• RubyGems installation errors when using 'sudo' or not

  - by Kenny Peng

  I have a machine that is running Ubuntu Hardy, which provides its own RubyGems package. Unfortunately that version of RubyGems (1.1.1) is too old to do anything useful with, so I decided to manually update RubyGems to the current version (1.3.6). That part went smoothly, and if I do gem -v, I get 1.3.6 which is expected. The problem is when I try to do: sudo gem install rack, it returns this error: ERROR: While executing gem ... (Errno::EACCES) Permission denied - /home/username/.gem Usually when I install gems as root, it knows to install it into /usr/lib/ruby/gems, so why is it checking my home directory at all? Another quirk is when I do gem install rack (not as root), it says: ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions into the /usr/lib/ruby/gems/1.8 directory. which is where I want it to go. I've already tried clearing source_caches, trying different versions of RubyGems (1.3.5), forcing installation into /usr/lib with -i to no avail. Any ideas on why RubyGems is so insistent on checking my /home directory when installing as root?

• Proper way to set PYTHONPATH (including precedence)

  - by Wells

  In .bashrc I have: export PYTHONPATH=/home/wells/py-mlb I've verified this is actually being set. so, in this directory is another directory called 'py_mlb'- the actual module. So I go python -v and then import py_mlb but it does: >>> import py_mlb import py_mlb # directory /usr/local/lib/python2.6/dist-packages/py_mlb Then I do import sys and print sys.path and I see: >>> print sys.path ['', '/usr/local/lib/python2.6/dist-packages/python_memcached-1.44-py2.6.egg', '/usr/local/lib/python2.6/dist-packages/pymc-2.1alpha-py2.6-linux-i686.egg', '/usr/local/lib/python2.6/dist-packages/nose-0.11.1-py2.6.egg', '/home/wells/py-mlb', '/usr/lib/python2.6', '/usr/lib/python2.6/plat-linux2', '/usr/lib/python2.6/lib-tk', '/usr/lib/python2.6/lib-old', '/usr/lib/python2.6/lib-dynload', '/usr/lib/python2.6/dist-packages', '/usr/local/lib/python2.6/dev-packages', '/usr/lib/pymodules/python2.6', '/usr/lib/pymodules/python2.6/gtk-2.0', '/usr/local/lib/python2.6/dist-packages'] So my path from .bashrc IS in there, and from the look of it it's even before dist-packages but it's importing the module from dist-packages. How can I finagle this so the PYTHONPATH as defined by .bashrc takes precedence? Thanks!

• Managing common components with Fossil CVS

  - by Larry Lustig

  I'm a Fossil (and CVS configuration novice) attempting to create and manage a set of distributed Fossil repositories for a Delphi project. I have the following directory tree: Projects Some Project Delphi Components LookupListView Some Client Some Project For Client Some Other Project For Client Source Code Project Resources Project Database I am setting up Fossil version control in order to version and share Projects\Some Client\Some Other Project For Client\Source Code, which contains Delphi 2010 source for a database project. This project makes use of Projects\Delphi Components\LookupListView which is a Delphi component. I need this code to be included in the versioning system for my project. I will, in theory, need to include it in other Fossil repositories in the future, as well. If I create my Fossil repository at the Source Code or Some Other Project For Client level, I cannot add any code above that level to my repository. What is the proper way to deal with this? The two solutions that occur to me are 1) Creating a separate repository for LookupListView and make sure that everyone who uses a repository for a project that references it "knows" that they must also get the current version of this project as well. This seems to defeat the purpose of being able to obtain a complete, current version of the project with a single checkout. The problem is magnified because there are other common component dependencies in this project. 2) Establishing my Fossil repository in the Projects directory, so I can check in files from various subfolders. This seems to me to involve an awful lot of extra path-typing when doing adds, and also to impose my directory structure (Some Client\Some Other Project For Client\Source) on the other users of the repository -- in this case, the actual client. Any suggestions appreciated.

