  • What does the 'X' in .aspx, docx, xlsx, etc... represent?

    - by Serapth
    It's one of those things you just take for granted until one day someone asks you and you realize you can't answer it. Much like for years I never questioned the use of 1033 directories in Microsoft products for years until one day, someone asked me about it. Around the release of .NET and Office 2007, Microsoft added an x to basically all of their extensions and I frankly took it as representing XML, but that simply doesn't make sense with .aspx. So, I realize this is a very non technical question, but now that the question has been asked of me and my googling hasn't given me an answer, can anyone tell me with authority what the X represents? Is it extended? Xml? Or is there no meaning behind it?

  • lamp server permissions on development server

    - by user101289
    I run a LAMP server on a ubuntu laptop I use only for development. I am not greatly concerned with security, since the server is never accessible outside the local network, and it's turned off when I'm not using it. My question is what is the simplest and 'best' way to set permissions/users/groups so that when my myself user creates, edits or writes files in the webroot, I won't need to go through and CHMOD / CHOWN everything back to the www-data user? Should I add myself to the www-data group? Or chown the webroot to www-data:myself? Or is there a best practice for this situation so I don't have to keep re-setting the ownership of these files? Thanks

  • How to share my localhost over the internet?

    - by Loolooii
    I really want to share my localhost over the internet to show my friends the progress of the website we're working on, so that I don't need to upload it to the public server each time I make a change. showoff.io is not free and localtunnel gives me "failed to authenticate" when trying to upload my public key (a lot of people seem to have this problem and there doesn't seem to be a solution for this). Does anyone know any other free service I can use or any other solution at all? I'm using a Mac. Thanks. UPDATE: with localhost I mean a web server running on my computer, I have a dynamic IP address and no I'm not behind a router (just using a wireless modem).

  • How to stop processes from going into the page file

    - by Not a Name
    I have a server, and windows vista, 64-bit, 4gb ram. Sometimes the server randomly drops into the page file, and disconnects everyone who was online. Only after I click the cmd.exe window does it comes back out. How do I mark a program as not eligible for the page file? If this is relevant, I'm using a Minecraft server with the following command line arguments: java -server -Xmx256M -Xms256M -XX:+UseConcMarkSweepGC -XX:+DisableExplicitGC -XX:+UseAdaptiveGCBoundary -XX:MaxGCPauseMillis=200 -XX:-UseGCOverheadLimit -XX:SurvivorRatio=16 -Xnoclassgc -XX:UseSSE=3 -XX:ParallelGCThreads=3 -jar minecraft_server.jar nogui

  • Copy large files to multiple machines on a LAN

    - by Jonathan Callen
    I have a few large files that I need to copy from one Linux machine to about 20 other Linux machines, all on the same LAN as quickly as is feasible. What tools/methods would be best for copying these files, noting that this is not going to be a one-time copy. These machines will never be connected to the Internet, and security is not an issue. Update: The reason for my asking this is because (as I understand it) we are currently using scp in serial to copy the files to each of the machines and I have been informed that this is "too slow" and a faster alternative is being sought. According to what I have been told, attempting to parallelize the scp calls simply slows it down further due to hard drive seeks.

  • uTorrent error: Access is denied

    - by Ben Franchuk
    When I booted my computer today and opened up uTorrent it went on, as usual, to check the torrents that I had been running before. On one it returned an "Access is denied" error after it had been checked. I have absolutely no idea why this is happening as I was downloading the same torrent just the night before, and additionally because I have other torrents going in the same downloads folder and they do not have any such errors. It may be worth noting that on said defective torrent, there appear to be no seeds and no connected peers (of the 33 available) and three of the trackers appear to be inactive as well (those being Peer Exchange, Local Peer Discovery and DHT). I have rebooted a few times in an attempt to fix this problem, but to no success. I also tried a few times force rechecking / force starting but neither of those worked either. edit I booted today and it was working for whatever reason. thanks for all of the help anyways guys!

  • Mass deleting files in windows

    - by aaginor
    I have a directory, that contains ~ 3 million files in certain subdirectories on a Windows 2008 server. Manually deleting the files via SHIFT+DEL on the root dir takes ages. Is there any other way to do the deletion in a faster manner?

  • How can I automatically synchronize a directory tree on multiple machines?

    - by Blacklight Shining
    I have two Mac laptops and a Debian server, each with a directory that I would like to keep in sync between the three. The solution should meet the following criteria (in rough order of importance): It must not use any third-party service (e.g. Dropbox, SugarSync, Google whatever). This does not include installing additional software (as long as it's free). It must not require me to use specific directories or change my way of storing things. (Dropbox does this IIRC) It must work in all directions (changes made on /any/ machine should be pushed to the others) All data sent must be encrypted (I have ssh keypairs set up already) It must work even when not all machines are available (changes should be pushed to a machine when it comes back online) It must work even when the /directories/ on some machines are not available (they may be stored on disk images which will not always be mounted) This can be solved for Macs by using launchd to automatically launch and kill (or in some way change the behavior of) whatever daemon is used for syncing when the images are mounted and unmounted. It must be immediate (using an event-based system, not a periodic one like cron) It must be flexible (if more machines are added, I should be able to incorporate them easily) I also have some preferences that I would like to be fulfilled, but do not have to be: It should notify me somehow if there are conflicts or other errors. It should recognize symbolic and hard links and create corresponding ones. It should allow me to create a list of exceptions (subdirectories which will not be synced at all). It should not require me to set up port forwarding or otherwise reconfigure a network. This can be solved by using an ssh tunnel with reverse port forwarding. If you have a solution that meets some, but not all of the criteria, please contribute it in the comments as it might be useful in some way, and it might be possible to meet some of the criteria separately. What I tried, and why it didn't work: rsync and lsyncd do not support bidirectional synchronization csync2 is designed for server clusters and does not appear to work with machines with dynamic IPs DRBD (suggested by amotzg) involves installing a kernel module and does not appear to work on systems running OS X

  • How to disable or tune filesystem cache sharing for OpenVZ?

