  • Why does Android make good coding so difficult?

    - by metacircle
    my daily work is writing tools in C#/WPF. After over more than 1 year on the job now, I came to love MVVM, IoC Containers, XAML (and more). It's pure fun to write code, since simple, maintainable and extendable code just comes naturally when you follow a few basic patterns. In my free time I really want to write some apps, mainly for my own personal use. I want to write apps for fun and not to make money or anything, that being said, paying an annual fee to be allowed to use my own apps on my own device is a total no-go for me. So I am not able to code for Windows Phone and am also not able to use Xamarin on Android (which is sad since Visual Studio + Resharper is programmers heaven). So I am stuck with Android "classic" Java development. Everytime I sit down at home to create an app, or improve some of the code I have already written I get annoyed very quick because getting good, decoupled code is just so hard to accomplish. It feels like everything you have to do in Android to create a good architecture is a workaround instead of being the way things are meant to be. Writing the UI in xml is fine, but everything else is one big code mess. Even all the tutorials do all their coding in the code behind. For 'hello world' this is fine, but for anything bigger this gets messy very very quick. This is where the fun for me ends. It's just no fun anymore because I just spend 90% of my time refactoring and thinking of workarounds how to make my code more maintainable with all the restrictions Android puts on me. Am I missing a crucial part or is this just the way Android is meant to be? Do you have any suggestions how to learn 'the fun way' of Android programming.

  • PPT Leveraging Azure for Performance Testing

    - by Tarun Arora
    I have recently presented a session on “How you can leverage Azure for Performance Testing” your application.  It goes without saying that performance testing your application not only gives you the confidence that the application will work under heavy levels of stress but also gives you the ability to test how scalable the architecture of your application is. It is important to know how much is too much for your application! Working with various clients in the industry I have realized that the biggest barrier in Load Testing & Performance Testing adoption is the high infrastructure and administration cost that comes with this phase of testing. In the session I tried to demonstrate how you can use the power of Windows Azure to effectively abstract the administration cost of infrastructure management and lower the total cost of Load & Performance Testing. You can view the session presentation here, http://www.slideshare.net/aroratarun/leveraging-azure-for-performance-testing  I’ll be adding a video on this subject shortly… If you have any feedback or further suggestions to add to the goodness of this solution please get in touch.

  • Virtualbox install 12.04 guest: "pae not present"

    - by Peter.O
    I get this message while trying to install Ubuntu 12.04 as a guest in VirutalBox 4.1.18, on an Ubuntu 10.04 host. This kernel requires the following feature not present on the CPU: pae Some host specs: The host's kernel is: Linux 2.6.32-41-generic-pae GNU/Linux lscpu (host): Architecture: i686, CPU op-mode(s): 32-bit, 64-bit grep --color=always -i PAE /proc/cpuinfo   does show pae in its output. The 12.04 iso used is: ubuntu-12.04.0-desktop-i386.iso As a comparison/check, I downloaded and installed Linux Mint 13 Cinnamon to the same host on the exact same VM (I just changed the .iso image). It worked fine. Its iso is: linuxmint-13-cinnamon-dvd-32bit.iso It seems (to me) that I have pae.. what is going on here? Update: I had assumed that Linux Mint also required pae (being Ubuntu based), but I've just run;   grep --color=always -i PAE /proc/cpuinfo   in the Mint VM.   It showed no output.   So it seems the issue may lie with VirtualBox.   If that is the case, how can I get Virtualbox into pae mode?

  • How to justify rewriting/revamping legacy software in a business case?

    - by sxthomson
    I work for a great little software company which makes good revenue from our main software package. The problem for me is that it's almost unmaintainable. It's written in Delphi 7 (has upgraded versions over time) and has been worked on by a lot of developers over the past 20 or so years. The software lacks any meaningful architecture - there's no object orientation whatsoever, horrible amounts of cyclical dependencies and an over-reliance on global variables to name just a few things. Another huge thing for me is Delphi 7 does NOT support 64-bit. The problem here for me is that my management team don't care about technical things, they want to know why they should care. Obviously that's expected, so what I'm asking here is for some guidance, or tales, or pitfalls about this kind of thing. There's a few things I would love to include, namely for me, the length of time taken to debug/write a feature in "legacy" code, versus coherent, well structured OO code. Does anyone know of any blog posts or the like where this is talked about? For us in the company this is a huge reason. Despite being decent developers we feel like writing a new feature is just piling more rubbish on top. On top of that, even for me who has a decent level of understanding of the code, changing things is infuriating - a small change can have a ridiculous domino effect. Anyone have any experiences they'd like to share?

