There is a theory that moon was constructed from Thea planet impact with young Earth. Thats a simulation of that episode of Solar system:)
I will take a look on Safari, thanks for the feedback.
Wow, really easy to create server. For how long is it stayed active?
Hmm, probably its better to use yaml or something more token optimized. That output graph for large projects could eat a lot of tokens, I guess.
It was a fun to participate in development. Looking forward what people will say:)

Hey I'm Victor! My team and I built CentralMind Getaway just recently, an open-source tool that auto-generates secure and AI-optimized APIs from structured data. It's for those who don't want to expose direct SQL access to their databases to AI-Agents and spend time building these APIs manually.

What it does: - Auto-generates APIs from your database schema & sample data using AI

- Filters out PII and sensitive data for compliance (GDPR, SOC 2, etc.)

- Optimized for AI with extra meta information for REST and MCP support

- Works with PostgreSQL, MySQL, ClickHouse, Snowflake, BiqQuery

- Bunch of plugins: Telemetry, Auth, Caching, RLS and others

- Deployable via binary, Docker, or Helm

Check it out and please share your thoughts!

- Interactive Demo (GitHub needed): https://codespaces.new/centralmind/sample_databases

- GitHub: https://github.com/centralmind/gateway

- Docs: https://docs.centralmind.ai/

Show HN: Open-Source tool for automatic MCP API on top of your database for LLMs

https://github.com/centralmind/gateway

We’re building an open-source tool that makes it easy to expose secure, LLM-optimized APIs on top of your structured data—without manually designing endpoints or worrying about compliance.AI agents and LLM-powered applications need structured access to data, but traditional APIs and databases weren’t built with AI workloads in mind. Our tool automatically generates APIs that:- Filter out PII...

Re:How I write code using Cursor: A review on Tuesday October 29, 2024 @07:37AM (#41982820)
Using ChatGPT and AI assistants over the past year, here are my best use cases:

- Generating wrappers and simple CRUD APIs on top of database tables, provided only with a DDL of the tables.

- Optimizing SQL queries and schemas, especially for less familiar SQL dialects—extremely effective.

- Generating Swagger comments for API methods. Joyness

- Re-creating classes or components based on similar classes, especially with Next.js, where the component mechanics often make this necessary.

- Creating utility methods for data conversion or mapping between different formats or structures.

- Assisting with CSS and the intricacies of HTML for styling.

- GPT4 o1 is significantly better at handling more complex scenarios in creation and refactoring.

Current challenges based on my experience:

- LLM lacks critical thinking; they tend to accommodate the user’s input even if the question is flawed or lacks a valid answer.

- There’s a substantial lack of context in most cases. LLMs should integrate deeper with data sampling capabilities or, ideally, support real-time debugging context.

- Challenging to use in large projects due to limited awareness of project structure and dependencies.

Hey Hey,

We're curious about your thoughts on Snowflake and the idea of an open-source alternative. Developing such a solution would require significant resources, but there might be an existing in-house project somewhere that could be open-sourced, who knows.

Could you spare a few minutes to fill out a short 10-question survey and share your experiences and insights about Snowflake? As a thank you, we have a few $50 Amazon gift cards that we will randomly share with those who complete the survey.

Thanks in advance

Hi I'm Victor, the developer of CloudPrice.net. Over the last 8 months, we've worked hardly to expand our former site, AzurePrice.net, to also support AWS and GCP instances. I would greatly appreciate feedback from the community on what is good or what else might be missing.Below is a quick list of main features that we have:- Single view of all savings options - Metadata about Azure, AWS, GCP...

As per next steps: We plan to test multimodal ChatGPT with image data, perhaps passing the full screenshot of a dashboard with different charts, to improve the model's contextual understanding. As the main constraint when implementing with raw data is the prompt length, data displayed in a visual format may be more condensed and compact.

Re:ClickHouse Cloud is now in Public Beta on Tuesday October 04, 2022 @07:44PM (#33088802)
Why are you using 'threads' instead of vcpus or aws instances like it was for other benchmarks? Thats really hard to compare and add suspicions here.
Could you share a list of them?
We built a Managed ClickHouse service to help exactly these difficulties with that technology. We are handling sharding, clustering, zookeeper, patching, updates without downtime, and Hybrid storage based on S3. https://double.cloud
Re: on Monday May 30, 2022 @02:06PM (#31561790)
Great question! 1. We tried to build a platform covering end-to-end analytics scenarios with core services based on open-source, and Kafka is an essential block in such solutions. 2. Using them on the same platform eliminates things like traffic between accounts and traffic between AZs and solves security concerns. 3. We are also adding things that help integrate each of these blocks and help users to start using open-source technologies faster.

CDC is our secrete and currently free feature:)
Re: on Monday May 30, 2022 @01:44PM (#31561523)
Sure, we built it with "bells and whistles": Tools for visualization with native support for ClickHouse, lightweight ETL service, and many other things like backups, monitoring, and logs. We even support ClickHouse over S3 when data could be decoupled from computing to S3, giving a performance of Clickhouse and cost of S3 storage.

Re:YDB – An open-source Distributed SQL Database on Tuesday April 19, 2022 @08:06PM (#31091082)
That's something similar to DynamoDB and CosmosDB. I believe the workaround is to have paging on client side to fetch all results.
