• c++ program debugged well with Cygwin4 (under Netbeans 7.2) but not with MinGW (under QT 4.8.1)

  - by GoldenAxe

  I have a c++ program which take a map text file and output it to a graph data structure I have made, I am using QT as I needed cross-platform program and GUI as well as visual representation of the map. I have several maps in different sizes (8x8 to 4096x4096). I am using unordered_map with a vector as key and vertex as value, I'm sending hash(1) and equal functions which I wrote to the unordered_map in creation. Under QT I am debugging my program with QT 4.8.1 for desktop MinGW (QT SDK), the program works and debug well until I try the largest map of 4096x4096, then the program stuck with the following error: "the inferior stopped because it received a signal from operating system", when debugging, the program halt at the hash function which used inside the unordered_map and not as part of the insertion state, but at a getter(2). Under Netbeans IDE 7.2 and Cygwin4 all works fine (debug and run). some code info: typedef std::vector<double> coordinate; typedef std::unordered_map<coordinate const*, Vertex<Element>*, container_hash, container_equal> vertexsContainer; vertexsContainer *m_vertexes (1) hash function: struct container_hash { size_t operator()(coordinate const *cord) const { size_t sum = 0; std::ostringstream ss; for ( auto it = cord->begin() ; it != cord->end() ; ++it ) { ss << *it; } sum = std::hash<std::string>()(ss.str()); return sum; } }; (2) the getter: template <class Element> Vertex<Element> *Graph<Element>::getVertex(const coordinate &cord) { try { Vertex<Element> *v = m_vertexes->at(&cord); return v; } catch (std::exception& e) { return NULL; } } I was thinking maybe it was some memory issue at the beginning, so before I was thinking of trying Netbeans I checked it with QT on my friend pc with a 16GB RAM and got the same error. Thanks.

• Strange issue with cout

  - by ben

  After reading from a text file, and storing it into a string, I tried to pass this message into another function that will print it out. This is what it looks like: http://imgur.com/MCjfRdp void insert (int id, string message){ cout << "Inserting " << message << " at" << endl; } Somehow the message behind the string overrides the message. But once I removed the " at" after message, it worked as expected. http://imgur.com/JdHPPmi void insert (int id, string message){ cout << "Inserting " << message << endl; } I somehow suspect the problem came from stringstream, but i couldn't find out where. Here's the code that read from file vector <string> line; fstream infile; string readLine, tempLine, action, tempLine1; int level, no; infile.open(fileName.c_str(),ios::in); int i = 0; while (!infile.eof()) { getline (infile, readLine); line.push_back(readLine); } infile.close(); line.pop_back(); for (int i = 0; i < line.size();i++) { stringstream ss (line.at(i)); getline (ss, action, ' '); if (action == "init") { // some other work here } else if (action == "insert") { tempLine = line.at(i); ss >> no; stringstream iline(tempLine); getline (iline, tempLine1, ' '); getline (iline, tempLine1, ' '); getline (iline, tempLine1, '\n'); Insert (no, tempLine1); } Since my file has different kinds of actions, here is what test.dat contains: insert 0 THIS IS A TEST edit: When i did file.txt, it came out as something like this. Inserting THIS IS A TEST at Inserting THIS IS TEST NO 2 at

• Use variables entered in login page usable in multiple pages?

  - by deception1

  I have a Login page that captures User input like this. MD5calc ss = new DBCon.MD5calc(); string gs = ss.CalculateMD5Hash(password.Password); int unitID = Convert.ToInt32(Unit_ID.Text); logBO.UnitID = unitID; logBO.UserID = User_name.Text; logBO.UserPass = gs; How would i make them assignable to any other page i created.My Common sense says that creating a static class would be enough,but will it?If i do create a static class where would i put it and how would i call it?I actually need those variable to use in my Sql Stored procedures.

