Note the difference between pace and cadence. Pace is 1/speed in (eg. min/km) whereas cadence refers to steps/minute

The difference is that this happens in the email client, not at the subscription step. Why is this a big deal? Because, even though they just subscribed to your email, there’s a chance your email won’t get a thumbs up.

The use of U+212B 'Angstrom sign', which was encoded due to round-trip mapping compatibility with an East-Asian character encoding, is discouraged, and the preferred representation is U+00C5 'capital letter A with ring above', which has the same glyph.

It should be defined inline. If you are using the img tag, that image should have semantic value to the content, which is why the alt attribute is required for validation. If the image is to be part of the layout or template, you should use a tag other than the img tag and assign the image as a CSS background to the element. In this case, the image has no semantic meaning and therefore doesn't require the alt attribute. I'm fairly certain that most screen readers would not even know that a CSS image exists.

Ah yes, excactly the right answer. Img tags are for information, css backgrounds are for layout.

use the width (and the height) attribute....to identify the intrinsic height of the image file, not to specify the desired layout size

Historical negationism,[1][2] also called denialism, is falsification[3][4] or distortion of the historical record. It should not be conflated with historical revisionism, a broader term that extends to newly evidenced, fairly reasoned academic reinterpretations of history.

Socrates' dictum may be wise, but I think there's a world of difference between OP's acknowledgement that the amount of things one doesn't know is indeterminate, and Socrates' assertion that, for him, everything falls into that category.

Dry humor is a delivery technique. As such, it shouldn't be confused with specific types of humor or with sarcasm. Sarcasm is delivered without humor because it's generally not funny but intended to mock or convey contempt. Dry humor pertains to something funny.

What is the difference between “wry” and “dry” humor?

Operating systems implement a command-line interface in a shell for interactive access to operating system functions or services.

If no file is detected (in case, it's being run as part of a script or the command is being piped)

STREAMS originated in Version 8 Research Unix, as Streams (not capitalized).

The virtual terminal process resides in kernel space (called the console).It reads from the "tty", say the output from the "ls" process and renders the text. It interacts with the VGA driver to do so.

The (virtual) terminal (not the "tty") plays a central role here

Although echo "$@" prints the arguments with spaces in between, that's due to echo: it prints its arguments with spaces as separators.

Unfortunately, unlike what is described in SWdream solution, --ignore-missing-args has no impact on vanished files. It will simply ignore source arguments that doesn't exist.

You can create a separate grassland area (mountain in between) but you can NOT create a separate landmass (water in between).

A modified timestamp signifies the last time the contents of a file were modified. A program or process either edited or manipulated the file. “Modified” means something inside the file was amended or deleted, or new data was added. Changed timestamps aren’t referring to changes made to the contents of a file. Rather, it’s the time at which the metadata related to the file was changed. File permission changes, for example, will update the changed timestamp.

It's simple really ... put tests into a shared example that you want multiple things to conform to. Put code into a shared context that you need to include in multiple tests.

shared_contexts is any setup code that you can use to prepare a test case . This allows you to include test helper methods or prepare for the tests to run.

It might be better to think of it this way: with the shape-outside property we’re changing the relationship of other elements around an element, not the geometry of the element itself.

CSS-generated content is not included in the DOM. Because of this, it will not be represented in the accessibility tree and certain assistive technology/browser combinations will not announce it. If the content conveys information that is critical to understanding the page's purpose, it is better to include it in the main document.

Requirement #2 contains an unwarranted assumption. The body needs to flow not around the sidebar, but around the sidebar's position. That may seem like splitting hairs, but it isn't -- because what if there were something floated where we want to put the sidebar? The body would flow around that space. If we could put the sidebar in that same location, we'd have a solution.

In my opinion, the W3C definition is unnecessarily confusing and restrictive. The dictionary definition of aside is "a temporary departure from a main theme or topic", and the spec should just stick to that, rather than introducing subtle distinctions.

I believe the accepted answer is not quite correct. According to the HTML5 working draft, the <aside> element can be used to mark up side notes in certain, but not all cases:

a remark or passage that departs from the theme of a discourse : digression The speaker inserted some often amusing parentheses during his speech.

an amplifying (see amplify sense 1) or explanatory word, phrase, or sentence inserted in a passage from which it is usually set off by punctuation explained further in a parenthesis

Parking Attendant is a glorified app game that somehow landed into the Steam Store

I like this approach more because I can scan the code that renders the Box component and easily spot that it takes two children. If the Box took any props, they'd be within the opening <Box> tag, and they would be distinct from any children props.

