I’ve been working for some time on a Perl module to parse XBRL, a complex XML based format for reporting financial information. The US SEC requires publicly traded firms to provide their financial reports in XBRL.

In the initial release, the module features a function to render the XBRL instance into a very basic HTML document. Because the XBRL standard is large and complex, support for its features will be added over subsequent releases.

I hope the new PC company gets off to a good start and they get to keep WebOS, but they will have to move forward without my efforts as an “app” developer.
One of the best business card tricks you can use is to turn your contact info into a bar code that can then be scanned into most smart phones.

By encoding the information on your business card in a QR Code, any one with a modern mobile smart phone, like Android, can then scan the information directly onto their phone. This blog post will walk you through creating the bar code and using the Android app to read the business card information. Continue reading
