  • Is DiskDrive Signature unique?

    - by Ananth
    I am currently using WMI to query various details about the underlying hardware in order to uniquely identify a machine. To this end, I came across a field called "Signature" under "Win32_DiskDrive". Is this signature unique across machines (globally)? Can this be used reliably to identify the machine? Thanks, Ananth

  • What development technologies or technology stack is typically used in the security industry?

    - by vfilby
    In this case security means building security (access control, alarm systems, etc). And I am not talking about working directly with the hardware, more focused on web based applications/api's that clients or companies can use? Are there technologies that are commonly used? Are there technologies that shouldn't be used? Are there any real benefits to a linux based stack as opposed to a windows based stack for exposing web based applications?

  • How to open DataSet in Visual Studio 2008 faster?

    - by Ekkapop
    When I open DataSet in Visual Studio 2008 to design or modify it, it always take a very long time (more than five minutes) before I can continue to do my job. While I'm waiting I can't do anything on Visual Studio, moreover CPU and memory usage is growth dramatically. I want to know, Is it has anyway to reduce this waiting time? Hardware - Desktop CPU: Intel Q6600 Memory: 4 GB HDD: 320 GB 7200 rpm OS: Windows XP 32 bit with Service Pack 3

  • Mac OS on a Windows PC

    - by HDawg
    I've done a little bit of reading on the topic, but nothing too clear has turned up. Why is it so difficult to run Mac OS on a virtual machine on a PC? Some sources say it's because of hardware architecture. Is there a clear, definitive reason?

  • Performance of CSS Transitions vs. JS animation packages

    - by desau
    I'm wondering - is there any difference in performance of using CSS Transitions vs. any of the various JS animation libraries? (scriptaculous, scripty2, jsAnim, MooTools, $fx, etc, etc). I've tried various tests in Safari / Google Chrome, and I don't actually see any difference -- I thought that CSS Transitions were supposed to be hardware accelerated.

  • How would you handle making an array or list that would have more entries than the standard implemen

    - by faceless1_14
    I am trying to create an array or list that could handle in theory, given adequate hardware and such, as many as 100^100 BigInteger entries. The problem with using an array or standard list is that they can only hold Integer.MAX_VALUE number of entries. How would you work around this limitations? A whole new class/interface? A wrapper for list? another data type entirely?

  • Programmatically measure size and way-order of L1 and L2 caches

    - by osgx
    How can I measure programmatically (not query the OS, but measure) the size and order of associativity of L1 and L2 caches (data caches)? Assumptions about system: It has L1 and L2 cache (may be L3 too, may be cache sharing), It may have a hardware prefetch unit (just like P4+), It has a stable clocksource (tickcounter or good HPET for gettimeofday). There are no assumptions about OS (it can be Linux, Windows, or something non-standard), and we can't use POSIX queries. Language is C. And compiler optimizations may be disabled.

  • Multiple apks, single listing of app for Google TV and Android Phone/Tablet

    - by Yash
    I have an Android phone/tablet apk which is currently in Play store and has these settings in its manifest file: package="com.company.xyz" android:versionCode="0803010008" android:versionName="01.00.08" > <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="8" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" /> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-library android:name="com.adobe.flashplayer" android:required="true" /> <supports-screens android:anyDensity="true" android:largeScreens="true" android:normalScreens="true" android:smallScreens="false" android:xlargeScreens="true" /> <uses-feature android:name="android.hardware.touchscreen" android:required="true" /> I had uploaded another apk for GoogleTV which has the same package name com.company.xyz as the previous apk and has the following settings in its manifest file: package="com.company.xyz" android:versionCode="1203010001" android:versionName="01.00.01" > <uses-sdk android:minSdkVersion="12" android:targetSdkVersion="12" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-feature android:name="android.hardware.touchscreen" android:required="false" /> <uses-feature android:name="com.google.android.tv" android:required="true" /> <supports-screens android:largeScreens="true"/> <uses-configuration android:reqFiveWayNav="true" /> The Google TV apk never showed up on Play Store on GTV boxes, so I updated its manifest with the settings below and with everything else remaining the same package="com.company.xyz" android:versionCode="1203010002" android:versionName="01.00.02" > <supports-screens android:largeScreens="true" android:normalScreens="false" android:smallScreens="false" android:xlargeScreens="false" /> At this point, I am unable to save the app because of the Play Store error "Error: New APK version is lower than previous APK version" even though the GoogleTV apk has a higher version code than the Phone/Tablet version. Does anyone have a solution for this? Thanks!

  • How can I access UDP ports using a web application on the client PC?

    - by Vaibhav
    One of the thing that current Windows application does is that it writes out information to a hardware device via a UDP message. We are considering porting the application to web-based. I checked Silverlight, and that doesn't allow UDP. We don't want to use ActiveX or Java Applets. What are the other options? Thanks. Update - does anyone know if I can use Flash to do this?

  • Does the VB6 IDE run on Windows 7 64-bit

    - by jasonk
    We're approaching a point of replacing several of our developer PCs and would like to move up to 64-Bit to maximize the hardware/life of the PCs but we also need to support several legacy VB6 applications. That said, does the VB6 IDE run on Windows 7 64-bit? Microsoft says it's not supported, but that doesn't necessarily mean it doesn't work. Does it work? Are there any pitfalls/workarounds needed to get it running?

  • OpenGL Video RAM Limits

    - by Tamir
    I have been trying to make a Cross-platform 2D Online Game, and my maps are made of tiles. My tileset, which I render the tiles from, is quite huge. I wanted to know how can I disable hardware rendering, or at least making it more capable. Hence, I wanted to know what are the basic limits of the video ram, as far as I know, Direct3D has a texture size limits (by that I don't mean the power-of-two texture sizes).
