Best Programming Languages for Hacking:

1. Python
It’s no surprise that Python tops our list. Referred to as the defacto hacking programing language, Python has indeed played a significant role in the writing of hacking scripts, exploits, and malicious programs.

2. C
C is critical language in the Hacking community. Most of the popular operating systems we have today run on a foundation of C language.
C is an excellent resource in reverse engineering of software and applications. These enable hackers to understand the working of a system or an app.

3. Javascript
For quite some time, Javascript(JS) was a client-side scripting language. With the release of Node.js, Javascript now supports backend development. To hackers, this means a broader field of exploitation.

4. PHP
For a long time now, PHP has dominated the backend of most websites and web applications.
If you are into web hacking, then getting your hands on PHP would be of great advantage.

5. C++
Have you ever thought of cracking corporate(paid) software? Here is your answer. The hacker community has significantly implemented C++ programming language to remove trial periods on paid software and even the operating system.

6. SQL
SQL – Standard Query Language. It is a programming language used to organize, add, retrieve, remove, or edit data in a database. A lot of systems store their data in databases such as MySQL, MS SQL, and PostgreSQL.
Using SQL, hackers can perform an attack known as SQL injection, which will enable them to access confidential information.

7. Java
Despite what many may say, a lot of backdoor exploits in systems are written in Java. It has also been used by hackers to perform identity thefts, create botnets, and even perform malicious activities on the client system undetected.

How Coders Can Survive—and Thrive—in a ChatGPT World

Artificial intelligence, particularly generative AI powered by large language models (LLMs), could upend many coders’ livelihoods. But some experts argue that AI won’t replace human programmers—not immediately, at least.

“You will have to worry about people who are using AI replacing you,” says Tanishq Mathew Abraham, a recent Ph.D. in biomedical engineering at the University of California, Davis and the CEO of medical AI research center MedARC.

Here are some tips and techniques for coders to survive and thrive in a generative AI world.

Stick to Basics and Best Practices
While the myriad AI-based coding assistants could help with code completion and code generation, the fundamentals of programming remain: the ability to read and reason about your own and others’ code, and understanding how the code you write fits into a larger system.

Find the Tool That Fits Your Needs
Finding the right AI-based tool is essential. Each tool has its own ways to interact with it, and there are different ways to incorporate each tool into your development workflow—whether that’s automating the creation of unit tests, generating test data, or writing documentation.

Clear and Precise Conversations Are Crucial
When using AI coding assistants, be detailed about what you need and view it as an iterative process. Abraham proposes writing a comment that explains the code you want so the assistant can generate relevant suggestions that meet your requirements.

Be Critical and Understand the Risks
Software engineers should be critical of the outputs of large language models, as they tend to hallucinate and produce inaccurate or incorrect code. “It’s easy to get stuck in a debugging rabbit hole when blindly using AI-generated code, and subtle bugs can be difficult to spot,” Vaithilingam says.

You will not learn system design in a month.
You will not master DSA in a month.
You will not suddenly understand how to solve problems at scale in a month.
You won’t grasp scalability, databases, and caching overnight.

And you most definitely won’t internalize every distributed system pattern just by reading a few blogs.

Because software engineering is an ocean: deep, vast, and ever-expanding.
And you can’t cross an ocean in a single leap.

In a month, you’ll realize you’re only scratching the surface.
You’ll see more gaps than answers.
You’ll feel like there’s too much to learn and too little time.

But that’s where most people give up.
That’s where frustration makes them quit.

Don’t be one of them.

Take it one step at a time.

Real expertise doesn’t come from rushing. It comes from consistent, deliberate learning over years.

It comes from revisiting the same concepts and seeing them from new perspectives each time.

So trust your own pace.
Stay in the game long enough to connect the dots.

And one day, the same concepts that once seemed impossible will feel like second nature.

Just keep collecting buckets.

How do analysts use SQL in a company?

SQL is every data analyst’s superpower! Here's how they use it in the real world:

Extract Data

Pull data from multiple tables to answer business questions.

Example:

SELECT name, revenue FROM sales WHERE region = 'North America';

(P.S. Avoid SELECT *—your future self (and the database) will thank you!)


Clean & Transform

Use SQL functions to clean raw data.

Think TRIM(), COALESCE(), CAST()—like giving data a fresh haircut.


Summarize & Analyze

Group and aggregate to spot trends and patterns.

GROUP BY, SUM(), AVG() – your best friends for quick insights.


Build Dashboards

Feed SQL queries into Power BI, Tableau, or Excel to create visual stories that make data talk.

Run A/B Tests

Evaluate product changes and campaigns by comparing user groups.

SQL makes sure your decisions are backed by data, not just gut feeling.


Use Views & CTEs

Simplify complex queries with Views and Common Table Expressions.

Clean, reusable, and boss-approved.


Drive Decisions

SQL powers decisions across Marketing, Product, Sales, and Finance.

When someone asks “What’s working?”—you’ve got the answers.


And remember: write smart queries, not lazy ones. Say no to SELECT * unless you really mean it!
