Kolumbien wird die kommende COP16 zur Biodiversität in Cali dazu benutzen, die Bewahrung der Natur zu einem zentralen Thema der "globalen Umweltagenda" zu machen - auch im Vorfeld der Klima-COPs in Aserbaidschan und Brasilien. Der Guardian hat mit der kolumbianischen Umweltministerin Susana Muhamad gesprochen und berichtet über die Vorbereitungen der Konferenz. https://www.theguardian.com/environment/2024/feb/23/colombia-names-cali-as-host-city-cop16-biodiversity-summit-aoe

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.
Certainly! Let's break down the provided code snippets:
1. What is it and why is it used?
In Mongoose, a schema is a blueprint for defining the structure of documents within a collection. When you define a schema, you can also attach methods to it. These methods become instance methods, meaning they are available on the individual documents (instances) created from that schema.
Instance methods are useful for encapsulating functionality related to a specific document or model instance. They allow you to define custom behavior that can be executed on a specific document. In the given example, the
findSimilarTypes
method is added to instances of theAnimal
model, making it easy to find other animals of the same type.2. Syntax:
Using
methods
object directly in the schema options:javascript const animalSchema = new Schema( { name: String, type: String }, { methods: { findSimilarTypes(cb) { return mongoose.model('Animal').find({ type: this.type }, cb); } } } );
Using
methods
object directly in the schema:javascript animalSchema.methods.findSimilarTypes = function(cb) { return mongoose.model('Animal').find({ type: this.type }, cb); };
Using
Schema.method()
helper:javascript animalSchema.method('findSimilarTypes', function(cb) { return mongoose.model('Animal').find({ type: this.type }, cb); });
3. Explanation in Simple Words with Examples:
Why it's Used:
Imagine you have a collection of animals in your database, and you want to find other animals of the same type. Instead of writing the same logic repeatedly, you can define a method that can be called on each animal instance to find similar types. This helps in keeping your code DRY (Don't Repeat Yourself) and makes it easier to maintain.
Example:
```javascript const mongoose = require('mongoose'); const { Schema } = mongoose;
// Define a schema with a custom instance method const animalSchema = new Schema({ name: String, type: String });
// Add a custom instance method to find similar types animalSchema.methods.findSimilarTypes = function(cb) { return mongoose.model('Animal').find({ type: this.type }, cb); };
// Create the Animal model using the schema const Animal = mongoose.model('Animal', animalSchema);
// Create an instance of Animal const dog = new Animal({ type: 'dog', name: 'Buddy' });
// Use the custom method to find similar types dog.findSimilarTypes((err, similarAnimals) => { console.log(similarAnimals); }); ```
In this example,
findSimilarTypes
is a custom instance method added to theAnimal
schema. When you create an instance of theAnimal
model (e.g., a dog), you can then callfindSimilarTypes
on that instance to find other animals with the same type. The method uses thethis.type
property, which refers to the type of the current animal instance. This allows you to easily reuse the logic for finding similar types across different instances of theAnimal
model.

An important aspect missing in typical flow models is that in order to produce enduringcommitment a goal should correspond to something truly valuable. For example, while the goal ofshooting a maximum number of spaceships in your game of Space Invaders may be clear, it doesnot satisfy any real needs. Therefore, playing games, however enjoyable at the time, if continuedlong enough will eventually leave you with the feeling of having wasted your time. One way gamedesigners try to overcome this limitation is by creating a sense of “epic meaning” (McGonigal,2011), i.e. situating the game action in a narrative context which implies that something truly greator valuable is being achieved (like saving the world from alien invaders).
The epic meaning of "Bend the Curve" is saving civilization, co-creating a future worth living in the next few years, averting disaster.
On a personal level the transformation of the individual also conveys epic meaning.

One solution that fixed this issue with my ISP was that when I went through the first and second line and got in touch with the people that fixed my problem, I asked them if they could give me one of their personal numbers in case the same problem happened again. The problem did occur a couple more times, and I just directly called the same guy.

Tech support works with scripts. Just get to know these scripts by heart and answer all questions from the script you can in one long sentence, before they ask it. Like in "Hi I have a problem with this and that...I have restarted the router, I have checked the cables, the red light is on, the green light is off, not other lights are blinking......etc.etc.etc. That way the person at the other end of the line can just go click-click-click and you'll be 10 steps further in their script in 5 seconds.

More importantly, using a plain email would save lots of time and effort. As a goal-driven-lazy person, that’s a good enough reason to start experimenting.
