Meet octoscope — your GitHub profile, at a glance, in your terminal

The problem If you work on GitHub every day, you probably know the dance. You're deep in a coding session, you want to glance at "how many PRs are open on my repos right now", or "did that follower count tick up after the release post", or "which of my repos did I last push to". So you tab over to the browser, wait for the page to load, click through to a sub-view, squint at the numbers...

Stdout vs stderr vs stdin

Stdout vs stderr vs stdin

One of the most useful Linux concepts for beginners is understanding the 3 standard streams: · stdin for input · stdout for normal output · stderr for errors Once this clicks, redirection and pipes make a lot more sense. I made this one-image cheat sheet to simplify it.

How I Built GPU-Accelerated Frosted Glass and Acrylic Blur for .NET MAUI (And Why Every Other Library Gets It Wrong)

Blur on Android in MAUI is kind of a mess. I needed a frosted-glass effect over a scrolling message list and everything I tried either stuttered or just looked bad when the content behind it moved. So I dug into how all the existing libraries actually work under the hood. Turns out they're all doing the same thing: Grab a Bitmap of what's behind the view, on the CPU Run a blur pass in software...

184 MCP installs and a 93.9% adversarial signal GPT-4o can't replicate

184 MCP installs in 72 hours after publishing agentoracle-mcp — and more importantly, 93.9% of adversarial-flagged refutations that GPT-4o alone could not catch. This post is about the verification layer under that number: the benchmark methodology, the architecture that produces the adversarial signal, and why claim verification deserves its own layer in the agent stack. The Benchmark ...

🛡️ Lirix v1.3.0: Deterministic Security for AI Agents in the Dark Forest

AI agents + private keys is not innovation. It is operational debt with a liquidation timer. A single hallucination can misprice a swap. A single stale RPC can poison an intent. A single unsafe action can turn a product demo into a post-mortem. That is the problem Lirix was built to solve. Today, we are launching Lirix v1.3.0 — the release that turns Lirix from a simple proxy into a determini...

What is a Raspberry Pi? A Complete Beginner’s Guide

How’s the craic? If you’ve ever heard the term Raspberry Pi and wondered what it actually is, you’re not alone. Despite the playful name, the Raspberry Pi is a serious piece of technology that has changed how people learn programming, build hardware projects, and explore computing. I remember the first time I heard the term Raspberry Pi. I thought it was some weird AI gadget or maybe a tiny...

I built an AI English speaking coach — what was technically hard

I spent the past year building Elispeak, an AI English speaking coach. The user-facing pitch is simple — talk to an AI tutor, get instant pronunciation and fluency feedback, practice TOEFL / IELTS / CELPIP speaking tasks on demand. Under the hood, a few things turned out to be much harder than I expected. This is a note to myself, and to anyone else building voice-first language tools. ...

The Engineering Student’s Secret Weapon: Automating My Research Workflow with OpenClaw

Your MCP server probably has too many tools

I built the first working version of Beacon, Siren's MCP server, in an evening while playing video games. The thing I shipped that night was technically a functioning MCP server, and it was completely unusable. Claude could see the tools. Claude could list the tools. Claude would confidently pick the wrong tool every single time, call it with parameters that didn't match anything real, and then c...

MCP Auth That Actually Works: OAuth for Remote Servers

In the first post I showed what an AI does with 118 MCP tools. In the second I showed how we organized them. Both posts assumed a working connection. This one covers the hardest part: getting that connection to work securely. Most MCP servers run locally. You add a JSON block to your Claude config, paste an API key, and you're done. That works for developer tools. It doesn't work for a SaaS produ...

It didn’t suddenly become slow, unsafe, or obsolete.What changed is that languages like Go — and increasingly Rust — got good enough that raw performance differences are often small, while the cost of building, operating, and maintaining equivalent systems in C...

Why You Should Build Your Own MCP Host: A Python Deep-Dive Into the Agentic Loop

M Models, N Tools, M×N HeadachesEvery integration you build is a form of technical debt, a bill you pay twice. First when you create it, and again every time the system around it shifts. In the fast‑moving world of large language models, that bill grows quickly. With M models and N external tools, you’re suddenly responsible for M×N one‑off connectors, each with its own quirks and maintenance cycl...

How to Prototype Microservices Faster with DSL and Diagrams using Platform90

Microservices become expensive before you even build the real product. You spend time setting up infrastructure, configs, and diagrams instead of solving the actual problem. And most architecture diagrams are outdated before the sprint even ends. This post is about collapsing that gap — using a Domain-Specific Language (DSL) and live architecture diagrams to prototype a working microservice syste...
