Subject Re: [math] Name of the new TLP
Date Wed, 03 Feb 2016 15:58:19 GMT
Just my 2 cents.

When HttpClient left Commons I believe they took that opportunity to re-architect their code.
In the end I think it paid off, but for quite I while lots of folks (myself included) continued
using Commons HttpClient because the new version was regarded as immature.  They also wanted
to widen their scope a bit so they went from Apache Commons HttpClient to Apache Http Components.


I don’t contribute to or use Apache Math myself, but given my experience with HttpClient
I would say that using a name that strays very far from Math would be doing yourselves a disservice.
 It is a bit of a stretch to expect people to remember that Commons Math is now Apache Aardvark
or some other obscure name when the one you have is pretty much perfect. The only way people
will find you is via a link on the Commons home page whereas math.apache.org <http://math.apache.org/>
just makes sense & is easy to remember.
