• Should "closed as duplicate" software programming be extreme or functional? [migrated]

  - by Web Developer

  I'm a web developer loving this site for it's potential, and it's Coffee look . I was reading a great question, that is this: click here and noticed 8 moderators tagged it as DUPLICATED! The question was closed! Obviously it isn't and I'm going to explain why if needed but it can be seen: the question is unique, is the case/story of a young who have SPECIFIC experience with C++ , VB and Assembler and asking, knowing this specifications an answer (It is not a general question like "hey I'm young can I do the programmer??") Let me know your opinion! do you think this question should or should not be closed? And let's think about also the people not only the "data" and "cases covered" ... do you think this is important too? or is better to keep a place where people doesn't count?

• Web Service - SOAP

  - by seth

  My experience with web services is slim and I'm trying to understand this a little bit more. I have done for instance a web service using visual studio. In order to use it, I add a web service reference in my projects and this creates a proxy and the use is pretty simple. Does this use SOAP? I ask this because i will be now facing a web service that i must communicate using SOAP with attachements and i'm trying to understand the concept behind this and the difference to what i have done so far. Will the proxy still be viable or do i need to create the XML by hand and post it to the web service? This concepts still confuse and so any help is appreciated. EDIT: I'm not developing the service, i will be just using it.

• 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

• How to write reusable code in node.js

  - by lortabac

  I am trying to understand how to design node.js applications, but it seems there is something I can't grasp about asynchronous programming. Let's say my application needs to access a database. In a synchronous environment I would implement a data access class with a read() method, returning an associative array. In node.js, because code is executed asynchronously, this method can't return a value, so, after execution, it will have to "do" something as a side effect. It will then contain some code which does something else than just reading data. Let's suppose I want to call this method multiple times, each time with a different success callback. Since the callback is included in the method itself, I can't find a clean way to do this without either duplicating the method or specifying all possible callbacks in a long switch statement. What is the proper way to handle this problem? Am I approaching it the wrong way?

• How to handle people who lie on their resume [closed]

  - by Juliet

  Moderator comment Please note that this is a two year old question that has just been migrated from Stack Overflow. Please take your time to read all the answers and ask yourself "would my answer add anything to this?". I'm conducting technical interviews to fill a few .NET positions. Many of the people I interview really do know .NET pretty well, but I find at least 90% embellish their skillset anywhere between "a little" to "quite drastically". Sometimes they fabricate skills relevant to the position they're applying for, sometimes they don't. Most of the people I interview, even the most egregious liars, are not scam artists. They just want to stand out among the crowd, so they drop a few buzzwords on their resume like "JBoss", "LINQ", "web services", "Django" or whatever just to pad their skillset and stay competitive. (You might wonder if a person that lies about those skills is just bluffing their way through a technical interview. My interviews involve a lot of hands-on coding and problem-solving – people who attempt to bluff will bomb the hands-on coding portion in the first 3 minutes.) These are two open-ended questions, but it would really help me out when I make my recommendations to the hiring managers: Regarding interviewing etiquette, should I attempt to determine whether a person really possesses all of the skills they claim to have? Can I do this without making the candidate feel uncomfortable? Regarding the final decision, should I recommend candidates who are genuinely qualified for the positions they're applying for, even if they've fabricated portions of their skillset?

• Fastest way to get up to speed on webapp development with ASP.NET?

  - by leeand00

  I'm trying to get better at C# ASP.NET 3.5 development (...no none of that MVC stuff :), and fast! My boss gave me a book to read on it from Wrox, but the thing reads like a history novel, telling you how things worked as far back as ASP.NET 1.0; The web application we are developing is completely in ASP.NET 3.5 so I don't need to read through any of the history (maybe I'm wrong about that...but I don't really have the time to read about that...) Do you have any suggestions for a faster (book, series of tutorials) to come up to speed on it? I'd like to learn about UI components, database access, etc... P.S. In a previous position I was an JSP/J2EE developer (and I used MVC all the time! :-D) P.S.S. I did take a course on it in 2008 at some point, but it seemed all very pointy and clickly. I wanna learn the code stuff! The how it works, and where the events are!

• Ways of Gathering Event Information From the Internet

  - by Ciwan

  What are the best ways of gathering information on events (any type) from the internet ? Keeping in mind that different websites will present information in different ways. I was thinking 'smart' web crawlers, but that can turn out to be extremely challenging, simply because of the hugely varied ways that different sites present their information. Then I was thinking of sifting through the official twitter feeds of organisations, people with knowledge of events .. etc and look for the event hash tag, grab the tweet and dissect it to grab the relevant information about the event. Information I am interested in gathering is: Date and Time of Event, Address where Event is being held, and any Celebrities (or any famous people) attending the event (if any). The reason to ask here is my hope that experienced folk will open my eyes to things I've missed, which I am sure I have.

