OpenID: Now more powerful and easier to use! The OpenID+OAuth hybrid protocol (where a user can sign in with OpenID and grant an application access to their OAuth protected resources such as a contact list at the same time) is now supported by Google, Yahoo! and MySpace—this feels like OpenID finally coming of age.
Given the security issues with plugins in general and Google Chrome in particular, Google Chrome Frame running as a plugin has doubled the attach area for malware and malicious scripts. This is not a risk we would recommend our friends and families take.
Gmail for Mobile: Reducing Startup Latency. Cheeky iPhone optimisation trick—parsing 200 KB of JavaScript takes an iPhone 2.2 device 2.6 seconds, so Gmail embeds code components in /* comments */ in a script tag and evals them on demand later on when the features are needed.
More technical details about Google Chrome Frame. It’s implemented as a Browser Helper Object, uses IE’s cookies, history and password-remembering, includes the WebKit developer tools and appends “chromeframe” to the regular IE user agent string—though not apparently the Chrome Frame version itself.
PubSubHubbub for Google Alerts. “Think of it as a search API that tells *you* when it finds new results.”
Ask browser users, and they'll tell you the overwhelming reason why they can't upgrade to a more modern, standards-compliant browser is because their work won't let them. Ask IT departments why this is the case and they'll point to the six- to seven-figure costs of upgrading turn-of-the-century Intranets written to work in, and only in, Internet Explorer 6. Google have provided a way for websites to opt out of IE6 (and even IE7) support without requiring enterprise-wide, Intranet-breaking browser upgrades.
In the past, the Google Wave team has spent countless hours solely on improving the experience of running Google Wave in Internet Explorer. We could continue in this fashion, but using Google Chrome Frame instead lets us invest all that engineering time in more features for all our users, without leaving Internet Explorer users behind.
Introducing Google Chrome Frame. Here’s what Alex Russell has been up to at Google: An IE plugin (for 6, 7 and 8 on all Windows versions) which embeds the Google Chrome rendering engine—sites can then opt-in to using it by including a X-UA-Compatible meta tag. Seems to be aimed at corporate networks which mandate IE for badly written intranet applications—they can roll this out without retraining users to use another browser or breaking their existing in house apps.
Static Maps API v2. The new version of the Google Static Maps API (static images generated using arguments in a URL, no JavaScript required) adds support for paths, areas and automatically geocoding addresses to specify locations of markers and the centre of the map.
Hack Day tools for non-developers
We’re about to run our second internal hack day at the Guardian. The first was an enormous amount of fun and the second one looks set to be even more productive.
[... 920 words]AdSense for Feeds: What’s all the hubbub about PubSubHubbub? “Today we’re happy to announce initial support in FeedBurner for the PubSubHubbub protocol.”
Farewell to Mashup Editor. It’s not just Microsoft Popfly that’s shutting down—Google Mashup Editor will be gone in four weeks time (this was announced in January). You get to keep your code, but I don’t know enough about Mashup Editor to know if the code is usable once the system has shut down.
Google’s Chiller-less Data Center. Google are operating an outside data center in Belgium with no chillers (refrigeration units used to cool water, but at a high cost in energy) making “local weather forecasting a larger factor in its data center management”. On the 10 or so days of the year when Belgium is too warm, they can simply shut down the data center and shift the workload elsewhere.
Google Will Eat Itself. “We generate money by serving Google text advertisments on a network of hidden Websites. With this money we automatically buy Google shares. We buy Google via their own advertisment!”
App Engine outage postmortem. Interesting peek behind the scenes. The primary cause of the error was a bug in a GFS (Google File System) Master server caused by a MapReduce process sending a malformed filehandle, reminiscent of the error which took down S3 last year.
Codecs for <audio> and <video>. HTML 5 will not be requiring support for specific audio and video codecs—Ian Hickson explains why, in great detail. Short version: Apple won’t implement Theora due to lack of hardware support and an “uncertain patent landscape”, while open source browsers (Chromium and Mozilla) can’t support H.264 due to the cost of the licenses.
Google asked people in Times Square:“What is a browser?”. Stuff like this makes me despair for creating a secure web—what chance do people have of surfing safely if they don’t understand browsers, web sites, operating systems, DNS, URLs, SSL, certificates...
Dealing with election results data. Alf Eaton loaded the Guardian’s European election results spreadsheet in to Google’s new Fusion Tables tool.
Let's try to imagine what a Google Silverlight would have been. It would have been a fully open source product from Google, with a very liberal open source license (BSD or Apache). It would have all the technical specifications published openly. They would pledge to have the Silverlight VM interoperate with Javascript and HTML5. And a company like Zoho would have a ton of developers working on Google Silverlight based applications by now - as opposed to having exactly ZERO developers working on Microsoft Silverlight.
Announcing Google Maps API v3. Sounds like a complete rewrite, with performance as the key goal. Only a developer preview at the moment, but my favourite feature is that API keys are no longer required.
geocoders. A fifteen minute project extracted from something else I’m working on—an ultra simple Python API for geocoding a single string against Google, Yahoo! Placemaker, GeoNames and (thanks to Jacob) Yahoo! Geo’s web services.
Offline Processing on App Engine: a Look Ahead. A session at IO next week: “App Engine was designed to run request-driven web applications, although this will change in the coming year with the release of a number of offline computing components. In this session, we’ll explore the task queue/executor model of computation and some of the more interesting applications.”
Google container data center tour (on YouTube). 45,000 servers in 45 shipping containers, along with some serious looking plumbing.
And Now For Something Entire... Oooh! Shiny! Alex Russell on O3D, the new 3D browser plugin from Google that makes OpenGL accessible to JavaScript (and embeds V8 so performance won’t suck even on slower browsers).
London’s abandoned Underground Stations on Google Street View. “The network is littered with buildings that belonged to stations that closed their doors to the public because routes were changed and diverted, or because there was just too little traffic to make them viable. Here are some of the remnants of disused Underground stations that you can see on Google’s Street View of London.”
Reducing XSS by way of Automatic Context-Aware Escaping in Template Systems (via) The Google Online Security Blog reminds us that simply HTML-escaping everything isn’t enough—the type of escaping needed depends on the current markup context, for example variables inside JavaScript blocks should be escaped differently. Google’s open source Ctemplate library uses an HTML parser to keep track of the current context and apply the correct escaping function automatically.
Running Rhino and Helma NG on Google App Engine. Helma NG is a JavaScript web app framework, which now works on App Engine out of the box.
Using Scala with Google App Engine. Scala works, but I haven’t seen confirmation on actors yet (which are likely to break due to their dependency on threads).
Dynamic languages on Google App Engine—an overview. Ola Bini’s notes on exploring the new Java support for App Engine with the aim of getting JVM dynamic languages such as JRuby running. Restrictions include a complete lack of threads (which will make it hard to get Scala up and running), but JRuby trunk now works without modification.
App Engine: Scheduled Tasks With Cron. Cron tasks simply hit a URL on your application, and can be run as frequently as once a minute. They made up their own syntax, which much nicer than traditional unix cron.