• Apache rewrite rules redux

  - by AlexanderJohannesen

  I've got a REST framework that when plopped into any directory should Just Work(TM), and it seems to work fine when I've got projects in subdirectories, but not if it's in root. So, given a few example directories; / /project1 /bingo/project2 /hoopla/doopla/minor/project3 All of these works fine, except I'm getting "funnies"* when the project runs in the root directory (bit hard to explain, I suppose, but the second level rewrites are not working properly). Here's my attempt at a generic .htaccess file: RewriteEngine On RewriteRule ^static/ - [L] RewriteCond %{REQUEST_URI} ^$ RewriteRule .* ./ [R,L] RewriteRule ^index.php - [L] RewriteRule (.*) index.php?q=$1 [QSA,PT] (And yes, all projects have a subdirectory ./static which is ignored by rewrites) What I'm trying to achieve is a set of rewrite rules that work for most cases (which is, again, plonking the project in a directory the webserver serves). I'm not a rewrite rules wiz by a long shot, and any good advice and gotchas would be appreciated (and yes, I've gone through too many introductory articles. I need some serious juice.) More info on the funnies; my webserver has docroot in one spot (under /usr/share/apache2/default-site/), but a set of rules that says that /projects is pulled in from somewhere else that's not a subdirectory of docroot (/home/user/Projects/). When I go there, I get a list of /projects subdirectories, and if one of those subdirectories gets called (restmapp) with the proposed rewrite rules, I get ; The requested URL /home/user/Projects/restmapp/index.php was not found on this server.

• Publishing my Website to my Local Disk Causes Exceptions to show Paths including my Local Disk

  - by coffeeaddict

  I've published my website many times. But didn't think about this though until I came across this issue. So I decided to publish my WAP project to a local folder on my C drive first. Then used FTP to upload it to my shared host on discountasp.net. I noticed during runtime that the stack trace was referencing that local folder still and erroring out. Anyone know what config settings are affected when publishing? Obviously something is still pointing to my local C drive and I've searched my entire solution and don't see why. Here's the runtime error I get when my code tries to run in discountasp.net's web server Cannot write into the public directory - check permissions Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: ScrewTurn.Wiki.PluginFramework.InvalidConfigurationException: Cannot write into the public directory - check permissions Source Error: An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

• No test coverage files generated for Unit Test bundle in Xcode

  - by John Gallagher

  The Problem I've got a Cocoa project on the desktop and I'm using Xcode 3.2.1 on Snow Leopard 10.6.2. I want to generate code coverage files for my Unit Test Target in Xcode. What I've Tried As articles like this one suggest, I've adjusted the build settings to: “Generate Test Coverage Files” checked “Instrument Program Flow” checked “-lgcov” added to “Other Linker Flags” I've also set the Run Script section of the test target to have the following: # Run the unit tests in this test bundle. "${SYSTEM_DEVELOPER_DIR}/Tools/RunUnitTests" # Run gcov on the framework getting tested if [ "${CONFIGURATION}" = 'Coverage' ]; then FRAMEWORK_NAME=LapsusInterpretationEngine FRAMEWORK_OBJ_DIR=${OBJROOT}/${FRAMEWORK_NAME}.build/${CONFIGURATION}/EngineTests.build/Objects-normal/${NATIVE_ARCH} mkdir -p coverage pushd coverage find ${OBJROOT} -name *.gcda -exec gcov -o ${FRAMEWORK_OBJ_DIR} {} \; popd fi Since my Framework name is LapsusInterpretationEngine but my target is named EngineTests, I put this directly into the FRAMEWORK_OBJ_DIR but this didn't seem to help. I've tried cleaning before building. I've made sure all the above build settings apply to both the Unit Test Target and the Application Target. What I Get No .gcda or .gcno files anywhere in the build directory I'm using. I point CoverStory to the Objects-normal directory in my builds folder and it complains that there's nothing there for it to read. I must be doing something really obvious wrong. Anyone any ideas? I have tried the "EngineTests.build" directory being ${FRAMEWORK_NAME} and this gives the same results.

