• Eclipse CDT: Import source / header files into my new project, without duplicating them

  - by Tom

  Hi all, Im sure there is a very simple solution for this. I have a bunch of .cpp / .h files from a project, say in directory ~/files On the other hand, I want to create a c++ project using eclipse to work on those files, so I put my workspace on ~/wherever. Then I create a c++ project: ~/wherever/project, and include the source files (located in /~files). The problem i'm having is that files are now duplicated in ~/wherever/project, and I would like to avoid that, specially so I know which copy of the file to commit. Is this possible? Im sure it is, but cant get it. Thanks in advance.

• Chinese encoding issue while listing files

  - by Null Pointer

  I am running a Java application on a Solaris10 with Chinese. Now there are some files in a directory with chinese filenames. When I do files = new File(dir).list() where "dir" is the parent directory containing that chinese file, I get the result filename files[0] as ?????(some junk characters). Now the deal is that my programs file.encoding property is already set to GBK and I also do Charset.isSupported("GBK") and it returns true too. So where could be the problem. I am running out of ideas. NOTE: I am not trying to print the filename anywhere or copy the file or something. I am simply openeing a stream to it, something like below: files = new File(dir).list(); new FileInputStream(files[0]); Now this gives me a FileNotFoundExcpetion, so I debug just to find that value inside files[0] is "??????".

• Find who's calling the method

  - by Marcos Placona

  Hi, I'd like to somehow find out which CFC is calling my method. I have a logging CFC which is called by many different CFC's. On this logging CFC there's a need to store which CFC called for the log. Whilst I could simply pass the CFC name as an argument to my log.cfc, I find this to be a repetitive task, that might not be necessary, if I somehow could find out "who's" calling the method on log.cfc Is there any programmatic way of achieving this? Thanks in advance

• Visual Studio "Find" results in "No files were found to look in. Find stopped progress."

  - by suryasonti

  Sometimes while developing in Visual Studio IDE, when you use "Find in Files" dialog to find something, the search fails and you will see the following message in the "Find Results" window. "No files were found to look in. Find stopped progress." Once this message shows-up all the subsequent searches will result in the same message. Nothing fixes the problem including restarting computer except Pressing "Ctrl + ScrLk". Does anyone know what causes VisualStudio to get into this state and is there a setting to permanently prevent it from happening?

• Perl - Internal File (create and execute)

  - by drewrockshard

  I have a quick question about creating files with perl and executing them. I wanted to know if it was possible to generate a file using perl (I actually need a .bat script) and then execute this file internally to the program. I know I can create files, and I have with perl, however, I'm wanting to do this internally to the program. So, what I want it to do is actually create a batch script internally to the program (no file is actually written to the disk, everything remains in memory, or the perl program), and then once it completes the writing of the file, I'd like to be able to actually execute this file, and then discard the file it just wrote. I'm basically trying to have it create a batch script on the fly, so that I can just have output text files from the output of the script, rather than creating the batch script on disk, then executing it, and then deleting the batch file from disk when its done. Can this be done and how would I go about doing this? Regards, Drew

• Change Check Out Folder for checked out files in SourceSafe

  - by Town

  I had to rebuild my machine and went from XP to Windows 7. I've now got a bit of an issue: I had files checked out in SourceSafe previously, which I still have copies of in the local folder on my new install. However, SourceSafe still has them checked out to the old XP folder (c:\documents and settings etc) whereas the files now reside in c:\Users. Pending Checkins in Visual Studio now thinks I have nothing checked out, and SourceSafe declares that the files are checked out to me under the c:\documents and settings\ path. Is there any way to tell SourceSafe to simply "look over there" for the files instead? It seems to work with individually undoing and redoing checkout on the files, but that's a lengthy process and one I'd like to avoid if possible. If I simply checkout the files individually then it lists them as checked out to me twice, one for each of the locations. Any pointers would be very much appreciated!

• How to enable error log in lighttpd properly?

