• Good book for improving c# skills?

  - by JMarsch

  Hello: I was asked to recommend a good book for a mid-level experienced developer who wants to improve their coding skills (c# developer). I was thinking about: Code Complete: http://www.amazon.com/Code-Complete-Practical-Handbook-Construction/dp/0735619670/ref=sr_1_1?ie=UTF8&qid=1291221928&sr=8-1 The Pragmatic Programmer: http://www.amazon.com/Pragmatic-Programmer-Journeyman-Master/dp/020161622X/ref=sr_1_3?ie=UTF8&qid=1291221928&sr=8-3 or Effective C#: http://www.amazon.com/Effective-Covers-4-0-Specific-Development/dp/0321658701/ref=sr_1_1?s=books&ie=UTF8&qid=1291222038&sr=1-1 What do you think about those? Any other suggestions?

• Is there such a thing as having too many private functions/methods?

  - by shovonr

  I understand the importance of well documented code. But I also understand the importance of self-documenting code. The easier it is to visually read a particular function, the faster we can move on during software maintenance. With that said, I like to separate big functions into other smaller ones. But I do so to a point where a class can have upwards of five of them just to serve one public method. Now multiply five private methods by five public ones, and you get around twenty-five hidden methods that are probably going to be called only once by those public ones. Sure, it's now easier to read those public methods, but I can't help but think that having too many functions is bad practice.

• Customizing Texmaker

  - by Gabriel Furstenheim

  I use LaTeX a lot but I find quite obnoxious all the crappy files it leaves behind when you compile: .aux, .log... Fortunately TeXMaker has the option "clean" that deletes all of these. However, I don't like having to remember to click on it every time I'm going to close a document, ie I'd like a button that both closes a document and cleans all that stuff. Any hint as how to do it? I suppose if I knew how to access the program code I'd be able to do it as I'd just have to put together two options that already exist. Thanks

• Should Developers Perform All Tasks or Should They Specialize?

  - by Bob Horn

  Disclaimer: The intent of this question isn't to discern what is better for the individual developer, but for the system as a whole. I've worked in environments where small teams managed certain areas. For example, there would be a small team for every one of these functions: UI Framework code Business/application logic Database I've also worked on teams where the developers were responsible for all of these areas and more (QA, analsyt, etc...). My current environment promotes agile development (specifically scrum) and everyone has their hands in every area mentioned above. While there are pros and cons to each approach, I'd be curious to know if there are more pros and cons than I list below, and also what the generally feeling is about which approach is better. Devs Do It All Pros 1. Developers may be more well-rounded 2. Developers know more of the system Cons 1. Everyone has their hands in all areas, increasing the probability of creating less-than-optimal results in that area 2. It can take longer to do something with which you are unfamiliar (jack of all trades, master of none) Devs Specialize Pros 1. Developers can create policies and procedures for their area of expertise and more easily enforce them 2. Developers have more of a chance to become deeply knowledgeable about their specific area and make it the best it can be 3. Other developers don't cross boundaries and degrade another area Cons 1. As one colleague put it: "Why would you want to pigeon-hole yourself like that?" (Meaning some developers won't get a chance to work in certain areas.) It's easy to say how wonderful agile is, and that we should do it all, but I'm somewhat of a fan of having areas of expertise. Without that expertise, I've seen code degrade, database schemas become difficult to manage, hack UI code, etc... Let's face it, some people make careers out of doing just UI work, or just database work. It's not that easy to just fill in and do as good of a job as an expert in that area.

• Picking Core Language For Large Scale Web Platform

  - by ryanzec

  Now I have work with PHP and ASP.NET quite a bit and also played around few other language for web development. I am now at a point where need to start building a backend platform that will have the ability to support a large set of applications and I am trying to figure out which language I want to choose as my core language. When I say core language I mean the language that the majority of the backend code is going to be in. This is not to say that other languages won't be used because my guess is that they will but I want a large majority of the code (90%-98%) to be in 1 language. While I see to benefit of using the language that is best for the job, having 15% in php, 15% in ASP.NET, 5% in perl, 10% in python, 15% in ruby, etc… seems like a very bad idea to me (not to mention integrating everything seamlessly would probably add a bit of overhead). If you were going to be building a large scale web platform that need to support multiple applications from scratch, what would you choose as your core language and why?