Lexical (semiotics) or content word, words referring to things, as opposed to having only grammatical meaning

Not to be confused with tree (graph theory), a specific type of mathematical object.

Not to be confused with trie, a specific type of tree data structure. Not to be confused with tree (graph theory), a specific type of mathematical object.

Some types exist as descriptions of objects, but not as tangible physical objects. One can show someone a particular bicycle, but cannot show someone, explicitly, the type "bicycle", as in "the bicycle is popular."

Property types (e.g. "height in metres" or "thorny") are often understood ontologically as concepts. Property instances (e.g. height = 1.74) are sometimes understood as measured values, and sometimes understood as sensations or observations of reality.

The words type, concept, property, quality, feature and attribute (all used in describing things) tend to be used with different verbs. E.g. Suppose a rose bush is defined as a plant that is "thorny", "flowering" and "bushy". You might say a rose bush instantiates these three types, or embodies these three concepts, or exhibits these three properties, or possesses these three qualities, features or attributes.

The distinction in computer programming between classes and objects is related, though in this context, "class" sometimes refers to a set of objects (with class-level attribute or operations) rather than a description of an object in the set, as "type" would.

The distinction is important in disciplines such as logic, linguistics, metalogic, typography, and computer programming.

The sentence "they drive the same car" is ambiguous. Do they drive the same type of car (the same model) or the same instance of a car type (a single vehicle)?

In the simple biology example, dog is a hypernym and Fido is one of its hyponyms. A word can be both a hyponym and a hypernym. For example, dog is a hyponym of mammal and also a hypernym of Fido.

words that are examples of categories are hyponyms

Two of the predominant types of relationships in knowledge-representation systems are predication and the universally quantified conditional.

Taxonomy is different from meronomy, which is dealing with the categorisation of parts of a whole.

The is-a relationship may also be contrasted with the instance-of relationship between objects (instances) and types (classes): see Type–token distinction.

While propositional logic can only express facts, autoepistemic logic can express knowledge and lack of knowledge about facts.

A predicate whose quantifiers all apply to individual elements, and not to sets or predicates, is called a first-order predicate.

a class is an implementation‍—‌a concrete data structure and collection of subroutines‍—‌while a type is an interface

Elin K. Jacob found that classification and categorization are different processes

Categorization is grounded in the features that distinguish the category's members from nonmembers.

semantic domain or semantic field

Sometimes lexicography is considered to be a part or a branch of lexicology, but properly speaking, only lexicologists who write dictionaries are lexicographers.

Some consider this a distinction of theory vs. practice.

An allied science to lexicology is lexicography, which also studies words, but primarily in relation with dictionaries – it is concerned with the inclusion of words in dictionaries and from that perspective with the whole lexicon

Not to be confused with lexicography.

It's not really about avoiding that association; in many situations only one or the other is correct and you can't substitute willy-nilly

it has more to do with semantics than euphony

A hyponym refers to a type. A meronym refers to a part. For example, a hyponym of tree is pine tree or oak tree (a type of tree), but a meronym of tree is bark or leaf (a part of tree).

Synonymy requires the sharing of a sememe or seme, but the semantic field is a larger area surrounding those.

A general and intuitive description is that words in a semantic field are not necessarily synonymous, but are all used to talk about the same general phenomenon.

a stative verb is one that describes a state of being, in contrast to a dynamic verb, which describes an action

Semantics: deals with the formal properties and interrelation of signs and symbols, without regard to meaning.

However, if the distinctions between the two concepts appear to be superficial, intentional conflation may be desirable for the sake of conciseness and recall

Dictionary writers list polysemes under the same entry; homonyms are defined separately.

Polysemy is thus distinct from homonymy—or homophony—which is an accidental similarity between two words (such as bear the animal, and the verb to bear); while homonymy is often a mere linguistic coincidence, polysemy is not.

Does running nsgcepa by itself not then run the .desktop which in turn runs that command? Probably not. Desktop launchers are used by e.g. application menus. Executables are the binaries or scripts that can be run by desktop launchers. You can also run executables directly from a command line.

xdg-open should do the same thing - actually, it will call gnome-open, or kde-open, or whatever, depending on your desktop environment. Thus it's more portable.

Poetry is more than end rhymes

Why separate out red tests from green tests? Because my green tests serve a fundamentally different purpose. They are there to act as a living specification, validating that the behaviors work as expected. Regardless of whether they are implemented in a unit testing framework or an acceptance testing framework, they are in essence acceptance tests because they’re based upon validating behaviors or acceptance criteria rather than implementation details.