• What's the best practice for async APIs that return futures on Scala?

  - by Maurício Linhares

  I have started a project to write an async PostgreSQL driver on Scala and to be async, I need to accept callbacks and use futures, but then accepting a callback and a future makes the code cumbersome because you always have to send a callback even if it is useless. Here's a test: "insert a row in the database" in { withHandler { (handler, future) => future.get(5, TimeUnit.SECONDS) handler.sendQuery( this.create ){ query => }.get( 5, TimeUnit.SECONDS ) handler.sendQuery( this.insert ){ query => }.get( 5, TimeUnit.SECONDS ).rowsAffected === 1 } } Sending the empty callback is horrible but I couldn't find a way to make it optional or anything like that, so right now I don't have a lot of ideas on how this external API should look like. It could be something like: handler.sendQuery( this.create ).addListener { query => println(query) } But then again, I'm not sure how people are organizing API's in this regard. Providing examples in other projects would also be great.

• Executing Shell Commands - PHP or Python?

  - by chadpeppers

  I know basically two languages: Python and PHP. I am primarily a Drupal developer. I have a great idea in creating a command line program that will help some of the mundane tasks and bring my efficiency up quite a bit. The concept is that of a complete console program, almost like the days when I learned C++ using stdin/out. I want to use this came concept but for this program. I am going to be executing shell commands (mainly drush commands, if you are familiar with drush its drupals way of doing tasks like installing drupal, clearing cache, and other things). I am also wanting to do a database and save/execute through multiple objects and site profiles. My general question is this. Which language would be better suited to handle command line code? Drupal is written in PHP so I am leaned more towards that,but I know python seems to handle console programming a bit easier. Any help would be great!

• Is the C programming language still used?

  - by Pankaj Upadhyay

  I am a C# programmer, and most of my development is for websites along with a few Windows application. As far as C goes, I haven't used it in a long time, as there was no need to. It came to me as a surprise when one of my friends said that she needs to learn C for testing jobs, while I was helping her learn C#. I figured that someone would only learn C for testing only if there is development done in C. In my knowledge, all the development related to COM and hardware design are also done in C++. Therefore, learning C doesn't make sense if you need to use C++. I also don't believe in historic significance, so why waste time and money in learning C? Is C is still used in any kind of new software development or anything else?

• Which iPhone ad API has produced the highest revenue for you?

  - by Kyle Humfeld

  This isn't a technical question, but more of a request for advice and empirical/anecdotal data. I'm nearly done writing a free app for iPhone, and I'm at the stage where I'm going to put ads into the app. I've had mixed success in the past with iAd (their fill rates have been atrocious recently, and their payouts have cut by about 75% over the past 4 months or so), and would like to know how much ad revenue you, the community, has seen from the various ad APIs you've used for your iPhone apps. This isn't a request for opinion, i.e. which is 'better', only what kinds of numbers you're seeing. I don't need absolute figures, but 'iAd pays x% higher than AdMob, and y% lower than AdSense' would be extremely helpful to me as I make my decision as to which ad API to integrate into my App. Also, have you had any experience or success with integrating multiple ad APIs into the same app? That's something I'm considering doing in my current iAd-filled apps (particularly my iPad app, which has yet to receive a single impression after nearly 60,000 requests)... something like: 1) Request-from-iAd 2) if that fails, request-from-adSense 3) if that fails, request-from-adMob 4) if that fails, ... etc.

• How does TDD address interaction between objects?

  - by Gigi

  TDD proponents claim that it results in better design and decoupled objects. I can understand that writing tests first enforces the use of things like dependency injection, resulting in loosely coupled objects. However, TDD is based on unit tests - which test individual methods and not the integration between objects. And yet, TDD expects design to evolve from the tests themselves. So how can TDD possibly result in a better design at the integration (i.e. inter-object) level when the granularity it addresses is finer than that (individual methods)?

• Leadership does not see value in standard process for machine configuration and new developer orientation

  - by opensourcechris

  About 3 months ago our lead web developer and designer(same person) left the company, greener pastures was the reason for leaving. Good for them I say. My problem is that his department was completely undocumented. Things have been tough since the lead left, there is a lot of knowledge both theoretical knowledge we use to quote new projects and technical/implementation knowledge of our existing products that we have lost as a result of his departure. My normal role is as a product manager (for our products themselves) and as a business analyst for some of our project based consulting work. I've taught myself to code over the past year and in an effort to continue moving forward I've taken on the task of setting my laptop up as a development machine with hopes of implementing some of the easier feature requests and fixing some of the no brainer bugs that get submitted into our ticketing system. But, no one knows how to take a fresh Windows machine and configure it to work seamlessly with our production apps. I have requested my boss, who is still in contact with the developer who left, ask them to document and create a process to onboard a new developer, software installation, required packages, process to deploy to the productions application servers, etc. None of this exists, and I'm spinning my wheels trying to get my computer working as a functional development machine. But she does not seem to understand the need for such a process to exist. Apparently the new developer who replaced the one who left has been using a machine that was pre-configured for our environment, so even the new developer could not set up a new machine if we added another developer. My question is two part: Am I wrong in assuming a process to on-board and configure a new computer to be part of our development eco-system should exist? Am I being a whinny baby and should I figure the process out and create a document on my own?

