• Why is my Windows XP not allowing me to turn on sounds?

  - by Rookie

  This started to happen few weeks ago: Every time I start up Windows, the global sound volume is set to muted. I was able to just click the muted button to un-muted and that was fine, until now: Now I cant even click that unmute button! Every time I click the unmute button, I hear a split of a second the music I play, then it stops immediately. It is maybe 10 milliseconds until it mutes it again. In theory I could write a program to click that button continuously, but is there another solution to fix this? Or is this a broken hardware problem and Windows knows it and therefore doesn't allow me to enable sounds or my computer would break apart? Any ideas what could be causing this? A weird virus that's purpose is to piss me off? That weird this whole issue is, really, doesn't make any sense at all.

• KVM Switch for a mac and a Windows (XP or 7) machine to share VDU

  - by Adrian Parker

  Have a MacPro (snow leopard) connected to an (windows standard) Asus 25" monitor via a DVI--VGA adapter. Now the boss wants me to work from home, so I want to share my Asus display with a Windows XP laptop. No doubt once my wife sees this, she will want to do the same thing, but with a Windows 7 laptop. So what I would like, I think, is your recommendations for a KVM switch (or better solution) that allows the Mac and a (windows 7 or windows xp) laptop to share the Asus display. Bonus marks if they can share Apple keyboard and magic mouse, but am quite happy to use separate mouse keyboards. The MacPro is the one that is always connected, the laptops come and go. Any ideas? Thanks in advance for any help.

• How to re-arrange Excel database from 1 long row, into 3 short rows and automatically repeat the process?

  - by user326884

  I would appreciate help on the above-mentioned topic. I am unfamiliar with Visual Basic for Excel, so will need step-by-step guidance (if solution is via Visual Basic). For example :- Row 1, Sheet A: A1 B1 C1 D1 E1 F1 G1 H1 I1 To be re-arranged into Sheet B : Row 1 : A1, B1, C1 Row 2 : D1, E1, F1 Row 3 : G1, H1, I1 The Sheet A (database sheet) has a lot of rows (example 3,000 rows), hence the Sheet B is estimated to have 9,000 rows (i.e. 3 x 3,000). Thanking you in anticipation of your speedy response.

• Javascript Event in Innerhtml Resulting from PHP Server Script

  - by user144527

  I'm (very slowly) making a website, and I'm creating a search engine for the database, which is essential to organize the dependencies during data entry. Anyway, what I would like is to type a few keywords into a box, have a menu pop up with various search results, and have the box fill with the ID number of the selected entry when it's clicked. Currently, I have a document called search.php which fills a div called search-output using xmlhttp.open() and the innerhtml property. Everything is working perfectly except for filling the original search box with the ID number when clicking. My first attempt was to add an onclick event to each entry in the output from search.php. Unfortunately, I found that javascript inserted into innerhtml is not run for security reasons. I've been Googling for hours but haven't been able to find a solution. How can I get the original search text box to fill with the correct ID when I click it? Is what I'm doing a good setup for the results I desire, or is there a better way to integrate search features into data entry?

• Laptop forgets second monitor when it goes to sleep

  - by al c

  I recently updated my nvidia driver... now I have to re-establish the connection to my second monitor everytime the laptop goes to sleep. When I open the NVIDIA control panel, the second monitor is listed there but the checkbox beside it has been cleared. Oddly my laptop screen is identified as display #3 and the external screen as display #4. Is there a registry key that I can clear to get them set back to #1 & #2? Will that fix the problem? Or is there a simpler solution. (It's a Dell Studio XPS laptop with GeForce 9500M running Windows Vista 64-bit) TIA Al

• How do you interpret `strace` on an apache process returning `restart_syscall`?

  - by indiehacker

  We restart an apache server every day because RAM usage reaches its limit. Though of value See this serverfault answer, I dont think lowering the MaxClients in the apache configuration is a solution to the unknown root problem. Can you make sense out of the below data? Below is an extract of what $top with M returns: 20839 www-data 20 0 1008m 359m 22m S 4 4.8 1:52.61 apache2 20844 www-data 20 0 1008m 358m 22m S 1 4.8 1:51.85 apache2 20842 www-data 20 0 1008m 356m 22m S 1 4.8 1:54.60 apache2 20845 www-data 20 0 944m 353m 22m S 0 4.7 1:51.80 apache2 and then investigating a single process with $sudo strace -p 20839 returns only this one line, which is cryptic, for me: restart_syscall(<... resuming interrupted call ...> <unfinished ...> Any insights? Thanks.

