Tonight, Microsoft has publicly launched Photosynth, its long awaited Live Labs product that allows you to stitch your photos together to create a detailed 3D environment.  While most of the computation is done on your desktop, the images are uploaded to Microsoft's servers and Microsoft is giving all Photosynth users a total of 20GB of storage for their collections. The rendering and browsing is done with the help of Seadragon, another Live Labs product.

Windows Only

When Microsoft first publicly showed a demo of Photosynth in 2006, it almost looked too good to be true. Now, getting started with it couldn't be easier - as long as you have a Windows machine - there is no Mac version available yet. You first have to install both a browser plug-in and a desktop application (all done through just one installer). The installation was as standard as Windows installations get and finished in less than a minute. We tested the plugin in both Firefox 3 and Internet Explorer 7 without any problems.

One interesting aspect of the uploader is that you can choose a license for your creation. You can either choose a Creative Commons license, put the pictures in public domain, or mark it as 'All Rights Reserved.'

Desktop App

The desktop application does most of the heavy lifting for creating the 'synths' and seemed to make good use of all available cores. You only have to pick your photos, give your collection and name and click 'Synth.' After it has finished, it will create a score telling you how 'synthy' your photo collection was. Obviously, your photos need to have common areas for Photosynth to be able to stitch them together. While Photosynth does a great job making these connections, it can't work magic and our first attempts with relatively unconnected images were futile.

The more pictures you have, the longer the process of creating your synths takes, of course, and depending on your connection, the upload to Microsoft's servers can also take quite a while. In the end, though, your patience will be greatly rewarded.

Online Viewer

The online viewer is quite intuitive and allows you to zoom in and out, move around the picture and also go through the pictures in a 3D slide show mode. One nice feature is that you can also go full screen, which is really the best way to showcase your photos.

You can also embed a copy of your synth on any website and email a link to your friends.

The animation in Photosynth is astonishingly smooth and our screenshots really can't do it justice. If you haven't seen it yet, you should watch Microsoft's demo of Photosynth at TED2007, which will give you a good impression of what the final product looks like.

Different Way of Shooting

It really takes a different approach to shooting pictures to make the most out of Photosynth. If you often stitch together photos, you are probably already used to this, but Photosynth also gives you more freedom, as you can zoom in and out, or walk around an object and still have Photosynth recognize the common areas.

In our tests, Photosynth performed flawlessly, but we would recommend that you have a set of at least 10 to 20 photos to create an interesting 'synth' and the more photos you have, the more interesting it will be.

Caveats

A couple of caveats:

• All synths are public - there are no privacy controls!
• Photosynth only runs on Vista and XP so far.

Verdict

Even though we only had a short time to test Photosynth, it has already changed the way we think about taking pictures. Suddenly, you can do so much more with your photos. But besides the cool factor, we can also see a lot of other interesting applications for Photosynth. A realtor, for example, could use it to create a more immersive virtual tour of a house.

If you already have Photosynth installed already, you can see a 3D view of Venice below - otherwise, clicking on the image will take you directly to the installer.

In this post we review 10 promising developer platforms for the Web. We're not talking about the obvious ones either, like Facebook, iPhone, OpenSocial or even Twitter. Those have been covered extensively already. The list below features some of our favorite 'lesser known' web developer platforms. There are bound to be other excellent developer platforms not noted below, so as always please use the comments here to point out your own favorites.

We've written a lot of times about developer platforms for the Web and we've reviewed a fair number of them. A web platform at its simplest is an API, allowing external developers to build on top of your web app or product. As we explained in our post APIs and Developer Platforms: A Discussion on the Pros and Cons, "offering an API is a great way to make developer friends and developing for a large Platform has the potential to bring your work to a huge audience."

Note: the content in this post has been written collectively by members of the RWW team. Also the list below is in no particular order.

