• Ways to increase my Ubuntu partition space

  - by Andreas Grech

  I am currently running Ubuntu and Windows 7 as dual-boot on a single HD. The problem is that when I installed Ubuntu, I didn't allocate as much space as I thought I would need and now I need 'reinstall' Ubuntu so that I can increase the amount of storage space. Now there are two ways to go about this. Either I use use gparted to increase my partition space (but I read that it's not really that safe as regards data loss) or create the new partition with more space and reinstall Ubuntu there. But if want to reinstall Ubuntu, is there a way I can somehow "save" my current Ubuntu and install that one? What I mean is that I don't want to lose my current installed packages and files that I have on this partition. Is there a way to kind of maybe 'streamline' my current Ubuntu so that I install this one on the new partition? If not, what are your opinions as regards gparted?

• How do i get Safari to ignore the SSL Certificate error?

  - by Tangopop

  In IE 6, 7, 8 and Firefox 3.6.3 and 3.0.5 i have installed a local SSL Certificate on the machine i am testing on and i have gotten the browser to igonre the SSL error (which is off one of my Web Test servers) Now i am tryin to do the same thing within safari 4 and with no luck. Basically i am running some automated scripts to test my website before they go live and i need to be able to ignore these errors as they will all run autonomosly. This is the error screen i am trying to avoid: http://library.bowdoin.edu/news/images/ezproxy-err/safari.jpg As i say i have installed the certificate locally and the IE 7 browser on the same machine works fine.

• Which Wine DLLs should I *not* overwrite with the real thing?

  - by endolith

  I have a legit installation of Windows XP and dual boot with Ubuntu (currently Karmic). WineHQ says it's possible to use DLLs from a real installation of Windows in place of "DLLs that Wine does not currently implement very well". So I'd like to just create softlinks that point to all of the DLLs in my real Windows System32 folder, under the theory that this would help things function better and behave in a less buggy, more native way. But should I go as far as replacing the Wine DLLs with the real ones? If so, are there any DLLs that need to remain the way they are for compatibility with the Linux world? Which ones are safe to replace?

• Unable to open up port 80 on EC2 using elasticfox

  - by uswaretech

  I have launched an instance of EC2. Initially the security group I created did not have the port 80 open. I sshed and installed Apache etc, and now want to open port 80. I am using elasticfox. So I go to Security Group - [My Group name] - Grant new permission Open up the port 80(Http with TCP) for network range 0.0.0.0/0 Now my assumption is that these ports should be opened up on the instance, but the instance is not responding on the allocated IPs, public DNS entry. What should I do next?

• What kind of SSL Cert do I need and where do I get it?

  - by chacham15

  I want to have subdomains with SSL within my domain. The main difference is that each subdomain is hosted by a different person with a different public key/private key pair. Let me illustrate with an example: User send his public key and requests subdomain from foo.com User is added and assigned subdomain bar (bar.foo.com). Users public key is stored for future validation against bar.foo.com User goes to bar.foo.com and see's a validated SSL connection. From what I gather, this means that I need to create a CA, which is fine. The problem is that from what I recall, a CA needs a special sort of SSL Cert. How do I go about getting this?

• Exclude path from Windows 7 search?

  - by Jez

  It's really quite incredible how bad Windows 7's search seems to be. The latest problem I have with it is that I want to search for filenames including the string "user", so I go to the directory I want to search in (C:\Users\jez\testing), type *user* in the search box, and hit enter. It gives me... every single file. Because "user" is in the path of every file, with everything being under "C:\Users..." OK, this is useless. Is there a way to just search for the string within files rather than their paths, or do I need to download some decent 3rd party search software?

• Hard Drive Fundamentals And Verifying Disk Performance

  - by Agnel Kurian

  Over the past few months, my Windows XP machine has slowed down to a crawl. It takes about 10-15 minutes to go from power-up to reaching a responsive state. I have reasons to believe that this is a result of the hard disk slowing down. Questions: Do hard disks slow down as a result of mechanical wear and tear ...or age? How do I check if my disk has slowed down? Conversely, how can I verify that my disk is indeed running at the speed it's designed to run at? Could drivers be at fault here? Do hard disks come with drivers or does Windows use a generic driver?

• How to play from mic to speakers in Ubuntu Karmic?

  - by vava

  Ok, I have a silly problem. I have few bluetooth headsets lying around and I want to make DYI baby monitor out of them. All I need is for some application to listen to the mic and send it to the speakers. Loopback (even though it doesn't work) is not good enough, it'll send sound from the mic to the speakers in the same device but I need it to go across devices. So does anyone know some application that can do that? I'm looking for something small and easy to use, not jackd or similar.

