In JavaScript, a promise is an object that represents a value that may not be available yet, but will be at some point in the future. Promises are commonly used for asynchronous programming, such as fetching data from a server or waiting for a user input.
Triggers in MSSQL
A trigger is a special type of stored procedure in Microsoft SQL Server that automatically executes when an event occurs, such as an INSERT, UPDATE, or DELETE statement. Triggers can be used to enforce business rules, maintain data integrity, or perform actions automatically in response to changes in the data.
Most Common Git Commands
You can easily find GUI to accomplish following operations these days but here are some of the most commonly used Git commands, along with brief explanations and examples:
SQL Merge Statement & UPSERT Operation
The MERGE statement in Microsoft SQL Server allows you to perform multiple actions (such as insert, update, or delete) in a single statement based on the results of a join between a target table and a source table.
CTE (Common Table Expression) in SQL
CTE (Common Table Expression) is a feature in SQL that allows you to define a temporary result set that can be used within a SELECT, INSERT, UPDATE, or DELETE statement. A CTE is similar to a derived table or subquery, but has some advantages over those techniques, including improved readability, reusability, and optimization opportunities.
SQL Window Functions
SQL Window Functions are a feature of SQL that allow you to perform calculations across rows within a set of rows, called a "window". The window is defined using the "OVER" clause and can be used to perform operations such as ranking, cumulative sums, running totals, and more. These functions provide a more concise and efficient way to perform calculations that would otherwise require complex subqueries or self-joins.
OpenLDAP: Definition and Summary
OpenLDAP is an open-source implementation of the Lightweight Directory Access Protocol (LDAP), a network protocol used to access and manage directory information services. It provides a centralized repository for user authentication, authorization, and other information, making it an essential component in many enterprise IT systems. OpenLDAP supports various directory storage backends and is widely used for managing user identities and access control in large organizations.
How to implement TOTP to Laravel
To implement TOTP in Laravel, you can use a library such as "Google Authenticator" or "TOTP".
Here are the general steps you can follow to implement TOTP in Laravel:
Logic behind 2FA
Two-factor authentication (2FA) codes provide an extra layer of security for login systems by requiring the user to present two different forms of identification. The first factor is usually a password, and the second factor is generated by an application, such as Google Authenticator, or sent to the user's phone as a text message. The 2FA code acts as a one-time password that is only valid for a short period of time and is required in addition to the password in order to log in. This helps ensure that even if someone has obtained the user's password, they still cannot access the account without the 2FA code, adding an extra barrier to prevent unauthorized access.
How to access local MongoDB server from a Docker Environment
It is actually pretty easy. In my case I needed to reach from Laravel Sail to my local MongoDB Database.
