I've been working on a web app that tracks ammo prices from various US ecomm merchants with the shipping costs included. It also tracks price trends and historical prices. Added some tools for enthusiasts to calculate trajectories, recoil, and compare calibers. Using rails, it's been fun and is generally a joy to work on, have learned a lot. https://ammosight.com

#352A new way to type on gamepads designed around the hardware rather than trying to fit gamepad input to a qwerty keyboard.
I’ve been working on it for a few months and I’m hoping to have a demo up at 7:00 PST today for HN to play with :)

#353I’m making a presentation ai assistant. Existing ones don’t cut it… they’re really nice to demo but not good enough for professional use. Full MVP by next week. https://unblank.ai

#354Working on a database compatibility tool. So your app works on SQL Server 2022 on-prem, but does it work on Azure SQL DB, AWS RDS, GCP CloudSQL, etc?
These cloud flavours have a compatible SQL dialect, but it's often details like missing features (CDC and Auditing on RDS are good examples) or differences in system objects that make it difficult to support your app on these platforms.
I capture all sql statements, run them through multiple SQL parsers to find all the system objects your app is using (tables, functions, stored procedures, etc). I then check them all against a catalog I have built of all system objects for every version of SQL Server on every platform.
I then give a report to see which platforms your app will work on, which ones it wont work on and which system objects are the problem.
Other database engines will be added once I get it working end to end (almost there).

#355I made a game called "So you think you know Brisbane?", in which you guess the suburbs of Brisbane, Australia.

I'm working on expanding it to all large cities in Queensland, moving it to its own domain, and monetizing it to cover hosting costs.

#356Working on: Pantry Recipes – AI meal generation based on what’s in your kitchen Over the past few weekends, I’ve been building Pantry Recipes – a mobile app that lets you quickly generate recipe ideas based on the ingredients you already have at home. The idea is simple: - Save or quickly select ingredients you have on hand - Tap Generate Recipes and get ideas instantly - You can also describe what you want to make f…
Cool idea! I’m a big fan of AnyList so this was intriguing.
I think it could be useful to have a “recently generated” section in the Recipes tab that lets you find things you might have forgotten to save. Substitutions could also be a useful feature. For example, if I can’t find Mexican oregano, what else can I use?

#358I am working on a super mario land re-implementation for game boy using C. It's made with the GBDK toolkit so the ROM can be run on a gameboy.
Currently the scrolling and background collision has been implemented, I am working on drawing the enemies... their is still a long way to go.
As for why I am doing this is nostalgia and fulfilled a childhood dream

#360I am working on a curated database of proxy IP addresses frequently used by bots: https://deviceandbrowserinfo.com/product/proxies-ips So far I have ~ 3M distinct IP addresses per 30 days, with a lot of fresh proxy IPs, 1.7M. The DB contains only verified IP addresses through which I've been able to route traffic. It DOESN'T rely on 3rd party/open-source data sources. I also made an open-source proxy IP block list ba…
Wouldn’t this end up flagging a lot of residential IPs due to residential proxies?