• Using JCal Pro and Community Builder together for registration

  - by Kate

  Does anyone know if there is a way to use JCal Pro and Community Builder together in order to have users register for a specific event? When our new website was designed JCal Pro was implemented with the idea that individuals could look at the calendar and see what events they wanted to sign up for based spots open for that specific day. Now that we have more events and scheduling has become a major issue. For another project we installed CB in order to allow individuals to register and create profiles for an annual event. As I am looking at this nightmare I am living trying to organize various groupings of people I am assuming that there has to be some sort of a way to connect the two up so that those who have a user account through CB could also go in look at the calendar and sign up for an event. There is a JCal plug-in installed in CB however I have not had much luck at figuring out its functionality. I am running: Joomla 1.5.14 JCal Pro version 2.2.7.441 Community Builder: 1.2

• What do you do when you need whole-words search in Firefox?

  - by romkyns

  Example: I am looking to see if "arg" is a special keyword in Lua. I go to the Lua reference manual at http://www.lua.org/manual/5.1/manual.html. I search for "arg". I find hundreds of occurrences of the word "argument(s)" or "vararg". Any ideas? I know Firefox won't implement whole words as a core feature (something about cluttering up the ui... argh...), and I couldn't find a good addon that implemented this well.

• Issues with MongoDB install on Ubuntu 8.04 LTS

  - by Tom

  I am installing MongoDB (1.4.1) on Ubuntu (8.04 LTS) and I continuously have a problem where I can be in /usr/local/mongodb/bin and run ./mongo or ./mongod and I am returned "No such file or directory." Let me be very clear here... the files ARE there! The obvious go-to solution is that it is because of permission issues but the permissions are fine. I've even tried others out, still without any luck. I'm really at the end here and any help would be MUCH appreciated. Thank you!

• View unknown content-types in Firefox?

  - by dirtside

  A certain URL on my server returns Content-Type: application/json. The filename ends with .phtml, so whenever I go to it, Firefox 3.5 asks me if I want to save it or open it with another program. But the answer is neither; I want to view it in Firefox as if it was text/plain. Suggestions? The Applications tab of the Preferences window doesn't give this as an option for the "PHTML" type which now is listed in there (ever since I tried to open it with no external program).

• Alternative to the tee command whitout STDOUT

  - by aef

  I'm using | sudo tee FILENAME to be able to write or append to a file for which superuser permissions are required quite often. Although I understand why it is helpful in some situation, that tee also sends its input to STDOUT again, I never ever actually used that part of tee for anything useful. In most situations, this feature only causes my screen to be filled with unwanted jitter, if I don't go the extra step and manually silence it with tee 1> /dev/null. My question: Is there is a command arround, which does exactly the same thing as tee, but does by default not output anything to STDOUT?

• Can I remove the ctrl-z key binding in my shell?

  - by Nagel

  The background for this question: I currently have to do a lot of my work in terminal over ssh, and I use screen quite a bit. Because I found the ctrl-a key binding for screen commands so annoying since I'm accustomed to using ctrl-a to go to the beginning of a line, I changed it to ctrl-z. The only problem with this is that when I'm in Matlab, think I am in Screen but am not, pressing ctrl-z will instantly kill my Matlab session, because ctrl-z is the key binding for suspending processes in *nix. So the question is: can I remove the key binding for ctrl-z in my shell so that it does no longer suspend a process? My shell is terminal.app on OSX.

• Missing Right Click Menu Text After Sleep

  - by petebob796

  I have a laptop running Windows 7 and regularly close the lid to put it in sleep mode. Recently after resuming from sleep if I go to access the right click menu in the windows shell when I hover over the menu items the text disappears and doesn't re-appear without closing the menu and right clicking again. The only way to fix this is to restart. Any ideas what could be causing this? I have an nvidia 8600m gs graphics card which had a BSOD problem a while back at boot up but since I underclocked it slightly it has been running fine and I experience no other issues but this. This only affects right click menus that are part of the windows so not any programs right click menu. It's not a major problem just strange and a little annoying.

• nginx rewrite rule for using domain host to redirect to specific internal directory

  - by user85836

  I'm new to Nginx rewrites and looking for help in getting a working and minimal rewrite code. We would like to use urls like 'somecity.domain.com' on campaign materials and have the result go to city-specific content within the 'www' site. So, here are use cases, if the customer enters: www.domain.com (stays) www.domain.com domain.com (goes to) www.domain.com www.domain.com/someuri (stays the same) somecity.domain.com (no uri, goes to) www.domain.com/somecity/prelaunch somecity.domain.com/landing (goes to) www.domain.com/somecity/prelaunch somecity.domain.com/anyotheruri (goes to) www.domain.com/anyotheruri Here's what I've come up with so far, and it partially works. What I can't understand is how to check if there is no path/uri after the host, and I'm guessing there is probably a way better way to do this. if ($host ~* ^(.*?)\.domain\.com) { set $city $1;} if ($city ~* www) { break; } if ($city !~* www) { rewrite ^/landing http://www.domain.com/$city/prelaunch/$args permanent; rewrite (.*) http://www.domain.com$uri$args permanent; }

• Mapping skydrive as network drive in macos

  - by vittore

  as you probably know, if you have windows live account you can use free skydrive 25 gb storage. Even more a lot of people know that if you go to your skydrive in browser and copy cid query parameter value (https://...live.com/...&cid=xxxxxxxx ) you will be able to map skydrive as network drive in windows using this network pass \[cid].docs.live.net[cid]\ I do now that if you have network share like \server\folder i can map it in macos too, as smb://server/folder. however it is doesn't seem to be a case with skydrive when i try to map it as smb://[cid].docs.live.net/[cid] finder tells it can't connect. Anyone know how to map it ?

• Lightweight, low cost enterprise backup solution

  - by Scott

  Looking for a backup solution primarily for Windows clients (XP/7), that will either back up to 2 different servers (1 on site, 1 off site - internet - can be our own server), or back up to 1 server and then we would need to somehow backup that server offsite/internet. By lightweight, I mean the backup client software should not eat up much memory and processor since some of the client machines are older. I am used to using Crashplan for home use - the pricing is nice for the amount of backup I get, and it works great / easy to install and get going - I can back up to my own machines locally and over the net. However, the price is going to be a little steep for enterprise level backup, 1500+ machines. Possibly ZManda and Bacula are good choices to consider? Are they light weight? Can the clients/agents be set to go over the net and/or multiple backup servers?

How do I get this to work. Thanks.

• How Will Mac OS X Snow Leopard Upgrade Work?

  - by Blaenk

  I am relatively new to Mac OS X. I got my MacBook in January, and I have never experienced a new version of the operating system. I am wondering if I should simply upgrade my install to Snow Leopard. I come from Windows where it is advised to do a complete reformat. I would rather not do this, however, and I have a feeling that due to Mac OS X' POSIX based nature, it might actually not be all that bad if I upgrade. I guess if things end up screwing up I can simply go ahead and reformat, but I am wondering what it is like to upgrade systems running Mac OS X. I wouldn't want my Snow Leopard installation to be somehow deficient due to certain inconsistencies within the system.

• Restarted computer, now wireless and Visual Studio is broken

  - by Earlz

  I installed the new update for TortoiseSVN which requires a restart. Upon restarting a lot of things broke. I'm currently running a virus scan, but what would cause this? Among the things that no longer work is Visual Studio. It now says "Invalid License Data. A reinstall is required" and my wireless internet does not work. When I go to connect to my network it will say "Can not connect" and then when I diagnose the problem it says "The connection to accesspoint-name was cancelled" (and yes, canceled is misspelt like that) What could have caused this? My computer did not install any updates or anything like that upon restarting and it was running fine before I restarted it.

• How to disable a McAfee service?

  - by AngryHacker

  I am trying to disable a McAfee Real-Time Protection service, but if I go into Services/Properties, then try to set it to Manual or Disable - it says that unable to open service McShield for writing on Local Computer. Error 5. Access is denied. I've tried logging in as an Admin, to no avail. I've tried resetting permissions in the registry to the key where the McAfee service is described...nothing helped. Logging in with Safe Mode did not help either. How can I disable this service? Is there a way to disable a service before even getting into Windows? P.S. Uninstalling McAfee is not an option.

• "ssh_exchange_identification: Connection closed by remote host lost connection" when running cron job

  - by grautur

  I have a Ruby script that connects to a remote machine via ssh and executes a command. The script runs fine when I just run it in my terminal. In my crontab, I have 1 * * * * /bin/bash -l -c 'ruby myfile.rb' and if I go ahead and run /bin/bash -l -c 'ruby myfile.rb', everything executes fine. But when cron itself executes the job, I get a ssh_exchange_identification: Connection closed by remote host error. What's the cause of this? How do I fix it?