1. Imeem Developer Platform: Music

Major social networking site Imeem launched a developer platform in March that will enable read/write access to user information and more. Imeem is a site where users can upload music, create and listen to any uploads and blog about music all for free. Imeem pays internet radio-style licensing fees for each time a copyrighted song is played.

The new platform is a Flex and ActionScript API that will let developers create customized music players, access activity data and build things like recommendation engines, smart playlists and music games.

2. YouTube Platform: Online Video

The video uploading platform announced by YouTube in March may not have been what many pundits expected but it could mark a major turning point for both YouTube and thousands of other sites around the web.

By allowing website owners to combine an on-site video publishing option for their users with the huge number of people looking to discover new content on YouTube, the platform will create a mutually beneficial feedback loop that will breathe new life into both YouTube and the web at large. It's also got potential to show up all the other big platform plays we've seen to date.

3. Fire Eagle: Yahoo's Location Platform

Earlier this month Yahoo announced that the closed beta period for its location platform Fire Eagle had ended and that the service was now open for everybody.. Since then, a number of high-profile services, including Brightkite, Movable Type, Dopplr, and Pownce have implemented Fire Eagle through the numerous APIs Yahoo provides for accessing the service.

As we wrote about Fire Eagle when the beta was first announced, it offers API kits in five different programming languages, it's got user authorization protocols already available for web, desktop and mobile apps and it's using the open standards community built oAuth to facilitate faster, more secure mashups. This ain't no cry-baby do it my way or I'm taking my ball and going home framework like the Facebook platform. This is leveraging universal open standards.

Note: also see our coverage of the Yahoo! Internet Location Platform, a collection of in-depth geo-location based APIs.

4. Mozilla Weave: Web Platform for User Data

Mozilla recently announced Weave, a new web platform that will store users' browser metadata in a cloud environment for access anywhere. Weave is a "framework for services integration" that will, according to Mozilla, "focus on finding ways to enhance the Firefox user experience, increase user control over personal information, and provide new opportunities for developers to build innovative online experiences."

The basic idea is that browser metadata (things stored in your Firefox profile like bookmarks, history, RSS feeds, usernames and passwords, etc.) is pushed into the cloud and stored on Mozilla's servers. The data is available to users from wherever they get online and users can share information with friends, family, or third parties while retaining control over how, when, and if the info is shared.

5. Live Mesh: Microsoft's Multi-device Platform

The new Live Mesh service launched in April as an invite only "technology preview". It is Microsoft's attempt to tie all of our data together. Live Mesh synchronizes data across multiple devices (currently just Windows computers, but theoretically it will extend to mobile and other devices in the future) as well as to a web desktop that exists in the cloud. It can sync data across devices used by a single users, as well as create shared spaces for multiple users. On the surface, Mesh is a lot like competing file sync services such as Dropbox, SugarSync (which we covered in January), and even Microsoft's own FolderShare product. But what sets Live Mesh apart is its platform approach.

Essentially, Live Mesh is a collection of feeds (which can be expressed as ATOM, JSON, FeedSync, RSS, WB-XML, or POX). Every piece of data entered into a user's Mesh -- be it a file, a folder, a message, a user permission, or a new device -- is rendered as a piece of information in a feed. The feeds are then synced with other devices that are part of that Mesh following rules for how to sync each particular piece of information (i.e., File A may sync with Users 1, 2, and 3, while File B may only be told to sync with Users 1 and 2).

6. Hakia's Semantic API

Semantic search engine Hakia announced in June a set of APIs that opens up their natural language processing and search platform to developers. Hakia's Syndication Web Services really comes in two parts: search queries, which allow developers to add web search functionality leveraging Hakia's five billion page index, and XML feed calls, which give developers access to Hakia's underlying natural language processing technology. The latter of the two is clearly the more compelling of the offerings.

