• How to kill volume when headphones pulled out

  - by wonea

  I often use headphones in order to listen to music in work time. However my chair tends to occasionally have the tendency to yank the headphone cable from my laptop. Now with my Android phone this wouldn't be a problem as the music will automatically stop playing. However, Windows does not kill the volume and instead re-routes the sound to my laptop internal speaker system. Aside from turning off my laptop speakers - is there a small utility available which serves my purpose of killing the volume so my work associates aren't inflicted with erroneous musical tastes?

• Two Routers, Two Internet (1 Open, 1 PPTP) - Routing?

  - by SomeUser

  Hi there, I'm trying to setup two routers - one to route specific sites to a always-on PPTP VPN connection, the other for open internet access w/ firewall. First router is connected to Internet w/ built-in firewall. Second router is connected to a PPTP VPN connection. I was going to connect a wire between the routers and would like some insight on how to get both groups of systems (connected to each router) to talk between automatically. Even better would be to setup one gateway for certain sites and another for general Internet. The other option is to default all sites to the net and shoot others to the gateway or vice versa... Any insight so I can get a better grasp of this? Thanks!

• How to extract jpegs from a video file using ffmpeg

  - by Andrew Simpson

  I am using C# and ffmpeg. In this scenario I have 279 individual jpegs and i have used ffmpeg to create a AVI file from these images on my client. CMD Line: -f image2 -r 10 -i "C:\000EC902F17F\img%05d.jpg" -s 352x288 -y "C:\1\test.avi" I then upload to my server. CMD Line: -i c:\1\1.avi c:\1\img-%05d.jpg I then extract jpegs from the AVI file. I get 265 jpegs back. Obviously ffmpeg is dropping these frames (most probable) when the avi is 1st created. Is there a way to 'force' to encode using ALL the images I have? Thanks. PS I did not specify any command line option other than the size of the video output. As far as I am aware if none are specified then ffmpeg automatically chooses the best ones?

• How to forbid programs from accessing a folder

  - by prashanth

  I use firefox as my default browser. IE and chrome are used as secondary browsers. Apart from these, i need to have a alternate browser. I tried opera, but when installing it, opera automatically imported all my bookmarks and other profile data from firefox folder. I really had a hard time safely deleting these files that opera made a copy, without harming the original files which firefox uses. I don't want this to happen. Here's the situation: Now, i want to install other browser or re install opera. How do i make the firefox profile folder to be accessed only by firefox.exe and me(the administrator)? Can this be done via security tab under folder properties?

• Microsoft Outlook tips and tricks for improving user experience?

  - by Roee Adler

  I'm one of those heavy Microsoft Outlook users, currently working on the 2007 version. God knows this tool is heavy and may impose problems. I wondered what the Super User crowd has to suggest in order to improve the usage experience. Several suggestions of my own: Always work in cached mode (Tools--Account Settings--Change--Use Cached Exchange Mode) Use Outlook's local archiving capabilities Use Outlook's RSS reader - it's simple and allows offline access to your feeds If you have e-mail subscriptions to magazines, blogs, etc. - create a subdirectory to keep them, and a rule to automatically move them there when they arrive (one rule per subscription, based on the sender e-mail.) You can also share suggestions that require configuration of Exchange Server, for those of us who can make bring them to their IT managers. What are your suggestions? PS: "Use Gmail" is not an accepted answer, some of us don't control what email system we use...

• Securing a persistent reverse SSH connection for management

  - by bVector

  I am deploying demo Ubuntu 10.04 LTS servers in environments I do not control and would like to have an easy and secure way to administer these machines without having to have the destination firewall forward port 22 for SSH access. I've found a few guides to do this with reverse port (e.g. howtoforge reverse ssh tunneling guide) but I'm concerned with security of the stored ssh credentials required for the tunnel to be opened automatically. If the machine is compromised (primary concern is physical access to the machine is out of my control) how can I stop someone from using the stored credentials to poke around in the reverse ssh tunnel target machine? Is it possible to secure this setup, or would you suggest an alternate method?

