• Jmeter- HTTP Cache Manager, Unable to cache everything what it is being cached by Browser

  - by chinmay brahma

  I used HTTP Chache Manager to Cache files which are being cached in browser. I am successful of doing it for some of the pages. Number of files being cached in Jmeter is equal to Number of files being cached by browser. But in some cases : I found number files being cached is lesser than the files being cached by browser. Using Jmeter I found only 5 files are being cached but in real browser 12 files are getting cached. Thanks in advance

• Use ASP.NET 4 Browser Definitions with ASP.NET 3.5

  - by Stephen Walther

  We updated the browser definitions files included with ASP.NET 4 to include information on recent browsers and devices such as Google Chrome and the iPhone. You can use these browser definition files with earlier versions of ASP.NET such as ASP.NET 3.5. The updated browser definition files, and instructions for installing them, can be found here: http://aspnet.codeplex.com/releases/view/41420 The changes in the browser definition files can cause backwards compatibility issues when you upgrade an ASP.NET 3.5 web application to ASP.NET 4. If you encounter compatibility issues, you can install the old browser definition files in your ASP.NET 4 application. The old browser definition files are included in the download file referenced above. What’s New in the ASP.NET 4 Browser Definition Files The complete set of browsers supported by the new ASP.NET 4 browser definition files is represented by the following figure:     If you look carefully at the figure, you’ll notice that we added browser definitions for several types of recent browsers such as Internet Explorer 8, Firefox 3.5, Google Chrome, Opera 10, and Safari 4. Furthermore, notice that we now include browser definitions for several of the most popular mobile devices: BlackBerry, IPhone, IPod, and Windows Mobile (IEMobile). The mobile devices appear in the figure with a purple background color. To improve performance, we removed a whole lot of outdated browser definitions for old cell phones and mobile devices. We also cleaned up the information contained in the browser files. Here are some of the browser features that you can detect: Are you a mobile device? <%=Request.Browser.IsMobileDevice %> Are you an IPhone? <%=Request.Browser.MobileDeviceModel == "IPhone" %> What version of JavaScript do you support? <%=Request.Browser["javascriptversion"] %> What layout engine do you use? <%=Request.Browser["layoutEngine"] %>   Here’s what you would get if you displayed the value of these properties using Internet Explorer 8: Here’s what you get when you use Google Chrome: Testing Browser Settings When working with browser definition files, it is useful to have some way to test the capability information returned when you request a page with different browsers. You can use the following method to return the HttpBrowserCapabilities the corresponds to a particular user agent string and set of browser headers: public HttpBrowserCapabilities GetBrowserCapabilities(string userAgent, NameValueCollection headers) { HttpBrowserCapabilities browserCaps = new HttpBrowserCapabilities(); Hashtable hashtable = new Hashtable(180, StringComparer.OrdinalIgnoreCase); hashtable[string.Empty] = userAgent; // The actual method uses client target browserCaps.Capabilities = hashtable; var capsFactory = new System.Web.Configuration.BrowserCapabilitiesFactory(); capsFactory.ConfigureBrowserCapabilities(headers, browserCaps); capsFactory.ConfigureCustomCapabilities(headers, browserCaps); return browserCaps; } At the end of this blog entry, there is a link to download a simple Visual Studio 2008 project – named Browser Definition Test -- that uses this method to display capability information for arbitrary user agent strings. For example, if you enter the user agent string for an iPhone then you get the results in the following figure: The Browser Definition Test application enables you to submit a user-agent string and display a table of browser capabilities information. The browser definition files contain sample user-agent strings for each browser definition. I got the iPhone user-agent string from the comments in the iphone.browser file. Enumerating Browser Definitions Someone asked in the comments whether or not there is a way to enumerate all of the browser definitions. You can do this if you ware willing to use a little reflection and read a private property. The browser definition files in the config\browsers folder get parsed into a class named BrowserCapabilitesFactory. After you run the aspnet_regbrowsers tool, you can see the source for this class in the config\browser folder by opening a file named BrowserCapsFactory.cs. The BrowserCapabilitiesFactoryBase class has a protected property named BrowserElements that represents a Hashtable of all of the browser definitions. Here's how you can read this protected property and display the ID for all of the browser definitions: var propInfo = typeof(BrowserCapabilitiesFactory).GetProperty("BrowserElements", BindingFlags.NonPublic | BindingFlags.Instance); Hashtable browserDefinitions = (Hashtable)propInfo.GetValue(new BrowserCapabilitiesFactory(), null); foreach (var key in browserDefinitions.Keys) { Response.Write("" + key); } If you run this code using Visual Studio 2008 then you get the following results: You get a huge number of outdated browsers and devices. In all, 449 browser definitions are listed. If you run this code using Visual Studio 2010 then you get the following results: In the case of Visual Studio 2010, all the old browsers and devices have been removed and you get only 19 browser definitions. Conclusion The updated browser definition files included in ASP.NET 4 provide more accurate information for recent browsers and devices. If you would like to test the new browser definitions with different user-agent strings then I recommend that you download the Browser Definition Test project: Browser Definition Test Project

