Need Truly Secure Digital Storage? The Answer Is Decentralized Storage + Privacy Layer

As our digital footprints expand, our data floats around the internet, unsupervised and unprotected. Cloud storage is a practical solution, but it does not focus on data security. Moreover, you no longer truly own your data. This is the pain point that decentralized storage tries to tackle. But privacy is not automatic, even in decentralized systems. An intentional architecture with privacy-by-des...

Anthropic MCP Design Vulnerability Enables RCE, Threatening AI Supply Chain

Cybersecurity researchers have discovered a critical "by design" weakness in the Model Context Protocol's (MCP) architecture that could pave the way for remote code execution and have a cascading effect on the artificial intelligence (AI) supply chain. "This flaw enables Arbitrary Command Execution (RCE) on any system running a vulnerable MCP implementation, granting attackers direct access to

Ghost vs WordPress in 2026: Which Is Better for Technical Blogs?

Every technical blogger eventually faces this decision: Ghost or WordPress? WordPress powers 43% of the internet and has a plugin for everything. Ghost is the lean, fast alternative that was literally built for publishing. Both can be self-hosted. Both are open source. Both will run a perfectly good technical blog. I chose Ghost for byte-guard.net, and I've been running it in production for two w...

Best Practices in Prompt Engineering for AI Agents in Solidity Smart Contract Auditing

AI doesn’t fail smart contract audits—bad workflows do. Throwing code at an LLM and asking for “bugs” leads to missed exploits. Effective AI auditing requires adversarial prompting, strict context (invariants, roles), structured outputs, and multi-step verification. Combine LLM reasoning with tools like Slither and Foundry, enforce human review, and validate exploits before reporting.

Terra Letters — A Living Atlas of the Places We Love

This is a submission for Weekend Challenge: Earth Day Edition What I Built Terra Letters is a living atlas that lets you drop a pin on any place on Earth — and read what the place says back. The app pulls real planetary data for that exact spot: climate trajectory from 1950 to 2050, species recently observed nearby, an actual bird field recording from the region, current weather, air ...

Why Tracking AI Search Visibility Is Kind of Broken

I thought this would be simple. Run a few prompts in ChatGPT. See if the brand shows up. Done. It isn’t. The first thing that feels off You run a query like: best SEO tools for SaaS You get a list. Cool. Run it again a few minutes later… Different list. Try the same thing in Gemini or Perplexity? Different again. At that point you realise: 👉 there isn’t really a “result” to track This isn...

I compiled Rust to WebAssembly to build a system design simulator that runs entirely in your browser!

I compiled Rust to WebAssembly to build a system design simulator that runs entirely in your browser!

Static diagrams don't fail. Systems do. That was the problem I kept running into when practicing system design. I'd draw boxes and arrows, convince myself the architecture was solid, and then an interviewer would ask "what happens to your read traffic if the cache goes down?" - and I'd be narrating from memory, not from evidence. I wanted to watch my architecture break. So I built SysSimulator -...

2000 modules to render a button. Web dev earned this reputation.

A viral thread just asked developers what feels over-engineered in modern web dev. The answers hit like a group therapy session nobody knew they needed. Thousands of comments. The loudest ones all circled the same absurdity: we're compiling thousands of modules to ship a button that says "Submit." And honestly? Nobody could argue back.

Why Random UUIDs are Killing Your Database Performance

Every developer starts with a UUID. It’s the industry standard for a reason: zero coordination, zero DB checks, and zero single point of failure. Any machine can generate one and be 100% sure it’s unique. But as your system scales, that "standard" choice starts to hurt. The Problem: UUIDs vs. Databases If you're using UUID v4 (completely random), you're essentially handing your databa...

Background Tasks: The One Actor in the Codebase and the SIGTERM Bug That Only Broke on Linux

Our agent can plan multi-step work with a persistent task DAG, compress its own memory, delegate to subagents, and load skills on demand — all driven by the same agent loop from the first guide. But every tool call still blocks. When the model calls bash to run a test suite that takes two minutes, the loop sits idle, waiting for the process to finish before it can do anything else. If someone asks...

Pricing engines don’t fail because of bad models—they fail because of weak infrastructure. This guide shows how to build a resilient, low-latency system using Redis Streams for ingestion, a guarded ML microservice for pricing, and Redis cache for fast delivery. It also covers handling market spikes with circuit breakers and safely rolling out new models using shadow mode—so your system stays accur...
