  • How to use windows desktop from a linux machine in a local network?

    - by Hristo Hristov
    I have a computer running Windows 7 with no monitor or keyboard, connected to a local network. I have a few laptops running linux, also connected to the local network. I want to feel like I'm sitting in front of the windows, but using one of the linux laptops. How to do that? Maybe I can use some linux software to connect to remote desktop? Or I have to install client/server software on both machines? As this is a local network, I expect excellent experience with no lag. Thank you!

  • What is the best way to create related types at runtime?

    - by SniperSmiley
    How do I determine the type of a class that is related to another class at runtime? I have figured out a solution, the only problem is that I ended up having to use a define that has to be used in all of the derived classes. Is there a simpler way to do this that doesn't need the define or a copy paste? Things to note: both the class and the related class will always have their respective base class, the different classes can share a related class, and as in the example I would like the control class to own the view. #include <iostream> #include <string> class model; class view { public: view( model *m ) {} virtual std::string display() { return "view"; } }; #define RELATED_CLASS(RELATED)\ typedef RELATED relatedType;\ virtual relatedType*createRelated(){\ return new relatedType(this);} class model { public: RELATED_CLASS(view) model() {} }; class otherView : public view { public: otherView( model *m ) : view(m) {} std::string display() { return "otherView"; } }; class otherModel : public model { public: RELATED_CLASS(otherView) otherModel() {} }; class control { public: control( model *m ) : m_(m), v_( m->createRelated() ) {} ~control() { delete v_; } std::string display() { return v_->display(); } model *m_; view *v_; }; int main( void ) { model m; otherModel om; model *pm = &om; control c1( &m ); control c2( &om ); control c3( pm ); std::cout << c1.display() << std::endl; std::cout << c2.display() << std::endl; std::cout << c3.display() << std::endl; }

  • Wacom tablet or Evoluvent Vertical Mouse

    - by Bob Smith
    Having tried a number of mice that didn't help with wrist pain, I am contemplating buying a Wacom tablet or Evoluvent Vertical Mouse. I have heard great things about both of them. What do you recommend for someone with wrist pain in both hands that seems to be getting worse by the day? PS: I work mostly in Windows and Visual Studio environment. I currently have the MS natural ergonomic keyboard. I have started taking regular breaks and am also planning to see a doctor.

  • Does ILOM on recent Sun rackmount servers fully support Linux?

    - by orange80
    Do the recent Sun rackmount servers with ILOM fully support installation of Linux (Ubuntu or Fedora maybe) via the ILOM (connected by ssh) without having to hook up a display, kbd, and mouse? I have an old Sun v20z right now that will install Solaris no problem over the Service Processor but when trying to install Ubuntu 9 64-bit server I get one line on the console then it goes blank. I'd be interested in know which if any of the recent x64 models would allow me to install and run linux while completely avoiding any need for external display, keyboard, or mouse. Thanks!

  • I get regular power surges and my UPS ticks a lot due to a welding plant. Is this good or bad?

    - by EApubs
    In our home, there is a mechanic who often use a welding plant. When he use it, I think we get a power surge. My UPS ticks madly (not beep, it ticks). Sometimes, I even lose power to the keyboard. When typing, some keys get missing. 1) My question is, is it good for the computer? The UPS claimed to have surge protection. But isn't it working? What should I do to protect my PC? 2) The second question is, I also have a broadband router which is not connected to the UPS. Will it be effected?

  • How to detect which Space the user is on in Mac OS X Leopard?

    - by georgebrock
    Mac OS X Leopard has a virtual desktop implementation called Spaces. I want to programatically detect which space the user is currently on. Cocoa is preferable but AppleScript is acceptable if there's no other way. I've seen a couple of AppleScript implementations, but the techniques they used seemed a bit too hacky to use in production code (one relied on causing and error and then parsing the error message to get the current space, the other interrogated the Spaces menu GUI)

  • How can I combine code from an old revision when I didn't branch in TortoiseMerge?

