Can I create a barrier between monitors in a dual monitor setup?

2012-05-28T04:58:45Z

We have a Windows 7 laptop that is hooked up to a projector for running slides. I really want to be able to put a barrier between the laptop's display and the projector (which acts as a second display) so that you can't move the cursor to the projector screen. Is this possible?

Broadband gets disconnected after some service fails

2012-05-28T04:33:48Z

I have Windows XP installed on my computer which has some issues due to which "DHCP Client" service often fails, earlier I could rectify this just by starting the service, however recently I switched to broadband connection (from earlier "WiMax" one), and now even after I restart the service (after it stops), connection doesn't work and the only resort for me is to restart my computer. I suspect it might be due to some other service, but I am not able to find it.

Any help will be most appreciated

bash script to remove select files

2012-05-28T03:53:29Z

I have a series of files that are named according to field.%d.vtk and are generated when I run a C++ code. The codes does a series of computation inside a for-loop and dumps the output whenever i%N == 0 where i is the loop variable and N is a constant. By mistake I have set N = 1 and now I have huge amount of data that I do not need. I also do not want to rerun the code.

How can I write a bash script to only keep every N files, delete the rest, and rename the remaining files such that numbers in field.%d.vtk are contiguous? Sorry if this is trivial, but I have very limited experience with bash scripting.

EDIT: When N=1 (by mistake) range of %d would be in [0, 1, ..., O(100,000)] (really large) a suitable N is something around N=100 which would shrink down the number of files to O(1000) or so.

Thanks

Dell XPS L502X intermittent wireless connectivity

2012-05-28T04:29:54Z

I bought this laptop around 5 months back, and it was working fine till yesterday when I realized that the wireless network adapter keeps on releasing the wireless connections in a few seconds(say 30 seconds).

I suspect that it can be the power saving scheme where it was set to save maximum power when on battery. I changed it to maximum performance. I believe this will solve the problem.

But please suggest if anything else can be done or anyone has faced any such issue.

USB webcam just works once and next time I've to reboot

2010-03-05T11:27:00Z

I'm using Ubuntu 9.10, and a usb webcam that is shown as 'Bus 001 Device 005: ID 0ac8:3450 Z-Star Microelectronics Corp.' by lsusb.

The problem is that on connecting the cam, it just works with the first program I start (skype, tokbox, messenger), and if I disconnect it or switch to another program, it stops to work and I have to restart my computer to make it work again.

Has anyone else noticed this behaviour? Is there some good solution to reset the camera without rebooting to make it work again?

Uninstall drivers on an orphaned hard drive

2012-05-28T03:23:25Z

Basically, I need a hard drive (originally from a computer I no longer have) to work on new machine.

What I need from the drive is the configuration of the software installed, not the data.

It has Windows 7 installed but with the drivers for the old machine's hardware. And booting into the drive in a new machine causes an expected BSOD and restart cycle as the hardware has dramatically changed.

How do I uninstall the old drivers from that hard drive? Or better: what's the best way to transfer a drive to a new machine that is not similar to the old one?

Already tried: System Repair via repair disk (says it could not repair), and Safe Mode (it just restarts anyway).

iPhone - Where is the brightness/backlight level setting in the file system? [migrated]

2012-05-28T04:15:22Z

I have an iPhone that was dropped in water. Once the backlight level goes below a certain point, the screen is completely black/useless. I need to go in iFile or some other file system browsing software to set the brightness level to 80% or something high. I've looked around and found the backlight level for SB Settings but I'm not sure if that will work. Anybody know where that setting is?

What does the Boot Camp Assistant do to my drive that I can't just do with Disk Utility?

2012-05-28T04:15:13Z

What I understand is that Windows 7 will not install on GPT (GUID Partition Table) drives. Of course, all new Macs have their drives partitioned that way, and when you run the boot camp assistant, it is taking advantage of the GPT to resize your main partition on the fly and free up some space for the Windows installer to create an NTFS partition.

Of course, it doesn't wipe out your disk and repartition with MBR (Master Boot Record) since all of your data is intact at the end. So, what is going on outside of resizing the startup volume to allow Windows to install itself onto a drive that is in fact GPT-based?

Second: It's easy enough to use Disk Utility to resize your main partition an leave free space. Is it possible to "manually" do whatever else Boot Camp Assistant is doing to prep the drive for Windows?

How to disable middle button showing a page thumbnail in Adobe Reader?

2012-05-25T22:36:48Z

Middle click and drag in Adobe Reader scrolls the page, as it does in most Windows applications. However, middle click and release (without dragging) shows a page thumbnail.

