Orb of Osuvox vs Cataclyst – Ready Player One

What would happen of the Cataclyst had gone off inside the Orb of Osuvox? Also, what would happen if the Cataclyst were to go off on the outside perimeter of the shield created by the Orb of Osuvox? Would the barrier of the orb take the damage or would the Cataclyst prevail?


Warning network engineers

Due to the Coronavirus disease (COVID-19) all TCP applications have to be converted to UDP to avoid Handshakes.

The TCP handshake

TCP uses a three-way handshake to establish a reliable connection. The connection is full duplex, and both sides synchronize (SYN) and acknowledge (ACK) each other. The exchange of these four flags is performed in three steps: SYN, SYN-ACK, ACK.

2 = 1 ?!? — not really

As many people, we came across the following photo:

False proof that 2 = 1

In this mathematical “proof” the author tries to convince us that there is an error in math and it can be demonstrated using the above example. The steps taken by this person are the following:

  1. The proof starts by defining a equal to b (a = b).
  2. Then, it multiplies both sides with a which results to a^2 = ab.
  3. Next, it subtracts from both sides b^2 and we get a^2-b^2 = ab-b^2.
  4. Following, it extracts the common multiplier of both sides (a-b) resulting to (a+b)(a-b) = b(a-b).
  5. Here’s the nice part, the author divides both sides with (a-b) which results to a+b = b.
  6. Since a = b, it replaces a on the left side with a b and produces this state b+b = b => 2b = b.
  7. Finally, it divides by b both sides which results to 2 = 1.

The reason that this proof is false is because in step 5, where it divides both sides with (a-b) it really is dividing both sides with 0 (since we know for sure that a = b from step 1) which it cannot be defined as a valid division. So everything from step 5 and forward are invalid and thus the proof is wrong.
