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.

BOSH Links: Why and How

Audience: anyone in the BOSH ecosystem, whether you work on something open-source or proprietary

"BOSH Links" is a feature which simplifies how data is shared between BOSH-deployed jobs that need to collaborate with one another (e.g. a web server and its backing database). Like many BOSH things, the whole "BOSH Links" thing can seem counter-intuitive at first, and it may not be clear why things are the way they are. This note hopes to show some of the powerful benefits of BOSH Links, and provide examples and explanations that make things more intuitive.

Why?
BASIC: A simple problem statement
BASIC: Putting the puzzle pieces together
ADVANCED: But what about...
