TenkaCloud

What it does

TenkaCloud is an Apache-2.0 platform for hands-on cloud competitions. It provisions isolated environments for each team, supports self-paced Challenges and continuously scored Battles, and brings access, scoring, fault injection, leaderboards, and cleanup into one operator workflow. Start with a no-signup browser quest, run locally with Docker, or host an event on your own AWS account. The open problem catalog and authoring skill let teams create and reuse their own drills.

TenkaCloudは、本物のAWS環境でBattleとChallengeを開催できるOSSのクラウド実戦演習・競技プラットフォームです。チーム別環境、毎分採点、ランキング、問題カタログ、運営画面を提供します。

問題カタログは TenkaCloudChallenge リポジトリで完全に開かれていて、 metadata.json + template.yaml の 2 ファイルを書けば 1 問追加できます。 Claude Code 等のコーディングエージェント向けに 問題作成 skill ( new-problem ) も同梱されているので、 「こういう問題を作りたい」 とアイデアを話すだけで、 初めてでも 1 問が形になります。 社内限定やイベント専用で公開したくない問題は、 Problem Pack を使えばカタログに公開せず、自分のテナントだけに追加できます。 Claude Code や Codex に下のプロンプトを貼り付けると、エージェントが TenkaCloud の説明から「遊ぶ / 立てる」の案内までやってくれます。中身は LLM 向けブリーフィング llms-full.txt です。 Fetch https://tenkacloud.com/llms-full.txt and read it — it is the canonical AI-agent briefing for TenkaCloud. If you cannot fetch URLs, ask me to paste its contents instead. Then, in my language: (1) explain what TenkaCloud is in about five sentences, (2) ask whether I want to PLAY (no AWS…from tenkacloud.com

  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…
