  • Advise on effectively re-entering CPP world [closed]

    - by Aadith
    I am getting back into C++ world after nearly a decade. Apparently, there has been a world of development. Would like to get the developer community's advice as to what would be a good approach to have a smooth take-off. To start with, I have done the following: Read up (very briefly) on C++ 11 standards Installed GCC 4.7 Wrote a Hello World program I am sure getting a decent book and reading through it would do. But I am looking for any strategic advise experts might have to share. Trying to leverage on past experience to have a short but effective initial learning span. What would be top few things I would have to look into?

  • Baby's first big CPP project - please help [closed]

    - by jamesson
    So, I need to do a few things to the code here; http://64.90.55.88/SynapseSource-Win.zip What I need to do 1)remove the opengl output window 2)Make it work with latest openni (http://75.98.78.94/default.aspx) - as far as I could tell it only works with a specific older version 3)Improve ram and cpu usage (assuming I don't get what I need from the first two changes) 4)Eventually rebuild it as an object in this sdk; http://cycling74.com/products/sdk/ I tried going through the documentation, but "the needle could not penetrate", alas. For example, I am still unclear about some basic things; a) what are the relative responsibilities of nite vs openni? b) which xml files are always used when the app launches, and what is their format? Many thanks in advance Joe Stavitsky

  • What programming language is good for a beginner and for a hobby? [closed]

    - by Lawrence
    Possible Duplicates: What is the easiest language to start with? What programming language should I choose for an independent study language? Well as the title says what language is good for a beginner and for a hobby? I'll probably be making some games or desktop apps with a gui most likely. I'll be working in Windows and Linux. Oh and could you also give some links to tutorials for the language?

  • linking c++ sources in iPhone project

    I have a single cpp file added to my iPhone project with a .cpp extension, but I'm seeing errors when linking like: operator new[](unsigned long)", referenced from: ___gxx_personality_sj0", referenced from: I thought as long as I named the cpp files with .cpp or .mm it would do the right thing, do I need to add some linker flags?

  • Unix - "xargs" - output "in the middle" (not at the end!)

    - by Petike
    Hello, example use of "xargs" application in Unix can be something like this: ls | xargs echo which is the same as (let's say I have "someFile" and "someDir/" in the working dir): echo someFile someDir so "xargs" take its "input" and place it "at the end" of the next command (here at the end of echo). But sometimes I want xargs to place its input somewhere "in the middle" of next command. For example: find . -type f -name "*.cpp" -print | xargs g++ -o outputFile so if I had in the current directory files "a.cpp" "b.cpp" "c.cpp" the output would be the same as with the command: g++ -o outputFile a.cpp b.cpp c.cpp but I want to have something like this: g++ a.cpp b.cpp c.cpp -o outputFile Is there a way to do it? P.S.: I need it in some cases, because e.g.: i586-mingw32msvc-g++ -o outputFile `pkg-config --cflags --libs gtkmm-2.4` a.cpp b.cpp c.cpp doesn't work but this one works fine: i586-mingw32msvc-g++ a.cpp b.cpp c.cpp -o outputFile `pkg-config --cflags --libs gtkmm-2.4` Thanks.

  • How can I teach a know-it-all beginner programmer?

    - by Liran Orevi
    I need to teach a teenage beginner programmer (private tutoring style). The problem is that despite their poor knowledge and skills, they are sure of their abilities, to the point where I find it hard to teach them "better ways". What's the best way to tackle this? Just to be clear what I'm talking about: Constantly changing between tools/IDEs/libraries when it's tough. Blind certainty that really bad designs are really very good. Copying and pasting from the Internet, without understanding the code, and "marking" it as a project.

  • How to learn Ruby on Rails as a complete Programming Beginner?

    - by Alex
    I want to build a scalable dynamic Web Application. I have never programmed an Object Oriented language before. Or, let's just say I am completely new to programming, because the previous experiences aren't worth talking about. I know I have a really big task ahead of me ^^ but I wanted to get into coding for the last 10 years and now that I'm finally doing it, I would like to know how to get there in the most efficient way. Any good books/tutorials you could recommend? Would it really make sense to learn other, better documented languages before learning RoR? Or would it be better for a beginner to learn C# with ASP.NET first? Thank you for your help in advance ;-)

  • NHibernate 2 Beginner's Guide Book

    - by Ricardo Peres
    Packt Publishing has recently released a new book on NHibernate: NHibernate 2 Beginner's Guide, by Aaron Cure. I am now reading the final version, which Packt Publishing was kind enough to provide me, and I will soon write about it. I can tell you for now that Fabio Maulo was one of the reviewers, which certainly raises the expectations. In the meanwhile, there's a free chapter you can download, which hopefully will get you interested in it; you can get it from here.