    - by gr33d
    I need to combine (merge?) some parts of an old revision with a newer revision of a file. I'm still pretty new to subversion, so I'm not sure what I'll bomb in the process. I did not branch--these are simply different revisions of a file. How do I send the sections of code from r1 to r3 where they are needed. The keyboard shortcuts and menu options for "theirs", "mine", "left block", "right block", etc aren't very intuitive. If I need 5 blocks from r1 to be after the first 10 blocks of r3, how do I do it? Shouldn't I be able to go through r1 block by block and decide if and where it belongs in r3? Thanks in advance!

Hope you can understand my problem

  • Is there a terminal that features sliding like guake and screen spliting like terminator on Linux?

    - by e-satis
    Sliding means I got the terminal always in background and I can call it with a shortcut, and it will slide down from the top of the screen like in Quake (which why the most known terminal implementing it is called guake). Splitting terminal means I can seen in one terminal tab several shells, like with screen or tmux. But I can also take the focus on each part of the terminal by clicking on it, not just with a 4 keys keyboard shortcut. Which terminator let me do. Is there a terminal that features both on Linux ? Even something I can pay for.

  • I have nice headphones. Need a wireless USB microphone so I don't have to switch to a headset to make a call

    - by mattalexx
    Right now, I have a pair of Sennheiser HD595 headphones. They are plugged into a DAC/headphone amp. I spend all day listening to music through them and they sound awesome. Then, for making calls, I have a wireless USB headset from Logitech. Problem is, I can't make calls when I'm wearing my Sennheisers but I wouldn't want to listen to music all day using the Logitech headset. So I spend my day switching in between. So the question is, how can I make calls while wearing the headphones of my choice? One thing I thought of is a wireless USB microphone that I can clip to the Sennheisers. So I'd wear the Sennheisers with this mic all day and ditch the Logitech headset. But it doesn't look like anyone makes a microphone like this. By the way, I would love if the solution didn't transmit the sound of my clacky keyboard or noisy wood flooring.

  • std::ostream interface to an OLE IStream

    - by PaulH
    I have a Visual Studio 2008 C++ application using IStreams. I would like to use the IStream connection in a std::ostream. Something like this: IStream* stream = /*create valid IStream instance...*/; IStreamBuf< WIN32_FIND_DATA > sb( stream ); std::ostream os( &sb ); WIN32_FIND_DATA d = { 0 }; // send the structure along the IStream os << d; To accomplish this, I've implemented the following code: template< class _CharT, class _Traits > inline std::basic_ostream< _CharT, _Traits >& operator<<( std::basic_ostream< _CharT, _Traits >& os, const WIN32_FIND_DATA& i ) { const _CharT* c = reinterpret_cast< const _CharT* >( &i ); const _CharT* const end = c + sizeof( WIN32_FIND_DATA ) / sizeof( _CharT ); for( c; c < end; ++c ) os << *c; return os; } template< typename T > class IStreamBuf : public std::streambuf { public: IStreamBuf( IStream* stream ) : stream_( stream ) { setp( reinterpret_cast< char* >( &buffer_ ), reinterpret_cast< char* >( &buffer_ ) + sizeof( buffer_ ) ); }; virtual ~IStreamBuf() { sync(); }; protected: traits_type::int_type FlushBuffer() { int bytes = std::min< int >( pptr() - pbase(), sizeof( buffer_ ) ); DWORD written = 0; HRESULT hr = stream_->Write( &buffer_, bytes, &written ); if( FAILED( hr ) ) { return traits_type::eof(); } pbump( -bytes ); return bytes; }; virtual int sync() { if( FlushBuffer() == traits_type::eof() ) return -1; return 0; }; traits_type::int_type overflow( traits_type::int_type ch ) { if( FlushBuffer() == traits_type::eof() ) return traits_type::eof(); if( ch != traits_type::eof() ) { *pptr() = ch; pbump( 1 ); } return ch; }; private: /// data queued up to be sent T buffer_; /// output stream IStream* stream_; }; // class IStreamBuf Yes, the code compiles and seems to work, but I've not had the pleasure of implementing a std::streambuf before. So, I'd just like to know if it's correct and complete. Thanks, PaulH

  • customized xkb layouts not working (in KDE?) after upgrade from Ubuntu 9.10 to 10.04

    - by Alan
    I customised my keyboard layout in 9.10 by editing the appropriate /usr/share/X11/xkb/symbols/ file. After upgrading to 10.04 I noticed it had overwritten all my modifications, so I recovered the layout and overwrote the symbol file's base entry. Sadly KDE (and, presumably, the entire OS) seems to ignore the files altogether. The help files don't mention anything about modifying layouts anyway (and the layout switcher seems to be using setxkbmap, which uses the above path according to its man page), so I'm at a bit of a loss. Do I need to compile this into some other format somehow or how do I get it to work?

