- everything is a file (Unix) - everything is an object (Java) - everything is a string (Perl) - everything is a global variable (PHP) - everything is an app (Macromedia Flash) - everything is XML (too many to name) - everything is an HTML attribute (Angular.js) - everything is a stream (RxJS) - everything is a component (React) - everything is a hook (React but 5 years later) - everything depends (senior developer)

The tower has caught the rocket!!

Famous words of IND Proud #RatanTata

You were and still will remain a true leader. May your soul Rest in Peace.🙏🏻🙏🏻🙏🏻

The clock has stopped ticking. The Titan passes away. #RatanTata was a beacon of integrity, ethical leadership and philanthropy, who has imprinted an indelible mark on the world of business and beyond. He will forever soar high in our memories. R.I.P

@bhash What a language from a CEO. Are you for real bro? Never using OLA products ever again. What a disgrace to the society.

Chot lagi? Dard hua? Aaja service center. Bahut kaam hai. I will pay better than your flop shows pay you. Show your audience how much you truly care and whether you’re only gas and BS.

🚀Just found the best resource for learning Redux on @freeCodeCamp @_sohamderoy! 👉🏻It covers Redux actions, the Redux store, reducers, and the entire workflow. 👉🏻Everything is so clear and easy to understand. Highly recommend! freecodecamp.org/news/what-is-r… #Redux #javascript #React

🐲Dragonfly is a drop-in #Redis replacement built for modern data workloads. If you are running a large Redis instance, Dragonfly can: - reduce costs (up to 80%) - boost performance (30X throughput on same instance) - simplify operations (vertical scaling)

𝗧𝗼𝗽 𝟮𝟬 𝗦𝗤𝗟 𝗾𝘂𝗲𝗿𝘆 𝗼𝗽𝘁𝗶𝗺𝗶𝘇𝗮𝘁𝗶𝗼𝗻 𝘁𝗲𝗰𝗵𝗻𝗶𝗾𝘂𝗲𝘀 Here is the list of the top 20 SQL query optimization techniques I found noteworthy: 1. Create an index on huge tables (>1.000.000) rows 2. Use EXIST() instead of COUNT() to find an element in the table 3. SELECT fields instead of using SELECT * 4. Avoid Subqueries in WHERE Clause 5. Avoid SELECT DISTINCT where possible 6. Use WHERE Clause instead of HAVING 7. Create joins with INNER JOIN (not WHERE) 8. Use LIMIT to sample query results 9. Use UNION ALL instead of UNION wherever possible 10. Use UNION where instead of WHERE ... or ... query. 11. Run your query during off-peak hours 12. Avoid using OR in join queries 14. Choose GROUP BY over window functions 15. Use derived and temporary tables 16. Drop the index before loading bulk data 16. Use materialized views instead of views 17. Avoid != or <> (not equal) operator 18. Minimize the number of subqueries 19. Use INNER join as little as possible when you can get the same output using LEFT/RIGHT join. 20. For retrieving the same dataset, frequently try to use temporary sources. Do you know what is 𝗤𝘂𝗲𝗿𝘆 𝗢𝗽𝘁𝗶𝗺𝗶𝘇𝗲𝗿? Its primary function is to determine 𝘁𝗵𝗲 𝗺𝗼𝘀𝘁 𝗲𝗳𝗳𝗶𝗰𝗶𝗲𝗻𝘁 𝘄𝗮𝘆 to execute a given SQL query by finding the best execution plan. The query optimizer works by taking the SQL query as input and analyzing it to determine how best to execute it. The first step is to parse the SQL query and create a syntax tree. The optimizer then analyzes the syntax tree to determine how to run the query. Next, the optimizer generates 𝗮𝗹𝘁𝗲𝗿𝗻𝗮𝘁𝗶𝘃𝗲 𝗲𝘅𝗲𝗰𝘂𝘁𝗶𝗼𝗻 𝗽𝗹𝗮𝗻𝘀, which are different ways of executing the same query. Each execution plan specifies the order in which the tables should be accessed, the join methods, and any filtering or sorting operations. The optimizer then assigns a 𝗰𝗼𝘀𝘁 to each execution plan based on the number of disk reads and the CPU time required to execute the query. Finally, the optimizer 𝗰𝗵𝗼𝗼𝘀𝗲𝘀 𝘁𝗵𝗲 𝗲𝘅𝗲𝗰𝘂𝘁𝗶𝗼𝗻 𝗽𝗹𝗮𝗻 with the lowest cost as the optimal execution plan for the query. This plan is then used to execute the query.

CSS can be tricky – after all, there are many different ways to do one thing. But there are some helpful tools that can make your life easier, like Tailwind CSS. In this guide @_sohamderoy shows you what Tailwind can do & how to use it in your projects. freecodecamp.org/news/what-is-t…