• Looking for menu-driven coding platforms

  - by user2634047

  Can anyone point me to an application development environment that uses menu-driven coding? This would mean where commands, variable names, etc. are not keyed in, but rather are selected from a menu of context-specific options. For example, the user selects an If...then command from a menu of commands, and is then presented with a menu of variables to choose from for the the 'if' conditions(s) (or creates new variable(s) on the fly via the menu), and is then presented with a menu of applicable functions that are applicable to the selected variable (e.g., val()), and so on until the If...then statement has been fully coded. The idea is that the user never types any portion of the code, but selects all code elements from a menu, or defines them on the fly via the menu. Thanks.

• What Pattern will solve this - fetching dependent record from database

  - by tunmise fasipe

  I have these classes class Match { int MatchID, int TeamID, //used to reference Team ... other fields } Note: Match actually have 2 teams which means 2 TeamID class Team { int TeamID, string TeamName } In my view I need to display List<Match> showing the TeamName. So I added another field class Match { int MatchID, int TeamID, //used to reference Team ... other fields string TeamName; } I can now do Match m = getMatch(id); m.TeamName = getTeamName(m.TeamId); //get name from database But for a List<Match>, getTeamName(TeamId) will go to the database to fetch TeamName for each TeamID. For a page of 10 Matches per page, that could be (10x2Teams)=20 trip to database. To avoid this, I had the idea of loading everything once, store it in memory and only lookup the TeamName in memory. This made me have a rethink that what if the records are 5000 or more. What pattern is used to solve this and how?

• Develop a small size software using C only for copying same data to multiple external drives simultaneously [on hold]

  - by VSP

  I want to develop a software that can copy the same data to multiple external drives, simultaneously. For example, consider a file Movie and I have 3 external drives to copy it to, and I want to copy Movie to all these 3 drives(these drives can be flash storage or external hard-disk or pen-drive etc. but have one thing in common, i.e. they are all external drives) at the same time, means when I right-click on Movie there has to be 1 option saying Copy to All Drives. It's a sort of mini-project and I want to use C language only. For starting I would like it to work only on Windows OS. What are the requirements of developing this software (not the system requirements but what will I need to develop such a software, like editor,compiler etc.)? I know this type of software must have already been developed but I want to use C language and C Language only. So, is it possible to develop such a software?

• Which parallel pattern to use?

  - by Wim Van Houts

  I need to write a server application that fetches mails from different mail servers/mailboxes and then needs to process/analyze these mails. Traditionally, I would do this multi-threaded, launching a thread for fetching mails (or maybe one per mailbox) and then process the mails. We are moving more and more to servers where we have 8+ cores, so I would like to make use of these cores as much as possible (and not use 1 at 100% and leave the seven others untouched). So conceptually, as an example, it would be nice that I could write the application in such a way that two cores are "continuously" fetching emails and four cores are "continuously" processing/analyzing the emails (since processing and analyzing mails is more CPU intensive than fetching mails). This seems like a good concept, but after studying some parallel patterns, I'm not really sure how this is best implemented. None of the patterns really fit. I'm working in VS2012, native C++, but I guess from a design point of view this does not really matter and just some pointers on how to organize this would be great!

• Why job postings always looking for "rockstars?"

  - by Xepoch

  I have noticed a recent trend in requesting programmers who are rockstars. I get it, they're looking for someone who is really good at what they do. But why (pray) make the reference to a rockstar? Do these companies really want these traits as a real rockstar? Party all night and wake up to take care of quick business in the morning? Substance abuse, Narcissism with celebrity, Compensation well exceeding their management, Excellent at putting on a short-lived show, Entertainment instead of value, 1 hit (project) wonders or single-genre performers, Et cetera What is wrong with Senior or Principal Software Engineer who has an established and proven passion for the business? Rather do we mean quite the opposite, someone who: rolls up the sleeves and gets to work, takes appropriate direction and helps influence teams, programs in lessons' learned and proper practices, provides timely communication to the whole team, can code and understand multiple languages, understands the science and theory behind computation, Is there a trend to diversify the software engineering ranks? How many software rockstars can you hire before your band starts breaking up? Sure, there are lots of folks doing this stuff on their own, maybe even a rare few who do coding for show, but I wager the majority is for business. I don't see ads for rockstar accountants, or rockstar machinists, or rockstart CFOs. What makes the software programmer and their hiring departments lean towards this kind of job title?

