Analog Is Back from the Future at CES
"Forget hoverboards, fridges that talk to the Internet, and self-driving cars.
Three of the most popular items at this month's annual Consumer Electronics Show in Las Vegas -- a cine camera, a record turntable and a new
Polaroid snapper -- suggest there's a back-from-the-future movement gaining ground that reflects a growing fatigue with the virtual world of
digital products, and a renewed enthusiasm for the old-fashioned analog experience ..."
Potential of Graphene Nanoribbons in Electronics Gets a Boost
"If graphene is going to make
a splash in electronics, it more than likely is going to be in the form of nanoribbons.
What makes them attractive is that their width determines their electronic properties: Narrow ones are semiconductors, while wider ones act
as conductors. This essentially provides a simple way to engineer a band gap into graphene. Last summer, this blog reported on news that a bottom-up
approach to manufacturing graphene ..."
I Think Therefore I Am … a Patent
This article by
Annie Dike, writing for IMS ExpertServices,
discusses patentability of computer algorithms and the mostly subjective tests applied by courts when determining veracity of claims. Per Ms.
Dike's assessment, a 'Thought Police' aspect of adjudication is employed by justices, often in courtrooms where the only people truly qualified
to render informed decisions are the plaintiff, defendant, and various experts in the field. For many judges, the 'you don't know what you don't
know' scenario exists, meaning that while he/she may be brilliant concerning objective law, not being well versed in requisite technical issues
can result in a judge not realizing how deficient in knowledge he/she is. The 'Alice' decision referenced in her article includes

AppCAD 4.0: An Updated Blast from the Past
Many of the old-timers out there will fondly
remember Hewlett-Packard's AppCAD software back in the days when DOS was king. AppCAD was originally released in 1990 by Hewlett-Packard as
version 1.02. I remember receiving it on a 5-1/4" floppy disk from an HP application / sales engineer while working at GE in Utica, NY. Everyone
in the office wanted a copy. That was the era when IBM XT's ATs, Gateway, and Packard Bell PCs ruled. The latest version,
AppCAD 4.0, was released sometime in 2012 according to the copyright date listed in the Help->About
AppCAD window. It claims Windows 7/8 compatibility, and I've confirmed that it does just fine in Windows 10 as well. The original

Has the security of the United States' Global Positioning System

riverine craft with advanced technology has been captured by the Iranians. We have recently agreed to give Iran billions of dollars
in seized funds and assist them with their nuclear program. Videos show Iranian military types surveying their spoils of war. Our sailors suffer

How to Make the World's Smallest 3-Tube Radio Set
My first thought
when seeing the cover for this edition of Radio-Craft magazine was that it was an April Fools gag, but it turns out the 'hat' being worn by
the radio receiver's designer is a
loop antenna for AM reception. In a way it is the opposite of a tinfoil hat in that this headgear invites electromagnetic energy around
the wearer's head rather than shielding it. Back in 1936, being seen in public donning a contraption like this radio would have been akin to
Google Glass today - you'd be a superhero to fellow nerds, and just be confirming your otherworldly nerd status to non-nerds
