  • Windows 7 Hibernate Problem

    - by goygoycu
    I cannot hibernate windows. When I click "hibernate", my laptop(windows) just locks and the screen goes black. I can unlock without any problem. I do not have any problem with other options such as "sleep" or "shut down". I updated the chipset drivers but it did not help. There is not any option in BIOS about the sleep modes. "Hibernate" is "on" on Windows. Any advice? My Laptop specifications: MSI A5000 3gb system memory, Windows 7 Home Premium 32bit installed, Gentoo linux installed, Grub bootloader(MBR). Hard drive: Around 4gb of free space in windows partition.

  • Require password to login to Nexus 7

    - by gnudoc
    The default behavior in the Nexus 7 Image is to log straight in to the default user's desktop, bypassing the lightdm greeter. This seems like an acceptable behavior for testing the core but it's clearly insecure. I've changed the default password and would like lightdm to actually require the password to be entered, rather than just having a button that says "login". I've turned automatic login on and off in System Settings ? User Accounts but this doesn't help. Any suggestions?

  • Down to the Wire - Yet More Solaris Things to See at OpenWorld (and JavaOne!)

    - by Larry Wake
    San Francisco is bracing for the annual invasion. The airport's jammed, the tweets are flying, and the numbers are crazy: more than 50,000 attendees and 2,500+ sessions, taking over Moscone Convention Center, two streets, Union Square, and seemingly every hotel in town (98,000 hotel room nights). So yeah, it's busy. And it's not just OpenWorld--we've also got JavaOne, MySQL Connect, and four other sub-events going on as well. Speaking of JavaOne, you can find Solaris-related activity there, too -- I've highlighted one hands-on lab below. Here's a last pre-event roundup of activities for consideration; enjoy the show(s)! (Remember, Schedule Builder is your friend; use it with the session numbers below to register.) Monday, October 1st: 3:15 PM - General Session: Accelerate Your Business with the Oracle Hardware Advantage(GEN9691, Moscone North Hall D) John Fowler, head of Oracle's Systems organization, will talk about Oracle hardware technology and how it's co-engineered with other key technologies, including Oracle Solaris. Tuesday, October 2nd: 10:15 AM - Building an IaaS Platform with SPARC, Oracle Solaris 11, and Oracle VM Server for SPARC(CON4431, Moscone South 270)Get the birds-eye lowdown (whatever that means) on how U.S. Cellular  built its Infrastructure as a Service (IaaS) cloud delivery platform with Oracle’s SPARC T4 servers, Oracle Solaris 11, Oracle Solaris Cluster 4, and Oracle VM Server for SPARC. The session covers the high-level design, business case made, implementation details, and lessons learned. 11:45 AM - Oracle Solaris 11 Panel: Insights and Directions from Oracle Solaris Core Engineering(CON8790, Moscone South 252) This has been one of the livelier Solaris-related sessions in years past (and I'm not saying that just because I get to moderate it this year). A panel of core engineers responsible for a wide range of key Solaris technologies will talk about some of the interesting work they've been doing -- but mostly we keep time open for the panel to take questions from attendees, because that's the fun part. Wednesday, October 3rd: 10:00 AM - Tracing Your Java Application Tuning on Oracle Solaris with DTrace(HOL10214, Hilton San Francisco, Franciscan A/B/C/D) This JavaOne hands-on lab will show how to use the DTrace framework to dynamically trace your Java applications on Oracle Solaris and uncover new tuning opportunities. Thursday, October 4th: 12:45 PM - Oracle Solaris 11: Optimized for Oracle Database, Oracle WebLogic Server, and Java(CON8800, Moscone South 252) Explore how Oracle Solaris 11 has been built to be the best platform for the cloud and enterprise applications, with built-in optimizations to improve performance and deliver unique functionality with Oracle Database, Oracle WebLogic Server, and Java.

  • My company's management wants to deduct from the salary of under performing employees. How can I convince them not to?

    - by Sparky
    My company's management wants to deduct from the salary of under performing employees. I'm a member of the Core Strategy committee and they want my opinion also. I believe that the throughput from an employee depends on a lot of things such as the particular work assigned to them, other members of his/her team, other reasons etc. Such penalizations will be demoralizing to the people. How can I convince my management not to do so?

