• Web Developer or Software Engineer?

  - by dahacker89

  A question that I have been asking myself and really confused which path to take. So I need your guys help as to the pros and cons of these 2 professions in today's world. I love web applications development as the Web is the best thing to happen in this age and nearly everyone gets by on the World Wide Web. And also tend to keep learning about new technologies and about web services. On the other hand I like software engineering also for the desktop applications as I have had experience with development small scale softwares in VB.Net, Java, C++, etc. Which path has more scope and better future? Whats your view?

• Additional useful skill?

  - by Sergey

  Almost each language has some additional technology or skill or whatever which can work in a pair with it but still be something fresh. For example, Java + Flex. It's a good pair - those who learn Java and want something both useful and new may try Flex. What are "pairs" for the most popular languages(Java, C#, C++, etc.)? PS: Most people advise learning functional programming as an additional skill but this is very fuzzy. They talk about such abstract things as wide programming perspective and other things, but you can hardly say whether these functional skills will be really needed. Yeah, maybe some basics of it can be useful, but serious learning of LISP seems not perspective.

• Stack Trace Logger [migrated]

  - by Chris Okyen

  I need to write a parent Java class that classes using recursion can extend. The parent class will be be able to realize whenever the call stack changes ( you enter a method, temporarily leave it to go to another method call, or you are are finsihed with the method ) and then print it out. I want it to print on the console, but clear the console as well every time so it shows the stack horizantaly so you can see the height of each stack to see what popped off and what popped on... Also print out if a baseline was reached for recursive functions. First. How can I using the StackTraceElements and Thread classes to detect automatically whenever the stack has popped or pushed an element on without calling it manually? Second, how would I do the clearing thing? For instance , if I had the code: public class recursion(int i) { private static void recursion(int i) { if( i < 10) System.out.println('A'); else { recursion(i / 10 ); System.out.println('B'); } } public static void main(String[] argv) { recursion(102); } } It would need to print out the stack when entering main(), when entering recursion(102) from main(), when it enters recursion(102 / 10), which is recursion(10), from recursion(102), when it enters recursion(10 / 10), which is recursion(1) from recursion(10). Print out a message out when it reaches the baseline recursion(1).. then print out the stacks of reversed revisitation of function recursion(10), recursion(102) and main(). finally print out we are exiting main().

• Web Application: Combining View Layer Between PHP and Javascript-AJAX

  - by wlz

  I'm developing web application using PHP with CodeIgniter MVC framework with a huge real time client-side functionality needs. This is my first time to build large scale of client-side app. So I combine the PHP with a large scale of Javascript modules in one project. As you already know, MVC framework seperate application modules into Model-View-Controller. My concern is about View layer. I could be display the data on the DOM by PHP built-in script tag by load some data on the Controller. Otherwise I could use AJAX to pulled the data -- treat the Controller like a service only -- and display the them by Javascript. Here is some visualization I could put the data directly from Controller: <label>Username</label> <input type="text" id="username" value="<?=$userData['username'];?>"><br /> <label>Date of birth</label> <input type="text" id="dob" value="<?=$userData['dob'];?>"><br /> <label>Address</label> <input type="text" id="address" value="<?=$userData['address'];?>"> Or pull them using AJAX: $.ajax({ type: "POST", url: config.indexURL + "user", dataType: "json", success: function(data) { $('#username').val(data.username); $('#dateOfBirth').val(data.dob); $('#address').val(data.address); } }); So, which approach is better regarding my application has a complex client-side functionality? In the other hand, PHP-CI has a default mechanism to put the data directly from Controller, so why using AJAX?

• What have you learnt that has a steep learning curve?

  - by Jonathan Khoo

  Recently, I've invested time in learning the intricacies of Git and it has got me thinking about time and learning. (My previous experience with version control systems was only limited use of CVS and SVN.) It took me a whole day's worth of reading to be able to understand the concepts and differences of Git. There are an infinite number of things available for us to learn. Some, more useful than others. I don't know Fortran - I'm relatively young. But looking back at the preceding years of my life, I notice that I'm busier and busier as time goes on. The amount of things I have to get through in a day is increasingly out of my control. It doesn't take a genius to extrapolate that information and realise I'll have even less time in the future - unless I get fired, but I have no strong plans relating to that idea for now. So, given that I have much more time and energy now than I will have in the future: what have you learnt, that has a steep learning curve, that you would possibly recommend to a fellow programmer? Edit: I've stumbled upon the excellent question What programming skills have provided you the best return on investment? and hav realised that my way of approaching how to spend learning time was naive - it doesn't matter if ten useful concepts can be learnt in the time of one if they're worth it.

