• How to populating Ontology at runtime?

  - by Chan

  Hi, I have a configuration file with a lot of data like sensor locations, type, rules for activating devices etc. Basically related to a pervasive system. I plan to design an ontology for this domain. The doubt in my mind is how should I populate the ontology with the information in the configuration file, as the configuration files are going to change every now and then. Earlier I was planning to use XML, so I can just read the configuration file at runtime and create an XML as per the XSD. Do we use the same technique for Ontologies? If yes then what is the format of the populated ontology? Thanks Chan

• How can I grab the iTunes-defined name for my iPhone/iPod device?

  - by Christophe Porteneuve

  Hey there, I'm trying to get the name for an iPhone/iPod device that the user entered in their iTunes. This is not, I repeat, not, necessarily what [[UIDevice currentDevice] name] returns (or any of its other methods). For instance, my iPhone is bound in iTunes to "iPhone 3G de Christophe…", to differentiate it from my wife's and other similar devices. That's the name I'd love to be able to grab. Is it stored anywhere on the device, and if so can I access it somehow? Thanks!

• How do you protect code from leaking outside?

  - by cubex

  Besides open-sourcing your project and legislation, are there ways to prevent, or at least minimize the damages of code leaking outside your company/group? We obviously can't block Internet access (to prevent emailing the code) because programmer's need their references. We also can't block peripheral devices (USB, Firewire, etc.) The code matters most when it has some proprietary algorithms and in-house developed knowledge (as opposed to regular routine code to draw GUIs, connect to databases, etc.), but some applications (like accounting software and CRMs) are just that: complex collections of routine code that are simple to develop in principle, but will take years to write from scratch. This is where leaked code will come in handy to competitors. As far as I see it, preventing leakage relies almost entirely on human process. What do you think? What precautions and measures are you taking? And has code leakage affected you before?

• QML 5.3 iOS compilation of pure QML app

  - by Nathaniel Johnson

  I have an application written in QML. Initially, I used the standard C++ bootstrap for the app. int main(int argc, char *argv[]) { QApplication app(argc, argv); // A bunch of components and data models written in C++ QQmlApplicationEngine engine; engine.load(QUrl(QStringLiteral("qrc:///main.qml"))); return app.exec(); } The bulk of the app is in QML and the more I work with QML, the happier I am with it and the more I feel comfortable converting the C++ pieces to QML. So, it comes to one risk that I wanted to ask about. If I convert the app to a pure QML application like the kind generated by the Qt Quick UI application wizard with no C++ and designed to be run with qmlscene will I be able to compile it for iOS when the time to port it comes or will I end up just converting it back to the C++ loader form? TL;DR Can pure QML (no C++) apps be compiled and run on iOS devices?

• SNMP from the browser

  - by moogs

  There"s this idea of having a web app search for devices in the network (with elevated user permissions, of course). Checking the silverlight and flash APIs, there does not seem to be a way to do SNMP ( the UDP APIs are limited to multicasting media ). Anyone know a clever workaround? In windows, a small XBAP utility can do the SNMP stuff, but that leaves out the Mac OS X platform. Thanks for any ideas. ( I do have a SO account but I"m in a not so trustworthy public PC right now so I didn"t log in. )

• Android multiple screen sizes and density problems

  - by Ben Mc

  I'm having a real problem with my drawables that I just can't seem to figure out. The problem is this: There are screen sizes at approximately 320x480, 480x800, 480x854 Then there are most commonly densities at 1.0 (160) and 1.5 (240) Now, on a Droid, the screen size is 480x800 and the density is reporting using DisplayMetrics as 1.5 On the G1, it's 320x480 and reporting back at a density of 1.0 BUT tablet devices are reporting back at 480x800 with a density of 1.0 (160) So, I'm going mad because I can put 320x480 images in the drawables-mdpi folder and 480x800 images in the drawables-hdpi folder, but on Tablet computers, no matter what it's not resizing up anything to a full screen. Any help would be greatly appreciated. I just want all of my 320x480 images to scale up regardless of the device.

