Sorry Google, Your Programming Test Is Not A Valid Measurement Of My Skills

Javalobby Syndicated Feed - Thu, 21-Aug-14 23:00
I’ve been talking with a very nice recruiter over at Google over the last couple weeks, and she has been so kind in keeping me updated about opportunities for evangelism at Google. This is the 3rd round of talks I've had with Google while being the API Evangelist, talks that historically go nowhere because of their programming test, which is a super silly aspect of their HR process. ...

Understanding JUnit's Runner architecture

Javalobby Syndicated Feed - Thu, 21-Aug-14 23:00
Some weeks ago I started creating a small JUnit Runner (Oleaster) that allows you to use the Jasmine way of writing unit tests in JUnit. I learned that creating custom JUnit Runners is actually quite simple. In this post I want to show you how JUnit Runners work internally and how you can use custom Runners to modify the test execution process of JUnit. Preview Text:  ...

Why We Need to Teach Kids to Code

Javalobby Syndicated Feed - Thu, 21-Aug-14 22:30
Obviously, don’t even get me started on the ridiculous skills gap we’ve got in technology and the fact that, in most schools, kids still aren’t being offered any options for learning programming. I can’t even understand it. So, when SheKnows asked me to write a couple of pieces on teaching kids to code, I jumped at the chance… Preview Text:  ...

The Need To Review The Agile Manifesto

Javalobby Syndicated Feed - Wed, 20-Aug-14 23:00
In 2001, when the Agile Manifesto was first published, technology in the workplace looked and felt very different to how it does today. High-speed Internet and data channels were still relatively new and communication channels more limited in variety. The sharing of information was nowhere near as easy as it is today. Nothing lived in the cloud and ‘drop box’ was something you did by...

Database Storage in Go with Structable

Javalobby Syndicated Feed - Wed, 20-Aug-14 23:00
I'm not a huge fan of ORMs. Don't get me wrong, I'm not about to start a campaign against them. I know that many people find them to be a great abstraction layer on their database. But I usually feel more productive with my query writing when I can just write SQL. Okay, not always. Writing plain old CRUD (Create, Read, Update, Delete) queries is a mindless chore equivalent to scrubbing the...

The argument for testing performance in production

Javalobby Syndicated Feed - Wed, 20-Aug-14 22:30
I encounter teams that do formal performance testing less frequently than in the past. For many teams, this is just the result of being spread too thin across QA and not having the resources to do performance testing well. However, in some more agile shops there’s an active argument against performance testing, especially load testing. Preview Text:  ...
