• Calibrating Displays in Boot Camp 3.0 on MacBook with external display

  - by Brian Reiter

  The LED display on my MacBook Pro is very blue-ish without correction. In OS X the advanced mode of the display color calibration tool is excellent and I can largely color-correct the display. Windows 7 incorporates a color calibration tool but it is less powerful. It largely consists of a software gamma correction tool and color charts to use with the hardware controls on your display (which don't exist on a notebook or an apple external display). How can I color-correct Windows in Boot Camp to match the OS X correction without using a Spyder or other special calibration hardware?

• Keeping new Ubuntu installation's /var on separate drive without formatting

  - by tlayton

  I have a server running an older version of Ubuntu and with /var stored on a separate partition on a separate hard drive. I am attempting to update Ubuntu to 10.04, but I still want to store /var on a separate partition and hard drive. However, I don't want to format the drive which currently contains /var, as it has important data. Is there some way to have 10.04 set up the new /var on this separate drive at installation, without formatting the drive and losing the old /var?

• What parts should I get for an ASRock x58 Extreme motherboard

  - by Brad Gilbert

  I just received an ASRock x58 Extreme motherboard, for my post on this question. It was a 2009 Tom's Hardware recommended buy. It is a Core i7 motherboard, with an X58 Express Chipset. It uses DDR3 RAM. What I want to know is, what parts should I get to finish it off. I'm looking for some good bargains, because of a lack of funds. The most taxing game I will probably play on it is OpenTTD. The only parts I currently have that are compatible: A Dynex 400W power supply. It appears to be an ATX 2.1 power supply, with the addition of a -5 rail. Apparently designed to be compatible with most ATX-style motherboards. Several PCI add-in cards. Mostly 10/100 Network cards Some sound cards Some video cards with a VGA connector Plenty of PATA drives. 8 GB - 80 GB Hard-drives A dozen or-so CD-ROM drives, only a handful of them are CD-RW drives. One DVD-ROM drive I have one LCD, with a 15 pin VGA connector, which I salvaged from the dump. The only thing wrong with it was some dead capacitors. It also has a stuck pixel.

• Do the amount of CUDA cores matter for Sony Vegas

  - by Saif Bechan

  I am building a new PC, and I am wondering if I am making the right choices. The PC will mainly be used for video editing, and mainly in Sony Vegas. Now I have the choice of going with a video that that has more of less CUDO cores. To be precise I am choosing between a Ti and non-Ti version of an nVidea video card. Now I have read that sony vegas can partially use the CUDA cores to it's benefit, but not that much, and only if you use GPU acceleration. On the other hand I have heard it's better to leave GPU acceleration off as it will effect the quality of the output. Making it so that the CUDA cores actually don't make much of a difference after all.

• Music Nav Doesn't Work After Installing IntelliType

  - by Lynda

  I have started using a Microsoft Sidewinder X4 Keyboard. It came with the Microsoft IntelliType Pro software. Since I have installed the software I am not able to change my music via the play | previous | next buttons at the top of the keyboard. I use iTunes and not Windows Media Player. How do I solve this issue? Here is a screenshot of the Keyboard Properties: Note: I am on Windows 8 using iTunes 11. Uninstalling the IntelliType software is not an option as I use the macros.

• Cannot activate Windows 8 build 9200

  - by Luke Puplett

  I'm running an MSDN build 9200 of Windows 8 N (Europe), and thought it was the RTM - I don't go for beta OSes, generally speaking. Anyway, this gold code version runs a watermark, which makes me suspicious. I can't activate it. It just maintains the message: Windows can't activate at the moment. Try activating Windows later. If this issue persists, contact your system administrator or technical support department for assistance. So I phoned myself and the guy at the other end was useless, kept talking over me. Should I be able to activate this build or did I download the wrong version? Luke

• running chkdsk on a disk without a drive letter

  - by neubert

  I have a hard drive that shows up in Disk Management as having two partitions. One of the partitions says 69.71GB and that's it. The other says 4.82GB and, underneath that, Healthy (OEM Partition). I'm trying to do chkdsk on the 69.71GB partition and am unsure of how to do it without a drive letter. Any ideas? It's an NTFS partition that's gotten corrupted. Linux's ntfsfix spits out a bunch of errors so I'm thinking chkdsk might be better. Thanks

