  • Is embedded programming closer to electrical engineering or software development?

    - by Jeremy Heiler
    I am being approached with a job for writing embedded C on micro controllers. At first I would have thought that embedding programming is to low on the software stack for me, but maybe I am thinking about it wrong. Normally I would have shrugged off an opportunity to write embedded code, as I don't consider myself an electrical engineer. Is this a bad assumption? Am I able to write interesting and useful software for embedded systems, or will I kick myself for dropping too low on the software stack? I went to school for computer science and really enjoyed writing a compiler, managing concurrent algorithms, designing data structures, and developing frameworks. However, I am currently employed as a Flex developer, which doesn't scream the interesting things I just described. (I currently deal with issues like: "this check box needs to be 4 pixels to the left" and "this date is formatted wrong".) I appreciate everyone's input. I know I have to make the decision for myself, I just would like some clarification on what it means to be a embedded programmer, and if it fits what I find to be interesting.

  • Why has the accessor methods from the JavaBean specification become the standard for Java development?

    - by Dakotah North
    The JavaBeans Specification describes a JavaBean as A Java Bean is a reusable software component that can be manipulated visually in a builder tool Since the majority of the lines of code that are written seem to have nothing to do with being manipulated visually in a builder tool, why has the JavaBean specification been the "way" to write object oriented code? I would like to forgo the traditional getter/setter in favor of Fluent Interfaces all throughout the code, not just in builders but fear doing so since this is traditionally not the way way object oriented code is written in Java.

  • Native mobile app development - how do I structure my user stories?

    - by richsage
    I'm about to start on a project which will involve developing prototype native mobile apps (iOS and Android initially) as well as a web-based admin interface and an API for these apps to communicate with. We've got a list of stories already drafted up, however a lot of them are in the format: As a mobile user I want to be able to view a login screen so that I can sign into the app If this were targeted for a single platform, I wouldn't see a problem. However, since we're targeting multiple platforms, I'm not sure whether these should now be duplicated eg "As an Android user" or similar. This seems like duplication, but it's work that will need to be completed separately for each platform. This is the first mobile project we've gone native on - previously it was Phonegap and we lumped all stories in under "As a mobile user". Since essentially this was a web-based app wrapped in native code, this didn't present too much of an issue, but I'm conscious that wholly-native apps are a different ballgame!

    - by Ashish Pisey
    I have been developing iOS apps for six months now and every day i find something new and exciting to learn. i feel blessed with apple docs and 3rd party APIs.I have four apps on the App Store.i have tried almost all the basic core features of iOS except core-data. MY recent interests are dynamic UI,physics(sprite kit) and social apps.As i feel lost in vast pool of knowledge,i would like to know from you expert iOS developers, what particular features should i concentrate on for the future? should i try opengl-es for 3d gaming for 64 bit processors or stick to basic 2d physics gaming for some time or the evergreen social apps category ? appreciate your help, thanx

    I'm trying to rip an audio cd from my old library but when I try (with every app) to do that, the process is too slow. For 2 tracks it need more than 2 hour and then it crash!

  • Database development/admin - What exactly should I be trying to learn? [closed]

    - by Sauron
    I've been a bit weary about approaching learning databases. I've dabbled into them before, and "DATA" in itself appeals to me a lot. Maintaining/searching/moving, everything about it in the abstract sense I love. (This isn't a career question, this is a learning question.) But as RDBMS's begin to be easier to maintain, and with tools that "anyone" can use to manage data I feared for the database admin jobs. (Yet I see jobs for SQL everywhere!). I know "No-SQL" was a big deal but it kinda has its niche. But that leaves me here... unsure of really "what" to study. What tools should I have in my tool belt? I'm sure RDBMS's will be around in both use and maintaining legacy code. But what else? Obviously data will always be around, but is this a secure field or a dying one? And what should I be concentrating on?

  • What are the pros and cons of public sector vs private sector software development? [closed]

    - by j.i.h.
    I'm currently considering a job working for my state of residence. However, besides the obvious drawback of far less compensation than I could get in the private sector, are there any other drawbacks? Are there any upsides to public work, besides helping society at large and benefits? My main concern is that if I work in the public sector, I might be stained with the perception that I "got along" in an uncompetitive environment. I have no idea if this would be the actual environment, but it seems to be the preconception about government work--unionized workers who are simply there because the union keeps them from being fired. So, does anyone have experience working for the government? Do you have experiences working with people transitioning from public to private sector?

