  • Will having multiple domains improve my seo?

    - by Anonymous12345
    Lets say I have a domain already, for example www.automobile4u.com (not mine), with a website fully running and all. The title of my "Website" says: <title>Used cars - buy and sell your used cars here</title> Also, lets say I have fully SEO the website so when people searching for the term buy used cars, I end up on the second or first page. Now, I want to end up higher, so I go to the google adwords page where you can check how many searches are made on specific terms. Lets say the term "used cars" has 20 million searches each month. Here comes the question, could I just go and buy that domain with the search terms adress, in this case www.usedcars.com and make a redirect to my original page, and this way when people search for "used cars", my newly bought domain name comes up redirecting people to my original website (www.automobile4u.com)? The reason I believe this benefits me is because it seems search engines first of all check website adresses matching the search, so the query "used cars" would automatically bring www.usedcars.com to the first result right? What are the downsides for this? I already know about google spiders not liking redirects, but there are many methods of redirecting... Is this a good idea generally?

  • Can I tell which installation DVD was used for my Windows XP?

    - by Den
    I have two Windows XP installation DVDs (that came from the OEM with my two laptops). I need to reinstall Windows on one of them but I'm not sure which one is which. Is there any way to tell which DVD was used for each laptop? PS. They both came from the same OEM and there're no distinguishing markings on the DVDs themselves. PS2. The reason for my concern is to avoid installation twice, which may invalidate license for already installed Windows XP on one laptop if I duplicate it to another.

  • VMware 1.0.1 Windows7 - Ubuntu hostnames

    - by Kyle K
    I'm trying to run Ubuntu as the guest OS using VMWware 1.0.10 with Windows 7 Ultimate as the host OS. I had this set up previously with Win XP as the host OS and in fact I'm using the same .vmx My problem is I can't get either Win7 or Ubuntu to be able to ping the other by hostname. After installing Samba and Winbind on Ubuntu, I was able to get this working when under WinXP, but for some reason I can't get it to work under Win7. I can ping by IP Address, and the guest OS even shows up by hostname under the Windows networking panel (but of course I can't do anything with it), but pinging using short hostnames just won't work. Also, Win7 firewall is turned off completely.

  • how to properly implement alpha blending in a complex 3d scene

    - by Gajet
    I know this question might sound a bit easy to answer but It's driving me crazy. There are too many possible situations that a good alpha blending mechanism should handle, and for each Algorithm I can think of there is something missing. these are the methods I've though about so far: first of I though about object sorting by depth, this one simply fails because Objects are not simple shapes, they might have curves and might loop inside each other. so I can't always tell which one is closer to camera. then I thought about sorting triangles but this one also might fail, thought I'm not sure how to implement it there is a rare case that might again cause problem, in which two triangle pass through each other. again no one can tell which one is nearer. the next thing was using depth buffer, at least the main reason we have depth buffer is because of the problems with sorting that I mentioned but now we get another problem. Since objects might be transparent, in a single pixel there might be more than one object visible. So for which Object should I store pixel depth? I then thought maybe I can only store the most front Object depth, and using that determine how should I blend next draw calls at that pixel. But again there was a problem, think about 2 semi transparent planes with a solid plane in middle of them. I was going to render the solid plane at the end, one can see the most distant plane. note that I was going to merge every two planes until there is only one color left for that pixel. Obviously I can use sorting methods too because of the same reasons I've explained above. Finally the only thing I imagine being able to work is to render all objects into different render targets and then sort those layers and display the final output. But this time I don't know how can I implement this algorithm.

  • Laptop's wifi router is not emitting signals therefore my PC and Nokia cell are not connecting to internet

    - by umer sanny
    I have a USB internet connection which I plugged into my laptop. I converted my laptop's Wifi into a Wifi router so that I can attach my PC and cell to this network and enjoy internet, but it doesn't work. I have a Dell Inspiron N5110 i7 Windows 7 64-bit laptop, Dell D865 PC and Nokia C5. My PC and cell are showing that there is a new Wifi connection available, but when I connect to it, it won't load any web page. Reason is my laptop's Wifi is not emitting any internet signals or may be some other issue which i dont know.. laptop's adapter is 802.11b/g/n I don't know why. How can I enjoy Wifi internet on laptop, PC and cell at the same time?

