1. Show HN: LLM Applications from Yml Files
URL: https://github.com/octopus2023-inc/gensphere
Author: octopus2023inc
Description: You build LLM applications with YAML files, that define an execution graph. Nodes can be either LLM API calls, regular function executions or other graphs themselves. Because you can nest graphs easily, building complex applications is not an issue, but at the same time you don’t lose control. The YAML basically states what are the tasks that need to be done and how they connect. Other than that, you only write individual python functions to be called during the execution. No new classes and abstractions to learn.

3. Show HN: I made a site to generate consistent text every time with AI
URL: https://sloap.co/
Author: sasmitharodrigo
Description: Hi everyone! I’m Sas, the founder of Sloap.
A little backstory on why I built this tool: I used to be an Etsy seller, and one challenge I kept running into was using ChatGPT to generate product titles, descriptions, and tags for Etsy product listings. At first, it worked well enough, but after a while, I found myself having to repeat the same instructions over and over. It became time-consuming and, honestly, a bit messy.
That’s when I started thinking, “What if there was a tool where I could set all my preferences once and get consistent, accurate content every time?” I had this idea floating around for a few months, but then something unexpected happened—I got banned from Etsy. That was the push I needed to bring Sloap to life.
Sloap isn’t just for Etsy or e-commerce sellers; it’s designed for anyone who wants consistent content generation without the hassle of repeating instructions. Whether you’re managing social media content, writing blog posts, creating product descriptions for a Shopify store, or generating text for newsletters, Sloap has you covered. It lets you set predefined rules for each project, ensuring your content is always on brand, no matter the platform.
After months of trial and error, learning, and lots of coffee, I’ve finally built something I’m genuinely proud of. It might not be perfect (yet), but Sloap is already so much more than I originally imagined. I’ll keep improving it, adding features, and making it even better with your feedback. Thanks for checking it out, and I’d love to hear what you think!

9. Show HN: Firecrawl-Simple – Stable fork of Firecrawl optimized for self-hosting
URL: https://github.com/devflowinc/firecrawl-simple
Author: skeptrune
Description: Firecrawl Simple is a stripped down and stable version of firecrawl optimized for self-hosting and ease of contribution.
The upstream firecrawl repo contains the following blurb:
>This repository is in development, and we’re still integrating custom modules into the mono repo. It’s not fully ready for self-hosted deployment yet, but you can run it locally.
Firecrawl’s API surface and general functionality were ideal for our Trieve sitesearch product, but we needed a version ready for self-hosting that was easy to contribute to and scale on Kubernetes. Therefore, we decided to fork and begin maintaining a stripped down, stable version.
Fire-engine, Firecrawl’s solution for anti-bot pages, being closed source is the biggest deal breaker requiring us to maintain this fork. Further, our purposes not requiring the SaaS and AI dependencies also pushes our use-case far enough away from Firecrawl’s current mission that it doesn’t seem like merging into the upstream is viable at this time.

10. Show HN: Im Building LimeJourney-Yet Another Open Source Customer.io Alternative
URL: https://www.limejourney.com/
Author: flyingsky
Description: Hello HN - I’m Tobi and I am building LimeJourney. LimeJourney is an open source customer engagement platform, a Customer.io /braze etc alternative.
- For the past few weeks I have been hacking on LimeJourney during my free time and I’m inviting you to check it out and give your feedback. You can try out the demo with email and password [email protected]/[email protected]
- My Grand thesis for building LimeJourney is that the channels through which we currently receive notifications will not be changing anytime soon but with the increase in data - now more than ever - businesses that will catch the attention of customers are the ones who in some shape or form are intelligently sending notifications(possibly with AI).
- LimeJourney in its current form is very far off from what I hope for it to be but still solves a couple of issues I experienced when working on another project. LimeJourney is relatively cheap($50) - single base plan compared to the other big guys in the market(>$100). It is also open source and I’lld love to see folks who are able to, adopt and self host limeJourney. LimeJourney aims to play real nice with whatever you current email sending stack is and we already have integrations with Resend, AWS and are building more.
The codebase is on Github => https://github.com/LimeJourney/limeJourney
Thank you for checking this out. You can reach me at [email protected]