• In windows 7, how do I disable "Ease of Access" pop ups on the logon screen as I am typing my password?

  - by Silfheed

  So the question is pretty much in the title. Things to note: 'Use On-Screen Keyboard' is un-checked I have disabled Ease of Access by replacing utilman.exe But my problem now is that when I'm typing my password, It'll stop all together on the 'u' or the 'p' character and I have to click on the ease of access button then move focus back to the password to continue. Yes, one obvious solution is to not use a password that has 'u' or 'p' in it (which I've done), but that's obviously not a completely satisfying answer. Thanks! I feel a tumbleweed badge...

• Distributed filesystem for automated offline data mirroring

  - by Petr Pudlák

  I'd like to achieve the following setup: Every time I connect my laptop to a local network, my partition gets automatically mirrored to a partition on my local server. I only want to mirror what has changed from the last time. (I understand that it is not a proper backup solution since there is no history of the changes, it'd be more like a non-persistent network RAID.) Is there a distributed file system that allows such a setup? I've done some searching and it seems to me that most distributed file-systems are focused on data availability and distribution, not duplicating them. I'd be thankful for suggestions. Edit: Sorry, I forgot to mention: I'm using Linux.

• Textmate: Find and replace across project with contents of one file from said project

  - by griotspeak

  I have a regular expression to find the text I want (I wrapped the relevant section in custom tags), and I can do it by hand without much issue, but what I want is a way to automatically find and replace throughout the entire project. A macro seems like an OK idea, but it would be nice to have a command (to edit and tweak). sed seems like a good bet, but I am pretty unfamiliar with it. I am not so much asking for a complete solution as I am asking for an example that does something close to what I want. I don't really know of a good way to start.

• Are there any good resources for refactoring existing C# code to use LINQ while keeping your tests passing?

  - by Paddyslacker

  I've been teaching myself a little LINQ and an exercise I thought would be useful was to take my existing Project Euler C# code, which I built using Test Driven Development and gradually convert it to LINQ. I realise that LINQ is not always the best solution for all of the Project Euler problems, but I don't want to get into that here. I'm wondering whether or not it's feasible to refactor "traditional" OO C# code to use LINQ and functional programming syntax whilst keeping all of your tests passing. I can't find a way to make the tiny steps I'm used to making using TDD when converting to LINQ and this is a roadblock for me. I seem to have to make large changes to come up with a single function that I then replace whole chunks of my code with. I realise I could write this from scratch in LINQ, but in the real world, I'd like to be able to replace parts of my existing C# code to take advantage of LINQ where appropriate. Has anyone been successful with this approach? What resources did you find useful for refactoring existing C# code to use LINQ whilst taking a Test Driven Development approach?

• Linux foxboard network monitor

  - by het.oosten

  I want to use a Foxboard a simple network monitor for multiple routers (all routers are connected to the internet). Foxboard is a mini pc with an embedded version of Debian. My idea is to use multiple virtual network devices like this: eth0 192.168.2.10 eth0:1 192.168.3.10 eth0:2 192.168.4.10 I found a nice Python script to ping an external host here (the solution from Ryan Cox): http://stackoverflow.com/questions/316866/ping-a-site-in-python Is it possible to configure Debian to use eth0 when I ping www.site-a.com and eth0:1 when I ping www.site-b.com?

• Ubuntu 12.04: Unable to add or delete a user named 'mysql'

  - by Afaque H

  I am trying to install MySql on Ubuntu 12.04 but the installation is failing with the error: "Can't change to run as user 'mysql'. Check if the user 'mysql' exits." So I go ahead type in the command : 'cat /etc/passwd | grep mysql' and result is null. I try to add a user 'mysql' by issuing the command 'useradd mysql'/. But it fails with the message: 'useradd: user 'mysql' already exists'. When I try to delete the user 'mysql' using the command 'userdel mysql' it also fails with the message "userdel: cannot remove entry 'mysql' from /etc/passwd." Can anyone explain me what's going on and suggest a solution.

• Force Windows 8 Metro apps to run lower resolutions below 1024x768?