  - by Tomaszs

  I have a Centos 5 system with Lighttpd and fastcgi enabled. It does log access but does not log errors. I have Internal Server Error 500 and no info in log and when I try to open not -existing file also - no info in error log. How to enable it properly? Below is list of modules that I've enabled: server.modules = ( "mod_rewrite", "mod_redirect", "mod_alias", # "mod_access", # "mod_cml", # "mod_trigger_b4_dl", # "mod_auth", "mod_status", "mod_setenv", "mod_fastcgi", # "mod_webdav", # "mod_proxy_core", # "mod_proxy_backend_fastcgi", # "mod_proxy_backend_scgi", # "mod_proxy_backend_ajp13", # "mod_simple_vhost", # "mod_evhost", # "mod_userdir", # "mod_cgi", # "mod_compress", # "mod_ssi", # "mod_usertrack", # "mod_expire", # "mod_secdownload", # "mod_rrdtool", "mod_accesslog" ) Here are setting of debugging: ## enable debugging #debug.log-request-header = "enable" #debug.log-response-header = "enable" #debug.log-request-handling = "enable" debug.log-file-not-found = "enable" #debug.log-condition-handling = "enable" Setting of path to error and access log: ## where to send error-messages to server.errorlog = "/home/lxadmin/httpd/lighttpd/error.log" #### accesslog module accesslog.filename = "/home/lxadmin/httpd/lighttpd/ligh.log" Settings of fastcgi: fastcgi.debug = 1 fastcgi.server = ( ".php" => (( "bin-path" => "/usr/bin/php-cgi", "socket" => "/tmp/php.socket", "max-procs" => 12, "bin-environment" => ( "PHP_FCGI_CHILDREN" => "2", "PHP_FCGI_MAX_REQUESTS" => "500" ) ))) And in included config file I have: server.errorlog = "/home/httpd/mywebsite.com/stats/mywebsite.com-error_log" What comes to log files: /home/httpd/mywebsite.com/stats/ -rw-r--r-- 1 apache apache 5173239 May 16 11:34 mywebsite.com-custom_log -rwxrwxrwx 1 root root 0 Mar 27 2009 mywebsite.com-error_log /home/lxadmin/httpd/lighttpd/ -rwxrwxrwx 1 apache apache 2184 Apr 22 22:59 error.log -rwxrwxrwx 1 apache apache 6088621 May 16 11:26 ligh.log I gave error logs chmod 777 for a try to check if it's the issue, but apparently it's not. So my question is: what to do to have error log enabled?

• Trying to find a match in two strings - Python

  - by Jacob Mammoliti

  I have a user inputting two strings and then I want to check if there are any similar characters and if there is, get the position where the first similarity occurs, without using the find or index function. Below is what I have so far but I doesn't fully work. With what I have so far, I'm able to find the similarities but Im not sure how to find the position of those similarities without using the index function. string_a = "python" string_b = "honbe" same = [] a_len = len(string_a) b_len = len(string_b) for a in string_a: for b in string_b: if a == b: same.append(b) print (same) Right now the output is: ['h', 'o', 'n'] So basically what I am asking is, how can I find the position of those characters without using the Python Index function?

• C# Binary File Compare

  - by Simon Farrow

  I'm in a situation where I want to compare two binary files. One of them is already stored on the server with a pre-calculated Crc32 in the database from when I stored it originally. I know that if the Crc is different then the files are definitely different. However, if the Crc is the same I don't know that the files are. So what I'm looking for is a nice efficient way of comparing the two streams on from the posted file and one from the file system. I'm not an expert on streams but I'm well aware that I could easily shoot myself in the foot here as far as memory usage is concerned. Any help is greatly appreciated.

• Split big Apache log to folder structure

  - by Dough

  I just changed my Apache log behavior because it was making me having very BIG files... So I now use cronolog to split my logs to log/httpd/2012/11/access_2012.11.30.log for exemple, pattern : %Y/%m/access_%Y.%m.%d.log I now want to split my old 42GB file to the same structure but really don't know how to do that efficiently. I tried some simple commands with cat, egrep, awk... but really don't know how to handle all that in a more powerful script. Here is how the log looks like : x.x.237.134 - - [08/Apr/2011:14:43:09 +0200] "GET... x.x.50.15 - - [08/Apr/2011:14:43:09 +0200] "GET... [...] x.x.254.19 - - [28/Feb/2012:15:24:48 +0100] "GET... So I need for yeah line to get : year %Y (ex. 2012) month %m (ex. 11) day %d And to push out the entire line to : %Y/%m/access_%Y.%m.%d.log Can someone give me clues to get that working ? Thanks a lot for your interest.

