Can anyone point me in the right direction of some facial recognition libraries & algorithms ? I've tried searching/googling but i mostly find thesises and very little real software.

What is the difference between Go's multithreading approach and other approaches, such as pthread, boost::thread or Java Threads?

How do I write an equivalent of this in Java? // C++ Code template< class T > class SomeClass { private: T data; public: SomeClass() { } void set(T data_) { data = data_; } };

This is a rather old topic: Are setters and getters good or evil? My question here is: do compilers in C++ / D / Java inline the getters and setter? To which extent do the getters/setters impact performance (function call, stack frame) compared to a dir...

Why do we say languages such as C are top-down while OOP languages like Java or C++ are bottom-up? Does this classification have any importance in software development?

Why does everyone tell me writing code like this is a bad practice? if (foo) Bar(); //or for(int i = 0 i < count; i++) Bar(i); My biggest argument for omitting the curly braces is that it can sometimes be twice as many lines with them. For...

I would like to be able to write a Java class in one package which can access non-public methods of a class in another package without having to make it a subclass of the other class. Is this possible?

My understanding is that C/C++ produces native code to run on a particular machine architecture. Conversely, languages like Java and C# run on top of a virtual machine which abstracts away the native architecture. Logically it would seem impossible for ...

Coming from C++ to Java, the obvious unanswered question is why didn't Java include operator overloading? Isn't Complex a, b, c; a = b + c; much simpler than Complex a, b, c; a = b.add(c);? Is there a known reason for this, valid arguments for not allow...

Java has generics and C++ provides a very strong programming model with templates. So then, what is the difference between C++ and Java generics?

How can the following simple implementation of sum be faster? private long sum( int [] a, int begin, int end ) { if( a == null ) { return 0; } long r = 0; for( int i = begin ; i < end ; i++ ) { r+= a[i]; } ret...

Let's say I've a string "12345" I should obtain all subsequence combinations of this string such as: --> 1 2 3 4 5 --> 12 13 14 15 23 24 25 34 35 45 --> 123 124 125 234 235 345 --> 1234 1235 1245 1345 2345 --> 12345 Please note that I grouped them in ...

How can I call Java functions from a C++ application? I know about calling them from CMD (or similar techniques), but I would rather not use them.

I always asked myself if it would be possible to make a Java to C++ converter. Maybe a tool that converts the Java syntax to the C++ syntax? I am aware that the languages differ, but simple things like loops where the semantics match 1 to 1. Is there s...

Why bitwise operation (~0); prints -1 ? In binary , not 0 should be 1 . why ?
