Reversing using C

A simple way to demonstrate common reversing tricks using C code: 1.XOR cipher execution simple repeating-key XOR extremely common in obfuscation 2.Known-plaintext attack if you know part of the plaintext, you can recover the key 3.Key length recovery detect repeating patterns in the keystream #include <stdint.h> #include <stddef.h> #include <stdio.h> #include <str...

Tired of Claude Code Ignoring Your CLAUDE.md? I Built claudemd-guard

Have you ever experienced a situation with Claude Code where the rules you defined in CLAUDE.md are followed initially, but start to be ignored toward the end of a long session? I was particularly struggling with projects that had many strict rules in CLAUDE.md. With 10 to 20 clauses like "do not touch this directory" or "use only these specific APIs," having to roll back and review every time Cl...

Why We Started Systemset: Building Smarter Tools for Modern Businesses

Our journey to make work simpler, faster, and growth-driven through smart systems. In today's fast-moving digital world, every business and developer needs the right set of tools to succeed. But there's a problem: Either the right tools don't exist in the market, or if they do, they're too expensive and out of reach for students, small startups, and even independent developers. This is where...

AI Won’t Kill Jobs. It Will Reshape Work Itself

AI Won’t Kill Jobs. It Will Change What “Work” Means The fear feels new. The pattern is not. The fear around AI sounds absolute. Jobs will disappear. Entire careers will collapse. People won’t be needed in the same way. It feels like a clean break from the past. It isn’t. This belief assumes something that has rarely been true. That work disappears in a straight line when...

Multi-Language Code Evaluation Pipeline for LeetCode-Style Problems

Multi-Language Code Evaluation Pipeline for LeetCode Style Problems Most evaluator writeups optimize for speed first. Our biggest quality issue was not latency, it was false negatives. We repeatedly saw “correct-looking” solutions fail across languages due to starter drift, I/O contract mismatch, and comparator inconsistency. So we redesigned the pipeline around one goal: deterministic, expla...

Kubuntu vs KDE Neon: A Technical Deep Dive

For KDE Plasma fans, two Linux distributions frequently come up in discussion: Kubuntu and KDE Neon. They may appear similar - both ship with KDE Plasma as the default desktop, both are based on Ubuntu, and both are friendly to newcomers. But under the hood, they diverge in philosophy, update cadence, and package management. Let's break them down in technical detail. For more developer tools co...

Moving OpenCode Desktop to Electron

I recently announced that we’ve rebuilt OpenCode Desktop on top of Electron and will soon stop releasing the Tauri version. This wasn’t a decision we made lightly, and it has nothing to do with either Tauri or Electron being innately “better” or “faster” - Electron is simply a better fit for our use case. To understand why, let’s first discuss how OpenCode actually works. TypeScript all ...

Week in AI Recap: 7 Shifts That Actually Matter for Indian Developers (April 2026)

I spend my weeks watching AI news for one reason: I automate workflows for Indian businesses, and the ground shifts under my feet every Monday. Most of what trends on X this week isn't useful. A few things are. Here's the signal, filtered for developers in India who ship real work. 1. Agent frameworks are consolidating — pick one and move on The "which agent framework" debate is finall...

Clinic-CoPilot

I built a clinical assistant that could summarize patient notes pretty well. Then I asked it about the same patient two weeks later, and it confidently ignored everything it had already seen. That’s when I realized: I hadn’t built a system. I’d built a stateless loop. What this system actually does Clinical CoPilot is a memory-first system for primary care workflows. It takes raw visit notes ...

Claude Design Looks Like AI Magic. Reading the Source, It's Four Engineering Patterns.

Before the Hype Settles Anthropic shipped Claude Design on April 17, and most of the discussion has framed it as a Figma-challenging AI design tool. I used it differently. Instead of treating it as a design tool, I treated it as a specimen — generated a handful of skill bundles, exported the output, then spent more time reading the source than tweaking the design. I was more interested ...

Originally built by Austrian developer Peter Steinberger as “Clawdbot” (and later Moltbot), it has rapidly evolved into what many are calling the “Linux of Agents.” The viral narratives claim it wi...

The Economic Moat (Quantifying your AI ROI)

This is the surprise "Director's Cut" finale of our "Agentic Readiness" series. We've talked about the "Wall" and the "Tsunami." Today, we talk about the Bottom Line. In the early days of AI coding, the conversation was all about Velocity. "How fast can I ship?" But as we enter the era of millions of lines of AI-generated code, the conversation is shifting to Economics. Forward-thinking e...

If You're Building with LLMs, You Should Have Thought About Observability from Day One

Introduction "AI did something. But I have no idea what it actually did." — Before that happens to you, observability is something you really need to think about upfront. When you develop using AI coding tools like Claude Code or Cursor, you can see "it works." But "why it worked," "where and how it made decisions," and "whether the implementation matches my intent" become much harder ...

The reporting tool gap nobody talks about — and what I'm building to fix it

Every SaaS product eventually gets the same support ticket. "Can I customise the report layout?" "Can I export this with my own columns?" "Can we add a subtotal by region?" And every team picks one of three bad answers. Option 1: Say no. You lose the power user. They switch to the competitor who said yes. Option 2: Use an enterprise reporting tool.

I didn't start by writing code. I started with a simple frustration. Every time I needed to split a PDF, the process felt wrong. Upload file → wait → download → hope nothing breaks. And the bigger issue: Why am I uploading my files at all? That didn't sit right with me, especially when dealing with sensitive files. Some of these PDFs contain sensitive data.
