• Any good site that teaches C++?

  - by Shinmaru

  I am searching for any good site that teaches C++, that can explain most to all things about it(general) and has a decent active community. About Me: I am new to programming(knows nothing of it, so please bare with me), I have only learned(to a very basic form) LUA scripting Language, so yes I am your complete newbie. I got interested in programming, from scripting in LUA, so you can say it was my small stepping stone, One would basically take a course in college, but not everyone is well funded for that and I can't buy books for the same said reason(yes I'm somewhat poor, only money for essentials and bills), I'm not trying to get sympathy, just stating my conditions. and Please, something in between the lines of 'Programming for Dummies'(I'm not the brightest crayon in the box), I know this will not be easy, but your help will be most appreciated. I would learn for either Windows and/or Linux/Unix. I use both. Site(s) I know: Cplusplus.org(quite inactive and tutorials are a little for the programming savvy.

• Do you think that GAE alone is enough to justify learning Python over Ruby?

  - by Cue

  Considering the fact that you don't have to get involved in setting up/buying a server or even buying a domain, do you think that fact alone is enough to choose one over the other? I don't necessarily want to work on Google App Engine, I just find it convenient when it comes to hosting/environment/etc. and wondering if that's a good enough reason to learn python. In any case, I'm not looking for a debate between python and ruby but more on Google App Engine and whether its value is enough to dictate the language you should learn.

• How can I build this payment receipt/booking application?

  - by Festus

  I'm planning to build a payment receipt/booking application for a media company with several branches in different locations. The application should be able to move data across the network/internet to a central database where the administrator/accountant in a different location will be able to see the result of the entire job for the day from each branch. Application will run on windows environment. Will be able to send result of the booking to a Point Of Sales printer for print output. Now, I'm confused about choosing the right programming language to accomplish this task. I'm between beginner/intermediate level in PHP, I know HTML/CSS and JavaScript. I have tried to do this in PHP but, I'm face with several challenges and I fear for the POS part since PHP application run on the web browser. I don't know if python will be best suited for this and how long will it take someone with my experience level to pick up python. Any suggestion will be highly appreciated.

• Why do so many people dislike C++?

  - by General K

  Beginners and professional, on blogs, in forums and chatrooms - people say it everywhere: C++ oh dear god no The short form of the question: For what reason is C++ so widely disliked and people are horrified by the imagination of using it for some project? I have been using a lot of different languages, including C++ by now, and I can only say that I really like it. I'm far more horrified by Delphi than by C++. Actually, I find it's an almost perfect, compiled language! I've been doing a lot of different projects in C++ as well, ranging from 3D video games to webservers and emulators for old video game consoles. And I still do not see the problem everyone else seems to have with it! It was hard for me to get into it of course, as it is quite complex and has a lot of depth, but after that it's simply great.

• Ruby on rails not popular in big international IT companies?

  - by maro

  I would like to ask you for advice more experienced ROR developers. I am new in programming and like to idea of ROR and I am before the decision on which programing language to specialize Java vs ROR. In the future I wish to learn for bigger international IT companies (IBM, Accenture etc.) but as I am reading their job openings, most of them are hiring Java, C++, .NET... Is the ROR used only in startups or also in bigger companies as well? What should be the reasons of their preference of Java over ROR?

• game programming career, vc++ reference and future of it [closed]

  - by Pappu Bacha

  1) I have quite a lot of interest in game programming and I (to my thought) am quite good at programming skills, I have developed some console based animations and text based animation games (like copter-it, snake, and a music visualization), should I invest in game programming? I have 2 years at college left. 2) If I am to pursue a career in game programming, and I select to go only with c++ and DirectX, is it enough? is assembly language necessary? 3) is Visual C++ or MFC dead? should I invest in it or not? 4) I am unable to find any reference book for Visual C++ 2008 or later (just like C++ the complete reference book) I need a book that covers the basic fundamentals and covers the most of the libraries etc.