14. Show HN: Remy – an AI agent that finds the best clips from the world’s videos
Author: yungtriggz
Description: Remy is an AI agent that finds you the best clips from the world’s videos in real time.
The Problem:
Remy was born out of a simple frustration I had: after taking the Gordon Ramsay Masterclass, I realised I had already seen most of the content scattered across different YouTube videos over the years.
However, after going back to scouring YouTube to compile all of the videos I was interested in, I found that most of what I was looking for was buried in much longer videos. So, the question became: Why isn’t there one place to find every clip I’m looking for, no matter what video it’s hidden in? From that, Remy began to take shape.
The Solution:
We’ve since developed fast, powerful video search and understanding models, designed to save you time and effort by finding you exactly what you asked for, no matter how niche or specific. Remy searches across billions of videos in seconds, letting you iterate and hone in on the clips that matter most to you.
With real-time clipping, Remy looks for the best clips for your search every time, not just the closest clip we have.
How Remy Works:
Clipping long-form videos into short-form content isn’t new—tools like Opus, Klap, and Veed.io have helped creators do this for years. However, the clips that creators select to maximise engagement often don’t align with what you’re specifically looking for - but the content you want is still in those videos! We’re introducing consumer-focused clipping, tailored to what you want to see, for the first time.
Remy combines a chat interface with our video search engine. Just tell Remy what you’re looking for—whether it’s a specific person discussing something, a topic, or a comparison—and it will pull up the precise moments you asked for, from YouTube videos, interviews, podcasts, etc.
The result? A seamless experience where you’re only watching what interests you, and finding it in a fraction of the time.
Why Remy is Different:
I know, chatbots are feeling a little overdone - but sometimes they can be useful and we think that’s the case here. Remy’s chatbot form combines conversational and iterative search, powering focused rabbit-holes.
Remy doesn’t just search over an index of videos that we maintain, it also has web search capabilities to get the most up to date videos as well. We use Remy to ask questions about changes in San Francisco politics, recent sports games, and new music that’s coming out.
As your searches evolve, Remy understands the context and narrows down results in real time, finding clips that otherwise might be buried deep within hours-long videos. Have questions about a clip it found? Just ask in the chat and get answers rooted in the content Remy found for you.
Some Of Our Favourite Queries:
“The history of Le Gavroche and the Roux brothers.” “Stories about the writing of The Lord of the Rings” “Tell me about a sea animal I probably didn’t know existed”
What You Can Do with Remy:
Catch up on current events - “What’s going on around the world today?” Explore personal stories - “Gordon Ramsay talking about his relationship with Marco Pierre White.” or “Mark Zuckerberg talking about the impact of social media influencers” Make product comparisons - “Show me the differences between Oncloud Ultra 2s and Hoka Speedgoat 6s … Show me people just talking about the pros of the Hokas over the Onclouds … Now just people talking about the tread pattern of the Hokas.” Trace artistic influences - “How did A.G. Cook influence hyperpop?”
The Bottom Line:
Remy finds the exact moments you’re searching for, no matter where they are in a video, or how deep Google’s SEO has hidden them. Spend less time sifting through content and more time getting to the clips that really matter. With Remy, the perfect clip is just a chat away.
Try it out and let us know what you think! Thanks

15. Show HN: Create GitHub issues from voice memo and LLM
URL: #
Author: simplecto
Description: Hey HN!
I’m working on some early demos that will support much better async communication for Developers, Engineering Managers, and Product people.
We are all too familiar with the empty tickets that were used more as breadcrumbs rather than actual context, criteria, and purpose for getting work done.
I want to solve that as well as help non-technical product managers be able to give sufficient context to developers / EMs when making picking from the backlog or prioritizing.
This is a short demo of the workflow and I welcome your feedback.

17. Show HN: Melchi – Open-Source Snowflake to DuckDB Replication with CDC Support
URL: https://github.com/ryanwith/melchi
Author: ryanwaldorf
Description: Hey hacker news! I built Melchi, an open-source tool that handles Snowflake to DuckDB replication with proper CDC support. I’d love your feedback on the approach and potential use cases.
Why I built it: When I worked at Redshift I saw two common scenarios that were painfully difficult to solve: Teams needed to query and join data from other organizations’ Snowflake instances with their own data stored in different warehouse types, or they wanted to experiment with different warehouse technologies but the overhead of building and maintaining data pipelines was too high. With DuckDB’s growing popularity for local analytics, I built this to make warehouse-to-warehouse data movement simpler.
How it works:
- Supports three CDC strategies: standard streams (full change tracking), append-only streams (insert-only tables), and full refresh
- Handles schema matching and type conversion automatically
- Manages all the change tracking metadata
- Uses DataFrames for efficient data movement instead of CSV dumps
- Provides transactional consistency with automatic rollback on failures
- Processes data in configurable batch sizes for memory efficiency
Quick setup example:
source:
type: snowflake
account: ${SNOWFLAKE_ACCOUNT}
warehouse: YOUR_WAREHOUSE
change_tracking_schema: streams<p>target:
type: duckdb
database: output/local.duckdb
*Current limitations:* * Geography/Geometry columns not supported with standard streams (Snowflake limitation) * Primary keys must be defined in Snowflake (or a row ID will be auto-generated) * All tables must be replaced together when modifying transfer configuration * Cannot replicate tables with identical schema/column names into DuckDB, even from different Snowflake databases
*Questions for the community:* 1. What use cases do you see for this kind of tool? 2. What features would make this more useful for your workflow? 3. Any concerns about the approach to CDC? 4. What other source/target databases would be valuable to support?

