Shall we move the substantive meetings to Wednesday & have the draft reviews (if needed) on Thursday? This would aid in a scheduling conflict that has come up for Prof Kahan this year & others have mentioned it might make it easier for those who fly into these meetings to schedule their return flights. Yes.

Let us determine dates & venues for our meetings for the rest of the year. (After the meeting, Eric Postpischil of Apple arranged to host August & November.)

Prof Kahan wishes to speak to defaults & their effect on debugging issues.

http://www.cs.berkeley.edu/~wkahan/
Wants double extended or quad available for debugging & reducing the probability of round off error induced bugs into the noise. This & humane exception handling must be mandatory. And redirecting rounding direction.

Jeff's group will present the result of the rules committee. You can find their revised version at either of:

http://754r.ucbtest.org/pnp-0.8.html
http://nonabelian.com/754/PnP_0_8.htm
This is our draft of the rules given to us by the MSC as approved for IEEE committees & working groups that report to the MSC. Largely the removal of entity & meta-comments together with some small modifications. Some questions came up in 4.1 about the signing of a Copyright Assignment Form "prior to active participation and/or voting in any working group meeting." Prof Kahan suggested replacing Assignment with Release & go on. In 6, "All officers shall be..." changed to "The chair shall be...". After MUCH discussion we changed an 'after' to 'upon'.

Our PAR (754Revision) expires December 2006. Bob Davis will explain what we need to finish by then.

Must be available for the October MSC meeting & need to ask for a sponsor ballot by the July MSC.