  • How can I get nvidia-96 installed?

    - by Bob
    I'm at my wits end here. This is my last effort before I go back to Windows. I need to get nvidia-96 proprietary driver installed. Synaptic won't install it because it says it has dependencies. I installed every single dependency it listed except for "xorg-video-abi-10" which does not show up as an item that can be installed. I have no idea what to do. Using 11.10 with a NVIDIA Geforce 3 GPU. Anyone know how to get this dang driver installed? @fossfreedom: the opensource driver is extremely slow. So slow that the OS is unusable—words appear seconds after I type them—programs take forever to perform actions. Also it is causing my monitor to turn on and off for no reason. @yossile: synaptic shows that I have xserver-xorg-core installed. And xserver-xorg-core-udeb does not show up as something that can be installed. @papseddy: when I try to install the downloaded nvidia driver it says it won't work until I disable Nouveau kernel driver. I have tried everything to get this dang Nouveau kernel driver disabled. Nothing has been successful.

  • What is the difference between a plain Amazon ec2 instance and beanstalk?

    - by Alex Ford
    I am a solo developer and the sites I'm deploying are very small, usually hobby sites and I have a few questions about the Amazon services. Is there a reason for me to use beanstalk or should I just stick with a single ec2 instance? Should I use RDS for database? I heard someone say that I could just install a database on my ec2 instance, making it cheaper. I'm trying to keep everything as cheap as possible. I need to point custom domains to my sites. Pretty sure that means I have to deal with elastic IPs. Do those work with beanstalk or only with individual ec2 instances? Thanks in advance!

  • backface culling error

    I write simple software renderer. In my pipeline i have stage of backface culling. But looks like it has some error (see picture). I perform culling right after world transformation.

  • Commands don't have permission when using absplute path

    - by Markos
    I have folders set up this way: /srv/samba/video getfacl /srv/samba/video # file: srv/samba/video # owner: root # group: nogroup user::rwx group::--- group:sambaclients:rwx group:deluge:rwx mask::rwx other::--- default:user::rwx default:group::--- default:group:sambaclients:rwx default:group:deluge:rwx default:mask::rwx default:other::--- That means, user deluge has rwx to folder /srv/samba/video. However, when running command as user deluge, I am getting weird permission errors. When in folder /srv/samba/video: sudo -u deluge mkdir foo works flawlessly. But when using absolute path: sudo -u deluge mkdir /srv/samba/video/foo I am getting permission denied. When running sudo -u deluge id, I get output uid=113(deluge) gid=124(deluge) skupiny=124(deluge) which shows that user deluge is indeed in group deluge. Also, the behavior was the same when I gave the permissions also to user deluge not just group deluge. When executing as non-system user, it does work. The reason that I want to use absolute paths is that I am using automatically triggered post-download script which extracts some files into the folder. I have spent way too many hours to solve this problem myself. mkdir isn't the only command that fails, touch is doing the same thing, so I suspect that it's not mkdir's fault. If you need more info, I will try to put it in here, just ask. Thanx in advance.

  • modprobe ndiswrapper - not found

    - by David
    I'm trying to use ndiswrapper on a Slackware 12 (I think) box, but I'm running into a problem with modprobe. Everything I find online says that it should be working, but for some unknown reason it isn't. Here's what I've done so far: Installed ndiswrapper (latest tarball, make, make install) Ran ndiswrapper -i on the WinXP driver for my USB wireless card Ran ndiswrapper -l which tells me the driver is present and the device is present (lsusb also confirms the device is present) Ran ndiswrapper -m which put an alias for wlan0 in /etc/modprobe.d/ndiswrapper.conf Ran depmod -a Ran modprobe ndiswrapper which tells me "FATAL: module ndiswrapper not found" Ran modprobe -l which shows no listing for ndiswrapper I even tossed in a reboot or two while trying various combinations of the above, still nothing. So naturally ifconfig wlan0 up isn't working because the device isn't being created, presumably because the module isn't loading the driver. Does anybody have any suggestions? Everything points to the notion that this should work fine, but modprobe just isn't able to find what it needs. Have I missed an important step?

