  • Dual boot centOS and Win7

    - by user1855965
    I posted this on stackoverflow, but it looks like superuser would be more appropriate. I have a CentOS 5 machine that runs Windows 7 as a dual boot. CentOS is the main OS and each OS is set up in a specific hard drive. This was set up before I joined the company and I don't really have need to run Windows now. My question is: can I, from CentOS, reformat the Windows HD, change GRUB settings and get the HD to be available on CentOS? Happy to provide more info if this helps. Many thanks for your help and apologies if this is a very simple issue... I don't want to blindly test things on this machine as it is used on a daily basis by several users.

  • Windows Server 2012 is telling me it's not activated when it is

    - by LeonidasFett
    I have a Windows Server 2012 Machine were I need to do some development. The machine is a Hyper-V VM. I activated it with a valid key and restarted the VM. After it booted up again, I went into system properties and saw that it said that Windows is activated. However, there is still the message "Activate Windows" on the desktop wallpaper and if try to change something (for example, the look) it tells me that I need to activate first. Is there anybody who has experienced this? The host OS is Windows 8.1. I already installed all updates and tried to activate again using this CMD-Command: slmgr.vbs /ipk {product key, including dashes}

  • How do I turn of "auto-echo" in bash when I 'cd'?

    - by Avery Chan
    I don't know when this started happening but now, every time I cd to a directory it echoes the path right before it changes directories. This happens when I log into a server but doesn't happen on my local machine. The server is running Linux. My local machine is running Mac OS X. I searched the Google as well as looked at the bash man page but I couldn't find anything. My .bashrc/.bash_profile doesn't have anything related to 'cd' (that I know of). How do I modify this "feature"?

  • Can't access the Internet in VMware Workstation

    - by asunnysunday
    I'm using VMware 7.1.2 in Windows 7 with Ubuntu 11.04 as a guest OS. In the host OS (Windows 7), I can access the Internet without any problems but in the virtual machine I can't access the Internet. I've tried the following but with no success: Use all methods of connecting to the Internet in "Virtual Machine Settings": Bridged, NAT, Custom; none work. Used cabled and wireless connections on the PC - neither of them work. I've used Ubuntu in VMware for several months - previously the Internet was always accessible. Could the cause of this be because I upgraded to Ubuntu 11.04?

  • Fastest approach to 3D animation

    - by HappyFerret
    I'm currently tasked with designing a small HTML5 game. Having done everything by myself so far (3D models, codebase, game design, etc) I'm now at a point where I'm running out of time. I've less than a day to animate and bind everything together. However, that's exactly my problem. I was under the naive impression that everything would be easier if I went with pre-rendered 3D models. However, I didn't consider the most difficult part. Animation. After having spent over an hour trying to figure out messiahStudio, I figured it's time to ask for outside help. Is there any easier solution to 3D animation than 3D rigging? What I'm basically looking for is some sort of tool that allows me to simply grab and move/deform select polygons. It doesn't have to be as life-like and accurate as rigging, just efficient enough. Were the circumstances any different, I might just learn how to rig. But that's sorely out of scope right now. PS:The models were created in Sculptris but are fairly low-poly.

  • Podcast online sync service

    - by Hannes de Jager
    I download and listen to podcasts on 2 different computers. I would like so somehow sync the metadata such that, when I subscribe to a feed it gets subscribed on my other computer also. When I've downloaded a podcast it gets marked as downloaded on the other machine also. Is there a software + webservice combination that will allow me to do this. That will save its doings to the cloud and update it also? My one machine is Windows and the other one Linux.

  • How to add a VM Server to a VM Domain when the host is not on that domain.

    - by Charlie
    I have created A VM running Windows Server 2008 R2, using VMWare. I have configured this as a domain controller running a Windows Server 2008 domain. I have also created another VM running Windows Server 2008 R2. The HOST machine is using Windows 7 Professional 64 bit. When I try to add the second VM into the domain that the first is the DC for it fails as the VM cannot contact the DC. Simple question really. What have I missed? Is it something to do with the configuration on the Host machine? What do I need to do to enable this scenario? Thanks

  • Do you leave Windows Automatic Updates enabled on your production IIS server?

