  • Books or help on OO Analysis

    - by Pat
    I have this course where we learn about the domain model, use cases, contracts and eventually leap into class diagrams and sequence diagrams to define good software classes. I just had an exam and I got trashed, but part of the reason is we barely have any practical material, I spent at least two good months without drawing a single class diagram by myself from a case study. I'm not here to blame the system or the class I'm in, I'm just wondering if people have some exercise-style books that either provide domain models with glossaries, system sequence diagrams and ask you to use GRASP to make software classes? I could really use some alone-time practicing going from analysis to conception of software entities. I'm almost done with Larman's book called "Applying UML and Patterns An Introduction to Object-Oriented Analysis and Design and Iterative Development, Third Edition". It's a good book, but I'm not doing anything by myself since it doesn't come with exercises. Thanks.

  • eBook editions of programming books

    - by Jon Hopkins
    (I'll get my justification for why this is on topic in early: programming books tend to have fairly specific formatting needs - code samples, tables, images and graphs - which are not common to all book types and are not necessarily well handled by eBook readers. Similarly they're used in different ways - you often dip in and out rather than read cover to cover.) I've just noticed that Don't Make Me Think by Steve Krug is available as an eBook edition for the Kindle (and presumably also for other readers) which set me thinking. There are certain advantages to eBook readers for tech books - primarily that you can carry a massive library of what would be heavy physical books around very easily. The downside is that certain eBook readers allegedly aren't particularly well equipped to cope with tables, code samples and so on and a book like Don't Make Me Think presumably makes extensive use of these sorts of things. So, the question, what are your experiences of reading and using programming books on an eBook reader and would you recommend it? I'm specifically interested in the latest generation Kindle but happy to hear about all devices - might be useful to state which one you use in the answer.

  • Introducing Programming To a Mathematician

    - by ell
    I currently am a programmer, I'm almost 16 years of age and have pretty much narrowed my careers down to something involving a Computer Science degree or Electrical Engineering degree (I know they are quite different but this question is about my friend) but my friend isn't so sure. He is very interested in maths and is very good at it and I think he would enjoy programming but he isn't willing to try it (edit he is willing to try but has never done before). Can anyone give me an suggestions for a language or tool that he could dabble in programming (at a reasonably basic level I assume) to solve maths problems or involve some kind of maths. As I say he enjoys maths a lot but I think he would enjoy programming, the problem is I don't want him to be put off by the stuff that isn't relevant at introductory levels such as memory allocation et al. I know that is very important but the point is that I want him to learn a bit of programming with maths then hopefully if he is interested enough he can start learning programming as programming. Thanks in advance, ell. Edit: Its not that he's completely uninterested - more that he hasn't actively explored the area before, maybe because he isn't informed about it. I wouldn't want to force him to do something he doesn't want to, I see this as more of a little push so that he can learn about programming. If he doesn't like it - fair enough, I can't control that and don't want to but if he turns out to enjoy it - this push will have been the right thing.

  • Bitbucket and a small development house

    - by Marlon
    I am in the process of finally rolling Mercurial as our version control system at work. This is a huge deal for everyone as, shockingly, they have never used a VCS. After months of putting the bug in management's ears, they finally saw the light and now realise how much better it is than working with a network of shared folders! In the process of rolling this out, I am thinking of different strategies to manage our stuff and I am leaning towards using Bitbucket as our "central" repository. The projects in Bitbucket will solely be private projects and everyone will push and pull from there. I am open to different suggestions, but has anyone got a similar setup? If so, what caveats have you encountered?

  • Can I use a project code which has New BSD license but uses a GPL license library?

    - by Alok Kulkarni
    I want to use the ICSOpenVpn project source code in my commercial application. If we see the ICSOpenVpn project, it states that its license is New BSD but the libopenvpn.so library it uses is under GNU GPLv2 license. As per FAQ for version 2 of GNU GPL "If a library is released under the GPL (not the LGPL), does that mean that any program which uses it has to be under the GPL?" The answer says: "Yes, because the program as it is actually run includes the library." Also, how could ICSOpenVpn change the license to New BSD?

