Show HN: Related Website Finder Experiment Thingy https://ift.tt/OxkXipB

Show HN: Related Website Finder Experiment Thingy Been messing with cosine similarity and decided to try calculating nearest neighbors over the entire link graph for the marginalia search engine. Turns out that you can just bruteforce that in a day or two. And the results are pretty good. One drawback is that depending on if you're looking at an older website, a lot of the links are dead. The deduplication isn't great either. https://ift.tt/Wpy4QEl October 9, 2022 at 10:52PM

Show HN: Simplepdf.eu – a browser-based PDF annotator / editor https://ift.tt/duSCHxj

Show HN: Simplepdf.eu – a browser-based PDF annotator / editor Hi HN! I've been working on SimplePDF to solve a problem I encounter weekly: filling out non-editable PDFs [1] --- # About SimplePDF - The documents you load, edit, fill never see the light of my server, everything is processed locally – no remote uploading anything. This includes the PDF generation. - There are no analytics / third party tracking your every move (I do collect usage data, but it's fully anonymous and processed and stored on my server): therefore no annoying cookie banner. You can read more on the Privacy Policy [2] - If someone before you has filled the same document, upon opening it you'll see fields already set, ready to be filled-in, think crowd-sourced fields positioning – saving you time and effort. --- # How does the crowd-sourced positioning of fields work? When a document is loaded in your browser, a fingerprint of the document binary is made, and sent to the server. The document table consists of: document_id, fingerprint and created_at. As soon as you start editing a document, a template is created, containing metadata about the fields (x, y, width, height, type of field, background color...) that is then tied to this document you created. Once you save, this template gets sent to the server. The template table consists of: template_id, document_id, fields (the metadata) as well as created_by_customer_id if you're a customer. As a result, someone else on the other side of the world opening the same document will see the fields you positioned already there – you just saved them the 5min it took you to position them. --- # What's the tech stack of SimplePDF? - NextJS on the frontend - Koa with GraphQL on the backend - Postgres (Managed Database on Digital Ocean) - A 10€ droplet on Digital Ocean --- If you have any questions, comments or feedback (good or bad), I'm all ears! --- [1] The assignments my estonian teacher gives me are usually scanned documents that do not have any editable fields in them.

Show HN: BlockTalk – Banter about what your friends are doing on Web3 https://ift.tt/WFXztVk

Show HN: BlockTalk – Banter about what your friends are doing on Web3 Hey HN, I’m Kamil and one of the two people working on BlockTalk. BlockTalk is going into public beta today! (We're also on Product Hunt, come check us out!) We previously posted about this project under the name “WalletWatch” in a Show HN about 3 weeks ago, and have since integrated your feedback to make it better [1] [problem] As we were trying to see how our friends were using crypto, we noticed that other products were either too complex or only let us passively view what our friends were doing. [solution] BlockTalk is a social network centered around Ethereum transactions. You can easily see, understand, like, and comment on the Ethereum transactions of anyone on the platform. We don’t ask for your email or password, and instead authenticate by asking users to sign a transaction with their Ethereum wallet; we ask for usernames to give a more familiar and user-friendly experience for people that haven’t purchased ENS or other crypto domain names. At the moment, we’re storing user data in Firestore instead of on-chain because the current decentralized channels are too expensive or slow. This also has the added benefit of making the app completely free to use. [what’s changed] Since our last post, we improved the UI/UX, made transactions more understandable, made the app compatible with all viewports, and now don’t require you to create an account to get a feel for the app. [ask] We’d love any feedback you all have! My e-mail is kamil@fwd.exchange if you want to contact us about anything related to the project :) P.S. here's a very old demo of a prototype from a while back [2] [1] https://ift.tt/hoxTuPs [2] https://youtu.be/xhajqKq4G9Y https://ift.tt/eZLoB6W October 9, 2022 at 08:50PM

Show HN: Building a Git teaching tool that runs Git in the browser https://ift.tt/cmSMwyi

Show HN: Building a Git teaching tool that runs Git in the browser Repo: https://ift.tt/F6Uy4HY Harmony was born as a tool to create and/or modify local files, on the fly, in your browser. Few weeks ago I decided to try to implement a sort of version control system in it. I think it would be cool one day to either use it for personal use or to teach Git concepts in a sandboxed area. Harmony is powered by web assembly and it runs all the git related stuff in-memory. In this release I brought an initial support for directories and the possibility to checkout to a particular commit https://ift.tt/j6BpQSm October 9, 2022 at 07:10PM
