• Switch monitor configurations on Windows 7

  - by Horst Walter

  I use one of my PCs for flight simulation as well as for home theater. In case one it has 2 monitors attached, and in case 2 (home theater) a HD TV is being used. All 3 monitors are attached at the same time to the graphics card. How could it best switch best between different configurations. In case 1 I'd like to have the configuration with monitor 1/2, alternatively I'd like quickly to switch to another config only with the HD TV as primary screen. A similar question has been asked 6 months back with no full solution yet, so I come up with it again. The comment there of Darius (Windows + P key) is the best so far.

• Encrypt shared files on AD Domain.

  - by Walter

  Can I encrypt shared files on windows server and allow only authenticated domain users have access to these files? The scenario as follows: I have a software development company, and I would like to protect my source code from being copied by my programmers. One problem is that some programmers use their own laptops to developing the company's software. In this scenario it's impossible to prevent developers from copying the source code for their laptops. In this case I thought about the following solution, but i don't know if it's possible to implement. The idea is to encrypt the source code and they are accessible (decrypted) only when developers are logged into the AD domain, ie if they are not logged into the AD domain, the source code would be encrypted be useless. Can be implemented this ? What technology should be used?

• Uninstall SQL Server 2005 Express after Demoting the DC

  - by Walter Aman

  A Windows Server 2003 SP2 hosting a now orphan installation of SQL 2005 Workgroup was pressed into service as a DC in a disaster recovery scenario. It has since been demoted. The server also hosts legacy apps for which we lack reinstallation resources; thus our desire to preserve it as close to intact as possible while removing the orphaned roles. All efforts to remove SQL 2005 thru Control Panel and ARPWrapper /remove fail with error 29528. Should I abandon this and leave the orphan SQL dormant, or is it reasonable to remove it post-demote?

• Still no external sound after installing ubuntu 10.04

  - by Walter

  As suggested I upgraded. Same as before except now not even the speaker control in the application bar. Please help. Background: I have Ubuntu 9.10. Headphones appear to work fine. External speakers - nothing. There are so many sound preferences I have no idea what or which combination. Went to terminal and ran alsamixer which seems to recognize my sound card, though the driver is not listed in System Administration Hardware Drivers; the only driver listed is my graphics card. Setup: I have a Dell 8250. Speakers are plugged into the SB live card. Woofer and 2 speakers using transformer.

• Green bar on top of every (web) video, distorted colors too

  - by Walter Maier-Murdnelch

  Hey since a few days I have a problem with some videos I watch on the web (youtube, vimeo etc). There is a green bar on the top of the video and the colors are distorted, it looks like they are somehow shifted. I am not sure since when this problem appeared, I guess it might have been an update for the flash player. Anyways, I found a workaround. Disabling the hardware acceleration helps. right click on video - settings - disable hardware acceleration. After reloading of the page the green bar is gone. The problem is taht this setting doesn't seem to be persistent and so I have to disable it again on every other video. How can I make this setting permanent or how to get rid of the green bar alltogether? (I will add a screenshot later)

• How to version large binary files?

  - by Walter White

  I run Windows XP inside a virtual machine for some tasks. I attempted to use git to version the image for virtual box; however, it is about 6GB after all the service packs. I only have 6GB of ram and git bombs out saying it is out of memory. I would basically like to have snapshots of Windows so that I can simply blow away an image and start anew when I want to. I like to have something I can rollback to in the event that an upgrade doesn't work so I would prefer to use version control or snapshots if the filesystem supports it. Any ideas on what tools I can use to do that?

• Win 7: Are motherboard / chipset drivers part of the Software Update?

  - by Horst Walter

  Is the Windows 7 update automatically updating Chipset and motherboard drivers? I am basically talking about mainstream boards / processors (ASUS; Intel, AMD, ...), so the question reads "in general". Certainly there are exotic system not updated automatically. This is a duplicate of dangling Will Windows 7 Update Find Chipset Drivers? (one answer, no acceptance, comment directly questions the answer). I am interested in this topic as well, so I dare to ask the question again.

