  • Call C methods from C++/Java/C# code?

    - by Mohit Deshpande
    Many of today's programming languages are based on C; like C++, C#, Java, Objective-C. So could I call a C method from C++ code? Or call C from Java or C#? Or is this goal out of reach and unreasonable? Please include a quick code sample for my and everyone else's understanding.

  • lambda vs. operator.attrgetter('xxx') as sort key function in Python

    - by Paul McGuire
    I am looking at some code that has a lot of sort calls using comparison functions, and it seems like it should be using key functions. If you were to change seq.sort(lambda x,y: cmp(x.xxx, y.xxx)), which is preferable: seq.sort(key=operator.attrgetter('xxx')) or: seq.sort(key=lambda a:a.xxx) I would also be interested in comments on the merits of making changes to existing code that works.

  • C#: Specify that a function arg must inhert from one class, and implement an interface?

    - by Rosarch
    I'm making a game where each Actor is represented by a GameObjectController. Game Objects that can partake in combat implement ICombatant. How can I specify that arguments to a combat function must inherit from GameObjectController and implement ICombatant? Or does this indicate that my code is structured poorly? public void ComputeAttackUpdate(ICombatant attacker, AttackType attackType, ICombatant victim) In the above code, I want attacker and victim to inherit from GameObjectController and implement ICombatant. Is this syntactically possible?

  • How to minimize code area in Eclipse?

    - by Stella
    There is a nice feature in Visual Studio: you can create special code areas which can be minimized just as class methods in Eclipse are minimized. Like: #region //some code #endregion Is there a way do make such pleasant feature in Eclipse?

  • Expanding collapsed code in Eclipse IDE

    - by rabin
    Instead of going through each (+) sign at the left and clicking them to expand the collapsed code snippets, is there a shortcut or menu item (I couldn't find it, VS has that) to expand all the collapsed code/comments at once? Thanks.

  • How do you safely work around broken code? [closed]

    - by burnt1ce
    Once in a while, a co-worker will check-in bad code which blocks my application from initializing properly. To get around this problem quickly, I comment out the offending code. I then forget to uncomment the offending code at the time of my check-in, so I want to prevent this from happening again. Do you have any suggestions on how to: Disable bad code that stop you from working Prevent yourself from checking in unwanted changes? I'm currently using Visual Studio as my IDE and TFS as my source code repo.

  • How do you safely comment out code in Visual Studio and TFS?

    - by burnt1ce
    Once in a while, a co-worker check-ins bad code and this blocks you from your application from initializing properly so you can continue doing your work. To get around this problem quickly, I've commented out the offending code. I accidentally to uncomment out the offending code at the time of check-in and I want to prevent this from happening again. Do you have a trick to 1) disable bad code that stop you from working 2) prevent yourself from checking in unwanted changes?

  • Should my colleagues review each others code from source control system?

    - by Daniel Excinsky
    Hi everybody. So that's my story: one of my colleagues uses to review all the code, hosted to revision system. I'm not speaking about adequate review of changes in parts that he belongs to. He watches the code file to file, line to line. Every new file and every modified. I feel just like being spied on! My guess is that if code was already hosted to control system, you should trust it as workable at least. My question is, maybe I'm just too paranoiac and practice of reviewing each others code is good? P.S: We're team of only three developers, and I fear that if there will be more of us, colleague just won't have time to review all the the code we'll write.

  • Have you downloaded the All-In-One Code Framework?

    - by Eric Nelson
    The Microsoft All-In-One Code Framework is a free, centralized code sample library provided by the Microsoft Community team. It aims to provide typical code samples for all Microsoft development technologies. The team listens to developers’ pains in MSDN forums, social media and various developer communities and write code samples based on developers’ frequently asked programming tasks. Additionally, our team offers a free code sample request service. Awesome?! I think so. Have also just added it to 99 technical resources for developers and architects inside ISVs – also worth checking out. Check it out on codeplex

  • How to document and teach others "optimized beyond recognition" computationally intensive code?

    - by rwong
    Occasionally there is the 1% of code that is computationally intensive enough that needs the heaviest kind of low-level optimization. Examples are video processing, image processing, and all kinds of signal processing, in general. The goals are to document, and to teach the optimization techniques, so that the code does not become unmaintainable and prone to removal by newer developers. (*) (*) Notwithstanding the possibility that the particular optimization is completely useless in some unforeseeable future CPUs, such that the code will be deleted anyway. Considering that software offerings (commercial or open-source) retain their competitive advantage by having the fastest code and making use of the newest CPU architecture, software writers often need to tweak their code to make it run faster while getting the same output for a certain task, whlist tolerating a small amount of rounding errors. Typically, a software writer can keep many versions of a function as a documentation of each optimization / algorithm rewrite that takes place. How does one make these versions available for others to study their optimization techniques?

  • Making it myself vs. modifying someone else's code as a beginner

    - by JamesGold
    I just started getting into open source projects mainly for the learning experience. I've made a few tiny contributions to some small projects. Most of my time has been spent just reading over other people's code and trying to understand how it works. Often times I find myself frustrated by a lack of documentation and unit tests. There are also times where I think I can see a more intuitive solution to a problem, but implementing it would require large restructuring of code. I see all this and wonder to myself why I don't just start clean on the whole thing by myself and do things "the right way"? I'd also enjoy the experience of building it from scratch, as it would force me to learn skills that I might not learn by working on other people's code. On the other hand, working on other people's code is also a great experience because it requires me to understand and work with other people's code and collaborate with them. It's just harder, IMO. Thoughts?

  • How do you explain commented-out code to a non-programmer? [closed]

    - by whirlwin
    What is the quickest and most comprehensible way to explain to a non-programmer what commented-out code is? When I mentioned it in a conversation to non-programmers, they seemed lost. Such people could for instance be graphical designers, when working on the same team to make an application. Typically I would need to mention what I will be/currently am working with during an update meeting. At first I thought about substituting commented-out with unused code. While it is true to some degree, it is also very ambiguous. If you are wondering, I am working with legacy code with commented-out code. This leads to my question: "how do you explain commented-out code to a non-programmer?"

  • Is it OK to push my code to GitHub while it is still in early development?

    - by marco-fiset
    I have some projects that are in a very early development state. They are nowhere nearing completion but I do host them (as public repos) on GitHub because: I have multiple computers and I want access to my code everywhere I want a backup for my code I want it to be easy if someone wants to collaborate in some way I use GitHub Issues as a poor man's project management software Is it OK to publish a project on GitHub even when it is very early in the development? I am a bit concerned about someone to come by and say OMG this is total BS, this code is so bad! while looking at unpolished/still in development/not tested code. What are your practices when you start new public projects? Do you wait until you have something substantial to show or you create a bare repo directly on GitHub and start from there? I used GitHub throughout this post but this applies to every code hosting service out there.
