Hello everyone!

I need an advice. I work on a web app, that needs to send PNG images to users based on their achievements. The easiest way to do that is to construct an HTML that contains all the information, make a screenshot of it and finally upload it to the server. But this solution is extremely not optimal.

So I'm curious how to implement the same logic, but without frontend involvement in terms of image generation. I know that there are many commercial libs and services for that, but maybe there is some open-source more or less good libs for that.

I'm fine to work with Java, Scala, NodeJS or Golang.

Any advice is welcome!

Let's assume that some BTC wallet has following transaction history:

2015: received 3 BTC

2016: received 1 BTC

2017: received 1 BTC

2018: sent 1 BTC

2019: received 2 BTC

In this case the number is 7 BTC

Do you know any online service which can do such sort of calculations?

This message is mostly to instagramers :)

Recently I noticed, that every time I post a photo on Instagram, I always compare how many likes it collects, comparing to the same-topic photos in my followers network. And what is interesting I like to compare numbers :D

Does anybody experience the same sort of implicit competition?