• Trace File Source Adapter

  The Trace File Source adapter is a useful addition to your SSIS toolbox.  It allows you to read 2005 and 2008 profiler traces stored as .trc files and read them into the Data Flow.  From there you can perform filtering and analysis using the power of SSIS. There is no need for a SQL Server connection this just uses the trace file. Example Usages Cache warming for SQL Server Analysis Services Reading the flight recorder Find out the longest running queries on a server Analyze statements for CPU, memory by user or some other criteria you choose Properties The Trace File Source adapter has two properties, both of which combine to control the source trace file that is read at runtime. SQL Server 2005 and SQL Server 2008 trace files are supported for both the Database Engine (SQL Server) and Analysis Services. The properties are managed by the Editor form or can be set directly from the Properties Grid in Visual Studio. Property Type Description AccessMode Enumeration This property determines how the Filename property is interpreted. The values available are: DirectInput Variable Filename String This property holds the path for trace file to load (*.trc). The value is either a full path, or the name of a variable which contains the full path to the trace file, depending on the AccessMode property. Trace Column Definition Hopefully the majority of you can skip this section entirely, but if you encounter some problems processing a trace file this may explain it and allow you to fix the problem. The component is built upon the trace management API provided by Microsoft. Unfortunately API methods that expose the schema of a trace file have known issues and are unreliable, put simply the data often differs from what was specified. To overcome these limitations the component uses  some simple XML files. These files enable the trace column data types and sizing attributes to be overridden. For example SQL Server Profiler or TMO generated structures define EventClass as an integer, but the real value is a string. TraceDataColumnsSQL.xml  - SQL Server Database Engine Trace Columns TraceDataColumnsAS.xml    - SQL Server Analysis Services Trace Columns The files can be found in the %ProgramFiles%\Microsoft SQL Server\100\DTS\PipelineComponents folder, e.g. "C:\Program Files\Microsoft SQL Server\100\DTS\PipelineComponents\TraceDataColumnsSQL.xml" "C:\Program Files\Microsoft SQL Server\100\DTS\PipelineComponents\TraceDataColumnsAS.xml" If at runtime the component encounters a type conversion or sizing error it is most likely due to a discrepancy between the column definition as reported by the API and the actual value encountered. Whilst most common issues have already been fixed through these files we have implemented specific exception traps to direct you to the files to enable you to fix any further issues due to different usage or data scenarios that we have not tested. An example error that you can fix through these files is shown below. Buffer exception writing value to column 'Column Name'. The string value is 999 characters in length, the column is only 111. Columns can be overridden by the TraceDataColumns XML files in "C:\Program Files\Microsoft SQL Server\100\DTS\PipelineComponents\TraceDataColumnsAS.xml". Installation The component is provided as an MSI file which you can download and run to install it. This simply places the files on disk in the correct locations and also installs the assemblies in the Global Assembly Cache as per Microsoft’s recommendations. You may need to restart the SQL Server Integration Services service, as this caches information about what components are installed, as well as restarting any open instances of Business Intelligence Development Studio (BIDS) / Visual Studio that you may be using to build your SSIS packages. Finally you will have to add the transformation to the Visual Studio toolbox manually. Right-click the toolbox, and select Choose Items.... Select the SSIS Data Flow Items tab, and then check the Trace File Source transformation in the Choose Toolbox Items window. This process has been described in detail in the related FAQ entry for How do I install a task or transform component? We recommend you follow best practice and apply the current Microsoft SQL Server Service pack to your SQL Server servers and workstations. Please note that the Microsoft Trace classes used in the component are not supported on 64-bit platforms. To use the Trace File Source on a 64-bit host you need to ensure you have the 32-bit (x86) tools available, and the way you execute your package is setup to use them, please see the help topic 64-bit Considerations for Integration Services for more details.