• Looking for suitable backup solution Mac OS X to offsite Centos 6 server 1TB of working data

  - by Brady

  I'll start by saying what we have in place currently: On site file server (Mac OS X Server) that is used by GFX designers and they have a working 1TB of data. Offsite server with 2TB available storage (Centos 6) Mac OS X server rsync data to offsite server every 6 hours (rsync -avz --delete --progress -e ssh ...) Mac OS X server does full data backup to LTO 4 tape on a 10 day recycle (Mon-Fri for 2 weeks) rsync pushes about 60GB of file changes a day. The problem: The onsite tape backup is failing as 1TB of graphics files don't compress well to fit onto a 800GB LTO4 tape. Backup is incredibly slow doing a full backup. Pain in the backside getting people to remember to change the tape. Often gets forgotten etc The quick solution: Buy LTO5 Drive and tapes. However this has been turned down because of the cost... What I would like: Something that works in the same way rysnc works. Only changed data is sent over the wire and can be scheduled to run multiple times during the day. Data that is sent is compressed and sent over SSH. Something that keeps a 14day retention but doesn't keep duplicate data So as an example if I have 1TB of working data and 60GB of changes are made each day then I expect around 1.84TB of data to be stored on the offsite server. To work with the Mac OS X server and Centos 6 server. Not cost an arm and a leg. Must be a cheaper solution than buying an LTO5 drive with tapes (around £1500). Be able to be setup to run autonomously. Have some sort of control panel that will allow an admin to easily restore a file/folder. Any recommendations?

• combine two GCC compiled .o object files into a third .o file

  - by ~lucian.grijincu

  How does one combine two GCC compiled .o object files into a third .o file? $ gcc -c a.c -o a.o $ gcc -c b.c -o b.o $ ??? a.o b.o -o c.o $ gcc c.o other.o -o executable If you have access to the source files the -combine GCC flag will merge the source files before compilation: $ gcc -c -combine a.c b.c -o c.o However this only works for source files, and GCC does not accept .o files as input for this command. Normally, linking .o files does not work properly, as you cannot use the output of the linker as input for it. The result is a shared library and is not linked statically into the resulting executable. $ gcc -shared a.o b.o -o c.o $ gcc c.o other.o -o executable $ ./executable ./executable: error while loading shared libraries: c.o: cannot open shared object file: No such file or directory $ file c.o c.o: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, not stripped $ file a.o a.o: ELF 32-bit LSB relocatable, Intel 80386, version 1 (SYSV), not stripped

• Check to see if file transfer is complete

  - by Cymon

  We have a daily job that processes files delivered from an external source. The process usually runs fine without any issues but every once in a while we have an issue of attempting to process a file that is not completely transferred. The external source SCPs these files from a UNIX server to our Windows server. From there we try to process the files. Is there a way to check to see if a file is still being transferred? Does UNIX put a lock on a file while SCPing it that we could check on the Windows side?

• Using Visual sudio .ncb file for reflection.

  - by Rushi

  I am developing visual game level editor in c++. For this I want reflection(RTTI) mechanism to know class attributes at runtime. I am currently using PDB files for this.But using PDB I couldn't retrieve actual code line for extra information in commented format which is given for that attribute. Visual studio uses NCB files for intelligence. So will it be better idea to use NCB instead PDB? If yes,How to retrieve information from NCB files? Is there any SDK like DIA SDK?

• C1083 : Permission denied on .sbr files

  - by speps

  Hello, I am using Visual Studio 2005 (with SP1) and I am getting weird errors concerning .sbr files. These files, as I read on MSDN, are intermediate files for BSCMAKE to generate a .bsc file. The errors I get are, for example (on different builds) : 11string.cpp : fatal error C1083: Impossible d'ouvrir le fichier généré(e) par le compilateur : '.\debug\String.sbr' : Permission denied 58type.cpp : fatal error C1083: Impossible d'ouvrir le fichier généré(e) par le compilateur : '.\Debug/Type.sbr' : Permission denied Translation : cannot open compiler intermediate file It seems to be consistent (I have at least 5 or 6 examples like this) with a .cpp file being compiled twice in the same project, respectively : 11String.cpp *some warnings, 2 lines* 11String.cpp 58Type.cpp *some warnings and other files compiled, a lot of lines* 58Type.cpp I already checked the .vcproj files for duplicate entries and it does not seem to be the problem. I would appreciate any help regarding this issue. Deactivating the build of .bsc files seems to be a workaround but maybe someone has better information than this. Thanks.

• acts-as-taggable-on find within specific tag context

  - by user284194

  I have two models (entries and messages) using acts-as-taggable-on for tagging. How do I write a find condition for tagged messages from only the one model and not both? The only way I can get the tagged items to display is through the basic find: @tags = Tag.find(:all) But this displays tags from both the entries model and the messages model. How can I find the tags from just the messages model? I'm really new to Rails and ActiveRecord finds. I appreciate any help you can offer. Thank you for reading my question.