  - by piokuc

  I have installed Windows 8 Consumer Preview on my Samsung NB30 netbook. I was very excited to try it on this little box cause it has a touchscreen and Windows 8 is supposed to be optimized for touchscreen devices. The installation was quick and smooth and all the drivers seem to work well including the one for the touchscreen. There is one major problem, though: when I try to tap one of the tiles on the Metro UI it displays This app can't open. The screen resolution is too low for this app to run. The machine has Intel Atom N450 processor and Intel GMA 3159 integrated graphics card and has maximum resolution 1024x600. I've read that Metro requires at least 1024x768. Is there a solution to this problem? Is there a way to force Windows 8 Metro apps to run in lower resolutions?

• Determining the State of a User using their Hostname

  - by PhpMyCoder

  Not sure if this is the right SE site. I figured this question doesn't belong on SO, but if you think it doesn't belong here either, I apologize. I've been looking into determining the location, specifically the state, of a user accessing my website. One of the options I've known about for a while is the GeoIP City Database, however this isn't the most cost effective solution and I'm cheap so I was looking for a less expensive way. Something that occurred to me was that my state was in the public hostname assigned to me by Comcast: (Dash Separated IP).hsd1.ma.comcast.net Could it be possible that other ISPs follow this same pattern of inserting the state abbreviation into their users' hostnames? I've been looking around for a list of hostnames for other ISPs, but I haven't found anything. Can anyone verify that this holds true for other major ISPs?

• Manipulating Exchange 2003 shared contacts folder remotely

  - by andybak

  I've got a CRM web app running on a remote server that needs to synchronise it's contacts with the in-house Exchange 2003 shared contacts. Exchange 2003 doesn't appear to support web services. What would the typical approach to this problem be? My initial instinct would be to open port 80 on the Exchange server, run a simple webserver, POST to it and then control Exchange via OLE automation scripting (if that's what people are still calling it!) but there might be a better solution I'm not aware of. Any suggestions?

• How to populate a private container for unit test?

  - by Sardathrion

  I have a class that defines a private (well, __container to be exact since it is python) container. I am using the information within said container as part of the logic of what the class does and have the ability to add/delete the elements of said container. For unit tests, I need to populate this container with some data. That date depends on the test done and thus putting it all in setUp() would be impractical and bloated -- plus it could add unwanted side effects. Since the data is private, I can only add things via the public interface of the object. This run codes that need not be run during a unit test and in some case is just a copy and paste from another test. Currently, I am mocking the whole container but somehow it does not feel that elegant a solution. Due to Python mocking frame work (mock), this requires the container to be public -- so I can use patch.dict(). I would rather keep that data private. What pattern can one use to still populate the containers without excising the public method so I have data to test with? Is there a way to do this with mock' patch.dict() that I missed?

• How to configure in crontab with condition statement for checks

  We like to monitor the NAS storage mounted on a linux box. We only like to be notified via mail when the usage exceeds a certain number say 80. We have only seen in linux books where most of them are calling shell scripts at certain times. How do we write inside crontab to only mail us if it exceeds 80 ? Usual eg 2 2 * * * /home/someUser/script.sh 2&1 | mail [email protected] Looking for solution like below 2 2 * * * if [ someNumber "80" ] ; then /home/someUser/script.sh | mail [email protected] Sincerely

• Stop Foxit PhantomPDF Standard from Opening PDFs in Internet Explorer 11

  - by pk.

  Is there a way to stop Foxit PhantomPDF from opening a linked PDF in the browser plugin? My desired behavior is for it to open the PDF in a Foxit PhantomPDF window. I've looked for an add-in, but there is none. Foxit support recommended the following solution -- select File Preferences File Associations Advanced Uncheck Include Browser... Select OK Select Make Default PDF Viewer but it didn't make a difference. How exactly is Internet Explorer making the decision to open it in the browser plugin instead of a separate PhantomPDF window? How can I change that?

• How to explain DRM cannot work?

  - by jerryjvl

  I am looking for the shortest comprehensive way to explain to people that are trying to use DRM as a technology to prevent users from using their data in some fashion deemed undesirable, why their solution cannot work by definition. Ideally I'd like something that: Covers why technically it is impossible to have people access local data, but only in such-and-such a way Imparts an understanding of why this is, to avoid follow-on "But what if" rebuttals Is intuitive enough and short enough that even a politician (j/k) could grasp it When faced with this situation I try to be clear and concise, but I usually end up failing at least on one of these points. I'd really like to have a 'stock' answer that I can use in the future.

