Start writing your own Typescript Method Decorators

What is a Decorator?

It is a structural design pattern that lets you attach new behaviors to objects by placing these objects inside special wrapper objects that contain the behaviors (reference).

When we are using Typescript Method Decorators, they are higher-order functions that help us change method behavior or do something with the arguments.

Typescript method decorator definition: method decorator can be used to observe, modify, or replace a method definition (reference)

Now, let’s see how we can define a simple method decorator.

Setup

In order to run the Typescript code, we need to compile them using the Typescript compiler.

We need a tsconfig.json file :

We have to enable the experimentalDecorators. Also, the target should not be less than ES5.

If you do not want to use a tsconfig file you can pass these options directly:

tsc --experimentalDecorators // If you installed tsc globaly
npx tsc --experimentalDecorators // If you installed tsc in your current directory

Now by running tsc in the current directory, the typescript files will compile to javascript files and we can run them using Node.

What You Can Learn about Setting from Classic Sitcoms

Giving your novel a strong sense of place is vital to doing your part to engage the readers without confusing or frustrating them. Setting is a big part of this (though not the whole enchilada — there is also social context and historic period), and I often find writing students and consulting clients erring on one of two extremes.

**Either: **Every scene is set in a different, elaborately-described place from the last. This leads to confusion (and possibly exhaustion and impatience) for the reader, because they have no sense of what they need to actually pay attention to for later and what’s just…there. Are the details of that forest in chapter 2 important? Will I ever be back in this castle again? Is there a reason for this character to be in this particular room versus the one she was in the last time I saw her? Who knows!

Or: There are few or no clues at all as to where the characters are in a scene. What’s in the room? Are they even in a room? Are there other people in th — ope, yes, there are, someone just materialized, what is happening? This all leads to the dreaded “brains in jars” syndrome. That is, characters are only their thoughts and words, with no grounding in the space-time continuum. No one seems to be in a place, in a body, at a time of day.

Everything aspect of writing a novel comes with its difficulties, and there are a lot of moving pieces to manage and deploy in the right balance. When you’re a newer writer, especially, there’s something to be said for keeping things simple until you have a handle on how to manage the arc and scope of a novel-length work. And whether you tend to overdo settings or underdo them, you can learn something from TV, especially classic sitcoms.

Your basic “live studio audience” sitcoms are performed and filmed on sets built inside studios vs. on location. This helps keep production expenses in check and helps the viewer feel at home — there’s a reliable and familiar container to hold the story of any given episode. The writers on the show don’t have to reinvent the wheel with every script.

Often, a show will have no more than two or three basic sets that are used episode to episode, and then a few other easily-understood sets (characters’ workplaces, restaurants, streets scenes) are also used regularly but not every episode.

How to start an electric scooter facility/fleet in a university campus/IT park

Are you leading an organization that has a large campus, e.g., a large university? You are probably thinking of introducing an electric scooter/bicycle fleet on the campus, and why wouldn’t you?

Introducing micro-mobility in your campus with the help of such a fleet would help the people on the campus significantly. People would save money since they don’t need to use a car for a short distance. Your campus will see a drastic reduction in congestion, moreover, its carbon footprint will reduce.

Micro-mobility is relatively new though and you would need help. You would need to select an appropriate fleet of vehicles. The people on your campus would need to find electric scooters or electric bikes for commuting, and you need to provide a solution for this.

To be more specific, you need a short-term electric bike rental app. With such an app, you will be able to easily offer micro-mobility to the people on the campus. We at Devathon have built Autorent exactly for this.

What does Autorent do and how can it help you? How does it enable you to introduce micro-mobility on your campus? We explain these in this article, however, we will touch upon a few basics first.

Micro-mobility: What it is

You are probably thinking about micro-mobility relatively recently, aren’t you? A few relevant insights about it could help you to better appreciate its importance.

