07.12. One-click Deployment
+0 Vote Up -0Vote Down

Today's topic is deployment. It's called one-click deployment for a reason: Developers are lazy.
It's hard to do less than clicking on one button, so that's our goal.

With the growing need for lower time-to-market and faster response to user feedback it is inevitable to not be limited by technical factors (there are enough other obstacles already). The focus lies on reproducible results.

So, what do we need? Actually, not much. Disregarding the tools and practices that build the foundation of agile software development, you only need a central build server. But you've already got that one covered, right?

If you don't, you should get one. It's a huge help to discover errors quickly and be alerted instantly. This usually leads to a shorter time frame until a fix is done. Tests are run continuously and new parts are

Test-driven SQL development

I'm having a lot of fun writing common_schema, an SQL project which includes views, tables and stored routines.

Background Knowledge


It appears this depiction of the Canadian political left and right originated as far as I can tell by johnnyslow [at] gmail [period] com around the end of the 2005. I recently heard the below of what I’m reposting on Charles Adler radio show.

I was so impressed by this analogy I had to post it for others that may have not read it yet.

Classic Version


The ant works hard in the withering heat all summer long, building his house and laying up supplies for the winter. The grasshopper thinks he’s a fool, and laughs and dances and plays the summer away.

Come winter, the ant is warm and well fed. The shivering grasshopper has no food or
shelter, so he dies out in the cold.

THE END

The Canadian Version
