It’s hard to believe, but just barely a year ago I joined Jeff Haynie and crew to work full time at Appcelerator. My original goal was to write Eclipse based development tools for the javascript platform Appcelerator (now Entourage). Obviously things have changed a lot since then, with Titanium taking the company in a whole new direction, and my position now is perhaps a polar opposite of the thing I originally signed on to do. In any case, I thought it would be good to give a brief history of Titanium from my perspective.

After about a month of prototype tools (September-ish), Jeff and Nolan introduced me to a vision they had for developing desktop applications. The idea was a bit rough in the beginning, but it easily caught my imagination, and I grew very enthusiastic about the project. It was soon decided that I should shift to quickly coding an OSX based WebView wrapper, to get a feel for the effort needed to develop an early prototype/preview release. As it turns out, with only a few weeks of work, I was able to get a standalone WebView, Google Gears, some additional filesystem APIs, and a command line SDK worked out. This was the very first working version of Titanium, and it was the basis for the early work done for OSX in Titanium PR1. After prototyping OSX, I moved on to Windows to do a chrome-based wrapper, and Jeff and I teamed up to spec out the initial PR1 API, SDK, and other aspects of the platform.

Within literally 6 weeks, we had pushed PR1 out the door! It was December now, and at this time in Titanium’s development, things were moving so fast that neither Jeff or I got any kind of respectable sleep. Four AM and later were (and to some extent still are, as you see from this post) perfectly normal unplugging hours. As soon as we got PR1 out the door, we decided to drop Gears from the stack, and do a complete rewrite of the internal architecture. With Jeff’s lead, and our newest member, Martin Robinson a GTK and Linux God, we architected a modular microkernel and binding layer that freed us from the limitations of one platform or language. PR2, and all releases after it would use this architecture to deliver seamless integration of Python, Ruby, and Javascript with WebKit and the DOM. The binding layer also allowed us to bind our API directly into any language we support. Not only had we become a desktop platform for Javascript developers, but we were starting to address long standing limitations of Ruby and Python: A truly cross platform desktop framework, that lets you reuse the web technologies you already know. PR2 also included a major reworking of the Windows platform code, as we switched away from Chrome/V8 because of it’s slight behavioral inconsistencies with official WebKit. We were able to utilize the great work done by Brent Fulgham to realize a native redistributable WebKit for Windows using Cairo and cURL.

Around the time of PR3, we hired 2 more kickass developers: Dallas based Don Thorp, and Mac guru Blain Hamon. The next part of the Titanium vision involved the same basic ideas, but applied them to the disparate mobile landscape. It was natural then, since our technology was so young and cutting edge, to adopt platforms with our tried and true friend: Webkit. Quickly ramping up, Don and Blain put out an amazing product for iPhone and Android in just 2 months, just in time for Beta. At this point, we were ready to tell the world about our mobile aspirations, and to declare a public launch for the newly expanded Titanium platform.

Since then, we’ve made several minor and one major mobile release that includes native controls and views, and other niceties. A new version of desktop and mobile should be landing soon, and this should hopefully be the last release before our 1.0 production release coming soon. Stay tuned, I’m sure the next few years will be just as exciting, if not even more so than the one that’s passed.viagra patent levitra Viagra Price Comparison viagra anxiety;

Here’s some completely subjective numbers comparing Unladen Swallow 2009Q2 to the reference C implementation of Python (CPython). No discernable difference in a clean build, and CPython is a good bit faster on a simple update build (i.e. just file copies):

CPython, full clean build:
real    4m39.058s
user    5m55.781s
sys     1m17.358s

Unladen Swallow, full clean build:
real    4m28.640s
user    5m58.416s
sys     1m13.523s

CPython, updated build:
real    0m8.421s
user    0m5.554s
sys     0m1.115s

Unladen swallow, updated build:
real    0m11.049s
user    0m7.709s
sys     0m1.136s

Most of our build is filesystem / disk impaired, so these numbers probably don’t do Google’s latest build any justice, but it was something fun to try while debugging the new Titanium Process APIviagra anxiety; Viagra Store In Canada taking viagra woman