• Best Practice for Uploading Many (2000+) Images to A Server

  - by bob

  Hello, I have a general question about this. When you have a gallery, sometimes people need to upload 1000's of images at once. Most likely, it would be done through a .zip file. What is the best way to go about uploading this sort of thing to a server. Many times, server have timeouts etc. that need to be accounted for. I am wondering what kinds of things should I be looking out for and what is the best way to handle a large amount of images being uploaded. I'm guessing that you would allow a user to upload a zip file (assuming the timeout does not effect you), and this zip file is uploaded to a specific directory, lets assume in this case a directory is created for each user in the system. You would then unzip the directory on the server and scan the user's folder for any directories containing .jpg or .png or .gif files (etc.) and then import them into a table accordingly. I'm guessing labeled by folder name. What kind of server side troubles could I run into? I'm aware that there may be many issues. Even general ideas would be could so I can then research further. Thanks! Also, I would be programming in Ruby on Rails but I think this question applies accross any language.

• .NET load assembly error metabase config

  - by peter

  Hi, Yesterday I found out that the mailroot directory had moved to a different location on the C drive. I don't know how this happened as no configs were changed, using IIS7 with IIS6 SMTP service on Windows 2008 R2 web edition. I wanted to restore it to the default c:\inetpub\mailroot location. So I opened system32/inetsrv/MetaBase.xml, and in the node was the problem, BadMailDirectory, DropDirectory etc were all pointing to the wrong location... I changed them back to the default c:\inetpub\mailroot. Later I discovered an ASP.NET application was throwing this error: An error occurred in the Microsoft .NET Framework while trying to load assembly id 1. The server may be running out of resources, or the assembly may not be trusted with PERMISSION_SET = EXTERNAL_ACCESS or UNSAFE. Run the query again, or check documentation to see how to solve the assembly trust issues. For more information about this error: System.IO.FileNotFoundException: Could not load file or assembly 'microsoft.sqlserver.types, Version=10.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The system cannot find the file specified. I figured it had to do with my changes to the mailroot locations, so I gave ASP.NET access to the mailroot directory and it was working.... My question is, how is this possible? Why does APS.NET require access to the mailroot directory to load assemblies? Thanks

• Exclude string from wildcard in bash

  - by Peter O'Doherty

  Hi, I'm trying to adapt a bash script from "Sams' Teach Yourself Linux in 24 Hours" which is a safe delete command called rmv. The files are removed by calling rmv -d file1 file2 etc. In the original script a max of 4 files can by removed using the variables $1 $2 $3 $4. I want to extend this to an unlimited number of files by using a wildcard. So I do: for i in $* do mv $i $HOME/.trash done The files are deleted okay but the option -d of the command rmv -d is also treated as an argument and bash objects that it cannot be found. Is there a better way to do this? Thanks, Peter #!/bin/bash # rmv - a safe delete program # uses a trash directory under your home directory mkdir $HOME/.trash 2>/dev/null # four internal script variables are defined cmdlnopts=false delete=false empty=false list=false # uses getopts command to look at command line for any options while getopts "dehl" cmdlnopts; do case "$cmdlnopts" in d ) /bin/echo "deleting: \c" $2 $3 $4 $5 ; delete=true ;; e ) /bin/echo "emptying the trash..." ; empty=true ;; h ) /bin/echo "safe file delete v1.0" /bin/echo "rmv -d[elete] -e[mpty] -h[elp] -l[ist] file1-4" ;; l ) /bin/echo "your .trash directory contains:" ; list=true ;; esac done if [ $delete = true ] then for i in $* do mv $i $HOME/.trash done /bin/echo "rmv finished." fi if [ $empty = true ] then /bin/echo "empty the trash? \c" read answer case "$answer" in y) rm -i $HOME/.trash/* ;; n) /bin/echo "trashcan delete aborted." ;; esac fi if [ $list = true ] then ls -l $HOME/.trash fi

