SparseCategoricalCrossentropy with class weights for Keras/Tensorflow 2

Handshake airdrop for github users.

Had 15 github followers in 2019? You can get about $4kAUD of crypto for minimal effort.

Explain this scam

That's legitimately a good default position to hold, however, in this case, the free money is a function of time, and not only charity.

In February 2020, in order to promote Handshake (HNS) to developers, an airdrop was offered to any Github user with more than 15 followers. The Airdrop would give you 4246HNS, at the time worth around at $0.08USD per coin, for a total of $339.68USD, pretty generous!

Today, 4246HNS is worth around $4000 dollarydoos, and there are plenty of github users who haven't claimed theirs.
