Cursor Agent and Composer: A Practical Workflow for Daily Coding
This post was created with AI assistance and reviewed for accuracy before publishing. Cursor is an AI-native editor built on VS Code. It exposes Composer for multi-file edits and Agent for longer, tool-using runs that search and change code across your repo. Product details and defaults change frequ
CA 08 - Sort 0s, 1s, and 2s
Problem Statement: here Problem Understanding: Solution: arr = [0, 1, 2, 0, 1, 2] low = 0 mid = 0 high = len(arr) - 1 while mid <= high: if arr[mid] == 0: arr[low], arr[mid] = arr[mid], arr[low] low += 1 mid += 1 elif arr[mid] == 1: mid += 1 else: arr[mid], arr[high] = arr[high], arr[mid] high -= 1
Google Is Rewriting Your Headlines With AI: Why Title Tags No Longer Belong to You
Google confirmed on March 20, 2026 that it's testing AI-generated headline rewrites in Search results. Not truncations. Full generative rewrites that can change meaning, tone, and editorial voice. This is not a bug. It's a "small, narrow experiment" - the same language Google used before making AI O
All My Favorite Dev Tools Were on 10 Different Websites. So I Built One With Everything
I've been using JSON formatters, cron schedulers, password generators and Base64 encoders since my first day as a web developer. Always jumping between tabs, always the same ugly interfaces from 2012. Then last year JSONFormatter.org and CodeBeautify.org made the news — years of user data exposed. P
pyxclip: Cross-Platform Clipboard for Python, Backed by Rust
pyxclip: Cross-Platform Clipboard for Python, Backed by Rust Most Python clipboard libraries function as thin wrappers for system-level command-line utilities. For instance, pyperclip relies on external binaries—invoking xclip on Linux and pbcopy on macOS—while using ctypes for Windows. Similarly, x
I Built a Paid API That AI Agents Use Autonomously
Last week, Tempo and Stripe launched the Machine Payments Protocol. The idea: HTTP 402 (Payment Required) finally does something useful. An agent requests data, the server says “pay me first,” the agent pays in USDC, and the server delivers. I wanted to see how fast I could build a real paid service
🔵 Sort 0s, 1s and 2s (Dutch National Flag Algorithm)
Sorting an array containing only 0s, 1s, and 2s is a classic problem in Data Structures. Dutch National Flag Algorithm, which is highly efficient. Given an array arr[] containing only 0, 1, and 2, sort the array in ascending order without using built-in sort. Input: [0, 1, 2, 0, 1, 2] Output: [0, 0,
Kafka vs. RabbitMQ: The Post Office vs. The Time Machine
Every developer eventually hits a wall. Your standard REST APIs are timing out, your database is locked, and you realize synchronous requests just can't handle the scale anymore. Let's break it down simply: RabbitMQ is the Post Office. It takes a letter (message), looks at the address (routing key),
A 3mm Error Breaks Your Match: What 3D Facial Landmarks Do Before the Score Appears
Why 3D landmark precision is the new benchmark for biometric accuracy For developers working in computer vision and biometrics, a confidence score is often the only metric surfaced to the end user. But that score is the final output of a complex pipeline, and its reliability hinges entirely on a ste
Valid Anagram in Python Using Two Methods (Sorting & Counting)
Problem Explanation You are given two strings s and t. True if t is an anagram of s, otherwise return False. An anagram means both strings contain the same characters with the same frequency, just in a different order. Input: s = "anagram", t = "nagaram" True Input: s = "rat", t = "car" False Method
🌿Why Ecological & Biological Assessment Matters More Than Ever
In today’s rapidly changing world, understanding the health of our environment is not just important — it’s essential. Ecological and biological assessments play a vital role in identifying environmental risks, protecting biodiversity, and supporting sustainable development. These assessments help e
How I Built (and Why I Use) an SEO Pricing Calculator — The Developer's Perspective on Agency Profit Math
If you've ever done client SEO work — or built tools for agencies that do — you already know the problem: pricing is embarrassingly unscientific for an industry that loves to talk about data. Most freelancers and agencies set SEO retainer prices based on gut feeling, a look at what competitors rough
Using LLMs to do security analysis at the git diff level — what works, what doesn't, and why structured output matters
I've been experimenting with piping raw git diff output into LLMs for automated security review, and I wanted to share what I've learned because some of the results surprised me. A teammate refactored a SQL query from string concatenation to an f-string. The diff looked like an improvement: - query
I Built a Windows-Style Alt+Tab Window Switcher for macOS in Pure Swift
One of my biggest frustrations after spending years on Windows was the loss of a proper window switcher when I moved to macOS. Cmd-Tab switches between applications, not windows. If you have four Terminal windows open, you cannot directly jump to a specific one — you have to Cmd-Tab to Terminal, the
You have to invite them in
⚠️ Region Alert: UAE/Middle East This edition of the Threat Source newsletter explores the evolving landscape of identity-based attacks, using an analogy of vampire mythology to describe how attackers now seek to be "invited in" rather than forcing entry.

I Built a Free PNG to WebP Converter Using Only Frontend — Here’s What I Learned
🚀 Introduction I recently built a simple online tool to convert PNG images to WebP — and I challenged myself to do it using only frontend technologies. No backend. No file uploads to a server. At first, it sounded easy… but there were a few interesting challenges along the way. 🤔 Why I Built This