  • Using Cygwin in Windows 8, chmod 600 does not work as expected?

    - by Castaa
    I'm trying to change the the permissions to my key file key.pem in Cygwin 1.7.11. It has the permissions flags: -rw-rw---- chmod -c 600 key.pem Reports: mode of 'key.pem' changed from 0660 (rw-rw----) to 0600 (rw-------) However: ls -l key.pem still reports key.pem's permission flags are still: -rw-rw---- This reason why I'm asking is that ssh is complaining: Permissions 0660 for 'key.pem' are too open. when I try to ssh into my Amazon EC2 instance. Is this an issue with Cygwin & Windows 8 NTFS or am I missing something?

  • Newly added virtualhost not working, domain points to /var/www/

    - by Morgan
    I've had no problem with vhosts before, but for some reason this one isn't pointing to the right document root. The domain is pointing to the correct IP, apache sees no errors with the config file in sites-available, yet it just isn't pointing correctly. Here is the vhost config for the domain: <VirtualHost *80> ServerAdmin [email protected] ServerName mydomain.info ServerAlias www.mydomain.info DirectoryIndex index.html DocumentRoot /var/www/vhosts/mydomain.info/htdocs LogLevel warn ErrorLog /var/www/vhosts/mydomain.info/log/error.log CustomLog /var/www/vhosts/mydomain.info/log/access.log combined </VirtualHost> For the record, I am running Apache2 on Ubuntu 12.10

  • Kaspersky processing error Explorer.exe (recycle bin)

    - by aeternus828
    I get daily critical errors from Kaspersky involving Explorer.exe... The file in question is almost always in the Recycle Bin, or something on the desktop. Here is an example error detail: Event type: Processing error Application\Name: EXPLORER.EXE Application\Path: C:\WINDOWS\ Application\Process ID: 2364 Application\Options: C:\windows\Explorer.EXE Component: File Anti-Virus Result\Description: Processing error Object: C:\$Recycle.Bin\S-1-5-21-1403139956-787289773-2644151291-500\$RIKKQKS Object\Type: File Object\Path: C:\$Recycle.Bin\S-1-5-21-1403139956-787289773-2644151291-500\ Object\Name: $RIKKQKS Reason: Read error Google searches didn't offer much insight, so I thought I'd ask here if anyone has encountered a similar situation.

  • Moving data to lower sectors on an SSD without defragging

    - by David Freitag
    I bought an Intel SSD drive a while back and now I want to dual-boot with it. But for some reason there are sectors near the end of the drive filled and I can’t seem to find a way to remove the data so that I can safely shrink the partition. I know I have sectors near the end full because I am using Defraggler to analyze my drive (not to defrag it). I can see what files need to be moved/deleted but short of actually deleting some drivers and/or other necessary files, I am completely stuck. This the diskmap: I am only able to shave off that last 1.72GB of space from the drive which isn’t even enough for the most minimal Linux install.

  • PHP won't run on Fedora 15

    - by George
    I have followed this exact tutorial on installing php on a Fedora 15 system. I have all the necessary packages installed with no errors. Yet the simple phpinfo() test page will show - it will show a blank page. When I try to see the source, I see it downloaded my .php file as plain text and loaded it in the browser. So I am guessing for some reason php module is not loaded in httpd. Does anyone have any idea why? P.S. I am really hoping SELinux this time has nothing to do with this!

