Posted on August 23, 2011 by jesse

When Jetty 7.5.0 is released we will have officially started to dabble in the area of distributed session handling and storage.

Posted on January 30, 2010 by gregw

There is a jurisdictional issue brewing over the future of internet standards – I know because I’m stirring the pot.  The dispute is between the WHATWG and the IETF regarding the specification process for the websocket protocol (which I have some concerns about, but none the less is supported by Jetty). The IETF is the body that has been responsible … Continue reading →

Urbanization in the noosphere – Intalio acquires Webtide

Posted on September 2, 2009 by gregw

In his Homesteading in the Noosphere essay, Eric S. Raymond likened the creation of open source projects to homesteading on a frontier, via a process of  “mixing one’s labor with the unowned land, fencing it, and defending one’s title”,  in contrast to the lawful transfer of title that occurs in settled areas.  While the lands of the web servers still … Continue reading →