• Macbook Pro 2.66 GHz vs. 2.8 GHz

  - by nevan

  Is there much advantage in getting the higher end Macbook Pro compared to the mid-range one? The differences between the two are: 2.66 GHz vs. 2.8 GHz 256 MB graphics memory vs. 512 MB 3 MB L2 cache vs. 6 MB 320 GB hard drive vs. 500 GB $2000 vs. $2300 I've looked around, but I can't find any direct comparisons for the two machines. I'd be using the machine for development. I generally use a computer for 3 years. I don't really play games, but do use Photoshop regularly. I've heard that once Snow Leopard arrives, the graphics chip will be used to boost the main processor, so I was wondering if getting the one with more graphics memory would be an advantage?

• What causes Windows Media Player on Windows 8 to not play the entire library?

  - by somequixotic

  Behavior 1: Verify that the WMP playlist is clear of all songs. Turn on the "Shuffle" and "Repeat" features. Double-click on a music track in the Library. Click the "Next" button (double right angle brackets). A random song from any track in the Library is randomly chosen and played. When observing the Playlist (clicking the "Play" tab), the entire contents of the Library appears in the Playlist. Behavior 2: Verify that the WMP playlist is clear of all songs. Turn on the "Shuffle" and "Repeat" features. Double-click on a music track in the Library. Click the "Next" button (double right angle brackets). The button visually depresses like it has registered the click, but nothing happens. Absolutely nothing. Moreover, the "Previous" button is grayed out. When observing the Playlist, only the one song that was double-clicked appears in the Playlist. What causes Behavior 2? I cannot correlate any specific action I've taken with Behavior 2, and Behavior 1 has been the case as long as I can remember, all the way back to Windows XP. Even earlier during my usage of Windows 8, I recall Behavior 1 working correctly. But suddenly, inexplicably, without changing any settings in WMP, Behavior 2 kicked in, and persists after reboots. I've tried sfc /scannow in an administrator prompt. All system files are in order. I've downloaded all Windows Updates and driver updates. I've attempted to alter WMP options and playback settings to no avail. So... what is causing Behavior 2? Is this an intended, valid behavior, or is something malfunctioning? How would I know what that "something" is? How would I go about fixing it without just reinstalling Windows 8 fresh?

• Disable a Section of the Mousepad?

  - by Shahmeer Navid

  I purchased a hp envy 4 ultrabook. Its great but I'm infuriated at the touchpad. The click buttons and the touch pad are combined together but the click button area is touch sensitive. I usually rest my thumb on the right click but the mouse cursor goes completely crazy on this machine. Is there any way to disable a section of the touchpad? Basically make the click button area have nothing to do with the pointer function. I did see this post: Disable touch pad for mouse button region on new HP pavillion models? but the solution presented in that only limited the area from which the touchpad can begin. Since I rest my thumb on the click buttons, I would like to completely disable the click button area of the touchpad. Thank you.

• How do I increase my home's bandwidth?

  - by Derek

  I just mistakingly posted this on Stack Exchange but don't know how to delete it... Anyway, I was thinking of building a home server to use instead of renting a VPS, because in the long run it would be cheaper. What I'm concerned with is the bandwidth limit of my house. I know when I'm downloading something off the internet, if I download at high speeds the rest of the computers connected to my router will become slower. Is there any way to avoid this? There are other cable outlets in my house, will connecting a modem and router there avoid this problem?

• TvTuner as webcamera

  - by BarsMonster

  Hi, I have decent TVTuner which can capture both analog signal & HDMI. I am able to connect my camera and see output of it in realtime in VirtualDub. I want to be able to use it in Skype and other software which use webcams. The problem is that they only use first "videoinput" of my videodevice, but HDMI is 3rd, and there is no interface to switch (in Skype for example)... So could you suggest any "proxy" software which can take video from Tuner, and show as a webcam?

