Posting after a long time LeetCode Weekly Contest recap Q1: Easy. Q2: That 951 test case was the real culprit. The modular inverse trick was the key. 💀 Q3: Absolutely cooked me. An interesting brute force + DP problem. Q4: Couldn't even give it a proper attempt. #LeetCode

@code_anamously @striver_79 @takeUforward_ Comeback iss saal hi hoga🔥🔥

Day 36/45✅ Todays problems were 1) Level Order Traversal 2) Maximum Depth in BT 3) Diameter of Binary Tree 4) Check for balanced binary tree #DSA #LearnInPublic #SDESheetChallenge @striver_79 @takeUforward_

Just shipped NetDiag v1.0 — a lightweight Linux diagnostics tool built with Bash 🐧 - System monitoring - Battery health - Network checks (IP, DNS, internet) - Listening ports Feedback welcome! github - github.com/batcoder-1/Net… #linux #bash #devops #opensource #100DaysOfCode

3/4 solved… and once again my silly mistakes won 🥲 A literal divide by zero in Q2 🤦‍♂️ Q3 was actually super fun with bfs Need to seriously improve my bitwise for Q4 #LeetCode #WeeklyContest #DSA #CompetitiveProgramming #BFS #Bitwise #Coding #ProblemSolving

Choked on Q2 today 😭 I knew it was a Binary Search problem but couldn’t implement it under pressure. Ended up solving Q3 somehow 💀 For me honestly: Q2 > Q3 #LeetCode #WeeklyContest #CompetitiveProgramming #DSA #BinarySearch #Coding

Built a simple WebSetup automation script Deploy static sites + React(Vite) projects locally with Nginx in one go No more manual config + asset path issues github - github.com/batcoder-1/Web… #DevOps #Nginx #React #Vite #Linux #Automation #WebDevelopment

Back to Codeforces after a long break — first contest of the year. Div 3 that felt more like Div 2. B was tricky, and greedy failed for C, so BFS it was. Lots to analyze and improve. #Codeforces #Div3 #CompetitiveProgramming #CP #Learning

@cyber_razz B

LINUX KNOWLEDGE CHECKPOINT A Linux administrator wants to find all files owned by a specific user across the entire system. Which command is the BEST choice? A. ls -l / B. find / -user <username> C. grep <username> /etc/passwd D. stat <username>

Gave a LeetCode Weekly Contest after a long time Solved 3/4 problems. Got a penalty on Q3 due to a classic signed integer overflow 😅 #LeetCode #CompetitiveProgramming #DSA #CodingJourney #Bitmasking #ProblemSolving #Consistency

Happy New Year to All 😁 #NewYear2026 #NewYearCelebration

🧵 Tweet 5 – Closing + contribution Planning to contribute these fixes back to the original repo. Debugging real systems > tutorials. #Docker #DevOps #Linux

🧵 Thread: Deploying an open-source project locally using Docker + Nginx. Not building something new — just learning what actually breaks when running real projects on a modern system Lessons below 👇 #DevOps #LearningInPublic #Linux

🧵 Tweet 4 – Issue 2 Issue 2: Port 80 conflict between host Apache and Docker Nginx.Apache was running by default on my system, so Nginx containers failed to bind to port 80.Took a while to realize this wasn’t a Docker bug, but a host service issue. #Docker #DevOps #Linux

🧵 Tweet 3 – Issue 1 Issue 1: The Java service wouldn’t build because openjdk:8-jre has been removed from Docker Hub.Had to update the Dockerfile to use eclipse-temurin:8-jre, which is now the recommended OpenJDK replacement. #Docker #DevOps #Linux

🧵 Tweet 2 – Credit Credits to the original repository-github.com/devopshydclub/… I used the project as-is and focused only on deployment and setup, not application logic.Working with someone else’s code surfaced problems you don’t usually see in tutorials. #Docker #DevOps #Linux

@hazybishop First one is simple pattern printing Second one is greedy with sorting Third one is bs on answer And in the last i thought it was greedy But it is dp on subsequences Also some questions related to increasing subsequence might get repeated

Gave my Visa OA today. Took the same OA ~2 months back — this time performance was clearly better. Solved 3/4 completely and 1 partially. #VisaOA #Coding #SoftwareEngineering #CompetitiveProgramming #LifeOfACoder

@kismiss_X Didnt get the interview call 🙃

@roger5364 What is the result of OA?

Finally set up Ubuntu dual-boot alongside Windows. Faced driver issues, GNOME freezes, Wi-Fi bugs — fixed them step by step. Not fancy, but a solid foundation for actually understanding Linux.🐧💜 #Linux #Ubuntu #LearningInPublic

Practicing basic web server setup on Ubuntu using Apache. Super helpful for understanding how servers handle HTTP requests and serve static content. Simple setup, but a solid foundation for understanding how web servers actually work. #Linux #DevOps #LearningInPublic

@AmansAgarwal Thanks aman

@roger5364 That's a impressive improvement