• Installing Mercurial on Mac OS X 10.6 Snow Leopard

  - by Matthew Rankin

  Installing Mercurial on Mac OS X 10.6 Snow Leopard I installed Mercurial 1.3.1 on Mac OS X 10.6 Snow Leopard from source using the following: cd ~/src curl -O http://mercurial.selenic.com/release/mercurial-1.3.1.tar.gz tar xzvf mercurial-1.3.1.tar.gz cd mercurial-1.3.1 make ALL sudo make install This installs the site-packages files for Mercurial in /usr/local/lib/python2.6/site-packages/. I know that installing Mercurial from the Mac Disk Image will install the files into /Library/Python/2.6/site-packages/, which is the site-packages directory for the Mac OS X default Python install. I have Python 2.6.2+ installed as a Framework with its site-packages directory in: /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages With Mercurial installed this way, I have to issue: PYTHONPATH=/usr/local/lib/python2.6/site-packages:"${PYTHONPATH}" in order to get Mercurial to work. Questions How can I install Mercurial from source with the site-packages in a different directory? Is there an advantage or disadvantage to having the site-packages in the current location? Would it be better in one of the Python site-package directories that already exist? Do I need to be concerned about virtualenv working correctly since I have modified PYTHONPATH (or any other conflicts for that matter)? Reasons for Installing from Source Dan Benjamin of Hivelogic provides the benefits of and instructions for installing Mercurial from source in his article Installing Mercurial on Snow Leopard.

• Missing line number in stack trace eventhough the PDB files are included

  - by Farzad

  This is running me nuts. I have this web service implemented w/ C# using VS 2008. I publish it on IIS. I have modified the release build so the pdb files are copied along with the dlls into the target directory on inetpub. Also web.config file has debug=true. Then I call a web service that throws an exception. The stack trace does not contain the line numbers. I have no idea what I am missing here, any ideas? Additional Info: If I run the web app using VS built-in web server, it works and I get line numbers in stack trace. But if I copy the same files (pdb and dll) that the VS built-in web server is using to IIS, still the line numbers are missing in stack trace. It seems that there is something related to the IIS that ignores the pdb files! Update When I publish to IIS, all the pdb files are published under the bin directory and everything looks fine. But when I go to "C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files" under the specific directory related to my project, I can see that the assembly (.dll) files are all there, but there is no pdb files. But this does not happen if I run the project using VS built-in web server. So if I copy the pdb files manually to the temp folder, I can see the line numbers. Any idea why the pdb files are not copied to the temp folder? BTW, when I attach to the worker process I can see that it says Symbols loaded!

• Unable to create website error (NEW)

  - by salvationishere

  I copied my ClickOnce deployment to my C:/Inetpub/ folder on my webserver and I deleted my Virtual directory. I deleted the WpfApplication1 folder beneath wwwroot in Win Explorer. Then I turned on Web Sharing for this folder. Then I viewed my IIS Manager and this new Share name appeared under wwwroot. So now under Inetpub folder on my web server I have the following directory path: C:\Inetpub\WpfApplication1\ with contents: Application Files publish.htm setup.exe WpfApplication1.application Next, I remapped both the publishing and installation URL's for the project to http://myserver/WpfApplication1/ And I clicked Publish Now. But after I performed a Publish Now operation, I got the following error on my development server (D610-M): Error 1 Failed to connect to 'http://myserver/WpfApplication1/' with the following error: Unable to create the Web site 'http://myserver/WpfApplication1/'. The Web server does not appear to have any authentication methods enabled. It asked for user authentication, but did not send a WWW-Authenticate header. 1 1 WpfApplication1 On my webserver, when I click Browse from the IIS Manager on the WpfApplication1 directory, it shows me the Install page. But after I click the Browse button, it returns an error which says: The remote name could not be resolved: 'd610-m' (D610-M is the name of my development server). How do I fix this?

