A *Weird* American Internet Forum Registration

[Ross365]

There's a ham radio forum i want to join in the USA. It has spambot protection on the registration page. To prove you are human you must answer this riddle ;

"On a writer's desk is telephone fountain pen Windows 10 cat ham sandwich paper not fish dictionary rose candy. What will be dinner?:"


This is quite true and I have no idea what the answer is. Who's smart?

 

[Pete.]

Gonna have to be either a ham sandwich, fish or candy.

Ham forum - I'm guessing ham sandwich

 

[Kram]

Cat eats the sandwich, anyway that at best is a lunch snack and a long way from being a proper dinner.
I would close the page and go make some food..

+1. The cat's going to eat the fish anyway!

 

[Ross365]

Well, the fat cigar goes to Pete; the answer is ham sandwich. It's not a riddle, just a list of things and only one is edible .

Are there any more hoops that the forum requires you to jump through? Like a password as long as a bus, facial recognition, or whatever?

They probably want your QTH before allowing a QSO and calling QRZ......... 73

Apart from the quirky spambot question everything else was normal. I asked a question about a receiver made in the US (the Hammarlund range) but have not had one reply; bit disappointing.

What frequencies do you play on ?

Stu

 

[Ross365]

If by play you mean transmit, I'm licenced but haven't been on the air for 20 years? These days I just play around with various bits of ham radio equipment. I was licenced a very long time ago, when 2m AM was absolutely buzzing in just about every part of the UK, whereas it's pretty dead in most parts now. I sometimes think about building an AM rig for 160, 80 or 60m, but never get around to it. Ham radio is just my winter hobby for when it's too cold to go playing cars!

Can't claim this is from a site I visited - it's from a maths quiz forum

...and of course...

What, you've never eaten a pussy ?

 

[pedrobedro]

What, you've never eaten a pussy ?

Not the whole thing

 

[not done it yet]

Now, what sort of radio forum was this? Oh, ‘ham‘ is a bit topical, then!

 

[Dr.Al]

Seems a bit overkill to me for spam prevention. I was getting a lot of spam (despite recaptcha) on the contact form on my website so I added a spambot question. The question is "please write the 4-letter word underneath the motorcycle in the top-left corner of this page". The script currently accepts literally any answer: as long as you type something, the message will get to me (there seem to be two common answers, one of which is right and one which is down to a misinterpretation of "underneath").

Because it's not a standard field, the spambots just leave it blank and the spam is rejected.

I'm not sure why it's a partial derivative when there's only one variable, but that's a lot easier than it looks at first glance.

I could look at that all day, and still be none the wiser. Oh look squirrel. (talking of flying rats. One fell out a tree and glanced of my bike lid yesterday. I was laughing so much watching it hit every branch, it was on me before I knew it)

16 I think.

4 sin (4x - π/2) + 4 cos (4x - π/2) is the same as
4 sin(4x) - 4 cos(4x) : the π/2 offsets make sin into cos and vice versa (with an appropriate sign change) - note I've swapped the order around.
Differentiate that you get 16cos(4x) + 16sin(4x) : the differentiation turns sin into cos and cos into -sin).
sin(N×2×π) is 0 & cos(N×2×π) is 1 for any integer N.
Therefore 16cos(4x) + 16sin(4x) is 16 if x is 2π