• Matrix camera, movement concept

  - by NoFace

  I was talking to some guy. He said that my movement concept in game is bad. When left or right arrow is pressed I'm scrolling background what makes you feel that player is moving (player's X remains same). So... he told me something about matrix view. I should create all walls and platforms static and scroll only the camera and move player's rectangle. I did a little research in Google, but nothing found. Can you tell me anything about it? How to start? Maybe links, books and resources? My programming language is Java (2d). Thank you!

• Two different domain for specific languages pointing to one site

  - by user25599

  I developing a client's blog and he needs it to be bilingual (english and spanish). Now what he wants is that users can get to the content based on the domain e.g. Jhon enters www.domain.com and he gets the english version and Juan enters www.elsenordominio.com to get the spanish version.

• Returning status code where one of many errors could have occured

  - by yttriuszzerbus

  I'm developing a PHP login component which includes functions to manipulate the User object, such as $User->changePassword(string $old, string $new) What I need some advice with is how to return a status, as the function can either succeed (no further information needs to be given) or fail (and the calling code needs to know why, for example incorrect password, database problem etc.) I've come up with the following ideas: Unix-style: return 0 on success, another code on failure. This doesn't seem particularly common in PHP and the language's type-coercion messes with this (a function returning FALSE on success?) This seems to be the best I can think of. Throw an exception on error. PHP's exception support is limited, and this will make life harder for anybody trying to use the functions. Return an array, containing a boolean for "success" or not, and a string or an int for "failure status" if applicable. None of these seem particularly appealing, does anyone have any advice or better ideas?

• Running the Ubuntu Kernel and OS on custom processor

  - by xupv5

  This is hardly a theoretical question as many have done this, albeit there's very little information on the underlying processes. I'm developing a custom MIPS-based processor on which I would like to run ubuntu. I'm quite baffled as to what to do next after you've designed the instruction set and the computer architecture itself. I need to be able to run a kernel and OS but how does it all tie in? At the moment I'm researching into designing a compiler for the linux kernel to generate the appropriate assembly language. Is that a good way to go? What do I need to do after that?

• Remmina password problem with windows server 2008 R2

  - by Hcbayram

  I use Ubuntu 12.04. I am already using Remmina both with RDP and VNC connections for several servers. For one of my servers I have a problem to login after login window opens. The server is Windows 2008 R2. The screen for entering user and password comes but does not accept the password. I guess the problem is with language but password does not contain any problematic letter except a $ sign. When connecting from Windows 7 there is no problem.

• Falsey values vs null, undefned, or empty string

  - by user687554

  I've worked with jQuery over the years. However, recently, I've found myself getting deeper into the JavaScript language. Recently, I've heard about "truthy" and falsey values. However, I don't fully understand them. Currently, I have some code that looks like this: var fields = options.fields || ['id', 'query']; I need to identify if fields is null, undefined, or has a length of 0. I know the long way is to do: if ((fields === null) || (fields === undefined) || (fields.length === 0)) { ... } My question is, is the following the same: if (!fields) { ... } Thank you!

• How to choose a good namespace name? [Linguistically]

  - by Kees C. Bakker

  English in not my native language, therefore it is a little more difficult to pick a good name for a namespace. One example to make you see my problem a bit better: We have a set of classes that have to do with the way a company is organized (we can create organizational charts with it). Currently the namespace is CFW.CoreSystem.Organizational. Is this a good name? What is linguistically the best way to name a namespace? (CFW.CoreSystem.Configuration is better than CFW.CoreSystem.Configurables). [Moved it from StackOverflow]

• Is this a typo in the Artistic License 2.0?

  - by IQAndreas

  I'm not sure if this would fit better in StackExchange/English, but regardless, there is no practical use to the answer, other than to cure my curiosity. Note this sentence at the end of the Artistic License 2.0: THE PACKAGE IS PROVIDED BY THE COPYRIGHT HOLDER AND CONTRIBUTORS "AS IS' AND WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES. It does not affect any legal aspects of the license, but is there a reason they mixed the use of single and double quotes on AS IS? The license is so new that this wouldn't have been for "command prompt friendly" reasons. Is there special use or meaning behind this in the English language, or was it a typo?