• Is it a good Idea to switch to a SSD to use less battery?

  - by Walter Maier-Murdnelch

  I am thinking of buying a SSD for my laptop, mainly for the purpose of extended operating time when running on battery. At the moment I use a Hitachi HTS545032B9A300 (320GB) (Datasheet) as main drive and a Seagate Momentus 5400.3 120GB as secondary drive. I dualboot Windows and Linux but I don't need the windows partition any longer, a 120GB SDD would be more than sufficient space-wise. Speed is not an issue for me, I make heavy use of tmpfs (ramdrive) within Linux and transfers of bigger files are mainly through some network filesystem anyways, thus a cheaper SSD should do. For the purpose of comparison I chose the OCZ Vertex Plus 120GB. Power consumption always is a big promotional thing the industry uses to make me want to buy their SSDs, some sheet on the OCZ page provides an astonishing comparison of desktop HDDS and SSDs. The numbers I got comparing my laptop HDD and their SSD were not really astonishing any longer. Hitachi 320GB HDD: Startup (W, peak, max.) 4.5 Seek (W, avg.) 1.7 Read / Write (W, avg.) 1.4 Performance idle (W, avg.) 1.3 Active idle (W, avg.) 0.8 Low power idle (W, avg.) 0.5 Standby (W, avg.) 0.2 Sleep 0.1 OCZ 120GB SSD: 1.5W active 0.3W standby I see that there are differences, but actually they don't seem that high as I though they were. And compared to the power consuption of the rest of my system I wonder if it makes a difference at all. Have I just taken the wrong look at the whole thing or may I be better off to buy another battery for my laptop?

• Can all notebooks record from the sound card?

  - by Stefan Walter

  Is it possible that a modern notebook (say built in the last 5 years) contains a (onboard) sound card that it is not possible to record from? I've always assumed that this is a very basic capability, but since I can't get it to work, I would like to check that before I put any more effort into it. In case it matters, my notebook is an ASUS UL50VT, I'm trying with Sound Recorder and Audacity under Ubuntu, but I am, at this point, not asking for "Try that"-support or software recommendations.

• No External Sound

  - by Walter

  I have ubuntu 9.10. Headphones appear to work fine. External speakers - nothing. There are so many sound preferences I have no idea what or which combination. Went to terminal did alsamixer seems to recognize my soundcard, though the driver is not listed in system - admin -hardware drivers, the only driver listed is my graphics card. I have tried several forums and it seems no one is interested in responding to sound issues. Here's hoping it is different here.

• CMD: Append to path without duplicating it?

  - by Horst Walter

  For one CMD session I can easily set a new path: SET PATH=%PATH%;"insert custom path here" Doing so in a batch file does not consider whether the custom path is already included. How do I avoid duplicating it (i.e. check whether it is already contained in the PATH "string"). Remarks: Related: How do I append user-defined environment variables to the system variable PATH in Windows 7? Related: How can I permanently append an entry into the system's PATH variable, via command line? Same question for UNIX: Add directory to $PATH if it's not already there

• Windows: Is there something to see and remotely control single(!) windows on a remote PC?

  - by Horst Walter

  Is there something where I can see and control single(!) windows of PC1 on PC2 remotely. Basically like it is possible with X-Windows. I am not talking / asking about A software which displays the whole desktop remotely (like VNC, Windows RDP). A X-windows server for windows, to connect to Linux. The answer here ( Windows Remote Desktop Connection for just a single window (or a single program) ) requires Windows Server 2008. I need to run this on two Windows 7 machines. Example: PC1 shows three windows, and I transfer, see, and control window 2 on PC2. -- Edit -- I have checked whether there is an X-Server for Windows <- Windows. But there seems not to be one other than Unix <- Windows: http://stackoverflow.com/questions/40453/what-is-a-good-and-free-x-server-for-windows

• Why obfuscating a serial number of a device? What is the risk?