  • Audio comes out of both headphone and speaker at the same time.. Ubuntu 12.04LTS [closed]

    - by pst007x
    I have the same issue on an Aspire. Ubuntu 12.04LTS 64bit realtek audio sound chip onboard If I plug in a headset, audio does not switch from internal speaker to headset, instead plays out of both at the same time.

  • 25 years old and considering a career change...possible? practical?

    - by mq330
    Hi all, I'm new to this site and new to programming as well. I've spent some time going through an intro cs book that uses python as the language of choice. I find the exercises interesting and engaging and I generally have had a favorable experience programming so far. I've gone through some of the basics with python like writing simple programs, basics of GUIs, manipulating strings, lists, defining functions, etc. And I've always loved technology. Although I've never done any real hardcore programming yet, I was inclined to building websites from a very young age but I never really developed my skills. Now, the thing is I'm 25, I have my bacholors in environmental studies and two masters degrees in urban planning and landscape architecture respectively. I know, it would be quite a departure to pursue a career in programming at this point. Currently, I'm working as a geographic information systems intern. I've taken some GIS classes and have a lot of experience with making maps, doing spatial analysis etc. So what I'm thinking is maybe I can learn some solid programming skills and apply these skills in the field of GIS. From what I've seen, .net languages are the norm in this arena. Could you perhaps provide some guidance to me in terms of what languages I should focus on or courses I should take at this point? What about for building web mapping applications? Also, I was thinking about getting a certificate in programming from a university extension program. Do you think it would be worth it? And furthermore, do you think potential employers would be interested in hiring someone like me (once I get a couple of languages down pretty well) as an intern or in an entry level position? I'll be living in the bay area so I feel that there should be decent opportunities even though I don't have a b.s. in cs.

  • Is there a NVIDIA driver (for a 7-series card) that will actually work for 12.10?

    - by DS13
    I see many similar topics on this, but I've tried all their suggestions, and nothing has worked. ISSUE: I do a clean install of Ubuntu 12.10. Boots fine with the “nouveau” graphics driver – graphics are very slow and choppy. The three other driver options in Ubuntu (official NVIDIA drivers), all result in a variation of the black screen on boot up. There will be NO access to a command line/GUI in anyway what-so-ever (tried every option recommended out there, but the system is unusable at this stage). I can only reinstall, and try different drivers…and I only ever get one shot at it. QUESTIONS: Does anyone know of a NVIDIA driver that will actually work with a Nvidia GeForce 7350LE? Or a 7-series card in general? This is my second computer, and I’m just trying to get a working install of Ubuntu on it. I don’t want to put much money into it, as I have seen Ubuntu run great on much older/less capable machines. I’ve got a decent Intel processor (2.3Ghz), 2GB of RAM, 320GB hard drive, 32-bit architecture, and there is no other O/S installed. It appears as if the graphics card is holding me back. Should I just buy a cheap graphics card (non-NVIDIA) to put in as a replacement? TRIED SO FAR: -all drivers available in Ubuntu *all fail -manual install of some different NVIDIA drivers *all fail -also tried installing the generic kernel, Nvidia driver doesn't work in 12.10 *no difference -every method suggested to at least get a command line after switching to a NVIDIA driver *all fail

  • Are specific types still necessary?