  • How should VertexBuffers be used with Multiple Monitors in DirectX 9

    - by Joshua C
    I am currently using DirectX 9 on a machine with two GPUs and three monitors. I am currently trying to draw a triangle on each monitor using vertexbuffers; A directx helloworld with multiple monitors if you will. I am familiar with some DirectX coding, but new to multiple monitor DirectX coding. I may be going about this the wrong way, so please do correct me if I'm doing something wrong. I have created a Direct3D Device for each enumerated adapter sharing the same Form handle. This allows me to successfully use all three monitors in full-screen mode. For Each Adapter In Direct3D.Adapters Dim PresentParameters As New PresentParameters 'Setup PresentParameters PresentParameters.Windowed = False PresentParameters.DeviceWindowHandle = MainForm.Handle Dim Device as New Device(Direct3D, Adapter.Adapter, DeviceType.Hardware, PresentParameters.DeviceWindowHandle, CreateFlags.HardwareVertexProcessing, PresentParameters) Device.SetRenderState(RenderState.Lighting, False) Devices.Add(Device) Next I can also draw text to each device successfully using a different Font for each Device. When I render a triangle using a different VertexBuffer for each Device, only two monitors display the triangle. One of the two monitors on the same GPU, and the monitor on it's own GPU display properly. VertexBuffer = New VertexBuffer(Device, 4 * Marshal.SizeOf(GetType(ColoredVertex)), Usage.WriteOnly, VertexFormat.None, Pool.Managed) Dim Verts = VertexBuffer.Lock(0, 0, LockFlags.None) Verts.WriteRange({ New ColoredVertex(-.5, -.5, 1, ForeColor), New ColoredVertex(0, .5, 1, ForeColor), New ColoredVertex(.5, -.5, 1, ForeColor) }) VertexBuffer.Unlock() VertexDeclaration = New VertexDeclaration(Device, { New VertexElement(0, 0, DeclarationType.Float3, DeclarationMethod.Default, DeclarationUsage.Position, 0), New VertexElement(0, 12, DeclarationType.Color, DeclarationMethod.Default, DeclarationUsage.Color, 0), VertexElement.VertexDeclarationEnd }) Render Code: Device.SetStreamSource(0, VertexBuffer, 0, Marshal.SizeOf(GetType(ColoredVertex))) Device.VertexDeclaration = VertexDeclaration Device.DrawPrimitives(PrimitiveType.TriangleList, 0, 1) I have to assume the fact that they share the same physical card comes into play. Should I use multiple buffers on the same card, and if so, how? Or what is the way I should access the VertexBuffer across Devices? Another thought I had was the non working monitor acts like there are no lights. Is turning off lighting on each device on the same card causing issues somehow?

  • IE attachEvent on object tag causes memory corruption

    - by larswa
    I've an ActiveX Control within an embedded IE8 HTML page that has the following event MessageReceived([in] BSTR srcWindowId, [in] BSTR json). On Windows the event is registered with OCX.attachEvent("MessageReceived", onMessageReceivedFunc). Following code fires the event in the HTML page. HRESULT Fire_MessageReceived(BSTR id, BSTR json) { CComVariant varResult; T* pT = static_cast<T*>(this); int nConnectionIndex; CComVariant* pvars = new CComVariant[2]; int nConnections = m_vec.GetSize(); for (nConnectionIndex = 0; nConnectionIndex < nConnections; nConnectionIndex++) { pT->Lock(); CComPtr<IUnknown> sp = m_vec.GetAt(nConnectionIndex); pT->Unlock(); IDispatch* pDispatch = reinterpret_cast<IDispatch*>(sp.p); if (pDispatch != NULL) { VariantClear(&varResult); pvars[1] = id; pvars[0] = json; DISPPARAMS disp = { pvars, NULL, 2, 0 }; pDispatch->Invoke(0x1, IID_NULL, LOCALE_USER_DEFAULT, DISPATCH_METHOD, &disp, &varResult, NULL, NULL); } } delete[] pvars; // -> Memory Corruption here! return varResult.scode; } After I enabled gflags.exe with application verifier, the following strange behaviour occur: After Invoke() that is executing the JavaScript callback, the BSTR from pvars[1] is copied to pvars[0] for some unknown reason!? The delete[] of pvars causes a double free of the same string then which ends in a heap corruption. Does anybody has an idea whats going on here? Is this a IE bug or is there a trick within the OCX Implementation that I'm missing? If I use the tag like: <script for="OCX" event="MessageReceived(id, json)" language="JavaScript" type="text/javascript"> window.onMessageReceivedFunc(windowId, json); </script> ... the strange copy operation does not occur. The following code also seem to be ok due to the fact that the caller of Fire_MessageReceived() is responsible for freeing the BSTRs. HRESULT Fire_MessageReceived(BSTR srcWindowId, BSTR json) { CComVariant varResult; T* pT = static_cast<T*>(this); int nConnectionIndex; VARIANT pvars[2]; int nConnections = m_vec.GetSize(); for (nConnectionIndex = 0; nConnectionIndex < nConnections; nConnectionIndex++) { pT->Lock(); CComPtr<IUnknown> sp = m_vec.GetAt(nConnectionIndex); pT->Unlock(); IDispatch* pDispatch = reinterpret_cast<IDispatch*>(sp.p); if (pDispatch != NULL) { VariantClear(&varResult); pvars[1].vt = VT_BSTR; pvars[1].bstrVal = srcWindowId; pvars[0].vt = VT_BSTR; pvars[0].bstrVal = json; DISPPARAMS disp = { pvars, NULL, 2, 0 }; pDispatch->Invoke(0x1, IID_NULL, LOCALE_USER_DEFAULT, DISPATCH_METHOD, &disp, &varResult, NULL, NULL); } } delete[] pvars; return varResult.scode; } Thanks!

  • [C++] Producer/Consumer Implementation -- Feedback Wanted

    I'm preparing for an interview in a few weeks and I thougth I would give threads in boost a go, as well as do the simple producer/consumer problem I learned in school.