  • Help needed with Flash AS2 to AS3 conversion, having major problems...

  • Is it possible to have non-English regional settings with English day/month names?

    - by Indrek
    I live in Estonia where most regional settings (number, currency and date formats) differ from those used in English-speaking countries. For instance, decimal symbol is comma, thousands separator is space, date format is day-month-year, etc. However, if I set my regional settings to Estonian, then day and month names are also shown in Estonian everywhere: This is slightly annoying since the language used for the rest of Windows is English and I'd like the day and month names to be consistent with it. Is this possible while still keeping the local regional settings? One workaround I've tried is to set regional settings to, say, English (UK) and then customise them to match Estonian settings, but that messes up alphabetic sorting - accented letters like "ö" and "ä" are no longer distinguished from their non-accented versions, and "z" is sorted as last rather than at its correct position in the Estonian alphabet (between "s" and "t"). OS is Windows 7 Professional, in case that matters. Edit: alternatively, if there's no built-in way to accomplish what I want, is it possible to create a custom set of regional settings (like one can create custom keyboard layouts)?

  • Exclude an input language from Alt+Shift/Ctrl+Shift switching cycle on Windows

    - by Headcrab
    I have 3 input languages installed on my Windows 7: English, Russian and Japanese. So when I switch between them by Ctrl+Shift, they go like English - Russian - Japanese - English - ... I don't use Japanese much, but still need it occasionally. Is there a way to somehow exclude it from the "Ctrl+Shift cycle" without uninstalling it from the system? E. g. Ctrl+Shift will be like English - Russian - English - ..., while I still could switch to Japanese by a dedicated keyboard shortcut, say, Ctrl + 3? That extra Ctrl+Shift to go through Japanese just to switch between English and Russian is very annoying, and using Ctrl+1, Ctrl+2, Ctrl+3 for each input language isn't very ergonomic, either.

  • ctrl-c, ctrl-v not working on Windows 7

    - by Beth
    I'm trying to use my Windows 7 PC, and for some reason, Ctrl-C to copy and Ctrl-V to paste only work intermittently. I have a third-party clipboard viewer installed, so I can see when Ctrl-C doesn't copy to the clipboard (there's no new entry) and also when Ctrl-V pastes glarp (the cursor moves, sometimes several lines) instead of what's on the clipboard. I've checked the keyboard and mouse drivers, run a system scan, checked the event log and a bunch of other things I've seen online, and haven't found a resolution. Any other ideas for things to check or try?

  • Ubuntu server hangs on reboot "could not stat resume device file"

    - by matnagel
    Instead of booting into the running system this machine stops and on the terminal I can see a message: could not stat resume device file /dev/sdb5 When I attach a keyboard and press enter the boot continues and the machine comes up like normal. But it's essential that this machine comes up under most circumstancs alone. There never was something like a "resume" on this machine. I tried several times to reboot, but this does not happen on all boots, I can not find a pattern here. There is a software raid running on the box. This is the syslog during boot: http://privatepaste.com/ff0fd0a51c/sdabfjahfgasjkgfu4gfsdzjcgfafasdjfhgasdcjfgauzfgafasgdufzg How can I get rid of this boot failure? We do not need resumes and best would be something that works here and now.

  • Shadows vs Overloads in VB.NET

    - by serhio
    When we have new in C#, that personally I see only as a workaround to override a property that does not have a virtual/overridable declaration, in VB.NET we have two "concepts" Shadows and Overloads. In which case prefer one to another?

  • SQL Server Configuration Manager menu won't show up

    - by Aurelien Gasser
    I'm running a Windows 8 VM on a MacBook using Parallels Desktop 9. On this Windows VM, I have a SQL Server instance running perfectly. However, when I launch SQL Server Configuration Manager, and I want to enable an IP configuration, the Enable menu options are invisible : Here is a screenshot : http://i.imgur.com/PY7qGup.png (I don't have enough reputation to display the image inline) When I click the arrow, a contextual menu should appear with 2 choices "Yes" or "No". Instead, a tiny contextual menu appears, but it's empty. I tried using my keyboard tab/space/arrows keys without success. Has anyone faced/solved the same problem ?