Is there any way to turn off the thumbnail-showing behavior? It's annoying when I just try to scroll the page and suddenly a box pops up, obstructing the text.

Popular Windows SFTP clients [closed]

2012-05-28T03:59:30Z

Seeking some input from the superuser community about popular Windows SFTP clients (admittedly I'm secretly hoping to learn about new and obscure new products that are not on my radar.)

Ideals:

Runs on Windows XP and later
Handles queues relatively well without unpredictable errors
Handles unicode without issue

I'll start it off with a few favorites. Upvotes shall serve as votes (I don't know if this is against the rules — I hope not!)

Unable to download Adobe Premiere Elements v10 trial

2011-12-27T08:16:41Z

I've been trying to download the trial of Adobe Premiere Elements v10 for hours, and it's driving me crazy. I tried both Adobe Download Manager and direct links (file and extractor, found here), and both fail.

Adobe DLM tells me there was an error 101 (which is supposed to happen when no more disk space is available, which is not the case for me), and WinRAR gives me a CRC check error on the directly downloaded archive.

Is anybody experiencing the same issue? Are Adobe files corrupted, or is the problem on my side? What can I do to fix it?

Where does Google Chrome store search engine settings?

2012-05-28T03:41:37Z

I want to know where Google Chrome stores its search engine settings for the Windows XP platform. The reason being; my search engine keeps being changed to SpeedBit and I've thought of just locking up the file to prevent Write access to it. It would only be read-only, on the system level so hopefully that should prevent the annoying search engine change that's happening.

Read OS X partition from Windows 7

2009-07-18T10:38:03Z

I have installed Windows 7 onto my Macbook using Boot Camp, but i find the whole experience very quiet seeing I cannot access my music that resides on the OS X partition. Is there software out there that allows me to read (and maybe write) OS X file systems?

Although free is always proffered, as long as it isn't expensive, I am not against forking out a couple bucks to buy quality software.

It would be very good if the partition would show up the same as any other partition so I can navigate it using Explorer or any other software.

Is there a way to install Windows 7 on MacMini without Bootcamp?

2012-05-28T03:35:09Z

I want to install Windows 7 on the MacMini (2007 era, 2GB, Core2Duo, 80 GB HDD). I'd like to do so without BootCamp. In other words, I'd like to completely get rid of Mac OS from the hard drive.

There is already a similar question, but it deals with booting Windows directly from an external drive. I'd like to take it to the next level.

View information about shared resources

2012-05-28T03:33:06Z

I am currently running file server on Windows 2003 server to allow access to my shared folders.

I understand that there are following to view the various information.

(1) Sessions (net session) - Contains information about all network users who are connected to the computer.

(2) Open files (net file) - shows inforamtion about all the open files (files that are currently acessed)

I would like to know if there is any log file keeping track of the above information ?

How to better copy&paste big files over RDP?

2012-05-28T02:06:20Z

Recently I was making a few attempts to copy&paste a big (1.2 GB) file to remote computer over RDP. The remote computer is virtual testing machine with MS Windows Server 2008 Datacenter.

First I tried to copy&paste before midnight when the transfer speed was limited by client computer ISP to 100 kB/s. So, it required a few hours and I was forced to cancel transfer since remote desktop became too unresponsive and sluggish (slow). So, I re-started it over midnight when my local transfer speed is over 4 GB/s.

So, my impression is that independently on speed (broadband) of copy&paste transfer the remote computer becomes sluggish while copying over RDP. At the same time downloading from internet doesn't make remote host sluggish.

AFAIU, it is because clipboard of remote computer and so its memory becomes overloaded by transfer.
How can I control (restrict) the usage of clipboard for specific process (pasting of file)?

What are the possible way to control it?

Update:
After reading that slow speed of transfer is caused by encryption used for copy&pasting over RDP and since I believe I am more interested in overall efficiency: both the time, or rapidness, of getting file as well as possibility to work without waiting, I changed the question title from:

How to control the usage of remote desktop clipboard usage for pasting a big file?

How to better copy&paste big files over RDP?

For example, is it better to copy&paste one huge (zip) archive or unzip it and copy paste a folder with unzipped files?

And more exactly I wanted to ask:

What are possible ways to improve overall experience:
- the speed of transfer (i.e. availability of needed file)
- responsiveness of remote host (making remote coputer available for work before completion of copy&pasting)?

Package .exe application to run on a Mac

Broadcomm WIDCOMM A2DP Quality Adjustment

2009-09-22T18:17:48Z

So I got a sweet pair of bluetooth A2DP headphones for a sweet, sweet price (Motorola A805, if you were wondering). They sound great paired with an iPhone.

