to your point for 00:13:46 every problem there's going to be a solution and AI is going to have it and then for every solution for that there's going to be a new problem

Instance methods Instances of Models are documents. Documents have many of their own built-in instance methods. We may also define our own custom document instance methods. // define a schema const animalSchema = new Schema({ name: String, type: String }, { // Assign a function to the "methods" object of our animalSchema through schema options. // By following this approach, there is no need to create a separate TS type to define the type of the instance functions. methods: { findSimilarTypes(cb) { return mongoose.model('Animal').find({ type: this.type }, cb); } } }); // Or, assign a function to the "methods" object of our animalSchema animalSchema.methods.findSimilarTypes = function(cb) { return mongoose.model('Animal').find({ type: this.type }, cb); }; Now all of our animal instances have a findSimilarTypes method available to them. const Animal = mongoose.model('Animal', animalSchema); const dog = new Animal({ type: 'dog' }); dog.findSimilarTypes((err, dogs) => { console.log(dogs); // woof }); Overwriting a default mongoose document method may lead to unpredictable results. See this for more details. The example above uses the Schema.methods object directly to save an instance method. You can also use the Schema.method() helper as described here. Do not declare methods using ES6 arrow functions (=>). Arrow functions explicitly prevent binding this, so your method will not have access to the document and the above examples will not work.

This occurs for the child processes, where the entry is still needed to allow the parent process to read its child's exit status: once the exit status is read via the wait system call, the zombie's entry is removed from the process table and it is said to be "reaped".

This means that when considering the "unevaluatedProperties": false in the root schema, "wheels" has not been evaluated, so unevaluatedProperties applies to it, and therefore validation fails because the false subschema fails by definition against any instance.

a benchmark tells you how slow your code is ("it took 20 seconds to do X Y Z") and a profiler tells you why it's slow ("35% of that time was spent doing compression").

Think the mere existence of a file is effectively like writing a require call for them, which is executed on demand (autoload) or upfront (eager load).

FORBIDDEN: Status code (403) indicating the server understood the request but refused to fulfill it. User/agent known by the server but has insufficient credentials. Repeating request will not work, unless credentials changed, which is very unlikely in a short time span.

There's a problem with 401 Unauthorized, the HTTP status code for authentication errors. And that’s just it: it’s for authentication, not authorization. Receiving a 401 response is the server telling you, “you aren’t authenticated–either not authenticated at all or authenticated incorrectly–but please reauthenticate and try again.” To help you out, it will always include a WWW-Authenticate header that describes how to authenticate.

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.”

UNAUTHORIZED: Status code (401) indicating that the request requires authentication, usually this means user needs to be logged-in (session). User/agent unknown by the server. Can repeat with other credentials. NOTE: This is confusing as this should have been named 'unauthenticated' instead of 'unauthorized'.

+----------------------- | RESOURCE EXISTS ? (if private it is often checked AFTER auth check) +----------------------- | | NO | v YES v +----------------------- 404 | IS LOGGED-IN ? (authenticated, aka user session) or +----------------------- 401 | | 403 NO | | YES 3xx v v 401 +----------------------- (404 no reveal) | CAN ACCESS RESOURCE ? (permission, authorized, ...) or +----------------------- redirect | | to login NO | | YES | | v v 403 OK 200, redirect, ... (or 404: no reveal) (or 404: resource does not exist if private) (or 3xx: redirection)

When you initially logon with OAuth2, you will be redirect to Google’s sign-in page,. Once you have signed in, Google issues you a special OAuth2 token which is saved in Thunderbird and can be seen in the same place as passwords. So when you next logon to gmail, it is using that unique OAuth ID instead of password.

In your Svelte component, you can then use your store with the special $ prefix syntax, to access the value of the store ('cause the temperature variable is a reference to the store itself, it's just a mean to our end, the result we need is the value):

Stores are essentially some kind of simplified streams (or Observable as they're called in ES), that is they represent a value over time.

Stores are the idiomatic Svelte way when you need to import "reactivity" from your normal JS sources.

function strictIsDog<T extends Dog extends T ? unknown : never>( // like <T super Dog> candidate: Dog | T // if Dog extends T then Dog | T is T ): candidate is Dog { // compiler recognizes that Dog | T can narrow to T return "bark" in candidate; } if (strictIsDog(animal)) {} // okay if (strictIsDog(dog)) {} // okay if (strictIsDog(mixed)) {} // okay if (strictIsDog(cat)) {} // error! // ~~~ <-- Cat is not assignable to Dog

Adding to the accepted answer, if you happen to need to use a type guard against a mixin, you'll get this error too, since the is operator doesn't behave as an implements would.

const isValidMethodForHandler = <T extends { [i: string]: any }>(handler: T) => ( method: string ): method is Extract<keyof T, string> => Object.keys(handler).indexOf(method) !== -1;

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.

Intuitively, a subcategory of C is a category obtained from C by "removing" some of its objects and arrows.

Semantically correct usage of elements means that you use them for what they are meant to be used for.

It means that you're calling something what it actually is.

A Monad wraps a value or a computation with a particular context. A monad must define both a means of wrapping normal values in the context, and a way of combining computations within the context.

The shell process itself is in yet another process group all of its own and so doesn't receive the signal when one of those process groups is in the foreground. It's that simple.

That's covered by "they must differ only by #where"

All those names of things - topology, complex analysis, and differential geometry - might not sound like much to you now, but you'll soon learn that they're really just describing the shapes of things in our Universe, and the way those shapes change in time and space are explained by things like calculus and chaos theory.

Simple answer: If you need the interface in in another module.

So let's say we pull down evil/foo which is FROM ubuntu followed by RUN apt-get update except with a small surprise included in the image. Subsequent builds using those same commands will be compromised.

Not all application state belongs inside your application's component hierarchy. Sometimes, you'll have values that need to be accessed by multiple unrelated components, or by a regular JavaScript module.

A store is simply an object with a subscribe method that allows interested parties to be notified whenever the store value changes. In App.svelte, count is a store, and we're setting count_value in the count.subscribe callback.

Just like elements can have children... <div> <p>I'm a child of the div</p> </div>...so can components. Before a component can accept children, though, it needs to know where to put them. We do this with the <slot> element.

Escaping is a subset of encoding, where not all characters need to be encoded. Only some characters are encoded (by using an escape character).

A programming language is Turing complete if you can implement any possible algorithm with it.

Any variable referenced on the lines marked with $: is marked as a dependency of the derived variable.

setContext must be called synchronously during component initialization. That is, from the root of the <script> tag

To make this “if you install me, you better also install X, Y, and Z!” problem easier, peerDependencies was introduced.
