FOWA London—Beyond GoogleMaps. Andrew Turner’s talk at FOWA was the most information dense presentation I’ve ever seen, and discussed a huge number of cool geo projects that I’d never previously heard of. Andrew links to the full slides and video, well worth a watch.

Conditional classnames. Yahoo!’s internal coding standards still recommend CSS hacks over conditional comments because a separate stylesheet for IE imposes an additional HTTP request. Paul Hammond points out that you can use conditional comments to write out an extra class=“ie” attribute on the body element and use that to target the IE specific fixes in your stylesheets.

US shifts Visa Waiver Program authorization to Internet—Yahoo! News (via) If you’re a European travelling to the US from January 2009 you’ll need to fill out the online equivalent of an I-94W (the green form you get given on the plane) in advance. This is going to catch out a lot of people.

Best Practices for OAuth with Fire Eagle. “We insist that you must NOT use embedded rendering controls to present the OAuth process with Yahoo! and Fire Eagle”—that’s a clear nod towards the iPhone development community.

Go Get Yer Shiny New Yahoo Profile... And Make Some Connections! I’m surprised to see Yahoo! going with mutual friendships as the core of their new social platform—I’ve personally found social sites which support a one-way “follow” relationship far more useful.

Data Scraping Wikipedia with Google Spreadsheets. I hadn’t played with =importHTML in Google spreadsheets, which lets you suck in data from an HTML table or list somewhere on the web. This tutorial takes it further, bringing Wikipedia, Yahoo! Pipes and KML in to the mix.

A Million-user Comet Application with Mochiweb, Part 1. Richard Jones explores Mochiweb, Erlang and linux kernel tuning for building a high performance comet server. Does this mean real-time web features are coming to last.fm?

View your FriendFeed in real-time. FriendFeed become the latest site to enable real-time updates using the long-polling variant of Comet. The real-time Web was something of a theme at this year’s FOWA, with talks on message queues, XMPP and scaling Comet at Meebo.

Page Inlink Analyzer (via) Here’s why I’m so keen on JSONP APIs—Eric Miraglia’s tool fires off dozens of cross-domain JSON requests to pull together information about inbound links to your site from Yahoo! Site Explorer and del.icio.us. I imagine it would have been uneconomic for him to provide the tool if it had to proxy every request through his own server.

Yahoo! Releases OpenID Research. Extremely valuable research, conducted with a group of typical Yahoo! users. OpenIDs usability remains bad, and if we don’t get it right soon something centralised like Facebook Connect will take over and the Web will stop being open.

Minimal nginx conf to split get/post requests. Interesting idea for master-slave replication balancing where GET v.s. POST is load-balanced by nginx, presumably to different backend servers that are configured to talk to either a slave or a master. This won’t deal very will with replication lag though—you really want a user’s session to be bound to the master server for the next few GET requests after data is modified to ensure they see the effects of their updates. UPDATE: Amit fixed my complaint with a neat hack based around a cookie with a max age of 10 seconds.

Browser Paint Events. The latest Firefox nightlies include a new MozAfterPaint event which fires after a portion of the page has been redrawn and provides co-ordinates of the affected rectangle. John Resig provides a neat bookmarklet that uses the new event to visualise repainting operations.

Versioning REST Web Services. Peter Williams suggests using a vendor MIME media type in the Accept header to specify a required API version, because embedding the API version in the URL itself leads to a single resource ending up with many different URLs, one for each API version.

Videos from FOWA 2008. The Carsonified team have a scarily fast turnaround on the videos from this year’s Future of Web Apps. Most of yesterday’s talks are already available to watch online, as a full talk or the edited highlight reel.

XHTML—myths and reality. Useful overview of XHTML from Tina Holmboe of the W3C’s XHTML Working Group, which suggests considering HTML 4.01 strict unless you need mixed namespaces for things like MathML. I’ve been storing this blog’s content as XHTML but serving as HTML for several years now.

Clickjacking and NoScript (via) NoScript CAN protect against clickjacking, but only if you enable the “Plugins|Forbid IFRAME” option.

Dealing with UI redress vulnerabilities inherent to the current web (via) The best explanation of clickjacking I’ve seen yet, complete with discussion of a number of non-ideal potential solutions. It looks like frame busting JavaScript will defeat it, but only for users who have JavaScript enabled—which means that in this case extensions like NoScript actually make you less safe. UPDATE: NoScript is smarter than I thought; see the comments.