  • Book Review: Oracle ADF 11gR2 Development Beginner's Guide

    - by Grant Ronald
    Packt Publishing asked me to review Oracle ADF 11gR2 Development Beginner's Guide by Vinod Krishnan, so on a couple of long flights I managed to get through the book in a couple of sittings. One point to make clear before I go into the review.  Having authored "The Quick Start Guide to Fusion Development: JDeveloper and Oracle ADF", I've written a book which covers the same topic/beginner level.  I also think that its worth stating up front that I applaud anyone who has gone  through the effort of writing a technical book. So well done Vinod.  But on to the review: The book itself is a good break down of topic areas.  Vinod starts with a quick tour around the IDE, which is an important step given all the work you do will be through the IDE.  The book then goes through the general path that I tend to always teach: a quick overview demo, ADF BC, validation, binding, UI, task flows and then the various "add on" topics like security, MDS and advanced topics.  So it covers the right topics in, IMO, the right order.  I also think the writing style flows nicely as well - Its a relatively easy book to read, it doesn't get too formal and the "Have a go hero" hands on sections will be useful for many. That said, I did pick out a number of styles/themes to the writing that I found went against the idea of a beginners guide.  For example, in writing my book, I tried to carefully avoid talking about topics not yet covered or not yet relevant at that point in someone's learning.  So, if I was a new ADF developer reading this book, did I really need to know about ADFBindingFilter and DataBindings.cpx file on page 58 - I've only just learned how to do a drag and drop simple application so showing me XML configuration files relevant to JSF/ADF lifecycle is probably going to scare me off! I found this in a couple of places, for example, the security chapter starts on page 219 but by page 222 (and most of the preceding pages are hands-on steps) we're diving into the web.xml, weblogic.xml, adf-config.xml, jsp-config.xml and jazn-data.xml.  Don't get me wrong, I'm not saying you shouldn't know this, but I feel you have to get people on a strong grounding of the concepts before showing them implementation files.  If having just learned what ADF Security is will "The initialization parameter remove.anonymous.role is set to false for the JpsFilter filter as this filter is the first filter defined in the file" really going to help me? The other theme I found which I felt didn't work was that a couple of the chapters descended into a reference guide.  For example page 159 onwards basically lists UI components and their properties.  And page 87 onwards list the attributes of ADF BC in pretty much the same way as the on line help or developer guide, and I've a personal aversion to any sort of help that says pretty much what the attribute name is e.g. "Precision Rule: this option is used to set a strict precision rule", or "Property Set: this is the property set that has to be applied to the attribute". Hmmm, I think I could have worked that out myself, what I would want to know in a beginners guide are what are these for, what might I use them for...and if I don't need to use them to create an emp/dept example them maybe it’s better to leave them out. All that said, would the book help me - yes it would.  It’s obvious that Vinod knows ADF and his style is relatively easy going and the book covers all that it has to, but I think the book could have done a better job in the educational side of guiding beginners.

  • Makefiles - Compile all .cpp files in src/ to .o's in obj/, then link to binary in /

    - by Austin Hyde
    So, my project directory looks like this: /project Makefile main /src main.cpp foo.cpp foo.h bar.cpp bar.h /obj main.o foo.o bar.o What I would like my makefile to do would be to compile all .cpp files in the /src folder to .o files in the /obj folder, then link all the .o files in /obj into the output binary in the root folder /project. The problem is, I have next to no experience with Makefiles, and am not really sure what to search for to accomplish this. Also, is this a "good" way to do this, or is there a more standard approach to what I'm trying to do?

  • Is my first employer expecting too much?

    - by priyank patel
    This is my first job as a programmer. I am working using the followig technologies: ASP.NET C# HTML CSS Javascript JQuery I work for a firm which develops software for small banking firms. Currently they have their software running in 100 firms. Their software is developed in Visual Fox Pro. I was hired to develop an online version of this software. I am the only developer. My boss is another developer, the only other developer in the firm. Therefore, my employer has a total of two developers. My boss does not have any experience with .NET development. I have been working on this project for 8 months. The progress is there, but has been very slow. I try my best to do what my boss asks. But the project just seems too ambitious for me. The company has not done have any planning for the project. They just ask me to develop what their older software provides. So I have to deal with front end, back end, review code, design architecture, and more. I have decided to give my best. I try a lot. But the project sometimes just seems to be overwhelming. Question: Is it normal for a beginner programmer to be in this place? Are my employers just expecting too much of a new programmer? As a programmer, am I lacking skills one needs to deal with this? I always feel the need to work in at least a small team, if not big one. I am just not able judge my condition. Also I am paid very low salary. I do work on Saturday as well. Please, help to clarify my judgment. Any suggestions are welcome.

  • Advice for beginner programmer

    - by user3461957
    I am beginner in software development. I noticed when I try to learn one technology let's say .NET I loose my grip over other for example Java. I thought it would be better to concentrate on one technology either Java or .NET to make significant advancement and be an expert, because they can be many details which one can ignore when keeps on changing between technologies. Is my decision right? Do experts choose this approach? Update: Should I pursue my career knowing one technology or not?
