Before considering building my own, I’m looking for php/mysql implentations of Yahoo Answers. So far, the best examples is Askeet built by the symfony Web PHP Framework. I’m going to give it a try, but always looking for alternatives.

Yahoo focuses on the full capabilities of the iPhone’s Safari browser including browser cache and transfer speeds. It’s an interesting read, for example:

The iPhone has an amazing UI, but it is limited by the small cache size and slow network speed. Downloading large components over the air through the EDGE network is slower compared to DSL. According to published reports, the typical data download speed varies from 82 kbps to 150 kbps. Though the WiFi network speed is usually more acceptable, it’s better to give users the choice in which experience they’d prefer.

Niall Kennedy has a nice summary:

Web applications built for the iPhone’s Safari browser need to specifically target web performance these small devices and special cache rules. Desktop browser best practices such as zipped components and combined files for CSS and JavaScript may be too bloated for the Safari mobile browser. A few tips:

• Limit cacheable components to a decompressed size of 25 KB or less
• Limit yourself to 19 or less cached components
• Minify CSS and JavaScript for slimmer file weights.
• Use CSS sprites to combine multiple small images into a shared image under 25 KB

Also, don’t assume those viewing your iPhone / iTouch site are using wifi. Remember, iPhones will probably be using slower EDGE.

Scott Klarr has cheat sheets for Javascript, jQuery, Scriptaculous, MooTools, Prototype, Microsoft Ajax Library, Yahoo YUI, and Symfony. Quite a list, probably should grab these or bookmark.

I never realized how much flash resources and code Yahoo offers. A borrowed the description from Coding Cowboys on what they’ve just come out with, but i’m wondering what happens if and when Microsoft buys Yahoo? Will this all go away or change into Silverlight?

Yahoo! Developer Network releases ASTRA, the ActionScript Toolkit for Rich Applications. A collection of Flash and Flex components, code libraries, toolkits and utilties developed by Yahoo! for ActionScript developers.

ASTRA Flash components comes with the Tree, Menu, TabBar, AutoComplete, Charts, AlertManager, AudioPlayback, and MenuBar components for Flash CS3.

ASTRA Flex components include AutoCompleteManager, ColorPlaneAndSliderPicker, ColorSliderPicker, DropDownColorPicker, IPv4AddressInput, TimeInput, and TimeStepper components for Flex.

Microsoft & Yahoo - This Kara Swisher article plus this winners/losers piece from Tristan Louis are the best articles so far. I’m hoping it doesn’t happen personally.

Chris Charlton has put together dreamweaver extensions that offer support for jQuery 1.2 and Prototype 1.6 development. Looks like Yahoo YUI and MooTools might be future options if there’s enough demand.

Yahoo UI libraries are great, but sometimes I wished I could improve performance by only loading the ones I needed. Bookmarking a possible way to do this, so I can review later. Found about this YUI technique here.

Saw this on mashable today - Yahoo Shortcuts can suggest and add Maps, Finance, ok-to-use images and more to your blog posts. Not sure if this helps or adds content spam, so i’m bookmarking to check out later.

I have used Yahoo’s UI Toolkit, and it’s very good. New version released with css selector, charts, profiler, script/CSS Get, and JSON Support.

Cloaked or disguised agents can mimic Google, MSN, Yahoo, and Ask… so here’s a way to verify if they are actually who they say they are. Reverse and forward DNS lookup warning.
