I lived in Germany for four years, but no longer there. I got 42% German / 20% Autistic grade and I am not European at all.

Never bought a Samsung phone, TV or Fridge. Smart is now translating into "Ad-injection" in various appliances and I hope this backfires!

Hi, HN community,I have built a CLI tool called Recaller to fuzzy-search your command history based on recency and frequency. Recaller can magically curate your history and hands over most useful commands to you. Think it like a second brain while recalling history.Please check it out and let me know your feedback.

I am working on Scharf, an open-source SAST tool to identify and auto-fix 3P GitHub actions those are prone to supply-chain attacks. It is blazing fast and written in Go.

This tool can cutdown hours of grind for Security engineers.

Welcome to "Scharf", a blazing-fast security scanner for hardening third-party GitHub actions with mutable references. Using mutable references (version tags, main/master/dev etc.) is a security vulnerability that can result in supply-chain attacks.The recent `tj-actions/changed-files` security incident is scary, so we built a mutable-reference scanner that performs a deep scan across branches...

I am building "Scharf", a blazing-fast security scanner for reporting and hardening third-party GitHub actions.

For whoever aware of recent `tj-actions/changed-files` security incident, I built a mutable-reference scanner that performs a deep scan across branches to identify all third-party GitHub actions used in organization Git projects. The output report can be exported to CSV or JSON (default).

Using mutable references (version tags, main/master/dev etc.) is a security vulnerability that can result in supply-chain attacks.

Re:Whispr: Securely develop software without leaking secrets on Sunday October 20, 2024 @10:44PM (#41900243)
Whispr is created to enable secure software development by simplifying developer experience.

It is easy for developers to place their database credentials in a `.env` file for local testing and accidentally commit them to a version control system.

Even not committed, storing credentials as plain text is a risk as per MITRE ATT&CK Framework: credential access.

Whispr helps you store nothing locally and provides on-demand, Just In Time (JIT) secret access for applications. It supports AWS, Azure and GCP secret vaults.

Best part is no bash scripts nor CLI commands required. The tool is language & application agnostic.

Re:A web version of Anthropic's prompt engineering interactive tutorial on Saturday May 18, 2024 @09:37PM (#40403470)
It is not just for storing variations of a prompt. It separates context to make intentions clear. Here is a XMl prompt serialized from PromptML program:

https://gist.github.com/narenaryan/651d8081eaaffa846e05da7a3...

You can test it with Claude and GPT-3.5 or GPT-4o, and they all will bring strikingly bring similar results with differences in detail.

YAML & XML serializations are coming in v0.6.0 of PromptML.

Re:A web version of Anthropic's prompt engineering interactive tutorial on Saturday May 18, 2024 @08:41PM (#40403243)
Hi there. Your question is valid. That's why we built Prompt Markup Language:

https://github.com/narenaryan/promptml/ https://www.promptml.org/

It isn't XML nor JSON, but a DSL built especially for writing prompts. We do not have published benchmarks but running few examples, we see consistent outputs from LLM, and supplements RAG by separating context and using it for enriching prompt.

Re:We are building a smart bookmark manager for Chrome. Need your feed... on Sunday December 10, 2023 @09:39PM (#38597077)
That's a great question. Right now, we don't have that feature incorporated, but we do thought about hydrating existing bookmarks and making it part of memory graph. Chrome's bookmark API is so primitive, and we have seen many issues keeping things in sync (being cautious here..).

I took your point down. Thanks for brining it forward.

Hi hackers. We (at Vidura Labs) are working on an amazing alternative to standard browser bookmarks that can smartly organize, and visualizes bookmarks, so that your brain can easily follow, rather than searching through a heap of objects(like in traditional bookmarks).It is a chromium extension that lets you bookmark any web site, automatically tags it and puts it into the right folder (or...

Hi HN community: I am one of the creators of vidura, the missing "AI prompt manager" for prompt engineers. Vidura is essentially a Prompt Management System(PMS) where a user can categorize, tag, and test their GPT and Stable diffusion prompts in one single place. With syntax highlighting and export responses to PDF, it provides a practical user experience.