  • Trying to install Proprietory Nvidia Graphics Drivers

    - by Peter Snow
    After reading and trying many different suggestions for some hours, I returned to this how-to: https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia The first problem I encounter is how to identify which of the listed drivers support my Nvidia GEForce 630M graphics card. Following the links doesn't really help, since it is not stated there either (except where support for a new driver was added later which is explicitly stated, but the original devices covered are not). However, even if I knew, if it doesn't appear in the 'Additional Drivers' dialogue (see below), how will I install it? Second Issue: The article goes on to say that available drivers for my hardware are usually listed in 'Additional Drivers'. In my case, they aren't. Unfortunately, it doesn't tell me how to correct that or work around it? I've checked the bios and there is no way offered there to disable the integrated graphics, only the Nvidia graphics. I've also tried each available option in this: $ sudo update-alternatives --config i386-linux-gnu_gl_conf My system is an Acer Aspire 4752G bought May 2012. I'm running Ubuntu 12.04LTS. uname -a : 3.2.0-38-generic-pae #61-Ubuntu SMP Tue Feb 19 12:39:51 UTC 2013 i686 i686 i386 GNU/Linux It's 64bit hardware but I installed 32bit OS for greater software compatibility. Running $ sudo tail -fn 500 /var/log/Xorg.0.log | grep '(EE)' returns" (WW) warning, (EE) error, (NI) not implemented, (??) unknown. [ 28.886] (EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found) The reason for wanting the proprietor y drivers is because my laptop comes with 3D accelerated graphics adaptor and so rather than confining myself to struggling with the on-board graphics, I would rather use it. I also want to experiment with using it for bitmining (which uses the GPU's for computing power).

  • Should you always pass the bare minimum data needed into a function

    - by Anders Holmström
    Let's say I have a function IsAdmin that checks whether a user is an admin. Let's also say that the admin checking is done by matching user id, name and password against some sort of rule (not important). In my head there are then two possible function signatures for this: public bool IsAdmin(User user); public bool IsAdmin(int id, string name, string password); I most often go for the second type of signature, thinking that: The function signature gives the reader a lot more info The logic contained inside the function doesn't have to know about the User class It usually results in slightly less code inside the function However I sometimes question this approach, and also realize that at some point it would become unwieldy. If for example a function would map between ten different object fields into a resulting bool I would obviously send in the entire object. But apart from a stark example like that I can't see a reason to pass in the actual object. I would appreciate any arguments for either style, as well as any general observations you might offer. I program in both object oriented and functional styles, so the question should be seen as regarding any and all idioms.

  • Google Analytics Visitors drop-off for certain region of site only

    - by crmpicco
    I have an issue with the tracking on my site where I have seen a dramatic drop off of visitors to the site from a certain region. I have four regions on my site at the moment, these are UK, EU, US and RoW (Rest of the World). The UK, EU and US regions are unaffected, only the RoW region suffers this drop-off. I have included a screen shot below from my GA account, which shows this effect. My GA code, which is included on every page on the site is below. I have changed the UA account number intentionally for this example. There have been no changes made to the GA account or the tracking code in a live environment for some considerable time, but for some reason I am seeing the drop-off for this region only. In the code below I am not tracking page views on certain pages as I have event tracking setup for these pages. <script type="text/javascript"> var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-18721873-5']); _gaq.push(['_setCookiePath', '/row/']); if ( typeof(p_page) != 'undefined') { // do nothing if user is on above pages // N.B. there are a series of conditions in this if statement checking that we are not on a particular page } else { _gaq.push(['_trackPageview']); } </script>

  • Cron Script to Delete Folder Contents Every 5 Minutes on Media Temple

    - by Brian Iannone
    I'm not familiar with server-side scripting, but I'm currently using a PHP application on Media Temple to cache JPEGs from four webcams hosted on a server located in the middle of the Indian Ocean. (Hence my reason for caching them in the US.) The webcams are updated every five minutes. The PHP application stores the cached images in http://static.rigic.co/cache/. I would like to create a cron script to automatically delete the contents of "cache" (not the folder itself; just the files inside) at a regular interval.

  • Copy contents of a folder, but none of its subfolders?

    - by wizlog
    I'm using the explorer bar (the bar to the left of the main folder/files section in an explorer window) to show folders. I don't have access to open any of the folders, themselves (at least none on C:\ (the C drive). For some reason, I do however have copy rights (I can copy the folders). Because I can only see the folders, is there a way for me to copy the main folder, but not any of the subfolders? A localized example could be how to copy all files in C:\documents...[user]\my documetns\ but none of the folders (ex. C:\documents...[user]\my documetns\my pictures...) Is there a way for me only to copy a folder, but not its subfolders?

