• I am not qualified to comment on the merits of these technologies as currencies or mechanisms for agreeing contracts. However, from a data systems point of view they contain some interesting ideas. Essentially, they are distributed databases, with a data model and transaction mechanism, in which different replicas can be hosted by mutually untrusting organizations. The replicas continually check each other’s integrity and use a consensus protocol to agree on the transactions that should be executed.
• Outside of the hype of cryptocurrencies, certificate transparency is a security technology that relies on Merkle trees to check the validity of TLS/SSL certificates
• Let us replace the word data with Surveilance - “In our surveillance-driven organization we collect real-time surveillance streams and store them in our surveillance warehouse. Our surveillance scientists use advanced analytics and surveillance processing in order to derive new insights.”

Rich Hickey on becoming a better developer

Sorry, I have to disagree with the entire premise here.

A wide variety of experiences might lead to well-roundedness, but not to greatness, nor even goodness. By constantly switching from one thing to another you are always reaching above your comfort zone, yes, but doing so by resetting your skill and knowledge level to zero.

Mastery comes from a combination of at least several of the following:

const container = document.evaluate('//a', document, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE , null)
const items = Array.from(Array(container.snapshotLength).keys())
const _links = items.map(i => container.snapshotItem(i).innerHTML).filter(text => text.indexOf("http")!=-1)
const links = _links.sort().filter((e,i,a) => a.indexOf(e)==i)
console.log("Unique links \n" + links.join("\n"))
let map = {}
_links.sort().map(link => link.substring(0,100)).forEach(link => map[link] = (map[link] || 0) + 1)
Object.entries(map).sort(kv => kv[1]).map(kv =>  kv[1].toString().padEnd(4) + kv[0]).join("\n")
