• What would be a good topic for research on "edge of multiple processors / computers programming" topic?

  - by Kabumbus

  This is a subjective discussion so we can express our dreams and hopes here. A "topic" must be like a task with point to have as end result a software poduct. A "topic" must be mainly about "Software engineering", "Algorithm and data structure concepts" and perhaps "Design patterns". I mean let us try to look what is not already there? What can be developed in fiew month and give a breakthrue / start a new leap / show somethig not realized before in science of f multiple computers programming? What i see is already there: LAN / wire and other infrastractural programms for connecting on device level MPI/ Bit torrent/Jabber protocols / APIs / servers for messaging on top Boost and analogs on evry OS in most languages for multithreading there are lots of CUDA like on computer frameworks for fast calculating on computers GPUs What I personally do not see out there is a crossplatform framework for multiple processes interaction. Meaning one that would allow easy creation of multyple processes running in paralell inside one hoster app on one machine. In level not harder than needed for threads creation (so no seprate server apps - just one lib doing it all) Is there ny such lib and what can you propose for research topic?

• Windows 7 Long Delay on Login or Unlock

  - by Adam Driscoll

  I have a clean install of Windows 7 x32 running on my HP DV6449us and am experiencing a really long delay (10+ seconds) when unlocking or logging into my computer. The same issue was happening with UAC but I was able to turn that off. I realize this is a security risk but couldn't take it any more. I've read about this being video driver related but have updated the drivers to the newest I could find for the GeForce Go 6150. Anyone else experiencing this? My desktop is very happy but he's sporting a Nvidia 260 GT. Is it just the lack of firepower?

• Map a drive to root of a server (\\sever) in Vista

  - by Andy T

  Hi, In Win XP, I can very easily map a network drive to the root of my NAS server. I browse to it in Explorer (\192.168.1.70), choose "Map Network Drive", choose the drive letter, done. In Vista, this does not seem possible. I have to go "Map Network Drive" from 'Computer', then enter the address, but it will only let me map to specific shares (sub-folders off of the server root) and NOT to the server root share. Since my NAS has built-in shares (music, photo, video, etc.) then I would have to have drive letters for all of these, which I absolutely don't want. Can anyone tell me - how come I can easily map to the server root from XP, but not in Vista? Is there something fundamentally different in the networking across the two OS's? Or do I just need to do things a different way? Hope someone can help. Thanks, AT

• Motherboard warning lights when plugging in a display port cord to graphics card?

  - by rllr

  Earlier today, my computer spontaneously shut itself off and refused to turn back on. I tested my PSU and it's operating fine. I unplugged everything and let it sit for a while and it started to make a high pitched coil whine/hiss. When I came back an hour later and plugged in only the power cord, it turned on without any issues. After some troubleshooting, I noticed my motherboard (Intel D975XBX2) has a red CPU led and VR led that come on whenever I plug my monitor into my graphics card via display port. DVI does not cause a similar issue. I was running three monitors off the card, so I need both DVI ports and the display port working. Is it likely my graphics card needs to be replaced, or should I be looking elsewhere to resolve this issue?

• Update saved password for basic authentication using a script

  - by Kalamane

  I have a website that uses basic authentication as described on this webpage. Each of the computers I manage have the password saved in their browser. There is only one username and password for this. After someone logs in to the site this way, they are presented with their individual username and password prompt as part of the web page. The purpose of the initial username/password is to discourage non-technical employees that aren't supposed to be using the page from even viewing it. So far, when we've had to change this password, I've manually gone to each computer and updated the saved password. I'm writing a startup script to configure other aspects of these systems so that I can maintain them easier. I'd like to be able to update the saved password via this script. The operating system running on these machines is Windows XP SP3 and the browsers they're using to access this site are IE8 and IE9. How can I update the saved basic authentication information for a website via a script?

• Two users using the same same user profile while not in a domain.