• datanucleus enhancer & javaw: "the parameter is incorrect"

  I'm on windows XP using eclipse and the datanucleus enhancer for a gwt + gae app. When I run the enhancer, I get an error: Error Thu Oct 21 16:33:57 CDT 2010 Cannot run program "C:\Program Files\Java\jdk1.6.0_18\bin\javaw.exe" (in directory "C:\ag\dev"): CreateProcess error=87, The parameter is incorrect java.io.IOException: Cannot run program "C:\Program Files\Java\jdk1.6.0_18\bin\javaw.exe" (in directory "C:\ag\dev"): CreateProcess error=87, The parameter is incorrect at java.lang.ProcessBuilder.start(Unknown Source) at com.google.gdt.eclipse.core.ProcessUtilities.launchProcessAndActivateOnError(ProcessUtilities.java:213) at com.google.appengine.eclipse.core.orm.enhancement.EnhancerJob.runInWorkspace(EnhancerJob.java:154) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run(InternalWorkspaceJob.java:38) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) Caused by: java.io.IOException: CreateProcess error=87, The parameter is incorrect at java.lang.ProcessImpl.create(Native Method) at java.lang.ProcessImpl.<init>(Unknown Source) at java.lang.ProcessImpl.start(Unknown Source) ... 5 more I've had this problem before, and it was due to a long classpath.

The error message doesn't include any information about what directory it's in or anything. It's kind of infuriating! Is it possible to make the output of javaw more verbose? Is it possible to get around this class-path size bug?

• Installing Silverstripe on 000webhost.com (free web host)

  - by benwad

  Hi I'm trying to learn how to work Silverstripe so I extracted the tar file to my free hosting account. I then went on install.php and edited the permissions to meet the requirements set out in install.php but I still get two warnings from the 'webserver configuration' section: I can't tell what webserver you are running. Without Apache I can't tell if mod_rewrite is enabled. I can't tell whether mod_rewrite is running. You may need to configure a rewriting rule yourself. I looked in phpinfo() and mod_rewrite appears to be installed. I contacted the web host and they said it was to do with virtual directory paths, and I should add 'RewriteBase /' to the top of my .htaccess file in the public_html directory. However I did this and still had the same problem. The install.php script says that I can install it even with these warnings but when I press 'install' it just refreshes the install.php page. It doesn't even overwrite the .htaccess file. 000webhost.com says they have successfully installed Silverstripe on their user accounts without much configuration but I can't seem to find out how. EDIT: I managed to get to the next page but now there is another warning which is stopping it installing: Friendly URLs are not working. This is most likely because mod_rewrite isn't configuredcorrectly on your site. Please check the following things in your Apache configuration; you may need to get your web host or server administrator to do this for you: * mod_rewrite is enabled * AllowOverride All is set for your directory I also get this error message from the server: Warning: unlink(mysite/_config.php) [function.unlink]: Permission denied in /home/a2716553/public_html/install.php on line 701

• How do I implement repository pattern and unit of work when dealing with multiple data stores?

  - by Jason

  I have a unique situation where I am building a DDD based system that needs to access both Active Directory and a SQL database as persistence. Initially this wasnt a problem because our design was setup where we had a unit of work that looked like this: public interface IUnitOfWork { void BeginTransaction() void Commit() } and our repositories looked like this: public interface IRepository<T> { T GetByID() void Save(T entity) void Delete(T entity) } In this setup our load and save would handle the mapping between both data stores because we wrote it ourselves. The unit of work would handle transactions and would contain the Linq To SQL data context that the repositories would use for persistence. The active directory part was handled by a domain service implemented in infrastructure and consumed by the repositories in each Save() method. Save() was responsible with interacting with the data context to do all the database operations. Now we are trying to adapt it to entity framework and take advantage of POCO. Ideally we would not need the Save() method because the domain objects are being tracked by the object context and we would just need to add a Save() method on the unit of work to have the object context save the changes, and a way to register new objects with the context. The new proposed design looks more like this: public interface IUnitOfWork { void BeginTransaction() void Save() void Commit() } public interface IRepository<T> { T GetByID() void Add(T entity) void Delete(T entity) } This solves the data access problem with entity framework, but does not solve the problem with our active directory integration. Before, it was in the Save() method on the repository, but now it has no home. The unit of work knows nothing other than the entity framework data context. Where should this logic go? I argue this design only works if you only have one data store using entity framework. Any ideas how to best approach this issue? Where should I put this logic?