• How can I copy the output from a remote command into the local clipboard?

  - by cwd

  I use iTerm2 as my terminal client in Mac OS X. On the local system I can use pbcopy and pbpaste to transfer data between the system clipboard and the terminal, but of course this doesn't work when you're ssh'ed to another machine. Is there some way which I can take the result of a command and copy it to the clipboard automatically? Perhaps an applescript to grab the text on the iTerm windows, then get the next to last line? For instance, if I wanted to copy the current working directory: I run pwd, then use the mouse to select the text, and then press command + c. Is there any better / faster / automatic way of doing this? I'm not looking for a bulletproof solution that would work for every command (eg: might not work when there is a huge scrollback) - I'm just looking for something to make this task that I do quite often a little less tedious. Update I'm looking into using screen to do this, but I'm still not sure if it is possible.

• Complete solution to upgrade PostgreSQL on debian production server

  - by Daimon

  I'm using Debian 6 (Squeeze) in production for a couple of websites. I decided to use postgresql backports so that I could use PostgreSQL 9.0 features. I thought that it would remain 9.0 and receive updates to that major version. Unfortunetly Squueze backports were updated to PostgreSQL 9.1 so probably I won't receive updates to 9.0. I'm planning upgrading to 9.1 but I know that it's not done automatically. I've read about official pg_upgrade and debian's pg_upgradecluster, but I would appreciate complete guide to upgrade. What are steps to do (first apt-get install postgresql, then pg_upgradecluster, then remove old cluster)? List of steps would be nice. What are possible failure scenarios? How to prepare to failures and react on them? I can stop database for a couple of hours only so I want to be prepared

• Why is Thunar not creating and showing thumbnails of images?

  - by darenw

  Thunar is my main file manager. Normally it automatically creates thumbnail images of all images in the directory being viewed. After experimenting with other Linux distros then installing Arch Linux once and for all, Thunar is not showing thumbs. Image files all get the same generic image icon. Googling turned up some information: Something called gvfs needs to be installed. I have it. Still no go. (Apparently this isn't actually needed anyway.) Someone had this problem and fixed it by running some mime-related command (I didn't save any notes) I did this same command but no go. Checking the obvious: in Thunar's Edit/Preferences, yes, the [x] Show thumbnails is turned on. When I view one image in GIMP or EOG, the generic icon in Thunar is replaced by a thumbnail. But only for that one file I opened.

• Auto-crop black margins dynamically of scanned images?

  - by naxa

  I have a notebook photocopied and the photocopy scanned, about 200 pages. For various reasons I need to print this material. There are large amounts of black areas at the sides of the page (after the page itself ends), "black margins". The image looks like this: I would like to remove the black places, but keeping all text. * The even and odd pages have the black part at different places. * Notably, there is a white edge outside the black one, too! * Most notably, the black areas has no fixed width (I've tried to overlay all the images for even and odd pages separately). It's width varies. The batch algorythm should be able to detect it. Is there a way to remove these black-white margins automatically, keeping the text?

• Scheduled task username changed

  - by Ernst

  I posted this originally on stack overflow where I was told I should ask it here: Hi, I created a user on our exchange server, but later changed the username. Now, when I create a scheduled task for that user, and change it's settings (run only when logged on), the username is automatically changed back to the old username. What's causing this and how do I make sure the correct, new username is used for the task (otherwise it won't run), security settings are okay. I did already log in with a different user to delete the profile on the computer and tried again with this user to no avail. The OS is windows xp, the exchange server is on windows server 2003. Thanks

• Free Markdown JS viewer

  - by maaartinus

  I'd like to use Markdown for documents to be exchanged with a colleague of mine. The ideal workflow would be IMHO editing the source in any plaintext editor while simultaneously viewing it in a browser. The client viewer should be able to redraw the text after each save automatically, and ideally even always switch to the most recent source file (so I don't need to navigate there manually). It'd be nice if I could (was allowed) modify the viewer a bit, things like using trailing spaces for line breaks are really terrible (I don't see them, my editor strips them, git complains about them, etc.). I'm interested in a software capable of this and easy to modify, and also in your opinions on the described workflow.

