How I Deployed Hermes Agent on AWS

My EC2 instance has a public IP address. It has zero inbound firewall rules. And yet I can reach my AI agent from my phone on Telegram, pull up a full web workspace in my browser, and run shell commands on it — all without opening a single port, without a VPN, and without SSH. The latest version also splits storage deliberately: persistent agent data stays on EFS, while the Hermes install and Python venv moved to the root EBS volume. That change keeps pip install / hermes update I/O off E...

超越沙箱:为 AI Agent 构建持久化运行时

http://www.youtube.com/watch?v=WFyFCFC15dE 这篇演讲的题目是 《Beyond Sandboxes: Architecting Durable Runtimes for AI Agents》(超越沙箱:为 AI Agent 构建持久化运行时) ,演讲者是 Orkes 的联合创始人兼 CTO Virein Baraiya 。 演讲的核心观点是: 在生产环境中运行 AI Agent,仅仅依靠“沙箱(Sandbox)”来实现隔离和保护是不够的,更需要一个“持久化运行时(Durable Runtime)”来保证 Agent 的状态可持久化、崩溃后可恢复、过程可审计。 以下是演讲的核心内容总结: 一、 核心痛点:为什么传统的“沙箱”和“内存循环”不够用? 传统的 Agent 开发通常把 Agent 当作一个在内存循环(LLM in the loop)中运行的实体:LLM 观察状态 $\rightarrow$ 决定调用工具 $\rightarrow$ 更新状态 $\rightarrow$ 继续循...

I'm 18, Self-Taught, and I Built an AI Study App for Nigerian Students — Here's How

When I sat down to build Aveliq, I had one goal: give every Nigerian student access to tools that actually help them study smarter. Not a repackaged ChatGPT wrapper. Not another generic quiz app. Something built specifically for WAEC, JAMB, NECO and Post-UTME — the exams that actually determine the trajectory of millions of Nigerian students every year. My name is George Erubami. I go by GeoCode. I'm 18 years old, self-taught, based in Ibadan, Nigeria. I built Aveliq end to end — frontend, ...

Correlation IDs in ASP.NET Core: A Practical Guide for Backend Engineers

When we build backend systems, especially APIs and microservices, debugging production issues is rarely about reading one log line. A single request may pass through an API Gateway, an authentication service, an order service, a payment service, a message broker, and maybe a background worker. Each component may generate logs. But without a shared identifier, it becomes difficult to understand the full journey of that request. This is where a Correlation ID becomes useful. A Cor...

Is OpusClip’s subscription model becoming a real pain point for creators?

I've been looking into AI tools like OpusClip and trying to understand how creators actually feel about them in practice. From what I see, these tools are powerful, but they often come with subscription pricing, usage limits, and credit-based systems that can become restrictive if you're producing a lot of content. I'm currently exploring an alternative idea: a desktop application that generates clips locally on your computer. The goal would be to give users more control over their data an...

How much does context cost an AI coding agent? grep vs graph vs LSP, measured across 936 runs

In my last post I described graphlens — what it does, how it works — and along the way I casually claimed that an agent "burns tokens grepping around a repo." I gave exactly zero numbers to back that up. This post fixes that. Here are the measurements, the data, and a reproducible harness. Spoiler: the conclusion is not the one I expected going in, and that's the interesting part. TL;DR I took one agent (Claude Code), changed exactly one thing — which MCP server feed...

Sync a mailbox into your own database with Nylas

You want your app to have its own copy of a user's email: to search it fast, run analytics over it, or feed it to a model without hitting the provider on every query. The naive version is a one-time pull that's stale the moment it finishes, because new mail keeps arriving and old mail gets read, moved, and deleted. A real sync is two jobs working together: backfill the history once, then track changes forever after. This post builds that out with the Email API and shows the CLI shortcuts for tes...

Collect client feedback on a website without endless revision rounds

Most revision rounds don't spiral because the client is picky. They spiral because the feedback lost context on the way to you. Here's why that happens, what agencies try, and how to make each note clear enough to fix the first time. Why a round actually spirals A revision round is supposed to be one loop: client looks at the site, says what's off, you fix it, they look again. The trouble is that most of the feedback you get can't be acted on as-is. "The hero feels cramped on ...

