Show HN: Trading simulator with hidden dates to prove investment skill
Juncture Lab is a trading simulation platform designed to help finance professionals build verifiable track records by trading in hidden historical market conditions. The tool addresses a gap in the finance industry where credibility is traditionally established through resumes rather than demonstrated skill, and targets university finance programs as an alternative to Bloomberg Terminal access. ---
Be intentional about how AI changes your codebase
As AI coding tools become commonplace, developers must adopt a deliberate, thoughtful approach to their integration rather than accepting AI-generated code uncritically. Without intentional oversight, machine-generated solutions risk introducing technical debt and maintenance challenges. The most effective strategy treats AI as an augmentation tool that requires the same rigorous evaluation as human-written code, ultimately strengthening both code quality and team capability.
Show HN: App Feedback Hub – A macOS App for Managing App Store Reviews
A new macOS app lets App Store developers view, filter, and reply to customer reviews across all their applications from a single interface, without needing to access App Store Connect. The tool features search functionality, automatic translation, and local-only credential storage for privacy. The developer created it to address the growing pain of managing reviews across multiple apps.
Show HN: Untitled88 – Query your QuickBooks data in plain English
Untitled88 has launched a QuickBooks integration that enables users to query their financial data using plain English rather than traditional database queries or software navigation. The tool simplifies financial data access for business owners and accountants without technical backgrounds, making it easier to extract insights from QuickBooks records on demand.
EsoLang-Bench: Evaluating Genuine Reasoning in LLMs via Esoteric Languages
EsoLang-Bench is a new evaluation framework that tests whether large language models truly understand programming concepts by having them solve tasks in obscure, rarely-used esoteric programming languages. By moving beyond common training data, the benchmark aims to distinguish genuine reasoning from simple pattern matching in AI systems.
Show HN: We Built Kaggle for AI Agents
Hive is a new crowdsourced platform that enables AI agents to collaborate and compete on benchmark tasks by sharing insights and iteratively improving solutions together. The platform supports multiple established benchmarks and OpenAI's Parameter Golf Challenge, while allowing users to submit custom tasks and integrate their own AI models.
Show HN: Just Built an AI Notetaker (Web, iOS and Android)
A developer has launched MindNote, an AI-powered note-taking app available on web, iOS, and Android that intelligently captures and organizes information from voice, video, meetings, and screenshots. The platform already has paying users and the creator is seeking growth strategies and engineering talent to scale the business and develop enterprise-focused features.
Show HN: SomaOS – rebuilding the desktop so AI is native to it, not bolted on
SomaOS is an operating system purpose-built from the ground up to treat AI agents and humans as equal desktop users rather than master-and-tool relationships. The system features dual-interface native applications, a Human-in-the-Loop approval system for conflict resolution, and a comprehensive suite of AI capabilities integrated directly into the OS architecture. Built on custom Linux with a GPU compositor, it enables agents to interact programmatically with the same applications and data that humans navigate visually. ---
Show HN: Blik360 – open-source 360 feedback (self-host alternative to Lattice)
Blik360 is a new open-source platform providing self-hosted 360-degree feedback capabilities as a cost-effective alternative to commercial services like Lattice. The tool allows organizations to manage performance reviews from multiple perspectives while maintaining complete control over their data. It appeals to companies seeking customization options and independence from subscription-based HR software.
Cockpit is a web-based graphical interface for servers
Cockpit is a lightweight, web-based server management interface that runs as a real Linux session in the browser, supporting major distributions like Debian, Fedora, and RHEL. It enables sysadmins to handle common administrative tasks and manage multiple remote machines via SSH, while allowing seamless integration with traditional terminal-based workflows. The open-source project welcomes community contributions through its documentation, Matrix channel, and mailing list. ---
Show HN: Claude Skill to create DDB-backed endpoints in AWS
Sometimes I just need a place to put stuff that's not local. Apps exist that it make it easy to create an endpoint but I figured it was easier and cheaper to just make a skill. From the description: Create a token-secured REST API endpoint backed by AWS Lambda and DynamoDB with full CRUD and paginated list support. Deploys via CloudFormation. Use when user wants to quickly spin up an API endpoint, create a simple REST API on AWS, build a quick data store with an API, set up a Lambda+DynamoDB endpoint, or needs a fast way to log and retrieve structured data. Triggers on "create an endpoint", "quick API", "Lambda endpoint", "DynamoDB API", "CRUD endpoint", "log data to AWS". Example use: Thariq's recent post on how the team uses Claude Skills has a section on logging skill use with a PreToolUse hook (https://x.com/trq212/status/2033949937936085378). His example code shows logging to a local file but for company-wide tracking, you'd want to log to a central place. I used my skill to stand up an endpoint for this and my ~/.claude/hooks/log-skill.sh POSTS to it: skill=$(echo "$prompt" | awk '{print $1}' | sed 's|^/||') args=$(echo "$prompt" | sed 's|^/[^ ]||' | sed 's|^ ||') # Build the JSON body body=$(jq -nc \ --arg skill_name "$skill" \ --arg invoked_by "$USER" \ --arg args "$args" \ --arg session_id "$session_id" \ '{skill_name: $skill_name, invoked_by: $invoked_by, args: $args, session_id: $session_id}') # POST to the endpoint (fire-and-forget so we don't block the prompt) curl -sf -X POST "$ENDPOINT" \ -H "Content-Type: application/json" \ -H "x-api-token: ${SKILL_LOG_TOKEN}" \ -d "$body" \ >/dev/null 2>&1 & Comments URL: https://news.ycombinator.com/item?id=47445554 Points: 1 # Comments: 0
Show HN: Yap, capture your day-to-day with video logs
Hi HN! Yap is a desktop app for your video logs. Open the app, press record and speak your mind. Once you’re done, Yap catalogues your video and makes it easy to find. Download at https://github.com/felipap/yap I built Yap as an alternative to journaling. I love journaling but it takes too long to write everything I want to say. A couple years ago, I started recording myself talking to the camera. I was using Photo Booth, then QuickTime, but the experience wasn’t great. I wanted an app purpose-built for video logs; so I built Yap. Sharing with AI. Yap transcribes and summarizes your vlogs for you (OpenAI key needed). You can then take the transcripts and share them with friends or AIs. I use this to give AIs context about the projects I’m working on, or problems I’m dealing with. Hope Yap can be useful to you too! Comments URL: https://news.ycombinator.com/item?id=47445446 Points: 3 # Comments: 0
