Code Smell 180 - BitWise Optimizations
Bitwise operators are faster. Avoid these micro-optimizations
TL;DR: Don't use bitwise operators unless your business model is bitwise logic.
Problems
Readability
Clevereness
Premature Optimization
Maintainability
Bijection Violation
Solutions
Improve readability
Context
Some clever programmers solve problems we don't have.
We should optimize code based on evidence and use the scientific method.
We should benchmark only if necessary and improve code only if really necessary and bear the cost of changeability and maintainability.
Sample Code
Wrong
const nowInSeconds = ~~(Date.now() / 1000)
Right
const nowInSeconds = Math.floor(Date.now() / 1000)
Detection
[X] Semi-Automatic
We can tell our linters to warn us and manually check if it is worth the change.
Exceptions
Real-time and mission-critical software.
Tags
Premature Optimization
Conclusion
If we find this code in a pull request or code review, we need to understand the reasons. If they are not justified, we should do a rollback and change it to a normal logic.

1. Rust GUI and GTK calc
Introduction
I’ve started to learn rust GUI and GTK probably in june 2022. All this time I tried to get a job (and still trying) and was doing some tests tasks which took some time. And september was something like no-code month for reasons.
I found GTK documentation for Rust is pretty weird sometimes. I just had to google instead of reading docs. Some answers I found on the old forums, some I got by myself. Anyway I like the fact I can write at least something simple. It was interesting and I’…

3. 9-JS OOP: Getters And Setters In Javascript Classes
What are Getters and Setters?
Getters and setters are methods that are used to get and set the value of a property member in a class.
So a getter method is a method that is prefixed with get keyword, and it allows us to get a certain value when a user tries to access that getter property.
An example of a getter method:
class Human {
private _name: string = 'Hasan';
get name() {
return this._name;
}
}
Here we defined get name() this is a getter method, it allows us to return whatever we…

It’s easy to see the appeal of folding phones — they are big screen devices that get smaller to fit in your pocket. It’s also easy to see the drawbacks; as much as Samsung tries to hide it with trade-in promotions, there’s no denying the Galaxy Z Fold 4’s $1,800 price tag is too steep for the vast majority of people. The question of durability is also hard to igno…

map() method creates a new array with the results of calling a function for every array element.
const output = arr.map(function) // this function tells map that what transformation I want on each element of array
Task 1: Double the array element

1. Part 1: Introduction to Unit Testing (with examples)
Unit testing is a software testing technique in which individual units or components of a software application are tested in isolation from the rest of the system. The goal of unit testing is to validate that each unit of the software application is working as intended. A unit is the smallest testable part of an application, such as a function or a method.
For example, consider a simple function that takes two integers as input and returns their sum. A unit test for this function would involve …

2. Part 2: Catching Bugs Early
One of the main benefits of unit testing is that it allows developers to catch bugs early in the development process. By testing individual units or components of the software application, developers can identify and fix issues before they make their way into the final product. This can save a lot of time and resources compared to catching and fixing bugs later on in the development cycle or after the product has been released.
