I recently quit my salary job after 16 years and am consulting in nuclear engineering now. I have a few passion projects that I'm working on (between the somewhat substantial consulting work that came out of the woodwork):

- Nuclear Reactor Starter Kit --- an open source set of procedures, processes, templates, and maybe even some IT advice that should help newcomers start companies with nuclear quality assurance programs easily and quickly while also making a new format in which nuclear companies can share lessons learned in efficiency.

- Reactor Database --- similar to the iaeas PRIS but focused on reactor development rather than power reactors. Will include nuclear startup company tracking with details gleaned from statements and maybe extrapolated where necessary from simple simulations. Will include things like fuel cost and licensing progress. This way people can more easily separate vaporware from real nuclear, and keep track of promises vs delivery.

Papers with code for quantitative finance. Still just thinking about it. Replicating research is a great way to learn a field.

>90% of the work to replicate academic research in quant finance is data collection and cleaning. Academics have WRDS, Bloomberg, and research assistants. Others need to find cheap vendors of acceptable quality. Write scripts to fetch and clean. Actual algorithms and analysis (the fun part) are a tiny fraction of the total effort.

Project objective is "good enough" data collection & cleaning for daily frequency equities, futures, and FX. In that order. Annual data budget target < USD 500. Cheaper is better.

The plan: You are a PM and Engineer - and so is the AI. You both write tickets and you both complete them to iterate on your code.

https://codeplusequalsai.com

You can build webapps very quickly, especially AI-enabled ones, and deploy them on a subdomain. Other users can sign up and use your webapp, and any tokens they use will be billed to them and you will get a large cut (80%) of the margin earned on the tokens billed - as I bill 2x OpenAI API token costs to create this margin.

So ideally you can validate your idea by rapidly building a prototype and evening earning revenue to boot.

I built https://startthelanding.com mostly for myself as I have needed it a lot over the past few years and always ended up building quick one offs. I'm now working on marketing it through a few different channels while at the same time starting work on my main project that I needed the landing pages for which is a fashion for tech/finance people site. I'm going to be doing a big social campaign for that one soon involving myself so I'm pretty excited but also quite scared since I'm not really the post myself on socials type.

Because I love building APIs and backend services, I built a simple IP geolocation service with the best developer experience. It has free (rate-limited) access and affordable paid tiers. Check it out: https://ip-sonar.com

This is cool - how does IP geolocation work? How do you know that xyz IP is at this particular spot?

Edit: I see you are using MaxMind database - do you add some sort of additional analytics or overlay on top of that?
