Looks like Google is determined to make maintaining open source extensions for Chrome/Chromium an utterly demoralizing experience.

Updates to extensions that have been published for years being rejected for critical bugfixes with robo-rejection emails, no way to reach a human. One forum, not really advertised anywhere, is getting flooded with developer requests:

Summarised some results from a notebook that I use to play with the Covid19 data. It includes a simple prediction model for number of cases:

Most countries are still moving along the same exponential with coronavirus.

How do we learn about products and businesses or governments about us? How can we improve it?

4 reasons for leaving proprietary review platforms behind, and 1 tool to make it happen. Check out our release blog post for the Mangrove beta web app:

Just released the first building blocks to make integration with Mangrove easy: 1) JS client library & 2) API documentation These two allow you to generate, submit, and retrieve reviews from the open dataset.

We just released the Mangrove demo web app 🚀

You can read and write reviews and upload pictures for restaurants, hotels, touristic sites and other places on the map, as well as for companies, websites and books.

Join the ecosystem for and integrate Mangrove into your application or website.

PlantingSpace is now up and running! All our initial projects are published on our website, and the company is set up. Visit us at