• Junior software developer - How to understand web applications in depth?

  - by nat_gr

  I am currently a junior developer in web applications and specifically in ASP.NET MVC technology. My problem is that the C# senior developer in the company has no experience with this technology and I try to learn without any guidance. I went through all tutorials (e.g music store), codeplex projects and also read Pro ASP.NET MVC 4. However, most of the examples are about CRUD and e-commerce applications. What I don't understand is how dependency injection fits in web applications (I have realized that is not only used for facilitating unit testing) or when I should use a custom model binder or how to model the business logic when there is already a database schema in place. I read the forum quite often and it would very helpful if some experienced developer could give me an insight about how to proceed. Do I need to read some books to understand the overall idea behind web applications? And what kind of application should I start building myself - I don't think it would be useful to create similar examples with the tutorials.

• Recommended requirements when outsourcing xhtml/css site building?

  - by András Szepesházi

  I'm considering outsourcing a part of our web application development project for freelancers, namely the site building part. What I mean by site building is the process of creating the xhtml/css template files, with dummy content, from a psd file (or any other graphical layout file). The resulting xhtml/css files will be used by our developers as templates for cms based page rendering. The cms in this case is Drupal, but that might not be of much relevance. I'm looking for a good set of requirements, that will result in good quality xhtml/css code, complying with today's standards leaves little to the freelancer developer's imagination in terms of what I need I'm thinking about requirements like: Valid XHTML 1.0 Transitional document type, validated by validator.w3.org Identical rendering in all modern browsers (FF, Chrome, Safari, Opera, IE7-8) and also in IE6 All opening and closing block-level elements should be properly commented, referencing the functional part of the user interface they belong to (menu, toolbar, content, etc) No inline CSS definitions And so on. How would you organize a list like that? What requirements would you add?

• Switching CSS to use asset pipeline in Rails?

  - by John

  I have a lot of legacy CSS files from what was a Rails 2.x app that got upgraded to Rails 3.2.8, and I want to switch over to using the Rails asset pipeline for stylesheets. The issue is, the CSS stuff is messy in terms of huge lines of code, duplicate file names, and unorganized folder structure. After looking through individual pages, and trying to add individual stylesheets and folders into the asset pipeline and spending some cycles debugging, I realized there's probably a better approach. Is there a way to test to make sure the old CSS matches up with the asset pipeline CSS? What are some good tools for testing and debugging CSS?

• Is it a "pattern smell" to put getters like "FullName" or "FormattedPhoneNumber" in your model?

  - by DanM

  I'm working on an ASP.NET MVC app, and I've been getting into the habit of putting what seem like helpful and convenient getters into my model/entity classes. For example: public class Member { public int Id { get; set; } public string FirstName { get; set; } public string LastName { get; set; } public string PhoneNumber { get; set; } public string FullName { get { return FirstName + " " + LastName; } } public string FormattedPhoneNumber { get { return "(" + PhoneNumber.Substring(0, 3) + ") " + PhoneNumber.Substring(3, 3) + "-" + PhoneNumber.Substring(6); } } } I'm wondering people think about the FullName and FormattedPhoneNumber getters. They make it very easy to create standardized data formats throughout the app, and they seem to save a lot of repeated code, but it could definitely be argued that data format is something that should be handled in mapping from model to view-model. In fact, I was originally applying these data formats in my service layer where I do my mapping, but it was becoming a burden to constantly have to write formatters then apply them in many different places. E.g., I use "Full Name" in most views, and having to type something like model.FullName = MappingUtilities.GetFullName(entity.FirstName, entity.LastName); all over the place seemed a lot less elegant than just typing model.FullName = entity.FullName (or, if you use something like AutoMapper, potentially not typing anything at all). So, where do you draw the line when it comes to data formatting. Is it "okay" to do data formatting in your model or is that a "pattern smell"? Note: I definitely do not have any html in my model. I use html helpers for that. I'm strictly talking about formatting or combining data (and especially data that is frequently used).

• force recompilation of war file including its Jar dependencies

  - by Mik378

  I have a project A (a webapp), depending on project B (B.jar) and this one depending on project C (C.jar). I would like to create a maven goal named "Rebuild War", that clean all compiled code for these 3 projects and rebuild the whole in order to obtain a fresh War file. I tried mvn clean package on project A, but I noticed that B and C are not recompiled. Indeed, B.jar and C.jar that are contained in local repository don't have a changing creation date. Is there an adapted maven command for this requirement ?

• Can an issue tracking system be distributed?

