    1. Remember there are two kinds of variable. Internal Variables and Environment Variables. PATH should be an environment variable.

      In my case, I was trying to debug which asdf not finding asdf, in a minimal shell.

      I had checked bash-5.1$ echo $PATH|grep asdf /home/tyler/.asdf/bin

      but ```

      The PATH environment variable

      env | /bin/grep PATH `` being empty was the key discovery here. Must have forgotten theexport`.

    2. All shells should tell you that your path is the same thing with BOTH of the two commands: # The PATH variable echo "$PATH" # The PATH environment variable env | /bin/grep PATH

    1. I think the answer lies here: Cant see into oneOf or allOf etc. This, I think, is the distinguishing difference between additionalProperties and unevaluatedProperties.
    2. We do not want to change or remove additionalProperties. Providing a clear solution for the above use case will dramatically reduce or eliminate the misunderstandings around additionalProperties.

      annotation meta: may need new tag: - don't want to change or remove existing feature [because...] - solving problem B will reduce misunderstandings around feature A

    1. These callbacks are smart enough to run after the final (outer) transaction* is committed. * Usually, there is one real transaction and nested transactions are implemented through savepoints (see, for example, PostgreSQL).

      important qualification: the outer transaction, the (only) real transaction

    1. Object hierarchies are very different from relational hierarchies. Relational hierarchies focus on data and its relationships, whereas objects manage not only data, but also their identity and the behavior centered around that data.

    1. Fundamentally, I think promise rejection is substantially different than "throwing" under normal synchronous flow.
    2. but has a critical difference: the expression console.log("before 2"); does not and cannot depend on the resolved value result. The throw propagates through all chained promises, and when it stops, there is no remaining undefined behavior! No piece of code is left in an unclear state, and therefore there is no reason to crash.
    1. Meaning if you have your own roll-your-own login process and never use HTTP Authentication, 403 is always the proper response and 401 should never be used.
    2. So, for authorization I use the 403 Forbidden response. It’s permanent, it’s tied to my application logic, and it’s a more concrete response than a 401. Receiving a 403 response is the server telling you, “I’m sorry. I know who you are–I believe who you say you are–but you just don’t have permission to access this resource. Maybe if you ask the system administrator nicely, you’ll get permission. But please don’t bother me again until your predicament changes.”

    1. Inflections go the other way around.In classic mode, given a missing constant Rails underscores its name and performs a file lookup. On the other hand, zeitwerk mode checks first the file system, and camelizes file names to know the constant those files are expected to define.While in common names these operations match, if acronyms or custom inflection rules are configured, they may not. For example, by default "HTMLParser".underscore is "html_parser", and "html_parser".camelize is "HtmlParser".

    1. 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.

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

      due to echo adding the spaces, not due to the spaces already being present

      Tag: not so much:

      whose responsibility is it? but more: what handles this / where does it come from? (how exactly should I word it?)

    1. 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.

      They shouldn't use synonyms for this (modified = changed).

      It would be clearer if the word that differed between the terms indicated what changed:

      • "content modified" time (cctime)?
      • "meta modified" time (cmtime)?
    1. 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.

    1. 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.
    1. Dictionary writers list polysemes under the same entry; homonyms are defined separately.

      This describes how you can tell which one it is by looking at the dictionary entry.

    2. 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.
    1. 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).
    2. 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.
    3. The selector [value=""] tests whether the element has the value attribute in markup and has the empty string as its value.

    1. 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.

      Failed type checks generate run-time errors. So it's up to the develop to fix these, permanently, since the user can't (99% of time) do anything to fix these.

      Failed validations add errors to interaction.errors object. These are for the user to fix.

    1. 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

    1. The delete operator does not directly free memory, and it differs from simply assigning the value of null or undefined to a property, in that the property itself is removed from the object.
    1. this in particular comes from the addressee

      I think the ruling's main point/distinction here is that while submitting a form might be getting consent from the addressee (the person submitting form might be the addressee, if they own the e-mail address they entered), but we can't know that for sure until they confirm by clicking a link in the e-mail.

      Only then do we know for sure that the actor submitting the form was the addressee and that the consent ostensibly received via the form was in fact from the addressee. But it could otherwise be the case that they entered someone else's address, and you can't give consent on behalf of someone else!

    1. This module should not be used in other npm modules since it modifies the default require behavior! It is designed to be used for development of final projects i.e. web-sites, applications etc.
    1. The resolving process is basically simple and distinguishes between three variants: absolute path: require("/home/me/file") relative path: require("../src/file") or require("./file") module path: require("module/lib/file")

      Very important distinction

    1. Using as * adds a module to the root namespace, so no prefix is required, but those members are still locally scoped to the current document.


      • root namespace (so no prefix is required), but
      • locally scoped (to the current document)

    1. Your problem is that you were returning the rejected loginDaoCall, not the promise where the error was already handled. loginApi.login(user, password) did indeed return a rejected promise, and even while that was handled in another branch, the promise returned by the further .then() does also get rejected and was not handled.

    1. Free software thus differs from: proprietary software, such as Microsoft Office, Google Docs, Sheets, and Slides or iWork from Apple. Users cannot study, change, and share their source code. freeware, which is a category of proprietary software that does not require payment for basic use.

    1. In a basic configuration, GitLab runs a pipeline each time changes are pushed to a branch. If you want the pipeline to run jobs only when merge requests are created or updated, you can use pipelines for merge requests.
    1. In the context of first-order logic, a distinction is maintained between logical validities, sentences that are true in every model, and tautologies, which are a proper subset of the first-order logical validities. In the context of propositional logic, these two terms coincide.

      A distinction is made between the kind of logic (first-order logic) where this other distinction exists and propositional logic, where the distinction doesn't exist (the two terms coincide in that context).

    1. It may be the case that several sufficient conditions, when taken together, constitute a single necessary condition (i.e., individually sufficient and jointly necessary)
    1. However, please note the following: it will depend on how those subdomains are defined. Are they just subsections of a project that belongs together like help.example.com or blog.example.com (and many other possible arrangements that are part of one and the same setup)? In such a case, using the same policy is appropriate. Problems arise when completely different projects which have little to do with one another and whose data collection practices also differ so significantly that they require different privacy policies.

    1. A single consent form is useful when consent is requested for a single purpose. Here: analytics

      This seems like an important distinction:  Probably (?) you can only use a simple Agree/Disagree consent request if you only have a single purpose/category that you are obtaining consent for.

      As soon as your site has multiple categories to need consent, then you must allow individual consent/refusal of consent for each individual category/purpose.

      This is alluded to just a little bit further on:

      Consent should also be granular; users must be allowed to selectively decide what types of tracking, analytics and other activities their data can be used for.