What is more interesting are the XML feed calls that Hakia is offering that give access to their underlying NLP engine. [disclosure: hakia has been a RWW sponsor]

7. Iceberg: Everyone Can Program

There was a time when only technically-savvy people knew how to create content and publish it to the internet, but the rise of easy-to-use blogging and CMS systems changed that. Today, everyone can be a publisher. Now, Iceberg wants to bring that same democratization to programming. In fact, that's their vision for Web 3.0 - the web where everyone is a programmer.

Build an App in 3 Minutes

In June Iceberg launched publicly. Although the focus is on business applications, like CRM or PM tools, you can interface with anything that offers up a web service. For enterprise environments, instead of using Iceberg as a service, I.T. departments can download and use Iceberg offline, behind the firewall, to work with their in-house servers, like Windows SQL server for example.

8. Cascada Mobile: Anyone Can Build a Mobile App

In July Cascada Mobile launched a platform called Cascada Breeze, allowing anyone to take their idea from thought to app in about fifteen minutes. Well, maybe not anyone - the apps are built using HTML, so you would have to have some rudimentary web programming knowledge to use their platform. Still, you have to admit, that's a lot easier than using a professional development platform.

With Breeze, you can build, test, and distribute mobile J2ME apps that run on hundreds and handsets. And these are "real" apps, too - fully integrated mobile applications with their own icon, not just mobile widgets.

9. Android: Google's Open Mobile Phone Platform

We said we wouldn't discuss iPhone, but we can't help mentioning Android - because of its potential to really open up the up-till-now closed mobile phone platform ecosystem. Earlier this week we reported that the HTC Dream, the first handset to run Android (aka "the Google Phone") has been approved by the FCC. In the documents provided, it appears that we have now a release date for this highly anticipated phone: November 10th, 2008.

Google has been encouraging developers to create applications for Android and rewarding them for doing so with cold, hard cash with the Android Developer Challenge. (See our previous coverage here). This has led to numerous third-party applications ready to flood the market when the phone goes to launch, regardless as to which developers win the big prizes (Pictured: Teradesk App). According to PCWorld, Google Developer Advocate Jason Chen told the Android breakout session at May's Google I/O event that developers won't need to get Android applications certified by anyone nor will there be any hidden APIs accessible only to handset makers or mobile operators. Even the phone's homescreen and widgets will be customizable - that's a much different take than the locked-down iPhone - and one that caters to users who like to make their phones their own.

10. Meebo: Web Instant Messaging

Unlike most other platforms in the news these days, the Meebo Platform is a closed one. As at December more than 300 companies had registered to build applications but only 39 had been accepted into the program. Most are multiperson gaming apps, the rest video and voice chat apps. Companies chosen to participate in the Platform work closely with Meebo to assure high-quality integration of their applications, the company says.

The Meebo Platform is the third step in the vision for the company, after building a basic web IM service and then integrating that service into other sites through tools like MeeboMe and MeeboRooms.

We get excited around here whenever a new application offers an Application Programming Interface (API) for 3rd parties to develop against. Oh, the possibilities! Sometimes, though, it just doesn't pan out and our dreams are dashed against the craggy rocks of reality. Mashups are hard and just because you've got some cool data and good hooks for developers to pull from doesn't mean anyone's going to build anything worth using on your API.

Such appears to have been the fate of news platform Daylife, a company funded by some of the biggest names in tech and new media. Daylife recently held a "developer challenge" giving cash prizes to the people who built the best mashups with their API. Unfortunately, the entries they got were awful.

Mashups Mashups Mashups

We learned about the Daylife contest today on Programmable Web, the leading blog and database about public APIs and mashups. PW must have felt obligated to be polite and just report on the contest, albeit weeks after the winners were announced.

We were really excited to learn about the contest - Daylife is a company with some good technology, offering news content with some structure to it. What could make more interesting fodder for mashups than structured news data? It turns out almost anything could, if you judge from what came out of it.

If you can't see the video above where we look at the mashup contest entrants, here's a Flash version.

To take a tour of all the applications discussed in the video, you can visit this link.