18. Show HN: Building a Russian Election Interference Knowledge Graph
URL: https://blog.getzep.com/building-a-russian-election-interference-knowledge-graph/
Author: roseway4
Description: Hi HN, we’re Jack and Daniel from Zep. Last week, we launched a Knowledge Graph-based visual exploration tool and AI assistant to analyze Russian election interference in the run-up to today’s US elections. This article is a deep dive into how we built the Knowledge Graph and Explorer using ~60 sources (equivalent to 6 million input tokens), LangGraph, FastHTML, sigma.js, and Graphiti, Zep’s open-source temporal Knowledge Graph library.
We detail several challenges we faced and how we addressed them:
- Graph quality and our approach to data cleaning and chunking;
- Solving for (somewhat successfully) LLM bias, hallucination, and confused causality. All significant concerns given the use case.
Explorer: https://russia-elections24.getzep.com/
Tech deep dive: https://blog.getzep.com/building-a-russian-election-interfer…
Launch post: https://blog.getzep.com/russian-influence-operations-graph/
Some interesting findings and insights from the data:
- Extensive use of GenAI: for example, Russia’s Bad Grammar operation targeted Ukraine, Moldova, the Baltic States, and the United States with AI-generated content on themes of immigration, corruption, and Ukraine.
- International breadth: Hosting and DNS, sock puppet social media accounts, content creation, and administration services were sourced from many countries, including Malaysia, Bangladesh, Vietnam, Finland, Israel, and Lithuania (and Wyoming!).
- Theoretical underpinnings: We see and read about the tactics of Russian state operations, sometimes professional, sometimes ham-fisted. However, a sophisticated military-political strategy provides the theoretical foundation beneath these visible activities (ask the assistant about the Matryoshka Model and Gerasimov Doctrine).

19. Show HN: Whirlwind – Async concurrent hashmap for Rust
URL: https://github.com/fortress-build/whirlwind
Author: willothy
Description: Hey HN, this is Will and David from Fortress (https://news.ycombinator.com/item?id=41426998).
We use a lot of async Rust internally, and created this library out of a need for an async-aware concurrent hashmap since there weren’t many available in the Rust ecosystem.
Whirlwind is a sharded HashMap with a fully asynchronous API. Just as dashmap is a replacement for std::sync::RwLock<HashMap>, whirlwind aims to be a replacement for tokio::sync::RwLock<HashMap>. It has a similar design and performance characteristics to dashmap, but seems to perform better in read-heavy workloads with tokio’s green threading.
Benchmarks are in the readme! We used an asyncified version of dashmap’s benchmark suite. The project is in a pretty early stage and I’m sure there are flaws, but I’m pretty happy with the performance.
There is some unsafe involved, but we run Miri in ci to (hopefully) catch undefined behavior well before it’s in an actual release.
We’d appreciate any feedback! Thanks in advance :)

20. Show HN: Capd – idea to visually analyze active PowerShell with OpenAI Vision
URL: https://github.com/Lywald/CommandCapd
Author: anon012012
Description: I’m not sure you’ll find that useful but the point is to debug last-displayed error messages no matter where they come from, and without scanning textually (not even sure it can be done textually). Don’t forget to insert your API key in the py file.
Here’s what GPT says about the idea:
“Using OpenAI’s vision capabilities to scan a PowerShell window and generate prompts for troubleshooting error messages is an innovative idea and could be helpful for diagnosing issues, especially if you have frequent and complex PowerShell scripts. This could allow for quick, contextual recommendations based on the exact error text or code provided.”
Sounds good to me