    - by MKO
    One thing that occurred to me the other day, are specific types still necessary or a legacy that is holding us back. What I mean is: do we really need short, int, long, bigint etc etc. I understand the reasoning, variables/objects are kept in memory, memory needs to be allocated and therefore we need to know how big a variable can be. But really, shouldn't a modern programming language be able to handle "adaptive types", ie, if something is only ever allocated in the shortint range it uses fewer bytes, and if something is suddenly allocated a very big number the memory is allocated accordinly for that particular instance. Float, real and double's are a bit trickier since the type depends on what precision you need. Strings should however be able to take upp less memory in many instances (in .Net) where mostly ascii is used buth strings always take up double the memory because of unicode encoding. One argument for specific types might be that it's part of the specification, ie for example a variable should not be able to be bigger than a certain value so we set it to shortint. But why not have type constraints instead? It would be much more flexible and powerful to be able to set permissible ranges and values on variables (and properties). I realize the immense problem in revamping the type architecture since it's so tightly integrated with underlying hardware and things like serialization might become tricky indeed. But from a programming perspective it should be great no?

  • Packaging MATLAB (or, more generally, a large binary, proprietary piece of software)

    - by nfirvine
    I'm trying to package MATLAB for internal distribution, but this could apply to any piece of software with the same architecture. In fact, I'm packaging multiple releases of MATLAB to be installed concurrently. Key things Very large installation size (~4 GB) Composed of a core, and several plugins (toolboxes) Initially, I created a single "source" package (matlab2011b) that builds several .debs (mainly matlab2011b-core and matlab2011b-toolbox-* for each toolbox). The control file is just the standard all: dh $@ There is no Makefile; only copying files. I use a number of debian/*.install files to specify files to copy from a copy of an installation to /usr/lib/. The problem is, every time I build the thing (say, to make a correction to the core package), it recopies every file listed in the *.install file to e.g debian/$packagename/usr/ (the build phase), and then has to bundle that into a .deb file. It takes a long time, on the order of hours, and is doing a lot of extra work. So my questions are: Can you make dh_install do a hardlink copy (like cp -l) to save time? (AFAICT from the man page, no.) Maybe I should just get it to do this in the Makefile? (That's gonna b e big Makefile.) Can you make debuild only rebuild .debs that need rebuilding? Or specify which .debs to rebuild? Is my approach completely stupid? Should I break each of the toolboxes into its own source package too? (I'll have to do some silly templating or something, because there's hundreds of them. :/)

  • Help Decide between C#/XNA client or Java

    - by Sparkky
    The game runs on a client/server architecture currently setup for TCP, and the client code was built in AS3 to be web based. What we're running into is 3 problems for the client. AS3 has no hardware acceleration so we are having some issues with slowdown when implementing some features TCP is really frustrating for a sidescroller when you're talking with a server. I'm having a heck of a time with the interpolation/extrapolation to make everyone else look smooth while minimizing lag. I would much rather be able to use UDP and throw in something similar to the age old Quake interpolation/extrapolation. No right click I work professionally with C#, and I did all my University (almost 2 years ago) with Java. Java really appeals to me because of the compatability while C# appeals to me because I've heard so much good about XNA and I love visual studio. For a Client/Server based MMOish sidescroller in your opinion should I stick with AS3 and the TCP protocol, or should I abandon some of my audience, ramp up the graphics and hit C#, or journey back to the land of Java. Thanks :D

  • How can I get a gnome environment in my VNC session?

    - by adante
    When I start VNC I have an empty desktop without the ability to manage windows or start apps etc). I'd like to have a desktop environment to be able to basic desktop things (someone asked me why I wanted this - I can't really say except that I would like my computer to be useful). My focus at the moment is basically having a working environment with as little time/effort expenditure as possible, as opposed to spending a full-time week learning the most trivial and arcane details of x, vnc, gnome or whatever passes for the current desktop architecture standard of the hour. What command or series of hoops do I have to jump to to achieve this? I have tried running gnome-session but it looks like it is attempting to run compiz and fails spectacularly. I've also tried running metacity but this simply gives me a titlebars to my windows (this is great! But I'd also like the taskbar and other stuff). I considered trying to start gnome-session in a way that it uses metacity instead of compiz. But I don't know how to do this. Tutorials on the net exist for changing to metacity - once you already have compiz running. Not so useful if compiz does not run.

  • Should this code/logic be included in Business Objects class or a separate class?

