  • Read ahead buffering while playing video file from optical disc

    - by Saxtus
    I was wondering if there is a program for Windows 7 (64-bit), that reads ahead the file to be played back (usually MKV files in my case) to the RAM, so the disc that the video file resides in, won't spin for the entire duration of the playback, but only every time the cache is almost empty (with big enough cache so it won't need the drive for long periods). A program that I've used in the past (called DVDIdle), was doing that universally for every video player I wanted, but they've stopped updating it 6 years ago and now it doesn't seem to work with Windows 7 (tried using compatibility mode too). The method I am using now, is to either have the drive wearing down and buzzing all the time or manually copy the entire file to HDD, SSD or RamDisk and play it from there. The closest thing I've found, is a software that slows down the drive's spin speed, but I was looking for something more convenient, automated, without waiting for an entire file to be copied before starting playback or needing any HDD space, like I've used to in the past. Thanks in advance.

  • Using awk to split text file every 10,000 lines

    - by Sneaky Wombat
    I have a large gzip'd text file. I'd like to something like: zcat BIGFILE.GZ | awk (snag 10,000 lines and redirect to...)|gzip -9 smallerPartFile.gz the awk part up there, I basically want it to take 10,000 lines and send it to gzip and then repeat until all lines in the original input file are consumed. I found a script that claims to do this, but when I run it on my files and then diff the original to the ones that were split and then merged, lines are missing. So, something is wrong with the awk part and I'm not sure what part is broken. Here's the code. Can someone tell me why this doesn't yield a file that can be split and merged and then diff'd to the original successfully? # Generate files part0.dat.gz, part1.dat.gz, etc. # restore with: zcat foo* | gzip -9 > restoredFoo.sql.gz (or something like that) prefix="foo" count=0 suffix=".sql" lines=10000 # Split every 10000 line. zcat /home/foo/foo.sql.gz | while true; do partname=${prefix}${count}${suffix} # Use awk to read the required number of lines from the input stream. awk -v lines=${lines} 'NR <= lines {print} NR == lines {exit}' >${partname} if [[ -s ${partname} ]]; then # Compress this part file. gzip -9 ${partname} (( ++count )) else # Last file generated is empty, delete it. rm -f ${partname} break fi done

  • rsync : Read input from a file and sync accordingly

    - by Dheeraj
    I have a text file which contains the list of files and directories that I want to copy (one on a line). Now I want rsync to take this input from my text file and sync it to the destination that I provide. I've tried playing around with "--include-from=FILE" and "--file-from=FILE" options of rsync but is is just not working I also tried pre-fixing "+" on each line in my file but still it is not working. I have tried coming with various filter PATTERNs as outlined in the rsync man page but it is not working. Could someone provide me correct syntax for this use case. I've tried above things on Fedora 15, RHEL 6.2 and Ubuntu 10.04 and none worked. So i am definitely missing something. Many thanks.

  • Can't delete ntuser.dat file to remove profiles after reboot

    - by Matrix Mole
    I've ran into an issue where some servers will not release the handle on the ntuser.dat file even after a reboot. Or quite possible, after the reboot, the ntuser.dat file is getting re-loaded into memory. The user accounts are definitely not being accessed (some of them belong to users that have not been with the company in over a year). It seems to be on Windows 2003 servers, but I can't be 100% certain that there aren't some 2000 servers showing this issue as well. When I try to use process explorer or handle.exe from sysinternals to kill the handle on these ntuser.dat files, the handle remains open and connected. Handle.exe even reports that the handle was broken while it remains in use. I've even taken ownership on the file and tried to kill the handle to no effect (windows shows I have ownership of the file, but still refuses to release the handle). I have looked into the registry to see if I can discover where the files may be getting loaded at. Unfortunately, the username is appearing in too many places for me to be certain which one is actually loading their reg file into memory. Any suggestions on how I can either break the handle on the files, or prevent them from getting re-loaded after a reboot?