There Is Still Potential Here

The examples that came out of the contest are all relatively dismal, with the exception of the touchscreen news reading interface. Over on Programmable Web's page about mashups built on the Daylife API though, we found one very cool one. TreeHugger's GRNDX tracks media mentions of a number of words related to the environment. (No one cares about the environment this week, apparently, the Olympics are all anyone cares about.)

That's pretty awesome - even if Treehugger calls it more fun than scientific. Fair enough, but let's see more apps like this instead of the wacky stuff that dominated the Daylife contest.

News has emerged that the Chinese government has detained at least five bloggers from the United States for reporting on protests in favor of Tibetan independence. Included among the detained was the widely admired founder of the video blog series Alive in Baghdad, Brian Conley.

The detentions follow a wave of arrests of Chinese dissidents leading up to the Olympics. The US government pledged as the games began to engage the Chinese government concerning human rights - we wonder what those conversations look like now that China has detained journalists consistently critical of US policy as well.

Blogging is Powerful

New online media have opened the doors to people publishing on budgets that would never have supported journalistic efforts in the past. That new generation of publishers has a greater freedom to take risks because they aren't as beholden to the interests of sponsors. That's one way to describe the political impact on journalism of blogging - another way might be that these new media have opened up publishing to activists with less interest in objectivity than traditional journalists have aimed for.

Either way, the impact of blogging and video blogging on the world at large is widely recognized and it's no surprise that the authoritarian Chinese government is taking steps to protect itself. We condemn the detention of any journalists, whether they strive for objectivity or tell stories from a particular perspective.

According to extensive coverage on BoingBoing, the following US journalists and/or activists are all currently missing:
- James Powderly
- Brian Conley
- Jeffrey Rae
- Jeff Goldin
- Michael Liss
- Tom Grant

We're working on creating a widget displaying video, information and a button to call US Congressional representatives but for now we'll leave you with the following video published by Conley in China last week. Update: Ribbit.com doesn't want to give us an account promptly, so we'll just say - if you want to call the US Congressional Foreign Affairs Committee to register your concern about the 5 people above, they are at +1 202 225 5021 and they are waiting for you. We just called them a few minutes ago.

At Intel's Developer Forum, Yahoo today announced an initiative to bring the Internet to your TV set through what it has dubbed the 'Widget Channel.' While many a company has tried to bring the Internet to the living room (and mostly failed in the process), Yahoo is taking a slightly different approach by not trying to bring a full browser experience to the TV, but by creating a platform for widget developers.

The Widget Channel will allow developers to create widgets that will display on TV screens in JavaScript, XML, HTML and Flash. Yahoo will curate a directory of widgets and has currently signed up Blockbuster, CBS, CinemaNow, Disney-ABC, eBay, Joost, MTV, Samsung, Toshiba, and, interestingly, Twitter, which Yahoo demoed during the announcement at the IDF.

Comcast is also joining in the effort and will start testing the Widget Channel framework in the first half of 2009.

Challenges

By just focusing mostly on relatively simple widgets for now, Yahoo is at least partly sidestepping one of the major issues with bringing the Internet onto a TV set: navigation. As long as you only want to bring up some widgets on your screen, a simple remote control will do. However, as a typical usage scenario, Yahoo expects its users to want to browse to a friend's Flickr photos while watching a TV show - at that point, trying to find a set of photos on Flickr might just a bit more than your standard remote can handle.

Yahoo might be planting a Trojan horse in every living room here by creating a demand for Internet enabled TVs - but the real problems for interactive TV have never really been technical. Most users simply aren't interested in interacting with their TVs beyond flipping channels. The Widget Channel might just be simple enough for more folks to start using it and it might precipitate a cultural shift in how we look at our TVs, but so far, every other similar initiative has failed because of a lack of demand.

If you would like to see the slides that accompanied the IDF presentation, you can find them here (PDF). We will also provide a link to the video of the presentation once it becomes available.
