TinyBuddy IM v3 released

This version of TinyBuddy IM converts the code to iUI for look and feel, and to Dojo 0.9.0beta for the JS part. As part of the conversion, the following features
have not been implemented yet, but I am planning to get to them in a coming release:

* No Custom Away messages
* Cannot show buddies by group (only alphabetic listing).
* Typing events received from buddies is not implemented.

If you would prefer to use those features, you can keep using v2 of the UI at:
http://tybyim.com/v2/

However, v3 is really nice since:
* You can use the normal one finger physics-based scrolling for the buddy list and IMs.
* It looks way nicer with iUI.

The size results for the HTML/JS/CSS: 39KB gzipped (2.6/33.6/2.5).

The images I use probably come in around 10KB in total, but not all are loaded up front.

For the next release, I'm looking at the following:

* Still pursuing open sourcing the code.
* Implement custom away message.
* Implement buddy typing events.
* Provide SSL option for all IM/buddy list calls.
* Allow sorting buddies by group and/or not showing the buddies in the Recent Buddies group.

Possible features for TinyBuddy IM v3

Here are some things I'm looking at for future TinyBuddy IM releases. I hope that most of these will make a v3 release, but we'll see how it goes:

* Convert the UI to follow iPhone standards as demonstrated by iUI. I'm not sure yet if I can use iUI straight out of the box, but I'll be looking at it, if anything for inspiration (The main issue could be licensing/legal stuff -- if I want to open source my code, I need to have some very clear code copyright/licensing history. More info below).

* Try to open source the TinyBuddy code.

* Offer an https option, so that all IM traffic is encrypted.
 
*Add a preference on the sign-in screen to specify whether to use the alphabetic buddy listing or use the AIM groups for buddies.

Feel free to offer other suggestions. Keep in mind I want to stay true to these principles:

* Stick with pure HTML/CSS/JavaScript for the interface.

* Continue to rely on the AIM servers for logging in the user, so the code does not see the user's password.

* Make it possible to open source the code, perferably to the same standards that Dojo uses for its code (clear tracking of who added what to the codebase, offer the option of either Academic Free License or the BSD license on the code).

TinyBuddy IM: Release (v2)

Today I did a small update to TinyBuddy IM (about). I'm calling it the v2 release. As I do a release, no matter how small, I'll just up the v number.

The biggest change is in response to Trevor's request for grouping. I had support for showing buddies by group before I had the iChat-like alphabetical buddy listing, but I had to work out an application switch and update the styles a little bit.

The upshot: if you put a bl=group on the TinyBuddy IM URL, the buddy list will show buddies in groups:

http://tybyim.com/?bl=group

Groups can be collapsed and expanded. Leave off the bl=group to get the normal alphabetical buddy listing.

Other things that were updated:

* If you are typing a message and a new IM comes in from another buddy, there will be a notification in the current IM pane.

* A Send button in the IM pane. It seemed like a couple people didn't realize that the bottom text box was for typing and sending IMs. I hope having the explicit button helps. It also makes makes the UI mostly usable (if a bit small) on a Nintendo Wii. :)

* Some small style changes.

I also think that .mac accounts should work since they use AIM behind the scenes, but I'm not totally sure on that. If someone with a .mac account can give it a try and post the results, I would appreciate it.

And as I mentioned in a previous post, you can register your email address to use as an AIM ID (to log into TinyBuddy IM, and to use as a valid OpenID).

On the release: I tried getting the scrollTo thing to work as Kai suggested, but I think the Dojo AccordionContainer is doing some weird sizingthings that makes the window.scrollTo calls not "hide" the address bar in iPhone Safari once I show the buddy list. So more investigation needed there.

Why an AOL Journal?

I'm going to use an AOL Journal for now to log my TinyBuddy IM notes. I looked at using a Blogger blog (since I use one for my other blog), but there were some specific iPhone-related features for going with the AOL Journal.

My biggest problem with Blogger, is the mobile blogging. Right now, it only accepts email addresses from one of the cell phone networks. Since mail on the iPhone is just regular mail it does not work. Blogger has an email-to-post option, but it does not accept pictures.

An AOL Journal allows email-to-post with pictures, so it is a great way to get pictures off the iPhone and up somewhere. I can also use IM (TinyBuddy IM!) to post blog entries. I IM the AOLJournals bot to do it. It's like blog posting on the command line.

My biggest negative for the AOL Journal: lack of anonymous comment support. So, if you want to leave an anonymous comment, post an comment to this blog entry on my other blog: [link removed Oct. 4 2007].