Stop building custom wrappers for your ML models.

I spent three days last month building a specialized API wrapper for a simple Scikit-learn model. Not because the logic was hard—it wasn't. Because I wanted Cursor to be able to run inference on our churn prediction data without me having to manually copy-paste JSON results into the chat. It is a classic engineering trap: the 'Integration Tax.' You have a working Modelbit workspace, you have your weights deployed, and you have an AI agent that could theoretically use it. But instead of using ...

Exit intent that works on mobile, not just desktop

Originally published on my site, arafatcro.dev/guides . You copy the exit-intent snippet, it fires nicely when the cursor heads for the close button, and you ship. Then you check the data and half your traffic never triggered it, because they were on phones and a phone has no cursor to chase. Exit intent is not one trick. It is a different signal on each device, fired once, and built so it does not become the thing people leave over. The trick everyone copies The standard s...

The 1.4 Seconds That Weren't on Any Span

On the morning of June 3rd, a customer on a live call sat through 1.4 seconds of dead air after she finished a sentence, long enough that she said "hello?" before the agent answered. I had the trace open in Honeycomb forty seconds later. Every span was green. End-to-end p95 read 980ms, comfortably under our budget, and not one span in that waterfall was longer than 400ms. The dashboard told me everything was fine while the customer was, in fact, talking to silence. TL;DR: End-to-end voice l...

Hub-and-spoke SEO for comparison pages — fielding "alternative" search intent from multiple angles

The WordPress maintenance space has several decade-old incumbents — ManageWP, MainWP, WP Umbrella, InfiniteWP. Building a new entrant means inevitably fielding queries like " ManageWP alternative " and " WordPress maintenance tools comparison " — search intent that names a competitor or the category itself. To handle that intent carefully, the LP runs a hub-and-spoke comparison structure . Here's how it's built and why. What hub-and-spoke means A hub-and-spoke pattern places ...

Mobile Coding Is No Longer About Writing Code on Your Phone

AI coding agents have changed software development from a synchronous activity into a long-running workflow that occasionally requires human input. Instead of coding directly on a phone, developers can use mobile devices as control surfaces for monitoring, reviewing, and approving work happening on their own machines. Sesori is designed around this idea, acting as a mobile companion for OpenCode rather than a mobile IDE.

AI Doesn't Have a Data Problem—It Has a Decision Problem

Enterprises have spent years building data platforms and analytics systems, but many still struggle to turn insights into timely action. A new category, Decision Intelligence, combines real-time data, predictive models, AI agents, governance, and automation to shorten the distance between observation and execution. As AI matures, competitive advantage will come less from collecting information and more from making high-quality decisions faster.

How to Secure a Self-Hosted CI/CD Runner on a VPS Without Turning It Into a Backdoor

A self-hosted CI/CD runner on a VPS should be treated like part of your production delivery chain, not just a build machine. Before using it, harden the server, disable risky SSH access, limit inbound traffic, isolate runners by trust level, keep secrets out of the VPS, avoid giving Docker jobs excessive privileges, monitor disk/CPU/memory, plan Docker cleanup, and document recovery steps. The core rule is simple: never let untrusted code run on a runner that can access production secrets or inf...

How We Built a Per-Plant CO2 Dataset for 4,551 Power Stations Worldwide

The authors built and openly published a dataset covering 4,551 power stations worldwide, combining emissions, ownership, capacity, fuel type, and climate-zone data into a single schema. The project's central finding is that only about 15% of plant-level emissions data comes from direct measurements, while the remaining 85% relies on modelled estimates, making provenance and transparency critical for anyone working with emissions datasets.

The Hormuz Disruption Is an Ecommerce Problem, Not Just a Logistics One

A routine beauty purchase became a lesson in how global supply chain disruptions affect everyday consumers. While the Strait of Hormuz crisis created genuine shipping delays and inventory challenges, the article argues that the bigger problem for ecommerce brands is poor communication. Customers are often willing to wait longer for products if they're given clear delivery expectations instead of vague warnings that create uncertainty and drive cart abandonment.