  • Discrepancy in file size on disk and ls output

    - by smokinguns
    I have a script that checks for gzipped file sizes greater than 1MB and outputs files along with their sizes as a report. This is the code: myReport=`ls -ltrh "$somePath" | egrep '\.gz$' | awk '{print $9,"=>",$5}'` # Count files that exceed 1MB oversizeFiles=`find "$somePath" -maxdepth 1 -size +1M -iname "*.gz" -print0 | xargs -0 ls -lh | wc -l` if [ $oversizeFiles -eq 0 ];then status="PASS" else status="CHECK FAILED. FOUND FILES GREATER THAN 1MB" fi echo -e $status"\n"$myReport The problem is that ls command outputs the files sizes as 1.0MB in the report but the status is "FAIL" as "$oversizeFiles" variable's value is 2. I checked the file sizes on disk and 2 files are 1.1MB. Why this discrepancy? How should I modify the script so that I can generate an accurate report? BTW, I'm on a Mac. Here is what man page for "find" says on my Mac OSX: -size n[ckMGTP] True if the file's size, rounded up, in 512-byte blocks is n. If n is followed by a c,then the primary is true if the file's size is n bytes (characters). Similarly if n is followed by a scale indicator then the file's size is compared to n scaled as: k kilobytes (1024 bytes) M megabytes (1024 kilobytes) G gigabytes (1024 megabytes) T terabytes (1024 gigabytes) P petabytes (1024 terabytes)

  • SQL Server 2008 R2 Writing To Text File

    - by zzzzzzzzzzzzzzzzzzzzzzzzzzzzzz
    I used to write to text files from SQL Server using the code listed below: DECLARE @FS INT --File System Object DECLARE @OLEResult INT --Result message/code DECLARE @FileID INT --Pointer to file --Create file system object (OLE Object) EXECUTE @OLEResult = sp_OACreate 'Scripting.FileSystemObject', @FS OUT IF @OLEResult <> 0 PRINT 'Scripting.FileSystemObject.Failed' -----OPEN FILE----- EXECUTE @OLEResult = sp_OAMethod @FS, 'OpenTextFile', @FileID OUT, @FileName, 8, 1 IF @OLEResult <> 0 PRINT 'OpenTextFile.Failed' It appears this is no longer supported in sql server 2008 r2.

  • pcfg_openfile: unable to check htaccess file, ensure it is readable

    - by rxt
    After moving a website folder on my local development machine to another drive, then moving it back, I got a 403 error. Most of this problem had probably to do with rights that got messed up. After deleting the code and restoring it from SVN, the rights seemed allright. The error stayed however. The setup is a bit complex, as follows: I have Ubuntu 10.4 as development machine, trying to mimic the server as much as possible We use Eclipse + SVN and I create all projects in a local folder under my user account In /var/www-vhosts I create folders for each vhost, like this one: test.localhost test.local/index.php: includes the index file of the project test.local/.htaccess is a dynamic link to the htaccess file in a project subfolder I get the following error in the apache error log: [Thu Jul 08 15:55:56 2010] [crit] [client 127.0.0.1] (13)Permission denied: /var/www-vhosts/test.localhost/.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable The problem seems to be the .htaccess file, or the link to it. When I empty the htaccess, nothing changes When I remove the link, the index-include produces some output (in the apache error log) When I remove the link and replace it with the actual file, I get another error: [Thu Jul 08 16:47:54 2010] [error] [client 127.0.0.1] Symbolic link not allowed or link target not accessible: /var/www-vhosts/test.localhost/test I'm lost here, don't know what to do next. Do you have any ideas what I can try? This setup has worked before, but I don't know what is different now.

  • How to convert an Outlook 2007 .ost file to a .pst file, so I can open it in another, local computer?