However, when I pair with a computer using the latest and greatest WIDCOMM drivers, the quality is quite poor, almost un-listenable... clicking, popping, scratching. The remedy on one machine was using BlueSoleil, another bluetooth stack, as there is an adjustment for the Bitpool settings that allow you to jack the quality up. Sounds great. However, the bluetooth chipset in my other machine is not supported by BlueSoleil... so I'm stuck with the WIDCOMM stack.

So the question is... Is there an undocumented way to turn up the quality for A2DP in the WIDCOMM drivers?

first question on SU, usually lurking on SO.. =]

Is there a way to make the current active application stand out on OSX?

2012-05-28T03:16:15Z

I've just switched to a double-display configuration, and I still make mistakes regarding which is the current active (focused) application. Is there a way to get the active window to be highlighted?

(Or for example, have the other windows automatically turn transparent?)

How to make a custom screen saver in Windows 7 - with time and calculated text?

Is something like this possible ?

Outlook Signatures for Plain Text and HTML

2012-05-22T02:16:21Z

Is it possible to have Outlook pick a signature to use based on the email style formatting (HTML or Plain Text)?

For example if it was HTML the company logo will show, if it isn't the company name will be written in plain text.

Or maybe force all emails to be sent as HTML?

Obtain file access permissions on read-only-mounted volume? (Windows 7)

2012-05-27T16:15:11Z

I made an image of my entire C:\ drive using EaseUS Todo Backup Free, before formatting and setting up a new Windows (7 Professional) system. I can mount that image read-only in Todo Backup and copy over a few files which I need, everything fine up to here.

Problem is, I need to access some of the files in C:\Users\dvrcoder files on that image. I can't access them since they are owned by the "old" dvrcoder user (whose SID was different than the new one on the new Windows system). I also can't obtain ownership of the files, because the mounted backup image is read-only.

Can I somehow "connect" to the drive using a different SID? Or mount it in a different way? Or make a new user with a SID corresponding to the old one? Or access the files in some other way?

Any help is appreciated, thanks.

Why making a new new partition cause the hard drive to turn into dynamic drive?

2012-05-28T02:49:04Z

So, I was trying to make a new partition using the Windows 7 built in Disk Manager on a HP desktop computer with Windows 7 pre-installed and stuffs. When finishing the new partition wizard, there is an alert saying something like "you won't be able to boot from partitions other than the primary boot drive" and something about "converting into dynamic". I didn't know what it means, so I clicked "no". I tried the wizard again, and the alert shows again, and I clicked "yes" this time.

So, looks like the damage is done, the whole hard drive turned into dynamic. After some google searches, I find out that converting it back to basic is not a click away task, and I can't install Ubuntu on a dynamic drive either (which was my intention at the first place).

I want to know why does this happen. And after converting it back to basic drive, will it guarantee me to create new partitions safely in the future without the risk of turning into dynamic drive again?

How to configure 'local' DNS?

2012-05-27T22:23:54Z

I'm setting up an Ubuntu Linux server on an old machine I have at home [never done this before] and am starting to get things working how I'd like. One thing I'm stuck on is:

How do I get my box's 'name' to resolve to it's IP address? I can access it fine at the minute with 192.168.0.8, but if I type servername in my address bar, it cannot be found. This works for other PC's on the network (Windows), but not my linux server. What do I need to configure to make the boxes name resolve to it's local IP?

Thanks.

PDF Viewer on Windows

2009-07-15T07:26:00Z

I've tried Foxit and Adobe's reader, but I'm not satisfied with either. Foxit has update nagging for non-critical junk. Adobe PDF reader is bloatware. Are there other options you people like?

Weechat - ignore IRC messages based on contents

2012-05-28T02:37:01Z

As stated above, I'm trying to figure out how to ignore messages in a buffer based on the contents of the message (NOT based on hostmask, user nick, etc.) Preferably, this would be able to utilize regex, but even ignoring based on single words would be fine.

Is there a plugin or way to do this in weechat itself? I've been looking around and can't find anything.

How to enable Windows 8 File History for all files?

2012-05-27T09:42:36Z

Windows 2008 and Windows 7 had Previous Versions feature which consisted in keeping the previous versions of files and allowed the user to restore them or copy the previous versions to a different location.

Windows 8 introduces the File History feature which replaces, if I understand well, the Previous Versions feature of Windows 7. File History enables the user to keep track of files in libraries, desktop, contact and favorites.

What if I don't want to keep track of the files on my desktop, etc., but want to keep track of any file on a specific, non-OS, partition? Is it still possible, either by changing some hidden feature of File History, or by getting back the Previous Versions feature, or Microsoft broke it definitively?
