  A critical vulnerability in MongoDB, named MongoBleed (CVE-2025-14847), was disclosed over the holiday season, accompanied by the release of a public proof-of-concept exploit on Christmas Day. This situation presents a significant security risk for organizations utilizing this database technology. The Core of the Vulnerability The fundamental issue lies within MongoDB's handling of zlib compression. This flaw allows a remote, unauthenticated attacker to exploit the system and leak portions of the server's memory. Such a leak can expose highly sensitive information, including user credentials and session tokens, without the need for any prior authentication. The attack can be initiated by anyone with network access to the vulnerable MongoDB instance. Key Risk Factors Several factors heighten the severity of this vulnerability: Pre-Authentication Exploit: The vulnerability can be triggered before the server performs any credential checks, making it accessible to any attacker wh...

Using Generic in TypeScript about types in the Code

# Using Generic in TypeScript about types \<T> in the Code ## Question 1: Here what is this <T> means? ```typescript const addID = <T>(obj: T) => {   let ID = Math.floor(Math.random() * 100);   return ({...obj, ID}); } ``` ## Answer 1: In the code snippet you've provided, `<T>` is a **generic type parameter** in TypeScript. It allows you to write a function that can work with any type of object while still maintaining that object's specific type information. When you use the function `addID`, you can pass in an object of any type, and TypeScript will understand that the returned object will be of the same type as the input, plus the additional `ID` property. Here's a breakdown of how it works: ```typescript const addID = <T>(obj: T) => {   let ID = Math.floor(Math.random() * 100);   return ({...obj, ID}); } ``` - `<T>`: Declares a generic type `T`. - `(obj: T)`: Indicates that the function takes an argument `obj` of type `T`....

 ⭕ Whiteboarding interviews are a common way of assessing the technical and non-technical skills of candidates for software development positions. They involve solving a coding problem or designing a system on a whiteboard, either in person or virtually, while explaining your approach and reasoning to the interviewer.  ⭕ Some of the benefits of whiteboarding interviews are that they can test your problem-solving ability, communication skills, and coding proficiency in a realistic scenario. They can also help you demonstrate your creativity, collaboration, and passion for the role. However, some of the drawbacks of whiteboarding interviews are that they can be stressful, artificial, and biased. They can also favor memorization over understanding and overlook other aspects of your skills and experience.  ⭕ If you want to ace a whiteboarding interview, you should practice beforehand, prepare for the interview setting, set objectives and expectations, create a good candidate ...
