  • Upgrading my home network to Gigabit Ethernet and Wireless-N turns out slower than before

    - by Raheel Khan
    My home network has three desktops, three laptops and some NAS drives. All desktops and NAS drives support Gigabit LAN and all laptops support Wireless-N. I was running a 100 BaseT switch though. I recently purchased a Gigabit Ethernet Switch and an Wireless-N ADSL Modem-Router. After upgrading, I noticed that the wireless file transfer speeds from laptop-to-NAS and vice versa became terribly slow. Possibly even slower than before the upgrade. The transfer speeds from desktop-to-NAS (wired) have improved though. As an example, copying a 50GB file from laptop-to-NAS was estimated at 15 hours! Is there something I can do to improve this? Also, should I consider buying a dedicated wireless access point for speed rather than using the Wireless modem-router?

  • How to switch to user perspective in Blender

    - by Cyanophage
    I've just started using Blender (v2.63) for the first time. I have used a lot of 3d modelling programs in the past but Blender's controls seem to be set up differently and it's taking a while to get used to it. The thing that is really bugging me at the moment is switching from user perspective to front/side/top views. I have my view in perspective mode and I want to switch to front view in orthographic mode and then switch back to the view I had before. It seems that the only way is to press numpad-0 to go to camera view, rotate the screen a bit to get rid of the annoying black outline and then switch it back to perspective mode. Then sometimes when I go back to front view it's in perspective mode which is annoying as you never want front view in perspective, only orthographic mode. My question: Is there a way I can be in my user view in perspective mode, switch to front/side/top views in orthographic mode and then switch back to where I was before in my user mode and be back in perspective mode?

  • Finding trends in multi-category data in Excel

    - by Miral
    I have an Excel spreadsheet that contains hundreds of rows of data that each represent a single sample in a larger population. Each row is divided into three columns that contain frequency counts of a specific type of thing. Together the three columns summed on a single row represent 100%, though each row will sum to a different value. What I'm most interested in are the proportions of each of these types (ie. percentages of each column relative to the sum of the three columns). I can easily calculate this on a per-row basis, but what I'm really interested in is trying to find an overall trend from the entire population. I don't really spend much time doing data analysis so the only thing I can think of trying is to create those percentage columns and then average them, but I'm sure there must be a better way to visualise this.

  • How can I unlock a folder locked by ‘System’ process on Windows Server 2008?

    - by ripper234
    I'm on Windows Server 2008 64-bit. LockHunter identifies that a folder is locked by the "System" process. I'm not sure why this happens, but my bigger concern is how to unlock it. I'm looking for a solution that can be run from the command line. LockHunter itself is unable to unlock it. Also, Sysinternals' Process Explorer doesn't find the locked folder's handle. Rebooting is not an option either.

  • Can't Get Mac Mini to turn on - no screen, no beep, only the fan, power light, and optical drive noi

    - by pibyers
    I have an Intel-based Mac mini mid-2007 (Model A1176). This is the computer my kids use so I don't use it regularly. The computer had been working fine until one day my kids told me that it no longer works. The computer will not boot up. When I turn it on the fan turns, the white power light in the front turns on, and there is a sound that appears to be from the optical drive (rather than hard drive). I don't get anything to the monitor, nor do I get any dings or other start up sounds from the computer. Here is what I've tried thus far to no avail: 1) Swapped out the monitors early on since I figured that was my weak link - no change 2) Reset the PMU - no change 3) Tried to boot up from the System Disk - The mini loaded the dvd into the drive, but nothing else (I can't eject the disk so I can put it back) 3) Start up the computer in target mode connected to another mac - I tried this too, but I never received a chime or the disk show up on the other mac. I'm about out of ideas apart from scraping the computer. Does anyone have any ideas that I can try? Again, nothing has been done to the computer in at least 6 months when I upgraded the RAM. I'm also still on Leopard. Thanks.