• Installing Lubuntu 14.04.1 forcepae fails

  - by Rantanplan

  I tried to install Lubuntu 14.04.1 from a CD. First, I chose Try Lubuntu without installing which gave: ERROR: PAE is disabled on this Pentium M (PAE can potentially be enabled with kernel parameter "forcepae" ... Following the description on https://help.ubuntu.com/community/PAE, I used forcepae and tried Try Lubuntu without installing again. That worked fine. dmesg | grep -i pae showed: [ 0.000000] Kernel command line: file=/cdrom/preseed/lubuntu.seed boot=casper initrd=/casper/initrd.lz quiet splash -- forcepae [ 0.008118] PAE forced! On the live-CD session, I tried installing Lubuntu double clicking on the install button on the desktop. Here, the CD starts running but then stops running and nothing happens. Next, I rebooted and tried installing Lubuntu directly from the boot menu screen using forcepae again. After a while, I receive the following error message: The installer encountered an unrecoverable error. A desktop session will now be run so that you may investigate the problem or try installing again. Hitting Enter brings me to the desktop. For what errors should I search? And how? Finally, I rebooted once more and tried Check disc for defects with forcepae option; no errors have been found. Now, I am wondering how to find the error or whether it would be better to follow advice c in https://help.ubuntu.com/community/PAE: "Move the hard disk to a computer on which the processor has PAE capability and PAE flag (that is, almost everything else than a Banias). Install the system as usual but don't add restricted drivers. After the install move the disk back." Thanks for some hints!

• SQL SERVER – Display Datetime in Specific Format – SQL in Sixty Seconds #033 – Video

  - by pinaldave

  A very common requirement of developers is to format datetime to their specific need. Every geographic location has different need of the date formats. Some countries follow the standard of mm/dd/yy and some countries as dd/mm/yy. The need of developer changes as geographic location changes. In SQL Server there are various functions to aid this requirement. There is function CAST, which developers have been using for a long time as well function CONVERT which is a more enhanced version of CAST. In the latest version of SQL Server 2012 a new function FORMAT is introduced as well. In this SQL in Sixty Seconds video we cover two different methods to display the datetime in specific format. 1) CONVERT function and 2) FORMAT function. Let me know what you think of this video. Here is the script which is used in the video: -- http://blog.SQLAuthority.com -- SQL Server 2000/2005/2008/2012 onwards -- Datetime SELECT CONVERT(VARCHAR(30),GETDATE()) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),10) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),110) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),5) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),105) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),113) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),114) AS DateConvert; GO -- SQL Server 2012 onwards -- Various format of Datetime SELECT CONVERT(VARCHAR(30),GETDATE(),113) AS DateConvert; SELECT FORMAT ( GETDATE(), 'dd mon yyyy HH:m:ss:mmm', 'en-US' ) AS DateConvert; SELECT CONVERT(VARCHAR(30),GETDATE(),114) AS DateConvert; SELECT FORMAT ( GETDATE(), 'HH:m:ss:mmm', 'en-US' ) AS DateConvert; GO -- Specific usage of Format function SELECT FORMAT(GETDATE(), N'"Current Time is "dddd MMMM dd, yyyy', 'en-US') AS CurrentTimeString; This video discusses CONVERT and FORMAT in simple manner but the subject is much deeper and there are lots of information to cover along with it. I strongly suggest that you go over related blog posts in next section as there are wealth of knowledge discussed there.

• Segfault when iterating over a map<string, string> and drawing its contents using SDL_TTF

