Why does a search box sometimes feel fast and sometimes slow? Think of typing on your phone - If your phone checks spelling every few letters while you type - that’s throttle. - If your phone waits until you stop typing for 2–3 seconds before checking - that’s debounce. I used these ideas to fix a slow search in some of our projects - Throttle is good when you need updates at regular intervals (like scroll events, live data, or APIs with limits). - Debounce is good when you only need the final action (like search suggestions, form checks, or auto-saving drafts). In React, we often use debounce from lodash to handle this. Along with that - Wrap functions in useCallback for stability - Clean up on unmount - Cancel timers when input changes This reduced server calls by ~70% and made the search feel smoother. In short Need steady updates? Use throttle. Need the last action after typing stops? Use debounce. #debounce #throttle

Use nameof() to Keep Code Clean Sometimes we write variable names as text: Console.WriteLine("user"); ❌ Problem: if you rename user, this text will not change → possible bugs. ✅ Solution: use nameof() void Save(User user) { ArgumentNullException.ThrowIfNull(user, nameof(user)); } Now if you rename user, this code updates automatically. Less bugs, cleaner code!

All of a sudden your applications crash, do not respond, show multiple errors and are not working properly anymore. The first instinct is observe the application logs, but they do not get printed. Most probably the culprit is a filled up partition with no space left. 𝘥𝘧 -𝘩 | 𝘴𝘰𝘳𝘵 -𝘬 5 -𝘳𝘩 There are no advanced algorithms going around, we are just listing the partitions and then sorting them based on the 5th column which will depict the used percentage. Sorting is done in the descending order for numerical values. Now go to these locations and move or remove files based on least priority. Or else you can create a compressed archive of the unused files using 𝘵𝘢𝘳 -𝘤𝘻𝘧 𝘧𝘪𝘭𝘦.𝘵𝘢𝘳.𝘨𝘻 𝘧𝘪𝘭𝘦 and decide later whether to remove them or not.

I have been comparing Grok code and Claude code. In this comparison they run side-by-side generating a console application that can read an excel file. These file-system enabled AIs are so powerful I can't stop using them. If you haven't tried it yet, you are in for an incredibly experience! See the detailed comparison below.

Mobile Multi-Select Long-requested, you can now select multiple nodes on Mobile. Long-press a node, select several, then use the drag-handle to move them. Use the bottom toolbar to change item type (todos, bullets, quotes, etc.), duplicate, move or mirror.

That error message, "7 Error Invalid Number," means the number you tried to send a message to isn't recognized as a valid phone number. Here's what that can mean: The number is too short or too long. A valid U.S. mobile number is 10 digits. There are extra characters. Your message might have included symbols or letters in the phone number. It's a landline number. Not all messaging services can send texts to landline numbers. It's a short code that isn't formatted correctly. Short codes are usually 5 or 6 digits. To fix this, double-check the number you're trying to send to and make sure it's a valid 10-digit mobile number or a correct short code. If you're still having trouble, you might want to try re-typing the number from scratch to avoid any hidden characters.

Amp CLI now has custom slash commands. They allow you to insert pre-defined or dynamically-generated text into the prompt input.

Context baby. It’s all about the context. Someone’s starting a walk-through of software. They load up their IDE to start & part of a script is immediately shown on screen. Within 5 seconds you declare, “Well that’s not needed. You should be using a docker-compose file”. What might be missing here. Any ideas? 😉