  • What Role Should SEO Play in the Development of Your Website?

    Most SEO experts will agree that they are mostly called out to do fire extinguishing rather than fire prevention, and in many cases it would have been far better to team up with SEO expertise from the beginning of developing your website than to wait until traffic isn't coming. You need to build your website in cooperation with the SEO expert right from the start.

  • Are there Windows virtual images available for development? [closed]

    - by Nick T
    I want to test deployment of a Windows application and a virtual PC seems the easiest method (I could be wrong, feel free to comment, but the question still stands). Courtesy my Windows 7 I have Virtual PC, and I seem to recall way back in XP I could download a pre-made image for Virtual PC 200x(7?) and use that without having to install from media. Are there any similar images for developers for Virtual PC?

  • What videoconferencing platforms work best for distributed software development teams?

    - by user11347
    Today I had a religious experience: I participated in a videoconference using a high quality Polycom system. This made a huge difference in communication quality -- people that I had a terrible time understanding previously now sounded like Shakespeare. Seeing a high quality video image was enormously helpful. I asked operations how much the Polycom cost and they said that it cost $20K new and $4K off eBay. So this solution doesn't work for people who work from home or who work in offices but are in groups of 3 or fewer people. My budget for a videoconferencing system is a few hundred dollars per person. Skype is not nearly good enough. And I haven't seen a consumer webcam that is good enough either. Does such a solution exist? I'm looking to collaborate both with people who are close by (in the same city but not in the same room) and far away (on different continents).

  • How would you manage development between many Staging branches?

    - by Trip
    We have a Staging Branch. then we came out with a Beta branch for users to move whenever they wanted to from old Production branch to the new features. Our plan seemed simple, we test on Staging, when items get QA'd, they get cherry-picked and deploy to Beta. Here's the problem! A bug will discreetly make its way on to Beta, and since Beta is a production environment, it needs fixes fast and accurate. But not all the QA's got done. Enter Git hell.. So I find a problem on Beta. No sweat, its already been fixed on Staging, but when I go to cherry-pick the item over, Beta barely has any of the other pre-requisites of code to implement this small change. Now Beta has a little here and a little there, and I can't imagine it as a code base being as stable as Staging. What's more, is I'm dealing with some insane Git conflicts, and having to monkey patch a bunch of things to make up for what Beta hasn't caught up with Staging. Can someone polite or non-polite terms, tell me what we're doing wrong here as far as assembling this project? Any awesome recommendations or workarounds or alternatives to the system we came up with?

  • Metro-style / iPhone apps development too demanding for newbie developers? [closed]

    - by linquize
    Both Metro-style and iPhone app require approval and publishing to app store. And they focus most on user interface and the quality of the software. Developers must deal with technical aspects, such as async programming (no UI blocking), no console program (must design a UI that cope with "Standard"), no CPU hungry (pause app if deactivated), need to study the permission matrix (not full access right), and more ... A newbie is not familiar with threading and synchronization. Do you thick they are too demanding for newbie developers? Can you give more examples how demanding it is?

  • Is there such a concept as "pseudo implementation" in software development?

    - by MachuPichu
    I'm looking for a label to describe the practice of using human-based computation methods or other means of "faking" an algorithm for the sake of getting a product or demo off the ground quickly without spending the time to develop an technical/scalable/analytical solution? Eg: using Amazon Turk to count the number of empty tables in a restaurant. I'm also looking to learn more about this subject, but not sure what to search for. Human-based computation is only one method, I'm interested in the general idea of pseudo-implementation. Any ideas, recommended reading? Thanks

  • What is the starting point for Ubuntu app development? [closed]

    - by Roshnal
    I'm thinking of developing software for Ubuntu and other related Linux-based distros (like Linux Mint). But currently am at a loss for where to start. Would learning Python be enough/good? And what are the other things I should know about before starting this kind of developing? And will I be able to publish my apps to a software store like Ubuntu store even if I am from outside USA/UK? If not, what are the options I have to make my apps reach the audience? As a lot of users had asked, I intend to build applications only for Linux (I'm thinking of Gnome) that will be a bit business and enterprise oriented. Currently I am an Oracle certified Java developer in J2SE and J2ME. And I know Python a bit.

