    Project mention: Ask HN: Which "open-source alternatives" have succeeded? | news.ycombinator.com | 2024-07-01

    With how anti-consumer the recent Plex moves have been, Jellyfin [1] has gotten really popular among self-hosting community. It is arguably the best alternative to Plex in terms of features and the amount of freedom given to the user.

    Project mention: Flameshot – Powerful, yet simple to use open-source screenshot software | news.ycombinator.com | 2024-06-11

    I've been using ShareX (https://getsharex.com/) for some years, which is also open-source, and very featureful while not feeling too bloated, though Windows only.

    I'll have to have a look at this next time I'm on a Linux desktop, as I found the options lacking compared to ShareX last time I looked.

    Project mention: Quartz: A Deterministic Time Testing Library for Go | news.ycombinator.com | 2024-07-15

    This may be your personal experience but it is used successfully and happily by many in a variety of domains way different to "boring OOP back-ends". No popular general purpose language is confined to a single domain like you describe. C# lets you do things like writing a competitive Redis implementation[0], advanced physics engine that beats Jolt[1] or a game engine that does not rely on C++ or C[2], cross-platform applications[3] and so on and so forth. The language itself lets you go from high level FP style approach for business domain modeling to very low-level data crunching that is competitive with systems programming languages.

  • WaveFunctionCollapse

    Bitmap & tilemap generation from a single example with the help of ideas from quantum mechanics

    Project mention: Wave Function Collapse | dev.to | 2024-06-02

    WFC is a very popular procedural generation technique that can generate unique outputs of tilemaps or levels based off prompted input images or tiles. WFC is an implementation of the model synthesis algorithm. WFC was created by Maxim Gumin in 2016. The WFC algorithm is VERY similar to the model synthesis algorithm developed in 2007 by Paul Merrell. For more information on WFC specifically, you can review Maxim's Github repo here.

  • sst

    Build modern full-stack applications on AWS

    Project mention: Vercel ends open-source sponsorship program giving projects 24hr notice | news.ycombinator.com | 2024-06-14

    In case it’s helpful to anyone who has to jump off vercel:

    I recently had to transition my company off of vercel for reasons unrelated to this (wanted to use cloud infra primitives that vercel does not provide, and wanted to leverage the large amount of AWS credits my company received) and found that sst.dev [0] to be easy to migrate to and a joy to use in general. It leverages open-next to deploy next.js projects on AWS in a serverless way.

    I’ve been enjoying using it so much that for my next project I think I’ll skip vercel altogether and use sst from the start.

  • CleanArchitecture

    Clean Architecture Solution Template: A starting point for Clean Architecture with ASP.NET Core (by ardalis)

    Project mention: AdonisJS | news.ycombinator.com | 2024-06-20

    Looking at this, it has similar aspects as ASP.NET Core, and the same flaws as the Controller per class design used. Methods such as "create", "show" and "store" do not share a state, they shouldn't share a class either.

    However, you can rectify this, by just not trying to share a class with any of those. In .NET Steve Smith, aka Ardalis shows how to do this with his Clean architecture idea [1], Idea is to make a class for each endpoint. This also makes it easier for "Update" classes to share functionality with other "Update" classes and so on.

    Project mention: The Rise and Fall of the LAN Party | news.ycombinator.com | 2024-04-24

    Recently, my friends and I recreated our old LAN parties. Went up to a cabin in the woods, brought some cheap network switches, and had everyone install OpenRA (https://www.openra.net/, open red alert), and had a blast, even with everyone on laptops (mac/win). You can still do this in 2024 and it's worth it!
