  • New to Linux Kernel/Driver development...

    - by CVS-2600Hertz-wordpress-com
    Recently, i began developing a driver of an embedded device running linux. Until now i have only read about linux internals. Having no prior experience in driver devlopment, i am finding it a tad difficult to land my first step. I have downloaded the kernel source-code (v2.6.32). I have read (skimped) Linux Device Drivers (3e) I read a few related posts here on StackOverflow. I understand that linux has a "monolithic" approach. I have built kernel (included existing driver in menuconfig etc.) I know the basics of kconfig and makefile files so that should not be a problem. Can someone describe the structure (i.e. the inter-links) of the various folders in the kernel-source code. In other words given a source-code file, which other files would it refer to for related code (The "#include"-s provide a partial idea) Could someone please help me in getting a better idea? Any help will be greatly appreciated Thank You.

  • Alternatives to Java for Android development?

    - by paul.meier
    Hey all, I've started developing Android apps a couple of months ago, and have a few under my belt. While I can tolerate Java enough to keep developing, I was wondering what success the community has had getting other languages to run. I've done some investigation as to how other JVM languages work, and it appears Dalvik messes them up pretty hard. Clojure seems unable to run, Scala seems to be one of the most successful. JRuby has also had some luck, but they caution against anything major. I've also checked out Scheme via Moby and Kawa, both of which seem to have some promise. What luck have any of you had? Languages I'm missing, misrepresenting? Any non-"Hello World" apps you've written in non-Java? Any snags in trying to get another language to run (e.g. "as long as you don't use continuations, you're fine in X Scheme"). Any particular snags in developing apps non-Java, once you get them to run? Thanks, hope you well ^_^

  • How to trigger a Symbian C++ application within a J2ME application for Nokia phones using J2ME API?

    - by kennykee
    Hi all, Anyone knows how to trigger a Symbian C++ application using any J2ME API call? I have a J2ME application that needs a customized photo taking application in Symbian C++. The reason for separating into two applications is because J2ME has a limit in heap size and the J2ME needs to know the path of photo after taking it. Thanks a lot for your help. Regards, Kenny

  • Haars Cascade for Actionscript development

    - by Andre
    Hi guys, I have an object that I want to be able to recognize in AS3. There's a port of OpenCV for AS3 already, that works with Haars cascades, so now I need to create a cascade of my object. From what I've read, I'll have to create an XML of several images (positive and negative), but I can't find a program that'll do that for Mac OS X. Is there anything I can use that'll generate that XML on Mac OS X? Cheers, Andre

  • Apache httpd.conf handle multiple domains to run the same application

    - by John Stewart
    So what we are looking for is the ability to do the following: We have an application that can load certain settings based on the domain that it is being accessed from. So if you come from xyz.com we show a different logo and if you come from abc.com we show a different logo. The code is the same, running from same server just detects the domain on the run Now we want to get a dedicated server (any suggestions?) that will enable us to point all the doamins that we want to this server (we change the DNS for the domains to that of our server) and then when the user goes to a certain domain they run the same application. Now as far as I can understand we will need to create a "VirtualHost" in apache to handle this. Can we create a wildcard virtualhost that catches all the domains? I am not an expert with Apache at all. So please forgive if this comes out to be a silly question. Any detailed help would be great. Thanks

    Hi, I'm trying to set up my developing environment using Visual Studio 2008 to develop for the UNO-1019. I managed to connect the UNO to VS for deployment and debug using the ethernet connection. I installed the SDK for EVC++ available on the products page and I was wondering if I can use that sdk on visual studio 2008.I'm rather new with this and I's kind of lost. Thanks in advance

  • Application Compatibility Clients do not show in MSSQL database, but do show in \AppCompat\

    - by rjt
    Application Compatibility Clients are not denied access to the central MSSQL database, but are able to leave their own files in the \AppCompat\ share. The only computer that shows up in the "Microsoft Application Compatibility Manager" database is the the machine i initially created the .MSI installer from. The MSI successfullly pushed out via GPO and like i said there are tons of file in the \AppCompat\ share from many different computers. But only 1 pc shows up in the "Data Collection Manager" database, so i only have data from one machine. i could manually add all these machines (ADNETBIOSNAME\MACHINENAME221$) to the MSSQL AppCompat db permissions list or use an SQL command to do so in batch, but i suspect i must have missed something. Do you manually edit the MSI to set the credentials?

