  • What's the DCPU-16 thing all about?

    - by ChrisRamakers
    Ever since Notch (of Minecraft fame) announced his next project will include programmable 16bit cpu's ingame everybody seems to want to write VM's for the spec notch has written up. I've seen em written in C, C++, go, javascript, coffeescript, ... Can anyone enlighten me what's so special about the spec notch wrote up or is it just that it's the first game that actually contains a CPU ingame that you can do whatever you want with? It sparked my curiosity but I fail to grasp the thing that makes it so special suddenly everybody needs to write up code for it?

  • Best Resources for learning SQL? [closed]

    - by Simon
    Possible Duplicate: Good Books and videos for absolute beginner to SQL I have landed a role as a product engineer for a web based product. A big part of the product is allowing its users the ability to create queries with SQL to pull in business information from their back end databases. I know the very basics of SQL and need to spend some time getting a better grasp on SQL. I have the tutorial from w3schools on my ToDo list, but was hoping to get some answers that point me to good resources for learning SQL. I have no preference - I can buy a book (SQL For Dummies?), or online resources, online videos, audio, etc.

  • Web Development Internship Interview Help

    - by Todd
    Tomorrow morning I'm interviewing for a web development internship position and I'm seeking general advice pertaining to the questions that interviewers might ask, some questions I should ask them during the interview, and any general tips/suggestions that might help. They're looking for someone with knowledge mainly in HTML/CSS, Joomla, MySQL and PHP, all of which I have excluding Joomla (which I'm installing/doing as much research on as possible at the moment) and I was able to provide them a link to a site I'd been paid to build for a small business which they mentioned they were impressed with. I'd like to prepare myself for the interview as much as I possibly can but I'm wondering how much time I should spend rehashing elements of the languages they're looking for, or if it'd be a better use of my time to research their company and figure out how I'd respond to general questions. I feel that perhaps because I showed them a project I've completed that they'll know that I can grasp the technical side of what they're going for... but this is my first internship interview in this field so I'm not exactly sure what to expect. Thanks

  • Published Windows Phone 7 apps: good for the Resume/CV?

    - by pearcewg
    I'm a long time Microsoft developer who has recently started publishing Windows Phone 7 apps to beef up my current C#/.NET skills, and get more direct exposure to WPF/Silverlight, and of course because it is new and cool. So far I've published over 10 apps successfully. Is this a good thing to put on my resume? Does it appear to show a grasp of the latest Microsoft technologies? Any downside seen by potential employers? Would you put this on your resume, if looking for a full time professional Software Engineering position?

  • Search engine friendly, SEO blog software

    - by Steve
    Is there a comparison of the SEO capabilities of different blogging software/blogging plugins? I'd like things to be as optimised as possible. I have a basic grasp of SEO principles, probably 12-24 months old. I'm about to start a blog, after having a few previously. Also, I'm not up to speed on what pings are in the blogging world. What are they, and how do they work? I assume it is best to have blogging software that automatically pings.

  • Which programming language to go for in order to learn Object Oriented Programming? [closed]

    - by Maxood
    If someone has a good grasp in logic and procedural programming then which language to start with for learning OOP. Also why C++ is mostly taught at schools whereas Java is a pure Object Oriented language(also language for making android apps)? Why not Objective C is being taught for making apps on the iPhone? I am seeking for the right answer keeping in view of these 2 factors: Background of the learner in procedural programming Economic or job market market demand of programming languages Here is a list of 10 programming languages, i would like to seek justifications for: Java C++ Objective C Scala C# PHP Python Java Javascript (not sure if it is a fully featured OOP language) 10.Ruby (not sure if it is a fully featured OOP language)

  • How do you deal with the details when reading code?

    - by upton
    After reading some projects, I find that it is not the architecture of the software that is really hard to know. It is not hard to figure out the architecture immediately if the project is clearly designed and implemented, if it's hard and never seen before, some day later I can find out some pattern similar to the one I read in the same domain. The difficulty is that the concepts and mechanism defined by the author are really hard to guess, and these concepts may spread in the whole project which makes it hard to grasp. The situation is normal and universal and you can ask questions to your colleague when in a company. However, it gets worse if nobody around you knows these details. How do you handle these details which block your reading?

