Looking at Jabber recently caused me to see this prior discussion in a new light.\u00a0 With Google Talk<\/a>, one\u2019s gmail.com email-style address is one\u2019s identity.\u00a0 I just created a second address, one without a gmail.com account behind it.\u00a0 And Google Talk and GMail seem to be doing just fine.<\/p>\n

While the information in the form will be initially seeded with your remembered comment name, email, and URI (if available), the registration information is completely separate and can be changed independently.<\/li>\n

My goal is to keep this simple.\u00a0 If you are looking at a page, three mouse clicks and you can be subscribed (it may take more based on your OpenID provider).\u00a0 One subscription list per OpenID.\u00a0 You can subscribe to all comments, just the entries that you have commented on, or add subscriptions to any of the ten most recently posted or commented on entries.<\/p>\n
As an aside, this deceptively simple form has lots of combinations to deal with: new user vs returning user, GET vs POST, cookies available or not, unauthenticated user vs failed authentication vs fully authenticated user vs previously authenticated user whose authentication has timed out.\u00a0 If you find some combination that doesn\u2019t work as you would expect, let me know.<\/p>",

It certainly is a dramatic improvement.\u00a0 And it was fun to be a part of the process.\u00a0 But full and complete?<\/p>\n
From the format side, I\u2019d like to see support for a feature you see on the WordPress Codex<\/a>.\u00a0 Namely a checkbox that says \u201cThis is a minor edit\u201d.\u00a0 Such a feature could reduce the amount of times an entry show up your feed reader after somebody goes back to fix a few typos.<\/p>\n
On the protocol side, I\u2019d like to see support for foreign markup<\/a>.<\/p>\n
Internally, I\u2019d like to see a little code cleanup.\u00a0 Atom entries are produced in two places, and consumed in two places.\u00a0 It would be nice to consolidate this a bit.<\/p>",

The map/reduce jobs will typically be written in JavaScript.\u00a0 By that I mean what you get when you apt-get install spidermonkey-bin<\/a> and run from the command line, and not what you get whey you run within Firefox.\u00a0 If you like, other languages could be substituted, if a strong enough case could be made.<\/p>\n
The set of potential microformats is unbounded.\u00a0 I\u2019d like to be ready to handle microformats that haven\u2019t been invented yet.\u00a0 But to provide some specifics to this use case, lets consider hCalendar<\/a>.\u00a0 It contains dates and locations.<\/p>\n

Content Encoding Tests<\/h3>\nThis is real low hanging fruit.\u00a0 JSON can be a mildly verbose<\/a> text based format, and therefore is amenable to standard compression techniques.\u00a0 In the HTTP GET case, this can be implemented without affecting any existing clients.\u00a0 The way it works is that the user agent indicated, via an Accept-Encoding<\/a> header what types of compression techniques it supports, and the server sends back a Content-Encoding<\/a> header with its response indicating which compression method it chose.\u00a0 In the default case, neither sends such a header, and the data is sent back uncompressed.<\/p>\n
As an indication of how transparent and widespread this is, XMLHttpRequest<\/a> on Firefox handles this automatically, which means that the couch_tests.html<\/code> now run compressed.\u00a0 Yea!<\/p>\n
Neither the server support nor the unit tests for compression on PUT and POST are implemented yet.\u00a0 As this involves compression of the requests themselves, it is a bit presumptuous for clients to assume that the server supports the compression technique chosen, so this technique is less often used in the wild.\u00a0 Still, this should ultimately be implemented as there likely will be some clients that would trade off a bit of coupling for bandwidth savings.<\/p>\n
Content Negotiation Tests<\/h3>\nThis feature is of less value, but it takes virtually nothing to implement.<\/p>\n
HTTP, as a protocol, is not based on the presumption that clients and servers must be layered similarly in order to meaningfully interact.\u00a0 To the contrary, any given server should be able to interact with a wide range of user agents.<\/p>\n
A generic application, like a browser, may not understand a given data format.\u00a0 Firefox, for example, currently handles application/xml<\/code> automatically, but does not handle application/json<\/code>.\u00a0 For such an application, sending responses as text/plain<\/code> may help with debugging.<\/p>\nA CouchDB specific library<\/a> already \u201cknows\u201d what data format it is expecting, and needs no additional hints.\u00a0 For such applications, the Content-Type<\/a> may not matter much.<\/p>\n
A generic URI library may be able to provide additional value add if it knows the content type it is dealing with.\u00a0 For example, with JSON, it could pre-load the data.<\/p>\n
The way this is supposed to work is similar to the Accept-Encoding<\/code> header above: an Accept<\/a> header is sent indicating what content types are supported and preferred, and the server can use this information to adjust its response.<\/p>\n
Again, the sole purpose of such a feature is to enable serendipity.\u00a0 If/when a browser comes out that supports JSON to the same level that modern browsers support XML, Basura will be ready.\u00a0 Additionally, Basura specific libraries (ha!) could use this information as a sanity check of responses before attempting to JSON decode them.\u00a0 Yes, some mis-configured servers have been known to send back 200 OK<\/code> responses with associated text that contradicts this status.\u00a0 Checking the Content-Type<\/code> of the response doesn\u2019t absolutely guarantee anything, but it does tend to increase the amount of number of times that a library can produce a more meaningful error message.<\/p>\n
Conditional Processing Tests<\/h3>\nThis feature can potentially produce the biggest benefit, though it will require a bit of a change to the existing CouchDB interfaces.\u00a0 Hopefully it is early enough in the development that these changes can be considered.<\/p>\n
As with everything else HTTP related, it involves exposing a bit more metadata in HTTP headers.<\/p>\nFor starters, there is an ETag<\/a> which is a string that is guaranteed to change every time the resource does.\u00a0 CouchDB revision IDs are perfect for this.\u00a0 As an aside, clients are discouraged from making any assumptions about the values of ETags.\u00a0 For this reason, a case could be made for \u201clightly encoding\u201d (say, ROT13 or equivalent?) these values.\u00a0 On the other hand, exposing the revision IDs in this matter makes debugging a bit easier.<\/p>\n
Secondly, there is a Last-Modified<\/a> header that can be used for basically this same purpose.\u00a0 Given its granularity of a second, It is inferior to ETags but as some clients are happy enough with it, servers should support it.<\/p>\n

