The Cetus Extended 3D printer, a Rails-based printing technology has been occupying a great deal of my time as of late. This 3D Printer has a build volume of 180x180x280mm and supports 1.75mm PLA filament.
A very important consideration for children is a printer’s power source. Many 3D printer kits from GearBest, eBay or AliExpress contain open, live wiring that may prove extremely dangerous to children.This printer is a safe choice for children and schools. Cetus ships a kid-friendly power supply that will put to rest any parental concerns. Remember kids are curious. IMHO the Cetus minimalist design provides a better introduction to real hands-on 3D Printing for my children.
Cetus printers have an active Facebook group providing great feedback from a growing community of owners. I am also pleased to see an active Reddit community.
Popular 3D applications Simplify3D, Ultimaker Cura, Slic3r, and Craftware all connect to the Cetus Extended and run very well on an iMac. USB and WiFi are built in and Cetus has an iPad client. The Cetus app will also convert G-code to native machine code before sending objects to the printer.

The Blockchain Basics by Daniel Drescher. This is a very basic blockchain book. I would recommend this to someone completely unfamiliar with blockchain. Daniel hits his mark. Drescher places a repeated template for each step. In this design, I felt the book had trouble flowing for anyone who has already read a blockchain textbook.
Daniel pushes the elementary lessons through 25 steps. There is a very basic outline to the security of the blockchain. Again this book has a specific target audience: Newbie.
I have to admit that I was bored reading the text. yet was impressed by the lessons and related topics that are presented. Yet his lessons and related topics are simple to follow.
For an overall tip of the iceberg, you can fly through this book and then move to Don Tapscott, William Mougayar and Melanie Swan.
Who the Hell Are We Fighting?: The Story of Sam Adams and the Vietnam Intelligence Wars
Who the Hell Are We Fighting?: The Story of Sam Adams and the Vietnam Intelligence Wars is the story Sam’s incomplete memoir War of Numbers could not deliver. Sam Adams died suddenly in 1988 at the age of 54. Sam was a gifted analyst at the CIA. Author C. Michael Hiam delivers a well written narrative of Sam’s life.
Sam displayed the uncommon trait of speaking truth to power. As history often suggests Sam was in the right place at the right time.
His truth revealed outcomes that pitted him against the White House, MACV and even senior leadership within the CIA.
What also made Sam unique was his inability to backdown to the highest offices in the government. Sam created a point of great turmoil by discovering and confronting repeated MACV intelligence failures. His analysis was not supported by CIA Director Richard Helms. Nobody wants to make their boss look bad.
Haim traces Sam’s life from Harvard to a rising star within the CIA to a disillusioned analyst. War of Numbers did not shed light on Sam’s death. Realizing Haim was going to address his passing at the close of the book I dreaded the final chapter to the life of Sam Adams.

Regarded as one of the CIA’s premiere Vietnam intelligence experts George W. Allen wrote a 2001 memoir None So Blind: A personal account of the intelligence failure in Vietnam that remains an alarming insight of intelligence failures that forecasted both France and America’s defeat in Vietnam. Allen’s contributions set the stage regrettably for the Pentagon and White House to also follow France’s misplaced goals in Indochina for the next twenty-five years.
My interest in Allen’s memoir developed from reading a series of confidential reports by the US military and CIA from the 1950s. Declassified in the late 1990s the documents address the French defeat at Dien Bien Phu.
Many of those documents point to Allen’s intelligence reports and analysis. Naturally this peaked my wish to better understand the American intelligence analysis of the French defeat.
Allen holds a unique, deep understanding of the Indochina Wars (France 1945-1950) and the coming failure of America’s intervention on behalf of South Vietnam 1960-1974. The lessons in his book leave deep, haunting impressions today on the White House and Pentagon leaders who ignored our intelligence community.

Decentralized Applications Harnessing Bitcoin’s Blockchain Technology by Siraj Raval is my follow up to three previous blockchain books. This kinda forks hard left after chapter two and drifts.
My first book Don Tapscott’s The Blockchain Revolution was interesting in broad strokes. William Mougayar’s The Business Blockchain was better.
Melanie Swan wrote an even better overview to in her book Blockchain: A blueprint for a new economy. Melanie provides a great overview (looking back from 2015) to address decentralized apps (Dapps), decentralized autonomous organization (DAOs), decentralized autonomous corporations (DACs) and decentralized autonomous societies (DASs). There is such a deeper dive required to wrap your arms around decentralized autonomous blockchains.

