  • Why write clean, refactored code?

    - by Shamal Karunarathne
    Hi programming lovers, This is a question I've been asking myself for a long time. Thought of throwing out it to you. From my experience of working on several Java based projects, I've seen tons of codes which we call 'dirty'. The unconventional class/method/field naming, wrong way of handling of exceptions, unnecessarily heavy loops and recursion etc. But the code gives the intended results. Though I hate to see dirty code, it's time taking to clean them up and eventually comes the question of "is it worth? it's giving the desired results so what's the point of cleaning?" In team projects, should there be someone specifically to refactor and check for clean code? Or are there situations where the 'dirty' codes fail to give intended results or make the customers unhappy? Do feel free to comment and reply. And tell me if I'm missing something here. Thanks.

  • How do I get the source code from a Google Code game project?

    - by BluFire
    I'm trying to get the Hedgewars source code. When I went to the downloads tab, it doesn't specify which is the actual game. I tried downloading it using the SVN Checkout on Tortoise, but it seems like it doesn't work on the browse section of Source. (Hgproject_filesAndroid_buildSDL-android-project) I then proceeded to the wiki but I got stuck at step two because I don't know anything about Mercurial. Some other things I don't know from the wiki is "FreePascal" "Android NDK" and "Tar" files. They are new to me so I am really confused. So my question is, how can I download the source code from Hedge Wars for Android without having to browse the source code inside the source tab?

  • EF4 CTP5 Code First approach ignores Table attributes

    - by Justin
    I'm using EF4 CTP5 code first approach but am having trouble getting it to work. I have a class called "Company" and a database table called "CompanyTable". I want to map the Company class to the CompanyTable table, so have code like this: [Table(Name = "CompanyTable")] public class Company { [Key] [Column(Name = "CompanyIdNumber", DbType = "int")] public int CompanyNumber { get; set; } [Column(Name = "CompanyName", DbType = "varchar")] public string CompanyName { get; set; } } I then call it like so: var db = new Users(); var companies = (from c in db.Companies select c).ToList(); However it errors out: Invalid object name 'dbo.Companies'. It's obviously not respecting the Table attribute on the class, even though it says here that Table attribute is supported. Also it's pluralizing the name it's searching for (Companies instead of Company.) How do I map the class to the table name?

  • How can I quantify the amount of technical debt that exists in a project?

    - by Erik Dietrich
    Does anyone know if there is some kind of tool to put a number on technical debt of a code base, as a kind of code metric? If not, is anyone aware of an algorithm or set of heuristics for it? If neither of those things exists so far, I'd be interested in ideas for how to get started with such a thing. That is, how can I quantify the technical debt incurred by a method, a class, a namespace, an assembly, etc. I'm most interested in analyzing and assessing a C# code base, but please feel free to chime in for other languages as well, particularly if the concepts are language transcendent.

  • Code review versus pair programming

    - by mericano1
    I was wondering what is the general idea about code review and pair programming. I do have my own opinion but I'd like to hear from somebody else as well. Here are a few questions, please give me your opinion even on some of the point First of all are you aware of way to measure the effectiveness of this practices? Do you think that if you pair program, code reviews are not necessary or it's still good to have them both? Do you think anybody can do code review or maybe is better done by seniors only? In terms of productivity do you think it suffers from pairing all the times or you will eventually get in back in the long run?

  • Is committing/checking code everyday a good practice?

    - by ArtB
    I've been reading Martin Fowler's note on Continuous Integration and he lists as a must "Everyone Commits To the Mainline Every Day". I do not like to commit code unless the section I'm working on is complete and that in practice I commit my code every three days: one day to investigate/reproduce the task and make some preliminary changes, a second day to complete the changes, and a third day to write the tests and clean it up^ for submission. I would not feel comfortable submitting the code sooner. Now, I pull changes from the repository and integrate them locally usually twice a day, but I do not commit that often unless I can carve out a smaller piece of work. Question: is committing everyday such a good practice that I should change my workflow to accomodate it, or it is not that advisable? ^ The order is more arbitrary and depends on the task, my point was to illustrate the time span and activities, not the exact sequence.

  • Simplicity-efficiency tradeoff

    - by sarepta
    The CTO called to inform me of a new project and in the process told me that my code is weird. He explained that my colleagues find it difficult to understand due to the overly complex, often new concepts and technologies used, which they are not familiar with. He asked me to maintain a simple code base and to think of the others that will inherit my changes. I've put considerable time into mastering LINQ and thread-safe coding. However, others don't seem to care nor are impressed by anything other than their paycheck. Do I have to keep it simple (stupid), just because others are not familiar with best practices and efficient coding? Or should I continue to do what I find best and write code my way?

