  • Where can I find Python tutorials aimed at people who are already programmers?

    - by Chris R
    I'm a reasonably skilled programmer, and I'm interested in branching out into some new languages -- python, specifically -- but frankly I do NOT want to go through a tutorial that assumes I know nothing about programming. I want a tutorial -- again, preferably for python -- that assumes I'm just unfamiliar with the language itself and describes the ways I can use the language to solve problems. Does such a beast exist? I mean, other than the Python wiki?

  • How do machine code instructions get transferred to the CPU?

    - by user3711789
    I'm currently investigating what the runtime of different programming languages looks like behind the scenes. For a compiled language like C, people usually give the explanation of "Code is compiled to assembly which is assembled and linked into a binary executable. The executable is then loaded into memory and the CPU interprets it." My question is how does the CPU know where to look for the next instruction to execute? Is it a memory address stored in one of the registers?

    In win32 programming in C: Whats the best way to execute a win32 console program within another win32 program, and have the program that started the execution capture the output? At the moment I made the program redirect output to a file, but I am sure I must be able to open some sort of pipe?

  • Is N-Tier Architecture only the physical seperation of code or there is something more to it?

    - by Starx
    Is N-Tier Architecture only the physical separation of code or there is something more to it? What sorts of coding do we put in Presentation Layer, Application Layer, Business Logic Layer, User Interface Logic, Data Access Layer, Data Access Object,? Can all the layers mentioned above give a fully functional N-tier architecture? For example: Whenever a user clicks a button to load a content via AJAX, they we do coding to fetch a particular HTML output and then update the element, so does this JavaScript coding also lie on a different tier? Because If N-tier Architecture is really about physical separation of code, than i think Its better to separate the JavaScript coding also.

  • What should students be taught first when first learning sorting algorithms?

    - by Johan
    If you were a programming teacher and you had to choose one sorting algorithm to teach your students which one would it be? I am asking for only one because I just want to introduce the concept of sorting. Should it be the bubble sort or the selection sort? I have noticed that these two are taught most often. Is there another type of sort that will explain sorting in an easier to understand way?

  • Parsing Range Expressions

    - by sameer karjatkar
    I have a string (R(46 - 9900)) AND ( NOT (R(48 - 9900))) where R denotes Range . If you evaluate the expression it results in R(46-47) , considering the logical operators (AND,NOT). I have a requirement where I need to parse such a string and evaluate it to a correct result . I have to use C++ as a programming tool to achieve this result . Can anyone suggest a few guide lines as to how do I proceed on this ?

  • Final Integration Testing for Q.A.

    - by CalebHC
    A medium sized rails app that our company has been working on is getting close to the end of development and we are going to start doing Q.A. testing on it. We've have been writing unit, functional and integration tests all along and our test coverage is about 99% (even though that really doesn't mean anything). We feel like we have a pretty good test suite but I was wondering if we should be writing final integration tests for every little action we are going to do during our Q.A. process. If so, would using Shoulda or Cucumber be a good idea? We haven't used either of those testing tools yet, but they sound really great. Any ideas or thoughts would be really helpful. Thanks

  • How to show a live Presentation from an Android phone?

    - by Pentium10
    This is not closely related to programming stuff, so I marked as community wiki. I am wondering how can I show a live Presentation from an Android phone? I want to put on a big screen my app, while I am presenting at a conference. I will directly interact with the phone during the presentation and I want the mobile screen visible on the big screen. Are there any apps that does this, or this is possible by the USB cable?

  • Is there a C++ cross platform key/value API or library for C++?

    - by Tim
    We want to persist some user settings int he GUI part of our code. I used to do Win32 programming exclusively and the typical way this was done was with registry settings. I assume that this should be done with configuration files, but was wondering if there was a library or cross platform wrapper that made key/value pair persistence very easy.

  • Class works without declaring variables?

    - by Maxim Droy
    I'm learned php as functional and procedure language. Right now try to start learn objective-oriented and got an important question. I have code: class car { function set_car($model) { $this->model = $model; } function check_model() { if($this->model == "Mercedes") echo "Good car"; } } $mycar = new car; $mycar->set_car("Mercedes"); echo $mycar->check_model(); Why it does work without declaration of $model? var $model; in the begin? Because in php works "auto-declaration" for any variables? I'm stuck

  • Antique Software [closed]

    - by Antique
    Will software ever be considered "antique"? In other words, is a stack of punch cards worth anything? (Perhaps if they were made by someone special, or the program on them was some type of programming milestone?) What about modern software?

  • Rails - How do you dynamically call the request methods "get put destroy etc" at runtime in tests

    - by adam
    I'm always writing tests to check my controller restricts people from certain actions depending on their status i.e. logged in, admin? etc Regardless of whether its a get to :index or a puts to :create the code is always the same. I'm trying to refactor this so that i have one method such as should_redirect_unauthenticated_to_login_action(request, action) and call it like so should_redirect_unauthenticated_to_login_action(:get, :index) = get :index But not sure how to dynamically call the various response methods rails provides for functional tests which seem to live in the module ActionController I mucked around with module = Kernel.const_get("ActionController") module::TestProcess.get NoMethodError: undefined method `get' for ActionController::TestProcess:Module can anyone help (im very new to dynamic calling in ruby)
