Jan 31	comment	What are the features required for Object Orientation? I have often heard this same definition but I have to confess that, as a language nerd, I detest it. Encapsulation is not unique to OO (ADTs came first) and many OO languages do encapsulation by convention. Inheritance is a nice feature but its not essential (composition often does the same job; interface inheritance doesn't really count). I do agree with the polymorphism bit but it saddens me that it is rarelly distinguished from other forms of polymorphism (like parametric polymorphism, aka generics). Thankfully, the wikipedia list that S.Lott brings up has most of my rant covered :)
Jan 31	comment	What are the features required for Object Orientation? Abstract Data Types, data modeling and encapsulation are not unique to OO, though (as you briefly mention yourself). I would prefer to describe OO based on its more unique features (dynamic binding of method calls, polymorphism via said method calls, etc)
Jan 31	comment	What are the features required for Object Orientation? I shall not today attempt further to define the kinds of material I understand to be embraced within that shorthand description ["object-oriented programming"]; and perhaps I could never succeed in intelligibly doing so. But I know it when I see it, and the code example involved in this case is not that.
Dec 30	comment	Does it hurt to learn bits of many programming languages? Well, learning more doesn't hurt, does it? :)
Dec 27	comment	Two HTML elements with same id attribute: How bad is it really? What about HTML5? There is a big difference between what is written in the HTML4 spec and what is accepted by browsers, etc.
Dec 27	comment	Is there an IDE for python that creates the same kind of reflective environment that Smalltalk provides? Well, the command line REPL works on LINUX at least (thats what I use anyway).
Dec 26	comment	Is there an IDE for python that creates the same kind of reflective environment that Smalltalk provides? @S.Lott: I think his definition of "looks like a Smaltalk environment" is clear enough.
Dec 26	comment	Why is #include <iostream.h> bad? Problem is, are you sure you want a book from "back in the day?"
Dec 23	comment	How Much Logic in Getters @Domenic: This is a semantic and language-dependent issue. The point that an object is fit to use and provides the appropriate invariants after, and only after, it is fully built.
Dec 23	comment	How Much Logic in Getters @TMN: In a best case scenario the class should be organized in a way such that getters don't need to run operations capable of thowing exception. Minimizing the places that can throw exceptions leads to less unexpected surprises.
Dec 22	comment	What are some examples of “wartiness” making a programming language more useful? I am disappointed noone mentioned Perl yet. It takes pragmatic warts to a whole new level.
Dec 15	comment	Will I ever be able to code client-side browser code in a language of my choice? The point is more subtle - Javascript is described in a higher level then most intermediate languages so implementations get more leg room in choosing what to do. (Of course, this is not all a sea of roses - I just wanted to point out that we are not the first to think about an IL for the web and that it is not that simple)
Dec 13	comment	Why is Python recommended as an entry level programming language? At you last point: people often mix up dinamic typing with weak typing. Python is dynamically typed (types associated to values instead of variables) but is also strongly typed (so programs crash instead of silently swallowing conversion errors)
Dec 12	comment	Should I provide synonyms in an API? What if a function is known by multiple names (like foldl vs reduce, I vs id, etc?)
Dec 12	comment	What are the disadvantages of unobtrusive script patterns in web applications? I think the term "unobstrusive Javascript" was originally more for when your page can also work fine without Javascript (due to using an old browser or having it disabled). I don't know if it still as relevant now given how most people now use Javascript compatible browsers.
Dec 5	comment	What hurts maintainability? Isn't this a bit tautological? :)
Dec 1	comment	Elegant ways to handle if(if else) else I don't like implicitely passing arguments as instance variables like that. You get full of "useless" instance variables and there are many ways to botch up your state and break the invariants.
Nov 29	comment	What would you do if your client required you not to use object-oriented programming? @Marcin: its true that modern FP languages are quite powerful. I just really wanted to point out the distingction between data-structurs/ADTs and OO
Nov 25	comment	Should I teach my students alloca? @AlexWebr: I was trying to refer to the function == stack frame concept that is so ingrained in C. If you program in assembly language you don't need to use "The Stack" if you don't want to.
Nov 12	comment	Is it OK to use dynamic typing to reduce the amount of variables in scope? I can also name ALGOL as a language that provides scopes. I was whining about how its not easy to "terminate" a variable's lifetime in a non nesting manner. And "reusing" a variable is not totally incompatible w/ single assignment - creating a new variable with the same name, shadowing the old one does basically the same thing (and is one of the reasons I am sad that Haskell doesn't support let, only let-rec )