  • No specific goal for building web applications but could be in the next few months! so, which web server side language is better for me? [closed]

    - by Goma
    I didn't put a specific goal for building websites and web applications yet, but I will may know where I am going exactly in the next few months. Generally I am looking for good web development language that I don't need to change at least in the next 5 years. I want it to serve me in dfferent categories, for building small websites, medium websites and it could help me in finding a good job or working as a freelancer. Any suggestions?

  • Should my colleagues review each others code from source control system?

    - by Daniel Excinsky
    Hi everybody. So that's my story: one of my colleagues uses to review all the code, hosted to revision system. I'm not speaking about adequate review of changes in parts that he belongs to. He watches the code file to file, line to line. Every new file and every modified. I feel just like being spied on! My guess is that if code was already hosted to control system, you should trust it as workable at least. My question is, maybe I'm just too paranoiac and practice of reviewing each others code is good? P.S: We're team of only three developers, and I fear that if there will be more of us, colleague just won't have time to review all the the code we'll write.

  • Building a database class in PHP

    - by Sprottenwels
    I wonder if I should write a database class for my application, and if so, how to accomplish it? Over there on SO, a guy mentioned it should be written as an abstract class. However, I can't understand why this would be a benefit. Do I understand correctly, that if I would write an abstract class, every other class that methods will need a database connection, could simply extend this abstract class and have it's own database object? If so, how is this different from a "normal" class where I could instantiate an database object? Another method would be to completely forget about my own class and to instantiate a mysqli object on demand. What do you recommend?

  • Correct definition of the term "Yak Shaving"

    - by StevenWilkins
    The wiktionary has two different definitions: Any apparently useless activity which, by allowing you to overcome intermediate difficulties, allows you to solve a larger problem. The actually useless activity you do that appears important when you are consciously or unconsciously procrastinating about a larger problem. This post defines it as: yak shaving is what you are doing when you're doing some stupid, fiddly little task that bears no obvious relationship to what you're supposed to be working on, but yet a chain of twelve causal relations links what you're doing to the original meta-task. I personally prefer the final definition because it contains the word "fiddly" which I think perfectly describes a typical yak shaving task. What is the best definition you've come across or can provide?

  • Is there an established or defined best practice for source control branching between development and production builds?

    - by Matthew Patrick Cashatt
    Thanks for looking. I struggled in how to phrase my question, so let me give an example in hopes of making more clear what I am after: I currently work on a dev team responsible for maintaining and adding features to a web application. We have a development server and we use source control (TFS). Each day everyone checks in their code and when the code (running on the dev server) passes our QA/QC program, it goes to production. Recently, however, we had a bug in production which required an immediate production fix. The problem was that several of us developers had code checked in that was not ready for production so we had to either quickly complete and QA the code, or roll back everything, undo pending changes, etc. In other words, it was a mess. This made me wonder: Is there an established design pattern that prevents this type of scenario. It seems like there must be some "textbook" answer to this, but I am unsure what that would be. Perhaps a development branch of the code and a "release-ready" or production branch of the code?

  • Which open source PHP project has the 'perfect' OOP design I can learn from?

    - by aditya menon
    I am a newbie to OOP, and I learn best by example. You could say this question is similar to Which Scala open source projects should I study to learn best coding practices - but in PHP. I have heard-tell that Symfony has the best 'architecture' (I will not pretend I know what that exactly means), as well as Doctrine ORM. Is it worth it to spend many months reading the source code of these projects, trying to deduce the patterns used and learning new tricks? I have seen equal number of web pages dissing and liking Zend's codebase (will provide links if deemed necessary). Do you know of any other project that would make any veteran OOP developer shed tears of joy? Please let me add that practicality and scope of use is not a concern at all here - I just want to do: Pick a project that has a codebase deemed awesome by devs way better and greater than me. Write code that achieves what the project does. Compare results and try to learn what I don't know. Basically, an academic interest codebase. Any recommendations please?

