People are generally amazing at finding use cases for technology that the originators hadn't thought of. I recall being surprised learning about Apache ZooKeeper being used for an …

Quantum computing startups must be excited...

I'd like to think that I get the point of shipping fast rather than getting stuck on making it perfect, but what's the point of shipping something that can make your customer lose …

I don't know much about the LoC use case, but my initial reaction to the post is to ask why they are not building a data lake with open formats. I'm sure there are reasons for disc…

Thanks for catching the point on AI-native access. Previously, operating a Qbeast-backed lakehouse required terminal commands; we've now added MCP connectivity to enable agentic co…

Like seems to be broken, this one worked for me: https://sfstandard.com/opinion/2026/05/06/mythos-cybersecuri...

Qbeast is an efficient, format-agnostic, multi-dimensional clustering engine for the lakehouse, now delivered as a distributed service. Our latest release marks a major milestone: …

At this point, I don't have it clear that this is going to be accepted and adopted. If it is, then it isn't clear what the economic impact will be. Companies still need the job don…

Is that supposed to be the King of Technology or the King of Techno Music?

Has worked fine for me in Spain all day.

>> Does the processes read or propose the value ? It does both, it first proposes by writing a sequential znode and then reads the children (all proposals are written under some pa…

yeah, this is precisely what we do in Apache BookKeeper, and we map N to ack quorums and M to write quorums.

Thanks for your comments, and I'm sorry that you feel that the post does not match your expectation. If you write me directly, I'll be more than happy to clarify any question you m…

Got it, yeah, quorum systems have higher tolerance to tail latency, there is no question about it. we do mention it briefly in the post, but we don't have numbers to show. I'm not …

I'm happy you enjoyed the post and thanks for the comment. If I understand your comment correctly, it isn't the case that the ISR is fixed. The ISR has a minimum size, but it can c…

I'm glad you enjoyed the post. The chain replication work indeed relies on a paxos-based master service for reconfiguration, but I believe that's the only similarity, the replicati…

Thanks for the comment, the vertical paxos reference is indeed relevant here.