• Questions about linux root file system.

  - by smwikipedia

  I read the manual page of the "mount" command, at it reads as below: All files accessible in a Unix system are arranged in one big tree, the file hierarchy, rooted at /. These files can be spread out over several devices. The mount command serves to attach the file system found on some device to the big file tree. My questions are: Where is this "big tree" located? Suppose I have 2 disks, if I mount them onto some point in the "big tree", does linux place some "special marks" in the mount point to indicate that these 2 "mount directories" are indeed seperate disks?

• Streaming audio - where to start?

  - by Adam Davis

  I need to develop an embedded audio streaming server. Requirements: Voice quality or better Intended for low power wifi transmission Broad support in existing software and devices (ie, windows media player, quicktime, vlc, iPhone, Android, etc). Royalty/patent free, or cheap to license Preferences: Low overhead TCP/IP based streaming protocol Voice grade codec (easy to implement in software, no DSP, 32bit CPU if needed) Would be nice if it supported HTML5 browsers, but is there any codec (such as raw) that is supported by the latest browsers that is lower overhead than MP3? Therefore: What are the relevant streaming protocols I should be looking at? What are the relevant codecs I should be looking at? What transport streams should I be looking at? What am I missing, or where else should I be looking for this type of need?

• Can UMDF drivers be packaged/shipped via WiX?

  - by Rafael Rivera

  Howdy Internets: I put together a WiX 3.0 package, utilizing the DIFx extensions, with the intentions to install a Windows 7 Sensor (UMDF driver). During installation, DIFXAPP logged "No matching devices found in INF" and simply threw the driver into storage. I read I'm to populate my INF with an appropriate DriverPackageType, but according to MSDN's enumerated list, nothing fits. Is UMDF driver installation a supported scenario? If not, what's the best practice for using WiX to install such drivers? Disassembling the DIfx extension shows intent to support Co-installer packages, I have yet to try 3.5 beta.

• About sqlite use.

  - by rantravee

  Hi, There are some things my application needs to do on first start up(first startup after update) . These actions could be described in a .txt file and then when it is the case read the file and do according to it ,or on the other hand (I lean to use this option) a sqlite database could be used to store the information . The apk file would be shipped with an .txt file/prebuild sql db stored in res/raw or res.asset and then copied into proper space and used. This I have figured out how !, though I'm not sure which option of this two would be the fittest ? One thing that is unclear to me is how could sqlite version mismatch affect me, and if it serious enough to take into consideration ? I 'm using Android api level 4 (Android 1.6) and the future application might be used on several different devices , with different api levels.

• Pocket IE onmousedown onmousemove onmouseup ?

  - by eidylon

  Hello all, I have a control which I wrote for capturing signatures on a web page, by using onmousedown, onmousemove and onmouseup on a div to track the mouse, and capture points comprising a signature. Now we need this to work on Windows Mobile 6.5 powered devices... but it seems that the div element does not support the mouse events in Pocket IE, which would seem to be supported by this blog. But according to MSDN, the WinCE (which WinMo/PPC is based off of) version of IE does support these mouse events for some unknown list of elements. So can anyone tell me, are there any elements: img, a, span or whatever that support onmouse[down|move|up] in WinMo 6.5 Pocket IE? Thanks! If not, anyone have any other ideas for capturing a signature on a web page in Pocket IE?

• In writing games that deal with scancodes, what do I need to know to support international keyboards

  - by sludge

  I am writing an input system for a game that needs to be able to handle keyboard schemes that are not just qwerty. In designing the system, I must take into consideration: Two types of input: standard shooter controls (lots of buttons being pressed and raw samples collected) and flight sim controls (the button's label is what the user presses to toggle something) Alternative software keyboard layouts (dvorak, azerty, etc) as supplied by the OS Alternative hardware keyboard layouts that supply Unicode characters My initial inclination is to sample the USB HID unicode scancodes. Interested on thoughts on what I need to do to be compatible with the world's input devices and recommendation of input APIs on both platforms.

• how to target css to iPad but exclude Safari 4 desktop using a media query?