  • Rewriting code under BSD license

    - by Frank
    I am currently studding OpengGL with OpenGL Supebible 5th edition. I've found interested for me some C++ code that is distributed with the book (see also on google code). That code is under New BSD License. I am writing my software on C# with SharpGL wrapper and I'd like to know following things: Can I rewrite that C++ to C#? edid: I'am interesting in using such things like GLBatch, GLShaderManager and some other thing from GLTools. Problem is that library is on C++, but I use C#. How do I have to mark my source code if I put it somewhere like to my github account? What disclaimer should be?

  • What simple game is good to learn OO principles?

    - by Bogdan Gavril
    I have to come up with a project propsal for my students, here are some details: The design should be gove over OO concepts: encapsulation, interfaces, inheritance, abstract classes Idealy a game, to keep interest high No GUI, just the console Effective time to finish this: ~ 6 days (1 person per proj) I have found one nice example of a game with carnivore and herbivore cells in a drop of water (array), it's a game of life twist. It is a bit too simple. Any ideeas? Aditional info: - language is C#

  • What programming languages should every computer science student be taught?

    - by Anto
    What languages (or classes (as in paradigms) of programming languages, plus a recommended language of that class) should every computer science student be taught in college according to you? Motivate your answers; why that language? What use will one have from it? What concepts does it teach (better than language X does)? Note/clarification: This question is about computer science with heavy focus on software engineering, not pure computer science. It is still computer science education and not software engineering education which is the focus.

  • What is the way to understand someone else's giant uncommented spaghetti code? [closed]

    - by Anisha Kaul
    Possible Duplicate: I’ve inherited 200K lines of spaghetti code — what now? I have been recently handled a giant multithreaded program with no comments and have been asked to understand what it does, and then to improve it (if possible). Are there some techniques which should be followed when we need to understand someone else's code? OR do we straightaway start from the first function call and go on tracking next function calls? C++ (with multi-threading) on Linux

  • Gerrit, git and reviewing whole branch

    - by liori
    I'm now learning Gerrit (which is the first code review tool I use). Gerrit requires a reviewed change to consist of a single commit. My feature branch has about 10 commits. The gerrit-prefered way is to squash those 10 commits into a single one. However this way if the commit will be merged into the target branch, the internal history of that feature branch will be lost. For example, I won't be able to use git-bisect to bisect into those commits. Am I right? I am a little bit worried about this state of things. What is the rationale for this choice? Is there any way of doing this in Gerrit without losing history?

  • Best practices for managing deployment of code from dev to production servers?

    - by crosenblum
    I am hoping to find an easy tool or method, that allow's managing our code deployment. Here are the features I hope this solution has: Either web-based or batch file, that given a list of files, will communicate to our production server, to backup those files in different folders, and zip them and put them in a backup code folder. Then it records the name, date/time, and purpose of the deployment. Then it sends the files to their proper spot on the production server. I don't want too complex an interface to doing the deployment's because then they might never use it. Or is what I am asking for too unrealistic? I just know that my self-discipline isn't perfect, and I'd rather have a tool I can rely on to do what needs to be done, then my own memory of what exact steps I have to take every time. How do you guys, make sure everything get's deployed correctly, and have easy rollback in case of any mistakes?

  • Complex algorithm for complex problem

    - by Locaaaaa
    I got this question in an interview and I was not able to solve it. You have a circular road, with N number of gas stations. You know the ammount of gas that each station has. You know the ammount of gas you need to GO from one station to the next one. Your car starts with 0. The question is: Create an algorithm, to know from which gas station you must start driving. As an exercise to me, I would translate the algorithm to C#.

  • Significance and role of Node.js in Web development

    - by Pankaj Upadhyay
    I have read that Node.js is a server-side javascript enviroment. This has put few thought and tinkers in my mind. Can we develop a complete data-drivent web application utilizing just JavaScript (along with node.js), HTML5 and CSS? Do we still need to use some server-side scripting language (e.g. C#, PHP)? In case we still need to use other scripting languages, what is node.js worth for, or useful? NOTE: Pardon with my knowledge about node.js.

  • How do I encrypt the source code on the webserver?

