The Rogue HP-12c

Unfortunately I cannot read the Bloomberg article (no account).

I knew about Mike Lynch's demise from his "yacht" sinking. I didn't know (or forgot) that HP was trying to get US$4 billion from him (or his now estate).

That's a boatload (pun intended) of calculators! Even Brazillian ones at the bottom of the ocean

PS: Did Lynch use a "Rogue HP-12C" while at Autonomy? Does that explain the "over-valuation" HP is mad about?

This thing goes deeper than we ever imagined.

Thought I would do a little video to demonstrate a few things:

1. The comma bug
2. IRR example error
3. Digit precision
4. Divide by zero issue
5. A few TVM differences
   

See here.

A couple of things I haven't done:
- I can't compare on video to an HP-12c. Maybe in retrospect I should have explained what you would have got on the HP-12c, but it is pretty similar behaviour to the HP-12c platinum but returns 10 digits rather than a maximum of 12. I also didn't show you the full 16 digit precision (just 15).

I couple of thoughts - some effort has clearly gone into making this device match an HP-12c - the way the stack lifts for example, and returning only an integer N.

I watched it. Not sure that counts (except for Ewetoob hits).

Comma bug ==> no "user error". Real.

And we now know your real name. And have heard your Brit accent

I keep my online identity deliberately secret. Decades ago I used my real first name and location on a forum site. Another user tracked down a photo of me (and someone else) that I'd taken with my camera (self-timer). Uploaded to the internet without my knowledge/consent. Not to any social-media site either. A small rarely viewed one.

PS: GCHQ/NSA/etc already know enough about me.

PPS: I created this online pseudonym about 25 years ago. I'm not really "annoyed" but had already created it.

My commiserations for sitting through it! I notice it's on 3 views, so that's you, me and one other (..looking around...).

I am glad you have mellowed over years. Yes, the gap between by real name and pseudonym has been breached many times already.

None needed. Now I've seen your 12CP as well.

My main browser is very much "secured". Youtube (i.e. Google) recently changed something so now I often have use another (not as secured) one to watch videos. Google still can't learn much about me though.

For better or worse I know how such things can be used against you.
