#832Building MyLawnGuide (https://mylawnguide.com) as a way to help me organize and plan my yard maintenance for the season.
Enter your zip, type of grass you want, where you're starting and it gives you a rough plan to follow for seeding, feeding, and pre-emergent.

#833Working on https://getAiNative.com
I kept seeing the same thing across engineering teams: everyone bought Copilot or Cursor seats, people used it for a few weeks, and then output didn't really change.
The tooling is good but teams are treating AI like autocomplete instead of integrating it into how they actually ship code.
My take is that AI starts making a real difference when you apply the same discipline you already have for software engineering.
Plan the work, implement, write tests, commit, open a PR, get it reviewed. If you just vibe code with no structure around it, you get messy diffs and hallucinated tests that nobody trusts.
So I'm building around that workflow. Think of it as giving AI the guardrails of your existing eng process.

#834I'm working on TravelTracker, a travel journal that doesn't track you back.
I kept running into the same thing with every travel app I tried: they either wanted background GPS running 24/7, or they quietly turned my trip history into ad-targeting data. I wanted to remember where I'd been without handing that memory to an ad broker. So I built the thing I wanted.
No analytics, no pixels, no third-party tracking. You log trips manually (countries, national parks, UNESCO sites, cities, photos, journal entries), the data lives in one account that syncs across web, iOS, and Android, and the business model is a subscription, not your travel history.
Just shipped iOS today. Android went live last week, and the Web App has been live for a little while now.

#835I'm building a Redis real-time backup platform with PITR (point in time recovery) to the exact millisecond. Besides downloads it has an emergency recovery option where you connect the Redis client directly to the master-replica to receive the latest version.
The key explorer let's you change data on the fly and receive notifications in real time when a condition is met (if value contains X).
It's build in Rust on bare metal wit isolation between clients and data.

#836I'm working on a local proxy application locally. I was building a mcp application in my organization and had to make some code changes to match what we wanted on the AWS load balancer. So I thought why not have an application that runs a server, takes some rules and allows users to add applications.
That way, I can expose the server's address on network and have everything work from there. It is still a WIP but I have couple of plans to make it better.

#837I'm still working on my Calendar API. Currently I'm implementing the events CRUD endpoints. I haven't addressed booking / appointment / free slot finding yet, I intend to investigate how other API's handle this. Especially since I want to support multiple resource types (rooms, machines, people, chairs....). Not sure yet if REST will be appropriate there, or if I'm better off picking something like GraphQL there

#838I've been writing a 'book' (more of an extended blog post that I'd like to put out for free) attempting to explain quantum computing to a layman-ish audience. I sort of got inspired to do this after seeing so many QC PR posts on HN, and finding the educational material in this space to be either too academic, too narrow in scope, or totally facile. I think given the incredible hype (and potential promise) of this ind…

#839It's not software related but could be in future.
My father, a documentary photographer and political dissident during communist regime in Czechoslovakia have a large photo archive that he was never able to publish. I have launched a public fundraiser to support the digitization and publication of the photo archive. There are many valuable photographs that public should see.
More info about project: https://tobiaskucera.art/en/digitalizace-fotoarchivu-meho-ot...
I'd like to create a web catalogue that anyone could search photographs by date, place, names, etc. I'm not sure what backend should I use. Immich has nice features like face detection, search by content, GPS, etc. but it is not suitable for front end.