• How to edit files directly on webdav in windows.

  - by phazei

  I have a webDAV setup with the cPanel webdisk. I can connect to it through NetHood and I can drag and drop files to/from there. What I can't do is simply edit any of the files directly. I need to copy it somewhere else, edit it, then copy it back. That's essentially what is needed with ftp, though smart clients will monitor the file, making it easier than webDAV in the current state I'm using it in. I was under the impression that webdav was supposed to let me work on the files as if it were a local drive. But nothing can actually open the files. How can I go about bringing more functionality around to it? Or is this as good as it gets? I have tried 'net use q:\ https://myserver.com:2083' and 'net use q:\ '\myserver.com@SSL:2083\' but neither work and only throws: "System error 67 has occurred. The network name cannot be found." I ultimately want to use TortiseSVN with the webDAV so I can have my working copy running on the server.

  Hi all, This is a bit unorthodox but I'm trying to figure out if there's a way to access files stored in the src tree of my applications apk in Android. I'm trying to use i-Jetty (Jetty implementation for Android) and rather than use it as a separate application and manually download my war file, I'd rather just bake i-jetty in. However, in order to use (easily) standard html/jsp I need to be able to give it a document root, preferably within my application's apk file. I know Android specifically works to prevent you from accessing (freely) the stuff on the actual system so this may not be possible, but I'm thinking it might be possible to access something within the apk. One option to work around this would be to have all of the files stored in the res directory and then copy them to the sdcard on startup but this wouldn't allow me to automatically remove the files on uninstall. To give you an idea of what I've tried, currently, the html files are stored in org.webtext.android Context rootContext = new Context(server_, "/", Context.SESSIONS); rootContext.setResourceBase("org/webtext/webapp"); Returns a 404 error. final URL url = this.getClassLoader().getResource("org/webtext/webapp"); Context html = new WebAppContext(url.toExternalForm(), "/"); Blows up with a NullPointerException because no URL is returned from the getResource call. Any thoughts would be greatly appreciated! Thanks, Chris

• Making ANTLR generated class files into one jar file.

  - by prosseek

  With ANTLR, I get some java class files after compilation. And I need to make all the class files into one jar file. I make manifest.mf file that has one line "Main-class: Test" to indicate the main file. I run 'jar cmf manifest.mf hello.jar *.class' to get hello.jar file. But when I try to run 'java -jar hello.jar', I get the following error messages. $ java -jar hello.jar Exception in thread "main" java.lang.NoClassDefFoundError: Test Caused by: java.lang.ClassNotFoundException: Test at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:315) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:330) at java.lang.ClassLoader.loadClass(ClassLoader.java:250) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:398) What's wrong? I get correct result when I run 'java Test'. The example that I used is the source code from the book 'The Definitive ANTLR Reference' that you can download from http://www.pragprog.com/titles/tpantlr/source_code The example is in /tour/trees/. I get a bunch of class files after compiling g and java files.

• Is there an XML XQuery interface to existing XML files?

  - by xsaero00

  My company is in education industry and we use XML to store course content. We also store some course related information (mostly metainfo) in relational database. Right now we are in the process of switching from our proprietary XML Schema to DocBook 5. Along with the switch we want to move course related information from database to XML files. The reason for this is to have all course data in one place and to put it under Subversion. However, we would like to keep flexibility of the relational database and be able to easily extract specific information about a course from an XML document. XQuery seems to be up to the task so I was researching databases that supports it but so far could not find what I needed. What I basically want, is to have my XML files in a certain directory structure and then on top of this I would like to have a system that would index my files and let me select anything out of any file using XQuery. This way I can have "my cake and eat it too": I will have XQuery interface and still keep my files in plain text and versioned. Is there anything out there at least remotely resembling to what I want? If you think that what I an asking for is nonsense please make an alternative suggestion. On the related note: What XML Databases (preferably native and open source) do you have experience with and what would you recommend?

