How I built an AI platform in a country where the Western ones aren’t for sale

Building Real-World AR: The Brutal Truths After 6 Months of Development

Building Real-World AR: The Brutal Truths After 6 Months of Development Honestly, when I first started building spatial-memory, I thought I was creating some revolutionary app that would change how people interact with their memories. Six months and countless hours later? I've learned more about what doesn't work than what does. And honestly? That's way more valuable. The Drea...

Angular Architecture Patterns That Actually Scale (And When to Use Them)

Introduction Most Angular applications don't collapse because of bad components — they degrade because of architectural entropy. I've seen well-written components sitting inside systems that are fundamentally unscalable: tightly coupled features, services acting as dumping grounds, state scattered across the app, and onboarding that feels like reverse-engineering a legacy system. The co...

Hermes Agent: The Self-Hosted AI That Finally Grew Up. Here's the Two-VPS Setup Under $10.

Last weekend I installed Hermes Agent on two VPS. A brand-new Hostinger box in 1-click Docker. My existing Contabo box via SSH and a single curl command. Same model config on both sides: Sonnet 4.6 as primary, DeepSeek V4 for delegation. Two install philosophies. Both ship a working agent that replies in Telegram within minutes. TL;DR: Two install paths tested end-to-end (zero terminal versus pur...

I got tired of Pomodoro lying to me, so I built a dual-budget desktop timer

Classic Pomodoro has a hidden assumption: once the work timer starts, you should stay focused until it ends. That sounds great in theory. In practice, it kept failing for me. Sometimes I would get distracted in the middle of a focus session. Sometimes other people would interrupt me. The timer kept running anyway, and when those 25 minutes were over, I had no honest idea how much I had actually ...

Subqueries and Cte's

Introduction SQL is a powerful language used for managing and analyzing data. As queries become more complex, tools like subqueries and Common Table Expressions (CTEs) help simplify logic and improve readability. What is a Subquery? A subquery is a query nested inside another query. It is used to perform operations that depend on the result of another query. Example: SELECT name FROM customer...

[x509Lab]Sign new Leaf certificates with your existing Root CA directly in the browser (x509Lab v1.3.0)

Hey everyone. I'm building x509Lab, a purely client-side web tool for visualizing and generating certificate chains. I usually work on this late at night after putting my kid to sleep, so I try to focus on fixing real annoyances I face during my day job. A huge pain point in the previous version was that whenever you hit the Generate button, the app would blindly generate brand new keys and certi...

Hermes 和 OpenClaw，AI Agent 的两条路线之争

如果你最近关注 AI Agent 领域，一定听说过 Hermes Agent 和 OpenClaw 这两个名字。一个是 NousResearch 出品的 Python 原生 Agent，GitHub 星标 10.7 万；另一个是 TypeScript 编写的通用 AI 助手，星标高达 36.1 万，还带着一只醒目的龙虾吉祥物，火遍 GitHub。但用了一段时间之后，我的结论是：这两个项目其实不在同一个赛道。 Hermes Agent 更适合 AI Coding 场景。OpenClaw 更适合通用个人助手场景。这不是一篇"谁更好"的对比文，而是一篇"各有所长"的分析文，从五个维度展开。一、定位与设计哲学 Hermes Agent："The agent that grows with you" Hermes Agent 是 N...

If you've spent any time in the AI agent space lately, you've probably heard of both Hermes Agent and OpenClaw. One is the fast-rising Python agent from NousResearch with 107K+ GitHub stars. The other is the TypeScript-powered personal AI assistant with a staggering 361K stars and a lobster mascot that has taken GitHub by storm.

Your AI Agent Has Your API Keys (And So Does Every Other Agent)

Open your Claude Code settings.json. Look at the env blocks under your MCP servers. Every API key, every database token, every webhook URL you've put there — your agent has all of them, right now, in its process environment. That might sound obvious. You configured it that way. But think about what it actually means. You've got an MCP server for file operations and one for notifications. The not...

Can a P2P on-ramp still work without a platform acting as escrow? In the world of crypto, the first thing a newcomer really has to do to enter the space is usually not trading and not doing DeFi, but completing an on-ramp first. And the on-ramp flow most people are familiar with is usually an OTC exchange on an exchange: the user sends fiat first, and after the platform confirms the pa...