• How to Enable IPtables TRACE Target on Debian Squeeze (6)

  - by bernie

  I am trying to use the TRACE target of IPtables but I can't seem to get any trace information logged. I want to use what is described here: Debugger for Iptables. From the iptables man for TRACE: This target marks packes so that the kernel will log every rule which match the packets as those traverse the tables, chains, rules. (The ipt_LOG or ip6t_LOG module is required for the logging.) The packets are logged with the string prefix: "TRACE: tablename:chain- name:type:rulenum " where type can be "rule" for plain rule, "return" for implicit rule at the end of a user defined chain and "policy" for the policy of the built in chains. It can only be used in the raw table. I use the following rule: iptables -A PREROUTING -t raw -p tcp -j TRACE but nothing is appended either in /var/log/syslog or /var/log/kern.log! Is there another step missing? Am I looking in the wrong place? edit Even though I can't find log entries, the TRACE target seems to be set up correctly since the packet counters get incremented: # iptables -L -v -t raw Chain PREROUTING (policy ACCEPT 193 packets, 63701 bytes) pkts bytes target prot opt in out source destination 193 63701 TRACE tcp -- any any anywhere anywhere Chain OUTPUT (policy ACCEPT 178 packets, 65277 bytes) pkts bytes target prot opt in out source destination edit 2 The rule iptables -A PREROUTING -t raw -p tcp -j LOG does print packet information to /var/log/syslog... Why doesn't TRACE work?

• Is my webserver being abused for banking fraud?

  - by koffie

  Since a few weeks i'm getting a lot of 403 errors from apache in my log files that seem to be related to a bank frauding scheme. The relevant log entries look like this (The ip 1.2.3.4 is one I made up, I did not modify the rest of each line) www.bradesco.com.br:80 / 1.2.3.4 - - [01/Dec/2012:07:20:32 +0100] "GET / HTTP/1.1" 403 427 "-" "Mozilla/5.0 (Windows NT 5.1) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.56 Safari/535.11" www.bb.com.br:80 / 1.2.3.4 - - [01/Dec/2012:07:20:32 +0100] "GET / HTTP/1.1" 403 370 "-" "Mozilla/5.0 (Windows NT 5.1) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.56 Safari/535.11" www.santander.com.br:80 / 1.2.3.4 - - [01/Dec/2012:07:20:33 +0100] "GET / HTTP/1.1" 403 370 "-" "Mozilla/5.0 (Windows NT 5.1) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.56 Safari/535.11" www.banese.com.br:80 / 1.2.3.4 - - [01/Dec/2012:07:20:33 +0100] "GET / HTTP/1.1" 403 370 "-" "Mozilla/5.0 (Windows NT 5.1) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.56 Safari/535.11" the logformat I use is: LogFormat "%V:%p %U %h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" The strange thing is that all these domains are domains of banks and 3 out of the 4 domains are also in the list of the bank frauding scheme described on: http://www.abuse.ch/?p=2925 I would really like to know if my server is being abused for bank frauding or not. I suspect not, because it's giving 403 to all requests. But any extra checks that I can do to ensure that my server is not being abused are welcome. I'm also curious on how the "bad guys" expected my server to behave. I.e. are they just expecting my server to act as a proxy to hide the ip of the fake site, or are they expecting that my server will actually serve the fake banking website? Is the ip 1.2.3.4 more likely to be the ip of a victim or the ip of a bad guy. I suspect a bad guy, because it's quite unlikely that a real person would visit 4 bank sites in a second. If it's from a bad guy I'm very curious at what he is trying to do.

• Most scalable way of serving a small set of static HTTP content

  - by Ekevoo

  The story: Hi guys. I'm among the people responsible for serving the results of the most anticipated (by number of people participating) annual entrance exam in my state. As such, when our results are published, the interest is overwhelming. In the past we delegated the responsibility of serving the results to the media, but that spoils a little the officialness of these results. This year we went with a little (long overdue) experiment of using lighttpd instead of Apache as well as other physical network optimizations I wasn't directly involved with. The results were very satisfactory. The server didn't choke even once, nor we saw any of the usual Twitter complaints on unavailability and/or slowness that were previously common. However, because we still delegated the first publication of the results to the media I'm still not 100% sure we can handle the load of actually publishing the results first. The question: Now because these files are like 14MB in total and a true lightweight Linux distribution isn't that big either, I'm thinking: what if next year we run full RAMdrive? Is there any? Is that useful? Is that worth it for a team that uses Debian almost exclusively? Are there other optimizations that I should be focusing on instead?