  - by Michael Stahre

  I'm not entirely sure this question belongs on gamedev.stackexchange, but I'm technically working on a game and working with SDL, so it might not be entirely offtopic. I've written a class called DebugText. The point of the class is to have a nice way of printing values of variables to the game screen. The idea is to call SetDebugText() with the variables in question every time they change or, as is currently the case, every time the game's Update() is called. The issue is that when iterating over the map that contains my variables and their latest updated values, I get segfaults. See the comments in DrawDebugText() below, it specifies where the error happens. I've tried splitting the calls to it-first and it-second into separate lines and found that the problem doesn't always happen when calling it-first. It alters between it-first and it-second. I can't find a pattern. It doesn't fail on every call to DrawDebugText() either. It might fail on the third time DrawDebugText() is called, or it might fail on the fourth. Class header: #ifndef CLIENT_DEBUGTEXT_H #define CLIENT_DEBUGTEXT_H #include <Map> #include <Math.h> #include <sstream> #include <SDL.h> #include <SDL_ttf.h> #include "vector2.h" using std::string; using std::stringstream; using std::map; using std::pair; using game::Vector2; namespace game { class DebugText { private: TTF_Font* debug_text_font; map<string, string>* debug_text_list; public: void SetDebugText(string var, bool value); void SetDebugText(string var, float value); void SetDebugText(string var, int value); void SetDebugText(string var, Vector2 value); void SetDebugText(string var, string value); int DrawDebugText(SDL_Surface*, SDL_Rect*); void InitDebugText(); void Clear(); }; } #endif Class source file: #include "debugtext.h" namespace game { // Copypasta function for handling the toString conversion template <class T> inline string to_string (const T& t) { stringstream ss (stringstream::in | stringstream::out); ss << t; return ss.str(); } // Initializes SDL_TTF and sets its font void DebugText::InitDebugText() { if(TTF_WasInit()) TTF_Quit(); TTF_Init(); debug_text_font = TTF_OpenFont("LiberationSans-Regular.ttf", 16); TTF_SetFontStyle(debug_text_font, TTF_STYLE_NORMAL); } // Iterates over the current debug_text_list and draws every element on the screen. // After drawing with SDL you need to get a rect specifying the area on the screen that was changed and tell SDL that this part of the screen needs to be updated. this is done in the game's Draw() function // This function sets rects_to_update to the new list of rects provided by all of the surfaces and returns the number of rects in the list.

• Cannot get Virtualbox to install properly on Ubuntu 12.04

  - by lopac1029

  I cannot get Virtualbox to install properly on my 12.04. I first went with a manual install for the .deb from the old builds section of the Virtualbox page. That .deb opened up the Software Center and installed. Then I got the error coming up of VT-x/AMD-V hardware acceleration is not available on your system. Your 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot. which I can only assume was due to my Ubuntu version being 32-bit (System Details - Overview - OC type: 32-bit, right?) So I followed these instructions to remove the .deb manually, restarted my laptop, and then FOUND the actual Virtualbox install in the Software Center and installed from that (assuming it would give me the correct version I need for my system) So after all that (and then some), I'm still getting the same error when I connect to my new job's project in Virtualbox. Can anyone point me in the right direction of what to do here? This is the first time I've ever worked with Virtualbox, and no one at this company is using Ubuntu, so I'm on my own here.

  Here's an Oracle NoSQL Database customer success story for Passoker, an online betting house. http://www.oracle.com/us/corporate/customers/customersearch/passoker-1-nosql-ss-1863507.html There are a lot of great points made in the Solutions section, but as a developer the one I like the most is this one: Eliminated daily maintenance related to single-node points-of-failure by moving to Oracle NoSQL Database, which is designed to be resilient and hands-off, thus minimizing IT support costs

• Pain removing a perl rootkit

  - by paul.ago

  So, we host a geoservice webserver thing at the office. Someone apparently broke into this box (probably via ftp or ssh), and put some kind of irc-managed rootkit thing. Now I'm trying to clean the whole thing up, I found the process pid who tries to connect via irc, but i can't figure out who's the invoking process (already looked with ps, pstree, lsof) The process is a perl script owned by www user, but ps aux |grep displays a fake file path on the last column. Is there another way to trace that pid and catch the invoker? Forgot to mention: the kernel is 2.6.23, which is exploitable to become root, but I can't touch this machine too much, so I can't upgrade the kernel EDIT: lsof might help: lsof -p 9481 COMMAND PID USER FD TYPE DEVICE SIZE NODE NAMEss perl 9481 www cwd DIR 8,2 608 2 /ss perl 9481 www rtd DIR 8,2 608 2 /ss perl 9481 www txt REG 8,2 1168928 38385 /usr/bin/perl5.8.8ss perl 9481 www mem REG 8,2 135348 23286 /lib64/ld-2.5.soss perl 9481 www mem REG 8,2 103711 23295 /lib64/libnsl-2.5.soss perl 9481 www mem REG 8,2 19112 23292 /lib64/libdl-2.5.soss perl 9481 www mem REG 8,2 586243 23293 /lib64/libm-2.5.soss perl 9481 www mem REG 8,2 27041 23291 /lib64/libcrypt-2.5.soss perl 9481 www mem REG 8,2 14262 23307 /lib64/libutil-2.5.soss perl 9481 www mem REG 8,2 128642 23303 /lib64/libpthread-2.5.soss perl 9481 www mem REG 8,2 1602809 23289 /lib64/libc-2.5.soss perl 9481 www mem REG 8,2 19256 38662 /usr/lib64/perl5/5.8.8/x86_64-linux-threa d-multi/auto/IO/IO.soss perl 9481 www mem REG 8,2 21328 38877 /usr/lib64/perl5/5.8.8/x86_64-linux-threa d-multi/auto/Socket/Socket.soss perl 9481 www mem REG 8,2 52512 23298 /lib64/libnss_files-2.5.soss perl 9481 www 0r FIFO 0,5 1068892 pipess perl 9481 www 1w FIFO 0,5 1071920 pipess perl 9481 www 2w FIFO 0,5 1068894 pipess perl 9481 www 3u IPv4 130646198 TCP 192.168.90.7:60321-www.**.net:ircd (SYN_SENT)

