• equivalent to CDN but for dynamical content?

  - by ajsie

  so i know for serving static elements (css, js, images, videos etc) you should use CDN since they are spread out throughout the world. but how could i spread out by apache servers? is there an equivalent to CDN but for dynamical pages? or is it the traditional LAMP way. if so, i guess my best option is to find an international hosting provider that hosts in different countries, so the content will be served from the country located nearest the client machine. any suggestions of such hosting providers? or is it best practice to contact different hosting providers in different countries that do not relate to each other. what is the right way to go?

• Delete Ubuntu and Grub from PC (and BIOS unaccessible)

  - by Temitope

  I've really done a mess while upgrading 12.04 to 12.10, or my PC did, or ubuntu did, I can't really tell. The situation now is I have a dual booting machine, Windows 7 and ubuntu 12.10 -When turning on the PC, I can't access boot options, I've tried every thing, esc, f1 f8, f10 (I have a Hp pavilion) but all I can see is a short-lasting screen with three lines reading something like "error:files not found" or "link not found". So the PC turns to the Grub loader screen. This is already a BIG problem. It means I can't change boot order, and I'm diperate, since it doensn't seem that repairing my operating systems will bring my BIOS back. -If I chose Ubuntu in grup, it loades but then frezes on the desktop, I may be having problem with unity3d, or compiz, which was reported to be crashing the first times I started ubuntu. Now, after turning off and on the pc several times, no crash is reported again. Ubuntu just load my background image and nothing else. Not the side menu, not the header, nothing. Althogh the system seems "functioning", when I press the power button on the PC, for example, the normal shutdown dialog window appears. -If I chose Windows, Grubs tells me that something is not found, and to press any key to continue; I do it and then Windows loads perfectly. What I now want to do is 1- use EasyBSD to change boot order and boot Windows partition first 2- delete the ubuntu partitions from within windows disk manager What I except happening is that My PC turns to, or near to factory booting settings: I press the power button and Windows loads without asking me nothing I have acess to all my hardisk from withing windows Is that what will really happen? Are there danger I'm not seeing? What I don't except happening is The BIOS access key return functioning How could I eventually solve this? I would like to reinstall Ubuntu, 32 bit version this time.

• Which UPS, for home use, which can automatically shutdown the PC when battery is low?

  - by Tony_Henrich

  I am planning to build a single server machine which is highly dependent on data residing in RAM for performance reasons. I am looking for a UPS which can power the PC during a blackout (very rare) and when the battery level is like %20, it sends a signal to Windows 2008 to shutdown. Even if it's only for a few minutes, that's good enough. This is for home use so I am looking for an inexpensive unit ( less than $300? ). Which brand/model is good choice? I prefer one whose battery is easily & cheaply replaced.

• cant access my local web server with the external IP

  - by TommyG

  I havent been able to find a solution to my particular problem. I have a MAC which I set up as a web server and configured my router to forward to the local IP. When trying to access my site from outside, it does say "It works!", however, when I call a simple Hello World PHP script that I have, I am getting an error that the page could not be opened. I did enable PHP on my machine so thats not the problem. I really have no idea how can I access - I followed so many tutorials and did everything correctly. My router is a Linksys WRT160N if it matters at all. In the port forwarding section, I selected to forward

• How to access network shares, printers, etc.through Windows 7 Built-In VPN?

  - by mbrion

  After I have successfully connected to a Windows 7 box via the built-in VPN: how do I access shares, shared printers, network appliances, etc.? So, call me bad at googling, but: I can find dozens of articles on "How to Set up a VPN Connection" and "How to connect to a VPN" for Windows 7... but I can't find a single article on how to access resources after connecting. I have a home VPN set up in Windows 7; I was able to connect to it from my friend's Windows 7 machine last night. I expected to be able to UNC into my shares; I also expected to be able to go to "Start Computer" and Click "Network" on the left side, and then see all of the devices on my home network (while the VPN was connected). Am I missing something obvious? How do I make this happen?

• Settings what-opens-what once and for all (Backing up File Associations)

  - by ldigas

  Every time I switch machines (as in, get a new one, or reinstall an OS or something like that) my precious file associations get lost. And the next six months pass slowly until I again set them up right. Is there a program that allows me to: Set all the extensions I would like to open with let's say, Vim, without setting each one of them individually. Something of a kind: Vim opens: .... list of extensions ... and/or A program which lets me backup my current settings, and when I copy those to a new machine it lets me just modify the paths where I putted the applications in question, and it does the rest (again, associates that program with all the extensions it opened before).

• samsung netbook OS for clean install

  - by Alex

  Hello - I recently had a problem with a corrupted registry on a samsung N120. When all else failed i reformatted the drive. However having bought the machine with windows home ed pre-installed, I didn't have original windows disck for the clean install. So I managed to install another edition of windows XP (PRO this time). Now windows opens, but several key functions are missing. e.g.: screen resolution - will not allow me any but 800x600 resolution native buttons - such as the fn + screen brightness is not working at all. Any suggestions please? ? Is there a way to get the samsung OS online (since I do have the manufacturer's/installed product key)? thanks PS: It has been my intention to install ubuntu, but i need to know i will not lose functions like screen brightness, volume, and the trackpad's scrolling function. I'd be happy to bypass the windows option if i was sure to have full keyboard/samsung functionality

• Why does Mac OS X auto-mount the (disabled) home folder?

  - by NStal

  I've just bought a MacBook Pro. Now I'm trying to build up a filesystem (just some path) that looks like my Ubuntu server. By doing so, I can reuse a lot of the scripts I've written before. I found that Mac OS X auto mounts home with map auto_home, which prevents me from even making a symbolic link. I managed to solve this problem from the solution here. It mentioned that Time Machine will auto-exclude the home folder. But I'm wondering why, this is confusing.

• remoting to pc's already setup with pocketcloud

  - by KiloJKilo

  I use pocketcloud to remote desktop into my PCs on my home network. I would like to remote desktop with windows on my laptop via windows 7, but I'm not really sure how to, without breaking pocketcloud's connection. Does pocketcloud change my router's port forward to each machine as needed? Is there a way I can piggyback on the pocketcloud app? It appears to use 3389 but nothing is routed on that port in my router. Any ideas on how to accomplish this?

• Connections to Cotendo CDN servers are unreliable

  - by user139050

  I've been having a lot of trouble viewing certain websites - Gawker Media, DeviantArt, etc. - and through further investigation they all appear to be using a CDN called Cotendo. On my machine, and only this one, connections reset themselves midway through the download most of the time. This is not browser-specific; even wget (Cygwin) is unable to download anything without retrying a few times. This happens inside virtual machines as well. Unfortunately, I'm pretty stumped on why this is happening. My hosts file is empty (except for a couple LAN-specific things) and I've checked a few different DNS servers, but I can't really think of anything else to try. Anyone have any ideas?

• CentOS running inside VMware as WebServer times out on outside connection [migrated]

  - by Tom Hart

  I have a CentOS machine running inside VMware, and I have got PHP and Apache set up on it, so if I open a browser (on the VM) and go to either localhost, or 192.168.0.3, I get a phpinfo page I made in /var/www/html/index.php, but, if on the host (Windows 7), in my browser I go to 192.168.0.3, it times out. I can ping the IP address from Windows and get a response, I just can't through the browser. Does anyone have any ideas what I need to do to get this working? This is my first time using a VM and I'm getting lost in the network settings.

• Speed up connection to MySQL

  - by Leonick

  So here's one for you. Any idea on a way to shorten the time it takes to connect to a MySQL database? The reason I'm wondering is because I find that just connecting to the DB adds just over a second to the rendering of the page and that seems a bit long considering Apache and MySQL is running on the same machine and the mysqli_connect is connecting to localhost. It's just such a shame when the connection takes a second while any query I end up doing won't add any significant amount of time to the render/load time. Any ways to shorten the time it takes to open a connection?

• Forwarding audio like X in SSH

  - by Akilan

  While it is possible to use X applications remotely by using -X switch in ssh, the sound is being played in remote machine's speaker only. For example if I view a film in VLC/Totem only video is visible and I can't hear the audio. Is there a way to forward audio too? [without digging through Pulse-audio's setup, I mean; Like how ssh understands X forwarding by itself.] I have tried this only in Ubuntu (in various Ubuntu versions from 9.10 through 10.10), if that helps.

• Vagrant and cups port forwarding not working. Not accessible

  - by AAlvz

  I'm working with vagrant and I'm trying to use it as a printing server. I installed cups. Internally everything works just fine. I can even make a quick curl to my localhost:631 (cups port inside my vagrant) and there's everything. The thing is I can't access it in any way I try from the host machine. Obviously I forwarded the port and I've tried with several ports. I've also tried with Debian squeeze and Ubuntu 12.04. Here is my current Vagrantfile Vagrant.configure("2") do |config| config.vm.box = "guruDebian" config.vm.network :forwarded_port, guest: 80, host: 8080 config.vm.network :forwarded_port, guest: 631, host: 6363 ## HERE IS CUPS end Any ideas? ... I'll upload any file if necessary.

• Slow Crash with Filter Manager

  - by Alex N.

  I have been having sporadic freezes on my machine lately. There is no blue screen or crash screen. All the applications just stop responding and ~5~10 minutes later it will power off. After checking the event log a couple times, I have found that the same event occurs right before each crash. File System Filter 'Avgmfx64' (6.1, ?2011?-?12?-?23T08:08:12.000000000Z) has successfully loaded and registered with Filter Manager. My question is twofold: I can not seem to find any information on what the Filter Manager actually is supposed to do. for curiosities sake, what is it? And more importantly, how do I fix this problem. From the research I have done, I see that similar problems can be caused by out of date drivers, so I have already taken the time to update all of my drivers, run MemTest, and verify the drive integrity.

• Why is the word PERSONAL still relevant in the term PC? [closed]

  - by Bill

  I have spent half an hour trying to change an icon on my Win-7-64 machine (Why Can't I Change the Icon). One reasonable suggestion (reasonable in terms of having a solution, not reasonable in terms of having to jump through these hoops for such a basic requirement) was to delete the old icon from the %userprofile% \ Local Settings..., however when I click on this folder in Windows Explorer I am told the folder is not accessible - Access Denied. Well! It's my PERSONAL computer isn't it? Isn't that what PC stands for? It's MY computer - why can't I get access to that folder? It's about time we started calling these machines MCs (Microsoft Computer), or WCs (Windows Computer) - because they sure as hell aint PERSONAL damn computers!!!!

• How can I retrieve "remembered"(stored) wi-fi password from a win. 7 device?

  - by user180880

  I have access to PC, and I am a standard user. Everything(incl. "show charecters" tickbox at wiriless menu) requires admin access. Now, that said machine is actually like a big tv with touch. Type-stuff is handled by virtual keyboard of windows. I can reach to c:\ProgramData\Microsoft\Wlansvc\Profiles\Interfaces and can see-open files there, which is I assume where passwords stored are. Now the problem is that these passwords is encypted. I'm ok with if there is a way with changing/resetting admin password as well. Considering this device has nothing but massive amounts of usb(yep, not even cd-dvd // rw) the only way is from inside or with usb without admin rights.

• Find an old static IP address on a mac backup?

  - by Joe

  I have an old backup of a mac via time machine, and I was wondering if there is some sort of accessible file that would have the static IP of the old computer it was backed up from. If you are curious, I am in IT and it is a PITA to get a new static IP here. I am just trying to use the old one to save some hassle. I've tried searching through the system log with no success (but I might be doing it wrong- grep with a regexp for an IP). Thanks!

• Changing Chrome Working Directories on Mac clients

  - by Jason

  We're using Mac OSX 10.6.8 with NFS for home directories. Chrome seems to not like this, for a user who is logged in more than one machine. AFP was ok, but for other reasons we need NFS. It only allows you to start one instance. Ie, userA logged in to Mac1, Mac2. Can only have chrome open on Mac1 OR mac2, not both. I have read at this thread, changing working directory, and sym link can fix... but I can't find the details. Can someone help?

• Can't get to the login screen

  - by Rod

  I upgraded my wife's Windows 7 machine, to Windows 8 Pro, about 10 days ago. She's been using it fine ever since. We typically leave our desktops running 24/7, and just turn off the monitor. This morning she turned the monitor on, and saw the screen with the Seattle Space Needle, and then she pressed the enter key to get to the login screen. Nothing happened. Next she pressed the mouse key. Nothing happened. The mouse moves around fine. But we can't get it past the Seattle Space Needle screen. She replaced the batteries in both her keyboard and mouse recently. So, what's going on? How do we fix it?

• Moving a "All-in-one" PC when turned on/off.

  - by Purak

  I have an "all-in-one" pc. I know that moving a pc when it is switched on is harmful to the hardware components. What I would like to know is if the same applies to "all-in-one" pc's and if the same applies to regularly moving it from one side of the room to the other when it is turned off! The reason for the question is that I work on one desk during the day, and in the evening move it to the couch so I can do other stuff while watching TV or something. I always turn it off before the move, but somebody told me that I can be damaging the machine by doing so. Can anybody shed some light on this? Many thanks

• Restrict whole system on certain cores except a few process?

  - by icando

  Hi I am running some latency sensitive program on a Linux machine (more specifically, CentOS 6), and I don't want the threads of the process being preempted. So in my plan, the first step is to set cpu affinity of the threads so that threads are running on separate cores, so they don't preempt each other. Then the second step is to make sure other processes in the system not running on these cores. So my question is: is it possible to restrict the whole system running on certain cores, except this process? This should apply to any newly created processes in the future.
