Bob Proposes Diffie Hellman

Description

A "TRADE OFFER" meme shows a man in a suit under purple lighting with a label on his forehead reading "Bob". The left side says "i receive:" above the formula "g^a mod p", and the right side says "you receive:" above "g^b mod p". The meme maps the trade-offer format onto a Diffie-Hellman-style key exchange, where parties swap modular exponentiation values to derive a shared secret without directly sending it.

The meme shows a decryption error

IF (month = 2 AND day = 29) AND ((year MOD 4 <> 0) OR ((year MOD 400 <> 0) AND (year MOD 100 = 0 ) AND mark$ = "G")) THEN GOSUB 5: GOTO 2 ELSE GOTO 3 EDIT: Translated variable names to English

  the question remains still

  I wanted to say, it's useless to show it, but.. 3 : mark = FIX(year \ 100) r = -1 FOR i = 15 TO mark IF FIX(i / 4) <> i / 4 THEN r = r + 1 NEXT i IF year / 100 = FIX(year / 100) AND year / 400 <> FIX(year / 400) THEN r = r - 1: mark = r

  yey, 3

  bruh im too high to figure this out
  
  @ANTICHRISTUS_REX 5y
  
  it's a part of my very old essay, the Universal Calendar. it gives clues to make calendars of any year since 45 BC → ~4500 a.D.~ (limited by the actual Julian & Gregorian Calendars). The first part of this code searches for errors in the input data (if it's really a leap year or not). (month = 2 AND day = 29) AND ((year MOD 4 <> 0) the second part helps to know if the leap day will be truncated or not (specific cases only applied within the Gregorian Calendar). ((year MOD 400 <> 0) AND (year MOD 100 = 0 ) AND mark$ = "G")) For more details, you firstly need to understand how the current calendar works, and for details about the program, feel free to contact me in private, to give you the full code, and the way to run it.
@dmytro_kp 5y

Explain pls
1. @ANTICHRISTUS_REX 5y
  
  it's a programming jokes and memes channel. To understand, we firstly need to know the used language.. Then to 'capiche' te joke.
  
  @dmytro_kp 5y
  
  My bad, I'm JS dev and this meme seems to be so unrelated to my native language 😒
  
  dev_meme 5y
  
  js devs be like "sorry, SQL is backend"
  
  dev_meme 5y
  
  nvm I thought we were talking about @ANTICHRISTUS_REX's SQL snippet
  
  @ANTICHRISTUS_REX 5y
  
  It's the BASIC language, antediluvian programming 🥺.
  
  @dmytro_kp 5y
  
  I feel personally attacked
  
  dev_meme 5y
  
  Don't worry, I'm a frontend dev as well. Can't do jackshit with SQL.

  it's maybe dead now, there was an update coming with framebuffer devices, but not anymore i guess
@solwayfirth8956 5y

the twist is, a = b
dev_meme 5y

really? I'm gone for 10 minutes and some spam bot immediately joins? bruh
1. Deleted Account 5y
  
  make a bot that will filterspam
  
  dev_meme 5y
  
  on one hand, that's kinda hard to do, and on the other, I'm not the one to ask this. I'm just a mod, not the admin.
  
  dev_meme 5y
  
  I don't think that we'll need rose or a similar bot in the near future anyway.
  
  Deleted Account 5y
  
  nah, not like rose, but just basic validator like "to koin press the button"
  
  dev_meme 5y
  
  …I'm not sure how that would work. And the bots could still just post stuff in the comment sections of the main channel.
  
  Deleted Account 5y
  
  damn, at least the report command then
  
  dev_meme 5y
  
  I'll see what I can do
  
  dev_meme 5y
  
  for now, just ping @RiedleroD (which is mee), so I get a message.
  
  Deleted Account 5y
  
  YOoooo dass yoou
  
  dev_meme 5y
  
  yeesh das mee :))) admin just PMd me one day and asked if I wanna be mod.
  
  Deleted Account 5y
  
  and now you're anon
  
  dev_meme 5y
  
  aye. I kinda like it ngl. But I'll probably ask admin to turn it off eventually.
@chverma 5y

It's the fucking bob, the man in the middle... He knows how to change our message.
@dmytro_kp 5y

You know, after 50+ comments on this post I guess that meme was just a bait for increasing activity