• FP for simulation and modelling

  - by heaptobesquare

  I'm about to start a simulation/modelling project. I already know that OOP is used for this kind of projects. However, studying Haskell made me consider using the FP paradigm for modelling a system of components. Let me elaborate: Let's say I have a component of type A, characterised by a set of data (a parameter like temperature or pressure,a PDE and some boundary conditions,etc.) and a component of type B, characterised by a different set of data(different or same parameter, different PDE and boundary conditions). Let's also assume that the functions/methods that are going to be applied on each component are the same (a Galerkin method for example). If I were to use an OOP approach, I would create two objects that would encapsulate each type's data, the methods for solving the PDE(inheritance would be used here for code reuse) and the solution to the PDE. On the other hand, if I were to use an FP approach, each component would be broken down to data parts and the functions that would act upon the data in order to get the solution for the PDE. This approach seems simpler to me assuming that linear operations on data would be trivial and that the parameters are constant. What if the parameters are not constant(for example, temperature increases suddenly and therefore cannot be immutable)? In OOP, the object's (mutable) state can be used. I know that Haskell has Monads for that. To conclude, would implementing the FP approach be actually simpler,less time consuming and easier to manage (add a different type of component or new method to solve the pde) compared to the OOP one? I come from a C++/Fortran background, plus I'm not a professional programmer, so correct me on anything that I've got wrong.

• How Is there anyway to Compile Notepad++?

  - by user44179

  I really like using Notepad++ to write HTML and such. After I started using Ubuntu I looked around for an alternative to Notpad++. I found a thread which lead me to try Geany and a few others, but I really miss Notepad++. Is there anyway I could compile it from the source code to use on Ubuntu? I know its written in C++. Could I just open it in Code::Blocks and compile it? You can get the source here. I wouldn't mind hearing about other alternatives, but really want to know if compiling it is possible. Thanks

• Single responsibility principle - am I overusing it?

  - by Tarun

  For reference - http://en.wikipedia.org/wiki/Single_responsibility_principle I have a test scenario where in one module of application is responsible for creating ledger entries. There are three basic tasks which could be carried out - View existing ledger entries in table format. Create new ledger entry using create button. Click on a ledger entry in the table (mentioned in first pointer) and view its details in next page. You could nullify a ledger entry in this page. (There are couple more operation/validations in each page but fore sake of brevity I will limit it to these) So I decided to create three different classes - LedgerLandingPage CreateNewLedgerEntryPage ViewLedgerEntryPage These classes offer the services which could be carried out in those pages and Selenium tests use these classes to bring application to a state where I could make certain assertion. When I was having it reviewed with on of my colleague then he was over whelmed and asked me to make one single class for all. Though I yet feel my design is much clean I am doubtful if I am overusing Single Responsibility principle

• Is perfectionism a newbie's friend or enemy? [closed]

  - by Akromyk

  Possible Duplicate: Where do you draw the line for your perfectionism? I see that the development community is very focused on doing things the right way and personally I would like to do the same too, however, is it a good or bad idea for a newbie to focus on design principles, design patterns, and commenting code when getting started, or is it better to let creativity run wild and potentially write sloppy code. Where should a newbie draw the line?

• Attributes of an Ethical Programmer?

  - by ahmed

  Software that we write has ramifications in the real world. If not, it wouldn't be very useful. Thus, it has the potential to sweep across the world faster than a deadly manmade virus or to affect society every bit as much as genetic manipulation. Maybe we can't see how right now, but in the future our code will have ever-greater potential for harm or good. Of course, there's the issue of hacking. That's clearly a crime. Or is it that clear? Isn't hacking acceptable for our government in the event of national security? What about for other governments? Cases of life-and-death emergency? Tracking down deadbeat parents? Screening the genetic profile of job candidates? Where is the line drawn? Who decides? Do programmers have responsibility for how their code is used? What if a programmer writes code to pry into confidential information or copy-protected material? Does he bear responsibility along with the person who used the program? What about a programmer who knowingly or unknowingly writes code to "fix the books?" Should he be liable?

• How to write comments to explain the "why" behind the callback function when the function and parameter names are insufficient for that?

