• Order of learning sort algorithms

  - by user619818

  I have already studied bubblesort, insertion sort and selection sort and can implement them in C pretty much from knowledge of the algorithm. I want to go on to learn shellsort, merge sort, heapsort and quicksort, which I guess are a lot harder to understand. What order should I take these other sort algos? I am assuming a simpler sort algo helps learn a more complex one. Don't mind taking on some others if it helps the learning process.

• Is the 'C' in MVC really necessary?

  - by Anne Nonimus

  I understand the role of the model and view in the Model-View-Controller pattern, but I have a hard time understanding why a controller is necessary. Let's assume we're creating a chess program using an MVC approach; the game state should be the model, and the GUI should be the view. What exactly is the controller in this case? Is it just a separate class that has all the functions that will be called when you, say, click on a tile? Why not just perform all the logic on the model in the view itself?

• What is your favourite/ideal development environment?

  - by Nico Huysamen

  If you could describe your ideal development environment, what would it be? There are numerous things to take into consideration, including but not limited to: Hardware Software (Operating System of Choice, Paid vs. Free Software, ...) Physical Environment (lighting, open-plan, location, ...) An endless supply of coffee... ... In other words, if you could tell your company what they could do to make your development experience there better, what would it be?

• Licensing Options for a dead project

  - by Russell Durham

  I'm currently working on a project where the original author informally told me that he didn't want to publish the source. Since then, the original author has gone leaving me to be the sole developer on the project. I've tried to contact him several times about making the project open source so that I can have other developers assist me but he is not responding to any communications. I'm not planning on trying to make money of the software, I just want a general license that allows me to put the code on GitHub or BitBucket so that other people in the community can assist me with the development. Can I do this since he is gone and not responding to any form of communication? Is there a time period I need to wait? I know what I asking for is legal advice, I just have no idea where to start looking to find the answer so I decided to start here.

• How to structure a C ,C++ questionnaire for freshers?

  - by amar

  I am primarily a programmer but one of my recent responsibility is to create a questionnaire, which has following properties. 1.Objective or very small code snippets. 2.Since target is for freshers it should test them on basics. I have to test if a fresh graduate with CS degree is good enough to be trained in mobility, to be particular iOS I have the questions i want to have a better understanding of distribution of questions.Like how much should i emphasize on memory management and how much on data structure etc what can be the best possible composition of the questionnaire. Thanku

• Is it bad to have an "Obsessive Refactoring Disorder"?

  - by Rachel

  I was reading this question and realized that could almost be me. I am fairly OCD about refactoring someone else's code when I see that I can improve it. For example, if the code contains duplicate methods to do the same thing with nothing more than a single parameter changing, I feel I have to remove all the copy/paste methods and replace it with one generic one. Is this bad? Should I try and stop? I try not to refactor unless I can actually make improvements to the code performance or readability, or if the person who did the code isn't following our standard naming conventions (I hate expecting a variable to be local because of the naming standard, only to discover it is a global variable which has been incorrectly named)

• Best Practices in Setting up a Build and Deployment environment for the Java Platform

  - by Genadinik

  I have a project for which "quick and dirty" isn't the best solution. What is the most stable and currently accepted set of procedures/tools that I should look into when setting up my build/deploy dev (and later production) environment? What I mean is: Should I use ANT? Or has there been something better that has evolved? In what instances should I use Maven? What are some best practices to create a continuous integration/deployment environment? What are best practices for doing test-driven development? Anything else?

• Learning to be a good developer: what parts can you skip over?

  - by Andrew M

  I have set myself the goal of becoming a decent developer by this time next year. By this I mean full experience of the development 'lifecycle,' a few good apps/sites/webapps under my belt, and most importantly being able to work at a steady pace without getting sidelined for hours by some should-know-this-already technique. I'm not starting from scratch. I've written a lot of html/css, SQL, javascript, python and VB.net, and studied other languages like C and Java. I know about things like OOP, design patterns, TDD, complexity, computational linguistics, pointers/references, functional programming, and other academic/theoretical matters. It's just I can't say I've really done these things yet. So I want to get up to speed, and I want to know what things I can leave till a later date. For instance, studying algorithms and the maths behind them is interesting and all, but so far I've hardly needed to write anything but the most basic nested loops. Investigating Assembly to have a clearer picture of low-level operations would be cool... but I imagine rarely infringes on daily work. On the other hand, looking at a functional programming language might help me write programs that are more comprehensible and less prone to hidden failures (at the moment I'm finding the biggest difficulty is when the complexity of the app exceeds my capacity to understand it - for instance passing data around was fine... until I had to start doing it with AJAX, which was a painful step up). I could spend time working through case studies of design patterns, but I'm not sure how many of them get used in 'real life.' I'm a programmer with basic abilities - what skills should I focus on developing? (also my Unix skills are very weak, and also knowledge of Windows configuration... not sure how much time I should spend on that)

