A Green Powered Sailboat — Hackaday

Drones fill the sky raining hellfire on unsuspecting civilians below. Self-driving cars only cause half as many accidents as carbon-based drivers. Autonomous vehicles are the future, no matter how bleak that future is. One thing we haven’t seen much of is autonomous marine vehicles, be they submarines, hovercrafts, or sailboats. That’s exactly what [silvioBi] is building for his…

How to explain the value of replicated, shared ledgers from first principles

Richard Gendal Brown

“Digital currencies” aren’t needed to explain why distributed ledgers are important.

In this post, I develop an argument for replicated shared ledgers from first principles. It is intended to be an “education piece” aimed at those, particularly in the finance industry, who prefer explanations of new technologies to be rooted in a description of a real-world business problem rather than beginning with a description of a purported solution.  So, in this piece, you’ll find no mention of digital currencies, etc., because it turns out you don’t need them to derive an argument for distributed ledger technologies!

(Note to regular readers: see the end of the piece for some context)

We’ll start with banking systems

Start by thinking about today’s banking systems. In what follows, I use a bank deposit and payments example. But the same logic applies everywhere you look, as I’ll argue later.

Let’s imagine a world with three banks: Bank…

Real estate firms rapidly adopting new lead gen tool

Remodeling network Porch has unveiled a second tool that brokerages, website providers and listing search services can use to augment listings with renovation project history reports, and squeeze more leads out of real estate websites.

A number of leading real estate companies have already adopted the widget, highlighting the appeal of the latest lead-capture feature to become available to real estate websites. AddressReport is another property report provider that recently fashioned a lead generation product for real estate firms.

Prospective buyers that visit listing pages equipped with Porch’s new widget may click the add-on to pull up a Porch report detailing the listing’s remodeling project history.

Companies that embed the widget on their websites can gate the property report behind a form that requires a user to enter their contact information. They can also add their branding or a real estate agent’s branding to the reports.

The integration “creates the ability to drive meaningfully more leads” through a real estate search website, said Porch CEO Matt Ehrlichman.

How Real Estate Uses Big Data to Track Clients

To target prospective clients, tech-savvy agents are buying data subscriptions and teaming with startups

Sitting in bed at 1:40 a.m. one morning last November, Jon Hoefling was thinking about selling his 4,300-square-foot home in Morgan Hill, Calif. While browsing Facebook on his phone, he clicked on a real-estate ad offering to estimate his home’s value. His future listing agent, who paid for the ad, was waiting.

Mr. Hoefling, the 50-year-old owner of an office-furniture resale company, had been targeted for the ad—along with 1,500 others in California’s Silicon Valley area—by an algorithm that identified him as a likely home seller. The telltale signs: Mr. Hoefling has lived in the home for more than 15 years, and his home’s market value is high for the area. Most important, his youngest son will soon leave for college. Empty nesters might as well wear a bull’s-eye.

Stephen Hawking predicts robot apocalypse coming within 100 years

Terminator
If you thought the title villain in Avengers: Age of Ultron was scary: just wait, because one of the biggest brains on the planet thinks a robot takeover is likely in the next century.

Renowned physicist Stephen Hawking appeared at the Zeitgeist 2015 conference in London and confirmed the fears held by anyone who has watched a movie with a robot in it since 1927’s Metropolis when he said, “Computers will overtake humans with AI at some within the next 100 years. When that happens, we need to make sure the computers have goals aligned with ours.”

Earth Day: Environmental Sensors

Hackaday

Before you attempt to solve a problem, you must first study the problem. If there’s a problem with the environment, you must therefore study the environment at a scale never seen before. For this year’s Hackaday Prize, there are a lot of projects that aim to do just that. Here are a few of them:

[Pure Engineering]’s C12666 Micro Spectrometer has applications ranging from detecting if fruit is ripe, telling you to put sunscreen on, to detecting oil spills. Like the title says, it’s based on the Hamamatsu C12666MA spectrometer, a very tiny MEMS spectrometer that can sort light by wavelength from 340 to 780nm.

The project is to build a proper breakout board for this spectrometer. The best technologies are enabling technologies, and we can’t wait to see all the cool stuff that’s made with this sensor.

[radu.motisan]’s portable environmental monitor isn’t just one sensor, but an entire…

FCC Creates Innovation Radio, The Future Of Wireless Broadband

Hackaday

Thirty years ago there was a lot of unused spectrum in the 900MHz,  2.8GHz, and 5.2GHz bands. They were licensed for industrial, scientific, and medical uses since their establishment in 1947. But by the 1980s, these bands were identified as being underused. Spectrum is a valuable resource, and in 1985, the FCC first allowed unlicensed, spread spectrum use of these bands. Anyone who has ever configured a router will know the importance of this slice of spectrum: they’re the backbone of WiFi and 4G. If you’re not connected to the Internet through an Ethernet cable, you have the FCC Commissioners and chairpersons in 1985 to thank for that.

Last week, the FCC unanimously voted to allow the use of spectrum in the 3.5GHz band with the Citizens Broadband Radio Service. This opens up 150 MHz of spectrum from 3550 – 3700MHz for new wireless broadband services. If history repeats…
