Inside the Hidden World of Elevator Phone Phreaking. The True “Aboutness” of Blockchain and Why We Are All Crypto Sherpas. Using Phenomenology to explain, not just describe what blockchain really is Most Blockchain explanations are actually descriptions and they are confusing As a Medium reader you will find endless posts explaining Blockchain.
Yuval Noah Harari on Why Technology Favors Tyranny. Editor’s Note: This article is part of a series that attempts to answer the question: Is democracy dying? I. The Growing Fear of Irrelevance There is nothing inevitable about democracy. For all the success that democracies have had over the past century or more, they are blips in history. Monarchies, oligarchies, and other forms of authoritarian rule have been far more common modes of human governance.
The emergence of liberal democracies is associated with ideals of liberty and equality that may seem self-evident and irreversible. In the second decade of the 21st century, liberalism has begun to lose credibility. Information technology is continuing to leap forward; biotechnology is beginning to provide a window into our inner lives—our emotions, thoughts, and choices.

Buy it here. (Or see a preview.) Note: The reason this post took three weeks to finish is that as I dug into research on Artificial Intelligence, I could not believe what I was reading. It hit me pretty quickly that what’s happening in the world of AI is not just an important topic, but by far THE most important topic for our future. At Scale, Rare Events aren’t Rare – Perspectives. I’m a connoisseur of failure.
I love reading about engineering failures of all forms and, unsurprisingly, I’m particularly interested in data center faults. Linux nslookup command help and examples. Updated: 04/26/2017 by Computer Hope About nslookup The nslookup command is used to query internet name servers interactively for information.
Overview nslookup, which stands for "name server lookup", is a useful tool for finding out information about a named domain. By default, nslookup will translate a domain name to an IP address (or vice versa). Nslookup microsoft.com.

He died earlier this year in Silicon Valley after a long fight with Parkinson’s disease. When one of the most powerful people in the world encourages us to be paranoid, maybe we should listen. And Grove isn’t the only powerful person urging caution. Even the director of the FBI — the same official who recently paid hackers a million dollars to unlock a shooter’s iPhone — is encouraging everyone to cover their webcams. But you obey the law. Well, law-abiding citizens do have reason to fear. Detailed VPN Comparison Chart.

Summary Many computers emit a high-pitched noise during operation, due to vibration in some of their electronic components.
These acoustic emanations are more than a nuisance: they can convey information about the software running on the computer and, in particular, leak sensitive information about security-related computations. In a preliminary presentation, we have shown that different RSA keys induce different sound patterns, but it was not clear how to extract individual key bits. The main problem was the very low bandwidth of the acoustic side channel (under 20 kHz using common microphones, and a few hundred kHz using ultrasound microphones), many orders of magnitude below the GHz-scale clock rates of the attacked computers. Here, we describe a new acoustic cryptanalysis key extraction attack, applicable to GnuPG's current implementation of RSA.
