Show HN: Mana Pool – Market for Magic Cards
Hi folks. I launched my first startup on HN 15 years ago (see my profile), and I wanted to post here again now.<p>Like my last one, this project comes from one of my life's passions. I have played Magic: The Gathering for 30 years.<p>My co-founders and I think Magic deserves its own market, and this thinking will lead to dozens of ways to make a great app. We consider what we have an MVP, and we are all going to MagicCon this weekend in Las Vegas to walk around in our Mana Pool shirts and talk to people about the future.<p>If HN likes the site, I would appreciate you crashing it before we head out tomorrow night!<p><a href="https://manapool.com/" rel="nofollow noreferrer">https://manapool.com/</a>

Show HN: Booklet – Async forums as an alternative to chat
I built Booklet to solve the problem of too many chat messages at work.<p>Booklet updates classic internet forums and email groups to have a modern UI and high polish. It organizes communications into threads, and summarizes activities into a neat email newsletter - so members can stay updated without having to stay logged in. The async format promotes deeper discussions, while also increasing engagement by making conversations easy to follow.<p>My goal is to make communications more asynchronous - so that I can get back to work, instead of slacking all day. Most early communities have been hobby groups, but my goal is to mature Booklet into a tool that sits alongside Slack in companies.<p>Try it out, and let me know what you think!

My uBlock Origin filters to remove distractions
Repository with my filter lists that block some distractions from sites I want to keep using.<p>I am pretty ruthless removing distractions from my life (e.g. no Instagram, Facebook, TikTok), but some tools I'd like to keep using some parts of it. E.g. Twitter/X, I dislike the feed but I like reading some threads that are shared here or on blog posts. Same for YouTube, I enjoy some videos but I do not want recommendations when I finish the video I was watching.<p>Feel free to suggest more, open issues, pull requests or send me an email :)
Show HN: ElectricSQL, Postgres to SQLite active-active sync for local-first apps
Hi HN, James, Valter, Sam and the team from ElectricSQL here.<p>We're really excited to be sharing ElectricSQL with you today. It's an open source, local-first sync layer that can be used to build reactive, realtime, offline-capable apps directly on Postgres with two way active-active sync to SQLite (including with WASM in the browser).<p>Electric comprises a sync layer (built with Elixir) placed in front of your Postgres database and a type safe client that allows you to bidirectionally sync data from your Postgres to local SQLite databases. This sync is CRDT-based, resilient to conflicting edits from multiple nodes at the same time, and works after being offline for extended periods.<p>Some good links to get started:<p>- website: <a href="https://electric-sql.com" rel="nofollow noreferrer">https://electric-sql.com</a><p>- docs: <a href="https://electric-sql.com/docs" rel="nofollow noreferrer">https://electric-sql.com/docs</a><p>- code: <a href="https://github.com/electric-sql/electric">https://github.com/electric-sql/electric</a><p>- introducing post: <a href="https://electric-sql.com/blog/2023/09/20/introducing-electricsql-v0.6" rel="nofollow noreferrer">https://electric-sql.com/blog/2023/09/20/introducing-electri...</a><p>You can also see some demo applications:<p>- Linear clone: <a href="https://linear-lite.electric-sql.com" rel="nofollow noreferrer">https://linear-lite.electric-sql.com</a><p>- Realtime demo: <a href="https://electric-sql.com/docs/intro/multi-user" rel="nofollow noreferrer">https://electric-sql.com/docs/intro/multi-user</a><p>- Conflict-free offline: <a href="https://electric-sql.com/docs/intro/offline" rel="nofollow noreferrer">https://electric-sql.com/docs/intro/offline</a><p>The Electric team actually includes two of the inventors of CRDTs, Marc Shapiro and Nuno Preguiça, and a number of their collaborators who've pioneered a lot of tech underpinning local-first software. We are privileged to be building on their research and delighted to be surfacing so much work in a product you can now try out.

Show HN: I'm building a tool to practice numbers in Arabic
Recently moved to Egypt, and in dire need to get the numbers down. Great excuse to explore learning software some more.<p>Possibly very niche, but maybe it is useful for someone else out there. Feedback is always welcome.
Show HN: Dittofeed – 1-Click deploy, self-host Mailchimp alternative
Hi HN, we've released Dittofeed v0.4.0, a significant update primarily focused on facilitating self-hosting. Dittofeed is an open source (MIT licensed) alternative to platforms like customer.io, mailchimp, klaviyo, iterable etc.<p>Self-hosting is particularly useful if you:<p>- Want to evaluate Dittofeed without a long-term commitment<p>- Prefer fixed, non-volume based pricing models<p>- Aim to keep all personally identifiable information within your own infrastructure<p>In this version, we introduced 'Dittofeed Lite,' which merges the dashboard, API, and worker services, simplifying deployment, along with providing an easy auth setup.<p>We've also configured a 1-Click Render deployment. The Render setup comes at a fixed cost of $39/month. However, by using alternative hosting solutions for the Postgres and ClickHouse instances (neon, clickhouse cloud), the monthly costs can be reduced to under $20.<p>We personally feel that there’s a big problem with how existing platforms handle pricing, charging insanely high prices with low contact limits, while restricting access to really basic table stakes features.<p>Excited to share this work, and hear your thoughts and feedback!<p>Github Repo - <a href="https://github.com/dittofeed/dittofeed">https://github.com/dittofeed/dittofeed</a><p>Demo - <a href="https://demo.dittofeed.com/dashboard/journeys">https://demo.dittofeed.com/dashboard/journeys</a><p>Docs - <a href="https://docs.dittofeed.com/getting-started">https://docs.dittofeed.com/getting-started</a>

Show HN: Hydra - Open-Source Columnar Postgres
hi hn, hydra ceo here<p>hydra is an open-source extension that adds columnar tables to Postgres for efficient analytical reporting. With Hydra, you can analyze billions of rows instantly without changing code.<p>demo video (5 min): <a href="https://youtu.be/1yzxgb0Oyrw" rel="nofollow noreferrer">https://youtu.be/1yzxgb0Oyrw</a>
github repo: <a href="https://github.com/hydradatabase/hydra">https://github.com/hydradatabase/hydra</a><p>For 1.0 GA release, aggregate queries are over *60% faster* than Hydra beta due to aggregate vectorization. Spatial indexes (gin, gist, spgist, and rum indexes) and pg_hint_plan are now enabled for performance optimization.<p>postgres is great, but aggregates can take minutes to hours to return results on large data sets. long-running analytical queries hog database resources and degrade performance. use hydra to run much faster analytics on postgres without changing code.<p>for testing, try the hydra free tier to create a column postgres instance on the cloud. <a href="https://dashboard.hydra.so/signup">https://dashboard.hydra.so/signup</a>