• Any Programming Languages Recommendations? A Space shooter game that allows two people to play at the same time?

  - by Bombcode

  Hey Everyone, Do you remember a arcade game, that allow two people to versus or play each other? A Galaga/Gradius type game. Me and a couple of other people I know wanna make a game like this. We want to get some other opinions on what programming languages to use.(C or C++ isn't an option .). We plan to use an engine to help us build. It's gonna be a multiplayer game, so we would be handling the networking with this language as well. We are thinking about C#, Java, or Actionscript 3. Any Advice on this? And if anyone knows the arcade game I am referring to please post up :)! Edit Let me add something here, this game will be plain on computers and laptops only. We mainly wanna what's good for handling the networking and Dual screen play.

• SQL and Database: Where to start! [closed]

  - by Nizar

  First of all I just know HTML and CSS (this is my background in web development and design) and I have found that before I move to a server-side language I need to learn about databases and SQL. My first question: Do you think this order of learning is good (I mean to learn SQL after HTML and CSS)? My secod related question: Do I have to learn a lot about SQL and databases? or just the basics? and if you know any good beginners books please write their titles.

• Java - learning with a simple project

  - by phodu_insaan

  I remember when I learnt PHP, it was suggested that I code a simple blog or a forum after reading the language fundamentals and syntax. I was told/read that this would cover everything that I would learn about PHP in a beginners book. This advice was out there in a number of places, and after following and working with PHP it seems quite good advice. I am now learning Java, and reading the book Thinking in Java by Bruce Eckel. I wonder if there is any such set of similar, small projects that I could take up, that would cover all the essentials and most of what is covered in the book. Thanks.

• Should Equality be commutative within a Class Hierachy?

  - by vossad01

  It is easy to define the Equals operation in ways that are not commutative. When providing equality against other types, there are obviously situations (in most languages) were equality not being commutative is unavoidable. However, within one's own inheritance hierarchy where the root base class defines an equality member, a programmer has more control. Thus you can create situations where (A = B) ? (B = A), where A and B both derive from base class T Substituting the = with the appropriate variation for a given language. (.Equals(_), ==, etc.) That seems wrong to me, however, I recognize I may be biased by background in Mathematics. I have not been in programming long enough to know what is standard/accepted/preferred practice when programming. Do most programmers just accept .Equals(_)may not be commutative and code defensibly. Do they expect commutativity and get annoyed if it is not. In short, when working in a class hierarchy, should effort me made to ensure Equality is commutative?

• Programming Carreer. What should i choose? [closed]

  - by thenewbie

  I have an experience in programming. Im not that experience but i have created some desktop application like payroll etc. In web i had created some websites. Now im studying java for android. I already created an application on android and submitted it on google play.However, i feel like the excitement in creating application for android or web is gone. What i think i like is to program in c++ language. but i have a doubt mastering it. Because nowadays only a handful of company hire a c++ junior programmer. I think only in gaming industry that they would hire a c++ programmer and has an 3 or more years of xp. While in java there are lots of oppurtuniy especialy for android. and I dont have a plan studying objective c cause i dont have mac. SO what should i realy choose? thank you..

• Does anyone write games in Delphi?

  - by MDV2000

  I am a very seasoned Delphi developer (over 12 years of experience not counting my Turbo Pascal experience) and was wondering does anyone write games in Delphi? I have seen DirectX API wrappers in Delphi that allow you to program against DirectX (even wrote a simple solitaire game with a friend), but haven't seen anything out there that shows me that I should keep up with Delphi. I just hate to walk away from so much knowledge and Object Pascal language, but I am not seeing much as to a reason to keep going with Delphi. I currently program in C# and thinking about XNA, but it seems to me that the dominating opinion is go C/C++ route with DirectX. Any other Delphi developers out there struggle with this too? Thanks, MDV