• NFSv3 + ACL: mask is gone on clients

  - by Jorge Suárez de Lis

  I'm sharing a NFS folder among a user group. The default umask on the clients is 0700, and this is a problem because newly created files won't be readable/writable by another users. So, I'm using ACLs to force the umask 0770 on the shared folder, and this works OK on the server, but not on the clients. server # getfacl /export/proyectos getfacl: Eliminando «/» inicial en nombres de ruta absolutos # file: export/proyectos # owner: root # group: root user::rwx group::rwx other::r-x default:user::rwx default:group::rwx default:mask::rwx default:other::r-x server # getfacl /export/proyectos/innovacion getfacl: Eliminando «/» inicial en nombres de ruta absolutos # file: export/proyectos/innovacion # owner: root # group: proyecto-innovacion # flags: ss- user::rwx group::rwx mask::rwx other::--- default:user::rwx default:group::rwx default:mask::rwx default:other::--- As you see, the default (and also a specific on the second directory) mask ACLs are being applied. I mount the whole share on the client: 172.16.54.56:/export/proyectos on /proyectos type nfs (rw,noatime,rsize=131072,wsize=131072,acregmin=10,acl,nfsvers=3,addr=172.16.54.56) But the mask and default:mask ACLs are gone. client $ getfacl /proyectos/ getfacl: Eliminando «/» inicial en nombres de ruta absolutos # file: proyectos/ # owner: root # group: root user::rwx group::rwx other::r-x default:user::rwx default:group::rwx default:other::r-x client $ getfacl /proyectos/innovacion getfacl: Eliminando «/» inicial en nombres de ruta absolutos # file: proyectos/innovacion # owner: root # group: proyecto-innovacion # flags: ss- user::rwx group::rwx other::--- default:user::rwx default:group::rwx default:other::--- It lacks the default:mask and mask ACLs, the only ones that I've setted. So the proposed solution to enforce umask won't work for me. Why is happening this?

• Powershell Copy-Item fails silently

  - by R W

  I have a powershell 2.0 script running on Windows Server 2008 R2 64bit that copies some Hyper-V .vhd files to another server as a 'backup solution'. The script gets a list of the .vhd's to copy then iterates over that list to copy them using Copy-Item. It also writes some logging info to a file as well. The files are copied to another server (Windows Server 2003 Sp2) into a directory compressed with NTFS compression. One of the files isn't copied. It's relatively big ~ 68Gb. The others are 20Gb or less. The wierd thing is that during the copy process the file appears on the destination server and the log file generated seems to indicate the file is copied due to the difference in the times of the log file entries. I see no error messages on the log file and nothing in the event log of either machine. Here's the code that does the copy. Get-ChildItem $VMSource *.vhd -Recurse | foreach-object { $time = Get-Date -format HH.mm.ss Add-Content $logFileName "$time : File Copy ($_) started" $fullname = $_.FullName Add-Content $logFileName "$time : Copying $fullname to $VMDestination" Copy-Item $fullname $VMDestination -Force -ErrorAction SilentlyContinue -ErrorVariable errors foreach($error in $errors) { if ($error.Exception -ne $null) { Add-Content $logFileName "'tERROR COPYING FILE : $($error.Exception)" } } $time = Get-Date -format HH.mm.ss Add-Content $logFileName "$time : File Copy ($_) finished" } I can only think there's some problem with copying a file that big to a compressed directory maybe? Any ideas?

