to ask whether it makes sense to have a mahout-utils module? It's like having a mahout-core-core, in my opinion. It appears to serve exactly the same role as the other utils/common package. Would it ever be used as a standalone build product? Renaming may sound like a trivial change, but I think the above is merely symptomatic of several developers having independent ideas about where to stash common stuff. I want to force the issue and push everyone's stuff together to begin the hard but necessary work of refactoring the code base into something more unified. So far, I propose pushing all code together into org.apache.mahout.common. This is enough of a big-bang that will break patches that I want to propose it, and if agreed, plan when to commit. (Also, shouldn't stuff like the distance measure classes be in a package?) Anyway, partial patch will be attached shortly. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.

JIRA permission ?
now that I'm a committer ( 8D ) I suppose I can assign JIRA issues to myself. Do I need a special permission to do that ? because I'm not able to find a way to do it =P