I can\u2019t help but wonder why Joel and others didn't make greater use of Dean Edward\u2019s IE7<\/a> at the time.\u00a0 Possible reasons:<\/p>\n
\nJoel and others hadn\u2019t heard of Dean\u2019s efforts at the time, for whatever reason.<\/li>\n
Browser incompatibility wasn\u2019t so much of an issue in 2004-2005.\u00a0 One way to look at this is that IE\u2019s dominance at the time was substantial enough that developers could get away with requiring IE and the situation has changed enough that this merits revisiting.<\/li>\n
Dean\u2019s efforts were in the wrong direction... people prefer the APIs as Microsoft implements them.<\/li>\n
Dean\u2019s efforts were incomplete, or performed poorly, or was otherwise inadequate.<\/li>\n
Dean\u2019s IE7 was an all or nothing proposition.\u00a0 It would modify the behavior of existing apps, which was unacceptable.<\/li>\n
Applications worked nearly enough without the download that enough people wouldn\u2019t make the effort, and the net result would be one additional platform to support.<\/li>\nDean\u2019s efforts, while interesting, didn\u2019t have enough corporate backing to justify a company to depend on it.<\/li>\n<\/ul>\n\nPossible solutions:<\/p>\n\nMicrosoft, Mozilla, and others work to eliminate their differences.\u00a0 Joel discounts this possibility, and given the progress at WHATWG<\/a> and the W3C<\/a>, it is hard to argue with Joel\u2019s assessment.\u00a0 Microsoft has to walk a fine line between throwing its weight around and not showing up, and at the moment they seem to be consistently erring towards the latter.\u00a0 Having a solid beta / tech preview would address this, but there is no indication that this is likely any time soon.<\/li>\n
Something like Silverlight<\/a> comes along (coupled with Moonlight<\/a>).\u00a0 Such a solution doesn\u2019t fix your CSS, it replaces many of the technologies that you are used to with new ones.\u00a0 There are no indications that such a solution will ever be deployed on an iPhone.\u00a0 Some have expressed concerns that once Silverlight gains enough tractions, the cooperation that Novell is currently seeing will dry up.<\/li>\n
Something like ScreamingMonkey<\/a> comes along and solves the JavaScript incompatibilities.\u00a0 I see no indication that this plans to address DOM incompatibilities or CSS incompatibilities, either of which alone can be worse than JavaScript incompatibilities.<\/li>\n<\/ul>\n\nOverall, I can\u2019t see anything in any of these solutions that is clearly better than reviving Dean\u2019s efforts, but I would be interested in hearing Joel\u2019s take on this.<\/p>",

It\u2019ll have all the same performance as native JavaScript with full access to the DOM in a consistent fashion, and it\u2019ll compile down to IE native and Firefox native portably and automatically.