    - by Nobody
    If you were running a 24/7 website on Windows Server 2003 (IIS6). Would you leave the Windows automatic update feature enabled or would you turn it off? When enabled, you always get the latest security patches and bug fixes automatically as soon as they're available, which is the most secure choice. However, the machine will sometimes get automatically rebooted to apply the updates leading to a couple of minutes of downtime in the middle of the night. Also, I've seen rare occasions where the machine does not restart correctly resulting in further downtime. If auto updates are off, when do you apply the patches? I guess you have to use a load balancer with multiple web servers and rotate them out of the production site, apply patches manually, and put them back in. This can be logistically inconvenient when the load balancer is managed by a hosting company. You will also have machines in production that don't always have the latest security patches and you have to routinely spend time deciding which patches to apply and when.

  • can't run binaries or shell scripts

    - by hyperboreean
    I am running Debian testing and I am not able to run any binary or shell script. I keep getting "No such file or directory". The umask is the default one and I haven't fooled around with the paths. Also, I am aware of this question, but it doesn't work out for me - I compiled my code on this machine and trying to run it on the same machine. Also, all of my shell scripts have the correct shebang. Any advices?

  • Error 5A - Internal CPU Error

    - by Mitch
    So I built myself a pc for the first time. The machine has been running properly, and without issue, since March of this year. Today after an hour or so of gaming the machine shutdown without warning. Any attempts to reboot have been unsuccessful. I have managed to get it to post, twice, but it doesn't get as far as the OS before it shuts off again. I pulled the second video card so I could see the error code LED and it appears to be showing 5A which matches to "Internal CPU Error". Am I looking at a failed CPU or is this a symptom of another issue? Any feedback you can provide is most appreciated. Here's my parts list: CPU: Intel Core i7-4930K 3.4GHz 6-Core CPU Cooler: Corsair H105 73.0 CFM Liquid Motherboard: Asus X79 Deluxe ATX LGA2011 Ram: G.Skill Ripjaws X Series 32GB (4 x 8GB) DDR3-1600 Video card (x2): EVGA GeForce GTX 770 2GB Power supply: Corsair 1000W ATX12V / EPS12V

  • Linux - Network Sharing a local NTFS usb drive

    - by Jonathan Rioux
    I have an external hard drive formated in NTFS which I would like to be able to access by the network. I want to make a network share out of it. I also have a Debian machine running in my house and I then got an idea. I want to plug in my external hard drive (usb) into my Debian machine, and make a windows share with it, maybe with Samba, so I will be able to access it from my Windows 7 laptop and see it as a network share. Additionally, how can I restrict specific folders of that network share, and allow only specific folders to specific users? For instance, I would like to give my girlfriend access to a folder of her name so she can put her files and so she wont be able to see the stuff in my folder...

  • Why are my Google searches redirected?

    - by Please Help
    This machine was infected with various malware. I have scanned the system with Malwarebytes. It found and removed some 600 or so infected files. Now the machine seems to be running well with only one exception. Some Google search results are being redirected to some shady search engines. If I were to copy the url from the Google Search results and paste it in the address bar it would go to the correct site but if I click the link I will be redirected somewhere else. Here is my log file from HijackThis: http://pastebin.com/ZE3wiCrk

  • Send Ctrl+Alt+Del over VNC with Windows Vista and UAC off?

    - by jasonh
    I'm trying to set up a machine here with UltraVNC on Windows Vista with UAC off. The problem is, in this configuration, I can't send Ctrl + Alt + Del (CAD) to the Windows Vista machine, and so I'm stuck at the login screen, which is waiting for the CAD sequence. I'm joined to a domain, so I don't think I can disable the CAD requirement. I can't re-enable UAC either. I also tried using the on-screen keyboard, but it didn't seem to work. Is there a workaround or a solution?

