Show HN: Open-access book on platform governance https://ift.tt/XtMpLfd

Show HN: Open-access book on platform governance Hi there, I'm a political theorist, a professor at Northwestern law school and a founding fellow, board member, etc. of the Integrity Institute. I also was the in-house democratic theorist on Facebook's "civic integrity" (election protection) team for a while, and helped out with the research supporting the creation of the Meta Oversight Board. I just published an academic book with Cambridge University Press bringing together those experiences with research in political science to argue that the way forward for mitigating the harms of big internet platforms and governing user behavior on them is to create global direct democratic institutions for them. You can read the whole book for free on Cambridge's website or by downloading the open-access (license CC-BY-NC-ND 4.0) PDF at the link. If you want a hard copy, you can also buy it in paperback or hardcover. https://ift.tt/HyBkCQJ August 5, 2023 at 12:21AM

Show HN: Open-source library to manage todo items in Python code I made this library that collects all TODO items from a python project, creates automated summaries and notifies them over email, SNS or SES etc. It is highly customizable allowing to add custom summaries, custom notifier and integration with downstream applications. https://ift.tt/b21kXfu August 4, 2023 at 11:04PM

Show HN: Open-Source Favicon Provider https://ift.tt/JQLujz8

Show HN: Open-Source Favicon Provider Hey HN, We couldn’t find a reliable favicon provider for our CRM [1]. There are existing solutions (FaviconKit, Google faviconV2, ...) but we have faced issues with all of them: rate-limiting, down-time, inconsistent icon size. We were looking for a solution that is: 1) reliable : no down-time ; 2) accurate : request a specific icon size to optimize for user bandwidth ; 3) high-quality : that provides the highest resolution icon available for a given requested size ; 4) open-source : this is a common need and a simple problem to solve: an open solution should exist and anybody should be able to contribute or to host it. Technical details: Here is the source code: https://ift.tt/4R20WXQ . The way it works is very simple. We have implemented a few strategies to fetch favicons: get favicon from html meta/link tags, call Google Favicon API. Then we retrieve the image and store it into S3. The next time someone asks for the image it is usually served from our CDN cache directly. If not, then it’s pulled from S3. Cloud Hosting: We are hosting a server on favicon.twenty.com. We will be using it to power Twenty CRM, so it will be maintained up and running for our own needs. Feel free to use it by directly by embedding images like this: https://ift.tt/gwSvQLY or https://ift.tt/wMTqXI0 [1] https://ift.tt/SaHWziQ https://ift.tt/4R20WXQ August 4, 2023 at 01:24AM

Show HN: Zep – pgvector-based memory store for LLM apps https://ift.tt/gXJoWT4

Show HN: Zep – pgvector-based memory store for LLM apps Hey HN - we launched Zep's document vector DB today. Zep is an open source memory store for LLM apps, and this builds on existing chat history memory persistence, embedding, and enrichment capabilities. Zep uses Postgres and pgvector for database operations and vector search. Vector search can be complicated on Postgres, with careful configuration required at both index creation and query time. We've focused on significantly improving this developer experience. Zep automatically selects index and query parameters for developers based on best practices and known heuristics. Vector database operations are exposed via a simple Python (and LangChain) API for working with document collections, documents, and search results. While we focus on LLM App use cases, you can turn any Postgres instance with pgvector into a vector database with great DX. Our launch announcement: https://ift.tt/P8mWFyY... -Daniel https://ift.tt/eCGZh5X August 3, 2023 at 11:47PM
