I like reading about programming theories, so could you tell me if there is any object-oriented static typed language that allow variables to have a few types? Example in pesudocode: var value: BigInteger | Double | Nil I think about way of calling methods on this object. If object value have type BigInteger | Double language could al...
For example, if you look at Facebook, they have a short blue bar on top that extends the entire width of the browser. I thought about using width:100%; but I know that it needs to have a parent element to be able to do that. ...
I have read that with a statically typed language like Scala or Haskell there is no way to create or provide a Lisp apply function: (apply #'+ (list 1 2 3)) => 6 or maybe (apply #'list '(list :foo 1 2 "bar")) => (:FOO 1 2 "bar") (apply #'nth (list 1 '(1 2 3))) => 2 Is this a truth? ...
I greatly enjoyed Douglas Crockford's recent lecture series, particularly the talk which covered the history of programming languages. I'd like to learn about this subject in more detail. Consider this question language agnostic. I'm not interested in books that teach programming. I'm interested in books which discuss decisions made dur...
(not sure if it's only a C++ thing) Exception handling is hard to learn in C++ and is certainly not a perfect solution but in most cases (other than some specific embedded software contexts) it's certainly the better solution we currently have for exception handling. What about the future? Are there other known ways to handle errors ...
what are the ideas of preventing buffer overflow attacks? and i heard about Stackguard,but until now is this problem completely solved by applying stackguard or combination of it with other techniques? after warm up, as an experienced programmer Why do you think that it is so difficult to provide adequate defenses for buffer ov...
I'm a web and Linux developer with strong experience in C, PHP and JavaScript. I'd really want to take my skills further and expand into other languages, but I'm not sure what to choose. I've considered Python, as it's very popular and is used to write a surprisingly high number of programs in Ubuntu and seems very useful to write progr...
Hello Everyone. I am trying to create a little functional programming library for Java (just to scratch my own itch). While defining the higher-order functions for Lists, Sets and Maps I have come across this problem: The functions that take a collection, and return a collection of same type have almost the same implementation, and yet ...
Years ago, I have heard that someone was about to demonstrate that every computer program could be solved with just three instructions: Assignment Conditional Loop Please I would like to hear your opinion. I mean representing any algorithm as a computer program. Do you agree with this? ...
Hi I want to practice my java language with writing codes So I need some sites for introducing me some project ideas(one of subject can be like google search engine)!! thanks ...
I frequently hear claims that Scala is much more "complex" than Java. Can anyone therefore provide an example of Java code that can't be improved by writing it in Scala, or Scala code that can be improved by writing it in Java (but not by just rewriting within Scala) By "improve", I mean that the code is better with regards to one (or ...

I recently came across a good book by Richard Stevens, his "UNIX Network Programming, Volume 1, 2nd Edition" (in C), published 1998. I was reading it for the past week & realized while practicing some of the programs, that several methods used in it are not compliant to the standards or have a bit different approach. Also reproducing the...
I'm only curious. I have already developed microcontroller software in C and Assembly. So, I can see an application for these languages. As for today, I'm specialized in information and process systems and even though C++ is object-oriented and offers powerful development capabilities, we mostly develop in .NET C#. So my question is t...

Possible Duplicate: Alternatives to JavaScript Hi there, As there are many programming languages, and you have options, that which ever language you want to work on, like you if you use C# then you have option that you can use VB.NET or C++ etc further you we have Java which can replace C# or C# that can replace Java. So we h...
It seems to me that some languages are generally being conceived as more beautiful than others. This seems to apply to all programming paradigms. Are there any abstract/paradigm-spanning characteristics which makes programmers consider a language as beautiful? Edit: If you think that there is no consensus then please don't hesitate to s...
Is it possible to design something like Ruby or Clojure without the significant performance loss in many situations compared with C/Java? Does hardware design play a role? Edit: With significant I mean in an order of magnitudes, not just ten procent Edit: I suspect that delnan is correct with me meaning dynamic languages so I changed t...
