• RockBand-like voice app for PC/OSX / Real time pitch display software

  - by Sai Emrys

  I played Rock Band 2 for the first time a little while ago (at Notacon). One thing I enjoyed about it was getting real-time feedback about my singing. I think it'd be neat to have something like that to run alongside my usual music, so that I can sing to random stuff in my music collection and know when I'm hitting the notes. Is there something like this for PC - ideally for OSX, and ideally that can just operate on arbitrary songs? I don't really care if it's game-like (though that's neat too); I just want it for the singing feedback. And I have no need for pitch correction - ideally what I'd see is just the pitches of the notes in the music and (on the same scale, differently displayed) of the live microphone. I tried to STFW but got no salient hits. :-/ Thanks!

• SATA hard disk for laptop on Desktop PC

  - by Lawliet

  I know that this forum is for programming-related questions only, but I'm having this dilemma so here I go. Can I connect a laptop SATA hard disk to Desktop PC? Do I have to use some adapters or I can just plug in SATA power connector and SATA data cable like my Desktop hard disk is connected? I noticed that both laptop and desktop SATA disks use same connectors, but I'm afraid that I might fry my laptop hard disk because the SATA connector has both 12V and 5V voltage (given the fact that laptop hard disks has input voltage of 5V) Thanks in advance

• Control Philips Living Colors using PC

  - by CrazyChris

  Hi guys, is there a way (hardware/software-combination) that I can use to control one or more "Philips Living Colors" lamps using a PC - e.g. a USB-stick that acts as the "remote". This way i could control the lamp through software (e.g. a web-app - over iPhone / remotely) or even create what Philips builds into some of their TVs and calls "ambilight" (graphics driver detecting the main color to control the lamp). I guess this is more like a hardware than a software question - but I couldn't find anything about this online and I'm sure not to be the first to have come up with this idea right when I unpacked my LivingColors lamp yesterday ;) Any idea/hint is appreciated. -chris

• Turn off the display on remote PC

  - by concretemixer

  Hello. I'm fixing some bugs in the application for remote control (remote desktop-like) for Windows. And there is a feature that you can blank screen on remote machine - all the programms keep running unaffected, but the person who looks into the display on remote PC sees nothing but black screen. It is implemented by sending IoCtl request IOCTL_VIDEO_SET_OUTPUT_DEVICE_POWER_STATE, which is undocumented. And this request does not work on Vista and above. Are there another ways to do what I want? In fact, SendMessage(-1,WM_SOMMAND,SC_MONITORPOWER,2) does the trick, but screen turns back on if someone toches keyboard/mouse.

• Documentation for Qt documentation comments? Qt + Doxygen?

  - by Jake Petroules

  Where can I find documentation for Qt documentation comments? I'm referring to how Qt uses a specific style for documentation comments, like so: /*! \class MyClassName \brief The MyClassName class is used as an example on Stack Overflow. This class serves a few functions, the most important being: \list \i So people can understand my question. \i So people can have a few laughs at the comedy in my example. \endlist */ ...you get the picture. So where can I find information about all the switches, like \class, \list, \brief, etc. Also, what tool(s) do I use to generate documentation files from these comments in my source files? Does Doxygen support this syntax?

• PCI function number for SATA AHCI controller

  - by Look Alterno

  I'm debugging a second stage boot loader for a PC with SATA AHCI controller. I'm able to enumerate the PCI bus and find the hard disk. So far, so good. Now, lspci in my notebook (Dell Inspiron 1525) show me: -[0000:00]-+-1f.0 Intel Corporation 82801HEM (ICH8M) LPC Interface Controller +-1f.1 Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) IDE Controller +-1f.2 Intel Corporation 82801HBM/HEM (ICH8M/ICH8M-E) SATA AHCI Controller \-1f.3 Intel Corporation 82801H (ICH8 Family) SMBus Controller My question: Is SATA AHCI Controller always function 2 in any PC? If not, how I found? I don't pretend to be general; booting my notebook will be good enough, without compromise further refinements.

• Med-PC Programing Language

  - by mknuii

  There's this programing language called Med-PC that works with animal behavior. I'm trying to learn a bit about it, but i can't seem to find any kind of books or material about it. I've "google it" but all i seem to find are some references about it and a PDF explaining the installing of the program itself and sensors(for the experiments), not actual programing instructions. I'm looking for some kind of guidance, documents or books, some kind of reference where i can improve and learn about this language, or if it is based on some other language. I just need some reference about it. So i've resorted to StackOverFlow to see if anybody has worked, knows about it or can point me some links/books about it.
