• What are the "N" versions of Windows 8?

  - by Gustavo Gondim

  Microsoft just released the final Windows 8 versions for MSDN members, before its consumer release in october. Anyway, I am a MSDN member. Today I went to see my downloads page and I found a list of the new versions to be downloaded. Windows 8 Windows 8 N Windows 8 Pro Windows 8 Pro N Windows 8 Enterprise Windows 8 Enterprise N I know the difference between the versions "Windows 8", "Windows 8 Pro" and "Windows 8 Enterprise", which you easily find at wikipedia. But, I really need to know the difference between these versions and the "N" versions before download one of them.

• Bonjour/DNS Service Discovery queries

  - by senloe

  I'm trying to implement dns service discovery in my application (no, I'm not asking for a programmatic answer). What I believe is one of my big pain points is generating the query. I know I need to send out a multicast broadcast on port 5353 and want to look for devices of type _ipp._tcp and _print._tcp, but I don't know what the question section needs to look like. For example, in SSDP I sent out a query that looks like the following: "M-SEARCH * HTTP/1.1\r\n" "HOST: 239.255.255.250:1900\r\n" + "MAN: \"ssdp:discover\"\r\n" "ST: urn:schemas-upnp-org:device:Printer:1\r\n" "MX: 5000\r\n\r\n" From what I know about a DNS query I need to send something like: "_ipp.tcp,all,all" but I know there needs to be more. Any pointers to documentation, etc would be greatly appreciated! update rfc1035 appears to contain promising information re the message structure.

• Coloring The Z Shell[closed]

  - by Richard

  Because I have to stare at my command prompt all the time on my computer, it should look at least half-decent, so I am trying to get it colored. The expected outcome is as seen on this site. I have the colors I want set in my .Xdefaults file, but they of course do not color my prompt. My .zshrc is Phil's Prompt. My .Xdefaults is: *background: #121212 !black xterm*color0: #353535 xterm*color8: #666666 !red xterm*color1: #AE4747 xterm*color9: #EE6363 !green xterm*color2: #556B2F xterm*color10: #9ACD32 !brown/yellow xterm*color3: #DAA520 xterm*color11: #FFC125 !blue xterm*color4: #6F99B4 xterm*color12: #7C96B0 !magenta xterm*color5: #8B7B8B xterm*color13: #D8BFD8 !cyan xterm*color6: #A7A15E xterm*color14: #F0E68C !white xterm*color7: #DDDDDD xterm*color15: #FFFFFF *foreground: #DDDDDD Help will be appreciated.

• Default browser hangs

  - by Craig Hinrichs

  Intermittent hangs would occur when I would use Internet Explorer to open a new main page or new tab to a site I know would be up. The browser would open and say "Waiting for site example.com" and do nothing more. If I closed the window and reopened it it would immediately connect. Over time I would have to close and reopen the window to get to the page. This would happen to any page, including Google. Got sick of it and started using Chrome. I recently upgraded my anti-virus and am now experiencing the same issue with Chrome. I use AVG for my antivirus. Empirically it seems that if I don't make Chrome my default browser I don't experience the issue. I tested this theory for over two hours yesterday. Possible issues I have found this could be but not confirmed yet: MTU settings are not correct. I am infected but my antivirus has not caught it (unlikely but possible) ?? I would like to think this is related to my antivirus but I am unsure how to verify. I don't like the idea of killing my antivirus if #2 is a possibility. I am looking for tips on how I can troubleshoot possible issues.

• ssh X11 forwarding issue

  - by bbuser

  I have put ForwardX11 in my ~/.ssh/config and then I start a X11 application like this: ssh -f user@host 'someapp; sleep 1' This works fine. The application someapp has a button which opens a viewer application via a shell script viewer.sh. When I press the button the viewer comes up. This is all good and as expected, but if I do ssh -2 -f user@host 'someapp; sleep 1' there's trouble. someapp starts very well, but if I click the button the viewer doesn't show up. As the viewer is called via a shell script, I replaced the call with xclock and the situation was exactly the same - I think the viewer is not to blame. The situation is the same on Linux and AIX. The reason I need -2 is that I finally want to use connection multiplexing and this does only work with version 2. The reason for the sleep 1 is that it didn't work otherwise;-) To add more confusion, with ssh -2 -f user@host 'xterm &; app; sleep 1' the viewer works as long as the xterm is open. When I close xterm ssh -v outputs the following debug1: channel 1: FORCE input drain debug1: channel 0: free: client-session, nchannels 3 debug1: channel 1: free: x11, nchannels 2 and from that moment the viewer doesn't show when I press the button. I also replaced the viewer application with a script that writes the $DISPLAY variable to a file. The variable is always set correctly.

