  • How to write files in specific order?

    - by Bernie
    Okay, here's a weird problem -- My wife just bought a 2014 Nissan Altima. So, I took her iTunes library and converted the .m4a files to .mp3, since the car audio system only supports .mp3 and .wma. So far so good. Then I copied the files to a DOS FAT-32 formatted USB thumb drive, and connected the drive to the car's USB port, only to find all of the tracks were out of sequence. All tracks begin with a two digit numeric prefix, i.e., 01, 02, 03, etc. So you would think they would be in order. So I called Nissan Connect support and the rep told me that there is a known problem with reading files in the correct order. He said the files are read in the same order they are written. So, I manually copied a few albums with the tracks in a predetermined order, and sure enough he was correct. So I copied about 6 albums for testing, then changed to the top level directory and did a "find . music.txt". Then I passed this file to rsync like this: rsync -av --files-from=music.txt . ../Marys\ Music\ Sequenced/ The files looked like they were copied in order, but when I listed the files in order of modified time, they were in the same sequence as the original files: ../Marys Music Sequenced/Air Supply/Air Supply Greatest Hits ls -1rt 01 Lost In Love.mp3 04 Every Woman In The World.mp3 03 Chances.mp3 02 All Out Of Love.mp3 06 Here I Am (Just When I Thought I Was Over You).mp3 05 The One That You Love.mp3 08 I Want To Give It All.mp3 07 Sweet Dreams.mp3 11 Young Love.mp3 So the question is, how can I copy files listed in a file named music.txt, and copy them to a destination, and ensure the modification times are in the same sequence as the files are listed?

  • rename files with the same name

    - by snorpey
    Hi. I use the following function to rename thumbnails. For example, if I upload a file called "image.png" to an upload folder, and this folder already has a file named "image.png" in it, the new file automatically gets renamed to "image-copy-1.png". If there also is a file called "image-copy-1.png" it gets renamed to "image-copy-2.png" and so on. The following function returns the new filename. At least that's what it is supposed to do... The renaming doesn't seeem to work correctly, though. Sometimes it produces strange results, like: 1.png 1-copy-1.png 1-copy-2.png 1-copy-2-copy-1.png 1-copy-2-copy-3.png I hope you understand my problem, despite my description being somewhat complex... Can you tell me what went wrong here? (bonus question: Is regular expressions the right tool for doing this kind of stuff?) <?php function renameDuplicates($path, $file) { $fileName = pathinfo($path . $file, PATHINFO_FILENAME); $fileExtension = "." . pathinfo($path . $file, PATHINFO_EXTENSION); if(file_exists($path . $file)) { $fileCopy = $fileName . "-copy-1"; if(file_exists($path . $fileCopy . $fileExtension)) { if ($contains = preg_match_all ("/.*?(copy)(-)(\\d+)/is", $fileCopy, $matches)) { $copyIndex = $matches[3][0]; $fileName = substr($fileCopy, 0, -(strlen("-copy-" . $copyIndex))) . "-copy-" . ($copyIndex + 1); } } else { $fileName .= "-copy-1"; } } $returnValue = $fileName . $fileExtension; return $returnValue; }?>

  • Novocaine - How to loop file playback? (iOS)

    - by lppier
    I'm using Novocaine by alexbw Novocaine for my audio project. I'm playing around with the example code here for file reading. The file plays back with no problem. I would like to loop this recording with the gap between the loops - any suggestion as to how I can do so? Thanks. Pier. // AUDIO FILE READING OHHH YEAHHHH // ======================================== NSArray *pathComponents = [NSArray arrayWithObjects: [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject], @"testrecording.wav", nil]; NSURL *inputFileURL = [NSURL fileURLWithPathComponents:pathComponents]; NSLog(@"URL: %@", inputFileURL); fileReader = [[AudioFileReader alloc] initWithAudioFileURL:inputFileURL samplingRate:audioManager.samplingRate numChannels:audioManager.numOutputChannels]; [fileReader play]; [fileReader setCurrentTime:0.0]; //float duration = fileReader.getDuration; [audioManager setOutputBlock:^(float *data, UInt32 numFrames, UInt32 numChannels) { [fileReader retrieveFreshAudio:data numFrames:numFrames numChannels:numChannels]; NSLog(@"Time: %f", [fileReader getCurrentTime]); }];

  • SSIS Catalog, Windows updates and deployment failures due to System.Core mismatch

