  1. Decade of cybersecurity data could predict future malicious online activity - Last Thursday (Oct 3), researchers announced the release of a public database containing records of mal-activities from 2007 through 2017. The so-called mal-activity reports were categorized into six groups: "Malware, Phishing, Fraudulent Services, Potentially Unwanted Programs, Exploits and Spamming". It is hoped that the database will enable researchers to study the ways that sources, scale, and types of mal-activities have changed across time. h/t Communications of the ACM

  2. Money Is A Technological Fiction (The Invention of $$$) - Describing money as a medium of exchange and a way to store value by making use of standard units of accounting, the It's Okay to Be Smart YouTube channel walks through the history of money. The video starts with ancient technologies like barter, stone tablets, and cowry shells, then moves forward to metal coins, paper receipts, and fiat money that originated in 12th century China. In the modern era, it covers forms of electronic money including wire transfers, credit cards, and even bitcoin and other cryptocurrencies. h/t RealClear Science

    To save you a click, here is the video

  • These are the deepest and largest man-made holes in the world - People began drilling to reach the Earth's mantle in the 1960s. As with the space race, competition began between the US and the USSR. It has been hoped that by digging to the mantle, scientists could realize a better understanding of the Earth's core. No one has accomplished it yet, but scientists keep trying. The US dug to a depth of 600 feet below the ocean's floor in the 1960s before the project was deemed too expensive, and the congress cut funding. From 1970 through 1992, the USSR and Russia dug to a depth of 40,230 feet, but had to stop because of the heat. Their hole, the "Kola superdeep borehole", is 9 inches in diameter. It was capped in 1992, and it's still the deepest man-made hole today. Germans entered the fray in 1990, and achieved a depth of 30,000 feet. Starting in 2002, Japan reached a depth of about 2 miles (~10,500 feet) before closing up shop in 2019 because of the heat. Because the Earth's crust is thinnest at the bottom of the ocean, many of these efforts have been undertaken at sea. Unexplained strange noises have been observed and recorded coming from several of the holes. The only exposed portion of the Earth's mantle is in the al-Hajar mountains in Oman, but the exposed area is millions of years old, so it is not representative of the active mantle today. This article contains numerous photos and descriptions of the sites, and after the sections on drilling for the mantle, it also goes on to cover other drilling efforts like ice-drilling in Antarctica and a diamond mine in Russia.

  • EOS Developer Block.one Releases Version 2.0 of EOSIO Protocol - Block.One has introduced EOSIO 2, which - the company says - includes smart contract improvements in efficiency and security, as well as new tools for developers. One of the key new tools is the alpha version of their EOSIO Quickstart Web IDE. They claim that the updated EOS VM provides a 16x performance improvement over the version 1.0 product. A security improvement is the ability to use a hardware device for web authentications without the need for a browser plugin.

  • STEEM One Year of Steem Powered on Grid Solar System Performance Results - In this post, @moon32walker reports the results of running an on-grid solar collector for a year. The solar panel was purchased with funds that were earned through the Steem blockchain. The post reports that - after three months of difficulty with faulty parts - the solar panels have generated 4,700 kWh and reduced the monthly electric bill by about 80%. The post also notes that, because the collector is on-grid, it doesn't have a battery. Instead, any excess power generation goes back into the grid for use by other consumers. (A 10% beneficiary setting has been applied to this post for @moon32walker.)

    • In order to help make Steem the go to place for timely information on diverse topics, I invite you to discuss any of these links in the comments and/or your own response post.
