Designing Web APIs - Twitter Learnings

alexbarnett — Thu, 01 May 2008 11:08:00 GMT

Although I made it to Web 2.0 Expo in San Francisco last week, I didn't make it to a session Matt McAlister blogged about by Twitter’s Alex Payne and Michael Migurski of Stamen Design who presented learnings from the perspective of an API provider.

But I can see the slide deck discussing the Twitter API and so can you:

Among the dynamos, My Data and advice for startups.

SaaS / DaaS / WaaS (Whatever As a Service) and Mashups

Nick Carr quotes Henry Adams in Among the dynamos

“One lingered long among the dynamos,” he wrote, “for they were new, and they gave to history a new phase.

Pointing to SaaS Platforms trends, Clive Keyte write about "SaaS Management Platforms"

"Force.com is not on it’s own offering ‘cloud development facilities for SaaS applications though, there are a plethora of smaller companies entering into the fray including Bungee Connect"

Among the dynamos indeed...

And SaaS by the numbers: Salesforce.com: 24 Billion API Calls So Far

"This statistic along with others like 130 million transactions daily, 61,200 custom applications, and 750 AppExchange apps"

Bray Forrest informs us even Your Car Gets An API

"At the end of the month the Dash will get a RESTful API. At the user's initiative lat/long coordinates can be sent to a server. The Dash will consume a GeoRSS feed. This is just the first release. In the future they may add HTML pages, search and even the ability to poll. The device I saw did not have any API-driven apps loaded, but I can imagine great ones (update my location and finding out who from my YASN contacts are nearby)."

So what will we do with all these APIs? Mashups of course! What is a MashUp?

"Potatoes + beans + a little bit of beef + pork, and then you pour Smithwicks over the top of it."

Ah...Microsoft Research project alert: Rotunda: Profiling the Cloud

"the goal of the project is to be able to profile the performance of a Web application from the time a user clicks on a link and triggers an event in the browser—which triggers a database lookup—through each point of the resolution of the transaction."

Sounds a lot like Bungee Connect instrumentation designed to measure every transactions from user's browser interactions and server-side roundtrips, through to the app's service calls, triggers, events, response times, etc...You see, our business model demands we and our developers know this...we have this today :-)

My Data

The UK gets some relief from the ID Card madness, for a while anyway...turns out National ID cards scheme will delayed until 2012:

"The Government’s national identity card scheme was “in the intensive care ward” after leaked documents showed plans to issue UK citizens with the cards have been delayed until after the next election."

Phew! Seeing stories like this seems to be knocking sense to those who are living in cloud-cuckoo land...

On the other end of the "my data" equation: cries of "we want our data, when we want it and where we want it" are getting heard...

Here's video intro to DataPortability.org initiative: DataPortability - Connect, Control, Share, Remix.

"DataPortability gathers existing open standards into a blueprint for a social, open, remixable web where your online identity, media, contacts and content can follow you wherever you go."

Niall Kennedy's take on Data Portability, Authentication, and Authorization.

"Data authorization is the first step in data portability."

Enter OpenID and OAuth.

How will DataPortability.org keep from being hijacked by Microsoft? Now Microsoft has joined the fray, so does the inevitable questioning begin:

"So is the nascent DataPortability.org group at such risk from Redmond? Not according to a source inside the group."

News of Last.fm's on demand since CBS's acquisition hit the mainstream tech media yesterday. But what next? CBS Will Try To Convert Last.FM Acquisition To Video Value

“One of the reasons we liked the idea of buying it is, if we can develop a great social networking site around this music content, why couldn’t this extend in to entertainment, in to news sports, all businesses that we’re in"

Kaching!

Martin Plaehn's Quick Hits: Do's and Dont's of Entrepreneurship. 16 pieces of advice for start-ups.

"6. Do always accumulate choice; two by definition, three of four is better; then make decisions and have a back-up"

More Investments Into Open Source

News that Alfresco Gets Another $9M for Open Source Content Management

"Alfresco Software, an open source content management alternative to software created for large companies, has received an additional $9 million in a third round of financing, led by SAP Ventures and existing investors Accel Partners and Mayfield Fund"

However, not all the shareholders are happy with the Alfresco deal...Matt Asay wrote in New open source venture funding and the importance of SAP Ventures and Intel Capital

"But since we didn't need the money (not even remotely) and I didn't want the dilution, it's not my favorite news of the day."

Amen to that.

Uh Oh...

What I'm reading...

alexbarnett — Mon, 21 Jan 2008 17:06:00 GMT

There are a whole bunch of interesting posts / stuff I find on the net that I bookmark on del.icio.us (at least, I think they are interesting). Over the years I've been experimenting with different ways of sharing these with you. My most recent solution has been to include my del.icio.us links within my feed as seperate items. The problem with this approach is I haven't had a permalinked way of publishing these to my blog with a way to easily edit prior to publishing...also, having the daily summaries del.icio.us format in a feed is lame.

So I going to try something new. Instead of having the daily del.icio.us link summaries published as RSS items within my Feedburner feed, I'm going to publish these as blog posts. It should make things more economical from the consumption point of view (I don't think the "Links for 2008-01-20 [del.icio.us]" blah blah feed item titles are pretty). To do this, I have:

disabled the del.icio.us feed syndication from Feedburner (the Link Splicer)
have installed Josh Leggard's Insert Feed Content plugin for Windows Live Writer - this lets me populate a draft blog post with the latest items from any feed (my del.icio.us feed in this case - I'll still use the service for bookmarking) that I can then include / edit / add more commentary before I post to my blog - along with a custom post title.

