Vim Tip: Navigate to Matching Brackets with %

For quite some time, I used to support more than one rust async runtime in a single crate. After spend several hours troubleshooting which project has enabled two conflicting feature flags in my crate, I came up with few conclusions: 1. If you need support tokio, smol, monoio, compio or glomio as async runtimes, isolate parts which has calls to their APIs into separate crates, at debugging time you won’t have code paths being mistakenly activated 2. Type aliases are useful, but don’t use them to simple give another name to a struct, like File or RwLock, that will cause compilation errors if feature flags aren’t additive, but exclusive. In short, take a wide picture of your solution, if you codebase has parts which are clearly exclusive to one or another runtime, please save time and do not use a feature flag to support both of them, it will not only add code bloat, but verbose, hard to maintain and debug. #rust #programming #async #bestpratices #softwaredesign #featureflags

Solved Add Two Numbers using linked lists. At first, the pointer-based structure was confusing, but breaking it down into simple steps made it manageable. Approach: Traverse both linked lists Add digits one by one Maintain carry (just like normal addition) Build a new linked list for the result #DSA #LinkedList #CPP #Coding

Brute force works… But it’s not always smart ❌ This problem is a perfect example 👇 👉 Find maximum sum of subarray of size K Naive approach: Check all windows → O(n × k) Optimized approach: Use Sliding Window → O(n) 💡 What changes? You stop repeating work. Instead of recalculating sum every time: → Subtract old element → Add new element That’s it. 👉 Less loops = More efficiency #ProblemSolving #DSA #Coding #Developers

LeetCode POTD | Day 8 Maximum Non-Negative Product in a Matrix Today’s problem was a good reminder that signs matter… a lot. At first, it felt like a normal DP path problem. But negative numbers completely change the game. What worked: • Track both max and min product at each cell • Because a negative × negative can suddenly become max • Classic DP, but with a twist What I learned today: Whenever negatives are involved, don’t just track the best… track the worst too. Because sometimes, the “worst” turns into the best. Pattern I’m noticing: DP problems are less about memorizing solutions and more about understanding what state to carry forward. Day 8 of solving LeetCode POTD consistently. Slowly getting better at spotting these patterns early. If you solved this, did you also maintain both min and max DP states? #LeetCode #DSA #DynamicProgramming #CodingJourney #SoftwareEngineering #POTD

Practiced problem-solving by implementing an optimized solution for Valid Palindrome. 🔹 Approach: Two-Pointers 🔹 Time Complexity: O(n) 🔹 Space Complexity: O(1) Also designed a structured PPT to explain the intuition clearly. #SoftwareEngineering #DSA #Coding #GitHubProjects

Here’s this month’s recap of the VS Code and InterSystems-related updates that are relevant to IRIS developers. This month includes: • Highlights from VS Code 1.110  • Updates to the InterSystems ObjectScript and Server Manager Extensions • Our Marketplace pick for February Everything is summarised in the PDF carousel → swipe through for each section. Let us know in the comments if you try any of these features or VS Code extensions, and what you think. If you’re moving from Studio to VS Code, or want to strengthen your team’s development workflow, we also run practical, hands-on VS Code training. Happy coding! #VSCode #InterSystemsIRIS #InterSystems #VSCodeExtensions #Coding

Also, the VS Code team just announced they're changing from monthly iterations to weekly ones. Watch those version numbers grow!

A React component logs a surprise string even though a default prop is defined. The component uses destructuring with a fallback value and also sets defaultProps. It gets invoked directly as a regular function, not via JSX. In production this can mask missing props, leading to silent bugs. Logs may mislead you during debugging sessions. Automated tests that call the component as a function could pass falsely. Comment A, B, C, or D with the string you think will be logged and defend your choice. #tsx #React #Programming #Backend #CodingInterview
