HHC
Another great HHC goes into the books. Great Speakers, great demos, great stories, great times cleaning parts with alcohol and great door prizes too. I'm enjoying my 1980 HP Digest and will read my 1991 HP Journal next. It's truly surprising the breadth of knowledge one finds at these meetings - but maybe not surprising. These are RPN users after all.

My first one! I enjoyed it a lot--both meeting interesting folks and hearing interesting talks! Thanks to RIchard, et al for doing a great job!

Dave Ramsey is to be congratulated for all his hard work to get our Reno hotel facilitators organized to the point that things went really smoothly. Also, thanks to Dave for hosting a dinner at his home for the early arrivers last Thursday.

RE: HHC
That was a great conference. Geoff Quickfall showed how to repair a 41 card reader. Joe Horn showed a pattern in hailstone numbers. He was so excited he was about to burst.

Namir gave several talks on interesting algorithms for solving equations numerically.

Richard Schwartz showed a really easy way to bind books and passed around some examples, including a 3" thick Prime Manual. I can't wait to give the binding process a try.

Eric Rechlin talked about his website hpcalc.org. It was interesting to see how the number of submitted programs has changed over the years.

Tim and Cyrille answered questions with Cyrille joining us via conference link from France.

HP often hands out samples of upcoming hardware under non-disclosure agreements. Tim gave everyone a shiny new HP-41CZ Limited Edition. It's brilliant how they integrated USB and high-res color display. The ARM processor and 128MB of flash memory mean there's room for every program ever written and even the beta versions of the printed manuals look AMAZING....

Okay, I'm joking about that. But it is true that part of the conference is always under a non-disclosure agreement and sometimes participants get an early look at upcoming hardware.

The door prizes were really good. Premium prizes included two Primes, two 71B's, and 15C+ (that was the beta version of the 15C-LE), a 41CV in the box with manuals, etc. etc. The door prizes are always a treat.

This year's programming contest featured the same problem that could be solved in RPL, RPN or PPL (Prime Programming Language). I always like trying to solve the problem, but to me the real fun is the days following the conference when people on this board collectively come up with solutions far better than any entry in the contest. It's a great way to learn about programming.

That's only a sample of what was at the conference this year. If you've never been to one, you should really think about attending.

Was this posted here? I don't remember seeing it but haven't been digging deeply into the forums for the past while.

I will post the challenge unless someone beats me to it.

The hp41Cz alluded to above was a joke by Dave. Bad boy Dave!

RE: HHC
David Ramsey exhibited a few of his desktop models: the 9100, 9810 and 9820 and showed how they are made inside: UN-BE-LIE-VA-BLE !

Especially the 9100: how can a machine made with discrete transistors and diodes be a programmable RPN machine? And fast on top of that: we ran a primality program on his 9100 and on the HP-15C LE. The latter was just 3 times faster... after 40 years of Moore's law!

Fun meeting, Great people... hope you (whoever reads this post) can make it next year

RE: HHC
What a wonderful experience. I would like to express my excitement about HHC conference that was this last weekend. It was great to meet the members and hear about the latest HP industry developments.
As a newcomer everyone present made me feel welcome, what a great group! I would like to express just how much I liked the presentations. Which made many of the points so much clearer to me. The conference materials and exchange table was awesome I now have a 48g, 35s and now I can explore and create programs on my new “Toys”.

RE: HHC
Indeed.
But it is far away for me to travel to USA to attend HHC. Maybe one of these years...

Eric Rechlin has just published some HHC contents on youtube here.

Thank you!

Agree 100%! We had fun and talked all day from the break of dawn to the point where we had to drag ourselves to bed. It is one my favorite weekends of the year.

Can we get a caption for the photo? I know some of the faces, but it's nice to know all of them. I like to associate the forum posts with the person's face.

Thanks, Dave

Funny thing about that performance test: I snarked to Tim that it had taken HP 45 years to triple the performance of a calculator. The specific problem was determining whether a date-- 20140331-- is a prime number (this one is).

I keep a prime factorization program on the 9100 which is always there because, you know, CORE MEMORY. It took 59 seconds or so to figure that the only factors were 20140331 and 1, so it's prime. It took the 15CLE about 20 seconds.

Tim sniffed and timed the prime routine built into the HP Prime: 0.096 seconds. So it would be more accurate to say that HP has made a hand held calc that's 614 times faster than a desktop calc.
