If you want to store price in dollars such as 4.99, just store it as integer not float in database (499). And in your model add this function.
public function getPriceAttribute(){ return floatval(number_format($this->attributes["price"] / 100, 2)); } When you get the price, it is 4.99 , but it is stored as 499. This saves a huge space when you have more than 10k records in database.
The optimization aspect is to store double float values as integers in database.

SEO gives you a checklist of must-do list to rank in the first page on Google. Google indexing and ranking algorithms are getting better each day.
Computers use RAM to store data and run programs and services. So, the data / programs in RAM are temporarily available — as you use the program or data. When you shutdown your computer, RAM will be free.
RAM is faster than HDD or SSD in read and write speed. So we use it to hold the currently running programs and data. But they are expensive, so we use less of them and rely on swap file to delegate some less used data / program to it.
Invalid CSRF token This error message means that your browser couldn’t create a secure cookie, or couldn’t access that cookie to authorize your login.

A list of operators on Eloquent’s where() method When you use Eloquent’s where() method, by default it will use the = operator (i.e. ->where('fieldname','value') will generate ... WHERE fieldname = 'value'....
However you are not limited to just =. You can do something like this:

Javascript is a scripting language, created to run in the Internet browser but later used in all places!. Javascript is always shortened as js or JS.
Javascript Syntax: Variables // declare a variable var ourName; // store values myNumber = 5; myString = "myVar"; // declare variables with the assignment operator var myNum = 0; // add, subtract, multiply and divide numbers myVar = 5 + 10; // 15 myVar = 12 - 6; // 6 myVar = 13 * 13; // 169 myVar = 16 / 2; // 8 // increment and decrement numbers i++; // the equivalent of i = i + 1 i--; // the equivalent of i = i - 1; // decimals var ourDecimal = 5.
First, it’s very important to say that both Go and Rust are absolutely excellent programming languages. My goal here is not to criticize any language. In this article, I’ll try to give a brief overview of where I think Rust is the ideal choice, and where I think Go is a better alternative.
If you had to sit down and think of the programming languages which were best aligned with the motive to develop secure, microservice favoring frameworks and apps, you would again find yourself staring at the two languages.
