  • Imperative vs. component based programming [closed]

    - by AlexW
    I've been thinking about how programming and more specifically the teaching of programming is advocated amongst the community (online). Often I've heard that Ruby and RoR is an ideal platform for learning to program. I completely disagree... RoR and Ruby are based on the application of the component based paradigm, which means they are ideal for rapid application development. This is much like the MVC model in PHP and ASP.NET But, learning a proper imperative language like Java or C/C++ (or even Perl and PHP) is the only way for a new programmer to explore logic itself, and not get too bogged down in architectural concerns like the need for separation of concerns, and the preference for components. Maybe it's a personal preference thing. I rather think that the most interesting aspects to programming are the procedural bits of code I write that actually do stuff rather than the project planning, and modelling that comes about from fully object oriented engineering or simply using the MVC model. I know this may sound confused to some of you. I feel strongly though that the best way for programming to be taught is through imperative and procedural methods. Architectural (component) methods come later, if at all. After all, none of the amazing algorithms that exist were based on OOP practice! It's all procedural code when it comes to the 'magic'. OOP is useful in creating products and utilities. Algorithms are what makes things happen, and move data around, and so imperative (and/or procedural) code are what matters most. When I see programmers recommending Ruby on Rails to newbie developers, I think it's just so wrong. Just because you write less code with Ruby does not make it easier to do! It's the opposite... you have to know loads more to appreciate its succinct nature. New coders who really want to understand the nuts and bolts of coding need to go away and figure out writing methods/functions (i.e. imperative programming) and working in procedural style, in order to grasp the fundamentals, first, before looking into architectural ways of working. So, my question is: should Ruby ever be recommended as a first language? I think no (obviously)... what arguments are there for it?

  • What's the point of initializing a variable with the same value twice?

    - by JoeM05
    I was reading Ben Cherry's "JavaScript Module Pattern: In-Depth", and he had some example code that I didn't quite understand. Under the Cross-File Private State heading, there is some example code that has the following: var _private = my._private = my._private || {} This doesn't seem to be different from writing something like this: var _private = my._private || {} What's happening here and how are these two declarations different?

  • Kernel Panic while Installing Ubuntu 12.10 from USB Drive

    - by user100889
    Good evening, I recently looked into installing Ubuntu alongside my Windows. I was able to mount the iso on a USB drive using Universal USB Installer. I verified it with the MD5sum utility and the hash is correct. When installing, I can get to the screen where I choose the boot order, select the USB drive, and then I get to a screen where Ubuntu seems to be 'loading' (purple background with Ubuntu logo and name in the middle). Then, all of a sudden, I get a "Kernel Panic - Not syncing: fatal exception in interrupt" error message. My specs : Intel Core 2 Duo CPU T5850 @ 2.16 GHz / 4 GB of ram / Packard Bell computer from 2007. / Windows 7 Ultimate x64 installed. What should I do now ? Thanks for your help.

  • Chrome Mobile: The Mobile Web Developers Toolkit (Part 1)

    Chrome Mobile: The Mobile Web Developers Toolkit (Part 1) Building for mobile web requires a different mindset than desktop web development, and a different set of tools. The tools we're used to using often aren't available or would take up too much screen real estate. And going back to the dark ages of tweak/save/deploy/test/repeat isn't exactly optimal, so what can we do? Thankfully there are a number of great options - from remote debugging to emulation, mobile browsers are offering more and more tools to make our lives easier. We'll take a look at a couple of tools that you can use today to make cross platform mobile web development easier and then peer into the crystal ball to see what tools may bring in the future. Join us for Part 1 - as we take a look at a few boiler plates, frameworks and helpful libraries for building the mobile web.