  - by snowmantw

  How should I approach writing comments for callback functions? I want to explain the "why" behind the function when the function and parameter names are insufficient to explain what's going on. I have always wonder why comments like this can be so ordinary in documents of libraries in dynamic languages: /** * cb: callback // where's the arguments & effects? */ func foo( cb ) Maybe the common attitude is "you can look into source code on your own after all" which pushes people into leaving minimalist comments like this. But it seems like there should be a better way to comment callback functions. I've tried to comment callbacks in Haskell way: /** * cb: Int -> Char */ func foo(cb) And to be fair, it's usually neat enough. But it gets into trouble when I need to pass some complex structure. The problem being partly due to the lack of type system: /** * cb: Int -> { err: String -> (), success: () -> Char } // too long... */ func foo(cb) Or I have tried this too: /** * cb: Int -> { err: String -> (), * success: () -> Char } // better ? */ func bar(cb) The problem is that you may put the structure in somewhere else, but you must give it a name to reference it. But then when you name a structure you're about to use immediately looks so redundant: // Somewhere else... // ResultCallback: { err: String -> (), success: () -> Char } /** * cb: Int -> ResultCallback // better ?? */ func foo(cb) And it bothers me if I follow the Java-doc like commenting style since it still seems incomplete. The comments don't tell you anything that you couldn't immediately see from looking at the function. /** * @param cb {Function} yeah, it's a function, but you told me nothing about it... * @param err {Function} where should I put this callback's argument ?? * Not to mention the err's own arguments... */ func foo(cb) These examples are JavaScript like with generic functions and parameter names, but I've encountered similar problems in other dynamic languages which allow complex callbacks.

• returning null vs returning zero, which would be better?

  - by Dark Star1

  I inherited a project that I am managing and having to maintain pending the redevelopment of the code base. At the moment I am being tasked with adding little feature all over the place and have gotten into the habit of returning null instead of zero in parts of the code where I am working on. The problem is we have a client that is using this code and parts of code that require data from my implemented features recieve a null and dump the stack trace in UI. I would like to avoid this entirely from my input but without the nullPointer exceptions there's the potential that errors would be introduced into the client's data which may go un-noticed. Usually I would have come up with my own error notification system but I have never inherited a project before. so I am unsure whether to continue down this path. I still believe that the stack dump is preferable to un-noticed data corruption/inaccuracies.

• Draw contour around object in Opengl

  - by Maciekp

  I need to draw contour around 2d objects in 3d space. I tried drawing lines around object(+points to fill the gap), but due to line width, some part of it(~50%) was covering object. I tried to use stencil buffer, to eliminate this problem, but I got sth like this(contour is green): http://goo.gl/OI5uc (sorry I can't post images, due to my reputation) You can see(where arrow points), that some parts of line are behind object, and some are above. This changes when I move camera, but always there is some part, that is covering it. Here is code, that I use for drawing object: glColorMask(1,1,1,1); std::list<CObjectOnScene*>::iterator objIter=ptr->objects.begin(),objEnd=ptr->objects.end(); int countStencilBit=1; while(objIter!=objEnd) { glColorMask(1,1,1,1); glStencilFunc(GL_ALWAYS,countStencilBit,countStencilBit); glStencilOp(GL_REPLACE,GL_KEEP,GL_REPLACE ); (*objIter)->DrawYourVertices(); glStencilFunc(GL_NOTEQUAL,countStencilBit,countStencilBit); glStencilOp(GL_KEEP,GL_KEEP,GL_REPLACE); (*objIter)->DrawYourBorder(); ++objIter; ++countStencilBit; } I've tried different settings of stencil buffer, but always I was getting sth like that. Here is question: 1.Am I setting stencil buffer wrong? 2. Are there any other simple ways to create contour on such objects? Thanks in advance.

• Is this high coupling?

  - by Bono

  Question I'm currently working a on an assignment for school. The assignment is to create a puzzle/calculator program in which you learn how to work with different datastructures (such as Stacks). We have generate infix math strings suchs as "1 + 2 * 3 - 4" and then turn them in to postfix math strings such as "1 2 + 3 * 4 -". In my book the author creates a special class for converting the infix notation to postfix. I was planning on using this but whilst I was about to implement it I was wondering if the following is what you would call "high coupling". I have read something about this (nothing that is taught in the book or anything) and was wondering about the aspect (since I still have to grasp it). Problem I have created a PuzzleGenerator class which generates the infix notation of the puzzle (or math string, whatever you want to call it) when it's instantiated. I was going to make a method getAnswer() in which I would instantiate the InToPost class (the class from the book) to convert the infix to postfox notation and then calculate the answer. But whilst doing this I thought: "Is using the InToPost class inside this method a form a high coupling, and would it be better to place this in a different method?" (such as a "convertPostfixToInfix" method, inside the PuzzleGenerator class) Thanks in advance.