    - by gertvdijk
    For OpenVZ, an example of container-based virtualization, it seems that host and all guests are sharing the filesystem cache. This sounds paradoxical when talking about virtualization, but this is actually a feature of OpenVZ. It makes sense too. Because only one kernel is running, it's possible to benefit from sharing the same pages of filesystem cache in memory. And while it sounds beneficial, I think a set up here actually suffers in performance from it. Here's why I think why: my machines aren't actually sharing any files on disk so I can't benefit from this feature in OpenVZ. Several OpenVZ machines are running MySQL with MyISAM tables. MyISAM relies on the system's filesystem cache for caching of data files, unlike InnoDB's buffer pool. Also some virtual machines are known to do heavy and large I/O operations on the same filesystem in the host. For example, when running cat *.MYD > /dev/null on some large database in one machine, I saw the filesystem cache lowering in another, monitored by htop. This essentially flushes all the useful filesystem cache in guests (FIFO) and so it flushes the MySQL caches in the guests. Now users are complaining that MySQL is very slow. And it is. Some simple SELECT queries take several seconds on times disk I/O is heavily used by other machines. So, simply put: Is there a way to avoid filesystem cache being wiped out by other virtual machines in container-based virtualization? Some thoughts: Choosing algorithm for flushing filesystem cache in the kernel. (possible? how?) Reserving a certain amount of pages for a single VM. (seems no option for filesystem cache type of pages that reading man vzctl) Will running MySQL on another filesystem get me anywhere? If not, I think my alternatives are: Use KVM for MySQL-MyISAM running VMs. KVM actually assigns memory to the VM and does not allow swapping out caches unless using a balloon driver. Move to InnoDB and tune the buffer pools, dirty pages, etc. This is now considered to be 'nice to have' on the long-term as not everyone responsible for administration of the system understands InnoDB. more suggestions welcome. System software: Proxmox (now 1.9, could be upgraded to 2.x). One big LV assigned for the VMs.

  • How to remove directories from source after copying them?

    - by user55542
    I just want to move dirs. I looked successively at mv, cp and rsync, since each tool in turn didn't seem to have the option to remove directories from source after copying them. For instance, mv needs files, not dirs, when src and dst are on different devices: "inter-device move failed: src to dst; unable to remove target: Is a directory" Perhaps the simplest way to do this is by using an additional deletion cmd, although I'd prefer not to use it, since that increases risk of data loss.

  • avoiding console window display when scheduled task runs batch file

    - by cherouvim
    I have a small batch file which xcopies some files from one folder to another which I've scheduled (via windows scheduled tasks) to run every 1 hour: @echo off xcopy c:\foo c:\bar /E /C /F /Y Since this is my workstation, I'm most probably doing work when the task executes, and then the black dos console window is displayed (lasts 2-3 seconds) and steals window focus. I don't wish to see the files copied and of course the batch file does not ask for any user input. Is there a way to avoid displaying the console completely?

  • How can I organize movies, with IMDB import and fields for tags?

    - by fluxtendu
    How can I organize movies on Windows? Features wanted: IMDB import fields: director, genre, year, actors,... covers manage DVD / BD / ripped AVIs, MKV moving/renaming files according fields I want to achieve something like: M:\Movies\Director\year. title (genre).avi A syntax that lets me choose how I organize my files (like foobar2000 & mp3 files) according IMDB and personal tags would be great. Auto fetch covers and listing of not-yet-ripped/yet-to-be-seen/wanted/loaned movies (txt, HTML or whatever) would be some nice features too.

  • What can prevent a Server 2008 machine accessing its OWN UNC shares?

    - by Simon
    I need to set up a UNC share for my hosted dedicated server to access a share on itself. Unfortunately TFS requires a UNC share. I am on a Windows Server 2008 Standard SP2 64bit dedicated server behind a PIX 501 firewall hosted with GoDaddy. I just cannot get the server to access itself and get this error: Windows cannot access \\SERVER\SHARE Check the spelling of the name.. etc. I've found numerous questions about this but no answer to my problem. Server 2008 Standard x64 SP2 Workgroup - not domain Windows Firewall is off Computer browser service is on I am trying to access \\MYMACHINE\TFS-BUILDS by typing in - or double clicking. Neither works. Machine has single network card Filesharing wizard says share was ok Share was showing under 'Computer management' Permissions are set to 'everyone' full control No obvious errors in eventlog Reboot didn't fix it Unfortunately I cannot try to access other shares in or out of this machine because it is a hosted dedicated server and the only machine behind a hardware firewall. The only thing left i can think of is that the hardware firewall needs to be configured. I don't think it is this because we have a 2003 Server machine behind a different hardware firewall and that one works fine. What on earth is left?!