Better me thinks. I like Harry Pierson's and Assaf's Labnotes style of providing links with commentary...over time I hope to emulate these.

So here goes - this first effort will be larger than future posts like this...shorter in the future.

Podcast interviews - smart people in the world of the web

alexbarnett — Sun, 20 Jan 2008 15:41:00 GMT

One of the fun parts of my job at Bungee Labs is to partner up with Ted and interview some smart people in the world of the web. We publish these as a podcast series (the Bungee Line - podcast feed here) over on the BCDN blog.

If you have ideas about someone you think we should interview, let me know! We're focusing on topics we think web developers might be interested in the worlds of software as a service and web app development, in particular profiling web apis. Related topics are good too.

I've listed out below our most recent podcasts below...plenty more in the works (previous podcasts are listed here). Hope you like :-)

Alan Lewis on eBay Desktop and eBay APIs

"As product manager for eBay Desktop, Alan Lewis relies on the same web APIs that eBay makes available to all developers. In this edition of the Bungee Line, Alan tells us about what the eBay Desktop is, how it came about, and various details about eBay’s developer program and web APIs. We ask Alan about eBay’s position Oauth and on open source."

Toby Segaran on “Programming Collective Intelligence”

"Since the publication of his O’Reilly book Programming Collective Intelligence: Building Smart Web 2.0 Applications, Toby Segaran has become well noted for his ability to explain easily-understandable algorithms for the kind of deeply complex problems involved in social applications. Toby joins Alex and Ted to discuss some of the high-level concepts that he tackles in his book."

Jon Aizen of Dapper.net

"Jon Aizen joins Alex and Ted to explain how Dapper.net provides a no-fee tool for making almost any structured web site data accessible via a REST API. In a past life, Jon was involved in creating The Internet Archive. Jon also helps the Bungee Line introduce romantic intrigue into the podcast.

Punditry Alert! At the end of this show, Ted and Alex speculate a bit about Android, Google’s open source mobile device platform, the Apache License, and whether Robert Love is involved. Please consider this as another demonstration of Ted’s idiocy, brought to you by the Bungee Line."

Jeff Barr on Amazon Web Services (Part 2)

"In part 2 of our interview with Amazon Web Services evangelist Jeff Barr, Alex and Ted ask Jeff about Flexible Payment Service, virtual user group meetings in Second Life, the Startup Project, and pry at Jeff’s views of possible futures of technologies that developers might anticipate."

Jeff Barr on Amazon Web Services (Part 1)

"Developer evangelist for Amazon Web Services, Jeff Barr tells Alex and Ted about how he became a native Amazonian, his recent visit to “The Business of API’s Conference,” and a bunch of stuff on Amazon Web Services, including: Mechanical Turk, EC2, and S3. Additionally, Jeff explains the newly announced S3 Service Level Agreement*."

OAuth Podcast

alexbarnett — Sat, 03 Nov 2007 14:45:00 GMT

Chris Messina (aka FactoryJoe), Larry Halff (of Ma.gnolia) and Eran Hammer-Lahav accepted our invitation to join Ted and me and discuss OAuth in our latest Bungee Line podcast.

What is OAuth? From OAuth Getting Started - Part 1, here's the jist of it:

"OAuth allows you to share your private resources (photos, videos, contact list, bank accounts) stored on one site with another site without having to hand out your username and password.

...Users don’t care about protocols and standards – they care about better experience with enhanced privacy and security. This is exactly what OAuth sets to achieve. With web services on the rise, people expect their services to work together in order to accomplish something new. Instead of using a single site for all their online needs, users use one site for their photos, another for videos, another for email, and so on. No one site can do everything better. In order to enable this kind of integration, sites need to access the user resources from other sites, and those are many times protected (private family photos, work documents, bank records)."

Adam Kalsey, summarizes it well:

"OAuth aims to standardize the way in which different consumer systems share data. The goal is to allow a person to give an application access to do some things on your accounts at other sites, but not everything. It’s role-based authorization for APIs."

OAuth is a big idea, but is it a "solution looking for a problem to solve"? I don't think so. The problem for end users today is real, i.e. authorizing one service to access your data by another service for use by the first service, securely and with control. For developers wanting to develop apps and services that create value through the use of customer data stored on other services, there is no standardized means set of protocols to lean on. Instead, developers need to waste time learning a new way for their app to be authorized to do so for each service provider, having to jump through the various specific means and idiosyncrasies of each service.

The current way is broken - too many means to the same end, for end-users, for developers leveraging service APIs and for the service providers themselves wanting to extend their services through web APIs.

OAuth is getting the attention from a number of people and services such as Six Apart and others ("Digg, Jaiku, Flickr, Ma.gnolia, Plaxo, Pownce, Twitter, and hopefully Google, Yahoo, and others soon to follow") have committed to run with it. This is good news, but we need to get the word out there and help make developers' lives easier. So, go listen to first OAuth podcast and evangelize OAuth!

Topics covered:

Background on Chris, Larry, and Eran
What problem is OAuth trying to solve?
What is the current identity landscape - what are the alternatives, and why is OAuth a better way for all?
How does OAuth work, who should use it?
What's the development experience like?
What's the end-user experience like?
What's the relationship between OAuth and OpenID?
Where is OAuth today?
What will it take for OAuth to succeed?
Who's backing OAuth - adopters?