• Am I too young to burn out?

  - by Steve McMesse

  I feel like I have burned out, even though I am only out of college for 5 years. For the first 3 years of my career, things were going awesome. I was never anything special in school, but I felt special at my company. Looking back, I could tell that I made all the right moves: I actively tried to improve myself daily. I made a point of helping anyone I could. I made a point (and read books about) being a good team member. I had fun. After 3 years in a row as being rated as a top employee, I converted that political capital into choosing to work on an interesting, glamorous project with only 2 developers: me and a highly respected senior technical leader. I worked HARD on that project, and it came out a huge success. High in quality, low in bugs, no delays, etc. The senior tech lead got a major promotion and a GIGANTIC bonus. I got nothing. I was so disappointed that I just stopped caring. Over the last year, I have just kind of floated. During my first 4 years I felt energized after a 10 hour day. Now I can barely be bothered to work 6 hours a day. Any advice? I don't even know what I'm asking. I am just hoping smart people see this and drop me a few pieces of wisdom.

• creating a google wave clone using php/mysql/jquery

  - by jeansymolanza

  seasons greetings to all. i have a question that has been rather bugging me as of late. does anyone know how one can create a google wave clone using php/mysql/jquery as primary points of development. any ideas on how this might be possible and recommend any starting points? i have some time off work and it would be an interesting project to undertake as i want to use it in an e-learning framework next year. i will be testing the product on a XAMPP local server. i understand some of the technologies that google wave using but i am rather curious as to how these can be developed to a decent standard using php/mysql/jquery (i mention these three because i am quite adept at them). any links to resources best suited to an intermediate programmer would be appreciated. many thanks and God bless. so far i have this: http://konrness.com/javascript/google-wave-style-scroll-bar-jquery-plugin/

• alternative to environment variables

  - by tonyl7126

  The amount of servers and the complexity of our application is growing and we now have servers in different regions (hosted on AWS). Certain database operations require low latency so we have stuck a database in each region (which is basically a user cache) to keep the network latency low. The way the application server currently knows which user cache/database to make its call to depends on an environemnt variable set in it. This has been working fine, but it seems hacky and not optimal. Is there any way for this to be done automatically? I was considering using a package like fping and pinging each database when the app server reloads (or caching it the first time) and using the corresponding latencies to decide which database has the lowest latency for each app server. Not sure if this is the best idea though.

• One page using querystring or many folders and pages?

  - by ClarkeyBoy

  I have an application where I have the 'core' code in one folder for which there is a virtual directory in the root, such that I can include any core files using /myApp/core/bla.asp. I then have two folders outside of this with a default.asp which currently use the querystring to define what page should be displayed. One page is for general users, the other will only be accessible to users who have permission to manage users / usergroups / permissions. The core code checks the querystring and then checks the permissions for that user. An example of this as it is now is default.asp?action=view&viewtype=list&objectid=server. I am not worried about SEO as this is an internal app and uses Windows Auth. My question is, is it better the way it is now or would it be better to have something like the following: /server/view/list/ /server/view/?id=123 /server/create/ /server/edit/?id=123 /server/remove/?id=123 In the above folders I would have a home page which defines all the variables which are currently determined by the querystring - in /server/create/ for example, I would define the action as 'create', object name as 'server' and so on. In terms of future development, I really have no idea which method would be best. I think the 2nd method would be best in terms of following what page does what but this is such a huge change to make at this stage that I would really like some opinions, preferably based on experience. PS Sorry if the tags are wrong - I am new to this forum and thought this was a bit too much of a discussion for StackOverflow as that is very much right / wrong answer based. I got the idea SE is more discussion based.

• Using branchs for a mini project or module of project: Good practice?

  - by TheLQ

  In my repo I have 3 closely related mini projects: 1 server and 2 clients. They are all quite small (<3 files each). Since they are so small and so closely related I just dropped them in folders in one single repo. However now that I know I can't clone a single directory in my VCS of choice (Mercurial), I'm considering splitting them up. However I'm confused about general best practice: Is it okay to put different small projects in different branches, or should they all go in different repos? I'm currently leaning towards branching since I can't easily splice out the file history of the different projects but then your using a feature in a way it wasn't meant to be used.

