Clarke’s three laws of prediction

From Wikipedia’s “Clarke’s three laws” (2 November 2006):
Arthur C. Clarke formulated the following three “laws” of prediction:
1. When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
2. The only way of discovering the limits of the possible [...]

How to start a startup

From Paul Graham’s “Why Smart People Have Bad Ideas” (April 2005):
Trevor Blackwell presents the following recipe for a startup: “Watch people who have money to spend, see what they’re wasting their time on, cook up a solution, and try selling it to them. It’s surprising how small a problem can be and still provide a [...]

Which is better: products or services?

From Paul Graham’s “Why Smart People Have Bad Ideas” (April 2005):
It’s much easier to sell services than a product, just as it’s easier to make a living playing at weddings than by selling recordings. But the margins are greater on products.

What successful startups need

From Paul Graham’s “How to Start a Startup” (March 2005):
You need three things to create a successful startup: to start with good people, to make something customers actually want, and to spend as little money as possible. Most startups that fail do it because they fail at one of these. A startup that does all [...]

From “Beauty Is Our Business: A Birthday Salute to Edsger W. Dijkstra“:

Failure every 30 years produces better design

From The New York Times‘ “Form Follows Function. Now Go Out and Cut the Grass.“:
Failure, [Henry] Petroski shows, works. Or rather, engineers only learn from things that fail: bridges that collapse, software that crashes, spacecraft that explode. Everything that is designed fails, and everything that fails leads to better design. Next time at least that [...]

Why infosec is so hard

From Noam Eppel’s “Security Absurdity: The Complete, Unquestionable, And Total Failure of Information Security“:
A cyber-criminal only needs to identify a single vulnerability in a system’s defenses in order to breach its security. However, information security professionals need to identify every single vulnerability and potential risk and come up with suitable and practical fix or mitigation [...]

Paul Graham’s lessons for startups

From Paul Graham’s “The Hardest Lessons for Startups to Learn“:
1. Release Early.
The thing I probably repeat most is this recipe for a startup: get a version 1 out fast, then improve it based on users’ reactions.
By “release early” I don’t mean you should release something full of bugs, but that you should release something minimal. [...]

Human life & wasted time

From Paul Graham’s “The Hardest Lessons for Startups to Learn“:
We take it for granted most of the time, but human life is fairly miraculous. It is also palpably short. You’re given this marvellous thing, and then poof, it’s taken away. You can see why people invent gods to explain it. But even to people who [...]

Architecture & the quality without a name

From Brian Hayes’ “The Post-OOP Paradigm“:
Christopher Alexander [a bricks-and-steel architect] is known for the enigmatic thesis that well-designed buildings and towns must have “the quality without a name.” He explains: “The fact that this quality cannot be named does not mean that it is vague or imprecise. It is impossible to name because it is [...]

MTBU: Maximum Time to Belly Up

From The Register’s “How ATM fraud nearly brought down British banking“:
And there wasn’t time for the banks to fix the problem if anyone went public with it. Their MTBU was too short. MTBU? That’s “Maximum Time to Belly Up”, as coined by the majestic Donn Parker of Stanford Research Institute. He found that businesses that [...]

kanso and shizen and presentations

From Garr Reynolds’ “Gates, Jobs, & the Zen aesthetic“:

A key tenet of the Zen aesthetic is kanso or simplicity. In the kanso concept beauty, grace, and visual elegance are achieved by elimination and omission. Says artist, designer and architect, Dr. Koichi Kawana, “Simplicity means the achievement of maximum effect with minimum means.” …
The aesthetic concept [...]

Good advice re: contracts

From Matt Asay’s “Words to live by“:
This was one of the few things I learned at Stanford Law School: you never want to have to enforce a contract, because the clear interpretation of a contract becomes much less clear the minute both sides stop agreeing on that interpretation.

How to know if you should worry

From Bruce Schneier’s “Should Terrorism be Reported in the News?” in Crypto-Gram (15 May 2005):
One of the things I routinely tell people is that if it’s in the news, don’t worry about it. By definition, “news” means that it hardly ever happens. If a risk is in the news, then it’s probably not worth worrying [...]

Breaking up is like a cold

From Ben Jones’ Benblog, in February 2003:
Ben on breaking up with a girl: “Archer said last night that getting over a girl is like getting over a cold. You just wake up one day, after the lingering affects are over, and vaguely remember that you were sick.”