  • Linux PHP web server horribly slow when accessed from any windows browser

    - by Ed Harcourt
    I have a Linux server (Ubuntu 10.04) running apache2 and PHP. Everything runs fine when accessing a page from any browser from another Linux machine or Mac. But when I try to access a page from any combination of Windows machine and browser I get about a 30 second delay before the page comes back. Accessing a plain old HTML file from the Windows browser runs lickity split. So it seems to be just PHP. MySQL is installed but a simple test page that uses no MySQL is still slow. I don't think it is DNS because if I hard code the IP address in the URL nothing changes. There doesn't seem to be anything in the log files that I can tell. What could be causing this behavior on Windows clients?

  • How can I make my PHP development environment more efficient?

    - by pixel
    I want to start a home-brew pet project in PHP. I've spent some time in my life developing in PHP and I've always felt it was hard to organize the development environment efficiently. In my previous PHP work, I've used a windows desktop machine and a linux server for development. This configuration had it's advantages: it's easy to configure Apache (and it's modules)/PHP/MySql on a linux box, and, at the time, this configuration was the same like on production server. However, I never successfully set up a debug connection between my Eclipse install and X-debug on server. Transferring files from my local workspace to the server was also very annoying (either ftp or Bazaar script moving files from repository to web root). For my new setup, I'm considering installing everything on my local machine. I'm afraid that it will slow down workstation performance (LAMP + Eclipse), and that compatibility problems will kick-in. What would you recommend? Should I develop using two separate machines? On one? Do you have experience using one of above configurations in your work?

  • Snow Leopard Windows 7 File sharing issue

    - by nsiggel
    Hello, wondering if anyone might have any suggestions on how to fix this issue in file sharing between Snow Leopard and Windows 7. On my home network, I have a system running windows 7 which acts as a file server: \WINDOWS7-A\SHARE I also have an IMac which can access the file share most of the time.... however now comes the problem, as soon as I introduce my Windows 7 Laptop and copy files over from it onto the file server (\Windows7-A), the file server become no longer accessible from the Snow Leopard machine... I assume this somehow has to do with elevated security on the network share having been negotiated between the 2 Windows 7 machines which is no longer allowing the Mac to see the Windows machines... but not sure how to disable this, as the only way I can restore communication between the mac and the Windows 7 machine is to restart it... less than ideal... Any suggestions would be welcome.

  • Solutions for "Maintenance Mode"

    - by Ka Lyse
    Given a web application running across 10+ servers, what techniques have you put in place for doing things like altering the state of your website so that you can implement certain features. For instance, you might want to: Restrict Logins/Disable Certain Features Turn Site to "Read Only" Turn Site to Single "Maintenance Mode" page. Doing any of the above is pretty trivial. You can throw a particular "flag" in an .ini file, or add a row/value to a site_options table in your database and just read that value and do the appropriate thing. But these solutions have their problems. Disadvantages/Problems For instance, if you use a file for your application, and you want to switch off a certain feature temporarily, then you need to update this file on all servers. So then you might want to look at running something like ZooKeeper, but you are probably overcomplicating things. So then, you might decide that you want to store these "feature" flags in a database. But then you are obviously adding unncessary queries to each page request. So you think to yourself, that you will throw memcached in to the mix and just cache the query. Then you just retrieve all of your "Features" from memcached and add a 2ms~ latency to your application on every page. So to get around this, you decide to use a two tier-cache system, whereby you use an inmemory cache on each machine, (like Apc/Redis etc). This would work, but then it gets complicated, because you would have to set the key/hash life to perhaps 60 seconds, so that when you purge/invalidate the memcached object storing your "Features" result, your on machine cache is prompt enough to get the the new states. What suggestions might you have? Keeping in mind that optimization/efficiency is the priority here.

  • What to do about "system running in low-graphics mode"?