• agile as our first project management methodology [closed]

  - by Hasan Khan

  we are a small web development company that has till now been working on client projects. we employed little to no project management and that has cost us a lot. we've used only the barest of tools (wireframing, prototyping etc) but no formal project management process has been put into place. we've learnt from our mistakes and want to prevent them from happening in the future. also, we are looking to develop our own products and we understand that putting in a proper project management paradigm will help. after a lot of research, we've sort of settled on agile for a few reasons: agile seems to scale well with team size. our team is small right now and we hope to grow and agile seems to be a process that we can put in place now and grow with. agile will help us with customers who just can't seem to make up their minds and keep changing requirements. we'd appreciate the community's thoughts on this. is this a correct way to think? will agile be a good system to put into place, where there has been none till now? are there any resources that may help us in our position? pretty much all of the resources that we've found start by comparing agile to x (where x = any management methodology) and why its better than x and how agile can be implemented in place of x. we're looking for resources that can help us out in our particular situation. thanks for all your help!

• Variable naming conventions?

  - by Ziv

  I've just started using ReSharper (for C#) and I kind of like its code smells finder, it shows me some things about my writing that I meant to fix a long time ago (mainly variable naming conventions). It caused me to reconsider some of my naming conventions for methods and instance variables. ReSharper suggests that instance variable be lower camel case and begin with an underscore. For a while I meant to make all my local variables lower camel case but is the underscore necessary? Do you find it comfortable? I don't like this convention but I also haven't tried it yet, what is you opinion of it? The second thing it prompted me to re-evaluate is my naming conventions for GUI event handlers. I usually use the VS standard of ControlName_Action and my controls usually use hungarian notation (as a suffix, to help clarify in code what is visible to the user and what isn't when dealing with similarly named variable) so I end up with OK_btn_Click(), what is your opinion of that? Should I succumb to the ReSharper convention or there are other equally valid options?

• What encoding is used by javax.xml.transform.Transformer?

  - by Simon Reeves

  Please can you answer a couple of questions based on the code below (excludes the try/catch blocks), which transforms input XML and XSL files into an output XSL-FO file: File xslFile = new File("inXslFile.xsl"); File xmlFile = new File("sourceXmlFile.xml"); TransformerFactory tFactory = TransformerFactory.newInstance(); Transformer transformer = tFactory.newTransformer(new StreamSource(xslFile)); FileOutputStream fos = new FileOutputStream(new File("outFoFile.fo"); transformer.transform(new StreamSource(xmlFile), new StreamResult(fos)); inXslFile is encoded using UTF-8 - however there are no tags in file which states this. sourceXmlFile is UTF-8 encoded and there may be a metatag at start of file indicating this. am currently using Java 6 with intention of upgrading in the future. What encoding is used when reading the xslFile? What encoding is used when reading the xmlFile? What encoding will be applied to the FO outfile? How can I obtain the info (properties) for 1 - 3? Is there a method call? How can the properties in 4 be altered - using configuration and dynamically? if known - Where is there info (web site) on this that I can read - I have looked without much success.

• How do developers verify that software requirement changes in one system do not violate a requirement of downstream software systems?

  - by Peter Smith

  In my work, I do requirements gathering, analysis and design of business solutions in addition to coding. There are multiple software systems and packages, and developers are expected to work on any of them, instead of being assigned to make changes to only 1 system or just a few systems. How developers ensure they have captured all of the necessary requirements and resolved any conflicting requirements? An example of this type of scenario: Bob the developer is asked to modify the problem ticket system for a hypothetical utility repair business. They contract with a local utility company to provide this service. The old system provides a mechanism for an external customer to create a ticket indicating a problem with utility service at a particular address. There is a scheduling system and an invoicing system that is dependent on this data. Bob's new project is to modify the ticket placement system to allow for multiple addresses to entered by a landlord or other end customer with multiple properties. The invoicing system bills per ticket, but should be modified to bill per address. What practices would help Bob discover that the invoicing system needs to be changed as well? How might Bob discover what other systems in his company might need to be changed in order to support the new changes\business model? Let's say there is a documented specification for each system involved, but there are many systems and Bob is not familiar with all of them. End of example. We're often in this scenario, and we do have design reviews but management places ultimate responsibility for any defects (business process or software process) on the developer who is doing the design and the work. Some organizations seem to be better at this than others. How do they manage to detect and solve conflicting or incomplete requirements across software systems? We currently have a lot of tribal knowledge and just a few developers who understand the entire business and software chain. This seems highly ineffective and leads to problems at the requirements level.