• Wi-Fi performance in Windows 8 RP on a MacBook Air (mid 2011)

  - by Steven Lu

  I was able to install the Boot Camp Windows software using the executable that it provided, and there are no unrecognized or unknown devices in Device Manager. Wi-Fi works but it seems to be limited to an extremely slow 1.5Mbits. Network Center reports an 802.11n connection (at 65Mbps usually) but transfers never reach above about 200kB/s. Being limited to 1/20th of the connection speed of my internet service is quite frustrating. Does anybody experience the same issue? I have been trying to identify the Broadcom Wi-Fi chipset and a driver that I could try to upgrade to but I have made very little progress on Google on this front.

• Are HDMI to VGA Adapters Really Device-Specific?

  - by allquixotic

  There are a lot of devices on the market right now (especially mobile devices) with a Micro-HDMI or Mini-HDMI port and no VGA or D-Sub output. Most manufacturers of said devices sell a cable that looks something like this: I have yet to find a cable like this that claims to work on a wide array of devices. In general, these cables claim to work with one specific device only. The way these cables work, I think, is that analog VGA signals are sent from the HDMI port on the device. This should work for devices that have special hardware on the motherboard/GPU capable of driving this. Is it the case that these cables have to be custom designed for each device? Or, is it rather that any device which possesses this special "signaling of analog VGA over the HDMI port" can be made to work with a cable that is physically compatible (i.e. the HDMI end plugs into the device and the VGA end accepts a VGA monitor cable)? Note that I am not looking for a product recommendation, just a conceptual clarification on what exactly these devices are doing. Also, a few remarks: The cables like the one depicted here are not digital to analog converters. I know about these: they are expensive, and they are the ONLY solution if your device only outputs a digital signal and is incapable of driving analog VGA over the HDMI port. The cables like the one depicted here are not straight crossover cables from VGA to HDMI, either. The crossover cables are designed to send a digital HDMI signal over the VGA port's wires; that is, the wire protocol is HDMI (digital) but the physical pinout is the same as VGA, even though nothing analog is happening. Once again, this is not the behavior that, I believe, the devices which I'm talking about in this question are doing. The cabling and devices that this question is about transmit the analog VGA data over the HDMI port (the HDMI port is in the device outputting the data, and the VGA side is the monitor/projector).

• Facebook Chat through XMPP protocol on Pidgin Portable - Will not Authorize

  - by Sara Neff

  I heard you can use facebook chat on desktops now. Thats awsome! What i didn't hear is that it is a pain in the butt! Not awsome! I've followed six nearly identical sets of instructions from six different websides, including the one that facebook generates for you, to get facebook chat connected through Pidgin. Its the latest portable version, so from what i hear the plugin is out of the question. Whenever I go to try and connect i get a message saying "Not Authorized" and buttons to either modify the account info, or retry. NOTHING i have done has fixed this, and I can't find anything remotely usefull anywhere. I am running windows xp, and running pidgin (portable) off of a flash drive. Someone please tell me what i have to do. I read about authorizing the chat on my actual facebook page. I'd have tried that if i could find out how to do it, but if its there they hid it good. HELP?!

• Nokia 5800 v50, getting "Invalid server name" with ad-hoc wlan with Windows 7

  - by Krunal

  After upgrading to v50 firmware in my Nokia 5800 xpress music phone. I am not able to connect to ad-hoc wlan network in my laptop(Windows 7 OS). I have a dialup internet connection and created wireless ad-hoc network to access the internet in my phone. But I am getting "invalid server name" in the phone and my wireless network access type in Windows 7 shows "no internet access". I am able to connect to wlan infrastructure network using 5800 in my office. So my phone is working with wlan and I m able to access internet on it. BUT The problem is "dial up with ICS enabled" and "AD-HOC wlan network" in Windows 7. Can anyone give some solution on it. Or can you provide a guide/tutorial to connect 5800 with adhoc network and dialup internet in Windows 7. System: Windows 7 Dial up internet connection with ICS enabled. Ad-Hoc wireless network with WEP Nokia 5800 Xpress Music phone Note: I have read other posts also and tried their solutions but didn't worked for me. the first solution is to bridge the network and access it. but how can I bridge the dialup and wlan netwok? second solution is manually configure IP and DNS addresses in phone. But what should I add as IP and DNS as my dial up and adhoc network have automatic addresses.

