  • Is programming too easy if compared to other fields?

    - by Shashank jain
    I have been programming since some years and I won't say its a piece of cake but in this field, you know how to do things. You can always google up resources, tutorials. There are tons of already written code to help you with - frameworks, libraries but if you compare it to other innovation fields like "Electronics". Its not too easy to get started with, the community might not be too large on the internet, getting the things right plus lets not forget there is nothing to tell you where the error might be. I have wanted many times but not be able to get into, like, building some kind of robot because I don't know how to start. So my question is that, does programming tends to be easy compared rest of the fields or is it just my intrest that makes it easy?

  • Learning Zend Framework 1 or 2?

    - by ehijon
    I have programmed for a few years in php and now I'm going to learn zend framwork. Zend is very popular and there are a lot of tutorials, books and documentation out there. But I saw in the last months that there is a second version of Zend, but it's not so used and popular, not yet. I think it is better to start with a new version, but I don't know what to do now, as when I see job offers many people require the first version. Which version do you suggest me?

  • Flash Webcam non responsive

    - by powerbuoy
    I've got the same problem as this gentleman: https://answers.launchpad.net/ubuntu/+source/flashplugin-nonfree/+question/176541 Where the webcam settings / access does not work at all / is completely unresponsive in Ubuntu 11.10. I've tried webcam access in Facebook, Google+, my own code + a number of tutorials/demos and none work. What happens is the settings dialogue is completely unresponsive. Clicking tabs or buttons does nothing. In the question linked to a suggested answer is to run Unity 2D. Unfortunately this does not work for me (the exact same thing happens). I've also tried Gnome 3 which also does not work. Note that it is only the webcam settings that don't work. YouTube videos and annoying banners work just fine. Does anyone know of a workaround for this (except going back to 11.04) or if they've fixed this in 12.04? - also, are any of you experiencing the same thing?

  • Rel = translation

    - by Tom Gullen
    I can't find much online about rel="translation" We have tutorials and manual entries which we are going to get users to translate. If the original page in English is: http://www.scirra.com/tutorial/start And there are two translations: http://www.scirra.com/tutorial/es/start (spanish) http://www.scirra.com/tutorial/de/start (german) How would I correctly link all these up? I'm aware at the top of the page I would need to specify the correct IS639-1 code: <html lang="de"> But I'm more interested in letting Google know they are not duplicates but are translated.

  • How to Get Myself Up to Speed in Building a Java Web App

    - by Damian Wells
    I'm a new developer at a fairly large company and I'm working on a Java Web Application with a senior developer there. The Web App is built on top of an IBM stack (RAD, DB2, WebSphere) and basically uses JSPs and Servlets. The Web App is an internal tool to be used by employees to manage data coming from Excel files. So, there are lots of database interaction going around like SQL commands. My question is: I don't know much about JavaEE as a whole and only know a little about JSPs and Servlets and I would like to get myself up to speed so I can understand and contribute to the Web App as fast as I could. What resources (tutorials, links, etc) should I be looking at? Am I supposed to get a book about JavaEE or something that focuses just on JSPs and Servlets?

  • Good resources for 2.5D and rendering walls, floors, and sprites

    - by Aidan Mueller
    I'm curious as to how games like Prelude of the chambered handle graphics. If you play for a bit you will see what I mean. It made me wonder how it works. (it is open-source so you can get the source on This page) I did find a few tutorials but I couldn't undertand some of the stuff but it did help with some things. However, I don't like doing things I don't understand. Does anyone know of any good sites for this kind of 2.5D? Any help is appreciated. After all I've been googling all day. Thanks :)

  • Unit testing - getting started

    - by higgenkreuz
    I am just getting started with unit testing but I am not sure if I really understand the point of it all. I read tutorials and books on it all, but I just have two quick questions: I thought the purpose of unit testing is to test code we actually wrote. However, to me it seems that in order to just be able to run the test, we have to alter the original code, at which point we are not really testing the code we wrote but rather the code we wrote for testing. Most of our codes rely on external sources. Upon refactoring our code however, even it would break the original code, our tests still would run just fine, since the external sources are just muck-ups inside our test cases. Doesn't it defeat the purpose of unit testing? Sorry if I sound dumb here, but I thought someone could enlighten me a bit. Thanks in advance.

  • How to install a Lexmark z600 series printer?

    - by Uri Herrera
    It has been a headache trying to install this printer. All the tutorials I found are for older versions of Ubuntu, and none of them work. How can I install this printer? Edit: HOWTO: Install PITA Lexmark Z600 Z615 and Dell Photo Printer 720 Setup Lexmark Z600 and X series printer on Ubuntu (i tried this one, only that it was translated to spanish, but it was the same instructions) HOWTO: Lexmark Printers I always get an error when extracting the converted tars with all of the tuts, invalid argument or the file doesn't exist. Looks like, i was missing some ia32 libs .. and that caused the errors with the tar files, anyways i still can't print now i get this, cups-insecure-filter How to install Lezmark Z600 series printer Here, the OP offers 2 debs, i installed them on a 32 bit Ubuntu install, now the printer gets recognized but still can't print, 'cause i'm missing a filter, "rastertoz600".

  • How do I make the jump from developing for Android to Windows Phone 7?

    - by Rob S.
    I'm planning on making the jump over from developing apps for Android to developing apps for Windows Phone 7 as well. For starters, I figured I would port over my simplest app. The code itself isn't much of a problem as the transition from Java to C# isn't that bad. If anything, this transition is actually easier than I expected. What is troublesome is switching SDKs. I've already compiled some basic Windows Phone 7 apps and ran through some tutorials but I'm still feeling a bit lost. For example, I'm not sure what the equivalent of a ScrollView on Android would be on Windows Phone 7. So does anyone have any advice or any resources they can offer me to help me make this transition? Additionally, any comments on the Windows Phone 7 app market (especially in comparison to the Android market) would also be greatly appreciated. Thank you very much in advance for your time.