(Update Oct. 4, 2007: I have rethought the value of anonymous comment support. The vast majority of posts were either spam or not on-topic, so I am removing the entry on the other blog that allowed anonymous posts. I now think it is good that the AOL Journal does not support anonymous comments. There can still be issues with authenticated comments, but anonymous comments are worse.)

However, there are some neat features about using your AIM name (or even your email address) to leave a comment on this site. You will have to register the name you want or use an existing email address, but after you do that, you get some neat capabilities:
  • You can comment on this blog
  • Use the name (or email address) your register to sign in to AIM (and TinyBuddy IM)
  • The registered name (or email address) is now a valid OpenID
The really neat thing about this is that you can register your email address as a valid AIM-recognized identifier. Just about any email address. If you register whatever@yahoo.com, you can now use that to log into AIM/TinyBuddy IM (you can't see the Yahoo Messenger people though, this is just an identifier that is used on the AIM network).

Same thing with the OpenID support -- if you go to other web sites that accept OpenID, you can plug in this URL to sign in (using the whatever@yahoo.com example):

http://openid.aol.com/whatever@yahoo.com

Neat, but weird.

Note: if you do use your email address as an AIM identifier, and you leave a comment on this blog, your email address may appear in the comment. I'm not sure if this opens it for collection by spam bots, but be aware that it may be visible on the page.

In a future post, I'll explain how to set up your iPhone so you can post to an AOL Journal via email, including sending a picture.

TinyBuddy IM: Instant Messaging for iPhone (v1)

(This is a repost from my other blog, but putting the content here for completeness)

Have an iPhone, but wish you could IM your buddies? Now you can, with TinyBuddy IM. It is an AIM® Enabled web-based IM tool. It works by using the Web AIM API, OpenAuth and Dojo.

The nice thing about this solution: you do not send your AIM password to me -- you are redirected to AOL's OpenAuth servers for authentication. My JavaScript only sees an auth token. Furthermore, my web page has to get your explicit consent before accessing your buddy list data and before sending the first IM or presence change.

So the price of this added security is pop-up windows. A new window will be popped so you can authenticate with the OpenAuth servers, and also when giving consent to the application to access your buddy list and IM. For the consent prompts, you can choose "Grant Always" to avoid them on subsequent logins. I think the pop-ups are worth the added security, and at least in iPhone's Safari, window popping looks neat. Unfortunately, the OpenAuth Sign In and Consent pages are made for larger windows, so you will have to double-tap zoom to read them.

Another neat feature of this web application: it is pure JavaScript, HTML and CSS. No server-side languages needed. Dojo really made it easy to do this. I used Dojo 0.4.3 because I want to reuse this code for some other projects that are on 0.4.3, but if/when I get enough time, I would like to port it over to the 0.9 code.

So give it a whirl if you like. I'm sure the code it not bulletproof, and I've noticed enough weirdness with iPhone's Safari to guarantee that I will not be able to give comprehensive support. Also, even though I'm an AOL employee, AOL does not endorse this project or have anything to do with it (but thanks to my co-workers for ideas and early testing, all done of their own accord).

Also, I'm using an OpenAuth dev key, so if there is too much usage you might see some rate limit errors, but we'll see how it goes.

Some other interesting tidbits:

  • The Web AIM API is a Comet API. It uses long polling to work cross-domain in the browser. I'm using more of a short poll with pauses between the polls to hopefully smooth out network hiccups on the phone.
  • Don't like the CSS? You can make your own and tell the app to use it instead. Go to the test launcher page to specify the path to your CSS. Click the Launch button, then copy launch URL. Use that URL when you want to use the application. This feature is not allowed for IE browsers given its security problems with CSS "expressions".
  • I'm serving the code gzipped. The HTML, CSS and JavaScript combined come to about 90 KB. So it is tolerable on the EDGE network.
  • Use the iPhone two finger scroll to scroll the buddy list and IM conversations.
  • Typing IMs should be optimally sized for use with the virtual keyboard. Just type in the text box at the bottom of the IM window and press "Go" on the keyboard.
  • I'm using Dojo Accordions for the IMs and buddy list. I like the use of space with that model and that I can show you incoming IM text if that IM AccordionPane is in the closed position.
  • onbeforeunload does not seem to fire for iPhone Safari. That makes it hard to log out correctly, so to clear your OpenAuth cookies, be sure to use the Available, Sign Out menu item.
To use TinyBuddy IM, just type http://tybyim.com in the iPhone Safari browser. You can try it in other browsers, but it looks best in the iPhone Safari.