    - by ysap
    I have a couple of backed up .pst and .ost files that were used with a server that is not accessible anymore. On my local machine, I was able to Add... the .pst file to my fresh Outlook 2007 and access the emails. However, adding an .ost file does not seem to be an options in the Accounts Settings dialog. Is it possible to import the .ost file, or convert it to a .pst w/o the aid of the exchange server?

  • nginx: js file loads indifferently every refresh

    - by poymode
    I have this nginx problem wherein a js file in a rails app loads indifferently. Whenever I try to access the JS file in the browser and refresh the page, the scrollbar changes length meaning sometimes it loads half the js page, sometimes the whole and sometimes just a part of it. the js file size is 71K. my nginx server is on different server,separate from my rails app. when I try to access the js file directly through the app server, lets say 10.48.30.150:3000/javascripts/file.js it works fine and doesnt show any half-loaded page. but when I use the nginx server which upstreams the rails app, it shows the indifferent page loads. here is my nginx http conf error_log /usr/local/nginx/logs/error.log; pid /usr/local/nginx/logs/nginx.pid; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; server_names_hash_bucket_size 256; access_log /usr/local/nginx/logs/access.log; sendfile on; #tcp_nopush on; keepalive_timeout 0; tcp_nodelay on; #gzip on; #gzip_min_length 4096; #gzip_buffers 16 8k; #gzip_types application/x-javascript text/css text/plain; large_client_header_buffers 4 8k; client_max_body_size 2G; include /usr/local/nginx/conf.d/*.conf; }

  • Upload large database SQL file

    - by Devy
    I've a database of more than 20Gb of size on my hard disk. What is the best way to upload it with the least (money) load possible on the server? - I'm on Windows 7. - I have FTP and SSH access on the server. I avoid using FTP because my connection cuts off a lot, I can't imagine I re-upload again the file after failing on 99%. I found some tools that split the large .sql file to small .sql files, but they didn't mention how to gather these files again into one file. Another way is to archive the big .sql file to .rar with -v option, upload them through FTP then unpack them. But unpacking will also cost, right? I know it will cost in any cases, but any best practice will be strongly appreciated.

  • windows printer spool gets stuck with file at 64kb from linux and mac

    - by Juan Diego
    Hi I have two printers one on a file server with windows 2003, and other with windows XP. The thing is that when i try to print from my machine, my file stays in queue for ever, it says 64kb out of whatever the file i send. I have seen similar problems with some machines that run on Mac OS X. The windows machines apparently have no problems printing. They are not connect through active directory, just the network. In the past I have seen people install non microsoft windows Printer server on windows, i dont remember the name of any of the programs. I have being googling a lot and have not found anything to replace the microsoft print spooler service, maybe i am mistaken. Everyday I have to restart the print spooler service i even created a bat file for it. I am out of ideas here.

    I have installed Apache server. Two clients ex client_1 and client_2. The operation that we are performing on client_1 reflecting to client_2. We have etc/hosts file in our software install location which is keep on changing for client_2 with client_1 IP address.

Please explain the use of hosts file and where and when it will change by Apache service. The hosts file in the location /etc/hosts/ for the both clients are same ============================================= Do not remove the following line, or various programs that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost Local LAN 190.0.0.1 client_1.Example.com client_1 190.0.0.2 client_2.Example.com client_2 HR LAN 10.1.74.2 client_1hr peer 10.1.74.3 client_2hr ESP LAN 10.69.69.1 client_1esp 10.69.69.2 client_2esp Any help will be appreciated.

  • User account that is not allowed to edit one file on Ubuntu

    - by spacemonkey
    Hi, I wanted to ask if it is possible to create a user account on Ubuntu so that it had all powers and rights of root account except it would be impossible to edit a certain file. What I intend to do is to edit host file in order to block access of certain websites, and then create a user account which would be the same as root account except it would be not able to edit host file. Maybe there is an easier way to block an access of certain sites forever? Thanks!

