After reading most of the docs, am I correct in understanding that Stashboard is a front-end display of event statuses, which need to be manually set by the site/service (or perhaps updated programmatically by mashing it up with nagios or some such)? That is to say, Stashboard itself does not do any sort of monitoring or status checking on its own, yes?
-
Correct. Stashboard is simply a lightweight frontend display for your API/service status. It has a GUI and REST API that allow you to update status information. Using the API, one could wire Stashboard into Nagios or any other alerting system.
The Web Sockets API enables web applications to handle bidirectional communications with server-side process in a straightforward way. Developers have been using XMLHttpRequest ("XHR") for such purposes, but XHR makes developing web applications that communicate back and forth to the server unnecessarily complex. XHR is basically asynchronous HTTP, and because you need to use a tricky technique like long-hanging GET for sending data from the server to the browser, simple tasks rapidly become complex. As opposed to XMLHttpRequest, Web Sockets provide a real bidirectional communication channel in your browser. Once you get a Web Socket connection, you can send data from browser to server by calling a send() method, and receive data from server to browser by an onmessage event handler. A simple example is included below.

You can use Google Chrome and pywebsocket to start implementing Web Socket-enabled web applications now. We're more than happy to hear your feedback not only on our implementation, but also on API and/or protocol design. The protocol has not been completely locked down and is still in discussion in IETF, so we are especially grateful for any early adopter feedback.

Four announcements:
1) Firehose! No details yet (coming early 2010), but everyone will be getting full access to the data stream. This is pretty significant news.
2) New home for developers: new website launching within the next few weeks, including status dashboard, tutorials, and much more.
3) Anyone making OAuth requests to Twitter is soon getting an increased rate limit (10x) – about to launch API for browser-less apps, and starting Basic Auth decprecation in June 2010.
4) Twitter is hosting an official developer conference called Chirp
in San Francisco next year.

- The document's metadata
- The document's contents
- Both metadata and contents at once (using a MIME multipart request)
To update an existing document, first you retrieve the document you want to update, then you modify it as desired, and then you send a
PUTrequest to either theeditlink or theedit-medialink, depending on what is to be updated.You can update any of the following:
-
The new document contents, which form part of the MIME multipart request, must have a content-type for which conversion is supported--for instance, to update a Google Docs document with new content, it could have content-type
application/msword, or content-typetext/plain, but not content-typeapplication/vnd.ms-excel. When updating a Google Docs spreadsheet, however, content-typeapplication/vnd.ms-excelwould be appropriate. Content-types which are not supported by the document type being updated will result in an HTTP 400Bad Requestresponse. - 2 more annotation(s)...

Notes from Zuckerberg Keynote:
Facebook is growing 3% per week, which is 100,000 new users per day.
The fastest growing demographic is the 25 and up age group.
50% of registered users come back to the site every day.
Talking about how Facebook opened up registrations last year, and launched News Feed.
Facebook is generating more than 40 billion page views per month. That’s 50 pages per user every day.
6th most trafficked site in the U.S.
More page views than eBay. Says they are targeting Google next.
Applications: photos, groups, events. Plug into profiles. Use all the real connections people have
Their photos app is by far the number one photo site on the internet.
Events: similar story. 3x more ppeople invited to events thru facebook than evite.
Says these apps work so well because of the “social graph” - a network of connections through which people share information with friends.
The news feed feature in particular allows information to be pushed out through the social network to more people, faster than any time in history.
Deep intergation, significant freedom to monetize via ads and transactions.
