Venus terraforming plan by Allen Young.Here's how I plan to terraform Venus for interplanetary mass human migration to Venus, within the next few decades hopefully.Mass-scale outer space humanity expansion of any kind—be it interplanetary, interstellar, or intergalactic—cannot happen without nuclear-fusion reactors powered interplanetary spaceships. I'm absolutely sure of that.(Early-plugs insertion point. A few seconds of silence in audiovisual.)So the first order of business in enabling terraforming Venus is developing one or more commercializable nuclear-fusion reactor technologies that will produce vastly more energy than the energy put in.Secondly, nuclear-fusion reactors powered interplanetary spaceships must be developed and commercialized for terraforming Venus.Thirdly, nuclear-fusion reactors powered Venus atmosphere terraforming technology must be developed for terraforming Venus. The Venus atmosphere is almost purely carbon dioxide, the green house gas that traps heat. The current Venus atmosphere of carbon dioxide, CO2, must be transformed into water, H2O, and solid carbon using hydrogen and nuclear-fusion reactors powered molecule recombination technology; the Venus atmosphere must be transformed into the Earth atmosphere, which is 78.08 percent nitrogen, 20.95 percent oxygen, and 0.93 percent argon.Fourth, if and as needed, the Venus surface crust must be terraformed into the Earth surface crust, by nuclear-fusion reactors powered industrial spaceships and robots, so that plants can grow and animals can live on Venus surface.The needed raw materials for terraforming Venus atmosphere and crust can be harvested by fully autonomous nuclear-fusion powered interplanetary spaceships and AI-enabled robots, from Venus crust, other planets, planetary moons, and/or Sun's surface, and be transported to where they are needed above Venus in the terraforming Venus atmosphere.Fifth, plant and animal growth-acceleration biotechnologies must be developed and commercialized for quickly populating the Earth-like-atmosphere-and-crust Venue surface with floras and faunas, in less than a year.It will take quite a bit of nuclear-fusion reactors powered outer space tech and biotech development work with regulatory approvals to make the Venus terraforming happen; I'm sure Robocentric Outer Space division will eventually get to terraforming Venus for all of humanity to use.

Currently, in AD 2023, Java Spring Boot is the most popular backend web app software development framework with over 50% market share. I think knowing how to use Java Spring Boot is a must-have skill in software development nowadays.Java Spring Boot is built on the top of the Spring platform.According to the official statement at spring.io/projects/spring-boot, Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run".(Early-plugs insertion point. A few seconds of silence in audiovisual.)To the best of my knowledge, Java Spring Boot is mostly used to implement REST API backend server. I don't know yet what other types of applications Java Spring Boot can be used to implement, if any, other than REST API backend server.Spring Boot has two major official references at spring.io/projects/spring-boot#learn, Reference Doc and Api Doc.The Spring Boot Reference Doc has the following copyright terms. "Copies of this document may be made for your own use and for distribution to others, provided that you do not charge any fee for such copies and further provided that each copy contains this Copyright Notice, whether distributed in print or electronically."The Spring Boot Api Doc is a Javadoc with the documentation in the Spring Boot source code. Spring Boot is an open-source project at github.com/spring-projects/spring-boot with Apache License 2.0.So, so long as I don't charge any money, I can distribute any portions of both the Spring Boot Reference Doc, and the Spring Boot Api Doc.As a part of my Java Spring Boot learning process, I'll go over the Spring Boot Reference Doc and Api Doc.The Spring Boot reference documentation consists of the following sections.Using Spring Boot: Build Systems, Structuring Your Code, Configuration, Spring Beans and Dependency Injection, DevTools, and more.Core Features: Profiles, Logging, Internationalization, Task Execution and Scheduling, Testing, and more.Web: Servlet Web, Reactive Web, Embedded Container Support, Graceful Shutdown, and more.Data: SQL and NOSQL data access.IO: Caching, Quartz Scheduler, REST clients, Sending email, Spring Web Services, and more.Messaging: JMS, AMQP, Apache Kafka, RSocket, WebSocket, and Spring Integration.

