Mar 18	revised	I'm trying to understand hash tables - can someone explain it to me - clearly? added 1 characters in body
Mar 18	comment	How can you tell if you're really going to be working with the “smartest people”? @Dunk I do realize that smart people split large projects into smaller ones. Large Systems Suck. This rule is 100% transitive. If you build one, you suck. - Steve Yegge

Feb 22	answered	Variable names: underscores, no underscores, or camel case?
Dec 23	comment	Is there any reason to use C++ instead of C, Perl, Python, etc.? @Konrad Rudolph: please see my ohter answer above, but actually you may be right regarding garbage collectors: I'm not sure they can handle reallocations of pointers. But then it depends on the GC. Some very simple ref-counted GC's can do fine (PHP comes to mind).
Dec 23	comment	Is there any reason to use C++ instead of C, Perl, Python, etc.? @Neil G: unfortunately it's not only POD vs non-POD. The problem is that in C++ a vector element can contain pointers to locations that potentially may be affected by realloc(). The only way of keeping these pointers up to date is copying elements (during resizing of a vector), and calling copy ctors. There is no way in C++ for the vector implementation to know if a vector element in fact contains such pointers or not.
Dec 22	comment	Is there any reason to use C++ instead of C, Perl, Python, etc.? no performance overhead at runtime - that's not always true. If you look at STL vector implementations you will see that they don't take the advantage of using realloc() (they can't because of pointers, long story) whereas all higher-level languages that I know can and do use realloc() in vector impl's. This is just one example that it's not that obvious and all black-and-white.

Nov 25	comment	Why do large IT projects tend to fail or have big cost/schedule overruns? One curious thing about this problem is that you usually get completely different answers from developers and from managers.
Nov 25	awarded	Nice Answer
Nov 24	comment	How should I start with Lisp? How to start with Lisp: open as many parentheses as you can.

Nov 23	comment	What mistakes do language writers often make which doom their language? @Robert Harvey: the one that hasn't been created yet, but it might be underway, who knows. (Well, neither the question was constructive)
Nov 23	comment	What mistakes do language writers often make which doom their language? @acidzombie24: long story short, a good language gives so much flexibility that you can come up with new creative ways of using the language that would surprise even its creator. There's nothing you can do in Java or C# that would surprise their creators. Python is a slighly different story: they have this motto: "There should be one - and preferably only one - obvious way to do it." which smells same kind of dictatorship to me.
Nov 23	comment	What mistakes do language writers often make which doom their language? @Oak: Java was created as a greatly simplified, idiot-proof C++, and that was exactly Java's "killer feature".

Nov 21	comment	Collecting metrics of C++ code Aside from LOC I also use a simple shell script to measure "code bloat": size of a binary object (.o) divided by lines of code of the corresponding module and header. Not the ratio itself, but rather its growth in time gives me a sign that, for example, I'm over/misusing templates.
Nov 20	comment	“Gödel, Escher, Bach” still valid today? @Frank Shearar: looking at GEB:EGB I wonder why he didn't call it BGE:EGB (never finished the book itself to be honest)