• What's the utility of the return command in autohotkey?

  - by Shashank Sawant

  In the instances where the return command returns a value, the utility is obvious. I have seen the return command being used even when it is seemingly unnecessary. Let me show the following examples: Example 1: Loop { if a_index > 25 break ; Terminate the loop if a_index < 20 continue ; Skip the below and start a new iteration MsgBox, a_index = %a_index% ; This will display only the numbers 20 through 25 } Example 2: IfWinExist, Untitled - Notepad { WinActivate ; Automatically uses the window found above. return } Why is the return command used in Example 2 but is not used in Example 1? Both examples are copy-pasted/modified-pasted from the autohotkey.com's documentation.

• Mac OS X app window is too large - how can I resize?

  - by Kyle Cronin

  I'm a MacBook user, and when I'm home I plug into a large external monitor to get additional screen space. When I'm on the go I disconnect and use my laptop's built-in display. For the most part this arrangement works very well; however, I occasionally run into an issue where I'll resize an app on the external, causing it to be too large to fit on the built-in screen when I disconnect. Most apps don't have a problem decreasing their height automatically or resizing to fit when I click the green orb, but some (like iTunes) don't want to cooperate. How can I resize apps like iTunes without reconnecting to my external? Here's a screenshot:

• How to tell httpd to preserve the proxied error message?

  - by ZNK - M

  I have an httpd server proxying the requests to 2 different tomcat servers. One of my server handles the authentication and returns a specific http error code 521 when the user already have a running session. My issue is httpd automatically maps this 521 error code to a 500 (internal server error) and then my client can not handle it properly. I have tried to disable ProxyErrorOverride, to remove the /error/HTTP_INTERNAL_SERVER_ERROR.html.var but it does not changes anything. How can I ask httpd to not change anything to the proxied message? <IfModule proxy_module> ProxyPass /context1 http://127.0.0.1:8001/context1 ProxyPass /context2 http://127.0.0.1:8002/context2 ProxyPreserveHost Off ProxyErrorOverride Off </IfModule> Thanks in advance httpd 2.2.22 (Win32) mod_ssl tomcat 7.25 windows 7 64-bits

• Is there anyway to stop Windows 8 from restarting for an update?

  - by William Hilsum

  My Windows 8 machine is going to restart shortly... I have tried a few techniques such as shutdown /a which is not having much luck. Short of pausing the Windows Update service, is there anyway to stop this restart from happening? ---update--- Looks like the "restart" is all talk and no action! The time has gone and I am presented with this: So, it goes along with the top answer here (which I shall shortly accept) --- update again--- It did reset!!! My battery went critical and it turned itself off, I turned it back on (out of suspend) when it was plugged in, I logged in and the first thing it did was automatically restart - closing my open tabs in Chrome :( Oh well...

• Browsing not working in Windows 8

  - by Jonathan Perry

  I'm using Windows 8 Professional installed on Windows 7 using the "Save my preferences and apps" installation option. The Windows works great, apps are downloading and I can listen to online radio stations using the TuneIn radio app meaning the internet connection is alive, however, when I open a browser (either Chrome or IE10) and try to browse the internet, I'm getting an "Unable to resolve DNS" error message. Prior to installing the internet browsing worked flawlessly I must say. I'm using ESET NOD32 Antivirus so I suspect that it might interfere with the web connection now, but I'm not so sure. Internet options show that the PC is set to resolve the DNS automatically. I don't know what to do. My other Win7 PCs in my wifi home network are connecting to the internet without any issues. If anyone can help me resolve this I'll be grateful :) Thanks

• Domain name is forwarding to my localhost, no idea why

  - by Dustin Fineout

  On my local development machine, I have a WAMP setup (Windows Vista Home Premium, Apache 2, MySQL and PHP 5). One of my projects is rehash.dustinfineout.com, which may be related to the problem... For some reason, when I try to visit http://www.rehash.com in a browser, it forwards automatically to 127.0.0.1 loopback/localhost. I discovered this entirely accidentally. I have already looked at the http.conf and extra/httpd-vhosts.conf Apache configuration files and these are not causing it. I also checked the windows hosts file but that had no entries in it either (C:/WINDOWS/System32/drivers/etc/hosts - maybe there is another location I need to check). Any ideas? Just to clarify, rehash.com is NOT my domain.