  • WSS Web application and IIS Website differences

    - by chaitanya
    Can somebody explain briefly the differences between a "WSS Web Application" and a normal "IIS Website"? I have read that a WSS web application is a "special" IIS Website with WSS featured. I also know that the content of a web application is stored in an SQL Server Website(called the content database) whereas an IIS Website stores it on a hard disk on the server. A point-by-point difference would be appreciated.

  • PhysX for massive performance via GPU ?

    - by devdude
    I recently compared some of the physics engine out there for simulation and game development. Some are free, some are opensource, some are commercial (1 is even very commercial $$$$). Havok, Ode, Newton (aka oxNewton), Bullet, PhysX and "raw" build-in physics in some 3D engines. At some stage I came to conclusion or question: Why should I use anything but NVidia PhysX if I can make use of its amazing performance (if I need it) due to GPU processing ? With future NVidia cards I can expect further improvement independent of the regular CPU generation steps. The SDK is free and it is available for Linux as well. Of course it is a bit of vendor lock-in and it is not opensource. Whats your view or experience ? If you would start right now with development, would you agree with the above ? cheers

  • Opera Mobile, offline web app development, and memory

    - by Jake Krohn
    I'm developing a data collection app for use on a HP iPAQ 211. I'm doing it as an offline web app (go with what you know) using Opera Mobile 9.7 and Google Gears. Being it is an offline app, it is very dependent on Javascript for much of its behavior. I'm using the LocalServer, Database, and Geolocation components of Gears, as well as the JQuery core and a couple of plugins for form validation and other usability tweaks (no jQuery UI). I've tried to be conservative with my programming style and free up or close resources whenever possible, but Opera just slowly dies after about 10-20 minutes of use. The Javascript engine stops responding, pages only half-load, and eventually stop loading completely. I'm guessing it's a resource issue. Quitting and relaunching the browser solves the problem, but only temporarily. The iPAQ ships with 128 MB of RAM, about 85-87 MB of which is available immediately after a reset. With only Opera running, there still remains about 50 MB that is left unused. My questions are thus: Is it possible to get Opera to address this unused RAM? Are there configuration settings in Opera or in the Windows Registry itself that will help improve performance? I know where to tweak, but the descriptions of the opera:config variables that I've found are less than helpful. Is is laughable to ask about memory management and jQuery in the same sentence? If not, does anyone have any suggestions? Finally, are my plans too ambitious, given the platform I have to work with? I know that Gears and Windows Mobile 6 are on their way out, but they (theoretically) suffice for what I need to do. I could ditch them in favor of an iPhone/iPod Touch, Mobile Safari, and HTML5 but I'd like to try to make this work first. I didn't think that Opera was a dog when it comes to JS performance, but perhaps it's worse than I thought. That this motley collection of technologies works at all is a minor miracle, but it needs to be faster and more stable. I appreciate any suggestions.

  • Looking for a simple interface for users to enter data for Silverlight application

    - by Edward Tanguay
    I have made a Silverlight application which can read data from various URLs. So users of the application who control a website can: FTP text and XML files onto their website put a clientaccesspolicy.xml in their root directory enter their URL in the silverlight application at which point the silverlight application then begins reading data from their site. I would like to extend this to less technical users who do not control a website, aren't adept with FTP, etc. What is the best service on the web that: allows users to publish different kinds of data, e.g. put out text files on web allows Silverlight client access (has clientaccesspolicy.xml set up) Some ideas are: free blog services (although then they are limited to a RSS feed, or the silverlight app would have to do some screen scraping) Google Docs? free cloud services? What free services allow easy publishing of any kind of data on the web and allow Silverlight client access?

  • Can any Palm Pre be used for development?

    - by teedyay
    We're about to start developing software for the Palm, using WebOS. Though an emulator is available for testing, I always feel more confident seeing it run on a physical device as well. I can't find anywhere on Palm's website that tells me whether I can just buy an off-the-shelf Palm Pre and run my app on it, or if I have to buy one with a particular type of contract/ have it unlocked in some way/ whatever. Does anyone know? Have you done this? (Sorry this is barely programming-related, but I couldn't think where else to ask. I'm sure someone has done this and can give me a quick yay or nay. Thanks.) Oh - I'm in the UK, if that makes any difference.

