TDD (Test Driven Development) was introduced to me around 2006 with PHPUnit. As a naive, I couldn’t see the benefits, eg., I saw the pattern of code has been updated very often (growing organically) and frequent failing test. I was like, Why should I write unit test to test my own code? with the same data I used for manual testing? As they say I was seeing the forest for the trees. I failed to realize the failing test is actually the benefit of practicing TDD.
Remember my old post about the TOI - Epub project? Yesterday, I published the source on github. If anyone still interested, go ahead and take a look at the source. Kindly go through the Dev-Notes.txt, as it has all the urls and image path used to inspect their mpaper hiearchy.
I wrote a small plugin for sublime text to develop salesforce. I’m glad to share one of my idea to project execution.
Not many of my ideas are converted to a project, this one has seen its light last week. Though I haven’t completed all the UI and features of my original vision, it is better to have one working idea than nothing.
One of my long time wish to write a Chrome extension completed last week. It all started when my answer was down-voted at apple.stackexchange.com, the original answer was based on my experience sometime ago I was searching to migrate my links between my Instapaper accounts.
Recently I was in need of generating sample images for no. of products in my db. I really hate to create a copy of image for each products in my db.
I recently started using Git as my revision control tool. Impressed by the use of branching and merging, I create and merge a lot of branches. Our company use SVN and other peers were not aware/interested in Git. So I took the initiative to use svn-git. After months of progress I left with so many branches for features, svn, QA-release and quick-fix for released builds.
Finally decided to copy all my published userscripts.org codes here.
