  • Is avoiding the private access specifier in PHP justified?

    - by Tifa
    I come from a Java background and I have been working with PHP for almost a year now. I have worked with WordPress, Zend and currently I'm using CakePHP. I was going through Cake's lib and I couldn't help notice that Cake goes a long way avoiding the "private" access specifier. Cake says Try to avoid private methods or variables, though, in favor of protected ones. The latter can be accessed or modified by subclasses, whereas private ones prevent extension or re-use. in this tutorial. Why does Cake overly shun the "private" access specifier while good OO design encourages its use i.e to apply the most restrictive visibility for a class member that is not intended to be part of its exported API? I'm willing to believe that "private" functions are difficult test, but is rest of the convention justified outside Cake? or perhaps it's just a Cake convention of OO design geared towards extensibility at the expense of being a stickler for stringent (or traditional?) OO design?

  • How are Programming Languages Designed?

    - by RectangleTangle
    After doing a bit of programming, I've become quite curious on language design itself. I'm still a novice (I've been doing it for about a year), so the majority of my code pertains to only two fields (GUI design in Python and basic algorithms in C/C++). I have become intrigued with how the actual languages themselves are written. I mean this in both senses. Such as how it was literally written (ie, what language the language was written in). As well as various features like white spacing (Python) or object orientation (C++ and Python). Where would one start learning how to write a language? What are some of the fundamentals of language design, things that would make it a "complete" language?

  • 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

  • Multitasking or Tombstoning and Isolated Storage in Windows Phone 7

    Windows Phone 7 manages multiple active applications by implementing a stack. In a sense, this application stack extends the page stack within a single Silverlight program. You can think of the phone as an old-fashioned web browser with no tab feature and no Forward button. But it does have a Back button and it also has a Start button, which brings you to the Start screen and allows you to launch a new program.

  • Question about design

    - by lukeluke
    Two fast questions about two design decisions: Suppose that you are checking collisions between game elements. When you find a collision between object 1 and object 2, do you play immediately a sound effect or do you insert it in a list and, in a later a stage, do you process all sound effects? Same question as above for user input. When the user presses key 'keypad left' do you insert the event in a queue and process it later or do you update character position immediately? Thx

  • Languages and tools that are "portable" (work well from a USB storage drive) [closed]

    - by CodexArcanum
    I'm a huge fan of running programs from my portable hard drive: it means I always have my favorite tools no matter what computer I'm on. Sadly, development tools seem to be hard to get portable at times. I recently realized that the "portable" version of MinGW I was using off my USB drive was actually interfering with a locally installed version of MinGW, so sometimes even the tools you think are portable, aren't. So what are the best portable development tools that you've used? What runs well on a portable media, leaves the host machine clean, and generally makes moving around easier for you?

  • Estimates, constraint and design [closed]

    - by user65964
    For your next two software projects (assuming that you're getting programming assignments, otherwise consider the program to find the min and max of a set of rational numbers) estimate how much effort they would take before doing them, then keep track of the actual time spent. How accurate were your estimates? State the requirements, constraint, design, estimate (your original estimate and the actual time it took), implementation (conventions used, implement/test path followed.

  • Use Thread-local Storage to Reduce Synchronization

    Synchronization is often an expensive operation that can limit the performance of a multithreaded program. Using thread-local data structures instead of data structures shared by the threads can reduce synchronization in certain cases, allowing a program to run faster.
