Cetus Extended 3D printer

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.
Cetus Extended
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 Simplify3DUltimaker 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.

Latest Read: Blockchain Basics

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 as he 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.
Blockchain BasicsDaniel 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.

Latest read: A War of Logistics

What really caused France’s humiliating loss to the Viet Minh in the French Indochina war? To understand we must focus on logistics. Charles Shrader’s A War of Logistics: Parachutes and Porters in Indochina, 1945–1954 reveals the true staggering failures of the French were simply the result of poor logistics.
A War of Logistics: Parachutes and Porters in Indochina, 1945--1954 (Foreign Military Studies) by Charles R. ShraderOn the surface, it may not make sense. A western power falling to an agrarian band of guerrilla fighters? No author has precisely examined Viet Minh and French military logistics in great detail. This is an impressive view.

Shrader has taught at West Point, the Command & General Staff College at Fort Leavenworth, and at the Army War College. He is a former executive director of the Society for Military History. His metrics and well-written history document those French military pillars that collapsed triggering their retreat not only from Indochina but from the world stage.

Many respected books point to Dien Bien Phu as the surprising French loss and later defeat in the war. Shrader documents how this battle was the culmination of a series of shocking logistical failures that plagued their efforts against the Viet Minh.

The shift benefitting the Viet Minh developed after the Korean War. China began delivering overwhelming logistical resources to the Viet Minh. While French and CIA intelligence captured communications confirming numerous deliveries of infrastructure, France did not adjust to this threat.

In retrospect, the logistical failure to support the French effort should have sent strong signals to American military advisors that success against this communist enemy would be a long and difficult task.

Latest read: Operation Vulture

Operation Vulture by John Prados reveals President Eisenhower’s plans to use nuclear weapons at Dien Bien Phu to “rescue” the French garrison. An analyst of national security based in Washington DC, he is a Senior Fellow and Project Director with the National Security Archive at George Washington University where he leads the Archive’s documentation projects on Vietnam and CIA.
Operation VultureThe US National Archive has released multiple classified documents since 2000. We now understand Eisenhower’s deep involvement. He ordered the US military into the First Indochina War in 1953. Prados reveals startling details of Eisenhower’s wish to use nuclear weapons and his order to the US Air Force and Navy bringing a nuclear weapons attack upon the valley as the French garrison was being quickly suffocated by the Viet Minh.

The details of those military actions moving men and arms throughout Vietnam, Laos, and Cambodia along with the international political maneuvering by Allen Dulles in the early 1950s dispels any myth that America simply went to war in Vietnam under President Kennedy.

Prados stitches an enormous amount of Eisenhower’s actions regarding Vietnam beginning in 1953. Eisenhower acted on his view of the world that required a strong American confrontation in Asia to offset China.

Latest read: Who the Hell Are We Fighting?

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.
Who the Hell Are We Fighting?: The Story of Sam Adams and the Vietnam Intelligence WarsSam 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 discuss his passing at the close of the book I dreaded the last chapter to the life of Sam Adams.