24. Show HN: NewsCatcher’s Hyperlocal News API – Granular City-Level News Feeds
URL: #
Author: kizy25
Description: We’ve launched NewsCatcher’s Hyperlocal News API to provide city-level news feeds for market analysis, localized apps, and data analytics.
Why We Built It:
Aggregating hyperlocal news is complex. Local news comes from diverse sources, many covering national topics, making it hard to isolate local events like transit updates, crime, extreme weather alerts, or infrastructure projects. Searching by location alone can lead to irrelevant results, especially with city names that overlap or match common words (e.g., Orange, Lake).
What It Does:
Our API provides precise, location-based news by processing 185K articles daily and tagging each with its associated_town down to the town level with 92% accuracy. Covering 31,000 U.S. locations, it uses advanced NLP to accurately associate location names, even when they’re common words.
It enables you to:
- Access near-real-time, location-focused news feeds
- Filter by topic (e.g., crime, sports), keyword, and date
- Cluster articles covering similar events and topics
- Get sentiment score for a headline and article body
- Recognize and extract entities
Key Features:
- AI-powered location recognition and validation
- Advanced querying with boolean operators and proximity search
- Multiple town association methods for precise location matching
- NLP-enriched content for deeper analysis
- Articles clustering
- Multi-language support
- High volume data retrieval (up to 1000 articles per request)
For a demo, try our 15 public RSS feeds: https://www.newscatcherapi.com/local-news/rss/. The API provides JSON output for easy integration.
Tech Specs:
- RESTful, JSON-based API
- API key authentication
- Scalable for high-volume queries
We’d appreciate any feedback or questions on use cases.

Author: fluidwizard
Description: Hey HN, this is a small project myself and closer friends have been building on our free time (https://github.com/Dr-Nekoma/lyceum), it finally reached 0.1.0, we are open to feedback!
The original idea was to experiment with Zig + Raylib, eventually we wrote a small server in Erlang as well. We started by first interacting with Erlang via its C bindings, but this eventually led to some of us to prototyping our own tooling to better integrate Zig types with Erlang, we called such tool “zerl” as its avaliable here https://github.com/dont-rely-on-nulls/zerl.
Most of the developers are NixOS users, so the tooling heavily relies on Nix as well, including a Postgres running our devshell as well.

31. Show HN: I wrote an open-source browser alternative for Computer Use for any LLM
URL: https://github.com/gregpr07/browser-use
Author: gregpr07
Description: Hey HN,
I made Browser-Use, an open-source tool that lets (all Langchain supported) LLMs execute tasks directly in the browser just with function calling.
It allows you to build agents that interact with web elements using natural language prompts. We created a layer that simplifies website interaction for LLMs by extracting xPaths and interactive elements like buttons and input fields (and other fancy things). This enables you to design custom web automation and scraping functions without manual inspection through DevTools.
Hasn’t this been done a lot of times? Good question, as a general SaaS tool yes, but I think a lot of people are going to try to make their own web automation agents from scratch, so the idea is to provide groundwork/library for the hard part so that not everyone has to repeat these steps:
- parse html in a LLM friendly way (clickable items + screenshots)
- provide a nice function calls for everything inside the browser
- create reusable agent classes
What this is NOT? An all knowing AI agent that can solve all your problems.
The vision: create repeatable tasks on the web just by prompting your agent and not care about the hows.
To better showcase the power of text extraction we made a few demos such as:
- Applying for multiple software engineering jobs in San Francisco
- Opening new tabs to search for images of Albert Einstein, Oprah Winfrey, and Steve Jobs
- Finding the cheapest one-way flight from London to Kyrgyzstan for December 25th
I’d be interested in feedback on how this tool fits into your automation workflows. Try it out and let me know how it performs on your end.

URL: https://www.perfroute.com
Author: maurodelazeri
Description: Hi HN! I built PerfRoute because I was frustrated with monitoring tools that either required complex integration or provided shallow insights. Here’s what makes it different: Our core is a distributed network of agents across cloud providers. Each agent:
* Automatically collects DNS metrics, SSL status, and geolocation data
- Uses an isolated V8 engine to run custom evaluation logic
- Can perform full MTR analysis (optional, takes 10-15s for accuracy)
- Adapts automatically to identify network path anomalies
Technical implementation:
* Agents run in isolated environments with independent networking stacks
- Custom JavaScript evaluation runs in V8 isolates for security
- Dynamic baseline learning for network path detection
- Automatic correlation of path changes with performance impacts
- Zero-config SSL and DNS monitoring baked into every check
You can try it right now:
Visit https://www.perfroute.com/ Enter any endpoint See immediate global results
Here a video of it: https://www.youtube.com/watch?v=fxAhu1aHaRU
I’ll here here to discuss the technical details and answer questions about the implementation. Particularly interested in hearing about:
* What monitoring edge cases are you struggling with?
* What network metrics would you find most valuable?

