September 2012 A startup is a company designed to grow fast. Being newly founded does not in itself make a company a startup. Nor is it necessary for a startup to work on technology, or take venture funding, or have some sort of "exit." The only essential thing is growth. Everything else we associate with startups…
November 2012 The way to get startup ideas is not to try to think of startup ideas. It's to look for problems, preferably problems you have yourself. The very best startup ideas tend to have three things in common: they're something the founders themselves want, that they themselves can build, and that few others…
March 2012 One of the more surprising things I've noticed while working on Y Combinator is how frightening the most ambitious startup ideas are. In this essay I'm going to demonstrate this phenomenon by describing some. Any one of them could make you a billionaire. That might sound like an attractive prospect, and yet…
January 2012 There are great startup ideas lying around unexploited right under our noses. One reason we don't see them is a phenomenon I call schlep blindness . Schlep was originally a Yiddish word but has passed into general use in the US. It means a tedious, unpleasant task. No one likes schleps, but hackers…
July 2004 (This essay is derived from a talk at Oscon 2004.) A few months ago I finished a new book , and in reviews I keep noticing words like "provocative'' and "controversial.'' To say nothing of "idiotic.'' I didn't mean to make the book controversial. I was trying to make it efficient. I didn't want to waste…

Khan Academy recently launched an online environment for learning to program. It offers a set of tutorials based on the JavaScript and Processing languages, and features a "live coding" environment, where the program's output updates as the programmer types.
(This article has been translated into Spanish (PDF, with some additions) by Jorge Amado Soria Ramirez — thanks!) Preface I’m cranky. I complain about a lot of things. There’s a lot in the world of technology I don’t like, and that’s really to be expected—programming is a hilariously young discipline, and none of us
September 2012 I've done several types of work over the years but I don't know another as counterintuitive as startup investing. The two most important things to understand about startup investing, as a business, are (1) that effectively all the returns are concentrated in a few big winners, and (2) that the best…

Ever wonder about that mysterious Content-Type tag? You know, the one you’re supposed to put in HTML and you never quite know what it should be? Did you ever get an email from your friends in…
Generic data structures (vectors, queues, maps, trees, and so on) seem to be the hot topic if you are evaluating a new language. One of the most frequent questions we've had about Go is where the generics are. It seems like there are three basic approaches to generics:

Mail::RFC822::Address is a Perl module to validate email addresses according to the RFC 822 grammar. It provides the same functionality as RFC::RFC822::Address, but uses Perl regular expressions rather that the Parse::RecDescent parser. This means that the module is much faster to load as it does not need to compile…
Better beware of notions like genius and inspiration; they are a sort of magic wand and should be used sparingly by anybody who wants to see things clearly. (José Ortega y Gasset, “Notes on t…
"I'm going to beat grep by thirty percent!" I confidently crow to anyone who would listen, those foolish enough to enter my office. And my girlfriend too, who's contractually obligated to pay attention to everything I say.
Crypteto has a 49,152-bit symmetric key: The most important issue of any encryption product is the ‘bit key strength’. To date the strongest known algorithm has a 448-bit key. Crypteto now offers a 49,152-bit key. This means that for every extra 1 bit increase that Crypteto has over its competition makes it 100%…
This is a big deal: On May 13th, 2008 the Debian project announced that Luciano Bello found an interesting vulnerability in the OpenSSL package they were distributing. The bug in question was caused by the removal of the following line of code from md_rand.c MD_Update(&m,buf,j); [ .. ] MD_Update(&m,buf,j); /* purify…

In 2007, I met Philip Wadler at a conference, who mentioned to me that he wanted to teach lambda calculus to his eight-year-old children.

I spend a lot of my time (easily over 8 hours a day) at a keyboard. As you might have guessed from my previous entries about Vim and Mutt I'm not averse to spending a few hours to improve an environment I'm going to be spending tens of thousands of hours in over the next few years, so it shouldn't be a shock that my…
