Mobile view bug

There is a music streaming platform, which is supposed to only let registered users to play and download musics from it. On the desktop view of web app, as expected you can only see available playlists but no play button. So you have to register or log in, buy a subscription and then play or download a playlist. One of steps in testing a web app, is to check the mobile view of it. There are multiple ways to test that. The simplest is to make your browser window small, so according to viewable p...

How I built Enkrateia: an AI platform that generates complete books and evolved into a social system

I’ve been working on a project called Enkrateia, an AI-powered platform designed to generate complete books from structured user inputs. The idea is simple: users define key elements such as title, genre, characters, plot, setting, and narrative tone. The system then generates a full book, structured chapter by chapter. What started as a pure AI writing tool gradually evolved during development. After early testing, I noticed that users didn’t just want to generate books — they wanted to inter...

Building Massive Gradient Images Without Running Out of Memory Using pyaitk.CLSE

When generating images in Python, most developers load the entire image into memory before saving it to disk. That works well for small images. But what happens when you start working with images that are thousands of pixels wide and tall? A 4000×4000 RGB image contains 16 million pixels . As image sizes continue to grow, memory usage quickly becomes a bottleneck. This is where pyaitk.CLSE's StreamingWriter becomes useful. Instead of storing the entire image in memory, Streamin...

Why Your Word Counter Gives Different Results Than Others (And How They All Work)

You paste the same text into two different word counters and get different results. It happens more often than you'd expect. Here's why — and how to know which count to trust. The core problem: what is a "word"? Every word counter has to answer this question, and there's no single right answer. The most common approach is whitespace splitting : split the text on any space or line break, count the chunks. In JavaScript: const wordCount = text . trim (). spli...

DRY is not for UI

When we talk about UI, we almost always start by thinking about small components we can reuse across the frontend. And of course we can't reuse every component. But where exactly does that border of reusability lie — and how do we decide which components are worth reusing and which aren't? To answer that, I'll first walk you through a problem we ran into on our product, and then show you how we solved it. The problem: one browsing experience, many pages On our product we sho...

AI for Data Pipelines & ETL in 2026: dbt AI vs Airflow vs Prefect vs Fivetran

AI for Data Pipelines & ETL in 2026: dbt AI vs Airflow vs Prefect vs Fivetran — Which One Saves You 20+ Hours/Week? Data pipelines are the unglamorous backbone of modern apps. Transform raw data into usable insights, and your whole business runs smoother. Break your ETL, and your dashboards, reports, and analytics go dark. For years, building and maintaining data pipelines meant writing boilerplate SQL, debugging scheduling issues, and dealing with failed transforms at 3am. The manual...

How to send contact form emails with a simple token-based endpoint

Most small websites eventually need the same thing: a contact form that sends an email. That sounds simple, but the implementation often becomes more work than expected: SMTP credentials mail libraries server-side validation anti-abuse handling formatting the submitted fields deployment differences between hosts I built FlapMail as a lightweight way to handle this pattern with a token-based submit endpoint. It is meant for transactional messages such as: contact fo...

AWS SAA: 10 Core Concepts (Explained for Infrastructure Engineers)

This post covers what I learned while preparing for AWS_SAA — IAM, EC2, Load Balancing, Auto Scaling, RDS, Route 53, S3, CloudFront, and messaging services. I'm writing this for engineers who already understand infrastructure, so I'm skipping the basics and going straight to what the exam actually tests. 1. IAM — It's About Least Privilege, Not Just Access IAM sounds simple until the exam starts testing edge cases. Here's what actually matters: The model: Users → Groups → Po...

Leetcode 150 | Day 4: Majority Element - Naive vs. Optimized

Leetcode 169 asks us to identify the majority element in a given array. The majority element is defined as the element that appears more than n / 2 times. We are told that we can assume such an element always exists. For both approaches we will use the following value: nums = [2, 4, 2, 2, 4, 4, 4] Approach 1: Naive (Frequency Map) This approach uses a Map to count the frequency of each element in the array. function majorityElement ( nums ) { ...

5 Production Mistakes That Changed How I Build Express APIs

I stopped thinking APIs break because of “complex code”. They break because of boring things you didn’t take seriously. Here are 5 lessons from production: 1. Validate early or suffer later I used to validate inside the logic. Then weird bugs started appearing far from the source. Now I just kill bad requests immediately: if ( ! req . body . email || typeof req . body . email !== " string " ) { return res . status ( 400...

Honestly, how I Saved My Bootcamp Project Budget Using AI Data Extraction (A Complete Guide From Someone Who Just Figured It Out) I have to be honest with you. Three weeks ago, I had no idea what "data extraction" even meant in the AI world. I thought it was just... parsing JSON files? Boy, was I wrong. When my bootcamp instructor dropped a project brief on us that required pulling structured info from a pile of messy PDF invoices, I was absolutely convinced I was going to have to write regex...

How I Generated a 100-Million-Pixel Julia Set on a 4 GB RAM PC Using Python

Fractals have fascinated programmers for decades. From the Mandelbrot Set to Julia Sets, these mathematical structures can generate breathtaking patterns from surprisingly simple equations. The challenge isn't generating a fractal. The challenge is generating one at extreme resolutions . A 10,000 × 10,000 image contains: 100,000,000 pixels That's 100 million pixels . Many image-generation approaches attempt to store the entire image in memory before saving it t...
