  Ten things I want Siri to be able to do for me

Now that I've had my iPhone 4S for a couple of days, I'm amazed with what Siri can do. I've asked a number of questions -- real ones, not questions like "What is the meaning of life?" -- and have been totally impressed with how my interaction with the iPhone has changed. But there are more things I'd love to be able to do with Siri, which is the reason for this post.Everyone should understand that Siri is currently a beta product from Apple.

  Transparency in Cloud Services

37signals recently launched public “Uptime Reports” for their applications (announcement). The reaction on Hacker News was rather tepid, but I think it’s a positive development, and I applaud 37signals for stepping forward. Reliability of cloud applications is a real concern, and there’s not nearly enough hard data out there. Not all products are equally reliable; even within 37signals, the new reports show a 3:1 variation in downtime across apps. That said, ...

  Valid JavaScript variable names

Did you know var π = Math.PI; is syntactically valid JavaScript? I thought this was pretty cool, so I decided to look into which Unicode glyphs are allowed in JavaScript variable names, or identifiers as the ECMAScript specification calls them. Reserved words The ECMAScript 5.1 spec says: An Identifier is an IdentifierName that is not a ReservedWord.

  Designing Fun

What is “Fun?”“I’ll know it when I see it.”In 1964, in Jacobellis v. Ohio, the US Supreme Court needed to decide whether the state of Ohio could ban a film it called “obscene”—a concept people understood but were hard-pressed to define. Justice Potter Stewart, in his concurring opinion, wrote: “I shall not today attempt further to define the kinds of material I understand to be embraced within that shorthand description; and perhaps I ...

  How Duff’s Device Works

I like C, but I have to admit that, sometimes, “The Old Man of Programming” can be a bit of a killjoy. This is one of the most exciting eras in computer history, but lately, C’s acting like he doesn’t evenwant to have a good time. While the cool kids like Ruby and Haskell are living it up, C’s over in the corner obsessing over bits and bytes and memory alignment and pointers and the stack and machine architecture and unreachable allocations and multiple indi...
