• Jaro-Winkler implementation in Ruby for User-Agent matching

  • #jaro-winkler
  • #ruby
  • #string matching

  Working in the mobile web, it's hard to keep up with the constant glut of devices on the market and their rapidly evolving capabilities. Of course, progressive enhancement is key; the markup you use in a mobile site should be minimal and look good without any CSS, JavaScript, or images, which is the worst-case. But we don't want to stop there; we want our sites to look as good as they can on as many mobile devices as possible. WURFL is here to help with that. A crowd-sourced database of mobile d

• Asynchronous Image Caching with the iPhone SDK

  • #iPhone
  • #Cocoa
  • #Objective-C

  Coming from the web world, I'm used to not having to think about all the functionality implicit in the humble HTML tag, including client-side resource caching and asynchronous loading. In fact, the browser will cache any resource sent with the appropriate HTTP response headers, but by far the most common use of this cache behavior on most websites is images of all kinds. So in building a couple of simple iPhone apps recently that display a list of search results retrieved from a server cal

• Cracking Supercollider

  • #oop

  • #documentation
  • #music synthesis
  • +2

  SuperCollider is an amazing language, if you are in the super genius club who can understand the extensive documentation or pursue graduate studies at CCRMA. I've been out of audio synth for a while, but recently found myself needing to apply a recursive delay line to an audio recording I'm working on for my music project, Midday Veil. SuperCollider dates from the mid-90's, and is thus a peer to Ruby, sharing influences like Smalltalk and Lisp. As languages go, it's pretty nice, though the compi

• Where are the JavaScript unittesting frameworks?

  • #JavaScript
  • #testing

  Now that JavaScript has been patched together into a number of promising server-side frameworks (Synergy, Jaxer, and, coming soon(ish), Rhino on Rails), JavaScript is really taking off as a potentially full-stack enterprise solution. One serious failing, however, seems to be the continued lack of decent developer support tools, the worst of which has got to be testing. Sure, there are a number of decent browser test automation frameworks out there: Selenium IDE WATIR JSUnit Sure, these are all g

  For all 2.3 of you out there reading this, I'd like to announce a new blog on "metaphysics?" so I can keep a clean sterile separation between work and life. My postings on this blog will continue to be exactly as infrequent as they have been since I started. Thank you.

• Strategies for Success (and other myths)

  • #Internet
  • #economics

  The writings and thoughts of Karl Marx and Friedrich Engels and orthodox Communism in general date themselves squarely between the Industrial Revolution and Darwin's historic Origins. The revolutionary implementation of Communism was doomed to failure, of course, because by the time it gained critical mass it was already obsolete; groups of humans can't be organized as machines are organized. Top-down mandates of economic equality don't work, because the system will always be more complex than e

• Easy Date Formatter

  • #JavaScript
  • #date formatter

  This should do the trick for most uses: /** * takes a string in form 'd/m/Y' * * d => day (2 digits, leading 0) * D => day (2 digits, no leading) * l => day (of week, text, 3 chars) * L => day (of week, text, full length) * * m => month (2 digits, leading 0) * M => month (2 digits, no leading 0) * f => month (text, 3 chars) * F => month (text, full length) * * y => year (2 digits) * Y => year (4 digits) * * g => hour (12hr, leading 0) * G => hour (12hr, no leading) * i => minute * s => second *

• Introducing CSSx

  • #CSS
  • #compiler
  • #cssx

  Sick of the lack of syntactic sugar for CSS? While many designers are fine with the simplicity of CSS, some developers managing large codebases (such as Zillow's still-terse 2500-line master.css) have been flailing for sanity. Enter CSSx, a syntax-enhancing compiler for CSS. It accepts all currently-valid CSS syntax, so you can use your current CSS chops unaltered, but adds variables and block nesting to the language. /* sample.cssx */ $red = #f00 /* a comment here*/; $block = { div { padding: 1

• Type-Converting Operator Considered Ridiculous

  • #JavaScript
  • #ecmascript
  • #second-guessing
  • #syntax

  I have come to question the wisdom of the type-converting == operator in JavaScript. The algorithm (defined in §11.9.3 of the ECMA-262 v3 spec) requires no fewer than 22 steps to execute, and produces such amazing intrasitivities as: >>> '0' == 0 true >>> 0 == '' true >>> '' == '0' false and random quirkiness such as: >>> ' \t\r\n' == 0 true but: >>> null == 0 false >>> null == false false >>> null == '' false >>> null == undefined true Do these behaviors strike anyone else as, well, a bit off?

• All the Code Security You Need

  Lots of beginning JS coders seem to have this idea that the web is all about having your cake and eating it too. I want to participate in the glorious Internet revolution, I just don't want to share my ideas or information with anybody else. I'm writing rich internet applications that are so great, just so unique, that I want to make sure nobody else can possibly look at my code and steal all those great juicy super-awesome proprietary ideas I've got. And maybe, just for bragging rights, I want

• The Problem with SlickSpeed

  • #CSS
  • #JavaScript
  • #css queries

  For the past month or so, there's been a lot of noise about the SlickSpeed Selectors Test Suite. Since I'm in the market for a good selector engine for Zillow, and since it's a bit of a rite of passage (a front-end web dev's equivalent of compiler authoring?), I wrote my own, to see how well I could do and to see how it stacks up to the rest. So of course, I modified the suite (under its MIT license) to test my little attempt as well. I was pleased with my initial results, but found the test doc

  • #Google

  As we all know, Google has great power. It's power that comes from the masses: utilizing and channeling the activities, ideas and opinions of millions via the Web. All that information and trust capital can be a powerful tool for sustaining an environment that encourages democracy. Or not. Update: Apparently now, for some at Google, democracy is available to the highest bidder. But the more important point, since I doubt that too many people care about my personal opinion, is that advertising is

• Web-Native UX

  • #usability

  I'd like to address something many in the User Experience community would rather avoid, since many times it may interfere with deploying the latest cool widget or Ajax technique that comes down the pike. I want to talk about User Experience Consistency and the web. Because while standards bodies have come into being to coordinate the development of the cornerstone technologies from which we build interfaces, and any web developer worth her salt pays attention to valid, semantic markup and the ve

• The Blogging Professional

  It is a melancholy experience for a professional mathematician to find himself writing about mathematics. The function of a mathematician is to do something, to prove new theorems, to add to mathematics, and not to talk about what he or other mathematicians have done. Statesmen despise publicists, painters despise art-critics, and physiologists, physicists, or mathematicians have usually similar feelings: there is no scorn more profound, or on the whole more justifiable, than that of the men who

• Crockford's revisions to ECMAScript

  • #ecmascript

  The ECMAScript standard is undergoing growing pains right now, and for the first time since 1999, it looks like major revisions to the language may take effect soon. Douglas Crockford has recommendations of his own. While I don't have any strong feelings about the new features he requests (they can mostly be implemented in the JavaScript we already have), his Corrections are mostly sane things that will remove a lot of the suckiness from the current standard: Reserved words Standardize implement

• Code Modularization and CSS Queries

  • #JavaScript
  • #HTML
  • #Code
  • #history

  On his personal blog, YAHOO! front-end engineer Nicholas Zakas takes on the prevalence of the CSS query engine in client-side JavaScript libraries. The flexibility of some other quick syntax shorthand for accessing HTML elements and describing structure without using the conventional DOM methods has always appealed to me, so I wasn't sure what he was missing. Granted, the recent proliferation of JS libraries in general (and query engines in particular) has been rather excessive, no doubt trackin