• Can I recover a lost text file in Windows 7?

  - by Marcus Johnson

  How can I recover a lost text file in Windows 7?? It has very important information in it and of course, it is gone because of the stupid Windows Update thing....it just automatically closed all of my stuff and restarted my computer!! Would the text file possibly be in the Temp folder in my computer?? I don't know much about this stuff...but I need it. I didn't save the file which makes me think I can never get it back...but I want to make sure. Thanks. I was using notepad.

• Options for remote desktop software for helping remote users?

  - by Nick G

  I need an easy way to jump on someone elses machine to help them solve a problem. It needs to be really easy for them to install (preferably doesn't actually require an "install" but just running an exe?). It must punch through any firewalls automatically using a relay server or P2P (so Remote Desktop itself is no use to me). I've found commercial products like MeetMeNow but they're really expensive. I want something that you can either buy a cheap pack of sessions or minutes, or preferably something free. I'm not in the business of commerical support and would only use it once every couple of months perhaps.

  - by Arthur

  Hi everyone, i hope someone can help me with this problem. I have a Dell vostro 1310 Laptop with 32 bit vista and a 8400M nVidia chip. Recently i have noticed performance issues when my girlfriend was playing Sims 3, and then one day i turned it on and all i got was a thick white line at the bottom of the screen. i heard the OS start up so automatically i thought it was a damaged screen, but i had doubts so i plugged it into an external display via the vga port. it worked but everything appart worm the OS choice menu looks distorted beyond belief. even the bios screen had multicoloured lines running down the screen. The resolution is non existant, the screen only shows a 256 colour pallette and is heavily distorted. i barely managed to get to the device manager where i found the gfx card with an exclamation mark. does anybody have suggestions? should i buy a new mobo or are repairs possible? thanks in advance

• Re-configuring mysql-server 5.1

  - by sitonico

  Hi all! Some days ago I had some problems with updates, and this ended up with a problem that I already solved in this question . The problem is that now I want to update again, but it seems that I cannot do it automatically, because when I use the update manager it gets stuck while configuring mysql-server 5.1, in the line : Configuring mysql-server 5.1 (5.1.41-3ubuntu12.10)... I have been looking for some solution but it seems hard because actually I don't know where to start, so any hints are appreciated. Thanks in advance! Alf.

• Internet Explorer 8 Viewing PDF files vs saving them

  - by Andy Evans

  I have a user asking about viewing PDF files in Internet Explorer. When she clicks the file link on a website, IE prompts her to save the file, which she then has to open to read. What she's not seeing in the prompt is the ability to open the file without having to save it, or, just opening the PDF automatically. She and a few others are having the same problem, while a majority of the user do not have this problem. All of the users have IE 8 and Adobe Reader 9 installed. I've verified that Adobe Reader's "Display PDF in browser" option is enabled. What else should I check?

• How can I keep websites from knowing where I live?

  - by D Connors

  This questions is related to issues and practicality, not security. I live in Brazil and, apparently, every single website I visit knows about it. Usually that's ok, but there are quite a few sites that don't make use of that information adequately. For instance: Bing keeps thinking that brazilian pages are way more relevant to me than american ones (which they're not). Google.com always redirects me to google.com.br. Microsoft automatically sends me to horribly translated support pages in portuguese (which would just be easier to read in english). These are just a few examples. Usually it's stuff I can live with (or work around), but some of them are just plain irritating. I have geolocation disabled in firefox, so I guess they're either getting this information from my IP or from windows itself (which I bought here). Is there a way to avoid this? Either tell them nothing or make them think I live somewhere else? Thanks