  • Should I Learn C/C++ Even If I Just Want To Do Web Programming?

    - by Daniel
    My goal is to be able to create online apps and dynamic, database driven websites. For instance, if in the future I get the idea for the next Digg or Facebook, I want to be able to code it myself. To arrive there I think I have basically two paths: Path 1 Start at a basic level, learning C, then C++ for OOP, then algorithms and data structures, with the goal of getting a solid grasp of computer programming. Only then move to PHP/MySQL/HTTP and start working on practical programming projects. Path 2 Start directly with PHP/MySQL/HTTP and getting my hands dirty with practical projects right away. What would you guys recommend?

  • Continue with Java for pc or go to android? [on hold]

    - by Chris London
    so I have been learning java from Deitel's learn java 9th edition. I am up to GUI's and a have a pretty good grasp on OOP etc. I want to go straight to the mobile app development scene, I believe I will learn a fair bit there on using API's, and other tools to develop apps. I am not sure weather I should carry on with PC coding (GUI's etc etc) or skip it all and go direct to learning the Android SDK. So, should I carry on, learn about sockets, writing and reading files, GUI's for PC etc or get a book and jump into android? Thanks a lot guys.

  • Is it okay to introduce LESS to not so savvy UI Designers?

    - by Jason Nathan
    I just got a job as lead developer and I thought it would be best to seek the expertise of my peers (that's you) before proceeding! I had the opportunity to review my designers and they are mostly photoshop pros with dreamweaver as their main HTML/CSS editor. A more visual experience. I, on the other hand, have had much experience hand-writing all my code. From HTML markup to CSS. From my understanding, my designers have basic CSS knowledge and I am considering a simple 101 style set of tutorials for them to get a better grasp of markup before I moved into more advanced topics like accessibility and microformat markup. We need to get started up quickly. Do you think it's okay to dive into LESS from the get-go?

  • Studying Quantum Computing?

    - by The_Neo
    Hi I am a computer science student currently on an internship and I have been thinking more and more about looking into working for a company / places that is developing quantum computers/ing when I graduate. Here is my problem, I have a pretty solid grasp of mathematics involved in Comp Sci and enjoy learning about more Comp Sci theory but in doing some minor research about Quantum Computing it seems to me to be more about hardware and I have always leant more to the software side of things. I haven't studied any physics since high school so I am wondering if I would be suitable to work in such a field with a Comp Sci degree, is it a field more aimed at physicists?

  • How to write loosely coupled classes in node.js

    - by lortabac
    I am trying to understand how to design node.js applications, but it seems there is something I can't grasp about asynchronous programming. Let's say my application needs to access a database. In a synchronous environment I would implement a data access class with a read() method, returning an associative array. In node.js, because code is executed asynchronously, this method can't return a value, so, after execution, it will have to "do" something as a side effect. It will then contain at least 1 line of extraneous code which has nothing to do with data access. Multiply this for all methods and all classes and you will very soon have an unmanageable "code soup". What is the proper way to handle this problem? Am I approaching it the wrong way?

  • Android design advice - services & broadcast receivers

    - by basudz
    I'm in the process of learning the Android SDK and creating some projects to get a grasp on the system. The current project I'm working with works just fine but I'd like to get some advice about other ways I can go about designing it. Here's what it needs to do. When a text message is received from a specific number, it should fire off a toast message that repeats at a certain interval for a specific duration. To make this work, I created an SMS BroadcastReceiver and checked the incoming messages for the number I'm looking for. If found, an IntentService would be started that would pull out the interval and duration from saved shared prefs. The IntentService would then fire off a broadcast. The BroadcastReceiver for this would catch it and use the AlarmManager to handle the toast message repetitions. This all works just fine, but I'm wondering if there's a cleaner or more efficient way of going about doing this? Any suggestions or advice?

