  • Brief material on C++ object-lifetime management and on passing and returning values/references

    - by dsign
    I was wondering if anybody can point to a post, pdf, or excerpt of a book containing the rules for C++ variable life-times and best practices for passing and returning function parameters. Things like when to pass by value and by reference, how to share ownership, avoid unnecessary copies, etc. This is not for a particular problem of mine, I've been programming in C++ for long enough to know the rules by instinct, but it is something that a lot of newcomers to the language stumble with, and I would be glad to point them to such a thing.

  • Do not expose enum in WCF response

    - by Michael Freidgeim
    We had a backward compatibility problem in WCF client, when in Service application a new value was added to one of enums. We discussed different ways to avoid this backward compatibility issues, and I found recommendation do not expose enum in wcf response in http://stackoverflow.com/a/788281/52277.It is still required to create new versions of our service interfaces to replace each enum fields with string field, that expects only documented values, and describe, what should be default behavior, if field has an unexpected value.

  • Should the test and the fix be written by different people?

    - by Nutel
    There is a common practice in TDD to write a test before fix to avoid regression and simplify fixing. I just wonder what if the test and fix will be written by different people, total spent time will be almost the same but as now three people will think about possible failures (+tester) we increase probability that fix will cover all possible failure scenarios. Does this practice make sense or it will just waste additional time needed for one more person to familiarize with bug?

  • ToolTip flicker in Java if outside JFrame? [closed]

    - by Skarion
    Hi! I am implementing ToolTip in Java as to make users having an easier time to use the product. Though tooltip that are at the borders of the JFrame and ends up outside the JFrame starts to "flicker".

Anyone got any expertise within the field that know how to avoid this problem? Cheers, Skarion

  • Should I use multiple column primary keys or add a new column?

    - by Covar
    My current database design makes use of a multiple column primary key to use existing data (that would be unique anyway) instead of creating an additional column assigning each entry an arbitrary key. I know that this is allowed, but was wondering if this is a practice that I might want to use cautiously and possibly avoid (much like goto in C). So what are some of the disadvantages I might see in this approach or reasons I might want a single column key?

  • Reliable Storage Systems for SQL Server

    By validating the IO path before commissioning the production database system, and performing ongoing validation through page checksums and DBCC checks, you can hopefully avoid data corruption altogether, or at least nip it in the bud. If corruption occurs, then you have to take the right decisions fast to deal with it. Rod Colledge explains how a pessimistic mindset can be an advantage

  • What should a Python developer know while learning Ruby?

    - by C J
    I have been a Python programmer for about 18 months, consisting of one internship and a few side projects, and I consider myself pretty comfortable in the language. However, there seems to be a lot of attention on Ruby in the programming field, but not a lot on Python anymore. So in learning Ruby, are there going to be Pythonic things that are just bad practices in Ruby? What should I watch out for, and what should I avoid?

  • MMO Web game mouse vs wasd

    - by LazyProgrammer
    If considering to develop a web browser based game with multiple people and it's an RPG, click to move would probably be the only choice in movement right? Because if you were to use WASD and then ajax to the server every second that a player held on to the WASD key, that'd be pretty resource intensive if the server had to calculate the position and return the map image, assuming the next few screens are already buffered right? or is there a way to implement a WASD style and still have server side do all the calculations. (server side calculations to avoid cheating)

  • Recommended readings for a sofware construction mini-course [on hold]

    - by Aivar
    I'm going to organize a mini-course for CS students who have completed CS1 (Python) and CS2 (Java). I'd like to show them more principled approach to programming practice and design, something along the lines of McConnel's Code Complete. If I had enough copies of Code Complete, I would assign some readings from that book. Can you recommend some freely available material (books, blog posts, articles, essays) for such a course? (I'd prefer to avoid topics specific to OOP and focus on more universal principles.)

  • Implenting ActiveRecord with inheritance?

    - by King
    I recently converted an old application that was using XML files as the data store to use SQL instead. To avoid a lot of changes I basically created ActiveRecord style classes that inherited from the original business objects. For example SomeClassRecord :SomeClass //ID Property //Save method I then used this new class in place of the other one, because of polymorphism I didn't need to change any methods that took SomeClass as a parameter. Would this be considered 'Bad'? What would be a better alternative?