  • HTTP resource caching / fetching

    - by Bobby Jack
    I'm trying to optimise a page, and I'm seeing some strange behaviour. Each time I click on a link to the page, all resources are fetched from the server, responding with 200s. However, when I refresh the page (specifically, F5 in Firefox), all resources return a 304 and - of course - the page loads much faster as a result. The main page returns a 200 in both cases. In the refresh case, If-Modified-Since headers are sent with the requests to the resources. However, in the 'clicking a link' case, they are not. What's the reason for that, and can I control it?

  • In Windows XP, is it possible to disable user credential caching for particular users

    - by kdt
    I understand that when windows caches user credentials, these can sometimes be used by malicious parties to access other machines once a machine containing cached credentials is compromised, a method known as "pass the hash"[1]. For this reason I would like to get control over what's cached to reduce the risk of cached credentials being used maliciously. It is possible to prevent all caching by zeroing HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\CachedLogonsCount, but this is too indiscriminate: laptops users need to be able to login when away from the network. What I would like to do is prevent the caching of credentials of certain users, such as administrators -- is there any way to do that in Windows XP? http://www.lbl.gov/cyber/systems/pass-the-hash.html

  • Weird 302 Redirects in Windows Azure

    - by Your DisplayName here!
    In IdentityServer I don’t use Forms Authentication but the session facility from WIF. That also means that I implemented my own redirect logic to a login page when needed. To achieve that I turned off the built-in authentication (authenticationMode="none") and added an Application_EndRequest handler that checks for 401s and does the redirect to my sign in route. The redirect only happens for web pages and not for web services. This all works fine in local IIS – but in the Azure Compute Emulator and Windows Azure many of my tests are failing and I suddenly see 302 status codes where I expected 401s (the web service calls). After some debugging kung-fu and enabling FREB I found out, that there is still the Forms Authentication module in effect turning 401s into 302s. My EndRequest handler never sees a 401 (despite turning forms auth off in config)! Not sure what’s going on (I suspect some inherited configuration that gets in my way here). Even if it shouldn’t be necessary, an explicit removal of the forms auth module from the module list fixed it, and I now have the same behavior in local IIS and Windows Azure. strange. <modules>   <remove name="FormsAuthentication" /> </modules> HTH Update: Brock ran into the same issue, and found the real reason.

  • script to automatically test if a web site is available

    - by Xoundboy
    I'm a lone web developer with my own Centos VPS hosting a few small web sites for my clients. Today I discovered my httpd service had stopped (for no apparent reason - but that's another thread). I restarted it but now I need to find a way that I can be notified by email and/or SMS if it happens again - I don't like it when my client rings me to tell me their web site doesn't work! I know there are probably many different possibilities, including server monitoring software. I think all I really need is a script that I can run as a cron job from my dev host (which is permanently running in my office) that attempts to load a page from my production server and if it doesn't load within say 30 seconds then it sends me an email or SMS. I'm pretty rubbish at shell scripting, hence this question. Any suggestions would be gratefully appreciated, thanks to all you clever sysadmin guys and girls out there :)

  • Computer turns off and on after start ..then goes dead

    - by Shiki
    I built a new PC from the following components: - CPU: Intel Core i7 950 - MB: Gigabyte X58A-UD3R - RAM: 2x2gb i7 Corsair memory - VGA: Zotac AMP2 GTX260 - HDD: 1 GreenSATA HDD (Western Digital 500gb RE2) When I turn it on, it goes for a few seconds, fans at maximum speed, then turns off. The again, it starts by itself.. and goes with fans on max speed, nothing happens. First I suspected my PSU. It's a Chieftec 450AA PSU. After I borrowed a Chieftec 550AA PSU, I tried to start with that. Exact same story. Any idea ? Do I need a bigger PSU? Reason why its not localized. I never seen this turn on, off, on. If you give answer for that, it would already help people like me, with the same problem.