  • Building a code search engine for java code in git repositories

    - by zero1
    I'm trying to build a Java code search engine. Apart from just searching for keywords, I would also like cross-referencing between classes to work. It should work the way eclipse's referencing works - click on anything to open the definition. Bonus would be if something like search-all-usages-of-foo works. I'm thinking of using Apache Solr to index the files and build the basic search. But I'm not sure how I'd do the crossreferencing part since Solr doesn't understand Java code. Any suggestions on what I could use here? EDIT: I mainly want to index a lot of java git repositories.

  • Code Trivia: optimize the code for multiple nested loops

    - by CodeToGlory
    I came across this code today and wondering what are some of the ways we can optimize it. Obviously the model is hard to change as it is legacy, but interested in getting opinions. Changed some names around and blurred out some core logic to protect. private static Payment FindPayment(Order order, Customer customer, int paymentId) { Payment payment = Order.Payments.FindById(paymentId); if (payment != null) { if (payment.RefundPayment == null) { return payment; } if (String.Compare(payment.RefundPayment, "refund", true) != 0 ) { return payment; } } Payment finalPayment = null; foreach (Payment testpayment in Order.payments) { if (testPayment.Customer.Name != customer.Name){continue;} if (testPayment.Cancelled) { continue; } if (testPayment.RefundPayment != null) { if (String.Compare(testPayment.RefundPayment, "refund", true) == 0 ) { continue; } } if (finalPayment == null) { finalPayment = testPayment; } else { if (testPayment.Value > finalPayment.Value) { finalPayment = testPayment; } } } if (finalPayment == null) { return payment; } return finalPayment; } Making this a wiki so code enthusiasts can answer without worrying about points.

  • Code Camp 2011 – Summary

    - by hajan
    Waiting whole twelve months to come this year’s Code Camp 2011 event was something which all Microsoft technologies (and even non-Microsoft techs.) developers were doing in the past year. Last year’s success was enough big to be heard and to influence everything around our developer community and beyond. Code Camp 2011 was nothing else but a invincible success which will remain in our memory for a long time from now. Darko Milevski (president of MKDOT.NET UG and SharePoint MVP) said something interesting at the event keynote that up to now we were looking at the past by saying what we did… now we will focus on the future and how to develop our community more and more in the future days, weeks, months and I hope so for many years… Even though it was held only two days ago (26th of November 2011), I already feel the nostalgia for everything that happened there and for the excellent time we have spent all together. ORGANIZED BY ENTHUSIASTS AND EXPERTS Code Camp 2011 was organized by number of community enthusiasts and experts who have unselfishly contributed with all their free time to make the best of this event. The event was organized by a known community group called MKDOT.NET User Group, name of a user group which is known not only in Macedonia, but also in many countries abroad. Organization mainly consists of software developers, technical leaders, team leaders in several known companies in Macedonia, as well as Microsoft MVPs. SPEAKERS There were 24 speakers at five parallel tracks. At Code Camp 2011 we had two groups of speakers: Professional Experts in various technologies and Student Speakers. The new interesting thing here is the Student Speakers, which draw attention a lot, especially to other students who were interested to see what their colleagues are going to speak about and how do they use Microsoft technologies in different coding scenarios and practices, in different topics. From the rest of the professional speakers, there were 7 Microsoft MVPs: Two ASP.NET/IIS MVPs, Two C# MVPs, and One MVP in SharePoint, SQL Server and Exchange Server. I must say that besides the MVP Speakers, who definitely did a great job as always… there were other excellent speakers as well, which were speaking on various technologies, such as: Web Development, Windows Phone Development, XNA, Windows 8, Games Development, Entity Framework, Event-driven programming, SOLID, SQLCLR, T-SQL, e.t.c. SESSIONS There were 25 sessions mainly all related to Microsoft technologies, but ranging from Windows 8, WP7, ASP.NET till Games Development, XNA and Event-driven programming. Sessions were going in five parallel tracks named as Red, Yellow, Green, Blue and Student track. Five presentations in each track, each with level 300 or 400. More info MY SESSION (ASP.NET MVC Best Practices) I must say that from the big number of speaking engagements I have had, this was one of my best performances and definitely I have set new records of attendees at my sessions and probably overall. I spoke on topic ASP.NET MVC Best Practices, where I have shown tips, tricks, guidelines and best practices on what to use and what to avoid by developing with one of the best web development frameworks nowadays, ASP.NET MVC. I had approximately 350+ attendees, the hall was full so that there was no room for staying at feet. Besides .NET developers, there were a lot of other technology oriented developers, who has also received the presentation very well and I really hope I gave them reason to think about ASP.NET as one of the best options for web development nowadays (if you ask me, it’s the best one ;-)). I have included 10 tips in using ASP.NET MVC each of them followed by a demo. Besides these 10 tips, I have briefly introduced the concept of ASP.NET MVC for those that haven’t been working with the framework and at the end some bonus tips. I must say there was lot of laugh for some funny sentences I have stated, like “If you code ASP.NET MVC, girls will love you more” – same goes for girls, only replace girls with boys :). [LINK TO SESSION WILL GO HERE, ONCE SESSIONS ARE AVAILABLE ON MK CODECAMP WEBSITE] VOLUNTEERS Without strong organization, such events wouldn’t be able to gather hundreds of attendees at one place and still stay perfectly organized to the smallest details, without dedicated organization and volunteers. I would like to dedicate this space in my blog to them and to say one big THANK YOU for supporting us before the event and during the whole day in the event. With such young and dedicated volunteers, we couldn’t achieve anything but great results. THANK YOU EVERYONE FOR YOUR CONTRIBUTION! NETWORKING One of the main reasons why we do such events is to gather all professionals in one place. Networking is what everyone wants because through this way of networking, we can meet incredible people in one place. It is amazing feeling to share your knowledge with others and exchange thoughts on various topics. Meet and talk to interesting people. I have had very special moments with many attendees especially after my presentation. Special Thank You to all of them who come to meet me in person, whether to ask a question, say congrats for my session or simply meet me and just smile :)… everything counts! Thank You! TWITTER During the event, twitter was one of the most useful event-wide communication tool where everyone could tweet with hash tag #mkcodecamp or #mkdotnet and say what he/she wants to say about the current state and happenings at that moment… In my next blog post I will list the top craziest tweets that were posted at this event… FUTURE OF MKDOT.NET Having such strong community around MKDOT.NET, the future seems very bright. The initial plans are to have sub-groups in several technologies, however all these sub-groups will belong to the MKDOT.NET UG which will be, somehow, the HEAD of these sub-groups. We are doing this to provide better divisions by technologies and organize ourselves better since our community is very big, around 500 members in MKDOT.NET.We will have five sub-groups:- Web User Group (Lead:Hajan Selmani - me)- Mobile User Group (Lead: Filip Kerazovski)- Visual C# User Group (Lead: Vekoslav Stefanovski)- SharePoint User Group (Lead: Darko Milevski)- Dynamics User Group (Lead: Vladimir Senih) SUMMARY Online registered attendees: ~1.200 Event attendees: ~800 Number of members in organization: 40+ Organized by: MKDOT.NET User Group Number of tracks: 5 Number of speakers: 24 Number of sessions: 25 Event official website: http://codecamp.mkdot.net Total number of sponsors: 20 Platinum Sponsors: Microsoft, INETA, Telerik Place held: FON University City and Country: Skopje, Macedonia THANK YOU FOR BEING PART OF THE BEST EVENT IN MACEDONIA, CODE CAMP 2011. Regards, Hajan

  • Working with Legacy code #4 : Remove the hard dependencies

    - by andrewstopford
    During your refactoring cycle you should be seeking out the hard dependencies that the code may have, examples of these can include. File System Database Network (HTTP) Application Server (Crystal) Classes that service these kind (or code that can be abstracted to a class) of these kind of dependencies should be wrapped in an interface for easier mocking. If you team starts refering to the interface version of these classes the hard dependency will over time work it's self free.

  • Unit testing code paths

    - by Michael
    When unit testing using expectations, you define a set of method calls and corresponding results for those calls. These define the path through the method that you want to test. I have read that unit tests should not duplicate the code. But when you define these expectations, isn't that duplicating the code, or at least the process? How do you know when you're duplicating functionality under test?

  • Emphasize Some Comments - but not Dirty the Code

    - by Jon Sandness
    I'm having trouble structuring my comments at the moment. I have major sections of the code that, when scrolling through the document, I want to be able to see those stand out. Examples: This is a normal comment: int money = 100; //start out with 100 money - This is a comment to emphasize a certain part of the code: /****** Set up all the money ******/ But I don't like that this isn't very clean. Is there a standard way of setting up this type of a comment?

  • What's the best language combo for code generation?

    - by Peter Turner
    I read through Code Generation in Action but never bothered to make anything of it because Ruby just doesn't fit with my lifestyle at this juncture. The book came out more on the cusp of the C# revolution, and it said that C# "was a language designed to be generated", apparently using Ruby as the generator language. In your experience, what is the ideal combination of languages to generate the most useful code?

  • Quality of Code in unit tests?

    - by m3th0dman
    Is it worth to spend time when writing unit tests in order that the code written there has good quality and is very easy to read? When writing this kinds of tests I break very often the Law of Demeter, for faster writing and not using so many variables. Technically, unit tests are not reused directly - are strictly bound to the code so I do not see any reason for spending much time on them; they only need to be functionaly.

  • What should come first: testing or code review?

    - by Silver Light
    Hello! I'm quite new to programming design patterns and life cycles and I was wondering, what should come first, code review or testing, regarding that those are done by separate people? From the one side, why bother reviewing code if nobody checked if it even works? From the other, some errors can be found early, if you do the review before testing. Which approach is recommended and why? Thank you!