  - by Scott Chamberlain

  I have a windows server 2003 acting as a terminal server, this computer is not a member of any domain. We demo our product on the server by creating a user account. The person logs in uses the demo for a few weeks and when they are done we delete the user account. However every time we do this it creates a new folder in C:\Documents and Settings\. I know with domains you can have many users point at one profile and make it read only so all changes are dumped afterwords, but is there a way to do that when the machine is not on a domain? I would really like it if I didn't have to remote in and clean up the folders every time.

• Windows 7 - Remote Desktop - multiple credentials

  - by w-

  Hi, My home network consists of a couple XP machines and a windows 7 box. One of the XP boxes is like a shared server accessed via Remote Desktop. I have an account on there and my gf has another. Previously I was able to save RDC shortcuts to this shared server including credentials. So in order to access the server from a computer on the network, i just needed to open the shortcut. I thus would have two shortcuts, one for my account and one for my gf's. In windows 7, it seems to store credentials for a box based on machine name. i.e. i can only store one set of credentials per machine name. This seems incredibly stupid so my question is: In windows 7, is there some way to have RDC shortcuts that use different credentials to login to the same target box? thanks

But it has a teamviewer client running on it 24*7 to which i do have access(no vpn installed). I can accesss this client from anywhere using teamviewer. I want to know if somehow i can use teamviewer to get a ip/hostname that is accessible from the internet and host a webserver. Also is it possible to get an ip if i get admin access but without opening ports.

• If you develop on multiple operating systems, is it better to have multiple computers + displays?

  - by dan

  I develop for iOS and Linux. My preferred OS is Ubuntu. Now my software shop (me and a partner) is developing for Windows too. Now the question is, is it more efficient to have multiple workstations, one for each target OS? Efficiency and productivity is a higher priority than saving money. I have a 3.4Ghz i7 desktop workstation running Ubuntu and virtualized Windows with two displays, and I'm putting together an even more powerful i7 Hackintosh with 16GB RAM (to replace my weak 2.2Ghz i5 Macbook Pro). My specific dilemma is whether I should sell the first computer and triple boot on the second one, or buy two more displays and run both desktop systems simultaneously. Would appreciate answers from developers who write software for multiple OSes. Running guest OSes in VirtualBox on one system not ideal, because in my experience performance is seriously degraded under virtualization. So the choice is between dual/triple booting on one system vs having two systems, one for OSX+iOS/Windows (dual boot) and the other for Ubuntu (which I prefer to use as my main OS). For much of our work, I write a server-side application in Linux and a client for iOS (or for Windows or OS X) simultaneously.

• Is there a way to have a working search bar in Explorer with Windows Search Service disabled?

  - by Desmond Hume

  I had to disable Windows Search Service (turn it off in Windows Features) for the reason that it was constantly using the hard drive in an excessive way (maybe because I've got very large quantities of files on my PC), noticeably slowing down my computer, and the Windows.edb database file grew way too large, about 2.5 GB in size. But the side-effect of it is that now the search bar is gone from any Explorer window and I miss this useful feature. So my question is, is there a way to stop Windows Search Service torturing my hard drive and still being able to search for files and folders directly from Explorer, perhaps using some third-party software?

• Ubuntu 12.04 LTS - Apple iPad 3 (iOS 7 non-jailbroken) USB connection problem

  - by Eldian

  I've bought an Apple iPad 3 (iOS 7 non-jailbroken), and I'm trying to connect it to my PC running Ubuntu 12.04 through the original USB cable.

• Monitoring User Login time

  - by beakersoft

  Hi, i have recently been given the task of trying to work out why the login time (not machine boot time) for some of our users seems slow. The vast majority of clients (95%) are running on XP sp3, Windows 2003 domain controlers. Most users have the same model of machine. I would like to be able to see how long each of the polices are taking to load (if possable split user and computer) and any other info that might help (services starting etc) I changed the userenvdebuglevel reg option to generate the userenv.log file but it did'nt contain very much info Thanks Luke

• Random shut down? Asus N53J Laptopi

  - by Mr.Y

  My Laptop is pretty new and today it random shut down on its own. I was surfing the net and the computer shut down on its own (Like losing power, without any warning). It was the 2nd time, the first time was 3 weeks ago. Btw it happens during cold days. I remember one time I was unable to turn on my laptop at all. So I'm pretty sure it's not related to heat issue... could it be the laptop is too "cold"? My room temperature is around 17=18 degree on average :P edit -I use Windows 7 Professional. -I run memtest86 once and it passed. -I run my laptop WITHOUT battery all the time.

