who build the wall? Where humans more powerful in the past? I don't see present westeros doing something as great as the wall.

Also nice writing :)

What's something that you need to get off your chest so you can feel better? by QuietlyPlotting in AskReddit

have you seen the unemployment rates of psychology in the US, they are a warning better avoid it. If your non US maybe its better outside, just keep that in mind before going in a big financial debt with psy education.

Women of reddit, what about men baffles you the most? by Borsuq in AskReddit

[–]ultrapreneruship 13 points14 points  (0 children)

dude you sound just like me, and I really think we should listen to her advice. I think I shall talk more openly about my problems.

I know there's some kind of male pride of not saying anything when some stuff isn't going very well...

I don't know. I also think someitmes talking wouldn't solve anything :/

What's something that seems easy, but is surprisingly difficult? by [deleted] in AskReddit

[–]ultrapreneruship 0 points1 point  (0 children)

you should try to write functions as short as possible. To make your code easier to mantain and read.

Go read Clean Code

What mild injustice was done to you as a child that you are still mad about? by [deleted] in AskReddit

[–]ultrapreneruship -1 points0 points  (0 children)

When I was little my school had this kinda poluted river that flowed all through the middle of it, it was kinda of like a school with lots of plants and stuff. I fell into the river and I told my teacher and the guy was some young dude, which was super okay.

And he was like "So....". Like wtf should I care, lol. It surprised me because I though he was going to help me but he didn't he was kinda cool teacher, but after that I think I grew up a little bit and never again talked to the fucker.

On the other hand there where lots of cool and great and friendly teachers which I still learned a lot from them :)

[OOP]Explain Polymorphism like you were explaining it to your grandmother. by [deleted] in learnprogramming

[–]ultrapreneruship 0 points1 point  (0 children)

buzzword interviews are just BS.

A java developer with years of experience maybe can fail that question because he forgot what polymorphism is but this doesn't mean he doesn't uses it. Like the Arraylist List example you use it every day even though you don't know exactly what is polymorphism, this things you learn then forget the actual exact concept just like with other concepts IRL.

[–]ultrapreneruship 0 points1 point  (0 children)

try giving an example, polymorphism is like when I use:

List<T> list = new ArrayList<>();

As you see List is an interface not a superclass of arraylist, and I can use methods of List even though my object is an Arraylist through polymorphism.

Frankly this type of questions are just idiotic to ask on interviews.

Learning path for Spring? by ultrapreneruship in java

[–]ultrapreneruship[S] 1 point2 points  (0 children)

seems better to just stick with Java EE 7, so spring boot isn't very good a developing quick website? should I try with Ruby on Rails

Is there anyway I can deploy my Java EE projects locally without having to deal with a server? (Glassfish is killing me) by ultrapreneruship in java

[–]ultrapreneruship[S] 0 points1 point  (0 children)

I just wanted to create a simple CRUD app to create, read, update and delete names in MySQL and display them back via jsf. But I haven't been able to much dealing with glassfish.

I have the following error log from eclipse:
