On the machine you used to flash the SD card, or on another Raspberry Pi attach the NVMe over USB and the SD card via th

In the car example, color and brand are two attributes associated with every instance, or car, created with the program. On the other hand, methods would be actions performed with or by the car, such as driving. A more computer-oriented example would be a file in a directory, as every file has a name, a size and a date of when it was created.,And what about TRIM support? As you can see from above, the drive and the enclosure picked both support TRIM on a Raspberry Pi 4 under Raspberry Pi OS. For an external drive, you sometimes have to enable TRIM explicitly by setting the provisioningmode. The Arch Linux wiki has an excellent article on how to do this under “Solid state drives”.,To make it easier for computers to understand these new concepts, Python uses a programming pattern called object-oriented programming, which models concepts using classes and objects. This is a flexible, powerful paradigm where classes represent and define concepts, while objects are instances of classes. In the car example, we can create a class called car that defines its characteristics to the computer. We would be able to create thousands of instances of that class car, which are the individual objects of that class.,A German pharmaceutical company, Bayer, that produces aspirin, commercialized heroin in the 1890s as a cough, cold, and pain remedy. Bayer even marketed heroin for use in children as late as 1912, years after reports began to surface about how it could be a dangerous drug.,As you can see in the image above, when we use the type function as we just did here, Python tells us which class the value or variable belongs to. And since integers and strings are classes, they have a bunch of attributes and methods associated with them. You can access attributes and methods of a class with the dir function in Python, as shown below:,In order to begin understanding the intuition behind this programming technique, let’s take a look at an initial example. Imagine that you have to describe a car to someone who’s never seen one before, how would you do it?,Now mirror the SD card to the NVMe, but be really careful with the device names. You don’t want to overwrite your OS on the machine you’re using to do the mirroring operation.,What about UASP you say? UASP stands for USB Attached SCSI and according to StarTech can enable better throughput over USB and decrease CPU usage. It just happens to be enabled on the hard-drive and enclosure combination I’ve picked out for you in the bill of materials.,Are you thinking of putting your Raspberry Pi on the Internet, or wanting a way to access it remotely? Checkout the inlets project for an unlimited open source tunnel that you can host yourself.,You might want to start saying that it’s a wheeled motor vehicle used for transportation. Also, you might say that there are several brands of car-maker companies, which make different types of cars that fulfill various needs. In an even more basic level you might say that it has four tires, that they carry up to five people in most cases and that they are mainly used to transport people, not goods.,When explaining to a computer what kind of object this is, it’s a good idea to approach it in a similar way. Computers have no innate idea of what a car is, why were they created or who uses them. And if you want your computer to correctly understand the object, a car in this case, you have to clearly explain which are its attributes.,This quote from Bill Gates illustrates the purpose of this article. Understanding object-oriented programming allows you to develop a way of thinking and implementing code and my aim is to make it clear-sky simple to you. After all, one of the main reasons why we code, or at least want to learn how to do so, is to automate routine tasks. O.O.P. serves as a trick to achieve this purpose, as the Co-Founder of Microsoft says.,Another trick in software is to avoid rewriting the software by using a piece that’s already been written, so called component approach which the latest term for this in the most advanced form is what’s called Object Oriented Programming. — Bill Gates.,Walk-through — install Kubernetes to your Raspberry Pi in 15 minutes Dust off your Raspberry Pi, it’s time to install Kubernetes, and this time, it’s going to be painless — with metrics…alexellisuk.medium.com,The idea of object-oriented programming might sound abstract and complex, but if you’ve programmed any software you might have already used objects without even realizing it. Almost everything in Python is an object, all of the numbers, strings, lists, and dictionaries are included in this type of element. The core concept of object-oriented programming comes down to attributes and methods associated with a type:
