• Edit write-protected files by breaking hard links

  - by Taymon

  A directory which I own and can write to contains hard links to files that I don't own and don't have write permission for. I want to open and edit these files in Emacs. When I save my changes, Emacs should rename the existing hard link by appending ~, then write my new version of the file as a new file owned by me. I was under the impression that Emacs could just do this (because of the way it does backups), but it's not working; when I save, it attempts to change the file's permissions in order to write to it (and fails because I don't own the file). How do I make this happen?

• How do I resolve the error "Excel found unreadable content in (filename)"?

  - by Vernon

  Has anyone else seen this? Sometimes when I open certain worksheets in Excel 2010 I see the message in the title. Excel then asks if I want to repair the file. I say "Yes" and Excel reports that the file is repaired. A log file says something about removed records. However, there does not seem to be anything missing from the file, and all sheets and VB macros in the workbook work just fine. Any suggestions?

• How can I send SMS from my PC using my Android Phone (Galaxy S3)

  - by Dean Rather

  I've been a long-time Nokia fan, but finally succumbed to the Samsung Galaxy S3's amazing screen, & Android's Open community. One feature I use a lot (about a hundred times a day...) is Nokia PC Suite's ability to send SMS via the phone. It: Uses my phone's contact list. Notifies me when I get an sms. Allows me to send SMS using my PC's keyboard. Essentially turning SMS into just another IM medium I use on the PC. How will I do this with the Samsung Galaxy S3 + Windows 7?

• How can I fix a computer that is infested with malware and is extremely unresponsive? [closed]

  - by fredley

  Possible Duplicate: How do I get rid of malicious spyware, malware, viruses or rootkits from my PC? I'm troubleshooting a Windows 7 PC for a friend. A couple of days ago it started running 'slow'. It turns out 'slow' is about 15 minutes to the first glimpse of the desktop, and another 30 to show icons. It is possible to open Task Manager, and nothing seems awry, CPU usage at 1-5%, plenty of memory free. The machine is clearly infested with malware though, in particular a program called 'Optimizer Pro' is demanding money to 'remove 5102 files slowing down my computer'. This seems highly suspicious. My problem is though, that I can't access msconfig (I left it for a couple of hours after having hopefully typed it into the Start Menu and hit enter - nothing seems to have loaded), or anything at all basically. I can boot from a Linux Live CD, but can I actually do anything useful from there? System Restore hasn't fixed it either, and Safe Mode exhibits the same behavior.

• Is it possible to stream music/video from an Apache server?

  - by rphello101

  I'm just starting to get into setting up a server. I've set up a basic Apache server to access some songs and movies. When I click one of the songs though, nothing happens. When I click one of the movies, sometimes it will open a new web page and act as though it is going to start playing, but never does. I know Apache is HTTP, not FTP and read somewhere that that could be a problem, but I'm uncertain of the differences. Anyway, is it possible to click on one of the songs and have it start streaming using, for example, Windows Media Player? If so, might someone either explain how to do so or direct me to where I can find it? Any information on retrieving media from an Apache server at this point would be most appreciated. -Edit- I don't know if it matters, but I'm using Windows 7 and Google Chrome

• Error when starting Outlook 2007 on Windows 7

  - by Jared

  Every time I start Outlook 2007 SP2 on my Windows 7 box Outlook will look like its loading fine, then I get this error message: cannot start microsoft office outlook. cannot open the outlook window and outlook will close. I was able to get outlook to start by using outlook.exe /resetnavpane in the Start-Search box, a nice tip which I got from this social.microsoft.com page. But it didn't fix the problem since outlook is still complaining when it starts after a reboot. What can I do to get outlook to startup normally?

• How can WiFi access points recognize me?

  - by stephanos

  Due to heavy snowfall I was recently stranded on an airport. Having to do some surfing on my laptop I found an open access point. It offered 30 minutes of free surfing a day. I registered and used up my time. Then I wanted to see if I could use it again - mostly just for the fun of it. I opened a different browser then before and tried to register again. It didn't work. The access point recognized me and told me that I'd have to wait another day to get 30 free minutes again. I reconnected again to force a new IP - still the same. How did it recognize me?

• connecting hostname to server

  - by Michael Ropy

  I have an ubuntu server installed on my server with virtualmin webmin. everything is good the server itself....I can connect to localhost and the virtualmin manager (http://localhost:10000). the problem is, I can't connect to it from a client computer. For example when I enter the IP address of the server, its shows me 403 forbidden error (sometimes its shows the homepage right)...but the virtualmin manager could not open... if my website is example.com with this ip: xxx.xxx.xxx.xxx, i can't connect to example.com:10000 or xxx.xxx.xxx.xxx:10000 what should I do?

• How to Transpose in Excel a column with more than 50,000 rows?

  - by ezlee69

  I am trying to Transpose all of column "B", but want to skip a line then grab the next 4 and paste them in the same column. How can I make this loop all of column "B" skipping every 5th line and change the range to the next open cell or "Range" automatically without manually typing each one individually? Range("B12:B16").Select Selection.Copy Sheets("Sheet2").Select Range("A2").Select Selection.PasteSpecial Paste:=xlPasteAll, Operation:=xlNone, SkipBlanks:= _ False, Transpose:=True Range("B18:B22").Select Selection.Copy Sheets("Sheet2").Select Range("A3").Select Selection.PasteSpecial Paste:=xlPasteAll, Operation:=xlNone, SkipBlanks:= _ False, Transpose:=True Range("B24:B28").Select Selection.Copy Sheets("Sheet2").Select Range("A4").Select Selection.PasteSpecial Paste:=xlPasteAll, Operation:=xlNone, SkipBlanks:= _ False, Transpose:=True

• Customising error bars

  - by itid

  Hello I've been told I HAVE TO have custom error bars for an assignment I have to hand in. Okay, I have a scatter graph with twelve points, and the error for each one is different. It's the same plus and minus, but different for each one. The twelve different error values are sitting nicely in a column. I have been told I can reference that column in "custom error bars" simply by indicating the range of values, like F2-F14. However, I get an error message every time. When I open Custom Error Bars, it is set up like this: ={} obviously waiting for a function. The error message says remove the equals sign. How should I enter the value range, please ?

• Is there an intuitive way to reopen Empathy's contact list?

  - by aef

  Since a short while I'm using Ubuntu Oneiric Ocelot (11.10) with gnome-shell (Gnome 3) and I'm trying to get accustomed to the default Empathy Instant Messaging client. When I hit the close button of Empathy's contact list the window disappears as expected. When I now start Empathy over the Gnome Activities menu the contact list reappears. That's not as easy as clicking a system tray icon back in Psi on Gnome 2 but it works for now. But when I start a conversation first and have an open conversation window, then close the contact list, and try to regain access to it by using Gnome Activities, I only get the conversation window into focus and no contact list appears. I only seem to be able to get the contact list back if I close the conversation window (and thereby signal the conversations to be over) and then use Gnome Activities again to get my contact list back. That's horrible. Is this intended? Is there something I'm missing?

• Write but not delete

  - by hunix

  Hi, We are using glusterfs for our cloud storage needs. Since the partition is open to many servers, we would like to disable file deletion as we don't delete or overwrite any file. Glusterfs does not have ACL, so I need to implement this solution outside of the glusterfs. Perhaps I can mount the disks read and write only (with disabling deletion), but could not find any solution. Setfacl etc. does not work on the partition. How can we disable file deletion -at least- on the client machines? Thanks,

• Proxy server modifying request/response upon pass through

  - by jamiei

  I would like to set up a non-transparent proxy server that will selectively modify HTTP requests and responses as it passes them through. The motivation for wanting to modify the data on the fly and not at the original source are not part of the question. I'm hoping there is a solution which allows the modification scripts to be written in a mainstream programming language. I am aware of guides for Squid which allow you to flip images etc on the way through but I was hoping for a slightly more established and less hackish solution. Does anyone know of an established open source project or environment (Any major platform) which would allow me to script in arbitrary modifications to the data being passed through?

• Centos 6.2, Apache 2 and Listen port for socket connection

  - by salvosav

  I'm trying to make a socket connection between a client and my server through a php script. To do this, I opened a port on iptables, and configure a virtual host with apache to redirect all traffic from my door to the folder that contains the file index.php, which is my script. Doing some tests the door is open, but using command netstat -ltn , I see ':::35100'. Looking on the net I understand if in this way is only listen inward and not outward. But I don't understand how can I turn this ':::35100 '-' in this '0.0.0.0:35100 '. Or, better yet, how to add this rule. Any ideas? thanks

• Is there a way to expose ports when the three default firewalls were disabled

  - by Nactus

  I think I disabled the three firewalls that come with FreeBSD (just for experimentation purposes). I checked the modules that load with the kernel (using "kldstat"). The only modules that load are: kernel -- ng_socket.ko, netgraph.ko, ng_mppc.ko and rc4.ko). I'd like to know what module is still blocking my ports now. After removing all firewall options from the rc.file and re-compiling the kernel without the pf option (or any firewall for that matter), I can't still open ports freely. How does it work exactly? Thanks.

• Windows 8 won't load as it has to

  - by MichaelHefner

  I have successfully installed Windows 8 about eight months ago, and all went well. Only the last change I made ??is to set Startmenu8, to get a more normal for the Windows look. Yesterday, my computer screen went dark blue and the mouse does not seem to work. I changed the battery and reboot. But all I get is my desktop, taskbar, and not ikony.Programmy not appear at the bottom, but do not open the maximum so I can not use them. I have a Dell desktop and run the diagnostics on the F12 at startup. All right in line with this. I want to return to the previous item, but can not get in Windows, to do it. Any suggestions gratefully received.

• How to "get" a reliable parallel port on a laptop without a PCMCIA slot?

  - by ldigas

  Usb-Parallel port (for an old, but reliable matrix printer that has its special use) connections (cables) are unreliable. They sometimes work, sometimes don't - and since I installed Windows 7 I can't get neither of my old ones to work properly. PCMCIA is usually considered (and it is) a much more reliable solution, but unfortunatelly, none of my new laptops has a PCMCIA slot. So, all ideas are welcomed. What should I do? I'm open to all suggestions as long as you have some experience that they work more reliably than USB-Parallel cables and their wicked drivers.

• Prevent applications from being run as administrator

  - by Unsigned

  Background Most installation toolkits have the ability to launch, automatically or otherwise, external programs after installation. This is often appears in the installer via such options as "Show readme", or "Start program". Issue The problem is, many of these installers are poorly coded, and do not drop permissions appropriately, for example, opening the application's homepage in the browser... launching the browser with the installer's Administrative privileges, or a "High" UAC integrity level. This has the potential to open up security breaches, by opening up a webpage (and possibly browser addons), that are now running with elevated permissions. Question The question is: Is there a way to prevent certain applications (such as a web browser) from ever being launched with Administrative privileges, i.e., an automatic drop-privilege?

• How to block a website completely?

  - by user37076

  I want to block some sites(e.g. youtube,news sites ), because I have a problem with procrastination and I find these websites affect my productivity very much. I used to block them by adding them to HOSTS file. However, gradually every time I want to take a break, I open the hosts file and comment my block again. Is there any way I can block the websites and cannot (at least a little bit hard, e.g. I have to reboot my pc) unblock them. I have no access to the router or any firewall, besides the ones on my computer. I just want to FORCE myself to work without any chance to procrastinate.

• Seemingly random disconnections on Windows Server 2008 R2

  - by bobblez

  So I have a box running a Windows Server 2008 R2 in my LAN, which is running, among other things, a voip server used by other people. I myself am in the same subnet with the server, while the other users are not. Now, maybe on average twice a day, all the other users get disconnected from the server (and if I take a remote desktop connection to it, I'm not able to open any web pages either). These disconnections usually last only about 5 seconds, but sometimes they may last up to a minute. What could possibly cause this? I have all the updates installed from windows update and the motherboard of the server is asus p5b deluxe (if that is of any interest). edit: Forgot to mention that my own internet connectivity stays intact while the server's does not, and both computers are behind the same router.

• What alternative is there to Nginx that supports http keep-alive between backends ?

  - by felace

  Hi. I recently asked a question about how to keep a backend connection persistent using Nginx, but found out it wasn't possible anyway, It is an HTTP/1.0 proxy without the ability for keep-alive requests yet. (As a result, backend connections are created and destroyed on every request.) It works all fine right now (since the connection between client and Nginx is kept alive and the result is simply the same), but I don't want to establish a new connection every single time a new request is received ,even if it's on a unix domain socket. So, what software (preferably open-source and not too tedious to configure) do you recommend to accomplish that such connections ?
