I raised a question here but realized I was going the wrong direction. I need to create a virtual monitor (really just the space in memory) that is large enough to fit a website, that would normally span several screens. Is this possible in any language? I tried Java, but failed miserably so far. I don't expect this to be easy, any pointers would appreciated. I'd imagine the OS and the video cart would have to told in somehow that there's a third monitor. Use any Virtualization tool (VirtualBox, VMWare, etc). Create a Windows (XP/newer) virtual machine, and you can attach any number (well, at

I need to get specifications of hard disk on both Win and *nix machines. I used <hdreg.h> on Linux like this: static struct hd_driveid hd; int device; if ((device = open("/dev/sda", O_RDONLY | O_NONBLOCK)) < 0) { cerr << "ERROR: Cannot open device /dev/sda \n"; exit(1); } if (!ioctl(device, HDIO_GET_IDENTITY, &hd)) { cout << hd.model << endl; cout << hd.serial_no << endl; cout << hd.heads << endl; } I need hd_driveid to tell me some more information about disk. I want to know: Number of partitions Specifications of each partition (format, label, flags, size, start point, number of tracks etc.)

For regular readers: The saga™ continues... My app runs fine on my development machine - which was purchased (5 years ago) as a fairly good gaming rig. As such, it's 64bit, has a 2.2GHz clock-speed and has 2GB of memory. The machines at work however, are standard Dell issue office computers and really struggle to even start my app, let alone run it. ( Explanation... I can imagine people screaming at me: "What on earth are you doing to require a spec like that?" Well, I'm doing a lot of real time image analysis and audio generation. So there. ) Our team has the budget to buy a dedicated laptop

This question already has answers here : INC instruction vs ADD 1: Does it matter? (2 answers) I've read many times over the years that you should do XOR ax, ax because it is faster... or when programming in C use counter++ or counter+=1 because they would INC or ADD... Or that in the Netburst Pentium 4 the INC was slower than ADD 1 so the compiler had to be warned that your target was a Netburst so it would translate all var++ to ADD 1... My question is: Why INC and ADD have different performances? Why for example INC was claimed to be slower on Netburst while faster than ADD in other

I need to check that android device's manufacturer is dell or not. But I haven't dell device, so cant get actually name of manufacture of device(for dell). I'm using android.os.Build.MANUFACTURER; Does anyone know that what is the value returned for the above query in case of a dell device? Zimbabao Here is the wikipedia link about Android devices and MANUFACTURER strings. EDIT: That Wikipedia page has been deleted. Here is a PDF list from Google Play which lists all supported devices and their manufacturers. Try this: String deviceName = android.os.Build.MODEL; 来源： https://stackoverflow.com

I've been interested in hardware programming recently, but I have not started yet. I did some searching working, and have a vague idea: Arduino is a combination of both chip and breadboard. AVR is a single chip, and need to buy a breadboard to get started. Is that statement true or false? kersny AVR is just an integrated circuit microchip, made by Atmel. It looks something like this: Although they can be used by themselves, it takes a bit of hardware experience and some support components. The Arduino is an AVR processor running special code that lets you use the Arduino environment to program

I have a number of questions about Intel PT (have been trying to decode the manual but is very difficult). My questions are: I am trying to find out if Intel PT can be disabled or reconfigured from within an OS, or, more generally, from within the system it is providing a trace of. Does Intel PT generate events on writes to specific registers - such as CR3, IDTR, etc Can Intel PT write values back to the system - i.e. can an external debugging machine actively perform writes to register, cache or memory? Any help is much appreciated, thankyou!! I'm also currently figuring out how to use Intel
