A comment on Inverting Binary Trees Considered Harmful.

Re:Inverting Binary Trees Considered Harmful by CamperBob2 on Thursday June 11, 2015 @11:35PM (#9703874)
This passage gives me a good idea:

  The OPower guy said they had a ton of problems where they 
  will be using Scalding, so I asked him what they are 
  doing in its absence. He said Oh we pojo it. Then he said 
  pojo this and pojo that, and soon I was drowning in 
  pojos, so I asked, Sorry, what exactly is a pojo ? Now, 
  bear in mind I am a Scala programmer and haven't touched 
  Java in ages, and they knew that. Their whole pitch was 
  they wanted to inject some new Scala blood into their 
  tired Java veins, and that's why I interviewed there. So 
  the guy is agape, and says, you don't know what a pojo is?
  When was the last time you wrote Java?
When interviewing a candidate, use some wacky made-up term like "pojo" a lot in offhand conversation, and reject anyone who doesn't ask what it is.

POJO stands for "Plain Old Java Object" and it is a somewhat common term.

http://en.wikipedia.org/wiki/Plain_Old_Java_Object

The term was coined by Martin Fowler, Rebecca Parsons and Josh MacKenzie in September 2000:[1]

"We wondered why people were so against using regular objects in their systems and concluded that it was because simple objects lacked a fancy name. So we gave them one, and it's caught on very nicely."[1]

Fowler ... what did you expect?

I was once caught out by that tactic. The interviewer asked if I would use such-and-such algorithm to solve their problem, and I said sure, whatever. I was just thinking to myself, give me the job and I'll research it and make it work. It wasn't until much later that I realized the possibility that such-and-such algorithm didn't really exist, and that I had failed the weeding-out question.

Well, someone failed, but I don't think it was you. Unless you actually lied about knowing it.

Well I didn't admit that I didn't know it - two wrongs don't make a right. This was my first interview in 8 years, second in 24 - admittedly I was a little rusty.

Good advice! POJO (not pojo) is a virtually meaningless term. It was invented to denote any class that wasn't derived from a J2EE class (J2EE was superseded by Java EE in 2006 or so). A class with 7 levels of inheritance, implementing 14 interfaces but no J2EE class/interface among them is a "plain" POJO.

pojo is a common term for java devs, at least any who have been molested by spring

It's also seen some use in the Javascript community as well (though not nearly as common).

And Ruby too (PORO naturally). Leave it to Martin Foweler et al. coin a useful [category of] term[s].

Spring continued where J2EE had ended in 2006. Spring is the new J2EE. Wherever I can I avoid it and solely use the latest Java EE without dependency to any external bloatware.

Never heard of spring, never heard of pojo. Specialized in C/C++, STL, Boost, OpenGL and GLUT, GLx... over the decade have only found interviews for Java jobs. Have tried to learn Java, used them a jobs where none of my bosses knew it or cowokers could spend time talking to me about it. Still, I can only get interviews of Java jobs because that is the only work experience on my resume. Why are we all so screwed?
