I don't understand Access Modifiers in OOP. Why do we make for example in Java instance variables private and then use public getter and setter methods to access them? I mean what's the reasoning/logic behind this? You still get to the instance variable but why use setter and getter methods when you can just make your variables public? ...
Hi, I am teaching programming to my nephews and I want them to improve their skills by contributing to open source projects. Now my question is, do you know any open source project that suit for a newbie programmer. What I mean is, the project does not have a large codebase, the project is very interesting and the project is written in ...
I heard that a program can be presented as a tree. I also heard that there is a programming language whose syntax make this idea very clear. I mean that programs written in this language can be easily represented as a tree. Does anybody know what is the name of this language? ...
The company I work for has all of its legacy ("legacy" being used rather liberally in this context) code in VB.NET. They have about 6000+ lines of VB.NET code, so all of the developers are comfortable with it. We have started to develop a new product, and are finding that some modules are easier to complete in C# than in VB.NET, such as...
I'd like to experiment with a new language/framework to work on some desktop tools for myself, which will do tasks related to internet services. I.e. i'd like to to monitor some of my servers for http or icmp response, also parse xml responses. I have experience with php, lua, mysql, and basic knowledge of java and c++. I'm also inter...
Possible Duplicate: Why did we bother with line numbers at all? I'm curious about why early versions of the BASIC programming language had line numbering like in: 42 PRINT "Hello world!" The text editors back then had no line numbering? EDIT: Yes, I know they are used for GOTOs, but why? I mean having labels was too comput...
I do not have a CS degree but I have lots of intermediate experience with many languages (PHP, C#, Objective-C, Java, VBScript, Actionscript, Javascript, Ruby, etc), mostly freelance or pastime. I have a little experience with Linux (Ubuntu), and a decent bit with Windows. When I look at different languages I find that am interested in m...
As a result of a conversation with a colleague today, I've been searching (unsuccessfully) for a large'ish list of what technology stacks are being used popular websites and standalone applications today. We're aware of the big ones like Facebook (php/ ), Twitter (scala/cassandra), Youtube (python/?), Digg (php/cassandra), stackoverflow ...

We need to write a script that needs to process movies (using C-based ffmpeg) and also update our databases. Also there would be some thread programming to accomplish with a worker-manager design. I am thinking of writing this in Ruby is there any good language to do this, if so what is its primary advantage for choosing? We are based o...
Of the many other development tools I've used, nothing holds a candle to the 'Functionality to Development Effort' ratio of MS Access. The reason I am asking is that I have been out of the language selection process for a few years, working on a large .Net system, and am only anecdotally familiar with the latest development tools outsi...
Hi All Can somebody please guide me in the right direction of creating a scripting language that targets the WSH (Windows Scripting Host)? I have googled for it, but there seem to be far fewer links related to this than when I originally searched for it a few months back. THank you ...
I' ve been doing some programming lately and faced an issue which i found weird in c#. (at least for me) public class Foo { //whatever public class FooSpecificCollection : IList<Bar> { //implementation details } public FooSpecificCollection GetFoosStuff() { //return the collection } } I wa...
I'm investigating languages and IDEs for a project involving teaching high-school students (around grade 11). It will teach basics of programming as an introduction to computer science (e.g., including how numbers/strings/characters are represented, using procedures and arrays, control flow, a little bit of algorithms, only very basic I/...

I always thought that parentheses improved readability, but in my textbook there is a statement that the use of parentheses dramatically reduces the readability of a program. Does anyone have any examples? ...
I have done a few months of development with Qt (built GUI programatically only) and am now starting to work with Cocoa. I have to say, I love Cocoa. A lot of the things that seemed hard in Qt are easy with Cocoa. Obj-C seems to be far less complex than C++. This is probably just me, so: Ho do you feel about this? How does Cocoa compar...
I was wondering if programming languages and frameworks get updated in small increments or are they just x.0 releases? And if they do how do you keep up on all the changes in every update? I am specifically interested in Objective-C and Cocoa and CocoaTouch. I'm learning from books and online PDF's etc, but often they are at best a few ...
What are the main differences between Objective-C and C++ in terms of the syntax, features, paradigms, frameworks and libraries? *Important: My goal is not to start a performance war between the two languages. I only want real hard facts. In fact, my question is not related to performance! Please give sources for anything that may seem ...
I've been writing Java for the last couple of years , and now I've started to write in python (in addition). The problem is that when I look at my Python code it looks like someone tried to hammer Java code into a python format , and it comes out crappy because - well , python ain't Java. Any tips on how to escape this pattern of "Wr...
