From where should I learn Android which should be easy to grasp and learn for a newcomer like me.

  • Can Google Forms do carriage returns/ line feed

    - by Simon
    I am trying to write a pre-qualification programming exam, hopefully using Google Forms... however they seem to be unable to do new-lines in both the questions and the section headers... My current format is new page for each question, with a "section header" as the main question (because it has a textarea for the "code snippet") and a "multiple choice question" as the ummm... question answer... Help much appreciated...

  • Java Interfaces Methodology

    - by Amir Rachum
    Hi all, I've been programming in Java for a few courses in the University and I have the following question: Is it methodologically accepted that every class should implement an interface? Is it considered bad practice not to do so? Can you describe a situation where it's not a good idea to use interfaces? Thanks.

  • Open plan office annoyance

    - by arturito
    Not a technical question, but related to IT. At the moment I work in the open plan office and the guy next to me is talking to himself while programming. It annoys my collegue and me so much that we are putting the earphones on with music volume set to max. Does anyone know good and polite solution to shut him up?

  • Recursion problem in algorithm

    - by Marthin
    I'm not sure if this is the right place to post this, but the problem actually belongs to a programming assignment. Solve the recursion: T(0) = 2; T(n) = T(n-1) + 2; Solution: T(n) = 2(n+1) Could someone please show me how they got to that solution?

  • Exception throws: encapsulate them or not?

    - by Simon
    Hi there. Once I read an MSDN article that encouraged the following programming paradigm: public class MyClass { public void Method1() { NewCustomException(); } public void Method2() { NewCustomException(); } void NewCustomException() { throw new CustomException("Exception message"); } } Do you think this paradigm makes sense? Wouldn't it be enough to store the exception message in a static const field and then pass it to the exception's constructor, instead of encapsulating the whole exception throw?

    - by Rachel
    I have never worked on ejb, when I started programming Spring was already arrived and all my projects have been with Spring only, recently I had one interview and they wanted knowledge of EJB3.0 and so I want to know how does EJB3.0 stack up with Spring Framework and why many projects now a day are with Spring Framework and not with EJB3.0, do not quote me here as I can be wrong I would really appreciate if difference and benefits of using one over another could be explained from practical perspective.

  • Disabling Remote-Debugging Connection on Windows 2000

    - by Kim Leeper
    I have two machines one running Win 2000 and one running Win XP both with VSC++ 6. I created an application on the Win XP machine (local) and sucessfuly used the Win2000 machine (remote) as the target for debugging. The code was in a shared drive on the Win2000 machine. This setup worked well, just like in the movies! However, I now wish to use my Win2000 machine as a develpment machine again and I find I can not. When attempting to execute a natively compiled application on this machine, I get a dialog with the title of "Remote Execution Path And Filename" asking me for same. When dialog is cancelled as the program that is attemptng to execute is not remote, the program terminates without error. Extra info! On the WinXP machine, VSC++, under the Build menu-Debugger Remote Connection-Remote Connection Dialog-the "Connection:" list box has two entries 'Local' and 'Network', on the Win2000 machine the 'Local' entry is not present, only the entry for 'Network'. How do I get back my 'Local' entry on what used to be my target machine?

  • Best practices for QA / testing in an Agile (Scrum+XP) team?

    - by Srirangan
    Hey guys, We're getting a QA for the first time in our project. We're not sure how to best use him. We work in an Agile environment. Pair programming, user stories, short sprints (two weeks), daily stand-ups, retrospectives, planning meetings, quick releases etc. One obviously way to use a tester is to verify bugs fixes and user stories every sprint. Are there any better ways for an Agile team to utilize a tester. Thanks, Sri

  • Deterministic floating point and .NET

    - by code2code
    How can I guarantee that floating point calculations in a .NET application (say in C#) always produce the same bit-exact result? Especially when using different versions of .NET and running on different platforms (x86 vs x86_64). Inaccuracies of floating point operations do not matter. In Java I'd use strictfp. In C/C++ and other low level languages this problem is essentially solved by accessing the FPU / SSE control registers but that's probably not possible in .NET. Even with control of the FPU control register the JIT of .NET will generate different code on different platforms. Something like HotSpot would be even worse in this case... Why do I need it? I'm thinking about writing a real-time strategy (RTS) game which heavily depends on fast floating point math together with a lock stepped simulation. Essentially I will only transmit user input across the network. This also applies to other games which implement replays by storing the user input. Not an option are: decimals (too slow) fixed point values (too slow and cumbersome when using sqrt, sin, cos, tan, atan...) update state across the network like an FPS: Sending position information for hundreds or a few thousand units is not an option Any ideas?

  • How to build a widget for my website

    - by Gublooo
    Hey guys I'm very new to the whole programming - so far I only have experience with building websites, database etc. I currently have a website where users can share their online purchases. I want to build a widget that other websites can integrate on their site. Users should be able to insert their purchases directly through this widget without having to come to my website. Thats the idea but I have no idea how to go about it - can anyone point me in the right direction. Thanks

  • Client-Side caching on IIS7 doesn't seem to work

    - by thomasbtv
    I have set content caching on a specific folder by following the local web.config method. I don't think it works, and I would like to fix this. I activate the cache using the IIS / HTTP Headers / Common headers feature. I set them to 1 day of expiration. I opened a page with Google Chrome in private navigation, and then open the Network tab in the console. The first time I load the page, everything loads from the site, obviously. If I refresh the page, I see 2 types of loading in the Network console: the files from Google and Facebook and such have a status of 200, and a size of (from cache). the files from the folder for which I set the caching have a status of 304 and their size is displayed. So, I guess the caching setting doesn't work? Or does the 304 response means that it's loaded from the cache? If they aren't, how can I make it work ? Thanks !

  • where can I get these kind of exercises to solve?

    - by flash
    Recently I did a Java programming exercise successfully which was sent by a recruiting firm, The problem statement goes like this 'There are two text files FI(records abt files and directory information) and FS(containing blocks of data) which represent a file Index and file System respectively and I was supposed to write a static read method in a class which will read the file from the FS depending upon the path string provided using FI' My question is where can I get these kind of exercises to solve, the complexity should be above average to tough.

  • Good starting point to learn regular expressions.

    - by Jeremy Rudd
    I'm good at learning new languages and platforms, though whenever I try to learn Reg Ex I cannot make sense of it. I once even used the Regular Expression Designer to try and put some together. What's a good starting point to understanding what looks like the only rocket-science programming language in the world? Links to articles, books or anything else that could help me get my grounding would be appreciated.