  • Should I be paid for time spent learning a framework?

    - by nate-bit
    To give light to the situation: I am currently one of two programmers working in a small startup software company. Part of my job requires me to learn a Web development framework that I am not currently familiar with. I get paid by the hour. So the question is: Is it wholly ethical to spend multiple hours of the day reading through documentation and tutorials and be paid for this time where I am not actively developing for our product? Or should the bulk of this learning be done at home, or otherwise off hours, to allow for more full-on development of our application during the work day?

  • How do I grok NHibernate's QueryOver API?

    - by Brant Bobby
    I've run into the limits of what NHibernate 3.0's LINQ provider is capable of and decided it's time to learn about one of the more powerful (or at least feature-complete) options: the QueryOver API. The problem is, I have zero experience with ICriteria, and all of the tutorials I've been able to find online either: Assume I'm an ICriteria expert and simply show me how to convert ICriteria code to the new fluent interface, or Are trivial "here's how you do an inner join" examples that don't really help me understand more complex concepts like projections, subqueries, requirements, or whatever other magic the API is capable of. What should I read to really learn about QueryOver, and how to make full use of it?

  • I can't get suspend, hibernate and shutdown to work in Ubuntu 12.04

    - by Fostext
    I recently built a computer with these specs: Asus Motherboard, Intel i3 3.3 GHz dual processor, 8 GB of RAM. I installed 12.04 on a brand new hard drive. I partitioned the hard drive between root, home and swap like I have often read how to do. I cannot get this machine to properly shutdown. I have to hold the power button down now. Although, for the first few days it properly shutdown. I also cannot get the system to hibernate or suspend properly. I have read tons on this and watched many YouTube tutorials on how to fix both, but the computer never wakes up after suspend or hibernate. It just stays on a black screen. Can anyone help? I love 12.04 so far, but these setbacks are making me worried about stability and power management issues. Also, I wonder if it's really bad for the hard drive to force the CPU to shutdown.

  • What makes for a good JIRA workflow with a software development team?

    - by Hari Seldon
    I am migrating my team from a snarl of poorly managed excel documents, individual checklists, and personal emails to manage our application issues and development tasks to a new JIRA project. My team and I are new to JIRA (and issue tracking software in general). My team is skeptical of the transition at best, so I am also trying not to scare them off by introducing something overly complex at the start. I understand one of JIRA's strengths to be the customized workflows that can be created for a project. I've looked over the JIRA documentation and a number of tutorials, and am comfortable with the how in creating workflows, but I need some contextual What to go along with it. What makes a particular workflow work well? What does a poorly designed workflow look like? What are the benefits/drawbacks of a strict workflow with very specific states and transitions to a looser workflow, with fewer, broader defined states and transitions

  • Software development magazines [closed]

    - by Sebastian
    Ive spent the last hour or so browsing the web for professional development magazines. I am mostly interested in the java platform, agile methods, "programming in general" (tutorials on languages or whatever, "hot new stuff" etc) and software craftmanship. My best finding yet was pragpub and maybe MSDN magazine. I am willing to pay and have a Zinio account if anyone knows a magazine about programming that is distributed by them. Ive already browsed a couple of related threads here on stackexchange. ACM and IEEE does not seem relevant, as Im not interested in research articles. Maybe conferences like OOPSLA as somebody mentioned in another thread. PS. I prefer if they are in pdf or readable on kindle or a tablet. DS. BR Sebastian

  • Moving AI in a multiplayer game

    - by Smallbro
    I've been programming a multiplayer game and its coming together very nicely. It uses both TCP and UDP (UDP for movement and TCP for just about everything else). What I was wondering was how I would go about sending multiple moving AI without much lag. At first I used TCP for everything and it was very slow when people moved. I'm currently using a butchered version of this http://corvstudios.com/tutorials/udpMultiplayer.php for my movement system and I'm wondering what the best method of sending AI movements is. By movements I mean the AI chooses left/right/up/down and the player can see this happening. Thanks.

  • Ideas for making money off a website

    - by bradenkeith
    I'm considering acquiring a website that traffics close to 20k a month. It's currently unprofitable, but obviously I would need to change that to justify the cost. It's a support site for a framework similar to CakePHP. A resource that allows people to find plugins for that site. How would you go about expanding this site so that it would be broad enough to raise traffic and how would you make money off of it? Some ideas I've had: 1- BuySellAds.com seem to make ads classy and relevant 2- Team up with other sites in some way (What ways? ... Ecommerce sites that sell plugins (like CodeCanyon), etc) 3- Write tutorials and such to drive more traffic (time consuming, and already heavily saturated for this framework). Are there resources out there that help webmasters in ways like this?

  • How can I easily create cloud texture maps?

    - by EdwardTeach
    I am making 3d planets in my game; these will be viewed as "globes". Some of them will need cloud layers. I looked at various Blender tutorials for creating "earth", and for their cloud layers they use earth cloud maps from NASA. However I will be creating a fictional universe with many procedurally-generated planets. So I would like to use many variations. I'm hoping there's a way to procedurally generate cloud maps such as the NASA link. I will also need to create gas giants, so I will also need other kinds of cloud texture maps. If that is too difficult, I could fall back to creating several variations of cloud maps. For example, 3 for earth-like, 3 for gas giants, etc. So how do I statically create or programmatically generate such cloud maps?
