About Trickyworld
I'm Vishal, and Trickyworld is my site. I write it for working developers, for students preparing for technical interviews, and for anyone who looks after their own servers: practical guides that get to the point, with the commands and code you need.
What Trickyworld covers
- Programming: Node.js, JavaScript and React, PHP, Laravel, Drupal and WordPress, Python and shell scripting.
- Databases: SQL, PostgreSQL and MySQL, NoSQL stores, schema design, migrations and query performance.
- Interview preparation: the questions asked for developer, database, DevOps and security roles, with worked answers.
- Security: the vulnerabilities and attacks developers and server owners have to act on, and what to change.
- AI and machine learning: explained for developers who use it in their work.
What changed
The first articles went up in 2023, when Trickyworld was a general tips site that also covered games and gadgets. It is now only about software: programming, databases, security and the tools around them. Older articles that no longer meet the standard below are being rewritten, merged into better ones, or taken down.
How the articles are written
Many news articles start as a draft from an AI writing assistant, and I say so at the end of each one. The assistant works from one primary source — the release notes, documentation or advisory the article links to — and every draft is fact-checked against that source automatically before I see it. Nothing is published without me: I review and edit each draft and publish it myself, and where I've run or tested something, my hands-on notes at the top of the article say what I did.
The full rules — sources, testing, AI use, corrections and updates — are in the editorial policy.
Corrections and contact
If something here is wrong, out of date or doesn't work on your setup, tell me through the contact page. I fix mistakes and note significant corrections in the article itself.