Micro-mobility is a new trend in transportation, and it uses vehicles that are considerably smaller than cars. Electric scooters (e-scooters) and electric bikes (e-bikes) are the most popular forms of micro-mobility, however, there are also e-unicycles and e-skateboards.

You might have already seen e-scooters, which are kick scooters that come with a motor. Thanks to its motor, an e-scooter can achieve a speed of up to 20 km/h. On the other hand, e-bikes are popular in China and Japan, and they come with a motor, and you can reach a speed of 40 km/h.

You obviously can’t use these vehicles for very long commutes, however, what if you need to travel a short distance? Even if you have a reasonable public transport facility in the city, it might not cover the route you need to take. Take the example of a large university campus. Such a campus is often at a considerable distance from the central business district of the city where it’s located. While public transport facilities may serve the central business district, they wouldn’t serve this large campus. Currently, many people drive their cars even for short distances.

As you know, that brings its own set of challenges. Vehicular traffic adds significantly to pollution, moreover, finding a parking spot can be hard in crowded urban districts.

Well, you can reduce your carbon footprint if you use an electric car. However, electric cars are still new, and many countries are still building the necessary infrastructure for them. Your large campus might not have the necessary infrastructure for them either. Presently, electric cars don’t represent a viable option in most geographies.

As a result, you need to buy and maintain a car even if your commute is short. In addition to dealing with parking problems, you need to spend significantly on your car.

All of these factors have combined to make people sit up and think seriously about cars. Many people are now seriously considering whether a car is really the best option even if they have to commute only a short distance.

This is where micro-mobility enters the picture. When you commute a short distance regularly, e-scooters or e-bikes are viable options. You limit your carbon footprints and you cut costs!

Businesses have seen this shift in thinking, and e-scooter companies like Lime and Bird have entered this field in a big way. They let you rent e-scooters by the minute. On the other hand, start-ups like Jump and Lyft have entered the e-bike market.

Think of your campus now! The people there might need to travel short distances within the campus, and e-scooters can really help them.

How micro-mobility can benefit you

What advantages can you get from micro-mobility? Let’s take a deeper look into this question.

Micro-mobility can offer several advantages to the people on your campus, e.g.:

• Affordability: Shared e-scooters are cheaper than other mass transportation options. Remember that the people on your campus will use them on a shared basis, and they will pay for their short commutes only. Well, depending on your operating model, you might even let them use shared e-scooters or e-bikes for free!
• Convenience: Users don’t need to worry about finding parking spots for shared e-scooters since these are small. They can easily travel from point A to point B on your campus with the help of these e-scooters.
• Environmentally sustainable: Shared e-scooters reduce the carbon footprint, moreover, they decongest the roads. Statistics from the pilot programs in cities like Portland and Denver showimpressive gains around this key aspect.
• Safety: This one’s obvious, isn’t it? When people on your campus use small e-scooters or e-bikes instead of cars, the problem of overspeeding will disappear. you will see fewer accidents.

Comprehensive Guide To Python Dunder Methods

Python has a set of magic methods that can be used to enrich data classes; they are special in the way they are invoked. These methods are also called “dunder methods” because they start and end with double underscores. Dunder methods allow developers to emulate built-in methods, and it’s also how operator overloading is implemented in Python. For example, when we add two integers together, 4 + 2, and when we add two strings together, “machine” + “learning”, the behaviour is different. The strings get concatenated while the integers are actually added together.

The “Essential” Dunder Methods

If you have ever created a class of your own, you already know one of the dunder methods, __init__(). Although it’s often referred to as the constructor, it’s not the real constructor; the __new__() method is the constructor. The superclass’s  __new__() , super().__new__(cls[, ...]), method is invoked, which creates an instance of the class, which is then passed to the __init__() along with other arguments. Why go through the ordeal of creating the __new__() method? You don’t need to; the __new__() method was created mainly to facilitate the creation of subclasses of immutable types (such as int, str, list) and metaclasses.
