Me and my wife (then my girlfriend) have written "realistic" space sci-fi in Finnish for over 20 years. Now with AI we are finally able to translate our stories to English. The quality starts to be there.

There are a lot of small languages in the world, and translation used to be extremely expensive. And there is never too much good space sci-fi.

(We don't write space battles or wars. Our style is slower and bit more philosophical. Light speed is the limit, and travel takes centuries.)

As we move away from reading code more and more, I started learning about OpenSpec as a way to be more spec oriented to develop software. Reading specs in a code editor didnt make sense so I wrote my “OpenSpec IDE”. Very simple desktop app, no subs or accounts. Its really a markdown reader but built specifically for OpenSpec so you can read things in order and summon Claude (others coming soon) to execute the required OpenSpec commands

I have been building document intelligence in enterprise for a long time now, and even with sota OCR, SLMs, LLMs, all the myriad of services now offering this - most of them miss something.

So over the years me (and my team) have built up a lot of experience dealing with these for sensitive industries like healthcare/insurace/lending etc.

We are bringing these ideas out as a router to other parsers, but with some key takes that allow you to manage failures. "Failure is inevitable so route for it."

It is called Openreading - https://openreading.ai/ and open core here: https://github.com/openreading-ai/openreading-core

It is still WIP and will be more polished in a month after some more rigorous testing and benchmarks.

If this is a problem you deal with, would love to chat.

Note: the intent is to launch a managed version that provides more durable compute/retries, parallel execution, intent understanding etc but this is for later.

I'm building a RSS <> Discord syndication tool called [FeedSync](https://feedsync.net).

It's pretty simple to set up and is designed to "just work", set and forget.

Recently, I've been experimenting with an Elixir Lua runtime (https://deflua.com/) to build custom feeds by parsing HTML, which has worked exceedingly well, so hoping to release that soon.

It's an extremely niche product, but has been growing well organically, which is nice for a side project!

A programming language which lets you code multiplayer games like singleplayer games. Every program written in Easel is guaranteed deterministic and snapshottable, which is how it can automatically make your game multiplayer automatically using rollback netcode.

My hope is that teenagers who makes games in Scratch might like to make games in Easel because it means they can make games they can play with their friends, without having to deploy a server or learn anything about networking on synchronization. People can literally make a multiplayer game on their first day of coding.

Currently been working on adding tilemaps.

What I don't understand about your idea is that netcode as far as I understand is way more complex than you make it seem. The netcode for something like a MOBA or MMORPG is drastically different than the netcode for a much simpler turn-based game. They have elaborate synchronization mechanisms to make the illusion not break-down in various ways due to latency.

And then even for simple turn-based games, there has to be elaborate fully-decided like state diagrams for all the various types of disconnect and latency states so that gameplay doesn't desynch or hitch in awkward ways.

I'm working on a way to make some pretty advanced software in a single HTML file.

The idea is simple: store state you'd normally store in a separate database in the document itself.

Then, also give the the document a bunch of powerful APIs granted to it by its host:

(1) Sync changes to the document with live collaborators

(2) Extract data from the document using a simple JSON map config

(3) Boot up a full content CMS from the same simple JSON map config

(4) More features added every month

I'm really excited with even the tiny bit of early traction I've gotten. About a dozen paying users so far.

Long term, I'd love to have this file type (vanilla HTML file + some extra features granted by the host) become a file type other companies offer tools and their own hosting for (like Wordpress).

I'm vibe coding a toy chatbot with OpenCode and GLM 5.3 - I'll open source it once it's meaningfully done (keeping the repo private for now until I am _so so_ sure there are no secrets in it!). This has been an exercise in learning about lots of new AI SWE concepts including some tech (Mastra, LangSmith, DeepInfra) - as well as a chance to try some open weights models. The actual useful output is an iteration loop orchestrator based on GitHub issues/PRs which I have found a lot of fun to use. That'll also be open-sourced.

Initially started as WhatsApp Team Inbox. But, now I am adding telegram bot, emails and MCP support. Eventually, I am going to add like Messenger, Instagram, Line, Viber, Discord, Slack, etc...

So, it will be a bridge between your/your business communication and AI via MCP. If you want to create your own agent you would be able to create as well.

I vibe coded mostly, but once a while I go in and refactor heavy.

I've been working on anti age verification/surveillance projects lately. I put together this thing I call The Mandating Honeypots Project and it shows how anyone with an internet connection and copy + paste skills can trick Linux D-Buses with a simple Python script, proving that if companies want to verify your age by asking the D-Bus interface, it's easy to just tell it to always send 18+, making the whole thing useless. The only reason you'd want ID verification is so you can create the world's biggest and sweetest honeypot.

(https://github.com/Tori-Tech/Mandating-Honeypots-Project)

In that project, I also proposed a tool with heavily redundant password protection that parents could use to keep kids from tampering with the service so the government can stop saying that this is for the kids. I'm planning on doing a mobile device version and/or an ID database focused version, but that's still in the planning phase.

I also want to do a Windows version when they release their 'GetUserAgeRangeAsync' API, but idk if I'll be able to. Windows is always a pain to work with.

It'd be nice if someone had advice or ideas to share, too.
