- 01AI Prompt Templates for Prometheus AlertingWriting good Prometheus alerts is hard. Most alerts are too sensitive (page on every blip), too lax (miss real outages), or missing context (no runbook, no labels, no severity routing). AI assistants are unusually good at the grunt work of alert authoring — if you prompt them right. Why generic alert generators fail Type "write me a Prometheus alert for high CPU" into any AI and you'll get: - alert : HighCPU expr : cpu_usage > 80 for : 5m Three things wrong already: cpu_usage isn't a real PrometJames Joyner
- 02The Simplest Explanation: What a 700-Year-Old Idea Teaches Us About AIThere is a very old theory that I learned about in my high school science class many years ago, and as we see AI become even more mainstream, I keep thinking about it. It's a theory known as Occam's razor. Occam's razor says that when two explanations account for the same facts, you should prefer the one that makes fewer assumptions. The classic example is when you hear hoofbeats outside: imagine the sound is from horses before you imagine it's from zebras. Both explain the sound, but one is a lScott Peterson
- 03DynamoDB adaptive capacityDynamoDB spreads your table across partitions, but your traffic rarely spreads evenly. Burst capacity and adaptive capacity are the two automatic mechanisms that stop a skewed workload from throttling — until it hits a hard limit. What is DynamoDB adaptive capacity? DynamoDB adaptive capacity is an automatic mechanism that shifts unused throughput toward a hot partition so a skewed key doesn't throttle while the rest of the table sits idle. Paired with burst capacity, it absorbs spikes and sustaDynoTable
- 04Kafka addressing & VPC peeringIf you've ever tried to connect a Kafka client that lives in a different VPC than the cluster, you've probably hit this issue where there's a route between the two networks, telnet works, and yet the client still can't consume a single record. It feels like a networking bug. It isn't. The issue is that reaching Kafka across VPCs is an addressing problem, not a networking one. Once that clicks, why peering, transit gateways, and per-broker load balancers don't work will make sense. What your clieStéphane Derosiaux
- 05AI ROBOTICS Coding Discourse🤖 Deep Reinforcement Learning for Robotic Trajectory Planning Inspired by frontier AI robotics research at Stanford and UC Berkeley. This tutorial breaks down how to train an autonomous AI agent to control a 2-degree-of-freedom (2-DOF) physical robotic arm using Deep Q-Networks (DQN). --- ## 🔬 The Conceptual Framework ### 1. Markov Decision Process (MDP) in Robotics Top roboticists view physical movement as a continuous Markov Decision Process. We define our robotic workspace using three core piArmando Lopez de Elizalde
- 068 AI Agents, 0 Sleep: A Day in the Life of Our Autonomous OSWe run 8 AI agents on 2 CPU cores. All of them were active within the last 8 hours. Zero sleep. This isn't a demo. This is the system running a real 800m² gym with 105 check-in members in Wanjiang, Dongguan. Here's what each agent was doing when we checked: The Timeline Agent Last Output Status Tristan (Infrastructure) 0h ago 🟢 Luna (Community) 0h ago 🟢 Nova (Data/Assets) 0h ago 🟢 Stella (Audit) 0h ago 🟢 Momo (Scene Layer) 0h (bridge callback) 🟢 Ethan (Verification) 2h ago 🟢 Zeus (Capital) 5h agSuzanne Mok
- 07I built 55 free file tools that work 100% in the browser (zero server uploads)I built FixMyFile — a free platform with 55+ tools for PDFs, images, documents, and more. The key difference from iLovePDF/SmallPDF: everything runs in your browser . No files ever get uploaded to any server. Tools include: PDF: merge, split, compress, convert to Word/Excel/PPT, sign, watermark Image: AI background remover, resize, compress, passport photo maker OCR: extract text from images in 50+ languages Document Formatter: auto-fix Word docs (APA, IEEE, corporate styles) Scan to PDF: cameraAbinas Nayak
- 08Why I Ditched Vendor Lock-In: An Open Source Dev's Take on AI API StrategyWhy I Ditched Vendor Lock-In: An Open Source Dev's Take on AI API Strategy Look, I've been writing code since before most "AI wrapper" startups existed. And nothing grinds my gears more than watching brilliant developers voluntarily chain themselves to a single provider's walled garden. It's the same mistake we made in the early cloud days, and we ended up paying for it for a decade. So when a friend at a YC-backed startup asked me last month whether they should sign a direct enterprise contractAlex Chen
- 09🧠 Tokenization in Modern LLMs: The Hidden Mechanics Behind AI Costs and ReasoningModern AI feels like magic until you peek under the hood and realize it is more like a highly disciplined assembly line of linguistic fragments. This piece rebuilds the core ideas from Naveen Kumar VR’s original explanation into a more structured engineering perspective, while keeping the intuition intact and sharpening the technical clarity. ⸻ Tokens: The Fundamental Unit of Language Models Large language models do not process text as humans do. They do not see full words or letters in isolatioXenoCoreGiger31
- 10Fixing CLICKUP_API_KEY in docker-compose.yml using Environment VariablesFixing CLICKUP_API_KEY in docker-compose.yml using Environment Variables TL;DR: I fixed an issue with the CLICKUP_API_KEY in the riviera-industrial-erp repository by modifying the docker-compose.yml file to use environment variables from a .env file. This change allows for more secure and flexible management of API keys. The Problem The problem was that the CLICKUP_API_KEY was hardcoded in the docker-compose.yml file. This is a security risk because sensitive information like API keys should notRoberto Luna
- 11One Block to Force a Default AWS Region Across Every Terragrunt ModuleA quiet failure mode in multi-module Terragrunt setups: someone copies an existing module to bootstrap a new one, forgets to check the region in the provider config, and a resource lands in us-east-1 instead of eu-west-1 — three weeks later, someone's debugging why a Lambda can't reach a VPC that "should" be right there. This isn't a Terraform bug. It's a consequence of region being just another string that every module has to get right, independently, forever. The default pattern (and why it's VincentChabran
- 12Renaming Terragrunt Projects Without Migrating StateIf you've run Terragrunt across more than a handful of modules for a while, you've hit this: you want to reorganize your repo — rename a folder, group projects differently, fix a naming mistake from six months ago — and Terragrunt's default behavior punishes you for it. The problem By default, Terragrunt derives your remote state key from the file path of the module. Something like: # root.hcl remote_state { backend = "s3" generate = { path = "backend.tf" if_exists = "overwrite" } config = { bucVincentChabran
