comment Who extends interfaces? And why?
@overexchange If you understand... it doesn't make sense. I only see that you are trying to offend me. What did you want to say?

comment How was the system clock first used in early computers?
@DanPichelman Sharptooth is right - first computers appeared during WW2 and were intended for war, not commerce.

comment How was the system clock first used in early computers?
The first computers were extremely expensive. And were not toys. All of them were done for real work. There were toy languages and systems, without supporting HW. (but minus is not mine)

comment Extending a struct. Using helper classes rather than composition
Helper classes are not evil. The article mentioned uses logical fallacies. So, really it is NOT the subject of discussion. But still I'll give an example. If you want to extend the functionality for the non-extendable classes, for example, String, the helper classes are the only solution. Oh, since Java 8 the interfaces can serve, too. It is only one example, but there are many of them.

comment Why is first column of list called 0th in so many languages?
@Doval 2. What compile time? Many languages are interpreted ones. 1. What are you arguing for and against? I am asking this for the third time. You are merely continuing absolutely senseless discussion, jumping from one pointless argument to another.

comment Why is OOP difficult?
It depends on the language - in SmallTalk the distance (and everything) IS an object. But in C# you have mentioned it would be bad.

comment Why is OOP difficult?
A pair of points or objects should be regarded as an object. And distance should be taken as a function from the object. Using objects does not mean you make object from everything.

@Doval But the offset will be done. That is the difference. And again, where are the points you are arguing for and against? I can't notice them.

@Doval You are really funny. 1. You are proving the qualities of C thinking basing on C thinking. Base on machine code point of view. 2. What you are arguing against? Where is your point? I don't see it.

As for intervals, yes, but for segments, it would end at Nth element for 1-based addresation. Why intervals are so important? As for your definitions, they are irrelevant. For 1-based address you'll still have to substract size(element) in machine code.

comment How to handle hidden folders on deployed website
You should exactly set the technologies you are using. "The software recommends..." - What software? How does it recommend anything?

comment What should be used to diagram an application's internal architecture?
Yes, start from component diagram and maybe afterwards you will develop some part of it into a deployment diagram.

comment What UML diagram should be used for modelling permissions/users/files in Linux?
The problem is, that I have a set of objects and packages. And the rights are applied to them. So, according to you, I should use Use Case diag for actor figure only, but mostly use elements from component/package/class/object diagrams.

comment Is Java still king of cross-platform compatibility? Is the answer still Swing?
Since Dec 2013 JavaFX supports iOS and Android. It supported Windows, MacOs and Linux before. But it is different from Swing.

comment What UML diagram should be used for modelling permissions/users/files in Linux?
@YannisRizos I am afraid that the system in this case is extremely far from being simple. And any error in permission politics in one single file will cause all the system to fail. And in your example there is not a word on permissions at all.

comment How do I prevent unknowningly duplicating code?
@Brendan You are right. And the artificial de-duplication is an excessive piece of work by itself, too. But... You see by votes, people tend to simply repeat what was told to them when they started to program. Very few ever try to think further. :-(

comment Why are scientific programming languages so weird?
@ThomasEding You have used two logical fallacies in one message. I can't consider this as an error. Rather it looks as trolling. Stop it, or I'll flag you.

comment Why are scientific programming languages so weird?
@ThomasEding "If you need a programming language to help you with your math, then bets are that you are at least at this level of mathematics" If you think you are on level to participy in any discussion, do such work as to read the rules of discussion. In wiki, for example. You are positioning yourself out of any discussion.

comment How to address the concerns of the software architect but still maintain collective code ownership?
@MaciejPiechotka I had said several times that we have many programmers and one component for a programmer. So your second part is also for some other case, sorry. I understand, that defining processes for small projects is fine and simple, but we should solve tasks that are set, not other ones that are simple.