38. Show HN: A free multiviewer to watch major news events like elections
Author: MattieTK
Description: Hey HN!
I’m a Product Manager at the FT in the UK, and VidGrid is something I’ve been working on for years in my own time. It’s just got a major update just in time for the election.
The idea is a way to watch lots of different news streams at the same time, as if you’re in a control room or news gallery for the very latest info. I tried to prioritise usability and speed. All streams are third-party sourced (from broadcaster’s own links).
You can now sign up for an account to save/favourite your own streams, and it has better keyboard and drag and drop support. I’ve also fixed a ton of bugs from the last version.
Happy to answer questions about it, or about news media at this time of year in general!
Enjoy, and have a good evening.

39. Show HN: Tiling Shell – Bringing Modern Window Management to Gnome
URL: https://github.com/domferr/tilingshell
Author: domferr
Description: Hey HN, I’m excited to share Tiling Shell, an open-source GNOME extension I created to bring a more modern, user-friendly window management experience to Linux. Many existing solutions feel outdated and lack in user experience, so my goal with Tiling Shell is to bring a fresh, integrated approach that works well for both newcomers and advanced users.
Demo video: https://youtu.be/RBoO5lgR1kA?t=20 by Omg Ubuntu
Key Features:
- Easily manage, edit, create, and delete custom layouts with a built-in editor.
- Works seamlessly across multiple monitors, even with different scaling factors.
- Provides Windows 11’s snap assistant functionalities, supports keybindings and much more!
I’m excited to keep improving Tiling Shell, adding more customization options and compatibility features. Check it out here: https://extensions.gnome.org/extension/7065/tiling-shell/

40. Show HN: I built a tool that protects your browsing privacy
Author: gdbuildsgd
Description: Hey HN Family,
Long time no see. After the epic failure of my first product (spent 5 months developing it and made $0), I believe this time I’ve built something actually cool.
You know how a remote meeting with your team or a client goes, especially when you have to share your screen. Do I have any tabs with sensitive information? Maybe I didn’t close THAT page. What if the client sees this or that information?
If you are a streamer/content creator, you face similar challenges as well. Let’s say you are shooting a nice YouTube video; but you will have to blur or filter out some sensitive information. Usually you’d deal with that during post-production, and this is such a waste of time.
Well, nevermore.
Blurs is a browser extension that protect your browser privacy while screen sharing, streaming, or browsing, with different filtering options and modes.
You can select any HTML element on a page, and apply one of three different filtering options (Blur, Solid box, Pixels); or just draw a fixed position filter on your page as you wish. The world is your canvas after all ^^
Not sure how it might help you? Using Blurs brings you those benefits:
1. Enhanced privacy: Protect yourself from sharing private or sensitive data during screen sharing and streaming sessions. 2. Save time on post-production: Reduce the need for post-production editing for screen recording and taking screenshots. 3. Complete control over your browser: Gain fine-tuned control over what parts of your browser to blur or filter. 4. Better screen sharing experience: Remove the risk of sharing personal, business, or sensitive information during meetings.
It works on any Chromium-based browser and Firefox, Microsoft Edge approval still pending though .
But, who is it for?
- Professionals in virtual meetings: Blurs can help you prevent accidental information leaks.
- Content creators and streamers: By filtering out unwanted elements, Blurs can minimize the time spent on editing or obscuring sensitive information during post-production.
- Remove workers handling sensitive information: For remote employees or freelancers dealing with sensitive information, Blurs can help keep work data private during video calls or presentations.
- Educators and trainers: Educators sharing learning materials, or educational resources on screen can use Blurs to filter out non-relevant information, protect personal information; providing a cleaner, distraction-free presentation for students.
- Privacy-concerned individuals: Anyone concerned with protecting their browsing privacy can use Blurs to keep their personal details to themselves.
I hope that this finds this tool of mine useful. I am open to all constructive criticism, feedback, and looking forward to hearing about your opinions.
Have a wonderful day <3

41. Show HN: RedisDict
URL: #
Author: Attummm
Description: RedisDict is a Python dictionary with a Redis backend, designed for handling large datasets. It simplifies Redis operations especially for large-scale and distributed systems, and has been running in production since 2017, originally built in Python 2.
The library focuses on get and set operations in Redis, ensuring that each key-value pair operates independently, so changes to one entry do not affect others.
Optimized for performance with large datasets, RedisDict maintains high speed even at scale.
Data types are managed without using Pickle to avoid security risks associated with untrusted, serialized data.
Key features include namespacing, pipelining, expiration, and support for multiple data types. RedisDict provides a full dictionary interface and has extensive test coverage.