• File-level filesystem change notification in Mac OS X

  - by Paul J. Lucas

  I want my code to be notified when any file under (either directly or indirectly) a given directory is modified. By "modified", I mead I want my code to be notified whenever a file's contents are altered, it's renamed, or it's deleted; or if a new file is added. For my application, there can be thousands of files. I looked as FSEvents, but its Technology Overview says, in part: The important point to take away is that the granularity of notifications is at a directory level. It tells you only that something in the directory has changed, but does not tell you what changed. It also says: The file system events API is also not designed for finding out when a particular file changes. For such purposes, the kqueues mechanism is more appropriate. However, in order to use kqueue on a given file, one has to open the file to obtain a file descriptor. It's impractical to manage thousands of file descriptors (and would probably exceed the maximum allowable number of open file descriptors anyway). Curiously, under Windows, I can use the ReadDirectoryChangesW() function and it does precisely what I want. So how can one do what I want under Mac OS X? Or, asked another way: how would one go about writing the equivalent of ReadDirectoryChangesW() for Mac OS X in user-space (and do so very efficiently)?

• How to install DBD::mysql on OS X Server 10.6?

  - by Zoran Simic

  Trying to install DBD::mysql on OS X Server 10.6 (mac mini server). But I'm missing the mysql headers apparently. Since mysql is already part of OS X Server 10.6, I would like to NOT install anything else (no fink or darwin ports installs), just whatever's needed to get DBD::mysql installed and working. Do you know how I could do that? Do I have to install the headers somewhere? And if so, where? (again: I don't want to install another version of mysql on the box, want to use the version it came with). Is there a way to install DBD::mysql without compiling any C files? This is the error I get (the actual error is much longer, but these are the most meaningful bits, this is the first error reported). Checking if your kit is complete... Looks good Unrecognized argument in LIBS ignored: '-pipe' Note (probably harmless): No library found for -lmysqlclient Multiple copies of Driver.xst found in: /Library/Perl/5.10.0/darwin-thread-multi-2level/auto/DBI/ /System/Library/Perl/Extras/5.10.0/darwin-thread-multi-2level/auto/DBI/ at Makefile.PL line 907 Using DBI 1.611 (for perl 5.010000 on darwin-thread-multi-2level) installed in /Library/Perl/5.10.0/darwin-thread-multi-2level/auto/DBI/ Writing Makefile for DBD::mysql cp lib/DBD/mysql.pm blib/lib/DBD/mysql.pm cp lib/DBD/mysql/GetInfo.pm blib/lib/DBD/mysql/GetInfo.pm cp lib/DBD/mysql/INSTALL.pod blib/lib/DBD/mysql/INSTALL.pod cp lib/Bundle/DBD/mysql.pm blib/lib/Bundle/DBD/mysql.pm gcc-4.2 -c -I/Library/Perl/5.10.0/darwin-thread-multi-2level/auto/DBI -I/usr/include -fno-omit-frame-pointer -pipe -D_P1003_1B_VISIBLE -DSIGNAL_WITH_VIO_CLOSE -DSIGNALS_DONT_BREAK_READ -DIGNORE_SIGHUP_SIGQUIT -DDBD_MYSQL_INSERT_ID_IS_GOOD -g -arch x86_64 -arch i386 -arch ppc -g -pipe -fno-common -DPERL_DARWIN -fno-strict-aliasing -I/usr/local/include -Os -DVERSION=\"4.014\" -DXS_VERSION=\"4.014\" "-I/System/Library/Perl/5.10.0/darwin-thread-multi-2level/CORE" dbdimp.c In file included from dbdimp.c:20: dbdimp.h:22:49: error: mysql.h: No such file or directory dbdimp.h:23:45: error: mysqld_error.h: No such file or directory dbdimp.h:25:49: error: errmsg.h: No such file or directory