• IPSec on Domain Controllers and Trusted Domains

  - by OneLogicalMyth

  I am looking at configuring IPSec as follows: Isolation Request authentication for inbound and outbound connections Computer and user (Kerberos V5) I am looking to do a blanket deployment across all servers and domain controllers. Workstations I will leave as not set. What impact in terms of the domain controllers with the 2-way forest trust do think I would see? Should I exclude the IP addresses of the trusted domain controllers? I don't want to stop communication between the current and trusted forest, however I do want IPsec to be used within the current forest on all servers. The trusted forest is running 2008 R2 and the current forest is 2012 R2.

• Windows 7 Skype shifts audio to speakers

  - by Greg Reynolds

  I have noticed a strange feature on my Dell Latitude running Windows 7 and Skype. When I am listening to music on the headphones, and Skype rings, then the audio I was listening to is redirected to the computer speakers, while Skype takes over the headphones. This is infuriating as my co-workers are treated to 1 second snippets of whatever rubbish I have on at the time. Any ideas on how to stop this happening? I messed with some of the settings on Skype, but nothing seems to make any difference.

• Ubuntu One has high CPU usage but no syncing

  - by Peter

  over the weekend I updated my computer to Windows 8. So far Ubuntu One was running smoothly, but ever since the update (clean, new install) Ubuntu doesn't sync any more. In Windows 7 it would start to sync at full internet speed as soon as I drop a file. But now in Windows 8, as soon as I drop a new file into the Ubuntu One folder, CPU usage goes up to about 50 % and no network traffic occurs. This stays like that for a couple of minutes, CPU usage goes back to normal and then the client says that all is in sync - which isn't true. Is it too early for Windows 8? Do others have the same problem or is there something I can do about it? I try a couple of different things, and realized that if the file size is 20 MB the files get uploaded. The original file was 1.5 GB. I also didn't work with 200, 100 and 50 MB large files. But even with 20 MB large files, the upload is very slow and not steady. The log give plenty of this error: - twisted - ERROR - Failure: exceptions.TypeError About which I don't know the meaning. By the way, the account works just fine on the Ubuntu 12.04 partition. Any help is greatly appreciated. -Peter

• backlight doesn't work on acer 5732z tried everything I can find

  - by Dude Random21

  Ok if you can solve my problem you're really really good. I want to run ubuntu 12.04 on my acer aspire 5732z I know (from research) that these computer's have issues with the backlight on ubuntu. So I tried a couple of solutions: The "sudo lightdm restart" method. I get no change at all. The "sudo setpci -s 00:02.0 F4.B=30" method. This so far has been the most effective, I first tried it in the F1 console right away I get the screen back, problem is going back to the desktop it goes back to being black. So I tried it from a terminal window and it works as well but as soon as I unplug my external monitor the screen turns black again and doesn't come back. If I plug the monitor back in the screen stays black and the only thing I see is the mouse pointer. From here I go back into console (which I am able to see) and reboot from there. The "sudo sed -i 's/GRUB_CMDLINE_LINUX=""/GRUB_CMDLINE_LINUX="acpi_osi=Linux"/g' /etc/default/grub" method. This one I got no instant change and after reboot still no change. I'm open to pretty much any suggestions you may have.

• Looking for a central image database and tagging system for a group of users

  - by jstarek

  I'm doing IT support for a small volunteer organisation who needs to centrally store and organize around 2500 photos. Can anyone here recommend a database or similar system which matches the following criteria: Intuitive to use for users with little computer experience Multi-user support, ideally with integration in our existing LDAP user directory Should have a web-interface Not a hosted solution like Picasa (because we have a rather slow internet connection with very slow upload) Should allow tagging of images, sorting by various criteria and storing copyright information If there are native GNOME and/or Windows clients for the tool, that would be a great benefit. Many thanks in advance!