Why 70% to 90% of divorces are initiated by women, why over 50% of divorced women never want to remarry.Latest divorce statistics. More than half of the marriages end up in divorce in America. 70% of divorces are initiated by women on average; 90% of divorces are initiated by women when wives are college educated. Over 50% of divorced women never want to remarry.In the Unified Humanity Science, I will find out, and theoretically, computationally and experimentally verify all the human genetic and cerebral causes of all the human behaviors, including and especially the sexual mating human behaviors.(Early-plugs insertion point. A few seconds of silence in audiovisual.)One of my suppositions in the Unified Humanity Science, that I will theoretically and computationally and experimentally verify, is that humans are benefit-seeking and greedy animals that want to have more in return than the efforts they put in.My conjecture is that for women, and men, sexual mating relationships are benefit-seeking activities with the expectation of high return on investment, and women leave their sexual mating relationships when the effort they put into their sexual mating relationships do not return sufficient benefit and gain in their judgment.How do I prove or disprove, at the human genetic and cerebral levels, that women seek benefit and gain in their sexual mating relationships, and leave their sexual mating relationships when there is no sufficient benefit and gain for them?For precisely pinpointing the human female genetic and cerebral causes of the human female sexual mating behaviors, I will microscopically 3D scan dead human female brains for finding the locations and types of all the female human brain cells and synapses, analyze and determine all the biomolecules in dead human female brains, and computationally model the human female brain operations at the female human brain tissular, cellular, subcellular, molecular, atomic, and subatomic levels.

All class and array types inherit the methods of class Object; the method clone is used to make a duplicate of an object; the method equals defines a notion of object equality, which is based on value, not reference, comparison; the method finalize is run just before an object is destroyed; the method getClass returns the Class object that represents the class of the object; a Class object exists for each reference type, which can be used to discover the fully qualified name of a class, its members, its immediate superclass, and any interfaces that it implements; a class method that is declared synchronized synchronizes on the monitor associated with the Class object of the class; the method hashCode is very useful, together with the method equals, in hashtables such as java.util.HashMap; the methods wait, notify, and notifyAll are used in concurrent programming using threads; the method toString returns a String representation of the object.(Early-plugs insertion point. A few seconds of silence in audiovisual.)Instances of class String represent sequences of Unicode code points. A String object has a constant (unchanging) value. String literals and text blocks are references to instances of class String. The string concatenation operator + implicitly creates a new String object when the result is not a constant expression.Two reference types are the same compile-time type if they are declared in compilation units associated with the same module, and they have the same binary name, and their type arguments, if any, are the same, applying this definition recursively.When two reference types are the same, they are sometimes said to be the same class or the same interface.At run time, several reference types with the same binary name may be loaded simultaneously by different class loaders. These types may or may not represent the same type declaration. Even if two such types do represent the same type declaration, they are considered distinct.Two reference types are the same run-time type if they are both class or both interface types, are defined by the same class loader, and have the same binary name, in which case they are sometimes said to be the same run-time class or the same run-time interface; they are both array types, and their component types are the same run-time type.A type variable is an unqualified identifier used as a type in class, interface, method, and constructor bodies.A type variable is introduced by the declaration of a type parameter of a generic class, interface, method, or constructor.