• Is there a reason to use library backups if I'm backup up full disks?

  - by Ben Brocka

  In Windows Backup I can backup libraries or whole drives (or specific folders). I want a complete backup of all relevant drives. After selecting the drives, there's still the option to backup libraries: Is the backup going to do anything different if I include libraries as well as drives? Should I just backup the whole drive instead? Space used by the backup shouldn't be an issue, since I know the incremental backup is pretty smart..

• Intel VT-x disappeared after upgrading to Windows 8

  - by StepTNT

  I've upgraded to Windows 8 some weeks ago (MSDNAA!) and today, while I was trying to run a VM, I've noticed that VT-x is disabled. Now, Hyper-V works without problems, as I've tried emulating Win7 and WP8; but VirtualBox says that VT-x is disabled and it can't run my VM. Just to double check, I've run Securable by GRC and the Intel utility and both says that I've got VT-x off. Here comes the problem: VT-x is ON in my BIOS, and it worked flawlessly before upgrading to Windows 8! Any kind of suggestion? EDIT: My CPU supports VT-x: http://ark.intel.com/products/52219

• some clarification on accept field in http request

  - by Salvador Dali

  Can anyone enlighten me on the following question: What do different fields in accept field in HTTP request mean? I can understand the basics that through accept the client is telling the server what type of information it is waiting to receive, so for example: Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 This way the client will tell the server that it can understand three following formats: text/html application/xhtml+xml application/xml But can someone tell me what this q values mean and that / Also if I have any flaws in my understanding - please tell me.

• How do I stop MSYS from transforming my compiler options?

  - by Carl Norum

  Is there a way to stop MSYS/MinGW from transforming what it thinks are paths on my command lines? I have a project that's using nmake & Microsoft Visual Studio 2003 (yeecccch). I have the build system all ported and ready to go for GNU make (and tested with Cygwin). Something weird is happening to my compiler flags when I try to compile in an MSYS environment, though. Here's a simplified example: $ cl /nologo Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 13.10.6030 for 80x86 Copyright (C) Microsoft Corporation. All rights reserved. /out:nologo.exe C:/msys/1.0/nologo LINK : fatal error LNK1181: cannot open input file 'C:/msys/1.0/nologo.obj' As you can see, MSYS is transforming the /nologo compiler switch into a windows path, and then sending that to the compiler. I really don't want this to happen - in fact I'd be happy if MSYS never transformed any paths - my build system had to take care of all that when I first ported to Cygwin. Is there a way to make that happen? It does work to change the command to $ cl -nologo Which produces the expected results, but this build system is very large and very painful to update. I really don't want to have to go in and change every use of a / for a flag to a -. In particular, there may be tools that don't support the use of the - at all, and then I'll really be stuck. Thanks for any suggestions!

• Focus issues in OSX Spaces

  - by AK

  Spaces rarely returns focus to my last used window. Haven't been able to peg universally reproducible steps, but spend any time switching among spaces and windows and you'll come across this. It often happens with finder windows. I'm thinking this is because osx treats Finder as a single app, so bringing finder forward in one space brings it forward in all spaces. Extremely annoying! Anyone have a fix for this?

• Completely remove user account and create another with same name in Windows 7

  - by TeaJay

  Here's my question simply and then the details in case they help to get me an appropriate answer. Question: How can I completely and permanently delete a user account in Windows 7 so that I can create another one with the same user name without the computer name extension added, eg Jane Smith not Jane Smith.computer name? The details: I just did a clean install of Windows 7 Professional 32 bit. (My laptop crashed, I reinstalled Vista and restored backup files but things weren't working so I decided to just get Windows 7 since I had to start over anyway). I used Windows Easy Transfer to save just about everything, even customizing to include a user's appdata from Windows.old which was created when I reinstalled Vista -- not knowing that another windows.old file would be created with the installation of Windows 7. After installing Windows 7, I used Windows Easy Transfer to transfer the user file, appdata, to the new user account which I gave the same name (Jane Smith) in case having a different name would cause problems with reading files or something. Afterwards, I realized that I did not want ALL of that junk. So, I thought no problem, I'll just delete the user account I just created, nothing lost, and create another one this time transferring only the files I wanted (using the customize option in windows easy transfer). I wanted to keep the same user name, e.g. Jane Smith, so after I deleted the user account I checked the files, and I didn't see. It was late so I went to bed and the next morning I created a new user with that same name (Jane Smith). The files looked fine if I remember correctly. Meanwhile, I updated the computer and it restarted a couple times. As I was moving files to the "Jane Smith" user account file, things weren't working as they should. I was actually moving files to the deleted user account and that the current user account was named "Jane Smith.computer name" and that's where the files needed to go. I don't like this. It's too confusing. I want just "Jane Smith". How can I do this without just changing the user name (which doesn't change it in the file path etc)? I want the first one GONE. If I can't do this, is it a problem to create an account with another name and still transfer files to it without path or other problems? I hope this question makes sense and that someone can help me. Thank you in advance!

