Using your Gmail account for sending automated SMTP emails

Blogging just tad short of a full year, oh well...

Anyways, I today came back to the admin section of my website after a loooong time and noticed automated email alerts from the site (for example comment notification emails) have been failing for sometime. The site uses a Google Apps account to dispatch emails, and I din't thought anything had changed on the account for smtp email delivery from the site to fail.

I tried sending a test email and got this error in my site logs (email addresses changed for obvious reasons):

Web 2.0: 

We have been using Crystal Reports for our Travel CRM with good results for a few years now. We use a completely custom ExtJs based experience for Report viewing which includes a custom user interface for entering report parameters (see screenshot below for an example) and a custom toolbar for managing report navigation and exporting etc (I had blogged about the toolbar earlier here).

Despite deeply wanting  to keep writing, I hardly get a chance to do so these days. But so much for the ranting, time to get down to business now.

Hello World :)

It's been so long since I last blogged, it essentially feels to be blogging like first time. A lot has happened all this time, and I hope I would be able to share some of my learnings more frequently going forward.

Debugging issues with payment gateway integrations in development environments

Today's the end of a financial year (atleast here in India), so I thought I should write a post related to this sector. Now considering that I have a hardcore technical background, it shouldn't come as a surprise if the post rather gets techno-financial. So here's how it goes.

If you have ever worked on an eCommerce product or platform and have written custom code to provide integration with any Payment Gateway, you would know its a pain to write code to integrate with a Payment Gateway, and subsequently having to modify, adapt or debug it after it has been pushed to production.