• How to deal with elimination of duplicate logic vs. cost of complexity increase?

  - by Gabriel

  I just wrote some code that is very representative of a recurring theme (in my coding world lately): repeated logic leads to an instinct to eliminate duplication which results in something that is more complex the tradeoff seems wrong to me (the examples of the negative side aren't worth posting - but this is probably the 20th console utility I've written in the past 12 months). I'm curious if I'm missing some techniques or if this is really just on of those "experience tells you when to do what" type of issues. Here's the code... I'm tempted to leave it as is, even though there will be about 20 of those if-blocks when I'm done. static void Main(string[] sargs) { try { var urls = new DirectTrackRestUrls(); var restCall = new DirectTrackRestCall(); var logger = new ConsoleLogger(); Args args = (Args)Enum.Parse(typeof(Args), string.Join(",", sargs)); if (args.HasFlag(Args.Campaigns)) { var getter = new ResourceGetter(logger, urls.ListAdvertisers, restCall); restCall.UriVariables.Add("access_id", 1); getter.GotResource += new ResourceGetter.GotResourceEventHandler(getter_GotResource); getter.GetResources(); SaveResources(); } if (args.HasFlag(Args.Advertisers)) { var getter = new ResourceGetter(logger, urls.ListAdvertisers, restCall); restCall.UriVariables.Add("access_id", 1); getter.GotResource += new ResourceGetter.GotResourceEventHandler(getter_GotResource); getter.GetResources(); SaveResources(); } if (args.HasFlag(Args.CampaignGroups)) { var getter = new ResourceGetter(logger, urls.ListCampaignGroups, restCall); getter.GotResource += new ResourceGetter.GotResourceEventHandler(getter_GotResource); getter.GetResources(); SaveResources(); } } catch (Exception e) { Console.WriteLine(e.InnerException); Console.WriteLine(e.StackTrace); }

• How can I create an orthographic display that handles different screen dimensions?

  - by Piku

  I'm trying to create an iPad/iPhone game using GLES2.0 that contains a 3D scene with a heads-up-display/GUI overlaid on the top. However, this problem would also apply if I were to port my game to a computer and run the game in a resizable window, or allow the user to change screen resolutions... When trying to make the 2D GUI/HUD work I've made the assumption that all I'm really doing is drawing a load of 2D textured 'quads' on the screen and am trying to treat the orthographic projection as an old-style 2D display with 0,0 in the upper left and screenWidth,ScreenHeight in the lower right. This causes me all sorts of confusion when I rotate my ipad into Landscape mode since I can't work out what to put into my projection and modelview matrices to turn everything around the right way. It also gets messy if I want to support the iPad's large screen, an iPhone or a Retina display since I have to then draw three sets of textures for everything and work out which ones to use. Should I be trying to map the 2D OpenGL co-ords 1:1 with the screen? While typing out this question it occurs to me that I could keep my origin in the centre, still running -1/+1 along the axes. This would let me scale my 2D content appropriately on the different screen sizes, but wouldn't I end up with the textures being scaled and possibly losing quality? I'm using OpenGLES 2.0 and have a matrix library that has equivalents to the GLES1.1 glOrthof() and glFrustrum() calls.

• Entry level engineer question regarding memory mangement

  - by Ealianis

  It has been a few months since I started my position as an entry level software developer. Now that I am past some learning curves (e.g. the language, jargon, syntax of VB and C#) I'm starting to focus on more esoteric topics, as to write better software. A simple question I presented to a fellow coworker was responded with "I'm focusing on the wrong things." While I respect this coworker I do disagree that this is a "wrong thing" to focus upon. Here was the code (in VB) and followed by the question. Note: The Function GenerateAlert() returns an integer. Dim alertID as Integer = GenerateAlert() _errorDictionary.Add(argErrorID, NewErrorInfo(Now(), alertID)) vs... _errorDictionary.Add(argErrorID, New ErrorInfo(Now(), GenerateAlert())) I originally wrote the ladder and rewrote it with the "Dim alertID" so that someone else might find it easier to read. But here was my concern and question. "Should one write this with the Dim AlertID, it would in fact take up more memory; finite but more, and should this method be called many times could it lead to an issue? How will .NET handle this object AlertID. Outside of .NET should one manually dispose of the object after use (near the end of the sub)." I want to ensure I become a knowledgeable programmer that does not just rely upon garbage collection. Am I over thinking this? Am I focusing on the wrong things?