  • Search and Replace in MVC

    - by danip
    What would be a good MVC/OOP/GRASP/SOLID structure for a search/replace functionality. Methods: search/searchNext/replace/replaceAll. I'm interested only in the PHP arhitecture and how a professional developer would implement this in it's OWN FRAMEWORK. What names would you use for the classes? What subfolders would you used in your MODEL folder? How would you connect the MODELS/CONTROLLER? This is just a arhitecture question to understand better the principles of good OOP in practice. My current implementation is very simplistic using a service model: /controller/SearchReplaceController.php /models/services/SearchReplaceService.php The problem with this is I know I'm breaking SRP in the service but I found this somehow acceptable. Also creating a service does not feel like the best solution for this.

  • Size of an image imported with FreeImage

    - by KaiserJohaan
    I'm having abit of a brainfart and I can't quite grasp what I'm doing wrong. It's quite simple, I am importing an image with FreeImage (http://freeimage.sourceforge.net/) which has a method FreeImage_GetBits that returns a pointer to the first byte of the image data. I then try to load all the data into memory using (bitsperpixel / 8) * pixelsWidth ' pixelHeight, like this: uint32_t bitsPerPixel = FreeImage_GetBPP(bitmap); // resolves to 24 uint32_t widthInPixels = FreeImage_GetWidth(bitmap); // resolves to 1024 uint32_t heightInPixels = FreeImage_GetHeight(bitmap); // resolves to 1024 // container is a std::vector<uint8_t> pkgMaterial.mTextureData.insert(pkgMaterial.mTextureData.begin(), FreeImage_GetBits(bitmap), FreeImage_GetBits(bitmap) + ((bitsPerPixel/8) * widthInPixels * heightInPixels)); I have a jpg which is 31 kilobytes in size on disc. Yet when I load it using the above formula, I see the vector is then filled with 3145728 bytes, which is approx 3145 kilobytes. What am I doing wrong?

  • Settings object with singleton pattern

    - by axis
    I need to build an object that will have only one instance because this Object is dedicated to the storage of vital settings for my application and I would like to avoid a misuse of this type or a conflict at run-time. The most popular solution for this, according to the internet, is the Singleton pattern. But I would like to know about other ideas or solutions for this; also I would like to know if other solutions can be much more easy to grasp for an user of this hypothetical library. Thanks.

  • How the yin-yang puzzle works?

    - by Hrundik
    I'm trying to grasp the semantics of call/cc in Scheme, and the Wikipedia page on continuations shows the yin-yang puzzle as an example: (let* ((yin ((lambda (cc) (display #\@) cc) (call-with-current-continuation (lambda (c) c)))) (yang ((lambda (cc) (display #\*) cc) (call-with-current-continuation (lambda (c) c)))) ) (yin yang)) It should output @\*@\**@\**\*@\**\**@..., but I don't understand why; I'd expect it to output @\*@\**\**\**\**\*... Can somebody explain in detail why the yin-yang puzzle works the way it works?

  • Does Java need closures?

    - by Bill the Lizard
    I've been reading a lot lately about the next release of Java possibly supporting closures. I feel like I have a pretty firm grasp on what closures are, but I can't think of a solid example of how they would make an Object-Oriented language "better". Can anyone give me a specific use-case where a closure would be needed (or even preferred)?

  • Should Competent Programmers be "Mathematically Inclined"

    - by Abhijeet Patel
    From a blog post by Jeff Atwood of the same title, I can tell from personal experience that it's much more easier to grasp math after having worked professionally as a developer for a while. I appreciate math much more as I can see it's real world applicability. Can you recommend any resources/books that can help become familiar and comfortable with the kind of math concepts that developers should be familiar with for being well rounded and effective developers.

  • Eclipse IDE Learning Curve

    - by Vladimir Georgiev
    I am a C# guy with pretty good grasp of Visual Studio IDE usage (using it since VS2003). Right now, I am doing a proof of concept app using Eclipse 3.4.1. Is there any good reference or book which describes the usage of Eclipse IDE, compared to Visual Studio. Is there any Eclipse guide for Visual Studio users :) Thanks, in advance.
