JavaScript => Flash

So far the most portable web browser based rich UI technology I have seen is Adobe Flash. The coverage, consistency, and reliability they have provided, I have seen in other competing technologies.

http://www.macromedia.com/software/flash/about/

This is a good example of that... http://www.civilization.com/

(Well, I am a fan of this game :-D ).

Can this be extended to handle wider spectrum of problems. I was thinking about this because of some UI design discussions I am having with my colleges.

Today, I found an open source company who has a technology which make this a possibility. Basically they take a JavaScript description of a complex fancy GUI and compile that to a flash executable. Interesting....

SOA World Conference & Expo 2007 West - Day 2

Today I delivered my presentation. There were not many people in the conference, but I had a room full of people for my session :-). There are lot of interesting questions from the audience. After the session I received lot of good feedback for my ability to stay neutral without trying to market products from WSO2 during the presentation :-).

In the afternoon I had the TV interview with Jeremy Geelan. Jeremy Geelan is the SVP, Editorial & Events, SYS-CON Media.


BTW, after a long time I am driving in US. Would you believe, so far I haven't taken any wrong exits :-).

SOA World Conference & Expo 2007 West - Day 1

I am in the SOA World Conference San Fransisco now. WSO2 (Company I am working for) is a silver sponsor and they have a booth. There was some good traffic in the morning but it has kind of died now. Unfortunately there is another popular event, Oracle World happening out there in the same area. So people have to timeshare.

You can see me (right) and Subbu (left), our VP of sales and marketing in the picture.

I am delivering an architectural talk tomorrow on SOA Platforms. Soon after that I have a TV interview too. Hope every thing will go well.

Intellisense - vim => IDE cont.

Martin Stubenschrott has applied my patch to icomplete. He has made a version 0.5 release with some more fixes. However, he is not going to maintain it since he is working on another project which is very interesting too. => http://vimperator.mozdev.org/

With his kind offer I will try to maintain icomplete until OmniComplete come up with automatic tag update feature. So, please download it directly from the link => http://www.vim.org/scripts/script.php?script_id=1265

Intellisense - vim => IDE

On October 20th 2007, I blogged at bloglines about Developer Productivity and my interest about evaluating vim as an IDE for C/C++ programming.

http://www.bloglines.com/blog/SanjayaK?id=14

I manage to get intellisense working in vim for C/C++ source files by using already available vim scripts.

There are two vim scripts which can be used to enable intellisense for C/C++ code in vim.

icomplete - http://www.vim.org/scripts/script.php?script_id=1265
OmniCppComplete - http://www.vim.org/scripts/script.php?script_id=1520

OmniCppComplete is a set of vim script and has a good help. icomplete make use of a program and it doesn't has a good help. Also the latest update is in April 2006. However, it has the capability to automatically generate the tag file based on included header files. Therefore, I prefer icomplete over OmniCppComplete but propose some changes to make it more usable. I have mailed these changes to the author. Hopefully he will make them available to everyone soon.

Installation Steps
==========
* Download icomplete from http://www.vim.org/scripts/script.php?script_id=1265
* Follow the instructions and get it installed
* Replaced /etc/vim/plugin/icomplete.vim and /etc/vim/autoload/cppcomlete.vim with below given files
