How Green Power Powers the Cryptocurrency Mining Future

Elizabeth Gail Crypto miners are going to extraordinary lengths to bring down the costs of cryptocurrency mining, as hashrates reach historic highs and prices struggle to move beyond market resistance. The situation has forced out less efficient miners, with the sector now being dominated by big players with millions of dollars to invest in low-cost, … Continue reading How Green Power Powers the Cryptocurrency Mining Future

Cyber security: Unpredictable Random Number Generator

Random Number Generator is an important factor of security activity to create cryptographic keys and passwords. We already know that the rand() function is a simple pseudo-random number generator. It returns a pseudo-random integer in the range 0 to RAND_MAX, ie, the mathematical range [0, RAND_MAX]. You can use rand() to define your own function … Continue reading Cyber security: Unpredictable Random Number Generator

Cyber security: Monitor file integrity

In addition to ClamAV antivirus, Omarine 4.0 provides Tripwire package to monitor the integrity of the files in the system. The monitoring policy is derived from /etc/tripwire/twpol.txt, a plain text file that you can edit. To use tripwire you first create the site key and local key: sudo twadmin -m G -L /etc/tripwire/$(uname -n)-local.key \ … Continue reading Cyber security: Monitor file integrity

Bitcoin Bubble? Why the Burst Might Be Good for Bitcoin & Blockchain

Bennett Garner Media outlets that once ran glorifying stories of Bitcoin ascendance are now describing a Bitcoin bubble that has popped. Economists who were at first curious in a new type of monetary system are now foretelling panic. In this strange climate after a fall from great heights, it’s worth considering how we got here … Continue reading Bitcoin Bubble? Why the Burst Might Be Good for Bitcoin & Blockchain

Cyber security: How to turn a non-TLS aware server into communicable with clients over secure TLS channels without server configuration?

Although we can easily configure the web server to listen to port 443 for https, this article uses the default configuration of the web server in Omarine 4.0, ie, not listening to port 443, to illustrate the case. No need to configure the server. We use stunnel to do that. We experiment on a local … Continue reading Cyber security: How to turn a non-TLS aware server into communicable with clients over secure TLS channels without server configuration?

Football Predictions 2.0: Why use id3 to create checking samples?

Football Predictions uses neural network so a checking sample set is needed to evaluate the network configuration. The checking samples can be part of the problem's sample set and the network will learn the rest. But this way is not good because the network will not be fully learned and may have big errors. The … Continue reading Football Predictions 2.0: Why use id3 to create checking samples?

Football Predictions 2.0: Watch a video on Machine learning

There are 4 hidden nodes used. The process goes through 20 rounds with 20 neural network populations. If necessary, the next 20 rounds will be processed with a doubled number of hidden nodes, which is 8. However, in this example there are no rounds with 4 hidden nodes failing, so using 4 hidden nodes is … Continue reading Football Predictions 2.0: Watch a video on Machine learning

Ethereum Classic | Beginner’s Guide

Paul Andrew What is Ethereum Classic? Ethereum Classic is the original Ethereum blockchain and allows for the implementation of decentralized applications and smart contracts. The project was born out of an unwavering belief in core principles. It symbolizes the importance of a cryptocurrency being fungible and its blockchain immutable. The Ethereum and Ethereum Classic blockchains … Continue reading Ethereum Classic | Beginner’s Guide

Football Predictions 2.0 released!

This is a great version. The program uses ID3 algorithm to generate some checking samples. Many neural network populations are processed with different number of hidden nodes, and through a number of different weight initialization. The populations evolve to their fixed point, when all neural networks have converged, the errors on the checking sample set … Continue reading Football Predictions 2.0 released!

Football Predictions – id3 released!

The id3 program is intended to create checking set for Football Predictions 2.0. However, it can also run independently. Using id3 is similar to fpp, edit fppdata.txt and run this command: ./id3 For details on the id3 algorithm, see this article, please translate into your language. This is a snapshot of the tennis problem And … Continue reading Football Predictions – id3 released!