    - by Ashin k n
    I have a web application developed using Python, HTML, CSS & JavaScript. The customer installs it in any of their own Machine and uses it through their LAN. In short the customer sets up the webserver in any of their own machine. Since its a web application, all the source code is open for the customer in the document root directory of webserver. I want to encrypt the whole source code in the document root directory in such a way that it should not effect the working of the web application. Is there is any way to encrypt the Python, HTML, CSS & JavaScript for this purpose.

  • Staying OO and Testable while working with a database

    - by Adam Backstrom
    What are some OOP strategies for working with a database but keeping thing testable? Say I have a User class and my production environment works against MySQL. I see a couple possible approaches, shown here using PHP: Pass in a $data_source with interfaces for load() and save(), to abstract the backend source of data. When testing, pass a different data store. $user = new User( $mysql_data_source ); $user-load( 'bob' ); $user-setNickname( 'Robby' ); $user-save(); Use a factory that accesses the database and passes the result row to User's constructor. When testing, manually generate the $row parameter, or mock the object in UserFactory::$data_source. (How might I save changes to the record?) class UserFactory { static $data_source; public static function fetch( $username ) { $row = self::$data_source->get( [params] ); $user = new User( $row ); return $user; } } I have Design Patterns and Clean Code here next to me, but I'm struggling to find applicable concepts.

  • What are the options for setting up a UNIX environment to learn C using Kernighan and Richie's The C Programming Language?

    - by ssbrewster
    I'm a novice programmer and have been experimenting with Javascript, jQuery and PHP but felt I wasn't getting a real depth of understanding of what I was doing. So, after reading Joel Spolsky's response to a question on this site (which I can't find now!), I took it back to basics and read Charles Petzold's 'Code' and am about to move onto Kernighan and Richie's The C Programming Language. I want to learn this in a UNIX environment but only have access to a Windows system. I have Ubuntu 12.04 running on a virtualised machine via VMWare Player, and done some coding in the terminal. Is using a Linux distro the only option for programming in a UNIX environment on Windows? And what are the next steps to start programming in C in UNIX and where do I get a compiler from?

  • I'm learning html and I'm confused as to how href's work. [migrated]

    - by Robolisk
    Okay so i'm learning html right now and soon css. In my html coding I have a section like this for navigation: <div id="header"> <h1>Guild Wars 2 Fanbase</h1> <ol id="navigation"> <li><a href="/">Home</a></li> <li><a href="/facts">Facts</a></li> <li><a href="/gallery">Gallery</a></li> <li><a href="/code">Coding</a> <ul><li><a href="/code/line">Lines</a></li> <li><a href="/code/comment">Comment Lines</a></li> </ul> </li> </ol></div> Now when I open up this .html file this is all layed out the way I want it too look (the mark up that is). My question is this, when I click on a link on this site (this site being this code) I get an a error saying this webpage is not found, but of course. But how do I create it so I can have the web pages working together? I'm not sure how to word it correctly. Like, do I create another .html file in the same directory so somehow when I click the link it reads from the second .html file? If you not sure what I'm asking, just let me know and I'll try to be more specific. Thank you for your help (: excuse my mistakes in grammar, not the worlds best in English, trying my best (:

  • Moving from building internal applications as WPF to ASP NET MVC?

    - by stuartmclark
    I have worked on quite a few internal applications for my work and I have always defaulted to using WPF, but I am considering re-writing existing ones into a web app. This is so that anyone in my company can use it without having to download anything from the network. I am just wondering if this is the way forward with any development of new internal applications? So, should I stop using WPF and start using ASP.NET MVC for internal applications that a lot of people need to use?

  • UML class diagram - can aggregated object be part of two aggregated classes?

    - by user970696
    Some sources say that aggregation means that the class owns the object and shares reference. Lets assume an example where a company class holds a list of cars but departments of that company has list of cars used by them. class Department { list<Car> listOfCars; } class Company { list<Car> listOfCars; //initialization of the list } So in UML class diagram, I would do it like this. But I assume this is not allowed because it would imply that both company and department own the objects.. [COMPANY]<>------[CAR] [DEPARTMENT]<>---| //imagine this goes up to the car class