• Problem Linking Boost Filesystem Library in Microsoft Visual C++

  - by Scott

  Hello. I am having trouble getting my project to link to the Boost (version 1.37.0) Filesystem lib file in Microsoft Visual C++ 2008 Express Edition. The Filesystem library is not a header-only library. I have been following the Getting Started on Windows guide posted on the official boost web page. Here are the steps I have taken: I used bjam to build the complete set of lib files using: bjam --build-dir="C:\Program Files\boost\build-boost" --toolset=msvc --build-type=complete I copied the /libs directory (located in C:\Program Files\boost\build-boost\boost\bin.v2) to C:\Program Files\boost\boost_1_37_0\libs. In Visual C++, under Project Properties Additional Library Directories I added these paths: C:\Program Files\boost\boost_1_37_0\libs C:\Program Files\boost\boost_1_37_0\libs\filesystem\build\msvc-9.0express\debug\link-static\threading-multi I added the second one out of desperation. It is the exact directory where libboost_system-vc90-mt-gd-1_37.lib resides. In Configuration Properties C/C++ General Additional Include Directories I added the following path: C:\Program Files\boost\boost_1_37_0 Then, to put the icing on the cake, under Tools Options VC++ Directories Library files, I added the same directories mentioned in step 3. Despite all this, when I build my project I get the following error: fatal error LNK1104: cannot open file 'libboost_system-vc90-mt-gd-1_37.lib' Additionally, here is the code that I am attempting to compile as well as a screen shot of the aformentioned directory where the (assumedly correct) lib file resides: #include "boost/filesystem.hpp" // includes all needed Boost.Filesystem declarations #include <iostream> // for std::cout using boost::filesystem; // for ease of tutorial presentation; // a namespace alias is preferred practice in real code using namespace std; int main() { cout << "Hello, world!" << endl; return 0; } Can anyone help me out? Let me know if you need to know anything else. As always, thanks in advance.

• Node.js/ v8: How to make my own snapshot to accelerate startup

  - by Anand

  I have a node.js (v0.6.12) application that starts by evaluating a Javascript file, startup.js. It takes a long time to evaluate startup.js, and I'd like to 'bake it in' to a custom build of Node if possible. The v8 source directory distributed with Node, node/deps/v8/src, contains a SconScript that can almost be used to do this. On line 302, we have LIBRARY_FILES = ''' runtime.js v8natives.js array.js string.js uri.js math.js messages.js apinatives.js date.js regexp.js json.js liveedit-debugger.js mirror-debugger.js debug-debugger.js '''.split() Those javascript files are present in the same directory. Something in the build process apparently evaluates them, takes a snapshot of state, and saves it as a byte string in node/out/Release/obj/release/snapshot.cc (on Mac OS). Some customization of the startup snapshot is possible by altering the SconScript. For example, I can change the definition of the builtin Date.toString by altering date.js. I can even add new global variables by adding startup.js to the list of library files, with contents global.test = 1. However, I can't put just any javascript code in startup.js. If it contains Date.toString = 1;, an error results even though the code is valid at the node repl: Build failed: -> task failed (err #2): {task: libv8.a SConstruct -> libv8.a} make: *** [program] Error 1 And it obviously can't make use of code that depends on libraries Node adds to v8. global.underscore = require('underscore'); causes the same error. I'd ideally like a tool, customSnapshot, where customSnapshot startup.js evaluates startup.js with node and then dumps a snapshot to a file, snapshot.cc, which I can put into the node source directory. I can then build node and tell it not to rebuild the snapshot.

• Azure : The process cannot access the file "" because it is being used by another process.

  - by Shantanu

  Hi all, I am trying to get a matlab-compiled exe running on Azure cloud, and for that purpose need to get a v78.zip onto the local storage of the cloud and unzip it, before I can try to run an exe on the cloud. The program works fine when executed locally, but on deployment gives and error at line marked below in the code. The error is : The process cannot access the file 'C:\Resources\directory\cc0a20f5c1314f299ade4973ff1f4cad.WebRole.LocalStorage1\v78.zip' because it is being used by another process. Exception Details: System.IO.IOException: The process cannot access the file 'C:\Resources\directory\cc0a20f5c1314f299ade4973ff1f4cad.WebRole.LocalStorage1\v78.zip' because it is being used by another process. The code is given below: string localPath = RoleEnvironment.GetLocalResource("LocalStorage1").RootPath; Response.Write(localPath + " \n"); Directory.SetCurrentDirectory(localPath); CloudBlob mblob = GetProgramContainer().GetBlobReference("v78.zip"); CloudBlockBlob mbblob = mblob.ToBlockBlob; CloudBlob zipblob = GetProgramContainer().GetBlobReference("7z.exe"); string zipPath = Path.Combine(localPath, "7z.exe"); string matlabPath = Path.Combine(localPath, "v78.zip"); IEnumerable<ListBlockItem> blocklist = mbblob.DownloadBlockList(); BlobStream stream = mbblob.OpenRead(); FileStream fs = File.Create(matlabPath); (Exception occurs here) It'll be great help if someone could tell me where I'm going wrong. Thanks! Shan