• Why can't I include these data files in a Python distribution using distutils?

  - by froadie

  I'm writing a setup.py file for a Python project so that I can distribute it. The aim is to eventually create a .egg file, but I'm trying to get it to work first with distutils and a regular .zip. This is an eclipse pydev project and my file structure is something like this: ProjectName src somePackage module1.py module2.py ... config propsFile1.ini propsFile2.ini propsFile3.ini setup.py Here's my setup.py code so far: from distutils.core import setup setup(name='ProjectName', version='1.0', packages=['somePackage'], data_files = [('config', ['..\config\propsFile1.ini', '..\config\propsFile2.ini', '..\config\propsFile3.ini'])] ) When I run this (with sdist as a command line parameter), a .zip file gets generated with all the python files - but the config files are not included. I thought that this code: data_files = [('config', ['..\config\propsFile1.ini', '..\config\propsFile2.ini', '..\config\propsFile3.ini'])] indicates that those 3 specified config files should be copied to a "config" directory in the zip distribution. Why is this code not accomplishing anything? What am I doing wrong? (I have also tried playing around with the paths of the config files... But nothing seems to help. Would Python throw an error or warning if the path was incorrect / file was not found?)

• Is there something like a Filestorage class to store files in?

  - by nebukadnezzar

  Is there something like a class that might be used to store Files and directories in, just like the way Zip files might be used? Since I haven't found any "real" class to write Zip files (real class as in real class), It would be nice to be able to store Files and Directories in a container-like file. A perfect API would probably look like this: int main() { ContainerFile cntf("myContainer.cnt", ContainerFile::CREATE); cntf.addFile("data/some-interesting-stuff.txt"); cntf.addDirectory("data/foo/"); cntf.addDirectory("data/bar/", ContainerFile::RECURSIVE); cntf.close(); } ... I hope you get the Idea. Important Requirements are: The Library must be crossplatform anything *GPL is not acceptable in this case (MIT and BSD License are) I already played with the thought of creating an Implentation based on SQLite (and its ability to store binary blobs). Unfortunately, it seems impossible to store Directory structures in a SQLite Database, which makes it pretty much useless in this case. Is it useless to hope for such a class library?

• How do I tell nant to only call csc when there are cs files in to compile?

  - by rob_g

  In my NAnt script I have a compile target that calls csc. Currently it fails because no inputs are specified: <target name="compile"> <csc target="library" output="${umbraco.bin.dir}\Mammoth.${project::get-name()}.dll"> <sources> <include name="project/*.cs" /> </sources> <references> </references> </csc> </target> How do I tell NAnt to not execute the csc task if there are no CS files? I read about the 'if' attribute but am unsure what expression to use with it, as ${file::exists('*.cs')} does not work. The build script is a template for Umbraco (a CMS) projects and may or may not ever have .cs source files in the project. Ideally I would like to not have developers need to remember to modify the NAnt script to include the compile task when .cs files are added to the project (or exclude it when all .cs files are removed).

• how to filter files from the root "classes" and "test-classes" folders in Eclipse?

  - by Kidburla

  I am using ClearCase in my application which generates a whole load of ".copyarea.db" files (one in every folder). These cause conflicts when publishing to Tomcat as Eclipse will bundle the "classes" and "test-classes" folders into one JAR (not sure why it does this - as there is no need to have test classes available on the application server). Any folders with the same names will have a separate .copyarea.db in the classes and test-classes branches. I managed to get around this problem in general by adding ".copyarea.db" to the Filtered resources on the Java->Compiler->Building->Output Folder preference page. This stops the file appearing in source output (package/class folders), the vast majority of cases. However there remains the problem of the root folder, i.e. "target/classes/.copyarea.db" and "target/test-classes/.copyarea.db". These files are not filtered as they are not part of the compile task. Just deleting the files manually doesn't help either, as Eclipse expects to find them and doesn't. How can I exclude these ".copyarea.db" files from the root "classes" and "test-classes" folders?

