Measuring “Well Being”

We often measure the success of processes with numbers that represent some state of the output or operation of the process. Financial organizations tend to use a “bottom line” number of profitability. But nation-states and some other groups have different purposes and need different measures. When the purpose of a group is to sustain or […]

The Great Filter (Drake/Fermi)

The Drake Equation provides us a means to predict how likely it is that intelligent civilizations may exist. The L-Factor in the Drake Equation represents the length of an intelligent civilization. This is the most significant single factor in the equation. The L-Factor Limits Contact With ET Aliens The Length of a Civilization should be […]

Blockchains are the Foundation for Cyber Currencies

Most have heard of Bitcoin but don’t really understand it. Most have not heard of blockchains and yet, they are the underlying foundation of Bitcoin and other cyber coins. Cyber coins are virtual money tokens and intuitively seem unreliable because they are not backed up by anything similar to the gold standard. The gold standard […]

Cyber Currency – part 5/5 – Summary

SUMMARY A Market example: (our friendly neighborhood farmers market) Barter – direct exchange of goods works well at a small scale, but has limits Limited to a specific time and place No means for deferred payments Dividing some items is difficult or impossible No means for storing value Market example: we decide to create our […]

Cyber Currency - part 3/5 - Blockchain

BLOCKCHAIN A digital ledger or journal of transactions (database) Cryptographic in nature (encrypted) A shared database with write permissions for everybody Validity of transactions is determined cryptographically instead of by a central authority Cryptographic nature Each transaction is combined with the hash value from the previous transaction and a new hash value is calculated Tamper […]

Cyber Currency - part 2/5 - Hashing Algorithms

HASHING ALGORITHMS Hash = one way encryption Uses a mathematical formula (or algorithm) Maps data of variable size to a unique fixed length string Outputs a string called the “hash” or “digest” The same input always produces the same output It cannot be reversed (cryptographic) There are no collisions (no duplicates from different inputs) Hashing […]

Cyber Currency – part 1/5 – Currency Basics

CURRENCY BASICS Barter systems: Involve direct exchange of goods and services Have no intermediate token like money There are some difficulties: The barter process needs a coincidence of two exchange partners (same time, same place) Some trading goods cannot be easily divided into small parts Deferred payments are problematic Storing wealth is not practical Establishing […]

Paperclip Game Demonstrates Automation and AI

This text based game appears simple at first glance. It begins with only one action available: clicking on a button to make a paperclip. But soon you can automate that process with “autoclippers” and then you’re off and flying on a mission to take over everything by turning it all into paperclips. Universal Paperclips [this […]