• Maven String Replace of Text Web Resources

  - by Jaco van Niekerk

  I have a Maven web application with text files in src/main/webapp/textfilesdir As I understand it, during the package phase this textfilesdir directory will be copied into the target/project-1.0-SNAPSHOT directory, which is then zipped up into a target/project-1.0-SNAPSHOT.war Problem Now, I need to do a string replacement on the contents of the text files in target/project-1.0-SNAPSHOT/textfilesdir. This must then be done after the textfilesdir is copied into target/project-1.0-SNAPSHOT, but prior to the target/project-1.0-SNAPSHOT.war file being created. I believe this is all done during the package phase. How can a plugin (potentially maven-antrun-plugin), plug into the package phase to do this. The text files don't contain properties, like ${property-name} to filter on. String replacement is likely the only option. Options Modify the text files after the copy into target/project-1.0-SNAPSHOT directory, yet prior to the WAR creation. After packaging, extract the text files from WAR, modify them, and add them back into the WAR. I'm thinking there is another option here I'm missing. Thoughts anyone?

• Clarification needed: How does .NET runtime resolve assembly references from parent folder?

  - by aoven

  I have the following output structure of executables in my solution: %ProgramFiles% | +-[MyAppName] | +-[Client] | | | +-(EXE & several DLL assemblies) | +-[Common] | | | +-[Schema Assemblies] | | | | | +-(several DLL assemblies) | | | +-(several DLL assemblies) | +-[Server] | +-(EXE & several DLL assemblies) Each project in solution references different DLL assemblies, some of which are outputs from other projects in solution, and others are plain 3rd-party assemblies. For example, [Client] EXE might reference an assembly in [Common], which is in a different directory branch. All references have "Copy Local" set to false, to mirror the layout of the files in the final installed application. Now, if I take a look at reference properties in the Visual Studio IDE, I see that "Path" of every reference is absolute and that it corresponds to the actual output location of the assembly. That's understandable and correct. As expected, solution compiles and runs just fine. What I don't understand is, why everything seems to work even when I close the IDE, rename the [MyAppName] directory and run the [Client] EXE manually? How does the runtime find the assemblies if the reference paths aren't the same as they were at the time of linking? To be clear - this is actually exactly what I'm after: a semi-dispersed set of application files that run fine regardless of where the [MyAppName] directory is located or even what it's named. I'd just like to know, how and why this works without any specific path resolution on my part. I've read the answers to this similar question, but I still don't get it. Help much appreciated!

• Security implications of writing files using PHP

  - by susmits

  I'm currently trying to create a CMS using PHP, purely in the interest of education. I want the administrators to be able to create content, which will be parsed and saved on the server storage in pure HTML form to avoid the overhead that executing PHP script would incur. Unfortunately, I could only think of a few ways of doing so: Setting write permission on every directory where the CMS should want to write a file. This sounds like quite a bad idea. Setting write permissions on a single cached directory. A PHP script could then include or fopen/fread/echo the content from a file in the cached directory at request-time. This could perhaps be carried out in a Mediawiki-esque fashion: something like index.php?page=xyz could read and echo content from cached/xyz.html at runtime. However, I'll need to ensure the sanity of $_GET['page'] to prevent nasty variations like index.php?page=http://www.bad-site.org/malicious-script.js. I'm personally not too thrilled by the second idea, but the first one sounds very insecure. Could someone please suggest a good way of getting this done?