• Dual HDMI input - HD Video Capture Card

  - by Shivan Raptor

  Any suggestion for HD video capture card? Here is my requirements: I need 2 HDMI input for 2 HD Camera the signal captured will be encoded with Adobe Live Encoder (does it support dual input sources? I do not require mixing of 2 sources) the encoding format will be H.264 (720p), then will be sent to Adobe Flash Media Interactive Server for LIVE broadcasting. http://www.blackmagic-design.com/products/intensity/ I found the one above online, but I am not sure about its performance, and it has only 1 HDMI input. If I plug 2 of them into my workstation, will it conflict with each other?

• Powerbook G4 unresponsive on wake?

  - by David

  I have a Powerbook G4 17" and I recently updated to the Mac OS 10.5.8 and got a monitor. I put it to sleep by closing the lid and sometimes it resumes normally and sometimes it doesn't. It doesn't matter if it's on sleep for a day or 10 minutes, it just happens randomly. It wakes up, but the screen doesn't flash blue for a few seconds like it normally would, indicating that it found the second monitor. It just wakes up, and a picture appears on both screens and the mouse moves, but nothing responds. The only way I can make it work again is by holding down the power button until it shuts down and then turning it on again. this frustrating because then I have to reopen all my programs and Safari tabs. I tried resetting the PMU by unplugging everything and taking out the batter, then holding the power button for five seconds, but it has the same problem no matter what I do.

• How not to show user name beside each consecutive message

  - by Joce

  After years on GTalk, I recently switched to Pidgin for my IM needs. Almost all is ok with me, though there's on thing that bugs me. It shows the name of the author beside each consecutive message. e.g. joce: Hey joce: Long time no see! joce: How are you? Bob: Hey! Bob: Indeed! Instead of (as it is in GTalk): joce: Hey Long time no see! How are you? bob: Hey! Indeed! Is there a setting that I've missed or a plugin that could do that for me?

• Windows 7 playback of dvr-Microsoft files stutters

  - by Jim Lynn

  I've just had to install Windows 7 on my Media Center machine because my Vista installation had a faulty drive. I've got the latest drivers that I can find - Intel 945GM integrated Graphics, Realtek audio drivers. Things are working OK with one exception. Playback of old recordings, from dvr-Microsoft format files, is choppy. The picture freezes for a fraction of a second, then quickly catches up. The sound is uninterrupted and doesn't pause. These freezes happen once every 5 seconds or so. It's very regular. Playback of Live TV from the digital tuner is perfectly smooth. DVD playback is perfectly smooth. As an experiment, I used the MPEG editing package VideoReDo to create a small test file in three different formats. This program takes the raw MPEG streams and repackages them into the desired container. I took the same clip and created three files in three formats: dvr-Microsoft (Microsoft's old recorded TV format); mpg (standard MPEG); and ts (raw MPEG transport stream of the kind often produced by PVRs). When these three files are played back under Windows 7, the mpg and ts files play smoothly, but the dvr-Microsoft file stutters. The last piece of data I have is that two other Windows 7 machines can play back dvr-Microsoft files smoothly with no stuttering. One is a netbook, with less grunt than the media centre. So there must be something specific about my Media Center machine that's causing the problem. Does anyone have any idea where I can look now? I don't know much about AV software, codecs, filter graphs etc. but I suspect that's where the problem lies. Rendering the video isn't the problem, but extracting the streams is. How would I go about diagnosing the problem? Edited to add: I just used the GraphStudio tool to look at the filter graph on the offending PC. The filter graph it uses by default for dvr-Microsoft looks identical to the other machines, and, interestingly, when I play the files using GraphStudio they run smoothly. Under Windows Media Player and Windows Media Center they stutter. I'd like to see the filter graph for Windows Media Player but GraphStudio won't show it. It looks like Windows Media Player and WMC are using a different decoding path to GraphStudio. Edited again to add: Today I purchased a new HDTV. The same Media Center driving the TV at 1080p is now playing back the old Recorded TV files smoothly, without stuttering. So whatever the cause of the original problem, using a different resolution seems to have removed the problem. It might also explain why nobody else has had this problem. I doubt many people use Media Centre with a 14in portable TV.

