Gnoseed

What it does

You read the docs, pass the tutorial… and forget it in a week. Gnoseed fixes that: 3,000+ practical flashcards & quizzes across 38 decks — Kubernetes, AI/LLMs, DevOps, Security and many more. It applies spaced repetition algorithms (SM-2 or FSRS), so each card returns right before you'd forget it. Guided paths prepare you for popular certifications like CKA, AWS & Terraform Associate. Completely free, zero sign-up — and every card you master grows your skill from seed to bloom.

Learn Kubernetes, AI, Linux, Terraform and more with 5,900+ free online flashcards and quizzes. SM-2 & FSRS spaced repetition, no sign-up, works offline.

Pick a topic, answer a few questions, find out what you actually know. Every card links the doc it came from, and multiple-choice cards explain why each wrong answer is wrong. Four reasons people open Gnoseed . Pick the one that sounds like you. Pick the exam you are sitting. Its deck is split into the same domains as the official exam guide, so you always know which domain you are weak in — and you keep drilling it until you are not. The question appears alone. You answer, then compare against a model answer and the points an interviewer is listening for. No syllabus, nothing to configure. Open it, answer a few, close it. Cards you fumble come back sooner. The decks that didn't exist two…from gnoseed.com

In the maker’s words, at launch

Hi everybody, I created my personal weekend project Gnoseed to learn more about Kubernetes with spaced repetition. Very soon it evolved into a small library of various topics about modern tech stack - AI/LLMs, DevOps, Security, and anything I found interesting. Currently it has 47 decks and ~4000 questions. A…

  Katakate – Dozens of VMs per node for safe code exec2025 · github.com · ▲124

  I've built this to make it easy to host your own infra for lightweight VMs at large scale. Intended for exec of AI-generated code, for CICD runners, or for off-chain AI DApps. Mainly to avoid Docker-in-Docker dangers and mess. Super easy to use with CLI / Python SDK, friendly to AI engs who usually don't like to mess with VM orchestration and networking too much. Defense-in-depth philosophy. Would love to get feedback (and contributors: clear & exciting roadmap!), thx

  Klaw.sh – Kubernetes for AI agentsFeb 2026 · github.com · ▲60

  Hi everyone, I run a generative AI infra company, unified API for 600+ models. Our team started deploying AI agents for our marketing and lead gen ops: content, engagement, analytics across multiple X accounts. OpenClaw worked fine for single agents. But at ~14 agents across 6 accounts, the problem shifted from "how do I build agents" to "how do I manage them." Deployment, monitoring, team isolation, figuring out which agent broke what at 3am. Classic orchestration problem. So I built klaw, modeled on Kubernetes: Clusters — isolated environments per org/project Namespaces — team-level…

  We built a managed Kubernetes provider at half the cost of AWS2023 · symbiosis.host · ▲25

  Since there’s a few discussions recently on $4 VPSes we thought you might be interested in Symbiosis, a cheaper and simpler managed k8s provider. Supported features include external LBs, encrypted+replicated storage and autoscaler. Infrastructure can be managed with UI, CLI, Terraform or Pulumi. Control planes are free of charge and a 1vCPU/2GB node goes for $6 per month. We’re live in Germany right now and we’re expanding into US during 2023. Feel free to try it out and leave a comment.

  KubeForge – A GUI for Kubernetes YAMLs2025 · github.com · ▲62

  Hey HN, I'm Brandon, a solo dev, and I built KubeForge - a visual editor for Kubernetes deployments that helps you build and validate YAML configs. Origin Story: Over the past couple weeks, I got fed up manually writing Kubernetes YAMLs, especially when working with nested structures like containers, env, and volumeMounts. Even small typos or misaligned fields added lost time to broken deploys. So I started hacking together a tool to visualize the structure of Kubernetes objects based on the OpenAPI schema. That prototype quickly turned into a full manifest builder. What KubeForge does: -…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I replaced a $120k bowling center system with $1,600 in ESP32s▲2,935

  I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

  Bento - An entire PowerPoint in one HTML file (edit+view+data+collab)▲1,033

  Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

  Getting GLM 5.2 running on my slow computer▲937

  A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

  OpenSEO▲928

  Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