    - by ubuntubabe
    My Dell which was 5 years old suddenly karked it and I had the "low graphics" black screen and useless dialogue box. As I believed it was a dead graphics card I went out and bought a brand new machine. I put aside the new machine and tried again in vain to open the Dell. I eventually got to the command line via Ctrl+Alt+F1. I logged into my account from there, and simply started a series of sudo apt-get remove of various softwares that I knew were installed on my PC (software without any great consequence like Google earth, tweak, Skype etc). Lo and behold after a sudo reboot my computer was fine again! So now I have 2 computers. BUT one week after buying the other one and installing 12.04 because I love Ubuntu, the SAME PROBLEM arrived! I once again deleted Google earth, Skype, and did a sudo reboot and everything worked as before. I think there is a bug or something in 12.04 as this problem has never arisen with any other versions of Ubuntu.

  • Copy files off FreeBSD

    - by Josh
    I have a FreeBSD machine that I have to copy everything off the drive. The fielsystem is UFS and not readable by any other operating system. (great...) I have a USB flash drive (FAT32) I need to copy everything to from the SATA in the bsd machine. I looked up cp commands, and got it to partially work, but it seems to copy to the wrong directory. I cannot find out the "name" of the USB drive, and if it can even copy to it.

  • Should we install the OS on an SSD or not when running virtual machines?

    - by Raghu Dodda
    I have a new Dell Mobile Precision M6500 laptop with 8 GB RAM. it has two hard drives - 500 GB @7200 RPM and a 128 GB SSD. The main purpose of these laptop is software development in virtual machines. The plan is to install the base OS (Windows 7) and all the programs in the 500 GB drive, and let the SSD only contain the virtual machine images. It is my understanding that the we get most performance from the virtual machines if the images are on a separate hard drive than the base OS. Is this the way to go, or should I install the OS on the SSD as well? What are the pros and cons? The virtual machine images would be between 20 - 30 GB, and I might run 1 or 2 at a time.

  • How often do you review fundamentals?

    - by mlnyc
    So I've been out of school for a year and a half now. In school, of course we covered all the fundamentals: OS, databases, programming languages (i.e. syntax, binding rules, exception handling, recursion, etc), and fundamental algorithms. the rest were more in-depth topics on things like NLP, data mining, etc. Now, a year ago if you would have told me to write a quicksort, or reverse a singly-linked list, analyze the time complexity of this 'naive' algorithm vs it's dynamic programming counterpart, etc I would have been able to give you a decent and hopefully satisfying answer. But if you would have asked me more real world questions I might have been stumped (things like how would handle logging for an application, or security difference between GET and POST, differences between SQL Server and Oracle SQL, anything I list on my resume as currently working with [jQuery questions, ColdFusion questions, ...] etc) Now, I feel things are the opposite. I haven't wrote my own sort since graduating, and I don't really have to worry much about theoretical things that do not naturally fall into problems I am trying to solve. For example, I might give you some great SQL solutions using an analytical function that I would have otherwise been stumped on or write a cool web application using angular or something but ask me to write an algo for insertAfter(Element* elem) and I might not be able to do it in a reasonable time frame. I guess my question here to the experienced programmers is how do you balance the need to both learn and experiment with new technologies (fun!), working on personal projects (also fun!) working and solving real world problems in a timeboxed environment (so I might reach out to a library that does what I want rather than re-invent the wheel so that I can focus on the problem I am trying to solve) (work, basically), and refreshing on old theoretical material which is still valid for interviews and such (can be a drag)? Do you review older material (such as famous algorithms, dynamic programming, Big-O analysis, locking implementations) regularly or just when you need it? How much time do you dedicate to both in your 'deliberate practice' and do you have a certain to-do list of topics that you want to work on?

  • Samba+Windows: Allow multiple connections by different users?

    Hello there, I have a machine running Ubuntu with Samba that I use to share stuff with my family's Windows machines in our local network. Currently they access a share for movies/music/etc with one user. I want to connect them to another share as a different user (for example, user "goytacaz"). When I try connecting to this new share, Windows gives me "Error 1219" and complains about multiple connections by the same user. How do I get my machine to accept multiple connections by the same user?