• Patterns to refactor common code in multi-platform software

  - by L. De Leo

  I have a Django application and a PyQt application that share a lot of code. A big chunk of the PyQt application are copied verbatim from the Django application's views. As this is a game, I have already an engine.py module that I'm sharing among the two applications, but I was wondering how to restructure the middle layer (what in Django corresponds to the largest part of the views minus the return HttpResponse part) into its own component. In the web application the components are those of a classic Django application (with the only exception that I don't make any use of models): the game engine the url dispatcher the template the views My PyQt application is divided into: the game engine the UI definition where I declare the UI components and react to the events (basically this takes the place of the template and the url dispatcher in the Django app) the controller where I instantiate the window object and reproduce the methods that map the views in the Django app

• Single Responsibility Principle - How Can I Avoid Code Fragmentation?

  - by Dean Chalk

  I'm working on a team where the team leader is a virulent advocate of SOLID development principles. However, he lacks a lot of experience in getting complex software out of the door. We have a situation where he has applied SRP to what was already quite a complex code base, which has now become very highly fragmented and difficult to understand and debug. We now have a problem not only with code fragmentation, but also encapsulation, as methods within a class that may have been private or protected have been judged to represent a 'reason to change' and have been extracted to public or internal classes and interfaces which is not in keeping with the encapsulation goals of the application. We have some class constructors which take over 20 interface parameters, so our IoC registration and resolution is becoming a monster in its own right. I want to know if there is any 'refactor away from SRP' approach we could use to help fix some of these issues. I have read that it doesn't violate SOLID if I create a number of empty courser-grained classes that 'wrap' a number of closely related classes to provide a single-point of access to the sum of their functionality (i.e. mimicking a less overly SRP'd class implementation). Apart from that, I cannot think of a solution which will allow us to pragmatically continue with our development efforts, while keeping everyone happy. Any suggestions ?

• How to determine number of resources to be allocated in a software project

  - by aditi

  Last day I have been interviewed and the interviwer asked me as given the outline of a project, how can we determine the number of resources to be needed for the same? I donot know to do do so? Is there any standard way of doing so? or is it based on the experience? or how.... I am pretty new in this activity and my knowledge is zero at present .... so any clear explanation with some example(simple) will help me(and people like me) to understand this. Thanks

• How can you become a competent web application security expert without breaking the law?

  - by hal10001

  I find this to be equivalent to undercover police officers who join a gang, do drugs and break the law as a last resort in order to enforce it. To be a competent security expert, I feel hacking has to be a constant hands-on effort. Yet, that requires finding exploits, testing them on live applications, and being able to demonstrate those exploits with confidence. For those that consider themselves "experts" in Web application security, what did you do to learn the art without actually breaking the law? Or, is this the gray area that nobody likes to talk about because you have to bend the law to its limits?

• What C++ coding standard do you use?

  - by gablin

  For some time now, I've been unable to settle on a coding standard and use it concistently between projects. When starting a new project, I tend to change some things around (add a space there, remove a space there, add a line break there, an extra indent there, change naming conventions, etc.). So I figured that I might provide a piece of sample code, in C++, and ask you to rewrite it to fit your standard of coding. Inspiration is always good, I say. ^^ So here goes: #ifndef _DERIVED_CLASS_H__ #define _DERIVED_CLASS_H__ /** * This is an example file used for sampling code layout. * * @author Firstname Surname */ #include <stdio> #include <string> #include <list> #include "BaseClass.h" #include "Stuff.h" /** * The DerivedClass is completely useless. It represents uselessness in all its * entirety. */ class DerivedClass : public BaseClass { //////////////////////////////////////////////////////////// // CONSTRUCTORS / DESTRUCTORS //////////////////////////////////////////////////////////// public: /** * Constructs a useless object with default settings. * * @param value * Is never used. * @throws Exception * If something goes awry. */ DerivedClass (const int value) : uselessSize_ (0) {} /** * Constructs a copy of a given useless object. * * @param object * Object to copy. * @throws OutOfMemoryException * If necessary data cannot be allocated. */ ItemList (const DerivedClass& object) {} /** * Destroys this useless object. */ ~ItemList (); //////////////////////////////////////////////////////////// // PUBLIC METHODS //////////////////////////////////////////////////////////// public: /** * Clones a given useless object. * * @param object * Object to copy. * @return This useless object. */ DerivedClass& operator= (const DerivedClass& object) { stuff_ = object.stuff_; uselessSize_ = object.uselessSize_; } /** * Does absolutely nothing. * * @param useless * Pointer to useless data. */ void doNothing (const int* useless) { if (useless == NULL) { return; } else { int womba = *useless; switch (womba) { case 0: cout << "This is output 0"; break; case 1: cout << "This is output 1"; break; case 2: cout << "This is output 2"; break; default: cout << "This is default output"; break; } } } /** * Does even less. */ void doEvenLess () { int mySecret = getSecret (); int gather = 0; for (int i = 0; i < mySecret; i++) { gather += 2; } } //////////////////////////////////////////////////////////// // PRIVATE METHODS //////////////////////////////////////////////////////////// private: /** * Gets the secret value of this useless object. * * @return A secret value. */ int getSecret () const { if ((RANDOM == 42) && (stuff_.size() > 0) || (1000000000000000000 > 0) && true) { return 420; } else if (RANDOM == -1) { return ((5 * 2) + (4 - 1)) / 2; } int timer = 100; bool stopThisMadness = false; while (!stopThisMadness) { do { timer--; } while (timer > 0); stopThisMadness = true; } } //////////////////////////////////////////////////////////// // FIELDS //////////////////////////////////////////////////////////// private: /** * Don't know what this is used for. */ static const int RANDOM = 42; /** * List of lists of stuff. */ std::list <Stuff> stuff_; /** * Specifies the size of this object's uselessness. */ size_t uselessSize_; }; #endif