• Emails sent through SMTP on VPS are considered to be spam

  - by Ilya

  During our business we have to make regular mailing to our clients: invoices, information emails, etc. Previously we received and sent emails using mail server of our hosting provider. But as the number of clients increased, we have to order VPS and install our own SMTP server their for performing our mailings. So, now we have default provider mail server for receiving emails, let it be business.com. We have email accounts like [email protected], etc. We use this mail server to receive emails and manage our email accounts. And we have SMTP server which is running on VPS. We use this SMTP only for sending emails with From addresses like [email protected]. VPS has default DNS records created by provider, let it be IP.AD.RE.SS <- ip-ad-re-ss.provider.com. Mailings are made using either desktop email clients or custom Java-based application which uses JavaMail for sending emails. The problem is that most of emails sent by us are placed in spam folders in clients email accounts. Clients have their email in Gmail, Yahoo, Hotmail, etc. Could you please tell what is the most probable reason and solution of described problem? Are there any service in Intranet where we can send test email and get an answer with description why this email could be considered to be spam?

• APACHE - PHP - Bounce emails

  - by user1179459

  I want to improve our mail server lists by handling all the bounces we get in our websites. I have a website which has over 8000+ users and another website which as over 1500+ users, they are emailed various notifications every second, ie. job alerts, email alerts, I am using POP connections with EXIM on APACHE server, most scripts are based on PHP language generates email on the fly. Problems i have But some users has registered long time ago and now quite few has bounce email address Some users register with dummy emails like [email protected] which never existed but a valid email address, any chance of stopping this without asking them login to the email account and clicking links which dont work most times.. (too annoying to the end user) Server is sending unnecessary emails can be avoided if i know they dont exists ? Solutions i need to have Is there a way i can download the bounce email list somewhere (WHM/Cpanel), i know exim mail has it but its not readable (i need a file like CSV or something similar to scan them over and write a php script to delete the users from the database ?) I need to know if there is any function in the PHP that can check the existence of the email address on the fly ? so that i can set the email send function in the mailer class to check before it sends out. On the server will bouncing emails are going to eatup lots of server resources ? like memory/cpu on processing them ? or are they are minimal where we dont have to worry about this at all ? May be a opensoruce or linux software to capture them and view them in a report basis and cleaning them up ? I am not a linux expert or server admin but i do lot of PHP coding, so please be descriptive of the solutions specially if they are linux commands Thank you!

• Got a malware on my hosting provider which infect JavaScript files .. how do I find the entry point?

  - by h3.

  This morning some sites which are hosted on the server as me started triggering malware alerts and started to redirect traffic to external sites. I've found out that a line of packed javascript was added to many js files across the server. What the script does is pretty simple, but what I would like to know is if this malware is well known and how it infect servers and propagate. For the curious here's the javascript line in question:

• Understanding !d command in sed with respect to saves

  - by richardh

  I have a directory of tab-delimited text files and some have comments in the first few lines that I would like to delete. I know that the first good line starts with "Mark" so I can use /^Mark/,$!d to delete these comments. After this deletion I have several other replacements that I make in the (new) first line that has variable names. My question is, why do I have to save sed's output to get my script to work? I understand that if I line is deleted, then the output doesn't proceed downstream because there is no output. But if I don't delete (i.e., !d) then why do I have to save to file? Thanks! Here is my shell script. (I'm a sed newbie, so any other feedback is also appreciated.) #!/bin/bash for file in *.txt; do mv $file $file.old1 sed -e '/^Mark/,$!d' $file.old1 > $file.old2 sed -e '1s/\([Ss]\)hareholder/\1hrhldr/g'\ -e '1s/\([Ii]\)mmediate/\1mmdt/g'\ -e '1s/\([Nn]\)umber/\1o/g'\ -e '1s/\([Cc]\)ompany/\1o/g'\ -e '1s/\([Ii]\)nformation/\1nfo/g'\ -e '1s/\([Pp]\)ercentage/\1ct/g'\ -e '1s/\([Dd]\)omestic/\1om/g'\ -e '1s/\([Gg]\)lobal/\1lbl/g'\ -e '1s/\([Cc]\)ountry/\1ntry/g'\ -e '1s/\([Ss]\)ource/\1rc/g'\ -e '1s/\([Oo]\)wnership/\1wnrshp/g'\ -e '1s/\([Uu]\)ltimate/\1ltmt/g'\ -e '1s/\([Ii]\)ncorporation/\1ncorp/g'\ -e '1s/\([Tt]\)otal/\1ot/g'\ -e '1s/\([Dd]\)irect/\1ir/g'\ $file.old2 > $file rm -f $file.old* done