When I refactor my code, I expect that none of my green tests will break. If red tests break then that’s okay because remember, my red tests can be implementation dependent and when I change an implementation it may cause some red tests to break. But it shouldn’t break any green tests. I find that this is a valuable distinction.

I am a big advocate of having a complete test base and even erring on the side of caution when it comes to quality engineering and software validation but that is not what we’re talking about here. What we’re talking about here are the tests that we write when we’re doing test-first development and I’m proposing that writing those tests from the perspective of specifying the behaviors that we want to create is a highly valuable way of writing tests because it drives us to think at the right level of abstraction for creating behavioral tests and that allow us the freedom to refactor our code without breaking it.

this only applies to end products which are actually deployed. For my modules, I try to keep dependency version ranges at defaults, and recommend others do the same. All this pinning and packing is really the responsibility of the last user in the chain, and from experience, you will make their life significantly more difficult if you pin your own module dependencies.

The "Pluridisciplinary" or "multidisciplinarity" level The genuine cross-disciplinary level: "interdisciplinarity" The discipline-forming level "transdisciplinarity"

They reduce the distinction between a “core module” and a “plugin”

ECMAScript is a programming language itself, specified in the document ECMA-262. In other words, ECMA-262 is the specification of the programming language ECMAScript. JavaScript is an implementation of ECMAScript which conforms to the ECMAScript specification. JavaScript implementations can also provide additional features not described in the specification.

The ECMAScript standard does not include any input/output (I/O), such as networking, storage, or graphics facilities. In practice, the web browser or other runtime system provides JavaScript APIs for I/O.

I think that over time the distinction is lost. My math teacher, 35 years ago stated "formulas are used in chemistry, in math we have equations". To this day, the word 'formula' in math seems wrong, but I'd accept it's used commonly.

An equation is meant to be solved, that is, there are some unknowns. A formula is meant to be evaluated, that is, you replace all variables in it with values and get the value of the formula.

The key idea is that the equation captures not just the ingredients of the formula, but also the relationship between the different ingredients.

An equation is any expression with an equals sign, so your example is by definition an equation. Equations appear frequently in mathematics because mathematicians love to use equal signs. A formula is a set of instructions for creating a desired result. Non-mathematical examples include such things as chemical formulas (two H and one O make H2O), or the formula for Coca-Cola (which is just a list of ingredients). You can argue that these examples are not equations, in the sense that hydrogen and oxygen are not "equal" to water, yet you can use them to make water.

The :empty selector refers only to child nodes, not input values. [value=""] does work; but only for the initial state. This is because a node's value attribute (that CSS sees), is not the same as the node's value property (Changed by the user or DOM javascript, and submitted as form data).

Generally, CSS selectors refer to markup or, in some cases, to element properties as set with scripting (client-side JavaScript), rather than user actions. For example, :empty matches element with empty content in markup; all input elements are unavoidably empty in this sense. The selector [value=""] tests whether the element has the value attribute in markup and has the empty string as its value. And :checked and :indeterminate are similar things. They are not affected by actual user input.

The selector [value=""] tests whether the element has the value attribute in markup and has the empty string as its value.

You’d think :empty would be it, but it’s not. That’s for matching things like <p></p>… container elements with nothing inside them. Inputs are no-content elements already.

Does there exist a Unicode new-line, which I could copy-paste? (PLEASE NOTE, I DON'T ASK ABOUT THE CODE, like U+000D or whatever is considered as new line. I want the "copyable" output, like the above space (which I have put above in brackets and can be copied). So, if there is, please paste it in your answer, so I could copy it, like you copy the unicode space above from brackets.

markdown-it is the result of the decision of the authors who contributed to 99% of the Remarkable code to move to a project with the same authorship but new leadership (Vitaly and Alex). It's not a fork.

What's an object (i.e. not a primitive)?

One way the restaurant achieves this is by refusing to do delivery. You can order breakfast and lunch at the window; dinner has to be arranged in advance, by email. Either way, your first encounter is with one of Winner’s employees or Mr. Eddy himself, not a third-party app. Apps may be convenient, but I’ve never used an app that remembered that a member of my household has a life-threatening food allergy, as a Winner employee did the second time I placed a dinner order. Nor have I had one offer to set aside a few loaves of bread, which typically sell out by late afternoon.

The flow pipetree is a mix of the Either monad and “Railway-oriented programming”, but not entirely the same.

in functional programming, the terms "conditional expression" or "conditional construct" are preferred, because these terms all have distinct meanings

there are two key elements to an anti-pattern that distinguish it from a bad habit, bad practice, or bad idea

This is done to avoid confusion by differentiating between cases where a variable carries a defined value and those where it does not.