Historically, empires have waged wars for any combination of three main reasons, which are the expansion and defence of ideologies, the expansion and defence of territorial dominance, and the expansion and defence of access to more resources.The American Empire is no exception: the American Empire has waged wars for the expansion and defence of the American ideologies, the expansion and defence of the American territorial dominance, and the expansion and defence of the American access to more resources.(Early-plugs insertion point. A few seconds of silence in audiovisual.)I'm particularly interested in America's mass expansion into outer space via the nuclear-fusion powered outer space tech in the future; I'll keep working on it.In the past two decades, the Middle East, as well as China, have been in the American military's crosshairs.In this day and age of atomic bombs, there's an enormous difference between a direct all-out no-holds-barred war between nuclear superpowers, and a war involving a non-nuclear-weapon nation or a so-called proxy war; all-out nuclear warfare cannot be done due to the threat and real possibility of humanity going extinct, but limited, non-nuclear warfares can be done; humans don't go to war to exterminate themselves; humans go to war to benefit themselves; human wars in the future will continue to happen within the context of benefiting some parties and parcipants in wars; above all, waging a war is for self-benefit.Since both America and China are nuclear superpowers, and China is increasing its nuclear weapon stock, all out nuclear warfare isn't how a war between America and China will be angled and played, while America and China constantly vye for dominance. China's nuclear intercontinental ballistic missiles can hit the mainland U.S. and vice versa; the all-out nuclear warfare between China and America would mean the loss of billions of human lives, if not the extinction of the entire humanity. Self-extermination is never an aim in a war.For America, a victory in a war with China would yield keeping its dominant position in the world and all the national benefits that come from being the most dominant nation in the world. In a war with China, America is playing a defensive position, whereas China is playing an offensive position for expanding its reach and influence around the world.For America, a victory in a war with a Middle Eastern nation would yield expansion of its national ideologies, national prestige and territorial dominance, and national access to more petroleum.Human benefit is a very complex issue, and wars waged for national benefit often result in unintended consequences. For example, the American invasion of Iraq has helped China economically: In AD 2021, Iraq exported US$23.1 worth of petroleum to China, and US$3.26 worth of petroleum to America. China has economically and politically benefited from the U.S. invasion of Iraq. China's economic rise made wealthy Americans a lot of money, and gave some economic benefits of cheap manufactured goods to the American middle class and poor, while destroying many American manufacturing jobs. There are a lot of complex factors involved in human benefit with multitudes of consequences.How will the rivalry between America and China play out? I don’t think America and China vying for technological, economic, and military supremacy will stop—it's in human nature to seek supremacy in every human level, at individual, couple, family, group, organizational, regional, national, and civilizational human levels.My bet is that the Chinese ruling class knows how to play international politics and power games very well; they've been doing it for over 5,000 years.The Western ruling class also knows how to play international politics and power games very well; they've been doing it since the Ancient Greco-Roman times.To me, it seems that China's main strategy in competing against America is undermining...

A NaN value is used to represent the result of certain invalid operations such as dividing zero by zero. NaN constants of both float and double type are predefined as Float.NaN and Double.NaN.Floating-point operations. The Java programming language provides a number of operators that act on floating-point values.The comparison operators, which result in a value of type boolean: The numerical comparison operators, The numerical equality operators.(Early-plugs insertion point. A few seconds of silence in audiovisual.)The numerical operators, which result in a value of type float or double: The unary plus and minus operators, The multiplicative operators, The additive operators, the prefix and postfix increment operators, the prefix and postfix decrement operators.The conditional operator.The cast operator , which can convert from an floating-point value to a value of any specified numeric type.The string concatenation operator, which, when given a String operand and a floating-point operand, will convert the floating-point operand to a String representing its value in decimal form (without information loss), and then produce a newly created String by concatenating the two strings.Other useful constructors, methods, and constants are predefined in the classes Float, Double, and Math.If at least one of the operands to a binary operator is of floating-point type, then the operation is a floating-point operation, even if the other operand is integral.Any value of a floating-point type may be cast to or from any numeric type. There are no casts between floating-point types and the type boolean.The boolean type and boolean values. The boolean type represents a logical quantity with two possible values, indicated by the literals true and false.The boolean operators are: The relational operators, The logical complement operator, The logical operators, The conditional-and and conditional-or operators, The conditional operator, The string concatenation operator.The string concatenation operator, when given a String operand and a boolean operand, will convert the boolean operand to a String (either "true" or "false"), and then produce a newly created String that is the concatenation of the two strings.Boolean expressions determine the control flow in several kinds of statements: The if statement, The while statement, The do statement, The for statement.A boolean expression also determines which subexpression is evaluated in the conditional ? : operator.
