#Leetcode Sql Problem Interface

Interviewer: When should you avoid using window functions? Most people think window functions are always better. They are powerful. But power without judgment is dangerous. Avoid them when a simple GROUP BY can solve the problem. Avoid them when the dataset is huge and sorting becomes expensive. Avoid them when indexing can give you a faster aggregate result. Avoid them when you don’t actually need row-level detail. Window functions shine when you need both aggregate and row data together. But if you only need one summary row per group, keep it simple. Good SQL developers know window functions. Great SQL developers know when not to use them. Performance is a thinking skill, not a syntax trick.

GROUP BY finds values. Window functions keep rows. That difference matters. #WindowFunctions #SQL

Tailwind changed how we write CSS. Utility first. Fast. No overthinking. TailwindSQL applies the same mindset to databases. Instead of jumping between ORMs, raw queries, and messy abstractions, you write simple, composable queries that feel predictable and readable. Less ceremony. Less boilerplate. Just shipping features faster.

Stop using margins for layout spacing ❌ — Start using gap instead ✅ For years we used: 👉 margin-right hacks 👉 :last-child fixes 👉 extra messy code Now with Flexbox & Grid, there’s a better way: ✨ gap — simple, clean, and professional spacing between elements. ✔ Less code ✔ No edge-case bugs ✔ Easier maintenance ✔ Modern best practice Small changes like this make a big difference in code quality and developer experience. How are you handling spacing in your layouts — margin or gap? 👇 Shared by: @mfarhan.developer

Topic: Give to CSS what belongs to CSS and to Javascript what belongs to Javascript. Spent close to two weeks trying to figure out the responsiveness of a website navigation bar without copying any AI code verbatively. I tried using my understanding to apply some tricks that I know, especially in the harmbuger menu, but I still had issues with them. During my upskill intern, I learnt that you can style with your javascript, but I have come to understand that many atimes, it's a wrong approach because, your javascript styling can override what you have done on your CSS. So, after hiding my menu using (display: none). coming to javascript to declare it flex or block became an issue. that is when I resorted to classList.toggle. Expect more problem solving tricks from me. For the developers in the building, have you had the same experience with Javascript styling, or is it preferable to you? #webdevelopers #frontenddev

Trying to Learn Tailwind CSS 🚀 Recently started learning Tailwind CSS. At first, it felt overwhelming—so many utility classes inside HTML that it almost looked like CSS merged into markup. But slowly, I’m understanding its real power. Currently exploring: Utility-first workflow Spacing system (margin, padding, gap) Flexbox & Grid utilities Responsive breakpoints (sm, md, lg, xl) Typography utilities Colors, backgrounds, shadows Hover, focus, and active states Customizing the Tailwind configuration Earlier, I used to separate CSS and styling logic. Now, design decisions happen directly in the markup. The challenges: Managing too many classes Maintaining design consistency Adapting to utility-based thinking But one thing is clear— development speed increases, and prototyping becomes much faster. New tool. New mindset. New workflow. Learning in progress — In sha Allah.