  • Encrypting a single File with password and keyfile

    - by Ctroy
    I am a fan of True Crypt and I guess it's the best encryption tool available. As far as I understand, True Crypt created encrypted containers which acts a place to store files. But I would like to encrypt a single file. Preferably with a password and a special key file (like in truecrypt). It would be great (but not mandatory), if the file doesn't require any third party software to encrypt and decrypt, in the sense that I provide the password and key to the file directly. Thanks in advance.

  • Big Excel File Freezing/Running Slowly

    - by ktm5124
    Hi, My co-worker has a very large Excel file (over 7 MB) that suffers from the problems of (A) running slowly (B) taking forever to open/save/close and (C) freezing the computer, requiring a restart. I set the calculations to Manual, and I repaired the file, but the file didn't change in file size and it is still having these problems. My questions are: (1) Is there any way around this problem or is Excel just bad at handling ~7MB files? (2) Would upgrading RAM make a big difference? (3) It's possible that we can't afford to spend the money on a RAM upgrade. Are there are any other ways of mitigating the problem? Thanks.

  • Large scale file replication with an option to "unsubscribe" from a replicated file on a given machine

    - by Alexander Gladysh
    I have a 100+ GB files per day incoming on one machine. (File size is arbitrary and can be adjusted as needed.) I have several other machines that do some work on these files. I need to reliably deliver each incoming file to the worker machines. A worker machine should be able to free its HDD from a file once it is done working with it. It is preferable that a file would be uploaded to the worker only once and then processed in place, and then deleted, without copying somewhere else — to minimize already high HDD load. (Worker itself requires quite a bit of bandwidth.) Please advise a solution that is not based on Java. None of existing replication solutions that I've seen can do the "free HDD from the file once processed" stuff — but maybe I'm missing something... A preferable solution should work with files (from the POV of our business logic code), not require the business logic to connect to some queue or other. (Internally the solution may use whatever technology it needs to — except Java.)

  • Accidental Extract Location - How to Clean Up?

    - by Gordon
    Sometimes I will do a command such as unzip tons_of_files.zip And I will forget to put a -d to point to a subdirectory. This causes the current folder to get filled with tons of files that are intermixed with the existing files. What is the best way to remove all these new files and/or move them to a new directory? I want to avoid having to manually examine the directory and determine if the file was part of the archive or was already present.

  • Write once, read many (WORM) using Linux file system

    - by phil_ayres
    I have a requirement to write files to a Linux file system that can not be subsequently overwritten, appended to, updated in any way, or deleted. Not by a sudo-er, root, or anybody. I am attempting to meet the requirements of the financial services regulations for recordkeeping, FINRA 17A-4, which basically requires that electronic documents are written to WORM (write once, read many) devices. I would very much like to avoid having to use DVDs or expensive EMC Centera devices. Is there a Linux file system, or can SELinux support the requirement for files to be made complete immutable immediately (or at least soon) after write? Or is anybody aware of a way I could enforce this on an existing file system using Linux permissions, etc? I understand that I can set readonly permissions, and the immutable attribute. But of course I expect that a root user would be able to unset those. I considered storing data to small volumes that are unmounted and then remounted read-only, but then I think that root could still unmount and remount as writable again. I'm looking for any smart ideas, and worst case scenario I'm willing to do a little coding to 'enhance' an existing file system to provide this. Assuming there is a file system that is a good starting point. And put in place a carefully configured Linux server to act as this type of network storage device, doing nothing else. After all of that, encryption on the files would be useful too!

  • Windows 7. Permission to search but not for any user to browse

    - by acidzombie24
    I recently changed permissions on my external usb drive so users by default dont have read permission. Now i realize i cannot search through the drive. after setting 'everyone' permission to read i could again. How do i set it so everyone does not have read permission except for my username (i hate clicking yes to admin prompt everytime i move a file) and allow the system to search the drive when users are allowed to access those files?