Author: sgasser
Description: When working with Claude AI, sharing web content usually requires copying and pasting text or taking screenshots. This extension removes that friction - just paste a URL in your Claude conversation and it automatically extracts and formats the webpage content.
The extension uses Jina.ai Reader for content extraction, preserves document structure, and only activates on claude.ai. No configuration needed, no data storage, fully open source.

URL: https://github.com/darwindarak/rallyup
Author: darwindarak
Description: Hi HN,
I’ve wanted a simple solution to handle Wake-on-LAN sequences for my home and work labs to boot up servers in the right order. I was already dabbling in Rust and thought this would be an interesting project to dive deeper and see if it could work well for this kind of network tool. The result is rallyup.
rallyup lets you set up server dependencies in a YAML file, so each service (e.g., firewalls, storage, VM hosts) comes online in the right order. It verifies each server’s status before moving to the next.
Features:
- Dependency-based WOL with VLAN support
- Built-in health checks (HTTP, open ports, shell commands)
- Lightweight enough to run on a Raspberry Pi or similar device
Would love any feedback. Thanks for taking a look!

URL: https://chromewebstore.google.com/detail/relay-â-intercept-modify/kilmhgoembjiamcmcbecekdonljjiolg
Author: Tammilore
Description: Hey HN,
I recently built an open-source HTTP interceptor called Relay, which works as a Chrome extension for capturing, modifying, and replaying HTTP requests directly in your browser — no account needed.
How it works: Relay lets you capture requests as they happen, modify parameters, headers, or body content, and replay them on the fly. You can customize or debug network requests quickly without needing an external tool or complex setup.
Key features:
- Simple setup: Install the extension and start a session to capture requests. You can filter by URLs and methods.
-Request modification: Make quick edits to any part of the requests for debugging or testing.
- Copy as cURL: Easily copy requests as cURL commands to use elsewhere if needed.
- Replay functionality: Re-run requests with modified data or headers and see the results in your browser.
- Local, no account needed: All interactions are handled locally in your browser, so you maintain privacy and control over your data.
I built Relay to make tasks like testing API integrations, troubleshooting network calls, and experimenting with client-side requests easier. Originally, I made it for myself because I wanted a faster way to look at and edit network requests without constantly switching between my browser and other tools.
After seeing how useful it was, I decided to make it open-source for anyone who would find it useful.
Here’s the GitHub repo: https://git.new/relay
Would love to hear your feedback and suggestions!

52. Show HN: I Made a Oasis AI Minecraft Website, the First AI-Generated Minecraft
URL: https://oasisaiminecraft.com/
Author: yangxiaobo
Description: Hey HN,
Recently, I discovered the first AI-driven video interactive game, where all the visuals and interactive content are generated in real-time by AI based on the user’s actions. To put it simply, it’s like an AI version of Minecraft.
I tried it out, and it is generally playable. However, the graphics are a bit blurry, and sometimes there are minor lags. Overall, there are still some flaws at this stage.
But I feel this is a truly groundbreaking innovation because all the game content is generated by AI in real-time. Therefore, theoretically, each player’s gaming experience is unique, and it’s possible to generate an infinitely large world.
Although the overall experience isn’t yet on par with mainstream games, I think this is a fascinating attempt. In the near future, the gaming industry could be completely revolutionized. Science fiction becoming reality—this might just be the future of ‘Minecraft.‘
I’ve created a website where you can experience the game online and also find some related information about it. I hope this will be helpful to you.
would love your feedback pls.

Author: ArneTR
Description: Eco-CI is an open source plugin that works on many major CI/CD vendors: GitHub, GitLab, Jenkins
It leverages an ML energy model to estimate the power of the current machine executing the pipeline and correlates that with the carbon grid intensity of the public IP.
It then can show directly in the Pull-Request how much energy and carbon is used.
That functionality is paired with an external dashboard that can be hosted which is also free and open source and can show the carbon emissions over time.
Here is an example link where we have for instance been tracking the carbon emissions of Django on GitHub: https://metrics.green-coding.io/ci.html?repo=green-coding-so…
