Self-Taught IT?

I love the premise of this article: Just because you are a Self-Taught Developer/IT Guy doesn’t make you any less authentic in your field than someone with a BS or an MS.

Planning vs. Acting is procrastination.  Just go after it.

With the high cost and low quality of College courses these days, it has surpassed the threshold of not being with the value it once offered.


Java 8 Optional

My shop is considering development paths and frameworks.

One Framework path I am evaluating is a homegrown library, small and specific in nature, built on top of Google Guava.

Here is a quick GitHub writeup explaining the issue around null, and how the Guava framework developers avoid it:

Reading my DZone blogs today the top article was this very topic, demonstrating the use (in code) of ‘Optional’, which has made it’s way into the Java 8 VM.

And beware of those NULLs!



IntelliJ, Java 8 Refactoring, and Lambda/Stream Performance

My Twitter feed served up this delicious blog:

IntelliJ IDEA Inspection Settings for Java 8 Refactoring

My shop is using IntelliJ and we are converting our Java 6 projects (Inherited from an outsourced vendor 2 years ago) to run on Java 8.  Jetbrains built in some great IDE functionality every developer needs to check-out.

That also generated this question to mind: what about performance?  Lambdas and the Stream API make the code oh-so awesome to read, but is it efficient compared to verbose Java?  I found this nifty blog:

Benchmark: How Misusing Streams Can Make Your Code 5 Times Slower

Benchmarks tend to be pretty treacherous and it’s super hard to get it right.

… it showed {Lambdas and Stream API } … can be around 5 times worse {performance}

The operative words here are “misusing” and “can be” … 

Happy Coding