• Is it my responsibility to code for errors on a completely separate website and domain when redirecting or doing a single sign on?

  - by kappasims

  If my application is responsible for redirecting/doing a single sign on to a destination managed by a third party, in general, where should I draw the line for error handling during this process? If an error happens on the other application's end, is it reasonable for my stakeholder to expect the application I am working with to share responsibility for handling these scenarios? Notes: I am going to keep solutions limited to those that entail only one request--I am familiar with the "do an xmlhttprequest and see how that fares before doing anything else" approach. I am speaking in terms of an enterprise-level application with fairly decent customer traffic.

• Resources on how to relate structured and semi- / un-structured information

  - by Fritz Meissner

  I don't have a great background in information organisation / retrieval, but I know of a few ways of dealing with the problem. For structured information, it's possible to go OOish - everything "has-a" or "has-many" something else, and you navigate the graph to find relationships between things. For unstructured information, you have techniques like text search and tagging. What resources - articles or books - are there that summarise the CS theory behind these techniques or could introduce me to others? I'm developing a system that needs to handle capture and retrieval of information that ranges from necessarily unstructured (advice about X) to structured (list of Xs that relate to Ys) to a combination (Ys that relate to the advice about X) and I'd like to get some insight into how to do it properly.

• signal processing libraries

  - by khinester

  Are there any open source libraries/projects which work in a similar way to http://www.tagattitude.fr/en/products/technology? I am trying to understand the process. At first I thought this could work like when you send a fax to a fax machine. It is basically using the mobile phone’s microphone as a captor and its audio channel as a transporter. Are there any libraries for generating the signal and then being able to decode it?

• Using WebStorm for Razor Syntax MVC

  - by Jay Stevens

  I am building a lot of client-side heavy SPA-like apps with VS2010 and MVC3/4. VS2010 Javascript/HTML/CSS editing (mostly javascript) is interminably slow and sluggish. I'd love to use something like JetBrains' WebStorm to edit my .CSHTML files (with embedded javascript, etc. because I am using RAzor to pop in URL names, etc.) WebStorm seems to have all of the things I want.. better language recognition ("intellisense") and the ability to integrate additional outside libraries into this (I'm using Kendo), etc. Is this possible? How do you get WebStorm to recognize the @"" invoked Razor language inserts? Any help or suggestions would be appreciated.

• Generic Repository with SQLite and SQL Compact Databases

  - by Andrew Petersen

  I am creating a project that has a mobile app (Xamarin.Android) using a SQLite database and a WPF application (Code First Entity Framework 5) using a SQL Compact database. This project will even eventually have a SQL Server database as well. Because of this I am trying to create a generic repository, so that I can pass in the correct context depending on which application is making the request. The issue I ran into is my DataContext for the SQL Compact database inherits from DbContext and the SQLite database inherits from SQLiteConnection. What is the best way to make this generic, so that it doesn't matter what kind of database is on the back end? This is what I have tried so far on the SQL Compact side: public interface IRepository<TEntity> { TEntity Add(TEntity entity); } public class Repository<TEntity, TContext> : IRepository<TEntity>, IDisposable where TEntity : class where TContext : DbContext { private readonly TContext _context; public Repository(DbContext dbContext) { _context = dbContext as TContext; } public virtual TEntity Add(TEntity entity) { return _context.Set<TEntity>().Add(entity); } } And on the SQLite side: public class ElverDatabase : SQLiteConnection { static readonly object Locker = new object(); public ElverDatabase(string path) : base(path) { CreateTable<Ticket>(); } public int Add<T>(T item) where T : IBusinessEntity { lock (Locker) { return Insert(item); } } }