  • perl sorting an array of hashes

    - by srk
    use strict; my @arr; $arr[0][0]{5} = 16; $arr[0][1]{6} = 11; $arr[0][2]{7} = 25; $arr[0][3]{8} = 31; $arr[0][4]{9} = 16; $arr[0][5]{10} = 17; sort the array based on hash values so this should change to $arr[0][0]{6} = 11; $arr[0][1]{9} = 16; $arr[0][2]{5} = 16; $arr[0][3]{10} = 17; $arr[0][4]{7} = 25; $arr[0][5]{8} = 31; first sort on values in the hash.. when the values are same reverse sort based on keys... Please tell me how to do this.. Thank you

  • Add unallocated space to lvm

    - by Newbie
    I shrunk my windows partition and now have 10 GB of unallocated space that I now want to use to grow my / partition which is an ext4 in an lvm. I'm running Fedora 12. I ran system-config-lvm but the "Initialize Entry" button is greyed out. The unallocated space is not adjacent to the lvm but I cannot move the partitions in GParted like I was able to with ext3 in the past. I cannot create a new partition either as it says it cannot have more than 4 primary partitions. I don't see any option to create an extended partition. So my question is, how do I add that unallocated space to the lvm so I can grow the size of the / partition? I don't want to reinstall Fedora.

  • No option to connect to wireless network

    - by Casebash
    I don't have any option to connect to wireless. It just doesn't appear in the taskbar at all - even the no wireless networks were found doesn't appear. In network connections, I only have the option of using a wired connection. According to device manager, I have a working VIA Rhine II Fast Ethernet Adapter (this device only appeared after I selected showing hidden devices). I have already attempted restarting the computer a few times. Does anyone have any suggestions?

  • Windows 7 - Windows get autoselected

    - by DjRikyx
    I have a really annoying problem in Windows 7. I just updated Windows vista to Windows 7 32bit The problem is that every second the top windows is being selected. To explain better what happens: I open task manager and leave it there, then i select a icon on desktop, after 1 second, the icon is deselected and Task Manager windows is selected. Also i see windows borders blinking, every second. This is Annoying, because every time i do a right click or selecting a menu in any application, every second the menu get closed... I do not know what is doing this, i searched in task manager for some 'bad' application running, but seems ok, tried closing all programs but it's still there. If i restart the computer first i don't get that problem, but after a while it start.. I noticed that When using Visual Studio Express 2012, but i don't think is the problem, because also if i close VS the problem remains. Hope you can help me, i'm getting hungry!! It's annoying!

  • Changing Windows public folder in batch script.

    - by Angus
    I've installed Steam on an external hard drive so I can play games on different computers by just moving the drive around. Since save games are often saved in My Documents or AppData, but I want them to move with the external hard drive, I wrote a batch file that sets environment variables before starting steam. setocal set USERPROFILE=%EXTERNAL_LETTER%\Profile\Me set APPDATA=%USERPROFILE%\AppData\Roaming ... start %TARGETAPP% endlocal I'm not sure if this is the right way to do this on Windows, but it seems to work. However, one game saves its games in the Shared Documents folder. I've tried setting %PUBLIC% and %ALLUSERSPROFILE% but that does not seem to affect where the game looks. Is it possible to make this one program use a different Shared Documents folder, either by environment variables or some other means? The change in Shared Documents should only affect the one program, I do not want it to be a permanent or system wide change to Windows.

  • Windows 8.1 clean install keeps failing with Oxc0000005 error

    - by joaocandre
    I'm encountering the error Oxc0000005 when making a clean install of Windows 8.1 x64 on a Samsung 840 SSD. I don't know where the error is coming from, I'v already tested several solutions/workarounds I found online and nothing seems to work. The SSD is healthy, I can install Linux (Ubuntu) on it, but apparently the Windows install reports the drive as "locked" when trying to "refresh" the install. According to diskpart, however, the SSD is not in read-only mode, so I don't understand what is going on. I had Windows 8 installed before formatting the drive.