• Why Windows Media Center (Vista 32-bit) unable to record TV Series?

  - by Alex R

  I can record individual shows just fine, but trying to setup the recording of a Series throws an error (something like, "unable to schedule, try restarting Media Center", pops up in the bottom right of the screen). Trying to access the "Other Showings" menu causes Media Center to crash ("check for a solution online" dialog comes up). The machine is a fresh reinstall of 32-bit Windows Vista from the HP recovery CDs, plus all Microsoft updates and service packs. Hardware: HP s3220n, AMD X2 5000+, 2GB RAM, 300GB free space on disk. Media Center came bundled. The "Media Center update for Vista" failed to install (it says, not appropriate for my computer). Any ideas? Thanks

• Redirect audio from laptop to desktop over LAN

  - by Ram Rachum

  I want to be able to play a song on my laptop and have it sound through my desktop's (infinitely better) speakers. If you're familiar with Input Director: I want something that is to audio what Input Director is to mouse/keyboard. I want something that automatically redirects all audio from the laptop to the desktop in real time, and I want that solution to require, like Input Director, minimum maintenance. Beyond the initial setup, I don't want to have to babysit the program that does this. I want something that launches automatically with Windows and just works, and also allows me to cancel it whenever I want. And also doesn't go crazy when the laptop is turned on in a different network where the desktop computer isn't available. Any suggestions for such a program? (I use Windows XP on both computers.)

• How to fix incorrect margins when printing from Windows 7?

  - by Rodrigo Guerreiro

  My printer is a HP Photosmart 2575. When I print from my Windows XP the margins are all ok, but when I print from my Windows 7 laptop the top margin is 2x larger for the same document, and as a result the bottom is cropped. I've already found one (http://h30434.www3.hp.com/t5/Printer-All-in-One-Software-and/Deskjet-5150-printer-incorrect-margins-with-Vista-64-bit/td-p/103166) thread in HP forums from someone that seems to have the same problem than me, but no solution is provided. My Windows 7 is the Home Premium x64. Can anyone help me?

• Automatic switching between monitor configurations

  - by Michael Aquilina

  I have a laptop and an external monitor and i was wondering if there was a simple approach to switching between multiple monitor configurations based on the detected available displays. For example: When i am at home and i plug in my external monitor i would like this to automatically become enabled and the laptop screen to become disabled. As soon as i pull out the display cable for the external monitor, i would like the laptop screen to automatically become enabled. I was expecting this to just "work" just like it does in windows - but it seems to be much harder than that. I am aware of the xrandr command to turn displays on and off but i cannot seem to find a way to get this to work the way i describe above. I had also found this post about switching between multiple monitor configurations and the results seem a bit inconclusive. However i was hoping that with xrandr there would be a simpler solution. For me, the fact that when i pull out my external monitor the screen just goes black and i get an error message is a big issue holding me back from making the complete switch to linux as i move around alot as a student. My OS of choice is currently Kubuntu 12.04 but i am willing to change to something else if it provides a better way of setting up the described setup.

• Oracle Virtual Desktop Infrastructure

  - by Fat Bloke

  A lot of the recent blog entries here have been about Oracle VM VirtualBox, possibly the coolest personal desktop virtualization product known to man. Deploying VirtualBox on your PC or Mac lets you run many virtual desktops at the same time to one user, you. But did you know that VirtualBox can also power an Enterprise-scale virtual desktop deployment too, delivering many desktops to many users?  As part of another Oracle product, Oracle Virtual Desktop Infrastructure (VDI), VirtualBox can run your Windows, Linux or Solaris desktops on servers located in the datacenter. Oracle VDI orchestrates the whole deal by looking after : creating or cloning the virtual desktops from a master template; managing the lifecycle of the desktops (create, start, suspend, resume, stop, delete); assigning which users get which desktops;  delivering easy and fast access to these virtual desktops from almost any device, such as existing PCs or Macs, iPads, or specially designed Sun Ray client devices too; load balancing and session management of all of this.  Architecturally the solution looks something like this: This is an increasingly hot area of the IT landscape, so the Fat Bloke has decided to create a new blog category (VDI) and dedicate a few blog entries to look into this in a bit more detail over the next few weeks. Watch this space... - FB