  • QValidator for hex input

    - by Evan Teran
    I have a Qt widget which should only accept a hex string as input. It is very simple to restrict the input characters to [0-9A-Fa-f], but I would like to have it display with a delimiter between "bytes" so for example if the delimiter is a space, and the user types 0011223344 I would like the line edit to display 00 11 22 33 44 Now if the user presses the backspace key 3 times, then I want it to display 00 11 22 3. I almost have what i want, so far there is only one subtle bug involving using the delete key to remove a delimiter. Does anyone have a better way to implement this validator? Here's my code so far: class HexStringValidator : public QValidator { public: HexStringValidator(QObject * parent) : QValidator(parent) {} public: virtual void fixup(QString &input) const { QString temp; int index = 0; // every 2 digits insert a space if they didn't explicitly type one Q_FOREACH(QChar ch, input) { if(std::isxdigit(ch.toAscii())) { if(index != 0 && (index & 1) == 0) { temp += ' '; } temp += ch.toUpper(); ++index; } } input = temp; } virtual State validate(QString &input, int &pos) const { if(!input.isEmpty()) { // TODO: can we detect if the char which was JUST deleted // (if any was deleted) was a space? and special case this? // as to not have the bug in this case? const int char_pos = pos - input.left(pos).count(' '); int chars = 0; fixup(input); pos = 0; while(chars != char_pos) { if(input[pos] != ' ') { ++chars; } ++pos; } // favor the right side of a space if(input[pos] == ' ') { ++pos; } } return QValidator::Acceptable; } }; For now this code is functional enough, but I'd love to have it work 100% as expected. Obviously the ideal would be the just separate the display of the hex string from the actual characters stored in the QLineEdit's internal buffer but I have no idea where to start with that and I imagine is a non-trivial undertaking. In essence, I would like to have a Validator which conforms to this regex: "[0-9A-Fa-f]( [0-9A-Fa-f])*" but I don't want the user to ever have to type a space as delimiter. Likewise, when editing what they types, the spaces should be managed implicitly.

  • How to open Firefox's "organize bookmarks" from Vimperator?

    - by Igor Popov
    Before using Vimperator, I used Xmarks for organizing and synchronizing bookmarks between computers. Now I installed Vimperator and I can only bookmark a page from command mode with :bmark. How can I open Organize Bookmarks with Vimperator? Besides disabling Vimperator and choosing it from the menu what else can I do? Before, I had CTRL + SHIFT + b to open the organizer. Now, in Vimperator, this shortcut doesn't work anymore, even after temporarily disabling Vimperator with CTRL + z. EDIT After setting the main menu visible (with :set go+=m thanks to Hamish Downer), I saw the shortcut for opening the organize bookmarks dialog (CTRL + SHIFT + o). I recently switched to Ubuntu Linux and in this version of Firefox some keyboard shortcuts are different then in Windows (including the shortcut for opening organize bookmarks). Sorry for my ignorance.

  • copy/paste on MacOS gets 'Stuck'

    - by bmargulies
    SnowLeopard. I commonly use copy in a terminal window to grab stuff I have to paste. A few times in the last few days, the clipboard has gotten 'stuck' on some old text. I do the copy gesture (with keyboard or Edit menu) in the terminal window. I paste somewhere else, and get something other than what I just copied. If all else fails, I can always tell the terminal to write it's content to a file and use that. But I'm wondering if there's something I'm doing to get into this pickle and if there's any way out.

  • Laptop screen turns off on removing power cord

    - by YatharthROCK
    After a recent upgrade to Windows 8.1 Pro from W8, my laptop's screen turns off as soon as you remove the power cord. It turns back on with no issues when you plug the power back in. Keyboard and mouse input is processed while the screen is off. My settings tell the screen to go off after 2 minutes of inactivity on battery. I was having a battery issue from before where my laptop would should down after 5 minutes of running on battery (despite showing 60% left), but I think that's unrelated. Any other info will be provided on request. Can anyone help me figure out what's going on? How can I stop this behaviour?