  • Excel: count number of unique/distinct row in range with condition

    - by Bertvan
    I have a an excel sheet with: in Col A: week numbers in Col B: dates (timesheet entries) I need to know the number of days worked for each week, so I need to the number of unique date entries per week number. I found formula's (both array as non-array) that handle this for a fixed range, but I want to have the results in another column per week number. So, the result of the added dataset below would be (the colon is just for clarity): 14: 2 15: 3 17: 6 20: 2 21: 3 If this is the source data: 14: 4/04/2012 14: 4/04/2012 15: 10/04/2012 15: 10/04/2012 15: 11/04/2012 17: 26/04/2012 17: 26/04/2012 17: 26/04/2012 17: 26/04/2012 17: 27/04/2012 17: 27/04/2012 20: 14/05/2012 20: 14/05/2012 21: 23/05/2012 21: 23/05/2012 21: 25/05/2012

  • How to compare old CPU to new CPU?

    - by Lasse V. Karlsen
    I hope this question doesn't get closed at once :) I have an old laptop, a Compaq NC4200, which is going its final laps around the track these days. Battery is dead, and everything kinda runs slow. It also has only 1GB of memory, and even though I don't know if it can take more, I probably wouldn't be able to get hold of any that matches without having to special order it. The size, however, has been ideal for my usage pattern, so I'm looking to replace it with a similarly sized laptop, at least in the same size category. However, it's been a while since I tried keeping track of CPUs, so I have a question. The old laptop has a Intel Pentium M 760 1.86GHz processor. One laptop I found online has a Intel Pentium SU4100 1.3GHz dual-core. This type of processor seems to be quite common in the price and size-range I've been looking. What kind of relative performance boost could I expect from the old one to the new one? I am not expecting a "about 7.45x speed", but some indication would be nice. For instance, dual-core tells me it might be akin to 2.6GHz, but I assume I can't simply compare 1.86GHz to 2.6GHz and expect the new one to run about 1.4x as fast, I expect more these days. Or is that unrealistic for this kind of processor? Do I need to up my price range and go for a 2+ GHz processor?

  • Using Windows 7 drivers in Windows Server 2008 R2

    - by Robert Koritnik
    Maybe I should post this to http://www.serverfault.com. Windows 7 comes with all sorts of signed drivers so there's high probability that all drivers for your machine will be installed during system setup. On the other hand Windows Server 2008 doesn't event though it's practically the same OS when it comes to drivers. But I know that this has a very good reason. It's a server product, not a desktop one. But the thing is that many power users and developers use server OS on their workstations which are normally desktop machines and would need Windows 7 driver spectrum... Question I know I've been reading about some trick on the internet that first installed Windows 7 on the machine, than do something to get either all Windows 7 driver collection or just those installed, and then install Windows Server 2008 and use those drivers. The thing is: I can't seem to find these instructions on the internet any more. If anybody knows where these are please provide the link for the rest of us.

  • My Windows 8 computer does not come out of Standby

    - by Jikag
    My computer will not come out out of standby. It has had this issue ever since I bought it ~4 years ago. When I purchased it, It came with Vista, I have since upgraded it to 7 and now 8 Pro, each time hoping that it would fix the problem, each time finding that it did not. My computer is an HP Pavilion Model #: m9500y. The computer goes into standby, but does not come out of it properly. If Hybrid sleep in on, it does not respond at all. If Hybrid sleep is off, It comes out and I can see the desktop for a bit, but then the screen goes black again and I have to reboot. I have tried Running a sfc, and a chkdsk in case it's a corrupted file, but it hasn't helped. This isn't too serious an issue because I can just shutdown my computer and turn it on the old fashioned way, but it is annoying and I would appreciate some advice going forward as I'm currently stumped.

  • Browsers not responding

    - by Jesper
    Hello, Strange thing started to happen to my computer yesterday, and I can not recall installing anything new or updating anything the last few days either. It was first the browser, Chromium, that started to freeze up and not respond for ages, say 10 minutes. Then my email, Windows Live Mail client started doing the same thing, I click on an email and the program goes "not responding" for 5-10 minutes. At first I thought it was Chromium, so i reinstalled it but no help, So i installed Opera and thought I would give it t a try, but not same thing is happening to Opera so it is clearly an OS issue or/and internet connection issue. Does anyone know what the problem can be? Im running Windows 7 32bit on a dual core Sony vaio laptop with 4gb ram. There is nothing wrong with the actual internet connection as it works fine on other computers on the network, and the connection it self does not drop. Grateful for any help, Jesper
