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.

Storytelling Will Save the EarthEmotional resonance, not cold statistics, will bring home the scale of the climate crisis—and the need for action.

We know the information. But information is not changing our minds. Most people make decisions on the basis of feelings, including the most important decisions in life – what football team you support, who you marry, which house you live in. That is how we make choices.”  “Thought is at the basis of our feelings, and before we have ideas we have feelings that lead to those ideas. So how do we change minds? A change in feelings changes minds.”

Now picture Timothy, who lives with his grandchildren in Walande Island, a small dot of land off the east coast of South Malaita Island, part of the Solomon Islands. Since 2002, the 1,200 inhabitants of Walande have abandoned their homes and moved away from the island. Only one house remains: Timothy’s. When his former neighbors are asked about Timothy’s motives they shrug indifferently. “He’s stubborn,” one says. “He won’t listen to us,” says another. Every morning his four young grandchildren take the canoe to the mainland, where they go to school, while Timothy spends the day adding rocks to the wall around his house, trying to hold off the water for a bit longer. “If I move to the mainland, I can’t see anything through the trees. I won’t even see the water. I want to have this spot where I can look around me. Because I’m part of this place,” he says. His is a story that powerfully conveys the loneliness and loss that 1.1 degrees of anthropogenic warming is already causing. 

What tabs would be particularly useful for is new music discovery, like an album you’ve been wanting to get around to hearing but haven’t yet had the time. I bump into this problem quite a bit. Adding a new album to my “Liked” songs on Spotify shuffles it in with all of my favorite stuff, and decluttering that playlist later is a hassle. Making a new album a playlist almost assures that it’ll be forgotten about. My decrepit, goldfish memory doesn’t have the space to remember to return to a playlist of an album two weeks later. As my colleague Victoria notes, she’s always “forgetting what I’m supposed to listen to next.” You know what would help with that? Tabs.

For every mile we don't drive, our air gets a little bit cleaner. There are many ways to drive less- walking, biking, taking transit, telecommuting, carpooling, and more. Driving less can also save you money and improve your emotional and physical health. Working from home has been gaining popularity and may offer other benefits such as improved productivity.

Save Work On Focus Lost This feature works best in combo with infinite undo. The idea here is that everytime you leave your Vim window, all your open files are automatically saved. I find this to be extremely helpful, for example when I’m working on a laptop and continuously run unit tests in terminal. My laptop is 13'' so I prefer to run Vim full screen and with this feature, I don’t have to explicitly save my source code file; I just cmd+tab to the terminal, Vim saves the file for me and my unit tests watcher re-runs the suite. If you save unwanted changes by accident you can easily remedy that with undo. To turn autosaving on, add: :au FocusLost * silent! wa to your .vimrc. The silent! flag prevents Vim from complaining when you have open unititled buffers (see this article for details).