• VC++ 6 and MS Speech SDK 5.1 fatal error C1083: Cannot open source file: 'files\microsoft': No such

  - by eg123

  Trying to compile an application (flite synthesis sapi) on vc++6. This requires Microsoft Speech SDK 5.1 Have included C:\Program Files\Microsoft Speech SDK 5.1\IDL C:\Program Files\Microsoft Speech SDK 5.1\include using Toolsoptionsdirectories and also on another attempt via ProjectSettings Repeatedly get this error microsoft fatal error C1083: Cannot open source file: 'files\microsoft': No such file or directory speech fatal error C1083: Cannot open source file: 'speech': No such file or directory sdk fatal error C1083: Cannot open source file: 'sdk': No such file or directory idl fatal error C1083: Cannot open source file: '5.1\idl': No such file or directory FliteCMUKalDiphone.idl Thought it may be spaces related so included full path in quotes in relevant .h files. No joy Installed Microsoft Speech SDK 5.1 on another machine in same folder as flite and renamed to mssdk51 (so no spaces in pathname) but same error came up. Tried pasting in contents of each .idl called in file where glitch seems to generate Still same message. I am new to C++ and programming in general. My only guess is that something in the speech sdk is calling the .idl file and I can't find where from. Of course this is probably way wrong!

• Is it possible to install into Program Files with limited privileges?

  - by Marek

  I have an application that will be deployed as MSI package (authored in WiX). I am deciding whether to specify elevated or limited privileges as required for the installer. The application does not include anything requiring elevated privileges besides the default install location, which is under Program Files. Now the problem: If I specify elevated privileges, then the user is prompted by UAC for administrator password during the installation. This is not required and prevents non-admin users from installing. If I specify limited privileges, then the user is presented with a dialog to select install location with Program Files being default. In case they do not change the install location (95 % of end users probably won't), then the installer will fail with a message that they should contact the Administrator or run the application as administrator. If they launch the installer as Administrator then they can install into Program Files without problem - but most of the users won't probably know how to launch an installer as administrator. I can potentially set the default install location to e.g. C:\Company name\Program\, but this seems nonstandard to me and majority of users will not probably like this (they are probably used to installing into Program Files). How do you solve this problem with installing applications under limited user accounts?

• Multiple XML/XSLT files in PHP, transform one with XSLT and add others but process it first with PHP

  - by ipalaus

  I am processing XML files transformations with XSLT in PHP correctly. Actually I use this code: $xml = new DOMDocument; $xml->LoadXML($xml_contents); $xsl = new DOMDocument; $xsl->load($xsl_file); $proc = new XSLTProcesoor; $proc->importStyleSheet($xsl); echo $proc->transformToXml($xml); $xml_contents is the XML processed with PHP, this is done by including the XML file first and then assigning $xml_contents = ob_get_contents(); ob_end_clean();. This forces to process the PHP code on the XML, and it works perfectly. My problem is that I use more than one XML file and this XML files has PHP code on it that need to be processed AND have a XSLT file associated to process the data. Actually I'm including this files in XSLT with the next code: <!-- First I add the XML file --> <xsl:param name="menu" select="document('menu.xml')" /> <!-- Next I add the transformations for menu.xml file --> <xsl:include href="menu.xsl" /> <!-- Finally, I process it on the actual ("parent") XML --> <xsl:apply-templates select="$menu/menu" /> My questiion is how I can handle this. I need to add mutiple XML(+XSLT) files to my first XML file that will containt PHP so it needs to be processed. Thank you in advance!

• How would I sort files to directories based on filenames?

