Using Metadata to Find Paul Revere
London, 1772. I have been asked by my superiors to give a brief demonstration of the surprising effectiveness of even the simplest techniques of the new-fangled Social Networke Analysis in the pursuit of those who would seek to undermine the liberty enjoyed by His Majesty’s subjects. This is in connection with the…

Win32 Is the Only Stable ABI on Linux?
In the ELF format there are two ways of providing a hash table of symbols. DT_HASH and DT_GNU_HASH . The first one is part of SYSV generic ABI and is well documented and marked as mandatory. DT_GNU_HASH is a newer, smaller, and faster replacement that is not documented , implemented in a few places (Glibc, GNU ld…

Rewriting Reddit (2005)
2012 note: This article was first published in 2005. After it was published, Django launched a RemovingTheMagic project to address some of my criticisms (though personally I still find it unusable), web.py inspired FriendFeed’s tornado.web and Google’s gae.webapp and others (though I still prefer web.py), and this…

A Road to Common Lisp
I've gotten a bunch of emails asking for advice on how to learn Common Lisp in the present day. I decided to write down all the advice I've been giving through email and social media posts in the hopes that someone might find it useful.

Why Static Websites Need HTTPS
It was Jan last year that I suggested HTTPS adoption had passed the "tipping point" [https://www.troyhunt.com/https-adoption-has-reached-the-tipping-point/], that is, it had passed the moment of critical mass [https://en.wikipedia.org/wiki/The_Tipping_Point] and as I said at the

Be Relentlessly Resourceful
March 2009 A couple days ago I finally got being a good startup founder down to two words: relentlessly resourceful. Till then the best I'd managed was to get the opposite quality down to one: hapless. Most dictionaries say hapless means unlucky. But the dictionaries are not doing a very good job. A team that outplays…

Kill Math
The power to understand and predict the quantities of the world should not be restricted to those with a freakish knack for manipulating abstract symbols.

The Fermi Paradox
The Fermi Paradox: There should be 100,000 intelligent alien civilizations in our galaxy — so why haven't we found any of them?

Git from the Bottom Up (2008)
Welcome to the world of Git. I hope this document will help to advance your understanding of this powerful content tracking system, and reveal a bit of the simplicity underlying it — however dizzying its array of options may seem from the outside.

Advantages of monolithic version control
Someone : Did you hear that Facebook/Google uses a giant monorepo? WTF! Me : Yeah! It's really convenient, don't you think? Someone : That's THE MOST RIDICULOUS THING I've ever heard. Don't FB and Google know what a terrible idea it is to put all your code in a single repo? Me : I think engineers at FB and Google are…

Alligator Eggs
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.

Tcl the Misunderstood (2006)
In an article recently linked from reddit entitled Tour de Babel you can read (among lots of other nonsense): Heck, people still use Tcl as an embedded interpreter, even though Python is far superior to Tcl in every conceivable way -- except, that is, for the frost thing.

Julia is awesome, but..
Here's a language that gives near-C performance that feels like Python or Ruby with optional type annotations (that you can feed to one of two static analysis tools ) that has good support for macros plus decent-ish support for FP, plus a lot more. What's not to like? I'm mostly not going to talk about how great Julia…

The Anatomy of Determination
September 2009 Like all investors, we spend a lot of time trying to learn how to predict which startups will succeed. We probably spend more time thinking about it than most, because we invest the earliest. Prediction is usually all we have to rely on. We learned quickly that the most important predictor of success is…

The Git Parable (building a Git-like system from the ground up)
Git is a simple, but extremely powerful system. Most people try to teach Git by demonstrating a few dozen commands and then yelling “tadaaaaa.” I believe this method is flawed. Such a treatment may leave you with the ability to use Git to perform simple tasks, but the Git commands will still feel like magical…

(An ((Even Better) Lisp) Interpreter (in Python))
The tokens #t and #f are the True and False literals, respectively. The single quote mark serves to quote the following expression. The syntax ' exp is completely equivalent to (quote exp ) . The backquote character ` is called quasiquote in Scheme; it is similar to ' except that within a quasiquoted expression, the…