• Firefox requests the master password twice

  - by Mehper C. Palavuzlar

  I've set a master password for Firefox. When Firefox starts, it strangely opens two separate password request windows. When I type in the master password and hit enter, Firefox opens without problems, but the other password request window stays there. I simply close it but it's annoying. Why are there 2 windows as it's enough to type the password once? I've upgraded Firefox from 3.5.5 to 3.5.6 but the problem remains. Any comments? PS: The latest news from this issue can be followed from the related Mozilla Support Forum.

  I am using a Dell E6500 laptop with windows XP on it, it was originally tagged/installed with Windows Vista. My issue is, when I close the lid, it will not either Hibernate or Standby. If I close the lid with either of these options, I then have to startup from scratch, and anything I had open is not open. I just want to close the lid, have it keep what I have running, not use power util I open the lid again and start it up (with the stuff still open I had open of course). Suggestions?

• Converting text file to epub?

  - by jamesh

  I have a bunch of book length text files I'd really like to read on my EPUB reader (as it happens FBReaderJ). What would be the best route to convert them? I have access to OSX and Linux (Ubuntu). Probably happiest with a command line, but would setting for a GUI for batch conversion. My criteria for success are really based upon the shortfalls I have found with Calibre must do the whole book at least a guess of what the title/author may be. Minimum the source filename for the title. hygienic with files it uses - tidies up after itself (this is less important) doesn't try to be an all-in-one library manager (again, less important). is lenient in parsing special characters (e.g. < and & characters).

  I'm looking for a Gnu/Linux package manager, that can help to package, distribute, install sofware (actually scientific libraries), like this: do not required root privilege, for example, install in $HOME/opt or $HOME/local manage muliple version of a library, for example, with this directories organisation: $HOME/opt/somelib/4.2.1/lib/ $HOME/opt/somelib/4.2.1/include/ $HOME/opt/somelib/4.2.1/bin/ $HOME/opt/somelib/4.2.2/lib/ $HOME/opt/somelib/4.2.2/include/ $HOME/opt/somelib/4.2.2/bin/ $HOME/opt/anotherlib/1.0.0/lib/ $HOME/opt/anotherlib/1.0.0/include/ $HOME/opt/anotherlib/1.0.0/bin/ package contains source files, not binaries, build is performed during install. support for Mac OS X too would be good. Then it's up to the user to manage it's LD_LIBRARY_PATH, or compile with -L/good/path etc. Does it exists?

• Change DPI setting in Windows 8.1 for the Logon Screen

  - by jmc302005

  How can the DPI setting be changed for the Logon Screen in Windows 8.1? Microsoft has added per-user DPI settings. But this means that there is no adjustable DPI setting for the Lock/Logon screen. You can change the DPI setting to be the same across all displays and this does affect the icons and font on the lock/logon screen. However, it does not affect any app/program that can run on the lock/logon screen. Ex. I use a 44" flat screen TV for my monitor on my desktop. Big enough for me to sit in my recliner and use my computer. I use the on-screen keyboard most of the time. (I don't want to keep a keyboard next to me.) The problem is that with the new DPI setup the on-screen keyboard takes up nearly half the screen, which is too big. I tried looking through the registry to see if I could find a setting for it. In the key HKEY_USERS\.DEFAULT\Control Panel\Desktop there is a string value named LogicalDPIOverride with a value of -1. I have a feeling this is where I can fix the issue. I tried changing the value to 0 and to 1 with no change in the result. Instead I noticed that after logging out and back in the -1 value was back in the registry. How can I change this default DPI? Can I use the LogPixels string that worked for DPI in Windows 7? Here are two Screen shots, one of the Lock Screen and one of the Logon Screen:
