These were ordinals that were only indexed in later versions of the script. So to prevent changing the useless indices of existing ordinals, they gave them negative numbers.

Connect two computers directly without a router with an Ethernet cable Updated 2025-07-16
For IP-level communication, askubuntu.com/questions/22835/how-to-network-two-ubuntu-computers-using-ethernet-without-a-router/116680#116680 just worked between P51 and P14s both on Ubuntu 23.10 connected with a regular Cat 5e cable.
On both machines, first we found the Ethernet cable interface name with the which outputs on the P41s:so the interface was
ip CLI tool:ip a1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

sudo ip address add 10.0.0.10/24 dev enp1s0f0Then on the P51 analogously, giving IP of 10.0.0.20 to the P14s:
sudo ip address add 10.0.0.20/24 dev enp0s31f6And after that, P14s can:and P51 can:

Cool data embedded in the Bitcoin blockchain We are 256, We are 1 Updated 2025-07-16
"WE ARE 256, WE ARE 1" is an invitation to a Discord-based puzzle game with the promise of a money prize of unspecified value in Round 10.
It is written as a short mystery story/cult invitation/tabletop RPG with some mysterious Braille Unicode art cabal symbols thrown in, nice work, e.g. the first one:

Amidst the labyrinthine trials, the ultimate test lies in Round 10, where grand prize money riddles await the most skilled and dedicated participants.
In this cryptic journey, the number of 256 Ordinals held becomes a key determinant of progress. Those who hold a higher number of Ordinals, standing as sentinels of wisdom, enjoy an edge over others. They are safeguarded from regressing beyond their current round, their position secured by the strength of their holdings.However, for those who possess fewer Ordinals, a different fate may await. Purges, shrouded in mystery, can demote participants to lower rounds, challenging them to rise again through determination and resolve. The path to enlightenment demands resilience and the tenacity to overcome setbacks.
Finally further down we see some join instructions:And finally they give concrete join instructions at:Removing the spaces it is just Base64:giving:so perhaps there is a hidden message in that text to actually access the Discord?

xsel -b | tr -d ' ' | base64 -dIn the hallowed chambers of 256, a select group emerges from the depths of knowledge and mastery. As we ascend through the challenging rounds and unravel the enigmas that lie within, a council of visionaries begins to take shape. These luminaries, the Illuminated Ones, are the chosen few who have delved deepest into the mysteries, unlocking the secrets that bind our shared destiny.To join the ranks of the Illuminated Ones is to embrace the challenge laid before us. It requires unwavering determination, relentless pursuit of knowledge, and an insatiable curiosity that drives us to unlock the hidden depths of the Watch Tower. As we decode the cryptic puzzles and navigate the labyrinthine maze, we become catalysts of change, shaping the very fabric of our collective future.Only the smartest, the most intrepid, and the boldest souls will find themselves welcomed into this secret council. They are the ones who have traversed the treacherous terrain, tested their mettle, and emerged triumphant. With each step forward, they gain insights and wisdom that have the power to reshape the very landscape of the digital realm.Curious and courageous souls are invited to join the ranks of the Illuminated Ones. Those who dare to challenge the boundaries of what is known and venture into the realm of the unknown are the ones who will find their rightful place among the visionaries and leaders of the 256 community. Together, we wield the power to shape our shared destiny, to create a future where decentralization, privacy, and the principles of Bitcoin reign supreme.
