Security, DevOps & Trading Tech — Practical Guides

I’ve been hashing things for years — verifying file downloads, generating checksums for deployments, creating HMAC signatures for APIs. And every single time, I end up bouncing between three or four browser tabs because no hash tool does everything I need in one place. So I built HashForge. The Problem with Existing… Read more →

Pasting a nested API response into an online JSON formatter means your auth tokens, user data, and internal endpoints are now on someone else’s server. A privacy-first JSON tool that runs entirely in your browser handles the same formatting, diffing, and path-querying—without the data exfiltration risk. **👉 Try JSON Forge now:… Read more →

Parsing JPEG EXIF data in the browser without dependencies means reading a binary format—TIFF-structured IFDs, big-endian and little-endian byte orders, and tag types that reference offset chains. Most tutorials hand-wave this complexity, but if you want zero-dependency EXIF extraction, you need to understand the byte layout. Why Parse EXIF Data in… Read more →

I ran the same 10 images through five different online compressors and measured everything: output file size, visual quality loss, compression speed, and what happened to my data. Two of the five uploaded my photos to servers in jurisdictions I couldn’t identify. One silently downscaled my images. And the one… Read more →

The Pomodoro Technique — work for 25 minutes, break for 5 — has been around since 1987. The science backs it up: time-boxing reduces procrastination and improves focus. But here’s the problem: most people try it for three days and quit. Not because the technique fails, but because a plain… Read more →

I built 3 of these tools because I got tired of desktop apps phoning home. After 12 years as a security engineer in Big Tech, I’ve watched network traffic from “offline” desktop apps — the telemetry, the analytics pings, the “anonymous” usage data that includes your file paths and timestamps….

Every time you take a photo with your phone, the exact GPS coordinates are embedded in the image file. When you share that photo online — on forums, marketplaces, or messaging apps — anyone who downloads it can see exactly where you were standing. Here’s how to remove it in… Read more →

You need to send a photo by email but it’s 8MB. You need to upload a product image but the CMS has a 2MB limit. You need to speed up your website but your hero image is 4MB. The solution is always the same: compress the image. But most tools… Read more →

When I complained about noise to my building manager, they asked for evidence. “It’s loud” wasn’t enough. They wanted dates, times, and decibel readings. So I built an app that gives you all three — and generates a report you can actually hand to someone. The Noise Complaint Trap 📌 TL;DR: When… Read more →
