Our of $60B, what does that make VSCode priced at?

Endless, we offer SemQL to query in high-dim space using distance, direction and contrast predicates. It enables anyone to retrieve events that align with a predicate in global vector space.

The fundamental assumptions of distributed systems is having multiple machines that fail independently, communicate over unreliable networks and have no shared clock has the consequence of needing to solve consensus, byzantine faults, ordering, consistency vs. availability and exactly-once delivery.

However, AI agents don't share these problems in the classical sense. Building agents is about context attention, relevance, and information density inside a single ordered buffer. The distributed part is creating an orchestrator that manages these things. At noetive.io we currently work on the context relevance part with our contextual broker Semantik.

Show HN: Semantik, a vector broker that routes by semantic meaning

xer — Tue, 07 Apr 2026 07:47:58 +0000

Hello HN,

Today we are launching Semantik, a message broker that routes by meaning instead of topics. Messages carry embeddings and metadata, and subscribers define what they care about using SemQL, a query language for high-dimensional space. SemQL has three predicates: distance (how similar), direction (messages that align with a concept), and contrast (similar to X but not Y). Semantik behaves like a vector database with a rolling window paired with SQL.

The secret sauce behind openclaw is channels, multiplexing incoming messages into a running LLM conversation. Semantik allows agents to jack into semantic namespaces but only to retrieve information that they care about, skipping the rigid plumbing around traditional message brokers. It solves the issue of "who needs to know" for coordinating between agents.

Feedback greatly appreciated! Reach us using the forms on the webpage.

Lesson learned: If your recovery plan requires calling any API in the dead region — to detach an IP, describe a route table, launch an instance, read an S3 object, or decrypt a volume — it will fail when you need it most.

Every dependency on the primary region is a dependency on the thing that just broke.

This is great! But what if the US invests 1% of GDP in GPU datacenters and then those are not needed becaues someone created a much more efficient architecture?

New comment by xer in "Removing data transfer fees when moving off Google Cloud"

xer — Fri, 12 Jan 2024 10:12:20 +0000

I share the view that nobody avoids an exit or migration because of egress fees. In fact, for online migrations the period of replicating data between providers might go on for months.

But all cloud providers leverage The Principle of data locality or data gravity, which states that compute benefits from being close to the stored data. If a customer moves the data elsewhere it follows that the compute will soon leave too.

New comment by xer in "Spotify will reduce total headcount by approximately 17%"

xer — Mon, 04 Dec 2023 09:22:14 +0000

The elephant in the room: Will Spotify survive the coming wave of generative AI audio content? Wasn't any mentioning on that in the letter.

Seems to me like they would need to ditch a lot of silly investments like original content, platform engineering on Kubernetes and scaled agile which together carry costs in the range of $100s millions, to free up resources to battle new disruptive technologies.

New comment by xer in "Retries – An interactive study of request retry methods"

xer — Thu, 23 Nov 2023 21:43:10 +0000

Correct. It's also the case that human generated requests will lose their relevance within seconds, a quick retry is all it's worth. As for machine generated requests a dead letter queue would make more sense, poor engineered backend services would OOM and well-engineered would load shed, if the requests are queued on the application servers they are doomed to be lost anyway.

I think there is another side to this story which is that referral marketing is having a bad name these days. It's considered fraudulent by many sellers since sometimes these referral sites rank higher than the sellers themselves. I suspect this is part of an effort from Google to put the sellers higher than the referrers in the search results.

xer — Thu, 15 Mar 2018 13:51:01 +0000

From my experience you can increase your luck in life by exposing yourself to more choices. This can be something as simple as having saved up money so you can quit your job whenever you want to. That in turn gives you the "luck" to get a better job if the opportunity presents itself.