• No compatible network card

  - by sbintcliffe

  Motherboard: Asus K8N-E Deluxe with onboard NIC (nVidia nForce) Secondary NIC: I've tried using a standard NIC (Device Manager displays this as D-Link DFE-538TX 10/100, but under manufacturer in the General tab of the properties in Windows it states Realtek Semiconductor Corp.) I have downloaded ESXi 4.0.0 build 208167 and cooked to disc. I've booted from it, the .TGZ modules load from the yellow and grey screen, the progress bar reaches to about 60% and like a second later the screen changes and I have the following information on screen; "No compatible network adapter found. Please consult the HCG." I've checked the HCG and found that my motherboard is listed. I also get the same message with the secondary NIC. Any ideas please?

• Git pull auto complete OSX

  - by vodkhang

  Follow some instruction on this site http://denis.tumblr.com/post/71390665/adding-bash-completion-for-git-on-mac-os-x-leopard . I can do git auto complete for MAC OS. However, when I type git pull origin ma (for master), and then tab it takes a long time for git to auto complete to become git pull origin master . I think it connect to the server to get the branch, but I am not sure, is there any way to make it faster and only get the branch on local machine cd /tmp git clone git://git.kernel.org/pub/scm/git/git.git cd git git checkout v`git --version | awk '{print $3}'` cp contrib/completion/git-completion.bash ~/.git-completion.bash cd ~ rm -rf /tmp/git echo -e "source ~/.git-completion.bash" >> .profile

• Hide non VHD partitions

  - by James

  Hey! I have two partition on my HDD: C and D. On D: I have a vhd image (with windows 7 ultimate) that I use to boot from. When I'm running the OS from VHD I can still access my physical parititons. Is it possible to dismount them, in order to see just the virtual disks in the VHD OS? I tried with the physical C and it says that I cannot dismount a boot paritition and I think D cannot be dismounted because the VHD is on it.

• Cloning single disk drive to multiple drives simultaneously

  - by mr.b

  Hi, I am looking for a way to clone single disk drive to more than one disk drive at the same time. I have prepared system images on 1TB disks, and it takes almost 2 hours to clone one disk to another, and then it goes up exponentially, in order to have say 30 disks cloned. If it was possible to clone one disk to more than single target, it would simplify whole procedure a lot. Also, is there something that prevents this kind of operation? I mean, is there some special reason why every disk cloning software that I know about supports only single target drive? Thanks!

• KeePass justification

  - by Jeff Walker

  I work at a place that tries to take security seriously, but sadly, they often fail. Currently, one of the major ways they fail is password management. I personally have about 20 accounts (my personal user id on lots of machines). For shared "system" accounts, there are about 45 per environment; development, test, and production. I have access to 2 of those, so my personal total is somewhere around 115 accounts. Passwords have to be at least 15 characters with some extensive but standard complexity constraints, and have to be changed every 60 days or so (system accounts every year). They also should not be the same for different accounts, but that isn't enforced. Think DoD-type standards. There is no way to remember and keep up with this. It just isn't humanly possible, as far as I'm concerned. This might be a good justification of a centralized account management system, a la LDAP or ActiveDirectory, but that is a totally different battle. Currently the solution is an Excel spreadsheet. They use Excel to put a password on it, and then most people make a copy and remove the password. This makes my stomach turn. I use KeePass for this problem and it manages all of my account very well. I like the features like auto-typing, grouping, plugins, password generation, etc. It uses AES-256 encryption via the .Net framework, and while not FIPS compliant, it has a very good reputation. The only problem is that they are also very careful about using randomly downloaded software. So we have to justify every piece of software on our workstations. I have been told that they really don't want me to use this, be cause of the "sensitive nature" of storing passwords. sigh My justification has to be "VERY VERY strong". I have been tasked with writing a justification for KeePass, but as I am lazy, I would like any input that I can get from the community. What do you recommend? Is there something out there that is better or more respected than KeePass? Is there any security experts saying interesting things on this topic? Anything will help at this point. Thanks.