  - by gnomed

  I have a huge number of files to sort all named in some terrible convention. Here are some examples: (4)_mr__mcloughlin____.txt 12__sir_john_farr____.txt (b)mr__chope____.txt dame_elaine_kellett-bowman____.txt dr__blackburn______.txt These names are supposed to be a different person (speaker) each. Someone in another IT department produced these from a ton of XML files using some script but the naming is unfathomably stupid as you can see. I need to sort literally tens of thousands of these files with multiple files of text for each person; each with something stupid making the filename different, be it more underscores or some random number. They need to be sorted by speaker. This would be easier with a script to do most of the work then I could just go back and merge folders that should be under the same name or whatever. There are a number of ways I was thinking about doing this. parse the names from each file and sort them into folders for each unique name. get a list of all the unique names from the filenames, then look through this simplified list of unique names for similar ones and ask me whether they are the same, and once it has determined this it will sort them all accordingly. I plan on using Perl, but I can try a new language if it's worth it. I'm not sure how to go about reading in each filename in a directory one at a time into a string for parsing into an actual name. I'm not completely sure how to parse with regex in perl either, but that might be googleable. For the sorting, I was just gonna use the shell command: `cp filename.txt /example/destination/filename.txt` but just cause that's all I know so it's easiest. I dont even have a pseudocode idea of what im going to do either so if someone knows the best sequence of actions, im all ears. I guess I am looking for a lot of help, I am open to any suggestions. Many many many thanks to anyone who can help. B.

• What is a good layout for a somewhat advanced home network and storage solution?

  - by Shaun

  My home network/storage needs are changing and I am searching for some opinions and starting points on what a good network/storage layout would be that can serve my needs for a few years into the future. I think I have a decent starting point for equipment, but I am also willing to invest fairly heavily in a solution that can last me for a while. I am a bit of a tech nerd and I have a moderate tolerance for setup of the solution. I would prefer if maintenance of the system is somewhat low once it is setup, but I am willing to accept some tradeoffs. Existing equipment: Router - Netgear WNDR3700 (gigabit) Router - DLink Gamerlounge DGL-4300 (gigabit) Switch - 16 port Trendnet green switch (gigabit) Switch - 5 port Trendnet green (gigabit) Computer - i7-950 office computer (gigabit ethernet) Computer - Q6600 quad core media center, hooked up to TV, records shows (gigabit ethernet) Computer - Acer 1810T ultraportable laptop (gigabit and N ethernet) NAS - Intel SS4200-E (gigabit) External hard drive - 2TB WD Green drive (esata) All kinds of miscellaneous network connected TV, Bluray, Verizon network extender, HDhomerun TV tuners, etc. Requirements: -Robust backup solution for a growing collection of huge family picture files and personal files, around 1.5TB. (Including offsite backup) -Central location for all user's files, while also keeping them secure from each other. -Storage for terabytes of movie backups and recorded TV, and access to them from all computers (maybe around 4TB eventually) -Possibility to host files to friends and family easily Nice to have: -Backup of terabytes of movie backups Intriguing possibilities: -Capability to have users' Windows desktops and files look the same from all network computers I am not sure if the new Windows Home Server 2011 would fit into this well, if I need a domain server, how best to organize my backups, or how to most effectively use RAID. Currently I am simply backing up all computers to a RAID 1 on the NAS box, which I was thinking could prevent a situation where I reach for a backup and find that the disk is corrupt. One possibility that I am thinking about now is simply using my media center PC with a huge RAID of hard drives on which all files are stored. Pseudo-backup of all files would be present because of the RAID, but important files would also be backed up off site via carrying hard drives to work. But what if corruption seeps into the files and the corrupted data is then backed up? Does RAID protect against this? I really want to take next to zero risks with the irreplaceable files. I can handle some degree of risk with the movies and other files. I'm looking for critiques on this idea as well as other possibilities. To summarize, my goal is high functionality, media capable, and robust backup of irreplaceable files.

• Data loss through permissions change?

