  • The Seven Rs of Effective Editing

    Each "Communication Corner" essay is self-contained; however, they build on each other. For best results, before reading this essay and doing the exercise, go to the first essay "How an Ugly Duckling Became a Swan," then read each succeeding essay.

    This essay is based on an article originally published in 2012. Although aimed specifically at journalists, it contains considerable good advice for all expository (non-fiction) writers. Not the least because it twice cites advice from my book The Gettysburg Approach to Writing & Speaking like a Professional.

    I have edited the original text to direct it away from the fast and furious world of news reporting to adapt its very useful advice to the slower, more reflective pace of most other writers not subservient to daily deadlines. In most cases, my editing has shortened the text.

  • Electricity Consumption by ICT: Facts, trends, and measurements

    This paper considers key issues surrounding energy consumption by information and communication technologies (ICT), which has been steadily growing and is now attaining approximately 10% of the worldwide electricity consumption with a significant impact on greenhouse gas emissions. The perimeter of ICT systems is discussed, and the role of the subsystems that compose ICT is considered. Data from recent years is used to understand how each of these sub-systems contribute to ICT's energy consumption. The quantitatively demonstrated positive correlation between the penetration of ICT in the world's different economies and the same economies' contributions to undesirable greenhouse gas emissions is also discussed. The paper also examines how emerging technologies such as 5G, AI, edge computing, and cryptocurrencies are contributing to the worldwide increase in electricity consumption by ICT, despite the increases in ICT efficiency, in terms of energy consumed per bit processed, stored, or transmitted. The measurement of specific ICT systems' electricity consumption is also addressed, and the manner in which this consumption can be minimized in a specific edge computing context is discussed.
