Sure. That sounds good. It would be nice if you could provide some unit tests 
as well so developers improving your code can be sure they did not break 
anything.

[jira] Commented: (MAHOUT-47) Point class is now redundant and should be removed

[Jeff Eastman (JIRA)]

 ] 

Jeff Eastman commented on MAHOUT-47:


r650209 added asFormatString() to Vector and Matrix types and their 
implementations which were factored from asWritableComparable(). Obtaining a 
String result is more useful than a WritableComparable when serializing the 
various cluster classes, and to similar clients in general.

Google Summer of Code

[Robin Anil]

Hi Everyone,
  This is one of those days where I wake up and see that I
have got accepted to GSoc with Mahout (:32-all-out:) . I am really excited
to kick start the work. I know I have a lot to understand in terms of coding
practices, the whole workflow/process. And i would like to congratulate and
say hi to my fellow Gsoc'ers Farid, Yun and Abdel,  Hi to my mentor Ian
Holsman and to rest of the community.

I am usually online of google talk: if you use it do add me:
[EMAIL PROTECTED]

Cheers and Good Day
Robin

Hi Robin, 

I am very happy that I've been accepted, thanks to the Mahout Community that 
kindly commented on my draft.

So we are four students, that's cool. I wish us good work and great fun in this 
summer.

Hakim

I am really happy, we received a few slots more than expected.  Welcome to the 
Mahout project to both of you and congratulations to the successful GSoC 
application. I wish you a lot of fun, working on your proposed topics and 
hope that all students can finish their work successfully. I think not only 
your individual mentors will help you, but as usual in Apache land the whole 
community will be happy to work with you on the mailing list.

There were quite a few applications that unfortunately were not accepted. I 
would like to invite those who did not get selected to stick around and 
contribute. As Mahout is still young, it is especially easy to make a 
difference. So if you are interested in machine learning, we would be happy 
to welcome you here, even if Google does not sponsor your summer.