    - by jamiet
    This is a heads-up for anyone doing development on SSIS. On my current project where we are implementing a SQL Server Integration Services (SSIS) 2012 solution we recently encountered a situation where we were unable to deploy any of our projects even though we had successfully deployed in the past. Any attempt to use the deployment wizard resulted in this error dialog: The text of the error (for all you search engine crawlers out there) was: A .NET Framework error occurred during execution of user-defined routine or aggregate "create_key_information": System.IO.FileLoadException: Could not load file or assembly 'System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) ---> System.IO.FileLoadException: The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040) System.IO.FileLoadException: System.IO.FileLoadException:     at Microsoft.SqlServer.IntegrationServices.Server.Security.CryptoGraphy.CreateSymmetricKey(String algorithm)    at Microsoft.SqlServer.IntegrationServices.Server.Security.CryptoGraphy.CreateKeyInformation(SqlString algorithmName, SqlBytes& key, SqlBytes& IV) . (Microsoft SQL Server, Error: 6522) After some investigation and a bit of back and forth with some very helpful members of the SSIS product team (hey Matt, Wee Hyong) it transpired that this was due to a .Net Framework fix that had been delivered via Windows Update. I took a look at the server update history and indeed there have been some recently applied .Net Framework updates: This fix had (in the words of Matt Masson) “somehow caused a mismatch on System.Core for SQLCLR” and, as you may know, SQLCLR is used heavily within the SSIS Catalog. The fix was pretty simple – restart SQL Server. This causes the assemblies to be upgraded automatically. If you are using Data Quality Services (DQS) you may have experienced similar problems which are documented at Upgrade SQLCLR Assemblies After .NET Framework Update. I am hoping the SSIS team will follow-up with a more thorough explanation on their blog soon. You DBAs out there may be questioning why Windows Update is set to automatically apply updates on our production servers. We’re checking that out with our hosting provider right now You have been warned! @Jamiet

  • Best Solution for Load Balancing NFS File Access?

    - by DairyKnight
    I'm trying to find an optimum solution for accessing the NFS file share in my company. We have a central file server in North America and has 30GB~50GB of updated data everyday. And it's very slow for our Europe and Asia branches to access directly. Therefore, I'm trying to setup two replicate servers in those continents. I'm currently using rsync, but wonder if there exists a better solution acts more like a distributed RAID, which allows the user to transparently access the file whether synced or not. And user request will be dispatched to remote server if the file is not yet synced. I'm now looking into DRBD, but it seems not to have the functionality of auto-dispatching requests. Does anyone know if there's a better solution?

  • Puppet file transfer slow

    - by Noodles
    I have a puppet master and slaves in different datacenters. The latency between them is ~40ms. When I run "puppet agent --test" on a slave to apply the latest manifest it takes ~360 seconds to finish. After doing some digging I can see the main cause of the slow down is file transfers. It seems it's taking ~10 seconds to transfer each file. The files are only small (configuration files) so I can't understand why they would take so long. This is an example of a file in my manifest: file { "/etc/rsyncd.conf" : owner => "root", group => "root", mode => 644, source => "puppet:///files/rsyncd/rsyncd.conf" } Running puppet-profiler I see this: 10.21s - File[/etc/rsyncd.conf] It also seems I cannot update more than one server at once using puppet. If I run two servers at the same time then puppet takes twice as long. I have changed the puppet master from using webrick to mongrel, but this doesn't seem to help. This is making deploying changes painful. A simple config change can take an hour to roll out to all servers.

  • Corrupt file indicative of corrupt hard drive?

    - by Elipsicon
    I have noticed that two files on my (almost full) 2 TB hard drive have been corrupted. One file has 20 kB (!) corrupted, i.e. consecutive 20 kB have changed, even though the modification date of the file hasn't changed and I haven't worked with this file for over a year. This tells me that something "below" the file system level has messed with the data and the only thing I can think of is hardware failure, most likely hard disk failure. I've tested my RAM already and it works flawlessly. I'm using ext4 on Linux, if that is of any help. Is this normal? Is it time to change my hard drive disk before something worse happens? What can I do to prevent that from happening in the future? Is there some built-in feature of, or extension to ext4 that includes additional error correcting code and/or watches files for changes that haven't been caused by the OS?

  • Windows File System Analysis

    - by bouvierr
    I am looking for a FREE tool to perform analyses on the NTFS file system of my Windows 7 PC. I want to easily see the amount of data distributed throught out the entire file system. The following applications seem very good, but they are not free and probably overkill for my requirements: FolderSizes 5 MailMeter Windows File System Reporting Tool I am aware that some applications (like Folder Size 2.5) can add a column in Windows Explorer to show the size of each folder, but I am looking for something more like a reporting tool. Thank you for your suggestions.

  • OSX: Selecting default application for all unknown and different file types (extensions)

    - by Leo
    I work in cluster computing and am using Mac OS X 10.6. I send off hundreds of computing jobs a day, and each one comes back with with a different extension. For example, svmGeneSelect.o12345 which is the std output of my svmGeneSelect job which is job number 12345. I don't control the extensions. All files are plain text. I want OSX to open any file extension that it hasn't seen before with my favorite text editor when I click on it. Or even better set up file association defaults for extension patterns ie textEdit for extensions matching *.o*. I do NOT want to create file associations for individual files since this extension will only ever exist once, and I do not want to go through the process of selecting the application to use for each file. Thanks for any help you can offer.

  • Difference between sh file.sh and file.sh

    - by RAS
    I have two questions : What is the difference between executing sh filename.sh and filename.sh? How can I make both of them giving me the same output ? I'm asking this question as right now I'm facing a problem. I'm trying to run a Java + SWT application from terminal. When I do filename.sh, it gives me the desired output. But when I do sh filename.sh or bash filename.sh, it throws me an error : Exception in thread "main" java.lang.NoClassDefFoundError: MainForm/java Caused by: java.lang.ClassNotFoundException: MainForm.java at java.net.URLClassLoader$1.run(URLClassLoader.java:202) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) Could not find the main class: MainForm.java. Program will exit. I know this question is already asked here but I'm still not clear about it. I have gone through the following links : What is the difference between ./ and sh to run a script? Can scripts run even when they are not set as executable? Can anyone help me with this?