  - by Klaim

  I was thinking about issue tracking software like Redmine, Trac or even the one that is in Fossil and something hit me: Is there a reason why Redmine and Trac are not possible to be distributed? Or maybe it's possible and I just don't know how it's possible? If it's not possible, why? By distributed I mean like Facebook or Google or other applications that effectively runs on multiple hardware a the same time but share data.

• Java or Python for internet application?

  - by jpartogi

  In choosing a technology for internet applications where the number of users may scale over time, which one should we consider: Java or Python? What are the considerations in choosing one and not the other? If speed and scalability is our main criteria, which one should we use? We have looked around and it seems that there are more websites that use Python [i.e : Quora, digg, reddit, bitbucket and disqus] than Java. Based on that, can we say that Python is more suitable for internet applications where speed and scalability is the main criteria? However we have browsed around and found some comments saying that Java is actually faster than Python. Thank you for your insights.

• Mobile Apps for Hospitals?

  - by Joey Green

  I currently work for a pretty large hospital and have been dabbling in iPhone development for a couple years. The CEO is wanting to get together a group to see what mobile technology we could create. I was contacted to be the main developer. I wanted to gather some ideas of what kind of mobile apps people have seen deployed in hospitals. Not necessarily medical apps that you can get on the app store, but rather apps built specifically for a hospital. Any ideas? If this is not the appropriate forum for a question like this, can someone point me to a forum where it would be appropriate?

• Tips on googling for sugar

  - by Mikey

  I have a question up on SO I am a little embarassed I can't just google: http://stackoverflow.com/questions/13734664/groovy-variables-in-method-names-with-double-question-marks The problem is google seems to chuck any terms that are just punctuation, so queries like these: .findBy?? .and?? groovy '??' Are coming out the same as these: findBy and groovy I have had this problem before when I didn't know the name of the elvis operator, and countless other times (probably happened first time I saw an infix '%' mod too if I had to guess). Is there a resource for syntax sugar lookups? Some way to force google or a different search engine to not ignore my funky punctuation?

• How can I read data from a generated pointcloud, but from an other perspective of the camera? [migrated]

  - by Vlad Lata

  Basically what I'm trying to do is as follows: I have a software that generates and shows a pointcloud by analyzing Time-of-Flight data (Z-Data). This software has a GUI that delivers this pointcloud on a grid, and you can watch it and adjust the camera to change the perspective, or apply filtering to it and so on. Since the Z-data was recorder through a stereoscopic system, I want to obtain a perspective transformation. My idea was to simply change the position of the camera in the GUI and than add a button that sais (ex. New Perspective) that calls a function that would measure the distances from the existing pointcloud to the camera I'm viewing it from. Of course this would generate some occluded areas, but I want this to happen. And now the main question is: How can I do that? Are there any functions in OpenGL that measure the distance from an object to a camera, or is it even possible to do something like his? Or has someone some other idea? P.S. The software uses the qt sdk and opengl

• Designing javascript chart library

  - by coolscitist

  I started coding a chart library on top of d3js: My chart library. I read Javascript API reusability and Towards reusable charts. However, I am NOT really following the suggestions because I am not really convinced about them. This is how my library can be used to create a bubble chart: var chart = new XYBubbleChart(); chart.data = [{"xValue":200,"yValue":300},{"xValue":400,"yValue":200},{"xValue":100,"yValue":310}]; //set data chart.dataKey.x = "xValue"; chart.dataKey.y = "yValue"; chart.elementId = "#chart"; chart.createChart(); Here are my questions: It does not use chaining. Is it a big issue? Every property and function is exposed publicly. (Example: width, height are exposed in Chart.js). OOP is all about abstraction and hiding, but I don't really see the point right now. I think exposing everything gives flexibility to change property and functionality inside subclasses and objects without writing a lot of code. What could be pitfalls of such exposure? I have implemented functions like: zooming, "showing info boxes when data point is clicked" as "abilities". (example: XYZoomingAbility.js). Basically, such "abilities" accept "chart" object, play around with public variables of "chart" to add functionality. What this allows me to do is to add an ability by writing: activateZoomAbility(chartObject); My goal is to separate "visualization" from "interactivity". I want "interactivity" like: zooming to be plugged into the chart rather than built inside the chart. Like, I don't want my bubble chart to know anything about "zooming". However, I do want zoomable bubble chart. What is the best way to do this? How to test and what to test? I have written mixed tests: jasmine and actual html files so that I can test manually on browser.

• Am I experienced enough to learn and develop immediately using Ruby on Rails?

