Show HN: cmaps.io – Transform Thoughts into Visual Masterpieces Hey! Just launched my new project! It's a tool to rethink the way we study and take notes. Human thinking is inherently associative, not linear. Check it out at https://cmaps.io I would love to get some feedback! Thanks! https://www.cmaps.io/ November 20, 2023 at 02:25AM

Show HN: "Awesome" Engineering Games (List) https://ift.tt/TRbEjFh

Show HN: "Awesome" Engineering Games (List) I've spent way too much time both playing and finding engineering-focused games, and haven't been able to find very detailed or comprehensive lists online. So I made one :) These games are both fun and often quite educational, presenting gamified versions of real-world challenges and professions. There's a lot of different sub-genres of "engineering game", such as: * Factory automation (Factorio, Dyson Sphere Program) * City builders (Cities: Skylines, Anno series) * Route-builders (Mini Motorways, Railway Empire) * Comp sci (TIS-100, Bitburner) All games on the list are very highly reviewed. I've played most (but not all) of them, and provided personal recommendations alongside the reviews. Many of them are also playable on GeForce Now (if you don't have a gaming PC). Please contribute if you know of more, or have any comments/suggestions! https://ift.tt/R8vCLHB November 20, 2023 at 12:52AM

Show HN: YouTube banned adblockers so I built an extension to skip their ads Hi HN! Since Youtube no longer allows AdBlockers, I built my own extension to get around their video ads. If there is an ad it temporarily manipulates the video; Mutes the volume, sets speed to 10x, and skips it if there is a button.

Show HN: Bemi – data versioning and time travel for PostgreSQL https://ift.tt/dDeOk1r

Show HN: Bemi – data versioning and time travel for PostgreSQL Hi HN, we’re Evgeny, Arjun, and Donna - the builders of Bemi ( https://bemi.io ). Bemi is an enhancement of your existing transactional database to unlock time travel querying. We enable engineers to track all PostgreSQL state changes. We used to all work together at a startup five years ago, and now have got the gang back together to work on Bemi! Many open-source libraries already track data changes, but they’re not reliable since they don’t track changes made outside ORMs with direct SQL queries. Additionally, they come with runtime performance overhead since they’re making database inserts in callbacks. We’ve also consistently seen hacks that engineers write on top of the libraries to store additional context or make it easier for them to query. There are databases already available for event sourcing, but we take a fundamentally different approach. We don’t want engineers to have to rearchitect their existing code, switch to highly specialized databases, or use unnecessary git-like abstractions. We want your system to work the way it already does with your existing database to allow keeping things as simple as possible. Bemi uses change data capture (CDC) by connecting to a built-in replication log of a database, ingesting all changes on the database level, and storing them in a structured format in a destination database. The database connection details can be securely configured through our dashboard UI in a few seconds. People also try adding database triggers to track low-level data change. The main difference is that Bemi integrates not just on the database level, but also on the application level with packages in the most popular frameworks (being released soon) and a Bemi worker automatically stitches application metadata with the lower-level change data to get the “where” (API endpoint, worker, and so on) and “who” (user, cron job, and so on) behind a change. This allows being able to revert all data changes made within an API request, for example. For the sake of transparency, we intend to make money by implementing usage-based pricing and a multi-cloud hosted option. Bemi’s free for early adopters. We are still early though and would love your feedback. What do you think HN? https://bemi.io/ November 17, 2023 at 09:42PM