  - by miriam835work

  I am trying to use a media rule to target css to iPad only. I want to exclude iPhone/iPod and desktop browsers. I would like to to also exclude other mobile devices if possible. I have used <style type="text/css" media="only screen and (min-device-width: 768px) and (max-device-width: 1024px)"> but just found out that desktop Safari 4 reads it. I have tried variations with "481px" instead of "768px" and another that adds an orientation to that: <style type="text/css" media="only screen and (min-device-width: 481px) and (max-device-width: 1024px) and (orientation:portrait)"> but not luck. (Later we will be sniffing user-agent strings for iPad, but for now that solution won't work.) Thanks!

• How to know preferred icon size for MenuItem?

  - by barmaley

  Hi folks, I my application I have one large PNG file containg hi-res image. Depending on situation I would like to use this image either as icon or as placeholder for ImageView. For MenuItem this image is too large, so I need to scale-down it to suitable size. I mean if it has to be displayed on large enough device like Samsung Galaxy Tab - I need to use one scale, for in small ones another, etc. I just noticed that for small-sized devices MenuItem icon is not scaled just cut - which is ugly. So the question is how should detect which is preferred size?

• How to pass data to another droid device when the other device isn't expecting it

  - by James Black

  I am working on an application and one feature that would make it really useful is the ability to share some information, but the other device may not be expecting the data to be sent. For example, if I am reading a really good book, and I realize that a friend may like it, I could use an application to send the data to him, so he could order the book from Amazon. But, since he isn't expecting the data, I would hate for the application to be polling a server every so often, as that will be needlessly draining the battery. Ideally it would be great if there was a way to make a phone call to the target device, send a data packet and end the call. If it could be done and prevent the phone from ringing, then it would be very useful to me. I am curious if there is some way to send data between devices without polling.

• Creating my own SAP dashboard/reporting tool for mobile

  - by novwareman

  Hi! Is it possible to create my own mobile dashboard, reporting tool for SAP? I understand the standard components to be used for this purpose are: Business Objects Enterprise Server XI - this provides reporting functionalities for SAP Business Objects Mobile Server - this connects to Enterprise Server and optimizes reports stored there for mobile devices Mobile Web Browser or Mobile Business Objects Report Client - for viewing the reports I don't intend to purchase the components mentioned above. I only want to know if it's feasible to build my own solution. I am familiar with BAPI's to retrieve data from SAP. What is the proper approach to build an SAP reporting tool? Thank you!

• Improve responsiveness of $(...).click on touch interface

  - by Bram W.

  I need access to a web-based on screen keyboard which will be used on a touch interface. This example looks nice and functional, however when I try it on an iPad, the responsiveness it very low IMHO. It's not comfortable to use and sometimes whole words are misspelled due to slow response. Is there a way to improve the experience on this type of on screen keyboard? This implementation uses the $('#id').click(...); function to process the events. Is there a better way to achieve the goal of typing on the screen? Are there better plugins out there? Note: The final application will run on different types of devices. For several reasons, native on screen keyboards are no option.

• Suggest books/learning path for writing smartphone apps

  - by chibineku

  I have been writing a lot of HTML, CSS, PHP, MySQL and JavaScript lately working on a website, and I would like to move on to 'proper' OOP with an eye to making smartphone apps. I would like to at least cover iPhone and BlackBerry, which means learning Objective C, Cocoa and Java, before learning the specifics of interacting with the devices themselves, such as native bluetooth/GPS/internet API/methods. I would appreciate pointers to books or resources that will get me from a procedural web developer to object oriented app-maker. Most of the reviews of books on Objective C and Java have been mixed. I am about to start working my way through Beginning Java Objects (APress) which I have borrowed from my brother, so even if it's not a good intro at least it was free!

• GKSession sendDataToAllPeers including sender?