  - by acheong87

  General Question I understand that discussions revolving around questions of this form run the risk of becoming too specific to help others. So, perhaps a better, general question would be: What kind of experience, if any, translates easily to Ruby on Rails; and if none, then what's the learning curve like, in comparison to other popular languages? Background I have the opportunity to build a website using whatever technologies I wish to use. It's a fairly simple website, for listing products, taking payments, managing customer data, providing a back-end portal for employees to manage data, possibly hooking in flight information (the products are travel related), possibly integrating a blog and all the social-networking goodies. Specific Problem I have to let the client know by tonight whether I'm interested in taking up this project, before he talks to other potential developers, but I'm on the fence. I already work a full-time C++ development job, so the money doesn't do it for me. It's the opportunity to (be paid to) learn some new technologies and to have a real, running product in the end. I've heard and read great things about Ruby, and am really intrigued. I zipped through some introductory Ruby tutorials, no sweat. However I found the Rails tutorials a little overwhelming, especially not being able to try it out anywhere. And researching Rails hosts like Heroku and EngineYard makes me think that maybe I don't know what I'm getting myself into. The ship's leaving port! I wish I had more time to learn, better yet play with the language, but I have to decide soon! Should I venture or pass? Additional Details My experiences are in C/C++/Tcl/Perl/PHP/jQuery, and basic knowledge of Java/C#. I didn't study C.S. formally so I wasn't exposed to design principles, programming paradigms, etc., which is my greatest concern. Will my lack of understanding in this realm make RoR frustrating to learn? Will it be so incompatible with a C++ "way" of thinking that I'll wish I never started? Am I putting my client at risk by attempting this? If it helps, I'm quick to learn new things (self-taught so far) and care a great deal about correctness, using things for their intended purposes, and so on. I've read numerous recommendations of Agile Development with Rails and would love to read it (though perhaps, while developing in parallel, for shortness of time). Worse comes to worst, I'd give up and do the standard LAMP gig, of course, not charging the client for wasted time. But I'm hoping to avoid the project altogether if it's gonna come down to that! Thanks in advance for any tips, insights, votes of confidence, votes of discouragement (for the better), and such.

• High level vs. low level programming. Do I really have to choose?

  - by EpsilonVector

  Every once in a while I'm asked in interviews which I like the best- low level or high level. It seems to me that the implicit message is that they are both a specialty and they want to know which direction I'm heading. The trouble is, I seem to like both. Low level is extremely challenging and often requires a great deal of esoteric knowledge. High level is where all the sexy things happen: applications that people use directly, results that can be easily demonstrated (showed off) in a way that is accessible to everybody, and you get to work with really advanced tools and interact with new technologies. I would really love to do both, even if it means alternating between them (I doubt there are jobs that will let me do both simultaneously), but I'm guessing that the industry rewards specialists more than generalists. Will it really be problematic career wise if I never choose one over the other? Is it practical to alternate between the two in the sense that if I were to leave a job doing one of them, I should experience no "friction" trying to get a job doing the other (assuming I'm reasonably in the loop)? Are there career opportunities where you get to do both? Do I really have to choose one over the other?

• What would you do to improve the working of a small Development team?

  - by Omar Kooheji

  My company is having a reshuffle and I'm applying for my boss' job as he's moved up the ladder. The new role would give me a chance to move our development team into the 21st century and I'd like to make sure that: I can provide sensible suggestions in the interview to get the job so I can fix the team If I get the job I can actually enact some changes to actually improve the lives of the developers and their output. I want to know what I can suggest to improve the way we work, because I think it's a mess but every time I've suggested a change it's been shot down because any time spend implementing the change would be time that isn't spent developing software. Here is the state of play at the moment: My team consists of 3-4 developers (Mainly Java but I do some .Net work) Each member of the team is usually works on 2-3 projects at a time We are each responsible for the entire life cycle of the project from design to testing. Usually only one person works on a project (Although we have the odd project that will have more than one person working on it.) Projects tend to be bespoke to single customer, or are really heavilly reliant on a particular customer environment. We have 2-3 "Products" which we evolve to meet customer requirements. We use SVN for source control We don't do continuous integration (I'd like to start) We use a really basic bug tracker for internal issue tracking (I'd like to move to an issue/task management system) Any changes that bring a sudden dip in revenue generation will probably be rejected, the company isn't structured for development most of the rest of the technical team's jobs can be broken down to install this piece of hardware, configure that piece of hardware and once a job is done it's done and you never have to look at it again. This mentality has crept into development team because it's part of the company culture.

• Why are some seasoned ASP.NET developers defecting to Ruby on Rails?