  • ClickOnce application configured to perform updates programmatically still sometimes displays the Cl

    - by Tom Hall
    We have a WPF application deployed using ClickOnce which checks for and performs updates programmatically on application startup. This generally behaves perfectly except for the case where the user chooses "No" to our "Do you wish to update?" prompt. In this case, the next time the user launches the application (consistently) the ClickOnce framework's "Update Available" dialog launches with the option to update or skip. This doesn't cause a technical problem but will be confusing to the user to potentially see two completely differently styled dialogs. (If the user chooses Skip to the ClickOnce dialog then the application then launches and renders our own "Update Available" dialog). Any ideas why the ClickOnce framework dialog is showing in this case? Thanks.

  • BackgroundWorker From ASP.Net Application

    - by Kevin
    We have an ASP.Net application that provides administrators to work with and perform operations on large sets of records. For example, we have a "Polish Data" task that an administrator can perform to clean up data for a record (e.g. reformat phone numbers, social security numbers, etc.) When performed on a small number of records, the task completes relatively quickly. However, when a user performs the task on a larger set of records, the task may take several minutes or longer to complete. So, we want to implement these kinds of tasks using some kind of asynchronous pattern. For example, we want to be able to launch the task, and then use AJAX polling to provide a progress bar and status information. I have been looking into using the BackgroundWorker class, but I have read some things online that make me pause. I would love to get some additional advice on this. For example, I understand that the BackgroundWorker will actually use the thread pool from the current application. In my case, the application is an ASP.Net web site. I have read that this can be a problem because when the application recycles, the background workers will be terminated. Some of the jobs I mentioned above may take 3 minutes, but others may take a few hours. Also, we may have several hundred administrators all performing similar operations during the day. Will the ASP.Net application thread pool be able to handle all of these background jobs efficiently while still performing it's normal request processing? So, I am trying to determine if using the BackgroundWorker class and approach is right for our needs. Should I be looking at an alternative approach? Thanks and sorry for such a long post! Kevin

  • How do I objectively measure an application's load on a server

    - by Joe
    All, I'm not even sure where to begin looking for resources to answer my question, and I realize that speculation about this kind of thing is highly subjective. I need help determining what class of server I should purchase to host a MS Silverlight application with a MSSQL server back-end on a Windows Server 2008 platform. It's an interactive program, so I can't simply generate a list of URLs to test against, and run it with 1000 simultaneous users. What tools are out there to help me determine what kind of load the application will put on a server at varying levels of concurrent users? Would you all suggest separating the SQL server form the web server, to better differentiate the generated load on the different parts of the stack?

  • Deploying WPF application: .NET 3.5 issues

    - by Robbert Dam
    Hi all, Users around my country are currently beta-testing our application. My app uses WPF & Linq, so I need .NET 3.5 installation. On most system, everything works find, including automatic installation on .NET 3.5 on machines that do not have that installed yet. However, on one machine (XP SP2) my application does not run. The user reported no issues during .NET 3.5 installation (except for a process that need to close before the installer could continue - he closed the process and continued). The application crashes on startup. To debug this issue, I did the following: Have him reboot his machine Let him manually re-install the .NET 3.5 framework (no errors reported) Have him run a test WPF app that only displays a button - also crashes Let him send the .NET 3.5 installation logs - these are huge, don't now where to look Does anyone have strategy on how to debug such issues? I expect that this will occur more when the application is released..

  • ASP-style tags for Perl web development?

    - by Alex R
    I feel like I'm traveling 10 years back in time by asking this, but... Are there any modules, patches, or any "new" version of Perl (released in the last 10 years) to enable writing web-oriented Perl scripts using ASP-style tags? e.g. from ASP/JSP some html <% some code %> more HTML e.g. from PHP some html <? some code ?> more HTML Please don't worry about "why" I'm asking this... It's related to programming language research.

  • how to start a smartdevice application minimized in c#

    - by x86shadow
    I made a smart device application in c# and I want to run it at startup (I know how to do that) but the problem is that I can't make my application to run minimized (hidden) on the first time. I've tried this.Hide() and this.Visible = false and also used ShowWindow API with SW_HIDE(6) but non of them worked. It seems it's impossible to use these methods on Form_Load() or in InitializeComponent() to start the application minimized or hidden. anyone can help me with this ?