  - by charliehorse55

  I seem to have deleted some files on my media drive, simply by changing the permissions. The Story I have many operating systems installed on my computer, and constantly switch between them. I bought a 1TB HD and formatted it as HFS+ (not journaled). It worked well between OSX and all of my linux installations while having much better metadata support than NTFS. I never synced the UIDs for my operating systems so the permissions were always doing funny things. Yesterday I tried to fix the permissions by first changing the UIDs of the other operating systems to match OSX, and then changing the file ownership of all files on the drive to match OSX. About 50% of the files on the drive were originally owned by OSX, the other half were owned by the various linux installations. I started to try and change the file permissions for the folders, and that's when it went south. The Commands These commands were run recursively on the one section of the drive. sudo chflags nouchg sudo chflags -N sudo chown myusername sudo chmod 666 sudo chgrp staff The Bad Sometime during the execution of these commands, all of the files belonging to OSX were deleted. If a folder had linux based files it would remain intact but any folder containing exclusively OSX files was erased. If a folder containing linux files also contained a subfolder with only OSX files, the sub folder would remain but is inaccesible and displays a file size of 0 bytes. Luckily these commands were only run on the videos folder, I also have a music folder with the same issue but I did not execute any of these commands on it. Effectively I have examples of the file permissions for all 3 states - the linux files before and after, and the OSX files before. OSX File Before -rw-r--r--@ 1 charliehorse 1000 3634241 15 Nov 2008 /path/to/file com.apple.FinderInfo 32 Linux File before: -rw-r--r--@ 1 charliehorse 1000 5321776 20 Sep 2002 /path/to/file/ com.apple.FinderInfo 32 Linux File After (Read only): (Different file, but I believe the same permissions originally) -rw-rw-rw-@ 1 charliehorse staff 366982610 17 Jun 2008 /path/to/file com.apple.FinderInfo 32 These files still exist so if there are any other commands to run on them to determine what has happened here, I can do that. EDIT Running ls on one of the "empty" deleted OSX folders yields this: ls: .: Permission denied ls: ..: Permission denied ls: subdirA: Permission denied ls: subdirB: Permission denied ls: subdirC: Permission denied ls: subdirD: Permission denied I believe my files might still be there, but the permissions are screwed.

• How to transfer files and settings from Windows 7 x64 to Windows 2008 R2?

  - by Mohamed Meligy

  If I want to re-install Windows 7 Enterprise 64 bit (or any other edition of Windows 7), I'd typically use "Windows Easy Transfer" utility built in the OS to backup and restore my files and settings. But in my case, I'm migrating to Windows Server 2008 R2. If I remember well -having worked on both Windows 2008/2008R2 before- "Windows Easy Transfer" is NOT installed on Windows server, and it doesn't even understand the format of the backup file it generates (".MIG" file). I can't remember for sure whether this is true, is it? And if it's true, what is the alternative for transferring the files and more importantly program settings to Windows 2008 R2? Of course I'm aware of the "manual" option and that automatic transfer sure will not transfer everything. Options??

• Converting encoding of multiple files with iconv (Mac OS)?

  - by Ilya Birman

  I need to convert a whole bunch of files from Windows-1251 to UTF-8. After doing 10 of them by hand in BBEdit, I got bored ;-) I found out that there is an iconv CL tool. I tried this: iconv -f WINDOWS-1251 -t UTF-8 inputfile However it seems that iconv just outputs the converted text instead of writing it to file. Also, there is no outputfile parameter for it. How do I write the changes back to original files? Thanks. Edit: Please note, that inputfile value is actually *.txt, so the solution has to work with that.

• How to prevent any files from being copied onto the Desktop?

  - by Kaushik Gopal

  Gentlepeeps, Is there any solution to prevent copying of files onto the desktop? My folks and i currently have one super-common-comp in our place. And when all of the laptops are busy, we tend to do some quick surfing on this comp. I prefer to keep things freakishly organized in this comp and one thing i hate is having those off-shoot irritating forwarded downloads on my desktop. Is there some way to restrict files from being copied onto the desktop? I tried making the administrator user's desktop folder as read-only :P . That doesn't solve the problem. Any other ideas/software/solutions? cheers.

• How to run sed on over 10 million files in a directory?

  - by Sandro

  I have a directory that has 10144911 files in it. So far I've tried the following: for f in ls; do sed -i -e 's/blah/blee/g' $f; done Crashed my shell, the ls is in a tilda but i can't figure out how to make one. ls | xargs -0 sed -i -e 's/blah/blee/g' Too many args for sed find . -name "*.txt" -exec sed -i -e 's/blah/blee/g' {} \; Couldn't fork any more no more memory Any other ideas on how to create this kind command? The files don't need to communicate with each other. ls | wc -l seems to work (very slow) so it must be possible.
