    Please meet Loadjitsu, my weekend project, years in the making. Over the years while building different apps and sites, I always felt that I need a modern load testing software.Tools like JMeter, ab are not very easy to use and it seems innovation in load testing which is a crucial part of any software release cycle has been ignored. This is my third attempt at making Loadjitsu, I am so glad that I can finaly release this. A bit more about the software 1. Powered by golang you can run load tests for tens of thousands of connections per second on very average hardware. 2. Cross platform, run…

    We built On-Call Health because our industry has gotten very good at keeping systems healthy, but does little for the engineers on call managing them. On-call can be rough: 97% of engineers experience stress during incidents, 87% after, and 56% experience sleep disruption even without getting paged. We integrate with devtools like Rootly, PagerDuty, Linear, Jira, and Slack (for self-reported data). The tool doesn't provide a diagnosis, but it surfaces signals that a team or individual might be struggling. It's free to use and open-source (we also have a hosted version with mock data if you…

    Hey HN. We’re Jay and Vadim from Highlight.io (https://highlight.io). We’re building an open source [1] monitoring platform for web applications. Today we’re excited to be sharing a performance tool we’ve been working on, which helps you inspect the latency of code execution from the client to the server. As engineers at past startups, we often had to debug slow queries, poor load times, inconsistent errors, etc... While tools like Jaegar [2] helped us inspect server-side performance, we had no way to tie user events to the traces we were inspecting. In other words, although we had…

    When building workflows that rely on LLMs, we commonly use structured output for programmatic use cases like converting an invoice into rows or meeting transcripts into tickets or even complex PDFs into database entries. The model may return the schema you want, but with hallucinated values like `invoice_date` being off by 2 months or the transcript array ordered wrongly. The JSON is valid, but the values are not. Structured output today is a big part of using LLMs, especially when building deterministic workflows. Current structured output benchmarks (e.g., JSONSchemaBench) only validate…

    Balter, A Load TestER, is a new distributed load testing framework I've been working on for the past few months. It is Open Source, and designed from the ground up to support composability. This allows flexibility in the kinds of load tests you are able to run, such as fully stressing the system and then automatically turning off services; or the ability to run a background noise test, and then slam the service with traffic. Let me know what you think!
