What are the most interesting or promising technological projects in ecology and sustainable development right now?

In the past, I built an automated cashback and promo code aggregator https://touslescashbacks.com/ that generated a few hundred euros monthly through SEO. I'm now exploring AI-driven side income opportunities and would love to hear about others' experiences and projects in this area.

I've built an app in a highly competitive market, and everytime my app rise to +4 stars, we get around 5 to 7 1 star reviews the same day - It's always a variant of the 2 same messages: "Beware, this app is a scam" - "the developer hacks your data"

I always "report as spam" on the Play store, but Google has never removed any of the reviews. I'm kinda desperate, it takes a lot of time to get genuine reviews, and only one attack of the kind to crash below the 3.5 mark

And ofc, as the review system is different on Apple, my rating on the App store is 4.5, which I'm really happy about

Any tricks against 1 star reviews attack ? Is there anything to do or should I just accept it ?

Hello,

First off, I am by no means an infrastructure or devops guys, I'm a senior nodejs freelance, so some of this is new to me

This is the current infrastructur:e

- A nginx reverse proxy in front of the nodejs API VPS

- A 24 vCPU, 128 GB VPS

- A 64GB, 8vCPU database

- The landing page is on a Cloudflare worker

I am using PM2 to start a nodejs instance on each vCPU, so we have 24 instances of the API running behind the pm2 load balancer, itself behind the nginx reverse proxy

We're expecting around 50M-70M requests for next sunday, with most requests received around 9pm, we are expecting around 90k concurrent users

We are not using sockets, only HTTP requests (GET, POST, PUT)

I am looking for infrastructure tips to make sure that the API hold the traffic

Do you have any advice or tips on how I can scale the infrastructure and make sure that the API holds this kind of traffic ?

Thank you

I mainly work as a Node.js freelance dev. and for a client, I have to build a small mobile app (4 screens, very basic features: HTTP requests for login and signup, and just fetch and display data). The app might get updated with more features in the future

I don't know which tool to use for this, the 2 contenders are:

- React native: Not sure how mature it is, but there is a learning curve for sure, as I don't know react really well

- Cordova + Onsen UI: Cordova is pretty mature, but the app will be a webapp mimicking a native app, could feel awful to use

Do you have any opinion on those tools? Do you have any recommandation?
