Encapsulation refers to the bundling of data with the methods that operate on that data.

The basic classification of a form object is a class that contains writable attributes, validations and logic to persist the attributes to ActiveRecord objects. These forms can also include other side-effects like background job triggers, emails, and push-notifications etc. The simplest way to understand the concept is to think of them as a representation of a controller action where all of the business logic that happens in that controller action is abstracted into a form object.

I take my own definition of the word “community” from educational theorists Etienne and Beverly Wenger: “communities of practice are groups of people who share a concern or a passion for something they do, and learn how to do it better as they interact regularly.” I like this definition because it is so broad while capturing a really specific truth about groups.

Turbolinks is a Single-Page Application Turbolinks doesn't just give you some of the benefits of a single-page app. Turbolinks is a single page app. Think about it: When someone visits your site, you serve them some HTML and Javascript.

Popup - You don't need to deal with these messages right away, yet at some point you will need to take action since these won't go away until explicitly say say you don't want them around anymore.

Popover/Tooltip/Hovercard - These are passive approaches to showing more information. These are used to add simple instructions or explanations or foreshadow what will happen if you click a link.

A pop-up is a modal view that can either take form as a pop-up menu or a pop-up dialog. To my understanding, when we use the word “pop-up”, what we want to express is the pop-up motion effect on the call-out of the UI treatment.

A popover is a transient view that shows on a content screen when a user clicks on a control button or within a defined area.

Validity is a unitary concept. It is the degree to which all the accumulated evidence supports the intended interpretation of test scores for the proposed use. Like the 1999 Standards, this edition refers to types of validity evidence, rather than distinct types of validity. To empha-size this distinction, the treatment that follows does not follow historical nomenclature (i.e., the use of the terms content validity or predictive validity). (

“a test is valid for anything with which it correlates” (p. 429). The idea here was that, if there were a “gold standard” of the con-struct (often, an earlier test), and if scores on the test correlated with that gold standard, the test could be inferred to be a measure of the construct. Note that this is a variety of the “if it walks like a duck and quacks like a duck, it must be a duck” argument.

Validity refers to the degree to which evidence and theory support the interpretations of test scores for proposed uses of tests”

A construct is a theoretical entity hypothesized to account for particular behaviors or characteristics of people. Examples of constructs abound in the social sciences and include creativity, intelligence, various abilities and attitudes, personality characteris-tics, and value systems.

A tooltip is an element containing simple text content describing a particular element. It's hidden until the user desires more information from the element, e.g. before deciding to click a button.

A popover is an interactive HTML tooltip. It can be a dropdown, menu, or any other kind of box that pops out from the normal flow of the document. This type of element contains non-vital functionality and can be hidden behind a click or hover to conserve space.

Both are elements positioned near a "reference" element, and are hidden until they are triggered. They help conserve space by hiding secondary information or functionality behind a hover or click. They are positioned outside the normal flow of the document so when they are triggered, they are overlaid on top of the existing UI without disrupting the flow of content.

In the OS design system, a pop-up menu is used to display a list of mutually exclusive choices.

Chapter 2 Interpretability

Black and white thinking is the tendency to think in extremes: I am a brilliant success, or I am an utter failure. My boyfriend is an angel, or He’s the devil incarnate. This thought pattern, which the American Psychological Association also calls dichotomous or polarized thinking, is considered a cognitive distortion because it keeps us from seeing the world as it often is: complex, nuanced, and full of all the shades in between. An all-or-nothing mindset doesn’t allow us to find the middle ground.

Polarized thinking or black and white thinking is an irrational thinking characterized by the “all or nothing” principle

Sometimes called all-or-nothing, or black and white thinking, this distortion occurs when people habitually think in extremes

A display manager is the component of your Operating system responsible for launching your display server and the login session. This is the reason it is sometimes called the login manager. The layout of the screen that you see while entering your username and password(the greeter), your login session and user authorization are some of the tasks that the display manager performs.

What is a data-originated component? It’s a kind of component that is primarily designed and built for either: displaying, entering, or customizing a given data content itself, rather than focusing on the form it takes. For example Drawer is a non data-originated component, although it may include some. Whereas Table, or Form, or even Feed are good examples of data-originated components.

Final Form makes the assumption that your validation functions are "pure" or "idempotent", i.e. will always return the same result when given the same values.

Distance learning has been defined as “planned learning that normally occurs in a different place from teaching and as a result requires special tech-niques of course design, special instructional techniques, special methods of communication by electronic and other technology, as well as special organi-zational and administrative arrangements” (Moore and Kearsley, 1996, p. 2).

Researchers in the field use the term affordances to refer to oppor-tunities that a technology makes possible related to learning and instruction (Collins et al., 2000)

Self-determination theory posits that behavior is strongly influenced by three universal, innate, psychological needs—autonomy (the urge to control one’s own life), competence (the urge to experience mastery), and psycho-logical relatedness (the urge to interact with, be connected to, and care for others).

Self-efficacy theory (Bandura, 1977), which is incorporated into several models of motivation and learning, posits that the perceptions learners have about their competency or capabilities are critical to accomplishing a task or attaining other goals (Bandura, 1977).

Motivation is a condition that activates and sustains behavior toward a goal

Self-explanationis a strategy in which learners produce explanations of material or of their thought processes while they are reading, answering ques-tions, or solving problems.

Elaborative interrogation is a strategy in which learners are asked, or are prompted to ask themselves, questions that invite deep reasoning, such as why, how, what-if, and what-if not (as opposed to shallow questions such as who, what, when, and where) (Gholson et al., 2009).

The intuition behind POJOs is that a POJO is an object that only contains data, as opposed to methods or internal state. Most JavaScript codebases consider objects created using curly braces {} to be POJOs. However, more strict codebases sometimes create POJOs by calling Object.create(null) to avoid inheriting from the built-in Object class.

Today, racist means not only burning a cross on someone’s lawn or even telling someone to go home, but also what feels unpleasant to someone of a race—as in what I as a person of that race don’t like. It has gone from being mean to someone to, also, what feels mean to me.

So Ocasio-Cortez gets in that the Squad is composed of women of color. But if Pelosi would likely respond the same way to four Jill Steins, then what is the meaning of the reference to race? Is the idea that Pelosi should hold her tongue simply because the Squad members aren’t white? Ocasio-Cortez is here appealing to another 2.0 meaning of racist—that which is offensive, for any reason, to people of a race. The Squad doesn’t like Pelosi’s critique, understandably. But the question is: Is that critique “racist” because four “racial” women don’t agree with it? Here, Ocasio-Cortez and the Squad allude to the subjectified meaning of racist, which can be hard to square with the core meaning of the word (believing that people of a category are inferior).

Mitchum noted that racism “is a system of advantage based on skin color.”