  - by Tony_Henrich

  Once a while I hear some known ASP.NET developer declaring that they quit developing in .NET and moving to Ruby using Ruby in Rails. The problem is they don't mention exactly the reasons. They use words like RoR is 'easier', 'better' & 'faster'. That really doesn't say much to me. Anyone care to do faithful comparison using code samples, case studies ..etc or from personal experience in using both? Try to convince me to throw away all my years of learning C#, the .NET Framework using a powerful IDE (Visual Studio). Does RoR save you hours a week in development time? What are the major pain points in .NET that compels one to move away from it? This question is NOT about a pure RoR vs ASP.NET (MVC) comparison. It's about the compelling technical reasons (getting bored does not count!) to switch over after using a platform for several years and start with a new language and platform. (prefer this to be a wiki)

• How much detail is in a good UI regression test?

  - by GlenPeterson

  We use a detailed step-by-step user-interface regression test for our commercial web application. It has a "backbone" test for the most used / most important parts of the system, with optional tests for specific areas of functionality. Using this plan has definitely helped us ensure high quality software. But, having very specific tests can be counter-productive. The tester concentrates on following the test and will completely miss usability issues, or not notice fairly obvious problems such as the bottom part of a page that is missing. By contrast, some of the best UI testing happens when building a demo of a new feature. I often do my own best testing by pretending to demonstrate the system to an imaginary prospect. Yet when I tell the testers, "Just demonstrate the system to yourself" they don't cover nearly as much functionality as they do with a detailed point-by-point test. I'm repeatedly asked to provide more and more detail in the test plan so that a new untrained tester can test with it without asking any questions. Yet details seem to be counter-productive. How much detail do you put in a regression test to make it effective? What techniques make the tester to focus more on the system than on checking off items on the test?

• Issuse with multiple student result printing request

  - by dotman14

  I'm not really sure about how to ask this question but i'll try my best to make it clear enough. I have a Student Result Application where by students result are managed, over several academic sessions, all having two semesters each. During each semester students take different courses and have results based on the semester. The application is done now and i'm using a PDF Libaray to crop the final result page to hand over to the students each semester. If a student request a particular semester result it's a straight forward issue and there are no complications when it comes to printing out the result. My issue is this: in a case where a student requests to have a combination of semesters...say 3rd year rain semester , 4th year rain semester and 5th year hamattarn semester. Please how can i handle this issue? Does the user picks these options at the user interface level or there's a special way to handle issues like this? Also, if i'm to display these multiple student result how could this be be done, knowing fully well that i'll have to print the different result seperately. Hopefully i've being able to make my situation clear enough. Thanks for your time and patience. Expecting your comments and answers. Thanks.

• How do I handle 3rd party search result data (via cache)

  - by reikyoushin

  I have a search function on my site and it is taking data from 6 different 3rd party resources. The problem is, it takes too long requesting the data over and over again on the results page. I've read for questions like this on SO about session not being a good choice but for me 'memcache' is not an option, because the server doesn't have memcached installed and I have no way to install it now. Is there any other approach to do this? Storing in the database seem inappropriate because the data depends on the search terms requested. What I've been thinking is writing a file on the server that would act as a cache for this file but I don't know how I would know when to delete it after.

• Good approach for hundreds of comsumers and big files

  - by ????? ???????

  I have several files (nearly 1GB each) with data. Data is a string line. I need to process each of these files with several hundreds of consumers. Each of these consumers does some processing that differs from others. Consumers do not write anywhere concurrently. They only need input string. After processing they update their local buffers. Consumers can easily be executed in parallel. Important: With one specific file each consumer has to process all lines (without skipping) in correct order (as they appear in file). The order of processing different files doesn't matter. Processing of a single line by one consumer is comparably fast. I expect less than 50 microseconds on Corei5. So now I'm looking for the good approach to this problem. This is going to be be a part of a .NET project, so please let's stick with .NET only (C# is preferable). I know about TPL and DataFlow. I guess that the most relevant would be BroadcastBlock. But i think that the problem here is that with each line I'll have to wait for all consumers to finish in order to post the new one. I guess that it would be not very efficient. I think that ideally situation would be something like this: One thread reads from file and writes to the buffer. Each consumer, when it is ready, reads the line from the buffer concurrently and processes it. The entry from the buffer shouldn't be deleted as one consumer reads it. It can be deleted only when all consumers have processed it. TPL schedules consumer threads itself. If one consumer outperforms the others, it shouldn't wait and can read more recent entries from the buffer. Am i right with this kind of approach? Whether yes or not, how can i implement the good solution? A bit was already discussed on StackOverflow: link