    - by aspdotnetuser
    I have created a small application which has a three tier architecture and I have business object classes to represent entities such as User, Orders, UserType etc. In these classes I have methods that are executed when the Constuctor method of, for example, User is called. These methods perform calculations and generate details that setup data for attributes that are part of each User object. Here is the structure for the project in Visual Studio: Here is some code from the business object class User.cs: Public Class User { public string Name { get; set; } public int RandomNumber { get; set; } etc public User { Name = GetName(); RandomNumber = GetRandomNumber(); } public string GetName() { .... return name; } public int GetRandomNumber() { ... return randomNumber; } } Should this logic be included in the Business Object classes or should it be included in a Utilities class of some kind? Or in the business rules?

  • Why have we got so many Linux distributions? [closed]

    - by nebukadnezzar
    Pointed to from an answer to another question, I came across this graphic, and I'm shocked how many linux distributions currently exist. However, it seems that most of these distributions are forks of already popular distributions with minimal changes, usually limited to themes, wallpapers and buttons. It would still seem easier to create a sub-distribution with the required changes, such as XUbuntu with XFCE4, KUbuntu with KDE4, Fluxbuntu with Fluxbox, etc. In my mind there are a number of problems with having so many distributions - perhaps less security/stability due to smaller group of developers, and also the confusingly vast range of choice for newcomers to Linux. Some reasons that developers might decide to fork are: Specializing on a particular topic (work-related topic - i.e. for a Hospital, etc) An exceptional architecture, that requires a special set of software Use of non-FOSS, proprietary technology, and such So what other reasons are there that have caused so many people decided to create their own distributions? What are the thought processes that have led to this? And are these "valid" reasons - do we need so many distributions? If you can back your experiences up with references that would be great.

  • Optimising news fetching

    - by aceBox
    I have a web scraper for scraping news from different sources in wp7. My current appraoch for doing this is: load newspapers information from xml file. go to the specified sections and fetch the urls of the news items. go to each url and fetch headline, image, publisher. display using a MVVM architecture of windows phone. The whole thing takes place asynchronously...meaning as soon as url from a section of a newspaper is fetched it is added to the queue, and the second stage consisting of fetching headline, image etc starts... and as soon this is fetched even for one article, it is displayed. Later on as more articles are fetched, they are added on to the list. For the fetching purpose I am using a SmartThreadPool(http://www.codeproject.com/Articles/7933/Smart-Thread-Pool) for windows phone. My problem is that...even for fetching around 80 items (in total) from 9 publications, it is taking more than a minute. How can i speed up the procedure? Note: I have a two stage approach because many times the images are not available with headlines, and are only found in the article.

  • How much a programmer should read in order to keep himself updated? [closed]

    - by anything
    There are lots of technical books available. Below are few links which lists some good books If you could only have one programming related book on your bookshelf what would it be and why? What non-programming books should a programmer read to help develop programming/thinking skills? Best books on the theory and practice of software architecture? http://stackoverflow.com/questions/1711/what-is-the-single-most-influential-book-every-programmer-should-read ... and the list can go on and on and on. It will be really difficult to read all of the above mentioned books. I am not sure if its even possible for anyone to do that. Even if you filter it based on one's area of interest or work, list is still very large. .. and the technology keeps on changing (even more books :-( ) So, my question is how much a programmer should read lets say per year? How much hours one should put in such activities to keep oneself up to date? How do we find out the time required? PS: Average programmer reads less than one book per year (Code complete). What about the good programmers?

  • Installation questions

    - by user12609425
    I've gotten a couple more questions about the installation process for Ops Center. "Can I install on any SPARC / X86 based platform?" Ops Center can run on Oracle Solaris on either architecture, or on Linux. The Certified Systems Matrix lists the supported OSes, and the Linux and Solaris install guides go into more detail about the hardware and OS requirements. "Can we install it on local zones or LDOMS?" Zones, yes; LDOMS, sort of. You can install the Enterprise Controller in a local zone. There are a few caveats, which are explained in the Preparing a Non-Global Zone section. You can also install a Proxy Controller in an Oracle Solaris 11 zone. Agent Controllers, which are the part of the infrastructure that's installed on managed systems, can be put on zones or LDOMS. "Do we need any dedicated network ports from all agent monitoring systems?"  Yes. The port requirements are covered in the Network Port Requirements and Protocols table, which is in the feature reference guide as well as in the install guides.
