Sandboxed Code Evaluation for AI-Generated Outputs — How I Built SafeCode Arena

The Problem: Candidate Code Without Trust You're using Cursor, Claude Code, or GitHub Copilot. The AI gives you three implementation options for the same feature. AI: "Here are three approaches: A) Quick but uses unsafe B) Slower but memory-safe C) Balanced tradeoffs" You: "Which one should I ship?" AI: "It depends..." That "it depends" is where responsibility falls through the cracks. Tests tell you if code compiles and passes specs. But they don't tell you abo...

Hacktoberfest 2026: AI belongs to everyone

We have some news we're excited to share today: Major League Hacking (MLH) and DEV are partnering with DigitalOcean to run Hacktoberfest 2026. This October, we’ll host over 300 in-person events (“Fests”) plus a global online event, all about building with open source and open-weight AI. DEV and MLH have supported Hacktoberfest for years under DigitalOcean’s ownership. DEV provided a space to share maintainer and contributor learnings, while MLH has powered both in-person and online events...

I Deliberately Destroyed My Kubernetes Cluster at 2 AM. Here's What Died First.

I Deliberately Destroyed My Kubernetes Cluster at 2 AM. Here's What Died First. Chaos engineering is not about breaking things. It's about discovering that your "production-grade" homelab is held together by hope and a single etcd snapshot before someone else finds out for you. The Setup I was lying in bed at 1:47 AM, staring at the ceiling, unable to sleep. Not because of caffeine. Because of a thought that had been gnawing at me for weeks: If one of my nodes died...

Transactional Email Warmup Explained — 5 Steps for Deliverability and Volume Ramping

Short answer: use a dedicated sending domain, let real transactional demand set the pace of a gradual ramp, and make every receipt request idempotent and auditable before tuning volume. The least complex reliable design is a payment-settled event feeding an outbox, one delivery worker, and a feedback ledger; a synthetic warmup stream adds traffic but does not prove that customers want or engage with the mail. Proof first. Start with the bill because retention can quietly cost more than the...

I Built a Claude Code Skill That Reverse-Engineers Undocumented APIs

I Built a Claude Code Skill That Reverse-Engineers Undocumented APIs Because "the docs are in the code" is not a documentation strategy. The Week I Lost to Grepping I joined a new team last month. Day 1 task: add a feature to the billing service. Day 1 reality: I opened the API docs and realized they were from 2022. Half the routes had been rewritten. The other half never had docs to begin with. So I did what every backend dev does. I grepped. grep -r "app.get|app.post|router."...

LighthouseReckoning: A Lightweight LoRa Mesh Network for Arduino, ESP32 and RP2040

LighthouseReckoning LighthouseReckoning is a lightweight LoRa mesh networking library for Arduino-compatible microcontrollers, currently tested on ESP32 and RP2040 with SX126x LoRa radios. What is LighthouseReckoning? The goal is simple: Sensor → Relay → Relay → Home One node acts as the Home node . Other nodes automatically determine a path toward it. A node does not need to know the entire network topology. Instead, nodes exchange information about t...

S3 Egress Fees: Why Downloading Your Own Data Costs So Much

Cross-posted from the Runsite blog . You put a few hundred gigabytes of images on object storage, glance at the pricing page, and the numbers look friendly: storage is a couple of dollars a month, basically a rounding error. Then the first real invoice arrives and it's a hundred and something. Nothing about how much you're storing changed. The line that blew up isn't storage at all. It's egress — the charge for data leaving the bucket — and it's the part of the bill nobody shops on...

Single-database multi-tenancy in Symfony: a 31-line Doctrine filter, and the five places it never runs

Single-database multi-tenancy is the cheapest kind: one schema, one connection, an organization_id column on every tenant-owned table. The whole design rests on one promise, and it is a promise about forgetting : no developer on the team will ever have to remember to write WHERE organization_id = ? , because forgetting it once leaks another customer's data. Doctrine has had the tool for this for years. It is a SQLFilter , it is about thirty lines, and almost every article about it stops ...

Building Distributed Systems in Elixir: Part 6 — Named Processes

In the previous part of this series, we built a tiny supervisor from scratch. When a worker crashed, the supervisor started a replacement. That replacement had a new PID: old worker -> #PID<0.102.0> new worker -> #PID<0.105.0> This reveals an important limitation of sharing PIDs as a public interface. A PID identifies one running incarnation of a process. It is excellent for sending a reply, setting up a monitor, or creating a link. It is not a stable ad...

Show HN: MCP app for Android, drive apps via AI (no root, PII redacted locally)

Hi HN, author here. Android Remote Control MCP is an MCP server that runs directly on your Android phone (no root, no ADB, no computer in the middle) and lets an AI agent drive real apps the way a human would: it reads the screen through the accessibility tree, taps, types, scrolls, optionally also screenshots. I spent a lot of time optimizing tool usage and token consumption, and making it work not only via local harnesses but also via Claude.ai / Claude Desktop and chatgpt.com (if you have the...

Show HN: Pack AI and scientific models as self-contained boxes

Hi! I've been working on an open-source project called Scrollcase. I started this cause moving Python or ML projects between machines is often painful. You need the right Python version, libraries, native builds, model files, and so on. So instead of making someone rebuild a Python environment on their machine, Scrollcase packages everything once, including Python, locked dependencies, code, and model files. Then they can verify it, unpack it, and run it. No Python install, no pip install, no Do...