Microsoft and Adobe own Tuesdays. Tesla may take over the Wednesday rev cycle as Chinese hackers were able to turn on the model S wipers, open the car doors and even apply the brakes while in motion.
Tencent’s Keen Security Lab posted a video that has gone viral on September 19. Tesla updated an over-the-air software update to their Model S. The Tesla Model S is now running v7.1 2.36.31.
This is not a new issue. Chris Valasek and Charlie Miller hacked a 2014 Jeep Cherokee while on a California highway. Its a sign of thing to come as the Internet of Things continues.
The blockchain is the future of financial infrastructures. An ambitious look at how blockchain can reshape financial services.
The World Economic Forum has posted a PDF view of the Blockchain’s pragmatic impact upon global financial services. Its a very visual read to a great deal of research.
The key areas of focus are blockchain technologies that can push simplicity and efficiency. The opportunity to create new financial service infrastructure based upon high level information security.
The blockchain is looking to launch next generation financial services infrastructure. The report’s use case focus considers how blockchain technology can benefit multiple scenarios across future financial services.
The report is a follow-up to a Deloitte/World Economic Forum report Disruptive Innovation in Financial Services. This report analyzes blockchain across nine sectors of financial services.
When Melanie Swan’s book Blockchain: Blueprint for a New Economy written under the O’Reilly series was available I was eager to start reading. This is a thoughtful overview to the Blockchain. There is much to learn about the role of cryptocurrency and the blockchain but this is not the sole focus of her work.
Melanie, like Tapscott paints a wide brush across the Blockchain. Too similar to Tapscott perhaps? No. If the blockchain’s focus was just security then it would command a smaller, narrow focus on IT infrastructure. Yet Melanie provides a wider arena to learn how Blockchains especially in healthcare hold enormous possibilities.
My first book Don Tapscott’s The Blockchain Revolution was interesting. William Mougayar’s The Business Blockchain was better. My thirst for knowledge continues.This is possibly the best of the three at providing a deeper dive to the possibilities of a truly changing technology.

William Mougayar’s new book The Business Blockchain: Promise, Practice, and Application of the Next Internet Technology provides a blueprint overview that compliments Tapscott’s Blockchain Revolution previously reviewed. Mougayar is able to specifically touch on the Blockchain’s architecture. Tapscott painted with a wide brush addressing everything possible with the Blockchain’s decentralized trust solution.
Mougayar moves slightly forward addressing v 3.0 aimed at audiences wider than banking. A key view is that Blockchain will not just be for the enterprise. This will create a new crypto economy. It will be interesting to watch this grow. Care to take a live look? Here is the blockchain.info site.
He views the blockchain will revolutionize the roles of existing financial intermediaries including PayPal. Blockchains will force change upon them. They can adapt or die like the dinosaurs. Blockchains will disrupt oldschool, imperial organizations as the trust boundary shifts value away from them after hundreds of years.
Banks are clearly the key target of the blockchain infrastructure. To no surprise even the Federal Reserve has been given a blockchain briefing in June. The focus byMougayar beyond another blockchain overview is a breakdown of trust, obstacles and challenges to the Blockchain technology. The issue is much stronger in the financial services marketplace as Wall Street and international banks are now testing blockchains. He touches briefly implementing Blockchain technologies and closes by pushing the message of decentralization as a key in moving forward.

Blockchain as a financial technology (FitTech) surged in late 2015. Wall Street banks and other international financial firms stress tested this technology and are investing in blockchain infrastructure. Even Janet Yellen and The Federal Reserve received a blockchain briefing within June.
Don Tapscott’s Blockchain Revolution: How the Technology Behind Bitcoin Is Changing Money, Business, and the World is a worthy introduction to this advanced security ledger technology. This book is NOT about Bitcoin.
Tapscott paints with a wide brush across the underlying architecture. Looking for blockchain infrastructure, cryptocurrency or blockchain as a service than take a glance at the table of contents. O’Reilly’s Blockchain books are more targeted to tech folks anyway.
Hard to believe I have been a fan of Don’s writing for over 10 years. Just looked at my review of Wikinomics and MacroWikinomics, his previous books published way back in 2006. His follow up Macrowikinomics was released in 2008. It was interesting to me to understand Don lightly wrapped an element from Wikinomics called Ideagoras into The Blockchain Revolution. Sometimes you just cannot leave home….
Clearly FinTech sees the blockchain’s potential to disrupt their world. The focus for Tapscott is how to address Blockchain beyond Wall Street. The blockchain allows participants of public and private distributed systems to agree on a common view of a system and track changes across those systems with highly secure encryption. Security is also the core of healthcare blockchains with the focus on the crypto in cryptocurrency.

Have been looking forward to Tom Davenport’s Keeping Up with the Quants: Your Guide to Understanding and Using Analytics for longer than I care to admit. I throughly enjoyed his book Competing on Analytics all the way back in 2008. His followup Big Data@Work provides the same scope for business regarding the emerging era of Big Data.
Tom has truly mastered the role of business analytics for well over two decades. He is acknowledged as revealing the path of metrics and just as important how success can be defined by adopting a mindset of analytics over intuition. It should be no surprise that I am a big fan of Tom Davenport.
Seems like a lifetime ago in the competitive and fast changing world of analytics. Quantitative analysis with a side of regression is not a diner order but a key skill to identify patterns in data.
An easy read with great common sense approaches for leaders to understand and professionals to embrace it proves not only how business gains insights but how to defend Kobe Bryant.
On the heels of reading Nate Silver’s bestseller The Signal and the Noise, Davenport reveals how quants have not only broken down NBA basketball defensive measures to each quarter when playing Bryant and the Lakers but how to guard him in a last possession game scenario.

Superforecasting: The Art and Science of Prediction by Wharton’s Philip Tetlock and Dan Gardner is another great read addressing analytics, human behavior and analytic technologies for establishing and sharpening forecasting abilities for any organization.
The book title is a wonderful attention grabber for me that demonstrates we live in the era of big data with business driving the age of immediacy.
Superforecasting acknowledges data lessons supplied by Nate Silver’s The Signal and the Noise as helping to define standards to data and how it misled the national media.
Yet just into the second chapter Tetlock and Gardner point to the research by Daniel Kahneman excellent work Thinking Fast and Slow to help determine behaviors shaped over time that have fundamentally changed how we predict success.
