Besides repeating the devops stories, we also need to seek diversity and make sure we keep adapting to situations.
What is a responsible way to use Grails with existing tables, and guarantee that it will not try to change those schema objects? If only Grails mapping had a simple way to turn off DDL on specific domains, but still retain the awesomeness of DRY methods like list(…), named queries, and even inserting/updating records through save(…).

All Logentries servers are configured for the UTC timezone. We use this as the default timezone for all internal data including customer’s logs. However, at the browser UI level we detect a user’s local timezone and present all dates in a more human friendly way, i.e. in the local time.
There’s no magic in how Deployit works, it uses existing parts of modern development environments, most notably CI servers.

There are times when work is, well ... a lot of work! The stress of important deadlines or goals can be overwhelming at times. Sometimes the "daily grind" can also have a sapping effect on overall productivity. How can we reverse this trend? By goofing off at work, of course!
Often a pull request cannot be merged online due to conflicts. If there's no conflict, it is easy for you to do merging, even from the web client, with one click.
Yesterday, I had a great time with the CincyPowerShell user group discussing security and delegation in PowerShell with PKI, code-signing certificates, PowerShell Remoting and PowerShell Web Access (new with Windows Server 2012! ).

It’s that time of year again where chefs (and sous-chefs!) come together to talk all-things Chef! This year’s ChefConf took place last week in San Francisco, and the crew of the Ship Show attended to experience it all first hand.
I was just checking the blog feed of an API that I monitor. It came up in my alert dashboard as a feed that wasn't pulling. I clicked on the link to test, and...
