An old member returns... - rprosperi - 02-14-2015 10:08 PM
Just noticed this in the Board Statitics area:
"Please Welcome our newest member, Valentin Albillo"
So welcome back Valentin, your absence here has been strongly noted. We hope you're back for more than a short visit.

Welcome back, Valentin!

Of course he should come back on February 14th... ;)

Welcome back from me, too!

Ah, but how do we know it is the "real" Valentin Albillo and not wob2?
If he concocts a one-line challenge, then we will know.
Welcome back old friend.

Welcome back old friend.
I wondered about this before posting, but concluded it's unlikely someone trying to not be seen/caught is unlikely to adopt such a well-known and respected persona. Let's hope not, that would be disappointing.

Hi all:
Thanks for your warm reception, I think it will be better if I reply to all of you in this one post instead of clogging the thread with multiple ones. Let's see:

Thank you very much for your kind post, Bob, I'm pretty busy as always but I intend to participate as my allocated free time allows so this won't be a short visit.

Thanks for your appreciation and warm welcome, Massimo. And yes, it's no coincidence that I chose February 14th for registering. Historically I've always been very fond of my namesake Valentine's Day and even concocted a number of quite successful "minichallenges" and such to commemorate the day.

Wow ! A 10^10 million thanks, Geir, that's quite a red-hot welcome indeed !

Thanks a lot, Thomas, your warm welcome is duly appreciated.

Such skepticism !
AFAIK, there's no other "Valentín Albillo" in the whole world but me, as the name-surname combination is quite unusual (unique, it seems).
And BTW, Don, who or what is "wob2" ?

Welcome back old friend.
How about this one:
Write a one-line program that will output the solution to this micro-challenge I've concocted right now (thus no use searching the net) for the occasion:
If 9x9=29, what's the square root of 69 ?
Your one-line program must be as short as possible (least number of characters), must do the required calculations (not simply print the answer right away) and must output the shortest possible answer, one byte is better than eight and one nibble is better than one byte.
I'll produce an HP-71B solution after interested people give it a try. Of course I know it will be solved at once but I hope this will do to dispel concerns about my identity and prove that I'm the real VA ... and speaking of the devil, if VA is square, what's the square root of me ?

Indeed. These matters will be the subject of future posts.

Hi, Ángel. Er, well, I'm here, at my usual address, as always. Nice to see you're in this new forum, too, and as busy as ever judging for your posts.

No sweat, I'm the real McCoy, as they say. And thanks again for your extremely kind words, much appreciated.
That's all, best regards to all of you.

Glad to see that you are the real McCoy! :)
Welcome back once more.
Interesting days ahead...
RE: An old member returns... - Don Shepherd - 02-20-2015 01:57 AM
Valentin, a forum member was recently banned from making posts on the forum for a few days, and a new account suddenly appeared named "wob" that, it was speculated,
might have been created by this person to get around the temporary ban.
Glad to see you back and I am looking forward to the infamous Albillo challenges.

Hello Valentín,
First of all, welcome back!
1 CHR$(SQRT((9*9-9)/2*6+9)+55) ENDLINE will produce a one-line HP-71B program which upon run will give a one-character answer. Not sure wheter this will count as a valid solution to your micro-challenge though.
Best regards,
Gerson.

I'd skipped that part, sorry!
Best regards,
Gerson.
P.S.: I've made a great mistake, one order of magnitude! – I used 1 instead of 10 thus getting 32 when I should have gotten 45. I don't have a one-nibble symbol for this though. My bad :-(

I really enjoyed all your "Long Live the HP-....." Articles. They help put me into the excitement of the times these great machines were first introduced!

Hmmh - VA equals W; I've never heard of the square root of VA equaling anything reasonable. What am I missing?

Actually VA equals W only when var equals zero [ VA = sqrt(W^2 + var^2) ]. This has nothing to do with VA's little riddle though. The square root of VA might be W for a quite different reason, if I got him right. Also, VA as we know him is a real entity, not an apparent one. :-)
P.S.: I thought you were referring to another kind of VA. Yes, your VA does equal W. Sorry!

As an electric engineer and knowing Valentin, I can only share your point :-)
In one of his famous S&SMC , Valentin asked to find a solution on the HP-71B to the equation:
Abs(Ln(x*x)-Ln(x^2)) > 4.012007 (BTW, I found a solution ...)
In the same way, is it possible to have square of VA significantly different from the product of VA by VA?
Let's take all this with humour... :-)
