Show HN: Mercury – Turn Python Notebooks to Web Apps Hi! We're Piotr and Aleksandra, founders of Mercury (https://bit.ly/3jUfUPz), an open source framework for converting Jupyter Notebooks to Web Apps. You can turn Python notebook into interactive web app, static website, presentation, report or dashboard and share it online with non-technical users. You can self-host Mercury or use our hosting service (coming soon!). Our GitHub: https://bit.ly/3tPKf4g Sharing Python notebooks is challenging. You can't send notebook directly to non-technical stakeholders. You need to copy-paste results/charts into Word/PowerPoint or rewrite notebook to web framework. Mercury converts notebook to web app. User can execute cells but can't edit them. Mercury offers set of widgets that can be added to the notebook. When serving notebook with Mercury, widget change triggers automatic re-execution of cells. Not all cells are re-executed, only cells with widget definition and below, so you can cache results from previous cells execution (loading large dataset or model). Mercury comes with handy feautures to make sharing easy: - decide to hide or show notebook's code, - add authentication to notebooks, so only selected users can view them, - export final notebook to PDF or HTML file, - all to create output files in notebook, and make them downloadable, - share multiple notebooks on one Site. How does Mercury differ from existing solutions? - it was desinged for notebooks, it offers simple re-execution of cells after widget update, - it has built-in authentication. Mercury is available on AGPLv3. We would like to offer a hosting service, to make deployment very easy (just upload notebook to have website). We offer commercial license for companies looking for private forks and dedicated support. We’d love to hear from the HN community about this framework! March 17, 2023 at 11:15AM

Show HN: Musikalia, an iOS Music Player for Kids https://bit.ly/3ldG6Fz

Show HN: Musikalia, an iOS Music Player for Kids Hi HN! Yesterday I finally released Musikalia, an iOS music player I built for my son, so he could be in charge of the music. It is my first SwiftUI project, and I have been (very) slowly building it since December '21. It aims to be fun and easy to use for small children, while not being another addictive app. We are using it almost daily, and in our (n=1) experience, it achieves just that: my 3-year-old loves to listen to music using Musikalia, but at the same time it never feels like he has problems leaving it again. I've also written a bit on the back-story on my blog: https://bit.ly/3Lv0AnY I hope this may be useful for other families! - Harry https://apple.co/3mZXcY5 March 16, 2023 at 11:43AM

Show HN: Quality News – Towards a fairer ranking algorithm for Hacker News https://bit.ly/3JmCLvU

Show HN: Quality News – Towards a fairer ranking algorithm for Hacker News Hello HN! TLDR; - Quality News is a Hacker News client that provides additional data and insights on submissions, notably, the upvoteRate metric. - We propose that this metric could be used to improve the Hacker News ranking score. - In-depth explanation: https://bit.ly/3ERwyq6 The Hacker News ranking score is directly proportional to upvotes, which is a problem because it creates a feedback loop: higher rank leads to more upvotes leads to higher rank, and so on... → ↗ ↘ Higher Rank More Upvotes ↖ ↙ ← As a consequence, success on HN depends almost entirely on getting enough upvotes in the first hour or so to make the front page and get caught in this feedback loop. And getting these early upvotes is largely a matter of timing, luck, and moderator decisions. And so the best stories don't always make the front page, and the stories on the front page are not always the best. Our proposed solution is to use upvoteRate instead of upvotes in the ranking formula. upvoteRate is an estimate of how much more or less likely users are to upvote a story compared to the average story, taking account how much attention the story as received, based on a history of the ranks and times at which it has been shown. You can read about how we calculate this metric in more detail here: https://bit.ly/3ERwyq6 About 1.5 years ago, we published an article with this basic idea of counteracting the rank-upvotes feedback loop by using attention as negative feedback. We received very valuable input from the HN community ( https://bit.ly/3mi2eyL ). Quality News has been created based largely on this feedback. Currently, Quality News shows the upvoteRate metric for live Hacker News data, as well as charts of the rank and upvote history of each story. We have not yet implemented an alternative ranking algorithm, because we don't have access to data on flags and moderator actions, which are a major component of the HN ranking score. We'd love to see the Hacker News team experiment with the new formula, perhaps on an alternative front page. This will allow the community to evaluate whether the new ranking formula is an improvement over the current one. We look forward discussing our approach with you!

Show HN: Chainloop, A Software Supply Chain Attestation solution devs won't hate https://bit.ly/3LwXKP8

Show HN: Chainloop, A Software Supply Chain Attestation solution devs won't hate Hi, my name is Miguel and I am very happy to share what's been months worth of work :) The project has rough edges for sure, but any early feedback, comments or concerns are appreciated! === The Problem === You work on the Security and Operations (SecOps) team in charge of your organization's Software Supply Chain Security. You feel pretty good about the state of things already, your developer teams are signing their commits, deliverables, scanning for vulnerabilities,… Life is good! Then you realize that you are not compliant with the latest security requirements. You get referred to slsa.dev and are told that you need to be at least level 3, whatever that means! Aha! I “just” need to implement an attestation and artifact layer in our Software Supply Chain, which you complete after a couple of months of work. Now to the easy part (or what you think). To make the developer teams adopt it. You quickly realize that standardizing best practices and security requirements is very hard. Development and SecOps team dynamics are clashy and poorly defined due to priorities mismatch. Also, from the developer's point of view, it’s very time-consuming and frustrating to pollute your CI/CD systems with convoluted, error-prone and complex processes to comply with the SecOps team. So there has to be a better way that satisfies both sides... === The Solution === Enter Chainloop. You can think of it as an API for your organization's Software Supply Chain that both parties can use to interact effectively to meet their mismatched priorities. SecOps teams regain security compliance, visibility, standardization and control by having a mechanism to define and propagate attestation requirements. Developers, on the other hand, get jargon-free tooling that can be used to meet compliance with minimum friction and effort. === Give it a try === Eager for feedback from the community so please reach out. Happy to chat! Thanks! PS: You can see an attestation end-to-end demo here https://www.youtube.com/watch?v=Q_0dlBqKtIU&t=384s https://bit.ly/3lbedhq March 16, 2023 at 12:34PM

Show HN: Story Bot – Blog where all the posts are written by AI https://bit.ly/3llKIt9

Show HN: Story Bot – Blog where all the posts are written by AI I created Story Bot, a blog powered by AI. It receives a prompt and generates a story with a title and an image. Almost all the content on the website has been generated exclusively by AI. With the upcoming evolution of AI, I wanted to do a fun project where everyone can participate. I ended up with this platform, I believe that a blog is something that can survive time and can show us how technology has been evolving. It could be a type of “archive”. https://bit.ly/3LsH9Mr March 15, 2023 at 10:02PM

Show HN: Discontent – Extension to combat garbage search engine results https://bit.ly/3JhZYPG

Show HN: Discontent – Extension to combat garbage search engine results Creator here. In a nutshell this extension is a "Like / Dislike" system but for website results. I miss the days of things like the YouTube dislike bar, where you can quickly assess if something is good or not. Currently sitting at ~90 users. To get it off the ground I've scraped the last year of HN to make a set of good links, and used a few content farm blacklists to make a set of bad links. Right now it's semi-useful and should only get better with time. There are some simple measures in place to prevent spam & abuse, but will cross that bridge if it ever comes. All feedback welcome! https://bit.ly/3LgYIyS March 15, 2023 at 02:31PM