Operations are often confused as god objects that do “everything”. However, operations are nothing but orchestrators.

One of the most difficult transitions for leaders to make is the shift from doing to leading.

"Open access" refers to toll-free or gratis access to content

In this continuum of community participation covered by CBD, new-generation CDD projects are located at the extreme right

However, CDD projects fit on the empowerment end of CBD by actively engaging beneficiaries in the design, management and implementation of projects

A distinction may also be made between standard (peer-to-peer) content and premium-charged content.

The LGPL allows users to use and integrate LGPL software components into their own software without being required to release the source code of their own software components. However, if users modify LGPL software components (“derivative work”), they are required to make the modified software component available under the same LGPL license. To avoid the latter with TRB, users have to comply with para. 5 LGPLv2.1: A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a “work that uses the Library”. Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. In other words: if you use the TRB libraries in your commercial applications or Open-Source projects, you’re not creating a derivative work of Trailblazer. Your software can be distributed under any terms.

non-interactive shells (actually when job control is not enabled)

You might be confused because echo is both a shell built-in and a separate command.

When you run this interaction, two things will happen. First ActiveInteraction will type check your inputs. Then ActiveModel will validate them. If both of those are happy, it will be executed.

The problem is that you what you want is actually not de-structuring at all. You’re trying to go from 'arg1', { hash2: 'bar', hash3: 'baz' }, { hash1: 'foo' } (remember that 'arg1', foo: 'bar' is just shorthand for 'arg1', { foo: 'bar' }) to 'arg1', { hash1: 'foo', hash2: 'bar', hash3: 'baz' } which is, by definition, merging (note how the surrounding structure—the hash—is still there). Whereas de-structuring goes from 'arg1', [1, 2, 3] to 'arg1', 1, 2, 3

The term encapsulation is often used interchangeably with information hiding. Not all agree on the distinctions between the two though; one may think of information hiding as being the principle and encapsulation being the technique. A software module hides information by encapsulating the information into a module or other construct which presents an interface.

Does that make it so? Not for me. Were it simply a matter of words, I wouldn't write another word on the matter. But there are two distinct concepts behind these terms, concepts engendered separately and best understood separately.

The more important point comes from a program design perspective. Here, "programming to an interface" means focusing your design on what the code is doing, not how it does it. This is a vital distinction that pushes your design towards correctness and flexibility.

Remix occurs when the original meme is altered in some way, while mimicry occurs when the meme is recreated in a different fashion to the original.

a direct specific meaning as distinct from an implied or associated idea

The word home, for instance, has a denotation of “the place (such as a house or apartment) where a person lives,” but it may additionally have many connotations (such as “warmth,” “security,” or “childhood”) for some people.

While each of these two words has several possible meanings, they are notably distinct from each other in all senses. Denotation is concerned with explicit meaning, and connotation tends to be concerned with implicit meaning.

I agree that validation is a process that determines the property of validity of a certain object

Notice that you’re not naming lines with this syntax, just areas.

Flexbox is for one dimensional layout (row or column). CSS grid is for two dimensional layout.

Owning a blog or website involves two separate pieces, your domain and your host.

It’s kind of like putting a SIM card in a cell phone – the SIM card tells that phone, “Hey, you work with this particular phone number now.” Just like you can switch out a phone’s SIM card and make the phone work with a different phone number, your domain can be set to work with a different web hosting service.

First, the frame and frameset elements are not deprecated in HTML5, they're obsolete (i.e., they've been removed entirely).

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.

This command should not be confused with the reload command.

Taglines are more often next to the company's logo on official advertisements, and are dedicated more specifically to brand awareness than slogans. Slogans carry a brand's values and promises as the company grows and evolves, and can be promoted under an overarching company tagline.

Although both "slogan" and "tagline" tend to be used interchangeably, they actually serve two different purposes. 

What’s the difference between an ad and your recommendation?

It’s easy to think of 1fr as being “one part of the space in the grid container” when it is really one part of the space left over.

And since auto is entirely based on content, we can say it is “indefinitely” sized, its dimensions flex. If we were to put an explicit width on the column, like 50% or 400px, then we would say it is “definitely” sized.

It’s true that the auto value would do the same, but auto isn’t quite as robust since it’s size is based on the content inside.

While it is easy to imagine that all iterators could be expressed as arrays, this is not true. Arrays must be allocated in their entirety, but iterators are consumed only as necessary. Because of this, iterators can express sequences of unlimited size, such as the range of integers between 0 and Infinity.

Note: your arrow must be an HTMLElement (not an SVGElement). To use an SVG arrow, wrap it in a <div> tag with the data-popper-arrow attribute.