  • How to get the stacktrace in a mobile device?

    - by Daniel Moura
    I'm getting a NullPointerException in a Nokia S40. I want to know what is causing this exception. The device shows: NullPointerException java/lang/NullPointerException This error only occurs in the device, running in the emulator the application works fine. I use microlog to debug my application. But the application works fine if the log is enabled. Is there a way to get the stack trace when I get this NullPointerException? I don't need all details like the line number just which method cause this exception. UPDATE: I installed the same application in another Nokia S40 and the same error didn't occur. Nokia 2660 - error Nokia 6131 - no error UPDATE 2: Somehow I find what was causing the NullPointerException. import javax.microedition.lcdui.Canvas; import javax.microedition.lcdui.Graphics; public class OuterClass extends Canvas { private Config config; public OuterClass() { this.config = new Config(); } public void paint(Graphics graphics) { HelperClass helper = new HelperClass(this.config); helper.doStuff(); } public void dispose() { this.config = null; } public class Config implements IConfig { public int getSomething() { // ... } } } public class HelperClass { private IConfig config; public HelperClass(IConfig) { this.config = config; } public doStuff() { config.getSomething(); // Here is thrown NullPointerException } } In some situations a thread is started and call the OuterClass.dispose() before the helper.doStuff() causing the NPE. I think when I enabled the log it made the thread slower and helper.doStuff() was called when I expected it to be called.

  • Programming texts and reference material for my Kindle DX, creating the ultimate reference device?

    - by mwilliams
    (Revisiting this topic with the release of the Kindle DX) Having owned both generation Kindle readers and now getting a Kindle DX; I'm very excited for true PDF handling on an e-ink device! An image of _Why's book on my Kindle (from my iPhone). This gives me a device capable of storing hundreds of thousands of pages that are full text search capable in the form factor of a magazine. What references (preferably PDF to preserve things such as code samples) would you recommend? Ultimately I would like reference material for every modern and applicable programming language (C, C++, Objective-C, Python, Ruby, Java, .NET (C#, Visual Basic, ASP.NET), Erlang, SQL references) as well as general programming texts and frameworks (algorithms, design patterns, theory, Rails, Django, Cocoa, ORMs, etc) and anything else that could be thought of. With so many developers here using such a wide array of languages, as a professional in your particular field, what books or references would you recommend to me for my Kindle? Creative Commons material a plus (translate that to free) as well as the material being in the PDF file format. File size is not an issue. If this turns out to be a success, I will update with a follow-up with a compiled list generated from all of the answers. Thanks for the assistance and contributing! UPDATE I have been using the Kindle DX a lot now for technical books. Check out this blog post I did for high resolution photos of different material: http://www.matthewdavidwilliams.com/2009/06/12/technical-document-pdfs-on-the-kindle-dx/

  • To display the images in mobile devices is it necessary that the images should resides on device in

    - by Shailesh Jaiswal
    I am devloping smart device application in C#. In this application I have some images in my application which I used to dispay on emulator from my application. To display the images on emulator I need to create the one folder of images which resides on the emulator. Only after that I am able to display the images in emulator. I am able to create the folder in emulator by using File-Configure-General-Shared Folder. For sharing the folder I am giving the path of the folder which contains the images. Once I share the folder the folder of images which resides in my application will get copied in emulator with the name "Storage Card". Now I need to use the path as Bitmap bmp=new Bitmap(@"/Storage Card/ImageName.jpg"); Now I am able to display the images in emulator. Can we display the images in the emulator without any image folder which resides on emultor (so that we dont need to place the image folder in emulator as in the above case by sharing the folder) ? If the answere is no then to run the application on different mobile devices we need to place the folder which contains the images on different mobile devices. Isnt it? If the answere is yes then how we can display the images on different mobile device from our application without placing any folder of images on mobile devices?

  • Why there is no open source framework (like Java) for C# application development?

    - by Calvin
    Hi, C# is much more popular than Java in recent years. As a general-purpose programming language, many people feel that C# is better designed than Java. Why until now there is no open source framework for C# application development? Why no one take the initiative to develop a open source framework for C# which is comparable to Java? (Many people say Mono is not a mature framework and should not be used in serious application development.) Calvin