• Not able to connect to port different than 22 - OpenVPN

  - by t8h7gu

  I have OpenVPN network with 5 clients. Computer with Arch Linux which hosts OpenVPN server, It also hosts virtual machine with Computer with CentOS which is also connnected to OpenVPN subnet. Windows 8 which hosts virtual machine with CentOS. Both of them are connected to OpenVPN. Last one machine is virtual machine with CentOS which is hosted by computer with Ubuntu 14( which is not connected to OpenVPN. All machines in OpenVPN subnet are bolded. All phisical computers are in different networks. The problem is that when I use nmap to scan Windows and it's guest virtual machine it's saids that host seems down. When I force namp to scan specific port it shows filtered state: nmap -Pn -p 50010 n3 Starting Nmap 6.46 ( http://nmap.org ) at 2014-06-07 19:49 CEST Nmap scan report for n3 (10.8.0.3) Host is up (0.11s latency). rDNS record for 10.8.0.3: node3.com PORT STATE SERVICE 50010/tcp filtered unknown Telnet also cannot connect to this port telnet n3 50010 Trying 10.8.0.3... telnet: Unable to connect to remote host: No route to host But ss on this host show's proper state of this port ss -anp | grep 50010 LISTEN 0 50 10.8.0.3:50010 *:* users:(("java",12310,271)) What might be possible reason of that and how to fix it? EDIT I've found that I am able to connect via telnet to ssh port: telnet n3 22 Trying 10.8.0.3... Connected to n3. Escape character is '^]'. SSH-2.0-OpenSSH_5.3 So it seems that it's not problem with Windows firewall. But I have no idea what it might be. Also nmap result for first thousand ports: nmap -Pn -p 1-1000 n3 Starting Nmap 6.46 ( http://nmap.org ) at 2014-06-07 20:08 CEST Nmap scan report for n3 (10.8.0.3) Host is up (0.49s latency). rDNS record for 10.8.0.3: node3.com Not shown: 999 filtered ports PORT STATE SERVICE 22/tcp open ssh Nmap done: 1 IP address (1 host up) scanned in 77.87 seconds

• Postgres cannot connect to server

  - by user1408935

  Super stumped by why Postgres isn't working on a new app I just started. I've got it working for one app already. I'm using postgres.app, and it's running. I started a new app with rails new depot -d postgresql and then I went into the database.yml file and changed username to my $USER (which is what it is for the other app, which is working). So now my database.yml file has this development section: development: adapter: postgresql encoding: unicode database: depot_development pool: 5 username: <username> password: But when I run "rake

In the same psql environment, I tried CREATE DATABASE depot; I've made sure that the pg gem is installed with bundle install, I've run "pg_ctl start", to which I got this response: pg_ctl: no database directory specified and environment variable PGDATA unset I ran "ps aux | grep postgres" to make sure postgres was running, to which I got this in return (which looks like it's doing OK, right?): <username> 10390 0.4 0.0 2425480 180 s000 R+ 6:15PM 0:00.00 grep postgres <username> 2907 0.0 0.0 2441604 464 ??

Any ideas? I'd really appreciate it, cause I'm pretty new to Rails, and this is a pretty disheartening roadblock. Thanks! EDIT -- Per request, posting the successful database.yml . It seems the difference is the inclusion of a password: development: adapter: postgresql encoding: unicode database: *******_development pool: 5 username: ******* password: ******* EDIT2 -- When I add a password to the .yml file, then run rake db:create again, I get this error. rake aborted! No Rakefile found (looking for: rakefile, Rakefile, rakefile.rb, Rakefile.rb)
