Hello all and a special thanks to the attendees that sat through my 10 pm presentation.
The first day (Thursday) involved driving with Wlodek from Los Angeles to Guy Ball's house to see his collection and discuss book publishing. Wlodek also had to pick up copies of his book which has been revised to include the 12 Anniversary and 15C LE which were available to the attendees.
Guy is one interesting guy! Unfortunately we were three weeks to late to see the collection as it was sold in its entirety!
Then on to San Diego arriving at midnight thirty!
Friday stuffing proceedings envelopes with Günter Schink. Günter introduced me to "Weizen" beer during our stuffing break. Later in the evening there was more beer call as others arrived.
Hello Namir, Gene, Richard, Wlodek, Joe and his brother Jim and, well check out the list at:
As for Saturday, excluding NDA topics, the WP34S with both Niel and Marcus stole the show. Then Erics demo and discussion on the overlay. Now for me, the more complex and CLUTTERED the keyboard the more I like it. The WP34S is a work of art and for me, the clutter discourages any one from borrowing it in the cockpit.
Andreas Möller talk HP 49G+ / 50G - O.S. Extension Pack is simply amazing. What Andreas has single handedly created with help menus and language modules on the 49G... is incredible.
For everyone out there, Joe Horns presentations are as informative as they are entertaining. No wonder he won the best speaker award, and no, it was not because he tallied the votes ;-)
Patrice again wowed us with his prowess in programming with his talk on "HP-15C Benchmark: The Devil is in the Details".
Eric Smiths DIY was simply amazing. I got to hold it and was allowed to turn it on. Of course being a 41C I felt right at home but was totally blown away by the LCD display. It looked so sharp you would have thought it was printed on a clear vinyl overlay and applied to the LCD panel!
Richard entertained us with his time keeping abilities and the discussion on the PPC ROM which turns out to relevant after 30 years. Appearing in the CL ROM library and the matrix routines form the base of the WP34S matrix solutions.
Jake Schwartz filled us in on the matrix/PPC ROM aspect of the WP34S mentioned above!
Yes DAVE, you are one lucky guy, and I don't mean your TI! HOWEVER the TI is fantastic, what a display to cart around from Reno! Yes bring the others, I may bring the 9825A with the chicklet keys if I can. By the way, I am looking into those glasses, who cares if you look like a muggle (Potter).
Wlodek and Dennis harms discussed the 12C and Wlodek brought and displayed his multiple variations of the 12C since its inception.
As far as the HP crew goes, Cyrille and Tim, many many thanks and I did not think I would learn so much MORE about trees, especially since my background is Botany/Forestry! Who knew.
There were more talkers but I have to refer to my notes which are still packed. Download some photos and etc.
Here is a youtube video I just uploaded. It was part of my talk and is relevant to a thread below about benchmarks and speeds vis a vis the 41CL.
Short explanation of what you are seeing:
There is a requirement to convert metric altitudes in various countries to foot altitudes for use in the cockpit. The standard slope has been arbitrarily altered to maintain aircraft separation at altitude. The two slopes can be regressed with a test as to which slope the metric altitude input belongs. Also a subroutine to round correctly so that three significant digits are used.
13,100 meters should convert to 43,000 feet. You can see simply multiplying by the conversion "1 meter = 3.2808399 feet" does not give the correct result. An alternative approach as a thinking exercise is to create a data base where the metric is paired with the feet measure. Search for the metric and display the associated feet.
Yes I know it is cumbersome but this is just for demo purposes and it works perfectly in the CL due to its speed.
CL to CX speed comparison on data base search in extended memory.