  - by Typeoneerror

  I've got a number of devices connected over wifi using GameKit. I have a simple UIAlertView popping up when peers receive data. All but the sendee show this alert view when data is sent, so I'm wondering if that's a bug in my app or if that's expected behavior. If the device doing the sending is also a GKSessionModePeer, I would expect it to "fire" its receiveData: message as well since I'm sending to all peers. Should I call a method manually at the same on the sendee device? For example, if I wanted to send a "GameStart" packet to the 4 phones, the peers would call startGame: in the receiveData:fromPeer:inSession:context: method when it receives that packet and the sendee would be calling sendDataToAllPeers: and call startGame: on itself. Does that sound right or is there a way to include the sendee in the sendDataToAllPeers: list so that it responds exactly the same as all connected peers?

• Problems wih minSdkVersion 1.5

  - by Tebam

  Hello, we have a problem related to the manifest file and the property "android:minSdkVersion". The issue is: If our platform is 2.0 and we use the property "android:minSdkVersion=3" (3 = sdk 1.5) the graphics get corrupted (In details, the application's resolution get reduced to a 2/3 part of the original size, this is, when the resolution should be 480x720, it becomes in a 320x480). This is happening on the Android emulator, and on the devices Droid/Milestone (Which are platforms 2.0). When we switch the property to "android:minSdkVersion=4" (4 = sdk 1.6) the problem gets solved, but when we want to put that version on platform 1.5, Android doesn't allow us to install it. It would help us to know any conflict regarding graphics within the 2.0 sdk, or any known problem around the "android:minSdkVersion" in the manifest. Thanks!

• Can I update an iOS Enterprise App in the background like an App Store app can?

  - by lehn0058

  I have an iOS enterprise app that we are wirelessly distributing to our devices. Currently the app polls our server once a day to see if there is an app update. If there is, we try to install it by having the app call the following code: NSURL *installUrl = [NSURL URLWithString:[NSString stringWithFormat:@"itms-services://?action=download-manifest&url=%@", plistUrl]]; [[UIApplication sharedApplication] openURL:installUrl]; This causes the app to prompt the user with an alert dialog to install the update. If they click install, the app closes and the update is downloaded and installed. I am wondering if there is anything for enterprise apps for iOS 7 similar to the AppStore's automatic updates? I would like to be able to update our app without the user having to press an update button and be able to update at a time when the user won't have to wait for it to install.

• Why does the release build of my iPhone app crash on the device on the first run after installation?

  - by Chris Cooper

  I have an iPhone app that's been in development for about 2 weeks. We recently tried the "release" version of the build on a device, and to our great unhappiness, it crashes in one of the views with an "EXC_BAD_ACCESS". This crash only occurs on devices, and only in the "release" build. Not only that, but it only happens the first time the app is launched! It is also 100% reproducible. We have removed the small block of code that deals with data persistence, and have tried re-openning Xcode, cleaning the project, deleting and reinstalling the app, etc., as some other questions suggest. Do you have any advice for a) what might be causing this problem, and b) how to go about debugging if it only happens in "release"? Thanks

• Best way to handle input from a keyboard "wedge"

  - by Mykroft

  I'm writing a C# POS (point of sale) system that takes input from a keyboard wedge magcard reader. This means that any data it reads off of a mag stripe is entered as if it were typed on the keyboard very quickly. Currently I'm handling this by attaching to the KeyPress event and looking for a series of very fast key presses that contain the card swipe sentinel characters. Is there a better way to deal with this sort of input? Edit: The device does simply present the data as keystrokes and doesn't interface through some other driver. Also We use a wide range of these types of devices so ideally a method should work independent of the specific model of wedge being used. However if there is no other option I'll have to make do.

• Anyone knows of a good addressbook implementation?

  - by Tsahi Levent-Levi

  I am looking to add an address book to one of my programs. For that purpose, I want to have something that is flexible and customizable to the point of allowing me to hook up additional metadata to contacts in it from third parties. I don't mind paying for a solution as long as I get something that is usable for me. My requirements: Optimized to run on embedded devices Preferably in source code form Ability to add my own fields to contacts over those the address book provides out of the box Ability to plugin "stuff" to it to enhance it without changing its base code too much Has a C or C++ interface