  - by Horst Walter

  In one of my xx.stackexchange questions I've got an answer, in which the user has obfuscated his disk's SN (serial number). Recently I have seen this in several photos as well, the SN was blurred out. I' am just curious, because I have never paid attention to this. What could be the potential risk in publishing a device's SN? I do see some sense when it comes to a MAC address, OK, this could be used for tracking. But a SN of a disk, iPad, whatsoever? Maybe there is an important reason for not publishing it, which I haven't seen so far.

• Win Server 2008 R2 SP1 Repair Disk

  - by Horst Walter

  Is there nothing like "creating a repair disk" for Win Server 2008 R2 SP1. Or am I just missing it? Under Win7 I do just enter "Repair" and it finds "create a repair disk". Sorry - but I am not a professional Admin. Just using the server for my development environment. If there is no repair disk, is there something similar or something I should create in case I do have a system failure? Sure, a full backup is done, but anything else?

• git - recover deleted files from a prior commit

  - by Walter White

  I accidentally deleted some files in a prior commit and would like to recover them. How can I do this? I ran this and found exactly what I was looking for: git whatchanged --diff-filter=D At the time I made the commit, I should have committed the new/changed files only and ran a reset --hard then to recover the missing files. I have about 100 files that I need to restore. I don't want to do a straight revert as that will also undo the changes in that commit. Any ideas?

• Free space on SSD (over provisioning) per disk or per partition?

  - by Horst Walter

  It is recommended to keep some percentage of an SSD free for relocation ( Is free space required on a SSD for performance? ). However, is this rule meant per partition or per disk (whole SSD)? So, if I want to keep 20% free for performance reasons, is it acceptable if one partition is 95% filled, while another is almost empty and the overall empty disk space still is 20. Or does each partition has to fulfill the rule of 20% empty space?

• Why can't my FreeBSD 6.1 (vmware player client under Win7) do DNS in Bridged mode.

  - by Walter Stickle

  I have a 64-bit FreeBSD 6.1 client, running under Windows 7 (64-bit) via VMWare player 3.0, with networking set to bridge mode. DHCP goes fine on boot... I get correct adress/gateway/nameserver info... I have good connectivity to the world in that I can ping any host I can name by IP addr, (including both of the nameservers in resolv.conf,) ...but I can't resolve any names. Inside the Windows box, the network interface has VMWare Bridge Protocol enabled, and the windows side of things has full connectivity. dig replies with: ;; connection timed out; no servers could be reached ...even if I use "dig @server_ip_addr" to point it at a pingable, working nameserver If I set VM networking to NAT mode, I can get outbound connectivity (with happy DNS) but, of course, can't do INBOUND connectivity, which I need. Thoughts?

• Doing a large number of upserts as fast as possible

  - by Jason Swett

  My app (which uses MySQL) is doing a large number of subsequent upserts. Right now my SQL looks like this: INSERT IGNORE INTO customer (name,customer_number,social_security_number,phone) VALUES ('VICTOR H KINDELL','123','123','123') INSERT IGNORE INTO customer (name,customer_number,social_security_number,phone) VALUES ('VICTOR H KINDELL','123','123','123') INSERT IGNORE INTO customer (name,customer_number,social_security_number,phone) VALUES ('VICTOR H KINDELL OR','123','123','123') INSERT IGNORE INTO customer (name,customer_number,social_security_number,phone) VALUES ('TRACY L WALTER PERSONAL REP FOR','123','123','123') INSERT IGNORE INTO customer (name,customer_number,social_security_number,phone) VALUES ('TRACY L WALTER PERSONAL REP FOR','123','123','123') So far I've found INSERT IGNORE to be the fastest way to achieve upserts. Selecting a record to see if it exists and then either updating it or inserting a new one is too slow. Even this is not as fast as I'd like because I need to do a separate statement for each record. Sometimes I'll have around 50,000 of these statements in a row. Is there a way to take care of all of these in just one statement, without deleting any existing records?