• Open NetApp CIFS Share

  - by kingfish

  I have a CIFS share on a NetApp device. I want this share to be completely open to any user/computer on the same network. I don't want any authentication (domain, workgroup, etc) required; no login/password should need to be provided. Currently I have CIFS configured to use "Domain - Windows 2000" authentication and have the permissions on the share set to "Everyone - Full Read/Write" but if you try to connect to it from a machine that isn't bound to the domain it is asking for login info.

• Compressed disk image on Linux

  - by Aaron Digulla

  I just got my new computer with a much bigger harddisk. I think I copied all important files over but just to be sure, I'd like to keep a disk image of my old disk. To save space, I'd like to compress it but I didn't find an option to mount a compressed image. My goals: Result must be easy to access No need to decompress the whole thing before I can access anything Files should be quick to locate - no TAR/CPIO archive Necessary space should be less than just copying the files over So ideally, I'm looking for a read-only, compressed file system which I can create in a file and which grows automatically.

• Uninstalling ATI's drivers and installing NVIDIA's?

  - by whydidithavetobreak

  I replaced my card but I'm not sure how to set things up on Ubuntu. When the computer boots, it doesn't start GDM (I think that's what it's called). Instead, it asks me to log in the command line. If I try to do a startx, it tells me there is no AMD device connected or something to that extent. I originally installed the ATI drivers using the GUI. It said that I was using the limited drivers or something to that extent with a popup on the right of one of the taskbars, so I clicked there and updated it. I think it could also be reached by going to system administration restricted drivers or something close to that. I tried installing the nivida drivers by doing a "sudo apt-get install nvidia-glx-185" and then doing "sudo modprobe nvidia" and "sudo nvidia-xconfig" as this guy says but that didn't work. Modprobe couldn't find anything related to Nvidia and nvidia-xconfig wasn't an available command for me. Since I wasn't sure how to remove the ATI drivers I did that without messing with them. Not sure if that was a good idea.

• Removing partition to install OS?

  - by Shane

  So i have a computer that has 2 hard drives and i installed Ubuntu server on it. I used LVM to connect the two. So i tried to put windows back on it but it failed because it said it couldn't position the drive and then when i booted again the OS couldn't be found. So i booted it with the Ubuntu setup disc but now when it goes to partition it says that the position can not be modified because its already in use. I am asking if there is a way i can just remove everything and start fresh?

• Articles of x386 and later CPU based systems

  - by user32569

  Hi there. I know this is hard question, and possibly not to be answered here, but if there is some article, or more you know about, please post a link. About books, its sad but many great computer books cannot be bought in my country. So, you can find many articles online, which says how memory was mapped back in pre x386 CPU. How there was explicit holes ready for MMIO BIOS, Video BIOS, etc. How there was A20 line for allowing higher memory access etc. Problem is, time changed. Today BIOSes are many times larger, and pure x86 16bit mode is used for booting and ROM flashing only. OS ignore BIOS as they access everything using drivers. And I just want to know, how it works today. I know not so specific question, but I read OS dev wiki, many articles, but all refering to days before massive usage of pure 32bit CPUs.

• Mouse(s) double clicks instead of single click (its not the mouse)

  - by Iznogood

  I am aware of this very similar question: But I have tried with 3 different mouses and everyone of them exibit the same behavior. Simple enough, 1 out of 3 times I get a double click when single clicking). I searched the net a lot about this problem and have yet to find a solution. I have tried: 1- switch to another mouse 2- uninstall the mouse drivers + reboot 3- I do not have any special mouse drivers/software like intellisense and logitecs to uninstall. 4- verified that I was not in fact on some setting that says open files with single click. 5- everything is up to date including a antivirus 6- Installed fresh drivers from dell's website It is a dell vostro 260 computer running windows 7 pro 64. edit: added a 6th thing I tried. edit2: tried reinstalling every windows update I could find nothing Boss just said he'd buy me a logitech mouse hoping the drivers will fix my problems. Hopefuly!
