Hey folks!Over the past weeks, I started building a long-term memory for AI agents. While there are many around already, this one is specifically aimed at development teams.There are a few items which make it special: - Development teams can share memories between their agents (and across agent types such as Claude and Codex) - Higher value memories become artifacts, such as code style rules,...

Our CTO Michael Schmidt wrote about our performance optimization methodology at simplyblock.It's an in-depth view onto the technology and technical decisions, as well as how and why running your own storage benchmarks are so important to really understand the performance of your specific workloads.

Thank you very much :)

Happy to get any idea on how to make it even better!

It is complicated to initially wrap your head around, I agree. That's why I thought a demo application is the best way to show that it doesn't have to be super complicated once understood.

Like many things in PG, they aren't always easy to get right away I remember my first time with it years and years ago.

Show HN: Underrated Postgres: Build Multi-Tenancy with Row-Level Security

Utilizing Postgres' RLS feature to isolate user data instead of easy-to-forget where-clauses, is such an underrated use case, I really wonder why not more people use it.If you prefer code over the blog post, I've put the full application example on GitHub. Would love to hear your thoughts.https://github.com/simplyblock/example-rls-invoicing

https://www.simplyblock.io/blog/simplyblock-xata-partnership-next-gen-serverless-postgresql/

Xata, a Postgres platform, and Simplyblock, a NVMe-first storage platform, announced their partnership, bringing the next-gen Serverless Postgres Platform for public/private cloud and on premises installations.While we started the project months ago, now that Databricks acquired Neon, it becomes a new dimension of importance. The future for Neon is quite unknown and there is a good chance that...

It handles authentication on a request basis (which was its own issue just a little while ago): https://www.infoq.com/news/2024/05/aws-empty-s3-bucket-billi...

Not sure I'm really surprised. As far as I know, AWS hasn't been the fastest in resolving issues. I just remember the "S3 Bucket - We Charge You For Unauthorized Requests" issue a few months ago

I guess your biggest issue may be the multiple writer problem, but you'd have the same issue on a local disk. The second multiple writer are supposed to update the same files, you'll run into issues.

Have you thought about TCP sockets between the apps and sharing state, or something like a redis database?

Re:Show HN: Searchable Kubernetes CSI provider listing on Monday June 17, 2024 @01:05AM (#40702481)
You need some type of cluster-wide shared memory?
Re:Show HN: Searchable Kubernetes CSI provider listing on Monday June 17, 2024 @12:13AM (#40702244)
I bet there are lots of mistakes yet. It's a slightly extended list of the csi docs for now. The features mentioned are the features that the docs mention.
Re:Show HN: Searchable Kubernetes CSI provider listing on Monday June 17, 2024 @12:10AM (#40702239)
Simplyblock sponsors the domain, yes. Good point. Should have mentioned that. It's not on the simplyblock github account though.
Re:Show HN: Searchable Kubernetes CSI provider listing on Sunday June 16, 2024 @05:42PM (#40700360)
Guess you want a block storage?
Re:Show HN: Searchable Kubernetes CSI provider listing on Sunday June 16, 2024 @04:10PM (#40699735)
Uh! Thanks for mentioning. Also wasn't aware that plausible is blocked, thanks for the hint, even though I wonder why it breaks the search. I'll figure it out. Thanks again.
