Automating contract intelligence with Doczy.ai™ on AWS
Extracting actionable insights from thousands of contracts and legal documents remains a challenge. For organizations, critical business information is locked in unstructured documents such as contracts, legal agreements, provider arrangements, and vendor invoices. Extracting and operationalizing this information has traditionally been a manual, error-prone, and resource-intensive process. This leads to missed savings opportunities, costly delays, and significant inefficiencies across the enterp
Scaling oncology patient support: How New York Cancer and Blood Specialists transformed customer experience with AWS and Pronetx, now part of Caylent
As one of the United States’ leading oncology and hematology providers, the goal of New York Cancer and Blood Specialists (NYCBS) is to provide comprehensive and compassionate care to patients. The organization handles more than 250,000 patient calls every year across over 100 specialized queues and wanted to optimize its manual call handling process. This post details how NYCBS partnered with Amazon Web Services (AWS) and AWS partner Pronetx (now part of Caylent) to migrate to Amazon Connect Cu
Building a scalable user search layer on top of Amazon Cognito
Imagine a teammate who needs to find a user across thousands of accounts with only a partial email address, a last name, and a known access level. How quickly can your team respond? If your use case involves straightforward searches on standard Amazon Cognito attributes, the built-in ListUsers API is likely all you need. But for advanced scenarios involving custom attributes, fuzzy matching, complex filtering, and sub-second response times, a dedicated search layer is the right investment. Amazo
Ask HN: Any advice on how to learn good software architecture practices?
As someone who picked up coding around the time AI and agents started becoming more mainstream, I realize I don’t have much knowledge about the best way to architect applications, and I often end up going with whatever the agent recommends. I wanted to check with the community: do you have any recommendations on what I should be doing to get better at overall architecture planning?I do ask AI a lot of questions, but it would be good to have a non-AI frame of reference that I can rely on. I find
$100 to a Debian Developer who can get Fresh Editor into Trixie
I use Debian 13 in a regulated industry and I'm teaching people how to code in the context of large projects and TUI.I want to use Fresh Editor (https://getfresh.dev/). This is because Fresh is easier to learn quickly than vim & emacs, and more of an IDE than micro & nano, and more favorable for compliance auditing because of its core-and-plugins architecture and open source code using Rust.I would like to donate toward this goal. I can afford to offer $100 to any Deb

Bill Gates AI on AI (one month later)
# The Agentic Tidal Wave*To:* Executive Staff and Direct Reports
*From:* Bill Gates
*Date:* April 26, 2026Our vision for the last 20 years can be summarized in a succinct way. We saw that exponential improvements in cloud would make great software quite available. In the next 20 years the improvement in computer power will be outpaced by the exponential improvements in autonomous expert systems. Verifiable trust will be crucial to delivering the benefits of these advances.Most users of software
Show HN: Chunk sidecars for validating agent-generated code before pushing to CI
Hi HN! My name is Olaf, I work at CircleCI as a technology advisor in the CTO office, came in through the acquisition of my company Vamp.io (progressive delivery for microservices on k8s) in 2021. Wanted to hear the HN community feedback and thoughts on a project we think could be very interesting when adding AI coding agents to the SDLC and your CI pipelines.Our team at CircleCI built Chunk sidecars after repeatedly running into the same issue internally: by the time our CI catches a failure, t
Show HN: Generate Claude Code Workflows using Spec Driven Development approach
I have been using a Spec-Driven Development approach for all mid+ size coding tasks since Feb 2026: https://news.ycombinator.com/item?id=48231575. One of the reasons for developing my own plugin (sddw - spec driven development workflow https://github.com/sermakarevich/sddw/) was to adjust it to my specific needs and the typical size of the features I build. Since then, this approach (sddw) has been presented at a few companies, including Google Poland. One
AI agent streaming in action: barge-in, human handover, and session continuity
You're mid-conversation with an AI support agent. You've explained the problem, the agent is halfway through a response, and the connection drops. When you reconnect, the response is gone.You type the same question again. The agent asks the same clarifying questions again. Three minutes of context, gone. Not because the model forgot it, but because the delivery layer stored nothing.Connection drops, page refreshes, and device switches all fail for the same reason: session state lives in the deli

Have LLMs made anyone's life substantially better?
I can't help but come to the conclusion that almost everyone's life has gotten worse as a result of AI.I'm a software engineer working for a huge company. We have access to AI tools, which is cool, and it saves me time in the sense that it is quicker to write code. Yet, despite writing code taking time, I never thought that it was a tedious usage of time. As a developer, the times that I got to actually sit down and start banging out code were some of the most fun times I've
Show HN: Raft in Rust
For quite sometime, I’ve wanted to give implementing the Raft consensus protocol a try. I first looked at MIT’s 6.5840 Distributed Systems labs as a way to do this but it is in Go and my Go skills have atrophied as well as I have been deeply investing time in Rust. The other option was PingCAPs approach (https://github.com/pingcap/talent-plan/blob/master/courses/d...) but I also wanted the ability to define my own types and RPC approach, so I decided to do

SilverTorch: Index as Model — A New Retrieval Paradigm for Recommendation Systems
We’re introducing SilverTorch, a reimagining of recommendation systems that unifies all retrieval components for user generated content under a unified architecture. SilverTorch shows up to 23.7x higher throughput compared to the state-of-the-art approaches. It’s also showing 20.9x more compute cost efficiency compared to a CPU-based solution while also improving accuracy. Our research paper, “SilverTorch: A Unified Model-based System to Democratize Large-Scale Recommendation on GPUs,” accepted
Is WebSockets enough for AI chat?
WebSockets are the right protocol for production AI chat. But that fact doesn’t prevent the failure most teams hit first. An enterprise load balancer closes the idle connection at 60 seconds during a tool execution wait. Your reconnect logic fires in under a second, the agent keeps running server-side, and the client receives nothing from the gap. No tokens, no tool call results, no context.The reconnected socket has no view of what happened while it was down. Three conditions cause this routine
Show HN: Spec-Driven Development Workflow for Claude Code
Spec Driven Development approach allows to squeeze more from coding agents thanks to few strong concepts:
- decomposition across two dimensions. first you generate specs in multiple steps (requirements, code analysis, design), than you split task into multiple subtasks and implement them one by one
- you clear context between every step - after spec generation and after subtask implementation. this helps keep cost low and context clear and focused which boost performance
- specs written to disk
Show HN: Kanban CLI (A local-first, agent-first task manager for the terminal)
Hello HN,Ever since agents have become increasingly common in development, I've been scratching my head as to how to control their randomness. Recently, I decided to emulate an issue-tracking and project-management tool for agent-driven workflows.Kanban is a Rust-based coordination layer designed to provide a feature-rich terminal interface and enforce rigorous workflows. It aims to be versatile and extendable, made to be tailored to any preferred flow. It comes with full git integration an