• Security Risks of Unsigned ClickOnce Manifests

  - by Tom Tom

  Using signed manifests in ClickOnce deployments, it is not possible to modify files after the deployment package has been published - installation will fail as hash information in the manifest won't match up with the modified files. I recently stumbled upon a situation where this was problematic - customers need to be able to set things like connection strings in app.config before deploying the software to their users. I got round the problem by un-checking the option to "Sign the ClickOnce manifests" in VS2010 and explicitly excluding the app.config file from the list of files to have hashes generated during the publish process. From a related page on MSDN "Unsigned manifests can simplify development and testing of your application. However, unsigned manifests introduce substantial security risks in a production environment. Only consider using unsigned manifests if your ClickOnce application runs on computers within an intranet that is completely isolated from the internet or other sources of malicious code." In my situation, this isn't an immediate problem - the deployment won't be internet-facing. However, I'm curious to learn what the "substantial security risks" of what I've done would be if it was internet-facing (or if things changed and it needed to be in the future). Thanks in advance!

• Big project layout : adding new feature on multiple sub-projects

  - by Shiplu

  I want to know how to manage a big project with many components with version control management system. In my current project there are 4 major parts. Web Server Admin console Platform. The web and server part uses 2 libraries that I wrote. In total there are 5 git repositories and 1 mercurial repository. The project build script is in Platform repository. It automates the whole building process. The problem is when I add a new feature that affects multiple components I have to create branch for each of the affected repo. Implement the feature. Merge it back. My gut feeling is "something is wrong". So should I create a single repo and put all the components there? I think branching will be easier in that case. Or I just do what I am doing right now. In that case how do I solve this problem of creating branch on each repository?

• Differences between TypeScript and Dart

  - by margabit

  Microsoft recently unveiled Typescript, a new JavaScript-like programming language. Some time ago, I heard about Dart, a new programming language created by Google to solve problems related to Javascript like performance, scalability, etc.. The purpose of both new languages seem the same to me.. What do you think? Are the purposes of the languages the same? What are the real differences about them?

• Should one generally develop a client library for REST services to help prevent API breakages?

  - by BestPractices

  We have a project where UI code will be developed by the same team but in a different language (Python/Django) from the services layer (REST/Java). The code for each layer exits in different code repositories and which can follow different release cycles. I'm trying to come up with a process that will prevent/reduce breaking changes in the services layer from the perspective of the UI layer. I've thought to write integration tests at the UI layer level that we'll run whenever we build the UI or the services layer (we're using Jenkins as our CI tool to build the code which is in two Git repos) and if there are failures then something in the services layer broke and the commit is not accepted. Would it also be a good idea (is it a best practice?) to have the developer of the services layer create and maintain a client library for the REST service that exists in the UI layer that they will update whenever there is a breaking change in their Service API? Conceivably, we would then have the advantage of a statically-typed API that the UI code builds against. If the client library API changes, then the UI code won't compile (so we'll know sooner that there was a breaking change). I'd also still run the integration tests upon building the UI or services layer to further validate that the integration between UI and the service(s) still works.

• Design Patterns: Should I learn them?

  - by prelic

  So it's kinda weird asking two questions back-to-back, but they aren't very related and I didn't want to combine them, but I'm not spamming questions, I promise! Anyway, I'm a recent college grad, and my education only touched on design patterns...we implemented a few simple ones, touched on the fact that there were more complicated ones, and were instructed to turn to the GoF book if we wanted to learn more. My question is, is it worth learning the patterns in the GoF book? To me, it's always seemed counter-intuitive to try and make a problem fit a classic pattern, but obviously the book, and the patterns, are famous for a reason. Do they show up enough that I should be learning them? Thanks again!

• B.S.in Computer Science, weak eyes => career change

  - by Prometheus

  So I am going to earn B.S. in Computer Science soon. I like computers. I like programming. The problem is that my eyes are very weak. Depending on their condition, I can only put in about 6 hours in front of computer a day. If I push myself, I have trouble even keeping my eyes open because of soreness/pain, consequently headaches. My eyes do not have medical conditions. I was just born with weak eyes. I tried many different approaches to work around this problem - better monitor, breaks every 10 minutes, supplements... I even memorized a lot of shortcuts to reduce my time on computers! But I am finally giving up. I do not think I can be a programmer for the rest of my life. I was the top of my class in high school because all works were paper-based, I did average in college due to the nature of my eyes and the difficulty of the material. So what do you recommend I do? Or, Is there a career that is similar to programming but requires interacting with computers less?
