Reference excerpt

Sean Hastings (born 1969) is an American entrepreneur, cypherpunk author, and security expert.

Work In 1997, Hastings worked on cryptographic protocols and tools free of U.S. cryptographic export restrictions with Vincent Cate, who started the International Conference on Financial Cryptography in Anguilla that same year. Hastings founded HavenCo in 2000, originally incorporating in his country of residence, Anguilla, before a second incorporation in the Channel Islands. Hastings was the CEO; other co-founders included Ryan Lackey and Sameer Parekh. Immediately following its public launch, HavenCo was the subject of a great deal of press coverage, including Hastings' appearance, along with several cofounders and the "royal family" of the self-proclaimed, unrecognized micronation of Sealand, on the cover of Wired's July 2000 issue, before the company was entirely nationalised by the government of Sealand in 2002, after commercial failure and mounting tensions. In 2002, Hastings began work on seasteading with Patri Friedman, a project aimed at building floating communities free from the restrictions of current governments. This collaboration continued through 2009, including a talk by Hastings at the Seasteading Institute's annual conference. Hastings is the cofounder, with Eric S. Raymond, of Green-Span, an open source infrastructure for trust and reputation management, begun in March 2009. Hastings is also the author, with Paul Rosenberg, of a book, God Wants You Dead (Vera Verba, 2007; ISBN 978-0-9796011-1-8) which takes a look at the lighter side of atheism and anarchy, and was executive producer and an actor for The Last Generation to Die a short film about near future immortality technology.

Worked examples

Example 1 — a first encounter with Sean Hastings

Start with the simplest possible case. Write down what Sean Hastings claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sean Hastings before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sean Hastings ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sean Hastings

In research: Sean Hastings appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Sean Hastings in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Sean Hastings is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1969 births, 21st-century anarchists, American atheists, so understanding it makes those chapters shorter.
In everyday life: Look for Sean Hastings outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
